Fund Overview

iSHARES® FTSE CHINA (HK LISTED)
INDEX FUND

Ticker: FCHI Stock Exchange: NASDAQ

Investment Objective

The iShares FTSE China (HK Listed) Index Fund (the “Fund”) seeks investment results that correspond generally to the price and yield performance, before fees and expenses, of the FTSE China (HK Listed) Index (the “Underlying Index”).

Fees and Expenses

The following table describes the fees and expenses that you will incur if you own shares of the Fund. The investment advisory agreement between iShares Trust (the “Trust”) and BlackRock Fund Advisors (“BFA”) (the “Investment Advisory Agreement”) provides that BFA will pay all operating expenses of the Fund, except interest expenses, taxes, brokerage expenses, future distribution fees or expenses, and extraordinary expenses.

You may also incur usual and customary brokerage commissions when buying or selling shares of the Fund, which are not reflected in the example that follows:

Annual Fund Operating Expenses

percentage of the value of your investments)

Fund
Operating
Expenses
0.72% None None 0.72%

Example. This Example is intended to help you compare the cost of owning shares of the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

1 Year
3 Years
5 Years
10 Years
$74 $230 $401 $894

Portfolio Turnover. The Fund may pay transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 8% of the average value of its portfolio.

Principal Investment Strategies

The Underlying Index is designed to track the performance of the large- and mid-capitalization companies in the Chinese equity market that are available to international investors. The Underlying Index consists of many of the largest and most liquid Chinese companies. Securities in the Underlying Index are weighted based on the total market value of their shares so that securities with higher total market values generally have a higher representation in the Underlying Index. Each security in the Underlying Index is a current constituent of the FTSE All-World Index and all of the securities in the Underlying Index currently trade on the Hong Kong Stock Exchange. As of September 28, 2011, the Underlying Index consisted of 112 companies. Component companies include financial, oil & gas and telecommunication companies.

BFA uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to “beat” the index it tracks and does not seek temporary defensive positions when markets decline or appear overvalued.

Indexing may eliminate the chance that the Fund will substantially outperform the Underlying Index but also may reduce some of the risks of active management, such as poor security selection. Indexing seeks to achieve lower costs and better after-tax performance by keeping portfolio turnover low in comparison to actively managed investment companies.

BFA uses a representative sampling indexing strategy to manage the Fund. “Representative sampling” is an indexing strategy that involves investing in a representative sample of securities that collectively has an investment profile similar to the Underlying Index. The securities selected are expected to have, in the aggregate, investment characteristics (based on factors such as market capitalization and industry weightings), fundamental characteristics (such as return variability and yield) and liquidity measures similar to those of the Underlying Index. The Fund may or may not hold all of the securities in the Underlying Index.

The Fund generally invests at least 90% of its assets in securities of the Underlying Index and in depositary receipts representing securities of the Underlying Index. The Fund may invest the remainder of its assets in securities not included in the Underlying Index, but which BFA believes will help the Fund track the Underlying Index and in other investments including futures contracts, options on futures contracts, options and swaps as well as cash and cash equivalents, including shares of

S-2   


Table Of Contents



money market funds advised by BFA or its affiliates.

The Fund may lend securities representing up to one-third of the value of the Fund’s total assets (including the value of the collateral received).

The Underlying Index is sponsored by an organization (the “Index Provider”) that is independent of the Fund and BFA. The Index Provider determines the composition and relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index. The Fund’s Index Provider is FTSE International Limited (“FTSE”).

Industry Concentration Policy. The Fund will concentrate its investments (i.e., hold 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. For purposes of this limitation, securities of the U.S. government (including its agencies and instrumentalities) and repurchase agreements collateralized by U.S. government securities are not considered to be issued by members of any industry.

Summary of Principal Risks

As with any investment, you could lose all or part of your investment in the Fund, and the Fund’s performance could trail that of other investments. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund’s net asset value per share (“NAV”), trading price, yield, total return and ability to meet its investment objective.

Asset Class Risk. Securities in the Underlying Index or in the Fund’s portfolio may underperform in comparison to the general securities markets or other asset classes.

Concentration Risk. To the extent that the Fund’s investments are concentrated in China, a particular issuer, market, industry or asset class, the Fund may be susceptible to loss due to adverse occurrences affecting China, a particular issuer, market, industry or asset class.

Currency Risk. Because the Fund’s NAV is determined in U.S. dollars, the Fund’s NAV could decline if the currency of a non-U.S. market in which the Fund invests depreciates against the U.S. dollar.

Custody Risk. Less developed markets are more likely to experience problems with the clearing and settling of trades and the holding of securities by local banks, agents and depositories.

Emerging Markets Risk. The Fund’s investments in China may be subject to a greater risk of loss than investments in more developed markets. Emerging markets may be more likely to experience inflation risk, political turmoil and rapid changes in economic conditions than more developed markets. Emerging markets often have less uniformity in accounting and reporting requirements, unreliable securities valuation and greater risk associated with custody of securities.

Equity Securities Risk. Equity securities are subject to changes in value and their values may be more volatile than other asset classes.

Financial Sector Risk. Performance of companies in the financial sector may be adversely impacted by many factors, including, among others, government regulations, economic conditions, credit

S-3   


Table Of Contents



rating downgrades, changes in interest rates, and decreased liquidity in credit markets. Market conditions and regulation in China may be particularly subject to change based on government policy. This sector has experienced significant losses in the recent past, and the impact of more stringent capital requirements and of recent or future regulation on any individual financial company or on the sector as a whole cannot be predicted.

Geographic Risk. A natural or other disaster could occur in China, causing an adverse impact on the Fund and the companies to which it has exposure.

Issuer Risk. Fund performance depends on the performance of individual securities to which the Fund has exposure. Changes to the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA’s investment management strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares, losses from trading in secondary markets, periods of high volatility and disruption in the creation/redemption process of the Fund. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV.

Mid-Capitalization Companies Risk. The Fund may invest in the securities of mid-capitalization companies. Compared to large-capitalization companies, mid-capitalization companies may be less stable and more susceptible to adverse developments and their securities may be more volatile and less liquid.

Non-Diversification Risk. The Fund may invest a large percentage of its assets in securities issued by or representing a small number of issuers. As a result, the Fund’s performance may depend on the performance of a small number of issuers.

Non-U.S. Securities Risk. Investments that track the value of Chinese issuers are subject to the risks associated with investing in China, such as heightened risks of inflation or nationalization. The Fund may lose money due to political, economic and geographic events affecting a non-U.S. issuer or market. The Fund is specifically exposed to Asian Economic Risk.

Oil and Gas Sector Risk. Companies in the oil and gas sector are affected by worldwide energy prices, exploration and production costs. Companies in the oil and gas sector may have significant operations in areas at risk for natural disasters, social unrest and environmental damage. These companies may also be at risk for increased government regulation and intervention, litigation, and negative publicity and perception.

Passive Investment Risk. The Fund is not actively managed and BFA does not attempt to take defensive positions under any market conditions, including declining markets.

Privatization Risk. The country in which the Fund invests has begun a process of

S-4   


Table Of Contents



privatizing certain entities and industries. Privatized entities may lose money or be re-nationalized.

Reliance on Trading Partners Risk. The Fund invests in an economy that is heavily dependent upon trading with key partners. Any reduction in this trading may have an adverse impact on the Fund’s investments. Through its trading partners, the Fund is particularly exposed to U.S. Trading Partner Risk.

Risk of Investing in China. China may be subject to considerable degrees of economic, political and social instability.

Securities Lending Risk. The Fund may engage in securities lending. Securities lending involves the risk that the Fund may lose money because the borrower of the Fund’s loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Security Risk. The country in which the Fund invests has experienced security concerns. Incidents involving the country’s or region’s security may cause uncertainty in these markets and may adversely affect their economies and the Fund’s investments.

Telecommunications Sector Risk. Companies in the telecommunications sector may be affected by industry competition, substantial capital requirements, government regulation and obsolescence of telecommunications products and services due to technological advancement.

Tracking Error Risk. The performance of the Fund may diverge from that of the Underlying Index. Because the Fund employs a representative sampling strategy, the Fund may experience tracking error to a greater extent than a fund that seeks to replicate an index.

Valuation Risk. The value of the securities in the Fund’s portfolio may change on days when shareholders will not be able to purchase or sell the Fund’s shares.

1 After-tax returns in the table above are calculated using the historical highest individual U.S. federal marginal income tax rates and do not reflect the impact of state or local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown, and after-tax returns shown are not relevant to tax-exempt investors or investors who hold shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts (“IRAs”). Fund returns after taxes on distributions and sale of Fund shares are calculated assuming that an investor has sufficient capital gains of the same character from other investments to offset any capital losses from the sale of Fund shares. As a result, Fund returns after taxes on distributions and sale of Fund shares may exceed Fund returns before taxes and/or returns after taxes on distributions.

Management

Investment Adviser. BlackRock Fund Advisors.

Portfolio Managers. Christopher Bliss, Rene Casis, Diane Hsiung and Greg Savage (the “Portfolio Managers”) are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager supervises a portfolio management team. Mr. Bliss has been a Portfolio Manager of the Fund since 2011. Mr. Casis has been a Portfolio Manager of the Fund since 2010. Ms. Hsiung and Mr. Savage have been Portfolio Managers of the Fund since 2008.

Purchase and Sale of Fund Shares

The Fund is an exchange-traded fund (commonly referred to as an “ETF”). Individual Fund shares may only be purchased and sold on a national securities exchange through a broker-dealer. The price of Fund shares is based on market price, and because ETF shares trade at market prices rather than NAV, shares may trade at a price greater than NAV (a premium) or less than NAV (a discount). The Fund will only issue or redeem shares that have been aggregated into blocks of 100,000 shares or multiples thereof (“Creation Units”) to authorized participants who have entered into agreements with the Fund’s distributor. The Fund generally will issue or redeem Creation Units in return for a designated portfolio of securities (and an amount of cash) that the Fund specifies each day.

Tax Information

The Fund intends to make distributions that may be taxable to you as ordinary income or capital gains, unless you are investing through a tax-deferred arrangement such as a 401(k) plan or an IRA.

Payments to Broker-Dealers and other Financial Intermediaries

If you purchase shares of the Fund through a broker-dealer or other financial intermediary (such as a bank), BFA or other related companies may pay the intermediary for marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems or other services related to the sale or promotion of the Fund. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.

More Information About the Fund

This Prospectus contains important information about investing in the Fund. Please read this Prospectus carefully before you make any investment decisions. Additional information regarding the Fund is available at www.iShares.com.

BFA is the investment adviser to the Fund. Shares of the Fund are listed for trading on The NASDAQ Stock Market (“NASDAQ”). The market price for a share of the Fund may be different from the Fund’s most recent NAV.

ETFs are funds that trade like other publicly-traded securities. The Fund is designed to track an index. Similar to shares of an index mutual fund, each share of the Fund represents a partial ownership in an underlying portfolio of securities intended to track a market index. Unlike shares of a mutual fund, which can be bought and redeemed from the issuing fund by all shareholders at a price based on NAV, shares of the Fund may be purchased or redeemed directly from the Fund at NAV solely by authorized participants. Also unlike shares of a mutual fund, shares of the Fund are listed on a national securities exchange and trade in the secondary market at market prices that change throughout the day.

The Fund invests in a particular segment of the securities markets and seeks to track the performance of a securities index that generally is not representative of the market as a whole. The Fund is designed to be used as part of broader asset allocation strategies. Accordingly, an investment in the Fund should not constitute a complete investment program.

An index is a theoretical financial calculation while the Fund is an actual investment portfolio. The performance of the Fund and the Underlying Index may vary due to transaction costs, non-U.S. currency valuations, asset valuations, corporate actions (such as mergers and spin-offs), timing variances and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions (such as diversification requirements) that apply to the Fund but not to the Underlying Index or to the use of representative sampling. “Tracking error” is the difference between the performance (return) of the Fund’s portfolio and that of the Underlying Index. BFA expects that, over time, the Fund’s tracking error will not exceed 5%. Because the Fund uses a representative sampling indexing strategy, it can be expected to have a larger tracking error than if it used a replication indexing strategy. “Replication” is an indexing strategy in which a fund invests in substantially all of the securities in its underlying index in approximately the same proportions as in the underlying index.

An investment in the Fund is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, BFA or any of its affiliates.

The Fund’s investment objective and the Underlying Index may be changed without shareholder approval.

A Further Discussion of Principal Risks

The Fund is subject to various risks, including the principal risks noted below, any of which may adversely affect the Fund’s NAV, trading price, yield, total return and ability to meet its investment objective. You could lose all or part of your investment in the Fund, and the Fund could underperform other investments.

Asian Economic Risk. Certain Asian economies have experienced over-extension of credit, currency devaluations and restrictions, high unemployment, high inflation, decreased exports and economic recessions. Economic events in any one Asian country may have a significant economic effect on the entire Asian region, and any adverse events in the Asian markets may have a significant adverse effect on Chinese companies.

Asset Class Risk. The securities in the Underlying Index or in the Fund’s portfolio may underperform the returns of other securities or indexes that track other countries, groups of countries, regions, industries, groups of industries, markets, asset classes or sectors. Various types of securities or indexes tend to experience cycles of outperformance and underperformance in comparison to the general securities markets.

Concentration Risk. To the extent that the Fund’s portfolio reflects the Underlying Index’s concentration in the securities of a particular issuer or issuers in a particular country, group of countries, market, industry, group of industries, sector or asset class, the Fund may be adversely affected by the performance of those securities, may be subject to increased price volatility and may be more susceptible to adverse economic, market, political or regulatory occurrences affecting that issuer, country, group of countries, market, industry, group of industries, sector or asset class.

Currency Risk. Because the Fund’s NAV is determined on the basis of the U.S. dollar, investors may lose money if the currency of a non-U.S. market in which the Fund invests depreciates against the U.S. dollar, even if the local currency value of the Fund’s holdings in that market increases.

Custody Risk. Custody risk refers to the risks inherent in the process of clearing and settling trades and the holding of securities by local banks, agents and depositories. Low trading volumes and volatile prices in less developed markets may make trades harder to complete and settle, and governments or trade groups may compel local agents to hold securities in designated depositories that are not subject to independent evaluation. Local agents are held only to the standards of care of their local markets. In general, the less developed a country’s securities market is, the greater the likelihood of custody problems.

Emerging Markets Risk. China is one of the largest global emerging markets. Investments in emerging markets are subject to a greater risk of loss than investments in more developed markets. This is due to, among other things, greater market volatility, lower trading volume, political and economic instability, greater risk of a market shutdown and more governmental limitations on foreign investments than typically found in more developed markets.

Equity Securities Risk. The Fund invests in equity securities, which are subject to changes in value that may be attributable to market perception of a particular issuer or to general stock market fluctuations that affect all issuers. Investments in equity securities may be more volatile than investments in other asset classes.

Financial Sector Risk. Companies in the financial sector of an economy are often subject to governmental regulation and, recently, government intervention and the potential for additional regulation, which may adversely affect the scope of their activities, the prices they can charge and the amount of capital they must maintain. Governmental regulation may change frequently and may have significant adverse consequences for companies in the financial sector, including effects not intended by such regulation. The impact of recent or future regulation in various countries on any individual financial company or on the sector as a whole cannot be predicted. Certain risks may impact the value of investments in the financial sector more severely than investments outside this sector, including the risks associated with companies that operate with substantial financial leverage. Companies in the financial sector may also be adversely affected by increases in interest rates and loan losses, decreases in the availability of money or asset valuations, credit rating downgrades and adverse conditions in other related markets. Over the past few years, the deterioration of the credit markets has impacted a broad range of mortgage, asset-backed, auction rate, sovereign debt and other markets, including U.S. and non-U.S. credit and interbank money markets, thereby affecting a wide range of financial institutions and markets. This situation has created instability in the financial markets and caused certain financial companies to incur large losses. Some financial companies have experienced declines in the valuations of their assets, taken actions to raise capital (such as the issuance of debt or equity securities), or even ceased operations. Some financial companies have borrowed significant amounts of capital from governments and may face future government-imposed restrictions on their businesses or increased government intervention. These actions have caused the securities of many financial companies to decline in value. Insurance companies, in particular, may be subject to severe price competition, which may have an adverse impact on their profitability. Chinese financial sector regulation and ownership may be more intrusive than in the United States and other developed countries, especially with respect to the regulation of non-Chinese banks and other non-Chinese financial companies. Greater Chinese governmental involvement in the financial sector may pose additional risks for investors. Market conditions and regulation in China may be particularly subject to change based on government policy.

Geographic Risk. China historically has experienced natural disasters such as earthquakes, droughts and floods and is economically sensitive to environmental events. Any such event could cause a significant impact on the Chinese economy.

Issuer Risk. The performance of the Fund depends on the performance of individual securities to which the Fund has exposure. Any issuer of these securities may perform poorly, causing the value of its securities to decline. Poor performance may be caused by poor management decisions, competitive pressures, changes in technology, expiration of patent protection, disruptions in supply, labor problems or shortages, corporate restructurings, fraudulent disclosures or other factors. Issuers may, in times

of distress or at their own discretion, decide to reduce or eliminate dividends, which may also cause their stock prices to decline.

Management Risk. The Fund may not fully replicate the Underlying Index and may hold securities not included in the Underlying Index. As a result, the Fund is subject to the risk that BFA’s investment management strategy, the implementation of which is subject to a number of constraints, may not produce the intended results.

Market Risk. The Fund could lose money due to short-term market movements and over longer periods during market downturns. Securities may decline in value due to factors affecting securities markets generally or particular industries represented in the markets. The value of a security may decline due to general market conditions, economic trends or events that are not specifically related to the issuer of the security or to factors that affect a particular industry or industries. During a general downturn in the securities markets, multiple asset classes may be negatively affected.

Market Trading Risk

Absence of Active Market. Although shares of the Fund are listed for trading on one or more stock exchanges, there can be no assurance that an active trading market for such shares will develop or be maintained.

Risk of Secondary Listings. The Fund’s shares may be listed or traded on U.S. and non-U.S. stock exchanges other than the U.S. stock exchange where the Fund’s primary listing is maintained. There can be no assurance that the Fund’s shares will continue to trade on any such stock exchange or in any market or that the Fund’s shares will continue to meet the requirements for listing or trading on any exchange or in any market. The Fund’s shares may be less actively traded in certain markets than others, and investors are subject to the execution and settlement risks and market standards of the market where they or their broker direct their trades for execution. Certain information available to investors who trade Fund shares on a U.S. stock exchange during regular U.S. market hours may not be available to investors who trade in other markets, which may result in secondary market prices in such markets being less efficient.

Secondary Market Trading Risk. Shares of the Fund may trade in the secondary market at times when the Fund does not accept orders to purchase or redeem shares. At such times, shares may trade in the secondary market with more significant premiums or discounts than might be experienced at times when the Fund accepts purchase and redemption orders.

Secondary market trading in Fund shares may be halted by a stock exchange because of market conditions or other reasons. In addition, trading in Fund shares on a stock exchange or in any market may be subject to trading halts caused by extraordinary market volatility pursuant to “circuit breaker” rules on the stock exchange or market. There can be no assurance that the requirements necessary to maintain the listing or trading of Fund shares will continue to be met or will remain unchanged.

Shares of the Fund May Trade at Prices Other Than NAV. Shares of the Fund trade on stock exchanges at prices at, above or below their most recent NAV. The NAV of the Fund is calculated at the end of each business day and fluctuates with changes in the market value of the Fund’s holdings since the most recent calculation. The trading

prices of the Fund’s shares fluctuate continuously throughout trading hours based on market supply and demand rather than NAV. The trading prices of the Fund’s shares may deviate significantly from NAV during periods of market volatility. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV. However, because shares can be created and redeemed in Creation Units at NAV (unlike shares of many closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their NAVs), BFA believes that large discounts or premiums to the NAV of the Fund are not likely to be sustained over the long-term. While the creation/redemption feature is designed to make it likely that the Fund’s shares normally will trade on stock exchanges at prices close to the Fund’s next calculated NAV, exchange prices are not expected to correlate exactly with the Fund’s NAV due to timing reasons as well as market supply and demand factors. In addition, disruptions to creations and redemptions or extreme market volatility may result in trading prices for shares of the Fund that differ significantly from its NAV.

Costs of Buying or Selling Fund Shares. Buying or selling Fund shares on an exchange involves two types of costs that apply to all securities transactions. When buying or selling shares of the Fund through a broker, you will likely incur a brokerage commission or other charges imposed by brokers as determined by that broker. In addition, you may incur the cost of the “spread” – that is, the difference between what investors are willing to pay for Fund shares (the “bid” price) and the price at which they are willing to sell Fund shares (the “ask” price). Because of the costs inherent in buying or selling Fund shares, frequent trading may detract significantly from investment results and an investment in Fund shares may not be advisable for investors who anticipate regularly making small investments.

Mid-Capitalization Companies Risk. Many of the companies in which the Fund invests are considered mid-capitalization companies. Stock prices of mid-capitalization companies may be more volatile than those of large-capitalization companies and, therefore, the Fund’s share price may be more volatile than those of funds that invest a larger percentage of their assets in stocks issued by large-capitalization companies. Stock prices of mid-capitalization companies are also more vulnerable than those of large-capitalization companies to adverse business or economic developments, and the stocks of mid-capitalization companies may be less liquid, making it difficult for the Fund to buy and sell them. In addition, mid-capitalization companies generally have less diverse product lines than large-capitalization companies and are more susceptible to adverse developments related to their products.

Non-Diversification Risk. The Fund is classified as “non-diversified.” This means that the Fund may invest a large percentage of its assets in securities issued by or representing a small number of issuers. As a result, the Fund may be more susceptible to the risks associated with these particular issuers, or to a single economic, political or regulatory occurrence affecting these issuers.

Non-U.S. Securities Risk. Investments that track the value of Chinese issuers are subject to all of the risks of investing in China, including heightened risks of inflation or nationalization and market fluctuations caused by economic and political

developments. As a result of investing in securities that track the value of Chinese issuers, the Fund may be subject to increased risk of loss caused by any of the factors listed below:

  • Lower levels of liquidity and market efficiency;
  • Greater securities price volatility;
  • Exchange rate fluctuations and exchange controls;
  • Less availability of public information about issuers;
  • Limitations on foreign ownership of securities;
  • Imposition of withholding or other taxes;
  • Imposition of restrictions on the expatriation of the funds or other assets of the Fund;
  • Higher transaction and custody costs and delays in settlement procedures;
  • Difficulties in enforcing contractual obligations;
  • Lower levels of regulation of the securities market;
  • Weaker accounting, disclosure and reporting requirements; and
  • Legal principles related to corporate governance, directors’ fiduciary duties and liabilities and stockholders’ rights in markets in which the Fund invests may differ and/or may not be as extensive or protective as those that apply in the United States.

Oil and Gas Sector Risk. The profitability of companies in the oil and gas sector is related to worldwide energy prices, exploration, and production spending. Companies in the oil and gas sector may be adversely affected by natural disasters or other catastrophes. Companies in the oil and gas sector may be at risk for environmental damage claims and other types of litigation. Companies in the oil and gas sector may be adversely affected by changes in exchange rates, interest rates, changes in prices for competitive energy services, economic conditions, tax treatment, government regulation and intervention, negative perception and world events in the regions where companies operate (e.g., expropriation, nationalization, confiscation of assets and property or imposition of restrictions on foreign investments and repatriation of capital, military coups, social unrest, violence or labor unrest). Companies in the oil and gas sector may have significant capital investments in, or engage in transactions involving, emerging market countries, which may heighten these risks.

Passive Investment Risk. The Fund is not actively managed and may be affected by a general decline in market segments related to the Underlying Index. The Fund invests in securities included in, or representative of, the Underlying Index regardless of their investment merits. BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

Privatization Risk. China has begun a process of privatization of certain entities and industries. In some instances, investors in newly privatized entities have suffered losses due to the inability of the newly privatized entities to adjust quickly to a competitive environment or changing regulatory and legal standards or, in some cases,

due to re-nationalization of such privatized entities. There is no assurance that such losses will not recur.

Reliance on Trading Partners Risk. Export growth continues to be a major driver of China’s rapid economic growth. To increase exports, China has pursued policies such as liberalizing trading rights and encouraging foreign companies to conduct manufacturing and assembly operations in China. Reduction in spending on Chinese products and services, institution of tariffs or other trade barriers or a downturn in any of the economies of China’s key trading partners may have an adverse impact on the companies in which the Fund invests.

U.S. Trading Partners Risk. The United States is a significant trading partner of or foreign investor in China. Decreasing U.S. imports, new trade regulations, changes in the U.S. dollar exchange rate or a recession in the United States may have a material adverse effect on economies of the countries in which the Fund invests.

Risk of Investing in China. The Chinese economy is subject to a considerable degree of economic, political and social instability:

Political and Social Risk. The Chinese government is authoritarian and has periodically used force to suppress civil dissent. Disparities of wealth and the pace of economic liberalization may lead to social turmoil, violence and labor unrest. In addition, China continues to experience disagreements related to integration with Hong Kong and religious and nationalist disputes in Tibet and Xinjiang. There is also a greater risk involved in currency fluctuations, currency convertibility, interest rate fluctuations and higher rates of inflation as a result of internal social unrest or conflicts with other countries. Unanticipated political or social developments may result in sudden and significant investment losses. China’s growing income inequality and worsening environmental conditions also are factors that may affect the Chinese economy.

Government Control and Regulations. The Chinese government has implemented significant economic reforms in order to liberalize trade policy, promote foreign investment in the economy, reduce government control of the economy and develop market mechanisms. There can be no assurance these reforms will continue or that they will be effective. Despite recent reform and privatizations, significant regulation of investment and industry is still pervasive and the Chinese government may restrict foreign ownership of Chinese corporations and repatriation of assets. Chinese markets generally continue to experience inefficiency, volatility and pricing anomalies that may be connected to governmental influence, a lack of publicly-available information, and political and social instability.

Economic Risk. The Chinese economy has grown rapidly during the past several years and there is no assurance that this growth rate will be maintained. China may experience substantial rates of inflation or economic recessions, causing a negative effect on the economy and securities market. Delays in enterprise restructuring, slow development of well-functioning financial markets and widespread corruption have also hindered performance of the Chinese economy. China continues to receive substantial pressure from trading partners to liberalize official currency exchange rates.

Expropriation Risk. The Chinese government maintains a major role in economic policymaking and investing in China involves risk of loss due to expropriation, nationalization, or confiscation of assets and property or the imposition of restrictions on foreign investments and on repatriation of capital invested.

Hong Kong Political Risk. Hong Kong reverted to Chinese sovereignty on July 1, 1997 as a Special Administrative Region (SAR) of the People’s Republic of China (“PRC”) under the principle of “one country, two systems.” Although China is obligated to maintain the current capitalist economic and social system of Hong Kong through June 30, 2047, the continuation of economic and social freedoms enjoyed in Hong Kong is dependent on the government of China. Any attempt by China to tighten its control over Hong Kong’s political, economic, legal or social policies may result in an adverse effect on Hong Kong’s markets. In addition, the Hong Kong dollar trades at a fixed exchange rate in relation to (or, is “pegged” to) the U.S. dollar, which has contributed to the growth and stability of the Hong Kong economy. However, it is uncertain how long the currency peg will continue or what effect the establishment of an alternative exchange rate system would have on the Hong Kong economy. Because the Fund’s NAV is denominated in U.S. dollars, the establishment of an alternative exchange rate system could result in a decline in the Fund’s NAV.

Securities Lending Risk. The Fund may engage in securities lending. Securities lending involves the risk that the Fund may lose money because the borrower of the Fund’s loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for the loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Security Risk. China has strained international relations with Taiwan, India, Russia and other neighbors due to territorial disputes, historical animosities and other defense concerns. Relations between China’s Han ethnic majority and other ethnic groups in China, including Tibetans and Uighurs, are also strained and have been marked by protests and violence. These situations may cause uncertainty in the Chinese market and may adversely affect the performance of the Chinese economy.

Telecommunications Sector Risk. The telecommunications sector of an economy is often subject to extensive government regulation. The costs of complying with governmental regulations, delays or failure to receive required regulatory approvals, or the enactment of new adverse regulatory requirements may negatively affect the business of the telecommunications companies. Government actions around the world, specifically in the area of pre-marketing clearance of products and prices, can be arbitrary and unpredictable. Companies in the telecommunications sector may encounter distressed cash flows due to the need to commit substantial capital to meet increasing competition, particularly in formulating new products and services using new technology. Technological innovations may make the products and services of telecommunications companies obsolete.

Tracking Error Risk. Imperfect correlation between the Fund’s portfolio securities and those in the Underlying Index, rounding of prices, changes to the Underlying Index and regulatory requirements may cause tracking error, which is the divergence of the

Fund’s performance from that of the Underlying Index. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Underlying Index does not. Because the Fund employs a representative sampling strategy, the Fund may experience tracking error to a greater extent than a fund that seeks to replicate an index.

Valuation Risk. Because non-U.S. exchanges may be open on days when the Fund does not price its shares, the value of the securities in the Fund’s portfolio may change on days when shareholders will not be able to purchase or sell the Fund’s shares. In addition, for purposes of calculating the Fund’s NAV, the value of assets denominated in non-U.S. currencies is converted into U.S. dollars using exchange rates deemed appropriate by BFA. This conversion may result in a difference between the prices used to calculate the Fund’s NAV and the prices used by the Underlying Index, which, in turn, could result in a difference between the Fund’s performance and the performance of the Underlying Index.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

Basic Materials Sector Risk. Issuers in the basic materials sector could be adversely affected by commodity price volatility, exchange rates, import controls and increased competition. Production of industrial materials often exceeds demand as a result of over-building or economic downturns, leading to poor investment returns. Issuers in the basic materials sector are at risk for environmental damage and product liability claims and may be adversely affected by depletion of resources, delays in technical progress, labor relations and government regulations.

Industrials Sector Risk. The stock prices of companies in the industrials sector are affected by supply and demand, both for their specific product or service and for industrials sector products in general. The products of manufacturing companies may face obsolescence due to rapid technological developments and frequent new product introduction. Government regulations, world events, economic conditions and exchange rates affect the performance of companies in the industrials sector. Companies in the industrials sector may be adversely affected by liability for environmental damage, product liability claims and exchange rates. The industrials sector may also be adversely affected by changes or trends in commodity prices, which may be influenced by unpredictable factors.

Portfolio Holdings Information

A description of the Trust’s policies and procedures with respect to the disclosure of the Fund’s portfolio securities is available in the Fund’s Statement of Additional Information (“SAI”). The top holdings of the Fund can be found at www.iShares.com. Fund fact sheets provide information regarding the Fund’s top holdings and may be requested by calling 1-800-iShares (1-800-474-2737).

Management

Investment Adviser. As investment adviser, BFA has overall responsibility for the general management and administration of the Trust. BFA provides an investment program for the Fund and manages the investment of the Fund’s assets. In managing the Fund, BFA may draw upon the research and expertise of its asset management affiliates with respect to certain portfolio securities. In seeking to achieve the Fund’s investment objective, BFA uses teams of portfolio managers, investment strategists and other investment specialists. This team approach brings together many disciplines and leverages BFA’s extensive resources.

Pursuant to the Investment Advisory Agreement between BFA and the Trust (entered into on behalf of the Fund), BFA is responsible for substantially all expenses of the Fund, except interest expenses, taxes, brokerage expenses, future distribution fees or expenses and extraordinary expenses.

For its investment advisory services to the Fund, BFA is entitled to receive a management fee from the Fund corresponding to the Fund’s allocable portion of an aggregate management fee based on the aggregate average daily net assets of the following iShares funds: iShares FTSE China 25 Index Fund and iShares FTSE China (HK Listed) Index Fund. The aggregate management fee is calculated as follows: 0.74% per annum of the aggregate net assets less than or equal to $6.0 billion, plus 0.67% per annum of the aggregate net assets over $6.0 billion up to and including $12.0 billion, plus 0.60% per annum of the aggregate net assets in excess of $12.0 billion.
As calculated on July 31, 2011, for its investment advisory services to the Fund, BFA is entitled to receive a management fee from the Fund, based on a percentage of the Fund’s average daily net assets, at an annual rate of 0.72%.

BFA is located at 400 Howard Street, San Francisco, CA 94105. It is a wholly owned subsidiary of BTC, which in turn is indirectly wholly-owned by BlackRock, Inc. (“BlackRock”). As of September 30, 2011, BTC and its affiliates, including BFA and BlackRock, provided investment advisory services for assets in excess of $3.35 trillion. BFA, BTC, BlackRock Execution Services, BlackRock and their affiliates deal, trade and invest for their own accounts in the types of securities in which the Fund may also invest.

A discussion regarding the basis for the Trust’s Board of Trustees’ (the “Board”) approval of the Investment Advisory Agreement with BFA is available in the Fund’s annual report for the period ended July 31.

Portfolio Managers. Christopher Bliss, Rene Casis, Diane Hsiung and Greg Savage are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager is responsible for various functions related to portfolio management, including, but not limited to, investing cash inflows, coordinating with members of his or her portfolio management team to focus on certain asset classes, implementing investment strategy, researching and reviewing investment strategy and overseeing members of his or her portfolio management team that have more limited responsibilities.

Christopher Bliss has been employed by BFA (formerly, Barclays Global Fund Advisors (“BGFA”)) and BTC (formerly, Barclays Global Investors, N.A. (“BGI”)) as a senior

portfolio manager since 2005. Prior to that, Mr. Bliss was a portfolio manager from 2004 to 2005 for BGFA and BGI. Mr. Bliss has been a Portfolio Manager of the Fund since 2011.

Rene Casis has been employed by BFA and BTC as a senior portfolio manager since 2009. From 2005 to 2009, Mr. Casis was a trader at Barclays Capital. Prior to that, Mr. Casis was a portfolio manager from 2000 to 2005 for BGFA and BGI. Mr. Casis has been a Portfolio Manager of the Fund since 2010.

Diane Hsiung has been employed by BFA and BTC as a senior portfolio manager since 2007. Prior to that, Ms. Hsiung was a portfolio manager from 2002 to 2006 for BGFA and BGI. Ms. Hsiung has been a Portfolio Manager of the Fund since 2008.

Greg Savage has been employed by BFA and BTC as a senior portfolio manager since 2006. Prior to that, Mr. Savage was a portfolio manager from 2001 to 2006 for BGFA and BGI. Mr. Savage has been a Portfolio Manager of the Fund since 2008.

The Fund’s SAI provides additional information about the Portfolio Managers’ compensation, other accounts managed by the Portfolio Managers and the Portfolio Managers’ ownership (if any) of shares in the Fund.

Administrator, Custodian and Transfer Agent. State Street Bank and Trust Company (“State Street”) is the administrator, custodian and transfer agent for the Fund.

Conflicts of Interest. BFA wants you to know that there are certain entities with which BFA has relationships that may give rise to conflicts of interest, or the appearance of conflicts of interest. These entities include the following: BFA’s affiliates (including BlackRock and The PNC Financial Services Group, Inc., and each of their affiliates, directors, partners, trustees, managing members, officers and employees (collectively, the “Affiliates”)) and BlackRock’s significant shareholder, Barclays Bank PLC and its affiliates, including Barclays PLC (each, an “Entity” and together, the “Entities”).

The activities of BFA, the Affiliates and the Entities in the management of, or their interest in, their own accounts and other accounts they manage, may present conflicts of interest that could disadvantage the Fund and its shareholders. BFA and its Affiliates or the Entities provide investment management services to other funds and discretionary managed accounts that may follow an investment program similar to that of the Fund. BFA, its Affiliates and the Entities are involved worldwide with a broad spectrum of financial services and asset management activities and may engage in the ordinary course of business in activities in which their interests or the interests of their clients may conflict with those of the Fund. BFA, one or more of the Affiliates or the Entities acts, or may act, as an investor, investment banker, research provider, investment manager, financier, underwriter, advisor, market maker, trader, prime broker, lender, agent or principal, and have other direct and indirect interests, in securities, currencies and other instruments in which the Fund may directly or indirectly invest. Thus, it is likely that the Fund will have multiple business relationships with and will invest in, engage in transactions with, make voting decisions with respect to, or obtain services from, entities for which BFA, an Affiliate or an Entity performs or seeks to perform investment banking or other services.

BFA or one or more Affiliates or Entities may engage in proprietary trading and advise accounts and funds that have investment objectives similar to those of the Fund and/or that engage in and compete for transactions in the same types of securities, currencies and other instruments as the Fund, including in securities issued by other open-end and closed-end investment management companies, including investment companies that are affiliated with the Fund and BFA, to the extent permitted under the Investment Company Act of 1940, as amended (the “1940 Act”). The trading activities of BFA, these Affiliates and Entities are carried out without reference to positions held directly or indirectly by the Fund and may result in BFA, an Affiliate or an Entity having positions that are adverse to those of the Fund.

No Affiliate or Entity is under any obligation to share any investment opportunity, idea or strategy with the Fund. As a result, an Affiliate or an Entity may compete with the Fund for appropriate investment opportunities. As a result of this and several other factors, the results of the Fund’s investment activities may differ from those of an Affiliate or an Entity and of other accounts managed by an Affiliate or an Entity, and it is possible that the Fund could sustain losses during periods in which one or more Affiliates or Entities and other accounts achieve profits on their trading for proprietary or other accounts. The opposite result is also possible.

The Fund may, from time to time, enter into transactions in which BFA or an Affiliate’s or an Entity’s clients have an interest adverse to the Fund. Furthermore, transactions undertaken by Affiliate-advised clients may adversely impact the Fund. Transactions by one or more Affiliate- or Entity-advised clients or BFA may have the effect of diluting or otherwise disadvantaging the values, prices or investment strategies of the Fund.

An Entity may maintain securities indices as part of its product offerings. Index-based funds seek to track the performance of securities indices and may use the name of the index in the fund name. Index providers, including the Entities, may be paid licensing fees for use of their indices or index names. Entities will not be obligated to license their indices to BFA and its Affiliates, and BFA and its Affiliates will not be assured that the terms of any index licensing agreement with the Entities will be as favorable as those terms offered to other index licensees.

The Fund’s activities may be limited because of regulatory restrictions applicable to one or more Affiliates or Entities, and/or their internal policies designed to comply with such restrictions. In addition, the Fund may invest in securities of companies with which an Affiliate or an Entity has or is trying to develop investment banking relationships or in which an Affiliate or an Entity has significant debt or equity investments. The Fund also may invest in securities of companies for which an Affiliate or an Entity provides or may some day provide research coverage. An Affiliate or an Entity may have business relationships with and purchase or distribute or sell services or products from or to distributors, consultants or others who recommend the Fund or who engage in transactions with or for the Fund, and may receive compensation for such services. The Fund may also make brokerage and other payments to Affiliates or Entities in connection with the Fund’s portfolio investment transactions.

Pursuant to a securities lending program approved by the Board, the Fund has retained an Affiliate of BFA to serve as the securities lending agent for the Fund to the extent that the Fund participates in the securities lending program. For these services, the

lending agent may receive a fee from the Fund, including a fee based on the returns earned on the Fund’s investment of the cash received as collateral for any loaned securities. In addition, one or more Affiliates may be among the entities to which the Fund may lend its portfolio securities under the securities lending program.

The activities of BFA, the Affiliates or Entities may give rise to other conflicts of interest that could disadvantage the Fund and its shareholders. BFA has adopted policies and procedures designed to address these potential conflicts of interest. See the Fund’s SAI for further information.

Shareholder Information

Additional shareholder information, including how to buy and sell shares of the Fund, is available free of charge by calling toll-free: 1-800-iShares (1-800-474-2737) or visiting our website at www.iShares.com.

Buying and Selling Shares. Shares of the Fund may be acquired or redeemed directly from the Fund only in Creation Units or multiples thereof, as discussed in the Creations and Redemptions section of this Prospectus. Only an Authorized Participant (as defined in the Creations and Redemptions section) may engage in creation or redemption transactions directly with the Fund. Once created, shares of the Fund generally trade in the secondary market in amounts less than a Creation Unit.

Shares of the Fund are listed on a national securities exchange for trading during the trading day. Shares can be bought and sold throughout the trading day like shares of other publicly-traded companies. The Trust does not impose any minimum investment for shares of the Fund purchased on an exchange. The Fund’s shares trade under the trading symbol “FCHI.”

Buying or selling Fund shares on an exchange involves two types of costs that may apply to all securities transactions. When buying or selling shares of the Fund through a broker, you will likely incur a brokerage commission or other charges determined by your broker. The commission is frequently a fixed amount and may be a significant proportional cost for investors seeking to buy or sell small amounts of shares. In addition, you may incur the cost of the “spread” – that is, any difference between the bid price and the ask price. The spread varies over time for shares of the Fund based on its trading volume and market liquidity, and is generally lower if the Fund has a lot of trading volume and market liquidity, and higher if the Fund has little trading volume and market liquidity.

The Board has adopted a policy of not monitoring for frequent purchases and redemptions of Fund shares (“frequent trading”) that appear to attempt to take advantage of a potential arbitrage opportunity presented by a lag between a change in the value of the Fund’s portfolio securities after the close of the primary markets for the Fund’s portfolio securities and the reflection of that change in the Fund’s NAV (“market timing”), because the Fund generally sells and redeems its shares directly through transactions that are in-kind and/or for cash, subject to the conditions described below under Creations and Redemptions. The Board has not adopted a policy of monitoring for other frequent trading activity because shares of the Fund are listed for trading on a national securities exchange.

The national securities exchange on which the Fund’s shares are listed is open for trading Monday through Friday and is closed on weekends and the following holidays: New Year’s Day, Martin Luther King, Jr. Day, Presidents’ Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day. The Fund’s primary listing exchange is NASDAQ.

Section 12(d)(1) of the 1940 Act restricts investments by investment companies in the securities of other investment companies. Registered investment companies are permitted to invest in the Fund beyond the limits set forth in Section 12(d)(1), subject to certain terms and conditions set forth in SEC rules or in an SEC exemptive order issued to the Trust. In order for a registered investment company to invest in shares of the Fund beyond the limitations of Section 12(d)(1) pursuant to the exemptive relief obtained by the Trust, the registered investment company must enter into an agreement with the Trust.

Book Entry. Shares of the Fund are held in book-entry form, which means that no stock certificates are issued. The Depository Trust Company (“DTC”) or its nominee is the record owner of all outstanding shares of the Fund and is recognized as the owner of all shares for all purposes.

Investors owning shares of the Fund are beneficial owners as shown on the records of DTC or its participants. DTC serves as the securities depository for shares of the Fund. DTC participants include securities brokers and dealers, banks, trust companies, clearing corporations and other institutions that directly or indirectly maintain a custodial relationship with DTC. As a beneficial owner of shares, you are not entitled to receive physical delivery of stock certificates or to have shares registered in your name, and you are not considered a registered owner of shares. Therefore, to exercise any right as an owner of shares, you must rely upon the procedures of DTC and its participants. These procedures are the same as those that apply to any other securities that you hold in book-entry or “street name” form.

Share Prices. The trading prices of the Fund’s shares in the secondary market generally differ from the Fund’s daily NAV and are affected by market forces such as supply and demand, economic conditions and other factors. Information regarding the intraday value of shares of the Fund, also known as the “indicative optimized portfolio value” (“IOPV”), is disseminated every 15 seconds throughout the trading day by the national securities exchange on which the Fund’s shares are listed or by market data vendors or other information providers. The IOPV is based on the current market value of the securities and/or cash required to be deposited in exchange for a Creation Unit. The IOPV does not necessarily reflect the precise composition of the current portfolio of securities held by the Fund at a particular point in time or the best possible valuation of the current portfolio. Therefore, the IOPV should not be viewed as a “real-time” update of the Fund’s NAV, which is computed only once a day. The IOPV is generally determined by using both current market quotations and/or price quotations obtained from broker-dealers that may trade in the portfolio securities held by the Fund. The quotations of certain Fund holdings may not be updated during U.S. trading hours if such holdings do not trade in the United States. The Fund is not involved in, or responsible for, the calculation or dissemination of the IOPV and makes no representation or warranty as to its accuracy.

Determination of Net Asset Value. The NAV of the Fund normally is determined once daily Monday through Friday, generally as of the regularly scheduled close of business of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m., Eastern time) on each day that the NYSE is open for trading, based on prices at the time of closing provided that (a) any Fund assets or liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers (as detailed below) and (b) U.S. fixed income assets may be valued as of the announced closing time for trading in fixed income instruments in a particular market or exchange. The NAV of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets held by the Fund, and its liabilities, are determined pursuant to valuation policies and procedures approved by the Board. The Fund’s assets and liabilities are valued primarily on the basis of market quotations.

Equity investments are valued at market value, which is generally determined using the last reported official closing price or last trading price on the exchange or market on which the security is primarily traded at the time of valuation.

The Fund invests in foreign securities. Foreign currency exchange rates are generally determined as of 4:00 p.m., London time. Foreign securities owned by the Fund may trade on weekends or other days when the Fund does not price its shares. As a result, the Fund’s NAV may change on days when Authorized Participants will not be able to purchase or redeem Fund shares.

Generally, trading in foreign securities, U.S. government securities, money market instruments and certain fixed-income securities is substantially completed each day at various times prior to the close of business on the NYSE. The values of such securities used in computing the NAV of the Fund are determined as of such times.

When market quotations are not readily available or are believed by BFA to be unreliable, the Fund’s investments are valued at fair value. Fair value determinations are made by BFA in accordance with policies and procedures approved by the Fund’s Board. BFA may conclude that a market quotation is not readily available or is unreliable if a security or other asset or liability does not have a price source due to its lack of liquidity, if a market quotation differs significantly from recent price quotations or otherwise no longer appears to reflect fair value, where the security or other asset or liability is thinly traded, or where there is a significant event subsequent to the most recent market quotation. A “significant event” is an event that, in the judgment of BFA, is likely to cause a material change to the closing market price of the asset or liability held by the Fund. Foreign securities whose values are affected by volatility that occurs in U.S. markets on a trading day after the close of foreign securities markets may be fair valued.

Fair value represents a good faith approximation of the value of an asset or liability. The fair value of an asset or liability held by the Fund is the amount the Fund might reasonably expect to receive from the current sale of that asset or the cost to extinguish that liability in an arm’s-length transaction. Valuing the Fund’s investments

using fair value pricing will result in prices that may differ from current market valuations and that may not be the price at which those investments could have been sold during the period in which the particular fair values were used. Use of fair value prices and certain current market valuations could result in a difference between the prices used to calculate the Fund’s NAV and the prices used by the Underlying Index, which, in turn, could result in a difference between the Fund’s performance and the performance of the Underlying Index.

The value of assets or liabilities denominated in non-U.S. currencies will be converted into U.S. dollars using exchange rates deemed appropriate by BFA as investment adviser. Use of a rate different from the rate used by the Index Provider may adversely affect the Fund’s ability to track the Underlying Index.

Dividends and Distributions

General Policies. Dividends from net investment income, if any, generally are declared and paid semi-annually by the Fund. Distributions of net realized securities gains, if any, generally are declared and paid once a year, but the Trust may make distributions on a more frequent basis for the Fund. The Trust reserves the right to declare special distributions if, in its reasonable discretion, such action is necessary or advisable to preserve its status as a regulated investment company (“RIC”) or to avoid imposition of income or excise taxes on undistributed income or realized gains.

Dividends and other distributions on shares of the Fund are distributed on a pro rata basis to beneficial owners of such shares. Dividend payments are made through DTC participants and indirect participants to beneficial owners then of record with proceeds received from the Fund.

Dividend Reinvestment Service. No dividend reinvestment service is provided by the Trust. Broker-dealers may make available the DTC book-entry Dividend Reinvestment Service for use by beneficial owners of the Fund for reinvestment of their dividend distributions. Beneficial owners should contact their broker to determine the availability and costs of the service and the details of participation therein. Brokers may require beneficial owners to adhere to specific procedures and timetables. If this service is available and used, dividend distributions of both income and realized gains will be automatically reinvested in additional whole shares of the Fund purchased in the secondary market.

Taxes. As with any investment, you should consider how your investment in shares of the Fund will be taxed. The tax information in this Prospectus is provided as general information, based on current law. You should consult your own tax professional about the tax consequences of an investment in shares of the Fund.

Unless your investment in Fund shares is made through a tax-exempt entity or tax-deferred retirement account, such as an IRA, you need to be aware of the possible tax consequences when the Fund makes distributions or you sell Fund shares.

Taxes on Distributions. Distributions from the Fund’s net investment income (other than qualified dividend income), including distributions of income from securities lending and distributions out of the Fund’s net short-term capital gains, if any, are taxable to you as ordinary income. Distributions by the Fund of net long-term capital gains in excess of net short-term capital losses (capital gain dividends) are taxable to

you as long-term capital gains, generally at a 15% tax rate (0% at certain income levels), regardless of how long you have held the Fund’s shares. Distributions by the Fund that qualify as qualified dividend income are taxable to you at long-term capital gain rates for taxable years beginning on or before December 31, 2012. The 15% and 0% tax rates expire for taxable years beginning after December 31, 2012. Maximum long-term capital gain income tax rates are scheduled to rise to 20% in 2013. Beginning in 2013, a 3.8% U.S. federal Medicare contribution tax will be imposed on “net investment income,” including interest, dividends, and capital gains, of U.S. individuals with income exceeding $200,000 (or $250,000 if married and filing jointly), and of estates and trusts.

Dividends will be qualified dividend income to you if they are attributable to qualified dividend income received by the Fund. Generally, qualified dividend income includes dividend income from taxable U.S. corporations and qualified non-U.S. corporations, provided that the Fund satisfies certain holding period requirements in respect of the stock of such corporations and has not hedged its position in the stock in certain ways. Substitute dividends received by the Fund with respect to dividends paid on securities lent out will not be qualified dividend income. For this purpose, a qualified non-U.S. corporation means any non-U.S. corporation that is eligible for benefits under a comprehensive income tax treaty with the United States, which includes an exchange of information program or if the stock with respect to which the dividend was paid is readily tradable on an established United States securities market. The term excludes a corporation that is a passive foreign investment company. Under current Internal Revenue Service (“IRS”) guidance, the United States has an appropriate comprehensive income tax treaty with China but not with Hong Kong, which is treated as a separate jurisdiction for United States tax purposes.

Dividends received by the Fund from a real estate investment trust (“REIT”) or another RIC generally are qualified dividend income only to the extent the dividend distributions are made out of qualified dividend income received by such REIT or RIC. It is expected that dividends received by the Fund from a REIT and distributed to a shareholder generally will be taxable to the shareholder as ordinary income.

For a dividend to be treated as qualified dividend income, the dividend must be received with respect to a share of stock held without being hedged by the Fund, and with respect to a share of the Fund held without being hedged by you, for 61 days during the 121-day period beginning at the date which is 60 days before the date on which such share becomes ex-dividend with respect to such dividend or, in the case of certain preferred stock, 91 days during the 181-day period beginning 90 days before such date.

If your Fund shares are loaned out pursuant to a securities lending arrangement, you may lose the ability to use foreign tax credits passed through by the Fund or to treat Fund dividends paid while the shares are held by the borrower as qualified dividend income.

In general, your distributions are subject to U.S. federal income tax for the year when they are paid. Certain distributions paid in January, however, may be treated as paid on December 31 of the prior year.

If the Fund’s distributions exceed current and accumulated earnings and profits, all or a portion of the distributions made in the taxable year may be recharacterized as a return of capital to shareholders. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and result in a higher capital gain or lower capital loss when those shares on which the distribution was received are sold. Once a shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain, if the shareholder holds shares of the Fund as capital assets.

If you are neither a resident nor a citizen of the United States or if you are a non-U.S. entity, the Fund’s ordinary income dividends (which include distributions of net short-term capital gains) will generally be subject to a 30% U.S. withholding tax, unless a lower treaty rate applies, provided that withholding tax will generally not apply to any gain or income realized by a non-U.S. shareholder in respect of any distributions of long-term capital gains or upon the sale or other disposition of shares of the Fund.

A 30% withholding tax will be imposed on dividends paid after December 31, 2013, and redemption proceeds paid after December 31, 2014, to (i) foreign financial institutions including non-U.S. investment funds unless they agree to collect and disclose to the IRS information regarding their direct and indirect U.S. account holders and (ii) certain other foreign entities, unless they certify certain information regarding their direct and indirect U.S. owners. To avoid withholding, foreign financial institutions will need to enter into agreements with the IRS that state that they will provide the IRS information, including the name, address and taxpayer identification number of direct and indirect U.S. account holders, comply with due diligence procedures with respect to the identification of U.S. accounts, report to the IRS certain information with respect to U.S. accounts maintained, agree to withhold tax on certain payments made to non-compliant foreign financial institutions or to account holders who fail to provide the required information, and determine certain other information as to their account holders. Other foreign entities will need to provide the name, address, and taxpayer identification number of each substantial U.S. owner or certifications of no substantial U.S. ownership unless certain exceptions apply.

Dividends, interest and capital gains earned by the Fund with respect to non-U.S. securities may give rise to withholding and other taxes imposed by non-U.S. countries. Tax conventions between certain countries and the United States may reduce or eliminate such taxes. If more than 50% of the total assets of the Fund at the close of a year consists of non-U.S. stocks or securities, the Fund may “pass through” to you certain non-U.S. income taxes (including withholding taxes) paid by the Fund. This means that you would be considered to have received as an additional dividend your share of such non-U.S. taxes, but you may be entitled to either a corresponding tax deduction in calculating your taxable income, or, subject to certain limitations, a credit in calculating your U.S. federal income tax.

For purposes of foreign tax credits for U.S. shareholders of the Fund, foreign capital gains taxes may not produce associated foreign source income, thereby limiting a U.S. person’s ability to use such credits.

If you are a resident or a citizen of the United States, by law, back-up withholding will apply to your distributions and proceeds if you have not provided a taxpayer identification number or social security number and made other required certifications.

Taxes When Shares are Sold. Currently, any capital gain or loss realized upon a sale of Fund shares is generally treated as a long-term gain or loss if the shares have been held for more than one year. Any capital gain or loss realized upon a sale of Fund shares held for one year or less is generally treated as short-term gain or loss, except that any capital loss on the sale of shares held for six months or less is treated as long-term capital loss to the extent that capital gain dividends were paid with respect to such shares. Beginning in 2013, any such capital gains, including from sales of Fund shares or from capital gain dividends, will be included in “net investment income” for purposes of the 3.8% U.S. federal Medicare contribution tax mentioned above.

The foregoing discussion summarizes some of the consequences under current U.S. federal tax law of an investment in the Fund. It is not a substitute for personal tax advice. You may also be subject to state and local taxation on Fund distributions and sales of shares. Consult your personal tax adviser about the potential tax consequences of an investment in shares of the Fund under all applicable tax laws.

Chinese Tax Disclosure. Although the PRC’s enactment of the Enterprise Income Tax Law, effective January 1, 2008, provided a 10% withholding tax upon non-residents with respect to capital gains, significant uncertainties remain. Such uncertainties may result in capital gains imposed upon the Fund relative to companies headquartered, managed or listed in China. While the application and enforcement of this law to the Fund remains subject to clarification, to the extent that such taxes are imposed on any capital gains of the Fund relative to companies headquartered, managed or listed in China, the Fund’s NAV or returns may be adversely impacted.

Creations and Redemptions. Prior to trading in the secondary market, shares of the Fund are “created” at NAV by market makers, large investors and institutions only in block-size Creation Units of 100,000 shares or multiples thereof. Each “creator” or “Authorized Participant” enters into an authorized participant agreement with the Fund’s distributor, SEI Investments Distribution Co. (the “Distributor”). Only an Authorized Participant may create or redeem Creation Units directly with the Fund. A creation transaction, which is subject to acceptance by the transfer agent, generally takes place when an Authorized Participant deposits into the Fund a designated portfolio of securities and a specified amount of cash approximating the holdings of the Fund in exchange for a specified number of Creation Units. To the extent practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund.

Similarly, shares can be redeemed only in Creation Units, generally for a designated portfolio of securities and a specified amount of cash held by the Fund (“Fund Securities”). Except when aggregated in Creation Units, shares are not redeemable by the Fund. The prices at which creations and redemptions occur are based on the next calculation of NAV after an order is received in a form described in the authorized participant agreement.

The Fund intends to comply with the U.S. federal securities laws in accepting securities for deposit and satisfying redemptions with redemption securities by, among other means, assuring that any securities accepted for deposit and any securities used to satisfy redemption requests will be sold in transactions that would be exempt from registration under the Securities Act of 1933, as amended (the “1933 Act”). Further,

an Authorized Participant that is not a “qualified institutional buyer,” as such term is defined under Rule 144A of the 1933 Act, will not be able to receive Fund Securities that are restricted securities eligible for resale under Rule 144A.

Creations and redemptions must be made through a firm that is either a member of the Continuous Net Settlement System of the National Securities Clearing Corporation or a DTC participant and has executed an agreement with the Distributor with respect to creations and redemptions of Creation Unit aggregations. Information about the procedures regarding creation and redemption of Creation Units (including the cut-off times for receipt of creation and redemption orders) is included in the Fund’s SAI.

Because new shares may be created and issued on an ongoing basis, at any point during the life of the Fund a “distribution,” as such term is used in the 1933 Act, may be occurring. Broker-dealers and other persons are cautioned that some activities on their part may, depending on the circumstances, result in their being deemed participants in a distribution in a manner that could render them statutory underwriters and subject to the prospectus delivery and liability provisions of the 1933 Act. Any determination of whether one is an underwriter must take into account all the relevant facts and circumstances of each particular case.

Broker-dealers should also note that dealers who are not “underwriters” but are participating in a distribution (as contrasted to ordinary secondary transactions), and thus dealing with shares that are part of an “unsold allotment” within the meaning of Section 4(3)(C) of the 1933 Act, would be unable to take advantage of the prospectus delivery exemption provided by Section 4(3) of the 1933 Act. For delivery of prospectuses to exchange members, the prospectus delivery mechanism of Rule 153 under the 1933 Act is available only with respect to transactions on a national securities exchange.

Costs Associated with Creations and Redemptions. Authorized Participants are charged standard creation and redemption transaction fees to offset transfer and other transaction costs associated with the issuance and redemption of Creation Units. The standard creation and redemption transaction fees are set forth in the table below. The standard creation transaction fee is charged to the Authorized Participant on the day such Authorized Participant creates a Creation Unit, and is the same regardless of the number of Creation Units purchased by the Authorized Participant on the applicable business day. Similarly, the standard redemption transaction fee is charged to the Authorized Participant on the day such Authorized Participant redeems a Creation Unit, and is the same regardless of the number of Creation Units redeemed by the Authorized Participant on the applicable business day. Creations and redemptions for cash (when cash creations and redemptions (in whole or in part) are available or specified) are also subject to an additional charge (up to the maximum amounts shown in the table below). This charge is intended to compensate for brokerage, tax, foreign exchange, execution, market impact and other costs and expenses related to cash transactions. Investors who use the services of a broker or other financial intermediary may pay fees for such services.

The following table shows, as of September 30, 2011, the approximate value of one Creation Unit, standard fees and maximum additional charges for creations and redemptions (as described above):

Householding. Householding is an option available to certain Fund investors. Householding is a method of delivery, based on the preference of the individual investor, in which a single copy of certain shareholder documents can be delivered to investors who share the same address, even if their accounts are registered under different names. Please contact your broker-dealer if you are interested in enrolling in householding and receiving a single copy of prospectuses and other shareholder documents, or if you are currently enrolled in householding and wish to change your householding status.

Distribution

The Distributor distributes Creation Units for the Fund on an agency basis. The Distributor does not maintain a secondary market in shares of the Fund. The Distributor has no role in determining the policies of the Fund or the securities that are purchased or sold by the Fund. The Distributor’s principal address is One Freedom Valley Drive, Oaks, PA 19456.

In addition, BFA or its Affiliates make payments to broker-dealers, banks or other financial intermediaries (together, “intermediaries”) related to marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems, or their making shares of the Fund and certain other iShares funds available to their customers. Such payments, which may be significant to the intermediary, are not made by the Fund. Rather, such payments are made by BFA or its Affiliates from their own resources, which come directly or indirectly in part from fees paid by the iShares funds complex. Payments of this type are sometimes referred to as revenue-sharing payments. A financial intermediary may make decisions about which investment options it recommends or makes available, or the level of services provided, to its customers based on the revenue-sharing payments it is eligible to receive. Therefore, such payments to an intermediary create conflicts of interest between the intermediary and its customers and may cause the intermediary to recommend the Fund or other iShares funds over another investment. More information regarding these payments is contained in the Fund’s SAI. Please contact your salesperson or other investment professional for more information regarding any such payments his or her firm may receive from BFA or its Affiliates.

Financial Highlights

The financial highlights table is intended to help investors understand the Fund’s financial performance since inception. Certain information reflects financial results for a single share of the Fund. The total returns in the table represent the rate that an investor would have earned (or lost) on an investment in the Fund, assuming reinvestment of all dividends and distributions. This information has been audited by PricewaterhouseCoopers LLP, whose report is included, along with the Fund’s financial statements, in the Fund’s Annual Report (available upon request).

Supplemental Information

I. Premium/Discount Information

The table that follows presents information about the differences between the daily market price on secondary markets for shares of the Fund and the Fund’s NAV. NAV is the price at which the Fund issues and redeems shares. It is calculated in accordance with the standard formula for valuing mutual fund shares. The price used to calculate market returns (“Market Price”) of the Fund generally is determined using the midpoint between the highest bid and the lowest offer on the primary securities exchange on which shares of the Fund are listed for trading, as of the time that the Fund’s NAV is calculated. The Fund’s Market Price may be at, above or below its NAV. The NAV of the Fund will fluctuate with changes in the value of its portfolio holdings. The Market Price of the Fund will fluctuate in accordance with changes in its NAV, as well as market supply and demand.

Premiums or discounts are the differences (expressed as a percentage) between the NAV and Market Price of the Fund on a given day, generally at the time the NAV is calculated. A premium is the amount that the Fund is trading above the reported NAV, expressed as a percentage of the NAV. A discount is the amount that the Fund is trading below the reported NAV, expressed as a percentage of the NAV.

The following information shows the frequency of distributions of premiums and discounts for the Fund for each full calendar quarter of 2010 through September 30, 2011.

Each line in the table shows the number of trading days in which the Fund traded within the premium/discount range indicated. The number of trading days in each premium/discount range is also shown as a percentage of the total number of trading days in the period covered by the table. All data presented here represents past performance, which cannot be used to predict future results.

II. Total Return Information

The table that follows presents information about the total returns of the Fund and the Underlying Index as of the fiscal year ended July 31, 2011.

“Average Annual Total Returns” represent the average annual change in value of an investment over the periods indicated. “Cumulative Total Returns” represent the total change in value of an investment over the period indicated.

The Fund’s NAV is the value of one share of the Fund as calculated in accordance with the standard formula for valuing mutual fund shares. The NAV return is based on the NAV of the Fund and the market return is based on the Market Price of the Fund. Market Price is determined by using the midpoint between the highest bid and the lowest offer on the primary stock exchange on which shares of the Fund are listed for trading, as of the time that the Fund’s NAV is calculated. Since shares of the Fund did not trade in the secondary market until after the Fund’s inception, for the period from inception to the first day of secondary market trading in shares of the Fund, the NAV of the Fund is used as a proxy for the Market Price to calculate market returns. Market and NAV returns assume that dividends and capital gain distributions have been reinvested in the Fund at Market Price and NAV, respectively.

An index is a statistical composite that tracks a specified financial market or sector. Unlike the Fund, the Underlying Index does not actually hold a portfolio of securities and therefore does not incur the expenses incurred by the Fund. These expenses negatively impact the performance of the Fund. Also, market returns do not include brokerage commissions that may be payable on secondary market transactions. If brokerage commissions were included, market returns would be lower. The returns shown in the following table do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption or sale of Fund shares. The investment return and principal value of shares of the Fund will vary with changes in market conditions. Shares of the Fund may be worth more or less than their original cost when they are redeemed or sold in the market. The Fund’s past performance is no guarantee of future results.

Fund Overview

iSHARES® FTSE DEVELOPED SMALL CAP ex-NORTH AMERICA INDEX FUND

Ticker: IFSM Stock Exchange: NASDAQ

Investment Objective

The iShares FTSE Developed Small Cap ex-North America Index Fund (the “Fund”) seeks investment results that correspond generally to the price and yield performance, before fees and expenses, of the FTSE Developed Small Cap ex-North America Index (the “Underlying Index”).

Fees and Expenses

The following table describes the fees and expenses that you will incur if you own shares of the Fund. The investment advisory agreement between iShares Trust (the “Trust”) and BlackRock Fund Advisors (“BFA”) (the “Investment Advisory Agreement”) provides that BFA will pay all operating expenses of the Fund, except interest expenses, taxes, brokerage expenses, future distribution fees or expenses, and extraordinary expenses.

You may also incur usual and customary brokerage commissions when buying or selling shares of the Fund, which are not reflected in the example that follows:

Example. This Example is intended to help you compare the cost of owning shares of the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

1 Year

Portfolio Turnover. The Fund may pay transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 25% of the average value of its portfolio.

Principal Investment Strategies

The Underlying Index measures the stock performance of small-capitalization companies in developed countries outside North America, as defined by FTSE International Limited (“FTSE”). As of September 30, 2011, the Underlying Index was comprised of stocks of companies in the following countries or regions: Australia, Austria, Belgium, China, Denmark, Finland, France, Germany, Greece, Hong Kong, Indonesia, Ireland, Israel, Italy, Japan, Luxembourg, the Netherlands, New Zealand, Norway, Portugal, Singapore, South Africa, Spain, Sweden, Switzerland, Taiwan and the United Kingdom. Component companies include consumer services, financial, and industrial companies.

BFA uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to “beat” the index it tracks and does not seek temporary defensive positions when markets decline or appear overvalued.

Indexing may eliminate the chance that the Fund will substantially outperform the Underlying Index but also may reduce some of the risks of active management, such as poor security selection. Indexing seeks to achieve lower costs and better after-tax performance by keeping portfolio turnover low in comparison to actively managed investment companies.

BFA uses a representative sampling indexing strategy to manage the Fund. “Representative sampling” is an indexing strategy that involves investing in a representative sample of securities that collectively has an investment profile similar to the Underlying Index. The securities selected are expected to have, in the aggregate, investment characteristics (based on factors such as market capitalization and industry weightings), fundamental characteristics (such as return variability and yield) and liquidity measures similar to those of the Underlying Index. The Fund may or may not hold all of the securities in the Underlying Index.

The Fund generally invests at least 90% of its assets in securities of the Underlying Index and in depositary receipts representing securities of the Underlying Index. The Fund may invest the remainder of its assets in securities not included in the Underlying Index, but which BFA believes will help the Fund track the Underlying Index and in other investments including futures contracts, options on futures contracts, options and swaps as well as cash and cash equivalents, including shares of money market funds advised by BFA or its affiliates.

The Fund may lend securities representing up to one-third of the

S-4

value of the Fund’s total assets (including the value of the collateral received).

The Underlying Index is sponsored by an organization (the “Index Provider”) that is independent of the Fund and BFA. The Index Provider determines the composition and relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index. The Fund’s Index Provider is FTSE.

Industry Concentration Policy. The Fund will concentrate its investments (i.e., hold 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. For purposes of this limitation, securities of the U.S. government (including its agencies and instrumentalities) and repurchase agreements collateralized by U.S. government securities are not considered to be issued by members of any industry.

Summary of Principal Risks

As with any investment, you could lose all or part of your investment in the Fund, and the Fund’s performance could trail that of other investments. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund’s NAV, trading price, yield, total return and ability to meet its investment objective.

Asset Class Risk. Securities in the Underlying Index or in the Fund’s portfolio may underperform in comparison to the general securities markets or other asset classes.

Concentration Risk. To the extent that the Fund’s investments are concentrated in a particular issuer, region, country, market, industry or asset class, the Fund may be susceptible to loss due to adverse occurrences affecting that issuer, region, country, market, industry or asset class.

Consumer Services Sector Risk. The consumer services sector may be affected by changes in the domestic and international economy, exchange rates, competition, consumers’ disposable income and consumer preferences.

Currency Risk. Because the Fund’s NAV is determined in U.S. dollars, the Fund’s NAV could decline if the currency of a non-U.S. market in which the Fund invests depreciates against the U.S. dollar.

Equity Securities Risk. Equity securities are subject to changes in value and their values may be more volatile than other asset classes.

Financial Sector Risk. Performance of companies in the financial sector may be adversely impacted by many factors, including, among others, government regulations, economic conditions, credit rating downgrades, changes in interest rates, and decreased liquidity in credit markets. This sector has experienced significant losses in the recent past, and the impact of more stringent capital requirements and of recent or future regulation on any individual financial company or on the sector as a whole cannot be predicted.

Geographic Risk. A natural or other disaster could occur in a geographic region in which the Fund invests, which could affect the economy or particular business operations of companies in the specific geographic region, causing an adverse impact on the Fund’s investments in the affected region.

Industrials Sector Risk. The industrials sector is affected by changes in the supply and demand for products and services, product obsolescence, claims for environmental damage or product liability and general economic conditions, among other factors.

Issuer Risk. Fund performance depends on the performance of individual securities to which the Fund has exposure. Changes to the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA’s investment management strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares, losses from trading in secondary markets, periods of high volatility and disruption in the creation/redemption process of the Fund. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV.

Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers are subject to the risks associated with investing in those non-U.S. markets, such as heightened risks of inflation or nationalization. The Fund may lose money due to political, economic and geographic events affecting a non-U.S. issuer or market. The Fund is specifically exposed to Asian Economic Risk and European Economic Risk.

Passive Investment Risk. The Fund is not actively managed and BFA does not attempt to take defensive positions under any market conditions, including declining markets.

Reliance on Trading Partners Risk. The Fund invests in countries whose economies are heavily dependent upon trading with key partners. Any reduction in this trading may have an adverse impact on the Fund’s investments. Through its trading partners, the Fund is particularly exposed to U.S. Trading Partner Risk.

Risk of Investing in Japan. The Japanese economy may be subject to considerable degrees of economic, political and social instability, which could have a negative impact on Japanese securities.

Securities Lending Risk. The Fund may engage in securities lending. Securities lending involves the risk that the Fund may lose money because the borrower of the Fund’s loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Security Risk. Some countries and regions in which the Fund invests have experienced security concerns. Incidents involving a country’s or region’s security may cause uncertainty in these markets and may adversely affect their economies and the Fund’s investments.

Small-Capitalization Companies Risk. The Fund invests in the securities of small-capitalization companies. Compared to mid- and large-capitalization companies, small-capitalization companies may be less stable and more susceptible to adverse developments and their securities may be more volatile and less liquid.

Tracking Error Risk. The performance of the Fund may diverge from that of the Underlying Index. Because the Fund employs a representative sampling strategy, the Fund may experience tracking error to a greater extent than a fund that seeks to replicate an index.

Valuation Risk. The value of the securities in the Fund’s portfolio may change on days when shareholders will not be able to purchase or sell the Fund’s shares.

Performance Information

The bar chart and table that follow show how the Fund has performed on a calendar year basis and provide an indication of the risks of investing in the Fund. Both assume that all dividends and distributions have been reinvested in the Fund. Past performance (before and after taxes) does not necessarily indicate how the Fund will perform in the future. Supplemental information about the Fund’s performance is shown under the heading Total Return Information in the Supplemental Information section of the Prospectus.

Year by Year Returns1 (Years Ended December 31)


1 The Fund’s total return for the nine months ended September 30, 2011 was -18.13%.

The best calendar quarter return during the periods shown above was 33.62% in the 2nd quarter of 2009; the worst was
-24.60% in the 3rd quarter of 2008.

1 After-tax returns in the table above are calculated using the historical highest individual U.S. federal marginal income tax rates and do not reflect the impact of state or local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown, and after-tax returns shown are not relevant to tax-exempt investors or investors who hold shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts (“IRAs”). Fund returns after taxes on distributions and sale of Fund shares are calculated assuming that an investor has sufficient capital gains of the same character from other investments to offset any capital losses from the sale of Fund shares. As a result, Fund returns after taxes on distributions and sale of Fund shares may exceed Fund returns before taxes and/or returns after taxes on distributions.

Management

Investment Adviser. BlackRock Fund Advisors.

Portfolio Managers. Rene Casis, Diane Hsiung and Greg Savage (the “Portfolio Managers”) are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager supervises a portfolio management team. Mr. Casis, Ms. Hsiung and Mr. Savage have been Portfolio Managers of the Fund since 2010, 2008 and 2008, respectively.

Purchase and Sale of Fund Shares

The Fund is an exchange-traded fund (commonly referred to as an “ETF”). Individual Fund shares may only be purchased and sold on a national securities exchange through a broker-dealer. The price of Fund shares is based on market price, and because ETF shares trade at market prices rather than NAV, shares may trade at a price greater than NAV (a premium) or less than NAV (a discount). The Fund will only issue or redeem shares that have been aggregated into blocks of 200,000 shares or multiples thereof (“Creation Units”) to authorized participants who have entered into agreements with the Fund’s distributor. The Fund generally will issue or redeem Creation Units in return for a designated portfolio of securities (and an amount of cash) that the Fund specifies each day.

Tax Information

The Fund intends to make distributions that may be taxable to you as ordinary income or capital gains, unless you are investing through a tax-deferred arrangement such as a 401(k) plan or an IRA.

Payments to Broker-Dealers and other Financial Intermediaries

If you purchase shares of the Fund through a broker-dealer or other financial intermediary (such as a bank), BFA or other related companies may pay the intermediary for marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems or other services related to the sale or promotion of the Fund. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.

More Information About the Fund

This Prospectus contains important information about investing in the Fund. Please read this Prospectus carefully before you make any investment decisions. Additional information regarding the Fund is available at www.iShares.com.

BFA is the investment adviser to the Fund. Shares of the Fund are listed for trading on The NASDAQ Stock Market (“NASDAQ”). The market price for a share of the Fund may be different from the Fund’s most recent NAV.

ETFs are funds that trade like other publicly-traded securities. The Fund is designed to track an index. Similar to shares of an index mutual fund, each share of the Fund represents a partial ownership in an underlying portfolio of securities intended to track a market index. Unlike shares of a mutual fund, which can be bought and redeemed from the issuing fund by all shareholders at a price based on NAV, shares of the Fund may be purchased or redeemed directly from the Fund at NAV solely by authorized participants. Also unlike shares of a mutual fund, shares of the Fund are listed on a national securities exchange and trade in the secondary market at market prices that change throughout the day.

The Fund invests in a particular segment of the securities markets and seeks to track the performance of a securities index that generally is not representative of the market as a whole. The Fund is designed to be used as part of broader asset allocation strategies. Accordingly, an investment in the Fund should not constitute a complete investment program.

An index is a theoretical financial calculation while the Fund is an actual investment portfolio. The performance of the Fund and the Underlying Index may vary due to transaction costs, non-U.S. currency valuations, asset valuations, corporate actions (such as mergers and spin-offs), timing variances and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions (such as diversification requirements) that apply to the Fund but not to the Underlying Index or to the use of representative sampling. “Tracking error” is the difference between the performance (return) of the Fund’s portfolio and that of the Underlying Index. BFA expects that, over time, the Fund’s tracking error will not exceed 5%. Because the Fund uses a representative sampling indexing strategy, it can be expected to have a larger tracking error than if it used a replication indexing strategy. “Replication” is an indexing strategy in which a fund invests in substantially all of the securities in its underlying index in approximately the same proportions as in the underlying index.

An investment in the Fund is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, BFA or any of its affiliates.

The Fund’s investment objective and the Underlying Index may be changed without shareholder approval.

A Further Discussion of Principal Risks

The Fund is subject to various risks, including the principal risks noted below, any of which may adversely affect the Fund’s NAV, trading price, yield, total return and ability to meet its investment objective. You could lose all or part of your investment in the Fund, and the Fund could underperform other investments.

Asian Economic Risk. Certain Asian economies have experienced over-extension of credit, currency devaluations and restrictions, high unemployment, high inflation, decreased exports and economic recessions. Economic events in any one Asian country may have a significant economic effect on the entire Asian region, as well as on major trading partners outside Asia, and any adverse event in the Asian markets may have a significant adverse effect on some or all of the economies in which the Fund invests.

Asset Class Risk. The securities in the Underlying Index or in the Fund’s portfolio may underperform the returns of other securities or indexes that track other countries, groups of countries, regions, industries, groups of industries, markets, asset classes or sectors. Various types of securities or indexes tend to experience cycles of outperformance and underperformance in comparison to the general securities markets.

Concentration Risk. To the extent that the Fund’s portfolio reflects the Underlying Index’s concentration in the securities of a particular issuer or issuers in a particular country, group of countries, region, market, industry, group of industries, sector or asset class, the Fund may be adversely affected by the performance of those securities, may be subject to increased price volatility and may be more susceptible to adverse economic, market, political or regulatory occurrences affecting that issuer, country, group of countries, region, market, industry, group of industries, sector or asset class.

Consumer Services Sector Risk. The success of consumer product manufacturers and retailers (including food and drug retailers, general retailers, media, and travel and leisure) is tied closely to the performance of the domestic and international economy, interest rates, exchange rates, competition and consumer confidence. The consumer services sector depends heavily on disposable household income and consumer spending. Companies in the consumer services sector may be subject to severe competition, which may also have an adverse impact on their profitability. Changes in demographics and consumer preferences may affect the success of consumer products.

Currency Risk. Because the Fund’s NAV is determined on the basis of the U.S. dollar, investors may lose money if the currency of a non-U.S. market in which the Fund invests depreciates against the U.S. dollar, even if the local currency value of the Fund’s holdings in that market increases.

Equity Securities Risk. The Fund invests in equity securities, which are subject to changes in value that may be attributable to market perception of a particular issuer or to general stock market fluctuations that affect all issuers. Investments in equity securities may be more volatile than investments in other asset classes.

European Economic Risk. The Economic and Monetary Union of the European Union (the “EU”) requires member countries to comply with restrictions on inflation rates, deficits, interest rates, debt levels and fiscal and monetary controls, each of which may significantly affect every country in Europe. Decreasing imports or exports, changes in governmental or EU regulations on trade, changes in the exchange rate of the euro, the default or threat of default by an EU member country on its sovereign debt, and/or an economic recession in an EU member country may have a significant adverse effect on the economies of EU member countries and their trading partners. The European financial markets have recently experienced volatility and have been adversely affected by concerns about economic downturns, credit rating downgrades, rising government debt levels and possible default on or restructuring of government debt in several European countries, including Greece, Ireland, Italy, Portugal and Spain. A default or debt restructuring by any European country would adversely impact holders of that country’s debt, and sellers of credit default swaps linked to that country’s creditworthiness, which may be located in countries other than those listed in the previous sentence. These events have adversely affected the value and exchange rate of the euro and may continue to significantly affect the economies of every country in Europe, including EU member countries that do not use the euro and non-EU member countries.

Financial Sector Risk. Companies in the financial sector of an economy are often subject to governmental regulation and, recently, government intervention and the potential for additional regulation, which may adversely affect the scope of their activities, the prices they can charge and the amount of capital they must maintain. Governmental regulation may change frequently and may have significant adverse consequences for companies in the financial sector, including effects not intended by such regulation. The impact of recent or future regulation in various countries on any individual financial company or on the sector as a whole cannot be predicted. Certain risks may impact the value of investments in the financial sector more severely than investments outside this sector, including the risks associated with companies that operate with substantial financial leverage. Companies in the financial sector may also be adversely affected by increases in interest rates and loan losses, decreases in the availability of money or asset valuations, credit rating downgrades and adverse conditions in other related markets. Over the past few years, the deterioration of the credit markets has impacted a broad range of mortgage, asset-backed, auction rate, sovereign debt and other markets, including U.S. and non-U.S. credit and interbank money markets, thereby affecting a wide range of financial institutions and markets. This situation has created instability in the financial markets and caused certain financial companies to incur large losses. Some financial companies have experienced declines in the valuations of their assets, taken actions to raise capital (such as the issuance of debt or equity securities), or even ceased operations. Some financial companies have borrowed significant amounts of capital from governments and may face future government-imposed restrictions on their businesses or increased government intervention. These actions have caused the securities of many financial companies to decline in value. Insurance companies, in particular, may be subject to severe price competition, which may have an adverse impact on their profitability.

Geographic Risk. Some markets in which the Fund invests are located in parts of the world that have historically been prone to natural disasters, such as earthquakes, volcanoes, droughts, floods, hurricanes and tsunamis, and are economically sensitive to environmental events. Any natural or other disaster could have a significant adverse impact on the economies of these geographic areas, causing an adverse impact on the Fund’s investments in the affected region.

Industrials Sector Risk. The stock prices of companies in the industrials sector are affected by supply and demand, both for their specific product or service and for industrials sector products in general. The products of manufacturing companies may face obsolescence due to rapid technological developments and frequent new product introduction. Government regulations, world events, economic conditions and exchange rates affect the performance of companies in the industrials sector. Companies in the industrials sector may be adversely affected by liability for environmental damage, product liability claims and exchange rates. The industrials sector may also be adversely affected by changes or trends in commodity prices, which may be influenced by unpredictable factors.

Issuer Risk. The performance of the Fund depends on the performance of individual securities to which the Fund has exposure. Any issuer of these securities may perform poorly, causing the value of its securities to decline. Poor performance may be caused by poor management decisions, competitive pressures, changes in technology, expiration of patent protection, disruptions in supply, labor problems or shortages, corporate restructurings, fraudulent disclosures or other factors. Issuers may, in times of distress or at their own discretion, decide to reduce or eliminate dividends, which may also cause their stock prices to decline.

Management Risk. The Fund may not fully replicate the Underlying Index and may hold securities not included in the Underlying Index. As a result, the Fund is subject to the risk that BFA’s investment management strategy, the implementation of which is subject to a number of constraints, may not produce the intended results.

Market Risk. The Fund could lose money due to short-term market movements and over longer periods during market downturns. Securities may decline in value due to factors affecting securities markets generally or particular industries represented in the markets. The value of a security may decline due to general market conditions, economic trends or events that are not specifically related to the issuer of the security or to factors that affect a particular industry or industries. During a general downturn in the securities markets, multiple asset classes may be negatively affected.

Market Trading Risk

Absence of Active Market. Although shares of the Fund are listed for trading on one or more stock exchanges, there can be no assurance that an active trading market for such shares will develop or be maintained.

Risk of Secondary Listings. The Fund’s shares may be listed or traded on U.S. and non-U.S. stock exchanges other than the U.S. stock exchange where the Fund’s primary listing is maintained. There can be no assurance that the Fund’s shares will continue to trade on any such stock exchange or in any market or that the Fund’s shares will continue to meet the requirements for listing or trading on any exchange or in any

market. The Fund’s shares may be less actively traded in certain markets than others, and investors are subject to the execution and settlement risks and market standards of the market where they or their broker direct their trades for execution. Certain information available to investors who trade Fund shares on a U.S. stock exchange during regular U.S. market hours may not be available to investors who trade in other markets, which may result in secondary market prices in such markets being less efficient.

Secondary Market Trading Risk. Shares of the Fund may trade in the secondary market at times when the Fund does not accept orders to purchase or redeem shares. At such times, shares may trade in the secondary market with more significant premiums or discounts than might be experienced at times when the Fund accepts purchase and redemption orders.

Secondary market trading in Fund shares may be halted by a stock exchange because of market conditions or other reasons. In addition, trading in Fund shares on a stock exchange or in any market may be subject to trading halts caused by extraordinary market volatility pursuant to “circuit breaker” rules on the stock exchange or market. There can be no assurance that the requirements necessary to maintain the listing or trading of Fund shares will continue to be met or will remain unchanged.

Shares of the Fund May Trade at Prices Other Than NAV. Shares of the Fund trade on stock exchanges at prices at, above or below their most recent NAV. The NAV of the Fund is calculated at the end of each business day and fluctuates with changes in the market value of the Fund’s holdings since the most recent calculation. The trading prices of the Fund’s shares fluctuate continuously throughout trading hours based on market supply and demand rather than NAV. The trading prices of the Fund’s shares may deviate significantly from NAV during periods of market volatility. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV. However, because shares can be created and redeemed in Creation Units at NAV (unlike shares of many closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their NAVs), BFA believes that large discounts or premiums to the NAV of the Fund are not likely to be sustained over the long-term. While the creation/redemption feature is designed to make it likely that the Fund’s shares normally will trade on stock exchanges at prices close to the Fund’s next calculated NAV, exchange prices are not expected to correlate exactly with the Fund’s NAV due to timing reasons as well as market supply and demand factors. In addition, disruptions to creations and redemptions or extreme market volatility may result in trading prices for shares of the Fund that differ significantly from its NAV.

Costs of Buying or Selling Fund Shares. Buying or selling Fund shares on an exchange involves two types of costs that apply to all securities transactions. When buying or selling shares of the Fund through a broker, you will likely incur a brokerage commission or other charges imposed by brokers as determined by that broker. In addition, you may incur the cost of the “spread” – that is, the difference between what investors are willing to pay for Fund shares (the “bid” price) and the price at which they are willing to sell Fund shares (the “ask” price). Because of the costs inherent in buying or selling Fund shares, frequent trading may detract significantly from investment

results and an investment in Fund shares may not be advisable for investors who anticipate regularly making small investments.

Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers are subject to all of the risks of investing in the markets where such issuers are located, including heightened risks of inflation or nationalization and market fluctuations caused by economic and political developments. As a result of investing in non-U.S. securities, the Fund may be subject to increased risk of loss caused by any of the factors listed below:

  • Lower levels of liquidity and market efficiency;
  • Greater securities price volatility;
  • Exchange rate fluctuations and exchange controls;
  • Less availability of public information about issuers;
  • Limitations on foreign ownership of securities;
  • Imposition of withholding or other taxes;
  • Imposition of restrictions on the expatriation of the funds or other assets of the Fund;
  • Higher transaction and custody costs and delays in settlement procedures;
  • Difficulties in enforcing contractual obligations;
  • Lower levels of regulation of the securities market;
  • Weaker accounting, disclosure and reporting requirements; and
  • Legal principles related to corporate governance, directors’ fiduciary duties and liabilities and stockholders’ rights in markets in which the Fund invests may differ and/or may not be as extensive or protective as those that apply in the United States.

Passive Investment Risk. The Fund is not actively managed and may be affected by a general decline in market segments related to the Underlying Index. The Fund invests in securities included in, or representative of, the Underlying Index regardless of their investment merits. BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

Reliance on Trading Partners Risk. The economies of some countries in which the Fund invests are dependent on trade with certain key trading partners. Reduction in spending on the products and services of these countries, institution of tariffs or other trade barriers by any of their key trading partners or a slowdown in the economies of any of their key trading partners may cause an adverse impact on the economies of such countries.


U.S. Trading Partners Risk. The United States is a significant trading partner of or foreign investor in certain countries in which the Fund invests and the economies of these countries may be particularly affected by changes in the U.S. economy. Decreasing U.S. imports, new trade regulations, changes in the U.S. dollar exchange rate or a recession in the United States may have a material adverse effect on economies of the countries in which the Fund invests.

Risk of Investing in Japan. Japan may be subject to political, economic, nuclear, and labor risks. Any of these risks, individually or in the aggregate, can impact an investment made in Japan.

  • Political Risk. Historically, Japan has had unpredictable national politics and may experience frequent political turnover. Future political developments may lead to changes in policy that might adversely affect the Fund’s investments.
  • Large Government Debt Risk. The Japanese economy faces several concerns, including a financial system with large levels of nonperforming loans, over-leveraged corporate balance sheets, extensive cross-ownership by major corporations, a changing corporate governance structure, and large government deficits. These issues may cause a slowdown of the Japanese economy.
  • Currency Risk. The Japanese yen has fluctuated widely at times and any increase in its value may cause a decline in exports that could weaken the economy.
  • Nuclear Risk. The nuclear power plant catastrophe in Japan in March of 2011 may have short-term and long-term effects on the nuclear energy industry, the extent of which are currently unknown.
  • Labor Risk. Japan has an aging workforce. It is a labor market that is undergoing fundamental structural changes, as traditional lifetime employment clashes with the need for increased labor mobility, which may adversely affect Japan’s economic competitiveness.
  • Geographic Risk. Natural disasters, such as earthquakes, could occur in Japan or surrounding areas and could negatively affect the Japanese economy, and, in turn, could negatively affect the Fund.

Securities Lending Risk. The Fund may engage in securities lending. Securities lending involves the risk that the Fund may lose money because the borrower of the Fund’s loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for the loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Security Risk. Some geographic areas in which the Fund invests have experienced acts of terrorism or strained international relations due to territorial disputes, historical animosities or other defense concerns. These situations may cause uncertainty in the markets of these geographic areas and may adversely affect the performance of their economies.

Small-Capitalization Companies Risk. Many of the companies in which the Fund invests are considered small-capitalization companies. Stock prices of small-capitalization companies may be more volatile than those of larger companies and, therefore, the Fund’s share price may be more volatile than those of funds that invest a larger percentage of their assets in stocks issued by mid- or large-capitalization companies. Stock prices of small-capitalization companies are generally more vulnerable than those of mid- or large-capitalization companies to adverse business and economic developments. Securities of small-capitalization companies may be

thinly traded, making it difficult for the Fund to buy and sell them. In addition, small-capitalization companies are typically less financially stable than larger, more established companies and may depend on a small number of essential personnel, making them more vulnerable to loss of personnel. Small-capitalization companies also normally have less diverse product lines than mid- or large-capitalization companies and are more susceptible to adverse developments concerning their products.

Tracking Error Risk. Imperfect correlation between the Fund’s portfolio securities and those in the Underlying Index, rounding of prices, changes to the Underlying Index and regulatory requirements may cause tracking error, which is the divergence of the Fund’s performance from that of the Underlying Index. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Underlying Index does not. Because the Fund employs a representative sampling strategy, the Fund may experience tracking error to a greater extent than a fund that seeks to replicate an index.

Valuation Risk. Because non-U.S. exchanges may be open on days when the Fund does not price its shares, the value of the securities in the Fund’s portfolio may change on days when shareholders will not be able to purchase or sell the Fund’s shares. In addition, for purposes of calculating the Fund’s NAV, the value of assets denominated in non-U.S. currencies is converted into U.S. dollars using exchange rates deemed appropriate by BFA. This conversion may result in a difference between the prices used to calculate the Fund’s NAV and the prices used by the Underlying Index, which, in turn, could result in a difference between the Fund’s performance and the performance of the Underlying Index.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

Australasian Economic Risk. The economies of Australasia, which include Australia and New Zealand, are dependent on exports from the agricultural and mining sectors. This makes Australasian economies susceptible to fluctuations in the commodity markets. Australasian economies are also increasingly dependent on their growing service industries. Because the economies of Australasia are dependent on the economies of Asia, Europe and the United States as key trading partners and investors, reduction in spending by any of these trading partners on Australasian products and services, or negative changes in any of these economies, may cause an adverse impact on some or all of the Australasian economies.

Basic Materials Sector Risk. Issuers in the basic materials sector could be adversely affected by commodity price volatility, exchange rates, import controls and increased competition. Production of industrial materials often exceeds demand as a result of over-building or economic downturns, leading to poor investment returns. Issuers in the basic materials sector are at risk for environmental damage and product liability claims and may be adversely affected by depletion of resources, delays in technical progress, labor relations and government regulations.

Consumer Goods Sector Risk. The consumer goods sector may be strongly affected by social trends, marketing campaigns and other factors affecting consumer demand. Governmental regulation affecting the use of various food additives may affect the profitability of certain companies represented in the Underlying Index. In addition, tobacco companies may be adversely affected by new laws, regulations and litigation. Many consumer goods in the United States may also be marketed globally, and such consumer goods companies may be affected by the demand and market conditions in non-U.S. countries.

Health Care Sector Risk. The profitability of companies in the health care sector may be affected by extensive government regulations, restrictions on government reimbursement for medical expenses, rising costs of medical products and services, pricing pressure, an increased emphasis on outpatient services, limited number of products, industry innovation, changes in technologies and other market developments. Many health care companies are heavily dependent on patent protection. The expiration of patents may adversely affect the profitability of these companies. Many health care companies are subject to extensive litigation based on product liability and similar claims. Health care companies are subject to competitive forces that may make it difficult to raise prices and, in fact, may result in price discounting. Many new products in the health care sector may be subject to regulatory approvals. The process of obtaining such approvals may be long and costly. Companies in the health care sector may be thinly capitalized and may be susceptible to product obsolescence.

Technology Sector Risk. The Fund invests in technology companies, which face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Technology companies may have limited product lines, markets, financial resources or personnel. The products of technology companies may face obsolescence due to rapid technological developments and frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Companies in the technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies.

Management

Investment Adviser. As investment adviser, BFA has overall responsibility for the general management and administration of the Trust. BFA provides an investment program for the Fund and manages the investment of the Fund’s assets. In managing the Fund, BFA may draw upon the research and expertise of its asset management affiliates with respect to certain portfolio securities. In seeking to achieve the Fund’s

investment objective, BFA uses teams of portfolio managers, investment strategists and other investment specialists. This team approach brings together many disciplines and leverages BFA’s extensive resources.

Pursuant to the Investment Advisory Agreement between BFA and the Trust (entered into on behalf of the Fund), BFA is responsible for substantially all expenses of the Fund, except interest expenses, taxes, brokerage expenses, future distribution fees or expenses and extraordinary expenses.

For its investment advisory services to the Fund, BFA is entitled to receive a management fee from the Fund based on a percentage of the Fund’s average daily net assets, at the annual rate of 0.50%.

BFA is located at 400 Howard Street, San Francisco, CA 94105. It is a wholly owned subsidiary of BTC, which in turn is indirectly wholly-owned by BlackRock, Inc. (“BlackRock”). As of September 30, 2011, BTC and its affiliates, including BFA and BlackRock, provided investment advisory services for assets in excess of $3.35 trillion. BFA, BTC, BlackRock Execution Services, BlackRock and their affiliates deal, trade and invest for their own accounts in the types of securities in which the Fund may also invest.

A discussion regarding the basis for the Trust’s Board of Trustees’ (the “Board”) approval of the Investment Advisory Agreement with BFA is available in the Fund’s annual report for the period ended July 31.

Portfolio Managers. Rene Casis, Diane Hsiung and Greg Savage are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager is responsible for various functions related to portfolio management, including, but not limited to, investing cash inflows, coordinating with members of his or her portfolio management team to focus on certain asset classes, implementing investment strategy, researching and reviewing investment strategy and overseeing members of his or her portfolio management team that have more limited responsibilities.

Rene Casis has been employed by BFA (formerly, Barclays Global Fund Advisors (“BGFA”)) and BTC (formerly, Barclays Global Investors, N.A. (“BGI”)) as a senior portfolio manager since 2009. From 2005 to 2009, Mr. Casis was a trader at Barclays Capital. Prior to that, Mr. Casis was a portfolio manager from 2000 to 2005 for BGFA and BGI. Mr. Casis has been a Portfolio Manager of the Fund since 2010.

Diane Hsiung has been employed by BFA and BTC as a senior portfolio manager since 2007. Prior to that, Ms. Hsiung was a portfolio manager from 2002 to 2006 for BGFA and BGI. Ms. Hsiung has been a Portfolio Manager of the Fund since 2008.

Greg Savage has been employed by BFA and BTC as a senior portfolio manager since 2006. Prior to that, Mr. Savage was a portfolio manager from 2001 to 2006 for BGFA and BGI. Mr. Savage has been a Portfolio Manager of the Fund since 2008.

The Fund’s SAI provides additional information about the Portfolio Managers’ compensation, other accounts managed by the Portfolio Managers and the Portfolio Managers’ ownership (if any) of shares in the Fund.

Administrator, Custodian and Transfer Agent. State Street Bank and Trust Company (“State Street”) is the administrator, custodian and transfer agent for the Fund.

Conflicts of Interest. BFA wants you to know that there are certain entities with which BFA has relationships that may give rise to conflicts of interest, or the appearance of conflicts of interest. These entities include the following: BFA’s affiliates (including BlackRock and The PNC Financial Services Group, Inc., and each of their affiliates, directors, partners, trustees, managing members, officers and employees (collectively, the “Affiliates”)) and BlackRock’s significant shareholder, Barclays Bank PLC and its affiliates, including Barclays PLC (each, an “Entity” and together, the “Entities”).

The activities of BFA, the Affiliates and the Entities in the management of, or their interest in, their own accounts and other accounts they manage, may present conflicts of interest that could disadvantage the Fund and its shareholders. BFA and its Affiliates or the Entities provide investment management services to other funds and discretionary managed accounts that may follow an investment program similar to that of the Fund. BFA, its Affiliates and the Entities are involved worldwide with a broad spectrum of financial services and asset management activities and may engage in the ordinary course of business in activities in which their interests or the interests of their clients may conflict with those of the Fund. BFA, one or more of the Affiliates or the Entities acts, or may act, as an investor, investment banker, research provider, investment manager, financier, underwriter, advisor, market maker, trader, prime broker, lender, agent or principal, and have other direct and indirect interests, in securities, currencies and other instruments in which the Fund may directly or indirectly invest. Thus, it is likely that the Fund will have multiple business relationships with and will invest in, engage in transactions with, make voting decisions with respect to, or obtain services from, entities for which BFA, an Affiliate or an Entity performs or seeks to perform investment banking or other services.

BFA or one or more Affiliates or Entities may engage in proprietary trading and advise accounts and funds that have investment objectives similar to those of the Fund and/or that engage in and compete for transactions in the same types of securities, currencies and other instruments as the Fund, including in securities issued by other open-end and closed-end investment management companies, including investment companies that are affiliated with the Fund and BFA, to the extent permitted under the Investment Company Act of 1940, as amended (the “1940 Act”). The trading activities of BFA, these Affiliates and Entities are carried out without reference to positions held directly or indirectly by the Fund and may result in BFA, an Affiliate or an Entity having positions that are adverse to those of the Fund.

No Affiliate or Entity is under any obligation to share any investment opportunity, idea or strategy with the Fund. As a result, an Affiliate or an Entity may compete with the Fund for appropriate investment opportunities. As a result of this and several other factors, the results of the Fund’s investment activities may differ from those of an Affiliate or an Entity and of other accounts managed by an Affiliate or an Entity, and it is possible that the Fund could sustain losses during periods in which one or more

Affiliates or Entities and other accounts achieve profits on their trading for proprietary or other accounts. The opposite result is also possible.

The Fund may, from time to time, enter into transactions in which BFA or an Affiliate’s or an Entity’s clients have an interest adverse to the Fund. Furthermore, transactions undertaken by Affiliate-advised clients may adversely impact the Fund. Transactions by one or more Affiliate- or Entity-advised clients or BFA may have the effect of diluting or otherwise disadvantaging the values, prices or investment strategies of the Fund.

An Entity may maintain securities indices as part of its product offerings. Index-based funds seek to track the performance of securities indices and may use the name of the index in the fund name. Index providers, including the Entities, may be paid licensing fees for use of their indices or index names. Entities will not be obligated to license their indices to BFA and its Affiliates, and BFA and its Affiliates will not be assured that the terms of any index licensing agreement with the Entities will be as favorable as those terms offered to other index licensees.

The Fund’s activities may be limited because of regulatory restrictions applicable to one or more Affiliates or Entities, and/or their internal policies designed to comply with such restrictions. In addition, the Fund may invest in securities of companies with which an Affiliate or an Entity has or is trying to develop investment banking relationships or in which an Affiliate or an Entity has significant debt or equity investments. The Fund also may invest in securities of companies for which an Affiliate or an Entity provides or may some day provide research coverage. An Affiliate or an Entity may have business relationships with and purchase or distribute or sell services or products from or to distributors, consultants or others who recommend the Fund or who engage in transactions with or for the Fund, and may receive compensation for such services. The Fund may also make brokerage and other payments to Affiliates or Entities in connection with the Fund’s portfolio investment transactions.

Pursuant to a securities lending program approved by the Board, the Fund has retained an Affiliate of BFA to serve as the securities lending agent for the Fund to the extent that the Fund participates in the securities lending program. For these services, the lending agent may receive a fee from the Fund, including a fee based on the returns earned on the Fund’s investment of the cash received as collateral for any loaned securities. In addition, one or more Affiliates may be among the entities to which the Fund may lend its portfolio securities under the securities lending program.

The activities of BFA, the Affiliates or Entities may give rise to other conflicts of interest that could disadvantage the Fund and its shareholders. BFA has adopted policies and procedures designed to address these potential conflicts of interest. See the Fund’s SAI for further information.

Shareholder Information

Additional shareholder information, including how to buy and sell shares of the Fund, is available free of charge by calling toll-free: 1-800-iShares (1-800-474-2737) or visiting our website at www.iShares.com.

Buying and Selling Shares. Shares of the Fund may be acquired or redeemed directly from the Fund only in Creation Units or multiples thereof, as discussed in the Creations

and Redemptions section of this Prospectus. Only an Authorized Participant (as defined in the Creations and Redemptions section) may engage in creation or redemption transactions directly with the Fund. Once created, shares of the Fund generally trade in the secondary market in amounts less than a Creation Unit.

Shares of the Fund are listed on a national securities exchange for trading during the trading day. Shares can be bought and sold throughout the trading day like shares of other publicly-traded companies. The Trust does not impose any minimum investment for shares of the Fund purchased on an exchange. The Fund’s shares trade under the trading symbol “IFSM.”

Buying or selling Fund shares on an exchange involves two types of costs that may apply to all securities transactions. When buying or selling shares of the Fund through a broker, you will likely incur a brokerage commission or other charges determined by your broker. The commission is frequently a fixed amount and may be a significant proportional cost for investors seeking to buy or sell small amounts of shares. In addition, you may incur the cost of the “spread” – that is, any difference between the bid price and the ask price. The spread varies over time for shares of the Fund based on its trading volume and market liquidity, and is generally lower if the Fund has a lot of trading volume and market liquidity, and higher if the Fund has little trading volume and market liquidity.

The Board has adopted a policy of not monitoring for frequent purchases and redemptions of Fund shares (“frequent trading”) that appear to attempt to take advantage of a potential arbitrage opportunity presented by a lag between a change in the value of the Fund’s portfolio securities after the close of the primary markets for the Fund’s portfolio securities and the reflection of that change in the Fund’s NAV (“market timing”), because the Fund generally sells and redeems its shares directly through transactions that are in-kind and/or for cash, subject to the conditions described below under Creations and Redemptions. The Board has not adopted a policy of monitoring for other frequent trading activity because shares of the Fund are listed for trading on a national securities exchange.

The national securities exchange on which the Fund’s shares are listed is open for trading Monday through Friday and is closed on weekends and the following holidays: New Year’s Day, Martin Luther King, Jr. Day, Presidents’ Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day. The Fund’s primary listing exchange is NASDAQ.

Section 12(d)(1) of the 1940 Act restricts investments by investment companies in the securities of other investment companies. Registered investment companies are permitted to invest in the Fund beyond the limits set forth in Section 12(d)(1), subject to certain terms and conditions set forth in SEC rules or in an SEC exemptive order issued to the Trust. In order for a registered investment company to invest in shares of the Fund beyond the limitations of Section 12(d)(1) pursuant to the exemptive relief obtained by the Trust, the registered investment company must enter into an agreement with the Trust.

Book Entry. Shares of the Fund are held in book-entry form, which means that no stock certificates are issued. The Depository Trust Company (“DTC”) or its nominee is

the record owner of all outstanding shares of the Fund and is recognized as the owner of all shares for all purposes.

Investors owning shares of the Fund are beneficial owners as shown on the records of DTC or its participants. DTC serves as the securities depository for shares of the Fund. DTC participants include securities brokers and dealers, banks, trust companies, clearing corporations and other institutions that directly or indirectly maintain a custodial relationship with DTC. As a beneficial owner of shares, you are not entitled to receive physical delivery of stock certificates or to have shares registered in your name, and you are not considered a registered owner of shares. Therefore, to exercise any right as an owner of shares, you must rely upon the procedures of DTC and its participants. These procedures are the same as those that apply to any other securities that you hold in book-entry or “street name” form.

Share Prices. The trading prices of the Fund’s shares in the secondary market generally differ from the Fund’s daily NAV and are affected by market forces such as supply and demand, economic conditions and other factors. Information regarding the intraday value of shares of the Fund, also known as the “indicative optimized portfolio value” (“IOPV”), is disseminated every 15 seconds throughout the trading day by the national securities exchange on which the Fund’s shares are listed or by market data vendors or other information providers. The IOPV is based on the current market value of the securities and/or cash required to be deposited in exchange for a Creation Unit. The IOPV does not necessarily reflect the precise composition of the current portfolio of securities held by the Fund at a particular point in time or the best possible valuation of the current portfolio. Therefore, the IOPV should not be viewed as a “real-time” update of the Fund’s NAV, which is computed only once a day. The IOPV is generally determined by using both current market quotations and/or price quotations obtained from broker-dealers that may trade in the portfolio securities held by the Fund. The quotations of certain Fund holdings may not be updated during U.S. trading hours if such holdings do not trade in the United States. The Fund is not involved in, or responsible for, the calculation or dissemination of the IOPV and makes no representation or warranty as to its accuracy.

Determination of Net Asset Value. The NAV of the Fund normally is determined once daily Monday through Friday, generally as of the regularly scheduled close of business of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m., Eastern time) on each day that the NYSE is open for trading, based on prices at the time of closing provided that (a) any Fund assets or liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers (as detailed below) and (b) U.S. fixed income assets may be valued as of the announced closing time for trading in fixed income instruments in a particular market or exchange. The NAV of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets held by the Fund, and its liabilities, are determined pursuant to valuation policies and procedures approved by the Board. The Fund’s assets and liabilities are valued primarily on the basis of market quotations.

Equity investments are valued at market value, which is generally determined using the last reported official closing price or last trading price on the exchange or market on which the security is primarily traded at the time of valuation.

The Fund invests in foreign securities. Foreign currency exchange rates are generally determined as of 4:00 p.m., London time. Foreign securities owned by the Fund may trade on weekends or other days when the Fund does not price its shares. As a result, the Fund’s NAV may change on days when Authorized Participants will not be able to purchase or redeem Fund shares.

Generally, trading in foreign securities, U.S. government securities, money market instruments and certain fixed-income securities is substantially completed each day at various times prior to the close of business on the NYSE. The values of such securities used in computing the NAV of the Fund are determined as of such times.

When market quotations are not readily available or are believed by BFA to be unreliable, the Fund’s investments are valued at fair value. Fair value determinations are made by BFA in accordance with policies and procedures approved by the Fund’s Board. BFA may conclude that a market quotation is not readily available or is unreliable if a security or other asset or liability does not have a price source due to its lack of liquidity, if a market quotation differs significantly from recent price quotations or otherwise no longer appears to reflect fair value, where the security or other asset or liability is thinly traded, or where there is a significant event subsequent to the most recent market quotation. A “significant event” is an event that, in the judgment of BFA, is likely to cause a material change to the closing market price of the asset or liability held by the Fund. Foreign securities whose values are affected by volatility that occurs in U.S. markets on a trading day after the close of foreign securities markets may be fair valued.

Fair value represents a good faith approximation of the value of an asset or liability. The fair value of an asset or liability held by the Fund is the amount the Fund might reasonably expect to receive from the current sale of that asset or the cost to extinguish that liability in an arm’s-length transaction. Valuing the Fund’s investments using fair value pricing will result in prices that may differ from current market valuations and that may not be the price at which those investments could have been sold during the period in which the particular fair values were used. Use of fair value prices and certain current market valuations could result in a difference between the prices used to calculate the Fund’s NAV and the prices used by the Underlying Index, which, in turn, could result in a difference between the Fund’s performance and the performance of the Underlying Index.

The value of assets or liabilities denominated in non-U.S. currencies will be converted into U.S. dollars using exchange rates deemed appropriate by BFA as investment adviser. Use of a rate different from the rate used by the Index Provider may adversely affect the Fund’s ability to track the Underlying Index.

Dividends and Distributions

General Policies. Dividends from net investment income, if any, generally are declared and paid semi-annually by the Fund. Distributions of net realized securities gains, if any, generally are declared and paid once a year, but the Trust may make distributions on a more frequent basis for the Fund. The Trust reserves the right to declare special distributions if, in its reasonable discretion, such action is necessary or advisable to preserve its status as a regulated investment company (“RIC”) or to avoid imposition of income or excise taxes on undistributed income or realized gains.

Dividends and other distributions on shares of the Fund are distributed on a pro rata basis to beneficial owners of such shares. Dividend payments are made through DTC participants and indirect participants to beneficial owners then of record with proceeds received from the Fund.

Dividend Reinvestment Service. No dividend reinvestment service is provided by the Trust. Broker-dealers may make available the DTC book-entry Dividend Reinvestment Service for use by beneficial owners of the Fund for reinvestment of their dividend distributions. Beneficial owners should contact their broker to determine the availability and costs of the service and the details of participation therein. Brokers may require beneficial owners to adhere to specific procedures and timetables. If this service is available and used, dividend distributions of both income and realized gains will be automatically reinvested in additional whole shares of the Fund purchased in the secondary market.

Taxes. As with any investment, you should consider how your investment in shares of the Fund will be taxed. The tax information in this Prospectus is provided as general information, based on current law. You should consult your own tax professional about the tax consequences of an investment in shares of the Fund.

Unless your investment in Fund shares is made through a tax-exempt entity or tax-deferred retirement account, such as an IRA, you need to be aware of the possible tax consequences when the Fund makes distributions or you sell Fund shares.

Taxes on Distributions. Distributions from the Fund’s net investment income (other than qualified dividend income), including distributions of income from securities lending and distributions out of the Fund’s net short-term capital gains, if any, are taxable to you as ordinary income. Distributions by the Fund of net long-term capital gains in excess of net short-term capital losses (capital gain dividends) are taxable to you as long-term capital gains, generally at a 15% tax rate (0% at certain income levels), regardless of how long you have held the Fund’s shares. Distributions by the Fund that qualify as qualified dividend income are taxable to you at long-term capital gain rates for taxable years beginning on or before December 31, 2012. The 15% and 0% tax rates expire for taxable years beginning after December 31, 2012. Maximum long-term capital gain income tax rates are scheduled to rise to 20% in 2013. Beginning in 2013, a 3.8% U.S. federal Medicare contribution tax will be imposed on “net investment income,” including interest, dividends, and capital gains, of U.S. individuals with income exceeding $200,000 (or $250,000 if married and filing jointly), and of estates and trusts.

Dividends will be qualified dividend income to you if they are attributable to qualified dividend income received by the Fund. Generally, qualified dividend income includes dividend income from taxable U.S. corporations and qualified non-U.S. corporations, provided that the Fund satisfies certain holding period requirements in respect of the stock of such corporations and has not hedged its position in the stock in certain ways. Substitute dividends received by the Fund with respect to dividends paid on securities lent out will not be qualified dividend income. For this purpose, a qualified non-U.S. corporation means any non-U.S. corporation that is eligible for benefits under a comprehensive income tax treaty with the United States, which includes an exchange of information program or if the stock with respect to which the dividend was paid is readily tradable on an established United States securities market. The term excludes a corporation that is a passive foreign investment company.

Dividends received by the Fund from a real estate investment trust (“REIT”) or another RIC generally are qualified dividend income only to the extent the dividend distributions are made out of qualified dividend income received by such REIT or RIC. It is expected that dividends received by the Fund from a REIT and distributed to a shareholder generally will be taxable to the shareholder as ordinary income.

For a dividend to be treated as qualified dividend income, the dividend must be received with respect to a share of stock held without being hedged by the Fund, and with respect to a share of the Fund held without being hedged by you, for 61 days during the 121-day period beginning at the date which is 60 days before the date on which such share becomes ex-dividend with respect to such dividend or, in the case of certain preferred stock, 91 days during the 181-day period beginning 90 days before such date.

If your Fund shares are loaned out pursuant to a securities lending arrangement, you may lose the ability to use foreign tax credits passed through by the Fund or to treat Fund dividends paid while the shares are held by the borrower as qualified dividend income.

In general, your distributions are subject to U.S. federal income tax for the year when they are paid. Certain distributions paid in January, however, may be treated as paid on December 31 of the prior year.

If the Fund’s distributions exceed current and accumulated earnings and profits, all or a portion of the distributions made in the taxable year may be recharacterized as a return of capital to shareholders. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and result in a higher capital gain or lower capital loss when those shares on which the distribution was received are sold. Once a shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain, if the shareholder holds shares of the Fund as capital assets.

If you are neither a resident nor a citizen of the United States or if you are a non-U.S. entity, the Fund’s ordinary income dividends (which include distributions of net short-term capital gains) will generally be subject to a 30% U.S. withholding tax, unless a lower treaty rate applies, provided that withholding tax will generally not apply to any gain or income realized by a non-U.S. shareholder in respect of any distributions of long-term capital gains or upon the sale or other disposition of shares of the Fund.

A 30% withholding tax will be imposed on dividends paid after December 31, 2013, and redemption proceeds paid after December 31, 2014, to (i) foreign financial institutions including non-U.S. investment funds unless they agree to collect and disclose to the Internal Revenue Service (“IRS”) information regarding their direct and indirect U.S. account holders and (ii) certain other foreign entities, unless they certify certain information regarding their direct and indirect U.S. owners. To avoid withholding, foreign financial institutions will need to enter into agreements with the IRS that state that they will provide the IRS information, including the name, address and taxpayer identification number of direct and indirect U.S. account holders, comply with due diligence procedures with respect to the identification of U.S. accounts, report to the IRS certain information with respect to U.S. accounts maintained, agree to withhold tax on certain payments made to non-compliant foreign financial institutions or to account holders who fail to provide the required information, and determine certain other information as to their account holders. Other foreign entities will need to provide the name, address, and taxpayer identification number of each substantial U.S. owner or certifications of no substantial U.S. ownership unless certain exceptions apply.

Dividends, interest and capital gains earned by the Fund with respect to non-U.S. securities may give rise to withholding and other taxes imposed by non-U.S. countries. Tax conventions between certain countries and the United States may reduce or eliminate such taxes. If more than 50% of the total assets of the Fund at the close of a year consists of non-U.S. stocks or securities, the Fund may “pass through” to you certain non-U.S. income taxes (including withholding taxes) paid by the Fund. This means that you would be considered to have received as an additional dividend your share of such non-U.S. taxes, but you may be entitled to either a corresponding tax deduction in calculating your taxable income, or, subject to certain limitations, a credit in calculating your U.S. federal income tax.

For purposes of foreign tax credits for U.S. shareholders of the Fund, foreign capital gains taxes may not produce associated foreign source income, thereby limiting a U.S. person’s ability to use such credits.

If you are a resident or a citizen of the United States, by law, back-up withholding will apply to your distributions and proceeds if you have not provided a taxpayer identification number or social security number and made other required certifications.

Taxes When Shares are Sold. Currently, any capital gain or loss realized upon a sale of Fund shares is generally treated as a long-term gain or loss if the shares have been held for more than one year. Any capital gain or loss realized upon a sale of Fund shares held for one year or less is generally treated as short-term gain or loss, except that any capital loss on the sale of shares held for six months or less is treated as long-term capital loss to the extent that capital gain dividends were paid with respect to such shares. Beginning in 2013, any such capital gains, including from sales of Fund shares or from capital gain dividends, will be included in “net investment income” for purposes of the 3.8% U.S. federal Medicare contribution tax mentioned above.

The foregoing discussion summarizes some of the consequences under current U.S. federal tax law of an investment in the Fund. It is not a substitute for personal tax advice. You may also be subject to state and local taxation on Fund distributions and sales of

shares. Consult your personal tax adviser about the potential tax consequences of an investment in shares of the Fund under all applicable tax laws.

Creations and Redemptions. Prior to trading in the secondary market, shares of the Fund are “created” at NAV by market makers, large investors and institutions only in block-size Creation Units of 200,000 shares or multiples thereof. Each “creator” or “Authorized Participant” enters into an authorized participant agreement with the Fund’s distributor, SEI Investments Distribution Co. (the “Distributor”). Only an Authorized Participant may create or redeem Creation Units directly with the Fund. A creation transaction, which is subject to acceptance by the transfer agent, generally takes place when an Authorized Participant deposits into the Fund a designated portfolio of securities and a specified amount of cash approximating the holdings of the Fund in exchange for a specified number of Creation Units. To the extent practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund.

Similarly, shares can be redeemed only in Creation Units, generally for a designated portfolio of securities and a specified amount of cash held by the Fund (“Fund Securities”). Except when aggregated in Creation Units, shares are not redeemable by the Fund. The prices at which creations and redemptions occur are based on the next calculation of NAV after an order is received in a form described in the authorized participant agreement.

The Fund intends to comply with the U.S. federal securities laws in accepting securities for deposit and satisfying redemptions with redemption securities by, among other means, assuring that any securities accepted for deposit and any securities used to satisfy redemption requests will be sold in transactions that would be exempt from registration under the Securities Act of 1933, as amended (the “1933 Act”). Further, an Authorized Participant that is not a “qualified institutional buyer,” as such term is defined under Rule 144A of the 1933 Act, will not be able to receive Fund Securities that are restricted securities eligible for resale under Rule 144A.

Creations and redemptions must be made through a firm that is either a member of the Continuous Net Settlement System of the National Securities Clearing Corporation or a DTC participant and has executed an agreement with the Distributor with respect to creations and redemptions of Creation Unit aggregations. Information about the procedures regarding creation and redemption of Creation Units (including the cut-off times for receipt of creation and redemption orders) is included in the Fund’s SAI.

Because new shares may be created and issued on an ongoing basis, at any point during the life of the Fund a “distribution,” as such term is used in the 1933 Act, may be occurring. Broker-dealers and other persons are cautioned that some activities on their part may, depending on the circumstances, result in their being deemed participants in a distribution in a manner that could render them statutory underwriters and subject to the prospectus delivery and liability provisions of the 1933 Act. Any determination of whether one is an underwriter must take into account all the relevant facts and circumstances of each particular case.

Broker-dealers should also note that dealers who are not “underwriters” but are participating in a distribution (as contrasted to ordinary secondary transactions), and

thus dealing with shares that are part of an “unsold allotment” within the meaning of Section 4(3)(C) of the 1933 Act, would be unable to take advantage of the prospectus delivery exemption provided by Section 4(3) of the 1933 Act. For delivery of prospectuses to exchange members, the prospectus delivery mechanism of Rule 153 under the 1933 Act is available only with respect to transactions on a national securities exchange.

Costs Associated with Creations and Redemptions. Authorized Participants are charged standard creation and redemption transaction fees to offset transfer and other transaction costs associated with the issuance and redemption of Creation Units. The standard creation and redemption transaction fees are set forth in the table below. The standard creation transaction fee is charged to the Authorized Participant on the day such Authorized Participant creates a Creation Unit, and is the same regardless of the number of Creation Units purchased by the Authorized Participant on the applicable business day. Similarly, the standard redemption transaction fee is charged to the Authorized Participant on the day such Authorized Participant redeems a Creation Unit, and is the same regardless of the number of Creation Units redeemed by the Authorized Participant on the applicable business day. Creations and redemptions for cash (when cash creations and redemptions (in whole or in part) are available or specified) are also subject to an additional charge (up to the maximum amounts shown in the table below). This charge is intended to compensate for brokerage, tax, foreign exchange, execution, market impact and other costs and expenses related to cash transactions. Investors who use the services of a broker or other financial intermediary may pay fees for such services.

The following table shows, as of September 30, 2011, the approximate value of one Creation Unit, standard fees and maximum additional charges for creations and redemptions (as described above):

Householding. Householding is an option available to certain Fund investors. Householding is a method of delivery, based on the preference of the individual investor, in which a single copy of certain shareholder documents can be delivered to investors who share the same address, even if their accounts are registered under different names. Please contact your broker-dealer if you are interested in enrolling in householding and receiving a single copy of prospectuses and other shareholder documents, or if you are currently enrolled in householding and wish to change your householding status.

Distribution

The Distributor distributes Creation Units for the Fund on an agency basis. The Distributor does not maintain a secondary market in shares of the Fund. The Distributor has no role in determining the policies of the Fund or the securities that are purchased or sold by the Fund. The Distributor’s principal address is One Freedom Valley Drive, Oaks, PA 19456.

In addition, BFA or its Affiliates make payments to broker-dealers, banks or other financial intermediaries (together, “intermediaries”) related to marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems, or their making shares of the Fund and certain other iShares funds available to their customers. Such payments, which may be significant to the intermediary, are not made by the Fund. Rather, such payments are made by BFA or its Affiliates from their own resources, which come directly or indirectly in part from fees paid by the iShares funds complex. Payments of this type are sometimes referred to as revenue-sharing payments. A financial intermediary may make decisions about which investment options it recommends or makes available, or the level of services provided, to its customers based on the revenue-sharing payments it is eligible to receive. Therefore, such payments to an intermediary create conflicts of interest between the intermediary and its customers and may cause the intermediary to recommend the Fund or other iShares funds over another investment. More information regarding these payments is contained in the Fund’s SAI. Please contact your salesperson or other investment professional for more information regarding any such payments his or her firm may receive from BFA or its Affiliates.

Financial Highlights

The financial highlights table is intended to help investors understand the Fund’s financial performance since inception. Certain information reflects financial results for a single share of the Fund. The total returns in the table represent the rate that an investor would have earned (or lost) on an investment in the Fund, assuming reinvestment of all dividends and distributions. This information has been audited by PricewaterhouseCoopers LLP, whose report is included, along with the Fund’s financial statements, in the Fund’s Annual Report (available upon request).

Supplemental Information

I. Premium/Discount Information

The table that follows presents information about the differences between the daily market price on secondary markets for shares of the Fund and the Fund’s NAV. NAV is the price at which the Fund issues and redeems shares. It is calculated in accordance with the standard formula for valuing mutual fund shares. The price used to calculate market returns (“Market Price”) of the Fund generally is determined using the midpoint between the highest bid and the lowest offer on the primary securities exchange on which shares of the Fund are listed for trading, as of the time that the Fund’s NAV is calculated. The Fund’s Market Price may be at, above or below its NAV. The NAV of the Fund will fluctuate with changes in the value of its portfolio holdings. The Market Price of the Fund will fluctuate in accordance with changes in its NAV, as well as market supply and demand.

Premiums or discounts are the differences (expressed as a percentage) between the NAV and Market Price of the Fund on a given day, generally at the time the NAV is calculated. A premium is the amount that the Fund is trading above the reported NAV, expressed as a percentage of the NAV. A discount is the amount that the Fund is trading below the reported NAV, expressed as a percentage of the NAV.

The following information shows the frequency of distributions of premiums and discounts for the Fund for each full calendar quarter of 2010 through September 30, 2011.

Each line in the table shows the number of trading days in which the Fund traded within the premium/discount range indicated. The number of trading days in each premium/discount range is also shown as a percentage of the total number of trading days in the period covered by the table. All data presented here represents past performance, which cannot be used to predict future results.

II. Total Return Information

The table that follows presents information about the total returns of the Fund and the Underlying Index as of the fiscal year ended July 31, 2011.

“Average Annual Total Returns” represent the average annual change in value of an investment over the periods indicated. “Cumulative Total Returns” represent the total change in value of an investment over the period indicated.

The Fund’s NAV is the value of one share of the Fund as calculated in accordance with the standard formula for valuing mutual fund shares. The NAV return is based on the NAV of the Fund and the market return is based on the Market Price of the Fund. Market Price is determined by using the midpoint between the highest bid and the lowest offer on the primary stock exchange on which shares of the Fund are listed for trading, as of the time that the Fund’s NAV is calculated. Since shares of the Fund did not trade in the secondary market until after the Fund’s inception, for the period from inception to the first day of secondary market trading in shares of the Fund, the NAV of the Fund is used as a proxy for the Market Price to calculate market returns. Market and NAV returns assume that dividends and capital gain distributions have been reinvested in the Fund at Market Price and NAV, respectively.

An index is a statistical composite that tracks a specified financial market or sector. Unlike the Fund, the Underlying Index does not actually hold a portfolio of securities and therefore does not incur the expenses incurred by the Fund. These expenses negatively impact the performance of the Fund. Also, market returns do not include brokerage commissions that may be payable on secondary market transactions. If brokerage commissions were included, market returns would be lower. The returns shown in the following table do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption or sale of Fund shares. The investment return and principal value of shares of the Fund will vary with changes in market conditions. Shares of the Fund may be worth more or less than their original cost when they are redeemed or sold in the market. The Fund’s past performance is no guarantee of future results.

Fund Overview

iSHARES® FTSE CHINA 25
INDEX FUND

Ticker: FXI Stock Exchange: NYSE Arca

Investment Objective

The iShares FTSE China 25 Index Fund (the “Fund”) seeks investment results that correspond generally to the price and yield performance, before fees and expenses, of the FTSE China 25 Index (the “Underlying Index”).

Fees and Expenses

The following table describes the fees and expenses that you will incur if you own shares of the Fund. The investment advisory agreement between iShares Trust (the “Trust”) and BlackRock Fund Advisors (“BFA”) (the “Investment Advisory Agreement”) provides that BFA will pay all operating expenses of the Fund, except interest expenses, taxes, brokerage expenses, future distribution fees or expenses, and extraordinary expenses.

You may also incur usual and customary brokerage commissions when buying or selling shares of the Fund, which are not reflected in the example that follows:

Example. This Example is intended to help you compare the cost of owning shares of the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

3 Years
5 Years
10 Years
$74 $230 $401 $894

Portfolio Turnover. The Fund may pay transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 23% of the average value of its portfolio.

Principal Investment Strategies

The Underlying Index is designed to represent the performance of the largest companies in the Chinese equity market that are available to international investors. The Underlying Index consists of 25 of the largest and most liquid Chinese companies. Securities in the Underlying Index are weighted based on the total market value of their shares, so that securities with higher total market values generally have a higher representation in the Underlying Index. Each security in the Underlying Index is a current constituent of the FTSE All-World Index. All of the securities in the Underlying Index currently trade on the Hong Kong Stock Exchange. Component companies include financial, oil & gas and telecommunication companies.

BFA uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to “beat” the index it tracks and does not seek temporary defensive positions when markets decline or appear overvalued.

Indexing may eliminate the chance that the Fund will substantially outperform the Underlying Index but also may reduce some of the risks of active management, such as poor security selection. Indexing seeks to achieve lower costs and better after-tax performance by keeping portfolio turnover low in comparison to actively managed investment companies.

BFA uses a representative sampling indexing strategy to manage the Fund. “Representative sampling” is an indexing strategy that involves investing in a representative sample of securities that collectively has an investment profile similar to the Underlying Index. The securities selected are expected to have, in the aggregate, investment characteristics (based on factors such as market capitalization and industry weightings), fundamental characteristics (such as return variability and yield) and liquidity measures similar to those of the Underlying Index. The Fund may or may not hold all of the securities in the Underlying Index.

The Fund generally invests at least 90% of its assets in securities of the Underlying Index and in depositary receipts representing securities of the Underlying Index. The Fund may invest the remainder of its assets in securities not included in the Underlying Index, but which BFA believes will help the Fund track the Underlying Index and in other investments including futures contracts, options on futures contracts, options and swaps as well as cash and cash equivalents, including shares of money market funds advised by BFA or its affiliates.

The Fund may lend securities representing up to one-third of the

S-2   


Table Of Contents



value of the Fund’s total assets (including the value of the collateral received).

The Underlying Index is sponsored by an organization (the “Index Provider”) that is independent of the Fund and BFA. The Index Provider determines the composition and relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index. The Fund’s Index Provider is FTSE International Limited (“FTSE”).

Industry Concentration Policy. The Fund will concentrate its investments (i.e., hold 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. For purposes of this limitation, securities of the U.S. government (including its agencies and instrumentalities) and repurchase agreements collateralized by U.S. government securities are not considered to be issued by members of any industry.

Summary of Principal Risks

As with any investment, you could lose all or part of your investment in the Fund, and the Fund’s performance could trail that of other investments. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund’s net asset value per share (“NAV”), trading price, yield, total return and ability to meet its investment objective.

Asset Class Risk. Securities in the Underlying Index or in the Fund’s portfolio may underperform in comparison to the general securities markets or other asset classes.

Concentration Risk. To the extent that the Fund’s investments are concentrated in China, a particular issuer, market, industry or asset class, the Fund may be susceptible to loss due to adverse occurrences affecting China, a particular issuer, market, industry or asset class.

Currency Risk. Because the Fund’s NAV is determined in U.S. dollars, the Fund’s NAV could decline if the currency of a non-U.S. market in which the Fund invests depreciates against the U.S. dollar.

Custody Risk. Less developed markets are more likely to experience problems with the clearing and settling of trades and the holding of securities by local banks, agents and depositories.

Emerging Markets Risk. The Fund’s investments in China may be subject to a greater risk of loss than investments in more developed markets. Emerging markets may be more likely to experience inflation risk, political turmoil and rapid changes in economic conditions than more developed markets. Emerging markets often have less uniformity in accounting and reporting requirements, unreliable securities valuation and greater risk associated with custody of securities.

Equity Securities Risk. Equity securities are subject to changes in value and their values may be more volatile than other asset classes.

Financial Sector Risk. The Fund may invest significantly in companies in the financial sector. Performance of companies in the financial sector may be adversely impacted by many factors, including, among others, government regulations, economic conditions, credit rating downgrades, changes in interest rates, and decreased liquidity in credit

S-3   


Table Of Contents



markets. Market conditions and regulation in China may be particularly subject to change based on government policy. This sector has experienced significant losses in the recent past, and the impact of more stringent capital requirements and of recent or future regulation on any individual financial company or on the sector as a whole cannot be predicted.

Geographic Risk. A natural or other disaster could occur in China, causing an adverse impact on the Fund and the companies to which it has exposure.

Issuer Risk. Fund performance depends on the performance of individual securities to which the Fund has exposure. Changes to the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA’s investment management strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares, losses from trading in secondary markets, periods of high volatility and disruption in the creation/redemption process of the Fund. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV.

Non-Diversification Risk. The Fund may invest a large percentage of its assets in securities issued by or representing a small number of issuers. As a result, the Fund’s performance may depend on the performance of a small number of issuers.

Non-U.S. Securities Risk. Investments that track the value of Chinese issuers are subject to the risks associated with investing in China, such as heightened risks of inflation or nationalization. The Fund may lose money due to political, economic and geographic events affecting a non-U.S. issuer or market. The Fund is specifically exposed to Asian Economic Risk.

Oil and Gas Sector Risk. Companies in the oil and gas sector are affected by worldwide energy prices, exploration and production costs. Companies in the oil and gas sector may have significant operations in areas at risk for natural disasters, social unrest and environmental damage. These companies may also be at risk for increased government regulation and intervention, litigation, and negative publicity and perception.

Passive Investment Risk. The Fund is not actively managed and BFA does not attempt to take defensive positions under any market conditions, including declining markets.

Privatization Risk. The country in which the Fund invests has begun a process of privatizing certain entities and industries. Privatized entities may lose money or be re-nationalized.

Reliance on Trading Partners Risk. The Fund invests in an economy that is heavily dependent upon trading with key partners. Any reduction in this trading may have an adverse impact on the Fund’s investments. Through its trading partners, the Fund is particularly exposed to U.S. Trading Partner Risk.



S-4   


Table Of Contents



Risk of Investing in China. China may be subject to considerable degrees of economic, political and social instability.

Securities Lending Risk. The Fund may engage in securities lending. Securities lending involves the risk that the Fund may lose money because the borrower of the Fund’s loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Security Risk. The country in which the Fund invests has experienced security concerns. Incidents involving the country’s or region’s security may cause uncertainty in these markets and may adversely affect their economies and the Fund’s investments.

Telecommunications Sector Risk. Companies in the telecommunications sector may be affected by industry competition, substantial capital requirements, government regulation and obsolescence of telecommunications products and services due to technological advancement.

Tracking Error Risk. The performance of the Fund may diverge from that of the Underlying Index. Because the Fund employs a representative sampling strategy, the Fund may experience tracking error to a greater extent than a fund that seeks to replicate an index.

Valuation Risk. The value of the securities in the Fund’s portfolio may change on days when shareholders will not be able to purchase or sell the Fund’s shares.

1 After-tax returns in the table above are calculated using the historical highest individual U.S. federal marginal income tax rates and do not reflect the impact of state or local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown, and after-tax returns shown are not relevant to tax-exempt investors or investors who hold shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts (“IRAs”). Fund returns after taxes on distributions and sale of Fund shares are calculated assuming that an investor has sufficient capital gains of the same character from other investments to offset any capital losses from the sale of Fund shares. As a result, Fund returns after taxes on distributions and sale of Fund shares may exceed Fund returns before taxes and/or returns after taxes on distributions.

Management

Investment Adviser. BlackRock Fund Advisors.

Portfolio Managers. Christopher Bliss, Rene Casis, Diane Hsiung and Greg Savage (the “Portfolio Managers”) are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager supervises a portfolio management team. Mr. Bliss has been a Portfolio Manager of the Fund since 2011. Mr. Casis has been a Portfolio Manager of the Fund since 2010. Ms. Hsiung and Mr. Savage have been Portfolio Managers of the Fund since 2008.

Purchase and Sale of Fund Shares

The Fund is an exchange-traded fund (commonly referred to as an “ETF”). Individual Fund shares may only be purchased and sold on a national securities exchange through a broker-dealer. The price of Fund shares is based on market price, and because ETF shares trade at market prices rather than NAV, shares may trade at a price greater than NAV (a premium) or less than NAV (a discount). The Fund will only issue or redeem shares that have been aggregated into blocks of 150,000 shares or multiples thereof (“Creation Units”) to authorized participants who have entered into agreements with the Fund’s distributor. The Fund generally will issue or redeem Creation Units in return for a designated portfolio of securities (and an amount of cash) that the Fund specifies each day.

Tax Information

The Fund intends to make distributions that may be taxable to you as ordinary income or capital gains, unless you are investing through a tax-deferred arrangement such as a 401(k) plan or an IRA.

If you purchase shares of the Fund through a broker-dealer or other financial intermediary (such as a bank), BFA or other related companies may pay the intermediary for marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems or other services related to the sale or promotion of the Fund. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.

More Information About the Fund

This Prospectus contains important information about investing in the Fund. Please read this Prospectus carefully before you make any investment decisions. Additional information regarding the Fund is available at www.iShares.com.

On December 16, 2010, the name of the Fund changed from the iShares FTSE/Xinhua China 25 Index Fund to the iShares FTSE China 25 Index Fund to reflect a change in the name of the Fund’s Underlying Index from FTSE/Xinhua China 25 Index to FTSE China 25 Index.

BFA is the investment adviser to the Fund. Shares of the Fund are listed for trading on NYSE Arca, Inc. (“NYSE Arca”). The market price for a share of the Fund may be different from the Fund’s most recent NAV.

ETFs are funds that trade like other publicly-traded securities. The Fund is designed to track an index. Similar to shares of an index mutual fund, each share of the Fund represents a partial ownership in an underlying portfolio of securities intended to track a market index. Unlike shares of a mutual fund, which can be bought and redeemed from the issuing fund by all shareholders at a price based on NAV, shares of the Fund may be purchased or redeemed directly from the Fund at NAV solely by authorized participants. Also unlike shares of a mutual fund, shares of the Fund are listed on a national securities exchange and trade in the secondary market at market prices that change throughout the day.

The Fund invests in a particular segment of the securities markets and seeks to track the performance of a securities index that generally is not representative of the market as a whole. The Fund is designed to be used as part of broader asset allocation strategies. Accordingly, an investment in the Fund should not constitute a complete investment program.

An index is a theoretical financial calculation while the Fund is an actual investment portfolio. The performance of the Fund and the Underlying Index may vary due to transaction costs, non-U.S. currency valuations, asset valuations, corporate actions (such as mergers and spin-offs), timing variances and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions (such as diversification requirements) that apply to the Fund but not to the Underlying Index or to the use of representative sampling. “Tracking error” is the difference between the performance (return) of the Fund’s portfolio and that of the Underlying Index. BFA expects that, over time, the Fund’s tracking error will not exceed 5%. Because the Fund uses a representative sampling indexing strategy, it can be expected to have a larger tracking error than if it used a replication indexing strategy. “Replication” is an indexing strategy in which a fund invests in substantially all of the securities in its underlying index in approximately the same proportions as in the underlying index.

An investment in the Fund is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, BFA or any of its affiliates.

The Fund’s investment objective and the Underlying Index may be changed without shareholder approval.

A Further Discussion of Principal Risks

The Fund is subject to various risks, including the principal risks noted below, any of which may adversely affect the Fund’s NAV, trading price, yield, total return and ability to meet its investment objective. You could lose all or part of your investment in the Fund, and the Fund could underperform other investments.

Asian Economic Risk. Certain Asian economies have experienced over-extension of credit, currency devaluations and restrictions, high unemployment, high inflation, decreased exports and economic recessions. Economic events in any one Asian country may have a significant economic effect on the entire Asian region, and any adverse events in the Asian markets may have a significant adverse effect on Chinese companies.

Asset Class Risk. The securities in the Underlying Index or in the Fund’s portfolio may underperform the returns of other securities or indexes that track other countries, groups of countries, regions, industries, groups of industries, markets, asset classes or sectors. Various types of securities or indexes tend to experience cycles of outperformance and underperformance in comparison to the general securities markets.

Concentration Risk. To the extent that the Fund’s portfolio reflects the Underlying Index’s concentration in the securities of a particular issuer or issuers in a particular country, group of countries, market, industry, group of industries, sector or asset class, the Fund may be adversely affected by the performance of those securities, may be subject to increased price volatility and may be more susceptible to adverse economic, market, political or regulatory occurrences affecting that issuer, country, group of countries, market, industry, group of industries, sector or asset class.

Currency Risk. Because the Fund’s NAV is determined on the basis of the U.S. dollar, investors may lose money if the currency of a non-U.S. market in which the Fund invests depreciates against the U.S. dollar, even if the local currency value of the Fund’s holdings in that market increases.

Custody Risk. Custody risk refers to the risks inherent in the process of clearing and settling trades and the holding of securities by local banks, agents and depositories. Low trading volumes and volatile prices in less developed markets may make trades harder to complete and settle, and governments or trade groups may compel local agents to hold securities in designated depositories that are not subject to independent evaluation. Local agents are held only to the standards of care of their local markets. In general, the less developed a country’s securities market is, the greater the likelihood of custody problems.

Emerging Markets Risk. China is one of the largest global emerging markets. Investments in emerging markets are subject to a greater risk of loss than investments in more developed markets. This is due to, among other things, greater market volatility, lower trading volume, political and economic instability, greater risk of a

market shutdown and more governmental limitations on foreign investments than typically found in more developed markets.

Equity Securities Risk. The Fund invests in equity securities, which are subject to changes in value that may be attributable to market perception of a particular issuer or to general stock market fluctuations that affect all issuers. Investments in equity securities may be more volatile than investments in other asset classes.

Financial Sector Risk. Companies in the financial sector of an economy are often subject to governmental regulation and, recently, government intervention and the potential for additional regulation, which may adversely affect the scope of their activities, the prices they can charge and the amount of capital they must maintain. Governmental regulation may change frequently and may have significant adverse consequences for companies in the financial sector, including effects not intended by such regulation. The impact of recent or future regulation in various countries on any individual financial company or on the sector as a whole cannot be predicted. Certain risks may impact the value of investments in the financial sector more severely than investments outside this sector, including the risks associated with companies that operate with substantial financial leverage. Companies in the financial sector may also be adversely affected by increases in interest rates and loan losses, decreases in the availability of money or asset valuations, credit rating downgrades and adverse conditions in other related markets. Over the past few years, the deterioration of the credit markets has impacted a broad range of mortgage, asset-backed, auction rate, sovereign debt and other markets, including U.S. and non-U.S. credit and interbank money markets, thereby affecting a wide range of financial institutions and markets. This situation has created instability in the financial markets and caused certain financial companies to incur large losses. Some financial companies have experienced declines in the valuations of their assets, taken actions to raise capital (such as the issuance of debt or equity securities), or even ceased operations. Some financial companies have borrowed significant amounts of capital from governments and may face future government-imposed restrictions on their businesses or increased government intervention. These actions have caused the securities of many financial companies to decline in value. Insurance companies, in particular, may be subject to severe price competition, which may have an adverse impact on their profitability. Chinese financial sector regulation and ownership may be more intrusive than in the United States and other developed countries, especially with respect to the regulation of non-Chinese banks and other non-Chinese financial companies. Greater Chinese governmental involvement in the financial sector may pose additional risks for investors. Market conditions and regulation in China may be particularly subject to change based on government policy.

Geographic Risk. China historically has experienced natural disasters such as earthquakes, droughts and floods and is economically sensitive to environmental events. Any such event could cause a significant impact on the Chinese economy.

Issuer Risk. The performance of the Fund depends on the performance of individual securities to which the Fund has exposure. Any issuer of these securities may perform poorly, causing the value of its securities to decline. Poor performance may be caused by poor management decisions, competitive pressures, changes in technology,

expiration of patent protection, disruptions in supply, labor problems or shortages, corporate restructurings, fraudulent disclosures or other factors. Issuers may, in times of distress or at their own discretion, decide to reduce or eliminate dividends, which may also cause their stock prices to decline.

Management Risk. The Fund may not fully replicate the Underlying Index and may hold securities not included in the Underlying Index. As a result, the Fund is subject to the risk that BFA’s investment management strategy, the implementation of which is subject to a number of constraints, may not produce the intended results.

Market Risk. The Fund could lose money due to short-term market movements and over longer periods during market downturns. Securities may decline in value due to factors affecting securities markets generally or particular industries represented in the markets. The value of a security may decline due to general market conditions, economic trends or events that are not specifically related to the issuer of the security or to factors that affect a particular industry or industries. During a general downturn in the securities markets, multiple asset classes may be negatively affected.

Market Trading Risk

Absence of Active Market. Although shares of the Fund are listed for trading on one or more stock exchanges, there can be no assurance that an active trading market for such shares will develop or be maintained.

Risk of Secondary Listings. The Fund’s shares may be listed or traded on U.S. and non-U.S. stock exchanges other than the U.S. stock exchange where the Fund’s primary listing is maintained. There can be no assurance that the Fund’s shares will continue to trade on any such stock exchange or in any market or that the Fund’s shares will continue to meet the requirements for listing or trading on any exchange or in any market. The Fund’s shares may be less actively traded in certain markets than others, and investors are subject to the execution and settlement risks and market standards of the market where they or their broker direct their trades for execution. Certain information available to investors who trade Fund shares on a U.S. stock exchange during regular U.S. market hours may not be available to investors who trade in other markets, which may result in secondary market prices in such markets being less efficient.

Secondary Market Trading Risk. Shares of the Fund may trade in the secondary market at times when the Fund does not accept orders to purchase or redeem shares. At such times, shares may trade in the secondary market with more significant premiums or discounts than might be experienced at times when the Fund accepts purchase and redemption orders.

Secondary market trading in Fund shares may be halted by a stock exchange because of market conditions or other reasons. In addition, trading in Fund shares on a stock exchange or in any market may be subject to trading halts caused by extraordinary market volatility pursuant to “circuit breaker” rules on the stock exchange or market. There can be no assurance that the requirements necessary to maintain the listing or trading of Fund shares will continue to be met or will remain unchanged.

Shares of the Fund May Trade at Prices Other Than NAV. Shares of the Fund trade on stock exchanges at prices at, above or below their most recent NAV. The NAV of the

Fund is calculated at the end of each business day and fluctuates with changes in the market value of the Fund’s holdings since the most recent calculation. The trading prices of the Fund’s shares fluctuate continuously throughout trading hours based on market supply and demand rather than NAV. The trading prices of the Fund’s shares may deviate significantly from NAV during periods of market volatility. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV. However, because shares can be created and redeemed in Creation Units at NAV (unlike shares of many closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their NAVs), BFA believes that large discounts or premiums to the NAV of the Fund are not likely to be sustained over the long-term. While the creation/redemption feature is designed to make it likely that the Fund’s shares normally will trade on stock exchanges at prices close to the Fund’s next calculated NAV, exchange prices are not expected to correlate exactly with the Fund’s NAV due to timing reasons as well as market supply and demand factors. In addition, disruptions to creations and redemptions or extreme market volatility may result in trading prices for shares of the Fund that differ significantly from its NAV.

Costs of Buying or Selling Fund Shares. Buying or selling Fund shares on an exchange involves two types of costs that apply to all securities transactions. When buying or selling shares of the Fund through a broker, you will likely incur a brokerage commission or other charges imposed by brokers as determined by that broker. In addition, you may incur the cost of the “spread” – that is, the difference between what investors are willing to pay for Fund shares (the “bid” price) and the price at which they are willing to sell Fund shares (the “ask” price). Because of the costs inherent in buying or selling Fund shares, frequent trading may detract significantly from investment results and an investment in Fund shares may not be advisable for investors who anticipate regularly making small investments.

Non-Diversification Risk. The Fund is classified as “non-diversified.” This means that the Fund may invest a large percentage of its assets in securities issued by or representing a small number of issuers. As a result, the Fund may be more susceptible to the risks associated with these particular issuers, or to a single economic, political or regulatory occurrence affecting these issuers.

Non-U.S. Securities Risk. Investments that track the value of Chinese issuers are subject to all of the risks of investing in China, including heightened risks of inflation or nationalization and market fluctuations caused by economic and political developments. As a result of investing in securities that track the value of Chinese issuers, the Fund may be subject to increased risk of loss caused by any of the factors listed below:

  • Lower levels of liquidity and market efficiency;
  • Greater securities price volatility;
  • Exchange rate fluctuations and exchange controls;
  • Less availability of public information about issuers;
  • Limitations on foreign ownership of securities;
  • Imposition of withholding or other taxes;
  • Imposition of restrictions on the expatriation of the funds or other assets of the Fund;
  • Higher transaction and custody costs and delays in settlement procedures;
  • Difficulties in enforcing contractual obligations;
  • Lower levels of regulation of the securities market;
  • Weaker accounting, disclosure and reporting requirements; and
  • Legal principles related to corporate governance, directors’ fiduciary duties and liabilities and stockholders’ rights in markets in which the Fund invests may differ and/or may not be as extensive or protective as those that apply in the United States.

Oil and Gas Sector Risk. The profitability of companies in the oil and gas sector is related to worldwide energy prices, exploration, and production spending. Companies in the oil and gas sector may be adversely affected by natural disasters or other catastrophes. Companies in the oil and gas sector may be at risk for environmental damage claims and other types of litigation. Companies in the oil and gas sector may be adversely affected by changes in exchange rates, interest rates, changes in prices for competitive energy services, economic conditions, tax treatment, government regulation and intervention, negative perception and world events in the regions where companies operate (e.g., expropriation, nationalization, confiscation of assets and property or imposition of restrictions on foreign investments and repatriation of capital, military coups, social unrest, violence or labor unrest). Companies in the oil and gas sector may have significant capital investments in, or engage in transactions involving, emerging market countries, which may heighten these risks.

Passive Investment Risk. The Fund is not actively managed and may be affected by a general decline in market segments related to the Underlying Index. The Fund invests in securities included in, or representative of, the Underlying Index regardless of their investment merits. BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

Privatization Risk. China has begun a process of privatization of certain entities and industries. In some instances, investors in newly privatized entities have suffered losses due to the inability of the newly privatized entities to adjust quickly to a competitive environment or changing regulatory and legal standards or, in some cases, due to re-nationalization of such privatized entities. There is no assurance that such losses will not recur.

Reliance on Trading Partners Risk. Export growth continues to be a major driver of China’s rapid economic growth. To increase exports, China has pursued policies such as liberalizing trading rights and encouraging foreign companies to conduct manufacturing and assembly operations in China. Reduction in spending on Chinese products and services, institution of tariffs or other trade barriers or a downturn in any of the economies of China’s key trading partners may have an adverse impact on the companies in which the Fund invests.


U.S. Trading Partners Risk. The United States is a significant trading partner of or foreign investor in China. Decreasing U.S. imports, new trade regulations, changes in

the U.S. dollar exchange rate or a recession in the United States may have a material adverse effect on economies of the countries in which the Fund invests.

Risk of Investing in China. The Chinese economy is subject to a considerable degree of economic, political and social instability:

Political and Social Risk. The Chinese government is authoritarian and has periodically used force to suppress civil dissent. Disparities of wealth and the pace of economic liberalization may lead to social turmoil, violence and labor unrest. In addition, China continues to experience disagreements related to integration with Hong Kong and religious and nationalist disputes in Tibet and Xinjiang. There is also a greater risk involved in currency fluctuations, currency convertibility, interest rate fluctuations and higher rates of inflation as a result of internal social unrest or conflicts with other countries. Unanticipated political or social developments may result in sudden and significant investment losses. China’s growing income inequality and worsening environmental conditions also are factors that may affect the Chinese economy.

Government Control and Regulations. The Chinese government has implemented significant economic reforms in order to liberalize trade policy, promote foreign investment in the economy, reduce government control of the economy and develop market mechanisms. There can be no assurance these reforms will continue or that they will be effective. Despite recent reform and privatizations, significant regulation of investment and industry is still pervasive and the Chinese government may restrict foreign ownership of Chinese corporations and repatriation of assets. Chinese markets generally continue to experience inefficiency, volatility and pricing anomalies that may be connected to governmental influence, a lack of publicly-available information, and political and social instability.

Economic Risk. The Chinese economy has grown rapidly during the past several years and there is no assurance that this growth rate will be maintained. China may experience substantial rates of inflation or economic recessions, causing a negative effect on the economy and securities market. Delays in enterprise restructuring, slow development of well-functioning financial markets and widespread corruption have also hindered performance of the Chinese economy. China continues to receive substantial pressure from trading partners to liberalize official currency exchange rates.

Expropriation Risk. The Chinese government maintains a major role in economic policymaking and investing in China involves risk of loss due to expropriation, nationalization, or confiscation of assets and property or the imposition of restrictions on foreign investments and on repatriation of capital invested.

Hong Kong Political Risk. Hong Kong reverted to Chinese sovereignty on July 1, 1997 as a Special Administrative Region (SAR) of the People’s Republic of China (“PRC”) under the principle of “one country, two systems.” Although China is obligated to maintain the current capitalist economic and social system of Hong Kong through June 30, 2047, the continuation of economic and social freedoms enjoyed in Hong Kong is dependent on the government of China. Any attempt by China to tighten its control over Hong Kong’s political, economic, legal or social policies may result in an adverse effect on Hong Kong’s markets. In addition, the Hong Kong dollar trades at a fixed

exchange rate in relation to (or, is “pegged” to) the U.S. dollar, which has contributed to the growth and stability of the Hong Kong economy. However, it is uncertain how long the currency peg will continue or what effect the establishment of an alternative exchange rate system would have on the Hong Kong economy. Because the Fund’s NAV is denominated in U.S. dollars, the establishment of an alternative exchange rate system could result in a decline in the Fund’s NAV.

Securities Lending Risk. The Fund may engage in securities lending. Securities lending involves the risk that the Fund may lose money because the borrower of the Fund’s loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for the loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Security Risk. China has strained international relations with Taiwan, India, Russia and other neighbors due to territorial disputes, historical animosities and other defense concerns. Relations between China’s Han ethnic majority and other ethnic groups in China, including Tibetans and Uighurs, are also strained and have been marked by protests and violence. These situations may cause uncertainty in the Chinese market and may adversely affect the performance of the Chinese economy.

Telecommunications Sector Risk. The telecommunications sector is subject to extensive government regulation. The costs of complying with governmental regulations, delays or failure to receive required regulatory approvals, or the enactment of new adverse regulatory requirements may negatively affect the business of the telecommunications companies. Government actions around the world, specifically in the area of pre-marketing clearance of products and prices, can be arbitrary and unpredictable. Companies in the telecommunications sector may encounter distressed cash flows due to the need to commit substantial capital to meet increasing competition, particularly in formulating new products and services using new technology. Technological innovations may make the products and services of telecommunications companies obsolete.

Tracking Error Risk. Imperfect correlation between the Fund’s portfolio securities and those in the Underlying Index, rounding of prices, changes to the Underlying Index and regulatory requirements may cause tracking error, which is the divergence of the Fund’s performance from that of the Underlying Index. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Underlying Index does not. Because the Fund employs a representative sampling strategy, the Fund may experience tracking error to a greater extent than a fund that seeks to replicate an index.

Valuation Risk. Because non-U.S. exchanges may be open on days when the Fund does not price its shares, the value of the securities in the Fund’s portfolio may change on days when shareholders will not be able to purchase or sell the Fund’s shares. In addition, for purposes of calculating the Fund’s NAV, the value of assets denominated in non-U.S. currencies is converted into U.S. dollars using exchange rates deemed appropriate by BFA. This conversion may result in a difference between the prices used

to calculate the Fund’s NAV and the prices used by the Underlying Index, which, in turn, could result in a difference between the Fund’s performance and the performance of the Underlying Index.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

Basic Materials Sector Risk. Issuers in the basic materials sector could be adversely affected by commodity price volatility, exchange rates, import controls and increased competition. Production of industrial materials often exceeds demand as a result of over-building or economic downturns, leading to poor investment returns. Issuers in the basic materials sector are at risk for environmental damage and product liability claims and may be adversely affected by depletion of resources, delays in technical progress, labor relations and government regulations.

Portfolio Holdings Information

A description of the Trust’s policies and procedures with respect to the disclosure of the Fund’s portfolio securities is available in the Fund’s Statement of Additional Information (“SAI”). The top holdings of the Fund can be found at www.iShares.com. Fund fact sheets provide information regarding the Fund’s top holdings and may be requested by calling 1-800-iShares (1-800-474-2737).

Management

Investment Adviser. As investment adviser, BFA has overall responsibility for the general management and administration of the Trust. BFA provides an investment program for the Fund and manages the investment of the Fund’s assets. In managing the Fund, BFA may draw upon the research and expertise of its asset management affiliates with respect to certain portfolio securities. In seeking to achieve the Fund’s investment objective, BFA uses teams of portfolio managers, investment strategists and other investment specialists. This team approach brings together many disciplines and leverages BFA’s extensive resources.

Pursuant to the Investment Advisory Agreement between BFA and the Trust (entered into on behalf of the Fund), BFA is responsible for substantially all expenses of the Fund, except interest expenses, taxes, brokerage expenses, future distribution fees or expenses and extraordinary expenses.

For its investment advisory services to the Fund, BFA is entitled to receive a management fee from the Fund corresponding to the Fund’s allocable portion of an aggregate management fee based on the aggregate average daily net assets of the following iShares funds: iShares FTSE China 25 Index Fund and iShares FTSE China (HK Listed) Index Fund. The aggregate management fee is calculated as follows: 0.74% per annum of the aggregate net assets less than or equal to $6.0 billion, plus 0.67% per annum of the aggregate net assets over $6.0 billion up to and including $12.0 billion, plus 0.60% per annum of the aggregate net assets in excess of $12.0 billion.
As calculated on July 31, 2011, for its investment advisory services to the Fund, BFA is

entitled to receive a management fee from the Fund, based on a percentage of the Fund’s average daily net assets, at an annual rate of 0.72%.

BFA is located at 400 Howard Street, San Francisco, CA 94105. It is a wholly owned subsidiary of BTC, which in turn is indirectly wholly-owned by BlackRock, Inc. (“BlackRock”). As of September 30, 2011, BTC and its affiliates, including BFA and BlackRock, provided investment advisory services for assets in excess of $3.35 trillion. BFA, BTC, BlackRock Execution Services, BlackRock and their affiliates deal, trade and invest for their own accounts in the types of securities in which the Fund may also invest.

A discussion regarding the basis for the Trust’s Board of Trustees’ (the “Board”) approval of the Investment Advisory Agreement with BFA is available in the Fund’s annual report for the period ended July 31.

Portfolio Managers. Christopher Bliss, Rene Casis, Diane Hsiung and Greg Savage are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager is responsible for various functions related to portfolio management, including, but not limited to, investing cash inflows, coordinating with members of his or her portfolio management team to focus on certain asset classes, implementing investment strategy, researching and reviewing investment strategy and overseeing members of his or her portfolio management team that have more limited responsibilities.

Christopher Bliss has been employed by BFA (formerly, Barclays Global Fund Advisors (“BGFA”)) and BTC (formerly, Barclays Global Investors, N.A. (“BGI”)) as a senior portfolio manager since 2005. Prior to that, Mr. Bliss was a portfolio manager from 2004 to 2005 for BGFA and BGI. Mr. Bliss has been a Portfolio Manager of the Fund since 2011.

Rene Casis has been employed by BFA and BTC as a senior portfolio manager since 2009. From 2005 to 2009, Mr. Casis was a trader at Barclays Capital. Prior to that, Mr. Casis was a portfolio manager from 2000 to 2005 for BGFA and BGI. Mr. Casis has been a Portfolio Manager of the Fund since 2010.

Diane Hsiung has been employed by BFA and BTC as a senior portfolio manager since 2007. Prior to that, Ms. Hsiung was a portfolio manager from 2002 to 2006 for BGFA and BGI. Ms. Hsiung has been a Portfolio Manager of the Fund since 2008.

Greg Savage has been employed by BFA and BTC as a senior portfolio manager since 2006. Prior to that, Mr. Savage was a portfolio manager from 2001 to 2006 for BGFA and BGI. Mr. Savage has been a Portfolio Manager of the Fund since 2008.

The Fund’s SAI provides additional information about the Portfolio Managers’ compensation, other accounts managed by the Portfolio Managers and the Portfolio Managers’ ownership (if any) of shares in the Fund.

Administrator, Custodian and Transfer Agent. State Street Bank and Trust Company (“State Street”) is the administrator, custodian and transfer agent for the Fund.

Conflicts of Interest. BFA wants you to know that there are certain entities with which BFA has relationships that may give rise to conflicts of interest, or the

appearance of conflicts of interest. These entities include the following: BFA’s affiliates (including BlackRock and The PNC Financial Services Group, Inc., and each of their affiliates, directors, partners, trustees, managing members, officers and employees (collectively, the “Affiliates”)) and BlackRock’s significant shareholder, Barclays Bank PLC and its affiliates, including Barclays PLC (each, an “Entity” and together, the “Entities”).

The activities of BFA, the Affiliates and the Entities in the management of, or their interest in, their own accounts and other accounts they manage, may present conflicts of interest that could disadvantage the Fund and its shareholders. BFA and its Affiliates or the Entities provide investment management services to other funds and discretionary managed accounts that may follow an investment program similar to that of the Fund. BFA, its Affiliates and the Entities are involved worldwide with a broad spectrum of financial services and asset management activities and may engage in the ordinary course of business in activities in which their interests or the interests of their clients may conflict with those of the Fund. BFA, one or more of the Affiliates or the Entities acts, or may act, as an investor, investment banker, research provider, investment manager, financier, underwriter, advisor, market maker, trader, prime broker, lender, agent or principal, and have other direct and indirect interests, in securities, currencies and other instruments in which the Fund may directly or indirectly invest. Thus, it is likely that the Fund will have multiple business relationships with and will invest in, engage in transactions with, make voting decisions with respect to, or obtain services from, entities for which BFA, an Affiliate or an Entity performs or seeks to perform investment banking or other services.

BFA or one or more Affiliates or Entities may engage in proprietary trading and advise accounts and funds that have investment objectives similar to those of the Fund and/or that engage in and compete for transactions in the same types of securities, currencies and other instruments as the Fund, including in securities issued by other open-end and closed-end investment management companies, including investment companies that are affiliated with the Fund and BFA, to the extent permitted under the Investment Company Act of 1940, as amended (the “1940 Act”). The trading activities of BFA, these Affiliates and Entities are carried out without reference to positions held directly or indirectly by the Fund and may result in BFA, an Affiliate or an Entity having positions that are adverse to those of the Fund.

No Affiliate or Entity is under any obligation to share any investment opportunity, idea or strategy with the Fund. As a result, an Affiliate or an Entity may compete with the Fund for appropriate investment opportunities. As a result of this and several other factors, the results of the Fund’s investment activities may differ from those of an Affiliate or an Entity and of other accounts managed by an Affiliate or an Entity, and it is possible that the Fund could sustain losses during periods in which one or more Affiliates or Entities and other accounts achieve profits on their trading for proprietary or other accounts. The opposite result is also possible.

The Fund may, from time to time, enter into transactions in which BFA or an Affiliate’s or an Entity’s clients have an interest adverse to the Fund. Furthermore, transactions undertaken by Affiliate-advised clients may adversely impact the Fund. Transactions by

one or more Affiliate- or Entity-advised clients or BFA may have the effect of diluting or otherwise disadvantaging the values, prices or investment strategies of the Fund.

An Entity may maintain securities indices as part of its product offerings. Index-based funds seek to track the performance of securities indices and may use the name of the index in the fund name. Index providers, including the Entities, may be paid licensing fees for use of their indices or index names. Entities will not be obligated to license their indices to BFA and its Affiliates, and BFA and its Affiliates will not be assured that the terms of any index licensing agreement with the Entities will be as favorable as those terms offered to other index licensees.

The Fund’s activities may be limited because of regulatory restrictions applicable to one or more Affiliates or Entities, and/or their internal policies designed to comply with such restrictions. In addition, the Fund may invest in securities of companies with which an Affiliate or an Entity has or is trying to develop investment banking relationships or in which an Affiliate or an Entity has significant debt or equity investments. The Fund also may invest in securities of companies for which an Affiliate or an Entity provides or may some day provide research coverage. An Affiliate or an Entity may have business relationships with and purchase or distribute or sell services or products from or to distributors, consultants or others who recommend the Fund or who engage in transactions with or for the Fund, and may receive compensation for such services. The Fund may also make brokerage and other payments to Affiliates or Entities in connection with the Fund’s portfolio investment transactions.

Pursuant to a securities lending program approved by the Board, the Fund has retained an Affiliate of BFA to serve as the securities lending agent for the Fund to the extent that the Fund participates in the securities lending program. For these services, the lending agent may receive a fee from the Fund, including a fee based on the returns earned on the Fund’s investment of the cash received as collateral for any loaned securities. In addition, one or more Affiliates may be among the entities to which the Fund may lend its portfolio securities under the securities lending program.

The activities of BFA, the Affiliates or Entities may give rise to other conflicts of interest that could disadvantage the Fund and its shareholders. BFA has adopted policies and procedures designed to address these potential conflicts of interest. See the Fund’s SAI for further information.

Shares of the Fund may be acquired or redeemed directly from the Fund only in Creation Units or multiples thereof, as discussed in the Creations and Redemptions section of this Prospectus. Only an Authorized Participant (as defined in the Creations and Redemptions section) may engage in creation or redemption transactions directly with the Fund. Once created, shares of the Fund generally trade in the secondary market in amounts less than a Creation Unit.

Shares of the Fund are listed on a national securities exchange for trading during the trading day. Shares can be bought and sold throughout the trading day like shares of other publicly-traded companies. The Trust does not impose any minimum investment for shares of the Fund purchased on an exchange. The Fund’s shares trade under the trading symbol “FXI.”

Buying or selling Fund shares on an exchange involves two types of costs that may apply to all securities transactions. When buying or selling shares of the Fund through a broker, you will likely incur a brokerage commission or other charges determined by your broker. The commission is frequently a fixed amount and may be a significant proportional cost for investors seeking to buy or sell small amounts of shares. In addition, you may incur the cost of the “spread” – that is, any difference between the bid price and the ask price. The spread varies over time for shares of the Fund based on its trading volume and market liquidity, and is generally lower if the Fund has a lot of trading volume and market liquidity, and higher if the Fund has little trading volume and market liquidity.

The Board has adopted a policy of not monitoring for frequent purchases and redemptions of Fund shares (“frequent trading”) that appear to attempt to take advantage of a potential arbitrage opportunity presented by a lag between a change in the value of the Fund’s portfolio securities after the close of the primary markets for the Fund’s portfolio securities and the reflection of that change in the Fund’s NAV (“market timing”), because the Fund generally sells and redeems its shares directly through transactions that are in-kind and/or for cash, subject to the conditions described below under Creations and Redemptions. The Board has not adopted a policy of monitoring for other frequent trading activity because shares of the Fund are listed for trading on a national securities exchange.

The national securities exchange on which the Fund’s shares are listed is open for trading Monday through Friday and is closed on weekends and the following holidays: New Year’s Day, Martin Luther King, Jr. Day, Presidents’ Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day. The Fund’s primary listing exchange is NYSE Arca.

Section 12(d)(1) of the 1940 Act restricts investments by investment companies in the securities of other investment companies. Registered investment companies are permitted to invest in the Fund beyond the limits set forth in Section 12(d)(1), subject to certain terms and conditions set forth in SEC rules or in an SEC exemptive order issued to the Trust. In order for a registered investment company to invest in shares of the Fund beyond the limitations of Section 12(d)(1) pursuant to the exemptive relief obtained by the Trust, the registered investment company must enter into an agreement with the Trust.

Book Entry. Shares of the Fund are held in book-entry form, which means that no stock certificates are issued. The Depository Trust Company (“DTC”) or its nominee is the record owner of all outstanding shares of the Fund and is recognized as the owner of all shares for all purposes.

Investors owning shares of the Fund are beneficial owners as shown on the records of DTC or its participants. DTC serves as the securities depository for shares of the Fund.

DTC participants include securities brokers and dealers, banks, trust companies, clearing corporations and other institutions that directly or indirectly maintain a custodial relationship with DTC. As a beneficial owner of shares, you are not entitled to receive physical delivery of stock certificates or to have shares registered in your name, and you are not considered a registered owner of shares. Therefore, to exercise any right as an owner of shares, you must rely upon the procedures of DTC and its participants. These procedures are the same as those that apply to any other securities that you hold in book-entry or “street name” form.

Share Prices. The trading prices of the Fund’s shares in the secondary market generally differ from the Fund’s daily NAV and are affected by market forces such as supply and demand, economic conditions and other factors. Information regarding the intraday value of shares of the Fund, also known as the “indicative optimized portfolio value” (“IOPV”), is disseminated every 15 seconds throughout the trading day by the national securities exchange on which the Fund’s shares are listed or by market data vendors or other information providers. The IOPV is based on the current market value of the securities and/or cash required to be deposited in exchange for a Creation Unit. The IOPV does not necessarily reflect the precise composition of the current portfolio of securities held by the Fund at a particular point in time or the best possible valuation of the current portfolio. Therefore, the IOPV should not be viewed as a “real-time” update of the Fund’s NAV, which is computed only once a day. The IOPV is generally determined by using both current market quotations and/or price quotations obtained from broker-dealers that may trade in the portfolio securities held by the Fund. The quotations of certain Fund holdings may not be updated during U.S. trading hours if such holdings do not trade in the United States. The Fund is not involved in, or responsible for, the calculation or dissemination of the IOPV and makes no representation or warranty as to its accuracy.

Determination of Net Asset Value. The NAV of the Fund normally is determined once daily Monday through Friday, generally as of the regularly scheduled close of business of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m., Eastern time) on each day that the NYSE is open for trading, based on prices at the time of closing provided that (a) any Fund assets or liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers (as detailed below) and (b) U.S. fixed income assets may be valued as of the announced closing time for trading in fixed income instruments in a particular market or exchange. The NAV of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets held by the Fund, and its liabilities, are determined pursuant to valuation policies and procedures approved by the Board. The Fund’s assets and liabilities are valued primarily on the basis of market quotations.

Equity investments are valued at market value, which is generally determined using the last reported official closing price or last trading price on the exchange or market on which the security is primarily traded at the time of valuation.

The Fund invests in foreign securities. Foreign currency exchange rates are generally determined as of 4:00 p.m., London time. Foreign securities owned by the Fund may trade on weekends or other days when the Fund does not price its shares. As a result, the Fund’s NAV may change on days when Authorized Participants will not be able to purchase or redeem Fund shares.

Generally, trading in foreign securities, U.S. government securities, money market instruments and certain fixed-income securities is substantially completed each day at various times prior to the close of business on the NYSE. The values of such securities used in computing the NAV of the Fund are determined as of such times.

When market quotations are not readily available or are believed by BFA to be unreliable, the Fund’s investments are valued at fair value. Fair value determinations are made by BFA in accordance with policies and procedures approved by the Fund’s Board. BFA may conclude that a market quotation is not readily available or is unreliable if a security or other asset or liability does not have a price source due to its lack of liquidity, if a market quotation differs significantly from recent price quotations or otherwise no longer appears to reflect fair value, where the security or other asset or liability is thinly traded, or where there is a significant event subsequent to the most recent market quotation. A “significant event” is an event that, in the judgment of BFA, is likely to cause a material change to the closing market price of the asset or liability held by the Fund. Foreign securities whose values are affected by volatility that occurs in U.S. markets on a trading day after the close of foreign securities markets may be fair valued.

Fair value represents a good faith approximation of the value of an asset or liability. The fair value of an asset or liability held by the Fund is the amount the Fund might reasonably expect to receive from the current sale of that asset or the cost to extinguish that liability in an arm’s-length transaction. Valuing the Fund’s investments using fair value pricing will result in prices that may differ from current market valuations and that may not be the price at which those investments could have been sold during the period in which the particular fair values were used. Use of fair value prices and certain current market valuations could result in a difference between the prices used to calculate the Fund’s NAV and the prices used by the Underlying Index, which, in turn, could result in a difference between the Fund’s performance and the performance of the Underlying Index.

The value of assets or liabilities denominated in non-U.S. currencies will be converted into U.S. dollars using exchange rates deemed appropriate by BFA as investment adviser. Use of a rate different from the rate used by the Index Provider may adversely affect the Fund’s ability to track the Underlying Index.

Dividends and Distributions

General Policies. Dividends from net investment income, if any, generally are declared and paid semi-annually by the Fund. Distributions of net realized securities gains, if any, generally are declared and paid once a year, but the Trust may make distributions on a more frequent basis for the Fund. The Trust reserves the right to declare special distributions if, in its reasonable discretion, such action is necessary or advisable to preserve its status as a regulated investment company (“RIC”) or to avoid imposition of income or excise taxes on undistributed income or realized gains.

Dividends and other distributions on shares of the Fund are distributed on a pro rata basis to beneficial owners of such shares. Dividend payments are made through DTC participants and indirect participants to beneficial owners then of record with proceeds received from the Fund.

Dividend Reinvestment Service. No dividend reinvestment service is provided by the Trust. Broker-dealers may make available the DTC book-entry Dividend Reinvestment Service for use by beneficial owners of the Fund for reinvestment of their dividend distributions. Beneficial owners should contact their broker to determine the availability and costs of the service and the details of participation therein. Brokers may require beneficial owners to adhere to specific procedures and timetables. If this service is available and used, dividend distributions of both income and realized gains will be automatically reinvested in additional whole shares of the Fund purchased in the secondary market.

Taxes. As with any investment, you should consider how your investment in shares of the Fund will be taxed. The tax information in this Prospectus is provided as general information, based on current law. You should consult your own tax professional about the tax consequences of an investment in shares of the Fund.

Unless your investment in Fund shares is made through a tax-exempt entity or tax-deferred retirement account, such as an IRA, you need to be aware of the possible tax consequences when the Fund makes distributions or you sell Fund shares.

Taxes on Distributions. Distributions from the Fund’s net investment income (other than qualified dividend income), including distributions of income from securities lending and distributions out of the Fund’s net short-term capital gains, if any, are taxable to you as ordinary income. Distributions by the Fund of net long-term capital gains in excess of net short-term capital losses (capital gain dividends) are taxable to you as long-term capital gains, generally at a 15% tax rate (0% at certain income levels), regardless of how long you have held the Fund’s shares. Distributions by the Fund that qualify as qualified dividend income are taxable to you at long-term capital gain rates for taxable years beginning on or before December 31, 2012. The 15% and 0% tax rates expire for taxable years beginning after December 31, 2012. Maximum long-term capital gain income tax rates are scheduled to rise to 20% in 2013. Beginning in 2013, a 3.8% U.S. federal Medicare contribution tax will be imposed on “net investment income,” including interest, dividends, and capital gains, of U.S. individuals with income exceeding $200,000 (or $250,000 if married and filing jointly), and of estates and trusts.

Dividends will be qualified dividend income to you if they are attributable to qualified dividend income received by the Fund. Generally, qualified dividend income includes dividend income from taxable U.S. corporations and qualified non-U.S. corporations, provided that the Fund satisfies certain holding period requirements in respect of the stock of such corporations and has not hedged its position in the stock in certain ways. Substitute dividends received by the Fund with respect to dividends paid on securities lent out will not be qualified dividend income. For this purpose, a qualified non-U.S. corporation means any non-U.S. corporation that is eligible for benefits under a comprehensive income tax treaty with the United States, which includes an exchange of information program or if the stock with respect to which the dividend was paid is readily tradable on an established United States securities market. The term excludes a corporation that is a passive foreign investment company. Under current Internal Revenue Service (“IRS”) guidance, the United States has an appropriate comprehensive income tax treaty with China but not with Hong Kong, which is regarded as a separate jurisdiction for United States tax purposes.

Dividends received by the Fund from a real estate investment trust (“REIT”) or another RIC generally are qualified dividend income only to the extent the dividend distributions are made out of qualified dividend income received by such REIT or RIC. It is expected that dividends received by the Fund from a REIT and distributed to a shareholder generally will be taxable to the shareholder as ordinary income.

For a dividend to be treated as qualified dividend income, the dividend must be received with respect to a share of stock held without being hedged by the Fund, and with respect to a share of the Fund held without being hedged by you, for 61 days during the 121-day period beginning at the date which is 60 days before the date on which such share becomes ex-dividend with respect to such dividend or, in the case of certain preferred stock, 91 days during the 181-day period beginning 90 days before such date.

If your Fund shares are loaned out pursuant to a securities lending arrangement, you may lose the ability to use foreign tax credits passed through by the Fund or to treat Fund dividends paid while the shares are held by the borrower as qualified dividend income.

In general, your distributions are subject to U.S. federal income tax for the year when they are paid. Certain distributions paid in January, however, may be treated as paid on December 31 of the prior year.

If the Fund’s distributions exceed current and accumulated earnings and profits, all or a portion of the distributions made in the taxable year may be recharacterized as a return of capital to shareholders. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and result in a higher capital gain or lower capital loss when those shares on which the distribution was received are sold. Once a shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain, if the shareholder holds shares of the Fund as capital assets.

If you are neither a resident nor a citizen of the United States or if you are a non-U.S. entity, the Fund’s ordinary income dividends (which include distributions of net short-term capital gains) will generally be subject to a 30% U.S. withholding tax, unless a

lower treaty rate applies, provided that withholding tax will generally not apply to any gain or income realized by a non-U.S. shareholder in respect of any distributions of long-term capital gains or upon the sale or other disposition of shares of the Fund.

A 30% withholding tax will be imposed on dividends paid after December 31, 2013, and redemption proceeds paid after December 31, 2014, to (i) foreign financial institutions including non-U.S. investment funds unless they agree to collect and disclose to the IRS information regarding their direct and indirect U.S. account holders and (ii) certain other foreign entities, unless they certify certain information regarding their direct and indirect U.S. owners. To avoid withholding, foreign financial institutions will need to enter into agreements with the IRS that state that they will provide the IRS information, including the name, address and taxpayer identification number of direct and indirect U.S. account holders, comply with due diligence procedures with respect to the identification of U.S. accounts, report to the IRS certain information with respect to U.S. accounts maintained, agree to withhold tax on certain payments made to non-compliant foreign financial institutions or to account holders who fail to provide the required information, and determine certain other information as to their account holders. Other foreign entities will need to provide the name, address, and taxpayer identification number of each substantial U.S. owner or certifications of no substantial U.S. ownership unless certain exceptions apply.

Dividends, interest and capital gains earned by the Fund with respect to non-U.S. securities may give rise to withholding and other taxes imposed by non-U.S. countries. Tax conventions between certain countries and the United States may reduce or eliminate such taxes. If more than 50% of the total assets of the Fund at the close of a year consists of non-U.S. stocks or securities, the Fund may “pass through” to you certain non-U.S. income taxes (including withholding taxes) paid by the Fund. This means that you would be considered to have received as an additional dividend your share of such non-U.S. taxes, but you may be entitled to either a corresponding tax deduction in calculating your taxable income, or, subject to certain limitations, a credit in calculating your U.S. federal income tax.

For purposes of foreign tax credits for U.S. shareholders of the Fund, foreign capital gains taxes may not produce associated foreign source income, thereby limiting a U.S. person’s ability to use such credits.

If you are a resident or a citizen of the United States, by law, back-up withholding will apply to your distributions and proceeds if you have not provided a taxpayer identification number or social security number and made other required certifications.

Taxes When Shares are Sold. Currently, any capital gain or loss realized upon a sale of Fund shares is generally treated as a long-term gain or loss if the shares have been held for more than one year. Any capital gain or loss realized upon a sale of Fund shares held for one year or less is generally treated as short-term gain or loss, except that any capital loss on the sale of shares held for six months or less is treated as long-term capital loss to the extent that capital gain dividends were paid with respect to such shares. Beginning in 2013, any such capital gains, including from sales of Fund shares or from capital gain dividends, will be included in “net investment income” for purposes of the 3.8% U.S. federal Medicare contribution tax mentioned above.

The foregoing discussion summarizes some of the consequences under current U.S. federal tax law of an investment in the Fund. It is not a substitute for personal tax advice. You may also be subject to state and local taxation on Fund distributions and sales of shares. Consult your personal tax adviser about the potential tax consequences of an investment in shares of the Fund under all applicable tax laws.

Chinese Tax Disclosure. Although the People’s Republic of China enactment of the Enterprise Income Tax Law, effective January 1, 2008, provided a 10% withholding tax upon non-residents with respect to capital gains, significant uncertainties remain. Such uncertainties may result in capital gains imposed upon the Fund relative to companies headquartered, managed or listed in China. While the application and enforcement of this law to the Fund remains subject to clarification, to the extent that such taxes are imposed on any capital gains of the Fund relative to companies headquartered, managed or listed in China, the Fund’s NAV or returns may be adversely impacted.

Creations and Redemptions. Prior to trading in the secondary market, shares of the Fund are “created” at NAV by market makers, large investors and institutions only in block-size Creation Units of 150,000 shares or multiples thereof. Each “creator” or “Authorized Participant” enters into an authorized participant agreement with the Fund’s distributor, SEI Investments Distribution Co. (the “Distributor”). Only an Authorized Participant may create or redeem Creation Units directly with the Fund. A creation transaction, which is subject to acceptance by the transfer agent, generally takes place when an Authorized Participant deposits into the Fund a designated portfolio of securities and a specified amount of cash approximating the holdings of the Fund in exchange for a specified number of Creation Units. To the extent practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund.

Similarly, shares can be redeemed only in Creation Units, generally for a designated portfolio of securities and a specified amount of cash held by the Fund (“Fund Securities”). Except when aggregated in Creation Units, shares are not redeemable by the Fund. The prices at which creations and redemptions occur are based on the next calculation of NAV after an order is received in a form described in the authorized participant agreement.

The Fund intends to comply with the U.S. federal securities laws in accepting securities for deposit and satisfying redemptions with redemption securities by, among other means, assuring that any securities accepted for deposit and any securities used to satisfy redemption requests will be sold in transactions that would be exempt from registration under the Securities Act of 1933, as amended (the “1933 Act”). Further, an Authorized Participant that is not a “qualified institutional buyer,” as such term is defined under Rule 144A of the 1933 Act, will not be able to receive Fund Securities that are restricted securities eligible for resale under Rule 144A.

Creations and redemptions must be made through a firm that is either a member of the Continuous Net Settlement System of the National Securities Clearing Corporation or a DTC participant and has executed an agreement with the Distributor with respect to creations and redemptions of Creation Unit aggregations. Information about the procedures regarding creation and redemption of Creation Units (including the cut-off times for receipt of creation and redemption orders) is included in the Fund’s SAI.

Because new shares may be created and issued on an ongoing basis, at any point during the life of the Fund a “distribution,” as such term is used in the 1933 Act, may be occurring. Broker-dealers and other persons are cautioned that some activities on their part may, depending on the circumstances, result in their being deemed participants in a distribution in a manner that could render them statutory underwriters and subject to the prospectus delivery and liability provisions of the 1933 Act. Any determination of whether one is an underwriter must take into account all the relevant facts and circumstances of each particular case.

Broker-dealers should also note that dealers who are not “underwriters” but are participating in a distribution (as contrasted to ordinary secondary transactions), and thus dealing with shares that are part of an “unsold allotment” within the meaning of Section 4(3)(C) of the 1933 Act, would be unable to take advantage of the prospectus delivery exemption provided by Section 4(3) of the 1933 Act. For delivery of prospectuses to exchange members, the prospectus delivery mechanism of Rule 153 under the 1933 Act is available only with respect to transactions on a national securities exchange.

Costs Associated with Creations and Redemptions. Authorized Participants are charged standard creation and redemption transaction fees to offset transfer and other transaction costs associated with the issuance and redemption of Creation Units. The standard creation and redemption transaction fees are set forth in the table below. The standard creation transaction fee is charged to the Authorized Participant on the day such Authorized Participant creates a Creation Unit, and is the same regardless of the number of Creation Units purchased by the Authorized Participant on the applicable business day. Similarly, the standard redemption transaction fee is charged to the Authorized Participant on the day such Authorized Participant redeems a Creation Unit, and is the same regardless of the number of Creation Units redeemed by the Authorized Participant on the applicable business day. Creations and redemptions for cash (when cash creations and redemptions (in whole or in part) are available or specified) are also subject to an additional charge (up to the maximum amounts shown in the table below). This charge is intended to compensate for brokerage, tax, foreign exchange, execution, market impact and other costs and expenses related to cash transactions. Investors who use the services of a broker or other financial intermediary may pay fees for such services.

The following table shows, as of September 30, 2011, the approximate value of one Creation Unit, standard fees and maximum additional charges for creations and redemptions (as described above):

Householding. Householding is an option available to certain Fund investors. Householding is a method of delivery, based on the preference of the individual investor, in which a single copy of certain shareholder documents can be delivered to investors who share the same address, even if their accounts are registered under different names. Please contact your broker-dealer if you are interested in enrolling in householding and receiving a single copy of prospectuses and other shareholder documents, or if you are currently enrolled in householding and wish to change your householding status.

Distribution

The Distributor distributes Creation Units for the Fund on an agency basis. The Distributor does not maintain a secondary market in shares of the Fund. The Distributor has no role in determining the policies of the Fund or the securities that are purchased or sold by the Fund. The Distributor’s principal address is One Freedom Valley Drive, Oaks, PA 19456.

In addition, BFA or its Affiliates make payments to broker-dealers, banks or other financial intermediaries (together, “intermediaries”) related to marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems, or their making shares of the Fund and certain other iShares funds available to their customers. Such payments, which may be significant to the intermediary, are not made by the Fund. Rather, such payments are made by BFA or its Affiliates from their own resources, which come directly or indirectly in part from fees paid by the iShares funds complex. Payments of this type are sometimes referred to as revenue-sharing payments. A financial intermediary may make decisions about which investment options it recommends or makes available, or the level of services provided, to its customers based on the revenue-sharing payments it is eligible to receive. Therefore, such payments to an intermediary create conflicts of interest between the intermediary and its customers and may cause the intermediary to recommend the Fund or other iShares funds over another investment. More information regarding these payments is contained in the Fund’s SAI. Please contact your salesperson or other investment professional for more information regarding any such payments his or her firm may receive from BFA or its Affiliates.

Financial Highlights

The financial highlights table is intended to help investors understand the Fund’s financial performance for the past five years. Certain information reflects financial results for a single share of the Fund. The total returns in the table represent the rate that an investor would have earned (or lost) on an investment in the Fund, assuming reinvestment of all dividends and distributions. This information has been audited by PricewaterhouseCoopers LLP, whose report is included, along with the Fund’s financial statements, in the Fund’s Annual Report (available upon request).

Supplemental Information

I. Premium/Discount Information

The table that follows presents information about the differences between the daily market price on secondary markets for shares of the Fund and the Fund’s NAV. NAV is the price at which the Fund issues and redeems shares. It is calculated in accordance with the standard formula for valuing mutual fund shares. The price used to calculate market returns (“Market Price”) of the Fund generally is determined using the midpoint between the highest bid and the lowest offer on the primary securities exchange on which shares of the Fund are listed for trading, as of the time that the Fund’s NAV is calculated. The Fund’s Market Price may be at, above or below its NAV. The NAV of the Fund will fluctuate with changes in the value of its portfolio holdings. The Market Price of the Fund will fluctuate in accordance with changes in its NAV, as well as market supply and demand.

Premiums or discounts are the differences (expressed as a percentage) between the NAV and Market Price of the Fund on a given day, generally at the time the NAV is calculated. A premium is the amount that the Fund is trading above the reported NAV, expressed as a percentage of the NAV. A discount is the amount that the Fund is trading below the reported NAV, expressed as a percentage of the NAV.

The following information shows the frequency of distributions of premiums and discounts for the Fund for each full calendar quarter of 2010 through September 30, 2011.

Each line in the table shows the number of trading days in which the Fund traded within the premium/discount range indicated. The number of trading days in each premium/discount range is also shown as a percentage of the total number of trading days in the period covered by the table. All data presented here represents past performance, which cannot be used to predict future results.

Less than -4.5% 1 0.23
   441 100.00%

II. Total Return Information

The tables that follow present information about the total returns of the Fund and the Underlying Index as of the fiscal year ended July 31, 2011.

“Average Annual Total Returns” represent the average annual change in value of an investment over the periods indicated. “Cumulative Total Returns” represent the total change in value of an investment over the periods indicated.

The Fund’s NAV is the value of one share of the Fund as calculated in accordance with the standard formula for valuing mutual fund shares. The NAV return is based on the NAV of the Fund and the market return is based on the Market Price of the Fund. Market Price is determined by using the midpoint between the highest bid and the lowest offer on the primary stock exchange on which shares of the Fund are listed for trading, as of the time that the Fund’s NAV is calculated. Since shares of the Fund did not trade in the secondary market until after the Fund’s inception, for the period from inception to the first day of secondary market trading in shares of the Fund, the NAV of the Fund is used as a proxy for the Market Price to calculate market returns. Market and NAV returns assume that dividends and capital gain distributions have been reinvested in the Fund at Market Price and NAV, respectively.

An index is a statistical composite that tracks a specified financial market or sector. Unlike the Fund, the Underlying Index does not actually hold a portfolio of securities and therefore does not incur the expenses incurred by the Fund. These expenses negatively impact the performance of the Fund. Also, market returns do not include brokerage commissions that may be payable on secondary market transactions. If brokerage commissions were included, market returns would be lower. The returns shown in the following tables do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption or sale of Fund shares. The investment return and principal value of shares of the Fund will vary with changes in market conditions. Shares of the Fund may be worth more or less than their original cost when they are redeemed or sold in the market. The Fund’s past performance is no guarantee of future results.

Fund Overview

iSHARES® MSCI ACWI ex US CONSUMER DISCRETIONARY SECTOR INDEX FUND

Ticker: AXDI Stock Exchange: NYSE Arca

Investment Objective

The iShares MSCI ACWI ex US Consumer Discretionary Sector Index Fund (the “Fund”) seeks investment results that correspond generally to the price and yield performance, before fees and expenses, of the MSCI All Country World ex USA Consumer Discretionary Index (the “Underlying Index”).

Fees and Expenses

The following table describes the fees and expenses that you will incur if you own shares of the Fund. The investment advisory agreement between iShares Trust (the “Trust”) and BlackRock Fund Advisors (“BFA”) (the “Investment Advisory Agreement”) provides that BFA will pay all operating expenses of the Fund, except interest expenses, taxes, brokerage expenses, future distribution fees or expenses, and extraordinary expenses.

You may also incur usual and customary brokerage commissions when buying or selling shares of the Fund, which are not reflected in the example that follows:

Annual Fund Operating Expenses

Operating
Expenses
0.48% None None 0.48%

Example. This Example is intended to help you compare the cost of owning shares of the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

Portfolio Turnover. The Fund may pay transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 7% of the average value of its portfolio.

Principal Investment Strategies

The Underlying Index is a free float-adjusted market capitalization-weighted index designed to measure the combined equity market performance of the consumer discretionary sector of developed and emerging markets countries, excluding the United States. Component securities include those of manufacturers of automobiles and automotive components, consumer durables and apparel, consumer services, media producers and retailer companies. As of September 30, 2011, the Underlying Index consisted of companies in the following countries or regions: Australia, Austria, Belgium, Brazil, Canada, Chile, China, Colombia, the Czech Republic, Denmark, Egypt, Finland, France, Germany, Greece, Hong Kong, Hungary, India, Indonesia, Italy, Ireland, Israel, Japan, Malaysia, Mexico, Morocco, the Netherlands, New Zealand, Norway, Peru, the Philippines, Poland, Portugal, Russia, Singapore, South Africa, South Korea, Spain, Sweden, Switzerland, Taiwan, Thailand, Turkey and the United Kingdom (together, the “ACWI ex US consumer discretionary sector countries”). As of September 30, 2011, the Underlying Index was comprised of 225 securities.

BFA uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to “beat” the index it tracks and does not seek temporary defensive positions when markets decline or appear overvalued.

Indexing may eliminate the chance that the Fund will substantially outperform the Underlying Index but also may reduce some of the risks of active management, such as poor security selection. Indexing seeks to achieve lower costs and better after-tax performance by keeping portfolio turnover low in comparison to actively managed investment companies.

BFA uses a representative sampling indexing strategy to manage the Fund. “Representative sampling” is an indexing strategy that involves investing in a representative sample of securities that collectively has an investment profile similar to the Underlying Index. The securities selected are expected to have, in the aggregate, investment characteristics (based on factors such as market capitalization and industry weightings), fundamental characteristics (such as return variability and yield) and liquidity measures similar to those of the Underlying Index. The Fund may or may not hold all of the securities in the Underlying Index.

The Fund generally invests at least 80% of its assets in securities of the Underlying Index or in depositary receipts representing securities of the Underlying Index. The Fund may invest the remainder of its assets in securities

S-2   


Table Of Contents



not included in the Underlying Index, but which BFA believes will help the Fund track the Underlying Index and in other investments including futures contracts, options on futures contracts, options and swaps related to the Underlying Index, as well as cash and cash equivalents, including shares of money market funds advised by BFA or its affiliates.

The Fund may lend securities representing up to one-third of the value of the Fund’s total assets (including the value of the collateral received).

The Underlying Index is sponsored by an organization (the “Index Provider”) that is independent of the Fund and BFA. The Index Provider determines the composition and relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index. The Fund’s Index Provider is MSCI Inc. (“MSCI”).

Industry Concentration Policy. The Fund will concentrate its investments (i.e., hold 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. For purposes of this limitation, securities of the U.S. government (including its agencies and instrumentalities) and repurchase agreements collateralized by U.S. government securities are not considered to be issued by members of any industry.

Summary of Principal Risks

As with any investment, you could lose all or part of your investment in the Fund, and the Fund’s performance could trail that of other investments. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund’s net asset value per share (“NAV”), trading price, yield, total return and ability to meet its investment objective.

Asset Class Risk. Securities in the Underlying Index or in the Fund’s portfolio may underperform in comparison to the general securities markets or other asset classes.

Automotive Industry Risk. The automotive industry can be highly cyclical and companies in the automotive industry may suffer periodic losses. Among other things, the automotive industry is susceptible to labor disputes, economic downturns and increase in component and material prices. As a result, such risks, among others, may adversely affect the value of the Fund’s investments.

Concentration Risk. To the extent that the Fund’s investments are concentrated in a particular issuer, region, country, market, industry or asset class, the Fund may be susceptible to loss due to adverse occurrences affecting that issuer, region, country, market, industry or asset class.

Consumer Discretionary Sector Risk. The consumer discretionary sector may be affected by changes in domestic and international economies, exchange and interest rates, competition, consumers’ disposable income and consumer preferences, social trends and marketing campaigns.

Consumer Durables and Apparel Sector Risk. The consumer durables and apparel sector includes companies involved in the design, production, or distribution of household durables, leisure equipment and goods, textiles,

S-3   


Table Of Contents



luxury goods or apparel, each of which may be affected by changes in domestic and international economies, consumer confidence, disposable household income and spending, and consumer tastes and preferences. Companies in the consumer durables and apparel sector face intense competition.

Consumer Goods Sector Risk. The consumer goods sector may be affected by changes in social trends and consumer demands. Many consumer goods are sold internationally and such companies are subject to market conditions in other countries and regions.

Currency Risk. Because the Fund’s NAV is determined in U.S. dollars, the Fund’s NAV could decline if the currency of a non-U.S. market in which the Fund invests depreciates against the U.S. dollar.

Custody Risk. Less developed markets are more likely to experience problems with the clearing and settling of trades and the holding of securities by local banks, agents and depositories.

Emerging Markets Risk. The Fund’s investments in emerging markets may be subject to a greater risk of loss than investments in more developed markets. Emerging markets may be more likely to experience inflation risk, political turmoil and rapid changes in economic conditions than more developed markets. Emerging markets often have less uniformity in accounting and reporting requirements, unreliable securities valuation and greater risk associated with custody of securities.

Equity Securities Risk. Equity securities are subject to changes in value and their values may be more volatile than other asset classes.

Geographic Risk. A natural or other disaster could occur in a geographic region in which the Fund invests, which could affect the economy or particular business operations of companies in the specific geographic region, causing an adverse impact on the Fund’s investments in the affected region.

Issuer Risk. Fund performance depends on the performance of individual securities to which the Fund has exposure. Changes to the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA’s investment management strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares, losses from trading in secondary markets, periods of high volatility and disruption in the creation/redemption process of the Fund. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV.

Mid-Capitalization Companies Risk. The Fund may invest in the securities of mid-capitalization companies. Compared to large-capitalization companies, mid-capitalization companies may be less stable and more susceptible to adverse developments and their securities may be more volatile and less liquid.



S-4   


Table Of Contents



Non-Diversification Risk. The Fund may invest a large percentage of its assets in securities issued by or representing a small number of issuers. As a result, the Fund’s performance may depend on the performance of a small number of issuers.

Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers are subject to the risks associated with investing in those non-U.S. markets, such as heightened risks of inflation or nationalization. The Fund may lose money due to political, economic and geographic events affecting a non-U.S. issuer or market. The Fund is specifically exposed to Asian Economic Risk and European Economic Risk.

Passive Investment Risk. The Fund is not actively managed and BFA does not attempt to take defensive positions under any market conditions, including declining markets.

Privatization Risk. Some countries in which the Fund invests have begun a process of privatizing certain entities and industries. Privatized entities may lose money or be re-nationalized.

Reliance on Trading Partners Risk. The Fund invests in countries whose economies are heavily dependent upon trading with key partners. Any reduction in this trading may have an adverse impact on the Fund’s investments. Through its trading partners, the Fund is particularly exposed to U.S. Trading Partner Risk.

Retail Sector Risk. The retail sector may be affected by changes in domestic and international economies, consumer confidence, disposable household income and spending, and consumer tastes and preferences. Companies in the retail sector face intense competition.

Risk of Investing in Japan. The Japanese economy may be subject to considerable degrees of economic, political and social instability, which could have a negative impact on Japanese securities.

Securities Lending Risk. The Fund may engage in securities lending. Securities lending involves the risk that the Fund may lose money because the borrower of the Fund’s loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Security Risk. Some countries and regions in which the Fund invests have experienced security concerns. Incidents involving a country’s or region’s security may cause uncertainty in these markets and may adversely affect their economies and the Fund’s investments.

Structural Risk. The countries in which the Fund invests may be subject to considerable degrees of economic, political and social instability.

Tracking Error Risk. The performance of the Fund may diverge from that of the Underlying Index. Because the Fund employs a representative sampling strategy, the Fund may experience tracking error to a greater extent than a fund that seeks to replicate an index.

Valuation Risk. The value of the securities in the Fund’s portfolio may change on days when shareholders will

not be able to purchase or sell the Fund’s shares.

Performance Information

As of the date of the Fund’s prospectus (the “Prospectus”), the Fund has been in operation for less than one full calendar year and therefore does not report its performance information.

Management

Investment Adviser. BlackRock Fund Advisors.

Portfolio Managers. Rene Casis, Diane Hsiung and Greg Savage (the “Portfolio Managers”) are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager supervises a portfolio management team. Mr. Casis has been a Portfolio Manager of the Fund since 2010. Ms. Hsiung and Mr. Savage have been Portfolio Managers of the Fund since inception.

Purchase and Sale of Fund Shares

The Fund is an exchange-traded fund (commonly referred to as an “ETF”). Individual Fund shares may only be purchased and sold on a national securities exchange through a broker-dealer. The price of Fund shares is based on market price, and because ETF shares trade at market prices rather than NAV, shares may trade at a price greater than NAV (a premium) or less than NAV (a discount). The Fund will only issue or redeem shares that have been aggregated into blocks of 50,000 shares or multiples thereof (“Creation Units”) to authorized participants who have entered into agreements with the Fund’s distributor. The Fund generally will issue or redeem Creation Units in return for a designated portfolio of securities (and an amount of cash) that the Fund specifies each day.

Tax Information

The Fund intends to make distributions that may be taxable to you as ordinary income or capital gains, unless you are investing through a tax-deferred arrangement such as a 401(k) plan or an individual retirement account (“IRA”).

Payments to Broker-Dealers and other Financial Intermediaries

If you purchase shares of the Fund through a broker-dealer or other financial intermediary (such as a bank), BFA or other related companies may pay the intermediary for marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems or other services related to the sale or promotion of the Fund. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.

More Information About the Fund

This Prospectus contains important information about investing in the Fund. Please read this Prospectus carefully before you make any investment decisions. Additional information regarding the Fund is available at www.iShares.com.

BFA is the investment adviser to the Fund. Shares of the Fund are listed for trading on NYSE Arca, Inc. (“NYSE Arca”). The market price for a share of the Fund may be different from the Fund’s most recent NAV.

ETFs are funds that trade like other publicly-traded securities. The Fund is designed to track an index. Similar to shares of an index mutual fund, each share of the Fund represents a partial ownership in an underlying portfolio of securities intended to track a market index. Unlike shares of a mutual fund, which can be bought and redeemed from the issuing fund by all shareholders at a price based on NAV, shares of the Fund may be purchased or redeemed directly from the Fund at NAV solely by authorized participants. Also unlike shares of a mutual fund, shares of the Fund are listed on a national securities exchange and trade in the secondary market at market prices that change throughout the day.

The Fund invests in a particular segment of the securities markets and seeks to track the performance of a securities index that generally is not representative of the market as a whole. The Fund is designed to be used as part of broader asset allocation strategies. Accordingly, an investment in the Fund should not constitute a complete investment program.

An index is a theoretical financial calculation while the Fund is an actual investment portfolio. The performance of the Fund and the Underlying Index may vary due to transaction costs, non-U.S. currency valuations, asset valuations, corporate actions (such as mergers and spin-offs), timing variances and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions (such as diversification requirements) that apply to the Fund but not to the Underlying Index or to the use of representative sampling. “Tracking error” is the difference between the performance (return) of the Fund’s portfolio and that of the Underlying Index. BFA expects that, over time, the Fund’s tracking error will not exceed 5%. Because the Fund uses a representative sampling indexing strategy, it can be expected to have a larger tracking error than if it used a replication indexing strategy. “Replication” is an indexing strategy in which a fund invests in substantially all of the securities in its underlying index in approximately the same proportions as in the underlying index.

An investment in the Fund is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, BFA or any of its affiliates.

The Fund’s investment objective and the Underlying Index may be changed without shareholder approval.

A Further Discussion of Principal Risks

The Fund is subject to various risks, including the principal risks noted below, any of which may adversely affect the Fund’s NAV, trading price, yield, total return and ability to meet its investment objective. You could lose all or part of your investment in the Fund, and the Fund could underperform other investments.

Asian Economic Risk. Certain Asian economies have experienced over-extension of credit, currency devaluations and restrictions, high unemployment, high inflation, decreased exports and economic recessions. Economic events in any one Asian country may have a significant economic effect on the entire Asian region, as well as on major trading partners outside Asia, and any adverse event in the Asian markets may have a significant adverse effect on some or all of the ACWI ex US consumer discretionary sector countries.

Asset Class Risk. The securities in the Underlying Index or in the Fund’s portfolio may underperform the returns of other securities or indexes that track other countries, groups of countries, regions, industries, groups of industries, markets, asset classes or sectors. Various types of securities or indexes tend to experience cycles of outperformance and underperformance in comparison to the general securities markets.

Automotive Industry Risk. Investments in the automotive industry involve risks that are specific to the automotive industry, including economic downturns, changing consumer tastes, product obsolescence, and increases in component or material prices. The automotive industry can be highly cyclical and may be significantly affected by labor disputes. As a result, such risks, among others, may adversely affect the value of the Fund’s investments.

Concentration Risk. To the extent that the Fund’s portfolio reflects the Underlying Index’s concentration in the securities of a particular issuer or issuers in a particular country, group of countries, region, market, industry, group of industries, sector or asset class, the Fund may be adversely affected by the performance of those securities, may be subject to increased price volatility and may be more susceptible to adverse economic, market, political or regulatory occurrences affecting that issuer, country, group of countries, region, market, industry, group of industries, sector or asset class.

Consumer Discretionary Sector Risk. The success of consumer product manufacturers and retailers is tied closely to the performance of domestic and international economies, interest rates, exchange rates, competition, consumer confidence, changes in demographics and consumer preferences. Companies in the consumer discretionary sector depend heavily on disposable household income and consumer spending, and may be strongly affected by social trends and marketing campaigns. These companies may be subject to severe competition, which may have an adverse impact on their profitability.

Consumer Durables and Apparel Sector Risk. The consumer durables and apparel sector includes companies involved in the design, production, or distribution of household durables, leisure equipment and goods, textiles, luxury goods or apparel, each of which may be affected by changes in domestic and international economies,

consumer confidence, disposable household income and spending, and consumer tastes and preferences. Companies in the consumer durables and apparel sector face intense competition, which may have an adverse effect on their profitability. The success of companies in the consumer durables and apparel sector may be strongly affected by social trends and marketing campaigns. Companies in the consumer durables and apparel sector may be dependent on outside financing, which may be difficult to obtain. Many of these companies are dependent on third party suppliers and distribution systems. Consumer durables and apparel companies may be unable to protect their intellectual property rights or may be liable for infringing the intellectual property rights of others. In addition, goods in the consumer durables and apparel sector may face by the risk of rapid obsolescence.

Consumer Goods Sector Risk. The consumer goods sector may be strongly affected by social trends, marketing campaigns and other factors affecting consumer demand. Governmental regulation affecting the use of various food additives may affect the profitability of certain companies represented in the Underlying Index. In addition, tobacco companies may be adversely affected by new laws, regulations and litigation. Many consumer goods in the United States may also be marketed globally, and such consumer goods companies may be affected by the demand and market conditions in non-U.S. countries.

Currency Risk. Because the Fund’s NAV is determined on the basis of the U.S. dollar, investors may lose money if the currency of a non-U.S. market in which the Fund invests depreciates against the U.S. dollar, even if the local currency value of the Fund’s holdings in that market increases.



Custody Risk. Custody risk refers to the risks inherent in the process of clearing and settling trades and the holding of securities by local banks, agents and depositories. Low trading volumes and volatile prices in less developed markets may make trades harder to complete and settle, and governments or trade groups may compel local agents to hold securities in designated depositories that are not subject to independent evaluation. Local agents are held only to the standards of care of their local markets. In general, the less developed a country’s securities market is, the greater the likelihood of custody problems.

Emerging Markets Risk. Investments in emerging markets are subject to a greater risk of loss than investments in more developed markets. This is due to, among other things, the potential for greater market volatility, lower trading volume, inflation, political and economic instability, greater risk of a market shutdown and more governmental limitations on foreign investments than typically found in more developed markets. In addition, emerging markets often have less uniformity in accounting and reporting requirements, unreliable securities valuation and greater risks associated with custody of securities.

Equity Securities Risk. The Fund invests in equity securities, which are subject to changes in value that may be attributable to market perception of a particular issuer or to general stock market fluctuations that affect all issuers. Investments in equity securities may be more volatile than investments in other asset classes.

European Economic Risk. The Economic and Monetary Union of the European Union (the “EU”) requires member countries to comply with restrictions on inflation rates, deficits, interest rates, debt levels and fiscal and monetary controls, each of which may significantly affect every country in Europe. Decreasing imports or exports, changes in governmental or EU regulations on trade, changes in the exchange rate of the euro, the default or threat of default by an EU member country on its sovereign debt, and/or an economic recession in an EU member country may have a significant adverse effect on the economies of EU member countries and their trading partners, including some or all of the ACWI ex US consumer discretionary sector countries. The European financial markets have recently experienced volatility and have been adversely affected by concerns about economic downturns, credit rating downgrades, rising government debt levels and possible default on or restructuring of government debt in several European countries, including Greece, Ireland, Italy, Portugal and Spain. A default or debt restructuring by any European country would adversely impact holders of that country’s debt, and sellers of credit default swaps linked to that country’s creditworthiness, which may be located in countries other than those listed in the previous sentence. These events have adversely affected the value and exchange rate of the euro and may continue to significantly affect the economies of every country in Europe, including EU member countries that do not use the euro and non-EU member countries.

Geographic Risk. Some markets in which the Fund invests are located in parts of the world that have historically been prone to natural disasters, such as earthquakes, volcanoes, droughts, floods, hurricanes and tsunamis, and are economically sensitive to environmental events. Any natural or other disaster could have a significant adverse impact on the economies of these geographic areas, causing an adverse impact on the Fund’s investments in the affected region.

Issuer Risk. The performance of the Fund depends on the performance of individual securities to which the Fund has exposure. Any issuer of these securities may perform poorly, causing the value of its securities to decline. Poor performance may be caused by poor management decisions, competitive pressures, changes in technology, expiration of patent protection, disruptions in supply, labor problems or shortages, corporate restructurings, fraudulent disclosures or other factors. Issuers may, in times of distress or at their own discretion, decide to reduce or eliminate dividends, which may also cause their stock prices to decline.

Management Risk. The Fund may not fully replicate the Underlying Index and may hold securities not included in the Underlying Index. As a result, the Fund is subject to the risk that BFA’s investment management strategy, the implementation of which is subject to a number of constraints, may not produce the intended results.

Market Risk. The Fund could lose money due to short-term market movements and over longer periods during market downturns. Securities may decline in value due to factors affecting securities markets generally or particular industries represented in the markets. The value of a security may decline due to general market conditions, economic trends or events that are not specifically related to the issuer of the security or to factors that affect a particular industry or industries. During a general downturn in the securities markets, multiple asset classes may be negatively affected.

Market Trading Risk

Absence of Active Market. Although shares of the Fund are listed for trading on one or more stock exchanges, there can be no assurance that an active trading market for such shares will develop or be maintained.

Risk of Secondary Listings. The Fund’s shares may be listed or traded on U.S. and non-U.S. stock exchanges other than the U.S. stock exchange where the Fund’s primary listing is maintained. There can be no assurance that the Fund’s shares will continue to trade on any such stock exchange or in any market or that the Fund’s shares will continue to meet the requirements for listing or trading on any exchange or in any market. The Fund’s shares may be less actively traded in certain markets than others, and investors are subject to the execution and settlement risks and market standards of the market where they or their broker direct their trades for execution. Certain information available to investors who trade Fund shares on a U.S. stock exchange during regular U.S. market hours may not be available to investors who trade in other markets, which may result in secondary market prices in such markets being less efficient.

Secondary Market Trading Risk. Shares of the Fund may trade in the secondary market at times when the Fund does not accept orders to purchase or redeem shares. At such times, shares may trade in the secondary market with more significant premiums or discounts than might be experienced at times when the Fund accepts purchase and redemption orders.

Secondary market trading in Fund shares may be halted by a stock exchange because of market conditions or other reasons. In addition, trading in Fund shares on a stock exchange or in any market may be subject to trading halts caused by extraordinary market volatility pursuant to “circuit breaker” rules on the stock exchange or market. There can be no assurance that the requirements necessary to maintain the listing or trading of Fund shares will continue to be met or will remain unchanged.

Shares of the Fund May Trade at Prices Other Than NAV. Shares of the Fund trade on stock exchanges at prices at, above or below their most recent NAV. The NAV of the Fund is calculated at the end of each business day and fluctuates with changes in the market value of the Fund’s holdings since the most recent calculation. The trading prices of the Fund’s shares fluctuate continuously throughout trading hours based on market supply and demand rather than NAV. The trading prices of the Fund’s shares may deviate significantly from NAV during periods of market volatility. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV. However, because shares can be created and redeemed in Creation Units at NAV (unlike shares of many closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their NAVs), BFA believes that large discounts or premiums to the NAV of the Fund are not likely to be sustained over the long-term. While the creation/redemption feature is designed to make it likely that the Fund’s shares normally will trade on stock exchanges at prices close to the Fund’s next calculated NAV, exchange prices are not expected to correlate exactly with the Fund’s NAV due to timing reasons as well as market supply and demand factors. In addition, disruptions to creations and

redemptions or extreme market volatility may result in trading prices for shares of the Fund that differ significantly from its NAV.

Costs of Buying or Selling Fund Shares. Buying or selling Fund shares on an exchange involves two types of costs that apply to all securities transactions. When buying or selling shares of the Fund through a broker, you will likely incur a brokerage commission or other charges imposed by brokers as determined by that broker. In addition, you may incur the cost of the “spread” – that is, the difference between what investors are willing to pay for Fund shares (the “bid” price) and the price at which they are willing to sell Fund shares (the “ask” price). Because of the costs inherent in buying or selling Fund shares, frequent trading may detract significantly from investment results and an investment in Fund shares may not be advisable for investors who anticipate regularly making small investments.

Mid-Capitalization Companies Risk. Many of the companies in which the Fund invests are considered mid-capitalization companies. Stock prices of mid-capitalization companies may be more volatile than those of large-capitalization companies and, therefore, the Fund’s share price may be more volatile than those of funds that invest a larger percentage of their assets in stocks issued by large-capitalization companies. Stock prices of mid-capitalization companies are also more vulnerable than those of large-capitalization companies to adverse business or economic developments, and the stocks of mid-capitalization companies may be less liquid, making it difficult for the Fund to buy and sell them. In addition, mid-capitalization companies generally have less diverse product lines than large-capitalization companies and are more susceptible to adverse developments related to their products.

Non-Diversification Risk. The Fund is classified as “non-diversified.” This means that the Fund may invest a large percentage of its assets in securities issued by or representing a small number of issuers. As a result, the Fund may be more susceptible to the risks associated with these particular issuers, or to a single economic, political or regulatory occurrence affecting these issuers.

Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers are subject to all of the risks of investing in the markets where such issuers are located, including heightened risks of inflation or nationalization and market fluctuations caused by economic and political developments. As a result of investing in non-U.S. securities, the Fund may be subject to increased risk of loss caused by any of the factors listed below:

  • Lower levels of liquidity and market efficiency;
  • Greater securities price volatility;
  • Exchange rate fluctuations and exchange controls;
  • Less availability of public information about issuers;
  • Limitations on foreign ownership of securities;
  • Imposition of withholding or other taxes;
  • Imposition of restrictions on the expatriation of the funds or other assets of the Fund;
  • Higher transaction and custody costs and delays in settlement procedures;
  • Difficulties in enforcing contractual obligations;
  • Lower levels of regulation of the securities market;
  • Weaker accounting, disclosure and reporting requirements; and
  • Legal principles related to corporate governance, directors’ fiduciary duties and liabilities and stockholders’ rights in markets in which the Fund invests may differ and/or may not be as extensive or protective as those that apply in the United States.

Passive Investment Risk. The Fund is not actively managed and may be affected by a general decline in market segments related to the Underlying Index. The Fund invests in securities included in, or representative of, the Underlying Index regardless of their investment merits. BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

Privatization Risk. Some countries in which the Fund invests have begun a process of privatizing certain entities and industries. In some instances, investors in newly privatized entities have suffered losses due to the inability of the newly privatized entities to adjust quickly to a competitive environment or changing regulatory and legal standards or, in some cases, due to re-nationalization of such privatized entities. There is no assurance that such losses will not recur.

Reliance on Trading Partners Risk. The economies of the ACWI ex US consumer discretionary sector countries are dependent on each other and on the United States as key trading partners. Reduction in spending on the products and services of the ACWI ex US consumer discretionary sector countries by any of their key trading partners, institution of tariffs or other trade barriers or a slowdown in the economies of any of their key trading partners may cause an adverse impact on the economies of the ACWI ex US consumer discretionary sector countries.

U.S. Trading Partners Risk. The United States is a significant, and in some cases the most significant, trading partner of or foreign investor in certain ACWI ex US consumer discretionary sector countries and the economies of these countries may be particularly affected by changes in the U.S. economy. Decreasing U.S. imports, new trade regulations, changes in the U.S. dollar exchange rate or a recession in the United States may have a material adverse effect on the economies of ACWI ex US consumer discretionary sector countries.

Retail Sector Risk. The retail sector may be affected by changes in domestic and international economies, consumer confidence, disposable household income and spending, and consumer tastes and preferences. Companies in the retail sector face intense competition, which may have an adverse effect on their profitability. The success of companies in the retail sector may be strongly affected by social trends and marketing campaigns. Companies in the retail sector may be dependent on outside financing, which may be difficult to obtain. Many of these companies are dependent on third party suppliers and distribution systems. Retail companies may be unable to protect their intellectual property rights or may be liable for infringing the intellectual property rights of others.

Risk of Investing in Japan. Japan may be subject to political, economic, nuclear, and labor risks. Any of these risks, individually or in the aggregate, can impact an investment made in Japan.

  • Political Risk. Historically, Japan has had unpredictable national politics and may experience frequent political turnover. Future political developments may lead to changes in policy that might adversely affect the Fund’s investments.
  • Large Government Debt Risk. The Japanese economy faces several concerns, including a financial system with large levels of nonperforming loans, over-leveraged corporate balance sheets, extensive cross-ownership by major corporations, a changing corporate governance structure, and large government deficits. These issues may cause a slowdown of the Japanese economy.
  • Currency Risk. The Japanese yen has fluctuated widely at times and any increase in its value may cause a decline in exports that could weaken the economy.
  • Nuclear Risk. The nuclear power plant catastrophe in Japan in March of 2011 may have short-term and long-term effects on the nuclear energy industry, the extent of which are currently unknown.
  • Labor Risk. Japan has an aging workforce. It is a labor market that is undergoing fundamental structural changes, as traditional lifetime employment clashes with the need for increased labor mobility, which may adversely affect Japan’s economic competitiveness.
  • Geographic Risk. Natural disasters, such as earthquakes, could occur in Japan or surrounding areas and could negatively affect the Japanese economy, and, in turn, could negatively affect the Fund.

Securities Lending Risk. The Fund may engage in securities lending. Securities lending involves the risk that the Fund may lose money because the borrower of the Fund’s loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for the loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Security Risk. Some geographic areas in which the Fund invests have experienced acts of terrorism or strained international relations due to territorial disputes, historical animosities or other defense concerns. These situations may cause uncertainty in the markets of these geographic areas and may adversely affect the performance of their economies.

Structural Risk. Certain political, economic, legal and currency risks have contributed to a high degree of price volatility in the equity markets of the ACWI ex US consumer discretionary sector countries and could adversely affect investments in the Fund:

Political and Social Risk. Disparities of wealth, the pace and success of democratization and ethnic, religious and racial disaffection, among other factors, have led to social unrest, violence and labor unrest in some ACWI ex US consumer discretionary sector countries. Unanticipated or sudden political or social developments may result in sudden and significant investment losses.

Economic Risk. Some ACWI ex US consumer discretionary sector countries may experience economic instability, including instability resulting from substantial rates of inflation or significant devaluations of their currency, or economic recessions causing a negative effect on the economies and securities markets of their economies. Some of these countries may also impose restrictions on the exchange or export of currency or adverse currency exchange rates and may be characterized by a lack of available currency hedging instruments.

Expropriation and/or Nationalization Risk. Investments in certain ACWI ex US consumer discretionary sector countries may be subject to loss due to expropriation or nationalization of assets and property or the imposition of restrictions on foreign investments and repatriation of capital.

Large Government Debt Risk. Chronic structural public sector deficits in some ACWI ex US consumer discretionary sector countries may adversely impact investments in the Fund.

Tracking Error Risk. Imperfect correlation between the Fund’s portfolio securities and those in the Underlying Index, rounding of prices, changes to the Underlying Index and regulatory requirements may cause tracking error, which is the divergence of the Fund’s performance from that of the Underlying Index. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Underlying Index does not. Because the Fund employs a representative sampling strategy, the Fund may experience tracking error to a greater extent than a fund that seeks to replicate an index.

Valuation Risk. Because non-U.S. exchanges may be open on days when the Fund does not price its shares, the value of the securities in the Fund’s portfolio may change on days when shareholders will not be able to purchase or sell the Fund’s shares. In addition, for purposes of calculating the Fund’s NAV, the value of assets denominated in non-U.S. currencies is converted into U.S. dollars using exchange rates deemed appropriate by BFA. This conversion may result in a difference between the prices used to calculate the Fund’s NAV and the prices used by the Underlying Index, which, in turn, could result in a difference between the Fund’s performance and the performance of the Underlying Index.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

Media Sector Risk. Companies in the media sector may encounter distressed cash flows due to the need to commit substantial capital to meet increasing competition, particularly in formulating new products and services using new technology. Media companies are subject to risks that include cyclicality of revenues and earnings, a potential decrease in the discretionary income of targeted individuals, changing consumer tastes and interests, competition in the industry and the potential for increased state and federal regulation. Advertising spending is an important source of

revenue for media companies. During economic downturns advertising spending typically decreases and as a result, media companies tend to generate less revenue.

Portfolio Holdings Information

A description of the Trust’s policies and procedures with respect to the disclosure of the Fund’s portfolio securities is available in the Fund’s Statement of Additional Information (“SAI”). The top holdings of the Fund can be found at www.iShares.com. Fund fact sheets provide information regarding the Fund’s top holdings and may be requested by calling 1-800-iShares (1-800-474-2737).

Management

Investment Adviser. As investment adviser, BFA has overall responsibility for the general management and administration of the Trust. BFA provides an investment program for the Fund and manages the investment of the Fund’s assets. In managing the Fund, BFA may draw upon the research and expertise of its asset management affiliates with respect to certain portfolio securities. In seeking to achieve the Fund’s investment objective, BFA uses teams of portfolio managers, investment strategists and other investment specialists. This team approach brings together many disciplines and leverages BFA’s extensive resources.

Pursuant to the Investment Advisory Agreement between BFA and the Trust (entered into on behalf of the Fund), BFA is responsible for substantially all expenses of the Fund, except interest expenses, taxes, brokerage expenses, future distribution fees or expenses and extraordinary expenses.

For its investment advisory services to the Fund, BFA is entitled to receive a management fee from the Fund based on a percentage of the Fund’s average daily net assets, at the annual rate of 0.48%.

BFA is located at 400 Howard Street, San Francisco, CA 94105. It is a wholly owned subsidiary of BTC, which in turn is indirectly wholly-owned by BlackRock, Inc. (“BlackRock”). As of September 30, 2011, BTC and its affiliates, including BFA and BlackRock, provided investment advisory services for assets in excess of $3.35 trillion. BFA, BTC, BlackRock Execution Services, BlackRock and their affiliates deal, trade and invest for their own accounts in the types of securities in which the Fund may also invest.

A discussion regarding the basis for the Trust’s Board of Trustees’ (the “Board”) approval of the Investment Advisory Agreement with BFA is available in the Fund’s annual report for the period ended July 31.

Portfolio Managers. Rene Casis, Diane Hsiung and Greg Savage are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager is responsible for various functions related to portfolio management, including, but not limited to, investing cash inflows, coordinating with members of his or her portfolio management team to focus on certain asset classes, implementing investment strategy, researching and reviewing investment strategy and overseeing members of his or her portfolio management team that have more limited responsibilities.

Rene Casis has been employed by BFA (formerly, Barclays Global Fund Advisors (“BGFA”)) and BTC (formerly, Barclays Global Investors, N.A. (“BGI”)) as a senior portfolio manager since 2009. From 2005 to 2009, Mr. Casis was a trader at Barclays Capital. Prior to that, Mr. Casis was a portfolio manager from 2000 to 2005 for BGFA and BGI. Mr. Casis has been a Portfolio Manager of the Fund since 2010.

Diane Hsiung has been employed by BFA and BTC as a senior portfolio manager since 2007. Prior to that, Ms. Hsiung was a portfolio manager from 2002 to 2006 for BGFA and BGI. Ms. Hsiung has been a Portfolio Manager of the Fund since inception.

Greg Savage has been employed by BFA and BTC as a senior portfolio manager since 2006. Prior to that, Mr. Savage was a portfolio manager from 2001 to 2006 for BGFA and BGI. Mr. Savage has been a Portfolio Manager of the Fund since inception.

The Fund’s SAI provides additional information about the Portfolio Managers’ compensation, other accounts managed by the Portfolio Managers and the Portfolio Managers’ ownership (if any) of shares in the Fund.

Administrator, Custodian and Transfer Agent. State Street Bank and Trust Company (“State Street”) is the administrator, custodian and transfer agent for the Fund.

Conflicts of Interest. BFA wants you to know that there are certain entities with which BFA has relationships that may give rise to conflicts of interest, or the appearance of conflicts of interest. These entities include the following: BFA’s affiliates (including BlackRock and The PNC Financial Services Group, Inc., and each of their affiliates, directors, partners, trustees, managing members, officers and employees (collectively, the “Affiliates”)) and BlackRock’s significant shareholder, Barclays Bank PLC and its affiliates, including Barclays PLC (each, an “Entity” and together, the “Entities”).

The activities of BFA, the Affiliates and the Entities in the management of, or their interest in, their own accounts and other accounts they manage, may present conflicts of interest that could disadvantage the Fund and the shareholders. BFA and its Affiliates or the Entities provide investment management services to other funds and discretionary managed accounts that may follow an investment program similar to that of the Fund. BFA, its Affiliates and the Entities are involved worldwide with a broad spectrum of financial services and asset management activities and may engage in the ordinary course of business in activities in which their interests or the interests of their clients may conflict with those of the Fund. BFA, one or more of the Affiliates or the Entities acts, or may act, as an investor, investment banker, research provider, investment manager, financier, underwriter, advisor, market maker, trader, prime broker, lender, agent or principal, and have other direct and indirect interests, in securities, currencies and other instruments in which the Fund may directly or indirectly invest. Thus, it is likely that the Fund will have multiple business relationships with and will invest in, engage in transactions with, make voting decisions with respect to, or obtain services from, entities for which BFA, an Affiliate or an Entity performs or seeks to perform investment banking or other services.

BFA or one or more Affiliates or Entities may engage in proprietary trading and advise accounts and funds that have investment objectives similar to those of the Fund and/

or that engage in and compete for transactions in the same types of securities, currencies and other instruments as the Fund, including in securities issued by other open-end and closed-end investment management companies, including investment companies that are affiliated with the Fund and BFA, to the extent permitted under the Investment Company Act of 1940, as amended (the “1940 Act”). The trading activities of BFA, these Affiliates and Entities are carried out without reference to positions held directly or indirectly by the Fund and may result in BFA, an Affiliate or an Entity having positions that are adverse to those of the Fund.

No Affiliate or Entity is under any obligation to share any investment opportunity, idea or strategy with the Fund. As a result, an Affiliate or an Entity may compete with the Fund for appropriate investment opportunities. As a result of this and several other factors, the results of the Fund’s investment activities may differ from those of an Affiliate or an Entity and of other accounts managed by an Affiliate or an Entity, and it is possible that the Fund could sustain losses during periods in which one or more Affiliates or Entities and other accounts achieve profits on their trading for proprietary or other accounts. The opposite result is also possible.

The Fund may, from time to time, enter into transactions in which BFA or an Affiliate’s or an Entity’s clients have an interest adverse to the Fund. Furthermore, transactions undertaken by Affiliate-advised clients may adversely impact the Fund. Transactions by one or more Affiliate- or Entity-advised clients or BFA may have the effect of diluting or otherwise disadvantaging the values, prices or investment strategies of the Fund.

An Entity may maintain securities indices as part of the product offerings. Index-based funds seek to track the performance of securities indices and may use the name of the index in the fund name. Index providers, including the Entities, may be paid licensing fees for use of their indices or index names. Entities will not be obligated to license their indices to BFA and its Affiliates, and BFA and its Affiliates will not be assured that the terms of any index licensing agreement with the Entities will be as favorable as those terms offered to other index licensees.

The Fund’s activities may be limited because of regulatory restrictions applicable to one or more Affiliates or Entities, and/or their internal policies designed to comply with such restrictions. In addition, the Fund may invest in securities of companies with which an Affiliate or an Entity has or is trying to develop investment banking relationships or in which an Affiliate or an Entity has significant debt or equity investments. The Fund also may invest in securities of companies for which an Affiliate or an Entity provides or may some day provide research coverage. An Affiliate or an Entity may have business relationships with and purchase or distribute or sell services or products from or to distributors, consultants or others who recommend the Fund or who engage in transactions with or for the Fund, and may receive compensation for such services. The Fund may also make brokerage and other payments to Affiliates or Entities in connection with the Fund’s portfolio investment transactions.

Pursuant to a securities lending program approved by the Board, the Fund has retained an Affiliate of BFA to serve as the securities lending agent for the Fund to the extent that the Fund participates in the securities lending program. For these services, the lending agent may receive a fee from the Fund, including a fee based on the returns earned on the Fund’s investment of the cash received as collateral for any loaned

securities. In addition, one or more Affiliates may be among the entities to which the Fund may lend its portfolio securities under the securities lending program.

The activities of BFA, the Affiliates or Entities may give rise to other conflicts of interest that could disadvantage the Fund and the shareholders. BFA has adopted policies and procedures designed to address these potential conflicts of interest. See the Fund’s SAI for further information.

Shareholder Information

Additional shareholder information, including how to buy and sell shares of the Fund, is available free of charge by calling toll-free: 1-800-iShares (1-800-474-2737) or visiting our website at www.iShares.com.

Buying and Selling Shares. Shares of the Fund may be acquired or redeemed directly from the Fund only in Creation Units or multiples thereof, as discussed in the Creations and Redemptions section of this Prospectus. Only an Authorized Participant (as defined in the Creations and Redemptions section) may engage in creation or redemption transactions directly with the Fund. Once created, shares of the Fund generally trade in the secondary market in amounts less than a Creation Unit.

Shares of the Fund are listed on a national securities exchange for trading during the trading day. Shares can be bought and sold throughout the trading day like shares of other publicly-traded companies. The Trust does not impose any minimum investment for shares of the Fund purchased on an exchange. The Fund’s shares trade under the trading symbol “AXDI.”

Buying or selling Fund shares on an exchange involves two types of costs that may apply to all securities transactions. When buying or selling shares of the Fund through a broker, you will likely incur a brokerage commission or other charges determined by your broker. The commission is frequently a fixed amount and may be a significant proportional cost for investors seeking to buy or sell small amounts of shares. In addition, you may incur the cost of the “spread” – that is, any difference between the bid price and the ask price. The spread varies over time for shares of the Fund based on the trading volume and market liquidity, and is generally lower if the Fund has a lot of trading volume and market liquidity, and higher if the Fund has little trading volume and market liquidity.

The Board has adopted a policy of not monitoring for frequent purchases and redemptions of Fund shares (“frequent trading”) that appear to attempt to take advantage of a potential arbitrage opportunity presented by a lag between a change in the value of the Fund’s portfolio securities after the close of the primary markets for the Fund’s portfolio securities and the reflection of that change in the Fund’s NAV (“market timing”), because the Fund generally sells and redeems its shares directly through transactions that are in-kind and/or for cash, subject to the conditions described below under Creations and Redemptions. The Board has not adopted a policy of monitoring for other frequent trading activity because shares of the Fund are listed for trading on a national securities exchange.

The national securities exchange on which the Fund’s shares are listed is open for trading Monday through Friday and is closed on weekends and the following holidays:

New Year’s Day, Martin Luther King, Jr. Day, Presidents’ Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day. The Fund’s primary listing exchange is NYSE Arca.

Section 12(d)(1) of the 1940 Act restricts investments by investment companies in the securities of other investment companies. Registered investment companies are permitted to invest in the Fund beyond the limits set forth in Section 12(d)(1), subject to certain terms and conditions set forth in SEC rules or in an SEC exemptive order issued to the Trust. In order for a registered investment company to invest in shares of the Fund beyond the limitations of Section 12(d)(1) pursuant to the exemptive relief obtained by the Trust, the registered investment company must enter into an agreement with the Trust.

Book Entry. Shares of the Fund are held in book-entry form, which means that no stock certificates are issued. The Depository Trust Company (“DTC”) or its nominee is the record owner of all outstanding shares of the Fund and is recognized as the owner of all shares for all purposes.

Investors owning shares of the Fund are beneficial owners as shown on the records of DTC or its participants. DTC serves as the securities depository for shares of the Fund. DTC participants include securities brokers and dealers, banks, trust companies, clearing corporations and other institutions that directly or indirectly maintain a custodial relationship with DTC. As a beneficial owner of shares, you are not entitled to receive physical delivery of stock certificates or to have shares registered in your name, and you are not considered a registered owner of shares. Therefore, to exercise any right as an owner of shares, you must rely upon the procedures of DTC and its participants. These procedures are the same as those that apply to any other securities that you hold in book-entry or “street name” form.

Share Prices. The trading prices of the Fund’s shares in the secondary market generally differ from the Fund’s daily NAV and are affected by market forces such as supply and demand, economic conditions and other factors. Information regarding the intraday value of shares of the Fund, also known as the “indicative optimized portfolio value” (“IOPV”), is disseminated every 15 seconds throughout the trading day by the national securities exchange on which the Fund’s shares are listed or by market data vendors or other information providers. The IOPV is based on the current market value of the securities and/or cash required to be deposited in exchange for a Creation Unit. The IOPV does not necessarily reflect the precise composition of the current portfolio of securities held by the Fund at a particular point in time or the best possible valuation of the current portfolio. Therefore, the IOPV should not be viewed as a “real-time” update of the Fund’s NAV, which is computed only once a day. The IOPV is generally determined by using both current market quotations and/or price quotations obtained from broker-dealers that may trade in the portfolio securities held by the Fund. The quotations of certain Fund holdings may not be updated during U.S. trading hours if such holdings do not trade in the United States. The Fund is not involved in, or responsible for, the calculation or dissemination of the IOPV and makes no representation or warranty as to its accuracy.

Determination of Net Asset Value. The NAV of the Fund normally is determined once daily Monday through Friday, generally as of the regularly scheduled close of

business of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m., Eastern time) on each day that the NYSE is open for trading, based on prices at the time of closing provided that (a) any Fund assets or liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers (as detailed below) and (b) U.S. fixed income assets may be valued as of the announced closing time for trading in fixed income instruments in a particular market or exchange. The NAV of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets held by the Fund, and its liabilities, are determined pursuant to valuation policies and procedures approved by the Board. The Fund’s assets and liabilities are valued primarily on the basis of market quotations.

Equity investments are valued at market value, which is generally determined using the last reported official closing price or last trading price on the exchange or market on which the security is primarily traded at the time of valuation.

The Fund invests in foreign securities. Foreign currency exchange rates are generally determined as of 4:00 p.m., London time. Foreign securities owned by the Fund may trade on weekends or other days when the Fund does not price its shares. As a result, the Fund’s NAV may change on days when Authorized Participants will not be able to purchase or redeem Fund shares.

Generally, trading in foreign securities, U.S. government securities, money market instruments and certain fixed-income securities is substantially completed each day at various times prior to the close of business on the NYSE. The values of such securities used in computing the NAV of the Fund are determined as of such times.

When market quotations are not readily available or are believed by BFA to be unreliable, the Fund’s investments are valued at fair value. Fair value determinations are made by BFA in accordance with policies and procedures approved by the Fund’s Board. BFA may conclude that a market quotation is not readily available or is unreliable if a security or other asset or liability does not have a price source due to its lack of liquidity, if a market quotation differs significantly from recent price quotations or otherwise no longer appears to reflect fair value, where the security or other asset or liability is thinly traded, or where there is a significant event subsequent to the most recent market quotation. A “significant event” is an event that, in the judgment of BFA, is likely to cause a material change to the closing market price of the asset or liability held by the Fund. Foreign securities whose values are affected by volatility that occurs in U.S. markets on a trading day after the close of foreign securities markets may be fair valued.

Fair value represents a good faith approximation of the value of an asset or liability. The fair value of an asset or liability held by the Fund is the amount the Fund might reasonably expect to receive from the current sale of that asset or the cost to extinguish that liability in an arm’s-length transaction. Valuing the Fund’s investments using fair value pricing will result in prices that may differ from current market valuations and that may not be the price at which those investments could have been

sold during the period in which the particular fair values were used. Use of fair value prices and certain current market valuations could result in a difference between the prices used to calculate the Fund’s NAV and the prices used by the Underlying Index, which, in turn, could result in a difference between the Fund’s performance and the performance of the Underlying Index.

The value of assets or liabilities denominated in non-U.S. currencies will be converted into U.S. dollars using exchange rates deemed appropriate by BFA as investment adviser. Use of a rate different from the rate used by the Index Provider may adversely affect the Fund’s ability to track the Underlying Index.

Dividends and Distributions

General Policies. Dividends from net investment income, if any, generally are declared and paid semi-annually by the Fund. Distributions of net realized securities gains, if any, generally are declared and paid once a year, but the Trust may make distributions on a more frequent basis for the Fund. The Trust reserves the right to declare special distributions if, in its reasonable discretion, such action is necessary or advisable to preserve its status as a regulated investment company (“RIC”) or to avoid imposition of income or excise taxes on undistributed income or realized gains.

Dividends and other distributions on shares of the Fund are distributed on a pro rata basis to beneficial owners of such shares. Dividend payments are made through DTC participants and indirect participants to beneficial owners then of record with proceeds received from the Fund.

Dividend Reinvestment Service. No dividend reinvestment service is provided by the Trust. Broker-dealers may make available the DTC book-entry Dividend Reinvestment Service for use by beneficial owners of the Fund for reinvestment of their dividend distributions. Beneficial owners should contact their broker to determine the availability and costs of the service and the details of participation therein. Brokers may require beneficial owners to adhere to specific procedures and timetables. If this service is available and used, dividend distributions of both income and realized gains will be automatically reinvested in additional whole shares of the Fund purchased in the secondary market.

Taxes. As with any investment, you should consider how your investment in shares of the Fund will be taxed. The tax information in this Prospectus is provided as general information, based on current law. You should consult your own tax professional about the tax consequences of an investment in shares of the Fund.

Unless your investment in Fund shares is made through a tax-exempt entity or tax-deferred retirement account, such as an IRA, you need to be aware of the possible tax consequences when the Fund makes distributions or you sell Fund shares.

Taxes on Distributions. Distributions from the Fund’s net investment income (other than qualified dividend income), including distributions of income from securities lending and distributions out of the Fund’s net short-term capital gains, if any, are taxable to you as ordinary income. Distributions by the Fund of net long-term capital gains in excess of net short-term capital losses (capital gain dividends) are taxable to you as long-term capital gains, generally at a 15% tax rate (0% at certain income levels), regardless of how long you have held the Fund’s shares. Distributions by the

Fund that qualify as qualified dividend income are taxable to you at long-term capital gain rates for taxable years beginning on or before December 31, 2012. The 15% and 0% tax rates expire for taxable years beginning after December 31, 2012. Maximum long-term capital gain income tax rates are scheduled to rise to 20% in 2013. Beginning in 2013, a 3.8% U.S. federal Medicare contribution tax will be imposed on “net investment income,” including interest, dividends, and capital gains, of U.S. individuals with income exceeding $200,000 (or $250,000 if married and filing jointly), and of estates and trusts.

Dividends will be qualified dividend income to you if they are attributable to qualified dividend income received by the Fund. Generally, qualified dividend income includes dividend income from taxable U.S. corporations and qualified non-U.S. corporations, provided that the Fund satisfies certain holding period requirements in respect of the stock of such corporations and has not hedged its position in the stock in certain ways. Substitute dividends received by the Fund with respect to dividends paid on securities lent out will not be qualified dividend income. For this purpose, a qualified non-U.S. corporation means any non-U.S. corporation that is eligible for benefits under a comprehensive income tax treaty with the United States, which includes an exchange of information program or if the stock with respect to which the dividend was paid is readily tradable on an established United States securities market. The term excludes a corporation that is a passive foreign investment company.

Dividends received by the Fund from a real estate investment trust (“REIT”) or another RIC generally are qualified dividend income only to the extent the dividend distributions are made out of qualified dividend income received by such REIT or RIC. It is expected that dividends received by the Fund from a REIT and distributed to a shareholder generally will be taxable to the shareholder as ordinary income.

For a dividend to be treated as qualified dividend income, the dividend must be received with respect to a share of stock held without being hedged by the Fund, and with respect to a share of the Fund held without being hedged by you, for 61 days during the 121-day period beginning at the date which is 60 days before the date on which such share becomes ex-dividend with respect to such dividend or, in the case of certain preferred stock, 91 days during the 181-day period beginning 90 days before such date.

If your Fund shares are loaned out pursuant to a securities lending arrangement, you may lose the ability to use foreign tax credits passed through by the Fund or to treat Fund dividends paid while the shares are held by the borrower as qualified dividend income.

In general, your distributions are subject to U.S. federal income tax for the year when they are paid. Certain distributions paid in January, however, may be treated as paid on December 31 of the prior year.

If the Fund’s distributions exceed current and accumulated earnings and profits, all or a portion of the distributions made in the taxable year may be recharacterized as a return of capital to shareholders. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and result in a higher capital gain or lower capital loss when those shares on which the distribution was received are

sold. Once a shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain, if the shareholder holds shares of the Fund as capital assets.

If you are neither a resident nor a citizen of the United States or if you are a non-U.S. entity, the Fund’s ordinary income dividends (which include distributions of net short-term capital gains) will generally be subject to a 30% U.S. withholding tax, unless a lower treaty rate applies, provided that withholding tax will generally not apply to any gain or income realized by a non-U.S. shareholder in respect of any distributions of long-term capital gains or upon the sale or other disposition of shares of the Fund.

A 30% withholding tax will be imposed on dividends paid after December 31, 2013, and redemption proceeds paid after December 31, 2014, to (i) foreign financial institutions including non-U.S. investment funds unless they agree to collect and disclose to the Internal Revenue Service (“IRS”) information regarding their direct and indirect U.S. account holders and (ii) certain other foreign entities, unless they certify certain information regarding their direct and indirect U.S. owners. To avoid withholding, foreign financial institutions will need to enter into agreements with the IRS that state that they will provide the IRS information, including the name, address and taxpayer identification number of direct and indirect U.S. account holders, comply with due diligence procedures with respect to the identification of U.S. accounts, report to the IRS certain information with respect to U.S. accounts maintained, agree to withhold tax on certain payments made to non-compliant foreign financial institutions or to account holders who fail to provide the required information, and determine certain other information as to their account holders. Other foreign entities will need to provide the name, address, and taxpayer identification number of each substantial U.S. owner or certifications of no substantial U.S. ownership unless certain exceptions apply.

Dividends, interest and capital gains earned by the Fund with respect to non-U.S. securities may give rise to withholding and other taxes imposed by non-U.S. countries. Tax conventions between certain countries and the United States may reduce or eliminate such taxes. If more than 50% of the total assets of the Fund at the close of a year consists of non-U.S. stocks or securities, the Fund may “pass through” to you certain non-U.S. income taxes (including withholding taxes) paid by the Fund. This means that you would be considered to have received as an additional dividend your share of such non-U.S. taxes, but you may be entitled to either a corresponding tax deduction in calculating your taxable income, or, subject to certain limitations, a credit in calculating your U.S. federal income tax.

For purposes of foreign tax credits for U.S. shareholders of the Fund, foreign capital gains taxes may not produce associated foreign source income, thereby limiting a U.S. person’s ability to use such credits.

If you are a resident or a citizen of the United States, by law, back-up withholding will apply to your distributions and proceeds if you have not provided a taxpayer identification number or social security number and made other required certifications.

Taxes When Shares are Sold. Currently, any capital gain or loss realized upon a sale of Fund shares is generally treated as a long-term gain or loss if the shares have been held for more than one year. Any capital gain or loss realized upon a sale of Fund

shares held for one year or less is generally treated as short-term gain or loss, except that any capital loss on the sale of shares held for six months or less is treated as long-term capital loss to the extent that capital gain dividends were paid with respect to such shares. Beginning in 2013, any such capital gains, including from sales of Fund shares or from capital gain dividends, will be included in “net investment income” for purposes of the 3.8% U.S. federal Medicare contribution tax mentioned above.

The foregoing discussion summarizes some of the consequences under current U.S. federal tax law of an investment in the Fund. It is not a substitute for personal tax advice. You may also be subject to state and local taxation on Fund distributions and sales of shares. Consult your personal tax adviser about the potential tax consequences of an investment in shares of the Fund under all applicable tax laws.

Creations and Redemptions. Prior to trading in the secondary market, shares of the Fund are “created” at NAV by market makers, large investors and institutions only in block-size Creation Units of 50,000 shares or multiples thereof. Each “creator” or “Authorized Participant” enters into an authorized participant agreement with the Fund’s distributor, SEI Investments Distribution Co. (the “Distributor”). Only an Authorized Participant may create or redeem Creation Units directly with the Fund. A creation transaction, which is subject to acceptance by the transfer agent, generally takes place when an Authorized Participant deposits into the Fund a designated portfolio of securities and a specified amount of cash approximating the holdings of the Fund in exchange for a specified number of Creation Units. To the extent practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund.

Similarly, shares can be redeemed only in Creation Units, generally for a designated portfolio of securities and a specified amount of cash held by the Fund (“Fund Securities”). Except when aggregated in Creation Units, shares are not redeemable by the Fund. The prices at which creations and redemptions occur are based on the next calculation of NAV after an order is received in a form described in the authorized participant agreement.

The Fund intends to comply with the U.S. federal securities laws in accepting securities for deposit and satisfying redemptions with redemption securities by, among other means, assuring that any securities accepted for deposit and any securities used to satisfy redemption requests will be sold in transactions that would be exempt from registration under the Securities Act of 1933, as amended (the “1933 Act”). Further, an Authorized Participant that is not a “qualified institutional buyer,” as such term is defined under Rule 144A of the 1933 Act, will not be able to receive Fund Securities that are restricted securities eligible for resale under Rule 144A.

Creations and redemptions must be made through a firm that is either a member of the Continuous Net Settlement System of the National Securities Clearing Corporation or a DTC participant and has executed an agreement with the Distributor with respect to creations and redemptions of Creation Unit aggregations. Information about the procedures regarding creation and redemption of Creation Units (including the cut-off times for receipt of creation and redemption orders) is included in the Fund’s SAI.

Because new shares may be created and issued on an ongoing basis, at any point during the life of the Fund a “distribution,” as such term is used in the 1933 Act, may be occurring. Broker-dealers and other persons are cautioned that some activities on their part may, depending on the circumstances, result in their being deemed participants in a distribution in a manner that could render them statutory underwriters and subject to the prospectus delivery and liability provisions of the 1933 Act. Any determination of whether one is an underwriter must take into account all the relevant facts and circumstances of each particular case.

Broker-dealers should also note that dealers who are not “underwriters” but are participating in a distribution (as contrasted to ordinary secondary transactions), and thus dealing with shares that are part of an “unsold allotment” within the meaning of Section 4(3)(C) of the 1933 Act, would be unable to take advantage of the prospectus delivery exemption provided by Section 4(3) of the 1933 Act. For delivery of prospectuses to exchange members, the prospectus delivery mechanism of Rule 153 under the 1933 Act is available only with respect to transactions on a national securities exchange.

Costs Associated with Creations and Redemptions. Authorized Participants are charged standard creation and redemption transaction fees to offset transfer and other transaction costs associated with the issuance and redemption of Creation Units. The standard creation and redemption transaction fees are set forth in the table below. The standard creation transaction fee is charged to the Authorized Participant on the day such Authorized Participant creates a Creation Unit, and is the same regardless of the number of Creation Units purchased by the Authorized Participant on the applicable business day. Similarly, the standard redemption transaction fee is charged to the Authorized Participant on the day such Authorized Participant redeems a Creation Unit, and is the same regardless of the number of Creation Units redeemed by the Authorized Participant on the applicable business day. Creations and redemptions for cash (when cash creations and redemptions (in whole or in part) are available or specified) are also subject to an additional charge (up to the maximum amounts shown in the table below). This charge is intended to compensate for brokerage, tax, foreign exchange, execution, market impact and other costs and expenses related to cash transactions. Investors who use the services of a broker or other financial intermediary may pay fees for such services.

The following table shows, as of September 30, 2011, the approximate value of one Creation Unit, standard fees and maximum additional charges for creations and redemptions (as described above):

* As a percentage of the net asset value per Creation Unit, inclusive, in the case of redemptions, of the standard redemption transaction fee.

Householding. Householding is an option available to certain Fund investors. Householding is a method of delivery, based on the preference of the individual investor, in which a single copy of certain shareholder documents can be delivered to investors who share the same address, even if their accounts are registered under different names. Please contact your broker-dealer if you are interested in enrolling in householding and receiving a single copy of prospectuses and other shareholder documents, or if you are currently enrolled in householding and wish to change your householding status.

Distribution

The Distributor distributes Creation Units for the Fund on an agency basis. The Distributor does not maintain a secondary market in shares of the Fund. The Distributor has no role in determining the policies of the Fund or the securities that are purchased or sold by the Fund. The Distributor’s principal address is One Freedom Valley Drive, Oaks, PA 19456.

In addition, BFA or its Affiliates make payments to broker-dealers, banks or other financial intermediaries (together, “intermediaries”) related to marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems, or their making shares of the Fund and certain other iShares funds available to their customers. Such payments, which may be significant to the intermediary, are not made by the Fund. Rather, such payments are made by BFA or its Affiliates from their own resources, which come directly or indirectly in part from fees paid by the iShares funds complex. Payments of this type are sometimes referred to as revenue-sharing payments. A financial intermediary may make decisions about which investment options it recommends or makes available, or the level of services provided, to its customers based on the revenue-sharing payments it is eligible to receive. Therefore, such payments to an intermediary create conflicts of interest between the intermediary and its customers and may cause the intermediary to recommend the Fund or other iShares funds over another investment. More information regarding these payments is contained in the Fund’s SAI. Please contact your salesperson or other investment professional for more information regarding any such payments his or her firm may receive from BFA or its Affiliates.

Financial Highlights

The financial highlights table is intended to help investors understand the Fund’s financial performance since inception. Certain information reflects financial results for a single share of the Fund. The total returns in the table represent the rate that an investor would have earned (or lost) on an investment in the Fund, assuming reinvestment of all dividends and distributions. This information has been audited by PricewaterhouseCoopers LLP, whose report is included, along with the Fund’s financial statements, in the Fund’s Annual Report (available upon request).

Supplemental Information

I. Premium/Discount Information

The table that follows presents information about the differences between the daily market price on secondary markets for shares of the Fund and the Fund’s NAV. NAV is the price at which the Fund issues and redeems shares. It is calculated in accordance with the standard formula for valuing mutual fund shares. The price used to calculate market returns (“Market Price”) of the Fund generally is determined using the midpoint between the highest bid and the lowest offer on the primary securities exchange on which shares of the Fund are listed for trading, as of the time that the Fund’s NAV is calculated. The Fund’s Market Price may be at, above or below its NAV. The NAV of the Fund will fluctuate with changes in the value of its portfolio holdings. The Market Price of the Fund will fluctuate in accordance with changes in its NAV, as well as market supply and demand.

Premiums or discounts are the differences (expressed as a percentage) between the NAV and Market Price of the Fund on a given day, generally at the time the NAV is calculated. A premium is the amount that the Fund is trading above the reported NAV, expressed as a percentage of the NAV. A discount is the amount that the Fund is trading below the reported NAV, expressed as a percentage of the NAV.

The following information shows the frequency of distributions of premiums and discounts for the Fund from October 1, 2010 through September 30, 2011.

Each line in the table shows the number of trading days in which the Fund traded within the premium/discount range indicated. The number of trading days in each premium/discount range is also shown as a percentage of the total number of trading days in the period covered by the table. All data presented here represents past performance, which cannot be used to predict future results.

Premium/Discount Range

Greater than 2.0% and Less than 2.5% 1 0.40%
Greater than 1.5% and Less than 2.0% 1 0.40

   253 100.00%

II. Total Return Information

The table that follows presents information about the total returns of the Fund and the Underlying Index as of the fiscal year ended July 31, 2011.

“Average Annual Total Returns” represent the average annual change in value of an investment over the periods indicated. “Cumulative Total Returns” represent the total change in value of an investment over the period indicated.

The Fund’s NAV is the value of one share of the Fund as calculated in accordance with the standard formula for valuing mutual fund shares. The NAV return is based on the NAV of the Fund and the market return is based on the Market Price of the Fund. Market Price is determined by using the midpoint between the highest bid and the lowest offer on the primary stock exchange on which shares of the Fund are listed for trading, as of the time that the Fund’s NAV is calculated. Since shares of the Fund did not trade in the secondary market until after the Fund’s inception, for the period from inception to the first day of secondary market trading in shares of the Fund, the NAV of the Fund is used as a proxy for the Market Price to calculate market returns. Market and NAV returns assume that dividends and capital gain distributions have been reinvested in the Fund at Market Price and NAV, respectively.

An index is a statistical composite that tracks a specified financial market or sector. Unlike the Fund, the Underlying Index does not actually hold a portfolio of securities and therefore does not incur the expenses incurred by the Fund. These expenses negatively impact the performance of the Fund. Also, market returns do not include brokerage commissions that may be payable on secondary market transactions. If brokerage commissions were included, market returns would be lower. The returns shown in the following table do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption or sale of Fund shares. The investment return and principal value of shares of the Fund will vary with changes in market conditions. Shares of the Fund may be worth more or less than their original cost when they are redeemed or sold in the market. The Fund’s past performance is no guarantee of future results.

The iShares MSCI ACWI ex US Consumer Staples Sector Index Fund (the “Fund”) seeks investment results that correspond generally to the price and yield performance, before fees and expenses, of the MSCI All Country World ex USA Consumer Staples Index (the “Underlying Index”).

Fees and Expenses

The following table describes the fees and expenses that you will incur if you own shares of the Fund. The investment advisory agreement between iShares Trust (the “Trust”) and BlackRock Fund Advisors (“BFA”) (the “Investment Advisory Agreement”) provides that BFA will pay all operating expenses of the Fund, except interest expenses, taxes, brokerage expenses, future distribution fees or expenses, and extraordinary expenses.

You may also incur usual and customary brokerage commissions when buying or selling shares of the Fund, which are not reflected in the example that follows:

Annual Fund Operating Expenses
(ongoing expenses that you pay each year as a
percentage of the value of your investments)
Management
Fees
Distribution and
Service (12b-1)

Other
Expenses
Total Annual
Fund
Operating
Expenses
0.48% None None 0.48%

Example. This Example is intended to help you compare the cost of owning shares of the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

1 Year
3 Years
5 Years
10 Years
$49 $154 $269 $604

Portfolio Turnover. The Fund may pay transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 4% of the average value of its portfolio.

Principal Investment Strategies

The Underlying Index is a free float-adjusted market capitalization-weighted index designed to measure the combined equity market performance of the consumer staples sector of developed and emerging markets countries, excluding the United States. Component securities include those of food and staples retailers, food, beverage and tobacco producers and household products manufacturer companies. As of September 30, 2011, the Underlying Index consisted of companies in the following countries and regions: Australia, Austria, Belgium, Brazil, Canada, Chile, China, Colombia, the Czech Republic, Denmark, Egypt, Finland, France, Germany, Greece, Hong Kong, Hungary, India, Indonesia, Ireland, Israel, Italy, Japan, Malaysia, Mexico, Morocco, the Netherlands, New Zealand, Norway, Peru, the Philippines, Poland, Portugal, Russia, Singapore, South Africa, South Korea, Spain, Sweden, Switzerland, Taiwan, Thailand, Turkey and the United Kingdom (together, the “ACWI ex US consumer staples sector countries”). As of September 30, 2011, the Underlying Index was comprised of 140 securities.

BFA uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to “beat” the index it tracks and does not seek temporary defensive positions when markets decline or appear overvalued.

Indexing may eliminate the chance that the Fund will substantially outperform the Underlying Index but also may reduce some of the risks of active management, such as poor security selection. Indexing seeks to achieve lower costs and better after-tax performance by keeping portfolio turnover low in comparison to actively managed investment companies.

BFA uses a representative sampling indexing strategy to manage the Fund. “Representative sampling” is an indexing strategy that involves investing in a representative sample of securities that collectively has an investment profile similar to the Underlying Index. The securities selected are expected to have, in the aggregate, investment characteristics (based on factors such as market capitalization and industry weightings), fundamental characteristics (such as return variability and yield) and liquidity measures similar to those of the Underlying Index. The Fund may or may not hold all of the securities in the Underlying Index.

The Fund generally invests at least 80% of its assets in securities of the Underlying Index or in depositary receipts representing securities of the Underlying Index. The Fund may invest the remainder of its assets in securities not included in the Underlying Index,

but which BFA believes will help the Fund track the Underlying Index and in other investments including futures contracts, options on futures contracts, options and swaps related to the Underlying Index, as well as cash and cash equivalents, including shares of money market funds advised by BFA or its affiliates.

The Fund may lend securities representing up to one-third of the value of the Fund’s total assets (including the value of the collateral received).

The Underlying Index is sponsored by an organization (the “Index Provider”) that is independent of the Fund and BFA. The Index Provider determines the composition and relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index. The Fund’s Index Provider is MSCI Inc. (“MSCI”).

Industry Concentration Policy. The Fund will concentrate its investments (i.e., hold 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. For purposes of this limitation, securities of the U.S. government (including its agencies and instrumentalities) and repurchase agreements collateralized by U.S. government securities are not considered to be issued by members of any industry.

Summary of Principal Risks

As with any investment, you could lose all or part of your investment in the Fund, and the Fund’s performance could trail that of other investments. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund’s net asset value per share (“NAV”), trading price, yield, total return and ability to meet its investment objective.

Asset Class Risk. Securities in the Underlying Index or in the Fund’s portfolio may underperform in comparison to the general securities markets or other asset classes.

Concentration Risk. To the extent that the Fund’s investments are concentrated in a particular issuer, region, country, market, industry or asset class, the Fund may be susceptible to loss due to adverse occurrences affecting that issuer, region, country, market, industry or asset class.

Consumer Discretionary Sector Risk. The consumer discretionary sector may be affected by changes in domestic and international economies, exchange and interest rates, competition, consumers’ disposable income and consumer preferences, social trends and marketing campaigns.

Consumer Goods Sector Risk. The consumer goods sector may be affected by changes in social trends and consumer demands. Many consumer goods are sold internationally and such companies are subject to market conditions in other countries and regions.

Consumer Staples Sector Risk. The consumer staples sector may be affected by marketing campaigns, changes in consumer demands, government regulations and changes in commodity prices.

Currency Risk. Because the Fund’s NAV is determined in U.S. dollars, the Fund’s NAV could decline if the currency

of a non-U.S. market in which the Fund invests depreciates against the U.S. dollar.

Custody Risk. Less developed markets are more likely to experience problems with the clearing and settling of trades and the holding of securities by local banks, agents and depositories.

Emerging Markets Risk. The Fund’s investments in emerging markets may be subject to a greater risk of loss than investments in more developed markets. Emerging markets may be more likely to experience inflation risk, political turmoil and rapid changes in economic conditions than more developed markets. Emerging markets often have less uniformity in accounting and reporting requirements, unreliable securities valuation and greater risk associated with custody of securities.

Equity Securities Risk. Equity securities are subject to changes in value and their values may be more volatile than other asset classes.

Geographic Risk. A natural or other disaster could occur in a geographic region in which the Fund invests, which could affect the economy or particular business operations of companies in the specific geographic region, causing an adverse impact on the Fund’s investments in the affected region.

Issuer Risk. Fund performance depends on the performance of individual securities to which the Fund has exposure. Changes to the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA’s investment management strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares, losses from trading in secondary markets, periods of high volatility and disruption in the creation/redemption process of the Fund. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV.

Mid-Capitalization Companies Risk. The Fund may invest in the securities of mid-capitalization companies. Compared to large-capitalization companies, mid-capitalization companies may be less stable and more susceptible to adverse developments and their securities may be more volatile and less liquid.

Non-Diversification Risk. The Fund may invest a large percentage of its assets in securities issued by or representing a small number of issuers. As a result, the Fund’s performance may depend on the performance of a small number of issuers.

Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers are subject to the risks associated with investing in those non-U.S. markets, such as heightened risks of inflation or nationalization. The Fund may lose money due to political, economic and geographic events affecting a non-U.S. issuer or market. The Fund is specifically exposed to European Economic Risk.

Passive Investment Risk. The Fund is not actively managed and BFA does not attempt to take defensive positions under any market conditions, including declining markets.

Privatization Risk. Some countries in which the Fund invests have begun a process of privatizing certain entities and industries. Privatized entities may lose money or be re-nationalized.

Reliance on Trading Partners Risk. The Fund invests in countries whose economies are heavily dependent upon trading with key partners. Any reduction in this trading may have an adverse impact on the Fund’s investments. Through its trading partners, the Fund is particularly exposed to U.S. Trading Partner Risk.

Securities Lending Risk. The Fund may engage in securities lending. Securities lending involves the risk that the Fund may lose money because the borrower of the Fund’s loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Security Risk. Some countries and regions in which the Fund invests have experienced security concerns. Incidents involving a country’s or region’s security may cause uncertainty in these markets and may adversely affect their economies and the Fund’s investments.

Structural Risk. The countries in which the Fund invests may be subject to considerable degrees of economic, political and social instability.

Tracking Error Risk. The performance of the Fund may diverge from that of the Underlying Index. Because the Fund employs a representative sampling strategy, the Fund may experience tracking error to a greater extent than a fund that seeks to replicate an index.

Valuation Risk. The value of the securities in the Fund’s portfolio may change on days when shareholders will not be able to purchase or sell the Fund’s shares.

Performance Information

As of the date of the Fund’s prospectus (the “Prospectus”), the Fund has been in operation for less than one full calendar year and therefore does not report its performance information.

Management

Investment Adviser. BlackRock Fund Advisors.

Portfolio Managers. Rene Casis, Diane Hsiung and Greg Savage (the “Portfolio Managers”) are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager supervises a portfolio management team. Mr. Casis has been a Portfolio Manager of the Fund since 2010. Ms. Hsiung and Mr. Savage have been Portfolio Managers of the Fund since inception.

Purchase and Sale of Fund Shares

The Fund is an exchange-traded fund (commonly referred to as an “ETF”). Individual Fund shares may only be purchased and sold on a national securities exchange through a broker-dealer. The price of Fund shares is based on market price, and because ETF shares trade at market prices rather than NAV, shares may trade at a price greater than NAV (a premium) or less than NAV (a discount). The Fund will only issue or redeem shares that have been aggregated into blocks of 50,000 shares or multiples thereof (“Creation Units”) to authorized participants who have entered into agreements with the Fund’s distributor. The Fund generally will issue or redeem Creation Units in return for a designated portfolio of securities (and an amount of cash) that the Fund specifies each day.

Tax Information

The Fund intends to make distributions that may be taxable to you as ordinary income or capital gains, unless you are investing through a tax-deferred arrangement such as a 401(k) plan or an individual retirement account (“IRA”).

Payments to Broker-Dealers and other Financial Intermediaries

If you purchase shares of the Fund through a broker-dealer or other financial intermediary (such as a bank), BFA or other related companies may pay the intermediary for marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems or other services related to the sale or promotion of the Fund. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.

More Information About the Fund

This Prospectus contains important information about investing in the Fund. Please read this Prospectus carefully before you make any investment decisions. Additional information regarding the Fund is available at www.iShares.com.

BFA is the investment adviser to the Fund. Shares of the Fund are listed for trading on NYSE Arca, Inc. (“NYSE Arca”). The market price for a share of the Fund may be different from the Fund’s most recent NAV.

ETFs are funds that trade like other publicly-traded securities. The Fund is designed to track an index. Similar to shares of an index mutual fund, each share of the Fund represents a partial ownership in an underlying portfolio of securities intended to track a market index. Unlike shares of a mutual fund, which can be bought and redeemed from the issuing fund by all shareholders at a price based on NAV, shares of the Fund may be purchased or redeemed directly from the Fund at NAV solely by authorized participants. Also unlike shares of a mutual fund, shares of the Fund are listed on a national securities exchange and trade in the secondary market at market prices that change throughout the day.

The Fund invests in a particular segment of the securities markets and seeks to track the performance of a securities index that generally is not representative of the market as a whole. The Fund is designed to be used as part of broader asset allocation strategies. Accordingly, an investment in the Fund should not constitute a complete investment program.

An index is a theoretical financial calculation while the Fund is an actual investment portfolio. The performance of the Fund and the Underlying Index may vary due to transaction costs, non-U.S. currency valuations, asset valuations, corporate actions (such as mergers and spin-offs), timing variances and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions (such as diversification requirements) that apply to the Fund but not to the Underlying Index or to the use of representative sampling. “Tracking error” is the difference between the performance (return) of the Fund’s portfolio and that of the Underlying Index. BFA expects that, over time, the Fund’s tracking error will not exceed 5%. Because the Fund uses a representative sampling indexing strategy, it can be expected to have a larger tracking error than if it used a replication indexing strategy. “Replication” is an indexing strategy in which a fund invests in substantially all of the securities in its underlying index in approximately the same proportions as in the underlying index.

An investment in the Fund is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, BFA or any of its affiliates.

The Fund’s investment objective and the Underlying Index may be changed without shareholder approval.

A Further Discussion of Principal Risks

The Fund is subject to various risks, including the principal risks noted below, any of which may adversely affect the Fund’s NAV, trading price, yield, total return and ability to meet its investment objective. You could lose all or part of your investment in the Fund, and the Fund could underperform other investments.

Asset Class Risk. The securities in the Underlying Index or in the Fund’s portfolio may underperform the returns of other securities or indexes that track other countries, groups of countries, regions, industries, groups of industries, markets, asset classes or sectors. Various types of securities or indexes tend to experience cycles of outperformance and underperformance in comparison to the general securities markets.

Concentration Risk. To the extent that the Fund’s portfolio reflects the Underlying Index’s concentration in the securities of a particular issuer or issuers in a particular country, group of countries, region, market, industry, group of industries, sector or asset class, the Fund may be adversely affected by the performance of those securities, may be subject to increased price volatility and may be more susceptible to adverse economic, market, political or regulatory occurrences affecting that issuer, country, group of countries, region, market, industry, group of industries, sector or asset class.

Consumer Discretionary Sector Risk. The success of consumer product manufacturers and retailers is tied closely to the performance of domestic and international economies, interest rates, exchange rates, competition, consumer confidence, changes in demographics and consumer preferences. Companies in the consumer discretionary sector depend heavily on disposable household income and consumer spending, and may be strongly affected by social trends and marketing campaigns. These companies may be subject to severe competition, which may have an adverse impact on their profitability.

Consumer Goods Sector Risk. The consumer goods sector may be strongly affected by social trends, marketing campaigns and other factors affecting consumer demand. Governmental regulation affecting the use of various food additives may affect the profitability of certain companies represented in the Underlying Index. In addition, tobacco companies may be adversely affected by new laws, regulations and litigation. Many consumer goods in the United States may also be marketed globally, and such consumer goods companies may be affected by the demand and market conditions in non-U.S. countries.

Consumer Staples Sector Risk. The Fund invests in companies in the consumer staples sector. The consumer staples sector may be affected by the permissibility of using various food additives and production methods, marketing campaigns and other factors affecting consumer demand. Tobacco companies, in particular, may be adversely affected by new laws, regulations and litigation. The consumer staples sector may also be adversely affected by changes or trends in commodity prices, which may be influenced or characterized by unpredictable factors.

Currency Risk. Because the Fund’s NAV is determined on the basis of the U.S. dollar, investors may lose money if the currency of a non-U.S. market in which the Fund

invests depreciates against the U.S. dollar, even if the local currency value of the Fund’s holdings in that market increases.



Custody Risk. Custody risk refers to the risks inherent in the process of clearing and settling trades and the holding of securities by local banks, agents and depositories. Low trading volumes and volatile prices in less developed markets may make trades harder to complete and settle, and governments or trade groups may compel local agents to hold securities in designated depositories that are not subject to independent evaluation. Local agents are held only to the standards of care of their local markets. In general, the less developed a country’s securities market is, the greater the likelihood of custody problems.

Emerging Markets Risk. Investments in emerging markets are subject to a greater risk of loss than investments in more developed markets. This is due to, among other things, the potential for greater market volatility, lower trading volume, inflation, political and economic instability, greater risk of a market shutdown and more governmental limitations on foreign investments than typically found in more developed markets. In addition, emerging markets often have less uniformity in accounting and reporting requirements, unreliable securities valuation and greater risks associated with custody of securities.

Equity Securities Risk. The Fund invests in equity securities, which are subject to changes in value that may be attributable to market perception of a particular issuer or to general stock market fluctuations that affect all issuers. Investments in equity securities may be more volatile than investments in other asset classes.

European Economic Risk. The Economic and Monetary Union of the European Union (the “EU”) requires member countries to comply with restrictions on inflation rates, deficits, interest rates, debt levels and fiscal and monetary controls, each of which may significantly affect every country in Europe. Decreasing imports or exports, changes in governmental or EU regulations on trade, changes in the exchange rate of the euro, the default or threat of default by an EU member country on its sovereign debt, and/or an economic recession in an EU member country may have a significant adverse effect on the economies of EU member countries and their trading partners, including some or all of the ACWI ex US consumer staples sector countries. The European financial markets have recently experienced volatility and have been adversely affected by concerns about economic downturns, credit rating downgrades, rising government debt levels and possible default on or restructuring of government debt in several European countries, including Greece, Ireland, Italy, Portugal and Spain. A default or debt restructuring by any European country would adversely impact holders of that country’s debt, and sellers of credit default swaps linked to that country’s creditworthiness, which may be located in countries other than those listed in the previous sentence. These events have adversely affected the value and exchange rate of the euro and may continue to significantly affect the economies of every country in Europe, including EU member countries that do not use the euro and non-EU member countries.

Geographic Risk. Some markets in which the Fund invests are located in parts of the world that have historically been prone to natural disasters, such as earthquakes, volcanoes, droughts, floods, hurricanes and tsunamis, and are economically sensitive

to environmental events. Any natural or other disaster could have a significant adverse impact on the economies of these geographic areas, causing an adverse impact on the Fund’s investments in the affected region.

Issuer Risk. The performance of the Fund depends on the performance of individual securities to which the Fund has exposure. Any issuer of these securities may perform poorly, causing the value of its securities to decline. Poor performance may be caused by poor management decisions, competitive pressures, changes in technology, expiration of patent protection, disruptions in supply, labor problems or shortages, corporate restructurings, fraudulent disclosures or other factors. Issuers may, in times of distress or at their own discretion, decide to reduce or eliminate dividends, which may also cause their stock prices to decline.

Management Risk. The Fund may not fully replicate the Underlying Index and may hold securities not included in the Underlying Index. As a result, the Fund is subject to the risk that BFA’s investment management strategy, the implementation of which is subject to a number of constraints, may not produce the intended results.

Market Risk. The Fund could lose money due to short-term market movements and over longer periods during market downturns. Securities may decline in value due to factors affecting securities markets generally or particular industries represented in the markets. The value of a security may decline due to general market conditions, economic trends or events that are not specifically related to the issuer of the security or to factors that affect a particular industry or industries. During a general downturn in the securities markets, multiple asset classes may be negatively affected.

Market Trading Risk

Absence of Active Market. Although shares of the Fund are listed for trading on one or more stock exchanges, there can be no assurance that an active trading market for such shares will develop or be maintained.

Risk of Secondary Listings. The Fund’s shares may be listed or traded on U.S. and non-U.S. stock exchanges other than the U.S. stock exchange where the Fund’s primary listing is maintained. There can be no assurance that the Fund’s shares will continue to trade on any such stock exchange or in any market or that the Fund’s shares will continue to meet the requirements for listing or trading on any exchange or in any market. The Fund’s shares may be less actively traded in certain markets than others, and investors are subject to the execution and settlement risks and market standards of the market where they or their broker direct their trades for execution. Certain information available to investors who trade Fund shares on a U.S. stock exchange during regular U.S. market hours may not be available to investors who trade in other markets, which may result in secondary market prices in such markets being less efficient.

Secondary Market Trading Risk. Shares of the Fund may trade in the secondary market at times when the Fund does not accept orders to purchase or redeem shares. At such times, shares may trade in the secondary market with more significant premiums or discounts than might be experienced at times when the Fund accepts purchase and redemption orders.

Secondary market trading in Fund shares may be halted by a stock exchange because of market conditions or other reasons. In addition, trading in Fund shares on a stock exchange or in any market may be subject to trading halts caused by extraordinary market volatility pursuant to “circuit breaker” rules on the stock exchange or market. There can be no assurance that the requirements necessary to maintain the listing or trading of Fund shares will continue to be met or will remain unchanged.

Shares of the Fund May Trade at Prices Other Than NAV. Shares of the Fund trade on stock exchanges at prices at, above or below their most recent NAV. The NAV of the Fund is calculated at the end of each business day and fluctuates with changes in the market value of the Fund’s holdings since the most recent calculation. The trading prices of the Fund’s shares fluctuate continuously throughout trading hours based on market supply and demand rather than NAV. The trading prices of the Fund’s shares may deviate significantly from NAV during periods of market volatility. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV. However, because shares can be created and redeemed in Creation Units at NAV (unlike shares of many closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their NAVs), BFA believes that large discounts or premiums to the NAV of the Fund are not likely to be sustained over the long-term. While the creation/redemption feature is designed to make it likely that the Fund’s shares normally will trade on stock exchanges at prices close to the Fund’s next calculated NAV, exchange prices are not expected to correlate exactly with the Fund’s NAV due to timing reasons as well as market supply and demand factors. In addition, disruptions to creations and redemptions or extreme market volatility may result in trading prices for shares of the Fund that differ significantly from its NAV.

Costs of Buying or Selling Fund Shares. Buying or selling Fund shares on an exchange involves two types of costs that apply to all securities transactions. When buying or selling shares of the Fund through a broker, you will likely incur a brokerage commission or other charges imposed by brokers as determined by that broker. In addition, you may incur the cost of the “spread” – that is, the difference between what investors are willing to pay for Fund shares (the “bid” price) and the price at which they are willing to sell Fund shares (the “ask” price). Because of the costs inherent in buying or selling Fund shares, frequent trading may detract significantly from investment results and an investment in Fund shares may not be advisable for investors who anticipate regularly making small investments.

Mid-Capitalization Companies Risk. Many of the companies in which the Fund invests are considered mid-capitalization companies. Stock prices of mid-capitalization companies may be more volatile than those of large-capitalization companies and, therefore, the Fund’s share price may be more volatile than those of funds that invest a larger percentage of their assets in stocks issued by large-capitalization companies. Stock prices of mid-capitalization companies are also more vulnerable than those of large-capitalization companies to adverse business or economic developments, and the stocks of mid-capitalization companies may be less liquid, making it difficult for the Fund to buy and sell them. In addition, mid-capitalization companies generally have

less diverse product lines than large-capitalization companies and are more susceptible to adverse developments related to their products.

Non-Diversification Risk. The Fund is classified as “non-diversified.” This means that the Fund may invest a large percentage of its assets in securities issued by or representing a small number of issuers. As a result, the Fund may be more susceptible to the risks associated with these particular issuers, or to a single economic, political or regulatory occurrence affecting these issuers.

Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers are subject to all of the risks of investing in the markets where such issuers are located, including heightened risks of inflation or nationalization and market fluctuations caused by economic and political developments. As a result of investing in non-U.S. securities, the Fund may be subject to increased risk of loss caused by any of the factors listed below:

  • Lower levels of liquidity and market efficiency;
  • Greater securities price volatility;
  • Exchange rate fluctuations and exchange controls;
  • Less availability of public information about issuers;
  • Limitations on foreign ownership of securities;
  • Imposition of withholding or other taxes;
  • Imposition of restrictions on the expatriation of the funds or other assets of the Fund;
  • Higher transaction and custody costs and delays in settlement procedures;
  • Difficulties in enforcing contractual obligations;
  • Lower levels of regulation of the securities market;
  • Weaker accounting, disclosure and reporting requirements; and
  • Legal principles related to corporate governance, directors’ fiduciary duties and liabilities and stockholders’ rights in markets in which the Fund invests may differ and/or may not be as extensive or protective as those that apply in the United States.

Passive Investment Risk. The Fund is not actively managed and may be affected by a general decline in market segments related to the Underlying Index. The Fund invests in securities included in, or representative of, the Underlying Index regardless of their investment merits. BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

Privatization Risk. Some countries in which the Fund invests have begun a process of privatizing certain entities and industries. In some instances, investors in newly privatized entities have suffered losses due to the inability of the newly privatized entities to adjust quickly to a competitive environment or changing regulatory and legal standards or, in some cases, due to re-nationalization of such privatized entities. There is no assurance that such losses will not recur.

Reliance on Trading Partners Risk. The economies of the ACWI ex US consumer staples sector countries are dependent on each other and on the United States as key trading partners. Reduction in spending on the products and services of the ACWI ex US consumer staples sector countries by any of their key trading partners, institution of tariffs or other trade barriers or a slowdown in the economies of any of their key trading partners may cause an adverse impact on the economies of the ACWI ex US consumer staples sector countries.

U.S. Trading Partners Risk. The United States is a significant, and in some cases the most significant, trading partner of or foreign investor in certain ACWI ex US consumer staples sector countries and the economies of these countries may be particularly affected by changes in the U.S. economy. Decreasing U.S. imports, new trade regulations, changes in the U.S. dollar exchange rate or a recession in the United States may have a material adverse effect on the economies of ACWI ex US consumer staples sector countries.

Securities Lending Risk. The Fund may engage in securities lending. Securities lending involves the risk that the Fund may lose money because the borrower of the Fund’s loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for the loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Security Risk. Some geographic areas in which the Fund invests have experienced acts of terrorism or strained international relations due to territorial disputes, historical animosities or other defense concerns. These situations may cause uncertainty in the markets of these geographic areas and may adversely affect the performance of their economies.

Structural Risk. Certain political, economic, legal and currency risks have contributed to a high degree of price volatility in the equity markets of the ACWI ex US consumer staples sector countries and could adversely affect investments in the Fund:

Political and Social Risk. Disparities of wealth, the pace and success of democratization and ethnic, religious and racial disaffection, among other factors, have led to social unrest, violence and labor unrest in some ACWI ex US consumer staples sector countries. Unanticipated or sudden political or social developments may result in sudden and significant investment losses.

Economic Risk. Some ACWI ex US consumer staples sector countries may experience economic instability, including instability resulting from substantial rates of inflation or significant devaluations of their currency, or economic recessions causing a negative effect on the economies and securities markets of their economies. Some of these countries may also impose restrictions on the exchange or export of currency or adverse currency exchange rates and may be characterized by a lack of available currency hedging instruments.

Expropriation and/or Nationalization Risk. Investments in certain ACWI ex US consumer staples sector countries may be subject to loss due to expropriation or

nationalization of assets and property or the imposition of restrictions on foreign investments and repatriation of capital.

Large Government Debt Risk. Chronic structural public sector deficits in some ACWI ex US consumer staples sector countries may adversely impact investments in the Fund.

Tracking Error Risk. Imperfect correlation between the Fund’s portfolio securities and those in the Underlying Index, rounding of prices, changes to the Underlying Index and regulatory requirements may cause tracking error, which is the divergence of the Fund’s performance from that of the Underlying Index. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Underlying Index does not. Because the Fund employs a representative sampling strategy, the Fund may experience tracking error to a greater extent than a fund that seeks to replicate an index.

Valuation Risk. Because non-U.S. exchanges may be open on days when the Fund does not price its shares, the value of the securities in the Fund’s portfolio may change on days when shareholders will not be able to purchase or sell the Fund’s shares. In addition, for purposes of calculating the Fund’s NAV, the value of assets denominated in non-U.S. currencies is converted into U.S. dollars using exchange rates deemed appropriate by BFA. This conversion may result in a difference between the prices used to calculate the Fund’s NAV and the prices used by the Underlying Index, which, in turn, could result in a difference between the Fund’s performance and the performance of the Underlying Index.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

Asian Economic Risk. Certain Asian economies have experienced over-extension of credit, currency devaluations and restrictions, high unemployment, high inflation, decreased exports and economic recessions. Economic events in any one Asian country may have a significant economic effect on the entire Asian region, as well as on major trading partners outside Asia, and any adverse event in the Asian markets may have a significant adverse effect on some or all of the ACWI ex US consumer staples sector countries.

Australasian Economic Risk. The economies of Australasia, which include Australia and New Zealand, are dependent on exports from the agricultural and mining sectors. This makes Australasian economies susceptible to fluctuations in the commodity markets. Australasian economies are also increasingly dependent on their growing service industries. Because the economies of Australasia are dependent on the economies of Asia, Europe and the United States as key trading partners and investors, reduction in spending by any of these trading partners on Australasian products and services, or negative changes in any of these economies, may cause an adverse impact on some or all of the Australasian economies.

North American Economic Risk. The United States is Canada’s and Mexico’s largest trading and investment partner. The Canadian and Mexican economies are significantly

affected by developments in the U.S. economy. Since the implementation of the North American Free Trade Agreement (“NAFTA”) in 1994 among Canada, the United States and Mexico, total merchandise trade between the three countries have increased. To further this relationship, the three NAFTA countries entered into the Security and Prosperity Partnership of North America in March 2005, which may further affect Canada’s and Mexico’s dependency on the U.S. economy. Economic events in any one North American country can have a significant economic effect on the entire North American region, and on some or all of the North American countries in which the Fund invests.

A description of the Trust’s policies and procedures with respect to the disclosure of the Fund’s portfolio securities is available in the Fund’s Statement of Additional Information (“SAI”). The top holdings of the Fund can be found at www.iShares.com. Fund fact sheets provide information regarding the Fund’s top holdings and may be requested by calling 1-800-iShares (1-800-474-2737).

Management

Investment Adviser. As investment adviser, BFA has overall responsibility for the general management and administration of the Trust. BFA provides an investment program for the Fund and manages the investment of the Fund’s assets. In managing the Fund, BFA may draw upon the research and expertise of its asset management affiliates with respect to certain portfolio securities. In seeking to achieve the Fund’s investment objective, BFA uses teams of portfolio managers, investment strategists and other investment specialists. This team approach brings together many disciplines and leverages BFA’s extensive resources.

Pursuant to the Investment Advisory Agreement between BFA and the Trust (entered into on behalf of the Fund), BFA is responsible for substantially all expenses of the Fund, except interest expenses, taxes, brokerage expenses, future distribution fees or expenses and extraordinary expenses.

For its investment advisory services to the Fund, BFA is entitled to receive a management fee from the Fund based on a percentage of the Fund’s average daily net assets, at the annual rate of 0.48%.

BFA is located at 400 Howard Street, San Francisco, CA 94105. It is a wholly owned subsidiary of BTC, which in turn is indirectly wholly-owned by BlackRock, Inc. (“BlackRock”). As of September 30, 2011, BTC and its affiliates, including BFA and BlackRock, provided investment advisory services for assets in excess of $3.35 trillion. BFA, BTC, BlackRock Execution Services, BlackRock and their affiliates deal, trade and invest for their own accounts in the types of securities in which the Fund may also invest.

A discussion regarding the basis for the Trust’s Board of Trustees’ (the “Board”) approval of the Investment Advisory Agreement with BFA is available in the Fund’s annual report for the period ended July 31.

Portfolio Managers. Rene Casis, Diane Hsiung and Greg Savage are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager is responsible for various functions related to portfolio management, including, but not limited to, investing cash inflows, coordinating with members of his or her portfolio management team to focus on certain asset classes, implementing investment strategy, researching and reviewing investment strategy and overseeing members of his or her portfolio management team that have more limited responsibilities.

Rene Casis has been employed by BFA (formerly, Barclays Global Fund Advisors (“BGFA”)) and BTC (formerly, Barclays Global Investors, N.A. (“BGI”)) as a senior portfolio manager since 2009. From 2005 to 2009, Mr. Casis was a trader at Barclays Capital. Prior to that, Mr. Casis was a portfolio manager from 2000 to 2005 for BGFA and BGI. Mr. Casis has been a Portfolio Manager of the Fund since 2010.

Diane Hsiung has been employed by BFA and BTC as a senior portfolio manager since 2007. Prior to that, Ms. Hsiung was a portfolio manager from 2002 to 2006 for BGFA and BGI. Ms. Hsiung has been a Portfolio Manager of the Fund since inception.

Greg Savage has been employed by BFA and BTC as a senior portfolio manager since 2006. Prior to that, Mr. Savage was a portfolio manager from 2001 to 2006 for BGFA and BGI. Mr. Savage has been a Portfolio Manager of the Fund since inception.

The Fund’s SAI provides additional information about the Portfolio Managers’ compensation, other accounts managed by the Portfolio Managers and the Portfolio Managers’ ownership (if any) of shares in the Fund.

Administrator, Custodian and Transfer Agent. State Street Bank and Trust Company (“State Street”) is the administrator, custodian and transfer agent for the Fund.

Conflicts of Interest. BFA wants you to know that there are certain entities with which BFA has relationships that may give rise to conflicts of interest, or the appearance of conflicts of interest. These entities include the following: BFA’s affiliates (including BlackRock and The PNC Financial Services Group, Inc., and each of their affiliates, directors, partners, trustees, managing members, officers and employees (collectively, the “Affiliates”)) and BlackRock’s significant shareholder, Barclays Bank PLC and its affiliates, including Barclays PLC (each, an “Entity” and together, the “Entities”).

The activities of BFA, the Affiliates and the Entities in the management of, or their interest in, their own accounts and other accounts they manage, may present conflicts of interest that could disadvantage the Fund and the shareholders. BFA and its Affiliates or the Entities provide investment management services to other funds and discretionary managed accounts that may follow an investment program similar to that of the Fund. BFA, its Affiliates and the Entities are involved worldwide with a broad spectrum of financial services and asset management activities and may engage in the ordinary course of business in activities in which their interests or the interests of their clients may conflict with those of the Fund. BFA, one or more of the Affiliates or the Entities acts, or may act, as an investor, investment banker, research provider, investment manager, financier, underwriter, advisor, market maker, trader, prime broker, lender, agent or principal, and have other direct and indirect interests, in

securities, currencies and other instruments in which the Fund may directly or indirectly invest. Thus, it is likely that the Fund will have multiple business relationships with and will invest in, engage in transactions with, make voting decisions with respect to, or obtain services from, entities for which BFA, an Affiliate or an Entity performs or seeks to perform investment banking or other services.

BFA or one or more Affiliates or Entities may engage in proprietary trading and advise accounts and funds that have investment objectives similar to those of the Fund and/or that engage in and compete for transactions in the same types of securities, currencies and other instruments as the Fund, including in securities issued by other open-end and closed-end investment management companies, including investment companies that are affiliated with the Fund and BFA, to the extent permitted under the Investment Company Act of 1940, as amended (the “1940 Act”). The trading activities of BFA, these Affiliates and Entities are carried out without reference to positions held directly or indirectly by the Fund and may result in BFA, an Affiliate or an Entity having positions that are adverse to those of the Fund.

No Affiliate or Entity is under any obligation to share any investment opportunity, idea or strategy with the Fund. As a result, an Affiliate or an Entity may compete with the Fund for appropriate investment opportunities. As a result of this and several other factors, the results of the Fund’s investment activities may differ from those of an Affiliate or an Entity and of other accounts managed by an Affiliate or an Entity, and it is possible that the Fund could sustain losses during periods in which one or more Affiliates or Entities and other accounts achieve profits on their trading for proprietary or other accounts. The opposite result is also possible.

The Fund may, from time to time, enter into transactions in which BFA or an Affiliate’s or an Entity’s clients have an interest adverse to the Fund. Furthermore, transactions undertaken by Affiliate-advised clients may adversely impact the Fund. Transactions by one or more Affiliate- or Entity-advised clients or BFA may have the effect of diluting or otherwise disadvantaging the values, prices or investment strategies of the Fund.

An Entity may maintain securities indices as part of the product offerings. Index-based funds seek to track the performance of securities indices and may use the name of the index in the fund name. Index providers, including the Entities, may be paid licensing fees for use of their indices or index names. Entities will not be obligated to license their indices to BFA and its Affiliates, and BFA and its Affiliates will not be assured that the terms of any index licensing agreement with the Entities will be as favorable as those terms offered to other index licensees.

The Fund’s activities may be limited because of regulatory restrictions applicable to one or more Affiliates or Entities, and/or their internal policies designed to comply with such restrictions. In addition, the Fund may invest in securities of companies with which an Affiliate or an Entity has or is trying to develop investment banking relationships or in which an Affiliate or an Entity has significant debt or equity investments. The Fund also may invest in securities of companies for which an Affiliate or an Entity provides or may some day provide research coverage. An Affiliate or an Entity may have business relationships with and purchase or distribute or sell services or products from or to distributors, consultants or others who recommend the Fund or who engage in transactions with or for the Fund, and may receive compensation for

such services. The Fund may also make brokerage and other payments to Affiliates or Entities in connection with the Fund’s portfolio investment transactions.

Pursuant to a securities lending program approved by the Board, the Fund has retained an Affiliate of BFA to serve as the securities lending agent for the Fund to the extent that the Fund participates in the securities lending program. For these services, the lending agent may receive a fee from the Fund, including a fee based on the returns earned on the Fund’s investment of the cash received as collateral for any loaned securities. In addition, one or more Affiliates may be among the entities to which the Fund may lend its portfolio securities under the securities lending program.

The activities of BFA, the Affiliates or Entities may give rise to other conflicts of interest that could disadvantage the Fund and the shareholders. BFA has adopted policies and procedures designed to address these potential conflicts of interest. See the Fund’s SAI for further information.

Shareholder Information

Additional shareholder information, including how to buy and sell shares of the Fund, is available free of charge by calling toll-free: 1-800-iShares (1-800-474-2737) or visiting our website at www.iShares.com.

Buying and Selling Shares. Shares of the Fund may be acquired or redeemed directly from the Fund only in Creation Units or multiples thereof, as discussed in the Creations and Redemptions section of this Prospectus. Only an Authorized Participant (as defined in the Creations and Redemptions section) may engage in creation or redemption transactions directly with the Fund. Once created, shares of the Fund generally trade in the secondary market in amounts less than a Creation Unit.

Shares of the Fund are listed on a national securities exchange for trading during the trading day. Shares can be bought and sold throughout the trading day like shares of other publicly-traded companies. The Trust does not impose any minimum investment for shares of the Fund purchased on an exchange. The Fund’s shares trade under the trading symbol “AXSL.”

Buying or selling Fund shares on an exchange involves two types of costs that may apply to all securities transactions. When buying or selling shares of the Fund through a broker, you will likely incur a brokerage commission or other charges determined by your broker. The commission is frequently a fixed amount and may be a significant proportional cost for investors seeking to buy or sell small amounts of shares. In addition, you may incur the cost of the “spread” – that is, any difference between the bid price and the ask price. The spread varies over time for shares of the Fund based on the trading volume and market liquidity, and is generally lower if the Fund has a lot of trading volume and market liquidity, and higher if the Fund has little trading volume and market liquidity.

The Board has adopted a policy of not monitoring for frequent purchases and redemptions of Fund shares (“frequent trading”) that appear to attempt to take advantage of a potential arbitrage opportunity presented by a lag between a change in the value of the Fund’s portfolio securities after the close of the primary markets for the Fund’s portfolio securities and the reflection of that change in the Fund’s NAV

(“market timing”), because the Fund generally sells and redeems its shares directly through transactions that are in-kind and/or for cash, subject to the conditions described below under Creations and Redemptions. The Board has not adopted a policy of monitoring for other frequent trading activity because shares of the Fund are listed for trading on a national securities exchange.

The national securities exchange on which the Fund’s shares are listed is open for trading Monday through Friday and is closed on weekends and the following holidays: New Year’s Day, Martin Luther King, Jr. Day, Presidents’ Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day. The Fund’s primary listing exchange is NYSE Arca.

Section 12(d)(1) of the 1940 Act restricts investments by investment companies in the securities of other investment companies. Registered investment companies are permitted to invest in the Fund beyond the limits set forth in Section 12(d)(1), subject to certain terms and conditions set forth in SEC rules or in an SEC exemptive order issued to the Trust. In order for a registered investment company to invest in shares of the Fund beyond the limitations of Section 12(d)(1) pursuant to the exemptive relief obtained by the Trust, the registered investment company must enter into an agreement with the Trust.

Book Entry. Shares of the Fund are held in book-entry form, which means that no stock certificates are issued. The Depository Trust Company (“DTC”) or its nominee is the record owner of all outstanding shares of the Fund and is recognized as the owner of all shares for all purposes.

Investors owning shares of the Fund are beneficial owners as shown on the records of DTC or its participants. DTC serves as the securities depository for shares of the Fund. DTC participants include securities brokers and dealers, banks, trust companies, clearing corporations and other institutions that directly or indirectly maintain a custodial relationship with DTC. As a beneficial owner of shares, you are not entitled to receive physical delivery of stock certificates or to have shares registered in your name, and you are not considered a registered owner of shares. Therefore, to exercise any right as an owner of shares, you must rely upon the procedures of DTC and its participants. These procedures are the same as those that apply to any other securities that you hold in book-entry or “street name” form.

Share Prices. The trading prices of the Fund’s shares in the secondary market generally differ from the Fund’s daily NAV and are affected by market forces such as supply and demand, economic conditions and other factors. Information regarding the intraday value of shares of the Fund, also known as the “indicative optimized portfolio value” (“IOPV”), is disseminated every 15 seconds throughout the trading day by the national securities exchange on which the Fund’s shares are listed or by market data vendors or other information providers. The IOPV is based on the current market value of the securities and/or cash required to be deposited in exchange for a Creation Unit. The IOPV does not necessarily reflect the precise composition of the current portfolio of securities held by the Fund at a particular point in time or the best possible valuation of the current portfolio. Therefore, the IOPV should not be viewed as a “real-time” update of the Fund’s NAV, which is computed only once a day. The IOPV is generally determined by using both current market quotations and/or price quotations obtained

from broker-dealers that may trade in the portfolio securities held by the Fund. The quotations of certain Fund holdings may not be updated during U.S. trading hours if such holdings do not trade in the United States. The Fund is not involved in, or responsible for, the calculation or dissemination of the IOPV and makes no representation or warranty as to its accuracy.

Determination of Net Asset Value. The NAV of the Fund normally is determined once daily Monday through Friday, generally as of the regularly scheduled close of business of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m., Eastern time) on each day that the NYSE is open for trading, based on prices at the time of closing provided that (a) any Fund assets or liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers (as detailed below) and (b) U.S. fixed income assets may be valued as of the announced closing time for trading in fixed income instruments in a particular market or exchange. The NAV of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets held by the Fund, and its liabilities, are determined pursuant to valuation policies and procedures approved by the Board. The Fund’s assets and liabilities are valued primarily on the basis of market quotations.

Equity investments are valued at market value, which is generally determined using the last reported official closing price or last trading price on the exchange or market on which the security is primarily traded at the time of valuation.

The Fund invests in foreign securities. Foreign currency exchange rates are generally determined as of 4:00 p.m., London time. Foreign securities owned by the Fund may trade on weekends or other days when the Fund does not price its shares. As a result, the Fund’s NAV may change on days when Authorized Participants will not be able to purchase or redeem Fund shares.

Generally, trading in foreign securities, U.S. government securities, money market instruments and certain fixed-income securities is substantially completed each day at various times prior to the close of business on the NYSE. The values of such securities used in computing the NAV of the Fund are determined as of such times.

When market quotations are not readily available or are believed by BFA to be unreliable, the Fund’s investments are valued at fair value. Fair value determinations are made by BFA in accordance with policies and procedures approved by the Fund’s Board. BFA may conclude that a market quotation is not readily available or is unreliable if a security or other asset or liability does not have a price source due to its lack of liquidity, if a market quotation differs significantly from recent price quotations or otherwise no longer appears to reflect fair value, where the security or other asset or liability is thinly traded, or where there is a significant event subsequent to the most recent market quotation. A “significant event” is an event that, in the judgment of BFA, is likely to cause a material change to the closing market price of the asset or liability

held by the Fund. Foreign securities whose values are affected by volatility that occurs in U.S. markets on a trading day after the close of foreign securities markets may be fair valued.

Fair value represents a good faith approximation of the value of an asset or liability. The fair value of an asset or liability held by the Fund is the amount the Fund might reasonably expect to receive from the current sale of that asset or the cost to extinguish that liability in an arm’s-length transaction. Valuing the Fund’s investments using fair value pricing will result in prices that may differ from current market valuations and that may not be the price at which those investments could have been sold during the period in which the particular fair values were used. Use of fair value prices and certain current market valuations could result in a difference between the prices used to calculate the Fund’s NAV and the prices used by the Underlying Index, which, in turn, could result in a difference between the Fund’s performance and the performance of the Underlying Index.

The value of assets or liabilities denominated in non-U.S. currencies will be converted into U.S. dollars using exchange rates deemed appropriate by BFA as investment adviser. Use of a rate different from the rate used by the Index Provider may adversely affect the Fund’s ability to track the Underlying Index.

Dividends and Distributions

General Policies. Dividends from net investment income, if any, generally are declared and paid semi-annually by the Fund. Distributions of net realized securities gains, if any, generally are declared and paid once a year, but the Trust may make distributions on a more frequent basis for the Fund. The Trust reserves the right to declare special distributions if, in its reasonable discretion, such action is necessary or advisable to preserve its status as a regulated investment company (“RIC”) or to avoid imposition of income or excise taxes on undistributed income or realized gains.

Dividends and other distributions on shares of the Fund are distributed on a pro rata basis to beneficial owners of such shares. Dividend payments are made through DTC participants and indirect participants to beneficial owners then of record with proceeds received from the Fund.

Dividend Reinvestment Service. No dividend reinvestment service is provided by the Trust. Broker-dealers may make available the DTC book-entry Dividend Reinvestment Service for use by beneficial owners of the Fund for reinvestment of their dividend distributions. Beneficial owners should contact their broker to determine the availability and costs of the service and the details of participation therein. Brokers may require beneficial owners to adhere to specific procedures and timetables. If this service is available and used, dividend distributions of both income and realized gains will be automatically reinvested in additional whole shares of the Fund purchased in the secondary market.

Taxes. As with any investment, you should consider how your investment in shares of the Fund will be taxed. The tax information in this Prospectus is provided as general information, based on current law. You should consult your own tax professional about the tax consequences of an investment in shares of the Fund.

Unless your investment in Fund shares is made through a tax-exempt entity or tax-deferred retirement account, such as an IRA, you need to be aware of the possible tax consequences when the Fund makes distributions or you sell Fund shares.

Taxes on Distributions. Distributions from the Fund’s net investment income (other than qualified dividend income), including distributions of income from securities lending and distributions out of the Fund’s net short-term capital gains, if any, are taxable to you as ordinary income. Distributions by the Fund of net long-term capital gains in excess of net short-term capital losses (capital gain dividends) are taxable to you as long-term capital gains, generally at a 15% tax rate (0% at certain income levels), regardless of how long you have held the Fund’s shares. Distributions by the Fund that qualify as qualified dividend income are taxable to you at long-term capital gain rates for taxable years beginning on or before December 31, 2012. The 15% and 0% tax rates expire for taxable years beginning after December 31, 2012. Maximum long-term capital gain income tax rates are scheduled to rise to 20% in 2013. Beginning in 2013, a 3.8% U.S. federal Medicare contribution tax will be imposed on “net investment income,” including interest, dividends, and capital gains, of U.S. individuals with income exceeding $200,000 (or $250,000 if married and filing jointly), and of estates and trusts.

Dividends will be qualified dividend income to you if they are attributable to qualified dividend income received by the Fund. Generally, qualified dividend income includes dividend income from taxable U.S. corporations and qualified non-U.S. corporations, provided that the Fund satisfies certain holding period requirements in respect of the stock of such corporations and has not hedged its position in the stock in certain ways. Substitute dividends received by the Fund with respect to dividends paid on securities lent out will not be qualified dividend income. For this purpose, a qualified non-U.S. corporation means any non-U.S. corporation that is eligible for benefits under a comprehensive income tax treaty with the United States, which includes an exchange of information program or if the stock with respect to which the dividend was paid is readily tradable on an established United States securities market. The term excludes a corporation that is a passive foreign investment company.

Dividends received by the Fund from a real estate investment trust (“REIT”) or another RIC generally are qualified dividend income only to the extent the dividend distributions are made out of qualified dividend income received by such REIT or RIC. It is expected that dividends received by the Fund from a REIT and distributed to a shareholder generally will be taxable to the shareholder as ordinary income.

For a dividend to be treated as qualified dividend income, the dividend must be received with respect to a share of stock held without being hedged by the Fund, and with respect to a share of the Fund held without being hedged by you, for 61 days during the 121-day period beginning at the date which is 60 days before the date on which such share becomes ex-dividend with respect to such dividend or, in the case of certain preferred stock, 91 days during the 181-day period beginning 90 days before such date.

If your Fund shares are loaned out pursuant to a securities lending arrangement, you may lose the ability to use foreign tax credits passed through by the Fund or to treat Fund dividends paid while the shares are held by the borrower as qualified dividend income.

In general, your distributions are subject to U.S. federal income tax for the year when they are paid. Certain distributions paid in January, however, may be treated as paid on December 31 of the prior year.

If the Fund’s distributions exceed current and accumulated earnings and profits, all or a portion of the distributions made in the taxable year may be recharacterized as a return of capital to shareholders. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and result in a higher capital gain or lower capital loss when those shares on which the distribution was received are sold. Once a shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain, if the shareholder holds shares of the Fund as capital assets.

If you are neither a resident nor a citizen of the United States or if you are a non-U.S. entity, the Fund’s ordinary income dividends (which include distributions of net short-term capital gains) will generally be subject to a 30% U.S. withholding tax, unless a lower treaty rate applies, provided that withholding tax will generally not apply to any gain or income realized by a non-U.S. shareholder in respect of any distributions of long-term capital gains or upon the sale or other disposition of shares of the Fund.

A 30% withholding tax will be imposed on dividends paid after December 31, 2013, and redemption proceeds paid after December 31, 2014, to (i) foreign financial institutions including non-U.S. investment funds unless they agree to collect and disclose to the Internal Revenue Service (“IRS”) information regarding their direct and indirect U.S. account holders and (ii) certain other foreign entities, unless they certify certain information regarding their direct and indirect U.S. owners. To avoid withholding, foreign financial institutions will need to enter into agreements with the IRS that state that they will provide the IRS information, including the name, address and taxpayer identification number of direct and indirect U.S. account holders, comply with due diligence procedures with respect to the identification of U.S. accounts, report to the IRS certain information with respect to U.S. accounts maintained, agree to withhold tax on certain payments made to non-compliant foreign financial institutions or to account holders who fail to provide the required information, and determine certain other information as to their account holders. Other foreign entities will need to provide the name, address, and taxpayer identification number of each substantial U.S. owner or certifications of no substantial U.S. ownership unless certain exceptions apply.

Dividends, interest and capital gains earned by the Fund with respect to non-U.S. securities may give rise to withholding and other taxes imposed by non-U.S. countries. Tax conventions between certain countries and the United States may reduce or eliminate such taxes. If more than 50% of the total assets of the Fund at the close of a year consists of non-U.S. stocks or securities, the Fund may “pass through” to you certain non-U.S. income taxes (including withholding taxes) paid by the Fund. This means that you would be considered to have received as an additional dividend your share of such non-U.S. taxes, but you may be entitled to either a corresponding tax

deduction in calculating your taxable income, or, subject to certain limitations, a credit in calculating your U.S. federal income tax.

For purposes of foreign tax credits for U.S. shareholders of the Fund, foreign capital gains taxes may not produce associated foreign source income, thereby limiting a U.S. person’s ability to use such credits.

If you are a resident or a citizen of the United States, by law, back-up withholding will apply to your distributions and proceeds if you have not provided a taxpayer identification number or social security number and made other required certifications.

Taxes When Shares are Sold. Currently, any capital gain or loss realized upon a sale of Fund shares is generally treated as a long-term gain or loss if the shares have been held for more than one year. Any capital gain or loss realized upon a sale of Fund shares held for one year or less is generally treated as short-term gain or loss, except that any capital loss on the sale of shares held for six months or less is treated as long-term capital loss to the extent that capital gain dividends were paid with respect to such shares. Beginning in 2013, any such capital gains, including from sales of Fund shares or from capital gain dividends, will be included in “net investment income” for purposes of the 3.8% U.S. federal Medicare contribution tax mentioned above.

The foregoing discussion summarizes some of the consequences under current U.S. federal tax law of an investment in the Fund. It is not a substitute for personal tax advice. You may also be subject to state and local taxation on Fund distributions and sales of shares. Consult your personal tax adviser about the potential tax consequences of an investment in shares of the Fund under all applicable tax laws.

Creations and Redemptions. Prior to trading in the secondary market, shares of the Fund are “created” at NAV by market makers, large investors and institutions only in block-size Creation Units of 50,000 shares or multiples thereof. Each “creator” or “Authorized Participant” enters into an authorized participant agreement with the Fund’s distributor, SEI Investments Distribution Co. (the “Distributor”). Only an Authorized Participant may create or redeem Creation Units directly with the Fund. A creation transaction, which is subject to acceptance by the transfer agent, generally takes place when an Authorized Participant deposits into the Fund a designated portfolio of securities and a specified amount of cash approximating the holdings of the Fund in exchange for a specified number of Creation Units. To the extent practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund.

Similarly, shares can be redeemed only in Creation Units, generally for a designated portfolio of securities and a specified amount of cash held by the Fund (“Fund Securities”). Except when aggregated in Creation Units, shares are not redeemable by the Fund. The prices at which creations and redemptions occur are based on the next calculation of NAV after an order is received in a form described in the authorized participant agreement.

The Fund intends to comply with the U.S. federal securities laws in accepting securities for deposit and satisfying redemptions with redemption securities by, among other means, assuring that any securities accepted for deposit and any securities used to satisfy redemption requests will be sold in transactions that would be exempt from

registration under the Securities Act of 1933, as amended (the “1933 Act”). Further, an Authorized Participant that is not a “qualified institutional buyer,” as such term is defined under Rule 144A of the 1933 Act, will not be able to receive Fund Securities that are restricted securities eligible for resale under Rule 144A.

Creations and redemptions must be made through a firm that is either a member of the Continuous Net Settlement System of the National Securities Clearing Corporation or a DTC participant and has executed an agreement with the Distributor with respect to creations and redemptions of Creation Unit aggregations. Information about the procedures regarding creation and redemption of Creation Units (including the cut-off times for receipt of creation and redemption orders) is included in the Fund’s SAI.

Because new shares may be created and issued on an ongoing basis, at any point during the life of the Fund a “distribution,” as such term is used in the 1933 Act, may be occurring. Broker-dealers and other persons are cautioned that some activities on their part may, depending on the circumstances, result in their being deemed participants in a distribution in a manner that could render them statutory underwriters and subject to the prospectus delivery and liability provisions of the 1933 Act. Any determination of whether one is an underwriter must take into account all the relevant facts and circumstances of each particular case.

Broker-dealers should also note that dealers who are not “underwriters” but are participating in a distribution (as contrasted to ordinary secondary transactions), and thus dealing with shares that are part of an “unsold allotment” within the meaning of Section 4(3)(C) of the 1933 Act, would be unable to take advantage of the prospectus delivery exemption provided by Section 4(3) of the 1933 Act. For delivery of prospectuses to exchange members, the prospectus delivery mechanism of Rule 153 under the 1933 Act is available only with respect to transactions on a national securities exchange.

Costs Associated with Creations and Redemptions. Authorized Participants are charged standard creation and redemption transaction fees to offset transfer and other transaction costs associated with the issuance and redemption of Creation Units. The standard creation and redemption transaction fees are set forth in the table below. The standard creation transaction fee is charged to the Authorized Participant on the day such Authorized Participant creates a Creation Unit, and is the same regardless of the number of Creation Units purchased by the Authorized Participant on the applicable business day. Similarly, the standard redemption transaction fee is charged to the Authorized Participant on the day such Authorized Participant redeems a Creation Unit, and is the same regardless of the number of Creation Units redeemed by the Authorized Participant on the applicable business day. Creations and redemptions for cash (when cash creations and redemptions (in whole or in part) are available or specified) are also subject to an additional charge (up to the maximum amounts shown in the table below). This charge is intended to compensate for brokerage, tax, foreign exchange, execution, market impact and other costs and expenses related to cash transactions. Investors who use the services of a broker or other financial intermediary may pay fees for such services.

The following table shows, as of September 30, 2011, the approximate value of one Creation Unit, standard fees and maximum additional charges for creations and redemptions (as described above):

Householding. Householding is an option available to certain Fund investors. Householding is a method of delivery, based on the preference of the individual investor, in which a single copy of certain shareholder documents can be delivered to investors who share the same address, even if their accounts are registered under different names. Please contact your broker-dealer if you are interested in enrolling in householding and receiving a single copy of prospectuses and other shareholder documents, or if you are currently enrolled in householding and wish to change your householding status.

Distribution

The Distributor distributes Creation Units for the Fund on an agency basis. The Distributor does not maintain a secondary market in shares of the Fund. The Distributor has no role in determining the policies of the Fund or the securities that are purchased or sold by the Fund. The Distributor’s principal address is One Freedom Valley Drive, Oaks, PA 19456.

In addition, BFA or its Affiliates make payments to broker-dealers, banks or other financial intermediaries (together, “intermediaries”) related to marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems, or their making shares of the Fund and certain other iShares funds available to their customers. Such payments, which may be significant to the intermediary, are not made by the Fund. Rather, such payments are made by BFA or its Affiliates from their own resources, which come directly or indirectly in part from fees paid by the iShares funds complex. Payments of this type are sometimes referred to as revenue-sharing payments. A financial intermediary may make decisions about which investment options it recommends or makes available, or the level of services provided, to its customers based on the revenue-sharing payments it is eligible to receive. Therefore, such payments to an intermediary create conflicts of interest between the intermediary and its customers and may cause the intermediary to recommend the Fund or other iShares funds over another investment. More information regarding these payments is contained in the Fund’s SAI. Please contact your salesperson or other investment professional for more information regarding any such payments his or her firm may receive from BFA or its Affiliates.

Financial Highlights

The financial highlights table is intended to help investors understand the Fund’s financial performance since inception. Certain information reflects financial results for a single share of the Fund. The total returns in the table represent the rate that an investor would have earned (or lost) on an investment in the Fund, assuming reinvestment of all dividends and distributions. This information has been audited by PricewaterhouseCoopers LLP, whose report is included, along with the Fund’s financial statements, in the Fund’s Annual Report (available upon request).

Supplemental Information

I. Premium/Discount Information

The table that follows presents information about the differences between the daily market price on secondary markets for shares of the Fund and the Fund’s NAV. NAV is the price at which the Fund issues and redeems shares. It is calculated in accordance with the standard formula for valuing mutual fund shares. The price used to calculate market returns (“Market Price”) of the Fund generally is determined using the midpoint between the highest bid and the lowest offer on the primary securities exchange on which shares of the Fund are listed for trading, as of the time that the Fund’s NAV is calculated. The Fund’s Market Price may be at, above or below its NAV. The NAV of the Fund will fluctuate with changes in the value of its portfolio holdings. The Market Price of the Fund will fluctuate in accordance with changes in its NAV, as well as market supply and demand.

Premiums or discounts are the differences (expressed as a percentage) between the NAV and Market Price of the Fund on a given day, generally at the time the NAV is calculated. A premium is the amount that the Fund is trading above the reported NAV, expressed as a percentage of the NAV. A discount is the amount that the Fund is trading below the reported NAV, expressed as a percentage of the NAV.

The following information shows the frequency of distributions of premiums and discounts for the Fund from October 1, 2010 through September 30, 2011.

Each line in the table shows the number of trading days in which the Fund traded within the premium/discount range indicated. The number of trading days in each premium/discount range is also shown as a percentage of the total number of trading days in the period covered by the table. All data presented here represents past performance, which cannot be used to predict future results.

Premium/Discount Range
Number of Days
Percentage of Total Days
Greater than 1.5% and Less than 2.0% 1 0.40%
Greater than 1.0% and Less than 1.5% 5 1.98
Greater than 0.5% and Less than 1.0% 28 11.07

Less than -2.0% and Greater than -2.5% 2 0.79
Less than -2.5% and Greater than -3.0% 1 0.40
Less than -3.0% and Greater than -3.5% 1 0.40
   253 100.00%

II. Total Return Information

The table that follows presents information about the total returns of the Fund and the Underlying Index as of the fiscal year ended July 31, 2011.

“Average Annual Total Returns” represent the average annual change in value of an investment over the periods indicated. “Cumulative Total Returns” represent the total change in value of an investment over the period indicated.

The Fund’s NAV is the value of one share of the Fund as calculated in accordance with the standard formula for valuing mutual fund shares. The NAV return is based on the NAV of the Fund and the market return is based on the Market Price of the Fund. Market Price is determined by using the midpoint between the highest bid and the lowest offer on the primary stock exchange on which shares of the Fund are listed for trading, as of the time that the Fund’s NAV is calculated. Since shares of the Fund did not trade in the secondary market until after the Fund’s inception, for the period from inception to the first day of secondary market trading in shares of the Fund, the NAV of the Fund is used as a proxy for the Market Price to calculate market returns. Market and NAV returns assume that dividends and capital gain distributions have been reinvested in the Fund at Market Price and NAV, respectively.

An index is a statistical composite that tracks a specified financial market or sector. Unlike the Fund, the Underlying Index does not actually hold a portfolio of securities and therefore does not incur the expenses incurred by the Fund. These expenses negatively impact the performance of the Fund. Also, market returns do not include brokerage commissions that may be payable on secondary market transactions. If brokerage commissions were included, market returns would be lower. The returns shown in the following table do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption or sale of Fund shares. The investment return and principal value of shares of the Fund will vary with changes in market conditions. Shares of the Fund may be worth more or less than their original cost when they are redeemed or sold in the market. The Fund’s past performance is no guarantee of future results.

Fund Overview

iSHARES® MSCI ACWI ex US ENERGY SECTOR INDEX FUND

Ticker: AXEN Stock Exchange: NYSE Arca

Investment Objective

The iShares MSCI ACWI ex US Energy Sector Index Fund (the “Fund”) seeks investment results that correspond generally to the price and yield performance, before fees and expenses, of the MSCI All Country World ex USA Energy Index (the “Underlying Index”).

Fees and Expenses

The following table describes the fees and expenses that you will incur if you own shares of the Fund. The investment advisory agreement between iShares Trust (the “Trust”) and BlackRock Fund Advisors (“BFA”) (the “Investment Advisory Agreement”) provides that BFA will pay all operating expenses of the Fund, except interest expenses, taxes, brokerage expenses, future distribution fees or expenses, and extraordinary expenses.

You may also incur usual and customary brokerage commissions when buying or selling shares of the Fund, which are not reflected in the example that follows:

Annual Fund Operating Expenses

percentage of the value of your investments)

Expenses
0.48% None None 0.48%

Example. This Example is intended to help you compare the cost of owning shares of the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

1 Year
3 Years
5 Years
10 Years
$49 $154 $269 $604

Portfolio Turnover. The Fund may pay transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 7% of the average value of its portfolio.

Principal Investment Strategies

The Underlying Index is a free float-adjusted market capitalization-weighted index designed to measure the combined equity market performance of the energy sector of developed and emerging markets countries, excluding the United States. Component securities include those of energy equipment and services companies, and oil, gas and consumable fuel companies. As of September 30, 2011, the Underlying Index consisted of companies in the following countries or regions: Australia, Austria, Belgium, Brazil, Canada, Chile, China, Colombia, the Czech Republic, Denmark, Egypt, Finland, France, Germany, Greece, Hong Kong, Hungary, India, Indonesia, Ireland, Israel, Italy, Japan, Malaysia, Mexico, Morocco, the Netherlands, New Zealand, Norway, Peru, the Philippines, Poland, Portugal, Russia, Singapore, South Africa, South Korea, Spain, Sweden, Switzerland, Taiwan, Thailand, Turkey and the United Kingdom (together, the “ACWI ex US energy sector countries”). As of September 30, 2011, the Underlying Index was comprised of 116 securities.

BFA uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to “beat” the index it tracks and does not seek temporary defensive positions when markets decline or appear overvalued.

Indexing may eliminate the chance that the Fund will substantially outperform the Underlying Index but also may reduce some of the risks of active management, such as poor security selection. Indexing seeks to achieve lower costs and better after-tax performance by keeping portfolio turnover low in comparison to actively managed investment companies.

BFA uses a representative sampling indexing strategy to manage the Fund. “Representative sampling” is an indexing strategy that involves investing in a representative sample of securities that collectively has an investment profile similar to the Underlying Index. The securities selected are expected to have, in the aggregate, investment characteristics (based on factors such as market capitalization and industry weightings), fundamental characteristics (such as return variability and yield) and liquidity measures similar to those of the Underlying Index. The Fund may or may not hold all of the securities in the Underlying Index.

The Fund generally invests at least 80% of its assets in securities of the Underlying Index or in depositary receipts representing securities of the Underlying Index. The Fund may invest the remainder of its assets in securities not included in the Underlying Index,

S-2   


Table Of Contents



but which BFA believes will help the Fund track the Underlying Index and in other investments including futures contracts, options on futures contracts, options and swaps related to the Underlying Index, as well as cash and cash equivalents, including shares of money market funds advised by BFA or its affiliates.

The Fund may lend securities representing up to one-third of the value of the Fund’s total assets (including the value of the collateral received).

The Underlying Index is sponsored by an organization (the “Index Provider”) that is independent of the Fund and BFA. The Index Provider determines the composition and relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index. The Fund’s Index Provider is MSCI Inc. (“MSCI”).

Industry Concentration Policy. The Fund will concentrate its investments (i.e., hold 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. For purposes of this limitation, securities of the U.S. government (including its agencies and instrumentalities) and repurchase agreements collateralized by U.S. government securities are not considered to be issued by members of any industry.

Summary of Principal Risks

As with any investment, you could lose all or part of your investment in the Fund, and the Fund’s performance could trail that of other investments. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund’s net asset value per share (“NAV”), trading price, yield, total return and ability to meet its investment objective.

Asset Class Risk. Securities in the Underlying Index or in the Fund’s portfolio may underperform in comparison to the general securities markets or other asset classes.

Commodity Risk. The Fund invests in economies that are susceptible to fluctuations in certain commodity markets. Any negative changes in commodity markets could have an adverse impact on those economies.

Concentration Risk. To the extent that the Fund’s investments are concentrated in a particular issuer, region, country, market, industry or asset class, the Fund may be susceptible to loss due to adverse occurrences affecting that issuer, region, country, market, industry or asset class.

Currency Risk. Because the Fund’s NAV is determined in U.S. dollars, the Fund’s NAV could decline if the currency of a non-U.S. market in which the Fund invests depreciates against the U.S. dollar.

Custody Risk. Less developed markets are more likely to experience problems with the clearing and settling of trades and the holding of securities by local banks, agents and depositories.

Emerging Markets Risk. The Fund’s investments in emerging markets may be subject to a greater risk of loss than investments in more developed markets. Emerging markets may be more likely to experience inflation risk, political turmoil and rapid changes in economic conditions than more

S-3   


Table Of Contents



developed markets. Emerging markets often have less uniformity in accounting and reporting requirements, unreliable securities valuation and greater risk associated with custody of securities.

Energy Sector Risk. The value of securities issued by companies in the energy sector may decline for many reasons, including, without limitation, changes in commodity prices, government regulations, energy conservation efforts and potential civil liabilities.

Equity Securities Risk. Equity securities are subject to changes in value and their values may be more volatile than other asset classes.

Geographic Risk. A natural or other disaster could occur in a geographic region in which the Fund invests, which could affect the economy or particular business operations of companies in the specific geographic region, causing an adverse impact on the Fund’s investments in the affected region.

Issuer Risk. Fund performance depends on the performance of individual securities to which the Fund has exposure. Changes to the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA’s investment management strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares, losses from trading in secondary markets, periods of high volatility and disruption in the creation/redemption process of the Fund. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV.

Mid-Capitalization Companies Risk. The Fund may invest in the securities of mid-capitalization companies. Compared to large-capitalization companies, mid-capitalization companies may be less stable and more susceptible to adverse developments and their securities may be more volatile and less liquid.

Non-Diversification Risk. The Fund may invest a large percentage of its assets in securities issued by or representing a small number of issuers. As a result, the Fund’s performance may depend on the performance of a small number of issuers.

Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers are subject to the risks associated with investing in those non-U.S. markets, such as heightened risks of inflation or nationalization. The Fund may lose money due to political, economic and geographic events affecting a non-U.S. issuer or market. The Fund is specifically exposed to European Economic Risk.

Passive Investment Risk. The Fund is not actively managed and BFA does not attempt to take defensive positions under any market conditions, including declining markets.

Privatization Risk. Some countries in which the Fund invests have begun a process of privatizing certain entities

S-4   


Table Of Contents



and industries. Privatized entities may lose money or be re-nationalized.

Reliance on Trading Partners Risk. The Fund invests in countries whose economies are heavily dependent upon trading with key partners. Any reduction in this trading may have an adverse impact on the Fund’s investments. Through its trading partners, the Fund is particularly exposed to U.S. Trading Partner Risk.

Securities Lending Risk. The Fund may engage in securities lending. Securities lending involves the risk that the Fund may lose money because the borrower of the Fund’s loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Security Risk. Some countries and regions in which the Fund invests have experienced security concerns. Incidents involving a country’s or region’s security may cause uncertainty in these markets and may adversely affect their economies and the Fund’s investments.

Structural Risk. The countries in which the Fund invests may be subject to considerable degrees of economic, political and social instability.

Tracking Error Risk. The performance of the Fund may diverge from that of the Underlying Index. Because the Fund employs a representative sampling strategy, the Fund may experience tracking error to a greater extent than a fund that seeks to replicate an index.

Valuation Risk. The value of the securities in the Fund’s portfolio may change on days when shareholders will not be able to purchase or sell the Fund’s shares.

Performance Information

As of the date of the Fund’s prospectus (the “Prospectus”), the Fund has been in operation for less than one full calendar year and therefore does not report its performance information.

Management

Investment Adviser. BlackRock Fund Advisors.

Portfolio Managers. Rene Casis, Diane Hsiung and Greg Savage (the “Portfolio Managers”) are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager supervises a portfolio management team. Mr. Casis has been a Portfolio Manager of the Fund since 2010. Ms. Hsiung and Mr. Savage have been Portfolio Managers of the Fund since inception.

Purchase and Sale of Fund Shares

The Fund is an exchange-traded fund (commonly referred to as an “ETF”). Individual Fund shares may only be purchased and sold on a national securities exchange through a broker-dealer. The price of Fund shares is based on market price, and because ETF shares trade at market prices rather than NAV, shares may trade at a price greater than NAV (a premium) or less than NAV (a discount). The Fund will only issue or redeem shares that have been aggregated into blocks of 50,000 shares or multiples thereof (“Creation Units”) to authorized participants who have entered into agreements with the Fund’s distributor. The Fund generally will issue or redeem Creation Units in return for a designated portfolio of securities (and an amount of cash) that the Fund specifies each day.

Tax Information

The Fund intends to make distributions that may be taxable to you as ordinary income or capital gains, unless you are investing through a tax-deferred arrangement such as a 401(k) plan or an individual retirement account (“IRA”).

Payments to Broker-Dealers and other Financial Intermediaries

If you purchase shares of the Fund through a broker-dealer or other financial intermediary (such as a bank), BFA or other related companies may pay the intermediary for marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems or other services related to the sale or promotion of the Fund. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.

More Information About the Fund

This Prospectus contains important information about investing in the Fund. Please read this Prospectus carefully before you make any investment decisions. Additional information regarding the Fund is available at www.iShares.com.

BFA is the investment adviser to the Fund. Shares of the Fund are listed for trading on NYSE Arca, Inc. (“NYSE Arca”). The market price for a share of the Fund may be different from the Fund’s most recent NAV.

ETFs are funds that trade like other publicly-traded securities. The Fund is designed to track an index. Similar to shares of an index mutual fund, each share of the Fund represents a partial ownership in an underlying portfolio of securities intended to track a market index. Unlike shares of a mutual fund, which can be bought and redeemed from the issuing fund by all shareholders at a price based on NAV, shares of the Fund may be purchased or redeemed directly from the Fund at NAV solely by authorized participants. Also unlike shares of a mutual fund, shares of the Fund are listed on a national securities exchange and trade in the secondary market at market prices that change throughout the day.

The Fund invests in a particular segment of the securities markets and seeks to track the performance of a securities index that generally is not representative of the market as a whole. The Fund is designed to be used as part of broader asset allocation strategies. Accordingly, an investment in the Fund should not constitute a complete investment program.

An index is a theoretical financial calculation while the Fund is an actual investment portfolio. The performance of the Fund and the Underlying Index may vary due to transaction costs, non-U.S. currency valuations, asset valuations, corporate actions (such as mergers and spin-offs), timing variances and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions (such as diversification requirements) that apply to the Fund but not to the Underlying Index or to the use of representative sampling. “Tracking error” is the difference between the performance (return) of the Fund’s portfolio and that of the Underlying Index. BFA expects that, over time, the Fund’s tracking error will not exceed 5%. Because the Fund uses a representative sampling indexing strategy, it can be expected to have a larger tracking error than if it used a replication indexing strategy. “Replication” is an indexing strategy in which a fund invests in substantially all of the securities in its underlying index in approximately the same proportions as in the underlying index.

An investment in the Fund is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, BFA or any of its affiliates.

The Fund’s investment objective and the Underlying Index may be changed without shareholder approval.

A Further Discussion of Principal Risks

The Fund is subject to various risks, including the principal risks noted below, any of which may adversely affect the Fund’s NAV, trading price, yield, total return and ability to meet its investment objective. You could lose all or part of your investment in the Fund, and the Fund could underperform other investments.

Asset Class Risk. The securities in the Underlying Index or in the Fund’s portfolio may underperform the returns of other securities or indexes that track other countries, groups of countries, regions, industries, groups of industries, markets, asset classes or sectors. Various types of securities or indexes tend to experience cycles of outperformance and underperformance in comparison to the general securities markets.

Commodity Risk. Economies and companies whose performance is reflected in the Fund’s portfolio or Underlying Index may be adversely affected by changes or trends in commodity prices. Commodity prices may be influenced or characterized by unpredictable factors, including, where applicable, high volatility, changes in supply and demand relationships, weather, agriculture, trade, pestilence, political instability, changes in interest rates and monetary and other governmental policies, action and inaction. Securities of companies held by the Fund that are dependent on a single commodity, or are concentrated in a single commodity sector, may typically exhibit even higher volatility attributable to commodity prices.

Concentration Risk. To the extent that the Fund’s portfolio reflects the Underlying Index’s concentration in the securities of a particular issuer or issuers in a particular country, group of countries, region, market, industry, group of industries, sector or asset class, the Fund may be adversely affected by the performance of those securities, may be subject to increased price volatility and may be more susceptible to adverse economic, market, political or regulatory occurrences affecting that issuer, country, group of countries, region, market, industry, group of industries, sector or asset class.

Currency Risk. Because the Fund’s NAV is determined on the basis of the U.S. dollar, investors may lose money if the currency of a non-U.S. market in which the Fund invests depreciates against the U.S. dollar, even if the local currency value of the Fund’s holdings in that market increases.

Custody Risk. Custody risk refers to the risks inherent in the process of clearing and settling trades and the holding of securities by local banks, agents and depositories. Low trading volumes and volatile prices in less developed markets may make trades harder to complete and settle, and governments or trade groups may compel local agents to hold securities in designated depositories that are not subject to independent evaluation. Local agents are held only to the standards of care of their local markets. In general, the less developed a country’s securities market is, the greater the likelihood of custody problems.

Emerging Markets Risk. Investments in emerging markets are subject to a greater risk of loss than investments in more developed markets. This is due to, among other things, the potential for greater market volatility, lower trading volume, inflation, political and economic instability, greater risk of a market shutdown and more

governmental limitations on foreign investments than typically found in more developed markets. In addition, emerging markets often have less uniformity in accounting and reporting requirements, unreliable securities valuation and greater risks associated with custody of securities.

Energy Sector Risk. The energy sector is cyclical and highly dependent on commodities prices. The market values of companies in the energy sector are strongly affected by the levels and volatility of global energy prices, energy supply and demand, capital expenditures on exploration and production, energy conservation efforts, exchange rates and technological advances, among other factors. Companies in this sector may be subject to substantial government regulation and contractual fixed pricing, which may increase the cost of business and limit these companies’ earnings. A significant portion of their revenues depends on a relatively small number of customers, including governmental entities and utilities. As a result, governmental budget constraints may have a material adverse effect on the stock prices of companies in this industry. Energy companies may also operate in countries with less developed regulatory regimes or a history of expropriation, nationalization or other adverse policies. Energy companies also face a significant risk of civil liability from accidents resulting in injury or loss of life or property, pollution or other environmental mishaps, equipment malfunctions or mishandling of materials and a risk of loss from terrorism and natural disasters. Any such event could have serious consequences for the general population of the area affected and result in a material adverse impact on the Fund’s portfolio and the performance of the Fund. Energy companies can be significantly affected by the supply of, and demand for, specific products (e.g., oil and natural gas) and services, exploration and production spending, government regulation, world events and general economic conditions.

Equity Securities Risk. The Fund invests in equity securities, which are subject to changes in value that may be attributable to market perception of a particular issuer or to general stock market fluctuations that affect all issuers. Investments in equity securities may be more volatile than investments in other asset classes.

European Economic Risk. The Economic and Monetary Union of the European Union (the “EU”) requires member countries to comply with restrictions on inflation rates, deficits, interest rates, debt levels and fiscal and monetary controls, each of which may significantly affect every country in Europe. Decreasing imports or exports, changes in governmental or EU regulations on trade, changes in the exchange rate of the euro, the default or threat of default by an EU member country on its sovereign debt, and/or an economic recession in an EU member country may have a significant adverse effect on the economies of EU member countries and their trading partners, including some or all of the ACWI ex US energy sector countries. The European financial markets have recently experienced volatility and have been adversely affected by concerns about economic downturns, credit rating downgrades, rising government debt levels and possible default on or restructuring of government debt in several European countries, including Greece, Ireland, Italy, Portugal and Spain. A default or debt restructuring by any European country would adversely impact holders of that country’s debt, and sellers of credit default swaps linked to that country’s creditworthiness, which may be located in countries other than those listed in the previous sentence. These events

have adversely affected the value and exchange rate of the euro and may continue to significantly affect the economies of every country in Europe, including EU member countries that do not use the euro and non-EU member countries.

Geographic Risk. Some markets in which the Fund invests are located in parts of the world that have historically been prone to natural disasters, such as earthquakes, volcanoes, droughts, floods, hurricanes and tsunamis, and are economically sensitive to environmental events. Any natural or other disaster could have a significant adverse impact on the economies of these geographic areas, causing an adverse impact on the Fund’s investments in the affected region.

Issuer Risk. The performance of the Fund depends on the performance of individual securities to which the Fund has exposure. Any issuer of these securities may perform poorly, causing the value of its securities to decline. Poor performance may be caused by poor management decisions, competitive pressures, changes in technology, expiration of patent protection, disruptions in supply, labor problems or shortages, corporate restructurings, fraudulent disclosures or other factors. Issuers may, in times of distress or at their own discretion, decide to reduce or eliminate dividends, which may also cause their stock prices to decline.

Management Risk. The Fund may not fully replicate the Underlying Index and may hold securities not included in the Underlying Index. As a result, the Fund is subject to the risk that BFA’s investment management strategy, the implementation of which is subject to a number of constraints, may not produce the intended results.

Market Risk. The Fund could lose money due to short-term market movements and over longer periods during market downturns. Securities may decline in value due to factors affecting securities markets generally or particular industries represented in the markets. The value of a security may decline due to general market conditions, economic trends or events that are not specifically related to the issuer of the security or to factors that affect a particular industry or industries. During a general downturn in the securities markets, multiple asset classes may be negatively affected.

Market Trading Risk

Absence of Active Market. Although shares of the Fund are listed for trading on one or more stock exchanges, there can be no assurance that an active trading market for such shares will develop or be maintained.

Risk of Secondary Listings. The Fund’s shares may be listed or traded on U.S. and non-U.S. stock exchanges other than the U.S. stock exchange where the Fund’s primary listing is maintained. There can be no assurance that the Fund’s shares will continue to trade on any such stock exchange or in any market or that the Fund’s shares will continue to meet the requirements for listing or trading on any exchange or in any market. The Fund’s shares may be less actively traded in certain markets than others, and investors are subject to the execution and settlement risks and market standards of the market where they or their broker direct their trades for execution. Certain information available to investors who trade Fund shares on a U.S. stock exchange during regular U.S. market hours may not be available to investors who trade in other markets, which may result in secondary market prices in such markets being less efficient.

Secondary Market Trading Risk. Shares of the Fund may trade in the secondary market at times when the Fund does not accept orders to purchase or redeem shares. At such times, shares may trade in the secondary market with more significant premiums or discounts than might be experienced at times when the Fund accepts purchase and redemption orders.

Secondary market trading in Fund shares may be halted by a stock exchange because of market conditions or other reasons. In addition, trading in Fund shares on a stock exchange or in any market may be subject to trading halts caused by extraordinary market volatility pursuant to “circuit breaker” rules on the stock exchange or market. There can be no assurance that the requirements necessary to maintain the listing or trading of Fund shares will continue to be met or will remain unchanged.

Shares of the Fund May Trade at Prices Other Than NAV. Shares of the Fund trade on stock exchanges at prices at, above or below their most recent NAV. The NAV of the Fund is calculated at the end of each business day and fluctuates with changes in the market value of the Fund’s holdings since the most recent calculation. The trading prices of the Fund’s shares fluctuate continuously throughout trading hours based on market supply and demand rather than NAV. The trading prices of the Fund’s shares may deviate significantly from NAV during periods of market volatility. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV. However, because shares can be created and redeemed in Creation Units at NAV (unlike shares of many closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their NAVs), BFA believes that large discounts or premiums to the NAV of the Fund are not likely to be sustained over the long-term. While the creation/redemption feature is designed to make it likely that the Fund’s shares normally will trade on stock exchanges at prices close to the Fund’s next calculated NAV, exchange prices are not expected to correlate exactly with the Fund’s NAV due to timing reasons as well as market supply and demand factors. In addition, disruptions to creations and redemptions or extreme market volatility may result in trading prices for shares of the Fund that differ significantly from its NAV.

Costs of Buying or Selling Fund Shares. Buying or selling Fund shares on an exchange involves two types of costs that apply to all securities transactions. When buying or selling shares of the Fund through a broker, you will likely incur a brokerage commission or other charges imposed by brokers as determined by that broker. In addition, you may incur the cost of the “spread” – that is, the difference between what investors are willing to pay for Fund shares (the “bid” price) and the price at which they are willing to sell Fund shares (the “ask” price). Because of the costs inherent in buying or selling Fund shares, frequent trading may detract significantly from investment results and an investment in Fund shares may not be advisable for investors who anticipate regularly making small investments.

Mid-Capitalization Companies Risk. Many of the companies in which the Fund invests are considered mid-capitalization companies. Stock prices of mid-capitalization companies may be more volatile than those of large-capitalization companies and, therefore, the Fund’s share price may be more volatile than those of funds that invest a larger percentage of their assets in stocks issued by large-capitalization companies.

Stock prices of mid-capitalization companies are also more vulnerable than those of large-capitalization companies to adverse business or economic developments, and the stocks of mid-capitalization companies may be less liquid, making it difficult for the Fund to buy and sell them. In addition, mid-capitalization companies generally have less diverse product lines than large-capitalization companies and are more susceptible to adverse developments related to their products.

Non-Diversification Risk. The Fund is classified as “non-diversified.” This means that the Fund may invest a large percentage of its assets in securities issued by or representing a small number of issuers. As a result, the Fund may be more susceptible to the risks associated with these particular issuers, or to a single economic, political or regulatory occurrence affecting these issuers.

Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers are subject to all of the risks of investing in the markets where such issuers are located, including heightened risks of inflation or nationalization and market fluctuations caused by economic and political developments. As a result of investing in non-U.S. securities, the Fund may be subject to increased risk of loss caused by any of the factors listed below:

  • Lower levels of liquidity and market efficiency;
  • Greater securities price volatility;
  • Exchange rate fluctuations and exchange controls;
  • Less availability of public information about issuers;
  • Limitations on foreign ownership of securities;
  • Imposition of withholding or other taxes;
  • Imposition of restrictions on the expatriation of the funds or other assets of the Fund;
  • Higher transaction and custody costs and delays in settlement procedures;
  • Difficulties in enforcing contractual obligations;
  • Lower levels of regulation of the securities market;
  • Weaker accounting, disclosure and reporting requirements; and
  • Legal principles related to corporate governance, directors’ fiduciary duties and liabilities and stockholders’ rights in markets in which the Fund invests may differ and/or may not be as extensive or protective as those that apply in the United States.

Passive Investment Risk. The Fund is not actively managed and may be affected by a general decline in market segments related to the Underlying Index. The Fund invests in securities included in, or representative of, the Underlying Index regardless of their investment merits. BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

Privatization Risk. Some countries in which the Fund invests have begun a process of privatizing certain entities and industries. In some instances, investors in newly privatized entities have suffered losses due to the inability of the newly privatized entities to adjust quickly to a competitive environment or changing regulatory and legal

standards or, in some cases, due to re-nationalization of such privatized entities. There is no assurance that such losses will not recur.

Reliance on Trading Partners Risk. The economies of the ACWI ex US energy sector countries are dependent on each other and on the United States as key trading partners. Reduction in spending on the products and services of the ACWI ex US energy sector countries by any of their key trading partners, institution of tariffs or other trade barriers or a slowdown in the economies of any of their key trading partners may cause an adverse impact on the economies of the ACWI ex US energy sector countries.

U.S. Trading Partners Risk. The United States is a significant, and in some cases the most significant, trading partner of or foreign investor in certain ACWI ex US energy sector countries and the economies of these countries may be particularly affected by changes in the U.S. economy. Decreasing U.S. imports, new trade regulations, changes in the U.S. dollar exchange rate or a recession in the United States may have a material adverse effect on the economies of ACWI ex US energy sector countries.

Securities Lending Risk. The Fund may engage in securities lending. Securities lending involves the risk that the Fund may lose money because the borrower of the Fund’s loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for the loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Security Risk. Some geographic areas in which the Fund invests have experienced acts of terrorism or strained international relations due to territorial disputes, historical animosities or other defense concerns. These situations may cause uncertainty in the markets of these geographic areas and may adversely affect the performance of their economies.

Structural Risk. Certain political, economic, legal and currency risks have contributed to a high degree of price volatility in the equity markets of the ACWI ex US energy sector countries and could adversely affect investments in the Fund:

Political and Social Risk. Disparities of wealth, the pace and success of democratization and ethnic, religious and racial disaffection, among other factors, have led to social unrest, violence and labor unrest in some ACWI ex US energy sector countries. Unanticipated or sudden political or social developments may result in sudden and significant investment losses.

Economic Risk. Some ACWI ex US energy sector countries may experience economic instability, including instability resulting from substantial rates of inflation or significant devaluations of their currency, or economic recessions causing a negative effect on the economies and securities markets of their economies. Some of these countries may also impose restrictions on the exchange or export of currency or adverse currency exchange rates and may be characterized by a lack of available currency hedging instruments.

Expropriation and/or Nationalization Risk. Investments in certain ACWI ex US energy sector countries may be subject to loss due to expropriation or nationalization of

assets and property or the imposition of restrictions on foreign investments and repatriation of capital.

Large Government Debt Risk. Chronic structural public sector deficits in some ACWI ex US energy sector countries may adversely impact investments in the Fund.

Tracking Error Risk. Imperfect correlation between the Fund’s portfolio securities and those in the Underlying Index, rounding of prices, changes to the Underlying Index and regulatory requirements may cause tracking error, which is the divergence of the Fund’s performance from that of the Underlying Index. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Underlying Index does not. Because the Fund employs a representative sampling strategy, the Fund may experience tracking error to a greater extent than a fund that seeks to replicate an index.

Valuation Risk. Because non-U.S. exchanges may be open on days when the Fund does not price its shares, the value of the securities in the Fund’s portfolio may change on days when shareholders will not be able to purchase or sell the Fund’s shares. In addition, for purposes of calculating the Fund’s NAV, the value of assets denominated in non-U.S. currencies is converted into U.S. dollars using exchange rates deemed appropriate by BFA. This conversion may result in a difference between the prices used to calculate the Fund’s NAV and the prices used by the Underlying Index, which, in turn, could result in a difference between the Fund’s performance and the performance of the Underlying Index.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

Asian Economic Risk. Certain Asian economies have experienced over-extension of credit, currency devaluations and restrictions, high unemployment, high inflation, decreased exports and economic recessions. Economic events in any one Asian country may have a significant economic effect on the entire Asian region, as well as on major trading partners outside Asia, and any adverse event in the Asian markets may have a significant adverse effect on some or all of the ACWI ex US energy sector countries.

Central and South American Economic Risk. The economies of certain ACWI ex US energy sector countries are affected by the economies of Central and South American countries, some of which have experienced high interest rates, economic volatility, inflation, currency devaluations, government defaults and high unemployment rates. In addition, commodities (such as oil, gas and minerals) represent a significant percentage of the region’s exports and many economies in this region are particularly sensitive to fluctuations in commodity prices. Adverse economic events in one country may have a significant adverse effect on other countries in this region and on some economies of the ACWI ex US energy sector countries.

North American Economic Risk. The United States is Canada’s and Mexico’s largest trading and investment partner. The Canadian and Mexican economies are significantly

affected by developments in the U.S. economy. Since the implementation of the North American Free Trade Agreement (“NAFTA”) in 1994 among Canada, the United States and Mexico, total merchandise trade between the three countries have increased. To further this relationship, the three NAFTA countries entered into the Security and Prosperity Partnership of North America in March 2005, which may further affect Canada’s and Mexico’s dependency on the U.S. economy. Economic events in any one North American country can have a significant economic effect on the entire North American region, and on some or all of the North American countries in which the Fund invests.

Portfolio Holdings Information

A description of the Trust’s policies and procedures with respect to the disclosure of the Fund’s portfolio securities is available in the Fund’s Statement of Additional Information (“SAI”). The top holdings of the Fund can be found at www.iShares.com. Fund fact sheets provide information regarding the Fund’s top holdings and may be requested by calling 1-800-iShares (1-800-474-2737).

Management

Investment Adviser. As investment adviser, BFA has overall responsibility for the general management and administration of the Trust. BFA provides an investment program for the Fund and manages the investment of the Fund’s assets. In managing the Fund, BFA may draw upon the research and expertise of its asset management affiliates with respect to certain portfolio securities. In seeking to achieve the Fund’s investment objective, BFA uses teams of portfolio managers, investment strategists and other investment specialists. This team approach brings together many disciplines and leverages BFA’s extensive resources.

Pursuant to the Investment Advisory Agreement between BFA and the Trust (entered into on behalf of the Fund), BFA is responsible for substantially all expenses of the Fund, except interest expenses, taxes, brokerage expenses, future distribution fees or expenses and extraordinary expenses.

For its investment advisory services to the Fund, BFA is entitled to receive a management fee from the Fund based on a percentage of the Fund’s average daily net assets, at the annual rate of 0.48%.

BFA is located at 400 Howard Street, San Francisco, CA 94105. It is a wholly owned subsidiary of BTC, which in turn is indirectly wholly-owned by BlackRock, Inc. (“BlackRock”). As of September 30, 2011, BTC and its affiliates, including BFA and BlackRock, provided investment advisory services for assets in excess of $3.35 trillion. BFA, BTC, BlackRock Execution Services, BlackRock and their affiliates deal, trade and invest for their own accounts in the types of securities in which the Fund may also invest.

A discussion regarding the basis for the Trust’s Board of Trustees’ (the “Board”) approval of the Investment Advisory Agreement with BFA is available in the Fund’s annual report for the period ended July 31.

Portfolio Managers. Rene Casis, Diane Hsiung and Greg Savage are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager is responsible for various functions related to portfolio management, including, but not limited to, investing cash inflows, coordinating with members of his or her portfolio management team to focus on certain asset classes, implementing investment strategy, researching and reviewing investment strategy and overseeing members of his or her portfolio management team that have more limited responsibilities.

Rene Casis has been employed by BFA (formerly, Barclays Global Fund Advisors (“BGFA”)) and BTC (formerly, Barclays Global Investors, N.A. (“BGI”)) as a senior portfolio manager since 2009. From 2005 to 2009, Mr. Casis was a trader at Barclays Capital. Prior to that, Mr. Casis was a portfolio manager from 2000 to 2005 for BGFA and BGI. Mr. Casis has been a Portfolio Manager of the Fund since 2010.

Diane Hsiung has been employed by BFA and BTC as a senior portfolio manager since 2007. Prior to that, Ms. Hsiung was a portfolio manager from 2002 to 2006 for BGFA and BGI. Ms. Hsiung has been a Portfolio Manager of the Fund since inception.

Greg Savage has been employed by BFA and BTC as a senior portfolio manager since 2006. Prior to that, Mr. Savage was a portfolio manager from 2001 to 2006 for BGFA and BGI. Mr. Savage has been a Portfolio Manager of the Fund since inception.

The Fund’s SAI provides additional information about the Portfolio Managers’ compensation, other accounts managed by the Portfolio Managers and the Portfolio Managers’ ownership (if any) of shares in the Fund.

Administrator, Custodian and Transfer Agent. State Street Bank and Trust Company (“State Street”) is the administrator, custodian and transfer agent for the Fund.

Conflicts of Interest. BFA wants you to know that there are certain entities with which BFA has relationships that may give rise to conflicts of interest, or the appearance of conflicts of interest. These entities include the following: BFA’s affiliates (including BlackRock and The PNC Financial Services Group, Inc., and each of their affiliates, directors, partners, trustees, managing members, officers and employees (collectively, the “Affiliates”)) and BlackRock’s significant shareholder, Barclays Bank PLC and its affiliates, including Barclays PLC (each, an “Entity” and together, the “Entities”).

The activities of BFA, the Affiliates and the Entities in the management of, or their interest in, their own accounts and other accounts they manage, may present conflicts of interest that could disadvantage the Fund and the shareholders. BFA and its Affiliates or the Entities provide investment management services to other funds and discretionary managed accounts that may follow an investment program similar to that of the Fund. BFA, its Affiliates and the Entities are involved worldwide with a broad spectrum of financial services and asset management activities and may engage in the ordinary course of business in activities in which their interests or the interests of their clients may conflict with those of the Fund. BFA, one or more of the Affiliates or the Entities acts, or may act, as an investor, investment banker, research provider, investment manager, financier, underwriter, advisor, market maker, trader, prime broker, lender, agent or principal, and have other direct and indirect interests, in

securities, currencies and other instruments in which the Fund may directly or indirectly invest. Thus, it is likely that the Fund will have multiple business relationships with and will invest in, engage in transactions with, make voting decisions with respect to, or obtain services from, entities for which BFA, an Affiliate or an Entity performs or seeks to perform investment banking or other services.

BFA or one or more Affiliates or Entities may engage in proprietary trading and advise accounts and funds that have investment objectives similar to those of the Fund and/or that engage in and compete for transactions in the same types of securities, currencies and other instruments as the Fund, including in securities issued by other open-end and closed-end investment management companies, including investment companies that are affiliated with the Fund and BFA, to the extent permitted under the Investment Company Act of 1940, as amended (the “1940 Act”). The trading activities of BFA, these Affiliates and Entities are carried out without reference to positions held directly or indirectly by the Fund and may result in BFA, an Affiliate or an Entity having positions that are adverse to those of the Fund.

No Affiliate or Entity is under any obligation to share any investment opportunity, idea or strategy with the Fund. As a result, an Affiliate or an Entity may compete with the Fund for appropriate investment opportunities. As a result of this and several other factors, the results of the Fund’s investment activities may differ from those of an Affiliate or an Entity and of other accounts managed by an Affiliate or an Entity, and it is possible that the Fund could sustain losses during periods in which one or more Affiliates or Entities and other accounts achieve profits on their trading for proprietary or other accounts. The opposite result is also possible.

The Fund may, from time to time, enter into transactions in which BFA or an Affiliate’s or an Entity’s clients have an interest adverse to the Fund. Furthermore, transactions undertaken by Affiliate-advised clients may adversely impact the Fund. Transactions by one or more Affiliate- or Entity-advised clients or BFA may have the effect of diluting or otherwise disadvantaging the values, prices or investment strategies of the Fund.

An Entity may maintain securities indices as part of the product offerings. Index-based funds seek to track the performance of securities indices and may use the name of the index in the fund name. Index providers, including the Entities, may be paid licensing fees for use of their indices or index names. Entities will not be obligated to license their indices to BFA and its Affiliates, and BFA and its Affiliates will not be assured that the terms of any index licensing agreement with the Entities will be as favorable as those terms offered to other index licensees.

The Fund’s activities may be limited because of regulatory restrictions applicable to one or more Affiliates or Entities, and/or their internal policies designed to comply with such restrictions. In addition, the Fund may invest in securities of companies with which an Affiliate or an Entity has or is trying to develop investment banking relationships or in which an Affiliate or an Entity has significant debt or equity investments. The Fund also may invest in securities of companies for which an Affiliate or an Entity provides or may some day provide research coverage. An Affiliate or an Entity may have business relationships with and purchase or distribute or sell services or products from or to distributors, consultants or others who recommend the Fund or who engage in transactions with or for the Fund, and may receive compensation for

such services. The Fund may also make brokerage and other payments to Affiliates or Entities in connection with the Fund’s portfolio investment transactions.

Pursuant to a securities lending program approved by the Board, the Fund has retained an Affiliate of BFA to serve as the securities lending agent for the Fund to the extent that the Fund participates in the securities lending program. For these services, the lending agent may receive a fee from the Fund, including a fee based on the returns earned on the Fund’s investment of the cash received as collateral for any loaned securities. In addition, one or more Affiliates may be among the entities to which the Fund may lend its portfolio securities under the securities lending program.

The activities of BFA, the Affiliates or Entities may give rise to other conflicts of interest that could disadvantage the Fund and the shareholders. BFA has adopted policies and procedures designed to address these potential conflicts of interest. See the Fund’s SAI for further information.

Shareholder Information

Additional shareholder information, including how to buy and sell shares of the Fund, is available free of charge by calling toll-free: 1-800-iShares (1-800-474-2737) or visiting our website at www.iShares.com.

Buying and Selling Shares. Shares of the Fund may be acquired or redeemed directly from the Fund only in Creation Units or multiples thereof, as discussed in the Creations and Redemptions section of this Prospectus. Only an Authorized Participant (as defined in the Creations and Redemptions section) may engage in creation or redemption transactions directly with the Fund. Once created, shares of the Fund generally trade in the secondary market in amounts less than a Creation Unit.

Shares of the Fund are listed on a national securities exchange for trading during the trading day. Shares can be bought and sold throughout the trading day like shares of other publicly-traded companies. The Trust does not impose any minimum investment for shares of the Fund purchased on an exchange. The Fund’s shares trade under the trading symbol “AXEN.”

Buying or selling Fund shares on an exchange involves two types of costs that may apply to all securities transactions. When buying or selling shares of the Fund through a broker, you will likely incur a brokerage commission or other charges determined by your broker. The commission is frequently a fixed amount and may be a significant proportional cost for investors seeking to buy or sell small amounts of shares. In addition, you may incur the cost of the “spread” – that is, any difference between the bid price and the ask price. The spread varies over time for shares of the Fund based on the trading volume and market liquidity, and is generally lower if the Fund has a lot of trading volume and market liquidity, and higher if the Fund has little trading volume and market liquidity.

The Board has adopted a policy of not monitoring for frequent purchases and redemptions of Fund shares (“frequent trading”) that appear to attempt to take advantage of a potential arbitrage opportunity presented by a lag between a change in the value of the Fund’s portfolio securities after the close of the primary markets for the Fund’s portfolio securities and the reflection of that change in the Fund’s NAV

(“market timing”), because the Fund generally sells and redeems its shares directly through transactions that are in-kind and/or for cash, subject to the conditions described below under Creations and Redemptions. The Board has not adopted a policy of monitoring for other frequent trading activity because shares of the Fund are listed for trading on a national securities exchange.

The national securities exchange on which the Fund’s shares are listed is open for trading Monday through Friday and is closed on weekends and the following holidays: New Year’s Day, Martin Luther King, Jr. Day, Presidents’ Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day. The Fund’s primary listing exchange is NYSE Arca.

Section 12(d)(1) of the 1940 Act restricts investments by investment companies in the securities of other investment companies. Registered investment companies are permitted to invest in the Fund beyond the limits set forth in Section 12(d)(1), subject to certain terms and conditions set forth in SEC rules or in an SEC exemptive order issued to the Trust. In order for a registered investment company to invest in shares of the Fund beyond the limitations of Section 12(d)(1) pursuant to the exemptive relief obtained by the Trust, the registered investment company must enter into an agreement with the Trust.

Book Entry. Shares of the Fund are held in book-entry form, which means that no stock certificates are issued. The Depository Trust Company (“DTC”) or its nominee is the record owner of all outstanding shares of the Fund and is recognized as the owner of all shares for all purposes.

Investors owning shares of the Fund are beneficial owners as shown on the records of DTC or its participants. DTC serves as the securities depository for shares of the Fund. DTC participants include securities brokers and dealers, banks, trust companies, clearing corporations and other institutions that directly or indirectly maintain a custodial relationship with DTC. As a beneficial owner of shares, you are not entitled to receive physical delivery of stock certificates or to have shares registered in your name, and you are not considered a registered owner of shares. Therefore, to exercise any right as an owner of shares, you must rely upon the procedures of DTC and its participants. These procedures are the same as those that apply to any other securities that you hold in book-entry or “street name” form.

Share Prices. The trading prices of the Fund’s shares in the secondary market generally differ from the Fund’s daily NAV and are affected by market forces such as supply and demand, economic conditions and other factors. Information regarding the intraday value of shares of the Fund, also known as the “indicative optimized portfolio value” (“IOPV”), is disseminated every 15 seconds throughout the trading day by the national securities exchange on which the Fund’s shares are listed or by market data vendors or other information providers. The IOPV is based on the current market value of the securities and/or cash required to be deposited in exchange for a Creation Unit. The IOPV does not necessarily reflect the precise composition of the current portfolio of securities held by the Fund at a particular point in time or the best possible valuation of the current portfolio. Therefore, the IOPV should not be viewed as a “real-time” update of the Fund’s NAV, which is computed only once a day. The IOPV is generally determined by using both current market quotations and/or price quotations obtained

from broker-dealers that may trade in the portfolio securities held by the Fund. The quotations of certain Fund holdings may not be updated during U.S. trading hours if such holdings do not trade in the United States. The Fund is not involved in, or responsible for, the calculation or dissemination of the IOPV and makes no representation or warranty as to its accuracy.

Determination of Net Asset Value. The NAV of the Fund normally is determined once daily Monday through Friday, generally as of the regularly scheduled close of business of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m., Eastern time) on each day that the NYSE is open for trading, based on prices at the time of closing provided that (a) any Fund assets or liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers (as detailed below) and (b) U.S. fixed income assets may be valued as of the announced closing time for trading in fixed income instruments in a particular market or exchange. The NAV of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets held by the Fund, and its liabilities, are determined pursuant to valuation policies and procedures approved by the Board. The Fund’s assets and liabilities are valued primarily on the basis of market quotations.

Equity investments are valued at market value, which is generally determined using the last reported official closing price or last trading price on the exchange or market on which the security is primarily traded at the time of valuation.

The Fund invests in foreign securities. Foreign currency exchange rates are generally determined as of 4:00 p.m., London time. Foreign securities owned by the Fund may trade on weekends or other days when the Fund does not price its shares. As a result, the Fund’s NAV may change on days when Authorized Participants will not be able to purchase or redeem Fund shares.

Generally, trading in foreign securities, U.S. government securities, money market instruments and certain fixed-income securities is substantially completed each day at various times prior to the close of business on the NYSE. The values of such securities used in computing the NAV of the Fund are determined as of such times.

When market quotations are not readily available or are believed by BFA to be unreliable, the Fund’s investments are valued at fair value. Fair value determinations are made by BFA in accordance with policies and procedures approved by the Fund’s Board. BFA may conclude that a market quotation is not readily available or is unreliable if a security or other asset or liability does not have a price source due to its lack of liquidity, if a market quotation differs significantly from recent price quotations or otherwise no longer appears to reflect fair value, where the security or other asset or liability is thinly traded, or where there is a significant event subsequent to the most recent market quotation. A “significant event” is an event that, in the judgment of BFA, is likely to cause a material change to the closing market price of the asset or liability

held by the Fund. Foreign securities whose values are affected by volatility that occurs in U.S. markets on a trading day after the close of foreign securities markets may be fair valued.

Fair value represents a good faith approximation of the value of an asset or liability. The fair value of an asset or liability held by the Fund is the amount the Fund might reasonably expect to receive from the current sale of that asset or the cost to extinguish that liability in an arm’s-length transaction. Valuing the Fund’s investments using fair value pricing will result in prices that may differ from current market valuations and that may not be the price at which those investments could have been sold during the period in which the particular fair values were used. Use of fair value prices and certain current market valuations could result in a difference between the prices used to calculate the Fund’s NAV and the prices used by the Underlying Index, which, in turn, could result in a difference between the Fund’s performance and the performance of the Underlying Index.

The value of assets or liabilities denominated in non-U.S. currencies will be converted into U.S. dollars using exchange rates deemed appropriate by BFA as investment adviser. Use of a rate different from the rate used by the Index Provider may adversely affect the Fund’s ability to track the Underlying Index.

Dividends and Distributions

General Policies. Dividends from net investment income, if any, generally are declared and paid semi-annually by the Fund. Distributions of net realized securities gains, if any, generally are declared and paid once a year, but the Trust may make distributions on a more frequent basis for the Fund. The Trust reserves the right to declare special distributions if, in its reasonable discretion, such action is necessary or advisable to preserve its status as a regulated investment company (“RIC”) or to avoid imposition of income or excise taxes on undistributed income or realized gains.

Dividends and other distributions on shares of the Fund are distributed on a pro rata basis to beneficial owners of such shares. Dividend payments are made through DTC participants and indirect participants to beneficial owners then of record with proceeds received from the Fund.

Dividend Reinvestment Service. No dividend reinvestment service is provided by the Trust. Broker-dealers may make available the DTC book-entry Dividend Reinvestment Service for use by beneficial owners of the Fund for reinvestment of their dividend distributions. Beneficial owners should contact their broker to determine the availability and costs of the service and the details of participation therein. Brokers may require beneficial owners to adhere to specific procedures and timetables. If this service is available and used, dividend distributions of both income and realized gains will be automatically reinvested in additional whole shares of the Fund purchased in the secondary market.

Taxes. As with any investment, you should consider how your investment in shares of the Fund will be taxed. The tax information in this Prospectus is provided as general information, based on current law. You should consult your own tax professional about the tax consequences of an investment in shares of the Fund.

Unless your investment in Fund shares is made through a tax-exempt entity or tax-deferred retirement account, such as an IRA, you need to be aware of the possible tax consequences when the Fund makes distributions or you sell Fund shares.

Taxes on Distributions. Distributions from the Fund’s net investment income (other than qualified dividend income), including distributions of income from securities lending and distributions out of the Fund’s net short-term capital gains, if any, are taxable to you as ordinary income. Distributions by the Fund of net long-term capital gains in excess of net short-term capital losses (capital gain dividends) are taxable to you as long-term capital gains, generally at a 15% tax rate (0% at certain income levels), regardless of how long you have held the Fund’s shares. Distributions by the Fund that qualify as qualified dividend income are taxable to you at long-term capital gain rates for taxable years beginning on or before December 31, 2012. The 15% and 0% tax rates expire for taxable years beginning after December 31, 2012. Maximum long-term capital gain income tax rates are scheduled to rise to 20% in 2013. Beginning in 2013, a 3.8% U.S. federal Medicare contribution tax will be imposed on “net investment income,” including interest, dividends, and capital gains, of U.S. individuals with income exceeding $200,000 (or $250,000 if married and filing jointly), and of estates and trusts.

Dividends will be qualified dividend income to you if they are attributable to qualified dividend income received by the Fund. Generally, qualified dividend income includes dividend income from taxable U.S. corporations and qualified non-U.S. corporations, provided that the Fund satisfies certain holding period requirements in respect of the stock of such corporations and has not hedged its position in the stock in certain ways. Substitute dividends received by the Fund with respect to dividends paid on securities lent out will not be qualified dividend income. For this purpose, a qualified non-U.S. corporation means any non-U.S. corporation that is eligible for benefits under a comprehensive income tax treaty with the United States, which includes an exchange of information program or if the stock with respect to which the dividend was paid is readily tradable on an established United States securities market. The term excludes a corporation that is a passive foreign investment company.

Dividends received by the Fund from a real estate investment trust (“REIT”) or another RIC generally are qualified dividend income only to the extent the dividend distributions are made out of qualified dividend income received by such REIT or RIC. It is expected that dividends received by the Fund from a REIT and distributed to a shareholder generally will be taxable to the shareholder as ordinary income.

For a dividend to be treated as qualified dividend income, the dividend must be received with respect to a share of stock held without being hedged by the Fund, and with respect to a share of the Fund held without being hedged by you, for 61 days during the 121-day period beginning at the date which is 60 days before the date on which such share becomes ex-dividend with respect to such dividend or, in the case of certain preferred stock, 91 days during the 181-day period beginning 90 days before such date.

If your Fund shares are loaned out pursuant to a securities lending arrangement, you may lose the ability to use foreign tax credits passed through by the Fund or to treat Fund dividends paid while the shares are held by the borrower as qualified dividend income.

In general, your distributions are subject to U.S. federal income tax for the year when they are paid. Certain distributions paid in January, however, may be treated as paid on December 31 of the prior year.

If the Fund’s distributions exceed current and accumulated earnings and profits, all or a portion of the distributions made in the taxable year may be recharacterized as a return of capital to shareholders. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and result in a higher capital gain or lower capital loss when those shares on which the distribution was received are sold. Once a shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain, if the shareholder holds shares of the Fund as capital assets.

If you are neither a resident nor a citizen of the United States or if you are a non-U.S. entity, the Fund’s ordinary income dividends (which include distributions of net short-term capital gains) will generally be subject to a 30% U.S. withholding tax, unless a lower treaty rate applies, provided that withholding tax will generally not apply to any gain or income realized by a non-U.S. shareholder in respect of any distributions of long-term capital gains or upon the sale or other disposition of shares of the Fund.

A 30% withholding tax will be imposed on dividends paid after December 31, 2013, and redemption proceeds paid after December 31, 2014, to (i) foreign financial institutions including non-U.S. investment funds unless they agree to collect and disclose to the Internal Revenue Service (“IRS”) information regarding their direct and indirect U.S. account holders and (ii) certain other foreign entities, unless they certify certain information regarding their direct and indirect U.S. owners. To avoid withholding, foreign financial institutions will need to enter into agreements with the IRS that state that they will provide the IRS information, including the name, address and taxpayer identification number of direct and indirect U.S. account holders, comply with due diligence procedures with respect to the identification of U.S. accounts, report to the IRS certain information with respect to U.S. accounts maintained, agree to withhold tax on certain payments made to non-compliant foreign financial institutions or to account holders who fail to provide the required information, and determine certain other information as to their account holders. Other foreign entities will need to provide the name, address, and taxpayer identification number of each substantial U.S. owner or certifications of no substantial U.S. ownership unless certain exceptions apply.

Dividends, interest and capital gains earned by the Fund with respect to non-U.S. securities may give rise to withholding and other taxes imposed by non-U.S. countries. Tax conventions between certain countries and the United States may reduce or eliminate such taxes. If more than 50% of the total assets of the Fund at the close of a year consists of non-U.S. stocks or securities, the Fund may “pass through” to you certain non-U.S. income taxes (including withholding taxes) paid by the Fund. This means that you would be considered to have received as an additional dividend your share of such non-U.S. taxes, but you may be entitled to either a corresponding tax

deduction in calculating your taxable income, or, subject to certain limitations, a credit in calculating your U.S. federal income tax.

For purposes of foreign tax credits for U.S. shareholders of the Fund, foreign capital gains taxes may not produce associated foreign source income, thereby limiting a U.S. person’s ability to use such credits.

If you are a resident or a citizen of the United States, by law, back-up withholding will apply to your distributions and proceeds if you have not provided a taxpayer identification number or social security number and made other required certifications.

Taxes When Shares are Sold. Currently, any capital gain or loss realized upon a sale of Fund shares is generally treated as a long-term gain or loss if the shares have been held for more than one year. Any capital gain or loss realized upon a sale of Fund shares held for one year or less is generally treated as short-term gain or loss, except that any capital loss on the sale of shares held for six months or less is treated as long-term capital loss to the extent that capital gain dividends were paid with respect to such shares. Beginning in 2013, any such capital gains, including from sales of Fund shares or from capital gain dividends, will be included in “net investment income” for purposes of the 3.8% U.S. federal Medicare contribution tax mentioned above.

The foregoing discussion summarizes some of the consequences under current U.S. federal tax law of an investment in the Fund. It is not a substitute for personal tax advice. You may also be subject to state and local taxation on Fund distributions and sales of shares. Consult your personal tax adviser about the potential tax consequences of an investment in shares of the Fund under all applicable tax laws.

Creations and Redemptions. Prior to trading in the secondary market, shares of the Fund are “created” at NAV by market makers, large investors and institutions only in block-size Creation Units of 50,000 shares or multiples thereof. Each “creator” or “Authorized Participant” enters into an authorized participant agreement with the Fund’s distributor, SEI Investments Distribution Co. (the “Distributor”). Only an Authorized Participant may create or redeem Creation Units directly with the Fund. A creation transaction, which is subject to acceptance by the transfer agent, generally takes place when an Authorized Participant deposits into the Fund a designated portfolio of securities and a specified amount of cash approximating the holdings of the Fund in exchange for a specified number of Creation Units. To the extent practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund.

Similarly, shares can be redeemed only in Creation Units, generally for a designated portfolio of securities and a specified amount of cash held by the Fund (“Fund Securities”). Except when aggregated in Creation Units, shares are not redeemable by the Fund. The prices at which creations and redemptions occur are based on the next calculation of NAV after an order is received in a form described in the authorized participant agreement.

The Fund intends to comply with the U.S. federal securities laws in accepting securities for deposit and satisfying redemptions with redemption securities by, among other means, assuring that any securities accepted for deposit and any securities used to satisfy redemption requests will be sold in transactions that would be exempt from

registration under the Securities Act of 1933, as amended (the “1933 Act”). Further, an Authorized Participant that is not a “qualified institutional buyer,” as such term is defined under Rule 144A of the 1933 Act, will not be able to receive Fund Securities that are restricted securities eligible for resale under Rule 144A.

Creations and redemptions must be made through a firm that is either a member of the Continuous Net Settlement System of the National Securities Clearing Corporation or a DTC participant and has executed an agreement with the Distributor with respect to creations and redemptions of Creation Unit aggregations. Information about the procedures regarding creation and redemption of Creation Units (including the cut-off times for receipt of creation and redemption orders) is included in the Fund’s SAI.

Because new shares may be created and issued on an ongoing basis, at any point during the life of the Fund a “distribution,” as such term is used in the 1933 Act, may be occurring. Broker-dealers and other persons are cautioned that some activities on their part may, depending on the circumstances, result in their being deemed participants in a distribution in a manner that could render them statutory underwriters and subject to the prospectus delivery and liability provisions of the 1933 Act. Any determination of whether one is an underwriter must take into account all the relevant facts and circumstances of each particular case.

Broker-dealers should also note that dealers who are not “underwriters” but are participating in a distribution (as contrasted to ordinary secondary transactions), and thus dealing with shares that are part of an “unsold allotment” within the meaning of Section 4(3)(C) of the 1933 Act, would be unable to take advantage of the prospectus delivery exemption provided by Section 4(3) of the 1933 Act. For delivery of prospectuses to exchange members, the prospectus delivery mechanism of Rule 153 under the 1933 Act is available only with respect to transactions on a national securities exchange.

Costs Associated with Creations and Redemptions. Authorized Participants are charged standard creation and redemption transaction fees to offset transfer and other transaction costs associated with the issuance and redemption of Creation Units. The standard creation and redemption transaction fees are set forth in the table below. The standard creation transaction fee is charged to the Authorized Participant on the day such Authorized Participant creates a Creation Unit, and is the same regardless of the number of Creation Units purchased by the Authorized Participant on the applicable business day. Similarly, the standard redemption transaction fee is charged to the Authorized Participant on the day such Authorized Participant redeems a Creation Unit, and is the same regardless of the number of Creation Units redeemed by the Authorized Participant on the applicable business day. Creations and redemptions for cash (when cash creations and redemptions (in whole or in part) are available or specified) are also subject to an additional charge (up to the maximum amounts shown in the table below). This charge is intended to compensate for brokerage, tax, foreign exchange, execution, market impact and other costs and expenses related to cash transactions. Investors who use the services of a broker or other financial intermediary may pay fees for such services.

The following table shows, as of September 30, 2011, the approximate value of one Creation Unit, standard fees and maximum additional charges for creations and redemptions (as described above):

Householding. Householding is an option available to certain Fund investors. Householding is a method of delivery, based on the preference of the individual investor, in which a single copy of certain shareholder documents can be delivered to investors who share the same address, even if their accounts are registered under different names. Please contact your broker-dealer if you are interested in enrolling in householding and receiving a single copy of prospectuses and other shareholder documents, or if you are currently enrolled in householding and wish to change your householding status.

Distribution

The Distributor distributes Creation Units for the Fund on an agency basis. The Distributor does not maintain a secondary market in shares of the Fund. The Distributor has no role in determining the policies of the Fund or the securities that are purchased or sold by the Fund. The Distributor’s principal address is One Freedom Valley Drive, Oaks, PA 19456.

In addition, BFA or its Affiliates make payments to broker-dealers, banks or other financial intermediaries (together, “intermediaries”) related to marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems, or their making shares of the Fund and certain other iShares funds available to their customers. Such payments, which may be significant to the intermediary, are not made by the Fund. Rather, such payments are made by BFA or its Affiliates from their own resources, which come directly or indirectly in part from fees paid by the iShares funds complex. Payments of this type are sometimes referred to as revenue-sharing payments. A financial intermediary may make decisions about which investment options it recommends or makes available, or the level of services provided, to its customers based on the revenue-sharing payments it is eligible to receive. Therefore, such payments to an intermediary create conflicts of interest between the intermediary and its customers and may cause the intermediary to recommend the Fund or other iShares funds over another investment. More information regarding these payments is contained in the Fund’s SAI. Please contact your salesperson or other investment professional for more information regarding any such payments his or her firm may receive from BFA or its Affiliates.

Financial Highlights

The financial highlights table is intended to help investors understand the Fund’s financial performance since inception. Certain information reflects financial results for a single share of the Fund. The total returns in the table represent the rate that an investor would have earned (or lost) on an investment in the Fund, assuming reinvestment of all dividends and distributions. This information has been audited by PricewaterhouseCoopers LLP, whose report is included, along with the Fund’s financial statements, in the Fund’s Annual Report (available upon request).

Supplemental Information

I. Premium/Discount Information

The table that follows presents information about the differences between the daily market price on secondary markets for shares of the Fund and the Fund’s NAV. NAV is the price at which the Fund issues and redeems shares. It is calculated in accordance with the standard formula for valuing mutual fund shares. The price used to calculate market returns (“Market Price”) of the Fund generally is determined using the midpoint between the highest bid and the lowest offer on the primary securities exchange on which shares of the Fund are listed for trading, as of the time that the Fund’s NAV is calculated. The Fund’s Market Price may be at, above or below its NAV. The NAV of the Fund will fluctuate with changes in the value of its portfolio holdings. The Market Price of the Fund will fluctuate in accordance with changes in its NAV, as well as market supply and demand.

Premiums or discounts are the differences (expressed as a percentage) between the NAV and Market Price of the Fund on a given day, generally at the time the NAV is calculated. A premium is the amount that the Fund is trading above the reported NAV, expressed as a percentage of the NAV. A discount is the amount that the Fund is trading below the reported NAV, expressed as a percentage of the NAV.

The following information shows the frequency of distributions of premiums and discounts for the Fund from October 1, 2010 through September 30, 2011.

Each line in the table shows the number of trading days in which the Fund traded within the premium/discount range indicated. The number of trading days in each premium/discount range is also shown as a percentage of the total number of trading days in the period covered by the table. All data presented here represents past performance, which cannot be used to predict future results.

II. Total Return Information

The table that follows presents information about the total returns of the Fund and the Underlying Index as of the fiscal year ended July 31, 2011.

“Average Annual Total Returns” represent the average annual change in value of an investment over the periods indicated. “Cumulative Total Returns” represent the total change in value of an investment over the period indicated.

The Fund’s NAV is the value of one share of the Fund as calculated in accordance with the standard formula for valuing mutual fund shares. The NAV return is based on the NAV of the Fund and the market return is based on the Market Price of the Fund. Market Price is determined by using the midpoint between the highest bid and the lowest offer on the primary stock exchange on which shares of the Fund are listed for trading, as of the time that the Fund’s NAV is calculated. Since shares of the Fund did not trade in the secondary market until after the Fund’s inception, for the period from inception to the first day of secondary market trading in shares of the Fund, the NAV of the Fund is used as a proxy for the Market Price to calculate market returns. Market and NAV returns assume that dividends and capital gain distributions have been reinvested in the Fund at Market Price and NAV, respectively.

An index is a statistical composite that tracks a specified financial market or sector. Unlike the Fund, the Underlying Index does not actually hold a portfolio of securities and therefore does not incur the expenses incurred by the Fund. These expenses negatively impact the performance of the Fund. Also, market returns do not include brokerage commissions that may be payable on secondary market transactions. If brokerage commissions were included, market returns would be lower. The returns shown in the following table do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption or sale of Fund shares. The investment return and principal value of shares of the Fund will vary with changes in market conditions. Shares of the Fund may be worth more or less than their original cost when they are redeemed or sold in the market. The Fund’s past performance is no guarantee of future results.

Fund Overview

iSHARES® MSCI ACWI ex US FINANCIALS SECTOR INDEX FUND

Ticker: AXFN Stock Exchange: NASDAQ

Investment Objective

The iShares MSCI ACWI ex US Financials Sector Index Fund (the “Fund”) seeks investment results that correspond generally to the price and yield performance, before fees and expenses, of the MSCI All Country World ex USA Financials Index (the “Underlying Index”).

Fees and Expenses

The following table describes the fees and expenses that you will incur if you own shares of the Fund. The investment advisory agreement between iShares Trust (the “Trust”) and BlackRock Fund Advisors (“BFA”) (the “Investment Advisory Agreement”) provides that BFA will pay all operating expenses of the Fund, except interest expenses, taxes, brokerage expenses, future distribution fees or expenses, and extraordinary expenses.

You may also incur usual and customary brokerage commissions when buying or selling shares of the Fund, which are not reflected in the example that follows:

Example. This Example is intended to help you compare the cost of owning shares of the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

Portfolio Turnover. The Fund may pay transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 6% of the average value of its portfolio.

Principal Investment Strategies

The Underlying Index is a free float-adjusted market capitalization-weighted index designed to measure the combined equity market performance of the financials sector of developed and emerging market countries, excluding the United States. Component securities include those of banks, diversified financial companies, insurance companies and real estate companies. As of September 30, 2011, the Underlying Index consisted of companies in the following countries and regions: Australia, Austria, Belgium, Brazil, Canada, Chile, China, Colombia, the Czech Republic, Denmark, Egypt, Finland, France, Germany, Greece, Hong Kong, Hungary, India, Indonesia, Ireland, Israel, Italy, Japan, Malaysia, Mexico, Morocco, the Netherlands, New Zealand, Norway, Peru, the Philippines, Poland, Portugal, Russia, Singapore, South Africa, South Korea, Spain, Sweden, Switzerland, Taiwan, Thailand, Turkey, and the United Kingdom (together, the “ACWI ex US financial sector countries”). As of September 30, 2011, the Underlying Index was comprised of 418 securities.

BFA uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to “beat” the index it tracks and does not seek temporary defensive positions when markets decline or appear overvalued.

Indexing may eliminate the chance that the Fund will substantially outperform the Underlying Index but also may reduce some of the risks of active management, such as poor security selection. Indexing seeks to achieve lower costs and better after-tax performance by keeping portfolio turnover low in comparison to actively managed investment companies.

BFA uses a representative sampling indexing strategy to manage the Fund. “Representative sampling” is an indexing strategy that involves investing in a representative sample of securities that collectively has an investment profile similar to the Underlying Index. The securities selected are expected to have, in the aggregate, investment characteristics (based on factors such as market capitalization and industry weightings), fundamental characteristics (such as return variability and yield) and liquidity measures similar to those of the Underlying Index. The Fund may or may not hold all of the securities in the Underlying Index.

The Fund generally invests at least 80% of its assets in securities of the Underlying Index and in depositary receipts representing securities of the Underlying Index. The Fund may invest the remainder of its assets in securities not included in the Underlying Index,

S-2   


Table Of Contents



but which BFA believes will help the Fund track the Underlying Index and in other investments including futures contracts, options on futures contracts, options and swaps as well as cash and cash equivalents, including shares of money market funds advised by BFA or its affiliates.

The Fund may lend securities representing up to one-third of the value of the Fund’s total assets (including the value of the collateral received).

The Underlying Index is sponsored by an organization (the “Index Provider”) that is independent of the Fund and BFA. The Index Provider determines the composition and relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index. The Fund’s Index Provider is MSCI Inc. (“MSCI”).

Industry Concentration Policy. The Fund will concentrate its investments (i.e., hold 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. For purposes of this limitation, securities of the U.S. government (including its agencies and instrumentalities) and repurchase agreements collateralized by U.S. government securities are not considered to be issued by members of any industry.

Summary of Principal Risks

As with any investment, you could lose all or part of your investment in the Fund, and the Fund’s performance could trail that of other investments. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund’s net asset value per share (“NAV”), trading price, yield, total return and ability to meet its investment objective.

Asset Class Risk. Securities in the Underlying Index or in the Fund’s portfolio may underperform in comparison to the general securities markets or other asset classes.

Concentration Risk. To the extent that the Fund’s investments are concentrated in a particular issuer, region, country, market, industry or asset class, the Fund may be susceptible to loss due to adverse occurrences affecting that issuer, region, country, market, industry or asset class.

Currency Risk. Because the Fund’s NAV is determined in U.S. dollars, the Fund’s NAV could decline if the currency of a non-U.S. market in which the Fund invests depreciates against the U.S. dollar.

Custody Risk. Less developed markets are more likely to experience problems with the clearing and settling of trades and the holding of securities by local banks, agents and depositories.

Emerging Markets Risk. The Fund’s investments in emerging markets may be subject to a greater risk of loss than investments in more developed markets. Emerging markets may be more likely to experience inflation risk, political turmoil and rapid changes in economic conditions than more developed markets. Emerging markets often have less uniformity in accounting and reporting requirements, unreliable securities valuation and greater risk associated with custody of securities.

Equity Securities Risk. Equity securities are subject to changes in

S-3   


Table Of Contents



value and their values may be more volatile than other asset classes.

Financial Sector Risk. Performance of companies in the financial sector may be adversely impacted by many factors, including, among others, government regulations, economic conditions, credit rating downgrades, changes in interest rates, and decreased liquidity in credit markets. This sector has experienced significant losses in the recent past, and the impact of more stringent capital requirements and of recent or future regulation on any individual financial company or on the sector as a whole cannot be predicted.

Geographic Risk. A natural or other disaster could occur in a geographic region in which the Fund invests, which could affect the economy or particular business operations of companies in the specific geographic region, causing an adverse impact on the Fund’s investments in the affected region.

Insurance Industry Risk. The insurance industry may be significantly affected by changes in interest rates, catastrophic events, price and marketing competition, the imposition of premium rate caps, or other changes in government regulation or tax law, among other factors.

Issuer Risk. Fund performance depends on the performance of individual securities to which the Fund has exposure. Changes to the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA’s investment management strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares, losses from trading in secondary markets, periods of high volatility and disruption in the creation/redemption process of the Fund. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV.

Mid-Capitalization Companies Risk. The Fund may invest in the securities of mid-capitalization companies. Compared to large-capitalization companies, mid-capitalization companies may be less stable and more susceptible to adverse developments and their securities may be more volatile and less liquid.

Non-Diversification Risk. The Fund may invest a large percentage of its assets in securities issued by or representing a small number of issuers. As a result, the Fund’s performance may depend on the performance of a small number of issuers.

Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers are subject to the risks associated with investing in those non-U.S. markets, such as heightened risks of inflation or nationalization. The Fund may lose money due to political, economic and geographic events affecting a non-U.S. issuer or market. The Fund is specifically exposed to Asian Economic Risk and European Economic Risk.



S-4   


Table Of Contents



Passive Investment Risk. The Fund is not actively managed and BFA does not attempt to take defensive positions under any market conditions, including declining markets.

Privatization Risk. Some countries in which the Fund invests have begun a process of privatizing certain entities and industries. Privatized entities may lose money or be re-nationalized.

Reliance on Trading Partners Risk. The Fund invests in countries whose economies are heavily dependent upon trading with key partners. Any reduction in this trading may have an adverse impact on the Fund’s investments. Through its trading partners, the Fund is particularly exposed to U.S. Trading Partner Risk.

Securities Lending Risk. The Fund may engage in securities lending. Securities lending involves the risk that the Fund may lose money because the borrower of the Fund’s loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Security Risk. Some countries and regions in which the Fund invests have experienced security concerns. Incidents involving a country’s or region’s security may cause uncertainty in these markets and may adversely affect their economies and the Fund’s investments.

Small-Capitalization Companies Risk. The Fund may invest in the securities of small-capitalization companies. Compared to mid- and large-capitalization companies, small-capitalization companies may be less stable and more susceptible to adverse developments and their securities may be more volatile and less liquid.

Structural Risk. The countries in which the Fund invests may be subject to considerable degrees of economic, political and social instability.

Tracking Error Risk. The performance of the Fund may diverge from that of the Underlying Index. Because the Fund employs a representative sampling strategy, the Fund may experience tracking error to a greater extent than a fund that seeks to replicate an index.

Valuation Risk. The value of the securities in the Fund’s portfolio may change on days when shareholders will not be able to purchase or sell the Fund’s shares.

Performance Information

As of the date of the Fund’s prospectus (the “Prospectus”), the Fund has been in operation for less than one full calendar year and therefore does not report its performance information.

Management

Investment Adviser. BlackRock Fund Advisors.

Portfolio Managers. Rene Casis, Diane Hsiung and Greg Savage (the “Portfolio Managers”) are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager supervises a portfolio management team. Mr. Casis has been a Portfolio Manager of the Fund since 2010. Ms. Hsiung and Mr. Savage have been Portfolio Managers of the Fund since inception.

Purchase and Sale of Fund Shares

The Fund is an exchange-traded fund (commonly referred to as an “ETF”). Individual Fund shares may only be purchased and sold on a national securities exchange through a broker-dealer. The price of Fund shares is based on market price, and because ETF shares trade at market prices rather than NAV, shares may trade at a price greater than NAV (a premium) or less than NAV (a discount). The Fund will only issue or redeem shares that have been aggregated into blocks of 50,000 shares or multiples thereof (“Creation Units”) to authorized participants who have entered into agreements with the Fund’s distributor. The Fund generally will issue or redeem Creation Units in return for a designated portfolio of securities (and an amount of cash) that the Fund specifies each day.

Tax Information

The Fund intends to make distributions that may be taxable to you as ordinary income or capital gains, unless you are investing through a tax-deferred arrangement such as a 401(k) plan or an individual retirement account (“IRA”).

Payments to Broker-Dealers and other Financial Intermediaries

If you purchase shares of the Fund through a broker-dealer or other financial intermediary (such as a bank), BFA or other related companies may pay the intermediary for marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems or other services related to the sale or promotion of the Fund. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.

More Information About the Fund

This Prospectus contains important information about investing in the Fund. Please read this Prospectus carefully before you make any investment decisions. Additional information regarding the Fund is available at www.iShares.com.

BFA is the investment adviser to the Fund. Shares of the Fund are listed for trading on The NASDAQ Stock Market (“NASDAQ”). The market price for a share of the Fund may be different from the Fund’s most recent NAV.

ETFs are funds that trade like other publicly-traded securities. The Fund is designed to track an index. Similar to shares of an index mutual fund, each share of the Fund represents a partial ownership in an underlying portfolio of securities intended to track a market index. Unlike shares of a mutual fund, which can be bought and redeemed from the issuing fund by all shareholders at a price based on NAV, shares of the Fund may be purchased or redeemed directly from the Fund at NAV solely by authorized participants. Also unlike shares of a mutual fund, shares of the Fund are listed on a national securities exchange and trade in the secondary market at market prices that change throughout the day.

The Fund invests in a particular segment of the securities markets and seeks to track the performance of a securities index that generally is not representative of the market as a whole. The Fund is designed to be used as part of broader asset allocation strategies. Accordingly, an investment in the Fund should not constitute a complete investment program.

An index is a theoretical financial calculation while the Fund is an actual investment portfolio. The performance of the Fund and the Underlying Index may vary due to transaction costs, non-U.S. currency valuations, asset valuations, corporate actions (such as mergers and spin-offs), timing variances and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions (such as diversification requirements) that apply to the Fund but not to the Underlying Index or to the use of representative sampling. “Tracking error” is the difference between the performance (return) of the Fund’s portfolio and that of the Underlying Index. BFA expects that, over time, the Fund’s tracking error will not exceed 5%. Because the Fund uses a representative sampling indexing strategy, it can be expected to have a larger tracking error than if it used a replication indexing strategy. “Replication” is an indexing strategy in which a fund invests in substantially all of the securities in its underlying index in approximately the same proportions as in the underlying index.

An investment in the Fund is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, BFA or any of its affiliates.

The Fund’s investment objective and the Underlying Index may be changed without shareholder approval.

A Further Discussion of Principal Risks

The Fund is subject to various risks, including the principal risks noted below, any of which may adversely affect the Fund’s NAV, trading price, yield, total return and ability to meet its investment objective. You could lose all or part of your investment in the Fund, and the Fund could underperform other investments.

Asian Economic Risk. Certain Asian economies have experienced over-extension of credit, currency devaluations and restrictions, high unemployment, high inflation, decreased exports and economic recessions. Economic events in any one Asian country may have a significant economic effect on the entire Asian region, as well as on major trading partners outside Asia, and any adverse event in the Asian markets may have a significant adverse effect on some or all of the ACWI ex US financial sector countries.

Asset Class Risk. The securities in the Underlying Index or in the Fund’s portfolio may underperform the returns of other securities or indexes that track other countries, groups of countries, regions, industries, groups of industries, markets, asset classes or sectors. Various types of securities or indexes tend to experience cycles of outperformance and underperformance in comparison to the general securities markets.

Concentration Risk. To the extent that the Fund’s portfolio reflects the Underlying Index’s concentration in the securities of a particular issuer or issuers in a particular country, group of countries, region, market, industry, group of industries, sector or asset class, the Fund may be adversely affected by the performance of those securities, may be subject to increased price volatility and may be more susceptible to adverse economic, market, political or regulatory occurrences affecting that issuer, country, group of countries, region, market, industry, group of industries, sector or asset class.

Currency Risk. Because the Fund’s NAV is determined on the basis of the U.S. dollar, investors may lose money if the currency of a non-U.S. market in which the Fund invests depreciates against the U.S. dollar, even if the local currency value of the Fund’s holdings in that market increases.

Custody Risk. Custody risk refers to the risks inherent in the process of clearing and settling trades and the holding of securities by local banks, agents and depositories. Low trading volumes and volatile prices in less developed markets may make trades harder to complete and settle, and governments or trade groups may compel local agents to hold securities in designated depositories that are not subject to independent evaluation. Local agents are held only to the standards of care of their local markets. In general, the less developed a country’s securities market is, the greater the likelihood of custody problems.

Emerging Markets Risk. Investments in emerging markets are subject to a greater risk of loss than investments in more developed markets. This is due to, among other things, the potential for greater market volatility, lower trading volume, inflation, political and economic instability, greater risk of a market shutdown and more governmental limitations on foreign investments than typically found in more developed markets. In addition, emerging markets often have less uniformity in

accounting and reporting requirements, unreliable securities valuation and greater risks associated with custody of securities.

Equity Securities Risk. The Fund invests in equity securities, which are subject to changes in value that may be attributable to market perception of a particular issuer or to general stock market fluctuations that affect all issuers. Investments in equity securities may be more volatile than investments in other asset classes.

European Economic Risk. The Economic and Monetary Union of the European Union (the “EU”) requires member countries to comply with restrictions on inflation rates, deficits, interest rates, debt levels and fiscal and monetary controls, each of which may significantly affect every country in Europe. Decreasing imports or exports, changes in governmental or EU regulations on trade, changes in the exchange rate of the euro, the default or threat of default by an EU member country on its sovereign debt, and/or an economic recession in an EU member country may have a significant adverse effect on the economies of EU member countries and their trading partners, including some or all of the countries in which the Fund invests. The European financial markets have recently experienced volatility and have been adversely affected by concerns about economic downturns, credit rating downgrades, rising government debt levels and possible default on or restructuring of government debt in several European countries, including Greece, Ireland, Italy, Portugal and Spain. A default or debt restructuring by any European country would adversely impact holders of that country’s debt, and sellers of credit default swaps linked to that country’s creditworthiness, which may be located in countries other than those listed in the previous sentence. These events have adversely affected the value and exchange rate of the euro and may continue to significantly affect the economies of every country in Europe, including EU member countries that do not use the euro and non-EU member countries.

Financial Sector Risk. Companies in the financial sector of an economy are often subject to governmental regulation and, recently, government intervention and the potential for additional regulation, which may adversely affect the scope of their activities, the prices they can charge and the amount of capital they must maintain. Governmental regulation may change frequently and may have significant adverse consequences for companies in the financial sector, including effects not intended by such regulation. The impact of recent or future regulation in various countries on any individual financial company or on the sector as a whole cannot be predicted. Certain risks may impact the value of investments in the financial sector more severely than investments outside this sector, including the risks associated with companies that operate with substantial financial leverage. Companies in the financial sector may also be adversely affected by increases in interest rates and loan losses, decreases in the availability of money or asset valuations, credit rating downgrades and adverse conditions in other related markets. Over the past few years, the deterioration of the credit markets has impacted a broad range of mortgage, asset-backed, auction rate, sovereign debt and other markets, including non-U.S. credit and interbank money markets, thereby affecting a wide range of financial institutions and markets. This situation has created instability in the financial markets and caused certain financial companies to incur large losses. Some financial companies have experienced declines in the valuations of their assets, taken actions to raise capital (such as the issuance of

debt or equity securities), or even ceased operations. Some financial companies have borrowed significant amounts of capital from governments and may face future government-imposed restrictions on their businesses or increased government intervention. These actions have caused the securities of many financial companies to decline in value. Insurance companies, in particular, may be subject to severe price competition, which may have an adverse impact on their profitability.

Geographic Risk. Some markets in which the Fund invests are located in parts of the world that have historically been prone to natural disasters, such as earthquakes, volcanoes, droughts, floods, hurricanes and tsunamis, and are economically sensitive to environmental events. Any natural or other disaster could have a significant adverse impact on the economies of these geographic areas, causing an adverse impact on the Fund’s investments in the affected region.

Insurance Industry Risk. The insurance industry is subject to extensive government regulation in some countries and can be significantly affected by changes in interest rates, general economic conditions, price and marketing competition, the imposition of premium rate caps, or other changes in government regulation or tax law. Different segments of the insurance industry can be significantly affected by mortality and morbidity rates, environmental clean-up costs and catastrophic events such as earthquakes, hurricanes and terrorist acts.

Issuer Risk. The performance of the Fund depends on the performance of individual securities to which the Fund has exposure. Any issuer of these securities may perform poorly, causing the value of its securities to decline. Poor performance may be caused by poor management decisions, competitive pressures, changes in technology, expiration of patent protection, disruptions in supply, labor problems or shortages, corporate restructurings, fraudulent disclosures or other factors. Issuers may, in times of distress or at their own discretion, decide to reduce or eliminate dividends, which may also cause their stock prices to decline.

Management Risk. The Fund may not fully replicate the Underlying Index and may hold securities not included in the Underlying Index. As a result, the Fund is subject to the risk that BFA’s investment management strategy, the implementation of which is subject to a number of constraints, may not produce the intended results.

Market Risk. The Fund could lose money due to short-term market movements and over longer periods during market downturns. Securities may decline in value due to factors affecting securities markets generally or particular industries represented in the markets. The value of a security may decline due to general market conditions, economic trends or events that are not specifically related to the issuer of the security or to factors that affect a particular industry or industries. During a general downturn in the securities markets, multiple asset classes may be negatively affected.

Market Trading Risk

Absence of Active Market. Although shares of the Fund are listed for trading on one or more stock exchanges, there can be no assurance that an active trading market for such shares will develop or be maintained.

Risk of Secondary Listings. The Fund’s shares may be listed or traded on U.S. and non-U.S. stock exchanges other than the U.S. stock exchange where the Fund’s primary

listing is maintained. There can be no assurance that the Fund’s shares will continue to trade on any such stock exchange or in any market or that the Fund’s shares will continue to meet the requirements for listing or trading on any exchange or in any market. The Fund’s shares may be less actively traded in certain markets than others, and investors are subject to the execution and settlement risks and market standards of the market where they or their broker direct their trades for execution. Certain information available to investors who trade Fund shares on a U.S. stock exchange during regular U.S. market hours may not be available to investors who trade in other markets, which may result in secondary market prices in such markets being less efficient.

Secondary Market Trading Risk. Shares of the Fund may trade in the secondary market at times when the Fund does not accept orders to purchase or redeem shares. At such times, shares may trade in the secondary market with more significant premiums or discounts than might be experienced at times when the Fund accepts purchase and redemption orders.

Secondary market trading in Fund shares may be halted by a stock exchange because of market conditions or other reasons. In addition, trading in Fund shares on a stock exchange or in any market may be subject to trading halts caused by extraordinary market volatility pursuant to “circuit breaker” rules on the stock exchange or market. There can be no assurance that the requirements necessary to maintain the listing or trading of Fund shares will continue to be met or will remain unchanged.

Shares of the Fund May Trade at Prices Other Than NAV. Shares of the Fund trade on stock exchanges at prices at, above or below their most recent NAV. The NAV of the Fund is calculated at the end of each business day and fluctuates with changes in the market value of the Fund’s holdings since the most recent calculation. The trading prices of the Fund’s shares fluctuate continuously throughout trading hours based on market supply and demand rather than NAV. The trading prices of the Fund’s shares may deviate significantly from NAV during periods of market volatility. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV. However, because shares can be created and redeemed in Creation Units at NAV (unlike shares of many closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their NAVs), BFA believes that large discounts or premiums to the NAV of the Fund are not likely to be sustained over the long-term. While the creation/redemption feature is designed to make it likely that the Fund’s shares normally will trade on stock exchanges at prices close to the Fund’s next calculated NAV, exchange prices are not expected to correlate exactly with the Fund’s NAV due to timing reasons as well as market supply and demand factors. In addition, disruptions to creations and redemptions or extreme market volatility may result in trading prices for shares of the Fund that differ significantly from its NAV.

Costs of Buying or Selling Fund Shares. Buying or selling Fund shares on an exchange involves two types of costs that apply to all securities transactions. When buying or selling shares of the Fund through a broker, you will likely incur a brokerage commission or other charges imposed by brokers as determined by that broker. In addition, you may incur the cost of the “spread” – that is, the difference between what

investors are willing to pay for Fund shares (the “bid” price) and the price at which they are willing to sell Fund shares (the “ask” price). Because of the costs inherent in buying or selling Fund shares, frequent trading may detract significantly from investment results and an investment in Fund shares may not be advisable for investors who anticipate regularly making small investments.

Mid-Capitalization Companies Risk. Many of the companies in which the Fund invests are considered mid-capitalization companies. Stock prices of mid-capitalization companies may be more volatile than those of large-capitalization companies and, therefore, the Fund’s share price may be more volatile than those of funds that invest a larger percentage of their assets in stocks issued by large-capitalization companies. Stock prices of mid-capitalization companies are also more vulnerable than those of large-capitalization companies to adverse business or economic developments, and the stocks of mid-capitalization companies may be less liquid, making it difficult for the Fund to buy and sell them. In addition, mid-capitalization companies generally have less diverse product lines than large-capitalization companies and are more susceptible to adverse developments related to their products.

Non-Diversification Risk. The Fund is classified as “non-diversified.” This means that the Fund may invest a large percentage of its assets in securities issued by or representing a small number of issuers. As a result, the Fund may be more susceptible to the risks associated with these particular issuers, or to a single economic, political or regulatory occurrence affecting these issuers.

Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers are subject to all of the risks of investing in the markets where such issuers are located, including heightened risks of inflation or nationalization and market fluctuations caused by economic and political developments. As a result of investing in non-U.S. securities, the Fund may be subject to increased risk of loss caused by any of the factors listed below:

  • Lower levels of liquidity and market efficiency;
  • Greater securities price volatility;
  • Exchange rate fluctuations and exchange controls;
  • Less availability of public information about issuers;
  • Limitations on foreign ownership of securities;
  • Imposition of withholding or other taxes;
  • Imposition of restrictions on the expatriation of the funds or other assets of the Fund;
  • Higher transaction and custody costs and delays in settlement procedures;
  • Difficulties in enforcing contractual obligations;
  • Lower levels of regulation of the securities market;
  • Weaker accounting, disclosure and reporting requirements; and
  • Legal principles related to corporate governance, directors’ fiduciary duties and
  • liabilities and stockholders’ rights in markets in which the Fund invests may differ and/or may not be as extensive or protective as those that apply in the United States.

Passive Investment Risk. The Fund is not actively managed and may be affected by a general decline in market segments related to the Underlying Index. The Fund invests in securities included in, or representative of, the Underlying Index regardless of their investment merits. BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

Privatization Risk. Some countries in which the Fund invests have begun a process of privatizing certain entities and industries. In some instances, investors in newly privatized entities have suffered losses due to the inability of the newly privatized entities to adjust quickly to a competitive environment or changing regulatory and legal standards or, in some cases, due to re-nationalization of such privatized entities. There is no assurance that such losses will not recur.

Reliance on Trading Partners Risk. The economies of the countries in which the Fund invests are dependent on each other and on the United States as key trading partners. Reduction in spending on the products and services of these countries by any of their key trading partners, institution of tariffs or other trade barriers or a slowdown in the economies of any of their key trading partners may cause an adverse impact on the economies of these countries.


U.S. Trading Partners Risk. The United States is a significant, and in some cases the most significant, trading partner of or foreign investor in certain countries and the economies of these countries may be particularly affected by changes in the U.S. economy. Decreasing U.S. imports, new trade regulations, changes in the U.S. dollar exchange rate or a recession in the United States may have a material adverse effect on the economies of the countries in which the Fund invests.

Securities Lending Risk. The Fund may engage in securities lending. Securities lending involves the risk that the Fund may lose money because the borrower of the Fund’s loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for the loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Security Risk. Some geographic areas in which the Fund invests have experienced acts of terrorism or strained international relations due to territorial disputes, historical animosities or other defense concerns. These situations may cause uncertainty in the markets of these geographic areas and may adversely affect the performance of their economies.

Small-Capitalization Companies Risk. Many of the companies in which the Fund invests are considered small-capitalization companies. Stock prices of small-capitalization companies may be more volatile than those of larger companies and, therefore, the Fund’s share price may be more volatile than those of funds that invest a larger percentage of their assets in stocks issued by mid- or large-capitalization companies. Stock prices of small-capitalization companies are generally more

vulnerable than those of mid- or large-capitalization companies to adverse business and economic developments. Securities of small-capitalization companies may be thinly traded, making it difficult for the Fund to buy and sell them. In addition, small-capitalization companies are typically less financially stable than larger, more established companies and may depend on a small number of essential personnel, making them more vulnerable to loss of personnel. Small-capitalization companies also normally have less diverse product lines than mid- or large-capitalization companies and are more susceptible to adverse developments concerning their products.

Structural Risk. Certain political, economic, legal and currency risks have contributed to a high degree of price volatility in the equity markets of the countries in which the Fund invests and could adversely affect investments in the Fund:

Political and Social Risk. Disparities of wealth, the pace and success of democratization and ethnic, religious and racial disaffection, among other factors, have led to social unrest, violence and labor unrest in some countries in which the Fund invests. Unanticipated or sudden political or social developments may result in sudden and significant investment losses.

Economic Risk. Some countries in which the Fund invests may experience economic instability, including instability resulting from substantial rates of inflation or significant devaluations of their currency, or economic recessions causing a negative effect on the economies and securities markets of their economies. Some of these countries may also impose restrictions on the exchange or export of currency or adverse currency exchange rates and may be characterized by a lack of available currency hedging instruments.

Expropriation and/or Nationalization Risk. Investments in certain countries in which the Fund invests may be subject to loss due to expropriation or nationalization of assets and property or the imposition of restrictions on foreign investments and repatriation of capital.

Large Government Debt Risk. Chronic structural public sector deficits in some countries in which the Fund invests may adversely impact investments in the Fund.

Tracking Error Risk. Imperfect correlation between the Fund’s portfolio securities and those in the Underlying Index, rounding of prices, changes to the Underlying Index and regulatory requirements may cause tracking error, which is the divergence of the Fund’s performance from that of the Underlying Index. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Underlying Index does not. Because the Fund employs a representative sampling strategy, the Fund may experience tracking error to a greater extent than a fund that seeks to replicate an index.

Valuation Risk. Because non-U.S. exchanges may be open on days when the Fund does not price its shares, the value of the securities in the Fund’s portfolio may change on days when shareholders will not be able to purchase or sell the Fund’s shares. In addition, for purposes of calculating the Fund’s NAV, the value of assets denominated in non-U.S. currencies is converted into U.S. dollars using exchange rates deemed appropriate by BFA. This conversion may result in a difference between the prices used

to calculate the Fund’s NAV and the prices used by the Underlying Index, which, in turn, could result in a difference between the Fund’s performance and the performance of the Underlying Index.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

Australasian Economic Risk. The economies of Australasia, which include Australia and New Zealand, are dependent on exports from the agricultural and mining sectors. This makes Australasian economies susceptible to fluctuations in the commodity markets. Australasian economies are also increasingly dependent on their growing service industries. Because the economies of Australasia are dependent on the economies of Asia, Europe and the United States as key trading partners and investors, reduction in spending by any of these trading partners on Australasian products and services, or negative changes in any of these economies, may cause an adverse impact on some or all of the Australasian economies.

North American Economic Risk. The United States is Canada’s and Mexico’s largest trading and investment partner. The Canadian and Mexican economies are significantly affected by developments in the U.S. economy. Since the implementation of the North American Free Trade Agreement (“NAFTA”) in 1994 among Canada, the United States and Mexico, total merchandise trade between the three countries have increased. To further this relationship, the three NAFTA countries entered into the Security and Prosperity Partnership of North America in March 2005, which may further affect Canada’s and Mexico’s dependency on the U.S. economy. Economic events in any one North American country can have a significant economic effect on the entire North American region, and on some or all of the North American countries in which the Fund invests.

Real Estate Investment Risk. The Fund invests in companies that invest in, develop, or operate real estate, or provide real estate related services (“Real Estate Companies”), such as REITs, real estate holding companies, or real estate management or development companies. Investment in Real Estate Companies exposes investors in the Fund to the risks of owning real estate directly as well as to risks that relate specifically to the way in which Real Estate Companies are organized and operated. Real estate is highly sensitive to general and local economic conditions and developments, and is characterized by intense competition and periodic overbuilding.

Portfolio Holdings Information

A description of the Trust’s policies and procedures with respect to the disclosure of the Fund’s portfolio securities is available in the Fund’s Statement of Additional Information (“SAI”). The top holdings of the Fund can be found at www.iShares.com. Fund fact sheets provide information regarding the Fund’s top holdings and may be requested by calling 1-800-iShares (1-800-474-2737).

Management

Investment Adviser. As investment adviser, BFA has overall responsibility for the general management and administration of the Trust. BFA provides an investment program for the Fund and manages the investment of the Fund’s assets. In managing the Fund, BFA may draw upon the research and expertise of its asset management affiliates with respect to certain portfolio securities. In seeking to achieve the Fund’s investment objective, BFA uses teams of portfolio managers, investment strategists and other investment specialists. This team approach brings together many disciplines and leverages BFA’s extensive resources.

Pursuant to the Investment Advisory Agreement between BFA and the Trust (entered into on behalf of the Fund), BFA is responsible for substantially all expenses of the Fund, except interest expenses, taxes, brokerage expenses, future distribution fees or expenses and extraordinary expenses.

For its investment advisory services to the Fund, BFA is entitled to receive a management fee from the Fund based on a percentage of the Fund’s average daily net assets, at the annual rate of 0.48%.

BFA is located at 400 Howard Street, San Francisco, CA 94105. It is a wholly owned subsidiary of BTC, which in turn is indirectly wholly-owned by BlackRock, Inc. (“BlackRock”). As of September 30, 2011, BTC and its affiliates, including BFA and BlackRock, provided investment advisory services for assets in excess of $3.35 trillion. BFA, BTC, BlackRock Execution Services, BlackRock and their affiliates deal, trade and invest for their own accounts in the types of securities in which the Fund may also invest.

A discussion regarding the basis for the Trust’s Board of Trustees’ (the “Board”) approval of the Investment Advisory Agreement with BFA is available in the Fund’s annual report for the period ended July 31.

Portfolio Managers. Rene Casis, Diane Hsiung and Greg Savage are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager is responsible for various functions related to portfolio management, including, but not limited to, investing cash inflows, coordinating with members of his or her portfolio management team to focus on certain asset classes, implementing investment strategy, researching and reviewing investment strategy and overseeing members of his or her portfolio management team that have more limited responsibilities.

Rene Casis has been employed by BFA (formerly, Barclays Global Fund Advisors (“BGFA”)) and BTC (formerly, Barclays Global Investors, N.A. (“BGI”)) as a senior portfolio manager since 2009. From 2005 to 2009, Mr. Casis was a trader at Barclays Capital. Prior to that, Mr. Casis was a portfolio manager from 2000 to 2005 for BGFA and BGI. Mr. Casis has been a Portfolio Manager of the Fund since 2010.

Diane Hsiung has been employed by BFA and BTC as a senior portfolio manager since 2007. Prior to that, Ms. Hsiung was a portfolio manager from 2002 to 2006 for BGFA and BGI. Ms. Hsiung has been a Portfolio Manager of the Fund since inception.

Greg Savage has been employed by BFA and BTC as a senior portfolio manager since 2006. Prior to that, Mr. Savage was a portfolio manager from 2001 to 2006 for BGFA and BGI. Mr. Savage has been a Portfolio Manager of the Fund since inception.

The Fund’s SAI provides additional information about the Portfolio Managers’ compensation, other accounts managed by the Portfolio Managers and the Portfolio Managers’ ownership (if any) of shares in the Fund.

Administrator, Custodian and Transfer Agent. State Street Bank and Trust Company (“State Street”) is the administrator, custodian and transfer agent for the Fund.

Conflicts of Interest. BFA wants you to know that there are certain entities with which BFA has relationships that may give rise to conflicts of interest, or the appearance of conflicts of interest. These entities include the following: BFA’s affiliates (including BlackRock and The PNC Financial Services Group, Inc., and each of their affiliates, directors, partners, trustees, managing members, officers and employees (collectively, the “Affiliates”)) and BlackRock’s significant shareholder, Barclays Bank PLC and its affiliates, including Barclays PLC (each, an “Entity” and together, the “Entities”).

The activities of BFA, the Affiliates and the Entities in the management of, or their interest in, their own accounts and other accounts they manage, may present conflicts of interest that could disadvantage the Fund and its shareholders. BFA and its Affiliates or the Entities provide investment management services to other funds and discretionary managed accounts that may follow an investment program similar to that of the Fund. BFA, its Affiliates and the Entities are involved worldwide with a broad spectrum of financial services and asset management activities and may engage in the ordinary course of business in activities in which their interests or the interests of their clients may conflict with those of the Fund. BFA, one or more of the Affiliates or the Entities acts, or may act, as an investor, investment banker, research provider, investment manager, financier, underwriter, advisor, market maker, trader, prime broker, lender, agent or principal, and have other direct and indirect interests, in securities, currencies and other instruments in which the Fund may directly or indirectly invest. Thus, it is likely that the Fund will have multiple business relationships with and will invest in, engage in transactions with, make voting decisions with respect to, or obtain services from, entities for which BFA, an Affiliate or an Entity performs or seeks to perform investment banking or other services.

BFA or one or more Affiliates or Entities may engage in proprietary trading and advise accounts and funds that have investment objectives similar to those of the Fund and/or that engage in and compete for transactions in the same types of securities, currencies and other instruments as the Fund, including in securities issued by other open-end and closed-end investment management companies, including investment companies that are affiliated with the Fund and BFA, to the extent permitted under the Investment Company Act of 1940, as amended (the “1940 Act”). The trading activities of BFA, these Affiliates and Entities are carried out without reference to positions held directly or indirectly by the Fund and may result in BFA, an Affiliate or an Entity having positions that are adverse to those of the Fund.

No Affiliate or Entity is under any obligation to share any investment opportunity, idea or strategy with the Fund. As a result, an Affiliate or an Entity may compete with the Fund for appropriate investment opportunities. As a result of this and several other factors, the results of the Fund’s investment activities may differ from those of an Affiliate or an Entity and of other accounts managed by an Affiliate or an Entity, and it is possible that the Fund could sustain losses during periods in which one or more Affiliates or Entities and other accounts achieve profits on their trading for proprietary or other accounts. The opposite result is also possible.

The Fund may, from time to time, enter into transactions in which BFA or an Affiliate’s or an Entity’s clients have an interest adverse to the Fund. Furthermore, transactions undertaken by Affiliate-advised clients may adversely impact the Fund. Transactions by one or more Affiliate- or Entity-advised clients or BFA may have the effect of diluting or otherwise disadvantaging the values, prices or investment strategies of the Fund.

An Entity may maintain securities indices as part of its product offerings. Index-based funds seek to track the performance of securities indices and may use the name of the index in the fund name. Index providers, including the Entities, may be paid licensing fees for use of their indices or index names. Entities will not be obligated to license their indices to BFA and its Affiliates, and BFA and its Affiliates will not be assured that the terms of any index licensing agreement with the Entities will be as favorable as those terms offered to other index licensees.

The Fund’s activities may be limited because of regulatory restrictions applicable to one or more Affiliates or Entities, and/or their internal policies designed to comply with such restrictions. In addition, the Fund may invest in securities of companies with which an Affiliate or an Entity has or is trying to develop investment banking relationships or in which an Affiliate or an Entity has significant debt or equity investments. The Fund also may invest in securities of companies for which an Affiliate or an Entity provides or may some day provide research coverage. An Affiliate or an Entity may have business relationships with and purchase or distribute or sell services or products from or to distributors, consultants or others who recommend the Fund or who engage in transactions with or for the Fund, and may receive compensation for such services. The Fund may also make brokerage and other payments to Affiliates or Entities in connection with the Fund’s portfolio investment transactions.

Pursuant to a securities lending program approved by the Board, the Fund has retained an Affiliate of BFA to serve as the securities lending agent for the Fund to the extent that the Fund participates in the securities lending program. For these services, the lending agent may receive a fee from the Fund, including a fee based on the returns earned on the Fund’s investment of the cash received as collateral for any loaned securities. In addition, one or more Affiliates may be among the entities to which the Fund may lend its portfolio securities under the securities lending program.

The activities of BFA, the Affiliates or Entities may give rise to other conflicts of interest that could disadvantage the Fund and its shareholders. BFA has adopted policies and procedures designed to address these potential conflicts of interest. See the Fund’s SAI for further information.

Shareholder Information

Additional shareholder information, including how to buy and sell shares of the Fund, is available free of charge by calling toll-free: 1-800-iShares (1-800-474-2737) or visiting our website at www.iShares.com.

Buying and Selling Shares. Shares of the Fund may be acquired or redeemed directly from the Fund only in Creation Units or multiples thereof, as discussed in the Creations and Redemptions section of this Prospectus. Only an Authorized Participant (as defined in the Creations and Redemptions section) may engage in creation or redemption transactions directly with the Fund. Once created, shares of the Fund generally trade in the secondary market in amounts less than a Creation Unit.

Shares of the Fund are listed on a national securities exchange for trading during the trading day. Shares can be bought and sold throughout the trading day like shares of other publicly-traded companies. The Trust does not impose any minimum investment for shares of the Fund purchased on an exchange. The Fund’s shares trade under the trading symbol “AXFN.”

Buying or selling Fund shares on an exchange involves two types of costs that may apply to all securities transactions. When buying or selling shares of the Fund through a broker, you will likely incur a brokerage commission or other charges determined by your broker. The commission is frequently a fixed amount and may be a significant proportional cost for investors seeking to buy or sell small amounts of shares. In addition, you may incur the cost of the “spread” – that is, any difference between the bid price and the ask price. The spread varies over time for shares of the Fund based on its trading volume and market liquidity, and is generally lower if the Fund has a lot of trading volume and market liquidity, and higher if the Fund has little trading volume and market liquidity.

The Board has adopted a policy of not monitoring for frequent purchases and redemptions of Fund shares (“frequent trading”) that appear to attempt to take advantage of a potential arbitrage opportunity presented by a lag between a change in the value of the Fund’s portfolio securities after the close of the primary markets for the Fund’s portfolio securities and the reflection of that change in the Fund’s NAV (“market timing”), because the Fund generally sells and redeems its shares directly through transactions that are in-kind and/or for cash, subject to the conditions described below under Creations and Redemptions. The Board has not adopted a policy of monitoring for other frequent trading activity because shares of the Fund are listed for trading on a national securities exchange.

The national securities exchange on which the Fund’s shares are listed is open for trading Monday through Friday and is closed on weekends and the following holidays: New Year’s Day, Martin Luther King, Jr. Day, Presidents’ Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day. The Fund’s primary listing exchange is NASDAQ.

Section 12(d)(1) of the 1940 Act restricts investments by investment companies in the securities of other investment companies. Registered investment companies are permitted to invest in the Fund beyond the limits set forth in Section 12(d)(1), subject to certain terms and conditions set forth in SEC rules or in an SEC exemptive order

issued to the Trust. In order for a registered investment company to invest in shares of the Fund beyond the limitations of Section 12(d)(1) pursuant to the exemptive relief obtained by the Trust, the registered investment company must enter into an agreement with the Trust.

Book Entry. Shares of the Fund are held in book-entry form, which means that no stock certificates are issued. The Depository Trust Company (“DTC”) or its nominee is the record owner of all outstanding shares of the Fund and is recognized as the owner of all shares for all purposes.

Investors owning shares of the Fund are beneficial owners as shown on the records of DTC or its participants. DTC serves as the securities depository for shares of the Fund. DTC participants include securities brokers and dealers, banks, trust companies, clearing corporations and other institutions that directly or indirectly maintain a custodial relationship with DTC. As a beneficial owner of shares, you are not entitled to receive physical delivery of stock certificates or to have shares registered in your name, and you are not considered a registered owner of shares. Therefore, to exercise any right as an owner of shares, you must rely upon the procedures of DTC and its participants. These procedures are the same as those that apply to any other securities that you hold in book-entry or “street name” form.

Share Prices. The trading prices of the Fund’s shares in the secondary market generally differ from the Fund’s daily NAV and are affected by market forces such as supply and demand, economic conditions and other factors. Information regarding the intraday value of shares of the Fund, also known as the “indicative optimized portfolio value” (“IOPV”), is disseminated every 15 seconds throughout the trading day by the national securities exchange on which the Fund’s shares are listed or by market data vendors or other information providers. The IOPV is based on the current market value of the securities and/or cash required to be deposited in exchange for a Creation Unit. The IOPV does not necessarily reflect the precise composition of the current portfolio of securities held by the Fund at a particular point in time or the best possible valuation of the current portfolio. Therefore, the IOPV should not be viewed as a “real-time” update of the Fund’s NAV, which is computed only once a day. The IOPV is generally determined by using both current market quotations and/or price quotations obtained from broker-dealers that may trade in the portfolio securities held by the Fund. The quotations of certain Fund holdings may not be updated during U.S. trading hours if such holdings do not trade in the United States. The Fund is not involved in, or responsible for, the calculation or dissemination of the IOPV and makes no representation or warranty as to its accuracy.

Determination of Net Asset Value. The NAV of the Fund normally is determined once daily Monday through Friday, generally as of the regularly scheduled close of business of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m., Eastern time) on each day that the NYSE is open for trading, based on prices at the time of closing provided that (a) any Fund assets or liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers (as detailed below) and (b) U.S. fixed income assets may be valued as of the announced closing time for trading in fixed income instruments in a particular market or exchange. The NAV

of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets held by the Fund, and its liabilities, are determined pursuant to valuation policies and procedures approved by the Board. The Fund’s assets and liabilities are valued primarily on the basis of market quotations.

Equity investments are valued at market value, which is generally determined using the last reported official closing price or last trading price on the exchange or market on which the security is primarily traded at the time of valuation.

The Fund invests in foreign securities. Foreign currency exchange rates are generally determined as of 4:00 p.m., London time. Foreign securities owned by the Fund may trade on weekends or other days when the Fund does not price its shares. As a result, the Fund’s NAV may change on days when Authorized Participants will not be able to purchase or redeem Fund shares.

Generally, trading in foreign securities, U.S. government securities, money market instruments and certain fixed-income securities is substantially completed each day at various times prior to the close of business on the NYSE. The values of such securities used in computing the NAV of the Fund are determined as of such times.

When market quotations are not readily available or are believed by BFA to be unreliable, the Fund’s investments are valued at fair value. Fair value determinations are made by BFA in accordance with policies and procedures approved by the Fund’s Board. BFA may conclude that a market quotation is not readily available or is unreliable if a security or other asset or liability does not have a price source due to its lack of liquidity, if a market quotation differs significantly from recent price quotations or otherwise no longer appears to reflect fair value, where the security or other asset or liability is thinly traded, or where there is a significant event subsequent to the most recent market quotation. A “significant event” is an event that, in the judgment of BFA, is likely to cause a material change to the closing market price of the asset or liability held by the Fund. Foreign securities whose values are affected by volatility that occurs in U.S. markets on a trading day after the close of foreign securities markets may be fair valued.

Fair value represents a good faith approximation of the value of an asset or liability. The fair value of an asset or liability held by the Fund is the amount the Fund might reasonably expect to receive from the current sale of that asset or the cost to extinguish that liability in an arm’s-length transaction. Valuing the Fund’s investments using fair value pricing will result in prices that may differ from current market valuations and that may not be the price at which those investments could have been sold during the period in which the particular fair values were used. Use of fair value prices and certain current market valuations could result in a difference between the prices used to calculate the Fund’s NAV and the prices used by the Underlying Index, which, in turn, could result in a difference between the Fund’s performance and the performance of the Underlying Index.

The value of assets or liabilities denominated in non-U.S. currencies will be converted into U.S. dollars using exchange rates deemed appropriate by BFA as investment

adviser. Use of a rate different from the rate used by the Index Provider may adversely affect the Fund’s ability to track the Underlying Index.

Dividends and Distributions

General Policies. Dividends from net investment income, if any, generally are declared and paid semi-annually by the Fund. Distributions of net realized securities gains, if any, generally are declared and paid once a year, but the Trust may make distributions on a more frequent basis for the Fund. The Trust reserves the right to declare special distributions if, in its reasonable discretion, such action is necessary or advisable to preserve its status as a regulated investment company (“RIC”) or to avoid imposition of income or excise taxes on undistributed income or realized gains.

Dividends and other distributions on shares of the Fund are distributed on a pro rata basis to beneficial owners of such shares. Dividend payments are made through DTC participants and indirect participants to beneficial owners then of record with proceeds received from the Fund.

Dividend Reinvestment Service. No dividend reinvestment service is provided by the Trust. Broker-dealers may make available the DTC book-entry Dividend Reinvestment Service for use by beneficial owners of the Fund for reinvestment of their dividend distributions. Beneficial owners should contact their broker to determine the availability and costs of the service and the details of participation therein. Brokers may require beneficial owners to adhere to specific procedures and timetables. If this service is available and used, dividend distributions of both income and realized gains will be automatically reinvested in additional whole shares of the Fund purchased in the secondary market.

Taxes. As with any investment, you should consider how your investment in shares of the Fund will be taxed. The tax information in this Prospectus is provided as general information, based on current law. You should consult your own tax professional about the tax consequences of an investment in shares of the Fund.

Unless your investment in Fund shares is made through a tax-exempt entity or tax-deferred retirement account, such as an IRA, you need to be aware of the possible tax consequences when the Fund makes distributions or you sell Fund shares.

Taxes on Distributions. Distributions from the Fund’s net investment income (other than qualified dividend income), including distributions of income from securities lending and distributions out of the Fund’s net short-term capital gains, if any, are taxable to you as ordinary income. Distributions by the Fund of net long-term capital gains in excess of net short-term capital losses (capital gain dividends) are taxable to you as long-term capital gains, generally at a 15% tax rate (0% at certain income levels), regardless of how long you have held the Fund’s shares. Distributions by the Fund that qualify as qualified dividend income are taxable to you at long-term capital gain rates for taxable years beginning on or before December 31, 2012. The 15% and 0% tax rates expire for taxable years beginning after December 31, 2012. Maximum long-term capital gain income tax rates are scheduled to rise to 20% in 2013. Beginning in 2013, a 3.8% U.S. federal Medicare contribution tax will be imposed on “net investment income,” including interest, dividends, and capital gains, of U.S.

individuals with income exceeding $200,000 (or $250,000 if married and filing jointly), and of estates and trusts.

Dividends will be qualified dividend income to you if they are attributable to qualified dividend income received by the Fund. Generally, qualified dividend income includes dividend income from taxable U.S. corporations and qualified non-U.S. corporations, provided that the Fund satisfies certain holding period requirements in respect of the stock of such corporations and has not hedged its position in the stock in certain ways. Substitute dividends received by the Fund with respect to dividends paid on securities lent out will not be qualified dividend income. For this purpose, a qualified non-U.S. corporation means any non-U.S. corporation that is eligible for benefits under a comprehensive income tax treaty with the United States, which includes an exchange of information program or if the stock with respect to which the dividend was paid is readily tradable on an established United States securities market. The term excludes a corporation that is a passive foreign investment company.

Dividends received by the Fund from a REIT or another RIC generally are qualified dividend income only to the extent the dividend distributions are made out of qualified dividend income received by such REIT or RIC. It is expected that dividends received by the Fund from a REIT and distributed to a shareholder generally will be taxable to the shareholder as ordinary income.

For a dividend to be treated as qualified dividend income, the dividend must be received with respect to a share of stock held without being hedged by the Fund, and with respect to a share of the Fund held without being hedged by you, for 61 days during the 121-day period beginning at the date which is 60 days before the date on which such share becomes ex-dividend with respect to such dividend or, in the case of certain preferred stock, 91 days during the 181-day period beginning 90 days before such date.

If your Fund shares are loaned out pursuant to a securities lending arrangement, you may lose the ability to use foreign tax credits passed through by the Fund or to treat Fund dividends paid while the shares are held by the borrower as qualified dividend income.

In general, your distributions are subject to U.S. federal income tax for the year when they are paid. Certain distributions paid in January, however, may be treated as paid on December 31 of the prior year.

If the Fund’s distributions exceed current and accumulated earnings and profits, all or a portion of the distributions made in the taxable year may be recharacterized as a return of capital to shareholders. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and result in a higher capital gain or lower capital loss when those shares on which the distribution was received are sold. Once a shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain, if the shareholder holds shares of the Fund as capital assets.

If you are neither a resident nor a citizen of the United States or if you are a non-U.S. entity, the Fund’s ordinary income dividends (which include distributions of net short-term capital gains) will generally be subject to a 30% U.S. withholding tax, unless a lower treaty rate applies, provided that withholding tax will generally not apply to any

gain or income realized by a non-U.S. shareholder in respect of any distributions of long-term capital gains or upon the sale or other disposition of shares of the Fund.

A 30% withholding tax will be imposed on dividends paid after December 31, 2013, and redemption proceeds paid after December 31, 2014, to (i) foreign financial institutions including non-U.S. investment funds unless they agree to collect and disclose to the Internal Revenue Service (“IRS”) information regarding their direct and indirect U.S. account holders and (ii) certain other foreign entities, unless they certify certain information regarding their direct and indirect U.S. owners. To avoid withholding, foreign financial institutions will need to enter into agreements with the IRS that state that they will provide the IRS information, including the name, address and taxpayer identification number of direct and indirect U.S. account holders, comply with due diligence procedures with respect to the identification of U.S. accounts, report to the IRS certain information with respect to U.S. accounts maintained, agree to withhold tax on certain payments made to non-compliant foreign financial institutions or to account holders who fail to provide the required information, and determine certain other information as to their account holders. Other foreign entities will need to provide the name, address, and taxpayer identification number of each substantial U.S. owner or certifications of no substantial U.S. ownership unless certain exceptions apply.

Dividends, interest and capital gains earned by the Fund with respect to non-U.S. securities may give rise to withholding and other taxes imposed by non-U.S. countries. Tax conventions between certain countries and the United States may reduce or eliminate such taxes. If more than 50% of the total assets of the Fund at the close of a year consists of non-U.S. stocks or securities, the Fund may “pass through” to you certain non-U.S. income taxes (including withholding taxes) paid by the Fund. This means that you would be considered to have received as an additional dividend your share of such non-U.S. taxes, but you may be entitled to either a corresponding tax deduction in calculating your taxable income, or, subject to certain limitations, a credit in calculating your U.S. federal income tax.

For purposes of foreign tax credits for U.S. shareholders of the Fund, foreign capital gains taxes may not produce associated foreign source income, thereby limiting a U.S. person’s ability to use such credits.

If you are a resident or a citizen of the United States, by law, back-up withholding will apply to your distributions and proceeds if you have not provided a taxpayer identification number or social security number and made other required certifications.

Taxes When Shares are Sold. Currently, any capital gain or loss realized upon a sale of Fund shares is generally treated as a long-term gain or loss if the shares have been held for more than one year. Any capital gain or loss realized upon a sale of Fund shares held for one year or less is generally treated as short-term gain or loss, except that any capital loss on the sale of shares held for six months or less is treated as long-term capital loss to the extent that capital gain dividends were paid with respect to such shares. Beginning in 2013, any such capital gains, including from sales of Fund shares or from capital gain dividends, will be included in “net investment income” for purposes of the 3.8% U.S. federal Medicare contribution tax mentioned above.

The foregoing discussion summarizes some of the consequences under current U.S. federal tax law of an investment in the Fund. It is not a substitute for personal tax advice. You may also be subject to state and local taxation on Fund distributions and sales of shares. Consult your personal tax adviser about the potential tax consequences of an investment in shares of the Fund under all applicable tax laws.

Creations and Redemptions. Prior to trading in the secondary market, shares of the Fund are “created” at NAV by market makers, large investors and institutions only in block-size Creation Units of 50,000 shares or multiples thereof. Each “creator” or “Authorized Participant” enters into an authorized participant agreement with the Fund’s distributor, SEI Investments Distribution Co. (the “Distributor”). Only an Authorized Participant may create or redeem Creation Units directly with the Fund. A creation transaction, which is subject to acceptance by the transfer agent, generally takes place when an Authorized Participant deposits into the Fund a designated portfolio of securities and a specified amount of cash approximating the holdings of the Fund in exchange for a specified number of Creation Units. To the extent practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund.

Similarly, shares can be redeemed only in Creation Units, generally for a designated portfolio of securities and a specified amount of cash held by the Fund (“Fund Securities”). Except when aggregated in Creation Units, shares are not redeemable by the Fund. The prices at which creations and redemptions occur are based on the next calculation of NAV after an order is received in a form described in the authorized participant agreement.

The Fund intends to comply with the U.S. federal securities laws in accepting securities for deposit and satisfying redemptions with redemption securities by, among other means, assuring that any securities accepted for deposit and any securities used to satisfy redemption requests will be sold in transactions that would be exempt from registration under the Securities Act of 1933, as amended (the “1933 Act”). Further, an Authorized Participant that is not a “qualified institutional buyer,” as such term is defined under Rule 144A of the 1933 Act, will not be able to receive Fund Securities that are restricted securities eligible for resale under Rule 144A.

Creations and redemptions must be made through a firm that is either a member of the Continuous Net Settlement System of the National Securities Clearing Corporation or a DTC participant and has executed an agreement with the Distributor with respect to creations and redemptions of Creation Unit aggregations. Information about the procedures regarding creation and redemption of Creation Units (including the cut-off times for receipt of creation and redemption orders) is included in the Fund’s SAI.

Because new shares may be created and issued on an ongoing basis, at any point during the life of the Fund a “distribution,” as such term is used in the 1933 Act, may be occurring. Broker-dealers and other persons are cautioned that some activities on their part may, depending on the circumstances, result in their being deemed participants in a distribution in a manner that could render them statutory underwriters and subject to the prospectus delivery and liability provisions of the 1933 Act. Any determination of whether one is an underwriter must take into account all the relevant facts and circumstances of each particular case.

Broker-dealers should also note that dealers who are not “underwriters” but are participating in a distribution (as contrasted to ordinary secondary transactions), and thus dealing with shares that are part of an “unsold allotment” within the meaning of Section 4(3)(C) of the 1933 Act, would be unable to take advantage of the prospectus delivery exemption provided by Section 4(3) of the 1933 Act. For delivery of prospectuses to exchange members, the prospectus delivery mechanism of Rule 153 under the 1933 Act is available only with respect to transactions on a national securities exchange.

Costs Associated with Creations and Redemptions. Authorized Participants are charged standard creation and redemption transaction fees to offset transfer and other transaction costs associated with the issuance and redemption of Creation Units. The standard creation and redemption transaction fees are set forth in the table below. The standard creation transaction fee is charged to the Authorized Participant on the day such Authorized Participant creates a Creation Unit, and is the same regardless of the number of Creation Units purchased by the Authorized Participant on the applicable business day. Similarly, the standard redemption transaction fee is charged to the Authorized Participant on the day such Authorized Participant redeems a Creation Unit, and is the same regardless of the number of Creation Units redeemed by the Authorized Participant on the applicable business day. Creations and redemptions for cash (when cash creations and redemptions (in whole or in part) are available or specified) are also subject to an additional charge (up to the maximum amounts shown in the table below). This charge is intended to compensate for brokerage, tax, foreign exchange, execution, market impact and other costs and expenses related to cash transactions. Investors who use the services of a broker or other financial intermediary may pay fees for such services.

The following table shows, as of September 30, 2011, the approximate value of one Creation Unit, standard fees and maximum additional charges for creations and redemptions (as described above):

Householding. Householding is an option available to certain Fund investors. Householding is a method of delivery, based on the preference of the individual investor, in which a single copy of certain shareholder documents can be delivered to investors who share the same address, even if their accounts are registered under different names. Please contact your broker-dealer if you are interested in enrolling in householding and receiving a single copy of prospectuses and other shareholder documents, or if you are currently enrolled in householding and wish to change your householding status.

Distribution

The Distributor distributes Creation Units for the Fund on an agency basis. The Distributor does not maintain a secondary market in shares of the Fund. The Distributor has no role in determining the policies of the Fund or the securities that are purchased or sold by the Fund. The Distributor’s principal address is One Freedom Valley Drive, Oaks, PA 19456.

In addition, BFA or its Affiliates make payments to broker-dealers, banks or other financial intermediaries (together, “intermediaries”) related to marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems, or their making shares of the Fund and certain other iShares funds available to their customers. Such payments, which may be significant to the intermediary, are not made by the Fund. Rather, such payments are made by BFA or its Affiliates from their own resources, which come directly or indirectly in part from fees paid by the iShares funds complex. Payments of this type are sometimes referred to as revenue-sharing payments. A financial intermediary may make decisions about which investment options it recommends or makes available, or the level of services provided, to its customers based on the revenue-sharing payments it is eligible to receive. Therefore, such payments to an intermediary create conflicts of interest between the intermediary and its customers and may cause the intermediary to recommend the Fund or other iShares funds over another investment. More information regarding these payments is contained in the Fund’s SAI. Please contact your salesperson or other investment professional for more information regarding any such payments his or her firm may receive from BFA or its Affiliates.

Financial Highlights

The financial highlights table is intended to help investors understand the Fund’s financial performance since inception. Certain information reflects financial results for a single share of the Fund. The total returns in the table represent the rate that an investor would have earned (or lost) on an investment in the Fund, assuming reinvestment of all dividends and distributions. This information has been audited by PricewaterhouseCoopers LLP, whose report is included, along with the Fund’s financial statements, in the Fund’s Annual Report (available upon request).

Supplemental Information

I. Premium/Discount Information

The table that follows presents information about the differences between the daily market price on secondary markets for shares of the Fund and the Fund’s NAV. NAV is the price at which the Fund issues and redeems shares. It is calculated in accordance with the standard formula for valuing mutual fund shares. The price used to calculate market returns (“Market Price”) of the Fund generally is determined using the midpoint between the highest bid and the lowest offer on the primary securities exchange on which shares of the Fund are listed for trading, as of the time that the Fund’s NAV is calculated. The Fund’s Market Price may be at, above or below its NAV. The NAV of the Fund will fluctuate with changes in the value of its portfolio holdings. The Market Price of the Fund will fluctuate in accordance with changes in its NAV, as well as market supply and demand.

Premiums or discounts are the differences (expressed as a percentage) between the NAV and Market Price of the Fund on a given day, generally at the time the NAV is calculated. A premium is the amount that the Fund is trading above the reported NAV, expressed as a percentage of the NAV. A discount is the amount that the Fund is trading below the reported NAV, expressed as a percentage of the NAV.

The following information shows the frequency of distributions of premiums and discounts for the Fund from April 1, 2010 through September 30, 2011.

Each line in the table shows the number of trading days in which the Fund traded within the premium/discount range indicated. The number of trading days in each premium/discount range is also shown as a percentage of the total number of trading days in the period covered by the table. All data presented here represents past performance, which cannot be used to predict future results.

Premium/Discount Range
Number of Days
Percentage of Total Days
Greater than 2.5% and Less than 3.0% 1 0.26%
Greater than 2.0% and Less than 2.5% 2 0.53
Greater than 1.5% and Less than 2.0% 8 2.11
Greater than 1.0% and Less than 1.5% 26 6.84
Greater than 0.5% and Less than 1.0% 135 35.53

Less than -0.5% and Greater than -1.0% 30 7.89
Less than -1.0% and Greater than -1.5% 11 2.89
Less than -1.5% and Greater than -2.0% 7 1.84
Less than -2.0% 3 0.79
   380 100.00%

II. Total Return Information

The table that follows presents information about the total returns of the Fund and the Underlying Index as of the fiscal year ended July 31, 2011.

“Average Annual Total Returns” represent the average annual change in value of an investment over the periods indicated. “Cumulative Total Returns” represent the total change in value of an investment over the period indicated.

The Fund’s NAV is the value of one share of the Fund as calculated in accordance with the standard formula for valuing mutual fund shares. The NAV return is based on the NAV of the Fund and the market return is based on the Market Price of the Fund. Market Price is determined by using the midpoint between the highest bid and the lowest offer on the primary stock exchange on which shares of the Fund are listed for trading, as of the time that the Fund’s NAV is calculated. Since shares of the Fund did not trade in the secondary market until after the Fund’s inception, for the period from inception to the first day of secondary market trading in shares of the Fund, the NAV of the Fund is used as a proxy for the Market Price to calculate market returns. Market and NAV returns assume that dividends and capital gain distributions have been reinvested in the Fund at Market Price and NAV, respectively.

An index is a statistical composite that tracks a specified financial market or sector. Unlike the Fund, the Underlying Index does not actually hold a portfolio of securities and therefore does not incur the expenses incurred by the Fund. These expenses negatively impact the performance of the Fund. Also, market returns do not include brokerage commissions that may be payable on secondary market transactions. If brokerage commissions were included, market returns would be lower. The returns shown in the following table do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption or sale of Fund shares. The investment return and principal value of shares of the Fund will vary with changes in market conditions. Shares of the Fund may be worth more or less than their original cost when they are redeemed or sold in the market. The Fund’s past performance is no guarantee of future results.

Fund Overview

iSHARES® MSCI ACWI ex US HEALTH CARE SECTOR INDEX FUND

Ticker: AXHE Stock Exchange: NYSE Arca

Investment Objective

The iShares MSCI ACWI ex US Health Care Sector Index Fund (the “Fund”) seeks investment results that correspond generally to the price and yield performance, before fees and expenses, of the MSCI All Country World ex USA Health Care Index (the “Underlying Index”).

Fees and Expenses

The following table describes the fees and expenses that you will incur if you own shares of the Fund. The investment advisory agreement between iShares Trust (the “Trust”) and BlackRock Fund Advisors (“BFA”) (the “Investment Advisory Agreement”) provides that BFA will pay all operating expenses of the Fund, except interest expenses, taxes, brokerage expenses, future distribution fees or expenses, and extraordinary expenses.

You may also incur usual and customary brokerage commissions when buying or selling shares of the Fund, which are not reflected in the example that follows:

Annual Fund Operating Expenses

Example. This Example is intended to help you compare the cost of owning shares of the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

Portfolio Turnover. The Fund may pay transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 8% of the average value of its portfolio.

Principal Investment Strategies

The Underlying Index is a free float-adjusted market capitalization-weighted index designed to measure the combined equity market performance of the health care sector of developed and emerging markets countries, excluding the United States. Component securities include those of health care equipment, health care services, pharmaceutical, biotechnology and life sciences companies. As of September 30, 2011, the Underlying Index consisted of companies in the following countries and regions: Australia, Austria, Belgium, Brazil, Canada, Chile, China, Colombia, the Czech Republic, Denmark, Egypt, Finland, France, Germany, Greece, Hong Kong, Hungary, India, Indonesia, Ireland, Israel, Italy, Japan, Malaysia, Mexico, Morocco, the Netherlands, New Zealand, Norway, Peru, the Philippines, Poland, Portugal, Russia, Singapore, South Africa, South Korea, Spain, Sweden, Switzerland, Taiwan, Thailand, Turkey and the United Kingdom (together, the “ACWI ex US health care sector countries”). As of September 30, 2011, the Underlying Index was comprised of 75 securities.

BFA uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to “beat” the index it tracks and does not seek temporary defensive positions when markets decline or appear overvalued.

Indexing may eliminate the chance that the Fund will substantially outperform the Underlying Index but also may reduce some of the risks of active management, such as poor security selection. Indexing seeks to achieve lower costs and better after-tax performance by keeping portfolio turnover low in comparison to actively managed investment companies.

BFA uses a representative sampling indexing strategy to manage the Fund. “Representative sampling” is an indexing strategy that involves investing in a representative sample of securities that collectively has an investment profile similar to the Underlying Index. The securities selected are expected to have, in the aggregate, investment characteristics (based on factors such as market capitalization and industry weightings), fundamental characteristics (such as return variability and yield) and liquidity measures similar to those of the Underlying Index. The Fund may or may not hold all of the securities in the Underlying Index.

The Fund generally invests at least 80% of its assets in securities of the Underlying Index or in depositary receipts representing securities of the Underlying Index. The Fund may invest the remainder of its assets in securities not included in the Underlying Index,

S-2   


Table Of Contents



but which BFA believes will help the Fund track the Underlying Index and in other investments including futures contracts, options on futures contracts, options and swaps related to the Underlying Index, as well as cash and cash equivalents, including shares of money market funds advised by BFA or its affiliates.

The Fund may lend securities representing up to one-third of the value of the Fund’s total assets (including the value of the collateral received).

The Underlying Index is sponsored by an organization (the “Index Provider”) that is independent of the Fund and BFA. The Index Provider determines the composition and relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index. The Fund’s Index Provider is MSCI Inc. (“MSCI”).

Industry Concentration Policy. The Fund will concentrate its investments (i.e., hold 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. For purposes of this limitation, securities of the U.S. government (including its agencies and instrumentalities) and repurchase agreements collateralized by U.S. government securities are not considered to be issued by members of any industry.

Summary of Principal Risks

As with any investment, you could lose all or part of your investment in the Fund, and the Fund’s performance could trail that of other investments. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund’s net asset value per share (“NAV”), trading price, yield, total return and ability to meet its investment objective.

Asset Class Risk. Securities in the Underlying Index or in the Fund’s portfolio may underperform in comparison to the general securities markets or other asset classes.

Biotechnology Sector Risk. Biotechnology companies face intense competition and the potential for rapid product obsolescence. Biotechnology companies may be adversely affected by the loss or impairment of intellectual property rights or changes in government regulations.

Concentration Risk. To the extent that the Fund’s investments are concentrated in a particular issuer, region, country, market, industry or asset class, the Fund may be susceptible to loss due to adverse occurrences affecting that issuer, region, country, market, industry or asset class.

Currency Risk. Because the Fund’s NAV is determined in U.S. dollars, the Fund’s NAV could decline if the currency of a non-U.S. market in which the Fund invests depreciates against the U.S. dollar.

Custody Risk. Less developed markets are more likely to experience problems with the clearing and settling of trades and the holding of securities by local banks, agents and depositories.

Emerging Markets Risk. The Fund’s investments in emerging markets may be subject to a greater risk of loss than investments in more developed markets. Emerging markets may be more likely to experience inflation risk,

S-3   


Table Of Contents



political turmoil and rapid changes in economic conditions than more developed markets. Emerging markets often have less uniformity in accounting and reporting requirements, unreliable securities valuation and greater risk associated with custody of securities.

Equity Securities Risk. Equity securities are subject to changes in value and their values may be more volatile than other asset classes.

Geographic Risk. A natural or other disaster could occur in a geographic region in which the Fund invests, which could affect the economy or particular business operations of companies in the specific geographic region, causing an adverse impact on the Fund’s investments in the affected region.

Healthcare Sector Risk. The healthcare sector may be affected by government regulations and government healthcare programs, increases or decreases in the cost of medical products and services and product liability claims, among other factors. Many healthcare companies are heavily dependent on patent protection and the expiration of a patent may adversely affect their profitability. Healthcare companies are subject to competitive forces that may result in price discounting, and may be thinly capitalized and susceptible to product obsolescence.

Issuer Risk. Fund performance depends on the performance of individual securities to which the Fund has exposure. Changes to the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA’s investment management strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares, losses from trading in secondary markets, periods of high volatility and disruption in the creation/redemption process of the Fund. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV.

Medical Equipment Industry Risk. Many companies in the medical equipment industry are affected by the expiration of patents, litigation based on product liability, industry competition, product obsolescence and regulatory approvals, among other factors.

Mid-Capitalization Companies Risk. The Fund may invest in the securities of mid-capitalization companies. Compared to large-capitalization companies, mid-capitalization companies may be less stable and more susceptible to adverse developments and their securities may be more volatile and less liquid.

Non-Diversification Risk. The Fund may invest a large percentage of its assets in securities issued by or representing a small number of issuers. As a result, the Fund’s performance may depend on the performance of a small number of issuers.

Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers are subject to the risks associated with

investing in those non-U.S. markets, such as heightened risks of inflation or nationalization. The Fund may lose money due to political, economic and geographic events affecting a non-U.S. issuer or market. The Fund is specifically exposed to European Economic Risk.

Passive Investment Risk. The Fund is not actively managed and BFA does not attempt to take defensive positions under any market conditions, including declining markets.

Pharmaceuticals Industry Risk. Companies in the pharmaceuticals industry may be affected by industry competition, dependencies on a limited number of products, obsolescence of products, government approvals and regulations, patent expiration and litigation regarding product liability.

Privatization Risk. Some countries in which the Fund invests have begun a process of privatizing certain entities and industries. Privatized entities may lose money or be re-nationalized.

Reliance on Trading Partners Risk. The Fund invests in countries whose economies are heavily dependent upon trading with key partners. Any reduction in this trading may have an adverse impact on the Fund’s investments. Through its trading partners, the Fund is particularly exposed to U.S. Trading Partner Risk.

Risk of Investing in Switzerland. The Fund’s investment in Swiss issuers may subject the Fund to legal, regulatory, political, currency, security, and economic risk specific to Switzerland. International trade is a large component of the Swiss economy and Switzerland depends upon exports to generate economic growth. The Swiss economy relies on certain key trading partners in order to sustain continued economic growth. Switzerland’s economic growth mirrors slowdowns and growth spurts experienced in other countries, including the United States and certain Western European countries. A prolonged economic slowdown in these countries is likely to have a negative impact on the Swiss economy and the issuers to which the Fund has exposure.

Risk of Investing in the United Kingdom. The Fund’s investment in British issuers may subject the Fund to regulatory, political, currency, security, and economic risk specific to the United Kingdom. The United Kingdom has one of the largest economies in Europe, and the United States and other European countries are substantial trading partners of the United Kingdom. As a result, the British economy may be impacted by changes to the economic health of the United States and other European countries. The British economy, along with certain other European economies, experienced a significant economic slowdown during the recent financial crisis; certain British financial institutions were severely under-capitalized and required government intervention to survive.

Securities Lending Risk. The Fund may engage in securities lending. Securities lending involves the risk that the Fund may lose money because the borrower of the Fund’s loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Security Risk. Some countries and regions in which the Fund invests have experienced security concerns. Incidents involving a country’s or region’s security may cause uncertainty in these markets and may adversely affect their economies and the Fund’s investments.

Small-Capitalization Companies Risk. The Fund may invest in the securities of small-capitalization companies. Compared to mid- and large-capitalization companies, small-capitalization companies may be less stable and more susceptible to adverse developments and their securities may be more volatile and less liquid.

Structural Risk. The countries in which the Fund invests may be subject to considerable degrees of economic, political and social instability.

Tracking Error Risk. The performance of the Fund may diverge from that of the Underlying Index. Because the Fund employs a representative sampling strategy, the Fund may experience tracking error to a greater extent than a fund that seeks to replicate an index.

Valuation Risk. The value of the securities in the Fund’s portfolio may change on days when shareholders will not be able to purchase or sell the Fund’s shares.

Performance Information

As of the date of the Fund’s prospectus (the “Prospectus”), the Fund has been in operation for less than one full calendar year and therefore does not report its performance information.

Management

Investment Adviser. BlackRock Fund Advisors.

Portfolio Managers. Rene Casis, Diane Hsiung and Greg Savage (the “Portfolio Managers”) are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager supervises a portfolio management team. Mr. Casis has been a Portfolio Manager of the Fund since 2010. Ms. Hsiung and Mr. Savage have been Portfolio Managers of the Fund since inception.

Purchase and Sale of Fund Shares

The Fund is an exchange-traded fund (commonly referred to as an “ETF”). Individual Fund shares may only be purchased and sold on a national securities exchange through a broker-dealer. The price of Fund shares is based on market price, and because ETF shares trade at market prices rather than NAV, shares may trade at a price greater than NAV (a premium) or less than NAV (a discount). The Fund will only issue or redeem shares that have been aggregated into blocks of 50,000 shares or multiples thereof (“Creation Units”) to authorized participants who have entered into agreements with the Fund’s distributor. The Fund generally will issue or redeem Creation Units in return for a designated portfolio of securities (and an amount of cash) that the Fund specifies each day.

Tax Information

The Fund intends to make distributions that may be taxable to you as ordinary income or capital gains, unless you are investing through a tax-deferred arrangement such as a 401(k) plan or an individual retirement account (“IRA”).

Payments to Broker-Dealers and other Financial Intermediaries

If you purchase shares of the Fund through a broker-dealer or other financial intermediary (such as a bank), BFA or other related companies may pay the intermediary for marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems or other services related to the sale or promotion of the Fund. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.

More Information About the Fund

This Prospectus contains important information about investing in the Fund. Please read this Prospectus carefully before you make any investment decisions. Additional information regarding the Fund is available at www.iShares.com.

BFA is the investment adviser to the Fund. Shares of the Fund are listed for trading on NYSE Arca, Inc. (“NYSE Arca”). The market price for a share of the Fund may be different from the Fund’s most recent NAV.

ETFs are funds that trade like other publicly-traded securities. The Fund is designed to track an index. Similar to shares of an index mutual fund, each share of the Fund represents a partial ownership in an underlying portfolio of securities intended to track a market index. Unlike shares of a mutual fund, which can be bought and redeemed from the issuing fund by all shareholders at a price based on NAV, shares of the Fund may be purchased or redeemed directly from the Fund at NAV solely by authorized participants. Also unlike shares of a mutual fund, shares of the Fund are listed on a national securities exchange and trade in the secondary market at market prices that change throughout the day.

The Fund invests in a particular segment of the securities markets and seeks to track the performance of a securities index that generally is not representative of the market as a whole. The Fund is designed to be used as part of broader asset allocation strategies. Accordingly, an investment in the Fund should not constitute a complete investment program.

An index is a theoretical financial calculation while the Fund is an actual investment portfolio. The performance of the Fund and the Underlying Index may vary due to transaction costs, non-U.S. currency valuations, asset valuations, corporate actions (such as mergers and spin-offs), timing variances and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions (such as diversification requirements) that apply to the Fund but not to the Underlying Index or to the use of representative sampling. “Tracking error” is the difference between the performance (return) of the Fund’s portfolio and that of the Underlying Index. BFA expects that, over time, the Fund’s tracking error will not exceed 5%. Because the Fund uses a representative sampling indexing strategy, it can be expected to have a larger tracking error than if it used a replication indexing strategy. “Replication” is an indexing strategy in which a fund invests in substantially all of the securities in its underlying index in approximately the same proportions as in the underlying index.

An investment in the Fund is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, BFA or any of its affiliates.

The Fund’s investment objective and the Underlying Index may be changed without shareholder approval.

A Further Discussion of Principal Risks

The Fund is subject to various risks, including the principal risks noted below, any of which may adversely affect the Fund’s NAV, trading price, yield, total return and ability to meet its investment objective. You could lose all or part of your investment in the Fund, and the Fund could underperform other investments.

Asset Class Risk. The securities in the Underlying Index or in the Fund’s portfolio may underperform the returns of other securities or indexes that track other countries, groups of countries, regions, industries, groups of industries, markets, asset classes or sectors. Various types of securities or indexes tend to experience cycles of outperformance and underperformance in comparison to the general securities markets.

Biotechnology Sector Risk. Companies in the biotechnology industry spend heavily on research and development and their products or services may not prove commercially successful or may become obsolete quickly. The biotechnology industry may be subject to greater governmental regulation than other industries and changes in governmental policies and the need for regulatory approvals may have a material adverse effect on this industry. Companies in the biotechnology industry are subject to risks of new technologies and competitive pressures and are heavily dependent on patents and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies.

Concentration Risk. To the extent that the Fund’s portfolio reflects the Underlying Index’s concentration in the securities of a particular issuer or issuers in a particular country, group of countries, region, market, industry, group of industries, sector or asset class, the Fund may be adversely affected by the performance of those securities, may be subject to increased price volatility and may be more susceptible to adverse economic, market, political or regulatory occurrences affecting that issuer, country, group of countries, region, market, industry, group of industries, sector or asset class.

Currency Risk. Because the Fund’s NAV is determined on the basis of the U.S. dollar, investors may lose money if the currency of a non-U.S. market in which the Fund invests depreciates against the U.S. dollar, even if the local currency value of the Fund’s holdings in that market increases.

Custody Risk. Custody risk refers to the risks inherent in the process of clearing and settling trades and the holding of securities by local banks, agents and depositories. Low trading volumes and volatile prices in less developed markets may make trades harder to complete and settle, and governments or trade groups may compel local agents to hold securities in designated depositories that are not subject to independent evaluation. Local agents are held only to the standards of care of their local markets. In general, the less developed a country’s securities market is, the greater the likelihood of custody problems.

Emerging Markets Risk. Investments in emerging markets are subject to a greater risk of loss than investments in more developed markets. This is due to, among other things, the potential for greater market volatility, lower trading volume, inflation, political and economic instability, greater risk of a market shutdown and more

governmental limitations on foreign investments than typically found in more developed markets. In addition, emerging markets often have less uniformity in accounting and reporting requirements, unreliable securities valuation and greater risks associated with custody of securities.

Equity Securities Risk. The Fund invests in equity securities, which are subject to changes in value that may be attributable to market perception of a particular issuer or to general stock market fluctuations that affect all issuers. Investments in equity securities may be more volatile than investments in other asset classes.

European Economic Risk. The Economic and Monetary Union of the European Union (the “EU”) requires member countries to comply with restrictions on inflation rates, deficits, interest rates, debt levels and fiscal and monetary controls, each of which may significantly affect every country in Europe. Decreasing imports or exports, changes in governmental or EU regulations on trade, changes in the exchange rate of the euro, the default or threat of default by an EU member country on its sovereign debt, and/or an economic recession in an EU member country may have a significant adverse effect on the economies of EU member countries and their trading partners, including some or all of the ACWI ex US health care sector countries. The European financial markets have recently experienced volatility and have been adversely affected by concerns about economic downturns, credit rating downgrades, rising government debt levels and possible default on or restructuring of government debt in several European countries, including Greece, Ireland, Italy, Portugal and Spain. A default or debt restructuring by any European country would adversely impact holders of that country’s debt, and sellers of credit default swaps linked to that country’s creditworthiness, which may be located in countries other than those listed in the previous sentence. These events have adversely affected the value and exchange rate of the euro and may continue to significantly affect the economies of every country in Europe, including EU member countries that do not use the euro and non-EU member countries.

Geographic Risk. Some markets in which the Fund invests are located in parts of the world that have historically been prone to natural disasters, such as earthquakes, volcanoes, droughts, floods, hurricanes and tsunamis, and are economically sensitive to environmental events. Any natural or other disaster could have a significant adverse impact on the economies of these geographic areas, causing an adverse impact on the Fund’s investments in the affected region.

Healthcare Sector Risk. The profitability of companies in the healthcare sector may be affected by extensive government regulations, restrictions on government reimbursement for medical expenses, rising costs of medical products and services, pricing pressure, an increased emphasis on outpatient services, limited number of products, industry innovation, changes in technologies and other market developments. Many healthcare companies are heavily dependent on patent protection. The expiration of patents may adversely affect the profitability of these companies. Many healthcare companies are subject to extensive litigation based on product liability and similar claims. Healthcare companies are subject to competitive forces that may make it difficult to raise prices and, in fact, may result in price discounting. Many new products in the healthcare sector may be subject to regulatory

approvals. The process of obtaining such approvals may be long and costly. Companies in the healthcare sector may be thinly capitalized and may be susceptible to product obsolescence.

Issuer Risk. The performance of the Fund depends on the performance of individual securities to which the Fund has exposure. Any issuer of these securities may perform poorly, causing the value of its securities to decline. Poor performance may be caused by poor management decisions, competitive pressures, changes in technology, expiration of patent protection, disruptions in supply, labor problems or shortages, corporate restructurings, fraudulent disclosures or other factors. Issuers may, in times of distress or at their own discretion, decide to reduce or eliminate dividends, which may also cause their stock prices to decline.

Management Risk. The Fund may not fully replicate the Underlying Index and may hold securities not included in the Underlying Index. As a result, the Fund is subject to the risk that BFA’s investment management strategy, the implementation of which is subject to a number of constraints, may not produce the intended results.

Market Risk. The Fund could lose money due to short-term market movements and over longer periods during market downturns. Securities may decline in value due to factors affecting securities markets generally or particular industries represented in the markets. The value of a security may decline due to general market conditions, economic trends or events that are not specifically related to the issuer of the security or to factors that affect a particular industry or industries. During a general downturn in the securities markets, multiple asset classes may be negatively affected.

Market Trading Risk

Absence of Active Market. Although shares of the Fund are listed for trading on one or more stock exchanges, there can be no assurance that an active trading market for such shares will develop or be maintained.

Risk of Secondary Listings. The Fund’s shares may be listed or traded on U.S. and non-U.S. stock exchanges other than the U.S. stock exchange where the Fund’s primary listing is maintained. There can be no assurance that the Fund’s shares will continue to trade on any such stock exchange or in any market or that the Fund’s shares will continue to meet the requirements for listing or trading on any exchange or in any market. The Fund’s shares may be less actively traded in certain markets than others, and investors are subject to the execution and settlement risks and market standards of the market where they or their broker direct their trades for execution. Certain information available to investors who trade Fund shares on a U.S. stock exchange during regular U.S. market hours may not be available to investors who trade in other markets, which may result in secondary market prices in such markets being less efficient.

Secondary Market Trading Risk. Shares of the Fund may trade in the secondary market at times when the Fund does not accept orders to purchase or redeem shares. At such times, shares may trade in the secondary market with more significant premiums or discounts than might be experienced at times when the Fund accepts purchase and redemption orders.

Secondary market trading in Fund shares may be halted by a stock exchange because of market conditions or other reasons. In addition, trading in Fund shares on a stock exchange or in any market may be subject to trading halts caused by extraordinary market volatility pursuant to “circuit breaker” rules on the stock exchange or market. There can be no assurance that the requirements necessary to maintain the listing or trading of Fund shares will continue to be met or will remain unchanged.

Shares of the Fund May Trade at Prices Other Than NAV. Shares of the Fund trade on stock exchanges at prices at, above or below their most recent NAV. The NAV of the Fund is calculated at the end of each business day and fluctuates with changes in the market value of the Fund’s holdings since the most recent calculation. The trading prices of the Fund’s shares fluctuate continuously throughout trading hours based on market supply and demand rather than NAV. The trading prices of the Fund’s shares may deviate significantly from NAV during periods of market volatility. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV. However, because shares can be created and redeemed in Creation Units at NAV (unlike shares of many closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their NAVs), BFA believes that large discounts or premiums to the NAV of the Fund are not likely to be sustained over the long-term. While the creation/redemption feature is designed to make it likely that the Fund’s shares normally will trade on stock exchanges at prices close to the Fund’s next calculated NAV, exchange prices are not expected to correlate exactly with the Fund’s NAV due to timing reasons as well as market supply and demand factors. In addition, disruptions to creations and redemptions or extreme market volatility may result in trading prices for shares of the Fund that differ significantly from its NAV.

Costs of Buying or Selling Fund Shares. Buying or selling Fund shares on an exchange involves two types of costs that apply to all securities transactions. When buying or selling shares of the Fund through a broker, you will likely incur a brokerage commission or other charges imposed by brokers as determined by that broker. In addition, you may incur the cost of the “spread” – that is, the difference between what investors are willing to pay for Fund shares (the “bid” price) and the price at which they are willing to sell Fund shares (the “ask” price). Because of the costs inherent in buying or selling Fund shares, frequent trading may detract significantly from investment results and an investment in Fund shares may not be advisable for investors who anticipate regularly making small investments.

Medical Equipment Industry Risk. Many companies in the medical equipment industry are heavily dependent on patent protection, and the expiration of patents may adversely affect the profitability of these companies. Companies in the medical equipment industry may be subject to extensive litigation based on product liability and similar claims as well as competitive forces that may make it difficult to raise prices and, in fact, may result in price discounting. The profitability of some medical equipment companies may be dependent on a relatively limited number of products. In addition, their products can become obsolete due to industry innovation, changes in technologies or other market developments. Many new products in the medical

equipment industry are subject to regulatory approvals, and the process of obtaining such approvals may be long and costly.

Mid-Capitalization Companies Risk. Many of the companies in which the Fund invests are considered mid-capitalization companies. Stock prices of mid-capitalization companies may be more volatile than those of large-capitalization companies and, therefore, the Fund’s share price may be more volatile than those of funds that invest a larger percentage of their assets in stocks issued by large-capitalization companies. Stock prices of mid-capitalization companies are also more vulnerable than those of large-capitalization companies to adverse business or economic developments, and the stocks of mid-capitalization companies may be less liquid, making it difficult for the Fund to buy and sell them. In addition, mid-capitalization companies generally have less diverse product lines than large-capitalization companies and are more susceptible to adverse developments related to their products.

Non-Diversification Risk. The Fund is classified as “non-diversified.” This means that the Fund may invest a large percentage of its assets in securities issued by or representing a small number of issuers. As a result, the Fund may be more susceptible to the risks associated with these particular issuers, or to a single economic, political or regulatory occurrence affecting these issuers.

Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers are subject to all of the risks of investing in the markets where such issuers are located, including heightened risks of inflation or nationalization and market fluctuations caused by economic and political developments. As a result of investing in non-U.S. securities, the Fund may be subject to increased risk of loss caused by any of the factors listed below:

  • Lower levels of liquidity and market efficiency;
  • Greater securities price volatility;
  • Exchange rate fluctuations and exchange controls;
  • Less availability of public information about issuers;
  • Limitations on foreign ownership of securities;
  • Imposition of withholding or other taxes;
  • Imposition of restrictions on the expatriation of the funds or other assets of the Fund;
  • Higher transaction and custody costs and delays in settlement procedures;
  • Difficulties in enforcing contractual obligations;
  • Lower levels of regulation of the securities market;
  • Weaker accounting, disclosure and reporting requirements; and
  • Legal principles related to corporate governance, directors’ fiduciary duties and liabilities and stockholders’ rights in markets in which the Fund invests may differ and/or may not be as extensive or protective as those that apply in the United States.

Passive Investment Risk. The Fund is not actively managed and may be affected by a general decline in market segments related to the Underlying Index. The Fund invests

in securities included in, or representative of, the Underlying Index regardless of their investment merits. BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

Pharmaceuticals Industry Risk. Companies in the pharmaceuticals industry are subject to competitive forces that may make it difficult to raise prices and, in fact, may result in price discounting. The profitability of some companies in the pharmaceuticals industry may be dependent on a relatively limited number of products. In addition, their products can become obsolete due to industry innovation, changes in technologies or other market developments. Many new products in the pharmaceuticals industry are subject to government approvals, regulation and reimbursement rates. The process of obtaining government approvals may be long and costly. Many companies in the pharmaceuticals industry are heavily dependent on patent protection. The expiration of patents may adversely affect the profitability of these companies. Companies in the pharmaceutical industry may be subject to extensive litigation based on product liability and similar claims.

Privatization Risk. Some countries in which the Fund invests have begun a process of privatizing certain entities and industries. In some instances, investors in newly privatized entities have suffered losses due to the inability of the newly privatized entities to adjust quickly to a competitive environment or changing regulatory and legal standards or, in some cases, due to re-nationalization of such privatized entities. There is no assurance that such losses will not recur.

Reliance on Trading Partners Risk. The economies of the ACWI ex US health care sector countries are dependent on each other and on the United States as key trading partners. Reduction in spending on the products and services of the ACWI ex US health care sector countries by any of their key trading partners, institution of tariffs or other trade barriers or a slowdown in the economies of any of their key trading partners may cause an adverse impact on the economies of the ACWI ex US health care sector countries.

U.S. Trading Partners Risk. The United States is a significant, and in some cases the most significant, trading partner of or foreign investor in certain ACWI ex US health care sector countries and the economies of these countries may be particularly affected by changes in the U.S. economy. Decreasing U.S. imports, new trade regulations, changes in the U.S. dollar exchange rate or a recession in the United States may have a material adverse effect on the economies of ACWI ex US health care sector countries.

Risk of Investing in Switzerland. Investment in Swiss issuers may subject the Fund to legal, regulatory, political, currency, security, and economic risk specific to Switzerland. Among other things, Switzerland’s economy is heavily dependent on trading relationships with certain key trading partners, including the United States, United Kingdom, France and Germany. Future changes in the price or the demand for Swiss products or services by the United States, United Kingdom, France and Germany or changes in these countries’ economies, trade regulations or currency exchange rates could adversely impact the Swiss economy and the issuers to which the Fund has exposure. Switzerland’s economy relies heavily on the banking sector. Recently, allegations have surfaced that certain Swiss banking institutions marketed and sold

offshore tax evasion services to U.S. citizens. Future litigation or settlements arising from these offshore tax evasion services may have a negative impact on certain companies to which the Fund has exposure. Due to the lack of natural resources, Switzerland is dependent upon imports for raw materials. As a result, any drastic price fluctuations in the price of certain raw materials will likely have a significant impact on the Swiss economy.

Risk of Investing in the United Kingdom. Investment in British issuers may subject the Fund to regulatory, political, currency, security, and economic risk specific to the United Kingdom. The British economy relies heavily on export of financial services to the United States and other European countries. A prolonged slowdown in the financial services sector will have a negative impact on the British economy. In the past, the United Kingdom has been a target of terrorism. Acts of terrorism in the United Kingdom or against British interests abroad may cause uncertainty in the British financial markets and adversely affect the performance of the issuers to which the Fund has exposure. The British economy, along with the United States and certain other European economies, experienced a significant economic slowdown during the recent financial crisis.

Securities Lending Risk. The Fund may engage in securities lending. Securities lending involves the risk that the Fund may lose money because the borrower of the Fund’s loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for the loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Security Risk. Some geographic areas in which the Fund invests have experienced acts of terrorism or strained international relations due to territorial disputes, historical animosities or other defense concerns. These situations may cause uncertainty in the markets of these geographic areas and may adversely affect the performance of their economies.

Small-Capitalization Companies Risk. Many of the companies in which the Fund invests are considered small-capitalization companies. Stock prices of small-capitalization companies may be more volatile than those of larger companies and, therefore, the Fund’s share price may be more volatile than those of funds that invest a larger percentage of their assets in stocks issued by mid- or large-capitalization companies. Stock prices of small-capitalization companies are generally more vulnerable than those of mid- or large-capitalization companies to adverse business and economic developments. Securities of small-capitalization companies may be thinly traded, making it difficult for the Fund to buy and sell them. In addition, small-capitalization companies are typically less financially stable than larger, more established companies and may depend on a small number of essential personnel, making them more vulnerable to loss of personnel. Small-capitalization companies also normally have less diverse product lines than mid- or large-capitalization companies and are more susceptible to adverse developments concerning their products.

Structural Risk. Certain political, economic, legal and currency risks have contributed to a high degree of price volatility in the equity markets of the ACWI ex US health care sector countries and could adversely affect investments in the Fund:

Political and Social Risk. Disparities of wealth, the pace and success of democratization and ethnic, religious and racial disaffection, among other factors, have led to social unrest, violence and labor unrest in some ACWI ex US health care sector countries. Unanticipated or sudden political or social developments may result in sudden and significant investment losses.

Economic Risk. Some ACWI ex US health care sector countries may experience economic instability, including instability resulting from substantial rates of inflation or significant devaluations of their currency, or economic recessions causing a negative effect on the economies and securities markets of their economies. Some of these countries may also impose restrictions on the exchange or export of currency or adverse currency exchange rates and may be characterized by a lack of available currency hedging instruments.

Expropriation and/or Nationalization Risk. Investments in certain ACWI ex US health care sector countries may be subject to loss due to expropriation or nationalization of assets and property or the imposition of restrictions on foreign investments and repatriation of capital.

Large Government Debt Risk. Chronic structural public sector deficits in some ACWI ex US health care sector countries may adversely impact investments in the Fund.

Tracking Error Risk. Imperfect correlation between the Fund’s portfolio securities and those in the Underlying Index, rounding of prices, changes to the Underlying Index and regulatory requirements may cause tracking error, which is the divergence of the Fund’s performance from that of the Underlying Index. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Underlying Index does not. Because the Fund employs a representative sampling strategy, the Fund may experience tracking error to a greater extent than a fund that seeks to replicate an index.

Valuation Risk. Because non-U.S. exchanges may be open on days when the Fund does not price its shares, the value of the securities in the Fund’s portfolio may change on days when shareholders will not be able to purchase or sell the Fund’s shares. In addition, for purposes of calculating the Fund’s NAV, the value of assets denominated in non-U.S. currencies is converted into U.S. dollars using exchange rates deemed appropriate by BFA. This conversion may result in a difference between the prices used to calculate the Fund’s NAV and the prices used by the Underlying Index, which, in turn, could result in a difference between the Fund’s performance and the performance of the Underlying Index.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

Asian Economic Risk. Certain Asian economies have experienced over-extension of credit, currency devaluations and restrictions, high unemployment, high inflation, decreased exports and economic recessions. Economic events in any one Asian country may have a significant economic effect on the entire Asian region, as well as on major trading partners outside Asia, and any adverse event in the Asian markets may have a significant adverse effect on some or all of the ACWI ex US health care sector countries.

Portfolio Holdings Information

A description of the Trust’s policies and procedures with respect to the disclosure of the Fund’s portfolio securities is available in the Fund’s Statement of Additional Information (“SAI”). The top holdings of the Fund can be found at www.iShares.com. Fund fact sheets provide information regarding the Fund’s top holdings and may be requested by calling 1-800-iShares (1-800-474-2737).

Management

Investment Adviser. As investment adviser, BFA has overall responsibility for the general management and administration of the Trust. BFA provides an investment program for the Fund and manages the investment of the Fund’s assets. In managing the Fund, BFA may draw upon the research and expertise of its asset management affiliates with respect to certain portfolio securities. In seeking to achieve the Fund’s investment objective, BFA uses teams of portfolio managers, investment strategists and other investment specialists. This team approach brings together many disciplines and leverages BFA’s extensive resources.

Pursuant to the Investment Advisory Agreement between BFA and the Trust (entered into on behalf of the Fund), BFA is responsible for substantially all expenses of the Fund, except interest expenses, taxes, brokerage expenses, future distribution fees or expenses and extraordinary expenses.

For its investment advisory services to the Fund, BFA is entitled to receive a management fee from the Fund based on a percentage of the Fund’s average daily net assets, at the annual rate of 0.48%.

BFA is located at 400 Howard Street, San Francisco, CA 94105. It is a wholly owned subsidiary of BTC, which in turn is indirectly wholly-owned by BlackRock, Inc. (“BlackRock”). As of September 30, 2011, BTC and its affiliates, including BFA and BlackRock, provided investment advisory services for assets in excess of $3.35 trillion. BFA, BTC, BlackRock Execution Services, BlackRock and their affiliates deal, trade and invest for their own accounts in the types of securities in which the Fund may also invest.

A discussion regarding the basis for the Trust’s Board of Trustees’ (the “Board”) approval of the Investment Advisory Agreement with BFA is available in the Fund’s annual report for the period ended July 31.

Portfolio Managers. Rene Casis, Diane Hsiung and Greg Savage are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager is responsible for various functions related to portfolio management, including, but not

limited to, investing cash inflows, coordinating with members of his or her portfolio management team to focus on certain asset classes, implementing investment strategy, researching and reviewing investment strategy and overseeing members of his or her portfolio management team that have more limited responsibilities.

The Fund’s SAI provides additional information about the Portfolio Managers’ compensation, other accounts managed by the Portfolio Managers and the Portfolio Managers’ ownership (if any) of shares in the Fund.

Administrator, Custodian and Transfer Agent. State Street Bank and Trust Company (“State Street”) is the administrator, custodian and transfer agent for the Fund.

Conflicts of Interest. BFA wants you to know that there are certain entities with which BFA has relationships that may give rise to conflicts of interest, or the appearance of conflicts of interest. These entities include the following: BFA’s affiliates (including BlackRock and The PNC Financial Services Group, Inc., and each of their affiliates, directors, partners, trustees, managing members, officers and employees (collectively, the “Affiliates”)) and BlackRock’s significant shareholder, Barclays Bank PLC and its affiliates, including Barclays PLC (each, an “Entity” and together, the “Entities”).

The activities of BFA, the Affiliates and the Entities in the management of, or their interest in, their own accounts and other accounts they manage, may present conflicts of interest that could disadvantage the Fund and the shareholders. BFA and its Affiliates or the Entities provide investment management services to other funds and discretionary managed accounts that may follow an investment program similar to that of the Fund. BFA, its Affiliates and the Entities are involved worldwide with a broad spectrum of financial services and asset management activities and may engage in the ordinary course of business in activities in which their interests or the interests of their clients may conflict with those of the Fund. BFA, one or more of the Affiliates or the Entities acts, or may act, as an investor, investment banker, research provider, investment manager, financier, underwriter, advisor, market maker, trader, prime broker, lender, agent or principal, and have other direct and indirect interests, in securities, currencies and other instruments in which the Fund may directly or indirectly invest. Thus, it is likely that the Fund will have multiple business relationships with and will invest in, engage in transactions with, make voting decisions with respect

to, or obtain services from, entities for which BFA, an Affiliate or an Entity performs or seeks to perform investment banking or other services.

BFA or one or more Affiliates or Entities may engage in proprietary trading and advise accounts and funds that have investment objectives similar to those of the Fund and/or that engage in and compete for transactions in the same types of securities, currencies and other instruments as the Fund, including in securities issued by other open-end and closed-end investment management companies, including investment companies that are affiliated with the Fund and BFA, to the extent permitted under the Investment Company Act of 1940, as amended (the “1940 Act”). The trading activities of BFA, these Affiliates and Entities are carried out without reference to positions held directly or indirectly by the Fund and may result in BFA, an Affiliate or an Entity having positions that are adverse to those of the Fund.

No Affiliate or Entity is under any obligation to share any investment opportunity, idea or strategy with the Fund. As a result, an Affiliate or an Entity may compete with the Fund for appropriate investment opportunities. As a result of this and several other factors, the results of the Fund’s investment activities may differ from those of an Affiliate or an Entity and of other accounts managed by an Affiliate or an Entity, and it is possible that the Fund could sustain losses during periods in which one or more Affiliates or Entities and other accounts achieve profits on their trading for proprietary or other accounts. The opposite result is also possible.

The Fund may, from time to time, enter into transactions in which BFA or an Affiliate’s or an Entity’s clients have an interest adverse to the Fund. Furthermore, transactions undertaken by Affiliate-advised clients may adversely impact the Fund. Transactions by one or more Affiliate- or Entity-advised clients or BFA may have the effect of diluting or otherwise disadvantaging the values, prices or investment strategies of the Fund.

An Entity may maintain securities indices as part of the product offerings. Index-based funds seek to track the performance of securities indices and may use the name of the index in the fund name. Index providers, including the Entities, may be paid licensing fees for use of their indices or index names. Entities will not be obligated to license their indices to BFA and its Affiliates, and BFA and its Affiliates will not be assured that the terms of any index licensing agreement with the Entities will be as favorable as those terms offered to other index licensees.

The Fund’s activities may be limited because of regulatory restrictions applicable to one or more Affiliates or Entities, and/or their internal policies designed to comply with such restrictions. In addition, the Fund may invest in securities of companies with which an Affiliate or an Entity has or is trying to develop investment banking relationships or in which an Affiliate or an Entity has significant debt or equity investments. The Fund also may invest in securities of companies for which an Affiliate or an Entity provides or may some day provide research coverage. An Affiliate or an Entity may have business relationships with and purchase or distribute or sell services or products from or to distributors, consultants or others who recommend the Fund or who engage in transactions with or for the Fund, and may receive compensation for such services. The Fund may also make brokerage and other payments to Affiliates or Entities in connection with the Fund’s portfolio investment transactions.

Pursuant to a securities lending program approved by the Board, the Fund has retained an Affiliate of BFA to serve as the securities lending agent for the Fund to the extent that the Fund participates in the securities lending program. For these services, the lending agent may receive a fee from the Fund, including a fee based on the returns earned on the Fund’s investment of the cash received as collateral for any loaned securities. In addition, one or more Affiliates may be among the entities to which the Fund may lend its portfolio securities under the securities lending program.

The activities of BFA, the Affiliates or Entities may give rise to other conflicts of interest that could disadvantage the Fund and the shareholders. BFA has adopted policies and procedures designed to address these potential conflicts of interest. See the Fund’s SAI for further information.

Shareholder Information

Additional shareholder information, including how to buy and sell shares of the Fund, is available free of charge by calling toll-free: 1-800-iShares (1-800-474-2737) or visiting our website at www.iShares.com.

Buying and Selling Shares. Shares of the Fund may be acquired or redeemed directly from the Fund only in Creation Units or multiples thereof, as discussed in the Creations and Redemptions section of this Prospectus. Only an Authorized Participant (as defined in the Creations and Redemptions section) may engage in creation or redemption transactions directly with the Fund. Once created, shares of the Fund generally trade in the secondary market in amounts less than a Creation Unit.

Shares of the Fund are listed on a national securities exchange for trading during the trading day. Shares can be bought and sold throughout the trading day like shares of other publicly-traded companies. The Trust does not impose any minimum investment for shares of the Fund purchased on an exchange. The Fund’s shares trade under the trading symbol “AXHE.”

Buying or selling Fund shares on an exchange involves two types of costs that may apply to all securities transactions. When buying or selling shares of the Fund through a broker, you will likely incur a brokerage commission or other charges determined by your broker. The commission is frequently a fixed amount and may be a significant proportional cost for investors seeking to buy or sell small amounts of shares. In addition, you may incur the cost of the “spread” – that is, any difference between the bid price and the ask price. The spread varies over time for shares of the Fund based on the trading volume and market liquidity, and is generally lower if the Fund has a lot of trading volume and market liquidity, and higher if the Fund has little trading volume and market liquidity.

The Board has adopted a policy of not monitoring for frequent purchases and redemptions of Fund shares (“frequent trading”) that appear to attempt to take advantage of a potential arbitrage opportunity presented by a lag between a change in the value of the Fund’s portfolio securities after the close of the primary markets for the Fund’s portfolio securities and the reflection of that change in the Fund’s NAV (“market timing”), because the Fund generally sells and redeems its shares directly through transactions that are in-kind and/or for cash, subject to the conditions

described below under Creations and Redemptions. The Board has not adopted a policy of monitoring for other frequent trading activity because shares of the Fund are listed for trading on a national securities exchange.

The national securities exchange on which the Fund’s shares are listed is open for trading Monday through Friday and is closed on weekends and the following holidays: New Year’s Day, Martin Luther King, Jr. Day, Presidents’ Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day. The Fund’s primary listing exchange is NYSE Arca.

Section 12(d)(1) of the 1940 Act restricts investments by investment companies in the securities of other investment companies. Registered investment companies are permitted to invest in the Fund beyond the limits set forth in Section 12(d)(1), subject to certain terms and conditions set forth in SEC rules or in an SEC exemptive order issued to the Trust. In order for a registered investment company to invest in shares of the Fund beyond the limitations of Section 12(d)(1) pursuant to the exemptive relief obtained by the Trust, the registered investment company must enter into an agreement with the Trust.

Book Entry. Shares of the Fund are held in book-entry form, which means that no stock certificates are issued. The Depository Trust Company (“DTC”) or its nominee is the record owner of all outstanding shares of the Fund and is recognized as the owner of all shares for all purposes.

Investors owning shares of the Fund are beneficial owners as shown on the records of DTC or its participants. DTC serves as the securities depository for shares of the Fund. DTC participants include securities brokers and dealers, banks, trust companies, clearing corporations and other institutions that directly or indirectly maintain a custodial relationship with DTC. As a beneficial owner of shares, you are not entitled to receive physical delivery of stock certificates or to have shares registered in your name, and you are not considered a registered owner of shares. Therefore, to exercise any right as an owner of shares, you must rely upon the procedures of DTC and its participants. These procedures are the same as those that apply to any other securities that you hold in book-entry or “street name” form.

Share Prices. The trading prices of the Fund’s shares in the secondary market generally differ from the Fund’s daily NAV and are affected by market forces such as supply and demand, economic conditions and other factors. Information regarding the intraday value of shares of the Fund, also known as the “indicative optimized portfolio value” (“IOPV”), is disseminated every 15 seconds throughout the trading day by the national securities exchange on which the Fund’s shares are listed or by market data vendors or other information providers. The IOPV is based on the current market value of the securities and/or cash required to be deposited in exchange for a Creation Unit. The IOPV does not necessarily reflect the precise composition of the current portfolio of securities held by the Fund at a particular point in time or the best possible valuation of the current portfolio. Therefore, the IOPV should not be viewed as a “real-time” update of the Fund’s NAV, which is computed only once a day. The IOPV is generally determined by using both current market quotations and/or price quotations obtained from broker-dealers that may trade in the portfolio securities held by the Fund. The quotations of certain Fund holdings may not be updated during U.S. trading hours if

such holdings do not trade in the United States. The Fund is not involved in, or responsible for, the calculation or dissemination of the IOPV and makes no representation or warranty as to its accuracy.

Determination of Net Asset Value. The NAV of the Fund normally is determined once daily Monday through Friday, generally as of the regularly scheduled close of business of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m., Eastern time) on each day that the NYSE is open for trading, based on prices at the time of closing provided that (a) any Fund assets or liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers (as detailed below) and (b) U.S. fixed income assets may be valued as of the announced closing time for trading in fixed income instruments in a particular market or exchange. The NAV of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets held by the Fund, and its liabilities, are determined pursuant to valuation policies and procedures approved by the Board. The Fund’s assets and liabilities are valued primarily on the basis of market quotations.

Equity investments are valued at market value, which is generally determined using the last reported official closing price or last trading price on the exchange or market on which the security is primarily traded at the time of valuation.

The Fund invests in foreign securities. Foreign currency exchange rates are generally determined as of 4:00 p.m., London time. Foreign securities owned by the Fund may trade on weekends or other days when the Fund does not price its shares. As a result, the Fund’s NAV may change on days when Authorized Participants will not be able to purchase or redeem Fund shares.

Generally, trading in foreign securities, U.S. government securities, money market instruments and certain fixed-income securities is substantially completed each day at various times prior to the close of business on the NYSE. The values of such securities used in computing the NAV of the Fund are determined as of such times.

When market quotations are not readily available or are believed by BFA to be unreliable, the Fund’s investments are valued at fair value. Fair value determinations are made by BFA in accordance with policies and procedures approved by the Fund’s Board. BFA may conclude that a market quotation is not readily available or is unreliable if a security or other asset or liability does not have a price source due to its lack of liquidity, if a market quotation differs significantly from recent price quotations or otherwise no longer appears to reflect fair value, where the security or other asset or liability is thinly traded, or where there is a significant event subsequent to the most recent market quotation. A “significant event” is an event that, in the judgment of BFA, is likely to cause a material change to the closing market price of the asset or liability held by the Fund. Foreign securities whose values are affected by volatility that occurs in U.S. markets on a trading day after the close of foreign securities markets may be fair valued.

Fair value represents a good faith approximation of the value of an asset or liability. The fair value of an asset or liability held by the Fund is the amount the Fund might reasonably expect to receive from the current sale of that asset or the cost to extinguish that liability in an arm’s-length transaction. Valuing the Fund’s investments using fair value pricing will result in prices that may differ from current market valuations and that may not be the price at which those investments could have been sold during the period in which the particular fair values were used. Use of fair value prices and certain current market valuations could result in a difference between the prices used to calculate the Fund’s NAV and the prices used by the Underlying Index, which, in turn, could result in a difference between the Fund’s performance and the performance of the Underlying Index.

The value of assets or liabilities denominated in non-U.S. currencies will be converted into U.S. dollars using exchange rates deemed appropriate by BFA as investment adviser. Use of a rate different from the rate used by the Index Provider may adversely affect the Fund’s ability to track the Underlying Index.

Dividends and Distributions

General Policies. Dividends from net investment income, if any, generally are declared and paid semi-annually by the Fund. Distributions of net realized securities gains, if any, generally are declared and paid once a year, but the Trust may make distributions on a more frequent basis for the Fund. The Trust reserves the right to declare special distributions if, in its reasonable discretion, such action is necessary or advisable to preserve its status as a regulated investment company (“RIC”) or to avoid imposition of income or excise taxes on undistributed income or realized gains.

Dividends and other distributions on shares of the Fund are distributed on a pro rata basis to beneficial owners of such shares. Dividend payments are made through DTC participants and indirect participants to beneficial owners then of record with proceeds received from the Fund.

Dividend Reinvestment Service. No dividend reinvestment service is provided by the Trust. Broker-dealers may make available the DTC book-entry Dividend Reinvestment Service for use by beneficial owners of the Fund for reinvestment of their dividend distributions. Beneficial owners should contact their broker to determine the availability and costs of the service and the details of participation therein. Brokers may require beneficial owners to adhere to specific procedures and timetables. If this service is available and used, dividend distributions of both income and realized gains will be automatically reinvested in additional whole shares of the Fund purchased in the secondary market.

Taxes. As with any investment, you should consider how your investment in shares of the Fund will be taxed. The tax information in this Prospectus is provided as general information, based on current law. You should consult your own tax professional about the tax consequences of an investment in shares of the Fund.

Unless your investment in Fund shares is made through a tax-exempt entity or tax-deferred retirement account, such as an IRA, you need to be aware of the possible tax consequences when the Fund makes distributions or you sell Fund shares.

Taxes on Distributions. Distributions from the Fund’s net investment income (other than qualified dividend income), including distributions of income from securities lending and distributions out of the Fund’s net short-term capital gains, if any, are taxable to you as ordinary income. Distributions by the Fund of net long-term capital gains in excess of net short-term capital losses (capital gain dividends) are taxable to you as long-term capital gains, generally at a 15% tax rate (0% at certain income levels), regardless of how long you have held the Fund’s shares. Distributions by the Fund that qualify as qualified dividend income are taxable to you at long-term capital gain rates for taxable years beginning on or before December 31, 2012. The 15% and 0% tax rates expire for taxable years beginning after December 31, 2012. Maximum long-term capital gain income tax rates are scheduled to rise to 20% in 2013. Beginning in 2013, a 3.8% U.S. federal Medicare contribution tax will be imposed on “net investment income,” including interest, dividends, and capital gains, of U.S. individuals with income exceeding $200,000 (or $250,000 if married and filing jointly), and of estates and trusts.

Dividends will be qualified dividend income to you if they are attributable to qualified dividend income received by the Fund. Generally, qualified dividend income includes dividend income from taxable U.S. corporations and qualified non-U.S. corporations, provided that the Fund satisfies certain holding period requirements in respect of the stock of such corporations and has not hedged its position in the stock in certain ways. Substitute dividends received by the Fund with respect to dividends paid on securities lent out will not be qualified dividend income. For this purpose, a qualified non-U.S. corporation means any non-U.S. corporation that is eligible for benefits under a comprehensive income tax treaty with the United States, which includes an exchange of information program or if the stock with respect to which the dividend was paid is readily tradable on an established United States securities market. The term excludes a corporation that is a passive foreign investment company.

Dividends received by the Fund from a real estate investment trust (“REIT”) or another RIC generally are qualified dividend income only to the extent the dividend distributions are made out of qualified dividend income received by such REIT or RIC. It is expected that dividends received by the Fund from a REIT and distributed to a shareholder generally will be taxable to the shareholder as ordinary income.

For a dividend to be treated as qualified dividend income, the dividend must be received with respect to a share of stock held without being hedged by the Fund, and with respect to a share of the Fund held without being hedged by you, for 61 days during the 121-day period beginning at the date which is 60 days before the date on which such share becomes ex-dividend with respect to such dividend or, in the case of certain preferred stock, 91 days during the 181-day period beginning 90 days before such date.

If your Fund shares are loaned out pursuant to a securities lending arrangement, you may lose the ability to use foreign tax credits passed through by the Fund or to treat Fund dividends paid while the shares are held by the borrower as qualified dividend income.

In general, your distributions are subject to U.S. federal income tax for the year when they are paid. Certain distributions paid in January, however, may be treated as paid on December 31 of the prior year.

If the Fund’s distributions exceed current and accumulated earnings and profits, all or a portion of the distributions made in the taxable year may be recharacterized as a return of capital to shareholders. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and result in a higher capital gain or lower capital loss when those shares on which the distribution was received are sold. Once a shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain, if the shareholder holds shares of the Fund as capital assets.

If you are neither a resident nor a citizen of the United States or if you are a non-U.S. entity, the Fund’s ordinary income dividends (which include distributions of net short-term capital gains) will generally be subject to a 30% U.S. withholding tax, unless a lower treaty rate applies, provided that withholding tax will generally not apply to any gain or income realized by a non-U.S. shareholder in respect of any distributions of long-term capital gains or upon the sale or other disposition of shares of the Fund.

A 30% withholding tax will be imposed on dividends paid after December 31, 2013, and redemption proceeds paid after December 31, 2014, to (i) foreign financial institutions including non-U.S. investment funds unless they agree to collect and disclose to the Internal Revenue Service (“IRS”) information regarding their direct and indirect U.S. account holders and (ii) certain other foreign entities, unless they certify certain information regarding their direct and indirect U.S. owners. To avoid withholding, foreign financial institutions will need to enter into agreements with the IRS that state that they will provide the IRS information, including the name, address and taxpayer identification number of direct and indirect U.S. account holders, comply with due diligence procedures with respect to the identification of U.S. accounts, report to the IRS certain information with respect to U.S. accounts maintained, agree to withhold tax on certain payments made to non-compliant foreign financial institutions or to account holders who fail to provide the required information, and determine certain other information as to their account holders. Other foreign entities will need to provide the name, address, and taxpayer identification number of each substantial U.S. owner or certifications of no substantial U.S. ownership unless certain exceptions apply.

Dividends, interest and capital gains earned by the Fund with respect to non-U.S. securities may give rise to withholding and other taxes imposed by non-U.S. countries. Tax conventions between certain countries and the United States may reduce or eliminate such taxes. If more than 50% of the total assets of the Fund at the close of a year consists of non-U.S. stocks or securities, the Fund may “pass through” to you certain non-U.S. income taxes (including withholding taxes) paid by the Fund. This means that you would be considered to have received as an additional dividend your share of such non-U.S. taxes, but you may be entitled to either a corresponding tax deduction in calculating your taxable income, or, subject to certain limitations, a credit in calculating your U.S. federal income tax.

For purposes of foreign tax credits for U.S. shareholders of the Fund, foreign capital gains taxes may not produce associated foreign source income, thereby limiting a U.S. person’s ability to use such credits.

If you are a resident or a citizen of the United States, by law, back-up withholding will apply to your distributions and proceeds if you have not provided a taxpayer identification number or social security number and made other required certifications.

Taxes When Shares are Sold. Currently, any capital gain or loss realized upon a sale of Fund shares is generally treated as a long-term gain or loss if the shares have been held for more than one year. Any capital gain or loss realized upon a sale of Fund shares held for one year or less is generally treated as short-term gain or loss, except that any capital loss on the sale of shares held for six months or less is treated as long-term capital loss to the extent that capital gain dividends were paid with respect to such shares. Beginning in 2013, any such capital gains, including from sales of Fund shares or from capital gain dividends, will be included in “net investment income” for purposes of the 3.8% U.S. federal Medicare contribution tax mentioned above.

The foregoing discussion summarizes some of the consequences under current U.S. federal tax law of an investment in the Fund. It is not a substitute for personal tax advice. You may also be subject to state and local taxation on Fund distributions and sales of shares. Consult your personal tax adviser about the potential tax consequences of an investment in shares of the Fund under all applicable tax laws.

Creations and Redemptions. Prior to trading in the secondary market, shares of the Fund are “created” at NAV by market makers, large investors and institutions only in block-size Creation Units of 50,000 shares or multiples thereof. Each “creator” or “Authorized Participant” enters into an authorized participant agreement with the Fund’s distributor, SEI Investments Distribution Co. (the “Distributor”). Only an Authorized Participant may create or redeem Creation Units directly with the Fund. A creation transaction, which is subject to acceptance by the transfer agent, generally takes place when an Authorized Participant deposits into the Fund a designated portfolio of securities and a specified amount of cash approximating the holdings of the Fund in exchange for a specified number of Creation Units. To the extent practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund.

Similarly, shares can be redeemed only in Creation Units, generally for a designated portfolio of securities and a specified amount of cash held by the Fund (“Fund Securities”). Except when aggregated in Creation Units, shares are not redeemable by the Fund. The prices at which creations and redemptions occur are based on the next calculation of NAV after an order is received in a form described in the authorized participant agreement.

The Fund intends to comply with the U.S. federal securities laws in accepting securities for deposit and satisfying redemptions with redemption securities by, among other means, assuring that any securities accepted for deposit and any securities used to satisfy redemption requests will be sold in transactions that would be exempt from registration under the Securities Act of 1933, as amended (the “1933 Act”). Further, an Authorized Participant that is not a “qualified institutional buyer,” as such term is

defined under Rule 144A of the 1933 Act, will not be able to receive Fund Securities that are restricted securities eligible for resale under Rule 144A.

Creations and redemptions must be made through a firm that is either a member of the Continuous Net Settlement System of the National Securities Clearing Corporation or a DTC participant and has executed an agreement with the Distributor with respect to creations and redemptions of Creation Unit aggregations. Information about the procedures regarding creation and redemption of Creation Units (including the cut-off times for receipt of creation and redemption orders) is included in the Fund’s SAI.

Because new shares may be created and issued on an ongoing basis, at any point during the life of the Fund a “distribution,” as such term is used in the 1933 Act, may be occurring. Broker-dealers and other persons are cautioned that some activities on their part may, depending on the circumstances, result in their being deemed participants in a distribution in a manner that could render them statutory underwriters and subject to the prospectus delivery and liability provisions of the 1933 Act. Any determination of whether one is an underwriter must take into account all the relevant facts and circumstances of each particular case.

Broker-dealers should also note that dealers who are not “underwriters” but are participating in a distribution (as contrasted to ordinary secondary transactions), and thus dealing with shares that are part of an “unsold allotment” within the meaning of Section 4(3)(C) of the 1933 Act, would be unable to take advantage of the prospectus delivery exemption provided by Section 4(3) of the 1933 Act. For delivery of prospectuses to exchange members, the prospectus delivery mechanism of Rule 153 under the 1933 Act is available only with respect to transactions on a national securities exchange.

Costs Associated with Creations and Redemptions. Authorized Participants are charged standard creation and redemption transaction fees to offset transfer and other transaction costs associated with the issuance and redemption of Creation Units. The standard creation and redemption transaction fees are set forth in the table below. The standard creation transaction fee is charged to the Authorized Participant on the day such Authorized Participant creates a Creation Unit, and is the same regardless of the number of Creation Units purchased by the Authorized Participant on the applicable business day. Similarly, the standard redemption transaction fee is charged to the Authorized Participant on the day such Authorized Participant redeems a Creation Unit, and is the same regardless of the number of Creation Units redeemed by the Authorized Participant on the applicable business day. Creations and redemptions for cash (when cash creations and redemptions (in whole or in part) are available or specified) are also subject to an additional charge (up to the maximum amounts shown in the table below). This charge is intended to compensate for brokerage, tax, foreign exchange, execution, market impact and other costs and expenses related to cash transactions. Investors who use the services of a broker or other financial intermediary may pay fees for such services.

The following table shows, as of September 30, 2011, the approximate value of one Creation Unit, standard fees and maximum additional charges for creations and redemptions (as described above):

Householding. Householding is an option available to certain Fund investors. Householding is a method of delivery, based on the preference of the individual investor, in which a single copy of certain shareholder documents can be delivered to investors who share the same address, even if their accounts are registered under different names. Please contact your broker-dealer if you are interested in enrolling in householding and receiving a single copy of prospectuses and other shareholder documents, or if you are currently enrolled in householding and wish to change your householding status.

Distribution

The Distributor distributes Creation Units for the Fund on an agency basis. The Distributor does not maintain a secondary market in shares of the Fund. The Distributor has no role in determining the policies of the Fund or the securities that are purchased or sold by the Fund. The Distributor’s principal address is One Freedom Valley Drive, Oaks, PA 19456.

In addition, BFA or its Affiliates make payments to broker-dealers, banks or other financial intermediaries (together, “intermediaries”) related to marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems, or their making shares of the Fund and certain other iShares funds available to their customers. Such payments, which may be significant to the intermediary, are not made by the Fund. Rather, such payments are made by BFA or its Affiliates from their own resources, which come directly or indirectly in part from fees paid by the iShares funds complex. Payments of this type are sometimes referred to as revenue-sharing payments. A financial intermediary may make decisions about which investment options it recommends or makes available, or the level of services provided, to its customers based on the revenue-sharing payments it is eligible to receive. Therefore, such payments to an intermediary create conflicts of interest between the intermediary and its customers and may cause the intermediary to recommend the Fund or other iShares funds over another investment. More information regarding these payments is contained in the Fund’s SAI. Please contact your salesperson or other investment professional for more information regarding any such payments his or her firm may receive from BFA or its Affiliates.

Financial Highlights

The financial highlights table is intended to help investors understand the Fund’s financial performance since inception. Certain information reflects financial results for a single share of the Fund. The total returns in the table represent the rate that an investor would have earned (or lost) on an investment in the Fund, assuming reinvestment of all dividends and distributions. This information has been audited by PricewaterhouseCoopers LLP, whose report is included, along with the Fund’s financial statements, in the Fund’s Annual Report (available upon request).

Supplemental Information

I. Premium/Discount Information

The table that follows presents information about the differences between the daily market price on secondary markets for shares of the Fund and the Fund’s NAV. NAV is the price at which the Fund issues and redeems shares. It is calculated in accordance with the standard formula for valuing mutual fund shares. The price used to calculate market returns (“Market Price”) of the Fund generally is determined using the midpoint between the highest bid and the lowest offer on the primary securities exchange on which shares of the Fund are listed for trading, as of the time that the Fund’s NAV is calculated. The Fund’s Market Price may be at, above or below its NAV. The NAV of the Fund will fluctuate with changes in the value of its portfolio holdings. The Market Price of the Fund will fluctuate in accordance with changes in its NAV, as well as market supply and demand.

Premiums or discounts are the differences (expressed as a percentage) between the NAV and Market Price of the Fund on a given day, generally at the time the NAV is calculated. A premium is the amount that the Fund is trading above the reported NAV, expressed as a percentage of the NAV. A discount is the amount that the Fund is trading below the reported NAV, expressed as a percentage of the NAV.

The following information shows the frequency of distributions of premiums and discounts for the Fund from October 1, 2010 through September 30, 2011.

Each line in the table shows the number of trading days in which the Fund traded within the premium/discount range indicated. The number of trading days in each premium/discount range is also shown as a percentage of the total number of trading days in the period covered by the table. All data presented here represents past performance, which cannot be used to predict future results.

   253 100.00%

II. Total Return Information

The table that follows presents information about the total returns of the Fund and the Underlying Index as of the fiscal year ended July 31, 2011.

“Average Annual Total Returns” represent the average annual change in value of an investment over the periods indicated. “Cumulative Total Returns” represent the total change in value of an investment over the period indicated.

The Fund’s NAV is the value of one share of the Fund as calculated in accordance with the standard formula for valuing mutual fund shares. The NAV return is based on the NAV of the Fund and the market return is based on the Market Price of the Fund. Market Price is determined by using the midpoint between the highest bid and the lowest offer on the primary stock exchange on which shares of the Fund are listed for trading, as of the time that the Fund’s NAV is calculated. Since shares of the Fund did not trade in the secondary market until after the Fund’s inception, for the period from inception to the first day of secondary market trading in shares of the Fund, the NAV of the Fund is used as a proxy for the Market Price to calculate market returns. Market and NAV returns assume that dividends and capital gain distributions have been reinvested in the Fund at Market Price and NAV, respectively.

An index is a statistical composite that tracks a specified financial market or sector. Unlike the Fund, the Underlying Index does not actually hold a portfolio of securities and therefore does not incur the expenses incurred by the Fund. These expenses negatively impact the performance of the Fund. Also, market returns do not include brokerage commissions that may be payable on secondary market transactions. If brokerage commissions were included, market returns would be lower. The returns shown in the following table do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption or sale of Fund shares. The investment return and principal value of shares of the Fund will vary with changes in market conditions. Shares of the Fund may be worth more or less than their original cost when they are redeemed or sold in the market. The Fund’s past performance is no guarantee of future results.

Fund Overview

iSHARES® MSCI ACWI ex US INDEX FUND

Ticker: ACWX Stock Exchange: NASDAQ

Investment Objective

The iShares MSCI ACWI ex US Index Fund (the “Fund”) seeks investment results that correspond generally to the price and yield performance, before fees and expenses, of the MSCI All Country World Index ex USA (the “Underlying Index”).

Fees and Expenses

The following table describes the fees and expenses that you will incur if you own shares of the Fund. The investment advisory agreement between iShares Trust (the “Trust”) and BlackRock Fund Advisors (“BFA”) (the “Investment Advisory Agreement”) provides that BFA will pay all operating expenses of the Fund, except interest expenses, taxes, brokerage expenses, future distribution fees or expenses, and extraordinary expenses.

You may also incur usual and customary brokerage commissions when buying or selling shares of the Fund, which are not reflected in the example that follows:

Annual Fund Operating Expenses

percentage of the value of your investments)

Operating
Expenses
0.34% None None 0.34%

Example. This Example is intended to help you compare the cost of owning shares of the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

3 Years
5 Years
10 Years

Portfolio Turnover. The Fund may pay transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 7% of the average value of its portfolio.

Principal Investment Strategies

The Underlying Index is a free float-adjusted market capitalization index designed to measure the combined equity market performance of developed and emerging markets countries, excluding the United States. As of September 30, 2011, the Underlying Index consisted of companies in the following countries or regions: Australia, Austria, Belgium, Brazil, Canada, Chile, China, Colombia, the Czech Republic, Denmark, Egypt, Finland, France, Germany, Greece, Hong Kong, Hungary, India, Indonesia, Ireland, Israel, Italy, Japan, Malaysia, Mexico, Morocco, the Netherlands, New Zealand, Norway, Peru, the Philippines, Poland, Portugal, Russia, Singapore, South Africa, South Korea, Spain, Sweden, Switzerland, Taiwan, Thailand, Turkey and the United Kingdom (together, the “ACWI ex US countries”). As of September 30, 2011, the Underlying Index was comprised of 1,869 securities. Component companies include energy, financial, industrial and material companies.

BFA uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to “beat” the index it tracks and does not seek temporary defensive positions when markets decline or appear overvalued.

Indexing may eliminate the chance that the Fund will substantially outperform the Underlying Index but also may reduce some of the risks of active management, such as poor security selection. Indexing seeks to achieve lower costs and better after-tax performance by keeping portfolio turnover low in comparison to actively managed investment companies.

BFA uses a representative sampling indexing strategy to manage the Fund. “Representative sampling” is an indexing strategy that involves investing in a representative sample of securities that collectively has an investment profile similar to the Underlying Index. The securities selected are expected to have, in the aggregate, investment characteristics (based on factors such as market capitalization and industry weightings), fundamental characteristics (such as return variability and yield) and liquidity measures similar to those of the Underlying Index. The Fund may or may not hold all of the securities in the Underlying Index.

The Fund generally invests at least 90% of its assets in securities of the Underlying Index and in depositary receipts representing securities of the Underlying Index. The Fund may invest the remainder of its assets in securities not included in the Underlying Index, but which BFA believes will help the Fund track the Underlying Index and in

S-2   


Table Of Contents



other investments including futures contracts, options on futures contracts, options and swaps as well as cash and cash equivalents, including shares of money market funds advised by BFA or its affiliates.

The Fund may lend securities representing up to one-third of the value of the Fund’s total assets (including the value of the collateral received).

The Underlying Index is sponsored by an organization (the “Index Provider”) that is independent of the Fund and BFA. The Index Provider determines the composition and relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index. The Fund’s Index Provider is MSCI Inc. (“MSCI”).

Industry Concentration Policy. The Fund will concentrate its investments (i.e., hold 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. For purposes of this limitation, securities of the U.S. government (including its agencies and instrumentalities) and repurchase agreements collateralized by U.S. government securities are not considered to be issued by members of any industry.

Summary of Principal Risks

As with any investment, you could lose all or part of your investment in the Fund, and the Fund’s performance could trail that of other investments. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund’s net asset value per share (“NAV”), trading price, yield, total return and ability to meet its investment objective.

Asset Class Risk. Securities in the Underlying Index or in the Fund’s portfolio may underperform in comparison to the general securities markets or other asset classes.

Concentration Risk. To the extent that the Fund’s investments are concentrated in a particular issuer, region, country, market, industry or asset class, the Fund may be susceptible to loss due to adverse occurrences affecting that issuer, region, country, market, industry or asset class.

Currency Risk. Because the Fund’s NAV is determined in U.S. dollars, the Fund’s NAV could decline if the currency of a non-U.S. market in which the Fund invests depreciates against the U.S. dollar.

Custody Risk. Less developed markets are more likely to experience problems with the clearing and settling of trades and the holding of securities by local banks, agents and depositories.

Emerging Markets Risk. The Fund’s investments in emerging markets may be subject to a greater risk of loss than investments in more developed markets. Emerging markets may be more likely to experience inflation risk, political turmoil and rapid changes in economic conditions than more developed markets. Emerging markets often have less uniformity in accounting and reporting requirements, unreliable securities valuation and greater risk associated with custody of securities.

Energy Sector Risk. The value of securities issued by companies in the energy sector may decline for many reasons, including, without limitation,

S-3   


Table Of Contents



changes in commodity prices, government regulations, energy conservation efforts and potential civil liabilities.

Equity Securities Risk. Equity securities are subject to changes in value and their values may be more volatile than other asset classes.

Financial Sector Risk. Performance of companies in the financial sector may be adversely impacted by many factors, including, among others, government regulations, economic conditions, credit rating downgrades, changes in interest rates, and decreased liquidity in credit markets. This sector has experienced significant losses in the recent past, and the impact of more stringent capital requirements and of recent or future regulation on any individual financial company or on the sector as a whole cannot be predicted.

Geographic Risk. A natural or other disaster could occur in a geographic region in which the Fund invests, which could affect the economy or particular business operations of companies in the specific geographic region, causing an adverse impact on the Fund’s investments in the affected region.

Industrials Sector Risk. The industrials sector is affected by changes in the supply and demand for products and services, product obsolescence, claims for environmental damage or product liability and general economic conditions, among other factors.

Issuer Risk. Fund performance depends on the performance of individual securities to which the Fund has exposure. Changes to the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA’s investment management strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares, losses from trading in secondary markets, periods of high volatility and disruption in the creation/redemption process of the Fund. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV.

Materials Sector Risk. Companies in the materials sector may be adversely impacted by the volatility of commodity prices, exchange rates, depletion of resources, over-production, litigation and government regulations, among other factors.

Mid-Capitalization Companies Risk. The Fund may invest in the securities of mid-capitalization companies. Compared to large-capitalization companies, mid-capitalization companies may be less stable and more susceptible to adverse developments and their securities may be more volatile and less liquid.

Non-Diversification Risk. The Fund may invest a large percentage of its assets in securities issued by or representing a small number of issuers. As a result, the Fund’s performance may depend on the performance of a small number of issuers.



S-4   


Table Of Contents



Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers are subject to the risks associated with investing in those non-U.S. markets, such as heightened risks of inflation or nationalization. The Fund may lose money due to political, economic and geographic events affecting a non-U.S. issuer or market. The Fund is specifically exposed to Asian Economic Risk and European Economic Risk.

Passive Investment Risk. The Fund is not actively managed and BFA does not attempt to take defensive positions under any market conditions, including declining markets.

Privatization Risk. Some countries in which the Fund invests have begun a process of privatizing certain entities and industries. Privatized entities may lose money or be re-nationalized.

Reliance on Trading Partners Risk. The Fund invests in countries whose economies are heavily dependent upon trading with key partners. Any reduction in this trading may have an adverse impact on the Fund’s investments. Through its trading partners, the Fund is particularly exposed to U.S. Trading Partner Risk.

Securities Lending Risk. The Fund may engage in securities lending. Securities lending involves the risk that the Fund may lose money because the borrower of the Fund’s loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Security Risk. Some countries and regions in which the Fund invests have experienced security concerns. Incidents involving a country’s or region’s security may cause uncertainty in these markets and may adversely affect their economies and the Fund’s investments.

Structural Risk. The countries in which the Fund invests may be subject to considerable degrees of economic, political and social instability.

Tracking Error Risk. The performance of the Fund may diverge from that of the Underlying Index. Because the Fund employs a representative sampling strategy, the Fund may experience tracking error to a greater extent than a fund that seeks to replicate an index.

Valuation Risk. The value of the securities in the Fund’s portfolio may change on days when shareholders will not be able to purchase or sell the Fund’s shares.

1 After-tax returns in the table above are calculated using the historical highest individual U.S. federal marginal income tax rates and do not reflect the impact of state or local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown, and after-tax returns shown are not relevant to tax-exempt investors or investors who hold shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts (“IRAs”). Fund returns after taxes on distributions and sale of Fund shares are calculated assuming that an investor has sufficient capital gains of the same character from other investments to offset any capital losses from the sale of Fund shares. As a result, Fund returns after taxes on distributions and sale of Fund shares may exceed Fund returns before taxes and/or returns after taxes on distributions.

Management

Investment Adviser. BlackRock Fund Advisors.

Portfolio Managers. Rene Casis, Diane Hsiung and Greg Savage (the “Portfolio Managers”) are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager supervises a portfolio management team. Mr. Casis, Ms. Hsiung and Mr. Savage have been Portfolio Managers of the Fund since 2010, 2008 and 2008, respectively.

Purchase and Sale of Fund Shares

The Fund is an exchange-traded fund (commonly referred to as an “ETF”). Individual Fund shares may only be purchased and sold on a national securities exchange through a broker-dealer. The price of Fund shares is based on market price, and because ETF shares trade at market prices rather than NAV, shares may trade at a price greater than NAV (a premium) or less than NAV (a discount). The Fund will only issue or redeem shares that have been aggregated into blocks of 200,000 shares or multiples thereof (“Creation Units”) to authorized participants who have entered into agreements with the Fund’s distributor. The Fund generally will issue or redeem Creation Units in return for a designated portfolio of securities (and an amount of cash) that the Fund specifies each day.

Tax Information

The Fund intends to make distributions that may be taxable to you as ordinary income or capital gains, unless you are investing through a tax-deferred arrangement such as a 401(k) plan or an IRA.

Payments to Broker-Dealers and other Financial Intermediaries

If you purchase shares of the Fund through a broker-dealer or other financial intermediary (such as a bank), BFA or other related companies may pay the intermediary for marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems or other services related to the sale or promotion of the Fund. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.

More Information About the Fund

This Prospectus contains important information about investing in the Fund. Please read this Prospectus carefully before you make any investment decisions. Additional information regarding the Fund is available at www.iShares.com.

BFA is the investment adviser to the Fund. Shares of the Fund are listed for trading on The NASDAQ Stock Market (“NASDAQ”). The market price for a share of the Fund may be different from the Fund’s most recent NAV.

ETFs are funds that trade like other publicly-traded securities. The Fund is designed to track an index. Similar to shares of an index mutual fund, each share of the Fund represents a partial ownership in an underlying portfolio of securities intended to track a market index. Unlike shares of a mutual fund, which can be bought and redeemed from the issuing fund by all shareholders at a price based on NAV, shares of the Fund may be purchased or redeemed directly from the Fund at NAV solely by authorized participants. Also unlike shares of a mutual fund, shares of the Fund are listed on a national securities exchange and trade in the secondary market at market prices that change throughout the day.

The Fund invests in a particular segment of the securities markets and seeks to track the performance of a securities index that generally is not representative of the market as a whole. The Fund is designed to be used as part of broader asset allocation strategies. Accordingly, an investment in the Fund should not constitute a complete investment program.

An index is a theoretical financial calculation while the Fund is an actual investment portfolio. The performance of the Fund and the Underlying Index may vary due to transaction costs, non-U.S. currency valuations, asset valuations, corporate actions (such as mergers and spin-offs), timing variances and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions (such as diversification requirements) that apply to the Fund but not to the Underlying Index or to the use of representative sampling. “Tracking error” is the difference between the performance (return) of the Fund’s portfolio and that of the Underlying Index. BFA expects that, over time, the Fund’s tracking error will not exceed 5%. Because the Fund uses a representative sampling indexing strategy, it can be expected to have a larger tracking error than if it used a replication indexing strategy. “Replication” is an indexing strategy in which a fund invests in substantially all of the securities in its underlying index in approximately the same proportions as in the underlying index.

An investment in the Fund is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, BFA or any of its affiliates.

The Fund’s investment objective and the Underlying Index may be changed without shareholder approval.

A Further Discussion of Principal Risks

The Fund is subject to various risks, including the principal risks noted below, any of which may adversely affect the Fund’s NAV, trading price, yield, total return and ability to meet its investment objective. You could lose all or part of your investment in the Fund, and the Fund could underperform other investments.

Asian Economic Risk. Certain Asian economies have experienced over-extension of credit, currency devaluations and restrictions, high unemployment, high inflation, decreased exports and economic recessions. Economic events in any one Asian country may have a significant economic effect on the entire Asian region, as well as on major trading partners outside Asia, and any adverse event in the Asian markets may have a significant adverse effect on some or all of the ACWI ex US countries.

Asset Class Risk. The securities in the Underlying Index or in the Fund’s portfolio may underperform the returns of other securities or indexes that track other countries, groups of countries, regions, industries, groups of industries, markets, asset classes or sectors. Various types of securities or indexes tend to experience cycles of outperformance and underperformance in comparison to the general securities markets.

Concentration Risk. To the extent that the Fund’s portfolio reflects the Underlying Index’s concentration in the securities of a particular issuer or issuers in a particular country, group of countries, region, market, industry, group of industries, sector or asset class, the Fund may be adversely affected by the performance of those securities, may be subject to increased price volatility and may be more susceptible to adverse economic, market, political or regulatory occurrences affecting that issuer, country, group of countries, region, market, industry, group of industries, sector or asset class.

Currency Risk. Because the Fund’s NAV is determined on the basis of the U.S. dollar, investors may lose money if the currency of a non-U.S. market in which the Fund invests depreciates against the U.S. dollar, even if the local currency value of the Fund’s holdings in that market increases.

Custody Risk. Custody risk refers to the risks inherent in the process of clearing and settling trades and the holding of securities by local banks, agents and depositories. Low trading volumes and volatile prices in less developed markets may make trades harder to complete and settle, and governments or trade groups may compel local agents to hold securities in designated depositories that are not subject to independent evaluation. Local agents are held only to the standards of care of their local markets. In general, the less developed a country’s securities market is, the greater the likelihood of custody problems.

Emerging Markets Risk. Investments in emerging markets are subject to a greater risk of loss than investments in more developed markets. This is due to, among other things, the potential for greater market volatility, lower trading volume, inflation, political and economic instability, greater risk of a market shutdown and more governmental limitations on foreign investments than typically found in more developed markets. In addition, emerging markets often have less uniformity in

accounting and reporting requirements, unreliable securities valuation and greater risks associated with custody of securities.

Energy Sector Risk. The energy sector is cyclical and highly dependent on commodities prices. The market values of companies in the energy sector are strongly affected by the levels and volatility of global energy prices, energy supply and demand, capital expenditures on exploration and production, energy conservation efforts, exchange rates and technological advances, among other factors. Companies in this sector may be subject to substantial government regulation and contractual fixed pricing, which may increase the cost of business and limit these companies’ earnings. A significant portion of their revenues depends on a relatively small number of customers, including governmental entities and utilities. As a result, governmental budget constraints may have a material adverse effect on the stock prices of companies in this industry. Energy companies may also operate in countries with less developed regulatory regimes or a history of expropriation, nationalization or other adverse policies. Energy companies also face a significant risk of civil liability from accidents resulting in injury or loss of life or property, pollution or other environmental mishaps, equipment malfunctions or mishandling of materials and a risk of loss from terrorism and natural disasters. Any such event could have serious consequences for the general population of the area affected and result in a material adverse impact on the Fund’s portfolio and the performance of the Fund. Energy companies can be significantly affected by the supply of, and demand for, specific products (e.g., oil and natural gas) and services, exploration and production spending, government regulation, world events and general economic conditions.

Equity Securities Risk. The Fund invests in equity securities, which are subject to changes in value that may be attributable to market perception of a particular issuer or to general stock market fluctuations that affect all issuers. Investments in equity securities may be more volatile than investments in other asset classes.

European Economic Risk. The Economic and Monetary Union of the European Union (the “EU”) requires member countries to comply with restrictions on inflation rates, deficits, interest rates, debt levels and fiscal and monetary controls, each of which may significantly affect every country in Europe. Decreasing imports or exports, changes in governmental or EU regulations on trade, changes in the exchange rate of the euro, the default or threat of default by an EU member country on its sovereign debt, and/or an economic recession in an EU member country may have a significant adverse effect on the economies of EU member countries and their trading partners, including some or all of the ACWI ex US countries. The European financial markets have recently experienced volatility and have been adversely affected by concerns about economic downturns, credit rating downgrades, rising government debt levels and possible default on or restructuring of government debt in several European countries, including Greece, Ireland, Italy, Portugal and Spain. A default or debt restructuring by any European country would adversely impact holders of that country’s debt, and sellers of credit default swaps linked to that country’s creditworthiness, which may be located in countries other than those listed in the previous sentence. These events have adversely affected the value and exchange rate of the euro and may continue to

significantly affect the economies of every country in Europe, including EU member countries that do not use the euro and non-EU member countries.

Financial Sector Risk. Companies in the financial sector of an economy are often subject to governmental regulation and, recently, government intervention and the potential for additional regulation, which may adversely affect the scope of their activities, the prices they can charge and the amount of capital they must maintain. Governmental regulation may change frequently and may have significant adverse consequences for companies in the financial sector, including effects not intended by such regulation. The impact of recent or future regulation in various countries on any individual financial company or on the sector as a whole cannot be predicted. Certain risks may impact the value of investments in the financial sector more severely than investments outside this sector, including the risks associated with companies that operate with substantial financial leverage. Companies in the financial sector may also be adversely affected by increases in interest rates and loan losses, decreases in the availability of money or asset valuations, credit rating downgrades and adverse conditions in other related markets. Over the past few years, the deterioration of the credit markets has impacted a broad range of mortgage, asset-backed, auction rate, sovereign debt and other markets, including non-U.S. credit and interbank money markets, thereby affecting a wide range of financial institutions and markets. This situation has created instability in the financial markets and caused certain financial companies to incur large losses. Some financial companies have experienced declines in the valuations of their assets, taken actions to raise capital (such as the issuance of debt or equity securities), or even ceased operations. Some financial companies have borrowed significant amounts of capital from governments and may face future government-imposed restrictions on their businesses or increased government intervention. These actions have caused the securities of many financial companies to decline in value. Insurance companies, in particular, may be subject to severe price competition, which may have an adverse impact on their profitability.

Geographic Risk. Some markets in which the Fund invests are located in parts of the world that have historically been prone to natural disasters, such as earthquakes, volcanoes, droughts, floods, hurricanes and tsunamis, and are economically sensitive to environmental events. Any natural or other disaster could have a significant adverse impact on the economies of these geographic areas, causing an adverse impact on the Fund’s investments in the affected region.

Industrials Sector Risk. The stock prices of companies in the industrials sector are affected by supply and demand, both for their specific product or service and for industrials sector products in general. The products of manufacturing companies may face obsolescence due to rapid technological developments and frequent new product introduction. Government regulations, world events, economic conditions and exchange rates affect the performance of companies in the industrials sector. Companies in the industrials sector may be adversely affected by liability for environmental damage, product liability claims and exchange rates. The industrials sector may also be adversely affected by changes or trends in commodity prices, which may be influenced by unpredictable factors.

Issuer Risk. The performance of the Fund depends on the performance of individual securities to which the Fund has exposure. Any issuer of these securities may perform poorly, causing the value of its securities to decline. Poor performance may be caused by poor management decisions, competitive pressures, changes in technology, expiration of patent protection, disruptions in supply, labor problems or shortages, corporate restructurings, fraudulent disclosures or other factors. Issuers may, in times of distress or at their own discretion, decide to reduce or eliminate dividends, which may also cause their stock prices to decline.

Management Risk. The Fund may not fully replicate the Underlying Index and may hold securities not included in the Underlying Index. As a result, the Fund is subject to the risk that BFA’s investment management strategy, the implementation of which is subject to a number of constraints, may not produce the intended results.

Market Risk. The Fund could lose money due to short-term market movements and over longer periods during market downturns. Securities may decline in value due to factors affecting securities markets generally or particular industries represented in the markets. The value of a security may decline due to general market conditions, economic trends or events that are not specifically related to the issuer of the security or to factors that affect a particular industry or industries. During a general downturn in the securities markets, multiple asset classes may be negatively affected.

Market Trading Risk

Absence of Active Market. Although shares of the Fund are listed for trading on one or more stock exchanges, there can be no assurance that an active trading market for such shares will develop or be maintained.

Risk of Secondary Listings. The Fund’s shares may be listed or traded on U.S. and non-U.S. stock exchanges other than the U.S. stock exchange where the Fund’s primary listing is maintained. There can be no assurance that the Fund’s shares will continue to trade on any such stock exchange or in any market or that the Fund’s shares will continue to meet the requirements for listing or trading on any exchange or in any market. The Fund’s shares may be less actively traded in certain markets than others, and investors are subject to the execution and settlement risks and market standards of the market where they or their broker direct their trades for execution. Certain information available to investors who trade Fund shares on a U.S. stock exchange during regular U.S. market hours may not be available to investors who trade in other markets, which may result in secondary market prices in such markets being less efficient.

Secondary Market Trading Risk. Shares of the Fund may trade in the secondary market at times when the Fund does not accept orders to purchase or redeem shares. At such times, shares may trade in the secondary market with more significant premiums or discounts than might be experienced at times when the Fund accepts purchase and redemption orders.

Secondary market trading in Fund shares may be halted by a stock exchange because of market conditions or other reasons. In addition, trading in Fund shares on a stock exchange or in any market may be subject to trading halts caused by extraordinary market volatility pursuant to “circuit breaker” rules on the stock exchange or market.

There can be no assurance that the requirements necessary to maintain the listing or trading of Fund shares will continue to be met or will remain unchanged.

Shares of the Fund May Trade at Prices Other Than NAV. Shares of the Fund trade on stock exchanges at prices at, above or below their most recent NAV. The NAV of the Fund is calculated at the end of each business day and fluctuates with changes in the market value of the Fund’s holdings since the most recent calculation. The trading prices of the Fund’s shares fluctuate continuously throughout trading hours based on market supply and demand rather than NAV. The trading prices of the Fund’s shares may deviate significantly from NAV during periods of market volatility. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV. However, because shares can be created and redeemed in Creation Units at NAV (unlike shares of many closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their NAVs), BFA believes that large discounts or premiums to the NAV of the Fund are not likely to be sustained over the long-term. While the creation/redemption feature is designed to make it likely that the Fund’s shares normally will trade on stock exchanges at prices close to the Fund’s next calculated NAV, exchange prices are not expected to correlate exactly with the Fund’s NAV due to timing reasons as well as market supply and demand factors. In addition, disruptions to creations and redemptions or extreme market volatility may result in trading prices for shares of the Fund that differ significantly from its NAV.

Costs of Buying or Selling Fund Shares. Buying or selling Fund shares on an exchange involves two types of costs that apply to all securities transactions. When buying or selling shares of the Fund through a broker, you will likely incur a brokerage commission or other charges imposed by brokers as determined by that broker. In addition, you may incur the cost of the “spread” – that is, the difference between what investors are willing to pay for Fund shares (the “bid” price) and the price at which they are willing to sell Fund shares (the “ask” price). Because of the costs inherent in buying or selling Fund shares, frequent trading may detract significantly from investment results and an investment in Fund shares may not be advisable for investors who anticipate regularly making small investments.

Materials Sector Risk. Companies in the materials sector could be adversely affected by commodity price volatility, exchange rates, import controls, increased competition, depletion of resources, technical progress, labor relations, exchange rates and government regulations, among other factors. Also, companies in the materials sector are at risk of liability for environmental damage and product liability claims. Production of materials may exceed demand as a result of market imbalances or economic downturns, leading to poor investment returns.

Mid-Capitalization Companies Risk. Many of the companies in which the Fund invests are considered mid-capitalization companies. Stock prices of mid-capitalization companies may be more volatile than those of large-capitalization companies and, therefore, the Fund’s share price may be more volatile than those of funds that invest a larger percentage of their assets in stocks issued by large-capitalization companies. Stock prices of mid-capitalization companies are also more vulnerable than those of large-capitalization companies to adverse business or economic developments, and

the stocks of mid-capitalization companies may be less liquid, making it difficult for the Fund to buy and sell them. In addition, mid-capitalization companies generally have less diverse product lines than large-capitalization companies and are more susceptible to adverse developments related to their products.

Non-Diversification Risk. The Fund is classified as “non-diversified.” This means that the Fund may invest a large percentage of its assets in securities issued by or representing a small number of issuers. As a result, the Fund may be more susceptible to the risks associated with these particular issuers, or to a single economic, political or regulatory occurrence affecting these issuers.

Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers are subject to all of the risks of investing in the markets where such issuers are located, including heightened risks of inflation or nationalization and market fluctuations caused by economic and political developments. As a result of investing in non-U.S. securities, the Fund may be subject to increased risk of loss caused by any of the factors listed below:

  • Lower levels of liquidity and market efficiency;
  • Greater securities price volatility;
  • Exchange rate fluctuations and exchange controls;
  • Less availability of public information about issuers;
  • Limitations on foreign ownership of securities;
  • Imposition of withholding or other taxes;
  • Imposition of restrictions on the expatriation of the funds or other assets of the Fund;
  • Higher transaction and custody costs and delays in settlement procedures;
  • Difficulties in enforcing contractual obligations;
  • Lower levels of regulation of the securities market;
  • Weaker accounting, disclosure and reporting requirements; and
  • Legal principles related to corporate governance, directors’ fiduciary duties and liabilities and stockholders’ rights in markets in which the Fund invests may differ and/or may not be as extensive or protective as those that apply in the United States.

Passive Investment Risk. The Fund is not actively managed and may be affected by a general decline in market segments related to the Underlying Index. The Fund invests in securities included in, or representative of, the Underlying Index regardless of their investment merits. BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

Privatization Risk. Some countries in which the Fund invests have begun a process of privatizing certain entities and industries. In some instances, investors in newly privatized entities have suffered losses due to the inability of the newly privatized entities to adjust quickly to a competitive environment or changing regulatory and legal standards or, in some cases, due to re-nationalization of such privatized entities. There is no assurance that such losses will not recur.

Reliance on Trading Partners Risk. The economies of the ACWI ex US countries are dependent on each other and on the United States as key trading partners. Reduction in spending on the products and services of the ACWI ex US countries by any of their key trading partners, institution of tariffs or other trade barriers or a slowdown in the economies of any of their key trading partners may cause an adverse impact on the economies of the ACWI ex US countries.


U.S. Trading Partners Risk. The United States is a significant, and in some cases the most significant, trading partner of or foreign investor in certain ACWI ex US countries and the economies of these countries may be particularly affected by changes in the U.S. economy. Decreasing U.S. imports, new trade regulations, changes in the U.S. dollar exchange rate or a recession in the United States may have a material adverse effect on the economies of ACWI ex US countries.

Securities Lending Risk. The Fund may engage in securities lending. Securities lending involves the risk that the Fund may lose money because the borrower of the Fund’s loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for the loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Security Risk. Some geographic areas in which the Fund invests have experienced acts of terrorism or strained international relations due to territorial disputes, historical animosities or other defense concerns. These situations may cause uncertainty in the markets of these geographic areas and may adversely affect the performance of their economies.

Structural Risk. Certain political, economic, legal and currency risks have contributed to a high degree of price volatility in the equity markets of the ACWI ex US countries and could adversely affect investments in the Fund:

Political and Social Risk. Disparities of wealth, the pace and success of democratization and ethnic, religious and racial disaffection, among other factors, have led to social unrest, violence and labor unrest in some ACWI ex US countries. Unanticipated or sudden political or social developments may result in sudden and significant investment losses.

Economic Risk. Some ACWI ex US countries may experience economic instability, including instability resulting from substantial rates of inflation or significant devaluations of their currency, or economic recessions causing a negative effect on the economies and securities markets of their economies. Some of these countries may also impose restrictions on the exchange or export of currency or adverse currency exchange rates and may be characterized by a lack of available currency hedging instruments.

Expropriation and/ or Nationalization Risk. Investments in certain ACWI ex US countries may be subject to loss due to expropriation or nationalization of assets and property or the imposition of restrictions on foreign investments and repatriation of capital.

Large Government Debt Risk. Chronic structural public sector deficits in some ACWI ex US countries may adversely impact investments in the Fund.

Tracking Error Risk. Imperfect correlation between the Fund’s portfolio securities and those in the Underlying Index, rounding of prices, changes to the Underlying Index and regulatory requirements may cause tracking error, which is the divergence of the Fund’s performance from that of the Underlying Index. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Underlying Index does not. Because the Fund employs a representative sampling strategy, the Fund may experience tracking error to a greater extent than a fund that seeks to replicate an index.

Valuation Risk. Because non-U.S. exchanges may be open on days when the Fund does not price its shares, the value of the securities in the Fund’s portfolio may change on days when shareholders will not be able to purchase or sell the Fund’s shares. In addition, for purposes of calculating the Fund’s NAV, the value of assets denominated in non-U.S. currencies is converted into U.S. dollars using exchange rates deemed appropriate by BFA. This conversion may result in a difference between the prices used to calculate the Fund’s NAV and the prices used by the Underlying Index, which, in turn, could result in a difference between the Fund’s performance and the performance of the Underlying Index.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

Australasian Economic Risk. The economies of Australasia, which include Australia and New Zealand, are dependent on exports from the agricultural and mining sectors. This makes Australasian economies susceptible to fluctuations in the commodity markets. Australasian economies are also increasingly dependent on their growing service industries. Because the economies of Australasia are dependent on the economies of Asia, Europe and the United States as key trading partners and investors, reduction in spending by any of these trading partners on Australasian products and services, or negative changes in any of these economies, may cause an adverse impact on some or all of the Australasian economies.

Consumer Discretionary Sector Risk. The success of consumer product manufacturers and retailers is tied closely to the performance of domestic and international economies, interest rates, exchange rates, competition, consumer confidence, changes in demographics and consumer preferences. Companies in the consumer discretionary sector depend heavily on disposable household income and consumer spending, and may be strongly affected by social trends and marketing campaigns. These companies may be subject to severe competition, which may have an adverse impact on their profitability.

Consumer Staples Sector Risk. The Fund invests in companies in the consumer staples sector. The consumer staples sector may be affected by the permissibility of using various food additives and production methods, marketing campaigns and other

factors affecting consumer demand. Tobacco companies, in particular, may be adversely affected by new laws, regulations and litigation. The consumer staples sector may also be adversely affected by changes or trends in commodity prices, which may be influenced or characterized by unpredictable factors.

Health Care Sector Risk. The profitability of companies in the health care sector may be affected by extensive government regulations, restrictions on government reimbursement for medical expenses, rising costs of medical products and services, pricing pressure, an increased emphasis on outpatient services, limited number of products, industry innovation, changes in technologies and other market developments. Many health care companies are heavily dependent on patent protection. The expiration of patents may adversely affect the profitability of these companies. Many health care companies are subject to extensive litigation based on product liability and similar claims. Health care companies are subject to competitive forces that may make it difficult to raise prices and, in fact, may result in price discounting. Many new products in the health care sector may be subject to regulatory approvals. The process of obtaining such approvals may be long and costly. Companies in the health care sector may be thinly capitalized and may be susceptible to product obsolescence.

Information Technology Sector Risk. Information technology companies face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Like other technology companies, information technology companies may have limited product lines, markets, financial resources or personnel. The products of information technology companies may face obsolescence due to rapid technological developments and frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Companies in the information technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies.

North American Economic Risk. The United States is Canada’s and Mexico’s largest trading and investment partner. The Canadian and Mexican economies are significantly affected by developments in the U.S. economy. Since the implementation of the North American Free Trade Agreement (“NAFTA”) in 1994 among Canada, the United States and Mexico, total merchandise trade between the three countries have increased. To further this relationship, the three NAFTA countries entered into the Security and Prosperity Partnership of North America in March 2005, which may further affect Canada’s and Mexico’s dependency on the U.S. economy. Economic events in any one North American country can have a significant economic effect on the entire North American region, and on some or all of the North American countries in which the Fund invests.

Telecommunications Sector Risk. The telecommunications sector is subject to extensive government regulation. The costs of complying with governmental regulations, delays or failure to receive required regulatory approvals, or the enactment of new adverse regulatory requirements may negatively affect the business of the telecommunications companies. Government actions around the world, specifically in the area of pre-marketing clearance of products and prices, can be

arbitrary and unpredictable. Companies in the telecommunications sector may encounter distressed cash flows due to the need to commit substantial capital to meet increasing competition, particularly in formulating new products and services using new technology. Technological innovations may make the products and services of telecommunications companies obsolete.

Portfolio Holdings Information

A description of the Trust’s policies and procedures with respect to the disclosure of the Fund’s portfolio securities is available in the Fund’s Statement of Additional Information (“SAI”). The top holdings of the Fund can be found at www.iShares.com. Fund fact sheets provide information regarding the Fund’s top holdings and may be requested by calling 1-800-iShares (1-800-474-2737).

Management

Investment Adviser. As investment adviser, BFA has overall responsibility for the general management and administration of the Trust. BFA provides an investment program for the Fund and manages the investment of the Fund’s assets. In managing the Fund, BFA may draw upon the research and expertise of its asset management affiliates with respect to certain portfolio securities. In seeking to achieve the Fund’s investment objective, BFA uses teams of portfolio managers, investment strategists and other investment specialists. This team approach brings together many disciplines and leverages BFA’s extensive resources.

Pursuant to the Investment Advisory Agreement between BFA and the Trust (entered into on behalf of the Fund), BFA is responsible for substantially all expenses of the Fund, except interest expenses, taxes, brokerage expenses, future distribution fees or expenses and extraordinary expenses.

For its investment advisory services to the Fund, BFA is entitled to receive a management fee from the Fund corresponding to the Fund’s allocable portion of an aggregate management fee based on the aggregate average daily net assets of the following iShares funds: iShares MSCI ACWI ex US Index Fund, iShares MSCI ACWI Index Fund, iShares MSCI All Country World Minimum Volatility Index Fund, iShares MSCI EAFE Index Fund and iShares MSCI EAFE Minimum Volatility Index Fund. The aggregate management fee is calculated as follows: 0.35% per annum of the aggregate net assets less than or equal to $30.0 billion, plus 0.32% per annum of the aggregate net assets over $30.0 billion up to and including $60.0 billion, plus 0.28% per annum of the aggregate net assets in excess of $60.0 billion. As calculated on July 31, 2011, for its investment advisory services to the Fund, BFA is entitled to receive a management fee from the Fund, based on a percentage of the Fund’s average daily net assets, at an annual rate of 0.34%.

BFA is located at 400 Howard Street, San Francisco, CA 94105. It is a wholly owned subsidiary of BTC, which in turn is indirectly wholly-owned by BlackRock, Inc. (“BlackRock”). As of September 30, 2011, BTC and its affiliates, including BFA and BlackRock, provided investment advisory services for assets in excess of $3.35 trillion.

BFA, BTC, BlackRock Execution Services, BlackRock and their affiliates deal, trade and invest for their own accounts in the types of securities in which the Fund may also invest.

A discussion regarding the basis for the Trust’s Board of Trustees’ (the “Board”) approval of the Investment Advisory Agreement with BFA is available in the Fund’s annual report for the period ended July 31.

Portfolio Managers. Rene Casis, Diane Hsiung and Greg Savage are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager is responsible for various functions related to portfolio management, including, but not limited to, investing cash inflows, coordinating with members of his or her portfolio management team to focus on certain asset classes, implementing investment strategy, researching and reviewing investment strategy and overseeing members of his or her portfolio management team that have more limited responsibilities.

Rene Casis has been employed by BFA (formerly, Barclays Global Fund Advisors (“BGFA”)) and BTC (formerly, Barclays Global Investors, N.A. (“BGI”)) as a senior portfolio manager since 2009. From 2005 to 2009, Mr. Casis was a trader at Barclays Capital. Prior to that, Mr. Casis was a portfolio manager from 2000 to 2005 for BGFA and BGI. Mr. Casis has been a Portfolio Manager of the Fund since 2010.

Diane Hsiung has been employed by BFA and BTC as a senior portfolio manager since 2007. Prior to that, Ms. Hsiung was a portfolio manager from 2002 to 2006 for BGFA and BGI. Ms. Hsiung has been a Portfolio Manager of the Fund since 2008.

Greg Savage has been employed by BFA and BTC as a senior portfolio manager since 2006. Prior to that, Mr. Savage was a portfolio manager from 2001 to 2006 for BGFA and BGI. Mr. Savage has been a Portfolio Manager of the Fund since 2008.

The Fund’s SAI provides additional information about the Portfolio Managers’ compensation, other accounts managed by the Portfolio Managers and the Portfolio Managers’ ownership (if any) of shares in the Fund.

Administrator, Custodian and Transfer Agent. State Street Bank and Trust Company (“State Street”) is the administrator, custodian and transfer agent for the Fund.

Conflicts of Interest. BFA wants you to know that there are certain entities with which BFA has relationships that may give rise to conflicts of interest, or the appearance of conflicts of interest. These entities include the following: BFA’s affiliates (including BlackRock and The PNC Financial Services Group, Inc., and each of their affiliates, directors, partners, trustees, managing members, officers and employees (collectively, the “Affiliates”)) and BlackRock’s significant shareholder, Barclays Bank PLC and its affiliates, including Barclays PLC (each, an “Entity” and together, the “Entities”).

The activities of BFA, the Affiliates and the Entities in the management of, or their interest in, their own accounts and other accounts they manage, may present conflicts of interest that could disadvantage the Fund and its shareholders. BFA and its Affiliates or the Entities provide investment management services to other funds and discretionary managed accounts that may follow an investment program similar to that

of the Fund. BFA, its Affiliates and the Entities are involved worldwide with a broad spectrum of financial services and asset management activities and may engage in the ordinary course of business in activities in which their interests or the interests of their clients may conflict with those of the Fund. BFA, one or more of the Affiliates or the Entities acts, or may act, as an investor, investment banker, research provider, investment manager, financier, underwriter, advisor, market maker, trader, prime broker, lender, agent or principal, and have other direct and indirect interests, in securities, currencies and other instruments in which the Fund may directly or indirectly invest. Thus, it is likely that the Fund will have multiple business relationships with and will invest in, engage in transactions with, make voting decisions with respect to, or obtain services from, entities for which BFA, an Affiliate or an Entity performs or seeks to perform investment banking or other services.

BFA or one or more Affiliates or Entities may engage in proprietary trading and advise accounts and funds that have investment objectives similar to those of the Fund and/or that engage in and compete for transactions in the same types of securities, currencies and other instruments as the Fund, including in securities issued by other open-end and closed-end investment management companies, including investment companies that are affiliated with the Fund and BFA, to the extent permitted under the Investment Company Act of 1940, as amended (the “1940 Act”). The trading activities of BFA, these Affiliates and Entities are carried out without reference to positions held directly or indirectly by the Fund and may result in BFA, an Affiliate or an Entity having positions that are adverse to those of the Fund.

No Affiliate or Entity is under any obligation to share any investment opportunity, idea or strategy with the Fund. As a result, an Affiliate or an Entity may compete with the Fund for appropriate investment opportunities. As a result of this and several other factors, the results of the Fund’s investment activities may differ from those of an Affiliate or an Entity and of other accounts managed by an Affiliate or an Entity, and it is possible that the Fund could sustain losses during periods in which one or more Affiliates or Entities and other accounts achieve profits on their trading for proprietary or other accounts. The opposite result is also possible.

The Fund may, from time to time, enter into transactions in which BFA or an Affiliate’s or an Entity’s clients have an interest adverse to the Fund. Furthermore, transactions undertaken by Affiliate-advised clients may adversely impact the Fund. Transactions by one or more Affiliate- or Entity-advised clients or BFA may have the effect of diluting or otherwise disadvantaging the values, prices or investment strategies of the Fund.

An Entity may maintain securities indices as part of its product offerings. Index-based funds seek to track the performance of securities indices and may use the name of the index in the fund name. Index providers, including the Entities, may be paid licensing fees for use of their indices or index names. Entities will not be obligated to license their indices to BFA and its Affiliates, and BFA and its Affiliates will not be assured that the terms of any index licensing agreement with the Entities will be as favorable as those terms offered to other index licensees.

The Fund’s activities may be limited because of regulatory restrictions applicable to one or more Affiliates or Entities, and/or their internal policies designed to comply with such restrictions. In addition, the Fund may invest in securities of companies with

which an Affiliate or an Entity has or is trying to develop investment banking relationships or in which an Affiliate or an Entity has significant debt or equity investments. The Fund also may invest in securities of companies for which an Affiliate or an Entity provides or may some day provide research coverage. An Affiliate or an Entity may have business relationships with and purchase or distribute or sell services or products from or to distributors, consultants or others who recommend the Fund or who engage in transactions with or for the Fund, and may receive compensation for such services. The Fund may also make brokerage and other payments to Affiliates or Entities in connection with the Fund’s portfolio investment transactions.

Pursuant to a securities lending program approved by the Board, the Fund has retained an Affiliate of BFA to serve as the securities lending agent for the Fund to the extent that the Fund participates in the securities lending program. For these services, the lending agent may receive a fee from the Fund, including a fee based on the returns earned on the Fund’s investment of the cash received as collateral for any loaned securities. In addition, one or more Affiliates may be among the entities to which the Fund may lend its portfolio securities under the securities lending program.

The activities of BFA, the Affiliates or Entities may give rise to other conflicts of interest that could disadvantage the Fund and its shareholders. BFA has adopted policies and procedures designed to address these potential conflicts of interest. See the Fund’s SAI for further information.

Buying and Selling Shares. Shares of the Fund may be acquired or redeemed directly from the Fund only in Creation Units or multiples thereof, as discussed in the Creations and Redemptions section of this Prospectus. Only an Authorized Participant (as defined in the Creations and Redemptions section) may engage in creation or redemption transactions directly with the Fund. Once created, shares of the Fund generally trade in the secondary market in amounts less than a Creation Unit.

Shares of the Fund are listed on a national securities exchange for trading during the trading day. Shares can be bought and sold throughout the trading day like shares of other publicly-traded companies. The Trust does not impose any minimum investment for shares of the Fund purchased on an exchange. The Fund’s shares trade under the trading symbol “ACWX.”

Buying or selling Fund shares on an exchange involves two types of costs that may apply to all securities transactions. When buying or selling shares of the Fund through a broker, you will likely incur a brokerage commission or other charges determined by your broker. The commission is frequently a fixed amount and may be a significant proportional cost for investors seeking to buy or sell small amounts of shares. In addition, you may incur the cost of the “spread” – that is, any difference between the bid price and the ask price. The spread varies over time for shares of the Fund based on its trading volume and market liquidity, and is generally lower if the Fund has a lot

of trading volume and market liquidity, and higher if the Fund has little trading volume and market liquidity.

The Board has adopted a policy of not monitoring for frequent purchases and redemptions of Fund shares (“frequent trading”) that appear to attempt to take advantage of a potential arbitrage opportunity presented by a lag between a change in the value of the Fund’s portfolio securities after the close of the primary markets for the Fund’s portfolio securities and the reflection of that change in the Fund’s NAV (“market timing”), because the Fund generally sells and redeems its shares directly through transactions that are in-kind and/or for cash, subject to the conditions described below under Creations and Redemptions. The Board has not adopted a policy of monitoring for other frequent trading activity because shares of the Fund are listed for trading on a national securities exchange.

The national securities exchange on which the Fund’s shares are listed is open for trading Monday through Friday and is closed on weekends and the following holidays: New Year’s Day, Martin Luther King, Jr. Day, Presidents’ Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day. The Fund’s primary listing exchange is NASDAQ.

Section 12(d)(1) of the 1940 Act restricts investments by investment companies in the securities of other investment companies. Registered investment companies are permitted to invest in the Fund beyond the limits set forth in Section 12(d)(1), subject to certain terms and conditions set forth in SEC rules or in an SEC exemptive order issued to the Trust. In order for a registered investment company to invest in shares of the Fund beyond the limitations of Section 12(d)(1) pursuant to the exemptive relief obtained by the Trust, the registered investment company must enter into an agreement with the Trust.

Book Entry. Shares of the Fund are held in book-entry form, which means that no stock certificates are issued. The Depository Trust Company (“DTC”) or its nominee is the record owner of all outstanding shares of the Fund and is recognized as the owner of all shares for all purposes.

Investors owning shares of the Fund are beneficial owners as shown on the records of DTC or its participants. DTC serves as the securities depository for shares of the Fund. DTC participants include securities brokers and dealers, banks, trust companies, clearing corporations and other institutions that directly or indirectly maintain a custodial relationship with DTC. As a beneficial owner of shares, you are not entitled to receive physical delivery of stock certificates or to have shares registered in your name, and you are not considered a registered owner of shares. Therefore, to exercise any right as an owner of shares, you must rely upon the procedures of DTC and its participants. These procedures are the same as those that apply to any other securities that you hold in book-entry or “street name” form.

Share Prices. The trading prices of the Fund’s shares in the secondary market generally differ from the Fund’s daily NAV and are affected by market forces such as supply and demand, economic conditions and other factors. Information regarding the intraday value of shares of the Fund, also known as the “indicative optimized portfolio value” (“IOPV”), is disseminated every 15 seconds throughout the trading day by the

national securities exchange on which the Fund’s shares are listed or by market data vendors or other information providers. The IOPV is based on the current market value of the securities and/or cash required to be deposited in exchange for a Creation Unit. The IOPV does not necessarily reflect the precise composition of the current portfolio of securities held by the Fund at a particular point in time or the best possible valuation of the current portfolio. Therefore, the IOPV should not be viewed as a “real-time” update of the Fund’s NAV, which is computed only once a day. The IOPV is generally determined by using both current market quotations and/or price quotations obtained from broker-dealers that may trade in the portfolio securities held by the Fund. The quotations of certain Fund holdings may not be updated during U.S. trading hours if such holdings do not trade in the United States. The Fund is not involved in, or responsible for, the calculation or dissemination of the IOPV and makes no representation or warranty as to its accuracy.

Determination of Net Asset Value. The NAV of the Fund normally is determined once daily Monday through Friday, generally as of the regularly scheduled close of business of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m., Eastern time) on each day that the NYSE is open for trading, based on prices at the time of closing provided that (a) any Fund assets or liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers (as detailed below) and (b) U.S. fixed income assets may be valued as of the announced closing time for trading in fixed income instruments in a particular market or exchange. The NAV of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets held by the Fund, and its liabilities, are determined pursuant to valuation policies and procedures approved by the Board. The Fund’s assets and liabilities are valued primarily on the basis of market quotations.

Equity investments are valued at market value, which is generally determined using the last reported official closing price or last trading price on the exchange or market on which the security is primarily traded at the time of valuation.

The Fund invests in foreign securities. Foreign currency exchange rates are generally determined as of 4:00 p.m., London time. Foreign securities owned by the Fund may trade on weekends or other days when the Fund does not price its shares. As a result, the Fund’s NAV may change on days when Authorized Participants will not be able to purchase or redeem Fund shares.

Generally, trading in foreign securities, U.S. government securities, money market instruments and certain fixed-income securities is substantially completed each day at various times prior to the close of business on the NYSE. The values of such securities used in computing the NAV of the Fund are determined as of such times.

When market quotations are not readily available or are believed by BFA to be unreliable, the Fund’s investments are valued at fair value. Fair value determinations are made by BFA in accordance with policies and procedures approved by the Fund’s Board. BFA may conclude that a market quotation is not readily available or is

unreliable if a security or other asset or liability does not have a price source due to its lack of liquidity, if a market quotation differs significantly from recent price quotations or otherwise no longer appears to reflect fair value, where the security or other asset or liability is thinly traded, or where there is a significant event subsequent to the most recent market quotation. A “significant event” is an event that, in the judgment of BFA, is likely to cause a material change to the closing market price of the asset or liability held by the Fund. Foreign securities whose values are affected by volatility that occurs in U.S. markets on a trading day after the close of foreign securities markets may be fair valued.

Fair value represents a good faith approximation of the value of an asset or liability. The fair value of an asset or liability held by the Fund is the amount the Fund might reasonably expect to receive from the current sale of that asset or the cost to extinguish that liability in an arm’s-length transaction. Valuing the Fund’s investments using fair value pricing will result in prices that may differ from current market valuations and that may not be the price at which those investments could have been sold during the period in which the particular fair values were used. Use of fair value prices and certain current market valuations could result in a difference between the prices used to calculate the Fund’s NAV and the prices used by the Underlying Index, which, in turn, could result in a difference between the Fund’s performance and the performance of the Underlying Index.

The value of assets or liabilities denominated in non-U.S. currencies will be converted into U.S. dollars using exchange rates deemed appropriate by BFA as investment adviser. Use of a rate different from the rate used by the Index Provider may adversely affect the Fund’s ability to track the Underlying Index.

Dividends and Distributions

General Policies. Dividends from net investment income, if any, generally are declared and paid semi-annually by the Fund. Distributions of net realized securities gains, if any, generally are declared and paid once a year, but the Trust may make distributions on a more frequent basis for the Fund. The Trust reserves the right to declare special distributions if, in its reasonable discretion, such action is necessary or advisable to preserve its status as a regulated investment company (“RIC”) or to avoid imposition of income or excise taxes on undistributed income or realized gains.

Dividends and other distributions on shares of the Fund are distributed on a pro rata basis to beneficial owners of such shares. Dividend payments are made through DTC participants and indirect participants to beneficial owners then of record with proceeds received from the Fund.

Dividend Reinvestment Service. No dividend reinvestment service is provided by the Trust. Broker-dealers may make available the DTC book-entry Dividend Reinvestment Service for use by beneficial owners of the Fund for reinvestment of their dividend distributions. Beneficial owners should contact their broker to determine the availability and costs of the service and the details of participation therein. Brokers may require beneficial owners to adhere to specific procedures and timetables. If this service is available and used, dividend distributions of both income and realized gains

will be automatically reinvested in additional whole shares of the Fund purchased in the secondary market.

Taxes. As with any investment, you should consider how your investment in shares of the Fund will be taxed. The tax information in this Prospectus is provided as general information, based on current law. You should consult your own tax professional about the tax consequences of an investment in shares of the Fund.

Unless your investment in Fund shares is made through a tax-exempt entity or tax-deferred retirement account, such as an IRA, you need to be aware of the possible tax consequences when the Fund makes distributions or you sell Fund shares.

Taxes on Distributions. Distributions from the Fund’s net investment income (other than qualified dividend income), including distributions of income from securities lending and distributions out of the Fund’s net short-term capital gains, if any, are taxable to you as ordinary income. Distributions by the Fund of net long-term capital gains in excess of net short-term capital losses (capital gain dividends) are taxable to you as long-term capital gains, generally at a 15% tax rate (0% at certain income levels), regardless of how long you have held the Fund’s shares. Distributions by the Fund that qualify as qualified dividend income are taxable to you at long-term capital gain rates for taxable years beginning on or before December 31, 2012. The 15% and 0% tax rates expire for taxable years beginning after December 31, 2012. Maximum long-term capital gain income tax rates are scheduled to rise to 20% in 2013. Beginning in 2013, a 3.8% U.S. federal Medicare contribution tax will be imposed on “net investment income,” including interest, dividends, and capital gains, of U.S. individuals with income exceeding $200,000 (or $250,000 if married and filing jointly), and of estates and trusts.

Dividends will be qualified dividend income to you if they are attributable to qualified dividend income received by the Fund. Generally, qualified dividend income includes dividend income from taxable U.S. corporations and qualified non-U.S. corporations, provided that the Fund satisfies certain holding period requirements in respect of the stock of such corporations and has not hedged its position in the stock in certain ways. Substitute dividends received by the Fund with respect to dividends paid on securities lent out will not be qualified dividend income. For this purpose, a qualified non-U.S. corporation means any non-U.S. corporation that is eligible for benefits under a comprehensive income tax treaty with the United States, which includes an exchange of information program or if the stock with respect to which the dividend was paid is readily tradable on an established United States securities market. The term excludes a corporation that is a passive foreign investment company.

Dividends received by the Fund from a real estate investment trust (“REIT”) or another RIC generally are qualified dividend income only to the extent the dividend distributions are made out of qualified dividend income received by such REIT or RIC. It is expected that dividends received by the Fund from a REIT and distributed to a shareholder generally will be taxable to the shareholder as ordinary income.

For a dividend to be treated as qualified dividend income, the dividend must be received with respect to a share of stock held without being hedged by the Fund, and with respect to a share of the Fund held without being hedged by you, for 61 days

during the 121-day period beginning at the date which is 60 days before the date on which such share becomes ex-dividend with respect to such dividend or, in the case of certain preferred stock, 91 days during the 181-day period beginning 90 days before such date.

If your Fund shares are loaned out pursuant to a securities lending arrangement, you may lose the ability to use foreign tax credits passed through by the Fund or to treat Fund dividends paid while the shares are held by the borrower as qualified dividend income.

In general, your distributions are subject to U.S. federal income tax for the year when they are paid. Certain distributions paid in January, however, may be treated as paid on December 31 of the prior year.

If the Fund’s distributions exceed current and accumulated earnings and profits, all or a portion of the distributions made in the taxable year may be recharacterized as a return of capital to shareholders. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and result in a higher capital gain or lower capital loss when those shares on which the distribution was received are sold. Once a shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain, if the shareholder holds shares of the Fund as capital assets.

If you are neither a resident nor a citizen of the United States or if you are a non-U.S. entity, the Fund’s ordinary income dividends (which include distributions of net short-term capital gains) will generally be subject to a 30% U.S. withholding tax, unless a lower treaty rate applies, provided that withholding tax will generally not apply to any gain or income realized by a non-U.S. shareholder in respect of any distributions of long-term capital gains or upon the sale or other disposition of shares of the Fund.

A 30% withholding tax will be imposed on dividends paid after December 31, 2013, and redemption proceeds paid after December 31, 2014, to (i) foreign financial institutions including non-U.S. investment funds unless they agree to collect and disclose to the Internal Revenue Service (“IRS”) information regarding their direct and indirect U.S. account holders and (ii) certain other foreign entities, unless they certify certain information regarding their direct and indirect U.S. owners. To avoid withholding, foreign financial institutions will need to enter into agreements with the IRS that state that they will provide the IRS information, including the name, address and taxpayer identification number of direct and indirect U.S. account holders, comply with due diligence procedures with respect to the identification of U.S. accounts, report to the IRS certain information with respect to U.S. accounts maintained, agree to withhold tax on certain payments made to non-compliant foreign financial institutions or to account holders who fail to provide the required information, and determine certain other information as to their account holders. Other foreign entities will need to provide the name, address, and taxpayer identification number of each substantial U.S. owner or certifications of no substantial U.S. ownership unless certain exceptions apply.

Dividends, interest and capital gains earned by the Fund with respect to non-U.S. securities may give rise to withholding and other taxes imposed by non-U.S. countries. Tax conventions between certain countries and the United States may reduce or

eliminate such taxes. If more than 50% of the total assets of the Fund at the close of a year consists of non-U.S. stocks or securities, the Fund may “pass through” to you certain non-U.S. income taxes (including withholding taxes) paid by the Fund. This means that you would be considered to have received as an additional dividend your share of such non-U.S. taxes, but you may be entitled to either a corresponding tax deduction in calculating your taxable income, or, subject to certain limitations, a credit in calculating your U.S. federal income tax.

For purposes of foreign tax credits for U.S. shareholders of the Fund, foreign capital gains taxes may not produce associated foreign source income, thereby limiting a U.S. person’s ability to use such credits.

If you are a resident or a citizen of the United States, by law, back-up withholding will apply to your distributions and proceeds if you have not provided a taxpayer identification number or social security number and made other required certifications.

Taxes When Shares are Sold. Currently, any capital gain or loss realized upon a sale of Fund shares is generally treated as a long-term gain or loss if the shares have been held for more than one year. Any capital gain or loss realized upon a sale of Fund shares held for one year or less is generally treated as short-term gain or loss, except that any capital loss on the sale of shares held for six months or less is treated as long-term capital loss to the extent that capital gain dividends were paid with respect to such shares. Beginning in 2013, any such capital gains, including from sales of Fund shares or from capital gain dividends, will be included in “net investment income” for purposes of the 3.8% U.S. federal Medicare contribution tax mentioned above.

The foregoing discussion summarizes some of the consequences under current U.S. federal tax law of an investment in the Fund. It is not a substitute for personal tax advice. You may also be subject to state and local taxation on Fund distributions and sales of shares. Consult your personal tax adviser about the potential tax consequences of an investment in shares of the Fund under all applicable tax laws.

Creations and Redemptions. Prior to trading in the secondary market, shares of the Fund are “created” at NAV by market makers, large investors and institutions only in block-size Creation Units of 200,000 shares or multiples thereof. Each “creator” or “Authorized Participant” enters into an authorized participant agreement with the Fund’s distributor, SEI Investments Distribution Co. (the “Distributor”). Only an Authorized Participant may create or redeem Creation Units directly with the Fund. A creation transaction, which is subject to acceptance by the transfer agent, generally takes place when an Authorized Participant deposits into the Fund a designated portfolio of securities and a specified amount of cash approximating the holdings of the Fund in exchange for a specified number of Creation Units. To the extent practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund.

Similarly, shares can be redeemed only in Creation Units, generally for a designated portfolio of securities and a specified amount of cash held by the Fund (“Fund Securities”). Except when aggregated in Creation Units, shares are not redeemable by the Fund. The prices at which creations and redemptions occur are based on the next

calculation of NAV after an order is received in a form described in the authorized participant agreement.

The Fund intends to comply with the U.S. federal securities laws in accepting securities for deposit and satisfying redemptions with redemption securities by, among other means, assuring that any securities accepted for deposit and any securities used to satisfy redemption requests will be sold in transactions that would be exempt from registration under the Securities Act of 1933, as amended (the “1933 Act”). Further, an Authorized Participant that is not a “qualified institutional buyer,” as such term is defined under Rule 144A of the 1933 Act, will not be able to receive Fund Securities that are restricted securities eligible for resale under Rule 144A.

Creations and redemptions must be made through a firm that is either a member of the Continuous Net Settlement System of the National Securities Clearing Corporation or a DTC participant and has executed an agreement with the Distributor with respect to creations and redemptions of Creation Unit aggregations. Information about the procedures regarding creation and redemption of Creation Units (including the cut-off times for receipt of creation and redemption orders) is included in the Fund’s SAI.

Because new shares may be created and issued on an ongoing basis, at any point during the life of the Fund a “distribution,” as such term is used in the 1933 Act, may be occurring. Broker-dealers and other persons are cautioned that some activities on their part may, depending on the circumstances, result in their being deemed participants in a distribution in a manner that could render them statutory underwriters and subject to the prospectus delivery and liability provisions of the 1933 Act. Any determination of whether one is an underwriter must take into account all the relevant facts and circumstances of each particular case.

Broker-dealers should also note that dealers who are not “underwriters” but are participating in a distribution (as contrasted to ordinary secondary transactions), and thus dealing with shares that are part of an “unsold allotment” within the meaning of Section 4(3)(C) of the 1933 Act, would be unable to take advantage of the prospectus delivery exemption provided by Section 4(3) of the 1933 Act. For delivery of prospectuses to exchange members, the prospectus delivery mechanism of Rule 153 under the 1933 Act is available only with respect to transactions on a national securities exchange.

Costs Associated with Creations and Redemptions. Authorized Participants are charged standard creation and redemption transaction fees to offset transfer and other transaction costs associated with the issuance and redemption of Creation Units. The standard creation and redemption transaction fees are set forth in the table below. The standard creation transaction fee is charged to the Authorized Participant on the day such Authorized Participant creates a Creation Unit, and is the same regardless of the number of Creation Units purchased by the Authorized Participant on the applicable business day. Similarly, the standard redemption transaction fee is charged to the Authorized Participant on the day such Authorized Participant redeems a Creation Unit, and is the same regardless of the number of Creation Units redeemed by the Authorized Participant on the applicable business day. Creations and redemptions for cash (when cash creations and redemptions (in whole or in part) are available or specified) are also subject to an additional charge (up to the maximum

amounts shown in the table below). This charge is intended to compensate for brokerage, tax, foreign exchange, execution, market impact and other costs and expenses related to cash transactions. Investors who use the services of a broker or other financial intermediary may pay fees for such services.

The following table shows, as of September 30, 2011, the approximate value of one Creation Unit, standard fees and maximum additional charges for creations and redemptions (as described above):

Householding. Householding is an option available to certain Fund investors. Householding is a method of delivery, based on the preference of the individual investor, in which a single copy of certain shareholder documents can be delivered to investors who share the same address, even if their accounts are registered under different names. Please contact your broker-dealer if you are interested in enrolling in householding and receiving a single copy of prospectuses and other shareholder documents, or if you are currently enrolled in householding and wish to change your householding status.

Distribution

The Distributor distributes Creation Units for the Fund on an agency basis. The Distributor does not maintain a secondary market in shares of the Fund. The Distributor has no role in determining the policies of the Fund or the securities that are purchased or sold by the Fund. The Distributor’s principal address is One Freedom Valley Drive, Oaks, PA 19456.

In addition, BFA or its Affiliates make payments to broker-dealers, banks or other financial intermediaries (together, “intermediaries”) related to marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems, or their making shares of the Fund and certain other iShares funds available to their customers. Such payments, which may be significant to the intermediary, are not made by the Fund. Rather, such payments are made by BFA or its Affiliates from their own resources, which come directly or indirectly in part from fees paid by the iShares funds complex. Payments of this type are sometimes referred to as revenue-sharing payments. A financial intermediary may make decisions about which investment options it recommends or makes available, or the level of services provided, to its customers based on the revenue-sharing payments it is eligible to receive. Therefore, such payments to an intermediary create conflicts of interest between the intermediary and its customers and may cause the intermediary to recommend the Fund or other iShares funds over another investment.

More information regarding these payments is contained in the Fund’s SAI. Please contact your salesperson or other investment professional for more information regarding any such payments his or her firm may receive from BFA or its Affiliates.

Financial Highlights

The financial highlights table is intended to help investors understand the Fund’s financial performance since inception. Certain information reflects financial results for a single share of the Fund. The total returns in the table represent the rate that an investor would have earned (or lost) on an investment in the Fund, assuming reinvestment of all dividends and distributions. This information has been audited by PricewaterhouseCoopers LLP, whose report is included, along with the Fund’s financial statements, in the Fund’s Annual Report (available upon request).

Supplemental Information

I. Premium/Discount Information

The table that follows presents information about the differences between the daily market price on secondary markets for shares of the Fund and the Fund’s NAV. NAV is the price at which the Fund issues and redeems shares. It is calculated in accordance with the standard formula for valuing mutual fund shares. The price used to calculate market returns (“Market Price”) of the Fund generally is determined using the midpoint between the highest bid and the lowest offer on the primary securities exchange on which shares of the Fund are listed for trading, as of the time that the Fund’s NAV is calculated. The Fund’s Market Price may be at, above or below its NAV. The NAV of the Fund will fluctuate with changes in the value of its portfolio holdings. The Market Price of the Fund will fluctuate in accordance with changes in its NAV, as well as market supply and demand.

Premiums or discounts are the differences (expressed as a percentage) between the NAV and Market Price of the Fund on a given day, generally at the time the NAV is calculated. A premium is the amount that the Fund is trading above the reported NAV, expressed as a percentage of the NAV. A discount is the amount that the Fund is trading below the reported NAV, expressed as a percentage of the NAV.

The following information shows the frequency of distributions of premiums and discounts for the Fund for each full calendar quarter of 2010 through September 30, 2011.

Each line in the table shows the number of trading days in which the Fund traded within the premium/discount range indicated. The number of trading days in each premium/discount range is also shown as a percentage of the total number of trading days in the period covered by the table. All data presented here represents past performance, which cannot be used to predict future results.

Premium/Discount Range

Greater than 2.0% and Less than 2.5% 2 0.45%
Greater than 1.5% and Less than 2.0% 2 0.45

Less than -1.5% and Greater than -2.0% 7 1.59
Less than -2.0% and Greater than -2.5% 3 0.68
Less than -2.5% 1 0.23
   441 100.00%

II. Total Return Information

The table that follows presents information about the total returns of the Fund and the Underlying Index as of the fiscal year ended July 31, 2011.

“Average Annual Total Returns” represent the average annual change in value of an investment over the periods indicated. “Cumulative Total Returns” represent the total change in value of an investment over the period indicated.

The Fund’s NAV is the value of one share of the Fund as calculated in accordance with the standard formula for valuing mutual fund shares. The NAV return is based on the NAV of the Fund and the market return is based on the Market Price of the Fund. Market Price is determined by using the midpoint between the highest bid and the lowest offer on the primary stock exchange on which shares of the Fund are listed for trading, as of the time that the Fund’s NAV is calculated. Since shares of the Fund did not trade in the secondary market until after the Fund’s inception, for the period from inception to the first day of secondary market trading in shares of the Fund, the NAV of the Fund is used as a proxy for the Market Price to calculate market returns. Market and NAV returns assume that dividends and capital gain distributions have been reinvested in the Fund at Market Price and NAV, respectively.

An index is a statistical composite that tracks a specified financial market or sector. Unlike the Fund, the Underlying Index does not actually hold a portfolio of securities and therefore does not incur the expenses incurred by the Fund. These expenses negatively impact the performance of the Fund. Also, market returns do not include brokerage commissions that may be payable on secondary market transactions. If brokerage commissions were included, market returns would be lower. The returns shown in the following table do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption or sale of Fund shares. The investment return and principal value of shares of the Fund will vary with changes in market conditions. Shares of the Fund may be worth more or less than their original cost when they are redeemed or sold in the market. The Fund’s past performance is no guarantee of future results.

Fund Overview

iSHARES® MSCI ACWI ex US INDUSTRIALS SECTOR INDEX FUND

Ticker: AXID Stock Exchange: NYSE Arca

Investment Objective

The iShares MSCI ACWI ex US Industrials Sector Index Fund (the “Fund”) seeks investment results that correspond generally to the price and yield performance, before fees and expenses, of the MSCI All Country World ex USA Industrials Index (the “Underlying Index”).

Fees and Expenses

The following table describes the fees and expenses that you will incur if you own shares of the Fund. The investment advisory agreement between iShares Trust (the “Trust”) and BlackRock Fund Advisors (“BFA”) (the “Investment Advisory Agreement”) provides that BFA will pay all operating expenses of the Fund, except interest expenses, taxes, brokerage expenses, future distribution fees or expenses, and extraordinary expenses.

You may also incur usual and customary brokerage commissions when buying or selling shares of the Fund, which are not reflected in the example that follows:

Annual Fund Operating Expenses

Example. This Example is intended to help you compare the cost of owning shares of the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

Portfolio Turnover. The Fund may pay transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 9% of the average value of its portfolio.

Principal Investment Strategies

The Underlying Index is a free float-adjusted market capitalization weighted index designed to measure the combined equity market performance of the industrials sector of developed and emerging markets countries, excluding the United States. Component securities include capital goods, commercial and professional services and transportation companies. As of September 30, 2011, the Underlying Index consisted of companies in the following countries or regions: Australia, Austria, Belgium, Brazil, Canada, Chile, China, Colombia, the Czech Republic, Denmark, Egypt, Finland, France, Germany, Greece, Hong Kong, Hungary, India, Indonesia, Ireland, Israel, Italy, Japan, Malaysia, Mexico, Morocco, the Netherlands, New Zealand, Norway, Peru, the Philippines, Poland, Portugal, Russia, Singapore, South Africa, South Korea, Spain, Sweden, Switzerland, Taiwan, Thailand, Turkey and the United Kingdom (together, the “ACWI ex US industrials sector countries”). As of September 30, 2011, the Underlying Index was comprised of 306 securities.

BFA uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to “beat” the index it tracks and does not seek temporary defensive positions when markets decline or appear overvalued.

Indexing may eliminate the chance that the Fund will substantially outperform the Underlying Index but also may reduce some of the risks of active management, such as poor security selection. Indexing seeks to achieve lower costs and better after-tax performance by keeping portfolio turnover low in comparison to actively managed investment companies.

BFA uses a representative sampling indexing strategy to manage the Fund. “Representative sampling” is an indexing strategy that involves investing in a representative sample of securities that collectively has an investment profile similar to the Underlying Index. The securities selected are expected to have, in the aggregate, investment characteristics (based on factors such as market capitalization and industry weightings), fundamental characteristics (such as return variability and yield) and liquidity measures similar to those of the Underlying Index. The Fund may or may not hold all of the securities in the Underlying Index.

The Fund generally invests at least 80% of its assets in securities of the Underlying Index or in depositary receipts representing securities of the Underlying Index. The Fund may invest the remainder of its assets in securities not included in the Underlying Index, but which BFA believes will help the Fund track the Underlying Index and in

S-2   


Table Of Contents



other investments including futures contracts, options on futures contracts, options and swaps related to the Underlying Index, as well as cash and cash equivalents, including shares of money market funds advised by BFA or its affiliates.

The Fund may lend securities representing up to one-third of the value of the Fund’s total assets (including the value of the collateral received).

The Underlying Index is sponsored by an organization (the “Index Provider”) that is independent of the Fund and BFA. The Index Provider determines the composition and relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index. The Fund’s Index Provider is MSCI Inc. (“MSCI”).

Industry Concentration Policy. The Fund will concentrate its investments (i.e., hold 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. For purposes of this limitation, securities of the U.S. government (including its agencies and instrumentalities) and repurchase agreements collateralized by U.S. government securities are not considered to be issued by members of any industry.

Summary of Principal Risks

As with any investment, you could lose all or part of your investment in the Fund, and the Fund’s performance could trail that of other investments. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund’s net asset value per share (“NAV”), trading price, yield, total return and ability to meet its investment objective.

Asset Class Risk. Securities in the Underlying Index or in the Fund’s portfolio may underperform in comparison to the general securities markets or other asset classes.

Capital Goods Sector Risk. The capital goods sector may be affected by fluctuations in the business cycle. Many capital goods are sold internationally and companies in this sector are subject to market conditions in other countries and regions.

Commercial and Professional Services Sector Risk. The commercial and professional services sector may be affected by corporate demand, changes in domestic and international economics, exchange rates, interest rates, competition and fluctuations in the business cycle.

Concentration Risk. To the extent that the Fund’s investments are concentrated in a particular issuer, region, country, market, industry or asset class, the Fund may be susceptible to loss due to adverse occurrences affecting that issuer, region, country, market, industry or asset class.

Currency Risk. Because the Fund’s NAV is determined in U.S. dollars, the Fund’s NAV could decline if the currency of a non-U.S. market in which the Fund invests depreciates against the U.S. dollar.

Custody Risk. Less developed markets are more likely to experience problems with the clearing and settling of trades and the holding of securities by local banks, agents and depositories.



S-3   


Table Of Contents



Emerging Markets Risk. The Fund’s investments in emerging markets may be subject to a greater risk of loss than investments in more developed markets. Emerging markets may be more likely to experience inflation risk, political turmoil and rapid changes in economic conditions than more developed markets. Emerging markets often have less uniformity in accounting and reporting requirements, unreliable securities valuation and greater risk associated with custody of securities.

Equity Securities Risk. Equity securities are subject to changes in value and their values may be more volatile than other asset classes.

Geographic Risk. A natural or other disaster could occur in a geographic region in which the Fund invests, which could affect the economy or particular business operations of companies in the specific geographic region, causing an adverse impact on the Fund’s investments in the affected region.

Industrials Sector Risk. The industrials sector is affected by changes in the supply and demand for products and services, product obsolescence, claims for environmental damage or product liability and general economic conditions, among other factors.

Issuer Risk. Fund performance depends on the performance of individual securities to which the Fund has exposure. Changes to the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA’s investment management strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares, losses from trading in secondary markets, periods of high volatility and disruption in the creation/redemption process of the Fund. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV.

Mid-Capitalization Companies Risk. The Fund may invest in the securities of mid-capitalization companies. Compared to large-capitalization companies, mid-capitalization companies may be less stable and more susceptible to adverse developments and their securities may be more volatile and less liquid.

Non-Diversification Risk. The Fund may invest a large percentage of its assets in securities issued by or representing a small number of issuers. As a result, the Fund’s performance may depend on the performance of a small number of issuers.

Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers are subject to the risks associated with investing in those non-U.S. markets, such as heightened risks of inflation or nationalization. The Fund may lose money due to political, economic and geographic events affecting a non-U.S. issuer or market. The Fund is specifically exposed to Asian Economic Risk and European Economic Risk.

Table Of Contents



Passive Investment Risk. The Fund is not actively managed and BFA does not attempt to take defensive positions under any market conditions, including declining markets.

Privatization Risk. Some countries in which the Fund invests have begun a process of privatizing certain entities and industries. Privatized entities may lose money or be re-nationalized.

Reliance on Trading Partners Risk. The Fund invests in countries whose economies are heavily dependent upon trading with key partners. Any reduction in this trading may have an adverse impact on the Fund’s investments. Through its trading partners, the Fund is particularly exposed to U.S. Trading Partner Risk.

Risk of Investing in Japan. The Japanese economy may be subject to considerable degrees of economic, political and social instability, which could have a negative impact on Japanese securities.

Securities Lending Risk. The Fund may engage in securities lending. Securities lending involves the risk that the Fund may lose money because the borrower of the Fund’s loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Security Risk. Some countries and regions in which the Fund invests have experienced security concerns. Incidents involving a country’s or region’s security may cause uncertainty in these markets and may adversely affect their economies and the Fund’s investments.

Small-Capitalization Companies Risk. The Fund may invest in the securities of small-capitalization companies. Compared to mid- and large-capitalization companies, small-capitalization companies may be less stable and more susceptible to adverse developments and their securities may be more volatile and less liquid.

Structural Risk. The countries in which the Fund invests may be subject to considerable degrees of economic, political and social instability.

Tracking Error Risk. The performance of the Fund may diverge from that of the Underlying Index. Because the Fund employs a representative sampling strategy, the Fund may experience tracking error to a greater extent than a fund that seeks to replicate an index. BFA EXPECTS THAT THE FUND MAY EXPERIENCE HIGHER TRACKING ERROR THAN IS TYPICAL FOR SIMILAR INDEX EXCHANGE-TRADED FUNDS.

Transportation Sector Risk. The transportation sector can be significantly affected by economic changes, fuel prices, labor relations, insurance costs and government regulations.

Valuation Risk. The value of the securities in the Fund’s portfolio may change on days when shareholders will not be able to purchase or sell the Fund’s shares.

Performance Information

As of the date of the Fund’s prospectus (the “Prospectus”), the Fund has been in operation for less than one full calendar year and therefore does not report its performance information.

Management

Investment Adviser. BlackRock Fund Advisors.

Portfolio Managers. Rene Casis, Diane Hsiung and Greg Savage (the “Portfolio Managers”) are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager supervises a portfolio management team. Mr. Casis has been a Portfolio Manager of the Fund since 2010. Ms. Hsiung and Mr. Savage have been Portfolio Managers of the Fund since inception.

Purchase and Sale of Fund Shares

The Fund is an exchange-traded fund (commonly referred to as an “ETF”). Individual Fund shares may only be purchased and sold on a national securities exchange through a broker-dealer. The price of Fund shares is based on market price, and because ETF shares trade at market prices rather than NAV, shares may trade at a price greater than NAV (a premium) or less than NAV (a discount). The Fund will only issue or redeem shares that have been aggregated into blocks of 50,000 shares or multiples thereof (“Creation Units”) to authorized participants who have entered into agreements with the Fund’s distributor. The Fund generally will issue or redeem Creation Units in return for a designated portfolio of securities (and an amount of cash) that the Fund specifies each day.

Tax Information

The Fund intends to make distributions that may be taxable to you as ordinary income or capital gains, unless you are investing through a tax-deferred arrangement such as a 401(k) plan or an individual retirement account (“IRA”).

Payments to Broker-Dealers and other Financial Intermediaries

If you purchase shares of the Fund through a broker-dealer or other financial intermediary (such as a bank), BFA or other related companies may pay the intermediary for marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems or other services related to the sale or promotion of the Fund. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.

More Information About the Fund

This Prospectus contains important information about investing in the Fund. Please read this Prospectus carefully before you make any investment decisions. Additional information regarding the Fund is available at www.iShares.com.

BFA is the investment adviser to the Fund. Shares of the Fund are listed for trading on NYSE Arca, Inc. (“NYSE Arca”). The market price for a share of the Fund may be different from the Fund’s most recent NAV.

ETFs are funds that trade like other publicly-traded securities. The Fund is designed to track an index. Similar to shares of an index mutual fund, each share of the Fund represents a partial ownership in an underlying portfolio of securities intended to track a market index. Unlike shares of a mutual fund, which can be bought and redeemed from the issuing fund by all shareholders at a price based on NAV, shares of the Fund may be purchased or redeemed directly from the Fund at NAV solely by authorized participants. Also unlike shares of a mutual fund, shares of the Fund are listed on a national securities exchange and trade in the secondary market at market prices that change throughout the day.

The Fund invests in a particular segment of the securities markets and seeks to track the performance of a securities index that generally is not representative of the market as a whole. The Fund is designed to be used as part of broader asset allocation strategies. Accordingly, an investment in the Fund should not constitute a complete investment program.

An index is a theoretical financial calculation while the Fund is an actual investment portfolio. The performance of the Fund and the Underlying Index may vary due to transaction costs, non-U.S. currency valuations, asset valuations, corporate actions (such as mergers and spin-offs), timing variances and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions (such as diversification requirements) that apply to the Fund but not to the Underlying Index or to the use of representative sampling. “Tracking error” is the difference between the performance (return) of the Fund’s portfolio and that of the Underlying Index. BFA expects that, over time, the Fund’s tracking error will not exceed 5%. Because the Fund uses a representative sampling indexing strategy, it can be expected to have a larger tracking error than if it used a replication indexing strategy. “Replication” is an indexing strategy in which a fund invests in substantially all of the securities in its underlying index in approximately the same proportions as in the underlying index.

An investment in the Fund is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, BFA or any of its affiliates.

The Fund’s investment objective and the Underlying Index may be changed without shareholder approval.

A Further Discussion of Principal Risks

The Fund is subject to various risks, including the principal risks noted below, any of which may adversely affect the Fund’s NAV, trading price, yield, total return and ability to meet its investment objective. You could lose all or part of your investment in the Fund, and the Fund could underperform other investments.

Asian Economic Risk. Certain Asian economies have experienced over-extension of credit, currency devaluations and restrictions, high unemployment, high inflation, decreased exports and economic recessions. Economic events in any one Asian country may have a significant economic effect on the entire Asian region, as well as on major trading partners outside Asia, and any adverse event in the Asian markets may have a significant adverse effect on some or all of the ACWI ex US industrials sector countries.

Asset Class Risk. The securities in the Underlying Index or in the Fund’s portfolio may underperform the returns of other securities or indexes that track other countries, groups of countries, regions, industries, groups of industries, markets, asset classes or sectors. Various types of securities or indexes tend to experience cycles of outperformance and underperformance in comparison to the general securities markets.

Capital Goods Sector Risk. The capital goods sector may be affected by fluctuations in the business cycle and by other factors affecting manufacturing demands. The capital goods sector depends heavily on corporate spending. Companies in the capital goods sector may perform well during times of economic expansion, and as economic conditions worsen, the demand for capital goods may decrease. Many capital goods are sold internationally and companies in this sector are subject to market conditions in other countries and regions.

Commercial and Professional Services Sector Risk. The success of commercial and professional service providers is tied closely to the performance of domestic and international economies, interest rates, exchange rates, competition, availability of qualified personnel and corporate demand. The commercial and professional services sector depends heavily on corporate spending. Companies in the commercial and professional services sector may be subject to severe competition, which may also have an adverse impact on their profitability.

Concentration Risk. To the extent that the Fund’s portfolio reflects the Underlying Index’s concentration in the securities of a particular issuer or issuers in a particular country, group of countries, region, market, industry, group of industries, sector or asset class, the Fund may be adversely affected by the performance of those securities, may be subject to increased price volatility and may be more susceptible to adverse economic, market, political or regulatory occurrences affecting that issuer, country, group of countries, region, market, industry, group of industries, sector or asset class.

Currency Risk. Because the Fund’s NAV is determined on the basis of the U.S. dollar, investors may lose money if the currency of a non-U.S. market in which the Fund invests depreciates against the U.S. dollar, even if the local currency value of the Fund’s holdings in that market increases.



Custody Risk. Custody risk refers to the risks inherent in the process of clearing and settling trades and the holding of securities by local banks, agents and depositories. Low trading volumes and volatile prices in less developed markets may make trades harder to complete and settle, and governments or trade groups may compel local agents to hold securities in designated depositories that are not subject to independent evaluation. Local agents are held only to the standards of care of their local markets. In general, the less developed a country’s securities market is, the greater the likelihood of custody problems.

Emerging Markets Risk. Investments in emerging markets are subject to a greater risk of loss than investments in more developed markets. This is due to, among other things, the potential for greater market volatility, lower trading volume, inflation, political and economic instability, greater risk of a market shutdown and more governmental limitations on foreign investments than typically found in more developed markets. In addition, emerging markets often have less uniformity in accounting and reporting requirements, unreliable securities valuation and greater risks associated with custody of securities.

Equity Securities Risk. The Fund invests in equity securities, which are subject to changes in value that may be attributable to market perception of a particular issuer or to general stock market fluctuations that affect all issuers. Investments in equity securities may be more volatile than investments in other asset classes.

European Economic Risk. The Economic and Monetary Union of the European Union (the “EU”) requires member countries to comply with restrictions on inflation rates, deficits, interest rates, debt levels and fiscal and monetary controls, each of which may significantly affect every country in Europe. Decreasing imports or exports, changes in governmental or EU regulations on trade, changes in the exchange rate of the euro, the default or threat of default by an EU member country on its sovereign debt, and/or an economic recession in an EU member country may have a significant adverse effect on the economies of EU member countries and their trading partners, including some or all of the ACWI ex US industrials sector countries. The European financial markets have recently experienced volatility and have been adversely affected by concerns about economic downturns, credit rating downgrades, rising government debt levels and possible default on or restructuring of government debt in several European countries, including Greece, Ireland, Italy, Portugal and Spain. A default or debt restructuring by any European country would adversely impact holders of that country’s debt, and sellers of credit default swaps linked to that country’s creditworthiness, which may be located in countries other than those listed in the previous sentence. These events have adversely affected the value and exchange rate of the euro and may continue to significantly affect the economies of every country in Europe, including EU member countries that do not use the euro and non-EU member countries.

Geographic Risk. Some markets in which the Fund invests are located in parts of the world that have historically been prone to natural disasters, such as earthquakes, volcanoes, droughts, floods, hurricanes and tsunamis, and are economically sensitive to environmental events. Any natural or other disaster could have a significant adverse impact on the economies of these geographic areas, causing an adverse impact on the Fund’s investments in the affected region.

Industrials Sector Risk. The stock prices of companies in the industrials sector are affected by supply and demand, both for their specific product or service and for industrials sector products in general. The products of manufacturing companies may face obsolescence due to rapid technological developments and frequent new product introduction. Government regulations, world events, economic conditions and exchange rates affect the performance of companies in the industrials sector. Companies in the industrials sector may be adversely affected by liability for environmental damage, product liability claims and exchange rates. The industrials sector may also be adversely affected by changes or trends in commodity prices, which may be influenced by unpredictable factors. Aerospace and defense companies, a component of the industrials sector, can be significantly affected by government spending policies because companies involved in this industry rely, to a significant extent, on U.S. and other government demand for their products and services. Thus, the financial condition of, and investor interest in, aerospace and defense companies are heavily influenced by governmental defense spending policies, which are typically under pressure from efforts to control the U.S. and other government budgets. Transportation stocks, a component of the industrials sector, are cyclical and can be significantly affected by economic changes, fuel prices, labor relations and insurance costs. Transportation companies in certain countries may also be subject to significant government regulation and oversight, which may adversely affect their businesses.

Issuer Risk. The performance of the Fund depends on the performance of individual securities to which the Fund has exposure. Any issuer of these securities may perform poorly, causing the value of its securities to decline. Poor performance may be caused by poor management decisions, competitive pressures, changes in technology, expiration of patent protection, disruptions in supply, labor problems or shortages, corporate restructurings, fraudulent disclosures or other factors. Issuers may, in times of distress or at their own discretion, decide to reduce or eliminate dividends, which may also cause their stock prices to decline.

Management Risk. The Fund may not fully replicate the Underlying Index and may hold securities not included in the Underlying Index. As a result, the Fund is subject to the risk that BFA’s investment management strategy, the implementation of which is subject to a number of constraints, may not produce the intended results.

Market Risk. The Fund could lose money due to short-term market movements and over longer periods during market downturns. Securities may decline in value due to factors affecting securities markets generally or particular industries represented in the markets. The value of a security may decline due to general market conditions, economic trends or events that are not specifically related to the issuer of the security or to factors that affect a particular industry or industries. During a general downturn in the securities markets, multiple asset classes may be negatively affected.

Market Trading Risk

Absence of Active Market. Although shares of the Fund are listed for trading on one or more stock exchanges, there can be no assurance that an active trading market for such shares will develop or be maintained.

Risk of Secondary Listings. The Fund’s shares may be listed or traded on U.S. and non-U.S. stock exchanges other than the U.S. stock exchange where the Fund’s primary listing is maintained. There can be no assurance that the Fund’s shares will continue to trade on any such stock exchange or in any market or that the Fund’s shares will continue to meet the requirements for listing or trading on any exchange or in any market. The Fund’s shares may be less actively traded in certain markets than others, and investors are subject to the execution and settlement risks and market standards of the market where they or their broker direct their trades for execution. Certain information available to investors who trade Fund shares on a U.S. stock exchange during regular U.S. market hours may not be available to investors who trade in other markets, which may result in secondary market prices in such markets being less efficient.

Secondary Market Trading Risk. Shares of the Fund may trade in the secondary market at times when the Fund does not accept orders to purchase or redeem shares. At such times, shares may trade in the secondary market with more significant premiums or discounts than might be experienced at times when the Fund accepts purchase and redemption orders.

Secondary market trading in Fund shares may be halted by a stock exchange because of market conditions or other reasons. In addition, trading in Fund shares on a stock exchange or in any market may be subject to trading halts caused by extraordinary market volatility pursuant to “circuit breaker” rules on the stock exchange or market. There can be no assurance that the requirements necessary to maintain the listing or trading of Fund shares will continue to be met or will remain unchanged.

Shares of the Fund May Trade at Prices Other Than NAV. Shares of the Fund trade on stock exchanges at prices at, above or below their most recent NAV. The NAV of the Fund is calculated at the end of each business day and fluctuates with changes in the market value of the Fund’s holdings since the most recent calculation. The trading prices of the Fund’s shares fluctuate continuously throughout trading hours based on market supply and demand rather than NAV. The trading prices of the Fund’s shares may deviate significantly from NAV during periods of market volatility. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV. However, because shares can be created and redeemed in Creation Units at NAV (unlike shares of many closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their NAVs), BFA believes that large discounts or premiums to the NAV of the Fund are not likely to be sustained over the long-term. While the creation/redemption feature is designed to make it likely that the Fund’s shares normally will trade on stock exchanges at prices close to the Fund’s next calculated NAV, exchange prices are not expected to correlate exactly with the Fund’s NAV due to timing reasons as well as market supply and demand factors. In addition, disruptions to creations and redemptions or extreme market volatility may result in trading prices for shares of the Fund that differ significantly from its NAV.

Costs of Buying or Selling Fund Shares. Buying or selling Fund shares on an exchange involves two types of costs that apply to all securities transactions. When buying or selling shares of the Fund through a broker, you will likely incur a brokerage

commission or other charges imposed by brokers as determined by that broker. In addition, you may incur the cost of the “spread” – that is, the difference between what investors are willing to pay for Fund shares (the “bid” price) and the price at which they are willing to sell Fund shares (the “ask” price). Because of the costs inherent in buying or selling Fund shares, frequent trading may detract significantly from investment results and an investment in Fund shares may not be advisable for investors who anticipate regularly making small investments.

Mid-Capitalization Companies Risk. Many of the companies in which the Fund invests are considered mid-capitalization companies. Stock prices of mid-capitalization companies may be more volatile than those of large-capitalization companies and, therefore, the Fund’s share price may be more volatile than those of funds that invest a larger percentage of their assets in stocks issued by large-capitalization companies. Stock prices of mid-capitalization companies are also more vulnerable than those of large-capitalization companies to adverse business or economic developments, and the stocks of mid-capitalization companies may be less liquid, making it difficult for the Fund to buy and sell them. In addition, mid-capitalization companies generally have less diverse product lines than large-capitalization companies and are more susceptible to adverse developments related to their products.

Non-Diversification Risk. The Fund is classified as “non-diversified.” This means that the Fund may invest a large percentage of its assets in securities issued by or representing a small number of issuers. As a result, the Fund may be more susceptible to the risks associated with these particular issuers, or to a single economic, political or regulatory occurrence affecting these issuers.

Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers are subject to all of the risks of investing in the markets where such issuers are located, including heightened risks of inflation or nationalization and market fluctuations caused by economic and political developments. As a result of investing in non-U.S. securities, the Fund may be subject to increased risk of loss caused by any of the factors listed below:

  • Lower levels of liquidity and market efficiency;
  • Greater securities price volatility;
  • Exchange rate fluctuations and exchange controls;
  • Less availability of public information about issuers;
  • Limitations on foreign ownership of securities;
  • Imposition of withholding or other taxes;
  • Imposition of restrictions on the expatriation of the funds or other assets of the Fund;
  • Higher transaction and custody costs and delays in settlement procedures;
  • Difficulties in enforcing contractual obligations;
  • Lower levels of regulation of the securities market;
  • Weaker accounting, disclosure and reporting requirements; and
  • Legal principles related to corporate governance, directors’ fiduciary duties and
  • liabilities and stockholders’ rights in markets in which the Fund invests may differ and/or may not be as extensive or protective as those that apply in the United States.

Passive Investment Risk. The Fund is not actively managed and may be affected by a general decline in market segments related to the Underlying Index. The Fund invests in securities included in, or representative of, the Underlying Index regardless of their investment merits. BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

Privatization Risk. Some countries in which the Fund invests have begun a process of privatizing certain entities and industries. In some instances, investors in newly privatized entities have suffered losses due to the inability of the newly privatized entities to adjust quickly to a competitive environment or changing regulatory and legal standards or, in some cases, due to re-nationalization of such privatized entities. There is no assurance that such losses will not recur.

Reliance on Trading Partners Risk. The economies of the ACWI ex US industrials sector countries are dependent on each other and on the United States as key trading partners. Reduction in spending on the products and services of the ACWI ex US industrials sector countries by any of their key trading partners, institution of tariffs or other trade barriers or a slowdown in the economies of any of their key trading partners may cause an adverse impact on the economies of the ACWI ex US industrials sector countries.

U.S. Trading Partners Risk. The United States is a significant, and in some cases the most significant, trading partner of or foreign investor in certain ACWI ex US industrials sector countries and the economies of these countries may be particularly affected by changes in the U.S. economy. Decreasing U.S. imports, new trade regulations, changes in the U.S. dollar exchange rate or a recession in the United States may have a material adverse effect on the economies of ACWI ex US industrials sector countries.

Risk of Investing in Japan. Japan may be subject to political, economic, nuclear, and labor risks. Any of these risks, individually or in the aggregate, can impact an investment made in Japan.

  • Political Risk. Historically, Japan has had unpredictable national politics and may experience frequent political turnover. Future political developments may lead to changes in policy that might adversely affect the Fund’s investments.
  • Large Government Debt Risk. The Japanese economy faces several concerns, including a financial system with large levels of nonperforming loans, over-leveraged corporate balance sheets, extensive cross-ownership by major corporations, a changing corporate governance structure, and large government deficits. These issues may cause a slowdown of the Japanese economy.
  • Currency Risk. The Japanese yen has fluctuated widely at times and any increase in its value may cause a decline in exports that could weaken the economy.
  • Nuclear Risk. The nuclear power plant catastrophe in Japan in March of 2011 may have short-term and long-term effects on the nuclear energy industry, the extent of which are currently unknown.
  • Labor Risk. Japan has an aging workforce. It is a labor market that is undergoing fundamental structural changes, as traditional lifetime employment clashes with the need for increased labor mobility, which may adversely affect Japan’s economic competitiveness.
  • Geographic Risk. Natural disasters, such as earthquakes, could occur in Japan or surrounding areas and could negatively affect the Japanese economy, and, in turn, could negatively affect the Fund.

Securities Lending Risk. The Fund may engage in securities lending. Securities lending involves the risk that the Fund may lose money because the borrower of the Fund’s loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for the loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Security Risk. Some geographic areas in which the Fund invests have experienced acts of terrorism or strained international relations due to territorial disputes, historical animosities or other defense concerns. These situations may cause uncertainty in the markets of these geographic areas and may adversely affect the performance of their economies.

Small-Capitalization Companies Risk. Many of the companies in which the Fund invests are considered small-capitalization companies. Stock prices of small-capitalization companies may be more volatile than those of larger companies and, therefore, the Fund’s share price may be more volatile than those of funds that invest a larger percentage of their assets in stocks issued by mid- or large-capitalization companies. Stock prices of small-capitalization companies are generally more vulnerable than those of mid- or large-capitalization companies to adverse business and economic developments. Securities of small-capitalization companies may be thinly traded, making it difficult for the Fund to buy and sell them. In addition, small-capitalization companies are typically less financially stable than larger, more established companies and may depend on a small number of essential personnel, making them more vulnerable to loss of personnel. Small-capitalization companies also normally have less diverse product lines than mid- or large-capitalization companies and are more susceptible to adverse developments concerning their products.

Structural Risk. Certain political, economic, legal and currency risks have contributed to a high degree of price volatility in the equity markets of the ACWI ex US industrials sector countries and could adversely affect investments in the Fund:

Political and Social Risk. Disparities of wealth, the pace and success of democratization and ethnic, religious and racial disaffection, among other factors, have led to social unrest, violence and labor unrest in some ACWI ex US industrials sector countries. Unanticipated or sudden political or social developments may result in sudden and significant investment losses.

Economic Risk. Some ACWI ex US industrials sector countries may experience economic instability, including instability resulting from substantial rates of inflation or significant devaluations of their currency, or economic recessions causing a negative effect on the economies and securities markets of their economies. Some of these countries may also impose restrictions on the exchange or export of currency or adverse currency exchange rates and may be characterized by a lack of available currency hedging instruments.

Expropriation and/or Nationalization Risk. Investments in certain ACWI ex US industrials sector countries may be subject to loss due to expropriation or nationalization of assets and property or the imposition of restrictions on foreign investments and repatriation of capital.

Large Government Debt Risk. Chronic structural public sector deficits in some ACWI ex US industrials sector countries may adversely impact investments in the Fund.

Tracking Error Risk. Imperfect correlation between the Fund’s portfolio securities and those in the Underlying Index, rounding of prices, changes to the Underlying Index and regulatory requirements may cause tracking error, which is the divergence of the Fund’s performance from that of the Underlying Index. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Underlying Index does not. Because the Fund employs a representative sampling strategy, the Fund may experience tracking error to a greater extent than a fund that seeks to replicate an index. BFA EXPECTS THAT THE FUND MAY EXPERIENCE HIGHER TRACKING ERROR THAN IS TYPICAL FOR SIMILAR INDEX ETFS.

Transportation Sector Risk. Issuers in the transportation sector can be significantly affected by economic changes, fuel prices, labor relations, and insurance costs. Transportation companies in certain countries may also be subject to significant government regulation and oversight, which may adversely affect their businesses. Other risk factors that may affect transportation companies include the risk of increases in fuel and other operating costs and the effects of regulatory changes or other government decisions.

Valuation Risk. Because non-U.S. exchanges may be open on days when the Fund does not price its shares, the value of the securities in the Fund’s portfolio may change on days when shareholders will not be able to purchase or sell the Fund’s shares. In addition, for purposes of calculating the Fund’s NAV, the value of assets denominated in non-U.S. currencies is converted into U.S. dollars using exchange rates deemed appropriate by BFA. This conversion may result in a difference between the prices used to calculate the Fund’s NAV and the prices used by the Underlying Index, which, in turn, could result in a difference between the Fund’s performance and the performance of the Underlying Index.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

North American Economic Risk. The United States is Canada’s and Mexico’s largest trading and investment partner. The Canadian and Mexican economies are significantly affected by developments in the U.S. economy. Since the implementation of the North American Free Trade Agreement (“NAFTA”) in 1994 among Canada, the United States

and Mexico, total merchandise trade between the three countries have increased. To further this relationship, the three NAFTA countries entered into the Security and Prosperity Partnership of North America in March 2005, which may further affect Canada’s and Mexico’s dependency on the U.S. economy. Economic events in any one North American country can have a significant economic effect on the entire North American region, and on some or all of the North American countries in which the Fund invests.

Portfolio Holdings Information

A description of the Trust’s policies and procedures with respect to the disclosure of the Fund’s portfolio securities is available in the Fund’s Statement of Additional Information (“SAI”). The top holdings of the Fund can be found at www.iShares.com. Fund fact sheets provide information regarding the Fund’s top holdings and may be requested by calling 1-800-iShares (1-800-474-2737).

Management

Investment Adviser. As investment adviser, BFA has overall responsibility for the general management and administration of the Trust. BFA provides an investment program for the Fund and manages the investment of the Fund’s assets. In managing the Fund, BFA may draw upon the research and expertise of its asset management affiliates with respect to certain portfolio securities. In seeking to achieve the Fund’s investment objective, BFA uses teams of portfolio managers, investment strategists and other investment specialists. This team approach brings together many disciplines and leverages BFA’s extensive resources.

Pursuant to the Investment Advisory Agreement between BFA and the Trust (entered into on behalf of the Fund), BFA is responsible for substantially all expenses of the Fund, except interest expenses, taxes, brokerage expenses, future distribution fees or expenses and extraordinary expenses.

For its investment advisory services to the Fund, BFA is entitled to receive a management fee from the Fund based on a percentage of the Fund’s average daily net assets, at the annual rate of 0.48%.

BFA is located at 400 Howard Street, San Francisco, CA 94105. It is a wholly owned subsidiary of BTC, which in turn is indirectly wholly-owned by BlackRock, Inc. (“BlackRock”). As of September 30, 2011, BTC and its affiliates, including BFA and BlackRock, provided investment advisory services for assets in excess of $3.35 trillion. BFA, BTC, BlackRock Execution Services, BlackRock and their affiliates deal, trade and invest for their own accounts in the types of securities in which the Fund may also invest.

A discussion regarding the basis for the Trust’s Board of Trustees’ (the “Board”) approval of the Investment Advisory Agreement with BFA is available in the Fund’s annual report for the period ended July 31.

Portfolio Managers. Rene Casis, Diane Hsiung and Greg Savage are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager is responsible for various functions related to portfolio management, including, but not

limited to, investing cash inflows, coordinating with members of his or her portfolio management team to focus on certain asset classes, implementing investment strategy, researching and reviewing investment strategy and overseeing members of his or her portfolio management team that have more limited responsibilities.

Rene Casis has been employed by BFA (formerly, Barclays Global Fund Advisors (“BGFA”)) and BTC (formerly, Barclays Global Investors, N.A. (“BGI”)) as a senior portfolio manager since 2009. From 2005 to 2009, Mr. Casis was a trader at Barclays Capital. Prior to that, Mr. Casis was a portfolio manager from 2000 to 2005 for BGFA and BGI. Mr. Casis has been a Portfolio Manager of the Fund since 2010.

Diane Hsiung has been employed by BFA and BTC as a senior portfolio manager since 2007. Prior to that, Ms. Hsiung was a portfolio manager from 2002 to 2006 for BGFA and BGI. Ms. Hsiung has been a Portfolio Manager of the Fund since inception.

Greg Savage has been employed by BFA and BTC as a senior portfolio manager since 2006. Prior to that, Mr. Savage was a portfolio manager from 2001 to 2006 for BGFA and BGI. Mr. Savage has been a Portfolio Manager of the Fund since inception.

The Fund’s SAI provides additional information about the Portfolio Managers’ compensation, other accounts managed by the Portfolio Managers and the Portfolio Managers’ ownership (if any) of shares in the Fund.

Administrator, Custodian and Transfer Agent. State Street Bank and Trust Company (“State Street”) is the administrator, custodian and transfer agent for the Fund.

Conflicts of Interest. BFA wants you to know that there are certain entities with which BFA has relationships that may give rise to conflicts of interest, or the appearance of conflicts of interest. These entities include the following: BFA’s affiliates (including BlackRock and The PNC Financial Services Group, Inc., and each of their affiliates, directors, partners, trustees, managing members, officers and employees (collectively, the “Affiliates”)) and BlackRock’s significant shareholder, Barclays Bank PLC and its affiliates, including Barclays PLC (each, an “Entity” and together, the “Entities”).

The activities of BFA, the Affiliates and the Entities in the management of, or their interest in, their own accounts and other accounts they manage, may present conflicts of interest that could disadvantage the Fund and the shareholders. BFA and its Affiliates or the Entities provide investment management services to other funds and discretionary managed accounts that may follow an investment program similar to that of the Fund. BFA, its Affiliates and the Entities are involved worldwide with a broad spectrum of financial services and asset management activities and may engage in the ordinary course of business in activities in which their interests or the interests of their clients may conflict with those of the Fund. BFA, one or more of the Affiliates or the Entities acts, or may act, as an investor, investment banker, research provider, investment manager, financier, underwriter, advisor, market maker, trader, prime broker, lender, agent or principal, and have other direct and indirect interests, in securities, currencies and other instruments in which the Fund may directly or indirectly invest. Thus, it is likely that the Fund will have multiple business relationships with and will invest in, engage in transactions with, make voting decisions with respect

to, or obtain services from, entities for which BFA, an Affiliate or an Entity performs or seeks to perform investment banking or other services.

BFA or one or more Affiliates or Entities may engage in proprietary trading and advise accounts and funds that have investment objectives similar to those of the Fund and/or that engage in and compete for transactions in the same types of securities, currencies and other instruments as the Fund, including in securities issued by other open-end and closed-end investment management companies, including investment companies that are affiliated with the Fund and BFA, to the extent permitted under the Investment Company Act of 1940, as amended (the “1940 Act”). The trading activities of BFA, these Affiliates and Entities are carried out without reference to positions held directly or indirectly by the Fund and may result in BFA, an Affiliate or an Entity having positions that are adverse to those of the Fund.

No Affiliate or Entity is under any obligation to share any investment opportunity, idea or strategy with the Fund. As a result, an Affiliate or an Entity may compete with the Fund for appropriate investment opportunities. As a result of this and several other factors, the results of the Fund’s investment activities may differ from those of an Affiliate or an Entity and of other accounts managed by an Affiliate or an Entity, and it is possible that the Fund could sustain losses during periods in which one or more Affiliates or Entities and other accounts achieve profits on their trading for proprietary or other accounts. The opposite result is also possible.

The Fund may, from time to time, enter into transactions in which BFA or an Affiliate’s or an Entity’s clients have an interest adverse to the Fund. Furthermore, transactions undertaken by Affiliate-advised clients may adversely impact the Fund. Transactions by one or more Affiliate- or Entity-advised clients or BFA may have the effect of diluting or otherwise disadvantaging the values, prices or investment strategies of the Fund.

An Entity may maintain securities indices as part of the product offerings. Index-based funds seek to track the performance of securities indices and may use the name of the index in the fund name. Index providers, including the Entities, may be paid licensing fees for use of their indices or index names. Entities will not be obligated to license their indices to BFA and its Affiliates, and BFA and its Affiliates will not be assured that the terms of any index licensing agreement with the Entities will be as favorable as those terms offered to other index licensees.

The Fund’s activities may be limited because of regulatory restrictions applicable to one or more Affiliates or Entities, and/or their internal policies designed to comply with such restrictions. In addition, the Fund may invest in securities of companies with which an Affiliate or an Entity has or is trying to develop investment banking relationships or in which an Affiliate or an Entity has significant debt or equity investments. The Fund also may invest in securities of companies for which an Affiliate or an Entity provides or may some day provide research coverage. An Affiliate or an Entity may have business relationships with and purchase or distribute or sell services or products from or to distributors, consultants or others who recommend the Fund or who engage in transactions with or for the Fund, and may receive compensation for such services. The Fund may also make brokerage and other payments to Affiliates or Entities in connection with the Fund’s portfolio investment transactions.

Pursuant to a securities lending program approved by the Board, the Fund has retained an Affiliate of BFA to serve as the securities lending agent for the Fund to the extent that the Fund participates in the securities lending program. For these services, the lending agent may receive a fee from the Fund, including a fee based on the returns earned on the Fund’s investment of the cash received as collateral for any loaned securities. In addition, one or more Affiliates may be among the entities to which the Fund may lend its portfolio securities under the securities lending program.

The activities of BFA, the Affiliates or Entities may give rise to other conflicts of interest that could disadvantage the Fund and the shareholders. BFA has adopted policies and procedures designed to address these potential conflicts of interest. See the Fund’s SAI for further information.

Shareholder Information

Additional shareholder information, including how to buy and sell shares of the Fund, is available free of charge by calling toll-free: 1-800-iShares (1-800-474-2737) or visiting our website at www.iShares.com.

Buying and Selling Shares. Shares of the Fund may be acquired or redeemed directly from the Fund only in Creation Units or multiples thereof, as discussed in the Creations and Redemptions section of this Prospectus. Only an Authorized Participant (as defined in the Creations and Redemptions section) may engage in creation or redemption transactions directly with the Fund. Once created, shares of the Fund generally trade in the secondary market in amounts less than a Creation Unit.

Shares of the Fund are listed on a national securities exchange for trading during the trading day. Shares can be bought and sold throughout the trading day like shares of other publicly-traded companies. The Trust does not impose any minimum investment for shares of the Fund purchased on an exchange. The Fund’s shares trade under the trading symbol “AXID.”

Buying or selling Fund shares on an exchange involves two types of costs that may apply to all securities transactions. When buying or selling shares of the Fund through a broker, you will likely incur a brokerage commission or other charges determined by your broker. The commission is frequently a fixed amount and may be a significant proportional cost for investors seeking to buy or sell small amounts of shares. In addition, you may incur the cost of the “spread” – that is, any difference between the bid price and the ask price. The spread varies over time for shares of the Fund based on the trading volume and market liquidity, and is generally lower if the Fund has a lot of trading volume and market liquidity, and higher if the Fund has little trading volume and market liquidity.

The Board has adopted a policy of not monitoring for frequent purchases and redemptions of Fund shares (“frequent trading”) that appear to attempt to take advantage of a potential arbitrage opportunity presented by a lag between a change in the value of the Fund’s portfolio securities after the close of the primary markets for the Fund’s portfolio securities and the reflection of that change in the Fund’s NAV (“market timing”), because the Fund generally sells and redeems its shares directly through transactions that are in-kind and/or for cash, subject to the conditions

described below under Creations and Redemptions. The Board has not adopted a policy of monitoring for other frequent trading activity because shares of the Fund are listed for trading on a national securities exchange.

The national securities exchange on which the Fund’s shares are listed is open for trading Monday through Friday and is closed on weekends and the following holidays: New Year’s Day, Martin Luther King, Jr. Day, Presidents’ Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day. The Fund’s primary listing exchange is NYSE Arca.

Section 12(d)(1) of the 1940 Act restricts investments by investment companies in the securities of other investment companies. Registered investment companies are permitted to invest in the Fund beyond the limits set forth in Section 12(d)(1), subject to certain terms and conditions set forth in SEC rules or in an SEC exemptive order issued to the Trust. In order for a registered investment company to invest in shares of the Fund beyond the limitations of Section 12(d)(1) pursuant to the exemptive relief obtained by the Trust, the registered investment company must enter into an agreement with the Trust.

Book Entry. Shares of the Fund are held in book-entry form, which means that no stock certificates are issued. The Depository Trust Company (“DTC”) or its nominee is the record owner of all outstanding shares of the Fund and is recognized as the owner of all shares for all purposes.

Investors owning shares of the Fund are beneficial owners as shown on the records of DTC or its participants. DTC serves as the securities depository for shares of the Fund. DTC participants include securities brokers and dealers, banks, trust companies, clearing corporations and other institutions that directly or indirectly maintain a custodial relationship with DTC. As a beneficial owner of shares, you are not entitled to receive physical delivery of stock certificates or to have shares registered in your name, and you are not considered a registered owner of shares. Therefore, to exercise any right as an owner of shares, you must rely upon the procedures of DTC and its participants. These procedures are the same as those that apply to any other securities that you hold in book-entry or “street name” form.

Share Prices. The trading prices of the Fund’s shares in the secondary market generally differ from the Fund’s daily NAV and are affected by market forces such as supply and demand, economic conditions and other factors. Information regarding the intraday value of shares of the Fund, also known as the “indicative optimized portfolio value” (“IOPV”), is disseminated every 15 seconds throughout the trading day by the national securities exchange on which the Fund’s shares are listed or by market data vendors or other information providers. The IOPV is based on the current market value of the securities and/or cash required to be deposited in exchange for a Creation Unit. The IOPV does not necessarily reflect the precise composition of the current portfolio of securities held by the Fund at a particular point in time or the best possible valuation of the current portfolio. Therefore, the IOPV should not be viewed as a “real-time” update of the Fund’s NAV, which is computed only once a day. The IOPV is generally determined by using both current market quotations and/or price quotations obtained from broker-dealers that may trade in the portfolio securities held by the Fund. The quotations of certain Fund holdings may not be updated during U.S. trading hours if

such holdings do not trade in the United States. The Fund is not involved in, or responsible for, the calculation or dissemination of the IOPV and makes no representation or warranty as to its accuracy.

Determination of Net Asset Value. The NAV of the Fund normally is determined once daily Monday through Friday, generally as of the regularly scheduled close of business of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m., Eastern time) on each day that the NYSE is open for trading, based on prices at the time of closing provided that (a) any Fund assets or liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers (as detailed below) and (b) U.S. fixed income assets may be valued as of the announced closing time for trading in fixed income instruments in a particular market or exchange. The NAV of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets held by the Fund, and its liabilities, are determined pursuant to valuation policies and procedures approved by the Board. The Fund’s assets and liabilities are valued primarily on the basis of market quotations.

Equity investments are valued at market value, which is generally determined using the last reported official closing price or last trading price on the exchange or market on which the security is primarily traded at the time of valuation.

The Fund invests in foreign securities. Foreign currency exchange rates are generally determined as of 4:00 p.m., London time. Foreign securities owned by the Fund may trade on weekends or other days when the Fund does not price its shares. As a result, the Fund’s NAV may change on days when Authorized Participants will not be able to purchase or redeem Fund shares.

Generally, trading in foreign securities, U.S. government securities, money market instruments and certain fixed-income securities is substantially completed each day at various times prior to the close of business on the NYSE. The values of such securities used in computing the NAV of the Fund are determined as of such times.

When market quotations are not readily available or are believed by BFA to be unreliable, the Fund’s investments are valued at fair value. Fair value determinations are made by BFA in accordance with policies and procedures approved by the Fund’s Board. BFA may conclude that a market quotation is not readily available or is unreliable if a security or other asset or liability does not have a price source due to its lack of liquidity, if a market quotation differs significantly from recent price quotations or otherwise no longer appears to reflect fair value, where the security or other asset or liability is thinly traded, or where there is a significant event subsequent to the most recent market quotation. A “significant event” is an event that, in the judgment of BFA, is likely to cause a material change to the closing market price of the asset or liability held by the Fund. Foreign securities whose values are affected by volatility that occurs in U.S. markets on a trading day after the close of foreign securities markets may be fair valued.

Fair value represents a good faith approximation of the value of an asset or liability. The fair value of an asset or liability held by the Fund is the amount the Fund might reasonably expect to receive from the current sale of that asset or the cost to extinguish that liability in an arm’s-length transaction. Valuing the Fund’s investments using fair value pricing will result in prices that may differ from current market valuations and that may not be the price at which those investments could have been sold during the period in which the particular fair values were used. Use of fair value prices and certain current market valuations could result in a difference between the prices used to calculate the Fund’s NAV and the prices used by the Underlying Index, which, in turn, could result in a difference between the Fund’s performance and the performance of the Underlying Index.

The value of assets or liabilities denominated in non-U.S. currencies will be converted into U.S. dollars using exchange rates deemed appropriate by BFA as investment adviser. Use of a rate different from the rate used by the Index Provider may adversely affect the Fund’s ability to track the Underlying Index.

Dividends and Distributions

General Policies. Dividends from net investment income, if any, generally are declared and paid semi-annually by the Fund. Distributions of net realized securities gains, if any, generally are declared and paid once a year, but the Trust may make distributions on a more frequent basis for the Fund. The Trust reserves the right to declare special distributions if, in its reasonable discretion, such action is necessary or advisable to preserve its status as a regulated investment company (“RIC”) or to avoid imposition of income or excise taxes on undistributed income or realized gains.

Dividends and other distributions on shares of the Fund are distributed on a pro rata basis to beneficial owners of such shares. Dividend payments are made through DTC participants and indirect participants to beneficial owners then of record with proceeds received from the Fund.

Dividend Reinvestment Service. No dividend reinvestment service is provided by the Trust. Broker-dealers may make available the DTC book-entry Dividend Reinvestment Service for use by beneficial owners of the Fund for reinvestment of their dividend distributions. Beneficial owners should contact their broker to determine the availability and costs of the service and the details of participation therein. Brokers may require beneficial owners to adhere to specific procedures and timetables. If this service is available and used, dividend distributions of both income and realized gains will be automatically reinvested in additional whole shares of the Fund purchased in the secondary market.

Taxes. As with any investment, you should consider how your investment in shares of the Fund will be taxed. The tax information in this Prospectus is provided as general information, based on current law. You should consult your own tax professional about the tax consequences of an investment in shares of the Fund.

Unless your investment in Fund shares is made through a tax-exempt entity or tax-deferred retirement account, such as an IRA, you need to be aware of the possible tax consequences when the Fund makes distributions or you sell Fund shares.

Taxes on Distributions. Distributions from the Fund’s net investment income (other than qualified dividend income), including distributions of income from securities lending and distributions out of the Fund’s net short-term capital gains, if any, are taxable to you as ordinary income. Distributions by the Fund of net long-term capital gains in excess of net short-term capital losses (capital gain dividends) are taxable to you as long-term capital gains, generally at a 15% tax rate (0% at certain income levels), regardless of how long you have held the Fund’s shares. Distributions by the Fund that qualify as qualified dividend income are taxable to you at long-term capital gain rates for taxable years beginning on or before December 31, 2012. The 15% and 0% tax rates expire for taxable years beginning after December 31, 2012. Maximum long-term capital gain income tax rates are scheduled to rise to 20% in 2013. Beginning in 2013, a 3.8% U.S. federal Medicare contribution tax will be imposed on “net investment income,” including interest, dividends, and capital gains, of U.S. individuals with income exceeding $200,000 (or $250,000 if married and filing jointly), and of estates and trusts.

Dividends will be qualified dividend income to you if they are attributable to qualified dividend income received by the Fund. Generally, qualified dividend income includes dividend income from taxable U.S. corporations and qualified non-U.S. corporations, provided that the Fund satisfies certain holding period requirements in respect of the stock of such corporations and has not hedged its position in the stock in certain ways. Substitute dividends received by the Fund with respect to dividends paid on securities lent out will not be qualified dividend income. For this purpose, a qualified non-U.S. corporation means any non-U.S. corporation that is eligible for benefits under a comprehensive income tax treaty with the United States, which includes an exchange of information program or if the stock with respect to which the dividend was paid is readily tradable on an established United States securities market. The term excludes a corporation that is a passive foreign investment company.

Dividends received by the Fund from a real estate investment trust (“REIT”) or another RIC generally are qualified dividend income only to the extent the dividend distributions are made out of qualified dividend income received by such REIT or RIC. It is expected that dividends received by the Fund from a REIT and distributed to a shareholder generally will be taxable to the shareholder as ordinary income.

For a dividend to be treated as qualified dividend income, the dividend must be received with respect to a share of stock held without being hedged by the Fund, and with respect to a share of the Fund held without being hedged by you, for 61 days during the 121-day period beginning at the date which is 60 days before the date on which such share becomes ex-dividend with respect to such dividend or, in the case of certain preferred stock, 91 days during the 181-day period beginning 90 days before such date.

If your Fund shares are loaned out pursuant to a securities lending arrangement, you may lose the ability to use foreign tax credits passed through by the Fund or to treat Fund dividends paid while the shares are held by the borrower as qualified dividend income.

In general, your distributions are subject to U.S. federal income tax for the year when they are paid. Certain distributions paid in January, however, may be treated as paid on December 31 of the prior year.

If the Fund’s distributions exceed current and accumulated earnings and profits, all or a portion of the distributions made in the taxable year may be recharacterized as a return of capital to shareholders. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and result in a higher capital gain or lower capital loss when those shares on which the distribution was received are sold. Once a shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain, if the shareholder holds shares of the Fund as capital assets.

If you are neither a resident nor a citizen of the United States or if you are a non-U.S. entity, the Fund’s ordinary income dividends (which include distributions of net short-term capital gains) will generally be subject to a 30% U.S. withholding tax, unless a lower treaty rate applies, provided that withholding tax will generally not apply to any gain or income realized by a non-U.S. shareholder in respect of any distributions of long-term capital gains or upon the sale or other disposition of shares of the Fund.

A 30% withholding tax will be imposed on dividends paid after December 31, 2013, and redemption proceeds paid after December 31, 2014, to (i) foreign financial institutions including non-U.S. investment funds unless they agree to collect and disclose to the Internal Revenue Service (“IRS”) information regarding their direct and indirect U.S. account holders and (ii) certain other foreign entities, unless they certify certain information regarding their direct and indirect U.S. owners. To avoid withholding, foreign financial institutions will need to enter into agreements with the IRS that state that they will provide the IRS information, including the name, address and taxpayer identification number of direct and indirect U.S. account holders, comply with due diligence procedures with respect to the identification of U.S. accounts, report to the IRS certain information with respect to U.S. accounts maintained, agree to withhold tax on certain payments made to non-compliant foreign financial institutions or to account holders who fail to provide the required information, and determine certain other information as to their account holders. Other foreign entities will need to provide the name, address, and taxpayer identification number of each substantial U.S. owner or certifications of no substantial U.S. ownership unless certain exceptions apply.

Dividends, interest and capital gains earned by the Fund with respect to non-U.S. securities may give rise to withholding and other taxes imposed by non-U.S. countries. Tax conventions between certain countries and the United States may reduce or eliminate such taxes. If more than 50% of the total assets of the Fund at the close of a year consists of non-U.S. stocks or securities, the Fund may “pass through” to you certain non-U.S. income taxes (including withholding taxes) paid by the Fund. This means that you would be considered to have received as an additional dividend your share of such non-U.S. taxes, but you may be entitled to either a corresponding tax deduction in calculating your taxable income, or, subject to certain limitations, a credit in calculating your U.S. federal income tax.

For purposes of foreign tax credits for U.S. shareholders of the Fund, foreign capital gains taxes may not produce associated foreign source income, thereby limiting a U.S. person’s ability to use such credits.

If you are a resident or a citizen of the United States, by law, back-up withholding will apply to your distributions and proceeds if you have not provided a taxpayer identification number or social security number and made other required certifications.

Taxes When Shares are Sold. Currently, any capital gain or loss realized upon a sale of Fund shares is generally treated as a long-term gain or loss if the shares have been held for more than one year. Any capital gain or loss realized upon a sale of Fund shares held for one year or less is generally treated as short-term gain or loss, except that any capital loss on the sale of shares held for six months or less is treated as long-term capital loss to the extent that capital gain dividends were paid with respect to such shares. Beginning in 2013, any such capital gains, including from sales of Fund shares or from capital gain dividends, will be included in “net investment income” for purposes of the 3.8% U.S. federal Medicare contribution tax mentioned above.

The foregoing discussion summarizes some of the consequences under current U.S. federal tax law of an investment in the Fund. It is not a substitute for personal tax advice. You may also be subject to state and local taxation on Fund distributions and sales of shares. Consult your personal tax adviser about the potential tax consequences of an investment in shares of the Fund under all applicable tax laws.

Creations and Redemptions. Prior to trading in the secondary market, shares of the Fund are “created” at NAV by market makers, large investors and institutions only in block-size Creation Units of 50,000 shares or multiples thereof. Each “creator” or “Authorized Participant” enters into an authorized participant agreement with the Fund’s distributor, SEI Investments Distribution Co. (the “Distributor”). Only an Authorized Participant may create or redeem Creation Units directly with the Fund. A creation transaction, which is subject to acceptance by the transfer agent, generally takes place when an Authorized Participant deposits into the Fund a designated portfolio of securities and a specified amount of cash approximating the holdings of the Fund in exchange for a specified number of Creation Units. To the extent practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund.

Similarly, shares can be redeemed only in Creation Units, generally for a designated portfolio of securities and a specified amount of cash held by the Fund (“Fund Securities”). Except when aggregated in Creation Units, shares are not redeemable by the Fund. The prices at which creations and redemptions occur are based on the next calculation of NAV after an order is received in a form described in the authorized participant agreement.

The Fund intends to comply with the U.S. federal securities laws in accepting securities for deposit and satisfying redemptions with redemption securities by, among other means, assuring that any securities accepted for deposit and any securities used to satisfy redemption requests will be sold in transactions that would be exempt from registration under the Securities Act of 1933, as amended (the “1933 Act”). Further, an Authorized Participant that is not a “qualified institutional buyer,” as such term is

defined under Rule 144A of the 1933 Act, will not be able to receive Fund Securities that are restricted securities eligible for resale under Rule 144A.

Creations and redemptions must be made through a firm that is either a member of the Continuous Net Settlement System of the National Securities Clearing Corporation or a DTC participant and has executed an agreement with the Distributor with respect to creations and redemptions of Creation Unit aggregations. Information about the procedures regarding creation and redemption of Creation Units (including the cut-off times for receipt of creation and redemption orders) is included in the Fund’s SAI.

Because new shares may be created and issued on an ongoing basis, at any point during the life of the Fund a “distribution,” as such term is used in the 1933 Act, may be occurring. Broker-dealers and other persons are cautioned that some activities on their part may, depending on the circumstances, result in their being deemed participants in a distribution in a manner that could render them statutory underwriters and subject to the prospectus delivery and liability provisions of the 1933 Act. Any determination of whether one is an underwriter must take into account all the relevant facts and circumstances of each particular case.

Broker-dealers should also note that dealers who are not “underwriters” but are participating in a distribution (as contrasted to ordinary secondary transactions), and thus dealing with shares that are part of an “unsold allotment” within the meaning of Section 4(3)(C) of the 1933 Act, would be unable to take advantage of the prospectus delivery exemption provided by Section 4(3) of the 1933 Act. For delivery of prospectuses to exchange members, the prospectus delivery mechanism of Rule 153 under the 1933 Act is available only with respect to transactions on a national securities exchange.

Costs Associated with Creations and Redemptions. Authorized Participants are charged standard creation and redemption transaction fees to offset transfer and other transaction costs associated with the issuance and redemption of Creation Units. The standard creation and redemption transaction fees are set forth in the table below. The standard creation transaction fee is charged to the Authorized Participant on the day such Authorized Participant creates a Creation Unit, and is the same regardless of the number of Creation Units purchased by the Authorized Participant on the applicable business day. Similarly, the standard redemption transaction fee is charged to the Authorized Participant on the day such Authorized Participant redeems a Creation Unit, and is the same regardless of the number of Creation Units redeemed by the Authorized Participant on the applicable business day. Creations and redemptions for cash (when cash creations and redemptions (in whole or in part) are available or specified) are also subject to an additional charge (up to the maximum amounts shown in the table below). This charge is intended to compensate for brokerage, tax, foreign exchange, execution, market impact and other costs and expenses related to cash transactions. Investors who use the services of a broker or other financial intermediary may pay fees for such services.

The following table shows, as of September 30, 2011, the approximate value of one Creation Unit, standard fees and maximum additional charges for creations and redemptions (as described above):

Householding. Householding is an option available to certain Fund investors. Householding is a method of delivery, based on the preference of the individual investor, in which a single copy of certain shareholder documents can be delivered to investors who share the same address, even if their accounts are registered under different names. Please contact your broker-dealer if you are interested in enrolling in householding and receiving a single copy of prospectuses and other shareholder documents, or if you are currently enrolled in householding and wish to change your householding status.

Distribution

The Distributor distributes Creation Units for the Fund on an agency basis. The Distributor does not maintain a secondary market in shares of the Fund. The Distributor has no role in determining the policies of the Fund or the securities that are purchased or sold by the Fund. The Distributor’s principal address is One Freedom Valley Drive, Oaks, PA 19456.

In addition, BFA or its Affiliates make payments to broker-dealers, banks or other financial intermediaries (together, “intermediaries”) related to marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems, or their making shares of the Fund and certain other iShares funds available to their customers. Such payments, which may be significant to the intermediary, are not made by the Fund. Rather, such payments are made by BFA or its Affiliates from their own resources, which come directly or indirectly in part from fees paid by the iShares funds complex. Payments of this type are sometimes referred to as revenue-sharing payments. A financial intermediary may make decisions about which investment options it recommends or makes available, or the level of services provided, to its customers based on the revenue-sharing payments it is eligible to receive. Therefore, such payments to an intermediary create conflicts of interest between the intermediary and its customers and may cause the intermediary to recommend the Fund or other iShares funds over another investment. More information regarding these payments is contained in the Fund’s SAI. Please contact your salesperson or other investment professional for more information regarding any such payments his or her firm may receive from BFA or its Affiliates.

Financial Highlights

The financial highlights table is intended to help investors understand the Fund’s financial performance since inception. Certain information reflects financial results for a single share of the Fund. The total returns in the table represent the rate that an investor would have earned (or lost) on an investment in the Fund, assuming reinvestment of all dividends and distributions. This information has been audited by PricewaterhouseCoopers LLP, whose report is included, along with the Fund’s financial statements, in the Fund’s Annual Report (available upon request).

Supplemental Information

I. Premium/Discount Information

The table that follows presents information about the differences between the daily market price on secondary markets for shares of the Fund and the Fund’s NAV. NAV is the price at which the Fund issues and redeems shares. It is calculated in accordance with the standard formula for valuing mutual fund shares. The price used to calculate market returns (“Market Price”) of the Fund generally is determined using the midpoint between the highest bid and the lowest offer on the primary securities exchange on which shares of the Fund are listed for trading, as of the time that the Fund’s NAV is calculated. The Fund’s Market Price may be at, above or below its NAV. The NAV of the Fund will fluctuate with changes in the value of its portfolio holdings. The Market Price of the Fund will fluctuate in accordance with changes in its NAV, as well as market supply and demand.

Premiums or discounts are the differences (expressed as a percentage) between the NAV and Market Price of the Fund on a given day, generally at the time the NAV is calculated. A premium is the amount that the Fund is trading above the reported NAV, expressed as a percentage of the NAV. A discount is the amount that the Fund is trading below the reported NAV, expressed as a percentage of the NAV.

The following information shows the frequency of distributions of premiums and discounts for the Fund from October 1, 2010 through September 30, 2011.

Each line in the table shows the number of trading days in which the Fund traded within the premium/discount range indicated. The number of trading days in each premium/discount range is also shown as a percentage of the total number of trading days in the period covered by the table. All data presented here represents past performance, which cannot be used to predict future results.

Premium/Discount Range

Percentage of Total Days
Greater than 1.5% and Less than 2.0% 3 1.19%
Greater than 1.0% and Less than 1.5% 2 0.79

Less than -3.0% and Greater than -3.5% 1 0.40
   253 100.00%

II. Total Return Information

The table that follows presents information about the total returns of the Fund and the Underlying Index as of the fiscal year ended July 31, 2011.

“Average Annual Total Returns” represent the average annual change in value of an investment over the periods indicated. “Cumulative Total Returns” represent the total change in value of an investment over the period indicated.

The Fund’s NAV is the value of one share of the Fund as calculated in accordance with the standard formula for valuing mutual fund shares. The NAV return is based on the NAV of the Fund and the market return is based on the Market Price of the Fund. Market Price is determined by using the midpoint between the highest bid and the lowest offer on the primary stock exchange on which shares of the Fund are listed for trading, as of the time that the Fund’s NAV is calculated. Since shares of the Fund did not trade in the secondary market until after the Fund’s inception, for the period from inception to the first day of secondary market trading in shares of the Fund, the NAV of the Fund is used as a proxy for the Market Price to calculate market returns. Market and NAV returns assume that dividends and capital gain distributions have been reinvested in the Fund at Market Price and NAV, respectively.

An index is a statistical composite that tracks a specified financial market or sector. Unlike the Fund, the Underlying Index does not actually hold a portfolio of securities and therefore does not incur the expenses incurred by the Fund. These expenses negatively impact the performance of the Fund. Also, market returns do not include brokerage commissions that may be payable on secondary market transactions. If brokerage commissions were included, market returns would be lower. The returns shown in the following table do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption or sale of Fund shares. The investment return and principal value of shares of the Fund will vary with changes in market conditions. Shares of the Fund may be worth more or less than their original cost when they are redeemed or sold in the market. The Fund’s past performance is no guarantee of future results.

The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

1 Year
3 Years
5 Years
10 Years
$49 $154 $269 $604

Portfolio Turnover. The Fund may pay transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 4% of the average value of its portfolio.

Principal Investment Strategies

The Underlying Index is a free float-adjusted market capitalization-weighted index designed to measure the combined equity market performance of the information technology sector of developed and emerging markets countries, excluding the United States. Component securities include those of software service, technology hardware and equipment service, information technology hardware, semiconductor and semiconductor equipment companies. As of September 30, 2011, the Underlying Index consisted of companies in the following countries or regions: Australia, Austria, Belgium, Brazil, Canada, Chile, China, Colombia, the Czech Republic, Denmark, Egypt, Finland, France, Germany, Greece, Hong Kong, Hungary, India, Indonesia, Ireland, Israel, Italy, Japan, Malaysia, Mexico, Morocco, the Netherlands, New Zealand, Norway, Peru, the Philippines, Poland, Portugal, Russia, Singapore, South Africa, South Korea, Spain, Sweden, Switzerland, Taiwan, Thailand, Turkey and the United Kingdom (together, the “ACWI ex US information technology sector countries”). As of September 30, 2011, the Underlying Index was comprised of 153 securities.

BFA uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to “beat” the index it tracks and does not seek temporary defensive positions when markets decline or appear overvalued.

Indexing may eliminate the chance that the Fund will substantially outperform the Underlying Index but also may reduce some of the risks of active management, such as poor security selection. Indexing seeks to achieve lower costs and better after-tax performance by keeping portfolio turnover low in comparison to actively managed investment companies.

BFA uses a representative sampling indexing strategy to manage the Fund. “Representative sampling” is an indexing strategy that involves investing in a representative sample of securities that collectively has an investment profile similar to the Underlying Index. The securities selected are expected to have, in the aggregate, investment characteristics (based on factors such as market capitalization and industry weightings), fundamental characteristics (such as return variability and yield) and liquidity measures similar to those of the Underlying Index. The Fund may or may not hold all of the securities in the Underlying Index.

The Fund generally invests at least 80% of its assets in securities of the Underlying Index or in depositary receipts representing securities of the Underlying Index. The Fund may invest the remainder of its assets in securities

S-2   


Table Of Contents



not included in the Underlying Index, but which BFA believes will help the Fund track the Underlying Index and in other investments including futures contracts, options on futures contracts, options and swaps related to the Underlying Index, as well as cash and cash equivalents, including shares of money market funds advised by BFA or its affiliates.

The Fund may lend securities representing up to one-third of the value of the Fund’s total assets (including the value of the collateral received).

The Underlying Index is sponsored by an organization (the “Index Provider”) that is independent of the Fund and BFA. The Index Provider determines the composition and relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index. The Fund’s Index Provider is MSCI Inc. (“MSCI”).

Industry Concentration Policy. The Fund will concentrate its investments (i.e., hold 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. For purposes of this limitation, securities of the U.S. government (including its agencies and instrumentalities) and repurchase agreements collateralized by U.S. government securities are not considered to be issued by members of any industry.

Summary of Principal Risks

As with any investment, you could lose all or part of your investment in the Fund, and the Fund’s performance could trail that of other investments. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund’s net asset value per share (“NAV”), trading price, yield, total return and ability to meet its investment objective.

Asset Class Risk. Securities in the Underlying Index or in the Fund’s portfolio may underperform in comparison to the general securities markets or other asset classes.

Concentration Risk. To the extent that the Fund’s investments are concentrated in a particular issuer, region, country, market, industry or asset class, the Fund may be susceptible to loss due to adverse occurrences affecting that issuer, region, country, market, industry or asset class.

Currency Risk. Because the Fund’s NAV is determined in U.S. dollars, the Fund’s NAV could decline if the currency of a non-U.S. market in which the Fund invests depreciates against the U.S. dollar.

Custody Risk. Less developed markets are more likely to experience problems with the clearing and settling of trades and the holding of securities by local banks, agents and depositories.

Emerging Markets Risk. The Fund’s investments in emerging markets may be subject to a greater risk of loss than investments in more developed markets. Emerging markets may be more likely to experience inflation risk, political turmoil and rapid changes in economic conditions than more developed markets. Emerging markets often have less uniformity in accounting and reporting requirements, unreliable securities valuation and greater risk associated with custody of securities.

Equity Securities Risk. Equity securities are subject to changes in value and their values may be more volatile than other asset classes.

Geographic Risk. A natural or other disaster could occur in a geographic region in which the Fund invests, which could affect the economy or particular business operations of companies in the specific geographic region, causing an adverse impact on the Fund’s investments in the affected region.

Information Technology Sector Risk. Information technology companies face intense competition and potentially rapid product obsolescence. They are also heavily dependent on intellectual property rights and may be adversely affected by loss or impairment of those rights.

Issuer Risk. Fund performance depends on the performance of individual securities to which the Fund has exposure. Changes to the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA’s investment management strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares, losses from trading in secondary markets, periods of high volatility and disruption in the creation/redemption process of the Fund. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV.

Non-Diversification Risk. The Fund may invest a large percentage of its assets in securities issued by or representing a small number of issuers. As a result, the Fund’s performance may depend on the performance of a small number of issuers.

Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers are subject to the risks associated with investing in those non-U.S. markets, such as heightened risks of inflation or nationalization. The Fund may lose money due to political, economic and geographic events affecting a non-U.S. issuer or market. The Fund is specifically exposed to Asian Economic Risk and European Economic Risk.

Passive Investment Risk. The Fund is not actively managed and BFA does not attempt to take defensive positions under any market conditions, including declining markets.

Privatization Risk. Some countries in which the Fund invests have begun a process of privatizing certain entities and industries. Privatized entities may lose money or be re-nationalized.

Reliance on Trading Partners Risk. The Fund invests in countries whose economies are heavily dependent upon trading with key partners. Any reduction in this trading may have an adverse impact on the Fund’s investments. Through its trading partners, the Fund is particularly exposed to U.S. Trading Partner Risk.

Risk of Investing in Japan. The Japanese economy may be subject to

S-4   


Table Of Contents



considerable degrees of economic, political and social instability, which could have a negative impact on Japanese securities.

Securities Lending Risk. The Fund may engage in securities lending. Securities lending involves the risk that the Fund may lose money because the borrower of the Fund’s loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Security Risk. Some countries and regions in which the Fund invests have experienced security concerns. Incidents involving a country’s or region’s security may cause uncertainty in these markets and may adversely affect their economies and the Fund’s investments.

Structural Risk. The countries in which the Fund invests may be subject to considerable degrees of economic, political and social instability.

Technology Sector Risk. The Fund may invest significantly in companies in the technology sector. Technology companies may have limited product lines, markets, financial resources or personnel. Technology companies typically face intense competition and potentially rapid product obsolescence. They are also heavily dependent on intellectual property rights and may be adversely affected by loss or impairment of those rights.

Tracking Error Risk. The performance of the Fund may diverge from that of the Underlying Index. Because the Fund employs a representative sampling strategy, the Fund may experience tracking error to a greater extent than a fund that seeks to replicate an index. BFA EXPECTS THAT THE FUND MAY EXPERIENCE HIGHER TRACKING ERROR THAN IS TYPICAL FOR SIMILAR INDEX EXCHANGE-TRADED FUNDS.

Valuation Risk. The value of the securities in the Fund’s portfolio may change on days when shareholders will not be able to purchase or sell the Fund’s shares.

Performance Information

As of the date of the Fund’s prospectus (the “Prospectus”), the Fund has been in operation for less than one full calendar year and therefore does not report its performance information.

Management

Investment Adviser. BlackRock Fund Advisors.

Portfolio Managers. Rene Casis, Diane Hsiung and Greg Savage (the “Portfolio Managers”) are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager supervises a portfolio management team. Mr. Casis has been a Portfolio Manager of the Fund since 2010. Ms. Hsiung and Mr. Savage have been Portfolio Managers of the Fund since inception.

Purchase and Sale of Fund Shares

The Fund is an exchange-traded fund (commonly referred to as an “ETF”). Individual Fund shares may only be purchased and sold on a national securities exchange through a broker-dealer. The price of Fund shares is based on market price, and because ETF shares trade at market prices rather than NAV, shares may trade at a price greater than NAV (a premium) or less than NAV (a discount). The Fund will only issue or redeem shares that have been aggregated into blocks of 50,000 shares or multiples thereof (“Creation Units”) to authorized participants who have entered into agreements with the Fund’s distributor. The Fund generally will issue or redeem Creation Units in return for a designated portfolio of securities (and an amount of cash) that the Fund specifies each day.

Tax Information

The Fund intends to make distributions that may be taxable to you as ordinary income or capital gains, unless you are investing through a tax-deferred arrangement such as a 401(k) plan or an individual retirement account (“IRA”).

Payments to Broker-Dealers and other Financial Intermediaries

If you purchase shares of the Fund through a broker-dealer or other financial intermediary (such as a bank), BFA or other related companies may pay the intermediary for marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems or other services related to the sale or promotion of the Fund. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.

More Information About the Fund

This Prospectus contains important information about investing in the Fund. Please read this Prospectus carefully before you make any investment decisions. Additional information regarding the Fund is available at www.iShares.com.

BFA is the investment adviser to the Fund. Shares of the Fund are listed for trading on NYSE Arca, Inc. (“NYSE Arca”). The market price for a share of the Fund may be different from the Fund’s most recent NAV.

ETFs are funds that trade like other publicly-traded securities. The Fund is designed to track an index. Similar to shares of an index mutual fund, each share of the Fund represents a partial ownership in an underlying portfolio of securities intended to track a market index. Unlike shares of a mutual fund, which can be bought and redeemed from the issuing fund by all shareholders at a price based on NAV, shares of the Fund may be purchased or redeemed directly from the Fund at NAV solely by authorized participants. Also unlike shares of a mutual fund, shares of the Fund are listed on a national securities exchange and trade in the secondary market at market prices that change throughout the day.

The Fund invests in a particular segment of the securities markets and seeks to track the performance of a securities index that generally is not representative of the market as a whole. The Fund is designed to be used as part of broader asset allocation strategies. Accordingly, an investment in the Fund should not constitute a complete investment program.

An index is a theoretical financial calculation while the Fund is an actual investment portfolio. The performance of the Fund and the Underlying Index may vary due to transaction costs, non-U.S. currency valuations, asset valuations, corporate actions (such as mergers and spin-offs), timing variances and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions (such as diversification requirements) that apply to the Fund but not to the Underlying Index or to the use of representative sampling. “Tracking error” is the difference between the performance (return) of the Fund’s portfolio and that of the Underlying Index. BFA expects that, over time, the Fund’s tracking error will not exceed 5%. Because the Fund uses a representative sampling indexing strategy, it can be expected to have a larger tracking error than if it used a replication indexing strategy. “Replication” is an indexing strategy in which a fund invests in substantially all of the securities in its underlying index in approximately the same proportions as in the underlying index.

An investment in the Fund is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, BFA or any of its affiliates.

The Fund’s investment objective and the Underlying Index may be changed without shareholder approval.

A Further Discussion of Principal Risks

The Fund is subject to various risks, including the principal risks noted below, any of which may adversely affect the Fund’s NAV, trading price, yield, total return and ability to meet its investment objective. You could lose all or part of your investment in the Fund, and the Fund could underperform other investments.

Asian Economic Risk. Certain Asian economies have experienced over-extension of credit, currency devaluations and restrictions, high unemployment, high inflation, decreased exports and economic recessions. Economic events in any one Asian country may have a significant economic effect on the entire Asian region, as well as on major trading partners outside Asia, and any adverse event in the Asian markets may have a significant adverse effect on some or all of the ACWI ex US information technology sector countries.

Asset Class Risk. The securities in the Underlying Index or in the Fund’s portfolio may underperform the returns of other securities or indexes that track other countries, groups of countries, regions, industries, groups of industries, markets, asset classes or sectors. Various types of securities or indexes tend to experience cycles of outperformance and underperformance in comparison to the general securities markets.

Concentration Risk. To the extent that the Fund’s portfolio reflects the Underlying Index’s concentration in the securities of a particular issuer or issuers in a particular country, group of countries, region, market, industry, group of industries, sector or asset class, the Fund may be adversely affected by the performance of those securities, may be subject to increased price volatility and may be more susceptible to adverse economic, market, political or regulatory occurrences affecting that issuer, country, group of countries, region, market, industry, group of industries, sector or asset class.

Currency Risk. Because the Fund’s NAV is determined on the basis of the U.S. dollar, investors may lose money if the currency of a non-U.S. market in which the Fund invests depreciates against the U.S. dollar, even if the local currency value of the Fund’s holdings in that market increases.



Custody Risk. Custody risk refers to the risks inherent in the process of clearing and settling trades and the holding of securities by local banks, agents and depositories. Low trading volumes and volatile prices in less developed markets may make trades harder to complete and settle, and governments or trade groups may compel local agents to hold securities in designated depositories that are not subject to independent evaluation. Local agents are held only to the standards of care of their local markets. In general, the less developed a country’s securities market is, the greater the likelihood of custody problems.

Emerging Markets Risk. Investments in emerging markets are subject to a greater risk of loss than investments in more developed markets. This is due to, among other things, the potential for greater market volatility, lower trading volume, inflation, political and economic instability, greater risk of a market shutdown and more governmental limitations on foreign investments than typically found in more developed markets. In addition, emerging markets often have less uniformity in

accounting and reporting requirements, unreliable securities valuation and greater risks associated with custody of securities.

Equity Securities Risk. The Fund invests in equity securities, which are subject to changes in value that may be attributable to market perception of a particular issuer or to general stock market fluctuations that affect all issuers. Investments in equity securities may be more volatile than investments in other asset classes.

European Economic Risk. The Economic and Monetary Union of the European Union (the “EU”) requires member countries to comply with restrictions on inflation rates, deficits, interest rates, debt levels and fiscal and monetary controls, each of which may significantly affect every country in Europe. Decreasing imports or exports, changes in governmental or EU regulations on trade, changes in the exchange rate of the euro, the default or threat of default by an EU member country on its sovereign debt, and/or an economic recession in an EU member country may have a significant adverse effect on the economies of EU member countries and their trading partners, including some or all of the ACWI ex US information technology sector countries. The European financial markets have recently experienced volatility and have been adversely affected by concerns about economic downturns, credit rating downgrades, rising government debt levels and possible default on or restructuring of government debt in several European countries, including Greece, Ireland, Italy, Portugal and Spain. A default or debt restructuring by any European country would adversely impact holders of that country’s debt, and sellers of credit default swaps linked to that country’s creditworthiness, which may be located in countries other than those listed in the previous sentence. These events have adversely affected the value and exchange rate of the euro and may continue to significantly affect the economies of every country in Europe, including EU member countries that do not use the euro and non-EU member countries.

Geographic Risk. Some markets in which the Fund invests are located in parts of the world that have historically been prone to natural disasters, such as earthquakes, volcanoes, droughts, floods, hurricanes and tsunamis, and are economically sensitive to environmental events. Any natural or other disaster could have a significant adverse impact on the economies of these geographic areas, causing an adverse impact on the Fund’s investments in the affected region.

Information Technology Sector Risk. Information technology companies face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Like other technology companies, information technology companies may have limited product lines, markets, financial resources or personnel. The products of information technology companies may face obsolescence due to rapid technological developments and frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Companies in the information technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies.

Issuer Risk. The performance of the Fund depends on the performance of individual securities to which the Fund has exposure. Any issuer of these securities may perform poorly, causing the value of its securities to decline. Poor performance may be caused

by poor management decisions, competitive pressures, changes in technology, expiration of patent protection, disruptions in supply, labor problems or shortages, corporate restructurings, fraudulent disclosures or other factors. Issuers may, in times of distress or at their own discretion, decide to reduce or eliminate dividends, which may also cause their stock prices to decline.

Management Risk. The Fund may not fully replicate the Underlying Index and may hold securities not included in the Underlying Index. As a result, the Fund is subject to the risk that BFA’s investment management strategy, the implementation of which is subject to a number of constraints, may not produce the intended results.

Market Risk. The Fund could lose money due to short-term market movements and over longer periods during market downturns. Securities may decline in value due to factors affecting securities markets generally or particular industries represented in the markets. The value of a security may decline due to general market conditions, economic trends or events that are not specifically related to the issuer of the security or to factors that affect a particular industry or industries. During a general downturn in the securities markets, multiple asset classes may be negatively affected.

Market Trading Risk

Absence of Active Market. Although shares of the Fund are listed for trading on one or more stock exchanges, there can be no assurance that an active trading market for such shares will develop or be maintained.

Risk of Secondary Listings. The Fund’s shares may be listed or traded on U.S. and non-U.S. stock exchanges other than the U.S. stock exchange where the Fund’s primary listing is maintained. There can be no assurance that the Fund’s shares will continue to trade on any such stock exchange or in any market or that the Fund’s shares will continue to meet the requirements for listing or trading on any exchange or in any market. The Fund’s shares may be less actively traded in certain markets than others, and investors are subject to the execution and settlement risks and market standards of the market where they or their broker direct their trades for execution. Certain information available to investors who trade Fund shares on a U.S. stock exchange during regular U.S. market hours may not be available to investors who trade in other markets, which may result in secondary market prices in such markets being less efficient.

Secondary Market Trading Risk. Shares of the Fund may trade in the secondary market at times when the Fund does not accept orders to purchase or redeem shares. At such times, shares may trade in the secondary market with more significant premiums or discounts than might be experienced at times when the Fund accepts purchase and redemption orders.

Secondary market trading in Fund shares may be halted by a stock exchange because of market conditions or other reasons. In addition, trading in Fund shares on a stock exchange or in any market may be subject to trading halts caused by extraordinary market volatility pursuant to “circuit breaker” rules on the stock exchange or market. There can be no assurance that the requirements necessary to maintain the listing or trading of Fund shares will continue to be met or will remain unchanged.

Shares of the Fund May Trade at Prices Other Than NAV. Shares of the Fund trade on stock exchanges at prices at, above or below their most recent NAV. The NAV of the Fund is calculated at the end of each business day and fluctuates with changes in the market value of the Fund’s holdings since the most recent calculation. The trading prices of the Fund’s shares fluctuate continuously throughout trading hours based on market supply and demand rather than NAV. The trading prices of the Fund’s shares may deviate significantly from NAV during periods of market volatility. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV. However, because shares can be created and redeemed in Creation Units at NAV (unlike shares of many closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their NAVs), BFA believes that large discounts or premiums to the NAV of the Fund are not likely to be sustained over the long-term. While the creation/redemption feature is designed to make it likely that the Fund’s shares normally will trade on stock exchanges at prices close to the Fund’s next calculated NAV, exchange prices are not expected to correlate exactly with the Fund’s NAV due to timing reasons as well as market supply and demand factors. In addition, disruptions to creations and redemptions or extreme market volatility may result in trading prices for shares of the Fund that differ significantly from its NAV.

Costs of Buying or Selling Fund Shares. Buying or selling Fund shares on an exchange involves two types of costs that apply to all securities transactions. When buying or selling shares of the Fund through a broker, you will likely incur a brokerage commission or other charges imposed by brokers as determined by that broker. In addition, you may incur the cost of the “spread” – that is, the difference between what investors are willing to pay for Fund shares (the “bid” price) and the price at which they are willing to sell Fund shares (the “ask” price). Because of the costs inherent in buying or selling Fund shares, frequent trading may detract significantly from investment results and an investment in Fund shares may not be advisable for investors who anticipate regularly making small investments.

Non-Diversification Risk. The Fund is classified as “non-diversified.” This means that the Fund may invest a large percentage of its assets in securities issued by or representing a small number of issuers. As a result, the Fund may be more susceptible to the risks associated with these particular issuers, or to a single economic, political or regulatory occurrence affecting these issuers.

Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers are subject to all of the risks of investing in the markets where such issuers are located, including heightened risks of inflation or nationalization and market fluctuations caused by economic and political developments. As a result of investing in non-U.S. securities, the Fund may be subject to increased risk of loss caused by any of the factors listed below:

  • Lower levels of liquidity and market efficiency;
  • Greater securities price volatility;
  • Exchange rate fluctuations and exchange controls;
  • Less availability of public information about issuers;
  • Limitations on foreign ownership of securities;
  • Imposition of withholding or other taxes;
  • Imposition of restrictions on the expatriation of the funds or other assets of the Fund;
  • Higher transaction and custody costs and delays in settlement procedures;
  • Difficulties in enforcing contractual obligations;
  • Lower levels of regulation of the securities market;
  • Weaker accounting, disclosure and reporting requirements; and
  • Legal principles related to corporate governance, directors’ fiduciary duties and liabilities and stockholders’ rights in markets in which the Fund invests may differ and/or may not be as extensive or protective as those that apply in the United States.

Passive Investment Risk. The Fund is not actively managed and may be affected by a general decline in market segments related to the Underlying Index. The Fund invests in securities included in, or representative of, the Underlying Index regardless of their investment merits. BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

Privatization Risk. Some countries in which the Fund invests have begun a process of privatizing certain entities and industries. In some instances, investors in newly privatized entities have suffered losses due to the inability of the newly privatized entities to adjust quickly to a competitive environment or changing regulatory and legal standards or, in some cases, due to re-nationalization of such privatized entities. There is no assurance that such losses will not recur.

Reliance on Trading Partners Risk. The economies of the ACWI ex US information technology sector countries are dependent on each other and on the United States as key trading partners. Reduction in spending on the products and services of the ACWI ex US information technology sector countries by any of their key trading partners, institution of tariffs or other trade barriers or a slowdown in the economies of any of their key trading partners may cause an adverse impact on the economies of the ACWI ex US information technology sector countries.

U.S. Trading Partners Risk. The United States is a significant, and in some cases the most significant, trading partner of or foreign investor in certain ACWI ex US information technology sector countries and the economies of these countries may be particularly affected by changes in the U.S. economy. Decreasing U.S. imports, new trade regulations, changes in the U.S. dollar exchange rate or a recession in the United States may have a material adverse effect on the economies of ACWI ex US information technology sector countries.

Risk of Investing in Japan. Japan may be subject to political, economic, nuclear, and labor risks. Any of these risks, individually or in the aggregate, can impact an investment made in Japan.

  • Political Risk. Historically, Japan has had unpredictable national politics and may experience frequent political turnover. Future political developments may lead to changes in policy that might adversely affect the Fund’s investments.
  • Large Government Debt Risk. The Japanese economy faces several concerns, including a financial system with large levels of nonperforming loans, over-leveraged corporate balance sheets, extensive cross-ownership by major corporations, a changing corporate governance structure, and large government deficits. These issues may cause a slowdown of the Japanese economy.
  • Currency Risk. The Japanese yen has fluctuated widely at times and any increase in its value may cause a decline in exports that could weaken the economy.
  • Nuclear Risk. The nuclear power plant catastrophe in Japan in March of 2011 may have short-term and long-term effects on the nuclear energy industry, the extent of which are currently unknown.
  • Labor Risk. Japan has an aging workforce. It is a labor market that is undergoing fundamental structural changes, as traditional lifetime employment clashes with the need for increased labor mobility, which may adversely affect Japan’s economic competitiveness.
  • Geographic Risk. Natural disasters, such as earthquakes, could occur in Japan or surrounding areas and could negatively affect the Japanese economy, and, in turn, could negatively affect the Fund.

Securities Lending Risk. The Fund may engage in securities lending. Securities lending involves the risk that the Fund may lose money because the borrower of the Fund’s loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for the loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Security Risk. Some geographic areas in which the Fund invests have experienced acts of terrorism or strained international relations due to territorial disputes, historical animosities or other defense concerns. These situations may cause uncertainty in the markets of these geographic areas and may adversely affect the performance of their economies.

Structural Risk. Certain political, economic, legal and currency risks have contributed to a high degree of price volatility in the equity markets of the ACWI ex US information technology sector countries and could adversely affect investments in the Fund:

Political and Social Risk. Disparities of wealth, the pace and success of democratization and ethnic, religious and racial disaffection, among other factors, have led to social unrest, violence and labor unrest in some ACWI ex US information technology sector countries. Unanticipated or sudden political or social developments may result in sudden and significant investment losses.

Economic Risk. Some ACWI ex US information technology sector countries may experience economic instability, including instability resulting from substantial rates of inflation or significant devaluations of their currency, or economic recessions causing a negative effect on the economies and securities markets of their economies. Some of these countries may also impose restrictions on the exchange or export of currency or adverse currency exchange rates and may be characterized by a lack of available currency hedging instruments.

Expropriation and/or Nationalization Risk. Investments in certain ACWI ex US information technology sector countries may be subject to loss due to expropriation or nationalization of assets and property or the imposition of restrictions on foreign investments and repatriation of capital.

Large Government Debt Risk. Chronic structural public sector deficits in some ACWI ex US information technology sector countries may adversely impact investments in the Fund.

Technology Sector Risk. The Fund invests in technology companies, which face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Technology companies may have limited product lines, markets, financial resources or personnel. The products of technology companies may face obsolescence due to rapid technological developments and frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Companies in the technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies. The technology sector may also be adversely affected by changes or trends in commodity prices, which may be influenced or characterized by unpredictable factors.

Tracking Error Risk. Imperfect correlation between the Fund’s portfolio securities and those in the Underlying Index, rounding of prices, changes to the Underlying Index and regulatory requirements may cause tracking error, which is the divergence of the Fund’s performance from that of the Underlying Index. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Underlying Index does not. Because the Fund employs a representative sampling strategy, the Fund may experience tracking error to a greater extent than a fund that seeks to replicate an index. BFA EXPECTS THAT THE FUND MAY EXPERIENCE HIGHER TRACKING ERROR THAN IS TYPICAL FOR SIMILAR INDEX ETFS.

Valuation Risk. Because non-U.S. exchanges may be open on days when the Fund does not price its shares, the value of the securities in the Fund’s portfolio may change on days when shareholders will not be able to purchase or sell the Fund’s shares. In addition, for purposes of calculating the Fund’s NAV, the value of assets denominated in non-U.S. currencies is converted into U.S. dollars using exchange rates deemed appropriate by BFA. This conversion may result in a difference between the prices used to calculate the Fund’s NAV and the prices used by the Underlying Index, which, in turn, could result in a difference between the Fund’s performance and the performance of the Underlying Index.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

Mid-Capitalization Companies Risk. Many of the companies in which the Fund invests are considered mid-capitalization companies. Stock prices of mid-capitalization companies may be more volatile than those of large-capitalization companies and,

therefore, the Fund’s share price may be more volatile than those of funds that invest a larger percentage of their assets in stocks issued by large-capitalization companies. Stock prices of mid-capitalization companies are also more vulnerable than those of large-capitalization companies to adverse business or economic developments, and the stocks of mid-capitalization companies may be less liquid, making it difficult for the Fund to buy and sell them. In addition, mid-capitalization companies generally have less diverse product lines than large-capitalization companies and are more susceptible to adverse developments related to their products.

Small-Capitalization Companies Risk. Many of the companies in which the Fund invests are considered small-capitalization companies. Stock prices of small-capitalization companies may be more volatile than those of larger companies and, therefore, the Fund’s share price may be more volatile than those of funds that invest a larger percentage of their assets in stocks issued by mid- or large-capitalization companies. Stock prices of small-capitalization companies are generally more vulnerable than those of mid- or large-capitalization companies to adverse business and economic developments. Securities of small-capitalization companies may be thinly traded, making it difficult for the Fund to buy and sell them. In addition, small-capitalization companies are typically less financially stable than larger, more established companies and may depend on a small number of essential personnel, making them more vulnerable to loss of personnel. Small-capitalization companies also normally have less diverse product lines than mid- or large-capitalization companies and are more susceptible to adverse developments concerning their products.

Management

Investment Adviser. As investment adviser, BFA has overall responsibility for the general management and administration of the Trust. BFA provides an investment program for the Fund and manages the investment of the Fund’s assets. In managing the Fund, BFA may draw upon the research and expertise of its asset management affiliates with respect to certain portfolio securities. In seeking to achieve the Fund’s investment objective, BFA uses teams of portfolio managers, investment strategists and other investment specialists. This team approach brings together many disciplines and leverages BFA’s extensive resources.

Pursuant to the Investment Advisory Agreement between BFA and the Trust (entered into on behalf of the Fund), BFA is responsible for substantially all expenses of the Fund, except interest expenses, taxes, brokerage expenses, future distribution fees or expenses and extraordinary expenses.

For its investment advisory services to the Fund, BFA is entitled to receive a management fee from the Fund based on a percentage of the Fund’s average daily net assets, at the annual rate of 0.48%.

BFA is located at 400 Howard Street, San Francisco, CA 94105. It is a wholly owned subsidiary of BTC, which in turn is indirectly wholly-owned by BlackRock, Inc. (“BlackRock”). As of September 30, 2011, BTC and its affiliates, including BFA and BlackRock, provided investment advisory services for assets in excess of $3.35 trillion. BFA, BTC, BlackRock Execution Services, BlackRock and their affiliates deal, trade and invest for their own accounts in the types of securities in which the Fund may also invest.

A discussion regarding the basis for the Trust’s Board of Trustees’ (the “Board”) approval of the Investment Advisory Agreement with BFA is available in the Fund’s annual report for the period ended July 31.

Portfolio Managers. Rene Casis, Diane Hsiung and Greg Savage are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager is responsible for various functions related to portfolio management, including, but not limited to, investing cash inflows, coordinating with members of his or her portfolio management team to focus on certain asset classes, implementing investment strategy, researching and reviewing investment strategy and overseeing members of his or her portfolio management team that have more limited responsibilities.

Rene Casis has been employed by BFA (formerly, Barclays Global Fund Advisors (“BGFA”)) and BTC (formerly, Barclays Global Investors, N.A. (“BGI”)) as a senior portfolio manager since 2009. From 2005 to 2009, Mr. Casis was a trader at Barclays Capital. Prior to that, Mr. Casis was a portfolio manager from 2000 to 2005 for BGFA and BGI. Mr. Casis has been a Portfolio Manager of the Fund since 2010.

Diane Hsiung has been employed by BFA and BTC as a senior portfolio manager since 2007. Prior to that, Ms. Hsiung was a portfolio manager from 2002 to 2006 for BGFA and BGI. Ms. Hsiung has been a Portfolio Manager of the Fund since inception.

Greg Savage has been employed by BFA and BTC as a senior portfolio manager since 2006. Prior to that, Mr. Savage was a portfolio manager from 2001 to 2006 for BGFA and BGI. Mr. Savage has been a Portfolio Manager of the Fund since inception.

The Fund’s SAI provides additional information about the Portfolio Managers’ compensation, other accounts managed by the Portfolio Managers and the Portfolio Managers’ ownership (if any) of shares in the Fund.

Administrator, Custodian and Transfer Agent. State Street Bank and Trust Company (“State Street”) is the administrator, custodian and transfer agent for the Fund.

Conflicts of Interest. BFA wants you to know that there are certain entities with which BFA has relationships that may give rise to conflicts of interest, or the appearance of conflicts of interest. These entities include the following: BFA’s affiliates (including BlackRock and The PNC Financial Services Group, Inc., and each of their affiliates, directors, partners, trustees, managing members, officers and employees

(collectively, the “Affiliates”)) and BlackRock’s significant shareholder, Barclays Bank PLC and its affiliates, including Barclays PLC (each, an “Entity” and together, the “Entities”).

The activities of BFA, the Affiliates and the Entities in the management of, or their interest in, their own accounts and other accounts they manage, may present conflicts of interest that could disadvantage the Fund and the shareholders. BFA and its Affiliates or the Entities provide investment management services to other funds and discretionary managed accounts that may follow an investment program similar to that of the Fund. BFA, its Affiliates and the Entities are involved worldwide with a broad spectrum of financial services and asset management activities and may engage in the ordinary course of business in activities in which their interests or the interests of their clients may conflict with those of the Fund. BFA, one or more of the Affiliates or the Entities acts, or may act, as an investor, investment banker, research provider, investment manager, financier, underwriter, advisor, market maker, trader, prime broker, lender, agent or principal, and have other direct and indirect interests, in securities, currencies and other instruments in which the Fund may directly or indirectly invest. Thus, it is likely that the Fund will have multiple business relationships with and will invest in, engage in transactions with, make voting decisions with respect to, or obtain services from, entities for which BFA, an Affiliate or an Entity performs or seeks to perform investment banking or other services.

BFA or one or more Affiliates or Entities may engage in proprietary trading and advise accounts and funds that have investment objectives similar to those of the Fund and/or that engage in and compete for transactions in the same types of securities, currencies and other instruments as the Fund, including in securities issued by other open-end and closed-end investment management companies, including investment companies that are affiliated with the Fund and BFA, to the extent permitted under the Investment Company Act of 1940, as amended (the “1940 Act”). The trading activities of BFA, these Affiliates and Entities are carried out without reference to positions held directly or indirectly by the Fund and may result in BFA, an Affiliate or an Entity having positions that are adverse to those of the Fund.

No Affiliate or Entity is under any obligation to share any investment opportunity, idea or strategy with the Fund. As a result, an Affiliate or an Entity may compete with the Fund for appropriate investment opportunities. As a result of this and several other factors, the results of the Fund’s investment activities may differ from those of an Affiliate or an Entity and of other accounts managed by an Affiliate or an Entity, and it is possible that the Fund could sustain losses during periods in which one or more Affiliates or Entities and other accounts achieve profits on their trading for proprietary or other accounts. The opposite result is also possible.

The Fund may, from time to time, enter into transactions in which BFA or an Affiliate’s or an Entity’s clients have an interest adverse to the Fund. Furthermore, transactions undertaken by Affiliate-advised clients may adversely impact the Fund. Transactions by one or more Affiliate- or Entity-advised clients or BFA may have the effect of diluting or otherwise disadvantaging the values, prices or investment strategies of the Fund.

An Entity may maintain securities indices as part of the product offerings. Index-based funds seek to track the performance of securities indices and may use the name of the

index in the fund name. Index providers, including the Entities, may be paid licensing fees for use of their indices or index names. Entities will not be obligated to license their indices to BFA and its Affiliates, and BFA and its Affiliates will not be assured that the terms of any index licensing agreement with the Entities will be as favorable as those terms offered to other index licensees.

The Fund’s activities may be limited because of regulatory restrictions applicable to one or more Affiliates or Entities, and/or their internal policies designed to comply with such restrictions. In addition, the Fund may invest in securities of companies with which an Affiliate or an Entity has or is trying to develop investment banking relationships or in which an Affiliate or an Entity has significant debt or equity investments. The Fund also may invest in securities of companies for which an Affiliate or an Entity provides or may some day provide research coverage. An Affiliate or an Entity may have business relationships with and purchase or distribute or sell services or products from or to distributors, consultants or others who recommend the Fund or who engage in transactions with or for the Fund, and may receive compensation for such services. The Fund may also make brokerage and other payments to Affiliates or Entities in connection with the Fund’s portfolio investment transactions.

Pursuant to a securities lending program approved by the Board, the Fund has retained an Affiliate of BFA to serve as the securities lending agent for the Fund to the extent that the Fund participates in the securities lending program. For these services, the lending agent may receive a fee from the Fund, including a fee based on the returns earned on the Fund’s investment of the cash received as collateral for any loaned securities. In addition, one or more Affiliates may be among the entities to which the Fund may lend its portfolio securities under the securities lending program.

The activities of BFA, the Affiliates or Entities may give rise to other conflicts of interest that could disadvantage the Fund and the shareholders. BFA has adopted policies and procedures designed to address these potential conflicts of interest. See the Fund’s SAI for further information.

Shareholder Information

Additional shareholder information, including how to buy and sell shares of the Fund, is available free of charge by calling toll-free: 1-800-iShares (1-800-474-2737) or visiting our website at www.iShares.com.

Buying and Selling Shares. Shares of the Fund may be acquired or redeemed directly from the Fund only in Creation Units or multiples thereof, as discussed in the Creations and Redemptions section of this Prospectus. Only an Authorized Participant (as defined in the Creations and Redemptions section) may engage in creation or redemption transactions directly with the Fund. Once created, shares of the Fund generally trade in the secondary market in amounts less than a Creation Unit.

Shares of the Fund are listed on a national securities exchange for trading during the trading day. Shares can be bought and sold throughout the trading day like shares of other publicly-traded companies. The Trust does not impose any minimum investment for shares of the Fund purchased on an exchange. The Fund’s shares trade under the trading symbol “AXIT.”

Buying or selling Fund shares on an exchange involves two types of costs that may apply to all securities transactions. When buying or selling shares of the Fund through a broker, you will likely incur a brokerage commission or other charges determined by your broker. The commission is frequently a fixed amount and may be a significant proportional cost for investors seeking to buy or sell small amounts of shares. In addition, you may incur the cost of the “spread” – that is, any difference between the bid price and the ask price. The spread varies over time for shares of the Fund based on the trading volume and market liquidity, and is generally lower if the Fund has a lot of trading volume and market liquidity, and higher if the Fund has little trading volume and market liquidity.

The Board has adopted a policy of not monitoring for frequent purchases and redemptions of Fund shares (“frequent trading”) that appear to attempt to take advantage of a potential arbitrage opportunity presented by a lag between a change in the value of the Fund’s portfolio securities after the close of the primary markets for the Fund’s portfolio securities and the reflection of that change in the Fund’s NAV (“market timing”), because the Fund generally sells and redeems its shares directly through transactions that are in-kind and/or for cash, subject to the conditions described below under Creations and Redemptions. The Board has not adopted a policy of monitoring for other frequent trading activity because shares of the Fund are listed for trading on a national securities exchange.

The national securities exchange on which the Fund’s shares are listed is open for trading Monday through Friday and is closed on weekends and the following holidays: New Year’s Day, Martin Luther King, Jr. Day, Presidents’ Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day. The Fund’s primary listing exchange is NYSE Arca.

Section 12(d)(1) of the 1940 Act restricts investments by investment companies in the securities of other investment companies. Registered investment companies are permitted to invest in the Fund beyond the limits set forth in Section 12(d)(1), subject to certain terms and conditions set forth in SEC rules or in an SEC exemptive order issued to the Trust. In order for a registered investment company to invest in shares of the Fund beyond the limitations of Section 12(d)(1) pursuant to the exemptive relief obtained by the Trust, the registered investment company must enter into an agreement with the Trust.

Book Entry. Shares of the Fund are held in book-entry form, which means that no stock certificates are issued. The Depository Trust Company (“DTC”) or its nominee is the record owner of all outstanding shares of the Fund and is recognized as the owner of all shares for all purposes.

Investors owning shares of the Fund are beneficial owners as shown on the records of DTC or its participants. DTC serves as the securities depository for shares of the Fund. DTC participants include securities brokers and dealers, banks, trust companies, clearing corporations and other institutions that directly or indirectly maintain a custodial relationship with DTC. As a beneficial owner of shares, you are not entitled to receive physical delivery of stock certificates or to have shares registered in your name, and you are not considered a registered owner of shares. Therefore, to exercise any right as an owner of shares, you must rely upon the procedures of DTC and its

participants. These procedures are the same as those that apply to any other securities that you hold in book-entry or “street name” form.

Share Prices. The trading prices of the Fund’s shares in the secondary market generally differ from the Fund’s daily NAV and are affected by market forces such as supply and demand, economic conditions and other factors. Information regarding the intraday value of shares of the Fund, also known as the “indicative optimized portfolio value” (“IOPV”), is disseminated every 15 seconds throughout the trading day by the national securities exchange on which the Fund’s shares are listed or by market data vendors or other information providers. The IOPV is based on the current market value of the securities and/or cash required to be deposited in exchange for a Creation Unit. The IOPV does not necessarily reflect the precise composition of the current portfolio of securities held by the Fund at a particular point in time or the best possible valuation of the current portfolio. Therefore, the IOPV should not be viewed as a “real-time” update of the Fund’s NAV, which is computed only once a day. The IOPV is generally determined by using both current market quotations and/or price quotations obtained from broker-dealers that may trade in the portfolio securities held by the Fund. The quotations of certain Fund holdings may not be updated during U.S. trading hours if such holdings do not trade in the United States. The Fund is not involved in, or responsible for, the calculation or dissemination of the IOPV and makes no representation or warranty as to its accuracy.

Determination of Net Asset Value. The NAV of the Fund normally is determined once daily Monday through Friday, generally as of the regularly scheduled close of business of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m., Eastern time) on each day that the NYSE is open for trading, based on prices at the time of closing provided that (a) any Fund assets or liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers (as detailed below) and (b) U.S. fixed income assets may be valued as of the announced closing time for trading in fixed income instruments in a particular market or exchange. The NAV of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets held by the Fund, and its liabilities, are determined pursuant to valuation policies and procedures approved by the Board. The Fund’s assets and liabilities are valued primarily on the basis of market quotations.

Equity investments are valued at market value, which is generally determined using the last reported official closing price or last trading price on the exchange or market on which the security is primarily traded at the time of valuation.

The Fund invests in foreign securities. Foreign currency exchange rates are generally determined as of 4:00 p.m., London time. Foreign securities owned by the Fund may trade on weekends or other days when the Fund does not price its shares. As a result, the Fund’s NAV may change on days when Authorized Participants will not be able to purchase or redeem Fund shares.

Generally, trading in foreign securities, U.S. government securities, money market instruments and certain fixed-income securities is substantially completed each day at various times prior to the close of business on the NYSE. The values of such securities used in computing the NAV of the Fund are determined as of such times.

When market quotations are not readily available or are believed by BFA to be unreliable, the Fund’s investments are valued at fair value. Fair value determinations are made by BFA in accordance with policies and procedures approved by the Fund’s Board. BFA may conclude that a market quotation is not readily available or is unreliable if a security or other asset or liability does not have a price source due to its lack of liquidity, if a market quotation differs significantly from recent price quotations or otherwise no longer appears to reflect fair value, where the security or other asset or liability is thinly traded, or where there is a significant event subsequent to the most recent market quotation. A “significant event” is an event that, in the judgment of BFA, is likely to cause a material change to the closing market price of the asset or liability held by the Fund. Foreign securities whose values are affected by volatility that occurs in U.S. markets on a trading day after the close of foreign securities markets may be fair valued.

Fair value represents a good faith approximation of the value of an asset or liability. The fair value of an asset or liability held by the Fund is the amount the Fund might reasonably expect to receive from the current sale of that asset or the cost to extinguish that liability in an arm’s-length transaction. Valuing the Fund’s investments using fair value pricing will result in prices that may differ from current market valuations and that may not be the price at which those investments could have been sold during the period in which the particular fair values were used. Use of fair value prices and certain current market valuations could result in a difference between the prices used to calculate the Fund’s NAV and the prices used by the Underlying Index, which, in turn, could result in a difference between the Fund’s performance and the performance of the Underlying Index.

The value of assets or liabilities denominated in non-U.S. currencies will be converted into U.S. dollars using exchange rates deemed appropriate by BFA as investment adviser. Use of a rate different from the rate used by the Index Provider may adversely affect the Fund’s ability to track the Underlying Index.

Dividends and Distributions

General Policies. Dividends from net investment income, if any, generally are declared and paid semi-annually by the Fund. Distributions of net realized securities gains, if any, generally are declared and paid once a year, but the Trust may make distributions on a more frequent basis for the Fund. The Trust reserves the right to declare special distributions if, in its reasonable discretion, such action is necessary or advisable to preserve its status as a regulated investment company (“RIC”) or to avoid imposition of income or excise taxes on undistributed income or realized gains.

Dividends and other distributions on shares of the Fund are distributed on a pro rata basis to beneficial owners of such shares. Dividend payments are made through DTC participants and indirect participants to beneficial owners then of record with proceeds received from the Fund.

Dividend Reinvestment Service. No dividend reinvestment service is provided by the Trust. Broker-dealers may make available the DTC book-entry Dividend Reinvestment Service for use by beneficial owners of the Fund for reinvestment of their dividend distributions. Beneficial owners should contact their broker to determine the availability and costs of the service and the details of participation therein. Brokers may require beneficial owners to adhere to specific procedures and timetables. If this service is available and used, dividend distributions of both income and realized gains will be automatically reinvested in additional whole shares of the Fund purchased in the secondary market.

Taxes. As with any investment, you should consider how your investment in shares of the Fund will be taxed. The tax information in this Prospectus is provided as general information, based on current law. You should consult your own tax professional about the tax consequences of an investment in shares of the Fund.

Unless your investment in Fund shares is made through a tax-exempt entity or tax-deferred retirement account, such as an IRA, you need to be aware of the possible tax consequences when the Fund makes distributions or you sell Fund shares.

Taxes on Distributions. Distributions from the Fund’s net investment income (other than qualified dividend income), including distributions of income from securities lending and distributions out of the Fund’s net short-term capital gains, if any, are taxable to you as ordinary income. Distributions by the Fund of net long-term capital gains in excess of net short-term capital losses (capital gain dividends) are taxable to you as long-term capital gains, generally at a 15% tax rate (0% at certain income levels), regardless of how long you have held the Fund’s shares. Distributions by the Fund that qualify as qualified dividend income are taxable to you at long-term capital gain rates for taxable years beginning on or before December 31, 2012. The 15% and 0% tax rates expire for taxable years beginning after December 31, 2012. Maximum long-term capital gain income tax rates are scheduled to rise to 20% in 2013. Beginning in 2013, a 3.8% U.S. federal Medicare contribution tax will be imposed on “net investment income,” including interest, dividends, and capital gains, of U.S. individuals with income exceeding $200,000 (or $250,000 if married and filing jointly), and of estates and trusts.

Dividends will be qualified dividend income to you if they are attributable to qualified dividend income received by the Fund. Generally, qualified dividend income includes dividend income from taxable U.S. corporations and qualified non-U.S. corporations, provided that the Fund satisfies certain holding period requirements in respect of the stock of such corporations and has not hedged its position in the stock in certain ways. Substitute dividends received by the Fund with respect to dividends paid on securities lent out will not be qualified dividend income. For this purpose, a qualified non-U.S. corporation means any non-U.S. corporation that is eligible for benefits under a comprehensive income tax treaty with the United States, which includes an exchange of information program or if the stock with respect to which the dividend was paid is readily tradable on an established United States securities market. The term excludes a corporation that is a passive foreign investment company.

Dividends received by the Fund from a real estate investment trust (“REIT”) or another RIC generally are qualified dividend income only to the extent the dividend

distributions are made out of qualified dividend income received by such REIT or RIC. It is expected that dividends received by the Fund from a REIT and distributed to a shareholder generally will be taxable to the shareholder as ordinary income.

For a dividend to be treated as qualified dividend income, the dividend must be received with respect to a share of stock held without being hedged by the Fund, and with respect to a share of the Fund held without being hedged by you, for 61 days during the 121-day period beginning at the date which is 60 days before the date on which such share becomes ex-dividend with respect to such dividend or, in the case of certain preferred stock, 91 days during the 181-day period beginning 90 days before such date.

If your Fund shares are loaned out pursuant to a securities lending arrangement, you may lose the ability to use foreign tax credits passed through by the Fund or to treat Fund dividends paid while the shares are held by the borrower as qualified dividend income.

In general, your distributions are subject to U.S. federal income tax for the year when they are paid. Certain distributions paid in January, however, may be treated as paid on December 31 of the prior year.

If the Fund’s distributions exceed current and accumulated earnings and profits, all or a portion of the distributions made in the taxable year may be recharacterized as a return of capital to shareholders. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and result in a higher capital gain or lower capital loss when those shares on which the distribution was received are sold. Once a shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain, if the shareholder holds shares of the Fund as capital assets.

If you are neither a resident nor a citizen of the United States or if you are a non-U.S. entity, the Fund’s ordinary income dividends (which include distributions of net short-term capital gains) will generally be subject to a 30% U.S. withholding tax, unless a lower treaty rate applies, provided that withholding tax will generally not apply to any gain or income realized by a non-U.S. shareholder in respect of any distributions of long-term capital gains or upon the sale or other disposition of shares of the Fund.

A 30% withholding tax will be imposed on dividends paid after December 31, 2013, and redemption proceeds paid after December 31, 2014, to (i) foreign financial institutions including non-U.S. investment funds unless they agree to collect and disclose to the Internal Revenue Service (“IRS”) information regarding their direct and indirect U.S. account holders and (ii) certain other foreign entities, unless they certify certain information regarding their direct and indirect U.S. owners. To avoid withholding, foreign financial institutions will need to enter into agreements with the IRS that state that they will provide the IRS information, including the name, address and taxpayer identification number of direct and indirect U.S. account holders, comply with due diligence procedures with respect to the identification of U.S. accounts, report to the IRS certain information with respect to U.S. accounts maintained, agree to withhold tax on certain payments made to non-compliant foreign financial institutions or to account holders who fail to provide the required information, and determine certain other information as to their account holders. Other foreign entities will need to

provide the name, address, and taxpayer identification number of each substantial U.S. owner or certifications of no substantial U.S. ownership unless certain exceptions apply.

Dividends, interest and capital gains earned by the Fund with respect to non-U.S. securities may give rise to withholding and other taxes imposed by non-U.S. countries. Tax conventions between certain countries and the United States may reduce or eliminate such taxes. If more than 50% of the total assets of the Fund at the close of a year consists of non-U.S. stocks or securities, the Fund may “pass through” to you certain non-U.S. income taxes (including withholding taxes) paid by the Fund. This means that you would be considered to have received as an additional dividend your share of such non-U.S. taxes, but you may be entitled to either a corresponding tax deduction in calculating your taxable income, or, subject to certain limitations, a credit in calculating your U.S. federal income tax.

For purposes of foreign tax credits for U.S. shareholders of the Fund, foreign capital gains taxes may not produce associated foreign source income, thereby limiting a U.S. person’s ability to use such credits.

If you are a resident or a citizen of the United States, by law, back-up withholding will apply to your distributions and proceeds if you have not provided a taxpayer identification number or social security number and made other required certifications.

Taxes When Shares are Sold. Currently, any capital gain or loss realized upon a sale of Fund shares is generally treated as a long-term gain or loss if the shares have been held for more than one year. Any capital gain or loss realized upon a sale of Fund shares held for one year or less is generally treated as short-term gain or loss, except that any capital loss on the sale of shares held for six months or less is treated as long-term capital loss to the extent that capital gain dividends were paid with respect to such shares. Beginning in 2013, any such capital gains, including from sales of Fund shares or from capital gain dividends, will be included in “net investment income” for purposes of the 3.8% U.S. federal Medicare contribution tax mentioned above.

The foregoing discussion summarizes some of the consequences under current U.S. federal tax law of an investment in the Fund. It is not a substitute for personal tax advice. You may also be subject to state and local taxation on Fund distributions and sales of shares. Consult your personal tax adviser about the potential tax consequences of an investment in shares of the Fund under all applicable tax laws.

Creations and Redemptions. Prior to trading in the secondary market, shares of the Fund are “created” at NAV by market makers, large investors and institutions only in block-size Creation Units of 50,000 shares or multiples thereof. Each “creator” or “Authorized Participant” enters into an authorized participant agreement with the Fund’s distributor, SEI Investments Distribution Co. (the “Distributor”). Only an Authorized Participant may create or redeem Creation Units directly with the Fund. A creation transaction, which is subject to acceptance by the transfer agent, generally takes place when an Authorized Participant deposits into the Fund a designated portfolio of securities and a specified amount of cash approximating the holdings of the Fund in exchange for a specified number of Creation Units. To the extent

practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund.

Similarly, shares can be redeemed only in Creation Units, generally for a designated portfolio of securities and a specified amount of cash held by the Fund (“Fund Securities”). Except when aggregated in Creation Units, shares are not redeemable by the Fund. The prices at which creations and redemptions occur are based on the next calculation of NAV after an order is received in a form described in the authorized participant agreement.

The Fund intends to comply with the U.S. federal securities laws in accepting securities for deposit and satisfying redemptions with redemption securities by, among other means, assuring that any securities accepted for deposit and any securities used to satisfy redemption requests will be sold in transactions that would be exempt from registration under the Securities Act of 1933, as amended (the “1933 Act”). Further, an Authorized Participant that is not a “qualified institutional buyer,” as such term is defined under Rule 144A of the 1933 Act, will not be able to receive Fund Securities that are restricted securities eligible for resale under Rule 144A.

Creations and redemptions must be made through a firm that is either a member of the Continuous Net Settlement System of the National Securities Clearing Corporation or a DTC participant and has executed an agreement with the Distributor with respect to creations and redemptions of Creation Unit aggregations. Information about the procedures regarding creation and redemption of Creation Units (including the cut-off times for receipt of creation and redemption orders) is included in the Fund’s SAI.

Because new shares may be created and issued on an ongoing basis, at any point during the life of the Fund a “distribution,” as such term is used in the 1933 Act, may be occurring. Broker-dealers and other persons are cautioned that some activities on their part may, depending on the circumstances, result in their being deemed participants in a distribution in a manner that could render them statutory underwriters and subject to the prospectus delivery and liability provisions of the 1933 Act. Any determination of whether one is an underwriter must take into account all the relevant facts and circumstances of each particular case.

Broker-dealers should also note that dealers who are not “underwriters” but are participating in a distribution (as contrasted to ordinary secondary transactions), and thus dealing with shares that are part of an “unsold allotment” within the meaning of Section 4(3)(C) of the 1933 Act, would be unable to take advantage of the prospectus delivery exemption provided by Section 4(3) of the 1933 Act. For delivery of prospectuses to exchange members, the prospectus delivery mechanism of Rule 153 under the 1933 Act is available only with respect to transactions on a national securities exchange.

Costs Associated with Creations and Redemptions. Authorized Participants are charged standard creation and redemption transaction fees to offset transfer and other transaction costs associated with the issuance and redemption of Creation Units. The standard creation and redemption transaction fees are set forth in the table below. The standard creation transaction fee is charged to the Authorized Participant on the day such Authorized Participant creates a Creation Unit, and is the same

regardless of the number of Creation Units purchased by the Authorized Participant on the applicable business day. Similarly, the standard redemption transaction fee is charged to the Authorized Participant on the day such Authorized Participant redeems a Creation Unit, and is the same regardless of the number of Creation Units redeemed by the Authorized Participant on the applicable business day. Creations and redemptions for cash (when cash creations and redemptions (in whole or in part) are available or specified) are also subject to an additional charge (up to the maximum amounts shown in the table below). This charge is intended to compensate for brokerage, tax, foreign exchange, execution, market impact and other costs and expenses related to cash transactions. Investors who use the services of a broker or other financial intermediary may pay fees for such services.

The following table shows, as of September 30, 2011, the approximate value of one Creation Unit, standard fees and maximum additional charges for creations and redemptions (as described above):

Householding. Householding is an option available to certain Fund investors. Householding is a method of delivery, based on the preference of the individual investor, in which a single copy of certain shareholder documents can be delivered to investors who share the same address, even if their accounts are registered under different names. Please contact your broker-dealer if you are interested in enrolling in householding and receiving a single copy of prospectuses and other shareholder documents, or if you are currently enrolled in householding and wish to change your householding status.

Distribution

The Distributor distributes Creation Units for the Fund on an agency basis. The Distributor does not maintain a secondary market in shares of the Fund. The Distributor has no role in determining the policies of the Fund or the securities that are purchased or sold by the Fund. The Distributor’s principal address is One Freedom Valley Drive, Oaks, PA 19456.

In addition, BFA or its Affiliates make payments to broker-dealers, banks or other financial intermediaries (together, “intermediaries”) related to marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems, or their making shares of the Fund and certain other iShares funds available to their customers. Such payments, which may be significant to the intermediary, are not made by the Fund. Rather, such payments are made by BFA or its Affiliates from their own resources, which come directly or

indirectly in part from fees paid by the iShares funds complex. Payments of this type are sometimes referred to as revenue-sharing payments. A financial intermediary may make decisions about which investment options it recommends or makes available, or the level of services provided, to its customers based on the revenue-sharing payments it is eligible to receive. Therefore, such payments to an intermediary create conflicts of interest between the intermediary and its customers and may cause the intermediary to recommend the Fund or other iShares funds over another investment. More information regarding these payments is contained in the Fund’s SAI. Please contact your salesperson or other investment professional for more information regarding any such payments his or her firm may receive from BFA or its Affiliates.

Financial Highlights

The financial highlights table is intended to help investors understand the Fund’s financial performance since inception. Certain information reflects financial results for a single share of the Fund. The total returns in the table represent the rate that an investor would have earned (or lost) on an investment in the Fund, assuming reinvestment of all dividends and distributions. This information has been audited by PricewaterhouseCoopers LLP, whose report is included, along with the Fund’s financial statements, in the Fund’s Annual Report (available upon request).

Supplemental Information

I. Premium/Discount Information

The table that follows presents information about the differences between the daily market price on secondary markets for shares of the Fund and the Fund’s NAV. NAV is the price at which the Fund issues and redeems shares. It is calculated in accordance with the standard formula for valuing mutual fund shares. The price used to calculate market returns (“Market Price”) of the Fund generally is determined using the midpoint between the highest bid and the lowest offer on the primary securities exchange on which shares of the Fund are listed for trading, as of the time that the Fund’s NAV is calculated. The Fund’s Market Price may be at, above or below its NAV. The NAV of the Fund will fluctuate with changes in the value of its portfolio holdings. The Market Price of the Fund will fluctuate in accordance with changes in its NAV, as well as market supply and demand.

Premiums or discounts are the differences (expressed as a percentage) between the NAV and Market Price of the Fund on a given day, generally at the time the NAV is calculated. A premium is the amount that the Fund is trading above the reported NAV, expressed as a percentage of the NAV. A discount is the amount that the Fund is trading below the reported NAV, expressed as a percentage of the NAV.

The following information shows the frequency of distributions of premiums and discounts for the Fund from October 1, 2010 through September 30, 2011.

Each line in the table shows the number of trading days in which the Fund traded within the premium/discount range indicated. The number of trading days in each premium/discount range is also shown as a percentage of the total number of trading days in the period covered by the table. All data presented here represents past performance, which cannot be used to predict future results.

Premium/Discount Range

Greater than 1.5% and Less than 2.0% 1 0.40%
Greater than 1.0% and Less than 1.5% 1 0.40

Less than -1.5% and Greater than -2.0% 7 2.77
Less than -2.0% and Greater than -2.5% 10 3.95
Less than -2.5% and Greater than -3.0% 3 1.19
   253 100.00%

II. Total Return Information

The table that follows presents information about the total returns of the Fund and the Underlying Index as of the fiscal year ended July 31, 2011.

“Average Annual Total Returns” represent the average annual change in value of an investment over the periods indicated. “Cumulative Total Returns” represent the total change in value of an investment over the period indicated.

The Fund’s NAV is the value of one share of the Fund as calculated in accordance with the standard formula for valuing mutual fund shares. The NAV return is based on the NAV of the Fund and the market return is based on the Market Price of the Fund. Market Price is determined by using the midpoint between the highest bid and the lowest offer on the primary stock exchange on which shares of the Fund are listed for trading, as of the time that the Fund’s NAV is calculated. Since shares of the Fund did not trade in the secondary market until after the Fund’s inception, for the period from inception to the first day of secondary market trading in shares of the Fund, the NAV of the Fund is used as a proxy for the Market Price to calculate market returns. Market and NAV returns assume that dividends and capital gain distributions have been reinvested in the Fund at Market Price and NAV, respectively.

An index is a statistical composite that tracks a specified financial market or sector. Unlike the Fund, the Underlying Index does not actually hold a portfolio of securities and therefore does not incur the expenses incurred by the Fund. These expenses negatively impact the performance of the Fund. Also, market returns do not include brokerage commissions that may be payable on secondary market transactions. If brokerage commissions were included, market returns would be lower. The returns shown in the following table do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption or sale of Fund shares. The investment return and principal value of shares of the Fund will vary with changes in market conditions. Shares of the Fund may be worth more or less than their original cost when they are redeemed or sold in the market. The Fund’s past performance is no guarantee of future results.

Fund Overview

iSHARES® MSCI ACWI ex US MATERIALS SECTOR INDEX FUND

Ticker: AXMT Stock Exchange: NYSE Arca

Investment Objective

The iShares MSCI ACWI ex US Materials Sector Index Fund (the “Fund”) seeks investment results that correspond generally to the price and yield performance, before fees and expenses, of the MSCI All Country World ex USA Materials Index (the “Underlying Index”).

Fees and Expenses

The following table describes the fees and expenses that you will incur if you own shares of the Fund. The investment advisory agreement between iShares Trust (the “Trust”) and BlackRock Fund Advisors (“BFA”) (the “Investment Advisory Agreement”) provides that BFA will pay all operating expenses of the Fund, except interest expenses, taxes, brokerage expenses, future distribution fees or expenses, and extraordinary expenses.

You may also incur usual and customary brokerage commissions when buying or selling shares of the Fund, which are not reflected in the example that follows:

Annual Fund Operating Expenses

Example. This Example is intended to help you compare the cost of owning shares of the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

1 Year
3 Years
5 Years
10 Years
$49 $154 $269 $604

Portfolio Turnover. The Fund may pay transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 5% of the average value of its portfolio.

Principal Investment Strategies

The Underlying Index is a free float-adjusted market capitalization-weighted index designed to measure the combined equity market performance of the materials sector of developed and emerging markets countries, excluding the United States. Component securities include those of chemical, construction materials, container and packing manufacturing, metals and mining, and paper and forest products companies. As of September 30, 2011, the Underlying Index consisted of companies in the following countries and regions: Australia, Austria, Belgium, Brazil, Canada, Chile, China, Colombia, the Czech Republic, Denmark, Egypt, Finland, France, Germany, Greece, Hong Kong, Hungary, India, Indonesia, Ireland, Israel, Italy, Japan, Malaysia, Mexico, Morocco, the Netherlands, New Zealand, Norway, Peru, the Philippines, Poland, Portugal, Russia, Singapore, South Africa, South Korea, Spain, Sweden, Switzerland, Taiwan, Thailand, Turkey and the United Kingdom (together, the “ACWI ex US materials sector countries”). As of September 30, 2011, the Underlying Index was comprised of 250 securities.

BFA uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to “beat” the index it tracks and does not seek temporary defensive positions when markets decline or appear overvalued.

Indexing may eliminate the chance that the Fund will substantially outperform the Underlying Index but also may reduce some of the risks of active management, such as poor security selection. Indexing seeks to achieve lower costs and better after-tax performance by keeping portfolio turnover low in comparison to actively managed investment companies.

BFA uses a representative sampling indexing strategy to manage the Fund. “Representative sampling” is an indexing strategy that involves investing in a representative sample of securities that collectively has an investment profile similar to the Underlying Index. The securities selected are expected to have, in the aggregate, investment characteristics (based on factors such as market capitalization and industry weightings), fundamental characteristics (such as return variability and yield) and liquidity measures similar to those of the Underlying Index. The Fund may or may not hold all of the securities in the Underlying Index.

The Fund generally invests at least 80% of its assets in securities of the Underlying Index or in depositary receipts representing securities of the Underlying Index. The Fund may invest the remainder of its assets in securities not included in the Underlying Index,

S-2   


Table Of Contents



but which BFA believes will help the Fund track the Underlying Index and in other investments including futures contracts, options on futures contracts, options and swaps related to the Underlying Index, as well as cash and cash equivalents, including shares of money market funds advised by BFA or its affiliates.

The Fund may lend securities representing up to one-third of the value of the Fund’s total assets (including the value of the collateral received).

The Underlying Index is sponsored by an organization (the “Index Provider”) that is independent of the Fund and BFA. The Index Provider determines the composition and relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index. The Fund’s Index Provider is MSCI Inc. (“MSCI”).

Industry Concentration Policy. The Fund will concentrate its investments (i.e., hold 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. For purposes of this limitation, securities of the U.S. government (including its agencies and instrumentalities) and repurchase agreements collateralized by U.S. government securities are not considered to be issued by members of any industry.

Summary of Principal Risks

As with any investment, you could lose all or part of your investment in the Fund, and the Fund’s performance could trail that of other investments. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund’s net asset value per share (“NAV”), trading price, yield, total return and ability to meet its investment objective.

Asset Class Risk. Securities in the Underlying Index or in the Fund’s portfolio may underperform in comparison to the general securities markets or other asset classes.

Commodity Risk. The Fund invests in economies that are susceptible to fluctuations in certain commodity markets. Any negative changes in commodity markets could have an adverse impact on those economies.

Concentration Risk. To the extent that the Fund’s investments are concentrated in a particular issuer, region, country, market, industry or asset class, the Fund may be susceptible to loss due to adverse occurrences affecting that issuer, region, country, market, industry or asset class.

Currency Risk. Because the Fund’s NAV is determined in U.S. dollars, the Fund’s NAV could decline if the currency of a non-U.S. market in which the Fund invests depreciates against the U.S. dollar.

Custody Risk. Less developed markets are more likely to experience problems with the clearing and settling of trades and the holding of securities by local banks, agents and depositories.

Emerging Markets Risk. The Fund’s investments in emerging markets may be subject to a greater risk of loss than investments in more developed markets. Emerging markets may be more likely to experience inflation risk, political turmoil and rapid changes in economic conditions than more

S-3   


Table Of Contents



developed markets. Emerging markets often have less uniformity in accounting and reporting requirements, unreliable securities valuation and greater risk associated with custody of securities.

Equity Securities Risk. Equity securities are subject to changes in value and their values may be more volatile than other asset classes.

Geographic Risk. A natural or other disaster could occur in a geographic region in which the Fund invests, which could affect the economy or particular business operations of companies in the specific geographic region, causing an adverse impact on the Fund’s investments in the affected region.

Issuer Risk. Fund performance depends on the performance of individual securities to which the Fund has exposure. Changes to the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA’s investment management strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares, losses from trading in secondary markets, periods of high volatility and disruption in the creation/redemption process of the Fund. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV.

Materials Sector Risk. Companies in the materials sector may be adversely impacted by the volatility of commodity prices, exchange rates, depletion of resources, over-production, litigation and government regulations, among other factors.

Metals and Mining Sector Risk. Companies in the metals and mining sector are susceptible to fluctuations in worldwide metal prices, and exploration and production costs. In addition, metals and mining companies may have significant operations in areas at risk for social and political unrest, security concerns and environmental damage. These companies may also be at risk for increased government regulation and intervention. As a result, such risks may adversely affect the issuers to which the Fund has exposure.

Non-Diversification Risk. The Fund may invest a large percentage of its assets in securities issued by or representing a small number of issuers. As a result, the Fund’s performance may depend on the performance of a small number of issuers.

Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers are subject to the risks associated with investing in those non-U.S. markets, such as heightened risks of inflation or nationalization. The Fund may lose money due to political, economic and geographic events affecting a non-U.S. issuer or market. The Fund is specifically exposed to European Economic Risk.

Passive Investment Risk. The Fund is not actively managed and BFA does not attempt to take defensive positions

S-4   


Table Of Contents



under any market conditions, including declining markets.

Privatization Risk. Some countries in which the Fund invests have begun a process of privatizing certain entities and industries. Privatized entities may lose money or be re-nationalized.

Reliance on Trading Partners Risk. The Fund invests in countries whose economies are heavily dependent upon trading with key partners. Any reduction in this trading may have an adverse impact on the Fund’s investments. Through its trading partners, the Fund is particularly exposed to U.S. Trading Partner Risk.

Securities Lending Risk. The Fund may engage in securities lending. Securities lending involves the risk that the Fund may lose money because the borrower of the Fund’s loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Security Risk. Some countries and regions in which the Fund invests have experienced security concerns. Incidents involving a country’s or region’s security may cause uncertainty in these markets and may adversely affect their economies and the Fund’s investments.

Structural Risk. The countries in which the Fund invests may be subject to considerable degrees of economic, political and social instability.

Tracking Error Risk. The performance of the Fund may diverge from that of the Underlying Index. Because the Fund employs a representative sampling strategy, the Fund may experience tracking error to a greater extent than a fund that seeks to replicate an index. BFA EXPECTS THAT THE FUND MAY EXPERIENCE HIGHER TRACKING ERROR THAN IS TYPICAL FOR SIMILAR INDEX EXCHANGE-TRADED FUNDS.

Valuation Risk. The value of the securities in the Fund’s portfolio may change on days when shareholders will not be able to purchase or sell the Fund’s shares.

Performance Information

As of the date of the Fund’s prospectus (the “Prospectus”), the Fund has been in operation for less than one full calendar year and therefore does not report its performance information.

Management

Investment Adviser. BlackRock Fund Advisors.

Portfolio Managers. Rene Casis, Diane Hsiung and Greg Savage (the “Portfolio Managers”) are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager supervises a portfolio management team. Mr. Casis has been a Portfolio Manager of the Fund since 2010. Ms. Hsiung and Mr. Savage have been Portfolio Managers of the Fund since inception.

Purchase and Sale of Fund Shares

The Fund is an exchange-traded fund (commonly referred to as an “ETF”). Individual Fund shares may only be purchased and sold on a national securities exchange through a broker-dealer. The price of Fund shares is based on market price, and because ETF shares trade at market prices rather than NAV, shares may trade at a price greater than NAV (a premium) or less than NAV (a discount). The Fund will only issue or redeem shares that have been aggregated into blocks of 50,000 shares or multiples thereof (“Creation Units”) to authorized participants who have entered into agreements with the Fund’s distributor. The Fund generally will issue or redeem Creation Units in return for a designated portfolio of securities (and an amount of cash) that the Fund specifies each day.

Tax Information

The Fund intends to make distributions that may be taxable to you as ordinary income or capital gains, unless you are investing through a tax-deferred arrangement such as a 401(k) plan or an individual retirement account (“IRA”).

Payments to Broker-Dealers and other Financial Intermediaries

If you purchase shares of the Fund through a broker-dealer or other financial intermediary (such as a bank), BFA or other related companies may pay the intermediary for marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems or other services related to the sale or promotion of the Fund. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.

More Information About the Fund

This Prospectus contains important information about investing in the Fund. Please read this Prospectus carefully before you make any investment decisions. Additional information regarding the Fund is available at www.iShares.com.

BFA is the investment adviser to the Fund. Shares of the Fund are listed for trading on NYSE Arca, Inc. (“NYSE Arca”). The market price for a share of the Fund may be different from the Fund’s most recent NAV.

ETFs are funds that trade like other publicly-traded securities. The Fund is designed to track an index. Similar to shares of an index mutual fund, each share of the Fund represents a partial ownership in an underlying portfolio of securities intended to track a market index. Unlike shares of a mutual fund, which can be bought and redeemed from the issuing fund by all shareholders at a price based on NAV, shares of the Fund may be purchased or redeemed directly from the Fund at NAV solely by authorized participants. Also unlike shares of a mutual fund, shares of the Fund are listed on a national securities exchange and trade in the secondary market at market prices that change throughout the day.

The Fund invests in a particular segment of the securities markets and seeks to track the performance of a securities index that generally is not representative of the market as a whole. The Fund is designed to be used as part of broader asset allocation strategies. Accordingly, an investment in the Fund should not constitute a complete investment program.

An index is a theoretical financial calculation while the Fund is an actual investment portfolio. The performance of the Fund and the Underlying Index may vary due to transaction costs, non-U.S. currency valuations, asset valuations, corporate actions (such as mergers and spin-offs), timing variances and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions (such as diversification requirements) that apply to the Fund but not to the Underlying Index or to the use of representative sampling. “Tracking error” is the difference between the performance (return) of the Fund’s portfolio and that of the Underlying Index. BFA expects that, over time, the Fund’s tracking error will not exceed 5%. Because the Fund uses a representative sampling indexing strategy, it can be expected to have a larger tracking error than if it used a replication indexing strategy. “Replication” is an indexing strategy in which a fund invests in substantially all of the securities in its underlying index in approximately the same proportions as in the underlying index.

An investment in the Fund is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, BFA or any of its affiliates.

The Fund’s investment objective and the Underlying Index may be changed without shareholder approval.

A Further Discussion of Principal Risks

The Fund is subject to various risks, including the principal risks noted below, any of which may adversely affect the Fund’s NAV, trading price, yield, total return and ability to meet its investment objective. You could lose all or part of your investment in the Fund, and the Fund could underperform other investments.

Asset Class Risk. The securities in the Underlying Index or in the Fund’s portfolio may underperform the returns of other securities or indexes that track other countries, groups of countries, regions, industries, groups of industries, markets, asset classes or sectors. Various types of securities or indexes tend to experience cycles of outperformance and underperformance in comparison to the general securities markets.

Commodity Risk. Economies and companies whose performance is reflected in the Fund’s portfolio or Underlying Index may be adversely affected by changes or trends in commodity prices. Commodity prices may be influenced or characterized by unpredictable factors, including, where applicable, high volatility, changes in supply and demand relationships, weather, agriculture, trade, pestilence, political instability, changes in interest rates and monetary and other governmental policies, action and inaction. Securities of companies held by the Fund that are dependent on a single commodity, or are concentrated in a single commodity sector, may typically exhibit even higher volatility attributable to commodity prices.

Concentration Risk. To the extent that the Fund’s portfolio reflects the Underlying Index’s concentration in the securities of a particular issuer or issuers in a particular country, group of countries, region, market, industry, group of industries, sector or asset class, the Fund may be adversely affected by the performance of those securities, may be subject to increased price volatility and may be more susceptible to adverse economic, market, political or regulatory occurrences affecting that issuer, country, group of countries, region, market, industry, group of industries, sector or asset class.

Currency Risk. Because the Fund’s NAV is determined on the basis of the U.S. dollar, investors may lose money if the currency of a non-U.S. market in which the Fund invests depreciates against the U.S. dollar, even if the local currency value of the Fund’s holdings in that market increases.



Custody Risk. Custody risk refers to the risks inherent in the process of clearing and settling trades and the holding of securities by local banks, agents and depositories. Low trading volumes and volatile prices in less developed markets may make trades harder to complete and settle, and governments or trade groups may compel local agents to hold securities in designated depositories that are not subject to independent evaluation. Local agents are held only to the standards of care of their local markets. In general, the less developed a country’s securities market is, the greater the likelihood of custody problems.

Emerging Markets Risk. Investments in emerging markets are subject to a greater risk of loss than investments in more developed markets. This is due to, among other things, the potential for greater market volatility, lower trading volume, inflation, political and economic instability, greater risk of a market shutdown and more

governmental limitations on foreign investments than typically found in more developed markets. In addition, emerging markets often have less uniformity in accounting and reporting requirements, unreliable securities valuation and greater risks associated with custody of securities.

Equity Securities Risk. The Fund invests in equity securities, which are subject to changes in value that may be attributable to market perception of a particular issuer or to general stock market fluctuations that affect all issuers. Investments in equity securities may be more volatile than investments in other asset classes.

European Economic Risk. The Economic and Monetary Union of the European Union (the “EU”) requires member countries to comply with restrictions on inflation rates, deficits, interest rates, debt levels and fiscal and monetary controls, each of which may significantly affect every country in Europe. Decreasing imports or exports, changes in governmental or EU regulations on trade, changes in the exchange rate of the euro, the default or threat of default by an EU member country on its sovereign debt, and/or an economic recession in an EU member country may have a significant adverse effect on the economies of EU member countries and their trading partners, including some or all of the ACWI ex US materials sector countries. The European financial markets have recently experienced volatility and have been adversely affected by concerns about economic downturns, credit rating downgrades, rising government debt levels and possible default on or restructuring of government debt in several European countries, including Greece, Ireland, Italy, Portugal and Spain. A default or debt restructuring by any European country would adversely impact holders of that country’s debt, and sellers of credit default swaps linked to that country’s creditworthiness, which may be located in countries other than those listed in the previous sentence. These events have adversely affected the value and exchange rate of the euro and may continue to significantly affect the economies of every country in Europe, including EU member countries that do not use the euro and non-EU member countries.

Geographic Risk. Some markets in which the Fund invests are located in parts of the world that have historically been prone to natural disasters, such as earthquakes, volcanoes, droughts, floods, hurricanes and tsunamis, and are economically sensitive to environmental events. Any natural or other disaster could have a significant adverse impact on the economies of these geographic areas, causing an adverse impact on the Fund’s investments in the affected region.

Issuer Risk. The performance of the Fund depends on the performance of individual securities to which the Fund has exposure. Any issuer of these securities may perform poorly, causing the value of its securities to decline. Poor performance may be caused by poor management decisions, competitive pressures, changes in technology, expiration of patent protection, disruptions in supply, labor problems or shortages, corporate restructurings, fraudulent disclosures or other factors. Issuers may, in times of distress or at their own discretion, decide to reduce or eliminate dividends, which may also cause their stock prices to decline.

Management Risk. The Fund may not fully replicate the Underlying Index and may hold securities not included in the Underlying Index. As a result, the Fund is subject to the risk that BFA’s investment management strategy, the implementation of which is subject to a number of constraints, may not produce the intended results.

Market Risk. The Fund could lose money due to short-term market movements and over longer periods during market downturns. Securities may decline in value due to factors affecting securities markets generally or particular industries represented in the markets. The value of a security may decline due to general market conditions, economic trends or events that are not specifically related to the issuer of the security or to factors that affect a particular industry or industries. During a general downturn in the securities markets, multiple asset classes may be negatively affected.

Market Trading Risk

Absence of Active Market. Although shares of the Fund are listed for trading on one or more stock exchanges, there can be no assurance that an active trading market for such shares will develop or be maintained.

Risk of Secondary Listings. The Fund’s shares may be listed or traded on U.S. and non-U.S. stock exchanges other than the U.S. stock exchange where the Fund’s primary listing is maintained. There can be no assurance that the Fund’s shares will continue to trade on any such stock exchange or in any market or that the Fund’s shares will continue to meet the requirements for listing or trading on any exchange or in any market. The Fund’s shares may be less actively traded in certain markets than others, and investors are subject to the execution and settlement risks and market standards of the market where they or their broker direct their trades for execution. Certain information available to investors who trade Fund shares on a U.S. stock exchange during regular U.S. market hours may not be available to investors who trade in other markets, which may result in secondary market prices in such markets being less efficient.

Secondary Market Trading Risk. Shares of the Fund may trade in the secondary market at times when the Fund does not accept orders to purchase or redeem shares. At such times, shares may trade in the secondary market with more significant premiums or discounts than might be experienced at times when the Fund accepts purchase and redemption orders.

Secondary market trading in Fund shares may be halted by a stock exchange because of market conditions or other reasons. In addition, trading in Fund shares on a stock exchange or in any market may be subject to trading halts caused by extraordinary market volatility pursuant to “circuit breaker” rules on the stock exchange or market. There can be no assurance that the requirements necessary to maintain the listing or trading of Fund shares will continue to be met or will remain unchanged.

Shares of the Fund May Trade at Prices Other Than NAV. Shares of the Fund trade on stock exchanges at prices at, above or below their most recent NAV. The NAV of the Fund is calculated at the end of each business day and fluctuates with changes in the market value of the Fund’s holdings since the most recent calculation. The trading prices of the Fund’s shares fluctuate continuously throughout trading hours based on market supply and demand rather than NAV. The trading prices of the Fund’s shares may deviate significantly from NAV during periods of market volatility. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV. However, because shares can be created and redeemed in Creation Units at NAV (unlike shares of many closed-end funds, which

frequently trade at appreciable discounts from, and sometimes at premiums to, their NAVs), BFA believes that large discounts or premiums to the NAV of the Fund are not likely to be sustained over the long-term. While the creation/redemption feature is designed to make it likely that the Fund’s shares normally will trade on stock exchanges at prices close to the Fund’s next calculated NAV, exchange prices are not expected to correlate exactly with the Fund’s NAV due to timing reasons as well as market supply and demand factors. In addition, disruptions to creations and redemptions or extreme market volatility may result in trading prices for shares of the Fund that differ significantly from its NAV.

Costs of Buying or Selling Fund Shares. Buying or selling Fund shares on an exchange involves two types of costs that apply to all securities transactions. When buying or selling shares of the Fund through a broker, you will likely incur a brokerage commission or other charges imposed by brokers as determined by that broker. In addition, you may incur the cost of the “spread” – that is, the difference between what investors are willing to pay for Fund shares (the “bid” price) and the price at which they are willing to sell Fund shares (the “ask” price). Because of the costs inherent in buying or selling Fund shares, frequent trading may detract significantly from investment results and an investment in Fund shares may not be advisable for investors who anticipate regularly making small investments.

Materials Sector Risk. Companies in the materials sector could be adversely affected by commodity price volatility, exchange rates, import controls, increased competition, depletion of resources, technical progress, labor relations, exchange rates and government regulations, among other factors. Also, companies in the materials sector are at risk of liability for environmental damage and product liability claims. Production of materials may exceed demand as a result of market imbalances or economic downturns, leading to poor investment returns.

Metals and Mining Sector Risk. The Fund will invest in securities that are issued by and/or have exposure to, companies primarily involved in the metals and mining sector. Investments in metals and mining sector companies may be speculative and subject to greater price volatility than investments in other types of companies. The profitability of companies in the metals and mining sector is related to, among other things, worldwide metal prices, and exploration and production costs. Worldwide metal prices may fluctuate substantially over short periods of time, so the Fund’s share price may be more volatile than other types of investments. In addition, metals and mining companies may be significantly affected by changes in global demand for certain metals, economic developments, energy conservation, exchange rates, the success of exploration projects, interest rates, economic conditions, tax treatment, government regulation and intervention, and world events in the regions that the companies to which the Fund has exposure operate (e.g., expropriation, nationalization, confiscation of assets and property or the imposition of restrictions on foreign investments and repatriation of capital, military coups, social unrest, violence and labor unrest). Metals and mining companies may also be subject to the effects of competitive pressures in the metals and mining sector.

Non-Diversification Risk. The Fund is classified as “non-diversified.” This means that the Fund may invest a large percentage of its assets in securities issued by or

representing a small number of issuers. As a result, the Fund may be more susceptible to the risks associated with these particular issuers, or to a single economic, political or regulatory occurrence affecting these issuers.

Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers are subject to all of the risks of investing in the markets where such issuers are located, including heightened risks of inflation or nationalization and market fluctuations caused by economic and political developments. As a result of investing in non-U.S. securities, the Fund may be subject to increased risk of loss caused by any of the factors listed below:

  • Lower levels of liquidity and market efficiency;
  • Greater securities price volatility;
  • Exchange rate fluctuations and exchange controls;
  • Less availability of public information about issuers;
  • Limitations on foreign ownership of securities;
  • Imposition of withholding or other taxes;
  • Imposition of restrictions on the expatriation of the funds or other assets of the Fund;
  • Higher transaction and custody costs and delays in settlement procedures;
  • Difficulties in enforcing contractual obligations;
  • Lower levels of regulation of the securities market;
  • Weaker accounting, disclosure and reporting requirements; and
  • Legal principles related to corporate governance, directors’ fiduciary duties and liabilities and stockholders’ rights in markets in which the Fund invests may differ and/or may not be as extensive or protective as those that apply in the United States.

Passive Investment Risk. The Fund is not actively managed and may be affected by a general decline in market segments related to the Underlying Index. The Fund invests in securities included in, or representative of, the Underlying Index regardless of their investment merits. BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

Privatization Risk. Some countries in which the Fund invests have begun a process of privatizing certain entities and industries. In some instances, investors in newly privatized entities have suffered losses due to the inability of the newly privatized entities to adjust quickly to a competitive environment or changing regulatory and legal standards or, in some cases, due to re-nationalization of such privatized entities. There is no assurance that such losses will not recur.

Reliance on Trading Partners Risk. The economies of the ACWI ex US materials sector countries are dependent on each other and on the United States as key trading partners. Reduction in spending on the products and services of the ACWI ex US materials sector countries by any of their key trading partners, institution of tariffs or other trade barriers or a slowdown in the economies of any of their key trading partners may cause an adverse impact on the economies of the ACWI ex US materials

sector countries.


U.S. Trading Partners Risk. The United States is a significant, and in some cases the most significant, trading partner of or foreign investor in certain ACWI ex US materials sector countries and the economies of these countries may be particularly affected by changes in the U.S. economy. Decreasing U.S. imports, new trade regulations, changes in the U.S. dollar exchange rate or a recession in the United States may have a material adverse effect on the economies of ACWI ex US materials sector countries.

Securities Lending Risk. The Fund may engage in securities lending. Securities lending involves the risk that the Fund may lose money because the borrower of the Fund’s loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for the loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Security Risk. Some geographic areas in which the Fund invests have experienced acts of terrorism or strained international relations due to territorial disputes, historical animosities or other defense concerns. These situations may cause uncertainty in the markets of these geographic areas and may adversely affect the performance of their economies.

Structural Risk. Certain political, economic, legal and currency risks have contributed to a high degree of price volatility in the equity markets of the ACWI ex US materials sector countries and could adversely affect investments in the Fund:

Political and Social Risk. Disparities of wealth, the pace and success of democratization and ethnic, religious and racial disaffection, among other factors, have led to social unrest, violence and labor unrest in some ACWI ex US materials sector countries. Unanticipated or sudden political or social developments may result in sudden and significant investment losses.

Economic Risk. Some ACWI ex US materials sector countries may experience economic instability, including instability resulting from substantial rates of inflation or significant devaluations of their currency, or economic recessions causing a negative effect on the economies and securities markets of their economies. Some of these countries may also impose restrictions on the exchange or export of currency or adverse currency exchange rates and may be characterized by a lack of available currency hedging instruments.

Expropriation and/or Nationalization Risk. Investments in certain ACWI ex US materials sector countries may be subject to loss due to expropriation or nationalization of assets and property or the imposition of restrictions on foreign investments and repatriation of capital.

Large Government Debt Risk. Chronic structural public sector deficits in some ACWI ex US materials sector countries may adversely impact investments in the Fund.

Tracking Error Risk. Imperfect correlation between the Fund’s portfolio securities and those in the Underlying Index, rounding of prices, changes to the Underlying Index and regulatory requirements may cause tracking error, which is the divergence of the

Fund’s performance from that of the Underlying Index. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Underlying Index does not. Because the Fund employs a representative sampling strategy, the Fund may experience tracking error to a greater extent than a fund that seeks to replicate an index. BFA EXPECTS THAT THE FUND MAY EXPERIENCE HIGHER TRACKING ERROR THAN IS TYPICAL FOR SIMILAR INDEX ETFS.

Valuation Risk. Because non-U.S. exchanges may be open on days when the Fund does not price its shares, the value of the securities in the Fund’s portfolio may change on days when shareholders will not be able to purchase or sell the Fund’s shares. In addition, for purposes of calculating the Fund’s NAV, the value of assets denominated in non-U.S. currencies is converted into U.S. dollars using exchange rates deemed appropriate by BFA. This conversion may result in a difference between the prices used to calculate the Fund’s NAV and the prices used by the Underlying Index, which, in turn, could result in a difference between the Fund’s performance and the performance of the Underlying Index.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

Asian Economic Risk. Certain Asian economies have experienced over-extension of credit, currency devaluations and restrictions, high unemployment, high inflation, decreased exports and economic recessions. Economic events in any one Asian country may have a significant economic effect on the entire Asian region, as well as on major trading partners outside Asia, and any adverse event in the Asian markets may have a significant adverse effect on some or all of the ACWI ex US materials sector countries.

Australasian Economic Risk. The economies of Australasia, which include Australia and New Zealand, are dependent on exports from the agricultural and mining sectors. This makes Australasian economies susceptible to fluctuations in the commodity markets. Australasian economies are also increasingly dependent on their growing service industries. Because the economies of Australasia are dependent on the economies of Asia, Europe and the United States as key trading partners and investors, reduction in spending by any of these trading partners on Australasian products and services, or negative changes in any of these economies, may cause an adverse impact on some or all of the Australasian economies.

Central and South American Economic Risk. The economies of certain ACWI ex US materials sector countries are affected by the economies of Central and South American countries, some of which have experienced high interest rates, economic volatility, inflation, currency devaluations, government defaults and high unemployment rates. In addition, commodities (such as oil, gas and minerals) represent a significant percentage of the region’s exports and many economies in this region are particularly sensitive to fluctuations in commodity prices. Adverse economic events in one country may have a significant adverse effect on other countries in this region and on some economies of the ACWI ex US materials sector countries.

Mid-Capitalization Companies Risk. Many of the companies in which the Fund invests are considered mid-capitalization companies. Stock prices of mid-capitalization companies may be more volatile than those of large-capitalization companies and, therefore, the Fund’s share price may be more volatile than those of funds that invest a larger percentage of their assets in stocks issued by large-capitalization companies. Stock prices of mid-capitalization companies are also more vulnerable than those of large-capitalization companies to adverse business or economic developments, and the stocks of mid-capitalization companies may be less liquid, making it difficult for the Fund to buy and sell them. In addition, mid-capitalization companies generally have less diverse product lines than large-capitalization companies and are more susceptible to adverse developments related to their products.

North American Economic Risk. The United States is Canada’s and Mexico’s largest trading and investment partner. The Canadian and Mexican economies are significantly affected by developments in the U.S. economy. Since the implementation of the North American Free Trade Agreement (“NAFTA”) in 1994 among Canada, the United States and Mexico, total merchandise trade between the three countries have increased. To further this relationship, the three NAFTA countries entered into the Security and Prosperity Partnership of North America in March 2005, which may further affect Canada’s and Mexico’s dependency on the U.S. economy. Economic events in any one North American country can have a significant economic effect on the entire North American region, and on some or all of the North American countries in which the Fund invests.

Small-Capitalization Companies Risk. Many of the companies in which the Fund invests are considered small-capitalization companies. Stock prices of small-capitalization companies may be more volatile than those of larger companies and, therefore, the Fund’s share price may be more volatile than those of funds that invest a larger percentage of their assets in stocks issued by mid- or large-capitalization companies. Stock prices of small-capitalization companies are generally more vulnerable than those of mid- or large-capitalization companies to adverse business and economic developments. Securities of small-capitalization companies may be thinly traded, making it difficult for the Fund to buy and sell them. In addition, small-capitalization companies are typically less financially stable than larger, more established companies and may depend on a small number of essential personnel, making them more vulnerable to loss of personnel. Small-capitalization companies also normally have less diverse product lines than mid- or large-capitalization companies and are more susceptible to adverse developments concerning their products.

Portfolio Holdings Information

A description of the Trust’s policies and procedures with respect to the disclosure of the Fund’s portfolio securities is available in the Fund’s Statement of Additional Information (“SAI”). The top holdings of the Fund can be found at www.iShares.com. Fund fact sheets provide information regarding the Fund’s top holdings and may be requested by calling 1-800-iShares (1-800-474-2737).

Management

Investment Adviser. As investment adviser, BFA has overall responsibility for the general management and administration of the Trust. BFA provides an investment program for the Fund and manages the investment of the Fund’s assets. In managing the Fund, BFA may draw upon the research and expertise of its asset management affiliates with respect to certain portfolio securities. In seeking to achieve the Fund’s investment objective, BFA uses teams of portfolio managers, investment strategists and other investment specialists. This team approach brings together many disciplines and leverages BFA’s extensive resources.

Pursuant to the Investment Advisory Agreement between BFA and the Trust (entered into on behalf of the Fund), BFA is responsible for substantially all expenses of the Fund, except interest expenses, taxes, brokerage expenses, future distribution fees or expenses and extraordinary expenses.

For its investment advisory services to the Fund, BFA is entitled to receive a management fee from the Fund based on a percentage of the Fund’s average daily net assets, at the annual rate of 0.48%.

BFA is located at 400 Howard Street, San Francisco, CA 94105. It is a wholly owned subsidiary of BTC, which in turn is indirectly wholly-owned by BlackRock, Inc. (“BlackRock”). As of September 30, 2011, BTC and its affiliates, including BFA and BlackRock, provided investment advisory services for assets in excess of $3.35 trillion. BFA, BTC, BlackRock Execution Services, BlackRock and their affiliates deal, trade and invest for their own accounts in the types of securities in which the Fund may also invest.

A discussion regarding the basis for the Trust’s Board of Trustees’ (the “Board”) approval of the Investment Advisory Agreement with BFA is available in the Fund’s annual report for the period ended July 31.

Portfolio Managers. Rene Casis, Diane Hsiung and Greg Savage are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager is responsible for various functions related to portfolio management, including, but not limited to, investing cash inflows, coordinating with members of his or her portfolio management team to focus on certain asset classes, implementing investment strategy, researching and reviewing investment strategy and overseeing members of his or her portfolio management team that have more limited responsibilities.

Rene Casis has been employed by BFA (formerly, Barclays Global Fund Advisors (“BGFA”)) and BTC (formerly, Barclays Global Investors, N.A. (“BGI”)) as a senior portfolio manager since 2009. From 2005 to 2009, Mr. Casis was a trader at Barclays Capital. Prior to that, Mr. Casis was a portfolio manager from 2000 to 2005 for BGFA and BGI. Mr. Casis has been a Portfolio Manager of the Fund since 2010.

Diane Hsiung has been employed by BFA and BTC as a senior portfolio manager since 2007. Prior to that, Ms. Hsiung was a portfolio manager from 2002 to 2006 for BGFA and BGI. Ms. Hsiung has been a Portfolio Manager of the Fund since inception.

Greg Savage has been employed by BFA and BTC as a senior portfolio manager since 2006. Prior to that, Mr. Savage was a portfolio manager from 2001 to 2006 for BGFA and BGI. Mr. Savage has been a Portfolio Manager of the Fund since inception.

The Fund’s SAI provides additional information about the Portfolio Managers’ compensation, other accounts managed by the Portfolio Managers and the Portfolio Managers’ ownership (if any) of shares in the Fund.

Administrator, Custodian and Transfer Agent. State Street Bank and Trust Company (“State Street”) is the administrator, custodian and transfer agent for the Fund.

Conflicts of Interest. BFA wants you to know that there are certain entities with which BFA has relationships that may give rise to conflicts of interest, or the appearance of conflicts of interest. These entities include the following: BFA’s affiliates (including BlackRock and The PNC Financial Services Group, Inc., and each of their affiliates, directors, partners, trustees, managing members, officers and employees (collectively, the “Affiliates”)) and BlackRock’s significant shareholder, Barclays Bank PLC and its affiliates, including Barclays PLC (each, an “Entity” and together, the “Entities”).

The activities of BFA, the Affiliates and the Entities in the management of, or their interest in, their own accounts and other accounts they manage, may present conflicts of interest that could disadvantage the Fund and the shareholders. BFA and its Affiliates or the Entities provide investment management services to other funds and discretionary managed accounts that may follow an investment program similar to that of the Fund. BFA, its Affiliates and the Entities are involved worldwide with a broad spectrum of financial services and asset management activities and may engage in the ordinary course of business in activities in which their interests or the interests of their clients may conflict with those of the Fund. BFA, one or more of the Affiliates or the Entities acts, or may act, as an investor, investment banker, research provider, investment manager, financier, underwriter, advisor, market maker, trader, prime broker, lender, agent or principal, and have other direct and indirect interests, in securities, currencies and other instruments in which the Fund may directly or indirectly invest. Thus, it is likely that the Fund will have multiple business relationships with and will invest in, engage in transactions with, make voting decisions with respect to, or obtain services from, entities for which BFA, an Affiliate or an Entity performs or seeks to perform investment banking or other services.

BFA or one or more Affiliates or Entities may engage in proprietary trading and advise accounts and funds that have investment objectives similar to those of the Fund and/or that engage in and compete for transactions in the same types of securities, currencies and other instruments as the Fund, including in securities issued by other open-end and closed-end investment management companies, including investment companies that are affiliated with the Fund and BFA, to the extent permitted under the Investment Company Act of 1940, as amended (the “1940 Act”). The trading activities of BFA, these Affiliates and Entities are carried out without reference to positions held directly or indirectly by the Fund and may result in BFA, an Affiliate or an Entity having positions that are adverse to those of the Fund.

No Affiliate or Entity is under any obligation to share any investment opportunity, idea or strategy with the Fund. As a result, an Affiliate or an Entity may compete with the Fund for appropriate investment opportunities. As a result of this and several other factors, the results of the Fund’s investment activities may differ from those of an Affiliate or an Entity and of other accounts managed by an Affiliate or an Entity, and it is possible that the Fund could sustain losses during periods in which one or more Affiliates or Entities and other accounts achieve profits on their trading for proprietary or other accounts. The opposite result is also possible.

The Fund may, from time to time, enter into transactions in which BFA or an Affiliate’s or an Entity’s clients have an interest adverse to the Fund. Furthermore, transactions undertaken by Affiliate-advised clients may adversely impact the Fund. Transactions by one or more Affiliate- or Entity-advised clients or BFA may have the effect of diluting or otherwise disadvantaging the values, prices or investment strategies of the Fund.

An Entity may maintain securities indices as part of the product offerings. Index-based funds seek to track the performance of securities indices and may use the name of the index in the fund name. Index providers, including the Entities, may be paid licensing fees for use of their indices or index names. Entities will not be obligated to license their indices to BFA and its Affiliates, and BFA and its Affiliates will not be assured that the terms of any index licensing agreement with the Entities will be as favorable as those terms offered to other index licensees.

The Fund’s activities may be limited because of regulatory restrictions applicable to one or more Affiliates or Entities, and/or their internal policies designed to comply with such restrictions. In addition, the Fund may invest in securities of companies with which an Affiliate or an Entity has or is trying to develop investment banking relationships or in which an Affiliate or an Entity has significant debt or equity investments. The Fund also may invest in securities of companies for which an Affiliate or an Entity provides or may some day provide research coverage. An Affiliate or an Entity may have business relationships with and purchase or distribute or sell services or products from or to distributors, consultants or others who recommend the Fund or who engage in transactions with or for the Fund, and may receive compensation for such services. The Fund may also make brokerage and other payments to Affiliates or Entities in connection with the Fund’s portfolio investment transactions.

Pursuant to a securities lending program approved by the Board, the Fund has retained an Affiliate of BFA to serve as the securities lending agent for the Fund to the extent that the Fund participates in the securities lending program. For these services, the lending agent may receive a fee from the Fund, including a fee based on the returns earned on the Fund’s investment of the cash received as collateral for any loaned securities. In addition, one or more Affiliates may be among the entities to which the Fund may lend its portfolio securities under the securities lending program.

The activities of BFA, the Affiliates or Entities may give rise to other conflicts of interest that could disadvantage the Fund and the shareholders. BFA has adopted policies and procedures designed to address these potential conflicts of interest. See the Fund’s SAI for further information.

Shareholder Information

Additional shareholder information, including how to buy and sell shares of the Fund, is available free of charge by calling toll-free: 1-800-iShares (1-800-474-2737) or visiting our website at www.iShares.com.

Buying and Selling Shares. Shares of the Fund may be acquired or redeemed directly from the Fund only in Creation Units or multiples thereof, as discussed in the Creations and Redemptions section of this Prospectus. Only an Authorized Participant (as defined in the Creations and Redemptions section) may engage in creation or redemption transactions directly with the Fund. Once created, shares of the Fund generally trade in the secondary market in amounts less than a Creation Unit.

Shares of the Fund are listed on a national securities exchange for trading during the trading day. Shares can be bought and sold throughout the trading day like shares of other publicly-traded companies. The Trust does not impose any minimum investment for shares of the Fund purchased on an exchange. The Fund’s shares trade under the trading symbol “AXMT.”

Buying or selling Fund shares on an exchange involves two types of costs that may apply to all securities transactions. When buying or selling shares of the Fund through a broker, you will likely incur a brokerage commission or other charges determined by your broker. The commission is frequently a fixed amount and may be a significant proportional cost for investors seeking to buy or sell small amounts of shares. In addition, you may incur the cost of the “spread” – that is, any difference between the bid price and the ask price. The spread varies over time for shares of the Fund based on the trading volume and market liquidity, and is generally lower if the Fund has a lot of trading volume and market liquidity, and higher if the Fund has little trading volume and market liquidity.

The Board has adopted a policy of not monitoring for frequent purchases and redemptions of Fund shares (“frequent trading”) that appear to attempt to take advantage of a potential arbitrage opportunity presented by a lag between a change in the value of the Fund’s portfolio securities after the close of the primary markets for the Fund’s portfolio securities and the reflection of that change in the Fund’s NAV (“market timing”), because the Fund generally sells and redeems its shares directly through transactions that are in-kind and/or for cash, subject to the conditions described below under Creations and Redemptions. The Board has not adopted a policy of monitoring for other frequent trading activity because shares of the Fund are listed for trading on a national securities exchange.

The national securities exchange on which the Fund’s shares are listed is open for trading Monday through Friday and is closed on weekends and the following holidays: New Year’s Day, Martin Luther King, Jr. Day, Presidents’ Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day. The Fund’s primary listing exchange is NYSE Arca.

Section 12(d)(1) of the 1940 Act restricts investments by investment companies in the securities of other investment companies. Registered investment companies are permitted to invest in the Fund beyond the limits set forth in Section 12(d)(1), subject to certain terms and conditions set forth in SEC rules or in an SEC exemptive order

issued to the Trust. In order for a registered investment company to invest in shares of the Fund beyond the limitations of Section 12(d)(1) pursuant to the exemptive relief obtained by the Trust, the registered investment company must enter into an agreement with the Trust.

Book Entry. Shares of the Fund are held in book-entry form, which means that no stock certificates are issued. The Depository Trust Company (“DTC”) or its nominee is the record owner of all outstanding shares of the Fund and is recognized as the owner of all shares for all purposes.

Investors owning shares of the Fund are beneficial owners as shown on the records of DTC or its participants. DTC serves as the securities depository for shares of the Fund. DTC participants include securities brokers and dealers, banks, trust companies, clearing corporations and other institutions that directly or indirectly maintain a custodial relationship with DTC. As a beneficial owner of shares, you are not entitled to receive physical delivery of stock certificates or to have shares registered in your name, and you are not considered a registered owner of shares. Therefore, to exercise any right as an owner of shares, you must rely upon the procedures of DTC and its participants. These procedures are the same as those that apply to any other securities that you hold in book-entry or “street name” form.

Share Prices. The trading prices of the Fund’s shares in the secondary market generally differ from the Fund’s daily NAV and are affected by market forces such as supply and demand, economic conditions and other factors. Information regarding the intraday value of shares of the Fund, also known as the “indicative optimized portfolio value” (“IOPV”), is disseminated every 15 seconds throughout the trading day by the national securities exchange on which the Fund’s shares are listed or by market data vendors or other information providers. The IOPV is based on the current market value of the securities and/or cash required to be deposited in exchange for a Creation Unit. The IOPV does not necessarily reflect the precise composition of the current portfolio of securities held by the Fund at a particular point in time or the best possible valuation of the current portfolio. Therefore, the IOPV should not be viewed as a “real-time” update of the Fund’s NAV, which is computed only once a day. The IOPV is generally determined by using both current market quotations and/or price quotations obtained from broker-dealers that may trade in the portfolio securities held by the Fund. The quotations of certain Fund holdings may not be updated during U.S. trading hours if such holdings do not trade in the United States. The Fund is not involved in, or responsible for, the calculation or dissemination of the IOPV and makes no representation or warranty as to its accuracy.

Determination of Net Asset Value. The NAV of the Fund normally is determined once daily Monday through Friday, generally as of the regularly scheduled close of business of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m., Eastern time) on each day that the NYSE is open for trading, based on prices at the time of closing provided that (a) any Fund assets or liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers (as detailed below) and (b) U.S. fixed income assets may be valued as of the announced closing time for trading in fixed income instruments in a particular market or exchange. The NAV

of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets held by the Fund, and its liabilities, are determined pursuant to valuation policies and procedures approved by the Board. The Fund’s assets and liabilities are valued primarily on the basis of market quotations.

Equity investments are valued at market value, which is generally determined using the last reported official closing price or last trading price on the exchange or market on which the security is primarily traded at the time of valuation.

The Fund invests in foreign securities. Foreign currency exchange rates are generally determined as of 4:00 p.m., London time. Foreign securities owned by the Fund may trade on weekends or other days when the Fund does not price its shares. As a result, the Fund’s NAV may change on days when Authorized Participants will not be able to purchase or redeem Fund shares.

Generally, trading in foreign securities, U.S. government securities, money market instruments and certain fixed-income securities is substantially completed each day at various times prior to the close of business on the NYSE. The values of such securities used in computing the NAV of the Fund are determined as of such times.

When market quotations are not readily available or are believed by BFA to be unreliable, the Fund’s investments are valued at fair value. Fair value determinations are made by BFA in accordance with policies and procedures approved by the Fund’s Board. BFA may conclude that a market quotation is not readily available or is unreliable if a security or other asset or liability does not have a price source due to its lack of liquidity, if a market quotation differs significantly from recent price quotations or otherwise no longer appears to reflect fair value, where the security or other asset or liability is thinly traded, or where there is a significant event subsequent to the most recent market quotation. A “significant event” is an event that, in the judgment of BFA, is likely to cause a material change to the closing market price of the asset or liability held by the Fund. Foreign securities whose values are affected by volatility that occurs in U.S. markets on a trading day after the close of foreign securities markets may be fair valued.

Fair value represents a good faith approximation of the value of an asset or liability. The fair value of an asset or liability held by the Fund is the amount the Fund might reasonably expect to receive from the current sale of that asset or the cost to extinguish that liability in an arm’s-length transaction. Valuing the Fund’s investments using fair value pricing will result in prices that may differ from current market valuations and that may not be the price at which those investments could have been sold during the period in which the particular fair values were used. Use of fair value prices and certain current market valuations could result in a difference between the prices used to calculate the Fund’s NAV and the prices used by the Underlying Index, which, in turn, could result in a difference between the Fund’s performance and the performance of the Underlying Index.

The value of assets or liabilities denominated in non-U.S. currencies will be converted into U.S. dollars using exchange rates deemed appropriate by BFA as investment

adviser. Use of a rate different from the rate used by the Index Provider may adversely affect the Fund’s ability to track the Underlying Index.

Dividends and Distributions

General Policies. Dividends from net investment income, if any, generally are declared and paid semi-annually by the Fund. Distributions of net realized securities gains, if any, generally are declared and paid once a year, but the Trust may make distributions on a more frequent basis for the Fund. The Trust reserves the right to declare special distributions if, in its reasonable discretion, such action is necessary or advisable to preserve its status as a regulated investment company (“RIC”) or to avoid imposition of income or excise taxes on undistributed income or realized gains.

Dividends and other distributions on shares of the Fund are distributed on a pro rata basis to beneficial owners of such shares. Dividend payments are made through DTC participants and indirect participants to beneficial owners then of record with proceeds received from the Fund.

Dividend Reinvestment Service. No dividend reinvestment service is provided by the Trust. Broker-dealers may make available the DTC book-entry Dividend Reinvestment Service for use by beneficial owners of the Fund for reinvestment of their dividend distributions. Beneficial owners should contact their broker to determine the availability and costs of the service and the details of participation therein. Brokers may require beneficial owners to adhere to specific procedures and timetables. If this service is available and used, dividend distributions of both income and realized gains will be automatically reinvested in additional whole shares of the Fund purchased in the secondary market.

Taxes. As with any investment, you should consider how your investment in shares of the Fund will be taxed. The tax information in this Prospectus is provided as general information, based on current law. You should consult your own tax professional about the tax consequences of an investment in shares of the Fund.

Unless your investment in Fund shares is made through a tax-exempt entity or tax-deferred retirement account, such as an IRA, you need to be aware of the possible tax consequences when the Fund makes distributions or you sell Fund shares.

Taxes on Distributions. Distributions from the Fund’s net investment income (other than qualified dividend income), including distributions of income from securities lending and distributions out of the Fund’s net short-term capital gains, if any, are taxable to you as ordinary income. Distributions by the Fund of net long-term capital gains in excess of net short-term capital losses (capital gain dividends) are taxable to you as long-term capital gains, generally at a 15% tax rate (0% at certain income levels), regardless of how long you have held the Fund’s shares. Distributions by the Fund that qualify as qualified dividend income are taxable to you at long-term capital gain rates for taxable years beginning on or before December 31, 2012. The 15% and 0% tax rates expire for taxable years beginning after December 31, 2012. Maximum long-term capital gain income tax rates are scheduled to rise to 20% in 2013. Beginning in 2013, a 3.8% U.S. federal Medicare contribution tax will be imposed on “net investment income,” including interest, dividends, and capital gains, of U.S.

individuals with income exceeding $200,000 (or $250,000 if married and filing jointly), and of estates and trusts.

Dividends will be qualified dividend income to you if they are attributable to qualified dividend income received by the Fund. Generally, qualified dividend income includes dividend income from taxable U.S. corporations and qualified non-U.S. corporations, provided that the Fund satisfies certain holding period requirements in respect of the stock of such corporations and has not hedged its position in the stock in certain ways. Substitute dividends received by the Fund with respect to dividends paid on securities lent out will not be qualified dividend income. For this purpose, a qualified non-U.S. corporation means any non-U.S. corporation that is eligible for benefits under a comprehensive income tax treaty with the United States, which includes an exchange of information program or if the stock with respect to which the dividend was paid is readily tradable on an established United States securities market. The term excludes a corporation that is a passive foreign investment company.

Dividends received by the Fund from a real estate investment trust (“REIT”) or another RIC generally are qualified dividend income only to the extent the dividend distributions are made out of qualified dividend income received by such REIT or RIC. It is expected that dividends received by the Fund from a REIT and distributed to a shareholder generally will be taxable to the shareholder as ordinary income.

For a dividend to be treated as qualified dividend income, the dividend must be received with respect to a share of stock held without being hedged by the Fund, and with respect to a share of the Fund held without being hedged by you, for 61 days during the 121-day period beginning at the date which is 60 days before the date on which such share becomes ex-dividend with respect to such dividend or, in the case of certain preferred stock, 91 days during the 181-day period beginning 90 days before such date.

If your Fund shares are loaned out pursuant to a securities lending arrangement, you may lose the ability to use foreign tax credits passed through by the Fund or to treat Fund dividends paid while the shares are held by the borrower as qualified dividend income.

In general, your distributions are subject to U.S. federal income tax for the year when they are paid. Certain distributions paid in January, however, may be treated as paid on December 31 of the prior year.

If the Fund’s distributions exceed current and accumulated earnings and profits, all or a portion of the distributions made in the taxable year may be recharacterized as a return of capital to shareholders. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and result in a higher capital gain or lower capital loss when those shares on which the distribution was received are sold. Once a shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain, if the shareholder holds shares of the Fund as capital assets.

If you are neither a resident nor a citizen of the United States or if you are a non-U.S. entity, the Fund’s ordinary income dividends (which include distributions of net short-term capital gains) will generally be subject to a 30% U.S. withholding tax, unless a lower treaty rate applies, provided that withholding tax will generally not apply to any

gain or income realized by a non-U.S. shareholder in respect of any distributions of long-term capital gains or upon the sale or other disposition of shares of the Fund.

A 30% withholding tax will be imposed on dividends paid after December 31, 2013, and redemption proceeds paid after December 31, 2014, to (i) foreign financial institutions including non-U.S. investment funds unless they agree to collect and disclose to the Internal Revenue Service (“IRS”) information regarding their direct and indirect U.S. account holders and (ii) certain other foreign entities, unless they certify certain information regarding their direct and indirect U.S. owners. To avoid withholding, foreign financial institutions will need to enter into agreements with the IRS that state that they will provide the IRS information, including the name, address and taxpayer identification number of direct and indirect U.S. account holders, comply with due diligence procedures with respect to the identification of U.S. accounts, report to the IRS certain information with respect to U.S. accounts maintained, agree to withhold tax on certain payments made to non-compliant foreign financial institutions or to account holders who fail to provide the required information, and determine certain other information as to their account holders. Other foreign entities will need to provide the name, address, and taxpayer identification number of each substantial U.S. owner or certifications of no substantial U.S. ownership unless certain exceptions apply.

Dividends, interest and capital gains earned by the Fund with respect to non-U.S. securities may give rise to withholding and other taxes imposed by non-U.S. countries. Tax conventions between certain countries and the United States may reduce or eliminate such taxes. If more than 50% of the total assets of the Fund at the close of a year consists of non-U.S. stocks or securities, the Fund may “pass through” to you certain non-U.S. income taxes (including withholding taxes) paid by the Fund. This means that you would be considered to have received as an additional dividend your share of such non-U.S. taxes, but you may be entitled to either a corresponding tax deduction in calculating your taxable income, or, subject to certain limitations, a credit in calculating your U.S. federal income tax.

For purposes of foreign tax credits for U.S. shareholders of the Fund, foreign capital gains taxes may not produce associated foreign source income, thereby limiting a U.S. person’s ability to use such credits.

If you are a resident or a citizen of the United States, by law, back-up withholding will apply to your distributions and proceeds if you have not provided a taxpayer identification number or social security number and made other required certifications.

Taxes When Shares are Sold. Currently, any capital gain or loss realized upon a sale of Fund shares is generally treated as a long-term gain or loss if the shares have been held for more than one year. Any capital gain or loss realized upon a sale of Fund shares held for one year or less is generally treated as short-term gain or loss, except that any capital loss on the sale of shares held for six months or less is treated as long-term capital loss to the extent that capital gain dividends were paid with respect to such shares. Beginning in 2013, any such capital gains, including from sales of Fund shares or from capital gain dividends, will be included in “net investment income” for purposes of the 3.8% U.S. federal Medicare contribution tax mentioned above.

The foregoing discussion summarizes some of the consequences under current U.S. federal tax law of an investment in the Fund. It is not a substitute for personal tax advice. You may also be subject to state and local taxation on Fund distributions and sales of shares. Consult your personal tax adviser about the potential tax consequences of an investment in shares of the Fund under all applicable tax laws.

Creations and Redemptions. Prior to trading in the secondary market, shares of the Fund are “created” at NAV by market makers, large investors and institutions only in block-size Creation Units of 50,000 shares or multiples thereof. Each “creator” or “Authorized Participant” enters into an authorized participant agreement with the Fund’s distributor, SEI Investments Distribution Co. (the “Distributor”). Only an Authorized Participant may create or redeem Creation Units directly with the Fund. A creation transaction, which is subject to acceptance by the transfer agent, generally takes place when an Authorized Participant deposits into the Fund a designated portfolio of securities and a specified amount of cash approximating the holdings of the Fund in exchange for a specified number of Creation Units. To the extent practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund.

Similarly, shares can be redeemed only in Creation Units, generally for a designated portfolio of securities and a specified amount of cash held by the Fund (“Fund Securities”). Except when aggregated in Creation Units, shares are not redeemable by the Fund. The prices at which creations and redemptions occur are based on the next calculation of NAV after an order is received in a form described in the authorized participant agreement.

The Fund intends to comply with the U.S. federal securities laws in accepting securities for deposit and satisfying redemptions with redemption securities by, among other means, assuring that any securities accepted for deposit and any securities used to satisfy redemption requests will be sold in transactions that would be exempt from registration under the Securities Act of 1933, as amended (the “1933 Act”). Further, an Authorized Participant that is not a “qualified institutional buyer,” as such term is defined under Rule 144A of the 1933 Act, will not be able to receive Fund Securities that are restricted securities eligible for resale under Rule 144A.

Creations and redemptions must be made through a firm that is either a member of the Continuous Net Settlement System of the National Securities Clearing Corporation or a DTC participant and has executed an agreement with the Distributor with respect to creations and redemptions of Creation Unit aggregations. Information about the procedures regarding creation and redemption of Creation Units (including the cut-off times for receipt of creation and redemption orders) is included in the Fund’s SAI.

Because new shares may be created and issued on an ongoing basis, at any point during the life of the Fund a “distribution,” as such term is used in the 1933 Act, may be occurring. Broker-dealers and other persons are cautioned that some activities on their part may, depending on the circumstances, result in their being deemed participants in a distribution in a manner that could render them statutory underwriters and subject to the prospectus delivery and liability provisions of the 1933 Act. Any determination of whether one is an underwriter must take into account all the relevant facts and circumstances of each particular case.

Broker-dealers should also note that dealers who are not “underwriters” but are participating in a distribution (as contrasted to ordinary secondary transactions), and thus dealing with shares that are part of an “unsold allotment” within the meaning of Section 4(3)(C) of the 1933 Act, would be unable to take advantage of the prospectus delivery exemption provided by Section 4(3) of the 1933 Act. For delivery of prospectuses to exchange members, the prospectus delivery mechanism of Rule 153 under the 1933 Act is available only with respect to transactions on a national securities exchange.

Costs Associated with Creations and Redemptions. Authorized Participants are charged standard creation and redemption transaction fees to offset transfer and other transaction costs associated with the issuance and redemption of Creation Units. The standard creation and redemption transaction fees are set forth in the table below. The standard creation transaction fee is charged to the Authorized Participant on the day such Authorized Participant creates a Creation Unit, and is the same regardless of the number of Creation Units purchased by the Authorized Participant on the applicable business day. Similarly, the standard redemption transaction fee is charged to the Authorized Participant on the day such Authorized Participant redeems a Creation Unit, and is the same regardless of the number of Creation Units redeemed by the Authorized Participant on the applicable business day. Creations and redemptions for cash (when cash creations and redemptions (in whole or in part) are available or specified) are also subject to an additional charge (up to the maximum amounts shown in the table below). This charge is intended to compensate for brokerage, tax, foreign exchange, execution, market impact and other costs and expenses related to cash transactions. Investors who use the services of a broker or other financial intermediary may pay fees for such services.

The following table shows, as of September 30, 2011, the approximate value of one Creation Unit, standard fees and maximum additional charges for creations and redemptions (as described above):

Householding. Householding is an option available to certain Fund investors. Householding is a method of delivery, based on the preference of the individual investor, in which a single copy of certain shareholder documents can be delivered to investors who share the same address, even if their accounts are registered under different names. Please contact your broker-dealer if you are interested in enrolling in householding and receiving a single copy of prospectuses and other shareholder documents, or if you are currently enrolled in householding and wish to change your householding status.

Distribution

The Distributor distributes Creation Units for the Fund on an agency basis. The Distributor does not maintain a secondary market in shares of the Fund. The Distributor has no role in determining the policies of the Fund or the securities that are purchased or sold by the Fund. The Distributor’s principal address is One Freedom Valley Drive, Oaks, PA 19456.

In addition, BFA or its Affiliates make payments to broker-dealers, banks or other financial intermediaries (together, “intermediaries”) related to marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems, or their making shares of the Fund and certain other iShares funds available to their customers. Such payments, which may be significant to the intermediary, are not made by the Fund. Rather, such payments are made by BFA or its Affiliates from their own resources, which come directly or indirectly in part from fees paid by the iShares funds complex. Payments of this type are sometimes referred to as revenue-sharing payments. A financial intermediary may make decisions about which investment options it recommends or makes available, or the level of services provided, to its customers based on the revenue-sharing payments it is eligible to receive. Therefore, such payments to an intermediary create conflicts of interest between the intermediary and its customers and may cause the intermediary to recommend the Fund or other iShares funds over another investment. More information regarding these payments is contained in the Fund’s SAI. Please contact your salesperson or other investment professional for more information regarding any such payments his or her firm may receive from BFA or its Affiliates.

Financial Highlights

The financial highlights table is intended to help investors understand the Fund’s financial performance since inception. Certain information reflects financial results for a single share of the Fund. The total returns in the table represent the rate that an investor would have earned (or lost) on an investment in the Fund, assuming reinvestment of all dividends and distributions. This information has been audited by PricewaterhouseCoopers LLP, whose report is included, along with the Fund’s financial statements, in the Fund’s Annual Report (available upon request).

Supplemental Information

I. Premium/Discount Information

The table that follows presents information about the differences between the daily market price on secondary markets for shares of the Fund and the Fund’s NAV. NAV is the price at which the Fund issues and redeems shares. It is calculated in accordance with the standard formula for valuing mutual fund shares. The price used to calculate market returns (“Market Price”) of the Fund generally is determined using the midpoint between the highest bid and the lowest offer on the primary securities exchange on which shares of the Fund are listed for trading, as of the time that the Fund’s NAV is calculated. The Fund’s Market Price may be at, above or below its NAV. The NAV of the Fund will fluctuate with changes in the value of its portfolio holdings. The Market Price of the Fund will fluctuate in accordance with changes in its NAV, as well as market supply and demand.

Premiums or discounts are the differences (expressed as a percentage) between the NAV and Market Price of the Fund on a given day, generally at the time the NAV is calculated. A premium is the amount that the Fund is trading above the reported NAV, expressed as a percentage of the NAV. A discount is the amount that the Fund is trading below the reported NAV, expressed as a percentage of the NAV.

The following information shows the frequency of distributions of premiums and discounts for the Fund from October 1, 2010 through September 30, 2011.

Each line in the table shows the number of trading days in which the Fund traded within the premium/discount range indicated. The number of trading days in each premium/discount range is also shown as a percentage of the total number of trading days in the period covered by the table. All data presented here represents past performance, which cannot be used to predict future results.

II. Total Return Information

The table that follows presents information about the total returns of the Fund and the Underlying Index as of the fiscal year ended July 31, 2011.

“Average Annual Total Returns” represent the average annual change in value of an investment over the periods indicated. “Cumulative Total Returns” represent the total change in value of an investment over the period indicated.

The Fund’s NAV is the value of one share of the Fund as calculated in accordance with the standard formula for valuing mutual fund shares. The NAV return is based on the NAV of the Fund and the market return is based on the Market Price of the Fund. Market Price is determined by using the midpoint between the highest bid and the lowest offer on the primary stock exchange on which shares of the Fund are listed for trading, as of the time that the Fund’s NAV is calculated. Since shares of the Fund did not trade in the secondary market until after the Fund’s inception, for the period from inception to the first day of secondary market trading in shares of the Fund, the NAV of the Fund is used as a proxy for the Market Price to calculate market returns. Market and NAV returns assume that dividends and capital gain distributions have been reinvested in the Fund at Market Price and NAV, respectively.

An index is a statistical composite that tracks a specified financial market or sector. Unlike the Fund, the Underlying Index does not actually hold a portfolio of securities and therefore does not incur the expenses incurred by the Fund. These expenses negatively impact the performance of the Fund. Also, market returns do not include brokerage commissions that may be payable on secondary market transactions. If brokerage commissions were included, market returns would be lower. The returns shown in the following table do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption or sale of Fund shares. The investment return and principal value of shares of the Fund will vary with changes in market conditions. Shares of the Fund may be worth more or less than their original cost when they are redeemed or sold in the market. The Fund’s past performance is no guarantee of future results.

Fund Overview

iSHARES® MSCI ACWI ex US TELECOMMUNICATION SERVICES SECTOR INDEX FUND

Ticker: AXTE Stock Exchange: NYSE Arca

Investment Objective

The iShares MSCI ACWI ex US Telecommunication Services Sector Index Fund (the “Fund”) seeks investment results that correspond generally to the price and yield performance, before fees and expenses, of the MSCI All Country World ex USA Telecommunication Services Index (the “Underlying Index”).

Fees and Expenses

The following table describes the fees and expenses that you will incur if you own shares of the Fund. The investment advisory agreement between iShares Trust (the “Trust”) and BlackRock Fund Advisors (“BFA”) (the “Investment Advisory Agreement”) provides that BFA will pay all operating expenses of the Fund, except interest expenses, taxes, brokerage expenses, future distribution fees or expenses, and extraordinary expenses.

You may also incur usual and customary brokerage commissions when buying or selling shares of the Fund, which are not reflected in the example that follows:

Annual Fund Operating Expenses

Example. This Example is intended to help you compare the cost of owning shares of the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

Portfolio Turnover. The Fund may pay transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 5% of the average value of its portfolio.

Principal Investment Strategies

The Underlying Index is a free float-adjusted market capitalization-weighted index designed to measure the combined equity market performance of the telecommunication sector of developed and emerging markets countries, excluding the United States. Component securities include those of diversified telecommunication and wireless telecommunication companies. As of September 30, 2011, the Underlying Index consisted of companies in the following countries or regions: Australia, Austria, Belgium, Brazil, Canada, Chile, China, Colombia, the Czech Republic, Denmark, Egypt, Finland, France, Germany, Greece, Hong Kong, Hungary, India, Indonesia, Ireland, Israel, Italy, Japan, Malaysia, Mexico, Morocco, the Netherlands, New Zealand, Norway, Peru, the Philippines, Poland, Portugal, Russia, Singapore, South Africa, South Korea, Spain, Sweden, Switzerland, Taiwan, Thailand, Turkey and the United Kingdom (together, the “ACWI ex US telecommunication services sector countries”). As of September 30, 2011, the Underlying Index was comprised of 85 securities.

BFA uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to “beat” the index it tracks and does not seek temporary defensive positions when markets decline or appear overvalued.

Indexing may eliminate the chance that the Fund will substantially outperform the Underlying Index but also may reduce some of the risks of active management, such as poor security selection. Indexing seeks to achieve lower costs and better after-tax performance by keeping portfolio turnover low in comparison to actively managed investment companies.

BFA uses a representative sampling indexing strategy to manage the Fund. “Representative sampling” is an indexing strategy that involves investing in a representative sample of securities that collectively has an investment profile similar to the Underlying Index. The securities selected are expected to have, in the aggregate, investment characteristics (based on factors such as market capitalization and industry weightings), fundamental characteristics (such as return variability and yield) and liquidity measures similar to those of the Underlying Index. The Fund may or may not hold all of the securities in the Underlying Index.

The Fund generally invests at least 80% of its assets in securities of the Underlying Index or in depositary receipts representing securities of the Underlying Index. The Fund may invest the remainder of its assets in securities not included in the Underlying Index,

S-2   


Table Of Contents



but which BFA believes will help the Fund track the Underlying Index and in other investments including futures contracts, options on futures contracts, options and swaps related to the Underlying Index, as well as cash and cash equivalents, including shares of money market funds advised by BFA or its affiliates.

The Fund may lend securities representing up to one-third of the value of the Fund’s total assets (including the value of the collateral received).

The Underlying Index is sponsored by an organization (the “Index Provider”) that is independent of the Fund and BFA. The Index Provider determines the composition and relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index. The Fund’s Index Provider is MSCI Inc. (“MSCI”).

Industry Concentration Policy. The Fund will concentrate its investments (i.e., hold 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. For purposes of this limitation, securities of the U.S. government (including its agencies and instrumentalities) and repurchase agreements collateralized by U.S. government securities are not considered to be issued by members of any industry.

Summary of Principal Risks

As with any investment, you could lose all or part of your investment in the Fund, and the Fund’s performance could trail that of other investments. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund’s net asset value per share (“NAV”), trading price, yield, total return and ability to meet its investment objective.

Asset Class Risk. Securities in the Underlying Index or in the Fund’s portfolio may underperform in comparison to the general securities markets or other asset classes.

Commodity Risk. The Fund invests in economies that are susceptible to fluctuations in certain commodity markets. Any negative changes in commodity markets could have an adverse impact on those economies.

Concentration Risk. To the extent that the Fund’s investments are concentrated in a particular issuer, region, country, market, industry or asset class, the Fund may be susceptible to loss due to adverse occurrences affecting that issuer, region, country, market, industry or asset class.

Currency Risk. Because the Fund’s NAV is determined in U.S. dollars, the Fund’s NAV could decline if the currency of a non-U.S. market in which the Fund invests depreciates against the U.S. dollar.

Custody Risk. Less developed markets are more likely to experience problems with the clearing and settling of trades and the holding of securities by local banks, agents and depositories.

Emerging Markets Risk. The Fund’s investments in emerging markets may be subject to a greater risk of loss than investments in more developed markets. Emerging markets may be more likely to experience inflation risk, political turmoil and rapid changes in economic conditions than more

S-3   


Table Of Contents



developed markets. Emerging markets often have less uniformity in accounting and reporting requirements, unreliable securities valuation and greater risk associated with custody of securities.

Equity Securities Risk. Equity securities are subject to changes in value and their values may be more volatile than other asset classes.

Geographic Risk. A natural or other disaster could occur in a geographic region in which the Fund invests, which could affect the economy or particular business operations of companies in the specific geographic region, causing an adverse impact on the Fund’s investments in the affected region.

Issuer Risk. Fund performance depends on the performance of individual securities to which the Fund has exposure. Changes to the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA’s investment management strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares, losses from trading in secondary markets, periods of high volatility and disruption in the creation/redemption process of the Fund. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV.

Non-Diversification Risk. The Fund may invest a large percentage of its assets in securities issued by or representing a small number of issuers. As a result, the Fund’s performance may depend on the performance of a small number of issuers.

Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers are subject to the risks associated with investing in those non-U.S. markets, such as heightened risks of inflation or nationalization. The Fund may lose money due to political, economic and geographic events affecting a non-U.S. issuer or market. The Fund is specifically exposed to Asian Economic Risk and European Economic Risk.

Passive Investment Risk. The Fund is not actively managed and BFA does not attempt to take defensive positions under any market conditions, including declining markets.

Privatization Risk. Some countries in which the Fund invests have begun a process of privatizing certain entities and industries. Privatized entities may lose money or be re-nationalized.

Reliance on Trading Partners Risk. The Fund invests in countries whose economies are heavily dependent upon trading with key partners. Any reduction in this trading may have an adverse impact on the Fund’s investments. Through its trading partners, the Fund is particularly exposed to U.S. Trading Partner Risk.

Securities Lending Risk. The Fund may engage in securities lending. Securities lending involves the risk that the Fund may lose money because the borrower

S-4   


Table Of Contents



of the Fund’s loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Security Risk. Some countries and regions in which the Fund invests have experienced security concerns. Incidents involving a country’s or region’s security may cause uncertainty in these markets and may adversely affect their economies and the Fund’s investments.

Structural Risk. The countries in which the Fund invests may be subject to considerable degrees of economic, political and social instability.

Telecommunications Sector Risk. Companies in the telecommunications sector may be affected by industry competition, substantial capital requirements, government regulation and obsolescence of telecommunications products and services due to technological advancement.

Tracking Error Risk. The performance of the Fund may diverge from that of the Underlying Index. Because the Fund employs a representative sampling strategy, the Fund may experience tracking error to a greater extent than a fund that seeks to replicate an index.

Valuation Risk. The value of the securities in the Fund’s portfolio may change on days when shareholders will not be able to purchase or sell the Fund’s shares.

Performance Information

As of the date of the Fund’s prospectus (the “Prospectus”), the Fund has been in operation for less than one full calendar year and therefore does not report its performance information.

Management

Investment Adviser. BlackRock Fund Advisors.

Portfolio Managers. Rene Casis, Diane Hsiung and Greg Savage (the “Portfolio Managers”) are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager supervises a portfolio management team. Mr. Casis has been a Portfolio Manager of the Fund since 2010. Ms. Hsiung and Mr. Savage have been Portfolio Managers of the Fund since inception.

Purchase and Sale of Fund Shares

The Fund is an exchange-traded fund (commonly referred to as an “ETF”). Individual Fund shares may only be purchased and sold on a national securities exchange through a broker-dealer. The price of Fund shares is based on market price, and because ETF shares trade at market prices rather than NAV, shares may trade at a price greater than NAV (a premium) or less than NAV (a discount). The Fund will only issue or redeem shares that have been aggregated into blocks of 50,000 shares or multiples thereof (“Creation Units”) to authorized participants who have entered into agreements with the Fund’s distributor. The Fund generally will issue or redeem Creation Units in return for a designated portfolio of securities (and an amount of cash) that the Fund specifies each day.

Tax Information

The Fund intends to make distributions that may be taxable to you as ordinary income or capital gains, unless you are investing through a tax-deferred arrangement such as a 401(k) plan or an individual retirement account (“IRA”).

Payments to Broker-Dealers and other Financial Intermediaries

If you purchase shares of the Fund through a broker-dealer or other financial intermediary (such as a bank), BFA or other related companies may pay the intermediary for marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems or other services related to the sale or promotion of the Fund. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.

More Information About the Fund

This Prospectus contains important information about investing in the Fund. Please read this Prospectus carefully before you make any investment decisions. Additional information regarding the Fund is available at www.iShares.com.

BFA is the investment adviser to the Fund. Shares of the Fund are listed for trading on NYSE Arca, Inc. (“NYSE Arca”). The market price for a share of the Fund may be different from the Fund’s most recent NAV.

ETFs are funds that trade like other publicly-traded securities. The Fund is designed to track an index. Similar to shares of an index mutual fund, each share of the Fund represents a partial ownership in an underlying portfolio of securities intended to track a market index. Unlike shares of a mutual fund, which can be bought and redeemed from the issuing fund by all shareholders at a price based on NAV, shares of the Fund may be purchased or redeemed directly from the Fund at NAV solely by authorized participants. Also unlike shares of a mutual fund, shares of the Fund are listed on a national securities exchange and trade in the secondary market at market prices that change throughout the day.

The Fund invests in a particular segment of the securities markets and seeks to track the performance of a securities index that generally is not representative of the market as a whole. The Fund is designed to be used as part of broader asset allocation strategies. Accordingly, an investment in the Fund should not constitute a complete investment program.

An index is a theoretical financial calculation while the Fund is an actual investment portfolio. The performance of the Fund and the Underlying Index may vary due to transaction costs, non-U.S. currency valuations, asset valuations, corporate actions (such as mergers and spin-offs), timing variances and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions (such as diversification requirements) that apply to the Fund but not to the Underlying Index or to the use of representative sampling. “Tracking error” is the difference between the performance (return) of the Fund’s portfolio and that of the Underlying Index. BFA expects that, over time, the Fund’s tracking error will not exceed 5%. Because the Fund uses a representative sampling indexing strategy, it can be expected to have a larger tracking error than if it used a replication indexing strategy. “Replication” is an indexing strategy in which a fund invests in substantially all of the securities in its underlying index in approximately the same proportions as in the underlying index.

An investment in the Fund is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, BFA or any of its affiliates.

The Fund’s investment objective and the Underlying Index may be changed without shareholder approval.

A Further Discussion of Principal Risks

The Fund is subject to various risks, including the principal risks noted below, any of which may adversely affect the Fund’s NAV, trading price, yield, total return and ability to meet its investment objective. You could lose all or part of your investment in the Fund, and the Fund could underperform other investments.

Asian Economic Risk. Certain Asian economies have experienced over-extension of credit, currency devaluations and restrictions, high unemployment, high inflation, decreased exports and economic recessions. Economic events in any one Asian country may have a significant economic effect on the entire Asian region, as well as on major trading partners outside Asia, and any adverse event in the Asian markets may have a significant adverse effect on some or all of the ACWI ex US telecommunication services sector countries.

Asset Class Risk. The securities in the Underlying Index or in the Fund’s portfolio may underperform the returns of other securities or indexes that track other countries, groups of countries, regions, industries, groups of industries, markets, asset classes or sectors. Various types of securities or indexes tend to experience cycles of outperformance and underperformance in comparison to the general securities markets.

Commodity Risk. Economies and companies whose performance is reflected in the Fund’s portfolio or Underlying Index may be adversely affected by changes or trends in commodity prices. Commodity prices may be influenced or characterized by unpredictable factors, including, where applicable, high volatility, changes in supply and demand relationships, weather, agriculture, trade, pestilence, political instability, changes in interest rates and monetary and other governmental policies, action and inaction. Securities of companies held by the Fund that are dependent on a single commodity, or are concentrated in a single commodity sector, may typically exhibit even higher volatility attributable to commodity prices.

Concentration Risk. To the extent that the Fund’s portfolio reflects the Underlying Index’s concentration in the securities of a particular issuer or issuers in a particular country, group of countries, region, market, industry, group of industries, sector or asset class, the Fund may be adversely affected by the performance of those securities, may be subject to increased price volatility and may be more susceptible to adverse economic, market, political or regulatory occurrences affecting that issuer, country, group of countries, region, market, industry, group of industries, sector or asset class.

Currency Risk. Because the Fund’s NAV is determined on the basis of the U.S. dollar, investors may lose money if the currency of a non-U.S. market in which the Fund invests depreciates against the U.S. dollar, even if the local currency value of the Fund’s holdings in that market increases.



Custody Risk. Custody risk refers to the risks inherent in the process of clearing and settling trades and the holding of securities by local banks, agents and depositories. Low trading volumes and volatile prices in less developed markets may make trades harder to complete and settle, and governments or trade groups may compel local agents to hold securities in designated depositories that are not subject to

independent evaluation. Local agents are held only to the standards of care of their local markets. In general, the less developed a country’s securities market is, the greater the likelihood of custody problems.

Emerging Markets Risk. Investments in emerging markets are subject to a greater risk of loss than investments in more developed markets. This is due to, among other things, the potential for greater market volatility, lower trading volume, inflation, political and economic instability, greater risk of a market shutdown and more governmental limitations on foreign investments than typically found in more developed markets. In addition, emerging markets often have less uniformity in accounting and reporting requirements, unreliable securities valuation and greater risks associated with custody of securities.

Equity Securities Risk. The Fund invests in equity securities, which are subject to changes in value that may be attributable to market perception of a particular issuer or to general stock market fluctuations that affect all issuers. Investments in equity securities may be more volatile than investments in other asset classes.

European Economic Risk. The Economic and Monetary Union of the European Union (the “EU”) requires member countries to comply with restrictions on inflation rates, deficits, interest rates, debt levels and fiscal and monetary controls, each of which may significantly affect every country in Europe. Decreasing imports or exports, changes in governmental or EU regulations on trade, changes in the exchange rate of the euro, the default or threat of default by an EU member country on its sovereign debt, and/or an economic recession in an EU member country may have a significant adverse effect on the economies of EU member countries and their trading partners, including some or all of the ACWI ex US telecommunication services sector countries. The European financial markets have recently experienced volatility and have been adversely affected by concerns about economic downturns, credit rating downgrades, rising government debt levels and possible default on or restructuring of government debt in several European countries, including Greece, Ireland, Italy, Portugal and Spain. A default or debt restructuring by any European country would adversely impact holders of that country’s debt, and sellers of credit default swaps linked to that country’s creditworthiness, which may be located in countries other than those listed in the previous sentence. These events have adversely affected the value and exchange rate of the euro and may continue to significantly affect the economies of every country in Europe, including EU member countries that do not use the euro and non-EU member countries.

Geographic Risk. Some markets in which the Fund invests are located in parts of the world that have historically been prone to natural disasters, such as earthquakes, volcanoes, droughts, floods, hurricanes and tsunamis, and are economically sensitive to environmental events. Any natural or other disaster could have a significant adverse impact on the economies of these geographic areas, causing an adverse impact on the Fund’s investments in the affected region.

Issuer Risk. The performance of the Fund depends on the performance of individual securities to which the Fund has exposure. Any issuer of these securities may perform poorly, causing the value of its securities to decline. Poor performance may be caused by poor management decisions, competitive pressures, changes in technology,

expiration of patent protection, disruptions in supply, labor problems or shortages, corporate restructurings, fraudulent disclosures or other factors. Issuers may, in times of distress or at their own discretion, decide to reduce or eliminate dividends, which may also cause their stock prices to decline.

Management Risk. The Fund may not fully replicate the Underlying Index and may hold securities not included in the Underlying Index. As a result, the Fund is subject to the risk that BFA’s investment management strategy, the implementation of which is subject to a number of constraints, may not produce the intended results.

Market Risk. The Fund could lose money due to short-term market movements and over longer periods during market downturns. Securities may decline in value due to factors affecting securities markets generally or particular industries represented in the markets. The value of a security may decline due to general market conditions, economic trends or events that are not specifically related to the issuer of the security or to factors that affect a particular industry or industries. During a general downturn in the securities markets, multiple asset classes may be negatively affected.

Market Trading Risk

Absence of Active Market. Although shares of the Fund are listed for trading on one or more stock exchanges, there can be no assurance that an active trading market for such shares will develop or be maintained.

Risk of Secondary Listings. The Fund’s shares may be listed or traded on U.S. and non-U.S. stock exchanges other than the U.S. stock exchange where the Fund’s primary listing is maintained. There can be no assurance that the Fund’s shares will continue to trade on any such stock exchange or in any market or that the Fund’s shares will continue to meet the requirements for listing or trading on any exchange or in any market. The Fund’s shares may be less actively traded in certain markets than others, and investors are subject to the execution and settlement risks and market standards of the market where they or their broker direct their trades for execution. Certain information available to investors who trade Fund shares on a U.S. stock exchange during regular U.S. market hours may not be available to investors who trade in other markets, which may result in secondary market prices in such markets being less efficient.

Secondary Market Trading Risk. Shares of the Fund may trade in the secondary market at times when the Fund does not accept orders to purchase or redeem shares. At such times, shares may trade in the secondary market with more significant premiums or discounts than might be experienced at times when the Fund accepts purchase and redemption orders.

Secondary market trading in Fund shares may be halted by a stock exchange because of market conditions or other reasons. In addition, trading in Fund shares on a stock exchange or in any market may be subject to trading halts caused by extraordinary market volatility pursuant to “circuit breaker” rules on the stock exchange or market. There can be no assurance that the requirements necessary to maintain the listing or trading of Fund shares will continue to be met or will remain unchanged.

Shares of the Fund May Trade at Prices Other Than NAV. Shares of the Fund trade on stock exchanges at prices at, above or below their most recent NAV. The NAV of the

Fund is calculated at the end of each business day and fluctuates with changes in the market value of the Fund’s holdings since the most recent calculation. The trading prices of the Fund’s shares fluctuate continuously throughout trading hours based on market supply and demand rather than NAV. The trading prices of the Fund’s shares may deviate significantly from NAV during periods of market volatility. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV. However, because shares can be created and redeemed in Creation Units at NAV (unlike shares of many closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their NAVs), BFA believes that large discounts or premiums to the NAV of the Fund are not likely to be sustained over the long-term. While the creation/redemption feature is designed to make it likely that the Fund’s shares normally will trade on stock exchanges at prices close to the Fund’s next calculated NAV, exchange prices are not expected to correlate exactly with the Fund’s NAV due to timing reasons as well as market supply and demand factors. In addition, disruptions to creations and redemptions or extreme market volatility may result in trading prices for shares of the Fund that differ significantly from its NAV.

Costs of Buying or Selling Fund Shares. Buying or selling Fund shares on an exchange involves two types of costs that apply to all securities transactions. When buying or selling shares of the Fund through a broker, you will likely incur a brokerage commission or other charges imposed by brokers as determined by that broker. In addition, you may incur the cost of the “spread” – that is, the difference between what investors are willing to pay for Fund shares (the “bid” price) and the price at which they are willing to sell Fund shares (the “ask” price). Because of the costs inherent in buying or selling Fund shares, frequent trading may detract significantly from investment results and an investment in Fund shares may not be advisable for investors who anticipate regularly making small investments.

Non-Diversification Risk. The Fund is classified as “non-diversified.” This means that the Fund may invest a large percentage of its assets in securities issued by or representing a small number of issuers. As a result, the Fund may be more susceptible to the risks associated with these particular issuers, or to a single economic, political or regulatory occurrence affecting these issuers.

Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers are subject to all of the risks of investing in the markets where such issuers are located, including heightened risks of inflation or nationalization and market fluctuations caused by economic and political developments. As a result of investing in non-U.S. securities, the Fund may be subject to increased risk of loss caused by any of the factors listed below:

  • Lower levels of liquidity and market efficiency;
  • Greater securities price volatility;
  • Exchange rate fluctuations and exchange controls;
  • Less availability of public information about issuers;
  • Limitations on foreign ownership of securities;
  • Imposition of withholding or other taxes;
  • Imposition of restrictions on the expatriation of the funds or other assets of the Fund;
  • Higher transaction and custody costs and delays in settlement procedures;
  • Difficulties in enforcing contractual obligations;
  • Lower levels of regulation of the securities market;
  • Weaker accounting, disclosure and reporting requirements; and
  • Legal principles related to corporate governance, directors’ fiduciary duties and liabilities and stockholders’ rights in markets in which the Fund invests may differ and/or may not be as extensive or protective as those that apply in the United States.

Passive Investment Risk. The Fund is not actively managed and may be affected by a general decline in market segments related to the Underlying Index. The Fund invests in securities included in, or representative of, the Underlying Index regardless of their investment merits. BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

Privatization Risk. Some countries in which the Fund invests have begun a process of privatizing certain entities and industries. In some instances, investors in newly privatized entities have suffered losses due to the inability of the newly privatized entities to adjust quickly to a competitive environment or changing regulatory and legal standards or, in some cases, due to re-nationalization of such privatized entities. There is no assurance that such losses will not recur.

Reliance on Trading Partners Risk. The economies of the ACWI ex US telecommunication services sector countries are dependent on each other and on the United States as key trading partners. Reduction in spending on the products and services of the ACWI ex US telecommunication services sector countries by any of their key trading partners, institution of tariffs or other trade barriers or a slowdown in the economies of any of their key trading partners may cause an adverse impact on the economies of the ACWI ex US telecommunication services sector countries.


U.S. Trading Partners Risk. The United States is a significant, and in some cases the most significant, trading partner of or foreign investor in certain ACWI ex US telecommunication services sector countries and the economies of these countries may be particularly affected by changes in the U.S. economy. Decreasing U.S. imports, new trade regulations, changes in the U.S. dollar exchange rate or a recession in the United States may have a material adverse effect on the economies of ACWI ex US telecommunication services sector countries.

Securities Lending Risk. The Fund may engage in securities lending. Securities lending involves the risk that the Fund may lose money because the borrower of the Fund’s loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for the loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Security Risk. Some geographic areas in which the Fund invests have experienced acts of terrorism or strained international relations due to territorial disputes, historical animosities or other defense concerns. These situations may cause uncertainty in the markets of these geographic areas and may adversely affect the performance of their economies.

Structural Risk. Certain political, economic, legal and currency risks have contributed to a high degree of price volatility in the equity markets of the ACWI ex US telecommunication services sector countries and could adversely affect investments in the Fund:

Political and Social Risk. Disparities of wealth, the pace and success of democratization and ethnic, religious and racial disaffection, among other factors, have led to social unrest, violence and labor unrest in some ACWI ex US telecommunication services sector countries. Unanticipated or sudden political or social developments may result in sudden and significant investment losses.

Economic Risk. Some ACWI ex US telecommunication services sector countries may experience economic instability, including instability resulting from substantial rates of inflation or significant devaluations of their currency, or economic recessions causing a negative effect on the economies and securities markets of their economies. Some of these countries may also impose restrictions on the exchange or export of currency or adverse currency exchange rates and may be characterized by a lack of available currency hedging instruments.

Expropriation and/or Nationalization Risk. Investments in certain ACWI ex US telecommunication services sector countries may be subject to loss due to expropriation or nationalization of assets and property or the imposition of restrictions on foreign investments and repatriation of capital.

Large Government Debt Risk. Chronic structural public sector deficits in some ACWI ex US telecommunication services sector countries may adversely impact investments in the Fund.

Telecommunications Sector Risk. The telecommunications sector is subject to extensive government regulation. The costs of complying with governmental regulations, delays or failure to receive required regulatory approvals, or the enactment of new adverse regulatory requirements may negatively affect the business of the telecommunications companies. Government actions around the world, specifically in the area of pre-marketing clearance of products and prices, can be arbitrary and unpredictable. Companies in the telecommunications sector may encounter distressed cash flows due to the need to commit substantial capital to meet increasing competition, particularly in formulating new products and services using new technology. Technological innovations may make the products and services of telecommunications companies obsolete.

Tracking Error Risk. Imperfect correlation between the Fund’s portfolio securities and those in the Underlying Index, rounding of prices, changes to the Underlying Index and regulatory requirements may cause tracking error, which is the divergence of the Fund’s performance from that of the Underlying Index. This risk may be heightened during times of increased market volatility or other unusual market conditions.

Tracking error also may result because the Fund incurs fees and expenses, while the Underlying Index does not. Because the Fund employs a representative sampling strategy, the Fund may experience tracking error to a greater extent than a fund that seeks to replicate an index.

Valuation Risk. Because non-U.S. exchanges may be open on days when the Fund does not price its shares, the value of the securities in the Fund’s portfolio may change on days when shareholders will not be able to purchase or sell the Fund’s shares. In addition, for purposes of calculating the Fund’s NAV, the value of assets denominated in non-U.S. currencies is converted into U.S. dollars using exchange rates deemed appropriate by BFA. This conversion may result in a difference between the prices used to calculate the Fund’s NAV and the prices used by the Underlying Index, which, in turn, could result in a difference between the Fund’s performance and the performance of the Underlying Index.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

Mid-Capitalization Companies Risk. Many of the companies in which the Fund invests are considered mid-capitalization companies. Stock prices of mid-capitalization companies may be more volatile than those of large-capitalization companies and, therefore, the Fund’s share price may be more volatile than those of funds that invest a larger percentage of their assets in stocks issued by large-capitalization companies. Stock prices of mid-capitalization companies are also more vulnerable than those of large-capitalization companies to adverse business or economic developments, and the stocks of mid-capitalization companies may be less liquid, making it difficult for the Fund to buy and sell them. In addition, mid-capitalization companies generally have less diverse product lines than large-capitalization companies and are more susceptible to adverse developments related to their products.

North American Economic Risk. The United States is Canada’s and Mexico’s largest trading and investment partner. The Canadian and Mexican economies are significantly affected by developments in the U.S. economy. Since the implementation of the North American Free Trade Agreement (“NAFTA”) in 1994 among Canada, the United States and Mexico, total merchandise trade between the three countries have increased. To further this relationship, the three NAFTA countries entered into the Security and Prosperity Partnership of North America in March 2005, which may further affect Canada’s and Mexico’s dependency on the U.S. economy. Economic events in any one North American country can have a significant economic effect on the entire North American region, and on some or all of the North American countries in which the Fund invests.

Management

Investment Adviser. As investment adviser, BFA has overall responsibility for the general management and administration of the Trust. BFA provides an investment program for the Fund and manages the investment of the Fund’s assets. In managing the Fund, BFA may draw upon the research and expertise of its asset management affiliates with respect to certain portfolio securities. In seeking to achieve the Fund’s investment objective, BFA uses teams of portfolio managers, investment strategists and other investment specialists. This team approach brings together many disciplines and leverages BFA’s extensive resources.

Pursuant to the Investment Advisory Agreement between BFA and the Trust (entered into on behalf of the Fund), BFA is responsible for substantially all expenses of the Fund, except interest expenses, taxes, brokerage expenses, future distribution fees or expenses and extraordinary expenses.

For its investment advisory services to the Fund, BFA is entitled to receive a management fee from the Fund based on a percentage of the Fund’s average daily net assets, at the annual rate of 0.48%.

BFA is located at 400 Howard Street, San Francisco, CA 94105. It is a wholly owned subsidiary of BTC, which in turn is indirectly wholly-owned by BlackRock, Inc. (“BlackRock”). As of September 30, 2011, BTC and its affiliates, including BFA and BlackRock, provided investment advisory services for assets in excess of $3.35 trillion. BFA, BTC, BlackRock Execution Services, BlackRock and their affiliates deal, trade and invest for their own accounts in the types of securities in which the Fund may also invest.

A discussion regarding the basis for the Trust’s Board of Trustees’ (the “Board”) approval of the Investment Advisory Agreement with BFA is available in the Fund’s annual report for the period ended July 31.

Portfolio Managers. Rene Casis, Diane Hsiung and Greg Savage are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager is responsible for various functions related to portfolio management, including, but not limited to, investing cash inflows, coordinating with members of his or her portfolio management team to focus on certain asset classes, implementing investment strategy, researching and reviewing investment strategy and overseeing members of his or her portfolio management team that have more limited responsibilities.

Rene Casis has been employed by BFA (formerly, Barclays Global Fund Advisors (“BGFA”)) and BTC (formerly, Barclays Global Investors, N.A. (“BGI”)) as a senior portfolio manager since 2009. From 2005 to 2009, Mr. Casis was a trader at Barclays Capital. Prior to that, Mr. Casis was a portfolio manager from 2000 to 2005 for BGFA and BGI. Mr. Casis has been a Portfolio Manager of the Fund since 2010.

Diane Hsiung has been employed by BFA and BTC as a senior portfolio manager since 2007. Prior to that, Ms. Hsiung was a portfolio manager from 2002 to 2006 for BGFA and BGI. Ms. Hsiung has been a Portfolio Manager of the Fund since inception.

Greg Savage has been employed by BFA and BTC as a senior portfolio manager since 2006. Prior to that, Mr. Savage was a portfolio manager from 2001 to 2006 for BGFA and BGI. Mr. Savage has been a Portfolio Manager of the Fund since inception.

The Fund’s SAI provides additional information about the Portfolio Managers’ compensation, other accounts managed by the Portfolio Managers and the Portfolio Managers’ ownership (if any) of shares in the Fund.

Administrator, Custodian and Transfer Agent. State Street Bank and Trust Company (“State Street”) is the administrator, custodian and transfer agent for the Fund.

Conflicts of Interest. BFA wants you to know that there are certain entities with which BFA has relationships that may give rise to conflicts of interest, or the appearance of conflicts of interest. These entities include the following: BFA’s affiliates (including BlackRock and The PNC Financial Services Group, Inc., and each of their affiliates, directors, partners, trustees, managing members, officers and employees (collectively, the “Affiliates”)) and BlackRock’s significant shareholder, Barclays Bank PLC and its affiliates, including Barclays PLC (each, an “Entity” and together, the “Entities”).

The activities of BFA, the Affiliates and the Entities in the management of, or their interest in, their own accounts and other accounts they manage, may present conflicts of interest that could disadvantage the Fund and the shareholders. BFA and its Affiliates or the Entities provide investment management services to other funds and discretionary managed accounts that may follow an investment program similar to that of the Fund. BFA, its Affiliates and the Entities are involved worldwide with a broad spectrum of financial services and asset management activities and may engage in the ordinary course of business in activities in which their interests or the interests of their clients may conflict with those of the Fund. BFA, one or more of the Affiliates or the Entities acts, or may act, as an investor, investment banker, research provider, investment manager, financier, underwriter, advisor, market maker, trader, prime broker, lender, agent or principal, and have other direct and indirect interests, in securities, currencies and other instruments in which the Fund may directly or indirectly invest. Thus, it is likely that the Fund will have multiple business relationships with and will invest in, engage in transactions with, make voting decisions with respect to, or obtain services from, entities for which BFA, an Affiliate or an Entity performs or seeks to perform investment banking or other services.

BFA or one or more Affiliates or Entities may engage in proprietary trading and advise accounts and funds that have investment objectives similar to those of the Fund and/or that engage in and compete for transactions in the same types of securities, currencies and other instruments as the Fund, including in securities issued by other open-end and closed-end investment management companies, including investment companies that are affiliated with the Fund and BFA, to the extent permitted under the Investment Company Act of 1940, as amended (the “1940 Act”). The trading activities of BFA, these Affiliates and Entities are carried out without reference to positions held directly or indirectly by the Fund and may result in BFA, an Affiliate or an Entity having positions that are adverse to those of the Fund.

No Affiliate or Entity is under any obligation to share any investment opportunity, idea or strategy with the Fund. As a result, an Affiliate or an Entity may compete with the Fund for appropriate investment opportunities. As a result of this and several other factors, the results of the Fund’s investment activities may differ from those of an Affiliate or an Entity and of other accounts managed by an Affiliate or an Entity, and it is possible that the Fund could sustain losses during periods in which one or more Affiliates or Entities and other accounts achieve profits on their trading for proprietary or other accounts. The opposite result is also possible.

The Fund may, from time to time, enter into transactions in which BFA or an Affiliate’s or an Entity’s clients have an interest adverse to the Fund. Furthermore, transactions undertaken by Affiliate-advised clients may adversely impact the Fund. Transactions by one or more Affiliate- or Entity-advised clients or BFA may have the effect of diluting or otherwise disadvantaging the values, prices or investment strategies of the Fund.

An Entity may maintain securities indices as part of the product offerings. Index-based funds seek to track the performance of securities indices and may use the name of the index in the fund name. Index providers, including the Entities, may be paid licensing fees for use of their indices or index names. Entities will not be obligated to license their indices to BFA and its Affiliates, and BFA and its Affiliates will not be assured that the terms of any index licensing agreement with the Entities will be as favorable as those terms offered to other index licensees.

The Fund’s activities may be limited because of regulatory restrictions applicable to one or more Affiliates or Entities, and/or their internal policies designed to comply with such restrictions. In addition, the Fund may invest in securities of companies with which an Affiliate or an Entity has or is trying to develop investment banking relationships or in which an Affiliate or an Entity has significant debt or equity investments. The Fund also may invest in securities of companies for which an Affiliate or an Entity provides or may some day provide research coverage. An Affiliate or an Entity may have business relationships with and purchase or distribute or sell services or products from or to distributors, consultants or others who recommend the Fund or who engage in transactions with or for the Fund, and may receive compensation for such services. The Fund may also make brokerage and other payments to Affiliates or Entities in connection with the Fund’s portfolio investment transactions.

Pursuant to a securities lending program approved by the Board, the Fund has retained an Affiliate of BFA to serve as the securities lending agent for the Fund to the extent that the Fund participates in the securities lending program. For these services, the lending agent may receive a fee from the Fund, including a fee based on the returns earned on the Fund’s investment of the cash received as collateral for any loaned securities. In addition, one or more Affiliates may be among the entities to which the Fund may lend its portfolio securities under the securities lending program.

The activities of BFA, the Affiliates or Entities may give rise to other conflicts of interest that could disadvantage the Fund and the shareholders. BFA has adopted policies and procedures designed to address these potential conflicts of interest. See the Fund’s SAI for further information.

Shareholder Information

Additional shareholder information, including how to buy and sell shares of the Fund, is available free of charge by calling toll-free: 1-800-iShares (1-800-474-2737) or visiting our website at www.iShares.com.

Buying and Selling Shares. Shares of the Fund may be acquired or redeemed directly from the Fund only in Creation Units or multiples thereof, as discussed in the Creations and Redemptions section of this Prospectus. Only an Authorized Participant (as defined in the Creations and Redemptions section) may engage in creation or redemption transactions directly with the Fund. Once created, shares of the Fund generally trade in the secondary market in amounts less than a Creation Unit.

Shares of the Fund are listed on a national securities exchange for trading during the trading day. Shares can be bought and sold throughout the trading day like shares of other publicly-traded companies. The Trust does not impose any minimum investment for shares of the Fund purchased on an exchange. The Fund’s shares trade under the trading symbol “AXTE.”

Buying or selling Fund shares on an exchange involves two types of costs that may apply to all securities transactions. When buying or selling shares of the Fund through a broker, you will likely incur a brokerage commission or other charges determined by your broker. The commission is frequently a fixed amount and may be a significant proportional cost for investors seeking to buy or sell small amounts of shares. In addition, you may incur the cost of the “spread” – that is, any difference between the bid price and the ask price. The spread varies over time for shares of the Fund based on the trading volume and market liquidity, and is generally lower if the Fund has a lot of trading volume and market liquidity, and higher if the Fund has little trading volume and market liquidity.

The Board has adopted a policy of not monitoring for frequent purchases and redemptions of Fund shares (“frequent trading”) that appear to attempt to take advantage of a potential arbitrage opportunity presented by a lag between a change in the value of the Fund’s portfolio securities after the close of the primary markets for the Fund’s portfolio securities and the reflection of that change in the Fund’s NAV (“market timing”), because the Fund generally sells and redeems its shares directly through transactions that are in-kind and/or for cash, subject to the conditions described below under Creations and Redemptions. The Board has not adopted a policy of monitoring for other frequent trading activity because shares of the Fund are listed for trading on a national securities exchange.

The national securities exchange on which the Fund’s shares are listed is open for trading Monday through Friday and is closed on weekends and the following holidays: New Year’s Day, Martin Luther King, Jr. Day, Presidents’ Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day. The Fund’s primary listing exchange is NYSE Arca.

Section 12(d)(1) of the 1940 Act restricts investments by investment companies in the securities of other investment companies. Registered investment companies are permitted to invest in the Fund beyond the limits set forth in Section 12(d)(1), subject to certain terms and conditions set forth in SEC rules or in an SEC exemptive order

issued to the Trust. In order for a registered investment company to invest in shares of the Fund beyond the limitations of Section 12(d)(1) pursuant to the exemptive relief obtained by the Trust, the registered investment company must enter into an agreement with the Trust.

Book Entry. Shares of the Fund are held in book-entry form, which means that no stock certificates are issued. The Depository Trust Company (“DTC”) or its nominee is the record owner of all outstanding shares of the Fund and is recognized as the owner of all shares for all purposes.

Investors owning shares of the Fund are beneficial owners as shown on the records of DTC or its participants. DTC serves as the securities depository for shares of the Fund. DTC participants include securities brokers and dealers, banks, trust companies, clearing corporations and other institutions that directly or indirectly maintain a custodial relationship with DTC. As a beneficial owner of shares, you are not entitled to receive physical delivery of stock certificates or to have shares registered in your name, and you are not considered a registered owner of shares. Therefore, to exercise any right as an owner of shares, you must rely upon the procedures of DTC and its participants. These procedures are the same as those that apply to any other securities that you hold in book-entry or “street name” form.

Share Prices. The trading prices of the Fund’s shares in the secondary market generally differ from the Fund’s daily NAV and are affected by market forces such as supply and demand, economic conditions and other factors. Information regarding the intraday value of shares of the Fund, also known as the “indicative optimized portfolio value” (“IOPV”), is disseminated every 15 seconds throughout the trading day by the national securities exchange on which the Fund’s shares are listed or by market data vendors or other information providers. The IOPV is based on the current market value of the securities and/or cash required to be deposited in exchange for a Creation Unit. The IOPV does not necessarily reflect the precise composition of the current portfolio of securities held by the Fund at a particular point in time or the best possible valuation of the current portfolio. Therefore, the IOPV should not be viewed as a “real-time” update of the Fund’s NAV, which is computed only once a day. The IOPV is generally determined by using both current market quotations and/or price quotations obtained from broker-dealers that may trade in the portfolio securities held by the Fund. The quotations of certain Fund holdings may not be updated during U.S. trading hours if such holdings do not trade in the United States. The Fund is not involved in, or responsible for, the calculation or dissemination of the IOPV and makes no representation or warranty as to its accuracy.

Determination of Net Asset Value. The NAV of the Fund normally is determined once daily Monday through Friday, generally as of the regularly scheduled close of business of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m., Eastern time) on each day that the NYSE is open for trading, based on prices at the time of closing provided that (a) any Fund assets or liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers (as detailed below) and (b) U.S. fixed income assets may be valued as of the announced closing time for trading in fixed income instruments in a particular market or exchange. The NAV

of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets held by the Fund, and its liabilities, are determined pursuant to valuation policies and procedures approved by the Board. The Fund’s assets and liabilities are valued primarily on the basis of market quotations.

Equity investments are valued at market value, which is generally determined using the last reported official closing price or last trading price on the exchange or market on which the security is primarily traded at the time of valuation.

The Fund invests in foreign securities. Foreign currency exchange rates are generally determined as of 4:00 p.m., London time. Foreign securities owned by the Fund may trade on weekends or other days when the Fund does not price its shares. As a result, the Fund’s NAV may change on days when Authorized Participants will not be able to purchase or redeem Fund shares.

Generally, trading in foreign securities, U.S. government securities, money market instruments and certain fixed-income securities is substantially completed each day at various times prior to the close of business on the NYSE. The values of such securities used in computing the NAV of the Fund are determined as of such times.

When market quotations are not readily available or are believed by BFA to be unreliable, the Fund’s investments are valued at fair value. Fair value determinations are made by BFA in accordance with policies and procedures approved by the Fund’s Board. BFA may conclude that a market quotation is not readily available or is unreliable if a security or other asset or liability does not have a price source due to its lack of liquidity, if a market quotation differs significantly from recent price quotations or otherwise no longer appears to reflect fair value, where the security or other asset or liability is thinly traded, or where there is a significant event subsequent to the most recent market quotation. A “significant event” is an event that, in the judgment of BFA, is likely to cause a material change to the closing market price of the asset or liability held by the Fund. Foreign securities whose values are affected by volatility that occurs in U.S. markets on a trading day after the close of foreign securities markets may be fair valued.

Fair value represents a good faith approximation of the value of an asset or liability. The fair value of an asset or liability held by the Fund is the amount the Fund might reasonably expect to receive from the current sale of that asset or the cost to extinguish that liability in an arm’s-length transaction. Valuing the Fund’s investments using fair value pricing will result in prices that may differ from current market valuations and that may not be the price at which those investments could have been sold during the period in which the particular fair values were used. Use of fair value prices and certain current market valuations could result in a difference between the prices used to calculate the Fund’s NAV and the prices used by the Underlying Index, which, in turn, could result in a difference between the Fund’s performance and the performance of the Underlying Index.

The value of assets or liabilities denominated in non-U.S. currencies will be converted into U.S. dollars using exchange rates deemed appropriate by BFA as investment

adviser. Use of a rate different from the rate used by the Index Provider may adversely affect the Fund’s ability to track the Underlying Index.

Dividends and Distributions

General Policies. Dividends from net investment income, if any, generally are declared and paid semi-annually by the Fund. Distributions of net realized securities gains, if any, generally are declared and paid once a year, but the Trust may make distributions on a more frequent basis for the Fund. The Trust reserves the right to declare special distributions if, in its reasonable discretion, such action is necessary or advisable to preserve its status as a regulated investment company (“RIC”) or to avoid imposition of income or excise taxes on undistributed income or realized gains.

Dividends and other distributions on shares of the Fund are distributed on a pro rata basis to beneficial owners of such shares. Dividend payments are made through DTC participants and indirect participants to beneficial owners then of record with proceeds received from the Fund.

Dividend Reinvestment Service. No dividend reinvestment service is provided by the Trust. Broker-dealers may make available the DTC book-entry Dividend Reinvestment Service for use by beneficial owners of the Fund for reinvestment of their dividend distributions. Beneficial owners should contact their broker to determine the availability and costs of the service and the details of participation therein. Brokers may require beneficial owners to adhere to specific procedures and timetables. If this service is available and used, dividend distributions of both income and realized gains will be automatically reinvested in additional whole shares of the Fund purchased in the secondary market.

Taxes. As with any investment, you should consider how your investment in shares of the Fund will be taxed. The tax information in this Prospectus is provided as general information, based on current law. You should consult your own tax professional about the tax consequences of an investment in shares of the Fund.

Unless your investment in Fund shares is made through a tax-exempt entity or tax-deferred retirement account, such as an IRA, you need to be aware of the possible tax consequences when the Fund makes distributions or you sell Fund shares.

Taxes on Distributions. Distributions from the Fund’s net investment income (other than qualified dividend income), including distributions of income from securities lending and distributions out of the Fund’s net short-term capital gains, if any, are taxable to you as ordinary income. Distributions by the Fund of net long-term capital gains in excess of net short-term capital losses (capital gain dividends) are taxable to you as long-term capital gains, generally at a 15% tax rate (0% at certain income levels), regardless of how long you have held the Fund’s shares. Distributions by the Fund that qualify as qualified dividend income are taxable to you at long-term capital gain rates for taxable years beginning on or before December 31, 2012. The 15% and 0% tax rates expire for taxable years beginning after December 31, 2012. Maximum long-term capital gain income tax rates are scheduled to rise to 20% in 2013. Beginning in 2013, a 3.8% U.S. federal Medicare contribution tax will be imposed on “net investment income,” including interest, dividends, and capital gains, of U.S.

individuals with income exceeding $200,000 (or $250,000 if married and filing jointly), and of estates and trusts.

Dividends will be qualified dividend income to you if they are attributable to qualified dividend income received by the Fund. Generally, qualified dividend income includes dividend income from taxable U.S. corporations and qualified non-U.S. corporations, provided that the Fund satisfies certain holding period requirements in respect of the stock of such corporations and has not hedged its position in the stock in certain ways. Substitute dividends received by the Fund with respect to dividends paid on securities lent out will not be qualified dividend income. For this purpose, a qualified non-U.S. corporation means any non-U.S. corporation that is eligible for benefits under a comprehensive income tax treaty with the United States, which includes an exchange of information program or if the stock with respect to which the dividend was paid is readily tradable on an established United States securities market. The term excludes a corporation that is a passive foreign investment company.

Dividends received by the Fund from a real estate investment trust (“REIT”) or another RIC generally are qualified dividend income only to the extent the dividend distributions are made out of qualified dividend income received by such REIT or RIC. It is expected that dividends received by the Fund from a REIT and distributed to a shareholder generally will be taxable to the shareholder as ordinary income.

For a dividend to be treated as qualified dividend income, the dividend must be received with respect to a share of stock held without being hedged by the Fund, and with respect to a share of the Fund held without being hedged by you, for 61 days during the 121-day period beginning at the date which is 60 days before the date on which such share becomes ex-dividend with respect to such dividend or, in the case of certain preferred stock, 91 days during the 181-day period beginning 90 days before such date.

If your Fund shares are loaned out pursuant to a securities lending arrangement, you may lose the ability to use foreign tax credits passed through by the Fund or to treat Fund dividends paid while the shares are held by the borrower as qualified dividend income.

In general, your distributions are subject to U.S. federal income tax for the year when they are paid. Certain distributions paid in January, however, may be treated as paid on December 31 of the prior year.

If the Fund’s distributions exceed current and accumulated earnings and profits, all or a portion of the distributions made in the taxable year may be recharacterized as a return of capital to shareholders. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and result in a higher capital gain or lower capital loss when those shares on which the distribution was received are sold. Once a shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain, if the shareholder holds shares of the Fund as capital assets.

If you are neither a resident nor a citizen of the United States or if you are a non-U.S. entity, the Fund’s ordinary income dividends (which include distributions of net short-term capital gains) will generally be subject to a 30% U.S. withholding tax, unless a lower treaty rate applies, provided that withholding tax will generally not apply to any

gain or income realized by a non-U.S. shareholder in respect of any distributions of long-term capital gains or upon the sale or other disposition of shares of the Fund.

A 30% withholding tax will be imposed on dividends paid after December 31, 2013, and redemption proceeds paid after December 31, 2014, to (i) foreign financial institutions including non-U.S. investment funds unless they agree to collect and disclose to the Internal Revenue Service (“IRS”) information regarding their direct and indirect U.S. account holders and (ii) certain other foreign entities, unless they certify certain information regarding their direct and indirect U.S. owners. To avoid withholding, foreign financial institutions will need to enter into agreements with the IRS that state that they will provide the IRS information, including the name, address and taxpayer identification number of direct and indirect U.S. account holders, comply with due diligence procedures with respect to the identification of U.S. accounts, report to the IRS certain information with respect to U.S. accounts maintained, agree to withhold tax on certain payments made to non-compliant foreign financial institutions or to account holders who fail to provide the required information, and determine certain other information as to their account holders. Other foreign entities will need to provide the name, address, and taxpayer identification number of each substantial U.S. owner or certifications of no substantial U.S. ownership unless certain exceptions apply.

Dividends, interest and capital gains earned by the Fund with respect to non-U.S. securities may give rise to withholding and other taxes imposed by non-U.S. countries. Tax conventions between certain countries and the United States may reduce or eliminate such taxes. If more than 50% of the total assets of the Fund at the close of a year consists of non-U.S. stocks or securities, the Fund may “pass through” to you certain non-U.S. income taxes (including withholding taxes) paid by the Fund. This means that you would be considered to have received as an additional dividend your share of such non-U.S. taxes, but you may be entitled to either a corresponding tax deduction in calculating your taxable income, or, subject to certain limitations, a credit in calculating your U.S. federal income tax.

For purposes of foreign tax credits for U.S. shareholders of the Fund, foreign capital gains taxes may not produce associated foreign source income, thereby limiting a U.S. person’s ability to use such credits.

If you are a resident or a citizen of the United States, by law, back-up withholding will apply to your distributions and proceeds if you have not provided a taxpayer identification number or social security number and made other required certifications.

Taxes When Shares are Sold. Currently, any capital gain or loss realized upon a sale of Fund shares is generally treated as a long-term gain or loss if the shares have been held for more than one year. Any capital gain or loss realized upon a sale of Fund shares held for one year or less is generally treated as short-term gain or loss, except that any capital loss on the sale of shares held for six months or less is treated as long-term capital loss to the extent that capital gain dividends were paid with respect to such shares. Beginning in 2013, any such capital gains, including from sales of Fund shares or from capital gain dividends, will be included in “net investment income” for purposes of the 3.8% U.S. federal Medicare contribution tax mentioned above.

The foregoing discussion summarizes some of the consequences under current U.S. federal tax law of an investment in the Fund. It is not a substitute for personal tax advice. You may also be subject to state and local taxation on Fund distributions and sales of shares. Consult your personal tax adviser about the potential tax consequences of an investment in shares of the Fund under all applicable tax laws.

Creations and Redemptions. Prior to trading in the secondary market, shares of the Fund are “created” at NAV by market makers, large investors and institutions only in block-size Creation Units of 50,000 shares or multiples thereof. Each “creator” or “Authorized Participant” enters into an authorized participant agreement with the Fund’s distributor, SEI Investments Distribution Co. (the “Distributor”). Only an Authorized Participant may create or redeem Creation Units directly with the Fund. A creation transaction, which is subject to acceptance by the transfer agent, generally takes place when an Authorized Participant deposits into the Fund a designated portfolio of securities and a specified amount of cash approximating the holdings of the Fund in exchange for a specified number of Creation Units. To the extent practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund.

Similarly, shares can be redeemed only in Creation Units, generally for a designated portfolio of securities and a specified amount of cash held by the Fund (“Fund Securities”). Except when aggregated in Creation Units, shares are not redeemable by the Fund. The prices at which creations and redemptions occur are based on the next calculation of NAV after an order is received in a form described in the authorized participant agreement.

The Fund intends to comply with the U.S. federal securities laws in accepting securities for deposit and satisfying redemptions with redemption securities by, among other means, assuring that any securities accepted for deposit and any securities used to satisfy redemption requests will be sold in transactions that would be exempt from registration under the Securities Act of 1933, as amended (the “1933 Act”). Further, an Authorized Participant that is not a “qualified institutional buyer,” as such term is defined under Rule 144A of the 1933 Act, will not be able to receive Fund Securities that are restricted securities eligible for resale under Rule 144A.

Creations and redemptions must be made through a firm that is either a member of the Continuous Net Settlement System of the National Securities Clearing Corporation or a DTC participant and has executed an agreement with the Distributor with respect to creations and redemptions of Creation Unit aggregations. Information about the procedures regarding creation and redemption of Creation Units (including the cut-off times for receipt of creation and redemption orders) is included in the Fund’s SAI.

Because new shares may be created and issued on an ongoing basis, at any point during the life of the Fund a “distribution,” as such term is used in the 1933 Act, may be occurring. Broker-dealers and other persons are cautioned that some activities on their part may, depending on the circumstances, result in their being deemed participants in a distribution in a manner that could render them statutory underwriters and subject to the prospectus delivery and liability provisions of the 1933 Act. Any determination of whether one is an underwriter must take into account all the relevant facts and circumstances of each particular case.

Broker-dealers should also note that dealers who are not “underwriters” but are participating in a distribution (as contrasted to ordinary secondary transactions), and thus dealing with shares that are part of an “unsold allotment” within the meaning of Section 4(3)(C) of the 1933 Act, would be unable to take advantage of the prospectus delivery exemption provided by Section 4(3) of the 1933 Act. For delivery of prospectuses to exchange members, the prospectus delivery mechanism of Rule 153 under the 1933 Act is available only with respect to transactions on a national securities exchange.

Costs Associated with Creations and Redemptions. Authorized Participants are charged standard creation and redemption transaction fees to offset transfer and other transaction costs associated with the issuance and redemption of Creation Units. The standard creation and redemption transaction fees are set forth in the table below. The standard creation transaction fee is charged to the Authorized Participant on the day such Authorized Participant creates a Creation Unit, and is the same regardless of the number of Creation Units purchased by the Authorized Participant on the applicable business day. Similarly, the standard redemption transaction fee is charged to the Authorized Participant on the day such Authorized Participant redeems a Creation Unit, and is the same regardless of the number of Creation Units redeemed by the Authorized Participant on the applicable business day. Creations and redemptions for cash (when cash creations and redemptions (in whole or in part) are available or specified) are also subject to an additional charge (up to the maximum amounts shown in the table below). This charge is intended to compensate for brokerage, tax, foreign exchange, execution, market impact and other costs and expenses related to cash transactions. Investors who use the services of a broker or other financial intermediary may pay fees for such services.

The following table shows, as of September 30, 2011, the approximate value of one Creation Unit, standard fees and maximum additional charges for creations and redemptions (as described above):

Householding. Householding is an option available to certain Fund investors. Householding is a method of delivery, based on the preference of the individual investor, in which a single copy of certain shareholder documents can be delivered to investors who share the same address, even if their accounts are registered under different names. Please contact your broker-dealer if you are interested in enrolling in householding and receiving a single copy of prospectuses and other shareholder documents, or if you are currently enrolled in householding and wish to change your householding status.

Distribution

The Distributor distributes Creation Units for the Fund on an agency basis. The Distributor does not maintain a secondary market in shares of the Fund. The Distributor has no role in determining the policies of the Fund or the securities that are purchased or sold by the Fund. The Distributor’s principal address is One Freedom Valley Drive, Oaks, PA 19456.

In addition, BFA or its Affiliates make payments to broker-dealers, banks or other financial intermediaries (together, “intermediaries”) related to marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems, or their making shares of the Fund and certain other iShares funds available to their customers. Such payments, which may be significant to the intermediary, are not made by the Fund. Rather, such payments are made by BFA or its Affiliates from their own resources, which come directly or indirectly in part from fees paid by the iShares funds complex. Payments of this type are sometimes referred to as revenue-sharing payments. A financial intermediary may make decisions about which investment options it recommends or makes available, or the level of services provided, to its customers based on the revenue-sharing payments it is eligible to receive. Therefore, such payments to an intermediary create conflicts of interest between the intermediary and its customers and may cause the intermediary to recommend the Fund or other iShares funds over another investment. More information regarding these payments is contained in the Fund’s SAI. Please contact your salesperson or other investment professional for more information regarding any such payments his or her firm may receive from BFA or its Affiliates.

Financial Highlights

The financial highlights table is intended to help investors understand the Fund’s financial performance since inception. Certain information reflects financial results for a single share of the Fund. The total returns in the table represent the rate that an investor would have earned (or lost) on an investment in the Fund, assuming reinvestment of all dividends and distributions. This information has been audited by PricewaterhouseCoopers LLP, whose report is included, along with the Fund’s financial statements, in the Fund’s Annual Report (available upon request).

Supplemental Information

I. Premium/Discount Information

The table that follows presents information about the differences between the daily market price on secondary markets for shares of the Fund and the Fund’s NAV. NAV is the price at which the Fund issues and redeems shares. It is calculated in accordance with the standard formula for valuing mutual fund shares. The price used to calculate market returns (“Market Price”) of the Fund generally is determined using the midpoint between the highest bid and the lowest offer on the primary securities exchange on which shares of the Fund are listed for trading, as of the time that the Fund’s NAV is calculated. The Fund’s Market Price may be at, above or below its NAV. The NAV of the Fund will fluctuate with changes in the value of its portfolio holdings. The Market Price of the Fund will fluctuate in accordance with changes in its NAV, as well as market supply and demand.

Premiums or discounts are the differences (expressed as a percentage) between the NAV and Market Price of the Fund on a given day, generally at the time the NAV is calculated. A premium is the amount that the Fund is trading above the reported NAV, expressed as a percentage of the NAV. A discount is the amount that the Fund is trading below the reported NAV, expressed as a percentage of the NAV.

The following information shows the frequency of distributions of premiums and discounts for the Fund from October 1, 2010 through September 30, 2011.

Each line in the table shows the number of trading days in which the Fund traded within the premium/discount range indicated. The number of trading days in each premium/discount range is also shown as a percentage of the total number of trading days in the period covered by the table. All data presented here represents past performance, which cannot be used to predict future results.

Premium/Discount Range

Percentage of Total Days
Greater than 1.5% and Less than 2.0% 1 0.40%
Greater than 1.0% and Less than 1.5% 1 0.40

Less than -2.0% and Greater than -2.5% 2 0.79
Less than -2.5% and Greater than -3.0% 3 1.19
   253 100.00%

II. Total Return Information

The table that follows presents information about the total returns of the Fund and the Underlying Index as of the fiscal year ended July 31, 2011.

“Average Annual Total Returns” represent the average annual change in value of an investment over the periods indicated. “Cumulative Total Returns” represent the total change in value of an investment over the period indicated.

The Fund’s NAV is the value of one share of the Fund as calculated in accordance with the standard formula for valuing mutual fund shares. The NAV return is based on the NAV of the Fund and the market return is based on the Market Price of the Fund. Market Price is determined by using the midpoint between the highest bid and the lowest offer on the primary stock exchange on which shares of the Fund are listed for trading, as of the time that the Fund’s NAV is calculated. Since shares of the Fund did not trade in the secondary market until after the Fund’s inception, for the period from inception to the first day of secondary market trading in shares of the Fund, the NAV of the Fund is used as a proxy for the Market Price to calculate market returns. Market and NAV returns assume that dividends and capital gain distributions have been reinvested in the Fund at Market Price and NAV, respectively.

An index is a statistical composite that tracks a specified financial market or sector. Unlike the Fund, the Underlying Index does not actually hold a portfolio of securities and therefore does not incur the expenses incurred by the Fund. These expenses negatively impact the performance of the Fund. Also, market returns do not include brokerage commissions that may be payable on secondary market transactions. If brokerage commissions were included, market returns would be lower. The returns shown in the following table do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption or sale of Fund shares. The investment return and principal value of shares of the Fund will vary with changes in market conditions. Shares of the Fund may be worth more or less than their original cost when they are redeemed or sold in the market. The Fund’s past performance is no guarantee of future results.

Fund Overview

iSHARES® MSCI ACWI ex US UTILITIES SECTOR INDEX FUND

Ticker: AXUT Stock Exchange: NYSE Arca

Investment Objective

The iShares MSCI ACWI ex US Utilities Sector Index Fund (the “Fund”) seeks investment results that correspond generally to the price and yield performance, before fees and expenses, of the MSCI All Country World ex USA Utilities Index (the “Underlying Index”).

Fees and Expenses

The following table describes the fees and expenses that you will incur if you own shares of the Fund. The investment advisory agreement between iShares Trust (the “Trust”) and BlackRock Fund Advisors (“BFA”) (the “Investment Advisory Agreement”) provides that BFA will pay all operating expenses of the Fund, except interest expenses, taxes, brokerage expenses, future distribution fees or expenses, and extraordinary expenses.

You may also incur usual and customary brokerage commissions when buying or selling shares of the Fund, which are not reflected in the example that follows:

Example. This Example is intended to help you compare the cost of owning shares of the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

Portfolio Turnover. The Fund may pay transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 6% of the average value of its portfolio.

Principal Investment Strategies

The Underlying Index is a free float-adjusted market capitalization-weighted index designed to measure the combined equity market performance of the utilities sector of developed and emerging markets countries, excluding the United States. Component securities include those of diversified utilities providers, electric utilities providers, gas utilities providers, water utilities providers, independent power producers and energy trading companies. As of September 30, 2011, the Underlying Index consisted of companies in the following countries or regions: Australia, Austria, Belgium, Brazil, Canada, Chile, China, Colombia, the Czech Republic, Denmark, Egypt, Finland, France, Germany, Greece, Hong Kong, Hungary, India, Indonesia, Ireland, Israel, Italy, Japan, Malaysia, Mexico, Morocco, the Netherlands, New Zealand, Norway, Peru, the Philippines, Poland, Portugal, Russia, Singapore, South Africa, South Korea, Spain, Sweden, Switzerland, Taiwan, Thailand, Turkey and the United Kingdom (together, the “ACWI ex US utilities sector countries”). As of September 30, 2011, the Underlying Index was comprised of 101 securities.

BFA uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to “beat” the index it tracks and does not seek temporary defensive positions when markets decline or appear overvalued.

Indexing may eliminate the chance that the Fund will substantially outperform the Underlying Index but also may reduce some of the risks of active management, such as poor security selection. Indexing seeks to achieve lower costs and better after-tax performance by keeping portfolio turnover low in comparison to actively managed investment companies.

BFA uses a representative sampling indexing strategy to manage the Fund. “Representative sampling” is an indexing strategy that involves investing in a representative sample of securities that collectively has an investment profile similar to the Underlying Index. The securities selected are expected to have, in the aggregate, investment characteristics (based on factors such as market capitalization and industry weightings), fundamental characteristics (such as return variability and yield) and liquidity measures similar to those of the Underlying Index. The Fund may or may not hold all of the securities in the Underlying Index.

The Fund generally invests at least 80% of its assets in securities of the Underlying Index or in depositary receipts representing securities of the Underlying Index. The Fund may invest the remainder of its assets in securities

S-2   


Table Of Contents



not included in the Underlying Index, but which BFA believes will help the Fund track the Underlying Index and in other investments including futures contracts, options on futures contracts, options and swaps related to the Underlying Index, as well as cash and cash equivalents, including shares of money market funds advised by BFA or its affiliates.

The Fund may lend securities representing up to one-third of the value of the Fund’s total assets (including the value of the collateral received).

The Underlying Index is sponsored by an organization (the “Index Provider”) that is independent of the Fund and BFA. The Index Provider determines the composition and relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index. The Fund’s Index Provider is MSCI Inc. (“MSCI”).

Industry Concentration Policy. The Fund will concentrate its investments (i.e., hold 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. For purposes of this limitation, securities of the U.S. government (including its agencies and instrumentalities) and repurchase agreements collateralized by U.S. government securities are not considered to be issued by members of any industry.

Summary of Principal Risks

As with any investment, you could lose all or part of your investment in the Fund, and the Fund’s performance could trail that of other investments. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund’s net asset value per share (“NAV”), trading price, yield, total return and ability to meet its investment objective.

Asset Class Risk. Securities in the Underlying Index or in the Fund’s portfolio may underperform in comparison to the general securities markets or other asset classes.

Commodity Risk. The Fund invests in economies that are susceptible to fluctuations in certain commodity markets. Any negative changes in commodity markets could have an adverse impact on those economies.

Concentration Risk. To the extent that the Fund’s investments are concentrated in a particular issuer, region, country, market, industry or asset class, the Fund may be susceptible to loss due to adverse occurrences affecting that issuer, region, country, market, industry or asset class.

Currency Risk. Because the Fund’s NAV is determined in U.S. dollars, the Fund’s NAV could decline if the currency of a non-U.S. market in which the Fund invests depreciates against the U.S. dollar.

Custody Risk. Less developed markets are more likely to experience problems with the clearing and settling of trades and the holding of securities by local banks, agents and depositories.

Emerging Markets Risk. The Fund’s investments in emerging markets may be subject to a greater risk of loss than investments in more developed markets. Emerging markets may be more likely to experience inflation risk, political turmoil and rapid changes in

S-3   


Table Of Contents



economic conditions than more developed markets. Emerging markets often have less uniformity in accounting and reporting requirements, unreliable securities valuation and greater risk associated with custody of securities.

Energy Sector Risk. The value of securities issued by companies in the energy sector may decline for many reasons, including, without limitation, changes in commodity prices, government regulations, energy conservation efforts and potential civil liabilities.

Equity Securities Risk. Equity securities are subject to changes in value and their values may be more volatile than other asset classes.

Geographic Risk. A natural or other disaster could occur in a geographic region in which the Fund invests, which could affect the economy or particular business operations of companies in the specific geographic region, causing an adverse impact on the Fund’s investments in the affected region.

Issuer Risk. Fund performance depends on the performance of individual securities to which the Fund has exposure. Changes to the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA’s investment management strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares, losses from trading in secondary markets, periods of high volatility and disruption in the creation/redemption process of the Fund. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV.

Mid-Capitalization Companies Risk. The Fund may invest in the securities of mid-capitalization companies. Compared to large-capitalization companies, mid-capitalization companies may be less stable and more susceptible to adverse developments and their securities may be more volatile and less liquid.

Non-Diversification Risk. The Fund may invest a large percentage of its assets in securities issued by or representing a small number of issuers. As a result, the Fund’s performance may depend on the performance of a small number of issuers.

Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers are subject to the risks associated with investing in those non-U.S. markets, such as heightened risks of inflation or nationalization. The Fund may lose money due to political, economic and geographic events affecting a non-U.S. issuer or market. The Fund is specifically exposed to Asian Economic Risk and European Economic Risk.

Passive Investment Risk. The Fund is not actively managed and BFA does not attempt to take defensive positions under any market conditions, including declining markets.

Privatization Risk. Some countries in which the Fund invests have begun a process of privatizing certain entities and industries. Privatized entities may lose money or be re-nationalized.

Reliance on Trading Partners Risk. The Fund invests in countries whose economies are heavily dependent upon trading with key partners. Any reduction in this trading may have an adverse impact on the Fund’s investments. Through its trading partners, the Fund is particularly exposed to U.S. Trading Partner Risk.

Securities Lending Risk. The Fund may engage in securities lending. Securities lending involves the risk that the Fund may lose money because the borrower of the Fund’s loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Security Risk. Some countries and regions in which the Fund invests have experienced security concerns. Incidents involving a country’s or region’s security may cause uncertainty in these markets and may adversely affect their economies and the Fund’s investments.

Structural Risk. The countries in which the Fund invests may be subject to considerable degrees of economic, political and social instability.

Tracking Error Risk. The performance of the Fund may diverge from that of the Underlying Index. Because the Fund employs a representative sampling strategy, the Fund may experience tracking error to a greater extent than a fund that seeks to replicate an index. BFA EXPECTS THAT THE FUND MAY EXPERIENCE HIGHER TRACKING ERROR THAN IS TYPICAL FOR SIMILAR INDEX EXCHANGE-TRADED FUNDS.

Utilities Sector Risk. The utilities sector is subject to significant government regulation and review. Companies in the utilities sector may be adversely affected due to increases in fuel and operating costs, rising costs of financing capital construction and the cost of complying with regulations, among other factors.

Valuation Risk. The value of the securities in the Fund’s portfolio may change on days when shareholders will not be able to purchase or sell the Fund’s shares.

Performance Information

As of the date of the Fund’s prospectus (the “Prospectus”), the Fund has been in operation for less than one full calendar year and therefore does not report its performance information.

Management

Investment Adviser. BlackRock Fund Advisors.

Portfolio Managers. Rene Casis, Diane Hsiung and Greg Savage (the “Portfolio Managers”) are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager supervises a portfolio management team. Mr. Casis has been a Portfolio Manager of the Fund since 2010. Ms. Hsiung and Mr. Savage have been Portfolio Managers of the Fund since inception.

Purchase and Sale of Fund Shares

The Fund is an exchange-traded fund (commonly referred to as an “ETF”). Individual Fund shares may only be purchased and sold on a national securities exchange through a broker-dealer. The price of Fund shares is based on market price, and because ETF shares trade at market prices rather than NAV, shares may trade at a price greater than NAV (a premium) or less than NAV (a discount). The Fund will only issue or redeem shares that have been aggregated into blocks of 50,000 shares or multiples thereof (“Creation Units”) to authorized participants who have entered into agreements with the Fund’s distributor. The Fund generally will issue or redeem Creation Units in return for a designated portfolio of securities (and an amount of cash) that the Fund specifies each day.

Tax Information

The Fund intends to make distributions that may be taxable to you as ordinary income or capital gains, unless you are investing through a tax-deferred arrangement such as a 401(k) plan or an individual retirement account (“IRA”).

Payments to Broker-Dealers and other Financial Intermediaries

If you purchase shares of the Fund through a broker-dealer or other financial intermediary (such as a bank), BFA or other related companies may pay the intermediary for marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems or other services related to the sale or promotion of the Fund. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.

More Information About the Fund

This Prospectus contains important information about investing in the Fund. Please read this Prospectus carefully before you make any investment decisions. Additional information regarding the Fund is available at www.iShares.com.

BFA is the investment adviser to the Fund. Shares of the Fund are listed for trading on NYSE Arca, Inc. (“NYSE Arca”). The market price for a share of the Fund may be different from the Fund’s most recent NAV.

ETFs are funds that trade like other publicly-traded securities. The Fund is designed to track an index. Similar to shares of an index mutual fund, each share of the Fund represents a partial ownership in an underlying portfolio of securities intended to track a market index. Unlike shares of a mutual fund, which can be bought and redeemed from the issuing fund by all shareholders at a price based on NAV, shares of the Fund may be purchased or redeemed directly from the Fund at NAV solely by authorized participants. Also unlike shares of a mutual fund, shares of the Fund are listed on a national securities exchange and trade in the secondary market at market prices that change throughout the day.

The Fund invests in a particular segment of the securities markets and seeks to track the performance of a securities index that generally is not representative of the market as a whole. The Fund is designed to be used as part of broader asset allocation strategies. Accordingly, an investment in the Fund should not constitute a complete investment program.

An index is a theoretical financial calculation while the Fund is an actual investment portfolio. The performance of the Fund and the Underlying Index may vary due to transaction costs, non-U.S. currency valuations, asset valuations, corporate actions (such as mergers and spin-offs), timing variances and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions (such as diversification requirements) that apply to the Fund but not to the Underlying Index or to the use of representative sampling. “Tracking error” is the difference between the performance (return) of the Fund’s portfolio and that of the Underlying Index. BFA expects that, over time, the Fund’s tracking error will not exceed 5%. Because the Fund uses a representative sampling indexing strategy, it can be expected to have a larger tracking error than if it used a replication indexing strategy. “Replication” is an indexing strategy in which a fund invests in substantially all of the securities in its underlying index in approximately the same proportions as in the underlying index.

An investment in the Fund is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, BFA or any of its affiliates.

The Fund’s investment objective and the Underlying Index may be changed without shareholder approval.

A Further Discussion of Principal Risks

The Fund is subject to various risks, including the principal risks noted below, any of which may adversely affect the Fund’s NAV, trading price, yield, total return and ability to meet its investment objective. You could lose all or part of your investment in the Fund, and the Fund could underperform other investments.

Asian Economic Risk. Certain Asian economies have experienced over-extension of credit, currency devaluations and restrictions, high unemployment, high inflation, decreased exports and economic recessions. Economic events in any one Asian country may have a significant economic effect on the entire Asian region, as well as on major trading partners outside Asia, and any adverse event in the Asian markets may have a significant adverse effect on some or all of the ACWI ex US utilities sector countries.

Asset Class Risk. The securities in the Underlying Index or in the Fund’s portfolio may underperform the returns of other securities or indexes that track other countries, groups of countries, regions, industries, groups of industries, markets, asset classes or sectors. Various types of securities or indexes tend to experience cycles of outperformance and underperformance in comparison to the general securities markets.

Commodity Risk. Economies and companies whose performance is reflected in the Fund’s portfolio or Underlying Index may be adversely affected by changes or trends in commodity prices. Commodity prices may be influenced or characterized by unpredictable factors, including, where applicable, high volatility, changes in supply and demand relationships, weather, agriculture, trade, pestilence, political instability, changes in interest rates and monetary and other governmental policies, action and inaction. Securities of companies held by the Fund that are dependent on a single commodity, or are concentrated in a single commodity sector, may typically exhibit even higher volatility attributable to commodity prices.

Concentration Risk. To the extent that the Fund’s portfolio reflects the Underlying Index’s concentration in the securities of a particular issuer or issuers in a particular country, group of countries, region, market, industry, group of industries, sector or asset class, the Fund may be adversely affected by the performance of those securities, may be subject to increased price volatility and may be more susceptible to adverse economic, market, political or regulatory occurrences affecting that issuer, country, group of countries, region, market, industry, group of industries, sector or asset class.

Currency Risk. Because the Fund’s NAV is determined on the basis of the U.S. dollar, investors may lose money if the currency of a non-U.S. market in which the Fund invests depreciates against the U.S. dollar, even if the local currency value of the Fund’s holdings in that market increases.



Custody Risk. Custody risk refers to the risks inherent in the process of clearing and settling trades and the holding of securities by local banks, agents and depositories. Low trading volumes and volatile prices in less developed markets may make trades harder to complete and settle, and governments or trade groups may compel local agents to hold securities in designated depositories that are not subject to

independent evaluation. Local agents are held only to the standards of care of their local markets. In general, the less developed a country’s securities market is, the greater the likelihood of custody problems.

Emerging Markets Risk. Investments in emerging markets are subject to a greater risk of loss than investments in more developed markets. This is due to, among other things, the potential for greater market volatility, lower trading volume, inflation, political and economic instability, greater risk of a market shutdown and more governmental limitations on foreign investments than typically found in more developed markets. In addition, emerging markets often have less uniformity in accounting and reporting requirements, unreliable securities valuation and greater risks associated with custody of securities.

Energy Sector Risk. The energy sector is cyclical and highly dependent on commodities prices. The market values of companies in the energy sector are strongly affected by the levels and volatility of global energy prices, energy supply and demand, capital expenditures on exploration and production, energy conservation efforts, exchange rates and technological advances, among other factors. Companies in this sector may be subject to substantial government regulation and contractual fixed pricing, which may increase the cost of business and limit these companies’ earnings. A significant portion of their revenues depends on a relatively small number of customers, including governmental entities and utilities. As a result, governmental budget constraints may have a material adverse effect on the stock prices of companies in this industry. Energy companies may also operate in countries with less developed regulatory regimes or a history of expropriation, nationalization or other adverse policies. Energy companies also face a significant risk of civil liability from accidents resulting in injury or loss of life or property, pollution or other environmental mishaps, equipment malfunctions or mishandling of materials and a risk of loss from terrorism and natural disasters. Any such event could have serious consequences for the general population of the area affected and result in a material adverse impact on the Fund’s portfolio and the performance of the Fund. Energy companies can be significantly affected by the supply of, and demand for, specific products (e.g., oil and natural gas) and services, exploration and production spending, government regulation, world events and general economic conditions.

Equity Securities Risk. The Fund invests in equity securities, which are subject to changes in value that may be attributable to market perception of a particular issuer or to general stock market fluctuations that affect all issuers. Investments in equity securities may be more volatile than investments in other asset classes.

European Economic Risk. The Economic and Monetary Union of the European Union (the “EU”) requires member countries to comply with restrictions on inflation rates, deficits, interest rates, debt levels and fiscal and monetary controls, each of which may significantly affect every country in Europe. Decreasing imports or exports, changes in governmental or EU regulations on trade, changes in the exchange rate of the euro, the default or threat of default by an EU member country on its sovereign debt, and/or an economic recession in an EU member country may have a significant adverse effect on the economies of EU member countries and their trading partners, including some or all of the ACWI ex US utilities sector countries. The European financial markets have

recently experienced volatility and have been adversely affected by concerns about economic downturns, credit rating downgrades, rising government debt levels and possible default on or restructuring of government debt in several European countries, including Greece, Ireland, Italy, Portugal and Spain. A default or debt restructuring by any European country would adversely impact holders of that country’s debt, and sellers of credit default swaps linked to that country’s creditworthiness, which may be located in countries other than those listed in the previous sentence. These events have adversely affected the value and exchange rate of the euro and may continue to significantly affect the economies of every country in Europe, including EU member countries that do not use the euro and non-EU member countries.

Geographic Risk. Some markets in which the Fund invests are located in parts of the world that have historically been prone to natural disasters, such as earthquakes, volcanoes, droughts, floods, hurricanes and tsunamis, and are economically sensitive to environmental events. Any natural or other disaster could have a significant adverse impact on the economies of these geographic areas, causing an adverse impact on the Fund’s investments in the affected region.

Issuer Risk. The performance of the Fund depends on the performance of individual securities to which the Fund has exposure. Any issuer of these securities may perform poorly, causing the value of its securities to decline. Poor performance may be caused by poor management decisions, competitive pressures, changes in technology, expiration of patent protection, disruptions in supply, labor problems or shortages, corporate restructurings, fraudulent disclosures or other factors. Issuers may, in times of distress or at their own discretion, decide to reduce or eliminate dividends, which may also cause their stock prices to decline.

Management Risk. The Fund may not fully replicate the Underlying Index and may hold securities not included in the Underlying Index. As a result, the Fund is subject to the risk that BFA’s investment management strategy, the implementation of which is subject to a number of constraints, may not produce the intended results.

Market Risk. The Fund could lose money due to short-term market movements and over longer periods during market downturns. Securities may decline in value due to factors affecting securities markets generally or particular industries represented in the markets. The value of a security may decline due to general market conditions, economic trends or events that are not specifically related to the issuer of the security or to factors that affect a particular industry or industries. During a general downturn in the securities markets, multiple asset classes may be negatively affected.

Market Trading Risk

Absence of Active Market. Although shares of the Fund are listed for trading on one or more stock exchanges, there can be no assurance that an active trading market for such shares will develop or be maintained.

Risk of Secondary Listings. The Fund’s shares may be listed or traded on U.S. and non-U.S. stock exchanges other than the U.S. stock exchange where the Fund’s primary listing is maintained. There can be no assurance that the Fund’s shares will continue to trade on any such stock exchange or in any market or that the Fund’s shares will continue to meet the requirements for listing or trading on any exchange or in any

market. The Fund’s shares may be less actively traded in certain markets than others, and investors are subject to the execution and settlement risks and market standards of the market where they or their broker direct their trades for execution. Certain information available to investors who trade Fund shares on a U.S. stock exchange during regular U.S. market hours may not be available to investors who trade in other markets, which may result in secondary market prices in such markets being less efficient.

Secondary Market Trading Risk. Shares of the Fund may trade in the secondary market at times when the Fund does not accept orders to purchase or redeem shares. At such times, shares may trade in the secondary market with more significant premiums or discounts than might be experienced at times when the Fund accepts purchase and redemption orders.

Secondary market trading in Fund shares may be halted by a stock exchange because of market conditions or other reasons. In addition, trading in Fund shares on a stock exchange or in any market may be subject to trading halts caused by extraordinary market volatility pursuant to “circuit breaker” rules on the stock exchange or market. There can be no assurance that the requirements necessary to maintain the listing or trading of Fund shares will continue to be met or will remain unchanged.

Shares of the Fund May Trade at Prices Other Than NAV. Shares of the Fund trade on stock exchanges at prices at, above or below their most recent NAV. The NAV of the Fund is calculated at the end of each business day and fluctuates with changes in the market value of the Fund’s holdings since the most recent calculation. The trading prices of the Fund’s shares fluctuate continuously throughout trading hours based on market supply and demand rather than NAV. The trading prices of the Fund’s shares may deviate significantly from NAV during periods of market volatility. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV. However, because shares can be created and redeemed in Creation Units at NAV (unlike shares of many closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their NAVs), BFA believes that large discounts or premiums to the NAV of the Fund are not likely to be sustained over the long-term. While the creation/redemption feature is designed to make it likely that the Fund’s shares normally will trade on stock exchanges at prices close to the Fund’s next calculated NAV, exchange prices are not expected to correlate exactly with the Fund’s NAV due to timing reasons as well as market supply and demand factors. In addition, disruptions to creations and redemptions or extreme market volatility may result in trading prices for shares of the Fund that differ significantly from its NAV.

Costs of Buying or Selling Fund Shares. Buying or selling Fund shares on an exchange involves two types of costs that apply to all securities transactions. When buying or selling shares of the Fund through a broker, you will likely incur a brokerage commission or other charges imposed by brokers as determined by that broker. In addition, you may incur the cost of the “spread” – that is, the difference between what investors are willing to pay for Fund shares (the “bid” price) and the price at which they are willing to sell Fund shares (the “ask” price). Because of the costs inherent in buying or selling Fund shares, frequent trading may detract significantly from investment

results and an investment in Fund shares may not be advisable for investors who anticipate regularly making small investments.

Mid-Capitalization Companies Risk. Many of the companies in which the Fund invests are considered mid-capitalization companies. Stock prices of mid-capitalization companies may be more volatile than those of large-capitalization companies and, therefore, the Fund’s share price may be more volatile than those of funds that invest a larger percentage of their assets in stocks issued by large-capitalization companies. Stock prices of mid-capitalization companies are also more vulnerable than those of large-capitalization companies to adverse business or economic developments, and the stocks of mid-capitalization companies may be less liquid, making it difficult for the Fund to buy and sell them. In addition, mid-capitalization companies generally have less diverse product lines than large-capitalization companies and are more susceptible to adverse developments related to their products.

Non-Diversification Risk. The Fund is classified as “non-diversified.” This means that the Fund may invest a large percentage of its assets in securities issued by or representing a small number of issuers. As a result, the Fund may be more susceptible to the risks associated with these particular issuers, or to a single economic, political or regulatory occurrence affecting these issuers.

Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers are subject to all of the risks of investing in the markets where such issuers are located, including heightened risks of inflation or nationalization and market fluctuations caused by economic and political developments. As a result of investing in non-U.S. securities, the Fund may be subject to increased risk of loss caused by any of the factors listed below:

  • Lower levels of liquidity and market efficiency;
  • Greater securities price volatility;
  • Exchange rate fluctuations and exchange controls;
  • Less availability of public information about issuers;
  • Limitations on foreign ownership of securities;
  • Imposition of withholding or other taxes;
  • Imposition of restrictions on the expatriation of the funds or other assets of the Fund;
  • Higher transaction and custody costs and delays in settlement procedures;
  • Difficulties in enforcing contractual obligations;
  • Lower levels of regulation of the securities market;
  • Weaker accounting, disclosure and reporting requirements; and
  • Legal principles related to corporate governance, directors’ fiduciary duties and liabilities and stockholders’ rights in markets in which the Fund invests may differ and/or may not be as extensive or protective as those that apply in the United States.

Passive Investment Risk. The Fund is not actively managed and may be affected by a general decline in market segments related to the Underlying Index. The Fund invests

in securities included in, or representative of, the Underlying Index regardless of their investment merits. BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

Privatization Risk. Some countries in which the Fund invests have begun a process of privatizing certain entities and industries. In some instances, investors in newly privatized entities have suffered losses due to the inability of the newly privatized entities to adjust quickly to a competitive environment or changing regulatory and legal standards or, in some cases, due to re-nationalization of such privatized entities. There is no assurance that such losses will not recur.

Reliance on Trading Partners Risk. The economies of the ACWI ex US utilities sector countries are dependent on each other and on the United States as key trading partners. Reduction in spending on the products and services of the ACWI ex US utilities sector countries by any of their key trading partners, institution of tariffs or other trade barriers or a slowdown in the economies of any of their key trading partners may cause an adverse impact on the economies of the ACWI ex US utilities sector countries.


U.S. Trading Partners Risk. The United States is a significant, and in some cases the most significant, trading partner of or foreign investor in certain ACWI ex US utilities sector countries and the economies of these countries may be particularly affected by changes in the U.S. economy. Decreasing U.S. imports, new trade regulations, changes in the U.S. dollar exchange rate or a recession in the United States may have a material adverse effect on the economies of ACWI ex US utilities sector countries.

Securities Lending Risk. The Fund may engage in securities lending. Securities lending involves the risk that the Fund may lose money because the borrower of the Fund’s loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for the loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Security Risk. Some geographic areas in which the Fund invests have experienced acts of terrorism or strained international relations due to territorial disputes, historical animosities or other defense concerns. These situations may cause uncertainty in the markets of these geographic areas and may adversely affect the performance of their economies.

Structural Risk. Certain political, economic, legal and currency risks have contributed to a high degree of price volatility in the equity markets of the ACWI ex US utilities sector countries and could adversely affect investments in the Fund:

Political and Social Risk. Disparities of wealth, the pace and success of democratization and ethnic, religious and racial disaffection, among other factors, have led to social unrest, violence and labor unrest in some ACWI ex US utilities sector countries. Unanticipated or sudden political or social developments may result in sudden and significant investment losses.

Economic Risk. Some ACWI ex US utilities sector countries may experience economic instability, including instability resulting from substantial rates of inflation or significant devaluations of their currency, or economic recessions causing a negative effect on the economies and securities markets of their economies. Some of these countries may also impose restrictions on the exchange or export of currency or adverse currency exchange rates and may be characterized by a lack of available currency hedging instruments.

Expropriation and/or Nationalization Risk. Investments in certain ACWI ex US utilities sector countries may be subject to loss due to expropriation or nationalization of assets and property or the imposition of restrictions on foreign investments and repatriation of capital.

Large Government Debt Risk. Chronic structural public sector deficits in some ACWI ex US utilities sector countries may adversely impact investments in the Fund.

Tracking Error Risk. Imperfect correlation between the Fund’s portfolio securities and those in the Underlying Index, rounding of prices, changes to the Underlying Index and regulatory requirements may cause tracking error, which is the divergence of the Fund’s performance from that of the Underlying Index. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Underlying Index does not. Because the Fund employs a representative sampling strategy, the Fund may experience tracking error to a greater extent than a fund that seeks to replicate an index. BFA EXPECTS THAT THE FUND MAY EXPERIENCE HIGHER TRACKING ERROR THAN IS TYPICAL FOR SIMILAR INDEX ETFS.

Utilities Sector Risk. Companies in the utilities sector may be adversely affected by changes in exchange rates, domestic and international competition, and governmental limitation on rates charged to customers. The value of regulated utility debt securities (and, to a lesser extent, equity securities) tends to have an inverse relationship to the movement of interest rates. Deregulation is subjecting utility companies to greater competition and may adversely affect profitability. As deregulation allows utilities companies to diversify outside of their original geographic regions and their traditional lines of business, utilities companies may engage in riskier ventures. Companies in the utilities industry may have difficulty obtaining an adequate return on invested capital, raising capital, and financing large construction programs during periods of inflation or unsettled capital markets; face restrictions on operations and increased cost and delays attributable to environmental considerations and regulation; find that existing plants, equipment or products have been rendered obsolete by technical innovations; and be subject to increased costs because of the scarcity of certain fuels or the effects of man-made disasters. Existing and possible future regulations or legislation may make it difficult for utility companies to operate profitably. There is no assurance that regulatory authorities will, in the future, grant rate increases, or that such increases will be adequate to permit the payment of dividends on stocks issued by a utility company. Also, energy conservation and prolonged changes in climatic conditions may also have a significant impact on the revenues and expenses of utility companies. Government regulators monitor and control utility revenues and costs, and therefore may limit utility profits. In certain countries, regulatory authorities may also restrict

utility companies’ access to new markets, thereby diminishing these companies’ long-term prospects. The deregulation of certain utilities companies may eliminate restrictions on profits, but may also subject these companies to greater risks of loss.

Valuation Risk. Because non-U.S. exchanges may be open on days when the Fund does not price its shares, the value of the securities in the Fund’s portfolio may change on days when shareholders will not be able to purchase or sell the Fund’s shares. In addition, for purposes of calculating the Fund’s NAV, the value of assets denominated in non-U.S. currencies is converted into U.S. dollars using exchange rates deemed appropriate by BFA. This conversion may result in a difference between the prices used to calculate the Fund’s NAV and the prices used by the Underlying Index, which, in turn, could result in a difference between the Fund’s performance and the performance of the Underlying Index.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

Central and South American Economic Risk. The economies of certain ACWI ex US utilities sector countries are affected by the economies of Central and South American countries, some of which have experienced high interest rates, economic volatility, inflation, currency devaluations, government defaults and high unemployment rates. In addition, commodities (such as oil, gas and minerals) represent a significant percentage of the region’s exports and many economies in this region are particularly sensitive to fluctuations in commodity prices. Adverse economic events in one country may have a significant adverse effect on other countries in this region and on some economies of the ACWI ex US utilities sector countries.

Portfolio Holdings Information

A description of the Trust’s policies and procedures with respect to the disclosure of the Fund’s portfolio securities is available in the Fund’s Statement of Additional Information (“SAI”). The top holdings of the Fund can be found at www.iShares.com. Fund fact sheets provide information regarding the Fund’s top holdings and may be requested by calling 1-800-iShares (1-800-474-2737).

Management

Investment Adviser. As investment adviser, BFA has overall responsibility for the general management and administration of the Trust. BFA provides an investment program for the Fund and manages the investment of the Fund’s assets. In managing the Fund, BFA may draw upon the research and expertise of its asset management affiliates with respect to certain portfolio securities. In seeking to achieve the Fund’s investment objective, BFA uses teams of portfolio managers, investment strategists and other investment specialists. This team approach brings together many disciplines and leverages BFA’s extensive resources.

Pursuant to the Investment Advisory Agreement between BFA and the Trust (entered into on behalf of the Fund), BFA is responsible for substantially all expenses of the

Fund, except interest expenses, taxes, brokerage expenses, future distribution fees or expenses and extraordinary expenses.

For its investment advisory services to the Fund, BFA is entitled to receive a management fee from the Fund based on a percentage of the Fund’s average daily net assets, at the annual rate of 0.48%.

BFA is located at 400 Howard Street, San Francisco, CA 94105. It is a wholly owned subsidiary of BTC, which in turn is indirectly wholly-owned by BlackRock, Inc. (“BlackRock”). As of September 30, 2011, BTC and its affiliates, including BFA and BlackRock, provided investment advisory services for assets in excess of $3.35 trillion. BFA, BTC, BlackRock Execution Services, BlackRock and their affiliates deal, trade and invest for their own accounts in the types of securities in which the Fund may also invest.

A discussion regarding the basis for the Trust’s Board of Trustees’ (the “Board”) approval of the Investment Advisory Agreement with BFA is available in the Fund’s annual report for the period ended July 31.

Portfolio Managers. Rene Casis, Diane Hsiung and Greg Savage are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager is responsible for various functions related to portfolio management, including, but not limited to, investing cash inflows, coordinating with members of his or her portfolio management team to focus on certain asset classes, implementing investment strategy, researching and reviewing investment strategy and overseeing members of his or her portfolio management team that have more limited responsibilities.

Rene Casis has been employed by BFA (formerly, Barclays Global Fund Advisors (“BGFA”)) and BTC (formerly, Barclays Global Investors, N.A. (“BGI”)) as a senior portfolio manager since 2009. From 2005 to 2009, Mr. Casis was a trader at Barclays Capital. Prior to that, Mr. Casis was a portfolio manager from 2000 to 2005 for BGFA and BGI. Mr. Casis has been a Portfolio Manager of the Fund since 2010.

Diane Hsiung has been employed by BFA and BTC as a senior portfolio manager since 2007. Prior to that, Ms. Hsiung was a portfolio manager from 2002 to 2006 for BGFA and BGI. Ms. Hsiung has been a Portfolio Manager of the Fund since inception.

Greg Savage has been employed by BFA and BTC as a senior portfolio manager since 2006. Prior to that, Mr. Savage was a portfolio manager from 2001 to 2006 for BGFA and BGI. Mr. Savage has been a Portfolio Manager of the Fund since inception.

The Fund’s SAI provides additional information about the Portfolio Managers’ compensation, other accounts managed by the Portfolio Managers and the Portfolio Managers’ ownership (if any) of shares in the Fund.

Administrator, Custodian and Transfer Agent. State Street Bank and Trust Company (“State Street”) is the administrator, custodian and transfer agent for the Fund.

Conflicts of Interest. BFA wants you to know that there are certain entities with which BFA has relationships that may give rise to conflicts of interest, or the appearance of conflicts of interest. These entities include the following: BFA’s affiliates (including BlackRock and The PNC Financial Services Group, Inc., and each of their

affiliates, directors, partners, trustees, managing members, officers and employees (collectively, the “Affiliates”)) and BlackRock’s significant shareholder, Barclays Bank PLC and its affiliates, including Barclays PLC (each, an “Entity” and together, the “Entities”).

The activities of BFA, the Affiliates and the Entities in the management of, or their interest in, their own accounts and other accounts they manage, may present conflicts of interest that could disadvantage the Fund and the shareholders. BFA and its Affiliates or the Entities provide investment management services to other funds and discretionary managed accounts that may follow an investment program similar to that of the Fund. BFA, its Affiliates and the Entities are involved worldwide with a broad spectrum of financial services and asset management activities and may engage in the ordinary course of business in activities in which their interests or the interests of their clients may conflict with those of the Fund. BFA, one or more of the Affiliates or the Entities acts, or may act, as an investor, investment banker, research provider, investment manager, financier, underwriter, advisor, market maker, trader, prime broker, lender, agent or principal, and have other direct and indirect interests, in securities, currencies and other instruments in which the Fund may directly or indirectly invest. Thus, it is likely that the Fund will have multiple business relationships with and will invest in, engage in transactions with, make voting decisions with respect to, or obtain services from, entities for which BFA, an Affiliate or an Entity performs or seeks to perform investment banking or other services.

BFA or one or more Affiliates or Entities may engage in proprietary trading and advise accounts and funds that have investment objectives similar to those of the Fund and/or that engage in and compete for transactions in the same types of securities, currencies and other instruments as the Fund, including in securities issued by other open-end and closed-end investment management companies, including investment companies that are affiliated with the Fund and BFA, to the extent permitted under the Investment Company Act of 1940, as amended (the “1940 Act”). The trading activities of BFA, these Affiliates and Entities are carried out without reference to positions held directly or indirectly by the Fund and may result in BFA, an Affiliate or an Entity having positions that are adverse to those of the Fund.

No Affiliate or Entity is under any obligation to share any investment opportunity, idea or strategy with the Fund. As a result, an Affiliate or an Entity may compete with the Fund for appropriate investment opportunities. As a result of this and several other factors, the results of the Fund’s investment activities may differ from those of an Affiliate or an Entity and of other accounts managed by an Affiliate or an Entity, and it is possible that the Fund could sustain losses during periods in which one or more Affiliates or Entities and other accounts achieve profits on their trading for proprietary or other accounts. The opposite result is also possible.

The Fund may, from time to time, enter into transactions in which BFA or an Affiliate’s or an Entity’s clients have an interest adverse to the Fund. Furthermore, transactions undertaken by Affiliate-advised clients may adversely impact the Fund. Transactions by one or more Affiliate- or Entity-advised clients or BFA may have the effect of diluting or otherwise disadvantaging the values, prices or investment strategies of the Fund.

An Entity may maintain securities indices as part of the product offerings. Index-based funds seek to track the performance of securities indices and may use the name of the index in the fund name. Index providers, including the Entities, may be paid licensing fees for use of their indices or index names. Entities will not be obligated to license their indices to BFA and its Affiliates, and BFA and its Affiliates will not be assured that the terms of any index licensing agreement with the Entities will be as favorable as those terms offered to other index licensees.

The Fund’s activities may be limited because of regulatory restrictions applicable to one or more Affiliates or Entities, and/or their internal policies designed to comply with such restrictions. In addition, the Fund may invest in securities of companies with which an Affiliate or an Entity has or is trying to develop investment banking relationships or in which an Affiliate or an Entity has significant debt or equity investments. The Fund also may invest in securities of companies for which an Affiliate or an Entity provides or may some day provide research coverage. An Affiliate or an Entity may have business relationships with and purchase or distribute or sell services or products from or to distributors, consultants or others who recommend the Fund or who engage in transactions with or for the Fund, and may receive compensation for such services. The Fund may also make brokerage and other payments to Affiliates or Entities in connection with the Fund’s portfolio investment transactions.

Pursuant to a securities lending program approved by the Board, the Fund has retained an Affiliate of BFA to serve as the securities lending agent for the Fund to the extent that the Fund participates in the securities lending program. For these services, the lending agent may receive a fee from the Fund, including a fee based on the returns earned on the Fund’s investment of the cash received as collateral for any loaned securities. In addition, one or more Affiliates may be among the entities to which the Fund may lend its portfolio securities under the securities lending program.

The activities of BFA, the Affiliates or Entities may give rise to other conflicts of interest that could disadvantage the Fund and the shareholders. BFA has adopted policies and procedures designed to address these potential conflicts of interest. See the Fund’s SAI for further information.

Shareholder Information

Buying and Selling Shares. Shares of the Fund may be acquired or redeemed directly from the Fund only in Creation Units or multiples thereof, as discussed in the Creations and Redemptions section of this Prospectus. Only an Authorized Participant (as defined in the Creations and Redemptions section) may engage in creation or redemption transactions directly with the Fund. Once created, shares of the Fund generally trade in the secondary market in amounts less than a Creation Unit.

Shares of the Fund are listed on a national securities exchange for trading during the trading day. Shares can be bought and sold throughout the trading day like shares of other publicly-traded companies. The Trust does not impose any minimum investment

for shares of the Fund purchased on an exchange. The Fund’s shares trade under the trading symbol “AXUT.”

Buying or selling Fund shares on an exchange involves two types of costs that may apply to all securities transactions. When buying or selling shares of the Fund through a broker, you will likely incur a brokerage commission or other charges determined by your broker. The commission is frequently a fixed amount and may be a significant proportional cost for investors seeking to buy or sell small amounts of shares. In addition, you may incur the cost of the “spread” – that is, any difference between the bid price and the ask price. The spread varies over time for shares of the Fund based on the trading volume and market liquidity, and is generally lower if the Fund has a lot of trading volume and market liquidity, and higher if the Fund has little trading volume and market liquidity.

The Board has adopted a policy of not monitoring for frequent purchases and redemptions of Fund shares (“frequent trading”) that appear to attempt to take advantage of a potential arbitrage opportunity presented by a lag between a change in the value of the Fund’s portfolio securities after the close of the primary markets for the Fund’s portfolio securities and the reflection of that change in the Fund’s NAV (“market timing”), because the Fund generally sells and redeems its shares directly through transactions that are in-kind and/or for cash, subject to the conditions described below under Creations and Redemptions. The Board has not adopted a policy of monitoring for other frequent trading activity because shares of the Fund are listed for trading on a national securities exchange.

The national securities exchange on which the Fund’s shares are listed is open for trading Monday through Friday and is closed on weekends and the following holidays: New Year’s Day, Martin Luther King, Jr. Day, Presidents’ Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day. The Fund’s primary listing exchange is NYSE Arca.

Section 12(d)(1) of the 1940 Act restricts investments by investment companies in the securities of other investment companies. Registered investment companies are permitted to invest in the Fund beyond the limits set forth in Section 12(d)(1), subject to certain terms and conditions set forth in SEC rules or in an SEC exemptive order issued to the Trust. In order for a registered investment company to invest in shares of the Fund beyond the limitations of Section 12(d)(1) pursuant to the exemptive relief obtained by the Trust, the registered investment company must enter into an agreement with the Trust.

Book Entry. Shares of the Fund are held in book-entry form, which means that no stock certificates are issued. The Depository Trust Company (“DTC”) or its nominee is the record owner of all outstanding shares of the Fund and is recognized as the owner of all shares for all purposes.

Investors owning shares of the Fund are beneficial owners as shown on the records of DTC or its participants. DTC serves as the securities depository for shares of the Fund. DTC participants include securities brokers and dealers, banks, trust companies, clearing corporations and other institutions that directly or indirectly maintain a custodial relationship with DTC. As a beneficial owner of shares, you are not entitled to

receive physical delivery of stock certificates or to have shares registered in your name, and you are not considered a registered owner of shares. Therefore, to exercise any right as an owner of shares, you must rely upon the procedures of DTC and its participants. These procedures are the same as those that apply to any other securities that you hold in book-entry or “street name” form.

Share Prices. The trading prices of the Fund’s shares in the secondary market generally differ from the Fund’s daily NAV and are affected by market forces such as supply and demand, economic conditions and other factors. Information regarding the intraday value of shares of the Fund, also known as the “indicative optimized portfolio value” (“IOPV”), is disseminated every 15 seconds throughout the trading day by the national securities exchange on which the Fund’s shares are listed or by market data vendors or other information providers. The IOPV is based on the current market value of the securities and/or cash required to be deposited in exchange for a Creation Unit. The IOPV does not necessarily reflect the precise composition of the current portfolio of securities held by the Fund at a particular point in time or the best possible valuation of the current portfolio. Therefore, the IOPV should not be viewed as a “real-time” update of the Fund’s NAV, which is computed only once a day. The IOPV is generally determined by using both current market quotations and/or price quotations obtained from broker-dealers that may trade in the portfolio securities held by the Fund. The quotations of certain Fund holdings may not be updated during U.S. trading hours if such holdings do not trade in the United States. The Fund is not involved in, or responsible for, the calculation or dissemination of the IOPV and makes no representation or warranty as to its accuracy.

Determination of Net Asset Value. The NAV of the Fund normally is determined once daily Monday through Friday, generally as of the regularly scheduled close of business of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m., Eastern time) on each day that the NYSE is open for trading, based on prices at the time of closing provided that (a) any Fund assets or liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers (as detailed below) and (b) U.S. fixed income assets may be valued as of the announced closing time for trading in fixed income instruments in a particular market or exchange. The NAV of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets held by the Fund, and its liabilities, are determined pursuant to valuation policies and procedures approved by the Board. The Fund’s assets and liabilities are valued primarily on the basis of market quotations.

Equity investments are valued at market value, which is generally determined using the last reported official closing price or last trading price on the exchange or market on which the security is primarily traded at the time of valuation.

The Fund invests in foreign securities. Foreign currency exchange rates are generally determined as of 4:00 p.m., London time. Foreign securities owned by the Fund may trade on weekends or other days when the Fund does not price its shares. As a result,

the Fund’s NAV may change on days when Authorized Participants will not be able to purchase or redeem Fund shares.

Generally, trading in foreign securities, U.S. government securities, money market instruments and certain fixed-income securities is substantially completed each day at various times prior to the close of business on the NYSE. The values of such securities used in computing the NAV of the Fund are determined as of such times.

When market quotations are not readily available or are believed by BFA to be unreliable, the Fund’s investments are valued at fair value. Fair value determinations are made by BFA in accordance with policies and procedures approved by the Fund’s Board. BFA may conclude that a market quotation is not readily available or is unreliable if a security or other asset or liability does not have a price source due to its lack of liquidity, if a market quotation differs significantly from recent price quotations or otherwise no longer appears to reflect fair value, where the security or other asset or liability is thinly traded, or where there is a significant event subsequent to the most recent market quotation. A “significant event” is an event that, in the judgment of BFA, is likely to cause a material change to the closing market price of the asset or liability held by the Fund. Foreign securities whose values are affected by volatility that occurs in U.S. markets on a trading day after the close of foreign securities markets may be fair valued.

Fair value represents a good faith approximation of the value of an asset or liability. The fair value of an asset or liability held by the Fund is the amount the Fund might reasonably expect to receive from the current sale of that asset or the cost to extinguish that liability in an arm’s-length transaction. Valuing the Fund’s investments using fair value pricing will result in prices that may differ from current market valuations and that may not be the price at which those investments could have been sold during the period in which the particular fair values were used. Use of fair value prices and certain current market valuations could result in a difference between the prices used to calculate the Fund’s NAV and the prices used by the Underlying Index, which, in turn, could result in a difference between the Fund’s performance and the performance of the Underlying Index.

The value of assets or liabilities denominated in non-U.S. currencies will be converted into U.S. dollars using exchange rates deemed appropriate by BFA as investment adviser. Use of a rate different from the rate used by the Index Provider may adversely affect the Fund’s ability to track the Underlying Index.

Dividends and Distributions

General Policies. Dividends from net investment income, if any, generally are declared and paid semi-annually by the Fund. Distributions of net realized securities gains, if any, generally are declared and paid once a year, but the Trust may make distributions on a more frequent basis for the Fund. The Trust reserves the right to declare special distributions if, in its reasonable discretion, such action is necessary or advisable to preserve its status as a regulated investment company (“RIC”) or to avoid imposition of income or excise taxes on undistributed income or realized gains.

Dividends and other distributions on shares of the Fund are distributed on a pro rata basis to beneficial owners of such shares. Dividend payments are made through DTC

participants and indirect participants to beneficial owners then of record with proceeds received from the Fund.

Dividend Reinvestment Service. No dividend reinvestment service is provided by the Trust. Broker-dealers may make available the DTC book-entry Dividend Reinvestment Service for use by beneficial owners of the Fund for reinvestment of their dividend distributions. Beneficial owners should contact their broker to determine the availability and costs of the service and the details of participation therein. Brokers may require beneficial owners to adhere to specific procedures and timetables. If this service is available and used, dividend distributions of both income and realized gains will be automatically reinvested in additional whole shares of the Fund purchased in the secondary market.

Taxes. As with any investment, you should consider how your investment in shares of the Fund will be taxed. The tax information in this Prospectus is provided as general information, based on current law. You should consult your own tax professional about the tax consequences of an investment in shares of the Fund.

Unless your investment in Fund shares is made through a tax-exempt entity or tax-deferred retirement account, such as an IRA, you need to be aware of the possible tax consequences when the Fund makes distributions or you sell Fund shares.

Taxes on Distributions. Distributions from the Fund’s net investment income (other than qualified dividend income), including distributions of income from securities lending and distributions out of the Fund’s net short-term capital gains, if any, are taxable to you as ordinary income. Distributions by the Fund of net long-term capital gains in excess of net short-term capital losses (capital gain dividends) are taxable to you as long-term capital gains, generally at a 15% tax rate (0% at certain income levels), regardless of how long you have held the Fund’s shares. Distributions by the Fund that qualify as qualified dividend income are taxable to you at long-term capital gain rates for taxable years beginning on or before December 31, 2012. The 15% and 0% tax rates expire for taxable years beginning after December 31, 2012. Maximum long-term capital gain income tax rates are scheduled to rise to 20% in 2013. Beginning in 2013, a 3.8% U.S. federal Medicare contribution tax will be imposed on “net investment income,” including interest, dividends, and capital gains, of U.S. individuals with income exceeding $200,000 (or $250,000 if married and filing jointly), and of estates and trusts.

Dividends will be qualified dividend income to you if they are attributable to qualified dividend income received by the Fund. Generally, qualified dividend income includes dividend income from taxable U.S. corporations and qualified non-U.S. corporations, provided that the Fund satisfies certain holding period requirements in respect of the stock of such corporations and has not hedged its position in the stock in certain ways. Substitute dividends received by the Fund with respect to dividends paid on securities lent out will not be qualified dividend income. For this purpose, a qualified non-U.S. corporation means any non-U.S. corporation that is eligible for benefits under a comprehensive income tax treaty with the United States, which includes an exchange of information program or if the stock with respect to which the dividend was paid is readily tradable on an established United States securities market. The term excludes a corporation that is a passive foreign investment company.

Dividends received by the Fund from a real estate investment trust (“REIT”) or another RIC generally are qualified dividend income only to the extent the dividend distributions are made out of qualified dividend income received by such REIT or RIC. It is expected that dividends received by the Fund from a REIT and distributed to a shareholder generally will be taxable to the shareholder as ordinary income.

For a dividend to be treated as qualified dividend income, the dividend must be received with respect to a share of stock held without being hedged by the Fund, and with respect to a share of the Fund held without being hedged by you, for 61 days during the 121-day period beginning at the date which is 60 days before the date on which such share becomes ex-dividend with respect to such dividend or, in the case of certain preferred stock, 91 days during the 181-day period beginning 90 days before such date.

If your Fund shares are loaned out pursuant to a securities lending arrangement, you may lose the ability to use foreign tax credits passed through by the Fund or to treat Fund dividends paid while the shares are held by the borrower as qualified dividend income.

In general, your distributions are subject to U.S. federal income tax for the year when they are paid. Certain distributions paid in January, however, may be treated as paid on December 31 of the prior year.

If the Fund’s distributions exceed current and accumulated earnings and profits, all or a portion of the distributions made in the taxable year may be recharacterized as a return of capital to shareholders. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and result in a higher capital gain or lower capital loss when those shares on which the distribution was received are sold. Once a shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain, if the shareholder holds shares of the Fund as capital assets.

If you are neither a resident nor a citizen of the United States or if you are a non-U.S. entity, the Fund’s ordinary income dividends (which include distributions of net short-term capital gains) will generally be subject to a 30% U.S. withholding tax, unless a lower treaty rate applies, provided that withholding tax will generally not apply to any gain or income realized by a non-U.S. shareholder in respect of any distributions of long-term capital gains or upon the sale or other disposition of shares of the Fund.

A 30% withholding tax will be imposed on dividends paid after December 31, 2013, and redemption proceeds paid after December 31, 2014, to (i) foreign financial institutions including non-U.S. investment funds unless they agree to collect and disclose to the Internal Revenue Service (“IRS”) information regarding their direct and indirect U.S. account holders and (ii) certain other foreign entities, unless they certify certain information regarding their direct and indirect U.S. owners. To avoid withholding, foreign financial institutions will need to enter into agreements with the IRS that state that they will provide the IRS information, including the name, address and taxpayer identification number of direct and indirect U.S. account holders, comply with due diligence procedures with respect to the identification of U.S. accounts, report to the IRS certain information with respect to U.S. accounts maintained, agree to withhold tax on certain payments made to non-compliant foreign financial institutions or to

account holders who fail to provide the required information, and determine certain other information as to their account holders. Other foreign entities will need to provide the name, address, and taxpayer identification number of each substantial U.S. owner or certifications of no substantial U.S. ownership unless certain exceptions apply.

Dividends, interest and capital gains earned by the Fund with respect to non-U.S. securities may give rise to withholding and other taxes imposed by non-U.S. countries. Tax conventions between certain countries and the United States may reduce or eliminate such taxes. If more than 50% of the total assets of the Fund at the close of a year consists of non-U.S. stocks or securities, the Fund may “pass through” to you certain non-U.S. income taxes (including withholding taxes) paid by the Fund. This means that you would be considered to have received as an additional dividend your share of such non-U.S. taxes, but you may be entitled to either a corresponding tax deduction in calculating your taxable income, or, subject to certain limitations, a credit in calculating your U.S. federal income tax.

For purposes of foreign tax credits for U.S. shareholders of the Fund, foreign capital gains taxes may not produce associated foreign source income, thereby limiting a U.S. person’s ability to use such credits.

If you are a resident or a citizen of the United States, by law, back-up withholding will apply to your distributions and proceeds if you have not provided a taxpayer identification number or social security number and made other required certifications.

Taxes When Shares are Sold. Currently, any capital gain or loss realized upon a sale of Fund shares is generally treated as a long-term gain or loss if the shares have been held for more than one year. Any capital gain or loss realized upon a sale of Fund shares held for one year or less is generally treated as short-term gain or loss, except that any capital loss on the sale of shares held for six months or less is treated as long-term capital loss to the extent that capital gain dividends were paid with respect to such shares. Beginning in 2013, any such capital gains, including from sales of Fund shares or from capital gain dividends, will be included in “net investment income” for purposes of the 3.8% U.S. federal Medicare contribution tax mentioned above.

The foregoing discussion summarizes some of the consequences under current U.S. federal tax law of an investment in the Fund. It is not a substitute for personal tax advice. You may also be subject to state and local taxation on Fund distributions and sales of shares. Consult your personal tax adviser about the potential tax consequences of an investment in shares of the Fund under all applicable tax laws.

Creations and Redemptions. Prior to trading in the secondary market, shares of the Fund are “created” at NAV by market makers, large investors and institutions only in block-size Creation Units of 50,000 shares or multiples thereof. Each “creator” or “Authorized Participant” enters into an authorized participant agreement with the Fund’s distributor, SEI Investments Distribution Co. (the “Distributor”). Only an Authorized Participant may create or redeem Creation Units directly with the Fund. A creation transaction, which is subject to acceptance by the transfer agent, generally takes place when an Authorized Participant deposits into the Fund a designated portfolio of securities and a specified amount of cash approximating the holdings of

the Fund in exchange for a specified number of Creation Units. To the extent practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund.

Similarly, shares can be redeemed only in Creation Units, generally for a designated portfolio of securities and a specified amount of cash held by the Fund (“Fund Securities”). Except when aggregated in Creation Units, shares are not redeemable by the Fund. The prices at which creations and redemptions occur are based on the next calculation of NAV after an order is received in a form described in the authorized participant agreement.

The Fund intends to comply with the U.S. federal securities laws in accepting securities for deposit and satisfying redemptions with redemption securities by, among other means, assuring that any securities accepted for deposit and any securities used to satisfy redemption requests will be sold in transactions that would be exempt from registration under the Securities Act of 1933, as amended (the “1933 Act”). Further, an Authorized Participant that is not a “qualified institutional buyer,” as such term is defined under Rule 144A of the 1933 Act, will not be able to receive Fund Securities that are restricted securities eligible for resale under Rule 144A.

Creations and redemptions must be made through a firm that is either a member of the Continuous Net Settlement System of the National Securities Clearing Corporation or a DTC participant and has executed an agreement with the Distributor with respect to creations and redemptions of Creation Unit aggregations. Information about the procedures regarding creation and redemption of Creation Units (including the cut-off times for receipt of creation and redemption orders) is included in the Fund’s SAI.

Because new shares may be created and issued on an ongoing basis, at any point during the life of the Fund a “distribution,” as such term is used in the 1933 Act, may be occurring. Broker-dealers and other persons are cautioned that some activities on their part may, depending on the circumstances, result in their being deemed participants in a distribution in a manner that could render them statutory underwriters and subject to the prospectus delivery and liability provisions of the 1933 Act. Any determination of whether one is an underwriter must take into account all the relevant facts and circumstances of each particular case.

Broker-dealers should also note that dealers who are not “underwriters” but are participating in a distribution (as contrasted to ordinary secondary transactions), and thus dealing with shares that are part of an “unsold allotment” within the meaning of Section 4(3)(C) of the 1933 Act, would be unable to take advantage of the prospectus delivery exemption provided by Section 4(3) of the 1933 Act. For delivery of prospectuses to exchange members, the prospectus delivery mechanism of Rule 153 under the 1933 Act is available only with respect to transactions on a national securities exchange.

Costs Associated with Creations and Redemptions. Authorized Participants are charged standard creation and redemption transaction fees to offset transfer and other transaction costs associated with the issuance and redemption of Creation Units. The standard creation and redemption transaction fees are set forth in the table below. The standard creation transaction fee is charged to the Authorized Participant

on the day such Authorized Participant creates a Creation Unit, and is the same regardless of the number of Creation Units purchased by the Authorized Participant on the applicable business day. Similarly, the standard redemption transaction fee is charged to the Authorized Participant on the day such Authorized Participant redeems a Creation Unit, and is the same regardless of the number of Creation Units redeemed by the Authorized Participant on the applicable business day. Creations and redemptions for cash (when cash creations and redemptions (in whole or in part) are available or specified) are also subject to an additional charge (up to the maximum amounts shown in the table below). This charge is intended to compensate for brokerage, tax, foreign exchange, execution, market impact and other costs and expenses related to cash transactions. Investors who use the services of a broker or other financial intermediary may pay fees for such services.

The following table shows, as of September 30, 2011, the approximate value of one Creation Unit, standard fees and maximum additional charges for creations and redemptions (as described above):

Householding. Householding is an option available to certain Fund investors. Householding is a method of delivery, based on the preference of the individual investor, in which a single copy of certain shareholder documents can be delivered to investors who share the same address, even if their accounts are registered under different names. Please contact your broker-dealer if you are interested in enrolling in householding and receiving a single copy of prospectuses and other shareholder documents, or if you are currently enrolled in householding and wish to change your householding status.

Distribution

The Distributor distributes Creation Units for the Fund on an agency basis. The Distributor does not maintain a secondary market in shares of the Fund. The Distributor has no role in determining the policies of the Fund or the securities that are purchased or sold by the Fund. The Distributor’s principal address is One Freedom Valley Drive, Oaks, PA 19456.

In addition, BFA or its Affiliates make payments to broker-dealers, banks or other financial intermediaries (together, “intermediaries”) related to marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems, or their making shares of the Fund and certain other iShares funds available to their customers. Such payments, which may be significant to the intermediary, are not made by the Fund. Rather, such payments are

made by BFA or its Affiliates from their own resources, which come directly or indirectly in part from fees paid by the iShares funds complex. Payments of this type are sometimes referred to as revenue-sharing payments. A financial intermediary may make decisions about which investment options it recommends or makes available, or the level of services provided, to its customers based on the revenue-sharing payments it is eligible to receive. Therefore, such payments to an intermediary create conflicts of interest between the intermediary and its customers and may cause the intermediary to recommend the Fund or other iShares funds over another investment. More information regarding these payments is contained in the Fund’s SAI. Please contact your salesperson or other investment professional for more information regarding any such payments his or her firm may receive from BFA or its Affiliates.

Financial Highlights

The financial highlights table is intended to help investors understand the Fund’s financial performance since inception. Certain information reflects financial results for a single share of the Fund. The total returns in the table represent the rate that an investor would have earned (or lost) on an investment in the Fund, assuming reinvestment of all dividends and distributions. This information has been audited by PricewaterhouseCoopers LLP, whose report is included, along with the Fund’s financial statements, in the Fund’s Annual Report (available upon request).

Supplemental Information

I. Premium/Discount Information

The table that follows presents information about the differences between the daily market price on secondary markets for shares of the Fund and the Fund’s NAV. NAV is the price at which the Fund issues and redeems shares. It is calculated in accordance with the standard formula for valuing mutual fund shares. The price used to calculate market returns (“Market Price”) of the Fund generally is determined using the midpoint between the highest bid and the lowest offer on the primary securities exchange on which shares of the Fund are listed for trading, as of the time that the Fund’s NAV is calculated. The Fund’s Market Price may be at, above or below its NAV. The NAV of the Fund will fluctuate with changes in the value of its portfolio holdings. The Market Price of the Fund will fluctuate in accordance with changes in its NAV, as well as market supply and demand.

Premiums or discounts are the differences (expressed as a percentage) between the NAV and Market Price of the Fund on a given day, generally at the time the NAV is calculated. A premium is the amount that the Fund is trading above the reported NAV, expressed as a percentage of the NAV. A discount is the amount that the Fund is trading below the reported NAV, expressed as a percentage of the NAV.

The following information shows the frequency of distributions of premiums and discounts for the Fund from October 1, 2010 through September 30, 2011.

Each line in the table shows the number of trading days in which the Fund traded within the premium/discount range indicated. The number of trading days in each premium/discount range is also shown as a percentage of the total number of trading days in the period covered by the table. All data presented here represents past performance, which cannot be used to predict future results.

   253 100.00%

II. Total Return Information

The table that follows presents information about the total returns of the Fund and the Underlying Index as of the fiscal year ended July 31, 2011.

“Average Annual Total Returns” represent the average annual change in value of an investment over the periods indicated. “Cumulative Total Returns” represent the total change in value of an investment over the period indicated.

The Fund’s NAV is the value of one share of the Fund as calculated in accordance with the standard formula for valuing mutual fund shares. The NAV return is based on the NAV of the Fund and the market return is based on the Market Price of the Fund. Market Price is determined by using the midpoint between the highest bid and the lowest offer on the primary stock exchange on which shares of the Fund are listed for trading, as of the time that the Fund’s NAV is calculated. Since shares of the Fund did not trade in the secondary market until after the Fund’s inception, for the period from inception to the first day of secondary market trading in shares of the Fund, the NAV of the Fund is used as a proxy for the Market Price to calculate market returns. Market and NAV returns assume that dividends and capital gain distributions have been reinvested in the Fund at Market Price and NAV, respectively.

An index is a statistical composite that tracks a specified financial market or sector. Unlike the Fund, the Underlying Index does not actually hold a portfolio of securities and therefore does not incur the expenses incurred by the Fund. These expenses negatively impact the performance of the Fund. Also, market returns do not include brokerage commissions that may be payable on secondary market transactions. If brokerage commissions were included, market returns would be lower. The returns shown in the following table do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption or sale of Fund shares. The investment return and principal value of shares of the Fund will vary with changes in market conditions. Shares of the Fund may be worth more or less than their original cost when they are redeemed or sold in the market. The Fund’s past performance is no guarantee of future results.

Fund Overview

iSHARES® MSCI ACWI INDEX FUND

Ticker: ACWI Stock Exchange: NASDAQ

Investment Objective

The iShares MSCI ACWI Index Fund (the “Fund”) seeks investment results that correspond generally to the price and yield performance, before fees and expenses, of the MSCI All Country World Index (the “Underlying Index”).

Fees and Expenses

The following table describes the fees and expenses that you will incur if you own shares of the Fund. The investment advisory agreement between iShares Trust (the “Trust”) and BlackRock Fund Advisors (“BFA”) (the “Investment Advisory Agreement”) provides that BFA will pay all operating expenses of the Fund, except interest expenses, taxes, brokerage expenses, future distribution fees or expenses, and extraordinary expenses.

You may also incur usual and customary brokerage commissions when buying or selling shares of the Fund, which are not reflected in the example that follows:

Annual Fund Operating Expenses

Fund
Operating
Expenses
0.34% None None 0.34%

Example. This Example is intended to help you compare the cost of owning shares of the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

1 Year
3 Years
5 Years
10 Years
$35 $109 $191 $431

Portfolio Turnover. The Fund may pay transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 5% of the average value of its portfolio.

Principal Investment Strategies

The Underlying Index is a free float-adjusted market capitalization index designed to measure the combined equity market performance of developed and emerging markets countries. As of September 30, 2011, the Underlying Index consisted of companies in the following countries or regions: Australia, Austria, Belgium, Brazil, Canada, Chile, China, Colombia, the Czech Republic, Denmark, Egypt, Finland, France, Germany, Greece, Hong Kong, Hungary, India, Indonesia, Ireland, Israel, Italy, Japan, Malaysia, Mexico, Morocco, the Netherlands, New Zealand, Norway, Peru, the Philippines, Poland, Portugal, Russia, Singapore, South Africa, South Korea, Spain, Sweden, Switzerland, Taiwan, Thailand, Turkey, the United Kingdom and the United States (together, the “ACWI countries”). As of September 30, 2011, the Underlying Index was comprised of 2,457 securities. Component companies include energy, financial and information technology companies.

BFA uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to “beat” the index it tracks and does not seek temporary defensive positions when markets decline or appear overvalued.

Indexing may eliminate the chance that the Fund will substantially outperform the Underlying Index but also may reduce some of the risks of active management, such as poor security selection. Indexing seeks to achieve lower costs and better after-tax performance by keeping portfolio turnover low in comparison to actively managed investment companies.

BFA uses a representative sampling indexing strategy to manage the Fund. “Representative sampling” is an indexing strategy that involves investing in a representative sample of securities that collectively has an investment profile similar to the Underlying Index. The securities selected are expected to have, in the aggregate, investment characteristics (based on factors such as market capitalization and industry weightings), fundamental characteristics (such as return variability and yield) and liquidity measures similar to those of the Underlying Index. The Fund may or may not hold all of the securities in the Underlying Index.

The Fund generally invests at least 90% of its assets in securities of the Underlying Index and in depositary receipts representing securities of the Underlying Index. The Fund may invest the remainder of its assets in securities not included in the Underlying Index, but which BFA believes will help the Fund track the Underlying Index and in other investments including futures contracts, options on futures contracts,

S-2   


Table Of Contents



options and swaps as well as cash and cash equivalents, including shares of money market funds advised by BFA or its affiliates.

The Fund may lend securities representing up to one-third of the value of the Fund’s total assets (including the value of the collateral received).

The Underlying Index is sponsored by an organization (the “Index Provider”) that is independent of the Fund and BFA. The Index Provider determines the composition and relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index. The Fund’s Index Provider is MSCI Inc. (“MSCI”).

Industry Concentration Policy. The Fund will concentrate its investments (i.e., hold 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. For purposes of this limitation, securities of the U.S. government (including its agencies and instrumentalities) and repurchase agreements collateralized by U.S. government securities are not considered to be issued by members of any industry.

Summary of Principal Risks

As with any investment, you could lose all or part of your investment in the Fund, and the Fund’s performance could trail that of other investments. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund’s net asset value per share (“NAV”), trading price, yield, total return and ability to meet its investment objective.

Asset Class Risk. Securities in the Underlying Index or in the Fund’s portfolio may underperform in comparison to the general securities markets or other asset classes.

Concentration Risk. To the extent that the Fund’s investments are concentrated in a particular issuer, region, country, market, industry or asset class, the Fund may be susceptible to loss due to adverse occurrences affecting that issuer, region, country, market, industry or asset class.

Currency Risk. Because the Fund’s NAV is determined in U.S. dollars, the Fund’s NAV could decline if the currency of a non-U.S. market in which the Fund invests depreciates against the U.S. dollar.

Custody Risk. Less developed markets are more likely to experience problems with the clearing and settling of trades and the holding of securities by local banks, agents and depositories.

Emerging Markets Risk. The Fund’s investments in emerging markets may be subject to a greater risk of loss than investments in more developed markets. Emerging markets may be more likely to experience inflation risk, political turmoil and rapid changes in economic conditions than more developed markets. Emerging markets often have less uniformity in accounting and reporting requirements, unreliable securities valuation and greater risk associated with custody of securities.

Energy Sector Risk. The value of securities issued by companies in the energy sector may decline for many reasons, including, without limitation, changes in commodity prices, government regulations, energy

S-3   


Table Of Contents



conservation efforts and potential civil liabilities.

Equity Securities Risk. Equity securities are subject to changes in value and their values may be more volatile than other asset classes.

Financial Sector Risk. Performance of companies in the financial sector may be adversely impacted by many factors, including, among others, government regulations, economic conditions, credit rating downgrades, changes in interest rates, and decreased liquidity in credit markets. This sector has experienced significant losses in the recent past, and the impact of more stringent capital requirements and of recent or future regulation on any individual financial company or on the sector as a whole cannot be predicted.

Geographic Risk. A natural or other disaster could occur in a geographic region in which the Fund invests, which could affect the economy or particular business operations of companies in the specific geographic region, causing an adverse impact on the Fund’s investments in the affected region.

Information Technology Sector Risk. Information technology companies face intense competition and potentially rapid product obsolescence. They are also heavily dependent on intellectual property rights and may be adversely affected by loss or impairment of those rights.

Issuer Risk. Fund performance depends on the performance of individual securities to which the Fund has exposure. Changes to the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA’s investment management strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares, losses from trading in secondary markets, periods of high volatility and disruption in the creation/redemption process of the Fund. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV.

Non-Diversification Risk. The Fund may invest a large percentage of its assets in securities issued by or representing a small number of issuers. As a result, the Fund’s performance may depend on the performance of a small number of issuers.

Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers are subject to the risks associated with investing in those non-U.S. markets, such as heightened risks of inflation or nationalization. The Fund may lose money due to political, economic and geographic events affecting a non-U.S. issuer or market. The Fund is specifically exposed to European Economic Risk.

Passive Investment Risk. The Fund is not actively managed and BFA does not attempt to take defensive positions under any market conditions, including declining markets.



S-4   


Table Of Contents



Privatization Risk. Some countries in which the Fund invests have begun a process of privatizing certain entities and industries. Privatized entities may lose money or be re-nationalized.

Reliance on Trading Partners Risk. The Fund invests in countries whose economies are heavily dependent upon trading with key partners. Any reduction in this trading may have an adverse impact on the Fund’s investments. Through its trading partners, the Fund is particularly exposed to U.S. Trading Partner Risk.

Securities Lending Risk. The Fund may engage in securities lending. Securities lending involves the risk that the Fund may lose money because the borrower of the Fund’s loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Security Risk. Some countries and regions in which the Fund invests have experienced security concerns. Incidents involving a country’s or region’s security may cause uncertainty in these markets and may adversely affect their economies and the Fund’s investments.

Structural Risk. The countries in which the Fund invests may be subject to considerable degrees of economic, political and social instability.

Tracking Error Risk. The performance of the Fund may diverge from that of the Underlying Index. Because the Fund employs a representative sampling strategy, the Fund may experience tracking error to a greater extent than a fund that seeks to replicate an index.

Valuation Risk. The value of the securities in the Fund’s portfolio may change on days when shareholders will not be able to purchase or sell the Fund’s shares.

1 After-tax returns in the table above are calculated using the historical highest individual U.S. federal marginal income tax rates and do not reflect the impact of state or local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown, and after-tax returns shown are not relevant to tax-exempt investors or investors who hold shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts (“IRAs”). Fund returns after taxes on distributions and sale of Fund shares are calculated assuming that an investor has sufficient capital gains of the same character from other investments to offset any capital losses from the sale of Fund shares. As a result, Fund returns after taxes on distributions and sale of Fund shares may exceed Fund returns before taxes and/or returns after taxes on distributions.

Management

Investment Adviser. BlackRock Fund Advisors.

Portfolio Managers. Rene Casis, Diane Hsiung and Greg Savage (the “Portfolio Managers”) are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager supervises a portfolio management team. Mr. Casis, Ms. Hsiung and Mr. Savage have been Portfolio Managers of the Fund since 2010, 2008 and 2008, respectively.

Purchase and Sale of Fund Shares

The Fund is an exchange-traded fund (commonly referred to as an “ETF”). Individual Fund shares may only be purchased and sold on a national securities exchange through a broker-dealer. The price of Fund shares is based on market price, and because ETF shares trade at market prices rather than NAV, shares may trade at a price greater than NAV (a premium) or less than NAV (a discount). The Fund will only issue or redeem shares that have been aggregated into blocks of 100,000 shares or multiples thereof (“Creation Units”) to authorized participants who have entered into agreements with the Fund’s distributor. The Fund generally will issue or redeem Creation Units in return for a designated portfolio of securities (and an amount of cash) that the Fund specifies each day.

Tax Information

The Fund intends to make distributions that may be taxable to you as ordinary income or capital gains, unless you are investing through a tax-deferred arrangement such as a 401(k) plan or an IRA.

Payments to Broker-Dealers and other Financial Intermediaries

If you purchase shares of the Fund through a broker-dealer or other financial intermediary (such as a bank), BFA or other related companies may pay the intermediary for marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems or other services related to the sale or promotion of the Fund. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.

More Information About the Fund

This Prospectus contains important information about investing in the Fund. Please read this Prospectus carefully before you make any investment decisions. Additional information regarding the Fund is available at www.iShares.com.

BFA is the investment adviser to the Fund. Shares of the Fund are listed for trading on The NASDAQ Stock Market (“NASDAQ”). The market price for a share of the Fund may be different from the Fund’s most recent NAV.

ETFs are funds that trade like other publicly-traded securities. The Fund is designed to track an index. Similar to shares of an index mutual fund, each share of the Fund represents a partial ownership in an underlying portfolio of securities intended to track a market index. Unlike shares of a mutual fund, which can be bought and redeemed from the issuing fund by all shareholders at a price based on NAV, shares of the Fund may be purchased or redeemed directly from the Fund at NAV solely by authorized participants. Also unlike shares of a mutual fund, shares of the Fund are listed on a national securities exchange and trade in the secondary market at market prices that change throughout the day.

The Fund invests in a particular segment of the securities markets and seeks to track the performance of a securities index that generally is not representative of the market as a whole. The Fund is designed to be used as part of broader asset allocation strategies. Accordingly, an investment in the Fund should not constitute a complete investment program.

An index is a theoretical financial calculation while the Fund is an actual investment portfolio. The performance of the Fund and the Underlying Index may vary due to transaction costs, non-U.S. currency valuations, asset valuations, corporate actions (such as mergers and spin-offs), timing variances and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions (such as diversification requirements) that apply to the Fund but not to the Underlying Index or to the use of representative sampling. “Tracking error” is the difference between the performance (return) of the Fund’s portfolio and that of the Underlying Index. BFA expects that, over time, the Fund’s tracking error will not exceed 5%. Because the Fund uses a representative sampling indexing strategy, it can be expected to have a larger tracking error than if it used a replication indexing strategy. “Replication” is an indexing strategy in which a fund invests in substantially all of the securities in its underlying index in approximately the same proportions as in the underlying index.

An investment in the Fund is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, BFA or any of its affiliates.

The Fund’s investment objective and the Underlying Index may be changed without shareholder approval.

A Further Discussion of Principal Risks

The Fund is subject to various risks, including the principal risks noted below, any of which may adversely affect the Fund’s NAV, trading price, yield, total return and ability to meet its investment objective. You could lose all or part of your investment in the Fund, and the Fund could underperform other investments.

Asset Class Risk. The securities in the Underlying Index or in the Fund’s portfolio may underperform the returns of other securities or indexes that track other countries, groups of countries, regions, industries, groups of industries, markets, asset classes or sectors. Various types of securities or indexes tend to experience cycles of outperformance and underperformance in comparison to the general securities markets.

Concentration Risk. To the extent that the Fund’s portfolio reflects the Underlying Index’s concentration in the securities of a particular issuer or issuers in a particular country, group of countries, region, market, industry, group of industries, sector or asset class, the Fund may be adversely affected by the performance of those securities, may be subject to increased price volatility and may be more susceptible to adverse economic, market, political or regulatory occurrences affecting that issuer, country, group of countries, region, market, industry, group of industries, sector or asset class.

Currency Risk. Because the Fund’s NAV is determined on the basis of the U.S. dollar, investors may lose money if the currency of a non-U.S. market in which the Fund invests depreciates against the U.S. dollar, even if the local currency value of the Fund’s holdings in that market increases.

Custody Risk. Custody risk refers to the risks inherent in the process of clearing and settling trades and the holding of securities by local banks, agents and depositories. Low trading volumes and volatile prices in less developed markets may make trades harder to complete and settle, and governments or trade groups may compel local agents to hold securities in designated depositories that are not subject to independent evaluation. Local agents are held only to the standards of care of their local markets. In general, the less developed a country’s securities market is, the greater the likelihood of custody problems.

Emerging Markets Risk. Investments in emerging markets are subject to a greater risk of loss than investments in more developed markets. This is due to, among other things, the potential for greater market volatility, lower trading volume, inflation, political and economic instability, greater risk of a market shutdown and more governmental limitations on foreign investments than typically found in more developed markets. In addition, emerging markets often have less uniformity in accounting and reporting requirements, unreliable securities valuation and greater risks associated with custody of securities.

Energy Sector Risk. The energy sector is cyclical and highly dependent on commodities prices. The market values of companies in the energy sector are strongly affected by the levels and volatility of global energy prices, energy supply and demand, capital expenditures on exploration and production, energy conservation efforts, exchange rates and technological advances, among other factors. Companies in this

sector may be subject to substantial government regulation and contractual fixed pricing, which may increase the cost of business and limit these companies’ earnings. A significant portion of their revenues depends on a relatively small number of customers, including governmental entities and utilities. As a result, governmental budget constraints may have a material adverse effect on the stock prices of companies in this industry. Energy companies may also operate in countries with less developed regulatory regimes or a history of expropriation, nationalization or other adverse policies. Energy companies also face a significant risk of civil liability from accidents resulting in injury or loss of life or property, pollution or other environmental mishaps, equipment malfunctions or mishandling of materials and a risk of loss from terrorism and natural disasters. Any such event could have serious consequences for the general population of the area affected and result in a material adverse impact on the Fund’s portfolio and the performance of the Fund. Energy companies can be significantly affected by the supply of, and demand for, specific products (e.g., oil and natural gas) and services, exploration and production spending, government regulation, world events and general economic conditions.

Equity Securities Risk. The Fund invests in equity securities, which are subject to changes in value that may be attributable to market perception of a particular issuer or to general stock market fluctuations that affect all issuers. Investments in equity securities may be more volatile than investments in other asset classes.

European Economic Risk. The Economic and Monetary Union of the European Union (the “EU”) requires member countries to comply with restrictions on inflation rates, deficits, interest rates, debt levels and fiscal and monetary controls, each of which may significantly affect every country in Europe. Decreasing imports or exports, changes in governmental or EU regulations on trade, changes in the exchange rate of the euro, the default or threat of default by an EU member country on its sovereign debt, and/or an economic recession in an EU member country may have a significant adverse effect on the economies of EU member countries and their trading partners, including some or all of the ACWI countries. The European financial markets have recently experienced volatility and have been adversely affected by concerns about economic downturns, credit rating downgrades, rising government debt levels and possible default on or restructuring of government debt in several European countries, including Greece, Ireland, Italy, Portugal and Spain. A default or debt restructuring by any European country would adversely impact holders of that country’s debt, and sellers of credit default swaps linked to that country’s creditworthiness, which may be located in countries other than those listed in the previous sentence. These events have adversely affected the value and exchange rate of the euro and may continue to significantly affect the economies of every country in Europe, including EU member countries that do not use the euro and non-EU member countries.

Financial Sector Risk. Companies in the financial sector of an economy are often subject to governmental regulation and, recently, government intervention and the potential for additional regulation, which may adversely affect the scope of their activities, the prices they can charge and the amount of capital they must maintain. Governmental regulation may change frequently and may have significant adverse consequences for companies in the financial sector, including effects not intended by

such regulation. The impact of recent or future regulation in various countries on any individual financial company or on the sector as a whole cannot be predicted. Certain risks may impact the value of investments in the financial sector more severely than investments outside this sector, including the risks associated with companies that operate with substantial financial leverage. Companies in the financial sector may also be adversely affected by increases in interest rates and loan losses, decreases in the availability of money or asset valuations, credit rating downgrades and adverse conditions in other related markets. Over the past few years, the deterioration of the credit markets has impacted a broad range of mortgage, asset-backed, auction rate, sovereign debt and other markets, including U.S. and non-U.S. credit and interbank money markets, thereby affecting a wide range of financial institutions and markets. This situation has created instability in the financial markets and caused certain financial companies to incur large losses. Some financial companies have experienced declines in the valuations of their assets, taken actions to raise capital (such as the issuance of debt or equity securities), or even ceased operations. Some financial companies have borrowed significant amounts of capital from governments and may face future government-imposed restrictions on their businesses or increased government intervention. These actions have caused the securities of many financial companies to decline in value. Insurance companies, in particular, may be subject to severe price competition, which may have an adverse impact on their profitability.

Geographic Risk. Some markets in which the Fund invests are located in parts of the world that have historically been prone to natural disasters, such as earthquakes, volcanoes, droughts, floods, hurricanes and tsunamis, and are economically sensitive to environmental events. Any natural or other disaster could have a significant adverse impact on the economies of these geographic areas, causing an adverse impact on the Fund’s investments in the affected region.

Information Technology Sector Risk. Information technology companies face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Like other technology companies, information technology companies may have limited product lines, markets, financial resources or personnel. The products of information technology companies may face obsolescence due to rapid technological developments and frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Companies in the information technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies.

Issuer Risk. The performance of the Fund depends on the performance of individual securities to which the Fund has exposure. Any issuer of these securities may perform poorly, causing the value of its securities to decline. Poor performance may be caused by poor management decisions, competitive pressures, changes in technology, expiration of patent protection, disruptions in supply, labor problems or shortages, corporate restructurings, fraudulent disclosures or other factors. Issuers may, in times of distress or at their own discretion, decide to reduce or eliminate dividends, which may also cause their stock prices to decline.

Management Risk. The Fund may not fully replicate the Underlying Index and may hold securities not included in the Underlying Index. As a result, the Fund is subject to the risk that BFA’s investment management strategy, the implementation of which is subject to a number of constraints, may not produce the intended results.

Market Risk. The Fund could lose money due to short-term market movements and over longer periods during market downturns. Securities may decline in value due to factors affecting securities markets generally or particular industries represented in the markets. The value of a security may decline due to general market conditions, economic trends or events that are not specifically related to the issuer of the security or to factors that affect a particular industry or industries. During a general downturn in the securities markets, multiple asset classes may be negatively affected.

Market Trading Risk

Absence of Active Market. Although shares of the Fund are listed for trading on one or more stock exchanges, there can be no assurance that an active trading market for such shares will develop or be maintained.

Risk of Secondary Listings. The Fund’s shares may be listed or traded on U.S. and non-U.S. stock exchanges other than the U.S. stock exchange where the Fund’s primary listing is maintained. There can be no assurance that the Fund’s shares will continue to trade on any such stock exchange or in any market or that the Fund’s shares will continue to meet the requirements for listing or trading on any exchange or in any market. The Fund’s shares may be less actively traded in certain markets than others, and investors are subject to the execution and settlement risks and market standards of the market where they or their broker direct their trades for execution. Certain information available to investors who trade Fund shares on a U.S. stock exchange during regular U.S. market hours may not be available to investors who trade in other markets, which may result in secondary market prices in such markets being less efficient.

Secondary Market Trading Risk. Shares of the Fund may trade in the secondary market at times when the Fund does not accept orders to purchase or redeem shares. At such times, shares may trade in the secondary market with more significant premiums or discounts than might be experienced at times when the Fund accepts purchase and redemption orders.

Secondary market trading in Fund shares may be halted by a stock exchange because of market conditions or other reasons. In addition, trading in Fund shares on a stock exchange or in any market may be subject to trading halts caused by extraordinary market volatility pursuant to “circuit breaker” rules on the stock exchange or market. There can be no assurance that the requirements necessary to maintain the listing or trading of Fund shares will continue to be met or will remain unchanged.

Shares of the Fund May Trade at Prices Other Than NAV. Shares of the Fund trade on stock exchanges at prices at, above or below their most recent NAV. The NAV of the Fund is calculated at the end of each business day and fluctuates with changes in the market value of the Fund’s holdings since the most recent calculation. The trading prices of the Fund’s shares fluctuate continuously throughout trading hours based on market supply and demand rather than NAV. The trading prices of the Fund’s shares

may deviate significantly from NAV during periods of market volatility. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV. However, because shares can be created and redeemed in Creation Units at NAV (unlike shares of many closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their NAVs), BFA believes that large discounts or premiums to the NAV of the Fund are not likely to be sustained over the long-term. While the creation/redemption feature is designed to make it likely that the Fund’s shares normally will trade on stock exchanges at prices close to the Fund’s next calculated NAV, exchange prices are not expected to correlate exactly with the Fund’s NAV due to timing reasons as well as market supply and demand factors. In addition, disruptions to creations and redemptions or extreme market volatility may result in trading prices for shares of the Fund that differ significantly from its NAV.

Costs of Buying or Selling Fund Shares. Buying or selling Fund shares on an exchange involves two types of costs that apply to all securities transactions. When buying or selling shares of the Fund through a broker, you will likely incur a brokerage commission or other charges imposed by brokers as determined by that broker. In addition, you may incur the cost of the “spread” – that is, the difference between what investors are willing to pay for Fund shares (the “bid” price) and the price at which they are willing to sell Fund shares (the “ask” price). Because of the costs inherent in buying or selling Fund shares, frequent trading may detract significantly from investment results and an investment in Fund shares may not be advisable for investors who anticipate regularly making small investments.

Non-Diversification Risk. The Fund is classified as “non-diversified.” This means that the Fund may invest a large percentage of its assets in securities issued by or representing a small number of issuers. As a result, the Fund may be more susceptible to the risks associated with these particular issuers, or to a single economic, political or regulatory occurrence affecting these issuers.

Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers are subject to all of the risks of investing in the markets where such issuers are located, including heightened risks of inflation or nationalization and market fluctuations caused by economic and political developments. As a result of investing in non-U.S. securities, the Fund may be subject to increased risk of loss caused by any of the factors listed below:

  • Lower levels of liquidity and market efficiency;
  • Greater securities price volatility;
  • Exchange rate fluctuations and exchange controls;
  • Less availability of public information about issuers;
  • Limitations on foreign ownership of securities;
  • Imposition of withholding or other taxes;
  • Imposition of restrictions on the expatriation of the funds or other assets of the Fund;
  • Higher transaction and custody costs and delays in settlement procedures;
  • Difficulties in enforcing contractual obligations;
  • Lower levels of regulation of the securities market;
  • Weaker accounting, disclosure and reporting requirements; and
  • Legal principles related to corporate governance, directors’ fiduciary duties and liabilities and stockholders’ rights in markets in which the Fund invests may differ and/or may not be as extensive or protective as those that apply in the United States.

Passive Investment Risk. The Fund is not actively managed and may be affected by a general decline in market segments related to the Underlying Index. The Fund invests in securities included in, or representative of, the Underlying Index regardless of their investment merits. BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

Privatization Risk. Some countries in which the Fund invests have begun a process of privatizing certain entities and industries. In some instances, investors in newly privatized entities have suffered losses due to the inability of the newly privatized entities to adjust quickly to a competitive environment or changing regulatory and legal standards or, in some cases, due to re-nationalization of such privatized entities. There is no assurance that such losses will not recur.

Reliance on Trading Partners Risk. The economies of some ACWI countries are dependent on trade with certain key trading partners. Reduction in spending on the products and services of the ACWI countries, institution of tariffs or other trade barriers by any of their key trading partners or a slowdown in the economies of any of their key trading partners may cause an adverse impact on the economies of the ACWI countries.


U.S. Trading Partners Risk. The United States is a significant, and in some cases the most significant, trading partner of or foreign investor in certain ACWI countries and the economies of these countries may be particularly affected by changes in the U.S. economy. Decreasing U.S. imports, new trade regulations, changes in the U.S. dollar exchange rate or a recession in the United States may have a material adverse effect on economies of ACWI countries.

Securities Lending Risk. The Fund may engage in securities lending. Securities lending involves the risk that the Fund may lose money because the borrower of the Fund’s loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for the loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Security Risk. Some geographic areas in which the Fund invests have experienced acts of terrorism or strained international relations due to territorial disputes, historical animosities or other defense concerns. These situations may cause uncertainty in the markets of these geographic areas and may adversely affect the performance of their economies.

Structural Risks. Certain political, economic, legal and currency risks have contributed to a high degree of price volatility in the equity markets of these countries and could adversely affect investments in the Fund:

Political and Social Risk. Disparities of wealth, the pace and success of democratization and ethnic, religious and racial disaffection, among other factors, have led to social unrest, violence and labor unrest in some ACWI countries. Unanticipated or sudden political or social developments may result in sudden and significant investment losses.

Economic Risk. Some ACWI countries may experience economic instability, including instability resulting from substantial rates of inflation or significant devaluations of their currency, or economic recessions causing a negative effect on the economies and securities markets of their economies. Some of these countries may also impose restrictions on the exchange or export of currency or adverse currency exchange rates and may be characterized by a lack of available currency hedging instruments.

Expropriation Risk. Investments in certain ACWI countries may be subject to loss due to expropriation or nationalization of assets and property or the imposition of restrictions on foreign investments and repatriation of capital.

Large Government Debt Risk. Chronic structural public sector deficits in some ACWI countries may adversely impact securities held by the Fund.


Tracking Error Risk. Imperfect correlation between the Fund’s portfolio securities and those in the Underlying Index, rounding of prices, changes to the Underlying Index and regulatory requirements may cause tracking error, which is the divergence of the Fund’s performance from that of the Underlying Index. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Underlying Index does not. Because the Fund employs a representative sampling strategy, the Fund may experience tracking error to a greater extent than a fund that seeks to replicate an index.

Valuation Risk. Because non-U.S. exchanges may be open on days when the Fund does not price its shares, the value of the securities in the Fund’s portfolio may change on days when shareholders will not be able to purchase or sell the Fund’s shares. In addition, for purposes of calculating the Fund’s NAV, the value of assets denominated in non-U.S. currencies is converted into U.S. dollars using exchange rates deemed appropriate by BFA. This conversion may result in a difference between the prices used to calculate the Fund’s NAV and the prices used by the Underlying Index, which, in turn, could result in a difference between the Fund’s performance and the performance of the Underlying Index.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

Asian Economic Risk. Certain Asian economies have experienced over-extension of credit, currency devaluations and restrictions, high unemployment, high inflation, decreased exports and economic recessions. Economic events in any one Asian

country may have a significant economic effect on the entire Asian region, as well as on major trading partners outside Asia, and any adverse event in the Asian markets may have a significant adverse effect on some or all of the ACWI countries.

Consumer Discretionary Sector Risk. The success of consumer product manufacturers and retailers is tied closely to the performance of domestic and international economies, interest rates, exchange rates, competition, consumer confidence, changes in demographics and consumer preferences. Companies in the consumer discretionary sector depend heavily on disposable household income and consumer spending, and may be strongly affected by social trends and marketing campaigns. These companies may be subject to severe competition, which may have an adverse impact on their profitability.

Consumer Staples Sector Risk. The Fund invests in companies in the consumer staples sector. The consumer staples sector may be affected by the permissibility of using various food additives and production methods, marketing campaigns and other factors affecting consumer demand. Tobacco companies, in particular, may be adversely affected by new laws, regulations and litigation. The consumer staples sector may also be adversely affected by changes or trends in commodity prices, which may be influenced or characterized by unpredictable factors.

Health Care Sector Risk. The profitability of companies in the health care sector may be affected by extensive government regulations, restrictions on government reimbursement for medical expenses, rising costs of medical products and services, pricing pressure, an increased emphasis on outpatient services, limited number of products, industry innovation, changes in technologies and other market developments. Many health care companies are heavily dependent on patent protection. The expiration of patents may adversely affect the profitability of these companies. Many health care companies are subject to extensive litigation based on product liability and similar claims. Health care companies are subject to competitive forces that may make it difficult to raise prices and, in fact, may result in price discounting. Many new products in the health care sector may be subject to regulatory approvals. The process of obtaining such approvals may be long and costly. Companies in the health care sector may be thinly capitalized and may be susceptible to product obsolescence.

Industrials Sector Risk. The stock prices of companies in the industrials sector are affected by supply and demand, both for their specific product or service and for industrials sector products in general. The products of manufacturing companies may face obsolescence due to rapid technological developments and frequent new product introduction. Government regulations, world events, economic conditions and exchange rates affect the performance of companies in the industrials sector. Companies in the industrials sector may be adversely affected by liability for environmental damage, product liability claims and exchange rates. The industrials sector may also be adversely affected by changes or trends in commodity prices, which may be influenced by unpredictable factors.

Materials Sector Risk. Companies in the materials sector could be adversely affected by commodity price volatility, exchange rates, import controls, increased competition, depletion of resources, technical progress, labor relations, exchange rates and

government regulations, among other factors. Also, companies in the materials sector are at risk of liability for environmental damage and product liability claims. Production of materials may exceed demand as a result of market imbalances or economic downturns, leading to poor investment returns.

North American Economic Risk. The United States is Canada’s and Mexico’s largest trading and investment partner. The Canadian and Mexican economies are significantly affected by developments in the U.S. economy. Since the implementation of the North American Free Trade Agreement (“NAFTA”) in 1994 among Canada, the United States and Mexico, total merchandise trade between the three countries have increased. To further this relationship, the three NAFTA countries entered into the Security and Prosperity Partnership of North America in March 2005, which may further affect Canada’s and Mexico’s dependency on the U.S. economy. Economic events in any one North American country can have a significant economic effect on the entire North American region, and on some or all of the North American countries in which the Fund invests.

Telecommunications Sector Risk. The telecommunications sector is subject to extensive government regulation. The costs of complying with governmental regulations, delays or failure to receive required regulatory approvals, or the enactment of new adverse regulatory requirements may negatively affect the business of the telecommunications companies. Government actions around the world, specifically in the area of pre-marketing clearance of products and prices, can be arbitrary and unpredictable. Companies in the telecommunications sector may encounter distressed cash flows due to the need to commit substantial capital to meet increasing competition, particularly in formulating new products and services using new technology. Technological innovations may make the products and services of telecommunications companies obsolete.

Portfolio Holdings Information

A description of the Trust’s policies and procedures with respect to the disclosure of the Fund’s portfolio securities is available in the Fund’s Statement of Additional Information (“SAI”). The top holdings of the Fund can be found at www.iShares.com. Fund fact sheets provide information regarding the Fund’s top holdings and may be requested by calling 1-800-iShares (1-800-474-2737).

Management

Investment Adviser. As investment adviser, BFA has overall responsibility for the general management and administration of the Trust. BFA provides an investment program for the Fund and manages the investment of the Fund’s assets. In managing the Fund, BFA may draw upon the research and expertise of its asset management affiliates with respect to certain portfolio securities. In seeking to achieve the Fund’s investment objective, BFA uses teams of portfolio managers, investment strategists and other investment specialists. This team approach brings together many disciplines and leverages BFA’s extensive resources.

Pursuant to the Investment Advisory Agreement between BFA and the Trust (entered into on behalf of the Fund), BFA is responsible for substantially all expenses of the

Fund, except interest expenses, taxes, brokerage expenses, future distribution fees or expenses and extraordinary expenses.

For its investment advisory services to the Fund, BFA is entitled to receive a management fee from the Fund corresponding to the Fund’s allocable portion of an aggregate management fee based on the aggregate average daily net assets of the following iShares funds: iShares MSCI ACWI ex US Index Fund, iShares MSCI ACWI Index Fund, iShares MSCI All Country World Minimum Volatility Index Fund, iShares MSCI EAFE Index Fund and iShares MSCI EAFE Minimum Volatility Index Fund. The aggregate management fee is calculated as follows: 0.35% per annum of the aggregate net assets less than or equal to $30.0 billion, plus 0.32% per annum of the aggregate net assets over $30.0 billion up to and including $60.0 billion, plus 0.28% per annum of the aggregate net assets in excess of $60.0 billion. As calculated on July 31, 2011, for its investment advisory services to the Fund, BFA is entitled to receive a management fee from the Fund, based on a percentage of the Fund’s average daily net assets, at an annual rate of 0.34%.

BFA is located at 400 Howard Street, San Francisco, CA 94105. It is a wholly owned subsidiary of BTC, which in turn is indirectly wholly-owned by BlackRock, Inc. (“BlackRock”). As of September 30, 2011, BTC and its affiliates, including BFA and BlackRock, provided investment advisory services for assets in excess of $3.35 trillion. BFA, BTC, BlackRock Execution Services, BlackRock and their affiliates deal, trade and invest for their own accounts in the types of securities in which the Fund may also invest.

A discussion regarding the basis for the Trust’s Board of Trustees’ (the “Board”) approval of the Investment Advisory Agreement with BFA is available in the Fund’s annual report for the period ended July 31.

Portfolio Managers. Rene Casis, Diane Hsiung and Greg Savage are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager is responsible for various functions related to portfolio management, including, but not limited to, investing cash inflows, coordinating with members of his or her portfolio management team to focus on certain asset classes, implementing investment strategy, researching and reviewing investment strategy and overseeing members of his or her portfolio management team that have more limited responsibilities.

Rene Casis has been employed by BFA (formerly, Barclays Global Fund Advisors (“BGFA”)) and BTC (formerly, Barclays Global Investors, N.A. (“BGI”)) as a senior portfolio manager since 2009. From 2005 to 2009, Mr. Casis was a trader at Barclays Capital. Prior to that, Mr. Casis was a portfolio manager from 2000 to 2005 for BGFA and BGI. Mr. Casis has been a Portfolio Manager of the Fund since 2010.

Diane Hsiung has been employed by BFA and BTC as a senior portfolio manager since 2007. Prior to that, Ms. Hsiung was a portfolio manager from 2002 to 2006 for BGFA and BGI. Ms. Hsiung has been a Portfolio Manager of the Fund since 2008.

Greg Savage has been employed by BFA and BTC as a senior portfolio manager since 2006. Prior to that, Mr. Savage was a portfolio manager from 2001 to 2006 for BGFA and BGI. Mr. Savage has been a Portfolio Manager of the Fund since 2008.

The Fund’s SAI provides additional information about the Portfolio Managers’ compensation, other accounts managed by the Portfolio Managers and the Portfolio Managers’ ownership (if any) of shares in the Fund.

Administrator, Custodian and Transfer Agent. State Street Bank and Trust Company (“State Street”) is the administrator, custodian and transfer agent for the Fund.

Conflicts of Interest. BFA wants you to know that there are certain entities with which BFA has relationships that may give rise to conflicts of interest, or the appearance of conflicts of interest. These entities include the following: BFA’s affiliates (including BlackRock and The PNC Financial Services Group, Inc., and each of their affiliates, directors, partners, trustees, managing members, officers and employees (collectively, the “Affiliates”)) and BlackRock’s significant shareholder, Barclays Bank PLC and its affiliates, including Barclays PLC (each, an “Entity” and together, the “Entities”).

The activities of BFA, the Affiliates and the Entities in the management of, or their interest in, their own accounts and other accounts they manage, may present conflicts of interest that could disadvantage the Fund and its shareholders. BFA and its Affiliates or the Entities provide investment management services to other funds and discretionary managed accounts that may follow an investment program similar to that of the Fund. BFA, its Affiliates and the Entities are involved worldwide with a broad spectrum of financial services and asset management activities and may engage in the ordinary course of business in activities in which their interests or the interests of their clients may conflict with those of the Fund. BFA, one or more of the Affiliates or the Entities acts, or may act, as an investor, investment banker, research provider, investment manager, financier, underwriter, advisor, market maker, trader, prime broker, lender, agent or principal, and have other direct and indirect interests, in securities, currencies and other instruments in which the Fund may directly or indirectly invest. Thus, it is likely that the Fund will have multiple business relationships with and will invest in, engage in transactions with, make voting decisions with respect to, or obtain services from, entities for which BFA, an Affiliate or an Entity performs or seeks to perform investment banking or other services.

BFA or one or more Affiliates or Entities may engage in proprietary trading and advise accounts and funds that have investment objectives similar to those of the Fund and/or that engage in and compete for transactions in the same types of securities, currencies and other instruments as the Fund, including in securities issued by other open-end and closed-end investment management companies, including investment companies that are affiliated with the Fund and BFA, to the extent permitted under the Investment Company Act of 1940, as amended (the “1940 Act”). The trading activities of BFA, these Affiliates and Entities are carried out without reference to positions held directly or indirectly by the Fund and may result in BFA, an Affiliate or an Entity having positions that are adverse to those of the Fund.

No Affiliate or Entity is under any obligation to share any investment opportunity, idea or strategy with the Fund. As a result, an Affiliate or an Entity may compete with the Fund for appropriate investment opportunities. As a result of this and several other factors, the results of the Fund’s investment activities may differ from those of an

Affiliate or an Entity and of other accounts managed by an Affiliate or an Entity, and it is possible that the Fund could sustain losses during periods in which one or more Affiliates or Entities and other accounts achieve profits on their trading for proprietary or other accounts. The opposite result is also possible.

The Fund may, from time to time, enter into transactions in which BFA or an Affiliate’s or an Entity’s clients have an interest adverse to the Fund. Furthermore, transactions undertaken by Affiliate-advised clients may adversely impact the Fund. Transactions by one or more Affiliate- or Entity-advised clients or BFA may have the effect of diluting or otherwise disadvantaging the values, prices or investment strategies of the Fund.

An Entity may maintain securities indices as part of its product offerings. Index-based funds seek to track the performance of securities indices and may use the name of the index in the fund name. Index providers, including the Entities, may be paid licensing fees for use of their indices or index names. Entities will not be obligated to license their indices to BFA and its Affiliates, and BFA and its Affiliates will not be assured that the terms of any index licensing agreement with the Entities will be as favorable as those terms offered to other index licensees.

The Fund’s activities may be limited because of regulatory restrictions applicable to one or more Affiliates or Entities, and/or their internal policies designed to comply with such restrictions. In addition, the Fund may invest in securities of companies with which an Affiliate or an Entity has or is trying to develop investment banking relationships or in which an Affiliate or an Entity has significant debt or equity investments. The Fund also may invest in securities of companies for which an Affiliate or an Entity provides or may some day provide research coverage. An Affiliate or an Entity may have business relationships with and purchase or distribute or sell services or products from or to distributors, consultants or others who recommend the Fund or who engage in transactions with or for the Fund, and may receive compensation for such services. The Fund may also make brokerage and other payments to Affiliates or Entities in connection with the Fund’s portfolio investment transactions.

Pursuant to a securities lending program approved by the Board, the Fund has retained an Affiliate of BFA to serve as the securities lending agent for the Fund to the extent that the Fund participates in the securities lending program. For these services, the lending agent may receive a fee from the Fund, including a fee based on the returns earned on the Fund’s investment of the cash received as collateral for any loaned securities. In addition, one or more Affiliates may be among the entities to which the Fund may lend its portfolio securities under the securities lending program.

The activities of BFA, the Affiliates or Entities may give rise to other conflicts of interest that could disadvantage the Fund and its shareholders. BFA has adopted policies and procedures designed to address these potential conflicts of interest. See the Fund’s SAI for further information.

Shareholder Information

Additional shareholder information, including how to buy and sell shares of the Fund, is available free of charge by calling toll-free: 1-800-iShares (1-800-474-2737) or visiting our website at www.iShares.com.

Buying and Selling Shares. Shares of the Fund may be acquired or redeemed directly from the Fund only in Creation Units or multiples thereof, as discussed in the Creations and Redemptions section of this Prospectus. Only an Authorized Participant (as defined in the Creations and Redemptions section) may engage in creation or redemption transactions directly with the Fund. Once created, shares of the Fund generally trade in the secondary market in amounts less than a Creation Unit.

Shares of the Fund are listed on a national securities exchange for trading during the trading day. Shares can be bought and sold throughout the trading day like shares of other publicly-traded companies. The Trust does not impose any minimum investment for shares of the Fund purchased on an exchange. The Fund’s shares trade under the trading symbol “ACWI.”

Buying or selling Fund shares on an exchange involves two types of costs that may apply to all securities transactions. When buying or selling shares of the Fund through a broker, you will likely incur a brokerage commission or other charges determined by your broker. The commission is frequently a fixed amount and may be a significant proportional cost for investors seeking to buy or sell small amounts of shares. In addition, you may incur the cost of the “spread” – that is, any difference between the bid price and the ask price. The spread varies over time for shares of the Fund based on its trading volume and market liquidity, and is generally lower if the Fund has a lot of trading volume and market liquidity, and higher if the Fund has little trading volume and market liquidity.

The Board has adopted a policy of not monitoring for frequent purchases and redemptions of Fund shares (“frequent trading”) that appear to attempt to take advantage of a potential arbitrage opportunity presented by a lag between a change in the value of the Fund’s portfolio securities after the close of the primary markets for the Fund’s portfolio securities and the reflection of that change in the Fund’s NAV (“market timing”), because the Fund generally sells and redeems its shares directly through transactions that are in-kind and/or for cash, subject to the conditions described below under Creations and Redemptions. The Board has not adopted a policy of monitoring for other frequent trading activity because shares of the Fund are listed for trading on a national securities exchange.

The national securities exchange on which the Fund’s shares are listed is open for trading Monday through Friday and is closed on weekends and the following holidays: New Year’s Day, Martin Luther King, Jr. Day, Presidents’ Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day. The Fund’s primary listing exchange is NASDAQ.

Section 12(d)(1) of the 1940 Act restricts investments by investment companies in the securities of other investment companies. Registered investment companies are permitted to invest in the Fund beyond the limits set forth in Section 12(d)(1), subject to certain terms and conditions set forth in SEC rules or in an SEC exemptive order issued to the Trust. In order for a registered investment company to invest in shares of the Fund beyond the limitations of Section 12(d)(1) pursuant to the exemptive relief obtained by the Trust, the registered investment company must enter into an agreement with the Trust.

Book Entry. Shares of the Fund are held in book-entry form, which means that no stock certificates are issued. The Depository Trust Company (“DTC”) or its nominee is the record owner of all outstanding shares of the Fund and is recognized as the owner of all shares for all purposes.

Investors owning shares of the Fund are beneficial owners as shown on the records of DTC or its participants. DTC serves as the securities depository for shares of the Fund. DTC participants include securities brokers and dealers, banks, trust companies, clearing corporations and other institutions that directly or indirectly maintain a custodial relationship with DTC. As a beneficial owner of shares, you are not entitled to receive physical delivery of stock certificates or to have shares registered in your name, and you are not considered a registered owner of shares. Therefore, to exercise any right as an owner of shares, you must rely upon the procedures of DTC and its participants. These procedures are the same as those that apply to any other securities that you hold in book-entry or “street name” form.

Share Prices. The trading prices of the Fund’s shares in the secondary market generally differ from the Fund’s daily NAV and are affected by market forces such as supply and demand, economic conditions and other factors. Information regarding the intraday value of shares of the Fund, also known as the “indicative optimized portfolio value” (“IOPV”), is disseminated every 15 seconds throughout the trading day by the national securities exchange on which the Fund’s shares are listed or by market data vendors or other information providers. The IOPV is based on the current market value of the securities and/or cash required to be deposited in exchange for a Creation Unit. The IOPV does not necessarily reflect the precise composition of the current portfolio of securities held by the Fund at a particular point in time or the best possible valuation of the current portfolio. Therefore, the IOPV should not be viewed as a “real-time” update of the Fund’s NAV, which is computed only once a day. The IOPV is generally determined by using both current market quotations and/or price quotations obtained from broker-dealers that may trade in the portfolio securities held by the Fund. The quotations of certain Fund holdings may not be updated during U.S. trading hours if such holdings do not trade in the United States. The Fund is not involved in, or responsible for, the calculation or dissemination of the IOPV and makes no representation or warranty as to its accuracy.

Determination of Net Asset Value. The NAV of the Fund normally is determined once daily Monday through Friday, generally as of the regularly scheduled close of business of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m., Eastern time) on each day that the NYSE is open for trading, based on prices at the time of closing provided that (a) any Fund assets or liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers (as detailed below) and (b) U.S. fixed income assets may be valued as of the announced closing time for trading in fixed income instruments in a particular market or exchange. The NAV of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets held by the Fund, and its liabilities, are determined pursuant to valuation policies and procedures approved by the Board. The Fund’s assets and liabilities are valued primarily on the basis of market quotations.

Equity investments are valued at market value, which is generally determined using the last reported official closing price or last trading price on the exchange or market on which the security is primarily traded at the time of valuation.

The Fund invests in foreign securities. Foreign currency exchange rates are generally determined as of 4:00 p.m., London time. Foreign securities owned by the Fund may trade on weekends or other days when the Fund does not price its shares. As a result, the Fund’s NAV may change on days when Authorized Participants will not be able to purchase or redeem Fund shares.

Generally, trading in foreign securities, U.S. government securities, money market instruments and certain fixed-income securities is substantially completed each day at various times prior to the close of business on the NYSE. The values of such securities used in computing the NAV of the Fund are determined as of such times.

When market quotations are not readily available or are believed by BFA to be unreliable, the Fund’s investments are valued at fair value. Fair value determinations are made by BFA in accordance with policies and procedures approved by the Fund’s Board. BFA may conclude that a market quotation is not readily available or is unreliable if a security or other asset or liability does not have a price source due to its lack of liquidity, if a market quotation differs significantly from recent price quotations or otherwise no longer appears to reflect fair value, where the security or other asset or liability is thinly traded, or where there is a significant event subsequent to the most recent market quotation. A “significant event” is an event that, in the judgment of BFA, is likely to cause a material change to the closing market price of the asset or liability held by the Fund. Foreign securities whose values are affected by volatility that occurs in U.S. markets on a trading day after the close of foreign securities markets may be fair valued.

Fair value represents a good faith approximation of the value of an asset or liability. The fair value of an asset or liability held by the Fund is the amount the Fund might reasonably expect to receive from the current sale of that asset or the cost to extinguish that liability in an arm’s-length transaction. Valuing the Fund’s investments using fair value pricing will result in prices that may differ from current market valuations and that may not be the price at which those investments could have been sold during the period in which the particular fair values were used. Use of fair value prices and certain current market valuations could result in a difference between the prices used to calculate the Fund’s NAV and the prices used by the Underlying Index, which, in turn, could result in a difference between the Fund’s performance and the performance of the Underlying Index.

The value of assets or liabilities denominated in non-U.S. currencies will be converted into U.S. dollars using exchange rates deemed appropriate by BFA as investment adviser. Use of a rate different from the rate used by the Index Provider may adversely affect the Fund’s ability to track the Underlying Index.

Dividends and Distributions

General Policies. Dividends from net investment income, if any, generally are declared and paid semi-annually by the Fund. Distributions of net realized securities gains, if any, generally are declared and paid once a year, but the Trust may make distributions on a more frequent basis for the Fund. The Trust reserves the right to declare special distributions if, in its reasonable discretion, such action is necessary or advisable to preserve its status as a regulated investment company (“RIC”) or to avoid imposition of income or excise taxes on undistributed income or realized gains.

Dividends and other distributions on shares of the Fund are distributed on a pro rata basis to beneficial owners of such shares. Dividend payments are made through DTC participants and indirect participants to beneficial owners then of record with proceeds received from the Fund.

Dividend Reinvestment Service. No dividend reinvestment service is provided by the Trust. Broker-dealers may make available the DTC book-entry Dividend Reinvestment Service for use by beneficial owners of the Fund for reinvestment of their dividend distributions. Beneficial owners should contact their broker to determine the availability and costs of the service and the details of participation therein. Brokers may require beneficial owners to adhere to specific procedures and timetables. If this service is available and used, dividend distributions of both income and realized gains will be automatically reinvested in additional whole shares of the Fund purchased in the secondary market.

Taxes. As with any investment, you should consider how your investment in shares of the Fund will be taxed. The tax information in this Prospectus is provided as general information, based on current law. You should consult your own tax professional about the tax consequences of an investment in shares of the Fund.

Unless your investment in Fund shares is made through a tax-exempt entity or tax-deferred retirement account, such as an IRA, you need to be aware of the possible tax consequences when the Fund makes distributions or you sell Fund shares.

Taxes on Distributions. Distributions from the Fund’s net investment income (other than qualified dividend income), including distributions of income from securities lending and distributions out of the Fund’s net short-term capital gains, if any, are taxable to you as ordinary income. Distributions by the Fund of net long-term capital gains in excess of net short-term capital losses (capital gain dividends) are taxable to you as long-term capital gains, generally at a 15% tax rate (0% at certain income levels), regardless of how long you have held the Fund’s shares. Distributions by the Fund that qualify as qualified dividend income are taxable to you at long-term capital gain rates for taxable years beginning on or before December 31, 2012. The 15% and 0% tax rates expire for taxable years beginning after December 31, 2012. Maximum long-term capital gain income tax rates are scheduled to rise to 20% in 2013. Beginning in 2013, a 3.8% U.S. federal Medicare contribution tax will be imposed on “net investment income,” including interest, dividends, and capital gains, of U.S. individuals with income exceeding $200,000 (or $250,000 if married and filing jointly), and of estates and trusts.

Dividends will be qualified dividend income to you if they are attributable to qualified dividend income received by the Fund. Generally, qualified dividend income includes dividend income from taxable U.S. corporations and qualified non-U.S. corporations, provided that the Fund satisfies certain holding period requirements in respect of the stock of such corporations and has not hedged its position in the stock in certain ways. Substitute dividends received by the Fund with respect to dividends paid on securities lent out will not be qualified dividend income. For this purpose, a qualified non-U.S. corporation means any non-U.S. corporation that is eligible for benefits under a comprehensive income tax treaty with the United States, which includes an exchange of information program or if the stock with respect to which the dividend was paid is readily tradable on an established United States securities market. The term excludes a corporation that is a passive foreign investment company.

Dividends received by the Fund from a real estate investment trust (“REIT”) or another RIC generally are qualified dividend income only to the extent the dividend distributions are made out of qualified dividend income received by such REIT or RIC. It is expected that dividends received by the Fund from a REIT and distributed to a shareholder generally will be taxable to the shareholder as ordinary income.

For a dividend to be treated as qualified dividend income, the dividend must be received with respect to a share of stock held without being hedged by the Fund, and with respect to a share of the Fund held without being hedged by you, for 61 days during the 121-day period beginning at the date which is 60 days before the date on which such share becomes ex-dividend with respect to such dividend or, in the case of certain preferred stock, 91 days during the 181-day period beginning 90 days before such date.

If your Fund shares are loaned out pursuant to a securities lending arrangement, you may lose the ability to use foreign tax credits passed through by the Fund or to treat Fund dividends paid while the shares are held by the borrower as qualified dividend income.

In general, your distributions are subject to U.S. federal income tax for the year when they are paid. Certain distributions paid in January, however, may be treated as paid on December 31 of the prior year.

If the Fund’s distributions exceed current and accumulated earnings and profits, all or a portion of the distributions made in the taxable year may be recharacterized as a return of capital to shareholders. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and result in a higher capital gain or lower capital loss when those shares on which the distribution was received are sold. Once a shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain, if the shareholder holds shares of the Fund as capital assets.

If you are neither a resident nor a citizen of the United States or if you are a non-U.S. entity, the Fund’s ordinary income dividends (which include distributions of net short-term capital gains) will generally be subject to a 30% U.S. withholding tax, unless a lower treaty rate applies, provided that withholding tax will generally not apply to any gain or income realized by a non-U.S. shareholder in respect of any distributions of long-term capital gains or upon the sale or other disposition of shares of the Fund.

A 30% withholding tax will be imposed on dividends paid after December 31, 2013, and redemption proceeds paid after December 31, 2014, to (i) foreign financial institutions including non-U.S. investment funds unless they agree to collect and disclose to the Internal Revenue Service (“IRS”) information regarding their direct and indirect U.S. account holders and (ii) certain other foreign entities, unless they certify certain information regarding their direct and indirect U.S. owners. To avoid withholding, foreign financial institutions will need to enter into agreements with the IRS that state that they will provide the IRS information, including the name, address and taxpayer identification number of direct and indirect U.S. account holders, comply with due diligence procedures with respect to the identification of U.S. accounts, report to the IRS certain information with respect to U.S. accounts maintained, agree to withhold tax on certain payments made to non-compliant foreign financial institutions or to account holders who fail to provide the required information, and determine certain other information as to their account holders. Other foreign entities will need to provide the name, address, and taxpayer identification number of each substantial U.S. owner or certifications of no substantial U.S. ownership unless certain exceptions apply.

Dividends, interest and capital gains earned by the Fund with respect to non-U.S. securities may give rise to withholding and other taxes imposed by non-U.S. countries. Tax conventions between certain countries and the United States may reduce or eliminate such taxes. If more than 50% of the total assets of the Fund at the close of a year consists of non-U.S. stocks or securities, the Fund may “pass through” to you certain non-U.S. income taxes (including withholding taxes) paid by the Fund. This means that you would be considered to have received as an additional dividend your share of such non-U.S. taxes, but you may be entitled to either a corresponding tax deduction in calculating your taxable income, or, subject to certain limitations, a credit in calculating your U.S. federal income tax.

For purposes of foreign tax credits for U.S. shareholders of the Fund, foreign capital gains taxes may not produce associated foreign source income, thereby limiting a U.S. person’s ability to use such credits.

If you are a resident or a citizen of the United States, by law, back-up withholding will apply to your distributions and proceeds if you have not provided a taxpayer identification number or social security number and made other required certifications.

Taxes When Shares are Sold. Currently, any capital gain or loss realized upon a sale of Fund shares is generally treated as a long-term gain or loss if the shares have been held for more than one year. Any capital gain or loss realized upon a sale of Fund shares held for one year or less is generally treated as short-term gain or loss, except that any capital loss on the sale of shares held for six months or less is treated as long-term capital loss to the extent that capital gain dividends were paid with respect to such shares. Beginning in 2013, any such capital gains, including from sales of Fund shares or from capital gain dividends, will be included in “net investment income” for purposes of the 3.8% U.S. federal Medicare contribution tax mentioned above.

The foregoing discussion summarizes some of the consequences under current U.S. federal tax law of an investment in the Fund. It is not a substitute for personal tax advice. You may also be subject to state and local taxation on Fund distributions and sales of

shares. Consult your personal tax adviser about the potential tax consequences of an investment in shares of the Fund under all applicable tax laws.

Creations and Redemptions. Prior to trading in the secondary market, shares of the Fund are “created” at NAV by market makers, large investors and institutions only in block-size Creation Units of 100,000 shares or multiples thereof. Each “creator” or “Authorized Participant” enters into an authorized participant agreement with the Fund’s distributor, SEI Investments Distribution Co. (the “Distributor”). Only an Authorized Participant may create or redeem Creation Units directly with the Fund. A creation transaction, which is subject to acceptance by the transfer agent, generally takes place when an Authorized Participant deposits into the Fund a designated portfolio of securities and a specified amount of cash approximating the holdings of the Fund in exchange for a specified number of Creation Units. To the extent practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund.

Similarly, shares can be redeemed only in Creation Units, generally for a designated portfolio of securities and a specified amount of cash held by the Fund (“Fund Securities”). Except when aggregated in Creation Units, shares are not redeemable by the Fund. The prices at which creations and redemptions occur are based on the next calculation of NAV after an order is received in a form described in the authorized participant agreement.

The Fund intends to comply with the U.S. federal securities laws in accepting securities for deposit and satisfying redemptions with redemption securities by, among other means, assuring that any securities accepted for deposit and any securities used to satisfy redemption requests will be sold in transactions that would be exempt from registration under the Securities Act of 1933, as amended (the “1933 Act”). Further, an Authorized Participant that is not a “qualified institutional buyer,” as such term is defined under Rule 144A of the 1933 Act, will not be able to receive Fund Securities that are restricted securities eligible for resale under Rule 144A.

Creations and redemptions must be made through a firm that is either a member of the Continuous Net Settlement System of the National Securities Clearing Corporation or a DTC participant and has executed an agreement with the Distributor with respect to creations and redemptions of Creation Unit aggregations. Information about the procedures regarding creation and redemption of Creation Units (including the cut-off times for receipt of creation and redemption orders) is included in the Fund’s SAI.

Because new shares may be created and issued on an ongoing basis, at any point during the life of the Fund a “distribution,” as such term is used in the 1933 Act, may be occurring. Broker-dealers and other persons are cautioned that some activities on their part may, depending on the circumstances, result in their being deemed participants in a distribution in a manner that could render them statutory underwriters and subject to the prospectus delivery and liability provisions of the 1933 Act. Any determination of whether one is an underwriter must take into account all the relevant facts and circumstances of each particular case.

Broker-dealers should also note that dealers who are not “underwriters” but are participating in a distribution (as contrasted to ordinary secondary transactions), and

thus dealing with shares that are part of an “unsold allotment” within the meaning of Section 4(3)(C) of the 1933 Act, would be unable to take advantage of the prospectus delivery exemption provided by Section 4(3) of the 1933 Act. For delivery of prospectuses to exchange members, the prospectus delivery mechanism of Rule 153 under the 1933 Act is available only with respect to transactions on a national securities exchange.

Costs Associated with Creations and Redemptions. Authorized Participants are charged standard creation and redemption transaction fees to offset transfer and other transaction costs associated with the issuance and redemption of Creation Units. The standard creation and redemption transaction fees are set forth in the table below. The standard creation transaction fee is charged to the Authorized Participant on the day such Authorized Participant creates a Creation Unit, and is the same regardless of the number of Creation Units purchased by the Authorized Participant on the applicable business day. Similarly, the standard redemption transaction fee is charged to the Authorized Participant on the day such Authorized Participant redeems a Creation Unit, and is the same regardless of the number of Creation Units redeemed by the Authorized Participant on the applicable business day. Creations and redemptions for cash (when cash creations and redemptions (in whole or in part) are available or specified) are also subject to an additional charge (up to the maximum amounts shown in the table below). This charge is intended to compensate for brokerage, tax, foreign exchange, execution, market impact and other costs and expenses related to cash transactions. Investors who use the services of a broker or other financial intermediary may pay fees for such services.

The following table shows, as of September 30, 2011, the approximate value of one Creation Unit, standard fees and maximum additional charges for creations and redemptions (as described above):

Householding. Householding is an option available to certain Fund investors. Householding is a method of delivery, based on the preference of the individual investor, in which a single copy of certain shareholder documents can be delivered to investors who share the same address, even if their accounts are registered under different names. Please contact your broker-dealer if you are interested in enrolling in householding and receiving a single copy of prospectuses and other shareholder documents, or if you are currently enrolled in householding and wish to change your householding status.

Distribution

The Distributor distributes Creation Units for the Fund on an agency basis. The Distributor does not maintain a secondary market in shares of the Fund. The Distributor has no role in determining the policies of the Fund or the securities that are purchased or sold by the Fund. The Distributor’s principal address is One Freedom Valley Drive, Oaks, PA 19456.

In addition, BFA or its Affiliates make payments to broker-dealers, banks or other financial intermediaries (together, “intermediaries”) related to marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems, or their making shares of the Fund and certain other iShares funds available to their customers. Such payments, which may be significant to the intermediary, are not made by the Fund. Rather, such payments are made by BFA or its Affiliates from their own resources, which come directly or indirectly in part from fees paid by the iShares funds complex. Payments of this type are sometimes referred to as revenue-sharing payments. A financial intermediary may make decisions about which investment options it recommends or makes available, or the level of services provided, to its customers based on the revenue-sharing payments it is eligible to receive. Therefore, such payments to an intermediary create conflicts of interest between the intermediary and its customers and may cause the intermediary to recommend the Fund or other iShares funds over another investment. More information regarding these payments is contained in the Fund’s SAI. Please contact your salesperson or other investment professional for more information regarding any such payments his or her firm may receive from BFA or its Affiliates.

Financial Highlights

The financial highlights table is intended to help investors understand the Fund’s financial performance since inception. Certain information reflects financial results for a single share of the Fund. The total returns in the table represent the rate that an investor would have earned (or lost) on an investment in the Fund, assuming reinvestment of all dividends and distributions. This information has been audited by PricewaterhouseCoopers LLP, whose report is included, along with the Fund’s financial statements, in the Fund’s Annual Report (available upon request).

Supplemental Information

I. Premium/Discount Information

The table that follows presents information about the differences between the daily market price on secondary markets for shares of the Fund and the Fund’s NAV. NAV is the price at which the Fund issues and redeems shares. It is calculated in accordance with the standard formula for valuing mutual fund shares. The price used to calculate market returns (“Market Price”) of the Fund generally is determined using the midpoint between the highest bid and the lowest offer on the primary securities exchange on which shares of the Fund are listed for trading, as of the time that the Fund’s NAV is calculated. The Fund’s Market Price may be at, above or below its NAV. The NAV of the Fund will fluctuate with changes in the value of its portfolio holdings. The Market Price of the Fund will fluctuate in accordance with changes in its NAV, as well as market supply and demand.

Premiums or discounts are the differences (expressed as a percentage) between the NAV and Market Price of the Fund on a given day, generally at the time the NAV is calculated. A premium is the amount that the Fund is trading above the reported NAV, expressed as a percentage of the NAV. A discount is the amount that the Fund is trading below the reported NAV, expressed as a percentage of the NAV.

The following information shows the frequency of distributions of premiums and discounts for the Fund for each full calendar quarter of 2010 through September 30, 2011.

Each line in the table shows the number of trading days in which the Fund traded within the premium/discount range indicated. The number of trading days in each premium/discount range is also shown as a percentage of the total number of trading days in the period covered by the table. All data presented here represents past performance, which cannot be used to predict future results.

II. Total Return Information

The table that follows presents information about the total returns of the Fund and the Underlying Index as of the fiscal year ended July 31, 2011.

“Average Annual Total Returns” represent the average annual change in value of an investment over the periods indicated. “Cumulative Total Returns” represent the total change in value of an investment over the period indicated.

The Fund’s NAV is the value of one share of the Fund as calculated in accordance with the standard formula for valuing mutual fund shares. The NAV return is based on the NAV of the Fund and the market return is based on the Market Price of the Fund. Market Price is determined by using the midpoint between the highest bid and the lowest offer on the primary stock exchange on which shares of the Fund are listed for trading, as of the time that the Fund’s NAV is calculated. Since shares of the Fund did not trade in the secondary market until after the Fund’s inception, for the period from inception to the first day of secondary market trading in shares of the Fund, the NAV of the Fund is used as a proxy for the Market Price to calculate market returns. Market and NAV returns assume that dividends and capital gain distributions have been reinvested in the Fund at Market Price and NAV, respectively.

An index is a statistical composite that tracks a specified financial market or sector. Unlike the Fund, the Underlying Index does not actually hold a portfolio of securities and therefore does not incur the expenses incurred by the Fund. These expenses negatively impact the performance of the Fund. Also, market returns do not include brokerage commissions that may be payable on secondary market transactions. If brokerage commissions were included, market returns would be lower. The returns shown in the following table do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption or sale of Fund shares. The investment return and principal value of shares of the Fund will vary with changes in market conditions. Shares of the Fund may be worth more or less than their original cost when they are redeemed or sold in the market. The Fund’s past performance is no guarantee of future results.

Fund Overview

iSHARES® MSCI ALL COUNTRY ASIA
ex JAPAN INDEX FUND

Ticker: AAXJ Stock Exchange: NASDAQ

Investment Objective

The iShares MSCI All Country Asia ex Japan Index Fund (the “Fund”) seeks investment results that correspond generally to the price and yield performance, before fees and expenses, of the MSCI All Country Asia ex Japan Index (the “Underlying Index”).

Fees and Expenses

The following table describes the fees and expenses that you will incur if you own shares of the Fund. The investment advisory agreement between iShares Trust (the “Trust”) and BlackRock Fund Advisors (“BFA”) (the “Investment Advisory Agreement”) provides that BFA will pay all operating expenses of the Fund, except interest expenses, taxes, brokerage expenses, future distribution fees or expenses, and extraordinary expenses. “Acquired Fund Fees and Expenses” reflect the Fund’s pro rata share of the fees and expenses incurred by investing in other investment companies. The impact of Acquired Fund Fees and Expenses is included in the total returns of the Fund. Acquired Fund Fees and Expenses are not used to calculate the Fund’s net asset value per share (“NAV”) and are not included in the calculation of the ratio of expenses to average net assets shown in the Financial Highlights section of the Fund’s prospectus (the “Prospectus”). BFA, the investment adviser to the Fund, has contractually agreed to waive its management fees in an amount equal to the Acquired Fund Fees and Expenses attributable to the Fund’s investments in other iShares funds through June 30, 2013. The contractual waiver may be terminated prior to June 30, 2013 only upon written agreement of the Trust and BFA.

You may also incur usual and customary brokerage commissions when buying or selling shares of the Fund, which are not reflected in the example that follows:

Example. This Example is intended to help you compare the cost of owning shares of the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

1 Year
3 Years
5 Years
10 Years
$68 $216 $377 $845

Portfolio Turnover. The Fund may pay transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 41% of the average value of its portfolio.

Principal Investment Strategies

As of September 30, 2011, the Underlying Index is a free float-adjusted market capitalization index designed to measure equity market performance of the following 12 developed and emerging market countries or regions: Australia, China, Hong Kong, India, Indonesia, Malaysia, New Zealand, the Philippines, Singapore, South Korea, Taiwan and Thailand. Component companies include consumer discretionary, financial, industrial and information technology companies.

BFA uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to “beat” the index it tracks and does not seek temporary defensive positions when markets decline or appear overvalued.

Indexing may eliminate the chance that the Fund will substantially outperform the Underlying Index but also may reduce some of the risks of active management, such as poor security selection. Indexing seeks to achieve lower costs and better after-tax performance by keeping portfolio turnover low in comparison to actively managed investment companies.

BFA uses a representative sampling indexing strategy to manage the Fund. “Representative sampling” is an indexing strategy that involves investing in a representative sample of securities that collectively has an investment profile similar to the Underlying Index. The securities selected are expected to have, in the aggregate, investment characteristics (based on factors such as market capitalization and industry weightings), fundamental characteristics (such as return variability and yield) and liquidity measures similar to those of the Underlying Index. The Fund may or may not hold all of the securities in the Underlying Index.



S-2   


Table Of Contents



The Fund generally invests at least 90% of its assets in securities of the Underlying Index and in depositary receipts representing securities of the Underlying Index. The Fund may invest the remainder of its assets in securities not included in the Underlying Index, but which BFA believes will help the Fund track the Underlying Index and in other investments including futures contracts, options on futures contracts, options and swaps as well as cash and cash equivalents, including shares of money market funds advised by BFA or its affiliates.


The Fund invests all of its assets that are invested in India in a wholly-owned subsidiary located in the Republic of Mauritius (the “Subsidiary”). BFA serves as investment adviser to both the Fund and the Subsidiary. Unless otherwise indicated, the term “Fund,” as used in this Prospectus, means the Fund and/or the Subsidiary, as applicable.

The Fund may lend securities representing up to one-third of the value of the Fund’s total assets (including the value of the collateral received).

The Underlying Index is sponsored by an organization (the “Index Provider”) that is independent of the Fund and BFA. The Index Provider determines the composition and relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index. The Fund’s Index Provider is MSCI Inc. (“MSCI”).

Industry Concentration Policy. The Fund will concentrate its investments (i.e., hold 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. For purposes of this limitation, securities of the U.S. government (including its agencies and instrumentalities) and repurchase agreements collateralized by U.S. government securities are not considered to be issued by members of any industry.

Summary of Principal Risks

As with any investment, you could lose all or part of your investment in the Fund, and the Fund’s performance could trail that of other investments. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund’s NAV, trading price, yield, total return and ability to meet its investment objective.

Asset Class Risk. Securities in the Underlying Index or in the Fund’s portfolio may underperform in comparison to the general securities markets or other asset classes.

Concentration Risk. To the extent that the Fund’s investments are concentrated in a particular issuer, region, country, market, industry or asset class, the Fund may be susceptible to loss due to adverse occurrences affecting that issuer, region, country, market, industry or asset class.

Consumer Discretionary Sector Risk. The consumer discretionary sector may be affected by changes in domestic and international economies, exchange and interest rates, competition, consumers’ disposable income and consumer preferences, social trends and marketing campaigns.

Currency Risk. Because the Fund’s NAV is determined in U.S. dollars, the Fund’s NAV could decline if the currency

S-3   


Table Of Contents



of a non-U.S. market in which the Fund invests depreciates against the U.S. dollar.

Custody Risk. Less developed markets are more likely to experience problems with the clearing and settling of trades and the holding of securities by local banks, agents and depositories.

Emerging Markets Risk. The Fund’s investments in emerging markets may be subject to a greater risk of loss than investments in more developed markets. Emerging markets may be more likely to experience inflation risk, political turmoil and rapid changes in economic conditions than more developed markets. Emerging markets often have less uniformity in accounting and reporting requirements, unreliable securities valuation and greater risk associated with custody of securities.

Equity Securities Risk. Equity securities are subject to changes in value and their values may be more volatile than other asset classes.

Financial Sector Risk. Performance of companies in the financial sector may be adversely impacted by many factors, including, among others, government regulations, economic conditions, credit rating downgrades, changes in interest rates, and decreased liquidity in credit markets. This sector has experienced significant losses in the recent past, and the impact of more stringent capital requirements and of recent or future regulation on any individual financial company or on the sector as a whole cannot be predicted.

Geographic Risk. A natural or other disaster could occur in a geographic region in which the Fund invests, which could affect the economy or particular business operations of companies in the specific geographic region, causing an adverse impact on the Fund’s investments in the affected region.

Industrials Sector Risk. The industrials sector is affected by changes in the supply and demand for products and services, product obsolescence, claims for environmental damage or product liability and general economic conditions, among other factors.

Information Technology Sector Risk. Information technology companies face intense competition and potentially rapid product obsolescence. They are also heavily dependent on intellectual property rights and may be adversely affected by loss or impairment of those rights.

Issuer Risk. Fund performance depends on the performance of individual securities to which the Fund has exposure. Changes to the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline.

Lack of Natural Resources Risk. Certain economies to which the Fund may be exposed have few natural resources. Any fluctuation or shortage in the commodity markets could have a negative impact on those economies.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA’s investment management strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares, losses from

S-4   


Table Of Contents



trading in secondary markets, periods of high volatility and disruption in the creation/redemption process of the Fund. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV.

Non-Diversification Risk. The Fund may invest a large percentage of its assets in securities issued by or representing a small number of issuers. As a result, the Fund’s performance may depend on the performance of a small number of issuers.

Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers are subject to the risks associated with investing in those non-U.S. markets, such as heightened risks of inflation or nationalization. The Fund may lose money due to political, economic and geographic events affecting a non-U.S. issuer or market.

Passive Investment Risk. The Fund is not actively managed and BFA does not attempt to take defensive positions under any market conditions, including declining markets.

Privatization Risk. Some countries in which the Fund invests have begun a process of privatizing certain entities and industries. Privatized entities may lose money or be re-nationalized.

Reliance on Trading Partners Risk. The Fund invests in countries whose economies are heavily dependent upon trading with key partners. Any reduction in this trading may have an adverse impact on the Fund’s investments.

Risk of Investing in China. China may be subject to considerable degrees of economic, political and social instability.

Risk of Investing in India. Investment in Indian issuers involves risks that are specific to India, including legal, regulatory, political and economic risks. The securities markets in India are relatively underdeveloped and may subject the Fund to higher transaction costs or greater uncertainty than investments in more developed securities markets. Such risks may adversely affect the value of the Fund’s investments.

Risk of Investing in South Korea. The Fund’s investments in South Korean issuers may subject the Fund to legal, regulatory, political, currency, security, and economic risks that are specific to South Korea. In addition, economic and political developments of South Korean neighbors may have an adverse effect on the South Korean economy. As a result, such risks may adversely affect the value of the Fund’s investments.

Securities Lending Risk. The Fund may engage in securities lending. Securities lending involves the risk that the Fund may lose money because the borrower of the Fund’s loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Security Risk. Some countries and regions in which the Fund invests have experienced security concerns. Incidents involving a country’s or region’s security may cause uncertainty in these markets and may adversely affect their economies and the Fund’s investments.

Structural Risk. The countries in which the Fund invests may be subject to

S-5   


Table Of Contents



considerable degrees of economic, political and social instability.

Tracking Error Risk. The performance of the Fund may diverge from that of the Underlying Index. Because the Fund employs a representative sampling strategy, the Fund may experience tracking error to a greater extent than a fund that seeks to replicate an index. BFA EXPECTS THAT THE FUND MAY EXPERIENCE HIGHER TRACKING ERROR THAN IS TYPICAL FOR SIMILAR INDEX EXCHANGE-TRADED FUNDS.

Treaty/Tax Risk. The Fund and the Subsidiary rely on the Double Tax Avoidance Agreement between India and Mauritius (“DTAA”) for relief from certain Indian taxes. Treaty renegotiation or legislative changes may result in higher taxes and lower returns for the Fund.

Valuation Risk. The value of the securities in the Fund’s portfolio may change on days when shareholders will not be able to purchase or sell the Fund’s shares.

1 After-tax returns in the table above are calculated using the historical highest individual U.S. federal marginal income tax rates and do not reflect the impact of state or local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown, and after-tax returns shown are not relevant to tax-exempt investors or investors who hold shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts (“IRAs”). Fund returns after taxes on distributions and sale of Fund shares are calculated assuming that an investor has sufficient capital gains of the same character from other investments to offset any capital losses from the sale of Fund shares. As a result, Fund returns after taxes on distributions and sale of Fund shares may exceed Fund returns before taxes and/or returns after taxes on distributions.

Management

Investment Adviser. BlackRock Fund Advisors.

Portfolio Managers. Christopher Bliss, Rene Casis, Diane Hsiung and Greg Savage (the “Portfolio Managers”) are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager supervises a portfolio management team. Mr. Bliss has been a Portfolio Manager of the Fund since 2011. Mr. Casis has been a Portfolio Manager of the Fund since 2010. Ms. Hsiung and Mr. Savage have been Portfolio Managers of the Fund since 2008.

Purchase and Sale of Fund Shares

The Fund is an exchange-traded fund (commonly referred to as an “ETF”). Individual Fund shares may only be purchased and sold on a national securities exchange through a broker-dealer. The price of Fund shares is based on market price, and because ETF shares trade at market prices rather than NAV, shares may trade at a price greater than NAV (a premium) or less than NAV (a discount). The Fund will only issue or redeem shares that have been aggregated into blocks of 100,000 shares or multiples thereof (“Creation Units”) to authorized participants who have entered into agreements with the Fund’s distributor. The Fund generally will issue or redeem Creation Units in return for a designated portfolio of securities (and an amount of cash) that the Fund specifies each day.

Tax Information

The Fund intends to make distributions that may be taxable to you as ordinary income or capital gains, unless you are investing through a tax-deferred arrangement such as a 401(k) plan or an IRA.

Payments to Broker-Dealers and other Financial Intermediaries

If you purchase shares of the Fund through a broker-dealer or other financial intermediary (such as a bank), BFA or other related companies may pay the intermediary for marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems or other services related to the sale or promotion of the Fund. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.

More Information About the Fund

This Prospectus contains important information about investing in the Fund. Please read this Prospectus carefully before you make any investment decisions. Additional information regarding the Fund is available at www.iShares.com.

BFA is the investment adviser to the Fund. Shares of the Fund are listed for trading on The NASDAQ Stock Market (“NASDAQ”). The market price for a share of the Fund may be different from the Fund’s most recent NAV.

ETFs are funds that trade like other publicly-traded securities. The Fund is designed to track an index. Similar to shares of an index mutual fund, each share of the Fund represents a partial ownership in an underlying portfolio of securities intended to track a market index. Unlike shares of a mutual fund, which can be bought and redeemed from the issuing fund by all shareholders at a price based on NAV, shares of the Fund may be purchased or redeemed directly from the Fund at NAV solely by authorized participants. Also unlike shares of a mutual fund, shares of the Fund are listed on a national securities exchange and trade in the secondary market at market prices that change throughout the day.

The Fund invests in a particular segment of the securities markets and seeks to track the performance of a securities index that generally is not representative of the market as a whole. The Fund is designed to be used as part of broader asset allocation strategies. Accordingly, an investment in the Fund should not constitute a complete investment program.

An index is a theoretical financial calculation while the Fund is an actual investment portfolio. The performance of the Fund and the Underlying Index may vary due to transaction costs, non-U.S. currency valuations, asset valuations, corporate actions (such as mergers and spin-offs), timing variances and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions (such as diversification requirements) that apply to the Fund but not to the Underlying Index or to the use of representative sampling. “Tracking error” is the difference between the performance (return) of the Fund’s portfolio and that of the Underlying Index. BFA expects that, over time, the Fund’s tracking error will not exceed 5%. Because the Fund uses a representative sampling indexing strategy, it can be expected to have a larger tracking error than if it used a replication indexing strategy. “Replication” is an indexing strategy in which a fund invests in substantially all of the securities in its underlying index in approximately the same proportions as in the underlying index.

An investment in the Fund is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, BFA or any of its affiliates.

The Fund’s investment objective and the Underlying Index may be changed without shareholder approval.

A Further Discussion of Principal Risks

The Fund is subject to various risks, including the principal risks noted below, any of which may adversely affect the Fund’s NAV, trading price, yield, total return and ability to meet its investment objective. You could lose all or part of your investment in the Fund, and the Fund could underperform other investments.

Asian Security Risk. Some countries and regions in which the Fund invests have experienced acts of terrorism or strained international relations due to territorial disputes, historical animosities or other defense concerns. For example, North and South Korea each have substantial military capabilities, and historical local tensions between the two present the risk of war. Any outbreak of hostilities between the two countries could have a severe adverse effect on the South Korean economy and securities markets. These situations may cause uncertainty in the markets of these geographic areas and may adversely affect the performance of their economies.

Asian Structural Risk. Certain Asian countries are subject to a considerable degree of economic, political and social instability, which could adversely affect the Fund’s investments:

  • Asian Economic Risk. Certain Asian economies have experienced over-extension of credit, currency devaluations and restrictions, high unemployment, high inflation, decreased exports and economic recessions. Economic events in any one Asian country can have a significant effect on the entire Asian region as well as on major trading partners outside Asia, and any adverse effect on some or all of the Asian countries and regions in which the Fund invests. The securities markets in some Asian economies are relatively underdeveloped and may subject the Fund to higher transaction costs or greater uncertainty than investments in more developed securities markets. Such risks may adversely affect the value of the Fund’s investments.
  • Government Control and Regulations. Governments of many Asian countries have implemented significant economic reforms in order to liberalize trade policy, promote foreign investment in their economies, reduce government control of the economy and develop market mechanisms. There can be no assurance these reforms will continue or that they will be effective. Despite recent reform and privatizations, significant regulation of investment and industry is still pervasive in many Asian countries and may restrict foreign ownership of domestic corporations and repatriation of assets, which may adversely affect Fund investments.
  • Political and Social Risk. Governments in some Asian countries are authoritarian in nature, have been installed or removed as a result of military coups or have periodically used force to suppress civil dissent. Disparities of wealth, the pace and success of democratization and ethnic, religious and racial disaffection have led to social turmoil, violence and labor unrest in some countries. Unanticipated or sudden political or social developments may result in sudden and significant investment losses.
  • Expropriation Risk. Investing in certain Asian countries involves risk of loss due to expropriation, nationalization, or confiscation of assets and property or the imposition of restrictions on foreign investments and on repatriation of capital invested.

Asset Class Risk. The securities in the Underlying Index or in the Fund’s portfolio may underperform the returns of other securities or indexes that track other countries, groups of countries, regions, industries, groups of industries, markets, asset classes or sectors. Various types of securities or indexes tend to experience cycles of outperformance and underperformance in comparison to the general securities markets.

Concentration Risk. To the extent that the Fund’s portfolio reflects the Underlying Index’s concentration in the securities of a particular issuer or issuers in a particular country, group of countries, region, market, industry, group of industries, sector or asset class, the Fund may be adversely affected by the performance of those securities, may be subject to increased price volatility and may be more susceptible to adverse economic, market, political or regulatory occurrences affecting that issuer, country, group of countries, region, market, industry, group of industries, sector or asset class.

Consumer Discretionary Sector Risk. The success of consumer product manufacturers and retailers is tied closely to the performance of domestic and international economies, interest rates, exchange rates, competition, consumer confidence, changes in demographics and consumer preferences. Companies in the consumer discretionary sector depend heavily on disposable household income and consumer spending, and may be strongly affected by social trends and marketing campaigns. These companies may be subject to severe competition, which may have an adverse impact on their profitability.

Currency Risk. Because the Fund’s NAV is determined on the basis of the U.S. dollar, investors may lose money if the currency of a non-U.S. market in which the Fund invests depreciates against the U.S. dollar, even if the local currency value of the Fund’s holdings in that market increases.

Custody Risk. Custody risk refers to the risks inherent in the process of clearing and settling trades and the holding of securities by local banks, agents and depositories. Low trading volumes and volatile prices in less developed markets may make trades harder to complete and settle, and governments or trade groups may compel local agents to hold securities in designated depositories that are not subject to independent evaluation. Local agents are held only to the standards of care of their local markets. In general, the less developed a country’s securities market is, the greater the likelihood of custody problems.

Emerging Markets Risk. Investments in emerging markets are subject to a greater risk of loss than investments in more developed markets. This is due to, among other things, the potential for greater market volatility, lower trading volume, inflation, political and economic instability, greater risk of a market shutdown and more governmental limitations on foreign investments than typically found in more developed markets. In addition, emerging markets often have less uniformity in

accounting and reporting requirements, unreliable securities valuation and greater risks associated with custody of securities.

Equity Securities Risk. The Fund invests in equity securities, which are subject to changes in value that may be attributable to market perception of a particular issuer or to general stock market fluctuations that affect all issuers. Investments in equity securities may be more volatile than investments in other asset classes.

Financial Sector Risk. Companies in the financial sector of an economy are often subject to governmental regulation and, recently, government intervention and the potential for additional regulation, which may adversely affect the scope of their activities, the prices they can charge and the amount of capital they must maintain. Governmental regulation may change frequently and may have significant adverse consequences for companies in the financial sector, including effects not intended by such regulation. The impact of recent or future regulation in various countries on any individual financial company or on the sector as a whole cannot be predicted. Certain risks may impact the value of investments in the financial sector more severely than investments outside this sector, including the risks associated with companies that operate with substantial financial leverage. Companies in the financial sector may also be adversely affected by increases in interest rates and loan losses, decreases in the availability of money or asset valuations, credit rating downgrades and adverse conditions in other related markets. Over the past few years, the deterioration of the credit markets has impacted a broad range of mortgage, asset-backed, auction rate, sovereign debt and other markets, including U.S. and non-U.S. credit and interbank money markets, thereby affecting a wide range of financial institutions and markets. This situation has created instability in the financial markets and caused certain financial companies to incur large losses. Some financial companies have experienced declines in the valuations of their assets, taken actions to raise capital (such as the issuance of debt or equity securities), or even ceased operations. Some financial companies have borrowed significant amounts of capital from governments and may face future government-imposed restrictions on their businesses or increased government intervention. These actions have caused the securities of many financial companies to decline in value. Insurance companies, in particular, may be subject to severe price competition, which may have an adverse impact on their profitability.

Geographic Risk. Some markets in which the Fund invests are located in parts of the world that have historically been prone to natural disasters, such as earthquakes, volcanoes, droughts, floods, hurricanes and tsunamis, and are economically sensitive to environmental events. Any natural or other disaster could have a significant adverse impact on the economies of these geographic areas, causing an adverse impact on the Fund’s investments in the affected region.

Industrials Sector Risk. The stock prices of companies in the industrials sector are affected by supply and demand, both for their specific product or service and for industrials sector products in general. The products of manufacturing companies may face obsolescence due to rapid technological developments and frequent new product introduction. Government regulations, world events, economic conditions and exchange rates affect the performance of companies in the industrials sector. Companies in the industrials sector may be adversely affected by liability for

environmental damage, product liability claims and exchange rates. The industrials sector may also be adversely affected by changes or trends in commodity prices, which may be influenced by unpredictable factors.

Information Technology Sector Risk. Information technology companies face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Like other technology companies, information technology companies may have limited product lines, markets, financial resources or personnel. The products of information technology companies may face obsolescence due to rapid technological developments and frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Companies in the information technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies.

Issuer Risk. The performance of the Fund depends on the performance of individual securities to which the Fund has exposure. Any issuer of these securities may perform poorly, causing the value of its securities to decline. Poor performance may be caused by poor management decisions, competitive pressures, changes in technology, expiration of patent protection, disruptions in supply, labor problems or shortages, corporate restructurings, fraudulent disclosures or other factors. Issuers may, in times of distress or at their own discretion, decide to reduce or eliminate dividends, which may also cause their stock prices to decline.

Lack of Natural Resources Risk. Singapore and Taiwan are small island states with few raw material resources and limited land area and each is reliant on imports for its commodity needs. Any fluctuations or shortages in the commodity markets would have a great impact on the Singaporean and Taiwanese economies. Singapore and Taiwan are also sensitive to the political and economic developments of their neighbors.

Management Risk. The Fund may not fully replicate the Underlying Index and may hold securities not included in the Underlying Index. As a result, the Fund is subject to the risk that BFA’s investment management strategy, the implementation of which is subject to a number of constraints, may not produce the intended results.

Market Risk. The Fund could lose money due to short-term market movements and over longer periods during market downturns. Securities may decline in value due to factors affecting securities markets generally or particular industries represented in the markets. The value of a security may decline due to general market conditions, economic trends or events that are not specifically related to the issuer of the security or to factors that affect a particular industry or industries. During a general downturn in the securities markets, multiple asset classes may be negatively affected.

Market Trading Risk

Absence of Active Market. Although shares of the Fund are listed for trading on one or more stock exchanges, there can be no assurance that an active trading market for such shares will develop or be maintained.

Risk of Secondary Listings. The Fund’s shares may be listed or traded on U.S. and non-U.S. stock exchanges other than the U.S. stock exchange where the Fund’s primary listing is maintained. There can be no assurance that the Fund’s shares will continue to

trade on any such stock exchange or in any market or that the Fund’s shares will continue to meet the requirements for listing or trading on any exchange or in any market. The Fund’s shares may be less actively traded in certain markets than others, and investors are subject to the execution and settlement risks and market standards of the market where they or their broker direct their trades for execution. Certain information available to investors who trade Fund shares on a U.S. stock exchange during regular U.S. market hours may not be available to investors who trade in other markets, which may result in secondary market prices in such markets being less efficient.

Secondary Market Trading Risk. Shares of the Fund may trade in the secondary market at times when the Fund does not accept orders to purchase or redeem shares. At such times, shares may trade in the secondary market with more significant premiums or discounts than might be experienced at times when the Fund accepts purchase and redemption orders.

Secondary market trading in Fund shares may be halted by a stock exchange because of market conditions or other reasons. In addition, trading in Fund shares on a stock exchange or in any market may be subject to trading halts caused by extraordinary market volatility pursuant to “circuit breaker” rules on the stock exchange or market. There can be no assurance that the requirements necessary to maintain the listing or trading of Fund shares will continue to be met or will remain unchanged.

Shares of the Fund May Trade at Prices Other Than NAV. Shares of the Fund trade on stock exchanges at prices at, above or below their most recent NAV. The NAV of the Fund is calculated at the end of each business day and fluctuates with changes in the market value of the Fund’s holdings since the most recent calculation. The trading prices of the Fund’s shares fluctuate continuously throughout trading hours based on market supply and demand rather than NAV. The trading prices of the Fund’s shares may deviate significantly from NAV during periods of market volatility. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV. However, because shares can be created and redeemed in Creation Units at NAV (unlike shares of many closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their NAVs), BFA believes that large discounts or premiums to the NAV of the Fund are not likely to be sustained over the long-term. While the creation/redemption feature is designed to make it likely that the Fund’s shares normally will trade on stock exchanges at prices close to the Fund’s next calculated NAV, exchange prices are not expected to correlate exactly with the Fund’s NAV due to timing reasons as well as market supply and demand factors. In addition, disruptions to creations and redemptions or extreme market volatility may result in trading prices for shares of the Fund that differ significantly from its NAV.

Costs of Buying or Selling Fund Shares. Buying or selling Fund shares on an exchange involves two types of costs that apply to all securities transactions. When buying or selling shares of the Fund through a broker, you will likely incur a brokerage commission or other charges imposed by brokers as determined by that broker. In addition, you may incur the cost of the “spread” – that is, the difference between what investors are willing to pay for Fund shares (the “bid” price) and the price at which they

are willing to sell Fund shares (the “ask” price). Because of the costs inherent in buying or selling Fund shares, frequent trading may detract significantly from investment results and an investment in Fund shares may not be advisable for investors who anticipate regularly making small investments.

Non-Diversification Risk. The Fund is classified as “non-diversified.” This means that the Fund may invest a large percentage of its assets in securities issued by or representing a small number of issuers. As a result, the Fund may be more susceptible to the risks associated with these particular issuers, or to a single economic, political or regulatory occurrence affecting these issuers.

Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers are subject to all of the risks of investing in the markets where such issuers are located, including heightened risks of inflation or nationalization and market fluctuations caused by economic and political developments. As a result of investing in non-U.S. securities, the Fund may be subject to increased risk of loss caused by any of the factors listed below:

  • Lower levels of liquidity and market efficiency;
  • Greater securities price volatility;
  • Exchange rate fluctuations and exchange controls;
  • Less availability of public information about issuers;
  • Limitations on foreign ownership of securities;
  • Imposition of withholding or other taxes;
  • Imposition of restrictions on the expatriation of the funds or other assets of the Fund;
  • Higher transaction and custody costs and delays in settlement procedures;
  • Difficulties in enforcing contractual obligations;
  • Lower levels of regulation of the securities market;
  • Weaker accounting, disclosure and reporting requirements; and
  • Legal principles related to corporate governance, directors’ fiduciary duties and liabilities and stockholders’ rights in markets in which the Fund invests may differ and/or may not be as extensive or protective as those that apply in the United States.

Passive Investment Risk. The Fund is not actively managed and may be affected by a general decline in market segments related to the Underlying Index. The Fund invests in securities included in, or representative of, the Underlying Index regardless of their investment merits. BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

Privatization Risk. Some countries in which the Fund invests have begun a process of privatizing certain entities and industries. In some instances, investors in newly privatized entities have suffered losses due to the inability of the newly privatized entities to adjust quickly to a competitive environment or changing regulatory and legal standards or, in some cases, due to re-nationalization of such privatized entities. There is no assurance that such losses will not recur.

Reliance on Trading Partners Risk. The economies of many Asian countries are dependent on commodity prices and trade with the economies of Asia, Europe and the United States as key trading partners. Reduction in spending on products and services of these markets by any of their key trading partners, institution of tariffs or other trade barriers or a slowdown in the economies of any of their key trading partners may cause an adverse impact on the economies of the markets in which the Fund invests.

Risk of Investing in China. The Chinese economy is subject to a considerable degree of economic, political and social instability:

Political and Social Risk. The Chinese government is authoritarian and has periodically used force to suppress civil dissent. Disparities of wealth and the pace of economic liberalization may lead to social turmoil, violence and labor unrest. In addition, China continues to experience disagreements related to integration with Hong Kong and religious and nationalist disputes in Tibet and Xinjiang. There is also a greater risk involved in currency fluctuations, currency convertibility, interest rate fluctuations and higher rates of inflation as a result of internal social unrest or conflicts with other countries. Unanticipated political or social developments may result in sudden and significant investment losses. China’s growing income inequality and worsening environmental conditions also are factors that may affect the Chinese economy.

Government Control and Regulations. The Chinese government has implemented significant economic reforms in order to liberalize trade policy, promote foreign investment in the economy, reduce government control of the economy and develop market mechanisms. There can be no assurance these reforms will continue or that they will be effective. Despite recent reform and privatizations, significant regulation of investment and industry is still pervasive and the Chinese government may restrict foreign ownership of Chinese corporations and repatriation of assets. Chinese markets generally continue to experience inefficiency, volatility and pricing anomalies that may be connected to governmental influence, a lack of publicly-available information and/or political and social instability.

Economic Risk. The Chinese economy has grown rapidly during the past several years and there is no assurance that this growth rate will be maintained. China may experience substantial rates of inflation or economic recessions, causing a negative effect on the economy and securities market. Delays in enterprise restructuring, slow development of well-functioning financial markets and widespread corruption have also hindered performance of the Chinese economy. China continues to receive substantial pressure from trading partners to liberalize official currency exchange rates.

Expropriation Risk. The Chinese government maintains a major role in economic policymaking and investing in China involves risk of loss due to expropriation, nationalization, or confiscation of assets and property or the imposition of restrictions on foreign investments and on repatriation of capital invested.

Hong Kong Political Risk. Hong Kong reverted to Chinese sovereignty on July 1, 1997 as a Special Administrative Region (SAR) of the People’s Republic of China (“PRC”) under the principle of “one country, two systems.” Although China is obligated to maintain the current capitalist economic and social system of Hong Kong through June 30,

2047, the continuation of economic and social freedoms enjoyed in Hong Kong is dependent on the government of China. Any attempt by China to tighten its control over Hong Kong’s political, economic, legal or social policies may result in an adverse effect on Hong Kong’s markets. In addition, the Hong Kong dollar trades at a fixed exchange rate in relation to (or, is “pegged” to) the U.S. dollar, which has contributed to the growth and stability of the Hong Kong economy. However, it is uncertain how long the currency peg will continue or what effect the establishment of an alternative exchange rate system would have on the Hong Kong economy. Because the Fund’s NAV is denominated in U.S. dollars, the establishment of an alternative exchange rate system could result in a decline in the Fund’s NAV.

Risk of Investing in India. India is an emerging market and exhibits significantly greater market volatility from time to time in comparison to more developed markets. Political and legal uncertainty, greater government control over the economy, currency fluctuations or blockage, and the risk of nationalization or expropriation of assets may offer higher potential for losses.

Moreover, governmental actions can have a significant effect on the economic conditions in India, which could adversely affect the value and liquidity of the Fund’s investments. The securities markets in India are comparatively underdeveloped, and stockbrokers and other intermediaries may not perform as well as their counterparts in the United States and other more developed securities markets. The limited liquidity of the Indian securities markets may also affect the Fund’s ability to acquire or dispose of securities at the price and time that it desires.

Global factors and foreign actions may inhibit the flow of foreign capital on which India is dependent to sustain its growth. In addition, the Reserve Bank of India (“RBI”) has imposed limits on foreign ownership of Indian securities, which may decrease the liquidity of the Fund’s portfolio and result in extreme volatility in the prices of Indian securities. These factors, coupled with the lack of extensive accounting, auditing and financial reporting standards and practices, as compared to the United States, may increase the Fund’s risk of loss.

Further, certain Indian regulatory approvals, including approvals from the Securities and Exchange Board of India (“SEBI”), the central government and the tax authorities (to the extent that tax benefits need to be utilized), may be required before the Fund can make investments in the securities of Indian companies.

Risk of Investing in South Korea. Investment in South Korean issuers involves risks that are specific to South Korea, including legal, regulatory, political, currency, security and economic risks. Substantial political tensions exist between North Korea and South Korea and recently, these political tensions have escalated. The outbreak of hostilities between the two nations, or even the threat of an outbreak of hostilities will likely adversely impact the South Korean economy. In addition, South Korea’s economic growth potential has recently been on a decline, mainly because of a rapidly aging population and structural problems.

Securities Lending Risk. The Fund may engage in securities lending. Securities lending involves the risk that the Fund may lose money because the borrower of the Fund’s loaned securities fails to return the securities in a timely manner or at all. The

Fund could also lose money in the event of a decline in the value of the collateral provided for the loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Security Risk. Some geographic areas in which the Fund invests have experienced acts of terrorism or strained international relations due to territorial disputes, historical animosities or other defense concerns. These situations may cause uncertainty in the markets of these geographic areas and may adversely affect the performance of their economies.

Tracking Error Risk. Imperfect correlation between the Fund’s portfolio securities and those in the Underlying Index, rounding of prices, changes to the Underlying Index and regulatory requirements may cause tracking error, which is the divergence of the Fund’s performance from that of the Underlying Index. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Underlying Index does not. Because the Fund employs a representative sampling strategy, the Fund may experience tracking error to a greater extent than a fund that seeks to replicate an index. BFA EXPECTS THAT THE FUND MAY EXPERIENCE HIGHER TRACKING ERROR THAN IS TYPICAL FOR SIMILAR INDEX ETFS.

Treaty/Tax Risk. The Fund operates, in part, through the Subsidiary, which in turn invests in securities of Indian issuers. The Subsidiary in Mauritius should be eligible to take advantage of the benefits of the DTAA for so long as it holds a tax residency certificate in Mauritius. Numerous investors have relied on the benefits of the DTAA to invest in India through Mauritius in the past. However, in the past 10-15 years a number of parties have challenged the DTAA or the interpretation of the DTAA. Circular 789, issued on April 13, 2000 by the Indian Central Board of Direct Taxes, clarifies that whenever the Mauritius revenue authorities have issued a certificate of tax residence, such certificate would constitute sufficient evidence for accepting the status of residence of Mauritius tax residents for purposes of applying the provisions of the DTAA. The Supreme Court of India in 2003 subsequently held and declared Circular 789 to be valid following litigation regarding Circular 789. As of the date of this Prospectus, Circular 789 is still valid and in force.

However, recently issued rulings suggest that the Indian tax administration’s analysis may have changed, and that the tax authorities may now focus on a number of factors when assessing whether a foreign entity is eligible for the benefit of the provisions of a tax treaty, including, among others, the place of management of the foreign resident company and the level of substance in the jurisdiction in which it is incorporated. In addition, both the Indian tax administration and Indian courts seem now to be very aggressive towards structures involving offshore funds investing directly or indirectly in India, in particular those from Mauritius.

Recently, there have been reports in the Indian press that the Indian government is seeking to renegotiate the DTAA. Members of the Indian Parliament have also proposed legislation that could eliminate the benefits of the DTAA. No assurance can be given that the terms of the DTAA will not be renegotiated or subject to a different interpretation in the future. Any change in the provisions of the DTAA or in its

applicability to the Subsidiary could result in the imposition of withholding and capital gains taxes and other taxes on the Subsidiary by tax authorities in India. This could significantly reduce the return to the Fund on its investments and the return received by the Fund’s shareholders.

Indian Tax Risk. The Direct Taxes Code, 2010 (“New Taxes Code”) was recently tabled before the Lok Sabha (the lower house of the Indian Parliament), which, if enacted, will replace the existing Income Tax Act, 1961 (“Income Tax Act”) with effect from April 1, 2012. Further, provisions of the New Taxes Code, if enacted, could change the manner in which the Subsidiary is currently taxed in India, and could adversely impact the returns to the Fund/Subsidiary and its shareholders. In addition, the New Taxes Code may not be enacted in its current draft form. Hence, no assurance can be given that the interpretations described in this discussion will remain in effect. Any changes could also be applied retroactively, including to transactions entered into before the effective date of the New Taxes Code. Investors are urged to consult their own tax advisers with respect to their own tax situations and the tax consequences of an investment in the Fund. For a brief overview of matters in relation to Indian taxation, please see The Direct Taxes Code, 2010 section of this Prospectus.

Valuation Risk. Because non-U.S. exchanges may be open on days when the Fund does not price its shares, the value of the securities in the Fund’s portfolio may change on days when shareholders will not be able to purchase or sell the Fund’s shares. In addition, for purposes of calculating the Fund’s NAV, the value of assets denominated in non-U.S. currencies is converted into U.S. dollars using exchange rates deemed appropriate by BFA. This conversion may result in a difference between the prices used to calculate the Fund’s NAV and the prices used by the Underlying Index, which, in turn, could result in a difference between the Fund’s performance and the performance of the Underlying Index.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

Consumer Staples Sector Risk. The Fund invests in companies in the consumer staples sector. The consumer staples sector may be affected by the permissibility of using various food additives and production methods, marketing campaigns and other factors affecting consumer demand. Tobacco companies, in particular, may be adversely affected by new laws, regulations and litigation. The consumer staples sector may also be adversely affected by changes or trends in commodity prices, which may be influenced or characterized by unpredictable factors.

Energy Sector Risk. The energy sector is cyclical and highly dependent on commodities prices. The market values of companies in the energy sector are strongly affected by the levels and volatility of global energy prices, energy supply and demand, capital expenditures on exploration and production, energy conservation efforts, exchange rates and technological advances, among other factors. Companies in this sector may be subject to substantial government regulation and contractual fixed pricing, which may increase the cost of business and limit these companies’ earnings. A significant portion of their revenues depends on a relatively small number of

customers, including governmental entities and utilities. As a result, governmental budget constraints may have a material adverse effect on the stock prices of companies in this industry. Energy companies may also operate in countries with less developed regulatory regimes or a history of expropriation, nationalization or other adverse policies. Energy companies also face a significant risk of civil liability from accidents resulting in injury or loss of life or property, pollution or other environmental mishaps, equipment malfunctions or mishandling of materials and a risk of loss from terrorism and natural disasters. Any such event could have serious consequences for the general population of the area affected and result in a material adverse impact on the Fund’s portfolio and the performance of the Fund. Energy companies can be significantly affected by the supply of, and demand for, specific products (e.g., oil and natural gas) and services, exploration and production spending, government regulation, world events and general economic conditions.

Materials Sector Risk. Companies in the materials sector could be adversely affected by commodity price volatility, exchange rates, import controls, increased competition, depletion of resources, technical progress, labor relations, exchange rates and government regulations, among other factors. Also, companies in the materials sector are at risk of liability for environmental damage and product liability claims. Production of materials may exceed demand as a result of market imbalances or economic downturns, leading to poor investment returns.

Telecommunications Sector Risk. The telecommunications sector is subject to extensive government regulation. The costs of complying with governmental regulations, delays or failure to receive required regulatory approvals, or the enactment of new adverse regulatory requirements may negatively affect the business of the telecommunications companies. Government actions around the world, specifically in the area of pre-marketing clearance of products and prices, can be arbitrary and unpredictable. Companies in the telecommunications sector may encounter distressed cash flows due to the need to commit substantial capital to meet increasing competition, particularly in formulating new products and services using new technology. Technological innovations may make the products and services of telecommunications companies obsolete.

Portfolio Holdings Information

A description of the Trust’s policies and procedures with respect to the disclosure of the Fund’s portfolio securities is available in the Fund’s Statement of Additional Information (“SAI”). The top holdings of the Fund can be found at www.iShares.com. Fund fact sheets provide information regarding the Fund’s top holdings and may be requested by calling 1-800-iShares (1-800-474-2737).

Management

Investment Adviser. As investment adviser, BFA has overall responsibility for the general management and administration of the Trust. BFA provides an investment program for the Fund and manages the investment of the Fund’s assets. In managing the Fund, BFA may draw upon the research and expertise of its asset management affiliates with respect to certain portfolio securities. In seeking to achieve the Fund’s

investment objective, BFA uses teams of portfolio managers, investment strategists and other investment specialists. This team approach brings together many disciplines and leverages BFA’s extensive resources.

Pursuant to the Investment Advisory Agreement between BFA and the Trust (entered into on behalf of the Fund), BFA is responsible for substantially all expenses of the Fund, except interest expenses, taxes, brokerage expenses, future distribution fees or expenses and extraordinary expenses.

For its investment advisory services to the Fund, BFA is entitled to receive a management fee from the Fund corresponding to the Fund’s allocable portion of an aggregate management fee based on the aggregate average daily net assets of the following iShares funds: iShares MSCI All Country Asia ex Japan Index Fund, iShares MSCI BRIC Index Fund, iShares MSCI Emerging Markets Eastern Europe Index Fund, iShares MSCI Emerging Markets Financials Sector Index Fund, iShares MSCI Emerging Markets Index Fund, iShares MSCI Emerging Markets Materials Sector Index Fund, iShares MSCI Emerging Markets Minimum Volatility Index Fund and iShares MSCI Emerging Markets Small Cap Index Fund. The aggregate management fee is calculated as follows: 0.75% per annum of the aggregate net assets less than or equal to $14.0 billion, plus 0.68% per annum of the aggregate net assets over $14.0 billion, up to and including $28.0 billion, plus 0.61% per annum of the aggregate net assets over $28.0 billion, up to and including $42.0 billion, plus 0.56% per annum of the aggregate net assets over $42.0 billion, up to and including $56.0 billion, plus 0.50% per annum of the aggregate net assets over $56.0 billion, up to and including $70.0 billion, plus 0.45% per annum of the aggregate net assets over $70.0 billion, up to and including $84.0 billion, plus 0.40% per annum of the aggregate net assets in excess of $84.0 billion. As calculated on July 31, 2011, for its investment advisory services to the Fund, BFA is entitled to receive a management fee from the Fund, based on a percentage of the Fund’s average daily net assets, at an annual rate of 0.67%.

BFA is located at 400 Howard Street, San Francisco, CA 94105. It is a wholly owned subsidiary of BTC, which in turn is indirectly wholly-owned by BlackRock, Inc. (“BlackRock”). As of September 30, 2011, BTC and its affiliates, including BFA and BlackRock, provided investment advisory services for assets in excess of $3.35 trillion. BFA, BTC, BlackRock Execution Services, BlackRock and their affiliates deal, trade and invest for their own accounts in the types of securities in which the Fund may also invest.

A discussion regarding the basis for the Trust’s Board of Trustees’ (the “Board”) approval of the Investment Advisory Agreement with BFA is available in the Fund’s annual report for the period ended July 31.

Portfolio Managers. Christopher Bliss, Rene Casis, Diane Hsiung and Greg Savage are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager is responsible for various functions related to portfolio management, including, but not limited to, investing cash inflows, coordinating with members of his or her portfolio management team to focus on certain asset classes, implementing investment strategy, researching and reviewing investment strategy and overseeing members of his or her portfolio management team that have more limited responsibilities.

Christopher Bliss has been employed by BFA (formerly, Barclays Global Fund Advisors (“BGFA”)) and BTC (formerly, Barclays Global Investors, N.A. (“BGI”)) as a senior portfolio manager since 2005. Prior to that, Mr. Bliss was a portfolio manager from 2004 to 2005 for BGFA and BGI. Mr. Bliss has been a Portfolio Manager of the Fund since 2011.

Rene Casis has been employed by BFA and BTC as a senior portfolio manager since 2009. From 2005 to 2009, Mr. Casis was a trader at Barclays Capital. Prior to that, Mr. Casis was a portfolio manager from 2000 to 2005 for BGFA and BGI. Mr. Casis has been a Portfolio Manager of the Fund since 2010.

Diane Hsiung has been employed by BFA and BTC as a senior portfolio manager since 2007. Prior to that, Ms. Hsiung was a portfolio manager from 2002 to 2006 for BGFA and BGI. Ms. Hsiung has been a Portfolio Manager of the Fund since 2008.

Greg Savage has been employed by BFA and BTC as a senior portfolio manager since 2006. Prior to that, Mr. Savage was a portfolio manager from 2001 to 2006 for BGFA and BGI. Mr. Savage has been a Portfolio Manager of the Fund since 2008.

The Fund’s SAI provides additional information about the Portfolio Managers’ compensation, other accounts managed by the Portfolio Managers and the Portfolio Managers’ ownership (if any) of shares in the Fund.

Administrator, Custodian and Transfer Agent. State Street Bank and Trust Company (“State Street”) is the administrator, custodian and transfer agent for the Fund.

Conflicts of Interest. BFA wants you to know that there are certain entities with which BFA has relationships that may give rise to conflicts of interest, or the appearance of conflicts of interest. These entities include the following: BFA’s affiliates (including BlackRock and The PNC Financial Services Group, Inc., and each of their affiliates, directors, partners, trustees, managing members, officers and employees (collectively, the “Affiliates”)) and BlackRock’s significant shareholder, Barclays Bank PLC and its affiliates, including Barclays PLC (each, an “Entity” and together, the “Entities”).

The activities of BFA, the Affiliates and the Entities in the management of, or their interest in, their own accounts and other accounts they manage, may present conflicts of interest that could disadvantage the Fund and its shareholders. BFA and its Affiliates or the Entities provide investment management services to other funds and discretionary managed accounts that may follow an investment program similar to that of the Fund. BFA, its Affiliates and the Entities are involved worldwide with a broad spectrum of financial services and asset management activities and may engage in the ordinary course of business in activities in which their interests or the interests of their clients may conflict with those of the Fund. BFA, one or more of the Affiliates or the Entities acts, or may act, as an investor, investment banker, research provider, investment manager, financier, underwriter, advisor, market maker, trader, prime broker, lender, agent or principal, and have other direct and indirect interests, in securities, currencies and other instruments in which the Fund may directly or indirectly invest. Thus, it is likely that the Fund will have multiple business relationships with and will invest in, engage in transactions with, make voting decisions with respect

to, or obtain services from, entities for which BFA, an Affiliate or an Entity performs or seeks to perform investment banking or other services.

BFA or one or more Affiliates or Entities may engage in proprietary trading and advise accounts and funds that have investment objectives similar to those of the Fund and/or that engage in and compete for transactions in the same types of securities, currencies and other instruments as the Fund, including in securities issued by other open-end and closed-end investment management companies, including investment companies that are affiliated with the Fund and BFA, to the extent permitted under the Investment Company Act of 1940, as amended (the “1940 Act”). The trading activities of BFA, these Affiliates and Entities are carried out without reference to positions held directly or indirectly by the Fund and may result in BFA, an Affiliate or an Entity having positions that are adverse to those of the Fund.

No Affiliate or Entity is under any obligation to share any investment opportunity, idea or strategy with the Fund. As a result, an Affiliate or an Entity may compete with the Fund for appropriate investment opportunities. As a result of this and several other factors, the results of the Fund’s investment activities may differ from those of an Affiliate or an Entity and of other accounts managed by an Affiliate or an Entity, and it is possible that the Fund could sustain losses during periods in which one or more Affiliates or Entities and other accounts achieve profits on their trading for proprietary or other accounts. The opposite result is also possible.

The Fund may, from time to time, enter into transactions in which BFA or an Affiliate’s or an Entity’s clients have an interest adverse to the Fund. Furthermore, transactions undertaken by Affiliate-advised clients may adversely impact the Fund. Transactions by one or more Affiliate- or Entity-advised clients or BFA may have the effect of diluting or otherwise disadvantaging the values, prices or investment strategies of the Fund.

An Entity may maintain securities indices as part of its product offerings. Index-based funds seek to track the performance of securities indices and may use the name of the index in the fund name. Index providers, including the Entities, may be paid licensing fees for use of their indices or index names. Entities will not be obligated to license their indices to BFA and its Affiliates, and BFA and its Affiliates will not be assured that the terms of any index licensing agreement with the Entities will be as favorable as those terms offered to other index licensees.

The Fund’s activities may be limited because of regulatory restrictions applicable to one or more Affiliates or Entities, and/or their internal policies designed to comply with such restrictions. In addition, the Fund may invest in securities of companies with which an Affiliate or an Entity has or is trying to develop investment banking relationships or in which an Affiliate or an Entity has significant debt or equity investments. The Fund also may invest in securities of companies for which an Affiliate or an Entity provides or may some day provide research coverage. An Affiliate or an Entity may have business relationships with and purchase or distribute or sell services or products from or to distributors, consultants or others who recommend the Fund or who engage in transactions with or for the Fund, and may receive compensation for such services. The Fund may also make brokerage and other payments to Affiliates or Entities in connection with the Fund’s portfolio investment transactions.

Pursuant to a securities lending program approved by the Board, the Fund has retained an Affiliate of BFA to serve as the securities lending agent for the Fund to the extent that the Fund participates in the securities lending program. For these services, the lending agent may receive a fee from the Fund, including a fee based on the returns earned on the Fund’s investment of the cash received as collateral for any loaned securities. In addition, one or more Affiliates may be among the entities to which the Fund may lend its portfolio securities under the securities lending program.

The activities of BFA, the Affiliates or Entities may give rise to other conflicts of interest that could disadvantage the Fund and its shareholders. BFA has adopted policies and procedures designed to address these potential conflicts of interest. See the Fund’s SAI for further information.

Shareholder Information

Additional shareholder information, including how to buy and sell shares of the Fund, is available free of charge by calling toll-free: 1-800-iShares (1-800-474-2737) or visiting our website at www.iShares.com.

Buying and Selling Shares. Shares of the Fund may be acquired or redeemed directly from the Fund only in Creation Units or multiples thereof, as discussed in the Creations and Redemptions section of this Prospectus. Only an Authorized Participant (as defined in the Creations and Redemptions section) may engage in creation or redemption transactions directly with the Fund. Once created, shares of the Fund generally trade in the secondary market in amounts less than a Creation Unit.

Shares of the Fund are listed on a national securities exchange for trading during the trading day. Shares can be bought and sold throughout the trading day like shares of other publicly-traded companies. The Trust does not impose any minimum investment for shares of the Fund purchased on an exchange. The Fund’s shares trade under the trading symbol “AAXJ.”

Buying or selling Fund shares on an exchange involves two types of costs that may apply to all securities transactions. When buying or selling shares of the Fund through a broker, you will likely incur a brokerage commission or other charges determined by your broker. The commission is frequently a fixed amount and may be a significant proportional cost for investors seeking to buy or sell small amounts of shares. In addition, you may incur the cost of the “spread” – that is, any difference between the bid price and the ask price. The spread varies over time for shares of the Fund based on its trading volume and market liquidity, and is generally lower if the Fund has a lot of trading volume and market liquidity, and higher if the Fund has little trading volume and market liquidity.

The Board has adopted a policy of not monitoring for frequent purchases and redemptions of Fund shares (“frequent trading”) that appear to attempt to take advantage of a potential arbitrage opportunity presented by a lag between a change in the value of the Fund’s portfolio securities after the close of the primary markets for the Fund’s portfolio securities and the reflection of that change in the Fund’s NAV (“market timing”), because the Fund generally sells and redeems its shares directly through transactions that are in-kind and/or for cash, subject to the conditions

described below under Creations and Redemptions. The Board has not adopted a policy of monitoring for other frequent trading activity because shares of the Fund are listed for trading on a national securities exchange.

The national securities exchange on which the Fund’s shares are listed is open for trading Monday through Friday and is closed on weekends and the following holidays: New Year’s Day, Martin Luther King, Jr. Day, Presidents’ Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day. The Fund’s primary listing exchange is NASDAQ.

Section 12(d)(1) of the 1940 Act restricts investments by investment companies in the securities of other investment companies. Registered investment companies are permitted to invest in the Fund beyond the limits set forth in Section 12(d)(1), subject to certain terms and conditions set forth in SEC rules or in an SEC exemptive order issued to the Trust. In order for a registered investment company to invest in shares of the Fund beyond the limitations of Section 12(d)(1) pursuant to the exemptive relief obtained by the Trust, the registered investment company must enter into an agreement with the Trust.

Book Entry. Shares of the Fund are held in book-entry form, which means that no stock certificates are issued. The Depository Trust Company (“DTC”) or its nominee is the record owner of all outstanding shares of the Fund and is recognized as the owner of all shares for all purposes.

Investors owning shares of the Fund are beneficial owners as shown on the records of DTC or its participants. DTC serves as the securities depository for shares of the Fund. DTC participants include securities brokers and dealers, banks, trust companies, clearing corporations and other institutions that directly or indirectly maintain a custodial relationship with DTC. As a beneficial owner of shares, you are not entitled to receive physical delivery of stock certificates or to have shares registered in your name, and you are not considered a registered owner of shares. Therefore, to exercise any right as an owner of shares, you must rely upon the procedures of DTC and its participants. These procedures are the same as those that apply to any other securities that you hold in book-entry or “street name” form.

Share Prices. The trading prices of the Fund’s shares in the secondary market generally differ from the Fund’s daily NAV and are affected by market forces such as supply and demand, economic conditions and other factors. Information regarding the intraday value of shares of the Fund, also known as the “indicative optimized portfolio value” (“IOPV”), is disseminated every 15 seconds throughout the trading day by the national securities exchange on which the Fund’s shares are listed or by market data vendors or other information providers. The IOPV is based on the current market value of the securities and/or cash required to be deposited in exchange for a Creation Unit. The IOPV does not necessarily reflect the precise composition of the current portfolio of securities held by the Fund at a particular point in time or the best possible valuation of the current portfolio. Therefore, the IOPV should not be viewed as a “real-time” update of the Fund’s NAV, which is computed only once a day. The IOPV is generally determined by using both current market quotations and/or price quotations obtained from broker-dealers that may trade in the portfolio securities held by the Fund. The quotations of certain Fund holdings may not be updated during U.S. trading hours if

such holdings do not trade in the United States. The Fund is not involved in, or responsible for, the calculation or dissemination of the IOPV and makes no representation or warranty as to its accuracy.

Determination of Net Asset Value. The NAV of the Fund normally is determined once daily Monday through Friday, generally as of the regularly scheduled close of business of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m., Eastern time) on each day that the NYSE is open for trading, based on prices at the time of closing provided that (a) any Fund assets or liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers (as detailed below) and (b) U.S. fixed income assets may be valued as of the announced closing time for trading in fixed income instruments in a particular market or exchange. The NAV of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets held by the Fund, and its liabilities, are determined pursuant to valuation policies and procedures approved by the Board. The Fund’s assets and liabilities are valued primarily on the basis of market quotations.

Equity investments are valued at market value, which is generally determined using the last reported official closing price or last trading price on the exchange or market on which the security is primarily traded at the time of valuation.

The Fund invests in foreign securities. Foreign currency exchange rates are generally determined as of 4:00 p.m., London time. Foreign securities owned by the Fund may trade on weekends or other days when the Fund does not price its shares. As a result, the Fund’s NAV may change on days when Authorized Participants will not be able to purchase or redeem Fund shares.

Generally, trading in foreign securities, U.S. government securities, money market instruments and certain fixed-income securities is substantially completed each day at various times prior to the close of business on the NYSE. The values of such securities used in computing the NAV of the Fund are determined as of such times.

When market quotations are not readily available or are believed by BFA to be unreliable, the Fund’s investments are valued at fair value. Fair value determinations are made by BFA in accordance with policies and procedures approved by the Fund’s Board. BFA may conclude that a market quotation is not readily available or is unreliable if a security or other asset or liability does not have a price source due to its lack of liquidity, if a market quotation differs significantly from recent price quotations or otherwise no longer appears to reflect fair value, where the security or other asset or liability is thinly traded, or where there is a significant event subsequent to the most recent market quotation. A “significant event” is an event that, in the judgment of BFA, is likely to cause a material change to the closing market price of the asset or liability held by the Fund. Foreign securities whose values are affected by volatility that occurs in U.S. markets on a trading day after the close of foreign securities markets may be fair valued.

Fair value represents a good faith approximation of the value of an asset or liability. The fair value of an asset or liability held by the Fund is the amount the Fund might reasonably expect to receive from the current sale of that asset or the cost to extinguish that liability in an arm’s-length transaction. Valuing the Fund’s investments using fair value pricing will result in prices that may differ from current market valuations and that may not be the price at which those investments could have been sold during the period in which the particular fair values were used. Use of fair value prices and certain current market valuations could result in a difference between the prices used to calculate the Fund’s NAV and the prices used by the Underlying Index, which, in turn, could result in a difference between the Fund’s performance and the performance of the Underlying Index.

The value of assets or liabilities denominated in non-U.S. currencies will be converted into U.S. dollars using exchange rates deemed appropriate by BFA as investment adviser. Use of a rate different from the rate used by the Index Provider may adversely affect the Fund’s ability to track the Underlying Index.

Dividends and Distributions

General Policies. Dividends from net investment income, if any, generally are declared and paid semi-annually by the Fund. Distributions of net realized securities gains, if any, generally are declared and paid once a year, but the Trust may make distributions on a more frequent basis for the Fund. The Trust reserves the right to declare special distributions if, in its reasonable discretion, such action is necessary or advisable to preserve its status as a regulated investment company (“RIC”) or to avoid imposition of income or excise taxes on undistributed income or realized gains.

Dividends and other distributions on shares of the Fund are distributed on a pro rata basis to beneficial owners of such shares. Dividend payments are made through DTC participants and indirect participants to beneficial owners then of record with proceeds received from the Fund.

Dividend Reinvestment Service. No dividend reinvestment service is provided by the Trust. Broker-dealers may make available the DTC book-entry Dividend Reinvestment Service for use by beneficial owners of the Fund for reinvestment of their dividend distributions. Beneficial owners should contact their broker to determine the availability and costs of the service and the details of participation therein. Brokers may require beneficial owners to adhere to specific procedures and timetables. If this service is available and used, dividend distributions of both income and realized gains will be automatically reinvested in additional whole shares of the Fund purchased in the secondary market.

Taxes. As with any investment, you should consider how your investment in shares of the Fund will be taxed. The tax information in this Prospectus is provided as general information, based on current law. You should consult your own tax professional about the tax consequences of an investment in shares of the Fund.

Unless your investment in Fund shares is made through a tax-exempt entity or tax-deferred retirement account, such as an IRA, you need to be aware of the possible tax consequences when the Fund makes distributions or you sell Fund shares.

Taxes on Distributions. Distributions from the Fund’s net investment income (other than qualified dividend income), including distributions of income from securities lending and distributions out of the Fund’s net short-term capital gains, if any, are taxable to you as ordinary income. Distributions by the Fund of net long-term capital gains in excess of net short-term capital losses (capital gain dividends) are taxable to you as long-term capital gains, generally at a 15% tax rate (0% at certain income levels), regardless of how long you have held the Fund’s shares. Distributions by the Fund that qualify as qualified dividend income are taxable to you at long-term capital gain rates for taxable years beginning on or before December 31, 2012. The 15% and 0% tax rates expire for taxable years beginning after December 31, 2012. Maximum long-term capital gain income tax rates are scheduled to rise to 20% in 2013. Beginning in 2013, a 3.8% U.S. federal Medicare contribution tax will be imposed on “net investment income,” including interest, dividends, and capital gains, of U.S. individuals with income exceeding $200,000 (or $250,000 if married and filing jointly), and of estates and trusts.

Dividends will be qualified dividend income to you if they are attributable to qualified dividend income received by the Fund. Generally, qualified dividend income includes dividend income from taxable U.S. corporations and qualified non-U.S. corporations, provided that the Fund satisfies certain holding period requirements in respect of the stock of such corporations and has not hedged its position in the stock in certain ways. Substitute dividends received by the Fund with respect to dividends paid on securities lent out will not be qualified dividend income. For this purpose, a qualified non-U.S. corporation means any non-U.S. corporation that is eligible for benefits under a comprehensive income tax treaty with the United States, which includes an exchange of information program or if the stock with respect to which the dividend was paid is readily tradable on an established United States securities market. The term excludes a corporation that is a passive foreign investment company.

Dividends received by the Fund from a real estate investment trust (“REIT”) or another RIC generally are qualified dividend income only to the extent the dividend distributions are made out of qualified dividend income received by such REIT or RIC. It is expected that dividends received by the Fund from a REIT and distributed to a shareholder generally will be taxable to the shareholder as ordinary income.

For a dividend to be treated as qualified dividend income, the dividend must be received with respect to a share of stock held without being hedged by the Fund, and with respect to a share of the Fund held without being hedged by you, for 61 days during the 121-day period beginning at the date which is 60 days before the date on which such share becomes ex-dividend with respect to such dividend or, in the case of certain preferred stock, 91 days during the 181-day period beginning 90 days before such date.

If your Fund shares are loaned out pursuant to a securities lending arrangement, you may lose the ability to use foreign tax credits passed through by the Fund or to treat Fund dividends paid while the shares are held by the borrower as qualified dividend income.

In general, your distributions are subject to U.S. federal income tax for the year when they are paid. Certain distributions paid in January, however, may be treated as paid on December 31 of the prior year.

If the Fund’s distributions exceed current and accumulated earnings and profits, all or a portion of the distributions made in the taxable year may be recharacterized as a return of capital to shareholders. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and result in a higher capital gain or lower capital loss when those shares on which the distribution was received are sold. Once a shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain, if the shareholder holds shares of the Fund as capital assets.

If you are neither a resident nor a citizen of the United States or if you are a non-U.S. entity, the Fund’s ordinary income dividends (which include distributions of net short-term capital gains) will generally be subject to a 30% U.S. withholding tax, unless a lower treaty rate applies, provided that withholding tax will generally not apply to any gain or income realized by a non-U.S. shareholder in respect of any distributions of long-term capital gains or upon the sale or other disposition of shares of the Fund.

A 30% withholding tax will be imposed on dividends paid after December 31, 2013, and redemption proceeds paid after December 31, 2014, to (i) foreign financial institutions including non-U.S. investment funds unless they agree to collect and disclose to the Internal Revenue Service (“IRS”) information regarding their direct and indirect U.S. account holders and (ii) certain other foreign entities, unless they certify certain information regarding their direct and indirect U.S. owners. To avoid withholding, foreign financial institutions will need to enter into agreements with the IRS that state that they will provide the IRS information, including the name, address and taxpayer identification number of direct and indirect U.S. account holders, comply with due diligence procedures with respect to the identification of U.S. accounts, report to the IRS certain information with respect to U.S. accounts maintained, agree to withhold tax on certain payments made to non-compliant foreign financial institutions or to account holders who fail to provide the required information, and determine certain other information as to their account holders. Other foreign entities will need to provide the name, address, and taxpayer identification number of each substantial U.S. owner or certifications of no substantial U.S. ownership unless certain exceptions apply.

Dividends, interest and capital gains earned by the Fund with respect to non-U.S. securities may give rise to withholding and other taxes imposed by non-U.S. countries. Tax conventions between certain countries and the United States may reduce or eliminate such taxes. If more than 50% of the total assets of the Fund at the close of a year consists of non-U.S. stocks or securities, the Fund may “pass through” to you certain non-U.S. income taxes (including withholding taxes) paid by the Fund. This means that you would be considered to have received as an additional dividend your share of such non-U.S. taxes, but you may be entitled to either a corresponding tax deduction in calculating your taxable income, or, subject to certain limitations, a credit in calculating your U.S. federal income tax.

For purposes of foreign tax credits for U.S. shareholders of the Fund, foreign capital gains taxes may not produce associated foreign source income, thereby limiting a U.S. person’s ability to use such credits.

If you are a resident or a citizen of the United States, by law, back-up withholding will apply to your distributions and proceeds if you have not provided a taxpayer identification number or social security number and made other required certifications.

Taxes When Shares are Sold. Currently, any capital gain or loss realized upon a sale of Fund shares is generally treated as a long-term gain or loss if the shares have been held for more than one year. Any capital gain or loss realized upon a sale of Fund shares held for one year or less is generally treated as short-term gain or loss, except that any capital loss on the sale of shares held for six months or less is treated as long-term capital loss to the extent that capital gain dividends were paid with respect to such shares. Beginning in 2013, any such capital gains, including from sales of Fund shares or from capital gain dividends, will be included in “net investment income” for purposes of the 3.8% U.S. federal Medicare contribution tax mentioned above.

The foregoing discussion summarizes some of the consequences under current U.S. federal tax law of an investment in the Fund. It is not a substitute for personal tax advice. You may also be subject to state and local taxation on Fund distributions and sales of shares. Consult your personal tax adviser about the potential tax consequences of an investment in shares of the Fund under all applicable tax laws.

Chinese Tax Disclosure. Although the PRC’s enactment of the Enterprise Income Tax Law, effective January 1, 2008, provided a 10% withholding tax upon non-residents with respect to capital gains, significant uncertainties remain. Such uncertainties may result in capital gains imposed upon the Fund relative to companies headquartered, managed or listed in China. While the application and enforcement of this law to the Fund remains subject to clarification, to the extent that such taxes are imposed on any capital gains of the Fund relative to companies headquartered, managed or listed in China, the Fund’s NAV or returns may be adversely impacted.

Mauritius Tax Disclosure. The Fund conducts its investment activities in India through the Subsidiary and, as mentioned above, expects to obtain benefits under the DTAA. In order to be eligible to claim benefits under the DTAA, the Subsidiary must satisfy certain conditions, including the establishment and maintenance of a valid tax residence in Mauritius. The Subsidiary has obtained a certificate from the Mauritius authorities providing that it is a resident of Mauritius under the DTAA. The Fund expects the Subsidiary to maintain its Mauritius tax residency. The Subsidiary is subject to tax in Mauritius on its net income at the rate of 15%. However, a system of foreign tax credits effectively reduces the Mauritius income tax rate to a maximum of 3%. Further, the Subsidiary is not subject to capital gains tax in Mauritius nor is it subject to tax in Mauritius on any gains from the sale of securities. Any dividends paid by the Subsidiary to the Fund will also be exempt from tax in Mauritius. The foregoing is based upon current interpretation and practice and is subject to future changes in the tax laws of India or Mauritius and in the DTAA.

Indian Tax Disclosure. In the event the benefits under the DTAA are denied, the following rates of tax under the Indian Income Tax Act will be applicable (these rates are inclusive of applicable surcharges):

  • Dividend: Dividend income earned by the Subsidiary will not be subject to Indian tax. However, the Indian company declaring and paying such dividend would be subject to Dividend Distribution Tax at an effective rate of 16.223% on the amount of the dividend paid out.
  • Interest: Interest paid to the Subsidiary in respect of debt obligations of Indian issuers will be subject to Indian income tax. The tax rate in the case of a rupee-denominated debt obligation is 42.024%. In the case of a foreign-currency denominated debt obligation, the tax rate is 21.012%.
  • However, if the Subsidiary is registered as a sub-account with SEBI, interest from securities will be subject to tax at the rate of 21.012%.
  • Securities Transaction Tax: Transactions involving the purchase or sale of shares or any other security traded on a recognized Indian stock exchange are subject to Securities Transaction Tax (“STT”) at the rate of 0.125% on the transaction value of the purchase or sale. This STT is not applicable to primary issuances of equity shares by a company or to off-market transactions. Hence, STT will be payable if the Subsidiary buys or sells listed securities on a recognized Indian stock exchange.
  • Capital Gains: Capital gains will be taxed in the hands of the Subsidiary as follows: (i) short-term: 15.759% with respect to shares/debentures listed on any recognized stock exchange in India and where the sale is subject to STT and 42.024% in any other case, however, if the Subsidiary is registered as a sub-account with SEBI, this rate will be 31.518%, (ii) long-term: 0% with respect to shares listed on any recognized stock exchange in India and where the sale is subject to STT and 21.012% in any other case, however, if the Subsidiary is a SEBI registered sub-account, this rate will be 10.506%.

The Direct Taxes Code, 2010. The New Taxes Code has been tabled before the Lok Sabha (the lower house of the Indian Parliament), which, if enacted, will replace the existing Income Tax Act with effect from April 1, 2012. The New Taxes Code proposes several changes in the tax regime and administration thereof. There are several provisions therein which may severely impact the proposed structure, including the ones set out below which are based on the current draft of the New Taxes Code, which may not be enacted in the current draft form. They are as follows:

  • General anti-avoidance rules would apply (depending on rules yet to be framed by the Indian government) where foreign entities claiming the benefit of a tax treaty lack commercial substance in their country of incorporation. In cases where such anti-avoidance provisions are successfully invoked, the provisions of applicable tax treaties would be overridden. Other provisions would tax the income earned on the transfer of a foreign company’s shares outside of India if, at any time in the preceding 12-month period, 50% or more of the fair value of assets of the foreign company being transferred is represented, directly or indirectly, by underlying Indian assets.
  • Specific rules with respect to the documentation to be provided by a foreign entity which claims the benefit of a tax treaty into which India entered. In particular, the current draft of the New Taxes Code provides that a person shall be entitled to claim relief under the relevant tax treaty only upon receipt of a tax residency certificate in the “prescribed form.” Currently, there is no guidance on what the “prescribed form” is. This seems to suggest that a certificate of residence would be the minimum requirement for treaty entitlement.
  • The Subsidiary can be considered to be a resident in India if its place of effective management at any time in the year is in India. “Place of effective management” is defined in the New Taxes Code as (i) the place where the board of directors of the company or its executive directors, as the case may be, make their decisions; or (ii) in a case where the board of directors routinely approve the commercial and strategic decisions made by the executive directors or officers of the company, the place where such executive directors or officers of the company perform their functions.

Creations and Redemptions. Prior to trading in the secondary market, shares of the Fund are “created” at NAV by market makers, large investors and institutions only in block-size Creation Units of 100,000 shares or multiples thereof. Each “creator” or “Authorized Participant” enters into an authorized participant agreement with the Fund’s distributor, SEI Investments Distribution Co. (the “Distributor”). Only an Authorized Participant may create or redeem Creation Units directly with the Fund. A creation transaction, which is subject to acceptance by the transfer agent, generally takes place when an Authorized Participant deposits into the Fund a designated portfolio of securities and a specified amount of cash approximating the holdings of the Fund in exchange for a specified number of Creation Units. To the extent practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund.

Similarly, shares can be redeemed only in Creation Units, generally for a designated portfolio of securities and a specified amount of cash held by the Fund (“Fund Securities”). Except when aggregated in Creation Units, shares are not redeemable by the Fund. The prices at which creations and redemptions occur are based on the next calculation of NAV after an order is received in a form described in the authorized participant agreement.

The Fund intends to comply with the U.S. federal securities laws in accepting securities for deposit and satisfying redemptions with redemption securities by, among other means, assuring that any securities accepted for deposit and any securities used to satisfy redemption requests will be sold in transactions that would be exempt from registration under the Securities Act of 1933, as amended (the “1933 Act”). Further, an Authorized Participant that is not a “qualified institutional buyer,” as such term is defined under Rule 144A of the 1933 Act, will not be able to receive Fund Securities that are restricted securities eligible for resale under Rule 144A.

Creations and redemptions must be made through a firm that is either a member of the Continuous Net Settlement System of the National Securities Clearing Corporation or a DTC participant and has executed an agreement with the Distributor with respect to creations and redemptions of Creation Unit aggregations. Information about the

procedures regarding creation and redemption of Creation Units (including the cut-off times for receipt of creation and redemption orders) is included in the Fund’s SAI.

Because new shares may be created and issued on an ongoing basis, at any point during the life of the Fund a “distribution,” as such term is used in the 1933 Act, may be occurring. Broker-dealers and other persons are cautioned that some activities on their part may, depending on the circumstances, result in their being deemed participants in a distribution in a manner that could render them statutory underwriters and subject to the prospectus delivery and liability provisions of the 1933 Act. Any determination of whether one is an underwriter must take into account all the relevant facts and circumstances of each particular case.

Broker-dealers should also note that dealers who are not “underwriters” but are participating in a distribution (as contrasted to ordinary secondary transactions), and thus dealing with shares that are part of an “unsold allotment” within the meaning of Section 4(3)(C) of the 1933 Act, would be unable to take advantage of the prospectus delivery exemption provided by Section 4(3) of the 1933 Act. For delivery of prospectuses to exchange members, the prospectus delivery mechanism of Rule 153 under the 1933 Act is available only with respect to transactions on a national securities exchange.

Costs Associated with Creations and Redemptions. Authorized Participants are charged standard creation and redemption transaction fees to offset transfer and other transaction costs associated with the issuance and redemption of Creation Units. The standard creation and redemption transaction fees are set forth in the table below. The standard creation transaction fee is charged to the Authorized Participant on the day such Authorized Participant creates a Creation Unit, and is the same regardless of the number of Creation Units purchased by the Authorized Participant on the applicable business day. Similarly, the standard redemption transaction fee is charged to the Authorized Participant on the day such Authorized Participant redeems a Creation Unit, and is the same regardless of the number of Creation Units redeemed by the Authorized Participant on the applicable business day. In addition, if a purchase or redemption consists solely or partially of cash, the Authorized Participant may be required to cover certain brokerage, tax, foreign exchange, execution, market impact (including expenses associated with certain brokerage execution guarantees, as further described in the Fund’s SAI) and other costs and expenses related to the execution of trades resulting from the cash portion of such transactions. The Authorized Participants may also be required to pay an additional charge (up to the maximum amounts shown in the table below) to cover other costs related to a creation or redemption transaction. Investors who use the services of a broker or other financial intermediary may pay fees for such services.

The following table shows, as of September 30, 2011, the approximate value of one Creation Unit, standard fees and maximum additional charges for creations and redemptions (as described above):

Householding. Householding is an option available to certain Fund investors. Householding is a method of delivery, based on the preference of the individual investor, in which a single copy of certain shareholder documents can be delivered to investors who share the same address, even if their accounts are registered under different names. Please contact your broker-dealer if you are interested in enrolling in householding and receiving a single copy of prospectuses and other shareholder documents, or if you are currently enrolled in householding and wish to change your householding status.

Distribution

The Distributor distributes Creation Units for the Fund on an agency basis. The Distributor does not maintain a secondary market in shares of the Fund. The Distributor has no role in determining the policies of the Fund or the securities that are purchased or sold by the Fund. The Distributor’s principal address is One Freedom Valley Drive, Oaks, PA 19456.

In addition, BFA or its Affiliates make payments to broker-dealers, banks or other financial intermediaries (together, “intermediaries”) related to marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems, or their making shares of the Fund and certain other iShares funds available to their customers. Such payments, which may be significant to the intermediary, are not made by the Fund. Rather, such payments are made by BFA or its Affiliates from their own resources, which come directly or indirectly in part from fees paid by the iShares funds complex. Payments of this type are sometimes referred to as revenue-sharing payments. A financial intermediary may make decisions about which investment options it recommends or makes available, or the level of services provided, to its customers based on the revenue-sharing payments it is eligible to receive. Therefore, such payments to an intermediary create conflicts of interest between the intermediary and its customers and may cause the intermediary to recommend the Fund or other iShares funds over another investment. More information regarding these payments is contained in the Fund’s SAI. Please contact your salesperson or other investment professional for more information regarding any such payments his or her firm may receive from BFA or its Affiliates.

Financial Highlights

The financial highlights table is intended to help investors understand the Fund’s financial performance since inception. Certain information reflects financial results for a single share of the Fund. The total returns in the table represent the rate that an investor would have earned (or lost) on an investment in the Fund, assuming reinvestment of all dividends and distributions. This information has been audited by PricewaterhouseCoopers LLP, whose report is included, along with the Fund’s financial statements, in the Fund’s Annual Report (available upon request).

Supplemental Information

I. Premium/Discount Information

The table that follows presents information about the differences between the daily market price on secondary markets for shares of the Fund and the Fund’s NAV. NAV is the price at which the Fund issues and redeems shares. It is calculated in accordance with the standard formula for valuing mutual fund shares. The price used to calculate market returns (“Market Price”) of the Fund generally is determined using the midpoint between the highest bid and the lowest offer on the primary securities exchange on which shares of the Fund are listed for trading, as of the time that the Fund’s NAV is calculated. The Fund’s Market Price may be at, above or below its NAV. The NAV of the Fund will fluctuate with changes in the value of its portfolio holdings. The Market Price of the Fund will fluctuate in accordance with changes in its NAV, as well as market supply and demand.

Premiums or discounts are the differences (expressed as a percentage) between the NAV and Market Price of the Fund on a given day, generally at the time the NAV is calculated. A premium is the amount that the Fund is trading above the reported NAV, expressed as a percentage of the NAV. A discount is the amount that the Fund is trading below the reported NAV, expressed as a percentage of the NAV.

The following information shows the frequency of distributions of premiums and discounts for the Fund for each full calendar quarter of 2010 through September 30, 2011.

Each line in the table shows the number of trading days in which the Fund traded within the premium/discount range indicated. The number of trading days in each premium/discount range is also shown as a percentage of the total number of trading days in the period covered by the table. All data presented here represents past performance, which cannot be used to predict future results.

Greater than 2.0% 2 0.45%
Greater than 1.5% and Less than 2.0% 12 2.72

II. Total Return Information

The table that follows presents information about the total returns of the Fund and the Underlying Index as of the fiscal year ended July 31, 2011.

“Average Annual Total Returns” represent the average annual change in value of an investment over the periods indicated. “Cumulative Total Returns” represent the total change in value of an investment over the period indicated.

The Fund’s NAV is the value of one share of the Fund as calculated in accordance with the standard formula for valuing mutual fund shares. The NAV return is based on the NAV of the Fund and the market return is based on the Market Price of the Fund. Market Price is determined by using the midpoint between the highest bid and the lowest offer on the primary stock exchange on which shares of the Fund are listed for trading, as of the time that the Fund’s NAV is calculated. Since shares of the Fund did not trade in the secondary market until after the Fund’s inception, for the period from inception to the first day of secondary market trading in shares of the Fund, the NAV of the Fund is used as a proxy for the Market Price to calculate market returns. Market and NAV returns assume that dividends and capital gain distributions have been reinvested in the Fund at Market Price and NAV, respectively.

An index is a statistical composite that tracks a specified financial market or sector. Unlike the Fund, the Underlying Index does not actually hold a portfolio of securities and therefore does not incur the expenses incurred by the Fund. These expenses negatively impact the performance of the Fund. Also, market returns do not include brokerage commissions that may be payable on secondary market transactions. If brokerage commissions were included, market returns would be lower. The returns shown in the following table do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption or sale of Fund shares. The investment return and principal value of shares of the Fund will vary with changes in market conditions. Shares of the Fund may be worth more or less than their original cost when they are redeemed or sold in the market. The Fund’s past performance is no guarantee of future results.

Fund Overview

iSHARES® MSCI EAFE GROWTH INDEX FUND

Ticker: EFG Stock Exchange: NYSE Arca

Investment Objective

The iShares MSCI EAFE Growth Index Fund (the “Fund”) seeks investment results that correspond generally to the price and yield performance, before fees and expenses, of the MSCI EAFE® Growth Index (the “Underlying Index”).

Fees and Expenses

The following table describes the fees and expenses that you will incur if you own shares of the Fund. The investment advisory agreement between iShares Trust (the “Trust”) and BlackRock Fund Advisors (“BFA”) (the “Investment Advisory Agreement”) provides that BFA will pay all operating expenses of the Fund, except interest expenses, taxes, brokerage expenses, future distribution fees or expenses, and extraordinary expenses.

You may also incur usual and customary brokerage commissions when buying or selling shares of the Fund, which are not reflected in the example that follows:

Annual Fund Operating Expenses

percentage of the value of your investments)
Management
Fees

Other
Expenses
Total Annual
Fund
Operating
Expenses
0.40% None None 0.40%

Example. This Example is intended to help you compare the cost of owning shares of the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

1 Year
3 Years
5 Years
10 Years
$41 $128 $224 $505

Portfolio Turnover. The Fund may pay transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 27% of the average value of its portfolio.

Principal Investment Strategies

The Underlying Index is a subset of the MSCI EAFE® Index and constituents of the Underlying Index include securities from Europe, Australasia and the Far East. The Underlying Index generally represents approximately 50% of the free float-adjusted market capitalization of the MSCI EAFE® Index and consists of those securities classified by MSCI as most representing the growth style. Securities classified as growth style generally tend to have higher forecasted earnings growth rates, lower book value to price ratios, lower forward earnings to price ratios and lower dividend yields than securities representing the value style. MSCI uses a specialized framework to attribute both value and growth style characteristics to each security within the MSCI EAFE® Index. Each security is evaluated based on certain value factors and growth factors, which are then used to calculate a value score and growth score. Based upon these two scores, MSCI determines the extent to which each security is assigned to the value or growth style. It is possible for a single security to have representation in both the value and growth style indexes, however, no more than 100% of a security’s float-adjusted market capitalization will be included within the combined style framework.

BFA uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to “beat” the index it tracks and does not seek temporary defensive positions when markets decline or appear overvalued.

Indexing may eliminate the chance that the Fund will substantially outperform the Underlying Index but also may reduce some of the risks of active management, such as poor security selection. Indexing seeks to achieve lower costs and better after-tax performance by keeping portfolio turnover low in comparison to actively managed investment companies.

BFA uses a representative sampling indexing strategy to manage the Fund. “Representative sampling” is an indexing strategy that involves investing in a representative sample of securities that collectively has an investment profile similar to the Underlying Index. The securities selected are expected to have, in the aggregate, investment characteristics (based on factors such as market capitalization and industry weightings), fundamental characteristics (such as return variability and yield) and liquidity measures similar to those of the Underlying Index. The Fund may or may not hold all of the securities in the Underlying Index.

The Fund generally invests at least 90% of its assets in securities of the Underlying Index and in depositary

S-2   


Table Of Contents



receipts representing securities of the Underlying Index. The Fund may invest the remainder of its assets in securities not included in the Underlying Index, but which BFA believes will help the Fund track the Underlying Index and in other investments including futures contracts, options on futures contracts, options and swaps as well as cash and cash equivalents, including shares of money market funds advised by BFA or its affiliates.

The Fund may lend securities representing up to one-third of the value of the Fund’s total assets (including the value of the collateral received).

The Underlying Index is sponsored by an organization (the “Index Provider”) that is independent of the Fund and BFA. The Index Provider determines the composition and relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index. The Fund’s Index Provider is MSCI Inc. (“MSCI”).

Industry Concentration Policy. The Fund will concentrate its investments (i.e., hold 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. For purposes of this limitation, securities of the U.S. government (including its agencies and instrumentalities) and repurchase agreements collateralized by U.S. government securities are not considered to be issued by members of any industry.

Summary of Principal Risks

As with any investment, you could lose all or part of your investment in the Fund, and the Fund’s performance could trail that of other investments. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund’s net asset value per share (“NAV”), trading price, yield, total return and ability to meet its investment objective.

Asset Class Risk. Securities in the Underlying Index or in the Fund’s portfolio may underperform in comparison to the general securities markets or other asset classes.

Concentration Risk. To the extent that the Fund’s investments are concentrated in a particular issuer, region, country, market, industry or asset class, the Fund may be susceptible to loss due to adverse occurrences affecting that issuer, region, country, market, industry or asset class.

Consumer Staples Sector Risk. The consumer staples sector may be affected by marketing campaigns, changes in consumer demands, government regulations and changes in commodity prices.

Currency Risk. Because the Fund’s NAV is determined in U.S. dollars, the Fund’s NAV could decline if the currency of a non-U.S. market in which the Fund invests depreciates against the U.S. dollar.

Equity Securities Risk. Equity securities are subject to changes in value and their values may be more volatile than other asset classes.

Geographic Risk. A natural or other disaster could occur in a geographic region in which the Fund invests, which could affect the economy or particular business operations of companies in the specific geographic region, causing an

S-3   


Table Of Contents



adverse impact on the Fund’s investments in the affected region.

Growth Securities Risk. The Fund invests in growth securities, which may be more volatile than other types of investments.

Industrials Sector Risk. The industrials sector is affected by changes in the supply and demand for products and services, product obsolescence, claims for environmental damage or product liability and general economic conditions, among other factors.

Issuer Risk. Fund performance depends on the performance of individual securities to which the Fund has exposure. Changes to the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA’s investment management strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares, losses from trading in secondary markets, periods of high volatility and disruption in the creation/redemption process of the Fund. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV.

Materials Sector Risk. Companies in the materials sector may be adversely impacted by the volatility of commodity prices, exchange rates, depletion of resources, over-production, litigation and government regulations, among other factors.

Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers are subject to the risks associated with investing in those non-U.S. markets, such as heightened risks of inflation or nationalization. The Fund may lose money due to political, economic and geographic events affecting a non-U.S. issuer or market. The Fund is specifically exposed to Asian Economic Risk and European Economic Risk.

Passive Investment Risk. The Fund is not actively managed and BFA does not attempt to take defensive positions under any market conditions, including declining markets.

Privatization Risk. Some countries in which the Fund invests have begun a process of privatizing certain entities and industries. Privatized entities may lose money or be re-nationalized.

Risk of Investing in Japan. The Japanese economy may be subject to considerable degrees of economic, political and social instability, which could have a negative impact on Japanese securities.

Risk of Investing in the United Kingdom. The Fund’s investment in British issuers may subject the Fund to regulatory, political, currency, security, and economic risk specific to the United Kingdom. The United Kingdom has one of the largest economies in Europe, and the United States and other European countries are substantial trading partners of the United Kingdom. As a result, the British economy may be impacted by changes to the economic health of the United States and other

S-4   


Table Of Contents



European countries. The British economy, along with certain other European economies, experienced a significant economic slowdown during the recent financial crisis; certain British financial institutions were severely under-capitalized and required government intervention to survive.

Securities Lending Risk. The Fund may engage in securities lending. Securities lending involves the risk that the Fund may lose money because the borrower of the Fund’s loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Security Risk. Some countries and regions in which the Fund invests have experienced security concerns. Incidents involving a country’s or region’s security may cause uncertainty in these markets and may adversely affect their economies and the Fund’s investments.

Tracking Error Risk. The performance of the Fund may diverge from that of the Underlying Index. Because the Fund employs a representative sampling strategy, the Fund may experience tracking error to a greater extent than a fund that seeks to replicate an index.

Valuation Risk. The value of the securities in the Fund’s portfolio may change on days when shareholders will not be able to purchase or sell the Fund’s shares.

1 After-tax returns in the table above are calculated using the historical highest individual U.S. federal marginal income tax rates and do not reflect the impact of state or local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown, and after-tax returns shown are not relevant to tax-exempt investors or investors who hold shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts (“IRAs”). Fund returns after taxes on distributions and sale of Fund shares are calculated assuming that an investor has sufficient capital gains of the same character from other investments to offset any capital losses from the sale of Fund shares. As a result, Fund returns after taxes on distributions and sale of Fund shares may exceed Fund returns before taxes and/or returns after taxes on distributions.

Management

Investment Adviser. BlackRock Fund Advisors.

Portfolio Managers. Rene Casis, Diane Hsiung and Greg Savage (the “Portfolio Managers”) are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager supervises a portfolio management team. Mr. Casis, Ms. Hsiung and Mr. Savage have been Portfolio Managers of the Fund since 2010, 2008 and 2008, respectively.

Purchase and Sale of Fund Shares

The Fund is an exchange-traded fund (commonly referred to as an “ETF”). Individual Fund shares may only be purchased and sold on a national securities exchange through a broker-dealer. The price of Fund shares is based on market price, and because ETF shares trade at market prices rather than NAV, shares may trade at a price greater than NAV (a premium) or less than NAV (a discount). The Fund will only issue or redeem shares that have been aggregated into blocks of 400,000 shares or multiples thereof (“Creation Units”) to authorized participants who have entered into agreements with the Fund’s distributor. The Fund generally will issue or redeem Creation Units in return for a designated portfolio of securities (and an amount of cash) that the Fund specifies each day.

Tax Information

The Fund intends to make distributions that may be taxable to you as ordinary income or capital gains, unless you are investing through a tax-deferred arrangement such as a 401(k) plan or an IRA.

Payments to Broker-Dealers and other Financial Intermediaries

If you purchase shares of the Fund through a broker-dealer or other financial intermediary (such as a bank), BFA or other related companies may pay the intermediary for marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems or other services related to the sale or promotion of the Fund. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.

More Information About the Fund

This Prospectus contains important information about investing in the Fund. Please read this Prospectus carefully before you make any investment decisions. Additional information regarding the Fund is available at www.iShares.com.

BFA is the investment adviser to the Fund. Shares of the Fund are listed for trading on NYSE Arca, Inc. (“NYSE Arca”). The market price for a share of the Fund may be different from the Fund’s most recent NAV.

ETFs are funds that trade like other publicly-traded securities. The Fund is designed to track an index. Similar to shares of an index mutual fund, each share of the Fund represents a partial ownership in an underlying portfolio of securities intended to track a market index. Unlike shares of a mutual fund, which can be bought and redeemed from the issuing fund by all shareholders at a price based on NAV, shares of the Fund may be purchased or redeemed directly from the Fund at NAV solely by authorized participants. Also unlike shares of a mutual fund, shares of the Fund are listed on a national securities exchange and trade in the secondary market at market prices that change throughout the day.

The Fund invests in a particular segment of the securities markets and seeks to track the performance of a securities index that generally is not representative of the market as a whole. The Fund is designed to be used as part of broader asset allocation strategies. Accordingly, an investment in the Fund should not constitute a complete investment program.

An index is a theoretical financial calculation while the Fund is an actual investment portfolio. The performance of the Fund and the Underlying Index may vary due to transaction costs, non-U.S. currency valuations, asset valuations, corporate actions (such as mergers and spin-offs), timing variances and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions (such as diversification requirements) that apply to the Fund but not to the Underlying Index or to the use of representative sampling. “Tracking error” is the difference between the performance (return) of the Fund’s portfolio and that of the Underlying Index. BFA expects that, over time, the Fund’s tracking error will not exceed 5%. Because the Fund uses a representative sampling indexing strategy, it can be expected to have a larger tracking error than if it used a replication indexing strategy. “Replication” is an indexing strategy in which a fund invests in substantially all of the securities in its underlying index in approximately the same proportions as in the underlying index.

An investment in the Fund is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, BFA or any of its affiliates.

The Fund’s investment objective and the Underlying Index may be changed without shareholder approval.

A Further Discussion of Principal Risks

The Fund is subject to various risks, including the principal risks noted below, any of which may adversely affect the Fund’s NAV, trading price, yield, total return and ability to meet its investment objective. You could lose all or part of your investment in the Fund, and the Fund could underperform other investments.

Asian Economic Risk. Certain Asian economies have experienced over-extension of credit, currency devaluations and restrictions, high unemployment, high inflation, decreased exports and economic recessions. Economic events in any one Asian country may have a significant economic effect on the entire Asian region, as well as on major trading partners outside Asia, and any adverse event in the Asian markets may have a significant adverse effect on other Asian economies.

Asset Class Risk. The securities in the Underlying Index or in the Fund’s portfolio may underperform the returns of other securities or indexes that track other countries, groups of countries, regions, industries, groups of industries, markets, asset classes or sectors. Various types of securities or indexes tend to experience cycles of outperformance and underperformance in comparison to the general securities markets.

Concentration Risk. To the extent that the Fund’s portfolio reflects the Underlying Index’s concentration in the securities of a particular issuer or issuers in a particular country, group of countries, region, market, industry, group of industries, sector or asset class, the Fund may be adversely affected by the performance of those securities, may be subject to increased price volatility and may be more susceptible to adverse economic, market, political or regulatory occurrences affecting that issuer, country, group of countries, region, market, industry, group of industries, sector or asset class.

Consumer Staples Sector Risk. The Fund invests in companies in the consumer staples sector. The consumer staples sector may be affected by the permissibility of using various food additives and production methods, marketing campaigns and other factors affecting consumer demand. Tobacco companies, in particular, may be adversely affected by new laws, regulations and litigation. The consumer staples sector may also be adversely affected by changes or trends in commodity prices, which may be influenced or characterized by unpredictable factors.

Currency Risk. Because the Fund’s NAV is determined on the basis of the U.S. dollar, investors may lose money if the currency of a non-U.S. market in which the Fund invests depreciates against the U.S. dollar, even if the local currency value of the Fund’s holdings in that market increases.

Equity Securities Risk. The Fund invests in equity securities, which are subject to changes in value that may be attributable to market perception of a particular issuer or to general stock market fluctuations that affect all issuers. Investments in equity securities may be more volatile than investments in other asset classes.

European Economic Risk. The Economic and Monetary Union of the European Union (the “EU”) requires member countries to comply with restrictions on inflation rates, deficits, interest rates, debt levels and fiscal and monetary controls, each of which may

significantly affect every country in Europe. Decreasing imports or exports, changes in governmental or EU regulations on trade, changes in the exchange rate of the euro, the default or threat of default by an EU member country on its sovereign debt, and/or an economic recession in an EU member country may have a significant adverse effect on the economies of EU member countries and on major trading partners outside Europe. The European financial markets have recently experienced volatility and have been adversely affected by concerns about economic downturns, credit rating downgrades, rising government debt levels and possible default on or restructuring of government debt in several European countries, including Greece, Ireland, Italy, Portugal and Spain. A default or debt restructuring by any European country would adversely impact holders of that country’s debt, and sellers of credit default swaps linked to that country’s creditworthiness, which may be located in countries other than those listed in the previous sentence. These events have adversely affected the value and exchange rate of the euro and may continue to significantly affect the economies of every country in Europe, including EU member countries that do not use the euro and non-EU member countries.

Geographic Risk. Some markets in which the Fund invests are located in parts of the world that have historically been prone to natural disasters, such as earthquakes, volcanoes, droughts, floods, hurricanes and tsunamis, and are economically sensitive to environmental events. Any natural or other disaster could have a significant adverse impact on the economies of these geographic areas, causing an adverse impact on the Fund’s investments in the affected region.

Growth Securities Risk. Growth companies are companies whose earnings growth potential appears to be greater than the market in general and whose revenue growth is expected to continue for an extended period. Stocks of growth companies or “growth securities” have market values that may be more volatile than those of other types of investments. Growth securities typically do not pay a dividend, which can help cushion stock prices in market downturns and reduce potential losses.

Industrials Sector Risk. The stock prices of companies in the industrials sector are affected by supply and demand, both for their specific product or service and for industrials sector products in general. The products of manufacturing companies may face obsolescence due to rapid technological developments and frequent new product introduction. Government regulations, world events, economic conditions and exchange rates affect the performance of companies in the industrials sector. Companies in the industrials sector may be adversely affected by liability for environmental damage, product liability claims and exchange rates. The industrials sector may also be adversely affected by changes or trends in commodity prices, which may be influenced by unpredictable factors.

Issuer Risk. The performance of the Fund depends on the performance of individual securities to which the Fund has exposure. Any issuer of these securities may perform poorly, causing the value of its securities to decline. Poor performance may be caused by poor management decisions, competitive pressures, changes in technology, expiration of patent protection, disruptions in supply, labor problems or shortages, corporate restructurings, fraudulent disclosures or other factors. Issuers may, in times

of distress or at their own discretion, decide to reduce or eliminate dividends, which may also cause their stock prices to decline.

Management Risk. The Fund may not fully replicate the Underlying Index and may hold securities not included in the Underlying Index. As a result, the Fund is subject to the risk that BFA’s investment management strategy, the implementation of which is subject to a number of constraints, may not produce the intended results.

Market Risk. The Fund could lose money due to short-term market movements and over longer periods during market downturns. Securities may decline in value due to factors affecting securities markets generally or particular industries represented in the markets. The value of a security may decline due to general market conditions, economic trends or events that are not specifically related to the issuer of the security or to factors that affect a particular industry or industries. During a general downturn in the securities markets, multiple asset classes may be negatively affected.

Market Trading Risk

Absence of Active Market. Although shares of the Fund are listed for trading on one or more stock exchanges, there can be no assurance that an active trading market for such shares will develop or be maintained.

Risk of Secondary Listings. The Fund’s shares may be listed or traded on U.S. and non-U.S. stock exchanges other than the U.S. stock exchange where the Fund’s primary listing is maintained. There can be no assurance that the Fund’s shares will continue to trade on any such stock exchange or in any market or that the Fund’s shares will continue to meet the requirements for listing or trading on any exchange or in any market. The Fund’s shares may be less actively traded in certain markets than others, and investors are subject to the execution and settlement risks and market standards of the market where they or their broker direct their trades for execution. Certain information available to investors who trade Fund shares on a U.S. stock exchange during regular U.S. market hours may not be available to investors who trade in other markets, which may result in secondary market prices in such markets being less efficient.

Secondary Market Trading Risk. Shares of the Fund may trade in the secondary market at times when the Fund does not accept orders to purchase or redeem shares. At such times, shares may trade in the secondary market with more significant premiums or discounts than might be experienced at times when the Fund accepts purchase and redemption orders.

Secondary market trading in Fund shares may be halted by a stock exchange because of market conditions or other reasons. In addition, trading in Fund shares on a stock exchange or in any market may be subject to trading halts caused by extraordinary market volatility pursuant to “circuit breaker” rules on the stock exchange or market. There can be no assurance that the requirements necessary to maintain the listing or trading of Fund shares will continue to be met or will remain unchanged.

Shares of the Fund May Trade at Prices Other Than NAV. Shares of the Fund trade on stock exchanges at prices at, above or below their most recent NAV. The NAV of the Fund is calculated at the end of each business day and fluctuates with changes in the market value of the Fund’s holdings since the most recent calculation. The trading

prices of the Fund’s shares fluctuate continuously throughout trading hours based on market supply and demand rather than NAV. The trading prices of the Fund’s shares may deviate significantly from NAV during periods of market volatility. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV. However, because shares can be created and redeemed in Creation Units at NAV (unlike shares of many closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their NAVs), BFA believes that large discounts or premiums to the NAV of the Fund are not likely to be sustained over the long-term. While the creation/redemption feature is designed to make it likely that the Fund’s shares normally will trade on stock exchanges at prices close to the Fund’s next calculated NAV, exchange prices are not expected to correlate exactly with the Fund’s NAV due to timing reasons as well as market supply and demand factors. In addition, disruptions to creations and redemptions or extreme market volatility may result in trading prices for shares of the Fund that differ significantly from its NAV.

Costs of Buying or Selling Fund Shares. Buying or selling Fund shares on an exchange involves two types of costs that apply to all securities transactions. When buying or selling shares of the Fund through a broker, you will likely incur a brokerage commission or other charges imposed by brokers as determined by that broker. In addition, you may incur the cost of the “spread” – that is, the difference between what investors are willing to pay for Fund shares (the “bid” price) and the price at which they are willing to sell Fund shares (the “ask” price). Because of the costs inherent in buying or selling Fund shares, frequent trading may detract significantly from investment results and an investment in Fund shares may not be advisable for investors who anticipate regularly making small investments.

Materials Sector Risk. Companies in the materials sector could be adversely affected by commodity price volatility, exchange rates, import controls, increased competition, depletion of resources, technical progress, labor relations, exchange rates and government regulations, among other factors. Also, companies in the materials sector are at risk of liability for environmental damage and product liability claims. Production of materials may exceed demand as a result of market imbalances or economic downturns, leading to poor investment returns.

Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers are subject to all of the risks of investing in the markets where such issuers are located, including heightened risks of inflation or nationalization and market fluctuations caused by economic and political developments. As a result of investing in non-U.S. securities, the Fund may be subject to increased risk of loss caused by any of the factors listed below:

  • Lower levels of liquidity and market efficiency;
  • Greater securities price volatility;
  • Exchange rate fluctuations and exchange controls;
  • Less availability of public information about issuers;
  • Limitations on foreign ownership of securities;
  • Imposition of withholding or other taxes;
  • Imposition of restrictions on the expatriation of the funds or other assets of the Fund;
  • Higher transaction and custody costs and delays in settlement procedures;
  • Difficulties in enforcing contractual obligations;
  • Lower levels of regulation of the securities market;
  • Weaker accounting, disclosure and reporting requirements; and
  • Legal principles related to corporate governance, directors’ fiduciary duties and liabilities and stockholders’ rights in markets in which the Fund invests may differ and/or may not be as extensive or protective as those that apply in the United States.

Passive Investment Risk. The Fund is not actively managed and may be affected by a general decline in market segments related to the Underlying Index. The Fund invests in securities included in, or representative of, the Underlying Index regardless of their investment merits. BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

Privatization Risk. Some countries in which the Fund invests have begun a process of privatizing certain entities and industries. In some instances, investors in newly privatized entities have suffered losses due to the inability of the newly privatized entities to adjust quickly to a competitive environment or changing regulatory and legal standards or, in some cases, due to re-nationalization of such privatized entities. There is no assurance that such losses will not recur.

Risk of Investing in Japan. Japan may be subject to political, economic, nuclear, and labor risks. Any of these risks, individually or in the aggregate, can impact an investment made in Japan.

  • Political Risk. Historically, Japan has had unpredictable national politics and may experience frequent political turnover. Future political developments may lead to changes in policy that might adversely affect the Fund’s investments.
  • Large Government Debt Risk. The Japanese economy faces several concerns, including a financial system with large levels of nonperforming loans, over-leveraged corporate balance sheets, extensive cross-ownership by major corporations, a changing corporate governance structure, and large government deficits. These issues may cause a slowdown of the Japanese economy.
  • Currency Risk. The Japanese yen has fluctuated widely at times and any increase in its value may cause a decline in exports that could weaken the economy.
  • Nuclear Risk. The nuclear power plant catastrophe in Japan in March of 2011 may have short-term and long-term effects on the nuclear energy industry, the extent of which are currently unknown.
  • Labor Risk. Japan has an aging workforce. It is a labor market that is undergoing fundamental structural changes, as traditional lifetime employment clashes with the need for increased labor mobility, which may adversely affect Japan’s economic competitiveness.
  • Geographic Risk. Natural disasters, such as earthquakes, could occur in Japan or surrounding areas and could negatively affect the Japanese economy, and, in turn, could negatively affect the Fund.

Risk of Investing in the United Kingdom. Investment in British issuers may subject the Fund to regulatory, political, currency, security, and economic risk specific to the United Kingdom. The British economy relies heavily on export of financial services to the United States and other European countries. A prolonged slowdown in the financial services sector will have a negative impact on the British economy. In the past, the United Kingdom has been a target of terrorism. Acts of terrorism in the United Kingdom or against British interests abroad may cause uncertainty in the British financial markets and adversely affect the performance of the issuers to which the Fund has exposure. The British economy, along with the United States and certain other European economies, experienced a significant economic slowdown during the recent financial crisis.

Securities Lending Risk. The Fund may engage in securities lending. Securities lending involves the risk that the Fund may lose money because the borrower of the Fund’s loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for the loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Security Risk. Some geographic areas in which the Fund invests have experienced acts of terrorism or strained international relations due to territorial disputes, historical animosities or other defense concerns. These situations may cause uncertainty in the markets of these geographic areas and may adversely affect the performance of their economies.

Tracking Error Risk. Imperfect correlation between the Fund’s portfolio securities and those in the Underlying Index, rounding of prices, changes to the Underlying Index and regulatory requirements may cause tracking error, which is the divergence of the Fund’s performance from that of the Underlying Index. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Underlying Index does not. Because the Fund employs a representative sampling strategy, the Fund may experience tracking error to a greater extent than a fund that seeks to replicate an index.

Valuation Risk. Because non-U.S. exchanges may be open on days when the Fund does not price its shares, the value of the securities in the Fund’s portfolio may change on days when shareholders will not be able to purchase or sell the Fund’s shares. In addition, for purposes of calculating the Fund’s NAV, the value of assets denominated in non-U.S. currencies is converted into U.S. dollars using exchange rates deemed appropriate by BFA. This conversion may result in a difference between the prices used to calculate the Fund’s NAV and the prices used by the Underlying Index, which, in turn, could result in a difference between the Fund’s performance and the performance of the Underlying Index.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

Australasian Economic Risk. The economies of Australasia, which include Australia and New Zealand, are dependent on exports from the agricultural and mining sectors. This makes Australasian economies susceptible to fluctuations in the commodity markets. Australasian economies are also increasingly dependent on their growing service industries. Because the economies of Australasia are dependent on the economies of Asia, Europe and the United States as key trading partners and investors, reduction in spending by any of these trading partners on Australasian products and services, or negative changes in any of these economies, may cause an adverse impact on some or all of the Australasian economies.

Consumer Discretionary Sector Risk. The success of consumer product manufacturers and retailers is tied closely to the performance of domestic and international economies, interest rates, exchange rates, competition, consumer confidence, changes in demographics and consumer preferences. Companies in the consumer discretionary sector depend heavily on disposable household income and consumer spending, and may be strongly affected by social trends and marketing campaigns. These companies may be subject to severe competition, which may have an adverse impact on their profitability.

Financial Sector Risk. Companies in the financial sector of an economy are often subject to governmental regulation and, recently, government intervention and the potential for additional regulation, which may adversely affect the scope of their activities, the prices they can charge and the amount of capital they must maintain. Governmental regulation may change frequently and may have significant adverse consequences for companies in the financial sector, including effects not intended by such regulation. The impact of recent or future regulation in various countries on any individual financial company or on the sector as a whole cannot be predicted. Certain risks may impact the value of investments in the financial sector more severely than investments outside this sector, including the risks associated with companies that operate with substantial financial leverage. Companies in the financial sector may also be adversely affected by increases in interest rates and loan losses, decreases in the availability of money or asset valuations, credit rating downgrades and adverse conditions in other related markets. Over the past few years, the deterioration of the credit markets has impacted a broad range of mortgage, asset-backed, auction rate, sovereign debt and other markets, including U.S. and non-U.S. credit and interbank money markets, thereby affecting a wide range of financial institutions and markets. This situation has created instability in the financial markets and caused certain financial companies to incur large losses. Some financial companies have experienced declines in the valuations of their assets, taken actions to raise capital (such as the issuance of debt or equity securities), or even ceased operations. Some financial companies have borrowed significant amounts of capital from governments and may face future government-imposed restrictions on their businesses or increased government intervention. These actions have caused the securities of many financial

companies to decline in value. Insurance companies, in particular, may be subject to severe price competition, which may have an adverse impact on their profitability.

Health Care Sector Risk. The profitability of companies in the health care sector may be affected by extensive government regulations, restrictions on government reimbursement for medical expenses, rising costs of medical products and services, pricing pressure, an increased emphasis on outpatient services, limited number of products, industry innovation, changes in technologies and other market developments. Many health care companies are heavily dependent on patent protection. The expiration of patents may adversely affect the profitability of these companies. Many health care companies are subject to extensive litigation based on product liability and similar claims. Health care companies are subject to competitive forces that may make it difficult to raise prices and, in fact, may result in price discounting. Many new products in the health care sector may be subject to regulatory approvals. The process of obtaining such approvals may be long and costly. Companies in the health care sector may be thinly capitalized and may be susceptible to product obsolescence.

Information Technology Sector Risk. Information technology companies face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Like other technology companies, information technology companies may have limited product lines, markets, financial resources or personnel. The products of information technology companies may face obsolescence due to rapid technological developments and frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Companies in the information technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies.

Portfolio Holdings Information

A description of the Trust’s policies and procedures with respect to the disclosure of the Fund’s portfolio securities is available in the Fund’s Statement of Additional Information (“SAI”). The top holdings of the Fund can be found at www.iShares.com. Fund fact sheets provide information regarding the Fund’s top holdings and may be requested by calling 1-800-iShares (1-800-474-2737).

Management

Investment Adviser. As investment adviser, BFA has overall responsibility for the general management and administration of the Trust. BFA provides an investment program for the Fund and manages the investment of the Fund’s assets. In managing the Fund, BFA may draw upon the research and expertise of its asset management affiliates with respect to certain portfolio securities. In seeking to achieve the Fund’s investment objective, BFA uses teams of portfolio managers, investment strategists and other investment specialists. This team approach brings together many disciplines and leverages BFA’s extensive resources.

Pursuant to the Investment Advisory Agreement between BFA and the Trust (entered into on behalf of the Fund), BFA is responsible for substantially all expenses of the

Fund, except interest expenses, taxes, brokerage expenses, future distribution fees or expenses and extraordinary expenses.

For its investment advisory services to the Fund, BFA is entitled to receive a management fee from the Fund based on a percentage of the Fund’s average daily net assets, at the annual rate of 0.40%.

BFA is located at 400 Howard Street, San Francisco, CA 94105. It is a wholly owned subsidiary of BTC, which in turn is indirectly wholly-owned by BlackRock, Inc. (“BlackRock”). As of September 30, 2011, BTC and its affiliates, including BFA and BlackRock, provided investment advisory services for assets in excess of $3.35 trillion. BFA, BTC, BlackRock Execution Services, BlackRock and their affiliates deal, trade and invest for their own accounts in the types of securities in which the Fund may also invest.

A discussion regarding the basis for the Trust’s Board of Trustees’ (the “Board”) approval of the Investment Advisory Agreement with BFA is available in the Fund’s annual report for the period ended July 31.

Portfolio Managers. Rene Casis, Diane Hsiung and Greg Savage are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager is responsible for various functions related to portfolio management, including, but not limited to, investing cash inflows, coordinating with members of his or her portfolio management team to focus on certain asset classes, implementing investment strategy, researching and reviewing investment strategy and overseeing members of his or her portfolio management team that have more limited responsibilities.

Rene Casis has been employed by BFA (formerly, Barclays Global Fund Advisors (“BGFA”)) and BTC (formerly, Barclays Global Investors, N.A. (“BGI”)) as a senior portfolio manager since 2009. From 2005 to 2009, Mr. Casis was a trader at Barclays Capital. Prior to that, Mr. Casis was a portfolio manager from 2000 to 2005 for BGFA and BGI. Mr. Casis has been a Portfolio Manager of the Fund since 2010.

Diane Hsiung has been employed by BFA and BTC as a senior portfolio manager since 2007. Prior to that, Ms. Hsiung was a portfolio manager from 2002 to 2006 for BGFA and BGI. Ms. Hsiung has been a Portfolio Manager of the Fund since 2008.

Greg Savage has been employed by BFA and BTC as a senior portfolio manager since 2006. Prior to that, Mr. Savage was a portfolio manager from 2001 to 2006 for BGFA and BGI. Mr. Savage has been a Portfolio Manager of the Fund since 2008.

The Fund’s SAI provides additional information about the Portfolio Managers’ compensation, other accounts managed by the Portfolio Managers and the Portfolio Managers’ ownership (if any) of shares in the Fund.

Administrator, Custodian and Transfer Agent. State Street Bank and Trust Company (“State Street”) is the administrator, custodian and transfer agent for the Fund.

Conflicts of Interest. BFA wants you to know that there are certain entities with which BFA has relationships that may give rise to conflicts of interest, or the appearance of conflicts of interest. These entities include the following: BFA’s affiliates (including BlackRock and The PNC Financial Services Group, Inc., and each of their

affiliates, directors, partners, trustees, managing members, officers and employees (collectively, the “Affiliates”)) and BlackRock’s significant shareholder, Barclays Bank PLC and its affiliates, including Barclays PLC (each, an “Entity” and together, the “Entities”).

The activities of BFA, the Affiliates and the Entities in the management of, or their interest in, their own accounts and other accounts they manage, may present conflicts of interest that could disadvantage the Fund and its shareholders. BFA and its Affiliates or the Entities provide investment management services to other funds and discretionary managed accounts that may follow an investment program similar to that of the Fund. BFA, its Affiliates and the Entities are involved worldwide with a broad spectrum of financial services and asset management activities and may engage in the ordinary course of business in activities in which their interests or the interests of their clients may conflict with those of the Fund. BFA, one or more of the Affiliates or the Entities acts, or may act, as an investor, investment banker, research provider, investment manager, financier, underwriter, advisor, market maker, trader, prime broker, lender, agent or principal, and have other direct and indirect interests, in securities, currencies and other instruments in which the Fund may directly or indirectly invest. Thus, it is likely that the Fund will have multiple business relationships with and will invest in, engage in transactions with, make voting decisions with respect to, or obtain services from, entities for which BFA, an Affiliate or an Entity performs or seeks to perform investment banking or other services.

BFA or one or more Affiliates or Entities may engage in proprietary trading and advise accounts and funds that have investment objectives similar to those of the Fund and/or that engage in and compete for transactions in the same types of securities, currencies and other instruments as the Fund, including in securities issued by other open-end and closed-end investment management companies, including investment companies that are affiliated with the Fund and BFA, to the extent permitted under the Investment Company Act of 1940, as amended (the “1940 Act”). The trading activities of BFA, these Affiliates and Entities are carried out without reference to positions held directly or indirectly by the Fund and may result in BFA, an Affiliate or an Entity having positions that are adverse to those of the Fund.

No Affiliate or Entity is under any obligation to share any investment opportunity, idea or strategy with the Fund. As a result, an Affiliate or an Entity may compete with the Fund for appropriate investment opportunities. As a result of this and several other factors, the results of the Fund’s investment activities may differ from those of an Affiliate or an Entity and of other accounts managed by an Affiliate or an Entity, and it is possible that the Fund could sustain losses during periods in which one or more Affiliates or Entities and other accounts achieve profits on their trading for proprietary or other accounts. The opposite result is also possible.

The Fund may, from time to time, enter into transactions in which BFA or an Affiliate’s or an Entity’s clients have an interest adverse to the Fund. Furthermore, transactions undertaken by Affiliate-advised clients may adversely impact the Fund. Transactions by one or more Affiliate- or Entity-advised clients or BFA may have the effect of diluting or otherwise disadvantaging the values, prices or investment strategies of the Fund.

An Entity may maintain securities indices as part of its product offerings. Index-based funds seek to track the performance of securities indices and may use the name of the index in the fund name. Index providers, including the Entities, may be paid licensing fees for use of their indices or index names. Entities will not be obligated to license their indices to BFA and its Affiliates, and BFA and its Affiliates will not be assured that the terms of any index licensing agreement with the Entities will be as favorable as those terms offered to other index licensees.

The Fund’s activities may be limited because of regulatory restrictions applicable to one or more Affiliates or Entities, and/or their internal policies designed to comply with such restrictions. In addition, the Fund may invest in securities of companies with which an Affiliate or an Entity has or is trying to develop investment banking relationships or in which an Affiliate or an Entity has significant debt or equity investments. The Fund also may invest in securities of companies for which an Affiliate or an Entity provides or may some day provide research coverage. An Affiliate or an Entity may have business relationships with and purchase or distribute or sell services or products from or to distributors, consultants or others who recommend the Fund or who engage in transactions with or for the Fund, and may receive compensation for such services. The Fund may also make brokerage and other payments to Affiliates or Entities in connection with the Fund’s portfolio investment transactions.

Pursuant to a securities lending program approved by the Board, the Fund has retained an Affiliate of BFA to serve as the securities lending agent for the Fund to the extent that the Fund participates in the securities lending program. For these services, the lending agent may receive a fee from the Fund, including a fee based on the returns earned on the Fund’s investment of the cash received as collateral for any loaned securities. In addition, one or more Affiliates may be among the entities to which the Fund may lend its portfolio securities under the securities lending program.

The activities of BFA, the Affiliates or Entities may give rise to other conflicts of interest that could disadvantage the Fund and its shareholders. BFA has adopted policies and procedures designed to address these potential conflicts of interest. See the Fund’s SAI for further information.

Shareholder Information

Additional shareholder information, including how to buy and sell shares of the Fund, is available free of charge by calling toll-free: 1-800-iShares (1-800-474-2737) or visiting our website at www.iShares.com.

Buying and Selling Shares. Shares of the Fund may be acquired or redeemed directly from the Fund only in Creation Units or multiples thereof, as discussed in the Creations and Redemptions section of this Prospectus. Only an Authorized Participant (as defined in the Creations and Redemptions section) may engage in creation or redemption transactions directly with the Fund. Once created, shares of the Fund generally trade in the secondary market in amounts less than a Creation Unit.

Shares of the Fund are listed on a national securities exchange for trading during the trading day. Shares can be bought and sold throughout the trading day like shares of other publicly-traded companies. The Trust does not impose any minimum investment

for shares of the Fund purchased on an exchange. The Fund’s shares trade under the trading symbol “EFG.”

Buying or selling Fund shares on an exchange involves two types of costs that may apply to all securities transactions. When buying or selling shares of the Fund through a broker, you will likely incur a brokerage commission or other charges determined by your broker. The commission is frequently a fixed amount and may be a significant proportional cost for investors seeking to buy or sell small amounts of shares. In addition, you may incur the cost of the “spread” – that is, any difference between the bid price and the ask price. The spread varies over time for shares of the Fund based on its trading volume and market liquidity, and is generally lower if the Fund has a lot of trading volume and market liquidity, and higher if the Fund has little trading volume and market liquidity.

The Board has adopted a policy of not monitoring for frequent purchases and redemptions of Fund shares (“frequent trading”) that appear to attempt to take advantage of a potential arbitrage opportunity presented by a lag between a change in the value of the Fund’s portfolio securities after the close of the primary markets for the Fund’s portfolio securities and the reflection of that change in the Fund’s NAV (“market timing”), because the Fund generally sells and redeems its shares directly through transactions that are in-kind and/or for cash, subject to the conditions described below under Creations and Redemptions. The Board has not adopted a policy of monitoring for other frequent trading activity because shares of the Fund are listed for trading on a national securities exchange.

The national securities exchange on which the Fund’s shares are listed is open for trading Monday through Friday and is closed on weekends and the following holidays: New Year’s Day, Martin Luther King, Jr. Day, Presidents’ Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day. The Fund’s primary listing exchange is NYSE Arca.

Section 12(d)(1) of the 1940 Act restricts investments by investment companies in the securities of other investment companies. Registered investment companies are permitted to invest in the Fund beyond the limits set forth in Section 12(d)(1), subject to certain terms and conditions set forth in SEC rules or in an SEC exemptive order issued to the Trust. In order for a registered investment company to invest in shares of the Fund beyond the limitations of Section 12(d)(1) pursuant to the exemptive relief obtained by the Trust, the registered investment company must enter into an agreement with the Trust.

Book Entry. Shares of the Fund are held in book-entry form, which means that no stock certificates are issued. The Depository Trust Company (“DTC”) or its nominee is the record owner of all outstanding shares of the Fund and is recognized as the owner of all shares for all purposes.

Investors owning shares of the Fund are beneficial owners as shown on the records of DTC or its participants. DTC serves as the securities depository for shares of the Fund. DTC participants include securities brokers and dealers, banks, trust companies, clearing corporations and other institutions that directly or indirectly maintain a custodial relationship with DTC. As a beneficial owner of shares, you are not entitled to

receive physical delivery of stock certificates or to have shares registered in your name, and you are not considered a registered owner of shares. Therefore, to exercise any right as an owner of shares, you must rely upon the procedures of DTC and its participants. These procedures are the same as those that apply to any other securities that you hold in book-entry or “street name” form.

Share Prices. The trading prices of the Fund’s shares in the secondary market generally differ from the Fund’s daily NAV and are affected by market forces such as supply and demand, economic conditions and other factors. Information regarding the intraday value of shares of the Fund, also known as the “indicative optimized portfolio value” (“IOPV”), is disseminated every 15 seconds throughout the trading day by the national securities exchange on which the Fund’s shares are listed or by market data vendors or other information providers. The IOPV is based on the current market value of the securities and/or cash required to be deposited in exchange for a Creation Unit. The IOPV does not necessarily reflect the precise composition of the current portfolio of securities held by the Fund at a particular point in time or the best possible valuation of the current portfolio. Therefore, the IOPV should not be viewed as a “real-time” update of the Fund’s NAV, which is computed only once a day. The IOPV is generally determined by using both current market quotations and/or price quotations obtained from broker-dealers that may trade in the portfolio securities held by the Fund. The quotations of certain Fund holdings may not be updated during U.S. trading hours if such holdings do not trade in the United States. The Fund is not involved in, or responsible for, the calculation or dissemination of the IOPV and makes no representation or warranty as to its accuracy.

Determination of Net Asset Value. The NAV of the Fund normally is determined once daily Monday through Friday, generally as of the regularly scheduled close of business of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m., Eastern time) on each day that the NYSE is open for trading, based on prices at the time of closing provided that (a) any Fund assets or liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers (as detailed below) and (b) U.S. fixed income assets may be valued as of the announced closing time for trading in fixed income instruments in a particular market or exchange. The NAV of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets held by the Fund, and its liabilities, are determined pursuant to valuation policies and procedures approved by the Board. The Fund’s assets and liabilities are valued primarily on the basis of market quotations.

Equity investments are valued at market value, which is generally determined using the last reported official closing price or last trading price on the exchange or market on which the security is primarily traded at the time of valuation.

The Fund invests in foreign securities. Foreign currency exchange rates are generally determined as of 4:00 p.m., London time. Foreign securities owned by the Fund may trade on weekends or other days when the Fund does not price its shares. As a result,

the Fund’s NAV may change on days when Authorized Participants will not be able to purchase or redeem Fund shares.

Generally, trading in foreign securities, U.S. government securities, money market instruments and certain fixed-income securities is substantially completed each day at various times prior to the close of business on the NYSE. The values of such securities used in computing the NAV of the Fund are determined as of such times.

When market quotations are not readily available or are believed by BFA to be unreliable, the Fund’s investments are valued at fair value. Fair value determinations are made by BFA in accordance with policies and procedures approved by the Fund’s Board. BFA may conclude that a market quotation is not readily available or is unreliable if a security or other asset or liability does not have a price source due to its lack of liquidity, if a market quotation differs significantly from recent price quotations or otherwise no longer appears to reflect fair value, where the security or other asset or liability is thinly traded, or where there is a significant event subsequent to the most recent market quotation. A “significant event” is an event that, in the judgment of BFA, is likely to cause a material change to the closing market price of the asset or liability held by the Fund. Foreign securities whose values are affected by volatility that occurs in U.S. markets on a trading day after the close of foreign securities markets may be fair valued.

Fair value represents a good faith approximation of the value of an asset or liability. The fair value of an asset or liability held by the Fund is the amount the Fund might reasonably expect to receive from the current sale of that asset or the cost to extinguish that liability in an arm’s-length transaction. Valuing the Fund’s investments using fair value pricing will result in prices that may differ from current market valuations and that may not be the price at which those investments could have been sold during the period in which the particular fair values were used. Use of fair value prices and certain current market valuations could result in a difference between the prices used to calculate the Fund’s NAV and the prices used by the Underlying Index, which, in turn, could result in a difference between the Fund’s performance and the performance of the Underlying Index.

The value of assets or liabilities denominated in non-U.S. currencies will be converted into U.S. dollars using exchange rates deemed appropriate by BFA as investment adviser. Use of a rate different from the rate used by the Index Provider may adversely affect the Fund’s ability to track the Underlying Index.

Dividends and Distributions

General Policies. Dividends from net investment income, if any, generally are declared and paid semi-annually by the Fund. Distributions of net realized securities gains, if any, generally are declared and paid once a year, but the Trust may make distributions on a more frequent basis for the Fund. The Trust reserves the right to declare special distributions if, in its reasonable discretion, such action is necessary or advisable to preserve its status as a regulated investment company (“RIC”) or to avoid imposition of income or excise taxes on undistributed income or realized gains.

Dividends and other distributions on shares of the Fund are distributed on a pro rata basis to beneficial owners of such shares. Dividend payments are made through DTC

participants and indirect participants to beneficial owners then of record with proceeds received from the Fund.

Dividend Reinvestment Service. No dividend reinvestment service is provided by the Trust. Broker-dealers may make available the DTC book-entry Dividend Reinvestment Service for use by beneficial owners of the Fund for reinvestment of their dividend distributions. Beneficial owners should contact their broker to determine the availability and costs of the service and the details of participation therein. Brokers may require beneficial owners to adhere to specific procedures and timetables. If this service is available and used, dividend distributions of both income and realized gains will be automatically reinvested in additional whole shares of the Fund purchased in the secondary market.

Taxes. As with any investment, you should consider how your investment in shares of the Fund will be taxed. The tax information in this Prospectus is provided as general information, based on current law. You should consult your own tax professional about the tax consequences of an investment in shares of the Fund.

Unless your investment in Fund shares is made through a tax-exempt entity or tax-deferred retirement account, such as an IRA, you need to be aware of the possible tax consequences when the Fund makes distributions or you sell Fund shares.

Taxes on Distributions. Distributions from the Fund’s net investment income (other than qualified dividend income), including distributions of income from securities lending and distributions out of the Fund’s net short-term capital gains, if any, are taxable to you as ordinary income. Distributions by the Fund of net long-term capital gains in excess of net short-term capital losses (capital gain dividends) are taxable to you as long-term capital gains, generally at a 15% tax rate (0% at certain income levels), regardless of how long you have held the Fund’s shares. Distributions by the Fund that qualify as qualified dividend income are taxable to you at long-term capital gain rates for taxable years beginning on or before December 31, 2012. The 15% and 0% tax rates expire for taxable years beginning after December 31, 2012. Maximum long-term capital gain income tax rates are scheduled to rise to 20% in 2013. Beginning in 2013, a 3.8% U.S. federal Medicare contribution tax will be imposed on “net investment income,” including interest, dividends, and capital gains, of U.S. individuals with income exceeding $200,000 (or $250,000 if married and filing jointly), and of estates and trusts.

Dividends will be qualified dividend income to you if they are attributable to qualified dividend income received by the Fund. Generally, qualified dividend income includes dividend income from taxable U.S. corporations and qualified non-U.S. corporations, provided that the Fund satisfies certain holding period requirements in respect of the stock of such corporations and has not hedged its position in the stock in certain ways. Substitute dividends received by the Fund with respect to dividends paid on securities lent out will not be qualified dividend income. For this purpose, a qualified non-U.S. corporation means any non-U.S. corporation that is eligible for benefits under a comprehensive income tax treaty with the United States, which includes an exchange of information program or if the stock with respect to which the dividend was paid is readily tradable on an established United States securities market. The term excludes a corporation that is a passive foreign investment company.

Dividends received by the Fund from a real estate investment trust (“REIT”) or another RIC generally are qualified dividend income only to the extent the dividend distributions are made out of qualified dividend income received by such REIT or RIC. It is expected that dividends received by the Fund from a REIT and distributed to a shareholder generally will be taxable to the shareholder as ordinary income.

For a dividend to be treated as qualified dividend income, the dividend must be received with respect to a share of stock held without being hedged by the Fund, and with respect to a share of the Fund held without being hedged by you, for 61 days during the 121-day period beginning at the date which is 60 days before the date on which such share becomes ex-dividend with respect to such dividend or, in the case of certain preferred stock, 91 days during the 181-day period beginning 90 days before such date.

If your Fund shares are loaned out pursuant to a securities lending arrangement, you may lose the ability to use foreign tax credits passed through by the Fund or to treat Fund dividends paid while the shares are held by the borrower as qualified dividend income.

In general, your distributions are subject to U.S. federal income tax for the year when they are paid. Certain distributions paid in January, however, may be treated as paid on December 31 of the prior year.

If the Fund’s distributions exceed current and accumulated earnings and profits, all or a portion of the distributions made in the taxable year may be recharacterized as a return of capital to shareholders. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and result in a higher capital gain or lower capital loss when those shares on which the distribution was received are sold. Once a shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain, if the shareholder holds shares of the Fund as capital assets.

If you are neither a resident nor a citizen of the United States or if you are a non-U.S. entity, the Fund’s ordinary income dividends (which include distributions of net short-term capital gains) will generally be subject to a 30% U.S. withholding tax, unless a lower treaty rate applies, provided that withholding tax will generally not apply to any gain or income realized by a non-U.S. shareholder in respect of any distributions of long-term capital gains or upon the sale or other disposition of shares of the Fund.

A 30% withholding tax will be imposed on dividends paid after December 31, 2013, and redemption proceeds paid after December 31, 2014, to (i) foreign financial institutions including non-U.S. investment funds unless they agree to collect and disclose to the Internal Revenue Service (“IRS”) information regarding their direct and indirect U.S. account holders and (ii) certain other foreign entities, unless they certify certain information regarding their direct and indirect U.S. owners. To avoid withholding, foreign financial institutions will need to enter into agreements with the IRS that state that they will provide the IRS information, including the name, address and taxpayer identification number of direct and indirect U.S. account holders, comply with due diligence procedures with respect to the identification of U.S. accounts, report to the IRS certain information with respect to U.S. accounts maintained, agree to withhold tax on certain payments made to non-compliant foreign financial institutions or to

account holders who fail to provide the required information, and determine certain other information as to their account holders. Other foreign entities will need to provide the name, address, and taxpayer identification number of each substantial U.S. owner or certifications of no substantial U.S. ownership unless certain exceptions apply.

Dividends, interest and capital gains earned by the Fund with respect to non-U.S. securities may give rise to withholding and other taxes imposed by non-U.S. countries. Tax conventions between certain countries and the United States may reduce or eliminate such taxes. If more than 50% of the total assets of the Fund at the close of a year consists of non-U.S. stocks or securities, the Fund may “pass through” to you certain non-U.S. income taxes (including withholding taxes) paid by the Fund. This means that you would be considered to have received as an additional dividend your share of such non-U.S. taxes, but you may be entitled to either a corresponding tax deduction in calculating your taxable income, or, subject to certain limitations, a credit in calculating your U.S. federal income tax.

For purposes of foreign tax credits for U.S. shareholders of the Fund, foreign capital gains taxes may not produce associated foreign source income, thereby limiting a U.S. person’s ability to use such credits.

If you are a resident or a citizen of the United States, by law, back-up withholding will apply to your distributions and proceeds if you have not provided a taxpayer identification number or social security number and made other required certifications.

Taxes When Shares are Sold. Currently, any capital gain or loss realized upon a sale of Fund shares is generally treated as a long-term gain or loss if the shares have been held for more than one year. Any capital gain or loss realized upon a sale of Fund shares held for one year or less is generally treated as short-term gain or loss, except that any capital loss on the sale of shares held for six months or less is treated as long-term capital loss to the extent that capital gain dividends were paid with respect to such shares. Beginning in 2013, any such capital gains, including from sales of Fund shares or from capital gain dividends, will be included in “net investment income” for purposes of the 3.8% U.S. federal Medicare contribution tax mentioned above.

The foregoing discussion summarizes some of the consequences under current U.S. federal tax law of an investment in the Fund. It is not a substitute for personal tax advice. You may also be subject to state and local taxation on Fund distributions and sales of shares. Consult your personal tax adviser about the potential tax consequences of an investment in shares of the Fund under all applicable tax laws.

Creations and Redemptions. Prior to trading in the secondary market, shares of the Fund are “created” at NAV by market makers, large investors and institutions only in block-size Creation Units of 400,000 shares or multiples thereof. Each “creator” or “Authorized Participant” enters into an authorized participant agreement with the Fund’s distributor, SEI Investments Distribution Co. (the “Distributor”). Only an Authorized Participant may create or redeem Creation Units directly with the Fund. A creation transaction, which is subject to acceptance by the transfer agent, generally takes place when an Authorized Participant deposits into the Fund a designated portfolio of securities and a specified amount of cash approximating the holdings of

the Fund in exchange for a specified number of Creation Units. To the extent practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund.

Similarly, shares can be redeemed only in Creation Units, generally for a designated portfolio of securities and a specified amount of cash held by the Fund (“Fund Securities”). Except when aggregated in Creation Units, shares are not redeemable by the Fund. The prices at which creations and redemptions occur are based on the next calculation of NAV after an order is received in a form described in the authorized participant agreement.

The Fund intends to comply with the U.S. federal securities laws in accepting securities for deposit and satisfying redemptions with redemption securities by, among other means, assuring that any securities accepted for deposit and any securities used to satisfy redemption requests will be sold in transactions that would be exempt from registration under the Securities Act of 1933, as amended (the “1933 Act”). Further, an Authorized Participant that is not a “qualified institutional buyer,” as such term is defined under Rule 144A of the 1933 Act, will not be able to receive Fund Securities that are restricted securities eligible for resale under Rule 144A.

Creations and redemptions must be made through a firm that is either a member of the Continuous Net Settlement System of the National Securities Clearing Corporation or a DTC participant and has executed an agreement with the Distributor with respect to creations and redemptions of Creation Unit aggregations. Information about the procedures regarding creation and redemption of Creation Units (including the cut-off times for receipt of creation and redemption orders) is included in the Fund’s SAI.

Because new shares may be created and issued on an ongoing basis, at any point during the life of the Fund a “distribution,” as such term is used in the 1933 Act, may be occurring. Broker-dealers and other persons are cautioned that some activities on their part may, depending on the circumstances, result in their being deemed participants in a distribution in a manner that could render them statutory underwriters and subject to the prospectus delivery and liability provisions of the 1933 Act. Any determination of whether one is an underwriter must take into account all the relevant facts and circumstances of each particular case.

Broker-dealers should also note that dealers who are not “underwriters” but are participating in a distribution (as contrasted to ordinary secondary transactions), and thus dealing with shares that are part of an “unsold allotment” within the meaning of Section 4(3)(C) of the 1933 Act, would be unable to take advantage of the prospectus delivery exemption provided by Section 4(3) of the 1933 Act. For delivery of prospectuses to exchange members, the prospectus delivery mechanism of Rule 153 under the 1933 Act is available only with respect to transactions on a national securities exchange.

Costs Associated with Creations and Redemptions. Authorized Participants are charged standard creation and redemption transaction fees to offset transfer and other transaction costs associated with the issuance and redemption of Creation Units. The standard creation and redemption transaction fees are set forth in the table below. The standard creation transaction fee is charged to the Authorized Participant

on the day such Authorized Participant creates a Creation Unit, and is the same regardless of the number of Creation Units purchased by the Authorized Participant on the applicable business day. Similarly, the standard redemption transaction fee is charged to the Authorized Participant on the day such Authorized Participant redeems a Creation Unit, and is the same regardless of the number of Creation Units redeemed by the Authorized Participant on the applicable business day. Creations and redemptions for cash (when cash creations and redemptions (in whole or in part) are available or specified) are also subject to an additional charge (up to the maximum amounts shown in the table below). This charge is intended to compensate for brokerage, tax, foreign exchange, execution, market impact and other costs and expenses related to cash transactions. Investors who use the services of a broker or other financial intermediary may pay fees for such services.

The following table shows, as of September 30, 2011, the approximate value of one Creation Unit, standard fees and maximum additional charges for creations and redemptions (as described above):

Householding. Householding is an option available to certain Fund investors. Householding is a method of delivery, based on the preference of the individual investor, in which a single copy of certain shareholder documents can be delivered to investors who share the same address, even if their accounts are registered under different names. Please contact your broker-dealer if you are interested in enrolling in householding and receiving a single copy of prospectuses and other shareholder documents, or if you are currently enrolled in householding and wish to change your householding status.

Distribution

The Distributor distributes Creation Units for the Fund on an agency basis. The Distributor does not maintain a secondary market in shares of the Fund. The Distributor has no role in determining the policies of the Fund or the securities that are purchased or sold by the Fund. The Distributor’s principal address is One Freedom Valley Drive, Oaks, PA 19456.

In addition, BFA or its Affiliates make payments to broker-dealers, banks or other financial intermediaries (together, “intermediaries”) related to marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems, or their making shares of the Fund and certain other iShares funds available to their customers. Such payments, which may be significant to the intermediary, are not made by the Fund. Rather, such payments are

made by BFA or its Affiliates from their own resources, which come directly or indirectly in part from fees paid by the iShares funds complex. Payments of this type are sometimes referred to as revenue-sharing payments. A financial intermediary may make decisions about which investment options it recommends or makes available, or the level of services provided, to its customers based on the revenue-sharing payments it is eligible to receive. Therefore, such payments to an intermediary create conflicts of interest between the intermediary and its customers and may cause the intermediary to recommend the Fund or other iShares funds over another investment. More information regarding these payments is contained in the Fund’s SAI. Please contact your salesperson or other investment professional for more information regarding any such payments his or her firm may receive from BFA or its Affiliates.

Financial Highlights

The financial highlights table is intended to help investors understand the Fund’s financial performance for the past five years. Certain information reflects financial results for a single share of the Fund. The total returns in the table represent the rate that an investor would have earned (or lost) on an investment in the Fund, assuming reinvestment of all dividends and distributions. This information has been audited by PricewaterhouseCoopers LLP, whose report is included, along with the Fund’s financial statements, in the Fund’s Annual Report (available upon request).

Supplemental Information

I. Premium/Discount Information

The table that follows presents information about the differences between the daily market price on secondary markets for shares of the Fund and the Fund’s NAV. NAV is the price at which the Fund issues and redeems shares. It is calculated in accordance with the standard formula for valuing mutual fund shares. The price used to calculate market returns (“Market Price”) of the Fund generally is determined using the midpoint between the highest bid and the lowest offer on the primary securities exchange on which shares of the Fund are listed for trading, as of the time that the Fund’s NAV is calculated. The Fund’s Market Price may be at, above or below its NAV. The NAV of the Fund will fluctuate with changes in the value of its portfolio holdings. The Market Price of the Fund will fluctuate in accordance with changes in its NAV, as well as market supply and demand.

Premiums or discounts are the differences (expressed as a percentage) between the NAV and Market Price of the Fund on a given day, generally at the time the NAV is calculated. A premium is the amount that the Fund is trading above the reported NAV, expressed as a percentage of the NAV. A discount is the amount that the Fund is trading below the reported NAV, expressed as a percentage of the NAV.

The following information shows the frequency of distributions of premiums and discounts for the Fund for each full calendar quarter of 2010 through September 30, 2011.

Each line in the table shows the number of trading days in which the Fund traded within the premium/discount range indicated. The number of trading days in each premium/discount range is also shown as a percentage of the total number of trading days in the period covered by the table. All data presented here represents past performance, which cannot be used to predict future results.

II. Total Return Information

The tables that follow present information about the total returns of the Fund and the Underlying Index as of the fiscal year ended July 31, 2011.

“Average Annual Total Returns” represent the average annual change in value of an investment over the periods indicated. “Cumulative Total Returns” represent the total change in value of an investment over the period indicated.

The Fund’s NAV is the value of one share of the Fund as calculated in accordance with the standard formula for valuing mutual fund shares. The NAV return is based on the NAV of the Fund and the market return is based on the Market Price of the Fund. Market Price is determined by using the midpoint between the highest bid and the lowest offer on the primary stock exchange on which shares of the Fund are listed for trading, as of the time that the Fund’s NAV is calculated. Since shares of the Fund did not trade in the secondary market until after the Fund’s inception, for the period from inception to the first day of secondary market trading in shares of the Fund, the NAV of the Fund is used as a proxy for the Market Price to calculate market returns. Market and NAV returns assume that dividends and capital gain distributions have been reinvested in the Fund at Market Price and NAV, respectively.

An index is a statistical composite that tracks a specified financial market or sector. Unlike the Fund, the Underlying Index does not actually hold a portfolio of securities and therefore does not incur the expenses incurred by the Fund. These expenses negatively impact the performance of the Fund. Also, market returns do not include brokerage commissions that may be payable on secondary market transactions. If brokerage commissions were included, market returns would be lower. The returns shown in the following table do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption or sale of Fund shares. The investment return and principal value of shares of the Fund will vary with changes in market conditions. Shares of the Fund may be worth more or less than their original cost when they are redeemed or sold in the market. The Fund’s past performance is no guarantee of future results.

Fund Overview

iSHARES® MSCI EAFE INDEX FUND

Ticker: EFA Stock Exchange: NYSE Arca

Investment Objective

The iShares MSCI EAFE Index Fund (the “Fund”) seeks investment results that correspond generally to the price and yield performance, before fees and expenses, of the MSCI EAFE® Index (the “Underlying Index”).

Fees and Expenses

The following table describes the fees and expenses that you will incur if you own shares of the Fund. The investment advisory agreement between iShares Trust (the “Trust”) and BlackRock Fund Advisors (“BFA”) (the “Investment Advisory Agreement”) provides that BFA will pay all operating expenses of the Fund, except interest expenses, taxes, brokerage expenses, future distribution fees or expenses, and extraordinary expenses.

You may also incur usual and customary brokerage commissions when buying or selling shares of the Fund, which are not reflected in the example that follows:

Example. This Example is intended to help you compare the cost of owning shares of the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

Portfolio Turnover. The Fund may pay transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 6% of the average value of its portfolio.

Principal Investment Strategies

The Underlying Index has been developed by MSCI as an equity benchmark for its international stock performance. The Underlying Index includes stocks from Europe, Australasia and the Far East and, as of September 30, 2011, consisted of the following 22 developed market country indexes or regions: Australia, Austria, Belgium, Denmark, Finland, France, Germany, Greece, Hong Kong, Ireland, Israel, Italy, Japan, the Netherlands, New Zealand, Norway, Portugal, Singapore, Spain, Sweden, Switzerland and the United Kingdom.

BFA uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to “beat” the index it tracks and does not seek temporary defensive positions when markets decline or appear overvalued.

Indexing may eliminate the chance that the Fund will substantially outperform the Underlying Index but also may reduce some of the risks of active management, such as poor security selection. Indexing seeks to achieve lower costs and better after-tax performance by keeping portfolio turnover low in comparison to actively managed investment companies.

BFA uses a representative sampling indexing strategy to manage the Fund. “Representative sampling” is an indexing strategy that involves investing in a representative sample of securities that collectively has an investment profile similar to the Underlying Index. The securities selected are expected to have, in the aggregate, investment characteristics (based on factors such as market capitalization and industry weightings), fundamental characteristics (such as return variability and yield) and liquidity measures similar to those of the Underlying Index. The Fund may or may not hold all of the securities in the Underlying Index.

The Fund generally invests at least 90% of its assets in securities of the Underlying Index and in depositary receipts representing securities of the Underlying Index. The Fund may invest the remainder of its assets in securities not included in the Underlying Index, but which BFA believes will help the Fund track the Underlying Index and in other investments including futures contracts, options on futures contracts, options and swaps as well as cash and cash equivalents, including shares of money market funds advised by BFA or its affiliates.

The Fund may lend securities representing up to one-third of the value of the Fund’s total assets (including the value of the collateral received).

The Underlying Index is sponsored by an organization (the “Index Provider”) that

S-2   


Table Of Contents



is independent of the Fund and BFA. The Index Provider determines the composition and relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index. The Fund’s Index Provider is MSCI Inc. (“MSCI”).

Industry Concentration Policy. The Fund will concentrate its investments (i.e., hold 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. For purposes of this limitation, securities of the U.S. government (including its agencies and instrumentalities) and repurchase agreements collateralized by U.S. government securities are not considered to be issued by members of any industry.

Summary of Principal Risks

As with any investment, you could lose all or part of your investment in the Fund, and the Fund’s performance could trail that of other investments. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund’s net asset value per share (“NAV”), trading price, yield, total return and ability to meet its investment objective.

Asset Class Risk. Securities in the Underlying Index or in the Fund’s portfolio may underperform in comparison to the general securities markets or other asset classes.

Concentration Risk. To the extent that the Fund’s investments are concentrated in a particular issuer, region, country, market, industry or asset class, the Fund may be susceptible to loss due to adverse occurrences affecting that issuer, region, country, market, industry or asset class.

Consumer Staples Sector Risk. The consumer staples sector may be affected by marketing campaigns, changes in consumer demands, government regulations and changes in commodity prices.

Currency Risk. Because the Fund’s NAV is determined in U.S. dollars, the Fund’s NAV could decline if the currency of a non-U.S. market in which the Fund invests depreciates against the U.S. dollar.

Equity Securities Risk. Equity securities are subject to changes in value and their values may be more volatile than other asset classes.

Financial Sector Risk. Performance of companies in the financial sector may be adversely impacted by many factors, including, among others, government regulations, economic conditions, credit rating downgrades, changes in interest rates, and decreased liquidity in credit markets. This sector has experienced significant losses in the recent past, and the impact of more stringent capital requirements and of recent or future regulation on any individual financial company or on the sector as a whole cannot be predicted.

Geographic Risk. A natural or other disaster could occur in a geographic region in which the Fund invests, which could affect the economy or particular business operations of companies in the specific geographic region, causing an adverse impact on the Fund’s investments in the affected region.

Industrials Sector Risk. The industrials sector is affected by changes in the supply and demand for products and

S-3   


Table Of Contents



services, product obsolescence, claims for environmental damage or product liability and general economic conditions, among other factors.

Issuer Risk. Fund performance depends on the performance of individual securities to which the Fund has exposure. Changes to the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA’s investment management strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares, losses from trading in secondary markets, periods of high volatility and disruption in the creation/redemption process of the Fund. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV.

Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers are subject to the risks associated with investing in those non-U.S. markets, such as heightened risks of inflation or nationalization. The Fund may lose money due to political, economic and geographic events affecting a non-U.S. issuer or market. The Fund is specifically exposed to Asian Economic Risk and European Economic Risk.

Passive Investment Risk. The Fund is not actively managed and BFA does not attempt to take defensive positions under any market conditions, including declining markets.

Privatization Risk. Some countries in which the Fund invests have begun a process of privatizing certain entities and industries. Privatized entities may lose money or be re-nationalized.

Risk of Investing in Japan. The Japanese economy may be subject to considerable degrees of economic, political and social instability, which could have a negative impact on Japanese securities.

Risk of Investing in the United Kingdom. The Fund’s investment in British issuers may subject the Fund to regulatory, political, currency, security, and economic risk specific to the United Kingdom. The United Kingdom has one of the largest economies in Europe, and the United States and other European countries are substantial trading partners of the United Kingdom. As a result, the British economy may be impacted by changes to the economic health of the United States and other European countries. The British economy, along with certain other European economies, experienced a significant economic slowdown during the recent financial crisis; certain British financial institutions were severely under-capitalized and required government intervention to survive.

Securities Lending Risk. The Fund may engage in securities lending. Securities lending involves the risk that the Fund may lose money because the borrower of the Fund’s loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the

S-4   


Table Of Contents



value of the collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Security Risk. Some countries and regions in which the Fund invests have experienced security concerns. Incidents involving a country’s or region’s security may cause uncertainty in these markets and may adversely affect their economies and the Fund’s investments.

Tracking Error Risk. The performance of the Fund may diverge from that of the Underlying Index. Because the Fund employs a representative sampling strategy, the Fund may experience tracking error to a greater extent than a fund that seeks to replicate an index.

Valuation Risk. The value of the securities in the Fund’s portfolio may change on days when shareholders will not be able to purchase or sell the Fund’s shares.

Performance Information

The bar chart and table that follow show how the Fund has performed on a calendar year basis and provide an indication of the risks of investing in the Fund. Both assume that all dividends and distributions have been reinvested in the Fund. Past performance (before and after taxes) does not necessarily indicate how the Fund will perform in the future. Supplemental information about the Fund’s performance is shown under the heading Total Return Information in the Supplemental Information section of the Fund’s prospectus (the “Prospectus”).

Year by Year Returns1 (Years Ended December 31)


1 The Fund’s total return for the nine months ended September 30, 2011 was -14.92%.

The best calendar quarter return during the periods shown above was 25.45% in the 2nd quarter of 2009; the worst was
-20.51% in the 3rd quarter of 2008.

1 After-tax returns in the table above are calculated using the historical highest individual U.S. federal marginal income tax rates and do not reflect the impact of state or local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown, and after-tax returns shown are not relevant to tax-exempt investors or investors who hold shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts (“IRAs”). Fund returns after taxes on distributions and sale of Fund shares are calculated assuming that an investor has sufficient capital gains of the same character from other investments to offset any capital losses from the sale of Fund shares. As a result, Fund returns after taxes on distributions and sale of Fund shares may exceed Fund returns before taxes and/or returns after taxes on distributions.

Management

Investment Adviser. BlackRock Fund Advisors.

Portfolio Managers. Rene Casis, Diane Hsiung and Greg Savage (the “Portfolio Managers”) are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager supervises a portfolio management team. Mr. Casis, Ms. Hsiung and Mr. Savage have been Portfolio Managers of the Fund since 2010, 2008 and 2008, respectively.

Purchase and Sale of Fund Shares

The Fund is an exchange-traded fund (commonly referred to as an “ETF”). Individual Fund shares may only be purchased and sold on a national securities exchange through a broker-dealer. The price of Fund shares is based on market price, and because ETF shares trade at market prices rather than NAV, shares may trade at a price greater than NAV (a premium) or less than NAV (a discount). The Fund will only issue or redeem shares that have been aggregated into blocks of 600,000 shares or multiples thereof (“Creation Units”) to authorized participants who have entered into agreements with the Fund’s distributor. The Fund generally will issue or redeem Creation Units in return for a designated portfolio of securities (and an amount of cash) that the Fund specifies each day.

Tax Information

The Fund intends to make distributions that may be taxable to you as ordinary income or capital gains, unless you are investing through a tax-deferred arrangement such as a 401(k) plan or an IRA.

Payments to Broker-Dealers and other Financial Intermediaries

If you purchase shares of the Fund through a broker-dealer or other financial intermediary (such as a bank), BFA or other related companies may pay the intermediary for marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems or other services related to the sale or promotion of the Fund. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.

More Information About the Fund

This Prospectus contains important information about investing in the Fund. Please read this Prospectus carefully before you make any investment decisions. Additional information regarding the Fund is available at www.iShares.com.

BFA is the investment adviser to the Fund. Shares of the Fund are listed for trading on NYSE Arca, Inc. (“NYSE Arca”). The market price for a share of the Fund may be different from the Fund’s most recent NAV.

ETFs are funds that trade like other publicly-traded securities. The Fund is designed to track an index. Similar to shares of an index mutual fund, each share of the Fund represents a partial ownership in an underlying portfolio of securities intended to track a market index. Unlike shares of a mutual fund, which can be bought and redeemed from the issuing fund by all shareholders at a price based on NAV, shares of the Fund may be purchased or redeemed directly from the Fund at NAV solely by authorized participants. Also unlike shares of a mutual fund, shares of the Fund are listed on a national securities exchange and trade in the secondary market at market prices that change throughout the day.

The Fund invests in a particular segment of the securities markets and seeks to track the performance of a securities index that generally is not representative of the market as a whole. The Fund is designed to be used as part of broader asset allocation strategies. Accordingly, an investment in the Fund should not constitute a complete investment program.

An index is a theoretical financial calculation while the Fund is an actual investment portfolio. The performance of the Fund and the Underlying Index may vary due to transaction costs, non-U.S. currency valuations, asset valuations, corporate actions (such as mergers and spin-offs), timing variances and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions (such as diversification requirements) that apply to the Fund but not to the Underlying Index or to the use of representative sampling. “Tracking error” is the difference between the performance (return) of the Fund’s portfolio and that of the Underlying Index. BFA expects that, over time, the Fund’s tracking error will not exceed 5%. Because the Fund uses a representative sampling indexing strategy, it can be expected to have a larger tracking error than if it used a replication indexing strategy. “Replication” is an indexing strategy in which a fund invests in substantially all of the securities in its underlying index in approximately the same proportions as in the underlying index.

An investment in the Fund is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, BFA or any of its affiliates.

The Fund’s investment objective and the Underlying Index may be changed without shareholder approval.

A Further Discussion of Principal Risks

The Fund is subject to various risks, including the principal risks noted below, any of which may adversely affect the Fund’s NAV, trading price, yield, total return and ability to meet its investment objective. You could lose all or part of your investment in the Fund, and the Fund could underperform other investments.

Asian Economic Risk. Certain Asian economies have experienced over-extension of credit, currency devaluations and restrictions, high unemployment, high inflation, decreased exports and economic recessions. Economic events in any one Asian country may have a significant economic effect on the entire Asian region, as well as on major trading partners outside Asia, and any adverse event in the Asian markets may have a significant adverse effect on other Asian economies.

Asset Class Risk. The securities in the Underlying Index or in the Fund’s portfolio may underperform the returns of other securities or indexes that track other countries, groups of countries, regions, industries, groups of industries, markets, asset classes or sectors. Various types of securities or indexes tend to experience cycles of outperformance and underperformance in comparison to the general securities markets.

Concentration Risk. To the extent that the Fund’s portfolio reflects the Underlying Index’s concentration in the securities of a particular issuer or issuers in a particular country, group of countries, region, market, industry, group of industries, sector or asset class, the Fund may be adversely affected by the performance of those securities, may be subject to increased price volatility and may be more susceptible to adverse economic, market, political or regulatory occurrences affecting that issuer, country, group of countries, region, market, industry, group of industries, sector or asset class.

Consumer Staples Sector Risk. The Fund invests in companies in the consumer staples sector. The consumer staples sector may be affected by the permissibility of using various food additives and production methods, marketing campaigns and other factors affecting consumer demand. Tobacco companies, in particular, may be adversely affected by new laws, regulations and litigation. The consumer staples sector may also be adversely affected by changes or trends in commodity prices, which may be influenced or characterized by unpredictable factors.

Currency Risk. Because the Fund’s NAV is determined on the basis of the U.S. dollar, investors may lose money if the currency of a non-U.S. market in which the Fund invests depreciates against the U.S. dollar, even if the local currency value of the Fund’s holdings in that market increases.

Equity Securities Risk. The Fund invests in equity securities, which are subject to changes in value that may be attributable to market perception of a particular issuer or to general stock market fluctuations that affect all issuers. Investments in equity securities may be more volatile than investments in other asset classes.

European Economic Risk. The Economic and Monetary Union of the European Union (the “EU”) requires member countries to comply with restrictions on inflation rates, deficits, interest rates, debt levels and fiscal and monetary controls, each of which may

significantly affect every country in Europe. Decreasing imports or exports, changes in governmental or EU regulations on trade, changes in the exchange rate of the euro, the default or threat of default by an EU member country on its sovereign debt, and/or an economic recession in an EU member country may have a significant adverse effect on the economies of EU member countries and on major trading partners outside Europe. The European financial markets have recently experienced volatility and have been adversely affected by concerns about economic downturns, credit rating downgrades, rising government debt levels and possible default on or restructuring of government debt in several European countries, including Greece, Ireland, Italy, Portugal and Spain. A default or debt restructuring by any European country would adversely impact holders of that country’s debt, and sellers of credit default swaps linked to that country’s creditworthiness, which may be located in countries other than those listed in the previous sentence. These events have adversely affected the value and exchange rate of the euro and may continue to significantly affect the economies of every country in Europe, including EU member countries that do not use the euro and non-EU member countries.

Financial Sector Risk. Companies in the financial sector of an economy are often subject to governmental regulation and, recently, government intervention and the potential for additional regulation, which may adversely affect the scope of their activities, the prices they can charge and the amount of capital they must maintain. Governmental regulation may change frequently and may have significant adverse consequences for companies in the financial sector, including effects not intended by such regulation. The impact of recent or future regulation in various countries on any individual financial company or on the sector as a whole cannot be predicted. Certain risks may impact the value of investments in the financial sector more severely than investments outside this sector, including the risks associated with companies that operate with substantial financial leverage. Companies in the financial sector may also be adversely affected by increases in interest rates and loan losses, decreases in the availability of money or asset valuations, credit rating downgrades and adverse conditions in other related markets. Over the past few years, the deterioration of the credit markets has impacted a broad range of mortgage, asset-backed, auction rate, sovereign debt and other markets, including U.S. and non-U.S. credit and interbank money markets, thereby affecting a wide range of financial institutions and markets. This situation has created instability in the financial markets and caused certain financial companies to incur large losses. Some financial companies have experienced declines in the valuations of their assets, taken actions to raise capital (such as the issuance of debt or equity securities), or even ceased operations. Some financial companies have borrowed significant amounts of capital from governments and may face future government-imposed restrictions on their businesses or increased government intervention. These actions have caused the securities of many financial companies to decline in value. Insurance companies, in particular, may be subject to severe price competition, which may have an adverse impact on their profitability.

Geographic Risk. Some markets in which the Fund invests are located in parts of the world that have historically been prone to natural disasters, such as earthquakes, volcanoes, droughts, floods, hurricanes and tsunamis, and are economically sensitive to environmental events. Any natural or other disaster could have a significant adverse

impact on the economies of these geographic areas, causing an adverse impact on the Fund’s investments in the affected region.

Industrials Sector Risk. The stock prices of companies in the industrials sector are affected by supply and demand, both for their specific product or service and for industrials sector products in general. The products of manufacturing companies may face obsolescence due to rapid technological developments and frequent new product introduction. Government regulations, world events, economic conditions and exchange rates affect the performance of companies in the industrials sector. Companies in the industrials sector may be adversely affected by liability for environmental damage, product liability claims and exchange rates. The industrials sector may also be adversely affected by changes or trends in commodity prices, which may be influenced by unpredictable factors.

Issuer Risk. The performance of the Fund depends on the performance of individual securities to which the Fund has exposure. Any issuer of these securities may perform poorly, causing the value of its securities to decline. Poor performance may be caused by poor management decisions, competitive pressures, changes in technology, expiration of patent protection, disruptions in supply, labor problems or shortages, corporate restructurings, fraudulent disclosures or other factors. Issuers may, in times of distress or at their own discretion, decide to reduce or eliminate dividends, which may also cause their stock prices to decline.

Management Risk. The Fund may not fully replicate the Underlying Index and may hold securities not included in the Underlying Index. As a result, the Fund is subject to the risk that BFA’s investment management strategy, the implementation of which is subject to a number of constraints, may not produce the intended results.

Market Risk. The Fund could lose money due to short-term market movements and over longer periods during market downturns. Securities may decline in value due to factors affecting securities markets generally or particular industries represented in the markets. The value of a security may decline due to general market conditions, economic trends or events that are not specifically related to the issuer of the security or to factors that affect a particular industry or industries. During a general downturn in the securities markets, multiple asset classes may be negatively affected.

Market Trading Risk

Absence of Active Market. Although shares of the Fund are listed for trading on one or more stock exchanges, there can be no assurance that an active trading market for such shares will develop or be maintained.

Risk of Secondary Listings. The Fund’s shares may be listed or traded on U.S. and non-U.S. stock exchanges other than the U.S. stock exchange where the Fund’s primary listing is maintained. There can be no assurance that the Fund’s shares will continue to trade on any such stock exchange or in any market or that the Fund’s shares will continue to meet the requirements for listing or trading on any exchange or in any market. The Fund’s shares may be less actively traded in certain markets than others, and investors are subject to the execution and settlement risks and market standards of the market where they or their broker direct their trades for execution. Certain information available to investors who trade Fund shares on a U.S. stock exchange

during regular U.S. market hours may not be available to investors who trade in other markets, which may result in secondary market prices in such markets being less efficient.

Secondary Market Trading Risk. Shares of the Fund may trade in the secondary market at times when the Fund does not accept orders to purchase or redeem shares. At such times, shares may trade in the secondary market with more significant premiums or discounts than might be experienced at times when the Fund accepts purchase and redemption orders.

Secondary market trading in Fund shares may be halted by a stock exchange because of market conditions or other reasons. In addition, trading in Fund shares on a stock exchange or in any market may be subject to trading halts caused by extraordinary market volatility pursuant to “circuit breaker” rules on the stock exchange or market. There can be no assurance that the requirements necessary to maintain the listing or trading of Fund shares will continue to be met or will remain unchanged.

Shares of the Fund May Trade at Prices Other Than NAV. Shares of the Fund trade on stock exchanges at prices at, above or below their most recent NAV. The NAV of the Fund is calculated at the end of each business day and fluctuates with changes in the market value of the Fund’s holdings since the most recent calculation. The trading prices of the Fund’s shares fluctuate continuously throughout trading hours based on market supply and demand rather than NAV. The trading prices of the Fund’s shares may deviate significantly from NAV during periods of market volatility. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV. However, because shares can be created and redeemed in Creation Units at NAV (unlike shares of many closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their NAVs), BFA believes that large discounts or premiums to the NAV of the Fund are not likely to be sustained over the long-term. While the creation/redemption feature is designed to make it likely that the Fund’s shares normally will trade on stock exchanges at prices close to the Fund’s next calculated NAV, exchange prices are not expected to correlate exactly with the Fund’s NAV due to timing reasons as well as market supply and demand factors. In addition, disruptions to creations and redemptions or extreme market volatility may result in trading prices for shares of the Fund that differ significantly from its NAV.

Costs of Buying or Selling Fund Shares. Buying or selling Fund shares on an exchange involves two types of costs that apply to all securities transactions. When buying or selling shares of the Fund through a broker, you will likely incur a brokerage commission or other charges imposed by brokers as determined by that broker. In addition, you may incur the cost of the “spread” – that is, the difference between what investors are willing to pay for Fund shares (the “bid” price) and the price at which they are willing to sell Fund shares (the “ask” price). Because of the costs inherent in buying or selling Fund shares, frequent trading may detract significantly from investment results and an investment in Fund shares may not be advisable for investors who anticipate regularly making small investments.

Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers are subject to all of the risks of investing in the markets where such issuers are located,

including heightened risks of inflation or nationalization and market fluctuations caused by economic and political developments. As a result of investing in non-U.S. securities, the Fund may be subject to increased risk of loss caused by any of the factors listed below:

  • Lower levels of liquidity and market efficiency;
  • Greater securities price volatility;
  • Exchange rate fluctuations and exchange controls;
  • Less availability of public information about issuers;
  • Limitations on foreign ownership of securities;
  • Imposition of withholding or other taxes;
  • Imposition of restrictions on the expatriation of the funds or other assets of the Fund;
  • Higher transaction and custody costs and delays in settlement procedures;
  • Difficulties in enforcing contractual obligations;
  • Lower levels of regulation of the securities market;
  • Weaker accounting, disclosure and reporting requirements; and
  • Legal principles related to corporate governance, directors’ fiduciary duties and liabilities and stockholders’ rights in markets in which the Fund invests may differ and/or may not be as extensive or protective as those that apply in the United States.

Passive Investment Risk. The Fund is not actively managed and may be affected by a general decline in market segments related to the Underlying Index. The Fund invests in securities included in, or representative of, the Underlying Index regardless of their investment merits. BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

Privatization Risk. Some countries in which the Fund invests have begun a process of privatizing certain entities and industries. In some instances, investors in newly privatized entities have suffered losses due to the inability of the newly privatized entities to adjust quickly to a competitive environment or changing regulatory and legal standards or, in some cases, due to re-nationalization of such privatized entities. There is no assurance that such losses will not recur.

Risk of Investing in Japan. Japan may be subject to political, economic, nuclear, and labor risks. Any of these risks, individually or in the aggregate, can impact an investment made in Japan.

  • Political Risk. Historically, Japan has had unpredictable national politics and may experience frequent political turnover. Future political developments may lead to changes in policy that might adversely affect the Fund’s investments.
  • Large Government Debt Risk. The Japanese economy faces several concerns, including a financial system with large levels of nonperforming loans, over-leveraged corporate balance sheets, extensive cross-ownership by major corporations, a changing corporate governance structure, and large government deficits. These issues may cause a slowdown of the Japanese economy.
  • Currency Risk. The Japanese yen has fluctuated widely at times and any increase in its value may cause a decline in exports that could weaken the economy.
  • Nuclear Risk. The nuclear power plant catastrophe in Japan in March of 2011 may have short-term and long-term effects on the nuclear energy industry, the extent of which are currently unknown.
  • Labor Risk. Japan has an aging workforce. It is a labor market that is undergoing fundamental structural changes, as traditional lifetime employment clashes with the need for increased labor mobility, which may adversely affect Japan’s economic competitiveness.
  • Geographic Risk. Natural disasters, such as earthquakes, could occur in Japan or surrounding areas and could negatively affect the Japanese economy, and, in turn, could negatively affect the Fund.

Risk of Investing in the United Kingdom. Investment in British issuers may subject the Fund to regulatory, political, currency, security, and economic risk specific to the United Kingdom. The British economy relies heavily on export of financial services to the United States and other European countries. A prolonged slowdown in the financial services sector will have a negative impact on the British economy. In the past, the United Kingdom has been a target of terrorism. Acts of terrorism in the United Kingdom or against British interests abroad may cause uncertainty in the British financial markets and adversely affect the performance of the issuers to which the Fund has exposure. The British economy, along with the United States and certain other European economies, experienced a significant economic slowdown during the recent financial crisis.

Securities Lending Risk. The Fund may engage in securities lending. Securities lending involves the risk that the Fund may lose money because the borrower of the Fund’s loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for the loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Security Risk. Some geographic areas in which the Fund invests have experienced acts of terrorism or strained international relations due to territorial disputes, historical animosities or other defense concerns. These situations may cause uncertainty in the markets of these geographic areas and may adversely affect the performance of their economies.

Tracking Error Risk. Imperfect correlation between the Fund’s portfolio securities and those in the Underlying Index, rounding of prices, changes to the Underlying Index and regulatory requirements may cause tracking error, which is the divergence of the Fund’s performance from that of the Underlying Index. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Underlying Index does not. Because the Fund employs a representative sampling strategy, the Fund may experience tracking error to a greater extent than a fund that seeks to replicate an index.

Valuation Risk. Because non-U.S. exchanges may be open on days when the Fund does not price its shares, the value of the securities in the Fund’s portfolio may change on days when shareholders will not be able to purchase or sell the Fund’s shares. In addition, for purposes of calculating the Fund’s NAV, the value of assets denominated in non-U.S. currencies is converted into U.S. dollars using exchange rates deemed appropriate by BFA. This conversion may result in a difference between the prices used to calculate the Fund’s NAV and the prices used by the Underlying Index, which, in turn, could result in a difference between the Fund’s performance and the performance of the Underlying Index.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

Australasian Economic Risk. The economies of Australasia, which include Australia and New Zealand, are dependent on exports from the agricultural and mining sectors. This makes Australasian economies susceptible to fluctuations in the commodity markets. Australasian economies are also increasingly dependent on their growing service industries. Because the economies of Australasia are dependent on the economies of Asia, Europe and the United States as key trading partners and investors, reduction in spending by any of these trading partners on Australasian products and services, or negative changes in any of these economies, may cause an adverse impact on some or all of the Australasian economies.

Consumer Discretionary Sector Risk. The success of consumer product manufacturers and retailers is tied closely to the performance of domestic and international economies, interest rates, exchange rates, competition, consumer confidence, changes in demographics and consumer preferences. Companies in the consumer discretionary sector depend heavily on disposable household income and consumer spending, and may be strongly affected by social trends and marketing campaigns. These companies may be subject to severe competition, which may have an adverse impact on their profitability.

Energy Sector Risk. The energy sector is cyclical and highly dependent on commodities prices. The market values of companies in the energy sector are strongly affected by the levels and volatility of global energy prices, energy supply and demand, capital expenditures on exploration and production, energy conservation efforts, exchange rates and technological advances, among other factors. Companies in this sector may be subject to substantial government regulation and contractual fixed pricing, which may increase the cost of business and limit these companies’ earnings. A significant portion of their revenues depends on a relatively small number of customers, including governmental entities and utilities. As a result, governmental budget constraints may have a material adverse effect on the stock prices of companies in this industry. Energy companies may also operate in countries with less developed regulatory regimes or a history of expropriation, nationalization or other adverse policies. Energy companies also face a significant risk of civil liability from accidents resulting in injury or loss of life or property, pollution or other environmental mishaps, equipment malfunctions or mishandling of materials and a risk of loss from

terrorism and natural disasters. Any such event could have serious consequences for the general population of the area affected and result in a material adverse impact on the Fund’s portfolio and the performance of the Fund. Energy companies can be significantly affected by the supply of, and demand for, specific products (e.g., oil and natural gas) and services, exploration and production spending, government regulation, world events and general economic conditions.

Health Care Sector Risk. The profitability of companies in the health care sector may be affected by extensive government regulations, restrictions on government reimbursement for medical expenses, rising costs of medical products and services, pricing pressure, an increased emphasis on outpatient services, limited number of products, industry innovation, changes in technologies and other market developments. Many health care companies are heavily dependent on patent protection. The expiration of patents may adversely affect the profitability of these companies. Many health care companies are subject to extensive litigation based on product liability and similar claims. Health care companies are subject to competitive forces that may make it difficult to raise prices and, in fact, may result in price discounting. Many new products in the health care sector may be subject to regulatory approvals. The process of obtaining such approvals may be long and costly. Companies in the health care sector may be thinly capitalized and may be susceptible to product obsolescence.

Materials Sector Risk. Companies in the materials sector could be adversely affected by commodity price volatility, exchange rates, import controls, increased competition, depletion of resources, technical progress, labor relations, exchange rates and government regulations, among other factors. Also, companies in the materials sector are at risk of liability for environmental damage and product liability claims. Production of materials may exceed demand as a result of market imbalances or economic downturns, leading to poor investment returns.

Telecommunications Sector Risk. The telecommunications sector is subject to extensive government regulation. The costs of complying with governmental regulations, delays or failure to receive required regulatory approvals, or the enactment of new adverse regulatory requirements may negatively affect the business of the telecommunications companies. Government actions around the world, specifically in the area of pre-marketing clearance of products and prices, can be arbitrary and unpredictable. Companies in the telecommunications sector may encounter distressed cash flows due to the need to commit substantial capital to meet increasing competition, particularly in formulating new products and services using new technology. Technological innovations may make the products and services of telecommunications companies obsolete.

Portfolio Holdings Information

A description of the Trust’s policies and procedures with respect to the disclosure of the Fund’s portfolio securities is available in the Fund’s Statement of Additional Information (“SAI”). The top holdings of the Fund can be found at www.iShares.com. Fund fact sheets provide information regarding the Fund’s top holdings and may be requested by calling 1-800-iShares (1-800-474-2737).

Management

Investment Adviser. As investment adviser, BFA has overall responsibility for the general management and administration of the Trust. BFA provides an investment program for the Fund and manages the investment of the Fund’s assets. In managing the Fund, BFA may draw upon the research and expertise of its asset management affiliates with respect to certain portfolio securities. In seeking to achieve the Fund’s investment objective, BFA uses teams of portfolio managers, investment strategists and other investment specialists. This team approach brings together many disciplines and leverages BFA’s extensive resources.

Pursuant to the Investment Advisory Agreement between BFA and the Trust (entered into on behalf of the Fund), BFA is responsible for substantially all expenses of the Fund, except interest expenses, taxes, brokerage expenses, future distribution fees or expenses and extraordinary expenses.

For its investment advisory services to the Fund, BFA is entitled to receive a management fee from the Fund corresponding to the Fund’s allocable portion of an aggregate management fee based on the aggregate average daily net assets of the following iShares funds: iShares MSCI ACWI ex US Index Fund, iShares MSCI ACWI Index Fund, iShares MSCI All Country World Minimum Volatility Index Fund, iShares MSCI EAFE Index Fund and iShares MSCI EAFE Minimum Volatility Index Fund. The aggregate management fee is calculated as follows: 0.35% per annum of the aggregate net assets less than or equal to $30.0 billion, plus 0.32% per annum of the aggregate net assets over $30.0 billion up to and including $60.0 billion, plus 0.28% per annum of the aggregate net assets in excess of $60.0 billion. As calculated on July 31, 2011, for its investment advisory services to the Fund, BFA is entitled to receive a management fee from the Fund, based on a percentage of the Fund’s average daily net assets, at an annual rate of 0.34%.

BFA is located at 400 Howard Street, San Francisco, CA 94105. It is a wholly owned subsidiary of BTC, which in turn is indirectly wholly-owned by BlackRock, Inc. (“BlackRock”). As of September 30, 2011, BTC and its affiliates, including BFA and BlackRock, provided investment advisory services for assets in excess of $3.35 trillion. BFA, BTC, BlackRock Execution Services, BlackRock and their affiliates deal, trade and invest for their own accounts in the types of securities in which the Fund may also invest.

A discussion regarding the basis for the Trust’s Board of Trustees’ (the “Board”) approval of the Investment Advisory Agreement with BFA is available in the Fund’s annual report for the period ended July 31.

Portfolio Managers. Rene Casis, Diane Hsiung and Greg Savage are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager is responsible for various functions related to portfolio management, including, but not limited to, investing cash inflows, coordinating with members of his or her portfolio management team to focus on certain asset classes, implementing investment strategy, researching and reviewing investment strategy and overseeing members of his or her portfolio management team that have more limited responsibilities.

Rene Casis has been employed by BFA (formerly, Barclays Global Fund Advisors (“BGFA”)) and BTC (formerly, Barclays Global Investors, N.A. (“BGI”)) as a senior portfolio manager since 2009. From 2005 to 2009, Mr. Casis was a trader at Barclays Capital. Prior to that, Mr. Casis was a portfolio manager from 2000 to 2005 for BGFA and BGI. Mr. Casis has been a Portfolio Manager of the Fund since 2010.

Diane Hsiung has been employed by BFA and BTC as a senior portfolio manager since 2007. Prior to that, Ms. Hsiung was a portfolio manager from 2002 to 2006 for BGFA and BGI. Ms. Hsiung has been a Portfolio Manager of the Fund since 2008.

Greg Savage has been employed by BFA and BTC as a senior portfolio manager since 2006. Prior to that, Mr. Savage was a portfolio manager from 2001 to 2006 for BGFA and BGI. Mr. Savage has been a Portfolio Manager of the Fund since 2008.

The Fund’s SAI provides additional information about the Portfolio Managers’ compensation, other accounts managed by the Portfolio Managers and the Portfolio Managers’ ownership (if any) of shares in the Fund.

Administrator, Custodian and Transfer Agent. State Street Bank and Trust Company (“State Street”) is the administrator, custodian and transfer agent for the Fund.

Conflicts of Interest. BFA wants you to know that there are certain entities with which BFA has relationships that may give rise to conflicts of interest, or the appearance of conflicts of interest. These entities include the following: BFA’s affiliates (including BlackRock and The PNC Financial Services Group, Inc., and each of their affiliates, directors, partners, trustees, managing members, officers and employees (collectively, the “Affiliates”)) and BlackRock’s significant shareholder, Barclays Bank PLC and its affiliates, including Barclays PLC (each, an “Entity” and together, the “Entities”).

The activities of BFA, the Affiliates and the Entities in the management of, or their interest in, their own accounts and other accounts they manage, may present conflicts of interest that could disadvantage the Fund and its shareholders. BFA and its Affiliates or the Entities provide investment management services to other funds and discretionary managed accounts that may follow an investment program similar to that of the Fund. BFA, its Affiliates and the Entities are involved worldwide with a broad spectrum of financial services and asset management activities and may engage in the ordinary course of business in activities in which their interests or the interests of their clients may conflict with those of the Fund. BFA, one or more of the Affiliates or the Entities acts, or may act, as an investor, investment banker, research provider, investment manager, financier, underwriter, advisor, market maker, trader, prime broker, lender, agent or principal, and have other direct and indirect interests, in securities, currencies and other instruments in which the Fund may directly or indirectly invest. Thus, it is likely that the Fund will have multiple business relationships with and will invest in, engage in transactions with, make voting decisions with respect to, or obtain services from, entities for which BFA, an Affiliate or an Entity performs or seeks to perform investment banking or other services.

BFA or one or more Affiliates or Entities may engage in proprietary trading and advise accounts and funds that have investment objectives similar to those of the Fund and/

or that engage in and compete for transactions in the same types of securities, currencies and other instruments as the Fund, including in securities issued by other open-end and closed-end investment management companies, including investment companies that are affiliated with the Fund and BFA, to the extent permitted under the Investment Company Act of 1940, as amended (the “1940 Act”). The trading activities of BFA, these Affiliates and Entities are carried out without reference to positions held directly or indirectly by the Fund and may result in BFA, an Affiliate or an Entity having positions that are adverse to those of the Fund.

No Affiliate or Entity is under any obligation to share any investment opportunity, idea or strategy with the Fund. As a result, an Affiliate or an Entity may compete with the Fund for appropriate investment opportunities. As a result of this and several other factors, the results of the Fund’s investment activities may differ from those of an Affiliate or an Entity and of other accounts managed by an Affiliate or an Entity, and it is possible that the Fund could sustain losses during periods in which one or more Affiliates or Entities and other accounts achieve profits on their trading for proprietary or other accounts. The opposite result is also possible.

The Fund may, from time to time, enter into transactions in which BFA or an Affiliate’s or an Entity’s clients have an interest adverse to the Fund. Furthermore, transactions undertaken by Affiliate-advised clients may adversely impact the Fund. Transactions by one or more Affiliate- or Entity-advised clients or BFA may have the effect of diluting or otherwise disadvantaging the values, prices or investment strategies of the Fund.

An Entity may maintain securities indices as part of its product offerings. Index-based funds seek to track the performance of securities indices and may use the name of the index in the fund name. Index providers, including the Entities, may be paid licensing fees for use of their indices or index names. Entities will not be obligated to license their indices to BFA and its Affiliates, and BFA and its Affiliates will not be assured that the terms of any index licensing agreement with the Entities will be as favorable as those terms offered to other index licensees.

The Fund’s activities may be limited because of regulatory restrictions applicable to one or more Affiliates or Entities, and/or their internal policies designed to comply with such restrictions. In addition, the Fund may invest in securities of companies with which an Affiliate or an Entity has or is trying to develop investment banking relationships or in which an Affiliate or an Entity has significant debt or equity investments. The Fund also may invest in securities of companies for which an Affiliate or an Entity provides or may some day provide research coverage. An Affiliate or an Entity may have business relationships with and purchase or distribute or sell services or products from or to distributors, consultants or others who recommend the Fund or who engage in transactions with or for the Fund, and may receive compensation for such services. The Fund may also make brokerage and other payments to Affiliates or Entities in connection with the Fund’s portfolio investment transactions.

Pursuant to a securities lending program approved by the Board, the Fund has retained an Affiliate of BFA to serve as the securities lending agent for the Fund to the extent that the Fund participates in the securities lending program. For these services, the lending agent may receive a fee from the Fund, including a fee based on the returns earned on the Fund’s investment of the cash received as collateral for any loaned

securities. In addition, one or more Affiliates may be among the entities to which the Fund may lend its portfolio securities under the securities lending program.

The activities of BFA, the Affiliates or Entities may give rise to other conflicts of interest that could disadvantage the Fund and its shareholders. BFA has adopted policies and procedures designed to address these potential conflicts of interest. See the Fund’s SAI for further information.

Shareholder Information

Additional shareholder information, including how to buy and sell shares of the Fund, is available free of charge by calling toll-free: 1-800-iShares (1-800-474-2737) or visiting our website at www.iShares.com.

Buying and Selling Shares. Shares of the Fund may be acquired or redeemed directly from the Fund only in Creation Units or multiples thereof, as discussed in the Creations and Redemptions section of this Prospectus. Only an Authorized Participant (as defined in the Creations and Redemptions section) may engage in creation or redemption transactions directly with the Fund. Once created, shares of the Fund generally trade in the secondary market in amounts less than a Creation Unit.

Shares of the Fund are listed on a national securities exchange for trading during the trading day. Shares can be bought and sold throughout the trading day like shares of other publicly-traded companies. The Trust does not impose any minimum investment for shares of the Fund purchased on an exchange. The Fund’s shares trade under the trading symbol “EFA.”

Buying or selling Fund shares on an exchange involves two types of costs that may apply to all securities transactions. When buying or selling shares of the Fund through a broker, you will likely incur a brokerage commission or other charges determined by your broker. The commission is frequently a fixed amount and may be a significant proportional cost for investors seeking to buy or sell small amounts of shares. In addition, you may incur the cost of the “spread” – that is, any difference between the bid price and the ask price. The spread varies over time for shares of the Fund based on its trading volume and market liquidity, and is generally lower if the Fund has a lot of trading volume and market liquidity, and higher if the Fund has little trading volume and market liquidity.

The Board has adopted a policy of not monitoring for frequent purchases and redemptions of Fund shares (“frequent trading”) that appear to attempt to take advantage of a potential arbitrage opportunity presented by a lag between a change in the value of the Fund’s portfolio securities after the close of the primary markets for the Fund’s portfolio securities and the reflection of that change in the Fund’s NAV (“market timing”), because the Fund generally sells and redeems its shares directly through transactions that are in-kind and/or for cash, subject to the conditions described below under Creations and Redemptions. The Board has not adopted a policy of monitoring for other frequent trading activity because shares of the Fund are listed for trading on a national securities exchange.

The national securities exchange on which the Fund’s shares are listed is open for trading Monday through Friday and is closed on weekends and the following holidays:

New Year’s Day, Martin Luther King, Jr. Day, Presidents’ Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day. The Fund’s primary listing exchange is NYSE Arca.

Section 12(d)(1) of the 1940 Act restricts investments by investment companies in the securities of other investment companies. Registered investment companies are permitted to invest in the Fund beyond the limits set forth in Section 12(d)(1), subject to certain terms and conditions set forth in SEC rules or in an SEC exemptive order issued to the Trust. In order for a registered investment company to invest in shares of the Fund beyond the limitations of Section 12(d)(1) pursuant to the exemptive relief obtained by the Trust, the registered investment company must enter into an agreement with the Trust.

Book Entry. Shares of the Fund are held in book-entry form, which means that no stock certificates are issued. The Depository Trust Company (“DTC”) or its nominee is the record owner of all outstanding shares of the Fund and is recognized as the owner of all shares for all purposes.

Investors owning shares of the Fund are beneficial owners as shown on the records of DTC or its participants. DTC serves as the securities depository for shares of the Fund. DTC participants include securities brokers and dealers, banks, trust companies, clearing corporations and other institutions that directly or indirectly maintain a custodial relationship with DTC. As a beneficial owner of shares, you are not entitled to receive physical delivery of stock certificates or to have shares registered in your name, and you are not considered a registered owner of shares. Therefore, to exercise any right as an owner of shares, you must rely upon the procedures of DTC and its participants. These procedures are the same as those that apply to any other securities that you hold in book-entry or “street name” form.

Share Prices. The trading prices of the Fund’s shares in the secondary market generally differ from the Fund’s daily NAV and are affected by market forces such as supply and demand, economic conditions and other factors. Information regarding the intraday value of shares of the Fund, also known as the “indicative optimized portfolio value” (“IOPV”), is disseminated every 15 seconds throughout the trading day by the national securities exchange on which the Fund’s shares are listed or by market data vendors or other information providers. The IOPV is based on the current market value of the securities and/or cash required to be deposited in exchange for a Creation Unit. The IOPV does not necessarily reflect the precise composition of the current portfolio of securities held by the Fund at a particular point in time or the best possible valuation of the current portfolio. Therefore, the IOPV should not be viewed as a “real-time” update of the Fund’s NAV, which is computed only once a day. The IOPV is generally determined by using both current market quotations and/or price quotations obtained from broker-dealers that may trade in the portfolio securities held by the Fund. The quotations of certain Fund holdings may not be updated during U.S. trading hours if such holdings do not trade in the United States. The Fund is not involved in, or responsible for, the calculation or dissemination of the IOPV and makes no representation or warranty as to its accuracy.

Determination of Net Asset Value. The NAV of the Fund normally is determined once daily Monday through Friday, generally as of the regularly scheduled close of

business of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m., Eastern time) on each day that the NYSE is open for trading, based on prices at the time of closing provided that (a) any Fund assets or liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers (as detailed below) and (b) U.S. fixed income assets may be valued as of the announced closing time for trading in fixed income instruments in a particular market or exchange. The NAV of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets held by the Fund, and its liabilities, are determined pursuant to valuation policies and procedures approved by the Board. The Fund’s assets and liabilities are valued primarily on the basis of market quotations.

Equity investments are valued at market value, which is generally determined using the last reported official closing price or last trading price on the exchange or market on which the security is primarily traded at the time of valuation.

The Fund invests in foreign securities. Foreign currency exchange rates are generally determined as of 4:00 p.m., London time. Foreign securities owned by the Fund may trade on weekends or other days when the Fund does not price its shares. As a result, the Fund’s NAV may change on days when Authorized Participants will not be able to purchase or redeem Fund shares.

Generally, trading in foreign securities, U.S. government securities, money market instruments and certain fixed-income securities is substantially completed each day at various times prior to the close of business on the NYSE. The values of such securities used in computing the NAV of the Fund are determined as of such times.

When market quotations are not readily available or are believed by BFA to be unreliable, the Fund’s investments are valued at fair value. Fair value determinations are made by BFA in accordance with policies and procedures approved by the Fund’s Board. BFA may conclude that a market quotation is not readily available or is unreliable if a security or other asset or liability does not have a price source due to its lack of liquidity, if a market quotation differs significantly from recent price quotations or otherwise no longer appears to reflect fair value, where the security or other asset or liability is thinly traded, or where there is a significant event subsequent to the most recent market quotation. A “significant event” is an event that, in the judgment of BFA, is likely to cause a material change to the closing market price of the asset or liability held by the Fund. Foreign securities whose values are affected by volatility that occurs in U.S. markets on a trading day after the close of foreign securities markets may be fair valued.

Fair value represents a good faith approximation of the value of an asset or liability. The fair value of an asset or liability held by the Fund is the amount the Fund might reasonably expect to receive from the current sale of that asset or the cost to extinguish that liability in an arm’s-length transaction. Valuing the Fund’s investments using fair value pricing will result in prices that may differ from current market valuations and that may not be the price at which those investments could have been

sold during the period in which the particular fair values were used. Use of fair value prices and certain current market valuations could result in a difference between the prices used to calculate the Fund’s NAV and the prices used by the Underlying Index, which, in turn, could result in a difference between the Fund’s performance and the performance of the Underlying Index.

The value of assets or liabilities denominated in non-U.S. currencies will be converted into U.S. dollars using exchange rates deemed appropriate by BFA as investment adviser. Use of a rate different from the rate used by the Index Provider may adversely affect the Fund’s ability to track the Underlying Index.

Dividends and Distributions

General Policies. Dividends from net investment income, if any, generally are declared and paid semi-annually by the Fund. Distributions of net realized securities gains, if any, generally are declared and paid once a year, but the Trust may make distributions on a more frequent basis for the Fund. The Trust reserves the right to declare special distributions if, in its reasonable discretion, such action is necessary or advisable to preserve its status as a regulated investment company (“RIC”) or to avoid imposition of income or excise taxes on undistributed income or realized gains.

Dividends and other distributions on shares of the Fund are distributed on a pro rata basis to beneficial owners of such shares. Dividend payments are made through DTC participants and indirect participants to beneficial owners then of record with proceeds received from the Fund.

Dividend Reinvestment Service. No dividend reinvestment service is provided by the Trust. Broker-dealers may make available the DTC book-entry Dividend Reinvestment Service for use by beneficial owners of the Fund for reinvestment of their dividend distributions. Beneficial owners should contact their broker to determine the availability and costs of the service and the details of participation therein. Brokers may require beneficial owners to adhere to specific procedures and timetables. If this service is available and used, dividend distributions of both income and realized gains will be automatically reinvested in additional whole shares of the Fund purchased in the secondary market.

Taxes. As with any investment, you should consider how your investment in shares of the Fund will be taxed. The tax information in this Prospectus is provided as general information, based on current law. You should consult your own tax professional about the tax consequences of an investment in shares of the Fund.

Unless your investment in Fund shares is made through a tax-exempt entity or tax-deferred retirement account, such as an IRA, you need to be aware of the possible tax consequences when the Fund makes distributions or you sell Fund shares.

Taxes on Distributions. Distributions from the Fund’s net investment income (other than qualified dividend income), including distributions of income from securities lending and distributions out of the Fund’s net short-term capital gains, if any, are taxable to you as ordinary income. Distributions by the Fund of net long-term capital gains in excess of net short-term capital losses (capital gain dividends) are taxable to you as long-term capital gains, generally at a 15% tax rate (0% at certain income levels), regardless of how long you have held the Fund’s shares. Distributions by the

Fund that qualify as qualified dividend income are taxable to you at long-term capital gain rates for taxable years beginning on or before December 31, 2012. The 15% and 0% tax rates expire for taxable years beginning after December 31, 2012. Maximum long-term capital gain income tax rates are scheduled to rise to 20% in 2013. Beginning in 2013, a 3.8% U.S. federal Medicare contribution tax will be imposed on “net investment income,” including interest, dividends, and capital gains, of U.S. individuals with income exceeding $200,000 (or $250,000 if married and filing jointly), and of estates and trusts.

Dividends will be qualified dividend income to you if they are attributable to qualified dividend income received by the Fund. Generally, qualified dividend income includes dividend income from taxable U.S. corporations and qualified non-U.S. corporations, provided that the Fund satisfies certain holding period requirements in respect of the stock of such corporations and has not hedged its position in the stock in certain ways. Substitute dividends received by the Fund with respect to dividends paid on securities lent out will not be qualified dividend income. For this purpose, a qualified non-U.S. corporation means any non-U.S. corporation that is eligible for benefits under a comprehensive income tax treaty with the United States, which includes an exchange of information program or if the stock with respect to which the dividend was paid is readily tradable on an established United States securities market. The term excludes a corporation that is a passive foreign investment company.

Dividends received by the Fund from a real estate investment trust (“REIT”) or another RIC generally are qualified dividend income only to the extent the dividend distributions are made out of qualified dividend income received by such REIT or RIC. It is expected that dividends received by the Fund from a REIT and distributed to a shareholder generally will be taxable to the shareholder as ordinary income.

For a dividend to be treated as qualified dividend income, the dividend must be received with respect to a share of stock held without being hedged by the Fund, and with respect to a share of the Fund held without being hedged by you, for 61 days during the 121-day period beginning at the date which is 60 days before the date on which such share becomes ex-dividend with respect to such dividend or, in the case of certain preferred stock, 91 days during the 181-day period beginning 90 days before such date.

If your Fund shares are loaned out pursuant to a securities lending arrangement, you may lose the ability to use foreign tax credits passed through by the Fund or to treat Fund dividends paid while the shares are held by the borrower as qualified dividend income.

In general, your distributions are subject to U.S. federal income tax for the year when they are paid. Certain distributions paid in January, however, may be treated as paid on December 31 of the prior year.

If the Fund’s distributions exceed current and accumulated earnings and profits, all or a portion of the distributions made in the taxable year may be recharacterized as a return of capital to shareholders. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and result in a higher capital gain or lower capital loss when those shares on which the distribution was received are

sold. Once a shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain, if the shareholder holds shares of the Fund as capital assets.

If you are neither a resident nor a citizen of the United States or if you are a non-U.S. entity, the Fund’s ordinary income dividends (which include distributions of net short-term capital gains) will generally be subject to a 30% U.S. withholding tax, unless a lower treaty rate applies, provided that withholding tax will generally not apply to any gain or income realized by a non-U.S. shareholder in respect of any distributions of long-term capital gains or upon the sale or other disposition of shares of the Fund.

A 30% withholding tax will be imposed on dividends paid after December 31, 2013, and redemption proceeds paid after December 31, 2014, to (i) foreign financial institutions including non-U.S. investment funds unless they agree to collect and disclose to the Internal Revenue Service (“IRS”) information regarding their direct and indirect U.S. account holders and (ii) certain other foreign entities, unless they certify certain information regarding their direct and indirect U.S. owners. To avoid withholding, foreign financial institutions will need to enter into agreements with the IRS that state that they will provide the IRS information, including the name, address and taxpayer identification number of direct and indirect U.S. account holders, comply with due diligence procedures with respect to the identification of U.S. accounts, report to the IRS certain information with respect to U.S. accounts maintained, agree to withhold tax on certain payments made to non-compliant foreign financial institutions or to account holders who fail to provide the required information, and determine certain other information as to their account holders. Other foreign entities will need to provide the name, address, and taxpayer identification number of each substantial U.S. owner or certifications of no substantial U.S. ownership unless certain exceptions apply.

Dividends, interest and capital gains earned by the Fund with respect to non-U.S. securities may give rise to withholding and other taxes imposed by non-U.S. countries. Tax conventions between certain countries and the United States may reduce or eliminate such taxes. If more than 50% of the total assets of the Fund at the close of a year consists of non-U.S. stocks or securities, the Fund may “pass through” to you certain non-U.S. income taxes (including withholding taxes) paid by the Fund. This means that you would be considered to have received as an additional dividend your share of such non-U.S. taxes, but you may be entitled to either a corresponding tax deduction in calculating your taxable income, or, subject to certain limitations, a credit in calculating your U.S. federal income tax.

For purposes of foreign tax credits for U.S. shareholders of the Fund, foreign capital gains taxes may not produce associated foreign source income, thereby limiting a U.S. person’s ability to use such credits.

If you are a resident or a citizen of the United States, by law, back-up withholding will apply to your distributions and proceeds if you have not provided a taxpayer identification number or social security number and made other required certifications.

Taxes When Shares are Sold. Currently, any capital gain or loss realized upon a sale of Fund shares is generally treated as a long-term gain or loss if the shares have been held for more than one year. Any capital gain or loss realized upon a sale of Fund

shares held for one year or less is generally treated as short-term gain or loss, except that any capital loss on the sale of shares held for six months or less is treated as long-term capital loss to the extent that capital gain dividends were paid with respect to such shares. Beginning in 2013, any such capital gains, including from sales of Fund shares or from capital gain dividends, will be included in “net investment income” for purposes of the 3.8% U.S. federal Medicare contribution tax mentioned above.

The foregoing discussion summarizes some of the consequences under current U.S. federal tax law of an investment in the Fund. It is not a substitute for personal tax advice. You may also be subject to state and local taxation on Fund distributions and sales of shares. Consult your personal tax adviser about the potential tax consequences of an investment in shares of the Fund under all applicable tax laws.

Creations and Redemptions. Prior to trading in the secondary market, shares of the Fund are “created” at NAV by market makers, large investors and institutions only in block-size Creation Units of 600,000 shares or multiples thereof. Each “creator” or “Authorized Participant” enters into an authorized participant agreement with the Fund’s distributor, SEI Investments Distribution Co. (the “Distributor”). Only an Authorized Participant may create or redeem Creation Units directly with the Fund. A creation transaction, which is subject to acceptance by the transfer agent, generally takes place when an Authorized Participant deposits into the Fund a designated portfolio of securities and a specified amount of cash approximating the holdings of the Fund in exchange for a specified number of Creation Units. To the extent practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund.

Similarly, shares can be redeemed only in Creation Units, generally for a designated portfolio of securities and a specified amount of cash held by the Fund (“Fund Securities”). Except when aggregated in Creation Units, shares are not redeemable by the Fund. The prices at which creations and redemptions occur are based on the next calculation of NAV after an order is received in a form described in the authorized participant agreement.

The Fund intends to comply with the U.S. federal securities laws in accepting securities for deposit and satisfying redemptions with redemption securities by, among other means, assuring that any securities accepted for deposit and any securities used to satisfy redemption requests will be sold in transactions that would be exempt from registration under the Securities Act of 1933, as amended (the “1933 Act”). Further, an Authorized Participant that is not a “qualified institutional buyer,” as such term is defined under Rule 144A of the 1933 Act, will not be able to receive Fund Securities that are restricted securities eligible for resale under Rule 144A.

Creations and redemptions must be made through a firm that is either a member of the Continuous Net Settlement System of the National Securities Clearing Corporation or a DTC participant and has executed an agreement with the Distributor with respect to creations and redemptions of Creation Unit aggregations. Information about the procedures regarding creation and redemption of Creation Units (including the cut-off times for receipt of creation and redemption orders) is included in the Fund’s SAI.

Because new shares may be created and issued on an ongoing basis, at any point during the life of the Fund a “distribution,” as such term is used in the 1933 Act, may be occurring. Broker-dealers and other persons are cautioned that some activities on their part may, depending on the circumstances, result in their being deemed participants in a distribution in a manner that could render them statutory underwriters and subject to the prospectus delivery and liability provisions of the 1933 Act. Any determination of whether one is an underwriter must take into account all the relevant facts and circumstances of each particular case.

Broker-dealers should also note that dealers who are not “underwriters” but are participating in a distribution (as contrasted to ordinary secondary transactions), and thus dealing with shares that are part of an “unsold allotment” within the meaning of Section 4(3)(C) of the 1933 Act, would be unable to take advantage of the prospectus delivery exemption provided by Section 4(3) of the 1933 Act. For delivery of prospectuses to exchange members, the prospectus delivery mechanism of Rule 153 under the 1933 Act is available only with respect to transactions on a national securities exchange.

Costs Associated with Creations and Redemptions. Authorized Participants are charged standard creation and redemption transaction fees to offset transfer and other transaction costs associated with the issuance and redemption of Creation Units. The standard creation and redemption transaction fees are set forth in the table below. The standard creation transaction fee is charged to the Authorized Participant on the day such Authorized Participant creates a Creation Unit, and is the same regardless of the number of Creation Units purchased by the Authorized Participant on the applicable business day. Similarly, the standard redemption transaction fee is charged to the Authorized Participant on the day such Authorized Participant redeems a Creation Unit, and is the same regardless of the number of Creation Units redeemed by the Authorized Participant on the applicable business day. Creations and redemptions for cash (when cash creations and redemptions (in whole or in part) are available or specified) are also subject to an additional charge (up to the maximum amounts shown in the table below). This charge is intended to compensate for brokerage, tax, foreign exchange, execution, market impact and other costs and expenses related to cash transactions. Investors who use the services of a broker or other financial intermediary may pay fees for such services.

The following table shows, as of September 30, 2011, the approximate value of one Creation Unit, standard fees and maximum additional charges for creations and redemptions (as described above):

* As a percentage of the net asset value per Creation Unit, inclusive, in the case of redemptions, of the standard redemption transaction fee.

Householding. Householding is an option available to certain Fund investors. Householding is a method of delivery, based on the preference of the individual investor, in which a single copy of certain shareholder documents can be delivered to investors who share the same address, even if their accounts are registered under different names. Please contact your broker-dealer if you are interested in enrolling in householding and receiving a single copy of prospectuses and other shareholder documents, or if you are currently enrolled in householding and wish to change your householding status.

Distribution

The Distributor distributes Creation Units for the Fund on an agency basis. The Distributor does not maintain a secondary market in shares of the Fund. The Distributor has no role in determining the policies of the Fund or the securities that are purchased or sold by the Fund. The Distributor’s principal address is One Freedom Valley Drive, Oaks, PA 19456.

In addition, BFA or its Affiliates make payments to broker-dealers, banks or other financial intermediaries (together, “intermediaries”) related to marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems, or their making shares of the Fund and certain other iShares funds available to their customers. Such payments, which may be significant to the intermediary, are not made by the Fund. Rather, such payments are made by BFA or its Affiliates from their own resources, which come directly or indirectly in part from fees paid by the iShares funds complex. Payments of this type are sometimes referred to as revenue-sharing payments. A financial intermediary may make decisions about which investment options it recommends or makes available, or the level of services provided, to its customers based on the revenue-sharing payments it is eligible to receive. Therefore, such payments to an intermediary create conflicts of interest between the intermediary and its customers and may cause the intermediary to recommend the Fund or other iShares funds over another investment. More information regarding these payments is contained in the Fund’s SAI. Please contact your salesperson or other investment professional for more information regarding any such payments his or her firm may receive from BFA or its Affiliates.

Financial Highlights

The financial highlights table is intended to help investors understand the Fund’s financial performance for the past five years. Certain information reflects financial results for a single share of the Fund. The total returns in the table represent the rate that an investor would have earned (or lost) on an investment in the Fund, assuming reinvestment of all dividends and distributions. This information has been audited by PricewaterhouseCoopers LLP, whose report is included, along with the Fund’s financial statements, in the Fund’s Annual Report (available upon request).

Supplemental Information

I. Premium/Discount Information

The table that follows presents information about the differences between the daily market price on secondary markets for shares of the Fund and the Fund’s NAV. NAV is the price at which the Fund issues and redeems shares. It is calculated in accordance with the standard formula for valuing mutual fund shares. The price used to calculate market returns (“Market Price”) of the Fund generally is determined using the midpoint between the highest bid and the lowest offer on the primary securities exchange on which shares of the Fund are listed for trading, as of the time that the Fund’s NAV is calculated. The Fund’s Market Price may be at, above or below its NAV. The NAV of the Fund will fluctuate with changes in the value of its portfolio holdings. The Market Price of the Fund will fluctuate in accordance with changes in its NAV, as well as market supply and demand.

Premiums or discounts are the differences (expressed as a percentage) between the NAV and Market Price of the Fund on a given day, generally at the time the NAV is calculated. A premium is the amount that the Fund is trading above the reported NAV, expressed as a percentage of the NAV. A discount is the amount that the Fund is trading below the reported NAV, expressed as a percentage of the NAV.

The following information shows the frequency of distributions of premiums and discounts for the Fund for each full calendar quarter of 2010 through September 30, 2011.

Each line in the table shows the number of trading days in which the Fund traded within the premium/discount range indicated. The number of trading days in each premium/discount range is also shown as a percentage of the total number of trading days in the period covered by the table. All data presented here represents past performance, which cannot be used to predict future results.

II. Total Return Information

The tables that follow present information about the total returns of the Fund and the Underlying Index as of the fiscal year ended July 31, 2011.

“Average Annual Total Returns” represent the average annual change in value of an investment over the periods indicated. “Cumulative Total Returns” represent the total change in value of an investment over the periods indicated.

The Fund’s NAV is the value of one share of the Fund as calculated in accordance with the standard formula for valuing mutual fund shares. The NAV return is based on the NAV of the Fund and the market return is based on the Market Price of the Fund. Market Price is determined by using the midpoint between the highest bid and the lowest offer on the primary stock exchange on which shares of the Fund are listed for trading, as of the time that the Fund’s NAV is calculated. Since shares of the Fund did not trade in the secondary market until after the Fund’s inception, for the period from inception to the first day of secondary market trading in shares of the Fund, the NAV of the Fund is used as a proxy for the Market Price to calculate market returns. Market and NAV returns assume that dividends and capital gain distributions have been reinvested in the Fund at Market Price and NAV, respectively.

An index is a statistical composite that tracks a specified financial market or sector. Unlike the Fund, the Underlying Index does not actually hold a portfolio of securities and therefore does not incur the expenses incurred by the Fund. These expenses negatively impact the performance of the Fund. Also, market returns do not include brokerage commissions that may be payable on secondary market transactions. If brokerage commissions were included, market returns would be lower. The returns shown in the following tables do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption or sale of Fund shares. The investment return and principal value of shares of the Fund will vary with changes in market conditions. Shares of the Fund may be worth more or less than their original cost when they are redeemed or sold in the market. The Fund’s past performance is no guarantee of future results.

Fund Overview

iSHARES® MSCI EAFE SMALL CAP INDEX FUND

Ticker: SCZ Stock Exchange: NYSE Arca

Investment Objective

The iShares MSCI EAFE Small Cap Index Fund (the “Fund”) seeks investment results that correspond generally to the price and yield performance, before fees and expenses, of the MSCI EAFE Small Cap Index (the “Underlying Index”).

Fees and Expenses

The following table describes the fees and expenses that you will incur if you own shares of the Fund. The investment advisory agreement between iShares Trust (the “Trust”) and BlackRock Fund Advisors (“BFA”) (the “Investment Advisory Agreement”) provides that BFA will pay all operating expenses of the Fund, except interest expenses, taxes, brokerage expenses, future distribution fees or expenses, and extraordinary expenses.

You may also incur usual and customary brokerage commissions when buying or selling shares of the Fund, which are not reflected in the example that follows:

Example. This Example is intended to help you compare the cost of owning shares of the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

Portfolio Turnover. The Fund may pay transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 12% of the average value of its portfolio.

Principal Investment Strategies

The Underlying Index represents the small-cap segment of the MSCI EAFE Index. As of September 30, 2011, the Underlying Index consisted of the following 22 developed market country indexes or regions: Australia, Austria, Belgium, Denmark, Finland, France, Germany, Greece, Hong Kong, Ireland, Israel, Italy, Japan, the Netherlands, New Zealand, Norway, Portugal, Singapore, Spain, Sweden, Switzerland and the United Kingdom. Under MSCI’s Global Investable Market Index methodology, the small-cap universe consists of the securities of those companies whose securities are not included in the large-cap or mid-cap segments of a particular market, which together comprise approximately 85% of each market’s free float-adjusted market capitalization. The small-cap segment covers the 85%-99% range of each market’s free float-adjusted market capitalization. Component companies include consumer discretionary, financial and industrial companies.

BFA uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to “beat” the index it tracks and does not seek temporary defensive positions when markets decline or appear overvalued.

Indexing may eliminate the chance that the Fund will substantially outperform the Underlying Index but also may reduce some of the risks of active management, such as poor security selection. Indexing seeks to achieve lower costs and better after-tax performance by keeping portfolio turnover low in comparison to actively managed investment companies.

BFA uses a representative sampling indexing strategy to manage the Fund. “Representative sampling” is an indexing strategy that involves investing in a representative sample of securities that collectively has an investment profile similar to the Underlying Index. The securities selected are expected to have, in the aggregate, investment characteristics (based on factors such as market capitalization and industry weightings), fundamental characteristics (such as return variability and yield) and liquidity measures similar to those of the Underlying Index. The Fund may or may not hold all of the securities in the Underlying Index.

The Fund generally invests at least 90% of its assets in securities of the Underlying Index and in depositary receipts representing securities of the Underlying Index. The Fund may invest the remainder of its assets in securities not included in the Underlying Index, but which BFA believes will help the Fund track the Underlying Index and in

S-2

other investments including futures contracts, options on futures contracts, options and swaps as well as cash and cash equivalents, including shares of money market funds advised by BFA or its affiliates.

The Fund may lend securities representing up to one-third of the value of the Fund’s total assets (including the value of the collateral received).

The Underlying Index is sponsored by an organization (the “Index Provider”) that is independent of the Fund and BFA. The Index Provider determines the composition and relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index. The Fund’s Index Provider is MSCI Inc. (“MSCI”).

Industry Concentration Policy. The Fund will concentrate its investments (i.e., hold 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. For purposes of this limitation, securities of the U.S. government (including its agencies and instrumentalities) and repurchase agreements collateralized by U.S. government securities are not considered to be issued by members of any industry.

Summary of Principal Risks

As with any investment, you could lose all or part of your investment in the Fund, and the Fund’s performance could trail that of other investments. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund’s net asset value per share (“NAV”), trading price, yield, total return and ability to meet its investment objective.

Asset Class Risk. Securities in the Underlying Index or in the Fund’s portfolio may underperform in comparison to the general securities markets or other asset classes.

Concentration Risk. To the extent that the Fund’s investments are concentrated in a particular issuer, region, country, market, industry or asset class, the Fund may be susceptible to loss due to adverse occurrences affecting that issuer, region, country, market, industry or asset class.

Consumer Discretionary Sector Risk. The consumer discretionary sector may be affected by changes in domestic and international economies, exchange and interest rates, competition, consumers’ disposable income and consumer preferences, social trends and marketing campaigns.

Currency Risk. Because the Fund’s NAV is determined in U.S. dollars, the Fund’s NAV could decline if the currency of a non-U.S. market in which the Fund invests depreciates against the U.S. dollar.

Equity Securities Risk. Equity securities are subject to changes in value and their values may be more volatile than other asset classes.

Financial Sector Risk. Performance of companies in the financial sector may be adversely impacted by many factors, including, among others, government regulations, economic conditions, credit rating downgrades, changes in interest rates, and decreased liquidity in credit markets. This sector has experienced significant losses in the recent past, and the impact of more stringent capital

requirements and of recent or future regulation on any individual financial company or on the sector as a whole cannot be predicted.

Geographic Risk. A natural or other disaster could occur in a geographic region in which the Fund invests, which could affect the economy or particular business operations of companies in the specific geographic region, causing an adverse impact on the Fund’s investments in the affected region.

Industrials Sector Risk. The industrials sector is affected by changes in the supply and demand for products and services, product obsolescence, claims for environmental damage or product liability and general economic conditions, among other factors.

Issuer Risk. Fund performance depends on the performance of individual securities to which the Fund has exposure. Changes to the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA’s investment management strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares, losses from trading in secondary markets, periods of high volatility and disruption in the creation/redemption process of the Fund. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV.

Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers are subject to the risks associated with investing in those non-U.S. markets, such as heightened risks of inflation or nationalization. The Fund may lose money due to political, economic and geographic events affecting a non-U.S. issuer or market. The Fund is specifically exposed to Asian Economic Risk and European Economic Risk.

Passive Investment Risk. The Fund is not actively managed and BFA does not attempt to take defensive positions under any market conditions, including declining markets.

Privatization Risk. Some countries in which the Fund invests have begun a process of privatizing certain entities and industries. Privatized entities may lose money or be re-nationalized.

Risk of Investing in Japan. The Japanese economy may be subject to considerable degrees of economic, political and social instability, which could have a negative impact on Japanese securities.

Securities Lending Risk. The Fund may engage in securities lending. Securities lending involves the risk that the Fund may lose money because the borrower of the Fund’s loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Security Risk. Some countries and regions in which the Fund invests have experienced security concerns. Incidents involving a country’s or region’s security may cause uncertainty in these markets and may adversely affect their economies and the Fund’s investments.

Small-Capitalization Companies Risk. The Fund invests in the securities of small-capitalization companies. Compared to mid- and large-capitalization companies, small-capitalization companies may be less stable and more susceptible to adverse developments and their securities may be more volatile and less liquid.

Tracking Error Risk. The performance of the Fund may diverge from that of the Underlying Index. Because the Fund employs a representative sampling strategy, the Fund may experience tracking error to a greater extent than a fund that seeks to replicate an index.

Valuation Risk. The value of the securities in the Fund’s portfolio may change on days when shareholders will not be able to purchase or sell the Fund’s shares.

1 After-tax returns in the table above are calculated using the historical highest individual U.S. federal marginal income tax rates and do not reflect the impact of state or local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown, and after-tax returns shown are not relevant to tax-exempt investors or investors who hold shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts (“IRAs”). Fund returns after taxes on distributions and sale of Fund shares are calculated assuming that an investor has sufficient capital gains of the same character from other investments to offset any capital losses from the sale of Fund shares. As a result, Fund returns after taxes on distributions and sale of Fund shares may exceed Fund returns before taxes and/or returns after taxes on distributions.

Management

Investment Adviser. BlackRock Fund Advisors.

Portfolio Managers. Rene Casis, Diane Hsiung and Greg Savage (the “Portfolio Managers”) are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager supervises a portfolio management team. Mr. Casis, Ms. Hsiung and Mr. Savage have been Portfolio Managers of the Fund since 2010, 2008 and 2008, respectively.

Purchase and Sale of Fund Shares

The Fund is an exchange-traded fund (commonly referred to as an “ETF”). Individual Fund shares may only be purchased and sold on a national securities exchange through a broker-dealer. The price of Fund shares is based on market price, and because ETF shares trade at market prices rather than NAV, shares may trade at a price greater than NAV (a premium) or less than NAV (a discount). The Fund will only issue or redeem shares that have been aggregated into blocks of 200,000 shares or multiples thereof (“Creation Units”) to authorized participants who have entered into agreements with the Fund’s distributor. The Fund generally will issue or redeem Creation Units in return for a designated portfolio of securities (and an amount of cash) that the Fund specifies each day.

Tax Information

The Fund intends to make distributions that may be taxable to you as ordinary income or capital gains, unless you are investing through a tax-deferred arrangement such as a 401(k) plan or an IRA.

Payments to Broker-Dealers and other Financial Intermediaries

If you purchase shares of the Fund through a broker-dealer or other financial intermediary (such as a bank), BFA or other related companies may pay the intermediary for marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems or other services related to the sale or promotion of the Fund. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.

More Information About the Fund

This Prospectus contains important information about investing in the Fund. Please read this Prospectus carefully before you make any investment decisions. Additional information regarding the Fund is available at www.iShares.com.

BFA is the investment adviser to the Fund. Shares of the Fund are listed for trading on NYSE Arca, Inc. (“NYSE Arca”). The market price for a share of the Fund may be different from the Fund’s most recent NAV.

ETFs are funds that trade like other publicly-traded securities. The Fund is designed to track an index. Similar to shares of an index mutual fund, each share of the Fund represents a partial ownership in an underlying portfolio of securities intended to track a market index. Unlike shares of a mutual fund, which can be bought and redeemed from the issuing fund by all shareholders at a price based on NAV, shares of the Fund may be purchased or redeemed directly from the Fund at NAV solely by authorized participants. Also unlike shares of a mutual fund, shares of the Fund are listed on a national securities exchange and trade in the secondary market at market prices that change throughout the day.

The Fund invests in a particular segment of the securities markets and seeks to track the performance of a securities index that generally is not representative of the market as a whole. The Fund is designed to be used as part of broader asset allocation strategies. Accordingly, an investment in the Fund should not constitute a complete investment program.

An index is a theoretical financial calculation while the Fund is an actual investment portfolio. The performance of the Fund and the Underlying Index may vary due to transaction costs, non-U.S. currency valuations, asset valuations, corporate actions (such as mergers and spin-offs), timing variances and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions (such as diversification requirements) that apply to the Fund but not to the Underlying Index or to the use of representative sampling. “Tracking error” is the difference between the performance (return) of the Fund’s portfolio and that of the Underlying Index. BFA expects that, over time, the Fund’s tracking error will not exceed 5%. Because the Fund uses a representative sampling indexing strategy, it can be expected to have a larger tracking error than if it used a replication indexing strategy. “Replication” is an indexing strategy in which a fund invests in substantially all of the securities in its underlying index in approximately the same proportions as in the underlying index.

An investment in the Fund is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, BFA or any of its affiliates.

The Fund’s investment objective and the Underlying Index may be changed without shareholder approval.

A Further Discussion of Principal Risks

The Fund is subject to various risks, including the principal risks noted below, any of which may adversely affect the Fund’s NAV, trading price, yield, total return and ability to meet its investment objective. You could lose all or part of your investment in the Fund, and the Fund could underperform other investments.

Asian Economic Risk. Certain Asian economies have experienced over-extension of credit, currency devaluations and restrictions, high unemployment, high inflation, decreased exports and economic recessions. Economic events in any one Asian country may have a significant economic effect on the entire Asian region, as well as on major trading partners outside Asia, and any adverse event in the Asian markets may have a significant adverse effect on other Asian economies.

Asset Class Risk. The securities in the Underlying Index or in the Fund’s portfolio may underperform the returns of other securities or indexes that track other countries, groups of countries, regions, industries, groups of industries, markets, asset classes or sectors. Various types of securities or indexes tend to experience cycles of outperformance and underperformance in comparison to the general securities markets.

Concentration Risk. To the extent that the Fund’s portfolio reflects the Underlying Index’s concentration in the securities of a particular issuer or issuers in a particular country, group of countries, region, market, industry, group of industries, sector or asset class, the Fund may be adversely affected by the performance of those securities, may be subject to increased price volatility and may be more susceptible to adverse economic, market, political or regulatory occurrences affecting that issuer, country, group of countries, region, market, industry, group of industries, sector or asset class.

Consumer Discretionary Sector Risk. The success of consumer product manufacturers and retailers is tied closely to the performance of domestic and international economies, interest rates, exchange rates, competition, consumer confidence, changes in demographics and consumer preferences. Companies in the consumer discretionary sector depend heavily on disposable household income and consumer spending, and may be strongly affected by social trends and marketing campaigns. These companies may be subject to severe competition, which may have an adverse impact on their profitability.

Currency Risk. Because the Fund’s NAV is determined on the basis of the U.S. dollar, investors may lose money if the currency of a non-U.S. market in which the Fund invests depreciates against the U.S. dollar, even if the local currency value of the Fund’s holdings in that market increases.

Equity Securities Risk. The Fund invests in equity securities, which are subject to changes in value that may be attributable to market perception of a particular issuer or to general stock market fluctuations that affect all issuers. Investments in equity securities may be more volatile than investments in other asset classes.

European Economic Risk. The Economic and Monetary Union of the European Union (the “EU”) requires member countries to comply with restrictions on inflation rates,

deficits, interest rates, debt levels and fiscal and monetary controls, each of which may significantly affect every country in Europe. Decreasing imports or exports, changes in governmental or EU regulations on trade, changes in the exchange rate of the euro, the default or threat of default by an EU member country on its sovereign debt, and/or an economic recession in an EU member country may have a significant adverse effect on the economies of EU member countries and on major trading partners outside Europe. The European financial markets have recently experienced volatility and have been adversely affected by concerns about economic downturns, credit rating downgrades, rising government debt levels and possible default on or restructuring of government debt in several European countries, including Greece, Ireland, Italy, Portugal and Spain. A default or debt restructuring by any European country would adversely impact holders of that country’s debt, and sellers of credit default swaps linked to that country’s creditworthiness, which may be located in countries other than those listed in the previous sentence. These events have adversely affected the value and exchange rate of the euro and may continue to significantly affect the economies of every country in Europe, including EU member countries that do not use the euro and non-EU member countries.

Financial Sector Risk. Companies in the financial sector of an economy are often subject to governmental regulation and, recently, government intervention and the potential for additional regulation, which may adversely affect the scope of their activities, the prices they can charge and the amount of capital they must maintain. Governmental regulation may change frequently and may have significant adverse consequences for companies in the financial sector, including effects not intended by such regulation. The impact of recent or future regulation in various countries on any individual financial company or on the sector as a whole cannot be predicted. Certain risks may impact the value of investments in the financial sector more severely than investments outside this sector, including the risks associated with companies that operate with substantial financial leverage. Companies in the financial sector may also be adversely affected by increases in interest rates and loan losses, decreases in the availability of money or asset valuations, credit rating downgrades and adverse conditions in other related markets. Over the past few years, the deterioration of the credit markets has impacted a broad range of mortgage, asset-backed, auction rate, sovereign debt and other markets, including U.S. and non-U.S. credit and interbank money markets, thereby affecting a wide range of financial institutions and markets. This situation has created instability in the financial markets and caused certain financial companies to incur large losses. Some financial companies have experienced declines in the valuations of their assets, taken actions to raise capital (such as the issuance of debt or equity securities), or even ceased operations. Some financial companies have borrowed significant amounts of capital from governments and may face future government-imposed restrictions on their businesses or increased government intervention. These actions have caused the securities of many financial companies to decline in value. Insurance companies, in particular, may be subject to severe price competition, which may have an adverse impact on their profitability.

Geographic Risk. Some markets in which the Fund invests are located in parts of the world that have historically been prone to natural disasters, such as earthquakes, volcanoes, droughts, floods, hurricanes and tsunamis, and are economically sensitive

to environmental events. Any natural or other disaster could have a significant adverse impact on the economies of these geographic areas, causing an adverse impact on the Fund’s investments in the affected region.

Industrials Sector Risk. The stock prices of companies in the industrials sector are affected by supply and demand, both for their specific product or service and for industrials sector products in general. The products of manufacturing companies may face obsolescence due to rapid technological developments and frequent new product introduction. Government regulations, world events, economic conditions and exchange rates affect the performance of companies in the industrials sector. Companies in the industrials sector may be adversely affected by liability for environmental damage, product liability claims and exchange rates. The industrials sector may also be adversely affected by changes or trends in commodity prices, which may be influenced by unpredictable factors.

Issuer Risk. The performance of the Fund depends on the performance of individual securities to which the Fund has exposure. Any issuer of these securities may perform poorly, causing the value of its securities to decline. Poor performance may be caused by poor management decisions, competitive pressures, changes in technology, expiration of patent protection, disruptions in supply, labor problems or shortages, corporate restructurings, fraudulent disclosures or other factors. Issuers may, in times of distress or at their own discretion, decide to reduce or eliminate dividends, which may also cause their stock prices to decline.

Management Risk. The Fund may not fully replicate the Underlying Index and may hold securities not included in the Underlying Index. As a result, the Fund is subject to the risk that BFA’s investment management strategy, the implementation of which is subject to a number of constraints, may not produce the intended results.

Market Risk. The Fund could lose money due to short-term market movements and over longer periods during market downturns. Securities may decline in value due to factors affecting securities markets generally or particular industries represented in the markets. The value of a security may decline due to general market conditions, economic trends or events that are not specifically related to the issuer of the security or to factors that affect a particular industry or industries. During a general downturn in the securities markets, multiple asset classes may be negatively affected.

Market Trading Risk

Absence of Active Market. Although shares of the Fund are listed for trading on one or more stock exchanges, there can be no assurance that an active trading market for such shares will develop or be maintained.

Risk of Secondary Listings. The Fund’s shares may be listed or traded on U.S. and non-U.S. stock exchanges other than the U.S. stock exchange where the Fund’s primary listing is maintained. There can be no assurance that the Fund’s shares will continue to trade on any such stock exchange or in any market or that the Fund’s shares will continue to meet the requirements for listing or trading on any exchange or in any market. The Fund’s shares may be less actively traded in certain markets than others, and investors are subject to the execution and settlement risks and market standards of the market where they or their broker direct their trades for execution. Certain

information available to investors who trade Fund shares on a U.S. stock exchange during regular U.S. market hours may not be available to investors who trade in other markets, which may result in secondary market prices in such markets being less efficient.

Secondary Market Trading Risk. Shares of the Fund may trade in the secondary market at times when the Fund does not accept orders to purchase or redeem shares. At such times, shares may trade in the secondary market with more significant premiums or discounts than might be experienced at times when the Fund accepts purchase and redemption orders.

Secondary market trading in Fund shares may be halted by a stock exchange because of market conditions or other reasons. In addition, trading in Fund shares on a stock exchange or in any market may be subject to trading halts caused by extraordinary market volatility pursuant to “circuit breaker” rules on the stock exchange or market. There can be no assurance that the requirements necessary to maintain the listing or trading of Fund shares will continue to be met or will remain unchanged.

Shares of the Fund May Trade at Prices Other Than NAV. Shares of the Fund trade on stock exchanges at prices at, above or below their most recent NAV. The NAV of the Fund is calculated at the end of each business day and fluctuates with changes in the market value of the Fund’s holdings since the most recent calculation. The trading prices of the Fund’s shares fluctuate continuously throughout trading hours based on market supply and demand rather than NAV. The trading prices of the Fund’s shares may deviate significantly from NAV during periods of market volatility. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV. However, because shares can be created and redeemed in Creation Units at NAV (unlike shares of many closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their NAVs), BFA believes that large discounts or premiums to the NAV of the Fund are not likely to be sustained over the long-term. While the creation/redemption feature is designed to make it likely that the Fund’s shares normally will trade on stock exchanges at prices close to the Fund’s next calculated NAV, exchange prices are not expected to correlate exactly with the Fund’s NAV due to timing reasons as well as market supply and demand factors. In addition, disruptions to creations and redemptions or extreme market volatility may result in trading prices for shares of the Fund that differ significantly from its NAV.

Costs of Buying or Selling Fund Shares. Buying or selling Fund shares on an exchange involves two types of costs that apply to all securities transactions. When buying or selling shares of the Fund through a broker, you will likely incur a brokerage commission or other charges imposed by brokers as determined by that broker. In addition, you may incur the cost of the “spread” – that is, the difference between what investors are willing to pay for Fund shares (the “bid” price) and the price at which they are willing to sell Fund shares (the “ask” price). Because of the costs inherent in buying or selling Fund shares, frequent trading may detract significantly from investment results and an investment in Fund shares may not be advisable for investors who anticipate regularly making small investments.

Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers are subject to all of the risks of investing in the markets where such issuers are located, including heightened risks of inflation or nationalization and market fluctuations caused by economic and political developments. As a result of investing in non-U.S. securities, the Fund may be subject to increased risk of loss caused by any of the factors listed below:

  • Lower levels of liquidity and market efficiency;
  • Greater securities price volatility;
  • Exchange rate fluctuations and exchange controls;
  • Less availability of public information about issuers;
  • Limitations on foreign ownership of securities;
  • Imposition of withholding or other taxes;
  • Imposition of restrictions on the expatriation of the funds or other assets of the Fund;
  • Higher transaction and custody costs and delays in settlement procedures;
  • Difficulties in enforcing contractual obligations;
  • Lower levels of regulation of the securities market;
  • Weaker accounting, disclosure and reporting requirements; and
  • Legal principles related to corporate governance, directors’ fiduciary duties and liabilities and stockholders’ rights in markets in which the Fund invests may differ and/or may not be as extensive or protective as those that apply in the United States.

Passive Investment Risk. The Fund is not actively managed and may be affected by a general decline in market segments related to the Underlying Index. The Fund invests in securities included in, or representative of, the Underlying Index regardless of their investment merits. BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

Privatization Risk. Some countries in which the Fund invests have begun a process of privatizing certain entities and industries. In some instances, investors in newly privatized entities have suffered losses due to the inability of the newly privatized entities to adjust quickly to a competitive environment or changing regulatory and legal standards or, in some cases, due to re-nationalization of such privatized entities. There is no assurance that such losses will not recur.

Risk of Investing in Japan. Japan may be subject to political, economic, nuclear, and labor risks. Any of these risks, individually or in the aggregate, can impact an investment made in Japan.

  • Political Risk. Historically, Japan has had unpredictable national politics and may experience frequent political turnover. Future political developments may lead to changes in policy that might adversely affect the Fund’s investments.
  • Large Government Debt Risk. The Japanese economy faces several concerns, including a financial system with large levels of nonperforming loans, over-leveraged corporate balance sheets, extensive cross-ownership by major corporations, a changing corporate governance structure, and large government deficits. These issues may cause a slowdown of the Japanese economy.
  • Currency Risk. The Japanese yen has fluctuated widely at times and any increase in its value may cause a decline in exports that could weaken the economy.
  • Nuclear Risk. The nuclear power plant catastrophe in Japan in March of 2011 may have short-term and long-term effects on the nuclear energy industry, the extent of which are currently unknown.
  • Labor Risk. Japan has an aging workforce. It is a labor market that is undergoing fundamental structural changes, as traditional lifetime employment clashes with the need for increased labor mobility, which may adversely affect Japan’s economic competitiveness.
  • Geographic Risk. Natural disasters, such as earthquakes, could occur in Japan or surrounding areas and could negatively affect the Japanese economy, and, in turn, could negatively affect the Fund.

Securities Lending Risk. The Fund may engage in securities lending. Securities lending involves the risk that the Fund may lose money because the borrower of the Fund’s loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for the loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Security Risk. Some geographic areas in which the Fund invests have experienced acts of terrorism or strained international relations due to territorial disputes, historical animosities or other defense concerns. These situations may cause uncertainty in the markets of these geographic areas and may adversely affect the performance of their economies.

Small-Capitalization Companies Risk. Many of the companies in which the Fund invests are considered small-capitalization companies. Stock prices of small-capitalization companies may be more volatile than those of larger companies and, therefore, the Fund’s share price may be more volatile than those of funds that invest a larger percentage of their assets in stocks issued by mid- or large-capitalization companies. Stock prices of small-capitalization companies are generally more vulnerable than those of mid- or large-capitalization companies to adverse business and economic developments. Securities of small-capitalization companies may be thinly traded, making it difficult for the Fund to buy and sell them. In addition, small-capitalization companies are typically less financially stable than larger, more established companies and may depend on a small number of essential personnel, making them more vulnerable to loss of personnel. Small-capitalization companies also normally have less diverse product lines than mid- or large-capitalization companies and are more susceptible to adverse developments concerning their products.

Tracking Error Risk. Imperfect correlation between the Fund’s portfolio securities and those in the Underlying Index, rounding of prices, changes to the Underlying Index and regulatory requirements may cause tracking error, which is the divergence of the Fund’s performance from that of the Underlying Index. This risk may be heightened

during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Underlying Index does not. Because the Fund employs a representative sampling strategy, the Fund may experience tracking error to a greater extent than a fund that seeks to replicate an index.

Valuation Risk. Because non-U.S. exchanges may be open on days when the Fund does not price its shares, the value of the securities in the Fund’s portfolio may change on days when shareholders will not be able to purchase or sell the Fund’s shares. In addition, for purposes of calculating the Fund’s NAV, the value of assets denominated in non-U.S. currencies is converted into U.S. dollars using exchange rates deemed appropriate by BFA. This conversion may result in a difference between the prices used to calculate the Fund’s NAV and the prices used by the Underlying Index, which, in turn, could result in a difference between the Fund’s performance and the performance of the Underlying Index.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

Australasian Economic Risk. The economies of Australasia, which include Australia and New Zealand, are dependent on exports from the agricultural and mining sectors. This makes Australasian economies susceptible to fluctuations in the commodity markets. Australasian economies are also increasingly dependent on their growing service industries. Because the economies of Australasia are dependent on the economies of Asia, Europe and the United States as key trading partners and investors, reduction in spending by any of these trading partners on Australasian products and services, or negative changes in any of these economies, may cause an adverse impact on some or all of the Australasian economies.

Consumer Staples Sector Risk. The Fund invests in companies in the consumer staples sector. The consumer staples sector may be affected by the permissibility of using various food additives and production methods, marketing campaigns and other factors affecting consumer demand. Tobacco companies, in particular, may be adversely affected by new laws, regulations and litigation. The consumer staples sector may also be adversely affected by changes or trends in commodity prices, which may be influenced or characterized by unpredictable factors.

Health Care Sector Risk. The profitability of companies in the health care sector may be affected by extensive government regulations, restrictions on government reimbursement for medical expenses, rising costs of medical products and services, pricing pressure, an increased emphasis on outpatient services, limited number of products, industry innovation, changes in technologies and other market developments. Many health care companies are heavily dependent on patent protection. The expiration of patents may adversely affect the profitability of these companies. Many health care companies are subject to extensive litigation based on product liability and similar claims. Health care companies are subject to competitive forces that may make it difficult to raise prices and, in fact, may result in price discounting. Many new products in the health care sector may be subject to regulatory

approvals. The process of obtaining such approvals may be long and costly. Companies in the health care sector may be thinly capitalized and may be susceptible to product obsolescence.

Information Technology Sector Risk. Information technology companies face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Like other technology companies, information technology companies may have limited product lines, markets, financial resources or personnel. The products of information technology companies may face obsolescence due to rapid technological developments and frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Companies in the information technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies.

Materials Sector Risk. Companies in the materials sector could be adversely affected by commodity price volatility, exchange rates, import controls, increased competition, depletion of resources, technical progress, labor relations, exchange rates and government regulations, among other factors. Also, companies in the materials sector are at risk of liability for environmental damage and product liability claims. Production of materials may exceed demand as a result of market imbalances or economic downturns, leading to poor investment returns.

Portfolio Holdings Information

A description of the Trust’s policies and procedures with respect to the disclosure of the Fund’s portfolio securities is available in the Fund’s Statement of Additional Information (“SAI”). The top holdings of the Fund can be found at www.iShares.com. Fund fact sheets provide information regarding the Fund’s top holdings and may be requested by calling 1-800-iShares (1-800-474-2737).

Management

Investment Adviser. As investment adviser, BFA has overall responsibility for the general management and administration of the Trust. BFA provides an investment program for the Fund and manages the investment of the Fund’s assets. In managing the Fund, BFA may draw upon the research and expertise of its asset management affiliates with respect to certain portfolio securities. In seeking to achieve the Fund’s investment objective, BFA uses teams of portfolio managers, investment strategists and other investment specialists. This team approach brings together many disciplines and leverages BFA’s extensive resources.

Pursuant to the Investment Advisory Agreement between BFA and the Trust (entered into on behalf of the Fund), BFA is responsible for substantially all expenses of the Fund, except interest expenses, taxes, brokerage expenses, future distribution fees or expenses and extraordinary expenses.

For its investment advisory services to the Fund, BFA is entitled to receive a management fee from the Fund based on a percentage of the Fund’s average daily net assets, at the annual rate of 0.40%.

BFA is located at 400 Howard Street, San Francisco, CA 94105. It is a wholly owned subsidiary of BTC, which in turn is indirectly wholly-owned by BlackRock, Inc. (“BlackRock”). As of September 30, 2011, BTC and its affiliates, including BFA and BlackRock, provided investment advisory services for assets in excess of $3.35 trillion. BFA, BTC, BlackRock Execution Services, BlackRock and their affiliates deal, trade and invest for their own accounts in the types of securities in which the Fund may also invest.

A discussion regarding the basis for the Trust’s Board of Trustees’ (the “Board”) approval of the Investment Advisory Agreement with BFA is available in the Fund’s annual report for the period ended July 31.

Portfolio Managers. Rene Casis, Diane Hsiung and Greg Savage are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager is responsible for various functions related to portfolio management, including, but not limited to, investing cash inflows, coordinating with members of his or her portfolio management team to focus on certain asset classes, implementing investment strategy, researching and reviewing investment strategy and overseeing members of his or her portfolio management team that have more limited responsibilities.

Rene Casis has been employed by BFA (formerly, Barclays Global Fund Advisors (“BGFA”)) and BTC (formerly, Barclays Global Investors, N.A. (“BGI”)) as a senior portfolio manager since 2009. From 2005 to 2009, Mr. Casis was a trader at Barclays Capital. Prior to that, Mr. Casis was a portfolio manager from 2000 to 2005 for BGFA and BGI. Mr. Casis has been a Portfolio Manager of the Fund since 2010.

Diane Hsiung has been employed by BFA and BTC as a senior portfolio manager since 2007. Prior to that, Ms. Hsiung was a portfolio manager from 2002 to 2006 for BGFA and BGI. Ms. Hsiung has been a Portfolio Manager of the Fund since 2008.

Greg Savage has been employed by BFA and BTC as a senior portfolio manager since 2006. Prior to that, Mr. Savage was a portfolio manager from 2001 to 2006 for BGFA and BGI. Mr. Savage has been a Portfolio Manager of the Fund since 2008.

The Fund’s SAI provides additional information about the Portfolio Managers’ compensation, other accounts managed by the Portfolio Managers and the Portfolio Managers’ ownership (if any) of shares in the Fund.

Administrator, Custodian and Transfer Agent. State Street Bank and Trust Company (“State Street”) is the administrator, custodian and transfer agent for the Fund.

Conflicts of Interest. BFA wants you to know that there are certain entities with which BFA has relationships that may give rise to conflicts of interest, or the appearance of conflicts of interest. These entities include the following: BFA’s affiliates (including BlackRock and The PNC Financial Services Group, Inc., and each of their affiliates, directors, partners, trustees, managing members, officers and employees (collectively, the “Affiliates”)) and BlackRock’s significant shareholder, Barclays Bank PLC and its affiliates, including Barclays PLC (each, an “Entity” and together, the “Entities”).

The activities of BFA, the Affiliates and the Entities in the management of, or their interest in, their own accounts and other accounts they manage, may present conflicts of interest that could disadvantage the Fund and its shareholders. BFA and its Affiliates or the Entities provide investment management services to other funds and discretionary managed accounts that may follow an investment program similar to that of the Fund. BFA, its Affiliates and the Entities are involved worldwide with a broad spectrum of financial services and asset management activities and may engage in the ordinary course of business in activities in which their interests or the interests of their clients may conflict with those of the Fund. BFA, one or more of the Affiliates or the Entities acts, or may act, as an investor, investment banker, research provider, investment manager, financier, underwriter, advisor, market maker, trader, prime broker, lender, agent or principal, and have other direct and indirect interests, in securities, currencies and other instruments in which the Fund may directly or indirectly invest. Thus, it is likely that the Fund will have multiple business relationships with and will invest in, engage in transactions with, make voting decisions with respect to, or obtain services from, entities for which BFA, an Affiliate or an Entity performs or seeks to perform investment banking or other services.

BFA or one or more Affiliates or Entities may engage in proprietary trading and advise accounts and funds that have investment objectives similar to those of the Fund and/or that engage in and compete for transactions in the same types of securities, currencies and other instruments as the Fund, including in securities issued by other open-end and closed-end investment management companies, including investment companies that are affiliated with the Fund and BFA, to the extent permitted under the Investment Company Act of 1940, as amended (the “1940 Act”). The trading activities of BFA, these Affiliates and Entities are carried out without reference to positions held directly or indirectly by the Fund and may result in BFA, an Affiliate or an Entity having positions that are adverse to those of the Fund.

No Affiliate or Entity is under any obligation to share any investment opportunity, idea or strategy with the Fund. As a result, an Affiliate or an Entity may compete with the Fund for appropriate investment opportunities. As a result of this and several other factors, the results of the Fund’s investment activities may differ from those of an Affiliate or an Entity and of other accounts managed by an Affiliate or an Entity, and it is possible that the Fund could sustain losses during periods in which one or more Affiliates or Entities and other accounts achieve profits on their trading for proprietary or other accounts. The opposite result is also possible.

The Fund may, from time to time, enter into transactions in which BFA or an Affiliate’s or an Entity’s clients have an interest adverse to the Fund. Furthermore, transactions undertaken by Affiliate-advised clients may adversely impact the Fund. Transactions by one or more Affiliate- or Entity-advised clients or BFA may have the effect of diluting or otherwise disadvantaging the values, prices or investment strategies of the Fund.

An Entity may maintain securities indices as part of its product offerings. Index-based funds seek to track the performance of securities indices and may use the name of the index in the fund name. Index providers, including the Entities, may be paid licensing fees for use of their indices or index names. Entities will not be obligated to license their indices to BFA and its Affiliates, and BFA and its Affiliates will not be assured that

the terms of any index licensing agreement with the Entities will be as favorable as those terms offered to other index licensees.

The Fund’s activities may be limited because of regulatory restrictions applicable to one or more Affiliates or Entities, and/or their internal policies designed to comply with such restrictions. In addition, the Fund may invest in securities of companies with which an Affiliate or an Entity has or is trying to develop investment banking relationships or in which an Affiliate or an Entity has significant debt or equity investments. The Fund also may invest in securities of companies for which an Affiliate or an Entity provides or may some day provide research coverage. An Affiliate or an Entity may have business relationships with and purchase or distribute or sell services or products from or to distributors, consultants or others who recommend the Fund or who engage in transactions with or for the Fund, and may receive compensation for such services. The Fund may also make brokerage and other payments to Affiliates or Entities in connection with the Fund’s portfolio investment transactions.

Pursuant to a securities lending program approved by the Board, the Fund has retained an Affiliate of BFA to serve as the securities lending agent for the Fund to the extent that the Fund participates in the securities lending program. For these services, the lending agent may receive a fee from the Fund, including a fee based on the returns earned on the Fund’s investment of the cash received as collateral for any loaned securities. In addition, one or more Affiliates may be among the entities to which the Fund may lend its portfolio securities under the securities lending program.

The activities of BFA, the Affiliates or Entities may give rise to other conflicts of interest that could disadvantage the Fund and its shareholders. BFA has adopted policies and procedures designed to address these potential conflicts of interest. See the Fund’s SAI for further information.

Shareholder Information

Additional shareholder information, including how to buy and sell shares of the Fund, is available free of charge by calling toll-free: 1-800-iShares (1-800-474-2737) or visiting our website at www.iShares.com.

Buying and Selling Shares. Shares of the Fund may be acquired or redeemed directly from the Fund only in Creation Units or multiples thereof, as discussed in the Creations and Redemptions section of this Prospectus. Only an Authorized Participant (as defined in the Creations and Redemptions section) may engage in creation or redemption transactions directly with the Fund. Once created, shares of the Fund generally trade in the secondary market in amounts less than a Creation Unit.

Shares of the Fund are listed on a national securities exchange for trading during the trading day. Shares can be bought and sold throughout the trading day like shares of other publicly-traded companies. The Trust does not impose any minimum investment for shares of the Fund purchased on an exchange. The Fund’s shares trade under the trading symbol “SCZ.”

Buying or selling Fund shares on an exchange involves two types of costs that may apply to all securities transactions. When buying or selling shares of the Fund through a broker, you will likely incur a brokerage commission or other charges determined by

your broker. The commission is frequently a fixed amount and may be a significant proportional cost for investors seeking to buy or sell small amounts of shares. In addition, you may incur the cost of the “spread” – that is, any difference between the bid price and the ask price. The spread varies over time for shares of the Fund based on its trading volume and market liquidity, and is generally lower if the Fund has a lot of trading volume and market liquidity, and higher if the Fund has little trading volume and market liquidity.

The Board has adopted a policy of not monitoring for frequent purchases and redemptions of Fund shares (“frequent trading”) that appear to attempt to take advantage of a potential arbitrage opportunity presented by a lag between a change in the value of the Fund’s portfolio securities after the close of the primary markets for the Fund’s portfolio securities and the reflection of that change in the Fund’s NAV (“market timing”), because the Fund generally sells and redeems its shares directly through transactions that are in-kind and/or for cash, subject to the conditions described below under Creations and Redemptions. The Board has not adopted a policy of monitoring for other frequent trading activity because shares of the Fund are listed for trading on a national securities exchange.

The national securities exchange on which the Fund’s shares are listed is open for trading Monday through Friday and is closed on weekends and the following holidays: New Year’s Day, Martin Luther King, Jr. Day, Presidents’ Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day. The Fund’s primary listing exchange is NYSE Arca.

Section 12(d)(1) of the 1940 Act restricts investments by investment companies in the securities of other investment companies. Registered investment companies are permitted to invest in the Fund beyond the limits set forth in Section 12(d)(1), subject to certain terms and conditions set forth in SEC rules or in an SEC exemptive order issued to the Trust. In order for a registered investment company to invest in shares of the Fund beyond the limitations of Section 12(d)(1) pursuant to the exemptive relief obtained by the Trust, the registered investment company must enter into an agreement with the Trust.

Book Entry. Shares of the Fund are held in book-entry form, which means that no stock certificates are issued. The Depository Trust Company (“DTC”) or its nominee is the record owner of all outstanding shares of the Fund and is recognized as the owner of all shares for all purposes.

Investors owning shares of the Fund are beneficial owners as shown on the records of DTC or its participants. DTC serves as the securities depository for shares of the Fund. DTC participants include securities brokers and dealers, banks, trust companies, clearing corporations and other institutions that directly or indirectly maintain a custodial relationship with DTC. As a beneficial owner of shares, you are not entitled to receive physical delivery of stock certificates or to have shares registered in your name, and you are not considered a registered owner of shares. Therefore, to exercise any right as an owner of shares, you must rely upon the procedures of DTC and its participants. These procedures are the same as those that apply to any other securities that you hold in book-entry or “street name” form.

Share Prices. The trading prices of the Fund’s shares in the secondary market generally differ from the Fund’s daily NAV and are affected by market forces such as supply and demand, economic conditions and other factors. Information regarding the intraday value of shares of the Fund, also known as the “indicative optimized portfolio value” (“IOPV”), is disseminated every 15 seconds throughout the trading day by the national securities exchange on which the Fund’s shares are listed or by market data vendors or other information providers. The IOPV is based on the current market value of the securities and/or cash required to be deposited in exchange for a Creation Unit. The IOPV does not necessarily reflect the precise composition of the current portfolio of securities held by the Fund at a particular point in time or the best possible valuation of the current portfolio. Therefore, the IOPV should not be viewed as a “real-time” update of the Fund’s NAV, which is computed only once a day. The IOPV is generally determined by using both current market quotations and/or price quotations obtained from broker-dealers that may trade in the portfolio securities held by the Fund. The quotations of certain Fund holdings may not be updated during U.S. trading hours if such holdings do not trade in the United States. The Fund is not involved in, or responsible for, the calculation or dissemination of the IOPV and makes no representation or warranty as to its accuracy.

Determination of Net Asset Value. The NAV of the Fund normally is determined once daily Monday through Friday, generally as of the regularly scheduled close of business of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m., Eastern time) on each day that the NYSE is open for trading, based on prices at the time of closing provided that (a) any Fund assets or liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers (as detailed below) and (b) U.S. fixed income assets may be valued as of the announced closing time for trading in fixed income instruments in a particular market or exchange. The NAV of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets held by the Fund, and its liabilities, are determined pursuant to valuation policies and procedures approved by the Board. The Fund’s assets and liabilities are valued primarily on the basis of market quotations.

Equity investments are valued at market value, which is generally determined using the last reported official closing price or last trading price on the exchange or market on which the security is primarily traded at the time of valuation.

The Fund invests in foreign securities. Foreign currency exchange rates are generally determined as of 4:00 p.m., London time. Foreign securities owned by the Fund may trade on weekends or other days when the Fund does not price its shares. As a result, the Fund’s NAV may change on days when Authorized Participants will not be able to purchase or redeem Fund shares.

Generally, trading in foreign securities, U.S. government securities, money market instruments and certain fixed-income securities is substantially completed each day at various times prior to the close of business on the NYSE. The values of such securities used in computing the NAV of the Fund are determined as of such times.

When market quotations are not readily available or are believed by BFA to be unreliable, the Fund’s investments are valued at fair value. Fair value determinations are made by BFA in accordance with policies and procedures approved by the Fund’s Board. BFA may conclude that a market quotation is not readily available or is unreliable if a security or other asset or liability does not have a price source due to its lack of liquidity, if a market quotation differs significantly from recent price quotations or otherwise no longer appears to reflect fair value, where the security or other asset or liability is thinly traded, or where there is a significant event subsequent to the most recent market quotation. A “significant event” is an event that, in the judgment of BFA, is likely to cause a material change to the closing market price of the asset or liability held by the Fund. Foreign securities whose values are affected by volatility that occurs in U.S. markets on a trading day after the close of foreign securities markets may be fair valued.

Fair value represents a good faith approximation of the value of an asset or liability. The fair value of an asset or liability held by the Fund is the amount the Fund might reasonably expect to receive from the current sale of that asset or the cost to extinguish that liability in an arm’s-length transaction. Valuing the Fund’s investments using fair value pricing will result in prices that may differ from current market valuations and that may not be the price at which those investments could have been sold during the period in which the particular fair values were used. Use of fair value prices and certain current market valuations could result in a difference between the prices used to calculate the Fund’s NAV and the prices used by the Underlying Index, which, in turn, could result in a difference between the Fund’s performance and the performance of the Underlying Index.

The value of assets or liabilities denominated in non-U.S. currencies will be converted into U.S. dollars using exchange rates deemed appropriate by BFA as investment adviser. Use of a rate different from the rate used by the Index Provider may adversely affect the Fund’s ability to track the Underlying Index.

Dividends and Distributions

General Policies. Dividends from net investment income, if any, generally are declared and paid semi-annually by the Fund. Distributions of net realized securities gains, if any, generally are declared and paid once a year, but the Trust may make distributions on a more frequent basis for the Fund. The Trust reserves the right to declare special distributions if, in its reasonable discretion, such action is necessary or advisable to preserve its status as a regulated investment company (“RIC”) or to avoid imposition of income or excise taxes on undistributed income or realized gains.

Dividends and other distributions on shares of the Fund are distributed on a pro rata basis to beneficial owners of such shares. Dividend payments are made through DTC participants and indirect participants to beneficial owners then of record with proceeds received from the Fund.

Dividend Reinvestment Service. No dividend reinvestment service is provided by the Trust. Broker-dealers may make available the DTC book-entry Dividend Reinvestment Service for use by beneficial owners of the Fund for reinvestment of their dividend distributions. Beneficial owners should contact their broker to determine the

availability and costs of the service and the details of participation therein. Brokers may require beneficial owners to adhere to specific procedures and timetables. If this service is available and used, dividend distributions of both income and realized gains will be automatically reinvested in additional whole shares of the Fund purchased in the secondary market.

Taxes. As with any investment, you should consider how your investment in shares of the Fund will be taxed. The tax information in this Prospectus is provided as general information, based on current law. You should consult your own tax professional about the tax consequences of an investment in shares of the Fund.

Unless your investment in Fund shares is made through a tax-exempt entity or tax-deferred retirement account, such as an IRA, you need to be aware of the possible tax consequences when the Fund makes distributions or you sell Fund shares.

Taxes on Distributions. Distributions from the Fund’s net investment income (other than qualified dividend income), including distributions of income from securities lending and distributions out of the Fund’s net short-term capital gains, if any, are taxable to you as ordinary income. Distributions by the Fund of net long-term capital gains in excess of net short-term capital losses (capital gain dividends) are taxable to you as long-term capital gains, generally at a 15% tax rate (0% at certain income levels), regardless of how long you have held the Fund’s shares. Distributions by the Fund that qualify as qualified dividend income are taxable to you at long-term capital gain rates for taxable years beginning on or before December 31, 2012. The 15% and 0% tax rates expire for taxable years beginning after December 31, 2012. Maximum long-term capital gain income tax rates are scheduled to rise to 20% in 2013. Beginning in 2013, a 3.8% U.S. federal Medicare contribution tax will be imposed on “net investment income,” including interest, dividends, and capital gains, of U.S. individuals with income exceeding $200,000 (or $250,000 if married and filing jointly), and of estates and trusts.

Dividends will be qualified dividend income to you if they are attributable to qualified dividend income received by the Fund. Generally, qualified dividend income includes dividend income from taxable U.S. corporations and qualified non-U.S. corporations, provided that the Fund satisfies certain holding period requirements in respect of the stock of such corporations and has not hedged its position in the stock in certain ways. Substitute dividends received by the Fund with respect to dividends paid on securities lent out will not be qualified dividend income. For this purpose, a qualified non-U.S. corporation means any non-U.S. corporation that is eligible for benefits under a comprehensive income tax treaty with the United States, which includes an exchange of information program or if the stock with respect to which the dividend was paid is readily tradable on an established United States securities market. The term excludes a corporation that is a passive foreign investment company.

Dividends received by the Fund from a real estate investment trust (“REIT”) or another RIC generally are qualified dividend income only to the extent the dividend distributions are made out of qualified dividend income received by such REIT or RIC. It is expected that dividends received by the Fund from a REIT and distributed to a shareholder generally will be taxable to the shareholder as ordinary income.

For a dividend to be treated as qualified dividend income, the dividend must be received with respect to a share of stock held without being hedged by the Fund, and with respect to a share of the Fund held without being hedged by you, for 61 days during the 121-day period beginning at the date which is 60 days before the date on which such share becomes ex-dividend with respect to such dividend or, in the case of certain preferred stock, 91 days during the 181-day period beginning 90 days before such date.

If your Fund shares are loaned out pursuant to a securities lending arrangement, you may lose the ability to use foreign tax credits passed through by the Fund or to treat Fund dividends paid while the shares are held by the borrower as qualified dividend income.

In general, your distributions are subject to U.S. federal income tax for the year when they are paid. Certain distributions paid in January, however, may be treated as paid on December 31 of the prior year.

If the Fund’s distributions exceed current and accumulated earnings and profits, all or a portion of the distributions made in the taxable year may be recharacterized as a return of capital to shareholders. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and result in a higher capital gain or lower capital loss when those shares on which the distribution was received are sold. Once a shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain, if the shareholder holds shares of the Fund as capital assets.

If you are neither a resident nor a citizen of the United States or if you are a non-U.S. entity, the Fund’s ordinary income dividends (which include distributions of net short-term capital gains) will generally be subject to a 30% U.S. withholding tax, unless a lower treaty rate applies, provided that withholding tax will generally not apply to any gain or income realized by a non-U.S. shareholder in respect of any distributions of long-term capital gains or upon the sale or other disposition of shares of the Fund.

A 30% withholding tax will be imposed on dividends paid after December 31, 2013, and redemption proceeds paid after December 31, 2014, to (i) foreign financial institutions including non-U.S. investment funds unless they agree to collect and disclose to the Internal Revenue Service (“IRS”) information regarding their direct and indirect U.S. account holders and (ii) certain other foreign entities, unless they certify certain information regarding their direct and indirect U.S. owners. To avoid withholding, foreign financial institutions will need to enter into agreements with the IRS that state that they will provide the IRS information, including the name, address and taxpayer identification number of direct and indirect U.S. account holders, comply with due diligence procedures with respect to the identification of U.S. accounts, report to the IRS certain information with respect to U.S. accounts maintained, agree to withhold tax on certain payments made to non-compliant foreign financial institutions or to account holders who fail to provide the required information, and determine certain other information as to their account holders. Other foreign entities will need to provide the name, address, and taxpayer identification number of each substantial U.S. owner or certifications of no substantial U.S. ownership unless certain exceptions apply.

Dividends, interest and capital gains earned by the Fund with respect to non-U.S. securities may give rise to withholding and other taxes imposed by non-U.S. countries. Tax conventions between certain countries and the United States may reduce or eliminate such taxes. If more than 50% of the total assets of the Fund at the close of a year consists of non-U.S. stocks or securities, the Fund may “pass through” to you certain non-U.S. income taxes (including withholding taxes) paid by the Fund. This means that you would be considered to have received as an additional dividend your share of such non-U.S. taxes, but you may be entitled to either a corresponding tax deduction in calculating your taxable income, or, subject to certain limitations, a credit in calculating your U.S. federal income tax.

For purposes of foreign tax credits for U.S. shareholders of the Fund, foreign capital gains taxes may not produce associated foreign source income, thereby limiting a U.S. person’s ability to use such credits.

If you are a resident or a citizen of the United States, by law, back-up withholding will apply to your distributions and proceeds if you have not provided a taxpayer identification number or social security number and made other required certifications.

Taxes When Shares are Sold. Currently, any capital gain or loss realized upon a sale of Fund shares is generally treated as a long-term gain or loss if the shares have been held for more than one year. Any capital gain or loss realized upon a sale of Fund shares held for one year or less is generally treated as short-term gain or loss, except that any capital loss on the sale of shares held for six months or less is treated as long-term capital loss to the extent that capital gain dividends were paid with respect to such shares. Beginning in 2013, any such capital gains, including from sales of Fund shares or from capital gain dividends, will be included in “net investment income” for purposes of the 3.8% U.S. federal Medicare contribution tax mentioned above.

The foregoing discussion summarizes some of the consequences under current U.S. federal tax law of an investment in the Fund. It is not a substitute for personal tax advice. You may also be subject to state and local taxation on Fund distributions and sales of shares. Consult your personal tax adviser about the potential tax consequences of an investment in shares of the Fund under all applicable tax laws.

Creations and Redemptions. Prior to trading in the secondary market, shares of the Fund are “created” at NAV by market makers, large investors and institutions only in block-size Creation Units of 200,000 shares or multiples thereof. Each “creator” or “Authorized Participant” enters into an authorized participant agreement with the Fund’s distributor, SEI Investments Distribution Co. (the “Distributor”). Only an Authorized Participant may create or redeem Creation Units directly with the Fund. A creation transaction, which is subject to acceptance by the transfer agent, generally takes place when an Authorized Participant deposits into the Fund a designated portfolio of securities and a specified amount of cash approximating the holdings of the Fund in exchange for a specified number of Creation Units. To the extent practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund.

Similarly, shares can be redeemed only in Creation Units, generally for a designated portfolio of securities and a specified amount of cash held by the Fund (“Fund

Securities”). Except when aggregated in Creation Units, shares are not redeemable by the Fund. The prices at which creations and redemptions occur are based on the next calculation of NAV after an order is received in a form described in the authorized participant agreement.

The Fund intends to comply with the U.S. federal securities laws in accepting securities for deposit and satisfying redemptions with redemption securities by, among other means, assuring that any securities accepted for deposit and any securities used to satisfy redemption requests will be sold in transactions that would be exempt from registration under the Securities Act of 1933, as amended (the “1933 Act”). Further, an Authorized Participant that is not a “qualified institutional buyer,” as such term is defined under Rule 144A of the 1933 Act, will not be able to receive Fund Securities that are restricted securities eligible for resale under Rule 144A.

Creations and redemptions must be made through a firm that is either a member of the Continuous Net Settlement System of the National Securities Clearing Corporation or a DTC participant and has executed an agreement with the Distributor with respect to creations and redemptions of Creation Unit aggregations. Information about the procedures regarding creation and redemption of Creation Units (including the cut-off times for receipt of creation and redemption orders) is included in the Fund’s SAI.

Because new shares may be created and issued on an ongoing basis, at any point during the life of the Fund a “distribution,” as such term is used in the 1933 Act, may be occurring. Broker-dealers and other persons are cautioned that some activities on their part may, depending on the circumstances, result in their being deemed participants in a distribution in a manner that could render them statutory underwriters and subject to the prospectus delivery and liability provisions of the 1933 Act. Any determination of whether one is an underwriter must take into account all the relevant facts and circumstances of each particular case.

Broker-dealers should also note that dealers who are not “underwriters” but are participating in a distribution (as contrasted to ordinary secondary transactions), and thus dealing with shares that are part of an “unsold allotment” within the meaning of Section 4(3)(C) of the 1933 Act, would be unable to take advantage of the prospectus delivery exemption provided by Section 4(3) of the 1933 Act. For delivery of prospectuses to exchange members, the prospectus delivery mechanism of Rule 153 under the 1933 Act is available only with respect to transactions on a national securities exchange.

Costs Associated with Creations and Redemptions. Authorized Participants are charged standard creation and redemption transaction fees to offset transfer and other transaction costs associated with the issuance and redemption of Creation Units. The standard creation and redemption transaction fees are set forth in the table below. The standard creation transaction fee is charged to the Authorized Participant on the day such Authorized Participant creates a Creation Unit, and is the same regardless of the number of Creation Units purchased by the Authorized Participant on the applicable business day. Similarly, the standard redemption transaction fee is charged to the Authorized Participant on the day such Authorized Participant redeems a Creation Unit, and is the same regardless of the number of Creation Units redeemed by the Authorized Participant on the applicable business day. Creations and

redemptions for cash (when cash creations and redemptions (in whole or in part) are available or specified) are also subject to an additional charge (up to the maximum amounts shown in the table below). This charge is intended to compensate for brokerage, tax, foreign exchange, execution, market impact and other costs and expenses related to cash transactions. Investors who use the services of a broker or other financial intermediary may pay fees for such services.

The following table shows, as of September 30, 2011, the approximate value of one Creation Unit, standard fees and maximum additional charges for creations and redemptions (as described above):

Householding. Householding is an option available to certain Fund investors. Householding is a method of delivery, based on the preference of the individual investor, in which a single copy of certain shareholder documents can be delivered to investors who share the same address, even if their accounts are registered under different names. Please contact your broker-dealer if you are interested in enrolling in householding and receiving a single copy of prospectuses and other shareholder documents, or if you are currently enrolled in householding and wish to change your householding status.

Distribution

The Distributor distributes Creation Units for the Fund on an agency basis. The Distributor does not maintain a secondary market in shares of the Fund. The Distributor has no role in determining the policies of the Fund or the securities that are purchased or sold by the Fund. The Distributor’s principal address is One Freedom Valley Drive, Oaks, PA 19456.

In addition, BFA or its Affiliates make payments to broker-dealers, banks or other financial intermediaries (together, “intermediaries”) related to marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems, or their making shares of the Fund and certain other iShares funds available to their customers. Such payments, which may be significant to the intermediary, are not made by the Fund. Rather, such payments are made by BFA or its Affiliates from their own resources, which come directly or indirectly in part from fees paid by the iShares funds complex. Payments of this type are sometimes referred to as revenue-sharing payments. A financial intermediary may make decisions about which investment options it recommends or makes available, or the level of services provided, to its customers based on the revenue-sharing payments it is eligible to receive. Therefore, such payments to an intermediary create

Financial Highlights

The financial highlights table is intended to help investors understand the Fund’s financial performance since inception. Certain information reflects financial results for a single share of the Fund. The total returns in the table represent the rate that an investor would have earned (or lost) on an investment in the Fund, assuming reinvestment of all dividends and distributions. This information has been audited by PricewaterhouseCoopers LLP, whose report is included, along with the Fund’s financial statements, in the Fund’s Annual Report (available upon request).

Supplemental Information

I. Premium/Discount Information

The table that follows presents information about the differences between the daily market price on secondary markets for shares of the Fund and the Fund’s NAV. NAV is the price at which the Fund issues and redeems shares. It is calculated in accordance with the standard formula for valuing mutual fund shares. The price used to calculate market returns (“Market Price”) of the Fund generally is determined using the midpoint between the highest bid and the lowest offer on the primary securities exchange on which shares of the Fund are listed for trading, as of the time that the Fund’s NAV is calculated. The Fund’s Market Price may be at, above or below its NAV. The NAV of the Fund will fluctuate with changes in the value of its portfolio holdings. The Market Price of the Fund will fluctuate in accordance with changes in its NAV, as well as market supply and demand.

Premiums or discounts are the differences (expressed as a percentage) between the NAV and Market Price of the Fund on a given day, generally at the time the NAV is calculated. A premium is the amount that the Fund is trading above the reported NAV, expressed as a percentage of the NAV. A discount is the amount that the Fund is trading below the reported NAV, expressed as a percentage of the NAV.

The following information shows the frequency of distributions of premiums and discounts for the Fund for each full calendar quarter of 2010 through September 30, 2011.

Each line in the table shows the number of trading days in which the Fund traded within the premium/discount range indicated. The number of trading days in each premium/discount range is also shown as a percentage of the total number of trading days in the period covered by the table. All data presented here represents past performance, which cannot be used to predict future results.

II. Total Return Information

The table that follows presents information about the total returns of the Fund and the Underlying Index as of the fiscal year ended July 31, 2011.

“Average Annual Total Returns” represent the average annual change in value of an investment over the periods indicated. “Cumulative Total Returns” represent the total change in value of an investment over the period indicated.

The Fund’s NAV is the value of one share of the Fund as calculated in accordance with the standard formula for valuing mutual fund shares. The NAV return is based on the NAV of the Fund and the market return is based on the Market Price of the Fund. Market Price is determined by using the midpoint between the highest bid and the lowest offer on the primary stock exchange on which shares of the Fund are listed for trading, as of the time that the Fund’s NAV is calculated. Since shares of the Fund did not trade in the secondary market until after the Fund’s inception, for the period from inception to the first day of secondary market trading in shares of the Fund, the NAV of the Fund is used as a proxy for the Market Price to calculate market returns. Market and NAV returns assume that dividends and capital gain distributions have been reinvested in the Fund at Market Price and NAV, respectively.

An index is a statistical composite that tracks a specified financial market or sector. Unlike the Fund, the Underlying Index does not actually hold a portfolio of securities and therefore does not incur the expenses incurred by the Fund. These expenses negatively impact the performance of the Fund. Also, market returns do not include brokerage commissions that may be payable on secondary market transactions. If brokerage commissions were included, market returns would be lower. The returns shown in the following table do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption or sale of Fund shares. The investment return and principal value of shares of the Fund will vary with changes in market conditions. Shares of the Fund may be worth more or less than their original cost when they are redeemed or sold in the market. The Fund’s past performance is no guarantee of future results.

Fund Overview

iSHARES® MSCI EAFE VALUE INDEX FUND

Ticker: EFV Stock Exchange: NYSE Arca

Investment Objective

The iShares MSCI EAFE Value Index Fund (the “Fund”) seeks investment results that correspond generally to the price and yield performance, before fees and expenses, of the MSCI EAFE® Value Index (the “Underlying Index”).

Fees and Expenses

The following table describes the fees and expenses that you will incur if you own shares of the Fund. The investment advisory agreement between iShares Trust (the “Trust”) and BlackRock Fund Advisors (“BFA”) (the “Investment Advisory Agreement”) provides that BFA will pay all operating expenses of the Fund, except interest expenses, taxes, brokerage expenses, future distribution fees or expenses, and extraordinary expenses.

You may also incur usual and customary brokerage commissions when buying or selling shares of the Fund, which are not reflected in the example that follows:

Expenses
0.40% None None 0.40%

Example. This Example is intended to help you compare the cost of owning shares of the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

5 Years
10 Years

Portfolio Turnover. The Fund may pay transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 29% of the average value of its portfolio.

Principal Investment Strategies

The Underlying Index is a subset of the MSCI EAFE® Index and constituents of the Underlying Index include securities from Europe, Australasia and the Far East. The Underlying Index generally represents approximately 50% of the free float-adjusted market capitalization of the MSCI EAFE® Index and consists of those securities classified by MSCI as most representing the value style. Securities classified as value style generally tend to have higher book value to price ratios, higher forward earnings to price ratios, higher dividend yields and lower forecasted earnings growth rates than securities representing the growth style. MSCI uses a specialized framework to attribute both value and growth style characteristics to each security within the MSCI EAFE® Index. Each security is evaluated based on certain value factors and growth factors, which are then used to calculate a value score and growth score. Based upon these two scores, MSCI determines the extent to which each security is assigned to the value or growth style. It is possible for a single security to have representation in both the value and growth style indexes, however, no more than 100% of a security’s float-adjusted market capitalization will be included within the combined style framework.

BFA uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to “beat” the index it tracks and does not seek temporary defensive positions when markets decline or appear overvalued.

Indexing may eliminate the chance that the Fund will substantially outperform the Underlying Index but also may reduce some of the risks of active management, such as poor security selection. Indexing seeks to achieve lower costs and better after-tax performance by keeping portfolio turnover low in comparison to actively managed investment companies.

BFA uses a representative sampling indexing strategy to manage the Fund. “Representative sampling” is an indexing strategy that involves investing in a representative sample of securities that collectively has an investment profile similar to the Underlying Index. The securities selected are expected to have, in the aggregate, investment characteristics (based on factors such as market capitalization and industry weightings), fundamental characteristics (such as return variability and yield) and liquidity measures similar to those of the Underlying Index. The Fund may or may not hold all of the securities in the Underlying Index.

The Fund generally invests at least 90% of its assets in securities of the Underlying Index and in depositary

S-2   


Table Of Contents



receipts representing securities of the Underlying Index. The Fund may invest the remainder of its assets in securities not included in the Underlying Index, but which BFA believes will help the Fund track the Underlying Index and in other investments including futures contracts, options on futures contracts, options and swaps as well as cash and cash equivalents, including shares of money market funds advised by BFA or its affiliates.

The Fund may lend securities representing up to one-third of the value of the Fund’s total assets (including the value of the collateral received).

The Underlying Index is sponsored by an organization (the “Index Provider”) that is independent of the Fund and BFA. The Index Provider determines the composition and relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index. The Fund’s Index Provider is MSCI Inc. (“MSCI”).

Industry Concentration Policy. The Fund will concentrate its investments (i.e., hold 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. For purposes of this limitation, securities of the U.S. government (including its agencies and instrumentalities) and repurchase agreements collateralized by U.S. government securities are not considered to be issued by members of any industry.

Summary of Principal Risks

As with any investment, you could lose all or part of your investment in the Fund, and the Fund’s performance could trail that of other investments. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund’s net asset value per share (“NAV”), trading price, yield, total return and ability to meet its investment objective.

Asset Class Risk. Securities in the Underlying Index or in the Fund’s portfolio may underperform in comparison to the general securities markets or other asset classes.

Concentration Risk. To the extent that the Fund’s investments are concentrated in a particular issuer, region, country, market, industry or asset class, the Fund may be susceptible to loss due to adverse occurrences affecting that issuer, region, country, market, industry or asset class.

Currency Risk. Because the Fund’s NAV is determined in U.S. dollars, the Fund’s NAV could decline if the currency of a non-U.S. market in which the Fund invests depreciates against the U.S. dollar.

Energy Sector Risk. The value of securities issued by companies in the energy sector may decline for many reasons, including, without limitation, changes in commodity prices, government regulations, energy conservation efforts and potential civil liabilities.

Equity Securities Risk. Equity securities are subject to changes in value and their values may be more volatile than other asset classes.

Financial Sector Risk. Performance of companies in the financial sector may be adversely impacted by many factors, including, among others, government

S-3   


Table Of Contents



regulations, economic conditions, credit rating downgrades, changes in interest rates, and decreased liquidity in credit markets. This sector has experienced significant losses in the recent past, and the impact of more stringent capital requirements and of recent or future regulation on any individual financial company or on the sector as a whole cannot be predicted.

Geographic Risk. A natural or other disaster could occur in a geographic region in which the Fund invests, which could affect the economy or particular business operations of companies in the specific geographic region, causing an adverse impact on the Fund’s investments in the affected region.

Health Care Sector Risk. The health care sector may be affected by government regulations and government health care programs, increases or decreases in the cost of medical products and services and product liability claims, among other factors. Many health care companies are heavily dependent on patent protection and the expiration of a patent may adversely affect their profitability. Health care companies are subject to competitive forces that may result in price discounting, and may be thinly capitalized and susceptible to product obsolescence.

Issuer Risk. Fund performance depends on the performance of individual securities to which the Fund has exposure. Changes to the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA’s investment management strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares, losses from trading in secondary markets, periods of high volatility and disruption in the creation/redemption process of the Fund. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV.

Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers are subject to the risks associated with investing in those non-U.S. markets, such as heightened risks of inflation or nationalization. The Fund may lose money due to political, economic and geographic events affecting a non-U.S. issuer or market. The Fund is specifically exposed to Asian Economic Risk and European Economic Risk.

Passive Investment Risk. The Fund is not actively managed and BFA does not attempt to take defensive positions under any market conditions, including declining markets.

Privatization Risk. Some countries in which the Fund invests have begun a process of privatizing certain entities and industries. Privatized entities may lose money or be re-nationalized.

Risk of Investing in Japan. The Japanese economy may be subject to considerable degrees of economic, political and social instability, which

S-4   


Table Of Contents



could have a negative impact on Japanese securities.

Securities Lending Risk. The Fund may engage in securities lending. Securities lending involves the risk that the Fund may lose money because the borrower of the Fund’s loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Security Risk. Some countries and regions in which the Fund invests have experienced security concerns. Incidents involving a country’s or region’s security may cause uncertainty in these markets and may adversely affect their economies and the Fund’s investments.

Telecommunications Sector Risk. Companies in the telecommunications sector may be affected by industry competition, substantial capital requirements, government regulation and obsolescence of telecommunications products and services due to technological advancement.

Tracking Error Risk. The performance of the Fund may diverge from that of the Underlying Index. Because the Fund employs a representative sampling strategy, the Fund may experience tracking error to a greater extent than a fund that seeks to replicate an index.

Valuation Risk. The value of the securities in the Fund’s portfolio may change on days when shareholders will not be able to purchase or sell the Fund’s shares.

Value Securities Risk. Securities issued by companies that may be perceived as undervalued may fail to appreciate for long periods of time and may never realize their full potential value.

1 After-tax returns in the table above are calculated using the historical highest individual U.S. federal marginal income tax rates and do not reflect the impact of state or local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown, and after-tax returns shown are not relevant to tax-exempt investors or investors who hold shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts (“IRAs”). Fund returns after taxes on distributions and sale of Fund shares are calculated assuming that an investor has sufficient capital gains of the same character from other investments to offset any capital losses from the sale of Fund shares. As a result, Fund returns after taxes on distributions and sale of Fund shares may exceed Fund returns before taxes and/or returns after taxes on distributions.

Management

Investment Adviser. BlackRock Fund Advisors.

Portfolio Managers. Rene Casis, Diane Hsiung and Greg Savage (the “Portfolio Managers”) are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager supervises a portfolio management team. Mr. Casis, Ms. Hsiung and Mr. Savage have been Portfolio Managers of the Fund since 2010, 2008 and 2008, respectively.

Purchase and Sale of Fund Shares

The Fund is an exchange-traded fund (commonly referred to as an “ETF”). Individual Fund shares may only be purchased and sold on a national securities exchange through a broker-dealer. The price of Fund shares is based on market price, and because ETF shares trade at market prices rather than NAV, shares may trade at a price greater than NAV (a premium) or less than NAV (a discount). The Fund will only issue or redeem shares that have been aggregated into blocks of 400,000 shares or multiples thereof (“Creation Units”) to authorized participants who have entered into agreements with the Fund’s distributor. The Fund generally will issue or redeem Creation Units in return for a designated portfolio of securities (and an amount of cash) that the Fund specifies each day.

Tax Information

The Fund intends to make distributions that may be taxable to you as ordinary income or capital gains, unless you are investing through a tax-deferred arrangement such as a 401(k) plan or an IRA.

Payments to Broker-Dealers and other Financial Intermediaries

If you purchase shares of the Fund through a broker-dealer or other financial intermediary (such as a bank), BFA or other related companies may pay the intermediary for marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems or other services related to the sale or promotion of the Fund. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.

Similar to shares of an index mutual fund, each share of the Fund represents a partial ownership in an underlying portfolio of securities intended to track a market index. Unlike shares of a mutual fund, which can be bought and redeemed from the issuing fund by all shareholders at a price based on NAV, shares of the Fund may be purchased or redeemed directly from the Fund at NAV solely by authorized participants. Also unlike shares of a mutual fund, shares of the Fund are listed on a national securities exchange and trade in the secondary market at market prices that change throughout the day.

The Fund invests in a particular segment of the securities markets and seeks to track the performance of a securities index that generally is not representative of the market as a whole. The Fund is designed to be used as part of broader asset allocation strategies. Accordingly, an investment in the Fund should not constitute a complete investment program.

An index is a theoretical financial calculation while the Fund is an actual investment portfolio. The performance of the Fund and the Underlying Index may vary due to transaction costs, non-U.S. currency valuations, asset valuations, corporate actions (such as mergers and spin-offs), timing variances and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions (such as diversification requirements) that apply to the Fund but not to the Underlying Index or to the use of representative sampling. “Tracking error” is the difference between the performance (return) of the Fund’s portfolio and that of the Underlying Index. BFA expects that, over time, the Fund’s tracking error will not exceed 5%. Because the Fund uses a representative sampling indexing strategy, it can be expected to have a larger tracking error than if it used a replication indexing strategy. “Replication” is an indexing strategy in which a fund invests in substantially all of the securities in its underlying index in approximately the same proportions as in the underlying index.

An investment in the Fund is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, BFA or any of its affiliates.

The Fund’s investment objective and the Underlying Index may be changed without shareholder approval.

A Further Discussion of Principal Risks

The Fund is subject to various risks, including the principal risks noted below, any of which may adversely affect the Fund’s NAV, trading price, yield, total return and ability to meet its investment objective. You could lose all or part of your investment in the Fund, and the Fund could underperform other investments.

Asian Economic Risk. Certain Asian economies have experienced over-extension of credit, currency devaluations and restrictions, high unemployment, high inflation, decreased exports and economic recessions. Economic events in any one Asian country may have a significant economic effect on the entire Asian region, as well as on major trading partners outside Asia, and any adverse event in the Asian markets may have a significant adverse effect on other Asian economies.

Asset Class Risk. The securities in the Underlying Index or in the Fund’s portfolio may underperform the returns of other securities or indexes that track other countries, groups of countries, regions, industries, groups of industries, markets, asset classes or sectors. Various types of securities or indexes tend to experience cycles of outperformance and underperformance in comparison to the general securities markets.

Concentration Risk. To the extent that the Fund’s portfolio reflects the Underlying Index’s concentration in the securities of a particular issuer or issuers in a particular country, group of countries, region, market, industry, group of industries, sector or asset class, the Fund may be adversely affected by the performance of those securities, may be subject to increased price volatility and may be more susceptible to adverse economic, market, political or regulatory occurrences affecting that issuer, country, group of countries, region, market, industry, group of industries, sector or asset class.

Currency Risk. Because the Fund’s NAV is determined on the basis of the U.S. dollar, investors may lose money if the currency of a non-U.S. market in which the Fund invests depreciates against the U.S. dollar, even if the local currency value of the Fund’s holdings in that market increases.

Energy Sector Risk. The energy sector is cyclical and highly dependent on commodities prices. The market values of companies in the energy sector are strongly affected by the levels and volatility of global energy prices, energy supply and demand, capital expenditures on exploration and production, energy conservation efforts, exchange rates and technological advances, among other factors. Companies in this sector may be subject to substantial government regulation and contractual fixed pricing, which may increase the cost of business and limit these companies’ earnings. A significant portion of their revenues depends on a relatively small number of customers, including governmental entities and utilities. As a result, governmental budget constraints may have a material adverse effect on the stock prices of companies in this industry. Energy companies may also operate in countries with less developed regulatory regimes or a history of expropriation, nationalization or other adverse policies. Energy companies also face a significant risk of civil liability from accidents resulting in injury or loss of life or property, pollution or other environmental mishaps, equipment malfunctions or mishandling of materials and a risk of loss from

terrorism and natural disasters. Any such event could have serious consequences for the general population of the area affected and result in a material adverse impact on the Fund’s portfolio and the performance of the Fund. Energy companies can be significantly affected by the supply of, and demand for, specific products (e.g., oil and natural gas) and services, exploration and production spending, government regulation, world events and general economic conditions.

Equity Securities Risk. The Fund invests in equity securities, which are subject to changes in value that may be attributable to market perception of a particular issuer or to general stock market fluctuations that affect all issuers. Investments in equity securities may be more volatile than investments in other asset classes.

European Economic Risk. The Economic and Monetary Union of the European Union (the “EU”) requires member countries to comply with restrictions on inflation rates, deficits, interest rates, debt levels and fiscal and monetary controls, each of which may significantly affect every country in Europe. Decreasing imports or exports, changes in governmental or EU regulations on trade, changes in the exchange rate of the euro, the default or threat of default by an EU member country on its sovereign debt, and/or an economic recession in an EU member country may have a significant adverse effect on the economies of EU member countries and on major trading partners outside Europe. The European financial markets have recently experienced volatility and have been adversely affected by concerns about economic downturns, credit rating downgrades, rising government debt levels and possible default on or restructuring of government debt in several European countries, including Greece, Ireland, Italy, Portugal and Spain. A default or debt restructuring by any European country would adversely impact holders of that country’s debt, and sellers of credit default swaps linked to that country’s creditworthiness, which may be located in countries other than those listed in the previous sentence. These events have adversely affected the value and exchange rate of the euro and may continue to significantly affect the economies of every country in Europe, including EU member countries that do not use the euro and non-EU member countries.

Financial Sector Risk. Companies in the financial sector of an economy are often subject to governmental regulation and, recently, government intervention and the potential for additional regulation, which may adversely affect the scope of their activities, the prices they can charge and the amount of capital they must maintain. Governmental regulation may change frequently and may have significant adverse consequences for companies in the financial sector, including effects not intended by such regulation. The impact of recent or future regulation in various countries on any individual financial company or on the sector as a whole cannot be predicted. Certain risks may impact the value of investments in the financial sector more severely than investments outside this sector, including the risks associated with companies that operate with substantial financial leverage. Companies in the financial sector may also be adversely affected by increases in interest rates and loan losses, decreases in the availability of money or asset valuations, credit rating downgrades and adverse conditions in other related markets. Over the past few years, the deterioration of the credit markets has impacted a broad range of mortgage, asset-backed, auction rate, sovereign debt and other markets, including U.S. and non-U.S. credit and interbank

money markets, thereby affecting a wide range of financial institutions and markets. This situation has created instability in the financial markets and caused certain financial companies to incur large losses. Some financial companies have experienced declines in the valuations of their assets, taken actions to raise capital (such as the issuance of debt or equity securities), or even ceased operations. Some financial companies have borrowed significant amounts of capital from governments and may face future government-imposed restrictions on their businesses or increased government intervention. These actions have caused the securities of many financial companies to decline in value. Insurance companies, in particular, may be subject to severe price competition, which may have an adverse impact on their profitability.

Geographic Risk. Some markets in which the Fund invests are located in parts of the world that have historically been prone to natural disasters, such as earthquakes, volcanoes, droughts, floods, hurricanes and tsunamis, and are economically sensitive to environmental events. Any natural or other disaster could have a significant adverse impact on the economies of these geographic areas, causing an adverse impact on the Fund’s investments in the affected region.

Health Care Sector Risk. The profitability of companies in the health care sector may be affected by extensive government regulations, restrictions on government reimbursement for medical expenses, rising costs of medical products and services, pricing pressure, an increased emphasis on outpatient services, limited number of products, industry innovation, changes in technologies and other market developments. Many health care companies are heavily dependent on patent protection. The expiration of patents may adversely affect the profitability of these companies. Many health care companies are subject to extensive litigation based on product liability and similar claims. Health care companies are subject to competitive forces that may make it difficult to raise prices and, in fact, may result in price discounting. Many new products in the health care sector may be subject to regulatory approvals. The process of obtaining such approvals may be long and costly. Companies in the health care sector may be thinly capitalized and may be susceptible to product obsolescence.

Issuer Risk. The performance of the Fund depends on the performance of individual securities to which the Fund has exposure. Any issuer of these securities may perform poorly, causing the value of its securities to decline. Poor performance may be caused by poor management decisions, competitive pressures, changes in technology, expiration of patent protection, disruptions in supply, labor problems or shortages, corporate restructurings, fraudulent disclosures or other factors. Issuers may, in times of distress or at their own discretion, decide to reduce or eliminate dividends, which may also cause their stock prices to decline.

Management Risk. The Fund may not fully replicate the Underlying Index and may hold securities not included in the Underlying Index. As a result, the Fund is subject to the risk that BFA’s investment management strategy, the implementation of which is subject to a number of constraints, may not produce the intended results.

Market Risk. The Fund could lose money due to short-term market movements and over longer periods during market downturns. Securities may decline in value due to factors affecting securities markets generally or particular industries represented in

the markets. The value of a security may decline due to general market conditions, economic trends or events that are not specifically related to the issuer of the security or to factors that affect a particular industry or industries. During a general downturn in the securities markets, multiple asset classes may be negatively affected.

Market Trading Risk

Absence of Active Market. Although shares of the Fund are listed for trading on one or more stock exchanges, there can be no assurance that an active trading market for such shares will develop or be maintained.

Risk of Secondary Listings. The Fund’s shares may be listed or traded on U.S. and non-U.S. stock exchanges other than the U.S. stock exchange where the Fund’s primary listing is maintained. There can be no assurance that the Fund’s shares will continue to trade on any such stock exchange or in any market or that the Fund’s shares will continue to meet the requirements for listing or trading on any exchange or in any market. The Fund’s shares may be less actively traded in certain markets than others, and investors are subject to the execution and settlement risks and market standards of the market where they or their broker direct their trades for execution. Certain information available to investors who trade Fund shares on a U.S. stock exchange during regular U.S. market hours may not be available to investors who trade in other markets, which may result in secondary market prices in such markets being less efficient.

Secondary Market Trading Risk. Shares of the Fund may trade in the secondary market at times when the Fund does not accept orders to purchase or redeem shares. At such times, shares may trade in the secondary market with more significant premiums or discounts than might be experienced at times when the Fund accepts purchase and redemption orders.

Secondary market trading in Fund shares may be halted by a stock exchange because of market conditions or other reasons. In addition, trading in Fund shares on a stock exchange or in any market may be subject to trading halts caused by extraordinary market volatility pursuant to “circuit breaker” rules on the stock exchange or market. There can be no assurance that the requirements necessary to maintain the listing or trading of Fund shares will continue to be met or will remain unchanged.

Shares of the Fund May Trade at Prices Other Than NAV. Shares of the Fund trade on stock exchanges at prices at, above or below their most recent NAV. The NAV of the Fund is calculated at the end of each business day and fluctuates with changes in the market value of the Fund’s holdings since the most recent calculation. The trading prices of the Fund’s shares fluctuate continuously throughout trading hours based on market supply and demand rather than NAV. The trading prices of the Fund’s shares may deviate significantly from NAV during periods of market volatility. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV. However, because shares can be created and redeemed in Creation Units at NAV (unlike shares of many closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their NAVs), BFA believes that large discounts or premiums to the NAV of the Fund are not likely to be sustained over the long-term. While the creation/redemption feature is

designed to make it likely that the Fund’s shares normally will trade on stock exchanges at prices close to the Fund’s next calculated NAV, exchange prices are not expected to correlate exactly with the Fund’s NAV due to timing reasons as well as market supply and demand factors. In addition, disruptions to creations and redemptions or extreme market volatility may result in trading prices for shares of the Fund that differ significantly from its NAV.

Costs of Buying or Selling Fund Shares. Buying or selling Fund shares on an exchange involves two types of costs that apply to all securities transactions. When buying or selling shares of the Fund through a broker, you will likely incur a brokerage commission or other charges imposed by brokers as determined by that broker. In addition, you may incur the cost of the “spread” – that is, the difference between what investors are willing to pay for Fund shares (the “bid” price) and the price at which they are willing to sell Fund shares (the “ask” price). Because of the costs inherent in buying or selling Fund shares, frequent trading may detract significantly from investment results and an investment in Fund shares may not be advisable for investors who anticipate regularly making small investments.

Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers are subject to all of the risks of investing in the markets where such issuers are located, including heightened risks of inflation or nationalization and market fluctuations caused by economic and political developments. As a result of investing in non-U.S. securities, the Fund may be subject to increased risk of loss caused by any of the factors listed below:

  • Lower levels of liquidity and market efficiency;
  • Greater securities price volatility;
  • Exchange rate fluctuations and exchange controls;
  • Less availability of public information about issuers;
  • Limitations on foreign ownership of securities;
  • Imposition of withholding or other taxes;
  • Imposition of restrictions on the expatriation of the funds or other assets of the Fund;
  • Higher transaction and custody costs and delays in settlement procedures;
  • Difficulties in enforcing contractual obligations;
  • Lower levels of regulation of the securities market;
  • Weaker accounting, disclosure and reporting requirements; and
  • Legal principles related to corporate governance, directors’ fiduciary duties and liabilities and stockholders’ rights in markets in which the Fund invests may differ and/or may not be as extensive or protective as those that apply in the United States.

Passive Investment Risk. The Fund is not actively managed and may be affected by a general decline in market segments related to the Underlying Index. The Fund invests in securities included in, or representative of, the Underlying Index regardless of their

investment merits. BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

Privatization Risk. Some countries in which the Fund invests have begun a process of privatizing certain entities and industries. In some instances, investors in newly privatized entities have suffered losses due to the inability of the newly privatized entities to adjust quickly to a competitive environment or changing regulatory and legal standards or, in some cases, due to re-nationalization of such privatized entities. There is no assurance that such losses will not recur.

Risk of Investing in Japan. Japan may be subject to political, economic, nuclear, and labor risks. Any of these risks, individually or in the aggregate, can impact an investment made in Japan.

  • Political Risk. Historically, Japan has had unpredictable national politics and may experience frequent political turnover. Future political developments may lead to changes in policy that might adversely affect the Fund’s investments.
  • Large Government Debt Risk. The Japanese economy faces several concerns, including a financial system with large levels of nonperforming loans, over-leveraged corporate balance sheets, extensive cross-ownership by major corporations, a changing corporate governance structure, and large government deficits. These issues may cause a slowdown of the Japanese economy.
  • Currency Risk. The Japanese yen has fluctuated widely at times and any increase in its value may cause a decline in exports that could weaken the economy.
  • Nuclear Risk. The nuclear power plant catastrophe in Japan in March of 2011 may have short-term and long-term effects on the nuclear energy industry, the extent of which are currently unknown.
  • Labor Risk. Japan has an aging workforce. It is a labor market that is undergoing fundamental structural changes, as traditional lifetime employment clashes with the need for increased labor mobility, which may adversely affect Japan’s economic competitiveness.
  • Geographic Risk. Natural disasters, such as earthquakes, could occur in Japan or surrounding areas and could negatively affect the Japanese economy, and, in turn, could negatively affect the Fund.

Securities Lending Risk. The Fund may engage in securities lending. Securities lending involves the risk that the Fund may lose money because the borrower of the Fund’s loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for the loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Security Risk. Some geographic areas in which the Fund invests have experienced acts of terrorism or strained international relations due to territorial disputes, historical animosities or other defense concerns. These situations may cause uncertainty in the markets of these geographic areas and may adversely affect the performance of their economies.

Telecommunications Sector Risk. The telecommunications sector is subject to extensive government regulation. The costs of complying with governmental regulations, delays or failure to receive required regulatory approvals, or the enactment of new adverse regulatory requirements may negatively affect the business of the telecommunications companies. Government actions around the world, specifically in the area of pre-marketing clearance of products and prices, can be arbitrary and unpredictable. Companies in the telecommunications sector may encounter distressed cash flows due to the need to commit substantial capital to meet increasing competition, particularly in formulating new products and services using new technology. Technological innovations may make the products and services of telecommunications companies obsolete.

Tracking Error Risk. Imperfect correlation between the Fund’s portfolio securities and those in the Underlying Index, rounding of prices, changes to the Underlying Index and regulatory requirements may cause tracking error, which is the divergence of the Fund’s performance from that of the Underlying Index. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Underlying Index does not. Because the Fund employs a representative sampling strategy, the Fund may experience tracking error to a greater extent than a fund that seeks to replicate an index.

Valuation Risk. Because non-U.S. exchanges may be open on days when the Fund does not price its shares, the value of the securities in the Fund’s portfolio may change on days when shareholders will not be able to purchase or sell the Fund’s shares. In addition, for purposes of calculating the Fund’s NAV, the value of assets denominated in non-U.S. currencies is converted into U.S. dollars using exchange rates deemed appropriate by BFA. This conversion may result in a difference between the prices used to calculate the Fund’s NAV and the prices used by the Underlying Index, which, in turn, could result in a difference between the Fund’s performance and the performance of the Underlying Index.

Value Securities Risk. Value securities are those issued by companies that may be perceived as undervalued. Value securities may fail to appreciate for long periods of time and may never realize their full potential value.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

Australasian Economic Risk. The economies of Australasia, which include Australia and New Zealand, are dependent on exports from the agricultural and mining sectors. This makes Australasian economies susceptible to fluctuations in the commodity markets. Australasian economies are also increasingly dependent on their growing service industries. Because the economies of Australasia are dependent on the economies of Asia, Europe and the United States as key trading partners and investors, reduction in spending by any of these trading partners on Australasian products and services, or negative changes in any of these economies, may cause an adverse impact on some or all of the Australasian economies.

Consumer Discretionary Sector Risk. The success of consumer product manufacturers and retailers is tied closely to the performance of domestic and international economies, interest rates, exchange rates, competition, consumer confidence, changes in demographics and consumer preferences. Companies in the consumer discretionary sector depend heavily on disposable household income and consumer spending, and may be strongly affected by social trends and marketing campaigns. These companies may be subject to severe competition, which may have an adverse impact on their profitability.

Industrials Sector Risk. The stock prices of companies in the industrials sector are affected by supply and demand, both for their specific product or service and for industrials sector products in general. The products of manufacturing companies may face obsolescence due to rapid technological developments and frequent new product introduction. Government regulations, world events, economic conditions and exchange rates affect the performance of companies in the industrials sector. Companies in the industrials sector may be adversely affected by liability for environmental damage, product liability claims and exchange rates. The industrials sector may also be adversely affected by changes or trends in commodity prices, which may be influenced by unpredictable factors.

Materials Sector Risk. Companies in the materials sector could be adversely affected by commodity price volatility, exchange rates, import controls, increased competition, depletion of resources, technical progress, labor relations, exchange rates and government regulations, among other factors. Also, companies in the materials sector are at risk of liability for environmental damage and product liability claims. Production of materials may exceed demand as a result of market imbalances or economic downturns, leading to poor investment returns.

Utilities Sector Risk. Deregulation is subjecting utility companies to greater competition and may adversely affect profitability. As deregulation allows utilities companies to diversify outside of their original geographic regions and their traditional lines of business, utilities companies may engage in riskier ventures. Companies in the utilities industry may have difficulty obtaining an adequate return on invested capital, raising capital, and financing large construction programs during periods of inflation or unsettled capital markets; face restrictions on operations and increased cost and delays attributable to environmental considerations and regulation; find that existing plants, equipment or products have been rendered obsolete by technical innovations; and be subject to increased costs because of the scarcity of certain fuels or the effects of man-made disasters. Existing and possible future regulations or legislation may make it difficult for utility companies to operate profitably. There is no assurance that regulatory authorities will, in the future, grant rate increases, or that such increases will be adequate to permit the payment of dividends on stocks issued by a utility company. Also, energy conservation and prolonged changes in climatic conditions may also have a significant impact on the revenues and expenses of utility companies. Government regulators monitor and control utility revenues and costs, and therefore may limit utility profits. In certain countries, regulatory authorities may also restrict

utility companies’ access to new markets, thereby diminishing these companies’ long-term prospects. The deregulation of certain utilities companies may eliminate restrictions on profits, but may also subject these companies to greater risks of loss.

Portfolio Holdings Information

A description of the Trust’s policies and procedures with respect to the disclosure of the Fund’s portfolio securities is available in the Fund’s Statement of Additional Information (“SAI”). The top holdings of the Fund can be found at www.iShares.com. Fund fact sheets provide information regarding the Fund’s top holdings and may be requested by calling 1-800-iShares (1-800-474-2737).

Management

Investment Adviser. As investment adviser, BFA has overall responsibility for the general management and administration of the Trust. BFA provides an investment program for the Fund and manages the investment of the Fund’s assets. In managing the Fund, BFA may draw upon the research and expertise of its asset management affiliates with respect to certain portfolio securities. In seeking to achieve the Fund’s investment objective, BFA uses teams of portfolio managers, investment strategists and other investment specialists. This team approach brings together many disciplines and leverages BFA’s extensive resources.

Pursuant to the Investment Advisory Agreement between BFA and the Trust (entered into on behalf of the Fund), BFA is responsible for substantially all expenses of the Fund, except interest expenses, taxes, brokerage expenses, future distribution fees or expenses and extraordinary expenses.

For its investment advisory services to the Fund, BFA is entitled to receive a management fee from the Fund based on a percentage of the Fund’s average daily net assets, at the annual rate of 0.40%.

BFA is located at 400 Howard Street, San Francisco, CA 94105. It is a wholly owned subsidiary of BTC, which in turn is indirectly wholly-owned by BlackRock, Inc. (“BlackRock”). As of September 30, 2011, BTC and its affiliates, including BFA and BlackRock, provided investment advisory services for assets in excess of $3.35 trillion. BFA, BTC, BlackRock Execution Services, BlackRock and their affiliates deal, trade and invest for their own accounts in the types of securities in which the Fund may also invest.

A discussion regarding the basis for the Trust’s Board of Trustees’ (the “Board”) approval of the Investment Advisory Agreement with BFA is available in the Fund’s annual report for the period ended July 31.

Portfolio Managers. Rene Casis, Diane Hsiung and Greg Savage are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager is responsible for various functions related to portfolio management, including, but not limited to, investing cash inflows, coordinating with members of his or her portfolio management team to focus on certain asset classes, implementing investment strategy, researching and reviewing investment strategy and overseeing members of his or her portfolio management team that have more limited responsibilities.

Rene Casis has been employed by BFA (formerly, Barclays Global Fund Advisors (“BGFA”)) and BTC (formerly, Barclays Global Investors, N.A. (“BGI”)) as a senior portfolio manager since 2009. From 2005 to 2009, Mr. Casis was a trader at Barclays Capital. Prior to that, Mr. Casis was a portfolio manager from 2000 to 2005 for BGFA and BGI. Mr. Casis has been a Portfolio Manager of the Fund since 2010.

Diane Hsiung has been employed by BFA and BTC as a senior portfolio manager since 2007. Prior to that, Ms. Hsiung was a portfolio manager from 2002 to 2006 for BGFA and BGI. Ms. Hsiung has been a Portfolio Manager of the Fund since 2008.

Greg Savage has been employed by BFA and BTC as a senior portfolio manager since 2006. Prior to that, Mr. Savage was a portfolio manager from 2001 to 2006 for BGFA and BGI. Mr. Savage has been a Portfolio Manager of the Fund since 2008.

The Fund’s SAI provides additional information about the Portfolio Managers’ compensation, other accounts managed by the Portfolio Managers and the Portfolio Managers’ ownership (if any) of shares in the Fund.

Administrator, Custodian and Transfer Agent. State Street Bank and Trust Company (“State Street”) is the administrator, custodian and transfer agent for the Fund.

Conflicts of Interest. BFA wants you to know that there are certain entities with which BFA has relationships that may give rise to conflicts of interest, or the appearance of conflicts of interest. These entities include the following: BFA’s affiliates (including BlackRock and The PNC Financial Services Group, Inc., and each of their affiliates, directors, partners, trustees, managing members, officers and employees (collectively, the “Affiliates”)) and BlackRock’s significant shareholder, Barclays Bank PLC and its affiliates, including Barclays PLC (each, an “Entity” and together, the “Entities”).

The activities of BFA, the Affiliates and the Entities in the management of, or their interest in, their own accounts and other accounts they manage, may present conflicts of interest that could disadvantage the Fund and its shareholders. BFA and its Affiliates or the Entities provide investment management services to other funds and discretionary managed accounts that may follow an investment program similar to that of the Fund. BFA, its Affiliates and the Entities are involved worldwide with a broad spectrum of financial services and asset management activities and may engage in the ordinary course of business in activities in which their interests or the interests of their clients may conflict with those of the Fund. BFA, one or more of the Affiliates or the Entities acts, or may act, as an investor, investment banker, research provider, investment manager, financier, underwriter, advisor, market maker, trader, prime broker, lender, agent or principal, and have other direct and indirect interests, in securities, currencies and other instruments in which the Fund may directly or indirectly invest. Thus, it is likely that the Fund will have multiple business relationships with and will invest in, engage in transactions with, make voting decisions with respect to, or obtain services from, entities for which BFA, an Affiliate or an Entity performs or seeks to perform investment banking or other services.

BFA or one or more Affiliates or Entities may engage in proprietary trading and advise accounts and funds that have investment objectives similar to those of the Fund and/

or that engage in and compete for transactions in the same types of securities, currencies and other instruments as the Fund, including in securities issued by other open-end and closed-end investment management companies, including investment companies that are affiliated with the Fund and BFA, to the extent permitted under the Investment Company Act of 1940, as amended (the “1940 Act”). The trading activities of BFA, these Affiliates and Entities are carried out without reference to positions held directly or indirectly by the Fund and may result in BFA, an Affiliate or an Entity having positions that are adverse to those of the Fund.

No Affiliate or Entity is under any obligation to share any investment opportunity, idea or strategy with the Fund. As a result, an Affiliate or an Entity may compete with the Fund for appropriate investment opportunities. As a result of this and several other factors, the results of the Fund’s investment activities may differ from those of an Affiliate or an Entity and of other accounts managed by an Affiliate or an Entity, and it is possible that the Fund could sustain losses during periods in which one or more Affiliates or Entities and other accounts achieve profits on their trading for proprietary or other accounts. The opposite result is also possible.

The Fund may, from time to time, enter into transactions in which BFA or an Affiliate’s or an Entity’s clients have an interest adverse to the Fund. Furthermore, transactions undertaken by Affiliate-advised clients may adversely impact the Fund. Transactions by one or more Affiliate- or Entity-advised clients or BFA may have the effect of diluting or otherwise disadvantaging the values, prices or investment strategies of the Fund.

An Entity may maintain securities indices as part of its product offerings. Index-based funds seek to track the performance of securities indices and may use the name of the index in the fund name. Index providers, including the Entities, may be paid licensing fees for use of their indices or index names. Entities will not be obligated to license their indices to BFA and its Affiliates, and BFA and its Affiliates will not be assured that the terms of any index licensing agreement with the Entities will be as favorable as those terms offered to other index licensees.

The Fund’s activities may be limited because of regulatory restrictions applicable to one or more Affiliates or Entities, and/or their internal policies designed to comply with such restrictions. In addition, the Fund may invest in securities of companies with which an Affiliate or an Entity has or is trying to develop investment banking relationships or in which an Affiliate or an Entity has significant debt or equity investments. The Fund also may invest in securities of companies for which an Affiliate or an Entity provides or may some day provide research coverage. An Affiliate or an Entity may have business relationships with and purchase or distribute or sell services or products from or to distributors, consultants or others who recommend the Fund or who engage in transactions with or for the Fund, and may receive compensation for such services. The Fund may also make brokerage and other payments to Affiliates or Entities in connection with the Fund’s portfolio investment transactions.

Pursuant to a securities lending program approved by the Board, the Fund has retained an Affiliate of BFA to serve as the securities lending agent for the Fund to the extent that the Fund participates in the securities lending program. For these services, the lending agent may receive a fee from the Fund, including a fee based on the returns earned on the Fund’s investment of the cash received as collateral for any loaned

securities. In addition, one or more Affiliates may be among the entities to which the Fund may lend its portfolio securities under the securities lending program.

The activities of BFA, the Affiliates or Entities may give rise to other conflicts of interest that could disadvantage the Fund and its shareholders. BFA has adopted policies and procedures designed to address these potential conflicts of interest. See the Fund’s SAI for further information.

Buying and Selling Shares. Shares of the Fund may be acquired or redeemed directly from the Fund only in Creation Units or multiples thereof, as discussed in the Creations and Redemptions section of this Prospectus. Only an Authorized Participant (as defined in the Creations and Redemptions section) may engage in creation or redemption transactions directly with the Fund. Once created, shares of the Fund generally trade in the secondary market in amounts less than a Creation Unit.

Shares of the Fund are listed on a national securities exchange for trading during the trading day. Shares can be bought and sold throughout the trading day like shares of other publicly-traded companies. The Trust does not impose any minimum investment for shares of the Fund purchased on an exchange. The Fund’s shares trade under the trading symbol “EFV.”

Buying or selling Fund shares on an exchange involves two types of costs that may apply to all securities transactions. When buying or selling shares of the Fund through a broker, you will likely incur a brokerage commission or other charges determined by your broker. The commission is frequently a fixed amount and may be a significant proportional cost for investors seeking to buy or sell small amounts of shares. In addition, you may incur the cost of the “spread” – that is, any difference between the bid price and the ask price. The spread varies over time for shares of the Fund based on its trading volume and market liquidity, and is generally lower if the Fund has a lot of trading volume and market liquidity, and higher if the Fund has little trading volume and market liquidity.

The Board has adopted a policy of not monitoring for frequent purchases and redemptions of Fund shares (“frequent trading”) that appear to attempt to take advantage of a potential arbitrage opportunity presented by a lag between a change in the value of the Fund’s portfolio securities after the close of the primary markets for the Fund’s portfolio securities and the reflection of that change in the Fund’s NAV (“market timing”), because the Fund generally sells and redeems its shares directly through transactions that are in-kind and/or for cash, subject to the conditions described below under Creations and Redemptions. The Board has not adopted a policy of monitoring for other frequent trading activity because shares of the Fund are listed for trading on a national securities exchange.

The national securities exchange on which the Fund’s shares are listed is open for trading Monday through Friday and is closed on weekends and the following holidays:

New Year’s Day, Martin Luther King, Jr. Day, Presidents’ Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day. The Fund’s primary listing exchange is NYSE Arca.

Section 12(d)(1) of the 1940 Act restricts investments by investment companies in the securities of other investment companies. Registered investment companies are permitted to invest in the Fund beyond the limits set forth in Section 12(d)(1), subject to certain terms and conditions set forth in SEC rules or in an SEC exemptive order issued to the Trust. In order for a registered investment company to invest in shares of the Fund beyond the limitations of Section 12(d)(1) pursuant to the exemptive relief obtained by the Trust, the registered investment company must enter into an agreement with the Trust.

Book Entry. Shares of the Fund are held in book-entry form, which means that no stock certificates are issued. The Depository Trust Company (“DTC”) or its nominee is the record owner of all outstanding shares of the Fund and is recognized as the owner of all shares for all purposes.

Investors owning shares of the Fund are beneficial owners as shown on the records of DTC or its participants. DTC serves as the securities depository for shares of the Fund. DTC participants include securities brokers and dealers, banks, trust companies, clearing corporations and other institutions that directly or indirectly maintain a custodial relationship with DTC. As a beneficial owner of shares, you are not entitled to receive physical delivery of stock certificates or to have shares registered in your name, and you are not considered a registered owner of shares. Therefore, to exercise any right as an owner of shares, you must rely upon the procedures of DTC and its participants. These procedures are the same as those that apply to any other securities that you hold in book-entry or “street name” form.

Share Prices. The trading prices of the Fund’s shares in the secondary market generally differ from the Fund’s daily NAV and are affected by market forces such as supply and demand, economic conditions and other factors. Information regarding the intraday value of shares of the Fund, also known as the “indicative optimized portfolio value” (“IOPV”), is disseminated every 15 seconds throughout the trading day by the national securities exchange on which the Fund’s shares are listed or by market data vendors or other information providers. The IOPV is based on the current market value of the securities and/or cash required to be deposited in exchange for a Creation Unit. The IOPV does not necessarily reflect the precise composition of the current portfolio of securities held by the Fund at a particular point in time or the best possible valuation of the current portfolio. Therefore, the IOPV should not be viewed as a “real-time” update of the Fund’s NAV, which is computed only once a day. The IOPV is generally determined by using both current market quotations and/or price quotations obtained from broker-dealers that may trade in the portfolio securities held by the Fund. The quotations of certain Fund holdings may not be updated during U.S. trading hours if such holdings do not trade in the United States. The Fund is not involved in, or responsible for, the calculation or dissemination of the IOPV and makes no representation or warranty as to its accuracy.

Determination of Net Asset Value. The NAV of the Fund normally is determined once daily Monday through Friday, generally as of the regularly scheduled close of

business of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m., Eastern time) on each day that the NYSE is open for trading, based on prices at the time of closing provided that (a) any Fund assets or liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers (as detailed below) and (b) U.S. fixed income assets may be valued as of the announced closing time for trading in fixed income instruments in a particular market or exchange. The NAV of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets held by the Fund, and its liabilities, are determined pursuant to valuation policies and procedures approved by the Board. The Fund’s assets and liabilities are valued primarily on the basis of market quotations.

Equity investments are valued at market value, which is generally determined using the last reported official closing price or last trading price on the exchange or market on which the security is primarily traded at the time of valuation.

The Fund invests in foreign securities. Foreign currency exchange rates are generally determined as of 4:00 p.m., London time. Foreign securities owned by the Fund may trade on weekends or other days when the Fund does not price its shares. As a result, the Fund’s NAV may change on days when Authorized Participants will not be able to purchase or redeem Fund shares.

Generally, trading in foreign securities, U.S. government securities, money market instruments and certain fixed-income securities is substantially completed each day at various times prior to the close of business on the NYSE. The values of such securities used in computing the NAV of the Fund are determined as of such times.

When market quotations are not readily available or are believed by BFA to be unreliable, the Fund’s investments are valued at fair value. Fair value determinations are made by BFA in accordance with policies and procedures approved by the Fund’s Board. BFA may conclude that a market quotation is not readily available or is unreliable if a security or other asset or liability does not have a price source due to its lack of liquidity, if a market quotation differs significantly from recent price quotations or otherwise no longer appears to reflect fair value, where the security or other asset or liability is thinly traded, or where there is a significant event subsequent to the most recent market quotation. A “significant event” is an event that, in the judgment of BFA, is likely to cause a material change to the closing market price of the asset or liability held by the Fund. Foreign securities whose values are affected by volatility that occurs in U.S. markets on a trading day after the close of foreign securities markets may be fair valued.

Fair value represents a good faith approximation of the value of an asset or liability. The fair value of an asset or liability held by the Fund is the amount the Fund might reasonably expect to receive from the current sale of that asset or the cost to extinguish that liability in an arm’s-length transaction. Valuing the Fund’s investments using fair value pricing will result in prices that may differ from current market valuations and that may not be the price at which those investments could have been

sold during the period in which the particular fair values were used. Use of fair value prices and certain current market valuations could result in a difference between the prices used to calculate the Fund’s NAV and the prices used by the Underlying Index, which, in turn, could result in a difference between the Fund’s performance and the performance of the Underlying Index.

The value of assets or liabilities denominated in non-U.S. currencies will be converted into U.S. dollars using exchange rates deemed appropriate by BFA as investment adviser. Use of a rate different from the rate used by the Index Provider may adversely affect the Fund’s ability to track the Underlying Index.

Dividends and Distributions

General Policies. Dividends from net investment income, if any, generally are declared and paid semi-annually by the Fund. Distributions of net realized securities gains, if any, generally are declared and paid once a year, but the Trust may make distributions on a more frequent basis for the Fund. The Trust reserves the right to declare special distributions if, in its reasonable discretion, such action is necessary or advisable to preserve its status as a regulated investment company (“RIC”) or to avoid imposition of income or excise taxes on undistributed income or realized gains.

Dividends and other distributions on shares of the Fund are distributed on a pro rata basis to beneficial owners of such shares. Dividend payments are made through DTC participants and indirect participants to beneficial owners then of record with proceeds received from the Fund.

Dividend Reinvestment Service. No dividend reinvestment service is provided by the Trust. Broker-dealers may make available the DTC book-entry Dividend Reinvestment Service for use by beneficial owners of the Fund for reinvestment of their dividend distributions. Beneficial owners should contact their broker to determine the availability and costs of the service and the details of participation therein. Brokers may require beneficial owners to adhere to specific procedures and timetables. If this service is available and used, dividend distributions of both income and realized gains will be automatically reinvested in additional whole shares of the Fund purchased in the secondary market.

Taxes. As with any investment, you should consider how your investment in shares of the Fund will be taxed. The tax information in this Prospectus is provided as general information, based on current law. You should consult your own tax professional about the tax consequences of an investment in shares of the Fund.

Unless your investment in Fund shares is made through a tax-exempt entity or tax-deferred retirement account, such as an IRA, you need to be aware of the possible tax consequences when the Fund makes distributions or you sell Fund shares.

Taxes on Distributions. Distributions from the Fund’s net investment income (other than qualified dividend income), including distributions of income from securities lending and distributions out of the Fund’s net short-term capital gains, if any, are taxable to you as ordinary income. Distributions by the Fund of net long-term capital gains in excess of net short-term capital losses (capital gain dividends) are taxable to you as long-term capital gains, generally at a 15% tax rate (0% at certain income levels), regardless of how long you have held the Fund’s shares. Distributions by the

Fund that qualify as qualified dividend income are taxable to you at long-term capital gain rates for taxable years beginning on or before December 31, 2012. The 15% and 0% tax rates expire for taxable years beginning after December 31, 2012. Maximum long-term capital gain income tax rates are scheduled to rise to 20% in 2013. Beginning in 2013, a 3.8% U.S. federal Medicare contribution tax will be imposed on “net investment income,” including interest, dividends, and capital gains, of U.S. individuals with income exceeding $200,000 (or $250,000 if married and filing jointly), and of estates and trusts.

Dividends will be qualified dividend income to you if they are attributable to qualified dividend income received by the Fund. Generally, qualified dividend income includes dividend income from taxable U.S. corporations and qualified non-U.S. corporations, provided that the Fund satisfies certain holding period requirements in respect of the stock of such corporations and has not hedged its position in the stock in certain ways. Substitute dividends received by the Fund with respect to dividends paid on securities lent out will not be qualified dividend income. For this purpose, a qualified non-U.S. corporation means any non-U.S. corporation that is eligible for benefits under a comprehensive income tax treaty with the United States, which includes an exchange of information program or if the stock with respect to which the dividend was paid is readily tradable on an established United States securities market. The term excludes a corporation that is a passive foreign investment company.

Dividends received by the Fund from a real estate investment trust (“REIT”) or another RIC generally are qualified dividend income only to the extent the dividend distributions are made out of qualified dividend income received by such REIT or RIC. It is expected that dividends received by the Fund from a REIT and distributed to a shareholder generally will be taxable to the shareholder as ordinary income.

For a dividend to be treated as qualified dividend income, the dividend must be received with respect to a share of stock held without being hedged by the Fund, and with respect to a share of the Fund held without being hedged by you, for 61 days during the 121-day period beginning at the date which is 60 days before the date on which such share becomes ex-dividend with respect to such dividend or, in the case of certain preferred stock, 91 days during the 181-day period beginning 90 days before such date.

If your Fund shares are loaned out pursuant to a securities lending arrangement, you may lose the ability to use foreign tax credits passed through by the Fund or to treat Fund dividends paid while the shares are held by the borrower as qualified dividend income.

In general, your distributions are subject to U.S. federal income tax for the year when they are paid. Certain distributions paid in January, however, may be treated as paid on December 31 of the prior year.

If the Fund’s distributions exceed current and accumulated earnings and profits, all or a portion of the distributions made in the taxable year may be recharacterized as a return of capital to shareholders. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and result in a higher capital gain or lower capital loss when those shares on which the distribution was received are

sold. Once a shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain, if the shareholder holds shares of the Fund as capital assets.

If you are neither a resident nor a citizen of the United States or if you are a non-U.S. entity, the Fund’s ordinary income dividends (which include distributions of net short-term capital gains) will generally be subject to a 30% U.S. withholding tax, unless a lower treaty rate applies, provided that withholding tax will generally not apply to any gain or income realized by a non-U.S. shareholder in respect of any distributions of long-term capital gains or upon the sale or other disposition of shares of the Fund.

A 30% withholding tax will be imposed on dividends paid after December 31, 2013, and redemption proceeds paid after December 31, 2014, to (i) foreign financial institutions including non-U.S. investment funds unless they agree to collect and disclose to the Internal Revenue Service (“IRS”) information regarding their direct and indirect U.S. account holders and (ii) certain other foreign entities, unless they certify certain information regarding their direct and indirect U.S. owners. To avoid withholding, foreign financial institutions will need to enter into agreements with the IRS that state that they will provide the IRS information, including the name, address and taxpayer identification number of direct and indirect U.S. account holders, comply with due diligence procedures with respect to the identification of U.S. accounts, report to the IRS certain information with respect to U.S. accounts maintained, agree to withhold tax on certain payments made to non-compliant foreign financial institutions or to account holders who fail to provide the required information, and determine certain other information as to their account holders. Other foreign entities will need to provide the name, address, and taxpayer identification number of each substantial U.S. owner or certifications of no substantial U.S. ownership unless certain exceptions apply.

Dividends, interest and capital gains earned by the Fund with respect to non-U.S. securities may give rise to withholding and other taxes imposed by non-U.S. countries. Tax conventions between certain countries and the United States may reduce or eliminate such taxes. If more than 50% of the total assets of the Fund at the close of a year consists of non-U.S. stocks or securities, the Fund may “pass through” to you certain non-U.S. income taxes (including withholding taxes) paid by the Fund. This means that you would be considered to have received as an additional dividend your share of such non-U.S. taxes, but you may be entitled to either a corresponding tax deduction in calculating your taxable income, or, subject to certain limitations, a credit in calculating your U.S. federal income tax.

For purposes of foreign tax credits for U.S. shareholders of the Fund, foreign capital gains taxes may not produce associated foreign source income, thereby limiting a U.S. person’s ability to use such credits.

If you are a resident or a citizen of the United States, by law, back-up withholding will apply to your distributions and proceeds if you have not provided a taxpayer identification number or social security number and made other required certifications.

Taxes When Shares are Sold. Currently, any capital gain or loss realized upon a sale of Fund shares is generally treated as a long-term gain or loss if the shares have been held for more than one year. Any capital gain or loss realized upon a sale of Fund

shares held for one year or less is generally treated as short-term gain or loss, except that any capital loss on the sale of shares held for six months or less is treated as long-term capital loss to the extent that capital gain dividends were paid with respect to such shares. Beginning in 2013, any such capital gains, including from sales of Fund shares or from capital gain dividends, will be included in “net investment income” for purposes of the 3.8% U.S. federal Medicare contribution tax mentioned above.

The foregoing discussion summarizes some of the consequences under current U.S. federal tax law of an investment in the Fund. It is not a substitute for personal tax advice. You may also be subject to state and local taxation on Fund distributions and sales of shares. Consult your personal tax adviser about the potential tax consequences of an investment in shares of the Fund under all applicable tax laws.

Creations and Redemptions. Prior to trading in the secondary market, shares of the Fund are “created” at NAV by market makers, large investors and institutions only in block-size Creation Units of 400,000 shares or multiples thereof. Each “creator” or “Authorized Participant” enters into an authorized participant agreement with the Fund’s distributor, SEI Investments Distribution Co. (the “Distributor”). Only an Authorized Participant may create or redeem Creation Units directly with the Fund. A creation transaction, which is subject to acceptance by the transfer agent, generally takes place when an Authorized Participant deposits into the Fund a designated portfolio of securities and a specified amount of cash approximating the holdings of the Fund in exchange for a specified number of Creation Units. To the extent practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund.

Similarly, shares can be redeemed only in Creation Units, generally for a designated portfolio of securities and a specified amount of cash held by the Fund (“Fund Securities”). Except when aggregated in Creation Units, shares are not redeemable by the Fund. The prices at which creations and redemptions occur are based on the next calculation of NAV after an order is received in a form described in the authorized participant agreement.

The Fund intends to comply with the U.S. federal securities laws in accepting securities for deposit and satisfying redemptions with redemption securities by, among other means, assuring that any securities accepted for deposit and any securities used to satisfy redemption requests will be sold in transactions that would be exempt from registration under the Securities Act of 1933, as amended (the “1933 Act”). Further, an Authorized Participant that is not a “qualified institutional buyer,” as such term is defined under Rule 144A of the 1933 Act, will not be able to receive Fund Securities that are restricted securities eligible for resale under Rule 144A.

Creations and redemptions must be made through a firm that is either a member of the Continuous Net Settlement System of the National Securities Clearing Corporation or a DTC participant and has executed an agreement with the Distributor with respect to creations and redemptions of Creation Unit aggregations. Information about the procedures regarding creation and redemption of Creation Units (including the cut-off times for receipt of creation and redemption orders) is included in the Fund’s SAI.

Because new shares may be created and issued on an ongoing basis, at any point during the life of the Fund a “distribution,” as such term is used in the 1933 Act, may be occurring. Broker-dealers and other persons are cautioned that some activities on their part may, depending on the circumstances, result in their being deemed participants in a distribution in a manner that could render them statutory underwriters and subject to the prospectus delivery and liability provisions of the 1933 Act. Any determination of whether one is an underwriter must take into account all the relevant facts and circumstances of each particular case.

Broker-dealers should also note that dealers who are not “underwriters” but are participating in a distribution (as contrasted to ordinary secondary transactions), and thus dealing with shares that are part of an “unsold allotment” within the meaning of Section 4(3)(C) of the 1933 Act, would be unable to take advantage of the prospectus delivery exemption provided by Section 4(3) of the 1933 Act. For delivery of prospectuses to exchange members, the prospectus delivery mechanism of Rule 153 under the 1933 Act is available only with respect to transactions on a national securities exchange.

Costs Associated with Creations and Redemptions. Authorized Participants are charged standard creation and redemption transaction fees to offset transfer and other transaction costs associated with the issuance and redemption of Creation Units. The standard creation and redemption transaction fees are set forth in the table below. The standard creation transaction fee is charged to the Authorized Participant on the day such Authorized Participant creates a Creation Unit, and is the same regardless of the number of Creation Units purchased by the Authorized Participant on the applicable business day. Similarly, the standard redemption transaction fee is charged to the Authorized Participant on the day such Authorized Participant redeems a Creation Unit, and is the same regardless of the number of Creation Units redeemed by the Authorized Participant on the applicable business day. Creations and redemptions for cash (when cash creations and redemptions (in whole or in part) are available or specified) are also subject to an additional charge (up to the maximum amounts shown in the table below). This charge is intended to compensate for brokerage, tax, foreign exchange, execution, market impact and other costs and expenses related to cash transactions. Investors who use the services of a broker or other financial intermediary may pay fees for such services.

The following table shows, as of September 30, 2011, the approximate value of one Creation Unit, standard fees and maximum additional charges for creations and redemptions (as described above):

Householding. Householding is an option available to certain Fund investors. Householding is a method of delivery, based on the preference of the individual investor, in which a single copy of certain shareholder documents can be delivered to investors who share the same address, even if their accounts are registered under different names. Please contact your broker-dealer if you are interested in enrolling in householding and receiving a single copy of prospectuses and other shareholder documents, or if you are currently enrolled in householding and wish to change your householding status.

Distribution

The Distributor distributes Creation Units for the Fund on an agency basis. The Distributor does not maintain a secondary market in shares of the Fund. The Distributor has no role in determining the policies of the Fund or the securities that are purchased or sold by the Fund. The Distributor’s principal address is One Freedom Valley Drive, Oaks, PA 19456.

In addition, BFA or its Affiliates make payments to broker-dealers, banks or other financial intermediaries (together, “intermediaries”) related to marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems, or their making shares of the Fund and certain other iShares funds available to their customers. Such payments, which may be significant to the intermediary, are not made by the Fund. Rather, such payments are made by BFA or its Affiliates from their own resources, which come directly or indirectly in part from fees paid by the iShares funds complex. Payments of this type are sometimes referred to as revenue-sharing payments. A financial intermediary may make decisions about which investment options it recommends or makes available, or the level of services provided, to its customers based on the revenue-sharing payments it is eligible to receive. Therefore, such payments to an intermediary create conflicts of interest between the intermediary and its customers and may cause the intermediary to recommend the Fund or other iShares funds over another investment. More information regarding these payments is contained in the Fund’s SAI. Please contact your salesperson or other investment professional for more information regarding any such payments his or her firm may receive from BFA or its Affiliates.

Financial Highlights

The financial highlights table is intended to help investors understand the Fund’s financial performance for the past five years. Certain information reflects financial results for a single share of the Fund. The total returns in the table represent the rate that an investor would have earned (or lost) on an investment in the Fund, assuming reinvestment of all dividends and distributions. This information has been audited by PricewaterhouseCoopers LLP, whose report is included, along with the Fund’s financial statements, in the Fund’s Annual Report (available upon request).

Supplemental Information

I. Premium/Discount Information

The table that follows presents information about the differences between the daily market price on secondary markets for shares of the Fund and the Fund’s NAV. NAV is the price at which the Fund issues and redeems shares. It is calculated in accordance with the standard formula for valuing mutual fund shares. The price used to calculate market returns (“Market Price”) of the Fund generally is determined using the midpoint between the highest bid and the lowest offer on the primary securities exchange on which shares of the Fund are listed for trading, as of the time that the Fund’s NAV is calculated. The Fund’s Market Price may be at, above or below its NAV. The NAV of the Fund will fluctuate with changes in the value of its portfolio holdings. The Market Price of the Fund will fluctuate in accordance with changes in its NAV, as well as market supply and demand.

Premiums or discounts are the differences (expressed as a percentage) between the NAV and Market Price of the Fund on a given day, generally at the time the NAV is calculated. A premium is the amount that the Fund is trading above the reported NAV, expressed as a percentage of the NAV. A discount is the amount that the Fund is trading below the reported NAV, expressed as a percentage of the NAV.

The following information shows the frequency of distributions of premiums and discounts for the Fund for each full calendar quarter of 2010 through September 30, 2011.

Each line in the table shows the number of trading days in which the Fund traded within the premium/discount range indicated. The number of trading days in each premium/discount range is also shown as a percentage of the total number of trading days in the period covered by the table. All data presented here represents past performance, which cannot be used to predict future results.

II. Total Return Information

The tables that follow present information about the total returns of the Fund and the Underlying Index as of the fiscal year ended July 31, 2011.

“Average Annual Total Returns” represent the average annual change in value of an investment over the periods indicated. “Cumulative Total Returns” represent the total change in value of an investment over the period indicated.

The Fund’s NAV is the value of one share of the Fund as calculated in accordance with the standard formula for valuing mutual fund shares. The NAV return is based on the NAV of the Fund and the market return is based on the Market Price of the Fund. Market Price is determined by using the midpoint between the highest bid and the lowest offer on the primary stock exchange on which shares of the Fund are listed for trading, as of the time that the Fund’s NAV is calculated. Since shares of the Fund did not trade in the secondary market until after the Fund’s inception, for the period from inception to the first day of secondary market trading in shares of the Fund, the NAV of the Fund is used as a proxy for the Market Price to calculate market returns. Market and NAV returns assume that dividends and capital gain distributions have been reinvested in the Fund at Market Price and NAV, respectively.

An index is a statistical composite that tracks a specified financial market or sector. Unlike the Fund, the Underlying Index does not actually hold a portfolio of securities and therefore does not incur the expenses incurred by the Fund. These expenses negatively impact the performance of the Fund. Also, market returns do not include brokerage commissions that may be payable on secondary market transactions. If brokerage commissions were included, market returns would be lower. The returns shown in the following tables do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption or sale of Fund shares. The investment return and principal value of shares of the Fund will vary with changes in market conditions. Shares of the Fund may be worth more or less than their original cost when they are redeemed or sold in the market. The Fund’s past performance is no guarantee of future results.

Fund Overview

iSHARES® MSCI EMERGING MARKETS FINANCIALS SECTOR INDEX FUND

Ticker: EMFN Stock Exchange: NASDAQ

Investment Objective

The iShares MSCI Emerging Markets Financials Sector Index Fund (the “Fund”) seeks investment results that correspond generally to the price and yield performance, before fees and expenses, of the MSCI Emerging Markets Financials Index (the “Underlying Index”).

Fees and Expenses

The following table describes the fees and expenses that you will incur if you own shares of the Fund. The investment advisory agreement between iShares Trust (the “Trust”) and BlackRock Fund Advisors (“BFA”) (the “Investment Advisory Agreement”) provides that BFA will pay all operating expenses of the Fund, except interest expenses, taxes, brokerage expenses, future distribution fees or expenses, and extraordinary expenses.

You may also incur usual and customary brokerage commissions when buying or selling shares of the Fund, which are not reflected in the example that follows:

Example. This Example is intended to help you compare the cost of owning shares of the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

Portfolio Turnover. The Fund may pay transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 6% of the average value of its portfolio.

Principal Investment Strategies

The Underlying Index is a free float-adjusted market capitalization-weighted index designed to measure the combined equity market performance of the financial sector of emerging markets countries. Component securities include those of banks, diversified financial companies, insurance companies and real estate companies. As of September 30, 2011, the Underlying Index consisted of companies in the following countries: Brazil, Chile, China, Colombia, the Czech Republic, Egypt, Hungary, India, Indonesia, Mexico, Peru, the Philippines, Poland, Russia, South Africa, South Korea, Thailand and Turkey (together, the “emerging markets financial sector countries”). As of September 30, 2011, the Underlying Index was comprised of 189 securities.

BFA uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to “beat” the index it tracks and does not seek temporary defensive positions when markets decline or appear overvalued.

Indexing may eliminate the chance that the Fund will substantially outperform the Underlying Index but also may reduce some of the risks of active management, such as poor security selection. Indexing seeks to achieve lower costs and better after-tax performance by keeping portfolio turnover low in comparison to actively managed investment companies.

BFA uses a representative sampling indexing strategy to manage the Fund. “Representative sampling” is an indexing strategy that involves investing in a representative sample of securities that collectively has an investment profile similar to the Underlying Index. The securities selected are expected to have, in the aggregate, investment characteristics (based on factors such as market capitalization and industry weightings), fundamental characteristics (such as return variability and yield) and liquidity measures similar to those of the Underlying Index. The Fund may or may not hold all of the securities in the Underlying Index.

The Fund generally invests at least 90% of its assets in securities of the Underlying Index and in depositary receipts representing securities of the Underlying Index. The Fund may invest the remainder of its assets in securities not included in the Underlying Index, but which BFA believes will help the Fund track the Underlying Index and in other investments including futures contracts, options on futures contracts, options and swaps as well as cash and cash equivalents, including shares of money market funds advised by BFA or its affiliates.



S-2   


Table Of Contents



The Fund may lend securities representing up to one-third of the value of the Fund’s total assets (including the value of the collateral received).

The Underlying Index is sponsored by an organization (the “Index Provider”) that is independent of the Fund and BFA. The Index Provider determines the composition and relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index. The Fund’s Index Provider is MSCI Inc. (“MSCI”).

Industry Concentration Policy. The Fund will concentrate its investments (i.e., hold 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. For purposes of this limitation, securities of the U.S. government (including its agencies and instrumentalities) and repurchase agreements collateralized by U.S. government securities are not considered to be issued by members of any industry.

Summary of Principal Risks

As with any investment, you could lose all or part of your investment in the Fund, and the Fund’s performance could trail that of other investments. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund’s net asset value per share (“NAV”), trading price, yield, total return and ability to meet its investment objective.

Asset Class Risk. Securities in the Underlying Index or in the Fund’s portfolio may underperform in comparison to the general securities markets or other asset classes.

Concentration Risk. To the extent that the Fund’s investments are concentrated in a particular issuer, region, country, market, industry or asset class, the Fund may be susceptible to loss due to adverse occurrences affecting that issuer, region, country, market, industry or asset class.

Currency Risk. Because the Fund’s NAV is determined in U.S. dollars, the Fund’s NAV could decline if the currency of a non-U.S. market in which the Fund invests depreciates against the U.S. dollar.

Custody Risk. Less developed markets are more likely to experience problems with the clearing and settling of trades and the holding of securities by local banks, agents and depositories.

Emerging Markets Risk. The Fund’s investments in emerging markets may be subject to a greater risk of loss than investments in more developed markets. Emerging markets may be more likely to experience inflation risk, political turmoil and rapid changes in economic conditions than more developed markets. Emerging markets often have less uniformity in accounting and reporting requirements, unreliable securities valuation and greater risk associated with custody of securities.

Equity Securities Risk. Equity securities are subject to changes in value and their values may be more volatile than other asset classes.

Financial Sector Risk. Performance of companies in the financial sector may be adversely impacted by many factors, including, among others, government regulations, economic conditions, credit

S-3   


Table Of Contents



rating downgrades, changes in interest rates, and decreased liquidity in credit markets. This sector has experienced significant losses in the recent past, and the impact of more stringent capital requirements and of recent or future regulation on any individual financial company or on the sector as a whole cannot be predicted.

Geographic Risk. A natural or other disaster could occur in a geographic region in which the Fund invests, which could affect the economy or particular business operations of companies in the specific geographic region, causing an adverse impact on the Fund’s investments in the affected region.

Insurance Industry Risk. The insurance industry may be significantly affected by changes in interest rates, catastrophic events, price and marketing competition, the imposition of premium rate caps, or other changes in government regulation or tax law, among other factors.

Issuer Risk. Fund performance depends on the performance of individual securities to which the Fund has exposure. Changes to the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA’s investment management strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares, losses from trading in secondary markets, periods of high volatility and disruption in the creation/redemption process of the Fund. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV.

Mid-Capitalization Companies Risk. The Fund may invest in the securities of mid-capitalization companies. Compared to large-capitalization companies, mid-capitalization companies may be less stable and more susceptible to adverse developments and their securities may be more volatile and less liquid.

Non-Diversification Risk. The Fund may invest a large percentage of its assets in securities issued by or representing a small number of issuers. As a result, the Fund’s performance may depend on the performance of a small number of issuers.

Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers are subject to the risks associated with investing in those non-U.S. markets, such as heightened risks of inflation or nationalization. The Fund may lose money due to political, economic and geographic events affecting a non-U.S. issuer or market.

Passive Investment Risk. The Fund is not actively managed and BFA does not attempt to take defensive positions under any market conditions, including declining markets.

Privatization Risk. Some countries in which the Fund invests have begun a process of privatizing certain entities and industries. Privatized entities may lose money or be re-nationalized.

Reliance on Trading Partners Risk. The Fund invests in countries whose economies are heavily dependent upon trading with key partners. Any reduction in this trading may have an adverse impact on the Fund’s investments. Through its trading partners, the Fund is particularly exposed to U.S. Trading Partner Risk.

Risk of Investing in China. China may be subject to considerable degrees of economic, political and social instability.

Securities Lending Risk. The Fund may engage in securities lending. Securities lending involves the risk that the Fund may lose money because the borrower of the Fund’s loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Security Risk. Some countries and regions in which the Fund invests have experienced security concerns. Incidents involving a country’s or region’s security may cause uncertainty in these markets and may adversely affect their economies and the Fund’s investments.

Small-Capitalization Companies Risk. The Fund may invest in the securities of small-capitalization companies. Compared to mid- and large-capitalization companies, small-capitalization companies may be less stable and more susceptible to adverse developments and their securities may be more volatile and less liquid.

Structural Risk. The countries in which the Fund invests may be subject to considerable degrees of economic, political and social instability.

Tracking Error Risk. The performance of the Fund may diverge from that of the Underlying Index. Because the Fund employs a representative sampling strategy, the Fund may experience tracking error to a greater extent than a fund that seeks to replicate an index. BFA EXPECTS THAT THE FUND MAY EXPERIENCE HIGHER TRACKING ERROR THAN IS TYPICAL FOR SIMILAR INDEX EXCHANGE-TRADED FUNDS.

Valuation Risk. The value of the securities in the Fund’s portfolio may change on days when shareholders will not be able to purchase or sell the Fund’s shares.

Performance Information

As of the date of the Fund’s prospectus (the “Prospectus”), the Fund has been in operation for less than one full calendar year and therefore does not report its performance information.

Management

Investment Adviser. BlackRock Fund Advisors.

Portfolio Managers. Christopher Bliss, Rene Casis, Diane Hsiung and Greg Savage (the “Portfolio Managers”) are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager supervises a portfolio management team. Mr. Bliss has been a Portfolio Manager of the Fund since 2011. Mr. Casis has been a Portfolio Manager of the Fund since 2010. Ms. Hsiung and Mr. Savage have been Portfolio Managers of the Fund since inception.

Purchase and Sale of Fund Shares

The Fund is an exchange-traded fund (commonly referred to as an “ETF”). Individual Fund shares may only be purchased and sold on a national securities exchange through a broker-dealer. The price of Fund shares is based on market price, and because ETF shares trade at market prices rather than NAV, shares may trade at a price greater than NAV (a premium) or less than NAV (a discount). The Fund will only issue or redeem shares that have been aggregated into blocks of 50,000 shares or multiples thereof (“Creation Units”) to authorized participants who have entered into agreements with the Fund’s distributor. The Fund generally will issue or redeem Creation Units in return for a designated portfolio of securities (and an amount of cash) that the Fund specifies each day.

Tax Information

The Fund intends to make distributions that may be taxable to you as ordinary income or capital gains, unless you are investing through a tax-deferred arrangement such as a 401(k) plan or an individual retirement account (“IRA”).

Payments to Broker-Dealers and other Financial Intermediaries

If you purchase shares of the Fund through a broker-dealer or other financial intermediary (such as a bank), BFA or other related companies may pay the intermediary for marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems or other services related to the sale or promotion of the Fund. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.

More Information About the Fund

This Prospectus contains important information about investing in the Fund. Please read this Prospectus carefully before you make any investment decisions. Additional information regarding the Fund is available at www.iShares.com.

BFA is the investment adviser to the Fund. Shares of the Fund are listed for trading on The NASDAQ Stock Market (“NASDAQ”). The market price for a share of the Fund may be different from the Fund’s most recent NAV.

ETFs are funds that trade like other publicly-traded securities. The Fund is designed to track an index. Similar to shares of an index mutual fund, each share of the Fund represents a partial ownership in an underlying portfolio of securities intended to track a market index. Unlike shares of a mutual fund, which can be bought and redeemed from the issuing fund by all shareholders at a price based on NAV, shares of the Fund may be purchased or redeemed directly from the Fund at NAV solely by authorized participants. Also unlike shares of a mutual fund, shares of the Fund are listed on a national securities exchange and trade in the secondary market at market prices that change throughout the day.

The Fund invests in a particular segment of the securities markets and seeks to track the performance of a securities index that generally is not representative of the market as a whole. The Fund is designed to be used as part of broader asset allocation strategies. Accordingly, an investment in the Fund should not constitute a complete investment program.

An index is a theoretical financial calculation while the Fund is an actual investment portfolio. The performance of the Fund and the Underlying Index may vary due to transaction costs, non-U.S. currency valuations, asset valuations, corporate actions (such as mergers and spin-offs), timing variances and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions (such as diversification requirements) that apply to the Fund but not to the Underlying Index or to the use of representative sampling. “Tracking error” is the difference between the performance (return) of the Fund’s portfolio and that of the Underlying Index. BFA expects that, over time, the Fund’s tracking error will not exceed 5%. Because the Fund uses a representative sampling indexing strategy, it can be expected to have a larger tracking error than if it used a replication indexing strategy. “Replication” is an indexing strategy in which a fund invests in substantially all of the securities in its underlying index in approximately the same proportions as in the underlying index.

An investment in the Fund is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, BFA or any of its affiliates.

The Fund’s investment objective and the Underlying Index may be changed without shareholder approval.

A Further Discussion of Principal Risks

The Fund is subject to various risks, including the principal risks noted below, any of which may adversely affect the Fund’s NAV, trading price, yield, total return and ability to meet its investment objective. You could lose all or part of your investment in the Fund, and the Fund could underperform other investments.

Asian Structural Risk. Certain Asian countries are subject to a considerable degree of economic, political and social instability, which could adversely affect the Fund’s investments:

  • Asian Economic Risk. Certain Asian economies have experienced over-extension of credit, currency devaluations and restrictions, high unemployment, high inflation, decreased exports and economic recessions. Economic events in any one Asian country can have a significant effect on the entire Asian region as well as on major trading partners outside Asia, and any adverse effect on some or all of the Asian countries and regions in which the Fund invests. The securities markets in some Asian economies are relatively underdeveloped and may subject the Fund to higher transaction costs or greater uncertainty than investments in more developed securities markets. Such risks may adversely affect the value of the Fund’s investments.
  • Government Control and Regulations. Governments of many Asian countries have implemented significant economic reforms in order to liberalize trade policy, promote foreign investment in their economies, reduce government control of the economy and develop market mechanisms. There can be no assurance these reforms will continue or that they will be effective. Despite recent reform and privatizations, significant regulation of investment and industry is still pervasive in many Asian countries and may restrict foreign ownership of domestic corporations and repatriation of assets, which may adversely affect Fund investments.
  • Political and Social Risk. Governments in some Asian countries are authoritarian in nature, have been installed or removed as a result of military coups or have periodically used force to suppress civil dissent. Disparities of wealth, the pace and success of democratization and ethnic, religious and racial disaffection have led to social turmoil, violence and labor unrest in some countries. Unanticipated or sudden political or social developments may result in sudden and significant investment losses.
  • Expropriation Risk. Investing in certain Asian countries involves risk of loss due to expropriation, nationalization, or confiscation of assets and property or the imposition of restrictions on foreign investments and on repatriation of capital invested.

Asset Class Risk. The securities in the Underlying Index or in the Fund’s portfolio may underperform the returns of other securities or indexes that track other countries, groups of countries, regions, industries, groups of industries, markets, asset classes or sectors. Various types of securities or indexes tend to experience cycles of outperformance and underperformance in comparison to the general securities markets.

Concentration Risk. To the extent that the Fund’s portfolio reflects the Underlying Index’s concentration in the securities of a particular issuer or issuers in a particular country, group of countries, region, market, industry, group of industries, sector or asset class, the Fund may be adversely affected by the performance of those securities, may be subject to increased price volatility and may be more susceptible to adverse economic, market, political or regulatory occurrences affecting that issuer, country, group of countries, region, market, industry, group of industries, sector or asset class.

Currency Risk. Because the Fund’s NAV is determined on the basis of the U.S. dollar, investors may lose money if the currency of a non-U.S. market in which the Fund invests depreciates against the U.S. dollar, even if the local currency value of the Fund’s holdings in that market increases.

Custody Risk. Custody risk refers to the risks inherent in the process of clearing and settling trades and the holding of securities by local banks, agents and depositories. Low trading volumes and volatile prices in less developed markets may make trades harder to complete and settle, and governments or trade groups may compel local agents to hold securities in designated depositories that are not subject to independent evaluation. Local agents are held only to the standards of care of their local markets. In general, the less developed a country’s securities market is, the greater the likelihood of custody problems.

Emerging Markets Risk. Investments in emerging markets are subject to a greater risk of loss than investments in more developed markets. This is due to, among other things, the potential for greater market volatility, lower trading volume, inflation, political and economic instability, greater risk of a market shutdown and more governmental limitations on foreign investments than typically found in more developed markets. In addition, emerging markets often have less uniformity in accounting and reporting requirements, unreliable securities valuation and greater risks associated with custody of securities.

Equity Securities Risk. The Fund invests in equity securities, which are subject to changes in value that may be attributable to market perception of a particular issuer or to general stock market fluctuations that affect all issuers. Investments in equity securities may be more volatile than investments in other asset classes.

Financial Sector Risk. Companies in the financial sector of an economy are often subject to governmental regulation and, recently, government intervention and the potential for additional regulation, which may adversely affect the scope of their activities, the prices they can charge and the amount of capital they must maintain. Governmental regulation may change frequently and may have significant adverse consequences for companies in the financial sector, including effects not intended by such regulation. The impact of recent or future regulation in various countries on any individual financial company or on the sector as a whole cannot be predicted. Certain risks may impact the value of investments in the financial sector more severely than investments outside this sector, including the risks associated with companies that operate with substantial financial leverage. Companies in the financial sector may also be adversely affected by increases in interest rates and loan losses, decreases in the availability of money or asset valuations, credit rating downgrades and adverse

conditions in other related markets. Over the past few years, the deterioration of the credit markets has impacted a broad range of mortgage, asset-backed, auction rate, sovereign debt and other markets, including U.S. and non-U.S. credit and interbank money markets, thereby affecting a wide range of financial institutions and markets. This situation has created instability in the financial markets and caused certain financial companies to incur large losses. Some financial companies have experienced declines in the valuations of their assets, taken actions to raise capital (such as the issuance of debt or equity securities), or even ceased operations. Some financial companies have borrowed significant amounts of capital from governments and may face future government-imposed restrictions on their businesses or increased government intervention. These actions have caused the securities of many financial companies to decline in value. Insurance companies, in particular, may be subject to severe price competition, which may have an adverse impact on their profitability.

Geographic Risk. Some markets in which the Fund invests are located in parts of the world that have historically been prone to natural disasters, such as earthquakes, volcanoes, droughts, floods, hurricanes and tsunamis, and are economically sensitive to environmental events. Any natural or other disaster could have a significant adverse impact on the economies of these geographic areas, causing an adverse impact on the Fund’s investments in the affected region.

Insurance Industry Risk. The insurance industry is subject to extensive government regulation in some countries and can be significantly affected by changes in interest rates, general economic conditions, price and marketing competition, the imposition of premium rate caps, or other changes in government regulation or tax law. Different segments of the insurance industry can be significantly affected by mortality and morbidity rates, environmental clean-up costs and catastrophic events such as earthquakes, hurricanes and terrorist acts.

Issuer Risk. The performance of the Fund depends on the performance of individual securities to which the Fund has exposure. Any issuer of these securities may perform poorly, causing the value of its securities to decline. Poor performance may be caused by poor management decisions, competitive pressures, changes in technology, expiration of patent protection, disruptions in supply, labor problems or shortages, corporate restructurings, fraudulent disclosures or other factors. Issuers may, in times of distress or at their own discretion, decide to reduce or eliminate dividends, which may also cause their stock prices to decline.

Management Risk. The Fund may not fully replicate the Underlying Index and may hold securities not included in the Underlying Index. As a result, the Fund is subject to the risk that BFA’s investment management strategy, the implementation of which is subject to a number of constraints, may not produce the intended results.

Market Risk. The Fund could lose money due to short-term market movements and over longer periods during market downturns. Securities may decline in value due to factors affecting securities markets generally or particular industries represented in the markets. The value of a security may decline due to general market conditions, economic trends or events that are not specifically related to the issuer of the security or to factors that affect a particular industry or industries. During a general downturn in the securities markets, multiple asset classes may be negatively affected.

Market Trading Risk

Absence of Active Market. Although shares of the Fund are listed for trading on one or more stock exchanges, there can be no assurance that an active trading market for such shares will develop or be maintained.

Risk of Secondary Listings. The Fund’s shares may be listed or traded on U.S. and non-U.S. stock exchanges other than the U.S. stock exchange where the Fund’s primary listing is maintained. There can be no assurance that the Fund’s shares will continue to trade on any such stock exchange or in any market or that the Fund’s shares will continue to meet the requirements for listing or trading on any exchange or in any market. The Fund’s shares may be less actively traded in certain markets than others, and investors are subject to the execution and settlement risks and market standards of the market where they or their broker direct their trades for execution. Certain information available to investors who trade Fund shares on a U.S. stock exchange during regular U.S. market hours may not be available to investors who trade in other markets, which may result in secondary market prices in such markets being less efficient.

Secondary Market Trading Risk. Shares of the Fund may trade in the secondary market at times when the Fund does not accept orders to purchase or redeem shares. At such times, shares may trade in the secondary market with more significant premiums or discounts than might be experienced at times when the Fund accepts purchase and redemption orders.

Secondary market trading in Fund shares may be halted by a stock exchange because of market conditions or other reasons. In addition, trading in Fund shares on a stock exchange or in any market may be subject to trading halts caused by extraordinary market volatility pursuant to “circuit breaker” rules on the stock exchange or market. There can be no assurance that the requirements necessary to maintain the listing or trading of Fund shares will continue to be met or will remain unchanged.

Shares of the Fund May Trade at Prices Other Than NAV. Shares of the Fund trade on stock exchanges at prices at, above or below their most recent NAV. The NAV of the Fund is calculated at the end of each business day and fluctuates with changes in the market value of the Fund’s holdings since the most recent calculation. The trading prices of the Fund’s shares fluctuate continuously throughout trading hours based on market supply and demand rather than NAV. The trading prices of the Fund’s shares may deviate significantly from NAV during periods of market volatility. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV. However, because shares can be created and redeemed in Creation Units at NAV (unlike shares of many closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their NAVs), BFA believes that large discounts or premiums to the NAV of the Fund are not likely to be sustained over the long-term. While the creation/redemption feature is designed to make it likely that the Fund’s shares normally will trade on stock exchanges at prices close to the Fund’s next calculated NAV, exchange prices are not expected to correlate exactly with the Fund’s NAV due to timing reasons as well as market supply and demand factors. In addition, disruptions to creations and

redemptions or extreme market volatility may result in trading prices for shares of the Fund that differ significantly from its NAV.

Costs of Buying or Selling Fund Shares. Buying or selling Fund shares on an exchange involves two types of costs that apply to all securities transactions. When buying or selling shares of the Fund through a broker, you will likely incur a brokerage commission or other charges imposed by brokers as determined by that broker. In addition, you may incur the cost of the “spread” – that is, the difference between what investors are willing to pay for Fund shares (the “bid” price) and the price at which they are willing to sell Fund shares (the “ask” price). Because of the costs inherent in buying or selling Fund shares, frequent trading may detract significantly from investment results and an investment in Fund shares may not be advisable for investors who anticipate regularly making small investments.

Mid-Capitalization Companies Risk. Many of the companies in which the Fund invests are considered mid-capitalization companies. Stock prices of mid-capitalization companies may be more volatile than those of large-capitalization companies and, therefore, the Fund’s share price may be more volatile than those of funds that invest a larger percentage of their assets in stocks issued by large-capitalization companies. Stock prices of mid-capitalization companies are also more vulnerable than those of large-capitalization companies to adverse business or economic developments, and the stocks of mid-capitalization companies may be less liquid, making it difficult for the Fund to buy and sell them. In addition, mid-capitalization companies generally have less diverse product lines than large-capitalization companies and are more susceptible to adverse developments related to their products.

Non-Diversification Risk. The Fund is classified as “non-diversified.” This means that the Fund may invest a large percentage of its assets in securities issued by or representing a small number of issuers. As a result, the Fund may be more susceptible to the risks associated with these particular issuers, or to a single economic, political or regulatory occurrence affecting these issuers.

Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers are subject to all of the risks of investing in the markets where such issuers are located, including heightened risks of inflation or nationalization and market fluctuations caused by economic and political developments. As a result of investing in non-U.S. securities, the Fund may be subject to increased risk of loss caused by any of the factors listed below:

  • Lower levels of liquidity and market efficiency;
  • Greater securities price volatility;
  • Exchange rate fluctuations and exchange controls;
  • Less availability of public information about issuers;
  • Limitations on foreign ownership of securities;
  • Imposition of withholding or other taxes;
  • Imposition of restrictions on the expatriation of the funds or other assets of the Fund;
  • Higher transaction and custody costs and delays in settlement procedures;
  • Difficulties in enforcing contractual obligations;
  • Lower levels of regulation of the securities market;
  • Weaker accounting, disclosure and reporting requirements; and
  • Legal principles related to corporate governance, directors’ fiduciary duties and liabilities and stockholders’ rights in markets in which the Fund invests may differ and/or may not be as extensive or protective as those that apply in the United States.

Passive Investment Risk. The Fund is not actively managed and may be affected by a general decline in market segments related to the Underlying Index. The Fund invests in securities included in, or representative of, the Underlying Index regardless of their investment merits. BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

Privatization Risk. Some countries in which the Fund invests have begun a process of privatizing certain entities and industries. In some instances, investors in newly privatized entities have suffered losses due to the inability of the newly privatized entities to adjust quickly to a competitive environment or changing regulatory and legal standards or, in some cases, due to re-nationalization of such privatized entities. There is no assurance that such losses will not recur.

Reliance on Trading Partners Risk. The economies of many emerging markets countries are dependent on each other and on the United States as key trading partners. Reduction in spending on the products and services of these countries by any of their key trading partners, institution of tariffs or other trade barriers or a slowdown in the economies of any of their key trading partners may cause an adverse impact on the economies of the emerging markets countries in which the Fund invests.


U.S. Trading Partners Risk. The United States is a significant, and in some cases the most significant, trading partner of or foreign investor in the financial sectors of certain emerging markets countries and the economies of these countries may be particularly affected by changes in the U.S. economy. Decreasing U.S. imports, new trade regulations, changes in the U.S. dollar exchange rate or a recession in the United States may have a material adverse effect on the economies of these countries.

Risk of Investing in China. The Chinese economy is subject to a considerable degree of economic, political and social instability:

Political and Social Risk. The Chinese government is authoritarian and has periodically used force to suppress civil dissent. Disparities of wealth and the pace of economic liberalization may lead to social turmoil, violence and labor unrest. In addition, China continues to experience disagreements related to integration with Hong Kong and religious and nationalist disputes in Tibet and Xinjiang. There is also a greater risk involved in currency fluctuations, currency convertibility, interest rate fluctuations and higher rates of inflation as a result of internal social unrest or conflicts with other countries. Unanticipated political or social developments may result in sudden and significant investment losses. China’s growing income inequality and worsening environmental conditions also are factors that may affect the Chinese economy.

Government Control and Regulations. The Chinese government has implemented significant economic reforms in order to liberalize trade policy, promote foreign investment in the economy, reduce government control of the economy and develop market mechanisms. There can be no assurance these reforms will continue or that they will be effective. Despite recent reform and privatizations, significant regulation of investment and industry is still pervasive and the Chinese government may restrict foreign ownership of Chinese corporations and repatriation of assets. Chinese markets generally continue to experience inefficiency, volatility and pricing anomalies that may be connected to governmental influence, a lack of publicly-available information and/or political and social instability.

Economic Risk. The Chinese economy has grown rapidly during the past several years and there is no assurance that this growth rate will be maintained. China may experience substantial rates of inflation or economic recessions, causing a negative effect on the economy and securities market. Delays in enterprise restructuring, slow development of well-functioning financial markets and widespread corruption have also hindered performance of the Chinese economy. China continues to receive substantial pressure from trading partners to liberalize official currency exchange rates.

Expropriation Risk. The Chinese government maintains a major role in economic policymaking and investing in China involves risk of loss due to expropriation, nationalization, or confiscation of assets and property or the imposition of restrictions on foreign investments and on repatriation of capital invested.

Securities Lending Risk. The Fund may engage in securities lending. Securities lending involves the risk that the Fund may lose money because the borrower of the Fund’s loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for the loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Security Risk. Some geographic areas in which the Fund invests have experienced acts of terrorism or strained international relations due to territorial disputes, historical animosities or other defense concerns. These situations may cause uncertainty in the markets of these geographic areas and may adversely affect the performance of their economies.

Small-Capitalization Companies Risk. Many of the companies in which the Fund invests are considered small-capitalization companies. Stock prices of small-capitalization companies may be more volatile than those of larger companies and, therefore, the Fund’s share price may be more volatile than those of funds that invest a larger percentage of their assets in stocks issued by mid- or large-capitalization companies. Stock prices of small-capitalization companies are generally more vulnerable than those of mid- or large-capitalization companies to adverse business and economic developments. Securities of small-capitalization companies may be thinly traded, making it difficult for the Fund to buy and sell them. In addition, small-capitalization companies are typically less financially stable than larger, more established companies and may depend on a small number of essential personnel,

making them more vulnerable to loss of personnel. Small-capitalization companies also normally have less diverse product lines than mid- or large-capitalization companies and are more susceptible to adverse developments concerning their products.

Structural Risk. Certain political, economic, legal and currency risks have contributed to a high degree of price volatility in the equity markets of emerging markets countries and could adversely affect investments in the Fund:


Political and Social Risk. Disparities of wealth, the pace and success of democratization and ethnic, religious and racial disaffection, among other factors, have led to social unrest, violence and labor unrest in some emerging markets countries. Unanticipated or sudden political or social developments may result in sudden and significant investment losses.


Economic Risk. Some emerging markets countries may experience economic instability, including instability resulting from substantial rates of inflation or significant devaluations of their currency, or economic recessions causing a negative effect on the economies and securities markets of their economies. Some of these countries may also impose restrictions on the exchange or export of currency or adverse currency exchange rates and may be characterized by a lack of available currency hedging instruments.


Expropriation and/or Nationalization Risk. Investments in certain emerging markets countries may be subject to loss due to expropriation or nationalization of assets and property or the imposition of restrictions on foreign investments and repatriation of capital.


Large Government Debt Risk. Chronic structural public sector deficits in some emerging markets countries may adversely impact investments in the Fund.

Tracking Error Risk. Imperfect correlation between the Fund’s portfolio securities and those in the Underlying Index, rounding of prices, changes to the Underlying Index and regulatory requirements may cause tracking error, which is the divergence of the Fund’s performance from that of the Underlying Index. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Underlying Index does not. Because the Fund employs a representative sampling strategy, the Fund may experience tracking error to a greater extent than a fund that seeks to replicate an index. BFA EXPECTS THAT THE FUND MAY EXPERIENCE HIGHER TRACKING ERROR THAN IS TYPICAL FOR SIMILAR INDEX ETFS.

Valuation Risk. Because non-U.S. exchanges may be open on days when the Fund does not price its shares, the value of the securities in the Fund’s portfolio may change on days when shareholders will not be able to purchase or sell the Fund’s shares. In addition, for purposes of calculating the Fund’s NAV, the value of assets denominated in non-U.S. currencies is converted into U.S. dollars using exchange rates deemed appropriate by BFA. This conversion may result in a difference between the prices used to calculate the Fund’s NAV and the prices used by the Underlying Index, which, in turn, could result in a difference between the Fund’s performance and the performance of the Underlying Index.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

Central and South American Economic Risk. The economies and financial sectors of certain emerging markets countries are affected by the economies of Central and South American countries, some of which have experienced high interest rates, economic volatility, inflation, currency devaluations, government defaults and high unemployment rates. In addition, commodities (such as oil, gas and minerals) represent a significant percentage of the region’s exports and many economies in this region are particularly sensitive to fluctuations in commodity prices. Adverse economic events in one country may have a significant adverse effect on other countries in this region and on the financial sectors of emerging markets countries.

Eastern European Economic Risk. The Economic and Monetary Union of the European Union (the “EU”) requires compliance with restrictions on inflation rates, deficits, interest rates, debt levels and fiscal and monetary controls, each of which may significantly affect every country in Europe, even for countries that do not participate in the EU. Decreasing imports or exports, changes in governmental or EU regulations on trade, changes in the exchange rate of the euro, the default or threat of default by an EU member country on its sovereign debt, and recessions in an EU member country may have a significant adverse effect on the economies of EU member countries. The European financial markets have recently experienced volatility and adverse trends due to concerns about rising government debt levels of several European countries, including Greece, Spain, Ireland, Italy and Portugal. These events have adversely affected the exchange rate of the euro and may continue to significantly affect every country in Europe.

Investment in securities of Eastern European issuers involves risks not typically associated with investments in securities of issuers in more developed countries that may negatively affect the value of your investment in the Fund. Such heightened risks include, among others, expropriation and/or nationalization of assets, restrictions on and government intervention in international trade, confiscatory taxation, political instability, including authoritarian and/or military involvement in governmental decision making, armed conflict, the impact on the economy as a result of civil war, and social instability as a result of religious, ethnic and/or socioeconomic unrest.

The securities markets in Eastern Europe are underdeveloped and may be less correlated to global economic cycles than those markets located in more developed countries. As a result, securities markets in Eastern Europe are subject to greater risks associated with market volatility, lower market capitalization, lower trading volume, illiquidity, inflation, greater price fluctuations, uncertainty regarding the existence of trading markets, governmental control and heavy regulation of labor and industry. Moreover, trading on securities markets may be suspended altogether.

Real Estate Investment Risk. The Fund invests in companies that invest in, develop, or operate real estate, or provide real estate related services (“Real Estate Companies”), such as REITs, real estate holding companies, or real estate management or development companies. Investment in Real Estate Companies

exposes investors in the Fund to the risks of owning real estate directly as well as to risks that relate specifically to the way in which Real Estate Companies are organized and operated. Real estate is highly sensitive to general and local economic conditions and developments, and is characterized by intense competition and periodic overbuilding.

Risk of Investing in South Africa. South Africa’s two-tiered economy, with one rivaling developed countries and the other exhibiting many characteristics of developing countries, is characterized by uneven distribution of wealth and income and high rates of unemployment. Although economic reforms have been enacted to promote growth and foreign investments, there can be no assurance that these programs will achieve the desired results. In addition, South Africa’s inadequate currency reserves have left its currency vulnerable, at times, to devaluation. Despite significant reform and privatization, the South African government continues to control a large share of South African economic activity. Heavy regulation of labor and product markets is pervasive and may stifle South African economic growth or cause prolonged periods of recession. The agriculture and mining sectors of South Africa’s economy account for a large portion of its exports and, thus, the South African economy is susceptible to fluctuations in these commodity markets.

Portfolio Holdings Information

A description of the Trust’s policies and procedures with respect to the disclosure of the Fund’s portfolio securities is available in the Fund’s Statement of Additional Information (“SAI”). The top holdings of the Fund can be found at www.iShares.com. Fund fact sheets provide information regarding the Fund’s top holdings and may be requested by calling 1-800-iShares (1-800-474-2737).

Management

Investment Adviser. As investment adviser, BFA has overall responsibility for the general management and administration of the Trust. BFA provides an investment program for the Fund and manages the investment of the Fund’s assets. In managing the Fund, BFA may draw upon the research and expertise of its asset management affiliates with respect to certain portfolio securities. In seeking to achieve the Fund’s investment objective, BFA uses teams of portfolio managers, investment strategists and other investment specialists. This team approach brings together many disciplines and leverages BFA’s extensive resources.

Pursuant to the Investment Advisory Agreement between BFA and the Trust (entered into on behalf of the Fund), BFA is responsible for substantially all expenses of the Fund, except interest expenses, taxes, brokerage expenses, future distribution fees or expenses and extraordinary expenses.

For its investment advisory services to the Fund, BFA is entitled to receive a management fee from the Fund corresponding to the Fund’s allocable portion of an aggregate management fee based on the aggregate average daily net assets of the following iShares funds: iShares MSCI All Country Asia ex Japan Index Fund, iShares MSCI BRIC Index Fund, iShares MSCI Emerging Markets Eastern Europe Index Fund, iShares MSCI Emerging Markets Financials Sector Index Fund, iShares MSCI Emerging

Markets Index Fund, iShares MSCI Emerging Markets Materials Sector Index Fund, iShares MSCI Emerging Markets Minimum Volatility Index Fund and iShares MSCI Emerging Markets Small Cap Index Fund. The aggregate management fee is calculated as follows: 0.75% per annum of the aggregate net assets less than or equal to $14.0 billion, plus 0.68% per annum of the aggregate net assets over $14.0 billion, up to and including $28.0 billion, plus 0.61% per annum of the aggregate net assets over $28.0 billion, up to and including $42.0 billion, plus 0.56% per annum of the aggregate net assets over $42.0 billion, up to and including $56.0 billion, plus 0.50% per annum of the aggregate net assets over $56.0 billion, up to and including $70.0 billion, plus 0.45% per annum of the aggregate net assets over $70.0 billion, up to and including $84.0 billion, plus 0.40% per annum of the aggregate net assets in excess of $84.0 billion. As calculated on July 31, 2011, for its investment advisory services to the Fund, BFA is entitled to receive a management fee from the Fund, based on a percentage of the Fund’s average daily net assets, at an annual rate of 0.68%.

BFA is located at 400 Howard Street, San Francisco, CA 94105. It is a wholly owned subsidiary of BTC, which in turn is indirectly wholly-owned by BlackRock, Inc. (“BlackRock”). As of September 30, 2011, BTC and its affiliates, including BFA and BlackRock, provided investment advisory services for assets in excess of $3.35 trillion. BFA, BTC, BlackRock Execution Services, BlackRock and their affiliates deal, trade and invest for their own accounts in the types of securities in which the Fund may also invest.

A discussion regarding the basis for the Trust’s Board of Trustees’ (the “Board”) approval of the Investment Advisory Agreement with BFA is available in the Fund’s annual report for the period ended July 31.

Portfolio Managers. Christopher Bliss, Rene Casis, Diane Hsiung and Greg Savage are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager is responsible for various functions related to portfolio management, including, but not limited to, investing cash inflows, coordinating with members of his or her portfolio management team to focus on certain asset classes, implementing investment strategy, researching and reviewing investment strategy and overseeing members of his or her portfolio management team that have more limited responsibilities.

Christopher Bliss has been employed by BFA (formerly, Barclays Global Fund Advisors (“BGFA”)) and BTC (formerly, Barclays Global Investors, N.A. (“BGI”)) as a senior portfolio manager since 2005. Prior to that, Mr. Bliss was a portfolio manager from 2004 to 2005 for BGFA and BGI. Mr. Bliss has been a Portfolio Manager of the Fund since 2011.

Rene Casis has been employed by BFA and BTC as a senior portfolio manager since 2009. From 2005 to 2009, Mr. Casis was a trader at Barclays Capital. Prior to that, Mr. Casis was a portfolio manager from 2000 to 2005 for BGFA and BGI. Mr. Casis has been a Portfolio Manager of the Fund since 2010.

Diane Hsiung has been employed by BFA and BTC as a senior portfolio manager since 2007. Prior to that, Ms. Hsiung was a portfolio manager from 2002 to 2006 for BGFA and BGI. Ms. Hsiung has been a Portfolio Manager of the Fund since inception.

Greg Savage has been employed by BFA and BTC as a senior portfolio manager since 2006. Prior to that, Mr. Savage was a portfolio manager from 2001 to 2006 for BGFA and BGI. Mr. Savage has been a Portfolio Manager of the Fund since inception.

The Fund’s SAI provides additional information about the Portfolio Managers’ compensation, other accounts managed by the Portfolio Managers and the Portfolio Managers’ ownership (if any) of shares in the Fund.

Administrator, Custodian and Transfer Agent. State Street Bank and Trust Company (“State Street”) is the administrator, custodian and transfer agent for the Fund.

Conflicts of Interest. BFA wants you to know that there are certain entities with which BFA has relationships that may give rise to conflicts of interest, or the appearance of conflicts of interest. These entities include the following: BFA’s affiliates (including BlackRock and The PNC Financial Services Group, Inc., and each of their affiliates, directors, partners, trustees, managing members, officers and employees (collectively, the “Affiliates”)) and BlackRock’s significant shareholder, Barclays Bank PLC and its affiliates, including Barclays PLC (each, an “Entity” and together, the “Entities”).

The activities of BFA, the Affiliates and the Entities in the management of, or their interest in, their own accounts and other accounts they manage, may present conflicts of interest that could disadvantage the Fund and its shareholders. BFA and its Affiliates or the Entities provide investment management services to other funds and discretionary managed accounts that may follow an investment program similar to that of the Fund. BFA, its Affiliates and the Entities are involved worldwide with a broad spectrum of financial services and asset management activities and may engage in the ordinary course of business in activities in which their interests or the interests of their clients may conflict with those of the Fund. BFA, one or more of the Affiliates or the Entities acts, or may act, as an investor, investment banker, research provider, investment manager, financier, underwriter, advisor, market maker, trader, prime broker, lender, agent or principal, and have other direct and indirect interests, in securities, currencies and other instruments in which the Fund may directly or indirectly invest. Thus, it is likely that the Fund will have multiple business relationships with and will invest in, engage in transactions with, make voting decisions with respect to, or obtain services from, entities for which BFA, an Affiliate or an Entity performs or seeks to perform investment banking or other services.

BFA or one or more Affiliates or Entities may engage in proprietary trading and advise accounts and funds that have investment objectives similar to those of the Fund and/or that engage in and compete for transactions in the same types of securities, currencies and other instruments as the Fund, including in securities issued by other open-end and closed-end investment management companies, including investment companies that are affiliated with the Fund and BFA, to the extent permitted under the Investment Company Act of 1940, as amended (the “1940 Act”). The trading activities of BFA, these Affiliates and Entities are carried out without reference to positions held directly or indirectly by the Fund and may result in BFA, an Affiliate or an Entity having positions that are adverse to those of the Fund.

No Affiliate or Entity is under any obligation to share any investment opportunity, idea or strategy with the Fund. As a result, an Affiliate or an Entity may compete with the Fund for appropriate investment opportunities. As a result of this and several other factors, the results of the Fund’s investment activities may differ from those of an Affiliate or an Entity and of other accounts managed by an Affiliate or an Entity, and it is possible that the Fund could sustain losses during periods in which one or more Affiliates or Entities and other accounts achieve profits on their trading for proprietary or other accounts. The opposite result is also possible.

The Fund may, from time to time, enter into transactions in which BFA or an Affiliate’s or an Entity’s clients have an interest adverse to the Fund. Furthermore, transactions undertaken by Affiliate-advised clients may adversely impact the Fund. Transactions by one or more Affiliate- or Entity-advised clients or BFA may have the effect of diluting or otherwise disadvantaging the values, prices or investment strategies of the Fund.

An Entity may maintain securities indices as part of its product offerings. Index-based funds seek to track the performance of securities indices and may use the name of the index in the fund name. Index providers, including the Entities, may be paid licensing fees for use of their indices or index names. Entities will not be obligated to license their indices to BFA and its Affiliates, and BFA and its Affiliates will not be assured that the terms of any index licensing agreement with the Entities will be as favorable as those terms offered to other index licensees.

The Fund’s activities may be limited because of regulatory restrictions applicable to one or more Affiliates or Entities, and/or their internal policies designed to comply with such restrictions. In addition, the Fund may invest in securities of companies with which an Affiliate or an Entity has or is trying to develop investment banking relationships or in which an Affiliate or an Entity has significant debt or equity investments. The Fund also may invest in securities of companies for which an Affiliate or an Entity provides or may some day provide research coverage. An Affiliate or an Entity may have business relationships with and purchase or distribute or sell services or products from or to distributors, consultants or others who recommend the Fund or who engage in transactions with or for the Fund, and may receive compensation for such services. The Fund may also make brokerage and other payments to Affiliates or Entities in connection with the Fund’s portfolio investment transactions.

Pursuant to a securities lending program approved by the Board, the Fund has retained an Affiliate of BFA to serve as the securities lending agent for the Fund to the extent that the Fund participates in the securities lending program. For these services, the lending agent may receive a fee from the Fund, including a fee based on the returns earned on the Fund’s investment of the cash received as collateral for any loaned securities. In addition, one or more Affiliates may be among the entities to which the Fund may lend its portfolio securities under the securities lending program.

The activities of BFA, the Affiliates or Entities may give rise to other conflicts of interest that could disadvantage the Fund and its shareholders. BFA has adopted policies and procedures designed to address these potential conflicts of interest. See the Fund’s SAI for further information.

Shareholder Information

Additional shareholder information, including how to buy and sell shares of the Fund, is available free of charge by calling toll-free: 1-800-iShares (1-800-474-2737) or visiting our website at www.iShares.com.

Buying and Selling Shares. Shares of the Fund may be acquired or redeemed directly from the Fund only in Creation Units or multiples thereof, as discussed in the Creations and Redemptions section of this Prospectus. Only an Authorized Participant (as defined in the Creations and Redemptions section) may engage in creation or redemption transactions directly with the Fund. Once created, shares of the Fund generally trade in the secondary market in amounts less than a Creation Unit.

Shares of the Fund are listed on a national securities exchange for trading during the trading day. Shares can be bought and sold throughout the trading day like shares of other publicly-traded companies. The Trust does not impose any minimum investment for shares of the Fund purchased on an exchange. The Fund’s shares trade under the trading symbol “EMFN.”

Buying or selling Fund shares on an exchange involves two types of costs that may apply to all securities transactions. When buying or selling shares of the Fund through a broker, you will likely incur a brokerage commission or other charges determined by your broker. The commission is frequently a fixed amount and may be a significant proportional cost for investors seeking to buy or sell small amounts of shares. In addition, you may incur the cost of the “spread” – that is, any difference between the bid price and the ask price. The spread varies over time for shares of the Fund based on its trading volume and market liquidity, and is generally lower if the Fund has a lot of trading volume and market liquidity, and higher if the Fund has little trading volume and market liquidity.

The Board has adopted a policy of not monitoring for frequent purchases and redemptions of Fund shares (“frequent trading”) that appear to attempt to take advantage of a potential arbitrage opportunity presented by a lag between a change in the value of the Fund’s portfolio securities after the close of the primary markets for the Fund’s portfolio securities and the reflection of that change in the Fund’s NAV (“market timing”), because the Fund generally sells and redeems its shares directly through transactions that are in-kind and/or for cash, subject to the conditions described below under Creations and Redemptions. The Board has not adopted a policy of monitoring for other frequent trading activity because shares of the Fund are listed for trading on a national securities exchange.

The national securities exchange on which the Fund’s shares are listed is open for trading Monday through Friday and is closed on weekends and the following holidays: New Year’s Day, Martin Luther King, Jr. Day, Presidents’ Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day. The Fund’s primary listing exchange is NASDAQ.

Section 12(d)(1) of the 1940 Act restricts investments by investment companies in the securities of other investment companies. Registered investment companies are permitted to invest in the Fund beyond the limits set forth in Section 12(d)(1), subject to certain terms and conditions set forth in SEC rules or in an SEC exemptive order

issued to the Trust. In order for a registered investment company to invest in shares of the Fund beyond the limitations of Section 12(d)(1) pursuant to the exemptive relief obtained by the Trust, the registered investment company must enter into an agreement with the Trust.

Book Entry. Shares of the Fund are held in book-entry form, which means that no stock certificates are issued. The Depository Trust Company (“DTC”) or its nominee is the record owner of all outstanding shares of the Fund and is recognized as the owner of all shares for all purposes.

Investors owning shares of the Fund are beneficial owners as shown on the records of DTC or its participants. DTC serves as the securities depository for shares of the Fund. DTC participants include securities brokers and dealers, banks, trust companies, clearing corporations and other institutions that directly or indirectly maintain a custodial relationship with DTC. As a beneficial owner of shares, you are not entitled to receive physical delivery of stock certificates or to have shares registered in your name, and you are not considered a registered owner of shares. Therefore, to exercise any right as an owner of shares, you must rely upon the procedures of DTC and its participants. These procedures are the same as those that apply to any other securities that you hold in book-entry or “street name” form.

Share Prices. The trading prices of the Fund’s shares in the secondary market generally differ from the Fund’s daily NAV and are affected by market forces such as supply and demand, economic conditions and other factors. Information regarding the intraday value of shares of the Fund, also known as the “indicative optimized portfolio value” (“IOPV”), is disseminated every 15 seconds throughout the trading day by the national securities exchange on which the Fund’s shares are listed or by market data vendors or other information providers. The IOPV is based on the current market value of the securities and/or cash required to be deposited in exchange for a Creation Unit. The IOPV does not necessarily reflect the precise composition of the current portfolio of securities held by the Fund at a particular point in time or the best possible valuation of the current portfolio. Therefore, the IOPV should not be viewed as a “real-time” update of the Fund’s NAV, which is computed only once a day. The IOPV is generally determined by using both current market quotations and/or price quotations obtained from broker-dealers that may trade in the portfolio securities held by the Fund. The quotations of certain Fund holdings may not be updated during U.S. trading hours if such holdings do not trade in the United States. The Fund is not involved in, or responsible for, the calculation or dissemination of the IOPV and makes no representation or warranty as to its accuracy.

Determination of Net Asset Value. The NAV of the Fund normally is determined once daily Monday through Friday, generally as of the regularly scheduled close of business of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m., Eastern time) on each day that the NYSE is open for trading, based on prices at the time of closing provided that (a) any Fund assets or liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers (as detailed below) and (b) U.S. fixed income assets may be valued as of the announced closing time for trading in fixed income instruments in a particular market or exchange. The NAV

of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets held by the Fund, and its liabilities, are determined pursuant to valuation policies and procedures approved by the Board. The Fund’s assets and liabilities are valued primarily on the basis of market quotations.

Equity investments are valued at market value, which is generally determined using the last reported official closing price or last trading price on the exchange or market on which the security is primarily traded at the time of valuation.

The Fund invests in foreign securities. Foreign currency exchange rates are generally determined as of 4:00 p.m., London time. Foreign securities owned by the Fund may trade on weekends or other days when the Fund does not price its shares. As a result, the Fund’s NAV may change on days when Authorized Participants will not be able to purchase or redeem Fund shares.

Generally, trading in foreign securities, U.S. government securities, money market instruments and certain fixed-income securities is substantially completed each day at various times prior to the close of business on the NYSE. The values of such securities used in computing the NAV of the Fund are determined as of such times.

When market quotations are not readily available or are believed by BFA to be unreliable, the Fund’s investments are valued at fair value. Fair value determinations are made by BFA in accordance with policies and procedures approved by the Fund’s Board. BFA may conclude that a market quotation is not readily available or is unreliable if a security or other asset or liability does not have a price source due to its lack of liquidity, if a market quotation differs significantly from recent price quotations or otherwise no longer appears to reflect fair value, where the security or other asset or liability is thinly traded, or where there is a significant event subsequent to the most recent market quotation. A “significant event” is an event that, in the judgment of BFA, is likely to cause a material change to the closing market price of the asset or liability held by the Fund. Foreign securities whose values are affected by volatility that occurs in U.S. markets on a trading day after the close of foreign securities markets may be fair valued.

Fair value represents a good faith approximation of the value of an asset or liability. The fair value of an asset or liability held by the Fund is the amount the Fund might reasonably expect to receive from the current sale of that asset or the cost to extinguish that liability in an arm’s-length transaction. Valuing the Fund’s investments using fair value pricing will result in prices that may differ from current market valuations and that may not be the price at which those investments could have been sold during the period in which the particular fair values were used. Use of fair value prices and certain current market valuations could result in a difference between the prices used to calculate the Fund’s NAV and the prices used by the Underlying Index, which, in turn, could result in a difference between the Fund’s performance and the performance of the Underlying Index.

The value of assets or liabilities denominated in non-U.S. currencies will be converted into U.S. dollars using exchange rates deemed appropriate by BFA as investment

adviser. Use of a rate different from the rate used by the Index Provider may adversely affect the Fund’s ability to track the Underlying Index.

Dividends and Distributions

General Policies. Dividends from net investment income, if any, generally are declared and paid semi-annually by the Fund. Distributions of net realized securities gains, if any, generally are declared and paid once a year, but the Trust may make distributions on a more frequent basis for the Fund. The Trust reserves the right to declare special distributions if, in its reasonable discretion, such action is necessary or advisable to preserve its status as a regulated investment company (“RIC”) or to avoid imposition of income or excise taxes on undistributed income or realized gains.

Dividends and other distributions on shares of the Fund are distributed on a pro rata basis to beneficial owners of such shares. Dividend payments are made through DTC participants and indirect participants to beneficial owners then of record with proceeds received from the Fund.

Dividend Reinvestment Service. No dividend reinvestment service is provided by the Trust. Broker-dealers may make available the DTC book-entry Dividend Reinvestment Service for use by beneficial owners of the Fund for reinvestment of their dividend distributions. Beneficial owners should contact their broker to determine the availability and costs of the service and the details of participation therein. Brokers may require beneficial owners to adhere to specific procedures and timetables. If this service is available and used, dividend distributions of both income and realized gains will be automatically reinvested in additional whole shares of the Fund purchased in the secondary market.

Taxes. As with any investment, you should consider how your investment in shares of the Fund will be taxed. The tax information in this Prospectus is provided as general information, based on current law. You should consult your own tax professional about the tax consequences of an investment in shares of the Fund.

Unless your investment in Fund shares is made through a tax-exempt entity or tax-deferred retirement account, such as an IRA, you need to be aware of the possible tax consequences when the Fund makes distributions or you sell Fund shares.

Taxes on Distributions. Distributions from the Fund’s net investment income (other than qualified dividend income), including distributions of income from securities lending and distributions out of the Fund’s net short-term capital gains, if any, are taxable to you as ordinary income. Distributions by the Fund of net long-term capital gains in excess of net short-term capital losses (capital gain dividends) are taxable to you as long-term capital gains, generally at a 15% tax rate (0% at certain income levels), regardless of how long you have held the Fund’s shares. Distributions by the Fund that qualify as qualified dividend income are taxable to you at long-term capital gain rates for taxable years beginning on or before December 31, 2012. The 15% and 0% tax rates expire for taxable years beginning after December 31, 2012. Maximum long-term capital gain income tax rates are scheduled to rise to 20% in 2013. Beginning in 2013, a 3.8% U.S. federal Medicare contribution tax will be imposed on “net investment income,” including interest, dividends, and capital gains, of U.S.

individuals with income exceeding $200,000 (or $250,000 if married and filing jointly), and of estates and trusts.

Dividends will be qualified dividend income to you if they are attributable to qualified dividend income received by the Fund. Generally, qualified dividend income includes dividend income from taxable U.S. corporations and qualified non-U.S. corporations, provided that the Fund satisfies certain holding period requirements in respect of the stock of such corporations and has not hedged its position in the stock in certain ways. Substitute dividends received by the Fund with respect to dividends paid on securities lent out will not be qualified dividend income. For this purpose, a qualified non-U.S. corporation means any non-U.S. corporation that is eligible for benefits under a comprehensive income tax treaty with the United States, which includes an exchange of information program or if the stock with respect to which the dividend was paid is readily tradable on an established United States securities market. The term excludes a corporation that is a passive foreign investment company.

Dividends received by the Fund from a REIT or another RIC generally are qualified dividend income only to the extent the dividend distributions are made out of qualified dividend income received by such REIT or RIC. It is expected that dividends received by the Fund from a REIT and distributed to a shareholder generally will be taxable to the shareholder as ordinary income.

For a dividend to be treated as qualified dividend income, the dividend must be received with respect to a share of stock held without being hedged by the Fund, and with respect to a share of the Fund held without being hedged by you, for 61 days during the 121-day period beginning at the date which is 60 days before the date on which such share becomes ex-dividend with respect to such dividend or, in the case of certain preferred stock, 91 days during the 181-day period beginning 90 days before such date.

If your Fund shares are loaned out pursuant to a securities lending arrangement, you may lose the ability to use foreign tax credits passed through by the Fund or to treat Fund dividends paid while the shares are held by the borrower as qualified dividend income.

In general, your distributions are subject to U.S. federal income tax for the year when they are paid. Certain distributions paid in January, however, may be treated as paid on December 31 of the prior year.

If the Fund’s distributions exceed current and accumulated earnings and profits, all or a portion of the distributions made in the taxable year may be recharacterized as a return of capital to shareholders. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and result in a higher capital gain or lower capital loss when those shares on which the distribution was received are sold. Once a shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain, if the shareholder holds shares of the Fund as capital assets.

If you are neither a resident nor a citizen of the United States or if you are a non-U.S. entity, the Fund’s ordinary income dividends (which include distributions of net short-term capital gains) will generally be subject to a 30% U.S. withholding tax, unless a lower treaty rate applies, provided that withholding tax will generally not apply to any

gain or income realized by a non-U.S. shareholder in respect of any distributions of long-term capital gains or upon the sale or other disposition of shares of the Fund.

A 30% withholding tax will be imposed on dividends paid after December 31, 2013, and redemption proceeds paid after December 31, 2014, to (i) foreign financial institutions including non-U.S. investment funds unless they agree to collect and disclose to the Internal Revenue Service (“IRS”) information regarding their direct and indirect U.S. account holders and (ii) certain other foreign entities, unless they certify certain information regarding their direct and indirect U.S. owners. To avoid withholding, foreign financial institutions will need to enter into agreements with the IRS that state that they will provide the IRS information, including the name, address and taxpayer identification number of direct and indirect U.S. account holders, comply with due diligence procedures with respect to the identification of U.S. accounts, report to the IRS certain information with respect to U.S. accounts maintained, agree to withhold tax on certain payments made to non-compliant foreign financial institutions or to account holders who fail to provide the required information, and determine certain other information as to their account holders. Other foreign entities will need to provide the name, address, and taxpayer identification number of each substantial U.S. owner or certifications of no substantial U.S. ownership unless certain exceptions apply.

Dividends, interest and capital gains earned by the Fund with respect to non-U.S. securities may give rise to withholding and other taxes imposed by non-U.S. countries. Tax conventions between certain countries and the United States may reduce or eliminate such taxes. If more than 50% of the total assets of the Fund at the close of a year consists of non-U.S. stocks or securities, the Fund may “pass through” to you certain non-U.S. income taxes (including withholding taxes) paid by the Fund. This means that you would be considered to have received as an additional dividend your share of such non-U.S. taxes, but you may be entitled to either a corresponding tax deduction in calculating your taxable income, or, subject to certain limitations, a credit in calculating your U.S. federal income tax.

For purposes of foreign tax credits for U.S. shareholders of the Fund, foreign capital gains taxes may not produce associated foreign source income, thereby limiting a U.S. person’s ability to use such credits.

If you are a resident or a citizen of the United States, by law, back-up withholding will apply to your distributions and proceeds if you have not provided a taxpayer identification number or social security number and made other required certifications.

Taxes When Shares are Sold. Currently, any capital gain or loss realized upon a sale of Fund shares is generally treated as a long-term gain or loss if the shares have been held for more than one year. Any capital gain or loss realized upon a sale of Fund shares held for one year or less is generally treated as short-term gain or loss, except that any capital loss on the sale of shares held for six months or less is treated as long-term capital loss to the extent that capital gain dividends were paid with respect to such shares. Beginning in 2013, any such capital gains, including from sales of Fund shares or from capital gain dividends, will be included in “net investment income” for purposes of the 3.8% U.S. federal Medicare contribution tax mentioned above.

The foregoing discussion summarizes some of the consequences under current U.S. federal tax law of an investment in the Fund. It is not a substitute for personal tax advice. You may also be subject to state and local taxation on Fund distributions and sales of shares. Consult your personal tax adviser about the potential tax consequences of an investment in shares of the Fund under all applicable tax laws.

Creations and Redemptions. Prior to trading in the secondary market, shares of the Fund are “created” at NAV by market makers, large investors and institutions only in block-size Creation Units of 50,000 shares or multiples thereof. Each “creator” or “Authorized Participant” enters into an authorized participant agreement with the Fund’s distributor, SEI Investments Distribution Co. (the “Distributor”). Only an Authorized Participant may create or redeem Creation Units directly with the Fund. A creation transaction, which is subject to acceptance by the transfer agent, generally takes place when an Authorized Participant deposits into the Fund a designated portfolio of securities and a specified amount of cash approximating the holdings of the Fund in exchange for a specified number of Creation Units. To the extent practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund.

Similarly, shares can be redeemed only in Creation Units, generally for a designated portfolio of securities and a specified amount of cash held by the Fund (“Fund Securities”). Except when aggregated in Creation Units, shares are not redeemable by the Fund. The prices at which creations and redemptions occur are based on the next calculation of NAV after an order is received in a form described in the authorized participant agreement.

The Fund intends to comply with the U.S. federal securities laws in accepting securities for deposit and satisfying redemptions with redemption securities by, among other means, assuring that any securities accepted for deposit and any securities used to satisfy redemption requests will be sold in transactions that would be exempt from registration under the Securities Act of 1933, as amended (the “1933 Act”). Further, an Authorized Participant that is not a “qualified institutional buyer,” as such term is defined under Rule 144A of the 1933 Act, will not be able to receive Fund Securities that are restricted securities eligible for resale under Rule 144A.

Creations and redemptions must be made through a firm that is either a member of the Continuous Net Settlement System of the National Securities Clearing Corporation or a DTC participant and has executed an agreement with the Distributor with respect to creations and redemptions of Creation Unit aggregations. Information about the procedures regarding creation and redemption of Creation Units (including the cut-off times for receipt of creation and redemption orders) is included in the Fund’s SAI.

Because new shares may be created and issued on an ongoing basis, at any point during the life of the Fund a “distribution,” as such term is used in the 1933 Act, may be occurring. Broker-dealers and other persons are cautioned that some activities on their part may, depending on the circumstances, result in their being deemed participants in a distribution in a manner that could render them statutory underwriters and subject to the prospectus delivery and liability provisions of the 1933 Act. Any determination of whether one is an underwriter must take into account all the relevant facts and circumstances of each particular case.

Broker-dealers should also note that dealers who are not “underwriters” but are participating in a distribution (as contrasted to ordinary secondary transactions), and thus dealing with shares that are part of an “unsold allotment” within the meaning of Section 4(3)(C) of the 1933 Act, would be unable to take advantage of the prospectus delivery exemption provided by Section 4(3) of the 1933 Act. For delivery of prospectuses to exchange members, the prospectus delivery mechanism of Rule 153 under the 1933 Act is available only with respect to transactions on a national securities exchange.

Costs Associated with Creations and Redemptions. Authorized Participants are charged standard creation and redemption transaction fees to offset transfer and other transaction costs associated with the issuance and redemption of Creation Units. The standard creation and redemption transaction fees are set forth in the table below. The standard creation transaction fee is charged to the Authorized Participant on the day such Authorized Participant creates a Creation Unit, and is the same regardless of the number of Creation Units purchased by the Authorized Participant on the applicable business day. Similarly, the standard redemption transaction fee is charged to the Authorized Participant on the day such Authorized Participant redeems a Creation Unit, and is the same regardless of the number of Creation Units redeemed by the Authorized Participant on the applicable business day. Creations and redemptions for cash (when cash creations and redemptions (in whole or in part) are available or specified) are also subject to an additional charge (up to the maximum amounts shown in the table below). This charge is intended to compensate for brokerage, tax, foreign exchange, execution, market impact and other costs and expenses related to cash transactions. Investors who use the services of a broker or other financial intermediary may pay fees for such services.

The following table shows, as of September 30, 2011, the approximate value of one Creation Unit, standard fees and maximum additional charges for creations and redemptions (as described above):

Householding. Householding is an option available to certain Fund investors. Householding is a method of delivery, based on the preference of the individual investor, in which a single copy of certain shareholder documents can be delivered to investors who share the same address, even if their accounts are registered under different names. Please contact your broker-dealer if you are interested in enrolling in householding and receiving a single copy of prospectuses and other shareholder documents, or if you are currently enrolled in householding and wish to change your householding status.

Distribution

The Distributor distributes Creation Units for the Fund on an agency basis. The Distributor does not maintain a secondary market in shares of the Fund. The Distributor has no role in determining the policies of the Fund or the securities that are purchased or sold by the Fund. The Distributor’s principal address is One Freedom Valley Drive, Oaks, PA 19456.

In addition, BFA or its Affiliates make payments to broker-dealers, banks or other financial intermediaries (together, “intermediaries”) related to marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems, or their making shares of the Fund and certain other iShares funds available to their customers. Such payments, which may be significant to the intermediary, are not made by the Fund. Rather, such payments are made by BFA or its Affiliates from their own resources, which come directly or indirectly in part from fees paid by the iShares funds complex. Payments of this type are sometimes referred to as revenue-sharing payments. A financial intermediary may make decisions about which investment options it recommends or makes available, or the level of services provided, to its customers based on the revenue-sharing payments it is eligible to receive. Therefore, such payments to an intermediary create conflicts of interest between the intermediary and its customers and may cause the intermediary to recommend the Fund or other iShares funds over another investment. More information regarding these payments is contained in the Fund’s SAI. Please contact your salesperson or other investment professional for more information regarding any such payments his or her firm may receive from BFA or its Affiliates.

Financial Highlights

The financial highlights table is intended to help investors understand the Fund’s financial performance since inception. Certain information reflects financial results for a single share of the Fund. The total returns in the table represent the rate that an investor would have earned (or lost) on an investment in the Fund, assuming reinvestment of all dividends and distributions. This information has been audited by PricewaterhouseCoopers LLP, whose report is included, along with the Fund’s financial statements, in the Fund’s Annual Report (available upon request).

Supplemental Information

I. Premium/Discount Information

The table that follows presents information about the differences between the daily market price on secondary markets for shares of the Fund and the Fund’s NAV. NAV is the price at which the Fund issues and redeems shares. It is calculated in accordance with the standard formula for valuing mutual fund shares. The price used to calculate market returns (“Market Price”) of the Fund generally is determined using the midpoint between the highest bid and the lowest offer on the primary securities exchange on which shares of the Fund are listed for trading, as of the time that the Fund’s NAV is calculated. The Fund’s Market Price may be at, above or below its NAV. The NAV of the Fund will fluctuate with changes in the value of its portfolio holdings. The Market Price of the Fund will fluctuate in accordance with changes in its NAV, as well as market supply and demand.

Premiums or discounts are the differences (expressed as a percentage) between the NAV and Market Price of the Fund on a given day, generally at the time the NAV is calculated. A premium is the amount that the Fund is trading above the reported NAV, expressed as a percentage of the NAV. A discount is the amount that the Fund is trading below the reported NAV, expressed as a percentage of the NAV.

The following information shows the frequency of distributions of premiums and discounts for the Fund from April 1, 2010 through September 30, 2011.

Each line in the table shows the number of trading days in which the Fund traded within the premium/discount range indicated. The number of trading days in each premium/discount range is also shown as a percentage of the total number of trading days in the period covered by the table. All data presented here represents past performance, which cannot be used to predict future results.

II. Total Return Information

The table that follows presents information about the total returns of the Fund and the Underlying Index as of the fiscal year ended July 31, 2011.

“Average Annual Total Returns” represent the average annual change in value of an investment over the periods indicated. “Cumulative Total Returns” represent the total change in value of an investment over the period indicated.

The Fund’s NAV is the value of one share of the Fund as calculated in accordance with the standard formula for valuing mutual fund shares. The NAV return is based on the NAV of the Fund and the market return is based on the Market Price of the Fund. Market Price is determined by using the midpoint between the highest bid and the lowest offer on the primary stock exchange on which shares of the Fund are listed for trading, as of the time that the Fund’s NAV is calculated. Since shares of the Fund did not trade in the secondary market until after the Fund’s inception, for the period from inception to the first day of secondary market trading in shares of the Fund, the NAV of the Fund is used as a proxy for the Market Price to calculate market returns. Market and NAV returns assume that dividends and capital gain distributions have been reinvested in the Fund at Market Price and NAV, respectively.

An index is a statistical composite that tracks a specified financial market or sector. Unlike the Fund, the Underlying Index does not actually hold a portfolio of securities and therefore does not incur the expenses incurred by the Fund. These expenses negatively impact the performance of the Fund. Also, market returns do not include brokerage commissions that may be payable on secondary market transactions. If brokerage commissions were included, market returns would be lower. The returns shown in the following table do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption or sale of Fund shares. The investment return and principal value of shares of the Fund will vary with changes in market conditions. Shares of the Fund may be worth more or less than their original cost when they are redeemed or sold in the market. The Fund’s past performance is no guarantee of future results.

Fund Overview

iSHARES® MSCI EMERGING MARKETS MATERIALS SECTOR INDEX FUND

Ticker: EMMT Stock Exchange: NASDAQ

Investment Objective

The iShares MSCI Emerging Markets Materials Sector Index Fund (the “Fund”) seeks investment results that correspond generally to the price and yield performance, before fees and expenses, of the MSCI Emerging Markets Materials Index (the “Underlying Index”).

Fees and Expenses

The following table describes the fees and expenses that you will incur if you own shares of the Fund. The investment advisory agreement between iShares Trust (the “Trust”) and BlackRock Fund Advisors (“BFA”) (the “Investment Advisory Agreement”) provides that BFA will pay all operating expenses of the Fund, except interest expenses, taxes, brokerage expenses, future distribution fees or expenses, and extraordinary expenses.

You may also incur usual and customary brokerage commissions when buying or selling shares of the Fund, which are not reflected in the example that follows:

Annual Fund Operating Expenses

Example. This Example is intended to help you compare the cost of owning shares of the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

Portfolio Turnover. The Fund may pay transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 6% of the average value of its portfolio.

Principal Investment Strategies

The Underlying Index is a free float-adjusted market capitalization-weighted index designed to measure the combined equity market performance of the material sector of emerging markets countries. Component securities include those of chemical, construction materials, containers and packaging, metals and mining, and paper and forest products companies. As of September 30, 2011, the Underlying Index consisted of companies in the following countries: Brazil, Chile, China, Colombia, India, Indonesia, Malaysia, Mexico, Peru, Poland, Russia, South Africa, South Korea, Taiwan, Thailand and Turkey (together, the “emerging markets materials sector countries”). As of September 30, 2011, the Underlying Index was comprised of 124 securities.

BFA uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to “beat” the index it tracks and does not seek temporary defensive positions when markets decline or appear overvalued.

Indexing may eliminate the chance that the Fund will substantially outperform the Underlying Index but also may reduce some of the risks of active management, such as poor security selection. Indexing seeks to achieve lower costs and better after-tax performance by keeping portfolio turnover low in comparison to actively managed investment companies.

BFA uses a representative sampling indexing strategy to manage the Fund. “Representative sampling” is an indexing strategy that involves investing in a representative sample of securities that collectively has an investment profile similar to the Underlying Index. The securities selected are expected to have, in the aggregate, investment characteristics (based on factors such as market capitalization and industry weightings), fundamental characteristics (such as return variability and yield) and liquidity measures similar to those of the Underlying Index. The Fund may or may not hold all of the securities in the Underlying Index.

The Fund generally invests at least 90% of its assets in securities of the Underlying Index and in depositary receipts representing securities of the Underlying Index. The Fund may invest the remainder of its assets in securities not included in the Underlying Index, but which BFA believes will help the Fund track the Underlying Index and in other investments including futures contracts, options on futures contracts, options and swaps as well as cash and cash equivalents, including shares of money market funds advised by BFA or its affiliates.

The Fund may lend securities representing up to one-third of the

S-2   


Table Of Contents



value of the Fund’s total assets (including the value of the collateral received).

The Underlying Index is sponsored by an organization (the “Index Provider”) that is independent of the Fund and BFA. The Index Provider determines the composition and relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index. The Fund’s Index Provider is MSCI Inc. (“MSCI”).

Industry Concentration Policy. The Fund will concentrate its investments (i.e., hold 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. For purposes of this limitation, securities of the U.S. government (including its agencies and instrumentalities) and repurchase agreements collateralized by U.S. government securities are not considered to be issued by members of any industry.

Summary of Principal Risks

As with any investment, you could lose all or part of your investment in the Fund, and the Fund’s performance could trail that of other investments. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund’s net asset value per share (“NAV”), trading price, yield, total return and ability to meet its investment objective.

Asset Class Risk. Securities in the Underlying Index or in the Fund’s portfolio may underperform in comparison to the general securities markets or other asset classes.

Commodity Exposure Risk. The Fund invests in companies that produce commodities and are, therefore, susceptible to fluctuations in certain commodity markets. Any negative changes in commodity markets could have an adverse impact on those companies.

Concentration Risk. To the extent that the Fund’s investments are concentrated in a particular issuer, region, country, market, industry or asset class, the Fund may be susceptible to loss due to adverse occurrences affecting that issuer, region, country, market, industry or asset class.

Currency Risk. Because the Fund’s NAV is determined in U.S. dollars, the Fund’s NAV could decline if the currency of a non-U.S. market in which the Fund invests depreciates against the U.S. dollar.

Custody Risk. Less developed markets are more likely to experience problems with the clearing and settling of trades and the holding of securities by local banks, agents and depositories.

Emerging Markets Risk. The Fund’s investments in emerging markets may be subject to a greater risk of loss than investments in more developed markets. Emerging markets may be more likely to experience inflation risk, political turmoil and rapid changes in economic conditions than more developed markets. Emerging markets often have less uniformity in accounting and reporting requirements, unreliable securities valuation and greater risk associated with custody of securities.

Equity Securities Risk. Equity securities are subject to changes in value and their values may be more volatile than other asset classes.

Geographic Risk. A natural or other disaster could occur in a geographic region in which the Fund invests, which could affect the economy or particular business operations of companies in the specific geographic region, causing an adverse impact on the Fund’s investments in the affected region.

Issuer Risk. Fund performance depends on the performance of individual securities to which the Fund has exposure. Changes to the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA’s investment management strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares, losses from trading in secondary markets, periods of high volatility and disruption in the creation/redemption process of the Fund. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV.

Materials Sector Risk. Companies in the materials sector may be adversely impacted by the volatility of commodity prices, exchange rates, depletion of resources, over-production, litigation and government regulations, among other factors.

Metals and Mining Sector Risk. Companies in the metals and mining sector are susceptible to fluctuations in worldwide metal prices, and exploration and production costs. In addition, metals and mining companies may have significant operations in areas at risk for social and political unrest, security concerns and environmental damage. These companies may also be at risk for increased government regulation and intervention. As a result, such risks may adversely affect the issuers to which the Fund has exposure.

Mid-Capitalization Companies Risk. The Fund may invest in the securities of mid-capitalization companies. Compared to large-capitalization companies, mid-capitalization companies may be less stable and more susceptible to adverse developments and their securities may be more volatile and less liquid.

Non-Diversification Risk. The Fund may invest a large percentage of its assets in securities issued by or representing a small number of issuers. As a result, the Fund’s performance may depend on the performance of a small number of issuers.

Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers are subject to the risks associated with investing in those non-U.S. markets, such as heightened risks of inflation or nationalization. The Fund may lose money due to political, economic and geographic events affecting a non-U.S. issuer or market. The Fund is specifically exposed to Asian Economic Risk and Central and South American Economic Risk.

Passive Investment Risk. The Fund is not actively managed and BFA does not attempt to take defensive positions

S-4   


Table Of Contents



under any market conditions, including declining markets.

Privatization Risk. Some countries in which the Fund invests have begun a process of privatizing certain entities and industries. Privatized entities may lose money or be re-nationalized.

Reliance on Trading Partners Risk. The Fund invests in countries whose economies are heavily dependent upon trading with key partners. Any reduction in this trading may have an adverse impact on the Fund’s investments. Through its trading partners, the Fund is particularly exposed to U.S. Trading Partner Risk.

Risk of Investing in Brazil. Investment in Brazilian issuers involves risks that are specific to Brazil, including legal, regulatory, political and economic risks. As a result, such risks may adversely affect the value of the Fund’s investments.

Risk of Investing in Eastern Europe. The Fund’s investments in Eastern European issuers may subject the Fund to legal, regulatory, political, security, currency and economic risks specific to Eastern Europe, which may adversely affect the value of the Fund’s investments.

Securities Lending Risk. The Fund may engage in securities lending. Securities lending involves the risk that the Fund may lose money because the borrower of the Fund’s loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Security Risk. Some countries and regions in which the Fund invests have experienced security concerns. Incidents involving a country’s or region’s security may cause uncertainty in these markets and may adversely affect their economies and the Fund’s investments.

Small-Capitalization Companies Risk. The Fund may invest in the securities of small-capitalization companies. Compared to mid- and large-capitalization companies, small-capitalization companies may be less stable and more susceptible to adverse developments and their securities may be more volatile and less liquid.

Structural Risk. The countries in which the Fund invests may be subject to considerable degrees of economic, political and social instability.

Tracking Error Risk. The performance of the Fund may diverge from that of the Underlying Index. Because the Fund employs a representative sampling strategy, the Fund may experience tracking error to a greater extent than a fund that seeks to replicate an index. BFA EXPECTS THAT THE FUND MAY EXPERIENCE HIGHER TRACKING ERROR THAN IS TYPICAL FOR SIMILAR INDEX EXCHANGE-TRADED FUNDS.

Valuation Risk. The value of the securities in the Fund’s portfolio may change on days when shareholders will not be able to purchase or sell the Fund’s shares.

Performance Information

As of the date of the Fund’s prospectus (the “Prospectus”), the Fund has been in operation for less than one full calendar year and therefore does not report its performance information.

Management

Investment Adviser. BlackRock Fund Advisors.

Portfolio Managers. Christopher Bliss, Rene Casis, Diane Hsiung and Greg Savage (the “Portfolio Managers”) are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager supervises a portfolio management team. Mr. Bliss has been a Portfolio Manager of the Fund since 2011. Mr. Casis has been a Portfolio Manager of the Fund since 2010. Ms. Hsiung and Mr. Savage have been Portfolio Managers of the Fund since inception.

Purchase and Sale of Fund Shares

The Fund is an exchange-traded fund (commonly referred to as an “ETF”). Individual Fund shares may only be purchased and sold on a national securities exchange through a broker-dealer. The price of Fund shares is based on market price, and because ETF shares trade at market prices rather than NAV, shares may trade at a price greater than NAV (a premium) or less than NAV (a discount). The Fund will only issue or redeem shares that have been aggregated into blocks of 50,000 shares or multiples thereof (“Creation Units”) to authorized participants who have entered into agreements with the Fund’s distributor. The Fund generally will issue or redeem Creation Units in return for a designated portfolio of securities (and an amount of cash) that the Fund specifies each day.

Tax Information

The Fund intends to make distributions that may be taxable to you as ordinary income or capital gains, unless you are investing through a tax-deferred arrangement such as a 401(k) plan or an individual retirement account (“IRA”).

Payments to Broker-Dealers and other Financial Intermediaries

If you purchase shares of the Fund through a broker-dealer or other financial intermediary (such as a bank), BFA or other related companies may pay the intermediary for marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems or other services related to the sale or promotion of the Fund. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.

More Information About the Fund

This Prospectus contains important information about investing in the Fund. Please read this Prospectus carefully before you make any investment decisions. Additional information regarding the Fund is available at www.iShares.com.

BFA is the investment adviser to the Fund. Shares of the Fund are listed for trading on The NASDAQ Stock Market (“NASDAQ”). The market price for a share of the Fund may be different from the Fund’s most recent NAV.

ETFs are funds that trade like other publicly-traded securities. The Fund is designed to track an index. Similar to shares of an index mutual fund, each share of the Fund represents a partial ownership in an underlying portfolio of securities intended to track a market index. Unlike shares of a mutual fund, which can be bought and redeemed from the issuing fund by all shareholders at a price based on NAV, shares of the Fund may be purchased or redeemed directly from the Fund at NAV solely by authorized participants. Also unlike shares of a mutual fund, shares of the Fund are listed on a national securities exchange and trade in the secondary market at market prices that change throughout the day.

The Fund invests in a particular segment of the securities markets and seeks to track the performance of a securities index that generally is not representative of the market as a whole. The Fund is designed to be used as part of broader asset allocation strategies. Accordingly, an investment in the Fund should not constitute a complete investment program.

An index is a theoretical financial calculation while the Fund is an actual investment portfolio. The performance of the Fund and the Underlying Index may vary due to transaction costs, non-U.S. currency valuations, asset valuations, corporate actions (such as mergers and spin-offs), timing variances and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions (such as diversification requirements) that apply to the Fund but not to the Underlying Index or to the use of representative sampling. “Tracking error” is the difference between the performance (return) of the Fund’s portfolio and that of the Underlying Index. BFA expects that, over time, the Fund’s tracking error will not exceed 5%. Because the Fund uses a representative sampling indexing strategy, it can be expected to have a larger tracking error than if it used a replication indexing strategy. “Replication” is an indexing strategy in which a fund invests in substantially all of the securities in its underlying index in approximately the same proportions as in the underlying index.

An investment in the Fund is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, BFA or any of its affiliates.

The Fund’s investment objective and the Underlying Index may be changed without shareholder approval.

A Further Discussion of Principal Risks

The Fund is subject to various risks, including the principal risks noted below, any of which may adversely affect the Fund’s NAV, trading price, yield, total return and ability to meet its investment objective. You could lose all or part of your investment in the Fund, and the Fund could underperform other investments.

Asian Economic Risk. Certain Asian economies have experienced over-extension of credit, currency devaluations and restrictions, high unemployment, high inflation, decreased exports and economic recessions. Economic events in any one Asian country may have a significant economic effect on the entire Asian region, as well as on major trading partners outside Asia, and any adverse event in the Asian markets may have a significant adverse effect on some or all of the materials sectors of emerging markets countries in which the Fund invests.

Asset Class Risk. The securities in the Underlying Index or in the Fund’s portfolio may underperform the returns of other securities or indexes that track other countries, groups of countries, regions, industries, groups of industries, markets, asset classes or sectors. Various types of securities or indexes tend to experience cycles of outperformance and underperformance in comparison to the general securities markets.

Central and South American Economic Risk. The economies and materials sectors of certain emerging markets countries are affected by the economies of Central and South American countries, some of which have experienced high interest rates, economic volatility, inflation, currency devaluations, government defaults and high unemployment rates. In addition, commodities (such as oil, gas and minerals) represent a significant percentage of the region’s exports and many economies in this region are particularly sensitive to fluctuations in commodity prices. Adverse economic events in one country may have a significant adverse effect on some or all of the materials sectors of emerging markets countries.

Commodity Exposure Risk. Economies and companies whose performance is reflected in the Fund’s portfolio or Underlying Index may be adversely affected by changes or trends in commodity prices. Commodity prices may be influenced or characterized by unpredictable factors, including, where applicable, high volatility, changes in supply and demand relationships, weather, agriculture, trade, pestilence, political instability, changes in interest rates and monetary and other governmental policies, action and inaction. Securities of companies held by the Fund that are dependent on a single commodity, or are concentrated in a single commodity sector, may typically exhibit even higher volatility attributable to commodity prices.

Concentration Risk. To the extent that the Fund’s portfolio reflects the Underlying Index’s concentration in the securities of a particular issuer or issuers in a particular country, group of countries, region, market, industry, group of industries, sector or asset class, the Fund may be adversely affected by the performance of those securities, may be subject to increased price volatility and may be more susceptible to adverse economic, market, political or regulatory occurrences affecting that issuer, country, group of countries, region, market, industry, group of industries, sector or asset class.

Currency Risk. Because the Fund’s NAV is determined on the basis of the U.S. dollar, investors may lose money if the currency of a non-U.S. market in which the Fund invests depreciates against the U.S. dollar, even if the local currency value of the Fund’s holdings in that market increases.

Custody Risk. Custody risk refers to the risks inherent in the process of clearing and settling trades and the holding of securities by local banks, agents and depositories. Low trading volumes and volatile prices in less developed markets may make trades harder to complete and settle, and governments or trade groups may compel local agents to hold securities in designated depositories that are not subject to independent evaluation. Local agents are held only to the standards of care of their local markets. In general, the less developed a country’s securities market is, the greater the likelihood of custody problems.

Emerging Markets Risk. Investments in emerging markets are subject to a greater risk of loss than investments in more developed markets. This is due to, among other things, the potential for greater market volatility, lower trading volume, inflation, political and economic instability, greater risk of a market shutdown and more governmental limitations on foreign investments than typically found in more developed markets. In addition, emerging markets often have less uniformity in accounting and reporting requirements, unreliable securities valuation and greater risks associated with custody of securities.

Equity Securities Risk. The Fund invests in equity securities, which are subject to changes in value that may be attributable to market perception of a particular issuer or to general stock market fluctuations that affect all issuers. Investments in equity securities may be more volatile than investments in other asset classes.

Geographic Risk. Some markets in which the Fund invests are located in parts of the world that have historically been prone to natural disasters, such as earthquakes, volcanoes, droughts, floods, hurricanes and tsunamis, and are economically sensitive to environmental events. Any natural or other disaster could have a significant adverse impact on the economies of these geographic areas, causing an adverse impact on the Fund’s investments in the affected region.

Issuer Risk. The performance of the Fund depends on the performance of individual securities to which the Fund has exposure. Any issuer of these securities may perform poorly, causing the value of its securities to decline. Poor performance may be caused by poor management decisions, competitive pressures, changes in technology, expiration of patent protection, disruptions in supply, labor problems or shortages, corporate restructurings, fraudulent disclosures or other factors. Issuers may, in times of distress or at their own discretion, decide to reduce or eliminate dividends, which may also cause their stock prices to decline.

Management Risk. The Fund may not fully replicate the Underlying Index and may hold securities not included in the Underlying Index. As a result, the Fund is subject to the risk that BFA’s investment management strategy, the implementation of which is subject to a number of constraints, may not produce the intended results.

Market Risk. The Fund could lose money due to short-term market movements and over longer periods during market downturns. Securities may decline in value due to

factors affecting securities markets generally or particular industries represented in the markets. The value of a security may decline due to general market conditions, economic trends or events that are not specifically related to the issuer of the security or to factors that affect a particular industry or industries. During a general downturn in the securities markets, multiple asset classes may be negatively affected.

Market Trading Risk

Absence of Active Market. Although shares of the Fund are listed for trading on one or more stock exchanges, there can be no assurance that an active trading market for such shares will develop or be maintained.

Risk of Secondary Listings. The Fund’s shares may be listed or traded on U.S. and non-U.S. stock exchanges other than the U.S. stock exchange where the Fund’s primary listing is maintained. There can be no assurance that the Fund’s shares will continue to trade on any such stock exchange or in any market or that the Fund’s shares will continue to meet the requirements for listing or trading on any exchange or in any market. The Fund’s shares may be less actively traded in certain markets than others, and investors are subject to the execution and settlement risks and market standards of the market where they or their broker direct their trades for execution. Certain information available to investors who trade Fund shares on a U.S. stock exchange during regular U.S. market hours may not be available to investors who trade in other markets, which may result in secondary market prices in such markets being less efficient.

Secondary Market Trading Risk. Shares of the Fund may trade in the secondary market at times when the Fund does not accept orders to purchase or redeem shares. At such times, shares may trade in the secondary market with more significant premiums or discounts than might be experienced at times when the Fund accepts purchase and redemption orders.

Secondary market trading in Fund shares may be halted by a stock exchange because of market conditions or other reasons. In addition, trading in Fund shares on a stock exchange or in any market may be subject to trading halts caused by extraordinary market volatility pursuant to “circuit breaker” rules on the stock exchange or market. There can be no assurance that the requirements necessary to maintain the listing or trading of Fund shares will continue to be met or will remain unchanged.

Shares of the Fund May Trade at Prices Other Than NAV. Shares of the Fund trade on stock exchanges at prices at, above or below their most recent NAV. The NAV of the Fund is calculated at the end of each business day and fluctuates with changes in the market value of the Fund’s holdings since the most recent calculation. The trading prices of the Fund’s shares fluctuate continuously throughout trading hours based on market supply and demand rather than NAV. The trading prices of the Fund’s shares may deviate significantly from NAV during periods of market volatility. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV. However, because shares can be created and redeemed in Creation Units at NAV (unlike shares of many closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their NAVs), BFA believes that large discounts or premiums to the NAV of the Fund are not

likely to be sustained over the long-term. While the creation/redemption feature is designed to make it likely that the Fund’s shares normally will trade on stock exchanges at prices close to the Fund’s next calculated NAV, exchange prices are not expected to correlate exactly with the Fund’s NAV due to timing reasons as well as market supply and demand factors. In addition, disruptions to creations and redemptions or extreme market volatility may result in trading prices for shares of the Fund that differ significantly from its NAV.

Costs of Buying or Selling Fund Shares. Buying or selling Fund shares on an exchange involves two types of costs that apply to all securities transactions. When buying or selling shares of the Fund through a broker, you will likely incur a brokerage commission or other charges imposed by brokers as determined by that broker. In addition, you may incur the cost of the “spread” – that is, the difference between what investors are willing to pay for Fund shares (the “bid” price) and the price at which they are willing to sell Fund shares (the “ask” price). Because of the costs inherent in buying or selling Fund shares, frequent trading may detract significantly from investment results and an investment in Fund shares may not be advisable for investors who anticipate regularly making small investments.

Materials Sector Risk. Companies in the materials sector could be adversely affected by commodity price volatility, exchange rates, import controls, increased competition, depletion of resources, technical progress, labor relations, exchange rates and government regulations, among other factors. Also, companies in the materials sector are at risk of liability for environmental damage and product liability claims. Production of materials may exceed demand as a result of market imbalances or economic downturns, leading to poor investment returns.

Metals and Mining Sector Risk. The Fund will invest in securities that are issued by and/or have exposure to, companies primarily involved in the metals and mining sector. Investments in metals and mining sector companies may be speculative and subject to greater price volatility than investments in other types of companies. The profitability of companies in the metals and mining sector is related to, among other things, worldwide metal prices, and exploration and production costs. Worldwide metal prices may fluctuate substantially over short periods of time, so the Fund’s share price may be more volatile than other types of investments. In addition, metals and mining companies may be significantly affected by changes in global demand for certain metals, economic developments, energy conservation, exchange rates, the success of exploration projects, interest rates, economic conditions, tax treatment, government regulation and intervention, and world events in the regions that the companies to which the Fund has exposure operate (e.g., expropriation, nationalization, confiscation of assets and property or the imposition of restrictions on foreign investments and repatriation of capital, military coups, social unrest, violence and labor unrest). Metals and mining companies may also be subject to the effects of competitive pressures in the metals and mining sector.

Mid-Capitalization Companies Risk. Many of the companies in which the Fund invests are considered mid-capitalization companies. Stock prices of mid-capitalization companies may be more volatile than those of large-capitalization companies and, therefore, the Fund’s share price may be more volatile than those of funds that invest a

larger percentage of their assets in stocks issued by large-capitalization companies. Stock prices of mid-capitalization companies are also more vulnerable than those of large-capitalization companies to adverse business or economic developments, and the stocks of mid-capitalization companies may be less liquid, making it difficult for the Fund to buy and sell them. In addition, mid-capitalization companies generally have less diverse product lines than large-capitalization companies and are more susceptible to adverse developments related to their products.

Non-Diversification Risk. The Fund is classified as “non-diversified.” This means that the Fund may invest a large percentage of its assets in securities issued by or representing a small number of issuers. As a result, the Fund may be more susceptible to the risks associated with these particular issuers, or to a single economic, political or regulatory occurrence affecting these issuers.

Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers are subject to all of the risks of investing in the markets where such issuers are located, including heightened risks of inflation or nationalization and market fluctuations caused by economic and political developments. As a result of investing in non-U.S. securities, the Fund may be subject to increased risk of loss caused by any of the factors listed below:

  • Lower levels of liquidity and market efficiency;
  • Greater securities price volatility;
  • Exchange rate fluctuations and exchange controls;
  • Less availability of public information about issuers;
  • Limitations on foreign ownership of securities;
  • Imposition of withholding or other taxes;
  • Imposition of restrictions on the expatriation of the funds or other assets of the Fund;
  • Higher transaction and custody costs and delays in settlement procedures;
  • Difficulties in enforcing contractual obligations;
  • Lower levels of regulation of the securities market;
  • Weaker accounting, disclosure and reporting requirements; and
  • Legal principles related to corporate governance, directors’ fiduciary duties and liabilities and stockholders’ rights in markets in which the Fund invests may differ and/or may not be as extensive or protective as those that apply in the United States.

Passive Investment Risk. The Fund is not actively managed and may be affected by a general decline in market segments related to the Underlying Index. The Fund invests in securities included in, or representative of, the Underlying Index regardless of their investment merits. BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

Privatization Risk. Some countries in which the Fund invests have begun a process of privatizing certain entities and industries. In some instances, investors in newly privatized entities have suffered losses due to the inability of the newly privatized

entities to adjust quickly to a competitive environment or changing regulatory and legal standards or, in some cases, due to re-nationalization of such privatized entities. There is no assurance that such losses will not recur.

Reliance on Trading Partners Risk. The economies of many emerging markets countries are dependent on each other and on the United States as key trading partners. Reduction in spending on the products and services of these countries by any of their key trading partners, institution of tariffs or other trade barriers or a slowdown in the economies of any of their key trading partners may cause an adverse impact on the economies of the emerging markets countries in which the Fund invests.


U.S. Trading Partners Risk. The United States is a significant, and in some cases the most significant, trading partner of or foreign investor in the materials sectors of certain emerging markets countries and the economies of these countries may be particularly affected by changes in the U.S. economy. Decreasing U.S. imports, new trade regulations, changes in the U.S. dollar exchange rate or a recession in the United States may have a material adverse effect on the economies of these countries.

Risk of Investing in Brazil. The Fund’s investments in Brazilian issuers may subject the Fund to legal, regulatory, political, currency and economic risks specific to Brazil. Specifically, Brazilian issuers are subject to possible regulatory and economic interventions of the Brazilian government, including the imposition of wage and price controls and limiting imports. In addition, the market for Brazilian securities is directly influenced by the flow of international capital and economic and market conditions of certain countries, especially other emerging market countries in Central and South America.

Risk of Investing in Eastern Europe. Investment in Eastern European issuers may subject the Fund to legal, regulatory, political, currency, security and economic risks specific to Eastern Europe. Economies of certain Eastern European countries rely heavily on export of commodities, including oil and gas and certain metals. As a result, such economies will be negatively impacted by international commodity prices and are particularly vulnerable to global demand for these products. Acts of terrorism in certain Eastern European countries may cause uncertainty in their financial markets and adversely affect the performance of the issuers to which the Fund has exposure. The securities markets in Eastern European countries are substantially smaller and inexperienced, with less government supervision and regulation of stock exchanges and less liquid and more volatile than securities markets in the United States or Western European countries. Economies of Eastern European countries are strongly dependent on the economic health of Western European countries and the European Union as a whole. In addition, investing in securities of Eastern European issuers involves:

  • The risk of delays in settling portfolio transactions and the risk of loss arising out of the system of share registration and custody used in certain Eastern European countries;
  • Risks in connection with the maintenance of the Fund’s portfolio securities and cash with foreign subcustodians and securities depositories, including the risk that appropriate sub-custody arrangements will not be available to the Fund;
  • The risk that the Fund’s ownership rights in portfolio securities could be lost through fraud or negligence as a result of the fact that ownership in shares of certain Eastern European companies is recorded by the companies themselves and by registrars, rather than a central registration system; and
  • The risk that the Fund may not be able to pursue claims on behalf of its shareholders because of the system of share registration and custody, and because certain Eastern European banking institutions and registrars are not guaranteed by the respective governments.

Other risks include: the absence of legal structures governing private and foreign investments and private property; the possibility of the loss of all or a substantial portion of the Fund’s assets invested in Eastern European issuers as a result of expropriation; certain national policies which may restrict the Fund’s investment opportunities, including, without limitation, restrictions on investing in issuers or industries deemed sensitive to relevant national interests.

Securities Lending Risk. The Fund may engage in securities lending. Securities lending involves the risk that the Fund may lose money because the borrower of the Fund’s loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for the loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Security Risk. Some geographic areas in which the Fund invests have experienced acts of terrorism or strained international relations due to territorial disputes, historical animosities or other defense concerns. These situations may cause uncertainty in the markets of these geographic areas and may adversely affect the performance of their economies.

Small-Capitalization Companies Risk. Many of the companies in which the Fund invests are considered small-capitalization companies. Stock prices of small-capitalization companies may be more volatile than those of larger companies and, therefore, the Fund’s share price may be more volatile than those of funds that invest a larger percentage of their assets in stocks issued by mid- or large-capitalization companies. Stock prices of small-capitalization companies are generally more vulnerable than those of mid- or large-capitalization companies to adverse business and economic developments. Securities of small-capitalization companies may be thinly traded, making it difficult for the Fund to buy and sell them. In addition, small-capitalization companies are typically less financially stable than larger, more established companies and may depend on a small number of essential personnel, making them more vulnerable to loss of personnel. Small-capitalization companies also normally have less diverse product lines than mid- or large-capitalization companies and are more susceptible to adverse developments concerning their products.

Structural Risk. Certain political, economic, legal and currency risks have contributed to a high degree of price volatility in the equity markets of emerging markets countries and could adversely affect investments in the Fund:


Political and Social Risk. Disparities of wealth, the pace and success of democratization

and ethnic, religious and racial disaffection, among other factors, have led to social unrest, violence and labor unrest in some emerging markets countries. Unanticipated or sudden political or social developments may result in sudden and significant investment losses.


Economic Risk. Some emerging markets countries may experience economic instability, including instability resulting from substantial rates of inflation or significant devaluations of their currency, or economic recessions causing a negative effect on the economies and securities markets of their economies. Some of these countries may also impose restrictions on the exchange or export of currency or adverse currency exchange rates and may be characterized by a lack of available currency hedging instruments.


Expropriation and/or Nationalization Risk. Investments in certain emerging markets countries may be subject to loss due to expropriation or nationalization of assets and property or the imposition of restrictions on foreign investments and repatriation of capital.


Large Government Debt Risk. Chronic structural public sector deficits in some emerging markets countries may adversely impact investments in the Fund.

Tracking Error Risk. Imperfect correlation between the Fund’s portfolio securities and those in the Underlying Index, rounding of prices, changes to the Underlying Index and regulatory requirements may cause tracking error, which is the divergence of the Fund’s performance from that of the Underlying Index. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Underlying Index does not. Because the Fund employs a representative sampling strategy, the Fund may experience tracking error to a greater extent than a fund that seeks to replicate an index. BFA EXPECTS THAT THE FUND MAY EXPERIENCE HIGHER TRACKING ERROR THAN IS TYPICAL FOR SIMILAR INDEX ETFS.

Valuation Risk. Because non-U.S. exchanges may be open on days when the Fund does not price its shares, the value of the securities in the Fund’s portfolio may change on days when shareholders will not be able to purchase or sell the Fund’s shares. In addition, for purposes of calculating the Fund’s NAV, the value of assets denominated in non-U.S. currencies is converted into U.S. dollars using exchange rates deemed appropriate by BFA. This conversion may result in a difference between the prices used to calculate the Fund’s NAV and the prices used by the Underlying Index, which, in turn, could result in a difference between the Fund’s performance and the performance of the Underlying Index.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

Risk of Investing in Eastern Europe. Investment in Eastern European issuers may subject the Fund to legal, regulatory, political, currency, security and economic risks specific to Eastern Europe. Economies of certain Eastern European countries rely heavily on export of commodities, including oil and gas and certain metals. As a result,

such economies will be negatively impacted by international commodity prices and are particularly vulnerable to global demand for these products. Acts of terrorism in certain Eastern European countries may cause uncertainty in their financial markets and adversely affect the performance of the issuers to which the Fund has exposure. The securities markets in Eastern European countries are substantially smaller and inexperienced, with less government supervision and regulation of stock exchanges and less liquid and more volatile than securities markets in the United States or Western European countries. Economies of Eastern European countries are strongly dependent on the economic health of Western European countries and the European Union as a whole. In addition, investing in securities of Eastern European issuers involves:

  • The risk of delays in settling portfolio transactions and the risk of loss arising out of the system of share registration and custody used in certain Eastern European countries;
  • Risks in connection with the maintenance of the Fund’s portfolio securities and cash with foreign subcustodians and securities depositories, including the risk that appropriate sub-custody arrangements will not be available to the Fund;
  • The risk that the Fund’s ownership rights in portfolio securities could be lost through fraud or negligence as a result of the fact that ownership in shares of certain Eastern European companies is recorded by the companies themselves and by registrars, rather than a central registration system; and
  • The risk that the Fund may not be able to pursue claims on behalf of its shareholders because of the system of share registration and custody, and because certain Eastern European banking institutions and registrars are not guaranteed by the respective governments.

Other risks include: the absence of legal structures governing private and foreign investments and private property; the possibility of the loss of all or a substantial portion of the Fund’s assets invested in Eastern European issuers as a result of expropriation; certain national policies which may restrict the Fund’s investment opportunities, including, without limitation, restrictions on investing in issuers or industries deemed sensitive to relevant national interests.

Sub-Saharan African Economic Risk. The economies of certain sub-Saharan African countries have experienced high unemployment, famine, currency volatility, inflation, general economic malaise, and internal and external conflicts that have resulted in significant displacement of local populations. While countries in the region, such as South Africa, Gabon and Botswana, have experienced greater political stability and economic growth than neighboring states, adverse social and economic conditions in one country may have a significant adverse effect on other countries of this region, including some or all of the emerging markets countries in which the Fund invests.

Management

Investment Adviser. As investment adviser, BFA has overall responsibility for the general management and administration of the Trust. BFA provides an investment program for the Fund and manages the investment of the Fund’s assets. In managing the Fund, BFA may draw upon the research and expertise of its asset management affiliates with respect to certain portfolio securities. In seeking to achieve the Fund’s investment objective, BFA uses teams of portfolio managers, investment strategists and other investment specialists. This team approach brings together many disciplines and leverages BFA’s extensive resources.

Pursuant to the Investment Advisory Agreement between BFA and the Trust (entered into on behalf of the Fund), BFA is responsible for substantially all expenses of the Fund, except interest expenses, taxes, brokerage expenses, future distribution fees or expenses and extraordinary expenses.

For its investment advisory services to the Fund, BFA is entitled to receive a management fee from the Fund corresponding to the Fund’s allocable portion of an aggregate management fee based on the aggregate average daily net assets of the following iShares funds: iShares MSCI All Country Asia ex Japan Index Fund, iShares MSCI BRIC Index Fund, iShares MSCI Emerging Markets Eastern Europe Index Fund, iShares MSCI Emerging Markets Financials Sector Index Fund, iShares MSCI Emerging Markets Index Fund, iShares MSCI Emerging Markets Materials Sector Index Fund, iShares MSCI Emerging Markets Minimum Volatility Index Fund and iShares MSCI Emerging Markets Small Cap Index Fund. The aggregate management fee is calculated as follows: 0.75% per annum of the aggregate net assets less than or equal to $14.0 billion, plus 0.68% per annum of the aggregate net assets over $14.0 billion, up to and including $28.0 billion, plus 0.61% per annum of the aggregate net assets over $28.0 billion, up to and including $42.0 billion, plus 0.56% per annum of the aggregate net assets over $42.0 billion, up to and including $56.0 billion, plus 0.50% per annum of the aggregate net assets over $56.0 billion, up to and including $70.0 billion, plus 0.45% per annum of the aggregate net assets over $70.0 billion, up to and including $84.0 billion, plus 0.40% per annum of the aggregate net assets in excess of $84.0 billion. As calculated on July 31, 2011, for its investment advisory services to the Fund, BFA is entitled to receive a management fee from the Fund, based on a percentage of the Fund’s average daily net assets, at an annual rate of 0.68%.

BFA is located at 400 Howard Street, San Francisco, CA 94105. It is a wholly owned subsidiary of BTC, which in turn is indirectly wholly-owned by BlackRock, Inc. (“BlackRock”). As of September 30, 2011, BTC and its affiliates, including BFA and BlackRock, provided investment advisory services for assets in excess of $3.35 trillion. BFA, BTC, BlackRock Execution Services, BlackRock and their affiliates deal, trade and invest for their own accounts in the types of securities in which the Fund may also invest.

A discussion regarding the basis for the Trust’s Board of Trustees’ (the “Board”) approval of the Investment Advisory Agreement with BFA is available in the Fund’s annual report for the period ended July 31.

Portfolio Managers. Christopher Bliss, Rene Casis, Diane Hsiung and Greg Savage are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager is responsible for various functions related to portfolio management, including, but not limited to, investing cash inflows, coordinating with members of his or her portfolio management team to focus on certain asset classes, implementing investment strategy, researching and reviewing investment strategy and overseeing members of his or her portfolio management team that have more limited responsibilities.

Christopher Bliss has been employed by BFA (formerly, Barclays Global Fund Advisors (“BGFA”)) and BTC (formerly, Barclays Global Investors, N.A. (“BGI”)) as a senior portfolio manager since 2005. Prior to that, Mr. Bliss was a portfolio manager from 2004 to 2005 for BGFA and BGI. Mr. Bliss has been a Portfolio Manager of the Fund since 2011.

Rene Casis has been employed by BFA and BTC as a senior portfolio manager since 2009. From 2005 to 2009, Mr. Casis was a trader at Barclays Capital. Prior to that, Mr. Casis was a portfolio manager from 2000 to 2005 for BGFA and BGI. Mr. Casis has been a Portfolio Manager of the Fund since 2010.

Diane Hsiung has been employed by BFA and BTC as a senior portfolio manager since 2007. Prior to that, Ms. Hsiung was a portfolio manager from 2002 to 2006 for BGFA and BGI. Ms. Hsiung has been a Portfolio Manager of the Fund since inception.

Greg Savage has been employed by BFA and BTC as a senior portfolio manager since 2006. Prior to that, Mr. Savage was a portfolio manager from 2001 to 2006 for BGFA and BGI. Mr. Savage has been a Portfolio Manager of the Fund since inception.

The Fund’s SAI provides additional information about the Portfolio Managers’ compensation, other accounts managed by the Portfolio Managers and the Portfolio Managers’ ownership (if any) of shares in the Fund.

Administrator, Custodian and Transfer Agent. State Street Bank and Trust Company (“State Street”) is the administrator, custodian and transfer agent for the Fund.

Conflicts of Interest. BFA wants you to know that there are certain entities with which BFA has relationships that may give rise to conflicts of interest, or the appearance of conflicts of interest. These entities include the following: BFA’s affiliates (including BlackRock and The PNC Financial Services Group, Inc., and each of their affiliates, directors, partners, trustees, managing members, officers and employees (collectively, the “Affiliates”)) and BlackRock’s significant shareholder, Barclays Bank PLC and its affiliates, including Barclays PLC (each, an “Entity” and together, the “Entities”).

The activities of BFA, the Affiliates and the Entities in the management of, or their interest in, their own accounts and other accounts they manage, may present conflicts of interest that could disadvantage the Fund and its shareholders. BFA and its Affiliates

or the Entities provide investment management services to other funds and discretionary managed accounts that may follow an investment program similar to that of the Fund. BFA, its Affiliates and the Entities are involved worldwide with a broad spectrum of financial services and asset management activities and may engage in the ordinary course of business in activities in which their interests or the interests of their clients may conflict with those of the Fund. BFA, one or more of the Affiliates or the Entities acts, or may act, as an investor, investment banker, research provider, investment manager, financier, underwriter, advisor, market maker, trader, prime broker, lender, agent or principal, and have other direct and indirect interests, in securities, currencies and other instruments in which the Fund may directly or indirectly invest. Thus, it is likely that the Fund will have multiple business relationships with and will invest in, engage in transactions with, make voting decisions with respect to, or obtain services from, entities for which BFA, an Affiliate or an Entity performs or seeks to perform investment banking or other services.

BFA or one or more Affiliates or Entities may engage in proprietary trading and advise accounts and funds that have investment objectives similar to those of the Fund and/or that engage in and compete for transactions in the same types of securities, currencies and other instruments as the Fund, including in securities issued by other open-end and closed-end investment management companies, including investment companies that are affiliated with the Fund and BFA, to the extent permitted under the Investment Company Act of 1940, as amended (the “1940 Act”). The trading activities of BFA, these Affiliates and Entities are carried out without reference to positions held directly or indirectly by the Fund and may result in BFA, an Affiliate or an Entity having positions that are adverse to those of the Fund.

No Affiliate or Entity is under any obligation to share any investment opportunity, idea or strategy with the Fund. As a result, an Affiliate or an Entity may compete with the Fund for appropriate investment opportunities. As a result of this and several other factors, the results of the Fund’s investment activities may differ from those of an Affiliate or an Entity and of other accounts managed by an Affiliate or an Entity, and it is possible that the Fund could sustain losses during periods in which one or more Affiliates or Entities and other accounts achieve profits on their trading for proprietary or other accounts. The opposite result is also possible.

The Fund may, from time to time, enter into transactions in which BFA or an Affiliate’s or an Entity’s clients have an interest adverse to the Fund. Furthermore, transactions undertaken by Affiliate-advised clients may adversely impact the Fund. Transactions by one or more Affiliate- or Entity-advised clients or BFA may have the effect of diluting or otherwise disadvantaging the values, prices or investment strategies of the Fund.

An Entity may maintain securities indices as part of its product offerings. Index-based funds seek to track the performance of securities indices and may use the name of the index in the fund name. Index providers, including the Entities, may be paid licensing fees for use of their indices or index names. Entities will not be obligated to license their indices to BFA and its Affiliates, and BFA and its Affiliates will not be assured that the terms of any index licensing agreement with the Entities will be as favorable as those terms offered to other index licensees.

The Fund’s activities may be limited because of regulatory restrictions applicable to one or more Affiliates or Entities, and/or their internal policies designed to comply with such restrictions. In addition, the Fund may invest in securities of companies with which an Affiliate or an Entity has or is trying to develop investment banking relationships or in which an Affiliate or an Entity has significant debt or equity investments. The Fund also may invest in securities of companies for which an Affiliate or an Entity provides or may some day provide research coverage. An Affiliate or an Entity may have business relationships with and purchase or distribute or sell services or products from or to distributors, consultants or others who recommend the Fund or who engage in transactions with or for the Fund, and may receive compensation for such services. The Fund may also make brokerage and other payments to Affiliates or Entities in connection with the Fund’s portfolio investment transactions.

Pursuant to a securities lending program approved by the Board, the Fund has retained an Affiliate of BFA to serve as the securities lending agent for the Fund to the extent that the Fund participates in the securities lending program. For these services, the lending agent may receive a fee from the Fund, including a fee based on the returns earned on the Fund’s investment of the cash received as collateral for any loaned securities. In addition, one or more Affiliates may be among the entities to which the Fund may lend its portfolio securities under the securities lending program.

The activities of BFA, the Affiliates or Entities may give rise to other conflicts of interest that could disadvantage the Fund and its shareholders. BFA has adopted policies and procedures designed to address these potential conflicts of interest. See the Fund’s SAI for further information.

Shareholder Information

Additional shareholder information, including how to buy and sell shares of the Fund, is available free of charge by calling toll-free: 1-800-iShares (1-800-474-2737) or visiting our website at www.iShares.com.

Buying and Selling Shares. Shares of the Fund may be acquired or redeemed directly from the Fund only in Creation Units or multiples thereof, as discussed in the Creations and Redemptions section of this Prospectus. Only an Authorized Participant (as defined in the Creations and Redemptions section) may engage in creation or redemption transactions directly with the Fund. Once created, shares of the Fund generally trade in the secondary market in amounts less than a Creation Unit.

Shares of the Fund are listed on a national securities exchange for trading during the trading day. Shares can be bought and sold throughout the trading day like shares of other publicly-traded companies. The Trust does not impose any minimum investment for shares of the Fund purchased on an exchange. The Fund’s shares trade under the trading symbol “EMMT.”

Buying or selling Fund shares on an exchange involves two types of costs that may apply to all securities transactions. When buying or selling shares of the Fund through a broker, you will likely incur a brokerage commission or other charges determined by your broker. The commission is frequently a fixed amount and may be a significant proportional cost for investors seeking to buy or sell small amounts of shares. In

addition, you may incur the cost of the “spread” – that is, any difference between the bid price and the ask price. The spread varies over time for shares of the Fund based on its trading volume and market liquidity, and is generally lower if the Fund has a lot of trading volume and market liquidity, and higher if the Fund has little trading volume and market liquidity.

The Board has adopted a policy of not monitoring for frequent purchases and redemptions of Fund shares (“frequent trading”) that appear to attempt to take advantage of a potential arbitrage opportunity presented by a lag between a change in the value of the Fund’s portfolio securities after the close of the primary markets for the Fund’s portfolio securities and the reflection of that change in the Fund’s NAV (“market timing”), because the Fund generally sells and redeems its shares directly through transactions that are in-kind and/or for cash, subject to the conditions described below under Creations and Redemptions. The Board has not adopted a policy of monitoring for other frequent trading activity because shares of the Fund are listed for trading on a national securities exchange.

The national securities exchange on which the Fund’s shares are listed is open for trading Monday through Friday and is closed on weekends and the following holidays: New Year’s Day, Martin Luther King, Jr. Day, Presidents’ Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day. The Fund’s primary listing exchange is NASDAQ.

Section 12(d)(1) of the 1940 Act restricts investments by investment companies in the securities of other investment companies. Registered investment companies are permitted to invest in the Fund beyond the limits set forth in Section 12(d)(1), subject to certain terms and conditions set forth in SEC rules or in an SEC exemptive order issued to the Trust. In order for a registered investment company to invest in shares of the Fund beyond the limitations of Section 12(d)(1) pursuant to the exemptive relief obtained by the Trust, the registered investment company must enter into an agreement with the Trust.

Book Entry. Shares of the Fund are held in book-entry form, which means that no stock certificates are issued. The Depository Trust Company (“DTC”) or its nominee is the record owner of all outstanding shares of the Fund and is recognized as the owner of all shares for all purposes.

Investors owning shares of the Fund are beneficial owners as shown on the records of DTC or its participants. DTC serves as the securities depository for shares of the Fund. DTC participants include securities brokers and dealers, banks, trust companies, clearing corporations and other institutions that directly or indirectly maintain a custodial relationship with DTC. As a beneficial owner of shares, you are not entitled to receive physical delivery of stock certificates or to have shares registered in your name, and you are not considered a registered owner of shares. Therefore, to exercise any right as an owner of shares, you must rely upon the procedures of DTC and its participants. These procedures are the same as those that apply to any other securities that you hold in book-entry or “street name” form.

Share Prices. The trading prices of the Fund’s shares in the secondary market generally differ from the Fund’s daily NAV and are affected by market forces such as

supply and demand, economic conditions and other factors. Information regarding the intraday value of shares of the Fund, also known as the “indicative optimized portfolio value” (“IOPV”), is disseminated every 15 seconds throughout the trading day by the national securities exchange on which the Fund’s shares are listed or by market data vendors or other information providers. The IOPV is based on the current market value of the securities and/or cash required to be deposited in exchange for a Creation Unit. The IOPV does not necessarily reflect the precise composition of the current portfolio of securities held by the Fund at a particular point in time or the best possible valuation of the current portfolio. Therefore, the IOPV should not be viewed as a “real-time” update of the Fund’s NAV, which is computed only once a day. The IOPV is generally determined by using both current market quotations and/or price quotations obtained from broker-dealers that may trade in the portfolio securities held by the Fund. The quotations of certain Fund holdings may not be updated during U.S. trading hours if such holdings do not trade in the United States. The Fund is not involved in, or responsible for, the calculation or dissemination of the IOPV and makes no representation or warranty as to its accuracy.

Determination of Net Asset Value. The NAV of the Fund normally is determined once daily Monday through Friday, generally as of the regularly scheduled close of business of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m., Eastern time) on each day that the NYSE is open for trading, based on prices at the time of closing provided that (a) any Fund assets or liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers (as detailed below) and (b) U.S. fixed income assets may be valued as of the announced closing time for trading in fixed income instruments in a particular market or exchange. The NAV of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets held by the Fund, and its liabilities, are determined pursuant to valuation policies and procedures approved by the Board. The Fund’s assets and liabilities are valued primarily on the basis of market quotations.

Equity investments are valued at market value, which is generally determined using the last reported official closing price or last trading price on the exchange or market on which the security is primarily traded at the time of valuation.

The Fund invests in foreign securities. Foreign currency exchange rates are generally determined as of 4:00 p.m., London time. Foreign securities owned by the Fund may trade on weekends or other days when the Fund does not price its shares. As a result, the Fund’s NAV may change on days when Authorized Participants will not be able to purchase or redeem Fund shares.

Generally, trading in foreign securities, U.S. government securities, money market instruments and certain fixed-income securities is substantially completed each day at various times prior to the close of business on the NYSE. The values of such securities used in computing the NAV of the Fund are determined as of such times.

When market quotations are not readily available or are believed by BFA to be unreliable, the Fund’s investments are valued at fair value. Fair value determinations are made by BFA in accordance with policies and procedures approved by the Fund’s Board. BFA may conclude that a market quotation is not readily available or is unreliable if a security or other asset or liability does not have a price source due to its lack of liquidity, if a market quotation differs significantly from recent price quotations or otherwise no longer appears to reflect fair value, where the security or other asset or liability is thinly traded, or where there is a significant event subsequent to the most recent market quotation. A “significant event” is an event that, in the judgment of BFA, is likely to cause a material change to the closing market price of the asset or liability held by the Fund. Foreign securities whose values are affected by volatility that occurs in U.S. markets on a trading day after the close of foreign securities markets may be fair valued.

Fair value represents a good faith approximation of the value of an asset or liability. The fair value of an asset or liability held by the Fund is the amount the Fund might reasonably expect to receive from the current sale of that asset or the cost to extinguish that liability in an arm’s-length transaction. Valuing the Fund’s investments using fair value pricing will result in prices that may differ from current market valuations and that may not be the price at which those investments could have been sold during the period in which the particular fair values were used. Use of fair value prices and certain current market valuations could result in a difference between the prices used to calculate the Fund’s NAV and the prices used by the Underlying Index, which, in turn, could result in a difference between the Fund’s performance and the performance of the Underlying Index.

The value of assets or liabilities denominated in non-U.S. currencies will be converted into U.S. dollars using exchange rates deemed appropriate by BFA as investment adviser. Use of a rate different from the rate used by the Index Provider may adversely affect the Fund’s ability to track the Underlying Index.

Dividends and Distributions

General Policies. Dividends from net investment income, if any, generally are declared and paid semi-annually by the Fund. Distributions of net realized securities gains, if any, generally are declared and paid once a year, but the Trust may make distributions on a more frequent basis for the Fund. The Trust reserves the right to declare special distributions if, in its reasonable discretion, such action is necessary or advisable to preserve its status as a regulated investment company (“RIC”) or to avoid imposition of income or excise taxes on undistributed income or realized gains.

Dividends and other distributions on shares of the Fund are distributed on a pro rata basis to beneficial owners of such shares. Dividend payments are made through DTC participants and indirect participants to beneficial owners then of record with proceeds received from the Fund.

Dividend Reinvestment Service. No dividend reinvestment service is provided by the Trust. Broker-dealers may make available the DTC book-entry Dividend Reinvestment Service for use by beneficial owners of the Fund for reinvestment of their dividend distributions. Beneficial owners should contact their broker to determine the

availability and costs of the service and the details of participation therein. Brokers may require beneficial owners to adhere to specific procedures and timetables. If this service is available and used, dividend distributions of both income and realized gains will be automatically reinvested in additional whole shares of the Fund purchased in the secondary market.

Taxes. As with any investment, you should consider how your investment in shares of the Fund will be taxed. The tax information in this Prospectus is provided as general information, based on current law. You should consult your own tax professional about the tax consequences of an investment in shares of the Fund.

Unless your investment in Fund shares is made through a tax-exempt entity or tax-deferred retirement account, such as an IRA, you need to be aware of the possible tax consequences when the Fund makes distributions or you sell Fund shares.

Taxes on Distributions. Distributions from the Fund’s net investment income (other than qualified dividend income), including distributions of income from securities lending and distributions out of the Fund’s net short-term capital gains, if any, are taxable to you as ordinary income. Distributions by the Fund of net long-term capital gains in excess of net short-term capital losses (capital gain dividends) are taxable to you as long-term capital gains, generally at a 15% tax rate (0% at certain income levels), regardless of how long you have held the Fund’s shares. Distributions by the Fund that qualify as qualified dividend income are taxable to you at long-term capital gain rates for taxable years beginning on or before December 31, 2012. The 15% and 0% tax rates expire for taxable years beginning after December 31, 2012. Maximum long-term capital gain income tax rates are scheduled to rise to 20% in 2013. Beginning in 2013, a 3.8% U.S. federal Medicare contribution tax will be imposed on “net investment income,” including interest, dividends, and capital gains, of U.S. individuals with income exceeding $200,000 (or $250,000 if married and filing jointly), and of estates and trusts.

Dividends will be qualified dividend income to you if they are attributable to qualified dividend income received by the Fund. Generally, qualified dividend income includes dividend income from taxable U.S. corporations and qualified non-U.S. corporations, provided that the Fund satisfies certain holding period requirements in respect of the stock of such corporations and has not hedged its position in the stock in certain ways. Substitute dividends received by the Fund with respect to dividends paid on securities lent out will not be qualified dividend income. For this purpose, a qualified non-U.S. corporation means any non-U.S. corporation that is eligible for benefits under a comprehensive income tax treaty with the United States, which includes an exchange of information program or if the stock with respect to which the dividend was paid is readily tradable on an established United States securities market. The term excludes a corporation that is a passive foreign investment company.

Dividends received by the Fund from a real estate investment trust (“REIT”) or another RIC generally are qualified dividend income only to the extent the dividend distributions are made out of qualified dividend income received by such REIT or RIC. It is expected that dividends received by the Fund from a REIT and distributed to a shareholder generally will be taxable to the shareholder as ordinary income.

For a dividend to be treated as qualified dividend income, the dividend must be received with respect to a share of stock held without being hedged by the Fund, and with respect to a share of the Fund held without being hedged by you, for 61 days during the 121-day period beginning at the date which is 60 days before the date on which such share becomes ex-dividend with respect to such dividend or, in the case of certain preferred stock, 91 days during the 181-day period beginning 90 days before such date.

If your Fund shares are loaned out pursuant to a securities lending arrangement, you may lose the ability to use foreign tax credits passed through by the Fund or to treat Fund dividends paid while the shares are held by the borrower as qualified dividend income.

In general, your distributions are subject to U.S. federal income tax for the year when they are paid. Certain distributions paid in January, however, may be treated as paid on December 31 of the prior year.

If the Fund’s distributions exceed current and accumulated earnings and profits, all or a portion of the distributions made in the taxable year may be recharacterized as a return of capital to shareholders. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and result in a higher capital gain or lower capital loss when those shares on which the distribution was received are sold. Once a shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain, if the shareholder holds shares of the Fund as capital assets.

If you are neither a resident nor a citizen of the United States or if you are a non-U.S. entity, the Fund’s ordinary income dividends (which include distributions of net short-term capital gains) will generally be subject to a 30% U.S. withholding tax, unless a lower treaty rate applies, provided that withholding tax will generally not apply to any gain or income realized by a non-U.S. shareholder in respect of any distributions of long-term capital gains or upon the sale or other disposition of shares of the Fund.

A 30% withholding tax will be imposed on dividends paid after December 31, 2013, and redemption proceeds paid after December 31, 2014, to (i) foreign financial institutions including non-U.S. investment funds unless they agree to collect and disclose to the Internal Revenue Service (“IRS”) information regarding their direct and indirect U.S. account holders and (ii) certain other foreign entities, unless they certify certain information regarding their direct and indirect U.S. owners. To avoid withholding, foreign financial institutions will need to enter into agreements with the IRS that state that they will provide the IRS information, including the name, address and taxpayer identification number of direct and indirect U.S. account holders, comply with due diligence procedures with respect to the identification of U.S. accounts, report to the IRS certain information with respect to U.S. accounts maintained, agree to withhold tax on certain payments made to non-compliant foreign financial institutions or to account holders who fail to provide the required information, and determine certain other information as to their account holders. Other foreign entities will need to provide the name, address, and taxpayer identification number of each substantial U.S. owner or certifications of no substantial U.S. ownership unless certain exceptions apply.

Dividends, interest and capital gains earned by the Fund with respect to non-U.S. securities may give rise to withholding and other taxes imposed by non-U.S. countries. Tax conventions between certain countries and the United States may reduce or eliminate such taxes. If more than 50% of the total assets of the Fund at the close of a year consists of non-U.S. stocks or securities, the Fund may “pass through” to you certain non-U.S. income taxes (including withholding taxes) paid by the Fund. This means that you would be considered to have received as an additional dividend your share of such non-U.S. taxes, but you may be entitled to either a corresponding tax deduction in calculating your taxable income, or, subject to certain limitations, a credit in calculating your U.S. federal income tax.

For purposes of foreign tax credits for U.S. shareholders of the Fund, foreign capital gains taxes may not produce associated foreign source income, thereby limiting a U.S. person’s ability to use such credits.

If you are a resident or a citizen of the United States, by law, back-up withholding will apply to your distributions and proceeds if you have not provided a taxpayer identification number or social security number and made other required certifications.

Taxes When Shares are Sold. Currently, any capital gain or loss realized upon a sale of Fund shares is generally treated as a long-term gain or loss if the shares have been held for more than one year. Any capital gain or loss realized upon a sale of Fund shares held for one year or less is generally treated as short-term gain or loss, except that any capital loss on the sale of shares held for six months or less is treated as long-term capital loss to the extent that capital gain dividends were paid with respect to such shares. Beginning in 2013, any such capital gains, including from sales of Fund shares or from capital gain dividends, will be included in “net investment income” for purposes of the 3.8% U.S. federal Medicare contribution tax mentioned above.

The foregoing discussion summarizes some of the consequences under current U.S. federal tax law of an investment in the Fund. It is not a substitute for personal tax advice. You may also be subject to state and local taxation on Fund distributions and sales of shares. Consult your personal tax adviser about the potential tax consequences of an investment in shares of the Fund under all applicable tax laws.

Creations and Redemptions. Prior to trading in the secondary market, shares of the Fund are “created” at NAV by market makers, large investors and institutions only in block-size Creation Units of 50,000 shares or multiples thereof. Each “creator” or “Authorized Participant” enters into an authorized participant agreement with the Fund’s distributor, SEI Investments Distribution Co. (the “Distributor”). Only an Authorized Participant may create or redeem Creation Units directly with the Fund. A creation transaction, which is subject to acceptance by the transfer agent, generally takes place when an Authorized Participant deposits into the Fund a designated portfolio of securities and a specified amount of cash approximating the holdings of the Fund in exchange for a specified number of Creation Units. To the extent practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund.

Similarly, shares can be redeemed only in Creation Units, generally for a designated portfolio of securities and a specified amount of cash held by the Fund (“Fund

Securities”). Except when aggregated in Creation Units, shares are not redeemable by the Fund. The prices at which creations and redemptions occur are based on the next calculation of NAV after an order is received in a form described in the authorized participant agreement.

The Fund intends to comply with the U.S. federal securities laws in accepting securities for deposit and satisfying redemptions with redemption securities by, among other means, assuring that any securities accepted for deposit and any securities used to satisfy redemption requests will be sold in transactions that would be exempt from registration under the Securities Act of 1933, as amended (the “1933 Act”). Further, an Authorized Participant that is not a “qualified institutional buyer,” as such term is defined under Rule 144A of the 1933 Act, will not be able to receive Fund Securities that are restricted securities eligible for resale under Rule 144A.

Creations and redemptions must be made through a firm that is either a member of the Continuous Net Settlement System of the National Securities Clearing Corporation or a DTC participant and has executed an agreement with the Distributor with respect to creations and redemptions of Creation Unit aggregations. Information about the procedures regarding creation and redemption of Creation Units (including the cut-off times for receipt of creation and redemption orders) is included in the Fund’s SAI.

Because new shares may be created and issued on an ongoing basis, at any point during the life of the Fund a “distribution,” as such term is used in the 1933 Act, may be occurring. Broker-dealers and other persons are cautioned that some activities on their part may, depending on the circumstances, result in their being deemed participants in a distribution in a manner that could render them statutory underwriters and subject to the prospectus delivery and liability provisions of the 1933 Act. Any determination of whether one is an underwriter must take into account all the relevant facts and circumstances of each particular case.

Broker-dealers should also note that dealers who are not “underwriters” but are participating in a distribution (as contrasted to ordinary secondary transactions), and thus dealing with shares that are part of an “unsold allotment” within the meaning of Section 4(3)(C) of the 1933 Act, would be unable to take advantage of the prospectus delivery exemption provided by Section 4(3) of the 1933 Act. For delivery of prospectuses to exchange members, the prospectus delivery mechanism of Rule 153 under the 1933 Act is available only with respect to transactions on a national securities exchange.

Costs Associated with Creations and Redemptions. Authorized Participants are charged standard creation and redemption transaction fees to offset transfer and other transaction costs associated with the issuance and redemption of Creation Units. The standard creation and redemption transaction fees are set forth in the table below. The standard creation transaction fee is charged to the Authorized Participant on the day such Authorized Participant creates a Creation Unit, and is the same regardless of the number of Creation Units purchased by the Authorized Participant on the applicable business day. Similarly, the standard redemption transaction fee is charged to the Authorized Participant on the day such Authorized Participant redeems a Creation Unit, and is the same regardless of the number of Creation Units redeemed by the Authorized Participant on the applicable business day. Creations and

redemptions for cash (when cash creations and redemptions (in whole or in part) are available or specified) are also subject to an additional charge (up to the maximum amounts shown in the table below). This charge is intended to compensate for brokerage, tax, foreign exchange, execution, market impact and other costs and expenses related to cash transactions. Investors who use the services of a broker or other financial intermediary may pay fees for such services.

The following table shows, as of September 30, 2011, the approximate value of one Creation Unit, standard fees and maximum additional charges for creations and redemptions (as described above):

Householding. Householding is an option available to certain Fund investors. Householding is a method of delivery, based on the preference of the individual investor, in which a single copy of certain shareholder documents can be delivered to investors who share the same address, even if their accounts are registered under different names. Please contact your broker-dealer if you are interested in enrolling in householding and receiving a single copy of prospectuses and other shareholder documents, or if you are currently enrolled in householding and wish to change your householding status.

Distribution

The Distributor distributes Creation Units for the Fund on an agency basis. The Distributor does not maintain a secondary market in shares of the Fund. The Distributor has no role in determining the policies of the Fund or the securities that are purchased or sold by the Fund. The Distributor’s principal address is One Freedom Valley Drive, Oaks, PA 19456.

In addition, BFA or its Affiliates make payments to broker-dealers, banks or other financial intermediaries (together, “intermediaries”) related to marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems, or their making shares of the Fund and certain other iShares funds available to their customers. Such payments, which may be significant to the intermediary, are not made by the Fund. Rather, such payments are made by BFA or its Affiliates from their own resources, which come directly or indirectly in part from fees paid by the iShares funds complex. Payments of this type are sometimes referred to as revenue-sharing payments. A financial intermediary may make decisions about which investment options it recommends or makes available, or the level of services provided, to its customers based on the revenue-sharing payments it is eligible to receive. Therefore, such payments to an intermediary create

conflicts of interest between the intermediary and its customers and may cause the intermediary to recommend the Fund or other iShares funds over another investment. More information regarding these payments is contained in the Fund’s SAI. Please contact your salesperson or other investment professional for more information regarding any such payments his or her firm may receive from BFA or its Affiliates.

Financial Highlights

The financial highlights table is intended to help investors understand the Fund’s financial performance since inception. Certain information reflects financial results for a single share of the Fund. The total returns in the table represent the rate that an investor would have earned (or lost) on an investment in the Fund, assuming reinvestment of all dividends and distributions. This information has been audited by PricewaterhouseCoopers LLP, whose report is included, along with the Fund’s financial statements, in the Fund’s Annual Report (available upon request).

Supplemental Information

I. Premium/Discount Information

The table that follows presents information about the differences between the daily market price on secondary markets for shares of the Fund and the Fund’s NAV. NAV is the price at which the Fund issues and redeems shares. It is calculated in accordance with the standard formula for valuing mutual fund shares. The price used to calculate market returns (“Market Price”) of the Fund generally is determined using the midpoint between the highest bid and the lowest offer on the primary securities exchange on which shares of the Fund are listed for trading, as of the time that the Fund’s NAV is calculated. The Fund’s Market Price may be at, above or below its NAV. The NAV of the Fund will fluctuate with changes in the value of its portfolio holdings. The Market Price of the Fund will fluctuate in accordance with changes in its NAV, as well as market supply and demand.

Premiums or discounts are the differences (expressed as a percentage) between the NAV and Market Price of the Fund on a given day, generally at the time the NAV is calculated. A premium is the amount that the Fund is trading above the reported NAV, expressed as a percentage of the NAV. A discount is the amount that the Fund is trading below the reported NAV, expressed as a percentage of the NAV.

The following information shows the frequency of distributions of premiums and discounts for the Fund from April 1, 2010 through September 30, 2011.

Each line in the table shows the number of trading days in which the Fund traded within the premium/discount range indicated. The number of trading days in each premium/discount range is also shown as a percentage of the total number of trading days in the period covered by the table. All data presented here represents past performance, which cannot be used to predict future results.

Premium/Discount Range

Greater than 1.5% and Less than 2.0% 1 0.26%
Greater than 1.0% and Less than 1.5% 3 0.79

Less than -2.0% 1 0.26
   380 100.00%

II. Total Return Information

The table that follows presents information about the total returns of the Fund and the Underlying Index as of the fiscal year ended July 31, 2011.

“Average Annual Total Returns” represent the average annual change in value of an investment over the periods indicated. “Cumulative Total Returns” represent the total change in value of an investment over the period indicated.

The Fund’s NAV is the value of one share of the Fund as calculated in accordance with the standard formula for valuing mutual fund shares. The NAV return is based on the NAV of the Fund and the market return is based on the Market Price of the Fund. Market Price is determined by using the midpoint between the highest bid and the lowest offer on the primary stock exchange on which shares of the Fund are listed for trading, as of the time that the Fund’s NAV is calculated. Since shares of the Fund did not trade in the secondary market until after the Fund’s inception, for the period from inception to the first day of secondary market trading in shares of the Fund, the NAV of the Fund is used as a proxy for the Market Price to calculate market returns. Market and NAV returns assume that dividends and capital gain distributions have been reinvested in the Fund at Market Price and NAV, respectively.

An index is a statistical composite that tracks a specified financial market or sector. Unlike the Fund, the Underlying Index does not actually hold a portfolio of securities and therefore does not incur the expenses incurred by the Fund. These expenses negatively impact the performance of the Fund. Also, market returns do not include brokerage commissions that may be payable on secondary market transactions. If brokerage commissions were included, market returns would be lower. The returns shown in the following table do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption or sale of Fund shares. The investment return and principal value of shares of the Fund will vary with changes in market conditions. Shares of the Fund may be worth more or less than their original cost when they are redeemed or sold in the market. The Fund’s past performance is no guarantee of future results.

Fund Overview

iSHARES® MSCI EUROPE FINANCIALS SECTOR INDEX FUND

Ticker: EUFN Stock Exchange: NASDAQ

Investment Objective

The iShares MSCI Europe Financials Sector Index Fund (the “Fund”) seeks investment results that correspond generally to the price and yield performance, before fees and expenses, of the MSCI Europe Financials Index (the “Underlying Index”).

Fees and Expenses

The following table describes the fees and expenses that you will incur if you own shares of the Fund. The investment advisory agreement between iShares Trust (the “Trust”) and BlackRock Fund Advisors (“BFA”) (the “Investment Advisory Agreement”) provides that BFA will pay all operating expenses of the Fund, except interest expenses, taxes, brokerage expenses, future distribution fees or expenses, and extraordinary expenses.

You may also incur usual and customary brokerage commissions when buying or selling shares of the Fund, which are not reflected in the example that follows:

Example. This Example is intended to help you compare the cost of owning shares of the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

3 Years
5 Years
10 Years

Portfolio Turnover. The Fund may pay transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 10% of the average value of its portfolio.

Principal Investment Strategies

The Underlying Index is a free float-adjusted market capitalization-weighted index designed to measure the combined equity market performance of the financial sector of developed market countries in Europe. Component securities include those of banks, diversified financial companies, insurance companies and real estate companies. As of September 30, 2011, the Underlying Index consisted of companies in the following countries: Austria, Belgium, Denmark, Finland, France, Germany, Greece, Italy, the Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom (together, the “Europe financial sector countries”). As of September 30, 2011, the Underlying Index was comprised of 102 securities.

BFA uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to “beat” the index it tracks and does not seek temporary defensive positions when markets decline or appear overvalued.

Indexing may eliminate the chance that the Fund will substantially outperform the Underlying Index but also may reduce some of the risks of active management, such as poor security selection. Indexing seeks to achieve lower costs and better after-tax performance by keeping portfolio turnover low in comparison to actively managed investment companies.

BFA uses a representative sampling indexing strategy to manage the Fund. “Representative sampling” is an indexing strategy that involves investing in a representative sample of securities that collectively has an investment profile similar to the Underlying Index. The securities selected are expected to have, in the aggregate, investment characteristics (based on factors such as market capitalization and industry weightings), fundamental characteristics (such as return variability and yield) and liquidity measures similar to those of the Underlying Index. The Fund may or may not hold all of the securities in the Underlying Index.

The Fund generally invests at least 80% of its assets in securities of the Underlying Index and in depositary receipts representing securities of the Underlying Index. The Fund may invest the remainder of its assets in securities not included in the Underlying Index, but which BFA believes will help the Fund track the Underlying Index and in other investments including futures contracts, options on futures contracts, options and swaps as well as cash and cash equivalents, including shares of money market funds advised by BFA or its affiliates.

The Fund may lend securities representing up to one-third of the

S-2   


Table Of Contents



value of the Fund’s total assets (including the value of the collateral received).

The Underlying Index is sponsored by an organization (the “Index Provider”) that is independent of the Fund and BFA. The Index Provider determines the composition and relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index. The Fund’s Index Provider is MSCI Inc. (“MSCI”).

Industry Concentration Policy. The Fund will concentrate its investments (i.e., hold 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. For purposes of this limitation, securities of the U.S. government (including its agencies and instrumentalities) and repurchase agreements collateralized by U.S. government securities are not considered to be issued by members of any industry.

Summary of Principal Risks

As with any investment, you could lose all or part of your investment in the Fund, and the Fund’s performance could trail that of other investments. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund’s net asset value per share (“NAV”), trading price, yield, total return and ability to meet its investment objective.

Asset Class Risk. Securities in the Underlying Index or in the Fund’s portfolio may underperform in comparison to the general securities markets or other asset classes.

Concentration Risk. To the extent that the Fund’s investments are concentrated in a particular issuer, region, country, market, industry or asset class, the Fund may be susceptible to loss due to adverse occurrences affecting that issuer, region, country, market, industry or asset class.

Currency Risk. Because the Fund’s NAV is determined in U.S. dollars, the Fund’s NAV could decline if the currency of a non-U.S. market in which the Fund invests depreciates against the U.S. dollar.

Equity Securities Risk. Equity securities are subject to changes in value and their values may be more volatile than other asset classes.

Financial Sector Risk. Performance of companies in the financial sector may be adversely impacted by many factors, including, among others, government regulations, economic conditions, credit rating downgrades, changes in interest rates, and decreased liquidity in credit markets. This sector has experienced significant losses in the recent past, and the impact of more stringent capital requirements and of recent or future regulation on any individual financial company or on the sector as a whole cannot be predicted.

Geographic Risk. A natural or other disaster could occur in a geographic region in which the Fund invests, which could affect the economy or particular business operations of companies in the specific geographic region, causing an adverse impact on the Fund’s investments in the affected region.

Insurance Industry Risk. The insurance industry may be significantly affected by changes in interest rates, catastrophic events, price and

S-3

marketing competition, the imposition of premium rate caps, or other changes in government regulation or tax law, among other factors.

Issuer Risk. Fund performance depends on the performance of individual securities to which the Fund has exposure. Changes to the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA’s investment management strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares, losses from trading in secondary markets, periods of high volatility and disruption in the creation/redemption process of the Fund. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV.

Mid-Capitalization Companies Risk. The Fund may invest in the securities of mid-capitalization companies. Compared to large-capitalization companies, mid-capitalization companies may be less stable and more susceptible to adverse developments and their securities may be more volatile and less liquid.

Non-Diversification Risk. The Fund may invest a large percentage of its assets in securities issued by or representing a small number of issuers. As a result, the Fund’s performance may depend on the performance of a small number of issuers.

Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers are subject to the risks associated with investing in those non-U.S. markets, such as heightened risks of inflation or nationalization. The Fund may lose money due to political, economic and geographic events affecting a non-U.S. issuer or market. The Fund is specifically exposed to European Economic Risk.

Passive Investment Risk. The Fund is not actively managed and BFA does not attempt to take defensive positions under any market conditions, including declining markets.

Privatization Risk. Some countries in which the Fund invests have begun a process of privatizing certain entities and industries. Privatized entities may lose money or be re-nationalized.

Reliance on Trading Partners Risk. The Fund invests in countries whose economies are heavily dependent upon trading with key partners. Any reduction in this trading may have an adverse impact on the Fund’s investments. Through its trading partners, the Fund is particularly exposed to U.S. Trading Partner Risk.

Risk of Investing in the United Kingdom. The Fund’s investment in British issuers may subject the Fund to regulatory, political, currency, security, and economic risk specific to the United Kingdom. The United Kingdom has one of the largest economies in Europe, and the United States and other European countries are substantial trading partners of the United Kingdom. As a result, the British economy may be

Table Of Contents



impacted by changes to the economic health of the United States and other European countries. The British economy, along with certain other European economies, experienced a significant economic slowdown during the recent financial crisis; certain British financial institutions were severely under-capitalized and required government intervention to survive.

Securities Lending Risk. The Fund may engage in securities lending. Securities lending involves the risk that the Fund may lose money because the borrower of the Fund’s loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Small-Capitalization Companies Risk. The Fund invests in the securities of small-capitalization companies. Compared to mid- and large-capitalization companies, small-capitalization companies may be less stable and more susceptible to adverse developments and their securities may be more volatile and less liquid.

Structural Risk. The countries in which the Fund invests may be subject to considerable degrees of economic, political and social instability.

Tracking Error Risk. The performance of the Fund may diverge from that of the Underlying Index. Because the Fund employs a representative sampling strategy, the Fund may experience tracking error to a greater extent than a fund that seeks to replicate an index.

Valuation Risk. The value of the securities in the Fund’s portfolio may change on days when shareholders will not be able to purchase or sell the Fund’s shares.

Performance Information

As of the date of the Fund’s prospectus (the “Prospectus”), the Fund has been in operation for less than one full calendar year and therefore does not report its performance information.

Management

Investment Adviser. BlackRock Fund Advisors.

Portfolio Managers. Rene Casis, Diane Hsiung and Greg Savage (the “Portfolio Managers”) are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager supervises a portfolio management team. Mr. Casis has been a Portfolio Manager of the Fund since 2010. Ms. Hsiung and Mr. Savage have been Portfolio Managers of the Fund since inception.

Purchase and Sale of Fund Shares

The Fund is an exchange-traded fund (commonly referred to as an “ETF”). Individual Fund shares may only be purchased and sold on a national securities exchange through a broker-dealer. The price of Fund shares is based on market price, and because ETF shares trade at market prices rather than NAV, shares may trade at a price greater than NAV (a premium) or less than NAV (a discount). The Fund will only issue or redeem shares that have been aggregated into blocks of 50,000 shares or multiples thereof (“Creation Units”) to authorized participants who have entered into agreements with the Fund’s distributor. The Fund generally will issue or redeem Creation Units in return for a designated portfolio of securities (and an amount of cash) that the Fund specifies each day.

Tax Information

The Fund intends to make distributions that may be taxable to you as ordinary income or capital gains, unless you are investing through a tax-deferred arrangement such as a 401(k) plan or an individual retirement account (“IRA”).

Payments to Broker-Dealers and other Financial Intermediaries

If you purchase shares of the Fund through a broker-dealer or other financial intermediary (such as a bank), BFA or other related companies may pay the intermediary for marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems or other services related to the sale or promotion of the Fund. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.

More Information About the Fund

This Prospectus contains important information about investing in the Fund. Please read this Prospectus carefully before you make any investment decisions. Additional information regarding the Fund is available at www.iShares.com.

BFA is the investment adviser to the Fund. Shares of the Fund are listed for trading on The NASDAQ Stock Market (“NASDAQ”). The market price for a share of the Fund may be different from the Fund’s most recent NAV.

ETFs are funds that trade like other publicly-traded securities. The Fund is designed to track an index. Similar to shares of an index mutual fund, each share of the Fund represents a partial ownership in an underlying portfolio of securities intended to track a market index. Unlike shares of a mutual fund, which can be bought and redeemed from the issuing fund by all shareholders at a price based on NAV, shares of the Fund may be purchased or redeemed directly from the Fund at NAV solely by authorized participants. Also unlike shares of a mutual fund, shares of the Fund are listed on a national securities exchange and trade in the secondary market at market prices that change throughout the day.

The Fund invests in a particular segment of the securities markets and seeks to track the performance of a securities index that generally is not representative of the market as a whole. The Fund is designed to be used as part of broader asset allocation strategies. Accordingly, an investment in the Fund should not constitute a complete investment program.

An index is a theoretical financial calculation while the Fund is an actual investment portfolio. The performance of the Fund and the Underlying Index may vary due to transaction costs, non-U.S. currency valuations, asset valuations, corporate actions (such as mergers and spin-offs), timing variances and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions (such as diversification requirements) that apply to the Fund but not to the Underlying Index or to the use of representative sampling. “Tracking error” is the difference between the performance (return) of the Fund’s portfolio and that of the Underlying Index. BFA expects that, over time, the Fund’s tracking error will not exceed 5%. Because the Fund uses a representative sampling indexing strategy, it can be expected to have a larger tracking error than if it used a replication indexing strategy. “Replication” is an indexing strategy in which a fund invests in substantially all of the securities in its underlying index in approximately the same proportions as in the underlying index.

An investment in the Fund is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, BFA or any of its affiliates.

The Fund’s investment objective and the Underlying Index may be changed without shareholder approval.

A Further Discussion of Principal Risks

The Fund is subject to various risks, including the principal risks noted below, any of which may adversely affect the Fund’s NAV, trading price, yield, total return and ability to meet its investment objective. You could lose all or part of your investment in the Fund, and the Fund could underperform other investments.

Asset Class Risk. The securities in the Underlying Index or in the Fund’s portfolio may underperform the returns of other securities or indexes that track other countries, groups of countries, regions, industries, groups of industries, markets, asset classes or sectors. Various types of securities or indexes tend to experience cycles of outperformance and underperformance in comparison to the general securities markets.

Concentration Risk. To the extent that the Fund’s portfolio reflects the Underlying Index’s concentration in the securities of a particular issuer or issuers in a particular country, group of countries, region, market, industry, group of industries, sector or asset class, the Fund may be adversely affected by the performance of those securities, may be subject to increased price volatility and may be more susceptible to adverse economic, market, political or regulatory occurrences affecting that issuer, country, group of countries, region, market, industry, group of industries, sector or asset class.

Currency Risk. Because the Fund’s NAV is determined on the basis of the U.S. dollar, investors may lose money if the currency of a non-U.S. market in which the Fund invests depreciates against the U.S. dollar, even if the local currency value of the Fund’s holdings in that market increases.

Equity Securities Risk. The Fund invests in equity securities, which are subject to changes in value that may be attributable to market perception of a particular issuer or to general stock market fluctuations that affect all issuers. Investments in equity securities may be more volatile than investments in other asset classes.

European Economic Risk. The Economic and Monetary Union of the European Union (the “EU”) requires member countries to comply with restrictions on inflation rates, deficits, interest rates, debt levels and fiscal and monetary controls, each of which may significantly affect every country in Europe. Decreasing imports or exports, changes in governmental or EU regulations on trade, changes in the exchange rate of the euro, the default or threat of default by an EU member country on its sovereign debt, and/or an economic recession in an EU member country may have a significant adverse effect on the economies of EU member countries and their trading partners, including some or all of the financial sectors of the European countries in which the Fund invests. The European financial markets have recently experienced volatility and have been adversely affected by concerns about economic downturns, credit rating downgrades, rising government debt levels and possible default on or restructuring of government debt in several European countries, including Greece, Ireland, Italy, Portugal and Spain. A default or debt restructuring by any European country would adversely impact holders of that country’s debt, and sellers of credit default swaps linked to that country’s creditworthiness, which may be located in countries other than those listed in the previous sentence. These events have adversely affected the value and

exchange rate of the euro and may continue to significantly affect the economies of every country in Europe, including EU member countries that do not use the euro and non-EU member countries.

Financial Sector Risk. Companies in the financial sector of an economy are often subject to governmental regulation and, recently, government intervention and the potential for additional regulation, which may adversely affect the scope of their activities, the prices they can charge and the amount of capital they must maintain. Governmental regulation may change frequently and may have significant adverse consequences for companies in the financial sector, including effects not intended by such regulation. The impact of recent or future regulation in various countries on any individual financial company or on the sector as a whole cannot be predicted. Certain risks may impact the value of investments in the financial sector more severely than investments outside this sector, including the risks associated with companies that operate with substantial financial leverage. Companies in the financial sector may also be adversely affected by increases in interest rates and loan losses, decreases in the availability of money or asset valuations, credit rating downgrades and adverse conditions in other related markets. Over the past few years, the deterioration of the credit markets has impacted a broad range of mortgage, asset-backed, auction rate, sovereign debt and other markets, including U.S. and non-U.S. credit and interbank money markets, thereby affecting a wide range of financial institutions and markets. This situation has created instability in the financial markets and caused certain financial companies to incur large losses. Some financial companies have experienced declines in the valuations of their assets, taken actions to raise capital (such as the issuance of debt or equity securities), or even ceased operations. Some financial companies have borrowed significant amounts of capital from governments and may face future government-imposed restrictions on their businesses or increased government intervention. These actions have caused the securities of many financial companies to decline in value. Insurance companies, in particular, may be subject to severe price competition, which may have an adverse impact on their profitability.

Geographic Risk. Some markets in which the Fund invests are located in parts of the world that have historically been prone to natural disasters, such as earthquakes, volcanoes, droughts, floods, hurricanes and tsunamis, and are economically sensitive to environmental events. Any natural or other disaster could have a significant adverse impact on the economies of these geographic areas, causing an adverse impact on the Fund’s investments in the affected region.

Insurance Industry Risk. The insurance industry is subject to extensive government regulation in some countries and can be significantly affected by changes in interest rates, general economic conditions, price and marketing competition, the imposition of premium rate caps, or other changes in government regulation or tax law. Different segments of the insurance industry can be significantly affected by mortality and morbidity rates, environmental clean-up costs and catastrophic events such as earthquakes, hurricanes and terrorist acts.

Issuer Risk. The performance of the Fund depends on the performance of individual securities to which the Fund has exposure. Any issuer of these securities may perform poorly, causing the value of its securities to decline. Poor performance may be caused

by poor management decisions, competitive pressures, changes in technology, expiration of patent protection, disruptions in supply, labor problems or shortages, corporate restructurings, fraudulent disclosures or other factors. Issuers may, in times of distress or at their own discretion, decide to reduce or eliminate dividends, which may also cause their stock prices to decline.

Management Risk. The Fund may not fully replicate the Underlying Index and may hold securities not included in the Underlying Index. As a result, the Fund is subject to the risk that BFA’s investment management strategy, the implementation of which is subject to a number of constraints, may not produce the intended results.

Market Risk. The Fund could lose money due to short-term market movements and over longer periods during market downturns. Securities may decline in value due to factors affecting securities markets generally or particular industries represented in the markets. The value of a security may decline due to general market conditions, economic trends or events that are not specifically related to the issuer of the security or to factors that affect a particular industry or industries. During a general downturn in the securities markets, multiple asset classes may be negatively affected.

Market Trading Risk

Absence of Active Market. Although shares of the Fund are listed for trading on one or more stock exchanges, there can be no assurance that an active trading market for such shares will develop or be maintained.

Risk of Secondary Listings. The Fund’s shares may be listed or traded on U.S. and non-U.S. stock exchanges other than the U.S. stock exchange where the Fund’s primary listing is maintained. There can be no assurance that the Fund’s shares will continue to trade on any such stock exchange or in any market or that the Fund’s shares will continue to meet the requirements for listing or trading on any exchange or in any market. The Fund’s shares may be less actively traded in certain markets than others, and investors are subject to the execution and settlement risks and market standards of the market where they or their broker direct their trades for execution. Certain information available to investors who trade Fund shares on a U.S. stock exchange during regular U.S. market hours may not be available to investors who trade in other markets, which may result in secondary market prices in such markets being less efficient.

Secondary Market Trading Risk. Shares of the Fund may trade in the secondary market at times when the Fund does not accept orders to purchase or redeem shares. At such times, shares may trade in the secondary market with more significant premiums or discounts than might be experienced at times when the Fund accepts purchase and redemption orders.

Secondary market trading in Fund shares may be halted by a stock exchange because of market conditions or other reasons. In addition, trading in Fund shares on a stock exchange or in any market may be subject to trading halts caused by extraordinary market volatility pursuant to “circuit breaker” rules on the stock exchange or market. There can be no assurance that the requirements necessary to maintain the listing or trading of Fund shares will continue to be met or will remain unchanged.

Shares of the Fund May Trade at Prices Other Than NAV. Shares of the Fund trade on stock exchanges at prices at, above or below their most recent NAV. The NAV of the Fund is calculated at the end of each business day and fluctuates with changes in the market value of the Fund’s holdings since the most recent calculation. The trading prices of the Fund’s shares fluctuate continuously throughout trading hours based on market supply and demand rather than NAV. The trading prices of the Fund’s shares may deviate significantly from NAV during periods of market volatility. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV. However, because shares can be created and redeemed in Creation Units at NAV (unlike shares of many closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their NAVs), BFA believes that large discounts or premiums to the NAV of the Fund are not likely to be sustained over the long-term. While the creation/redemption feature is designed to make it likely that the Fund’s shares normally will trade on stock exchanges at prices close to the Fund’s next calculated NAV, exchange prices are not expected to correlate exactly with the Fund’s NAV due to timing reasons as well as market supply and demand factors. In addition, disruptions to creations and redemptions or extreme market volatility may result in trading prices for shares of the Fund that differ significantly from its NAV.

Costs of Buying or Selling Fund Shares. Buying or selling Fund shares on an exchange involves two types of costs that apply to all securities transactions. When buying or selling shares of the Fund through a broker, you will likely incur a brokerage commission or other charges imposed by brokers as determined by that broker. In addition, you may incur the cost of the “spread” – that is, the difference between what investors are willing to pay for Fund shares (the “bid” price) and the price at which they are willing to sell Fund shares (the “ask” price). Because of the costs inherent in buying or selling Fund shares, frequent trading may detract significantly from investment results and an investment in Fund shares may not be advisable for investors who anticipate regularly making small investments.

Mid-Capitalization Companies Risk. Many of the companies in which the Fund invests are considered mid-capitalization companies. Stock prices of mid-capitalization companies may be more volatile than those of large-capitalization companies and, therefore, the Fund’s share price may be more volatile than those of funds that invest a larger percentage of their assets in stocks issued by large-capitalization companies. Stock prices of mid-capitalization companies are also more vulnerable than those of large-capitalization companies to adverse business or economic developments, and the stocks of mid-capitalization companies may be less liquid, making it difficult for the Fund to buy and sell them. In addition, mid-capitalization companies generally have less diverse product lines than large-capitalization companies and are more susceptible to adverse developments related to their products.

Non-Diversification Risk. The Fund is classified as “non-diversified.” This means that the Fund may invest a large percentage of its assets in securities issued by or representing a small number of issuers. As a result, the Fund may be more susceptible to the risks associated with these particular issuers, or to a single economic, political or regulatory occurrence affecting these issuers.

Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers are subject to all of the risks of investing in the markets where such issuers are located, including heightened risks of inflation or nationalization and market fluctuations caused by economic and political developments. As a result of investing in non-U.S. securities, the Fund may be subject to increased risk of loss caused by any of the factors listed below:

  • Lower levels of liquidity and market efficiency;
  • Greater securities price volatility;
  • Exchange rate fluctuations and exchange controls;
  • Less availability of public information about issuers;
  • Limitations on foreign ownership of securities;
  • Imposition of withholding or other taxes;
  • Imposition of restrictions on the expatriation of the funds or other assets of the Fund;
  • Higher transaction and custody costs and delays in settlement procedures;
  • Difficulties in enforcing contractual obligations;
  • Lower levels of regulation of the securities market;
  • Weaker accounting, disclosure and reporting requirements; and
  • Legal principles related to corporate governance, directors’ fiduciary duties and liabilities and stockholders’ rights in markets in which the Fund invests may differ and/or may not be as extensive or protective as those that apply in the United States.

Passive Investment Risk. The Fund is not actively managed and may be affected by a general decline in market segments related to the Underlying Index. The Fund invests in securities included in, or representative of, the Underlying Index regardless of their investment merits. BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

Privatization Risk. Some countries in which the Fund invests have begun a process of privatizing certain entities and industries. In some instances, investors in newly privatized entities have suffered losses due to the inability of the newly privatized entities to adjust quickly to a competitive environment or changing regulatory and legal standards or, in some cases, due to re-nationalization of such privatized entities. There is no assurance that such losses will not recur.

Reliance on Trading Partners Risk. The economies of the Europe financial sector countries are dependent on each other and on the United States as key trading partners. Reduction in spending on the products and services of the Europe financial sector countries by any of their key trading partners, institution of tariffs or other trade barriers or a slowdown in the economies of any of their key trading partners may cause an adverse impact on the economies of the Europe financial sector countries.


U.S. Trading Partners Risk. The United States is a significant, and in some cases the most significant, trading partner of or foreign investor in certain Europe financial sector countries and the economies of these countries may be particularly affected by

changes in the U.S. economy. Decreasing U.S. imports, new trade regulations, changes in the U.S. dollar exchange rate or a recession in the United States may have a material adverse effect on the economies of Europe financial sector countries.

Risk of Investing in the United Kingdom. Investment in British issuers may subject the Fund to regulatory, political, currency, security, and economic risk specific to the United Kingdom. The British economy relies heavily on export of financial services to the United States and other European countries. A prolonged slowdown in the financial services sector will have a negative impact on the British economy. In the past, the United Kingdom has been a target of terrorism. Acts of terrorism in the United Kingdom or against British interests abroad may cause uncertainty in the British financial markets and adversely affect the performance of the issuers to which the Fund has exposure. The British economy, along with the United States and certain other European economies, experienced a significant economic slowdown during the recent financial crisis.

Securities Lending Risk. The Fund may engage in securities lending. Securities lending involves the risk that the Fund may lose money because the borrower of the Fund’s loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for the loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Small-Capitalization Companies Risk. Many of the companies in which the Fund invests are considered small-capitalization companies. Stock prices of small-capitalization companies may be more volatile than those of larger companies and, therefore, the Fund’s share price may be more volatile than those of funds that invest a larger percentage of their assets in stocks issued by mid- or large-capitalization companies. Stock prices of small-capitalization companies are generally more vulnerable than those of mid- or large-capitalization companies to adverse business and economic developments. Securities of small-capitalization companies may be thinly traded, making it difficult for the Fund to buy and sell them. In addition, small-capitalization companies are typically less financially stable than larger, more established companies and may depend on a small number of essential personnel, making them more vulnerable to loss of personnel. Small-capitalization companies also normally have less diverse product lines than mid- or large-capitalization companies and are more susceptible to adverse developments concerning their products.

Structural Risk. Certain political, economic, legal and currency risks have contributed to a high degree of price volatility in the equity markets of the countries in which the Fund invests and could adversely affect investments in the Fund:

Political and Social Risk. Disparities of wealth, the pace and success of democratization and ethnic, religious and racial disaffection, among other factors, have led to social unrest, violence and labor unrest in some countries in which the Fund invests. Unanticipated or sudden political or social developments may result in sudden and significant investment losses.

Economic Risk. Some countries in which the Fund invests may experience economic instability, including instability resulting from substantial rates of inflation or significant devaluations of their currency, or economic recessions causing a negative effect on the economies and securities markets of their economies. Some of these countries may also impose restrictions on the exchange or export of currency or adverse currency exchange rates and may be characterized by a lack of available currency hedging instruments.

Expropriation and/or Nationalization Risk. Investments in certain countries in which the Fund invests may be subject to loss due to expropriation or nationalization of assets and property or the imposition of restrictions on foreign investments and repatriation of capital.

Large Government Debt Risk. Chronic structural public sector deficits in some countries in which the Fund invests may adversely impact investments in the Fund.

Tracking Error Risk. Imperfect correlation between the Fund’s portfolio securities and those in the Underlying Index, rounding of prices, changes to the Underlying Index and regulatory requirements may cause tracking error, which is the divergence of the Fund’s performance from that of the Underlying Index. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Underlying Index does not. Because the Fund employs a representative sampling strategy, the Fund may experience tracking error to a greater extent than a fund that seeks to replicate an index.

Valuation Risk. Because non-U.S. exchanges may be open on days when the Fund does not price its shares, the value of the securities in the Fund’s portfolio may change on days when shareholders will not be able to purchase or sell the Fund’s shares. In addition, for purposes of calculating the Fund’s NAV, the value of assets denominated in non-U.S. currencies is converted into U.S. dollars using exchange rates deemed appropriate by BFA. This conversion may result in a difference between the prices used to calculate the Fund’s NAV and the prices used by the Underlying Index, which, in turn, could result in a difference between the Fund’s performance and the performance of the Underlying Index.

Portfolio Holdings Information

A description of the Trust’s policies and procedures with respect to the disclosure of the Fund’s portfolio securities is available in the Fund’s Statement of Additional Information (“SAI”). The top holdings of the Fund can be found at www.iShares.com. Fund fact sheets provide information regarding the Fund’s top holdings and may be requested by calling 1-800-iShares (1-800-474-2737).

Management

Investment Adviser. As investment adviser, BFA has overall responsibility for the general management and administration of the Trust. BFA provides an investment program for the Fund and manages the investment of the Fund’s assets. In managing the Fund, BFA may draw upon the research and expertise of its asset management

affiliates with respect to certain portfolio securities. In seeking to achieve the Fund’s investment objective, BFA uses teams of portfolio managers, investment strategists and other investment specialists. This team approach brings together many disciplines and leverages BFA’s extensive resources.

Pursuant to the Investment Advisory Agreement between BFA and the Trust (entered into on behalf of the Fund), BFA is responsible for substantially all expenses of the Fund, except interest expenses, taxes, brokerage expenses, future distribution fees or expenses and extraordinary expenses.

For its investment advisory services to the Fund, BFA is entitled to receive a management fee from the Fund based on a percentage of the Fund’s average daily net assets, at the annual rate of 0.48%.

BFA is located at 400 Howard Street, San Francisco, CA 94105. It is a wholly owned subsidiary of BTC, which in turn is indirectly wholly-owned by BlackRock, Inc. (“BlackRock”). As of September 30, 2011, BTC and its affiliates, including BFA and BlackRock, provided investment advisory services for assets in excess of $3.35 trillion. BFA, BTC, BlackRock Execution Services, BlackRock and their affiliates deal, trade and invest for their own accounts in the types of securities in which the Fund may also invest.

A discussion regarding the basis for the Trust’s Board of Trustees’ (the “Board”) approval of the Investment Advisory Agreement with BFA is available in the Fund’s annual report for the period ended July 31.

Portfolio Managers. Rene Casis, Diane Hsiung and Greg Savage are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager is responsible for various functions related to portfolio management, including, but not limited to, investing cash inflows, coordinating with members of his or her portfolio management team to focus on certain asset classes, implementing investment strategy, researching and reviewing investment strategy and overseeing members of his or her portfolio management team that have more limited responsibilities.

Rene Casis has been employed by BFA (formerly, Barclays Global Fund Advisors (“BGFA”)) and BTC (formerly, Barclays Global Investors, N.A. (“BGI”)) as a senior portfolio manager since 2009. From 2005 to 2009, Mr. Casis was a trader at Barclays Capital. Prior to that, Mr. Casis was a portfolio manager from 2000 to 2005 for BGFA and BGI. Mr. Casis has been a Portfolio Manager of the Fund since 2010.

Diane Hsiung has been employed by BFA and BTC as a senior portfolio manager since 2007. Prior to that, Ms. Hsiung was a portfolio manager from 2002 to 2006 for BGFA and BGI. Ms. Hsiung has been a Portfolio Manager of the Fund since inception.

Greg Savage has been employed by BFA and BTC as a senior portfolio manager since 2006. Prior to that, Mr. Savage was a portfolio manager from 2001 to 2006 for BGFA and BGI. Mr. Savage has been a Portfolio Manager of the Fund since inception.

The Fund’s SAI provides additional information about the Portfolio Managers’ compensation, other accounts managed by the Portfolio Managers and the Portfolio Managers’ ownership (if any) of shares in the Fund.

Administrator, Custodian and Transfer Agent. State Street Bank and Trust Company (“State Street”) is the administrator, custodian and transfer agent for the Fund.

Conflicts of Interest. BFA wants you to know that there are certain entities with which BFA has relationships that may give rise to conflicts of interest, or the appearance of conflicts of interest. These entities include the following: BFA’s affiliates (including BlackRock and The PNC Financial Services Group, Inc., and each of their affiliates, directors, partners, trustees, managing members, officers and employees (collectively, the “Affiliates”)) and BlackRock’s significant shareholder, Barclays Bank PLC and its affiliates, including Barclays PLC (each, an “Entity” and together, the “Entities”).

The activities of BFA, the Affiliates and the Entities in the management of, or their interest in, their own accounts and other accounts they manage, may present conflicts of interest that could disadvantage the Fund and its shareholders. BFA and its Affiliates or the Entities provide investment management services to other funds and discretionary managed accounts that may follow an investment program similar to that of the Fund. BFA, its Affiliates and the Entities are involved worldwide with a broad spectrum of financial services and asset management activities and may engage in the ordinary course of business in activities in which their interests or the interests of their clients may conflict with those of the Fund. BFA, one or more of the Affiliates or the Entities acts, or may act, as an investor, investment banker, research provider, investment manager, financier, underwriter, advisor, market maker, trader, prime broker, lender, agent or principal, and have other direct and indirect interests, in securities, currencies and other instruments in which the Fund may directly or indirectly invest. Thus, it is likely that the Fund will have multiple business relationships with and will invest in, engage in transactions with, make voting decisions with respect to, or obtain services from, entities for which BFA, an Affiliate or an Entity performs or seeks to perform investment banking or other services.

BFA or one or more Affiliates or Entities may engage in proprietary trading and advise accounts and funds that have investment objectives similar to those of the Fund and/or that engage in and compete for transactions in the same types of securities, currencies and other instruments as the Fund, including in securities issued by other open-end and closed-end investment management companies, including investment companies that are affiliated with the Fund and BFA, to the extent permitted under the Investment Company Act of 1940, as amended (the “1940 Act”). The trading activities of BFA, these Affiliates and Entities are carried out without reference to positions held directly or indirectly by the Fund and may result in BFA, an Affiliate or an Entity having positions that are adverse to those of the Fund.

No Affiliate or Entity is under any obligation to share any investment opportunity, idea or strategy with the Fund. As a result, an Affiliate or an Entity may compete with the Fund for appropriate investment opportunities. As a result of this and several other factors, the results of the Fund’s investment activities may differ from those of an Affiliate or an Entity and of other accounts managed by an Affiliate or an Entity, and it is possible that the Fund could sustain losses during periods in which one or more

Affiliates or Entities and other accounts achieve profits on their trading for proprietary or other accounts. The opposite result is also possible.

The Fund may, from time to time, enter into transactions in which BFA or an Affiliate’s or an Entity’s clients have an interest adverse to the Fund. Furthermore, transactions undertaken by Affiliate-advised clients may adversely impact the Fund. Transactions by one or more Affiliate- or Entity-advised clients or BFA may have the effect of diluting or otherwise disadvantaging the values, prices or investment strategies of the Fund.

An Entity may maintain securities indices as part of its product offerings. Index-based funds seek to track the performance of securities indices and may use the name of the index in the fund name. Index providers, including the Entities, may be paid licensing fees for use of their indices or index names. Entities will not be obligated to license their indices to BFA and its Affiliates, and BFA and its Affiliates will not be assured that the terms of any index licensing agreement with the Entities will be as favorable as those terms offered to other index licensees.

The Fund’s activities may be limited because of regulatory restrictions applicable to one or more Affiliates or Entities, and/or their internal policies designed to comply with such restrictions. In addition, the Fund may invest in securities of companies with which an Affiliate or an Entity has or is trying to develop investment banking relationships or in which an Affiliate or an Entity has significant debt or equity investments. The Fund also may invest in securities of companies for which an Affiliate or an Entity provides or may some day provide research coverage. An Affiliate or an Entity may have business relationships with and purchase or distribute or sell services or products from or to distributors, consultants or others who recommend the Fund or who engage in transactions with or for the Fund, and may receive compensation for such services. The Fund may also make brokerage and other payments to Affiliates or Entities in connection with the Fund’s portfolio investment transactions.

Pursuant to a securities lending program approved by the Board, the Fund has retained an Affiliate of BFA to serve as the securities lending agent for the Fund to the extent that the Fund participates in the securities lending program. For these services, the lending agent may receive a fee from the Fund, including a fee based on the returns earned on the Fund’s investment of the cash received as collateral for any loaned securities. In addition, one or more Affiliates may be among the entities to which the Fund may lend its portfolio securities under the securities lending program.

The activities of BFA, the Affiliates or Entities may give rise to other conflicts of interest that could disadvantage the Fund and its shareholders. BFA has adopted policies and procedures designed to address these potential conflicts of interest. See the Fund’s SAI for further information.

Shareholder Information

Additional shareholder information, including how to buy and sell shares of the Fund, is available free of charge by calling toll-free: 1-800-iShares (1-800-474-2737) or visiting our website at www.iShares.com.

Buying and Selling Shares. Shares of the Fund may be acquired or redeemed directly from the Fund only in Creation Units or multiples thereof, as discussed in the Creations

and Redemptions section of this Prospectus. Only an Authorized Participant (as defined in the Creations and Redemptions section) may engage in creation or redemption transactions directly with the Fund. Once created, shares of the Fund generally trade in the secondary market in amounts less than a Creation Unit.

Shares of the Fund are listed on a national securities exchange for trading during the trading day. Shares can be bought and sold throughout the trading day like shares of other publicly-traded companies. The Trust does not impose any minimum investment for shares of the Fund purchased on an exchange. The Fund’s shares trade under the trading symbol “EUFN.”

Buying or selling Fund shares on an exchange involves two types of costs that may apply to all securities transactions. When buying or selling shares of the Fund through a broker, you will likely incur a brokerage commission or other charges determined by your broker. The commission is frequently a fixed amount and may be a significant proportional cost for investors seeking to buy or sell small amounts of shares. In addition, you may incur the cost of the “spread” – that is, any difference between the bid price and the ask price. The spread varies over time for shares of the Fund based on its trading volume and market liquidity, and is generally lower if the Fund has a lot of trading volume and market liquidity, and higher if the Fund has little trading volume and market liquidity.

The Board has adopted a policy of not monitoring for frequent purchases and redemptions of Fund shares (“frequent trading”) that appear to attempt to take advantage of a potential arbitrage opportunity presented by a lag between a change in the value of the Fund’s portfolio securities after the close of the primary markets for the Fund’s portfolio securities and the reflection of that change in the Fund’s NAV (“market timing”), because the Fund generally sells and redeems its shares directly through transactions that are in-kind and/or for cash, subject to the conditions described below under Creations and Redemptions. The Board has not adopted a policy of monitoring for other frequent trading activity because shares of the Fund are listed for trading on a national securities exchange.

The national securities exchange on which the Fund’s shares are listed is open for trading Monday through Friday and is closed on weekends and the following holidays: New Year’s Day, Martin Luther King, Jr. Day, Presidents’ Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day. The Fund’s primary listing exchange is NASDAQ.

Section 12(d)(1) of the 1940 Act restricts investments by investment companies in the securities of other investment companies. Registered investment companies are permitted to invest in the Fund beyond the limits set forth in Section 12(d)(1), subject to certain terms and conditions set forth in SEC rules or in an SEC exemptive order issued to the Trust. In order for a registered investment company to invest in shares of the Fund beyond the limitations of Section 12(d)(1) pursuant to the exemptive relief obtained by the Trust, the registered investment company must enter into an agreement with the Trust.

Book Entry. Shares of the Fund are held in book-entry form, which means that no stock certificates are issued. The Depository Trust Company (“DTC”) or its nominee is

the record owner of all outstanding shares of the Fund and is recognized as the owner of all shares for all purposes.

Investors owning shares of the Fund are beneficial owners as shown on the records of DTC or its participants. DTC serves as the securities depository for shares of the Fund. DTC participants include securities brokers and dealers, banks, trust companies, clearing corporations and other institutions that directly or indirectly maintain a custodial relationship with DTC. As a beneficial owner of shares, you are not entitled to receive physical delivery of stock certificates or to have shares registered in your name, and you are not considered a registered owner of shares. Therefore, to exercise any right as an owner of shares, you must rely upon the procedures of DTC and its participants. These procedures are the same as those that apply to any other securities that you hold in book-entry or “street name” form.

Share Prices. The trading prices of the Fund’s shares in the secondary market generally differ from the Fund’s daily NAV and are affected by market forces such as supply and demand, economic conditions and other factors. Information regarding the intraday value of shares of the Fund, also known as the “indicative optimized portfolio value” (“IOPV”), is disseminated every 15 seconds throughout the trading day by the national securities exchange on which the Fund’s shares are listed or by market data vendors or other information providers. The IOPV is based on the current market value of the securities and/or cash required to be deposited in exchange for a Creation Unit. The IOPV does not necessarily reflect the precise composition of the current portfolio of securities held by the Fund at a particular point in time or the best possible valuation of the current portfolio. Therefore, the IOPV should not be viewed as a “real-time” update of the Fund’s NAV, which is computed only once a day. The IOPV is generally determined by using both current market quotations and/or price quotations obtained from broker-dealers that may trade in the portfolio securities held by the Fund. The quotations of certain Fund holdings may not be updated during U.S. trading hours if such holdings do not trade in the United States. The Fund is not involved in, or responsible for, the calculation or dissemination of the IOPV and makes no representation or warranty as to its accuracy.

Determination of Net Asset Value. The NAV of the Fund normally is determined once daily Monday through Friday, generally as of the regularly scheduled close of business of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m., Eastern time) on each day that the NYSE is open for trading, based on prices at the time of closing provided that (a) any Fund assets or liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers (as detailed below) and (b) U.S. fixed income assets may be valued as of the announced closing time for trading in fixed income instruments in a particular market or exchange. The NAV of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets held by the Fund, and its liabilities, are determined pursuant to valuation policies and procedures approved by the Board. The Fund’s assets and liabilities are valued primarily on the basis of market quotations.

Equity investments are valued at market value, which is generally determined using the last reported official closing price or last trading price on the exchange or market on which the security is primarily traded at the time of valuation.

The Fund invests in foreign securities. Foreign currency exchange rates are generally determined as of 4:00 p.m., London time. Foreign securities owned by the Fund may trade on weekends or other days when the Fund does not price its shares. As a result, the Fund’s NAV may change on days when Authorized Participants will not be able to purchase or redeem Fund shares.

Generally, trading in foreign securities, U.S. government securities, money market instruments and certain fixed-income securities is substantially completed each day at various times prior to the close of business on the NYSE. The values of such securities used in computing the NAV of the Fund are determined as of such times.

When market quotations are not readily available or are believed by BFA to be unreliable, the Fund’s investments are valued at fair value. Fair value determinations are made by BFA in accordance with policies and procedures approved by the Fund’s Board. BFA may conclude that a market quotation is not readily available or is unreliable if a security or other asset or liability does not have a price source due to its lack of liquidity, if a market quotation differs significantly from recent price quotations or otherwise no longer appears to reflect fair value, where the security or other asset or liability is thinly traded, or where there is a significant event subsequent to the most recent market quotation. A “significant event” is an event that, in the judgment of BFA, is likely to cause a material change to the closing market price of the asset or liability held by the Fund. Foreign securities whose values are affected by volatility that occurs in U.S. markets on a trading day after the close of foreign securities markets may be fair valued.

Fair value represents a good faith approximation of the value of an asset or liability. The fair value of an asset or liability held by the Fund is the amount the Fund might reasonably expect to receive from the current sale of that asset or the cost to extinguish that liability in an arm’s-length transaction. Valuing the Fund’s investments using fair value pricing will result in prices that may differ from current market valuations and that may not be the price at which those investments could have been sold during the period in which the particular fair values were used. Use of fair value prices and certain current market valuations could result in a difference between the prices used to calculate the Fund’s NAV and the prices used by the Underlying Index, which, in turn, could result in a difference between the Fund’s performance and the performance of the Underlying Index.

The value of assets or liabilities denominated in non-U.S. currencies will be converted into U.S. dollars using exchange rates deemed appropriate by BFA as investment adviser. Use of a rate different from the rate used by the Index Provider may adversely affect the Fund’s ability to track the Underlying Index.

Dividends and Distributions

General Policies. Dividends from net investment income, if any, generally are declared and paid semi-annually by the Fund. Distributions of net realized securities gains, if any, generally are declared and paid once a year, but the Trust may make distributions on a more frequent basis for the Fund. The Trust reserves the right to declare special distributions if, in its reasonable discretion, such action is necessary or advisable to preserve its status as a regulated investment company (“RIC”) or to avoid imposition of income or excise taxes on undistributed income or realized gains.

Dividends and other distributions on shares of the Fund are distributed on a pro rata basis to beneficial owners of such shares. Dividend payments are made through DTC participants and indirect participants to beneficial owners then of record with proceeds received from the Fund.

Dividend Reinvestment Service. No dividend reinvestment service is provided by the Trust. Broker-dealers may make available the DTC book-entry Dividend Reinvestment Service for use by beneficial owners of the Fund for reinvestment of their dividend distributions. Beneficial owners should contact their broker to determine the availability and costs of the service and the details of participation therein. Brokers may require beneficial owners to adhere to specific procedures and timetables. If this service is available and used, dividend distributions of both income and realized gains will be automatically reinvested in additional whole shares of the Fund purchased in the secondary market.

Taxes. As with any investment, you should consider how your investment in shares of the Fund will be taxed. The tax information in this Prospectus is provided as general information, based on current law. You should consult your own tax professional about the tax consequences of an investment in shares of the Fund.

Unless your investment in Fund shares is made through a tax-exempt entity or tax-deferred retirement account, such as an IRA, you need to be aware of the possible tax consequences when the Fund makes distributions or you sell Fund shares.

Taxes on Distributions. Distributions from the Fund’s net investment income (other than qualified dividend income), including distributions of income from securities lending and distributions out of the Fund’s net short-term capital gains, if any, are taxable to you as ordinary income. Distributions by the Fund of net long-term capital gains in excess of net short-term capital losses (capital gain dividends) are taxable to you as long-term capital gains, generally at a 15% tax rate (0% at certain income levels), regardless of how long you have held the Fund’s shares. Distributions by the Fund that qualify as qualified dividend income are taxable to you at long-term capital gain rates for taxable years beginning on or before December 31, 2012. The 15% and 0% tax rates expire for taxable years beginning after December 31, 2012. Maximum long-term capital gain income tax rates are scheduled to rise to 20% in 2013. Beginning in 2013, a 3.8% U.S. federal Medicare contribution tax will be imposed on “net investment income,” including interest, dividends, and capital gains, of U.S. individuals with income exceeding $200,000 (or $250,000 if married and filing jointly), and of estates and trusts.

Dividends will be qualified dividend income to you if they are attributable to qualified dividend income received by the Fund. Generally, qualified dividend income includes dividend income from taxable U.S. corporations and qualified non-U.S. corporations, provided that the Fund satisfies certain holding period requirements in respect of the stock of such corporations and has not hedged its position in the stock in certain ways. Substitute dividends received by the Fund with respect to dividends paid on securities lent out will not be qualified dividend income. For this purpose, a qualified non-U.S. corporation means any non-U.S. corporation that is eligible for benefits under a comprehensive income tax treaty with the United States, which includes an exchange of information program or if the stock with respect to which the dividend was paid is readily tradable on an established United States securities market. The term excludes a corporation that is a passive foreign investment company.

Dividends received by the Fund from a REIT or another RIC generally are qualified dividend income only to the extent the dividend distributions are made out of qualified dividend income received by such REIT or RIC. It is expected that dividends received by the Fund from a REIT and distributed to a shareholder generally will be taxable to the shareholder as ordinary income.

For a dividend to be treated as qualified dividend income, the dividend must be received with respect to a share of stock held without being hedged by the Fund, and with respect to a share of the Fund held without being hedged by you, for 61 days during the 121-day period beginning at the date which is 60 days before the date on which such share becomes ex-dividend with respect to such dividend or, in the case of certain preferred stock, 91 days during the 181-day period beginning 90 days before such date.

If your Fund shares are loaned out pursuant to a securities lending arrangement, you may lose the ability to use foreign tax credits passed through by the Fund or to treat Fund dividends paid while the shares are held by the borrower as qualified dividend income.

In general, your distributions are subject to U.S. federal income tax for the year when they are paid. Certain distributions paid in January, however, may be treated as paid on December 31 of the prior year.

If the Fund’s distributions exceed current and accumulated earnings and profits, all or a portion of the distributions made in the taxable year may be recharacterized as a return of capital to shareholders. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and result in a higher capital gain or lower capital loss when those shares on which the distribution was received are sold. Once a shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain, if the shareholder holds shares of the Fund as capital assets.

If you are neither a resident nor a citizen of the United States or if you are a non-U.S. entity, the Fund’s ordinary income dividends (which include distributions of net short-term capital gains) will generally be subject to a 30% U.S. withholding tax, unless a lower treaty rate applies, provided that withholding tax will generally not apply to any gain or income realized by a non-U.S. shareholder in respect of any distributions of long-term capital gains or upon the sale or other disposition of shares of the Fund.

A 30% withholding tax will be imposed on dividends paid after December 31, 2013, and redemption proceeds paid after December 31, 2014, to (i) foreign financial institutions including non-U.S. investment funds unless they agree to collect and disclose to the Internal Revenue Service (“IRS”) information regarding their direct and indirect U.S. account holders and (ii) certain other foreign entities, unless they certify certain information regarding their direct and indirect U.S. owners. To avoid withholding, foreign financial institutions will need to enter into agreements with the IRS that state that they will provide the IRS information, including the name, address and taxpayer identification number of direct and indirect U.S. account holders, comply with due diligence procedures with respect to the identification of U.S. accounts, report to the IRS certain information with respect to U.S. accounts maintained, agree to withhold tax on certain payments made to non-compliant foreign financial institutions or to account holders who fail to provide the required information, and determine certain other information as to their account holders. Other foreign entities will need to provide the name, address, and taxpayer identification number of each substantial U.S. owner or certifications of no substantial U.S. ownership unless certain exceptions apply.

Dividends, interest and capital gains earned by the Fund with respect to non-U.S. securities may give rise to withholding and other taxes imposed by non-U.S. countries. Tax conventions between certain countries and the United States may reduce or eliminate such taxes. If more than 50% of the total assets of the Fund at the close of a year consists of non-U.S. stocks or securities, the Fund may “pass through” to you certain non-U.S. income taxes (including withholding taxes) paid by the Fund. This means that you would be considered to have received as an additional dividend your share of such non-U.S. taxes, but you may be entitled to either a corresponding tax deduction in calculating your taxable income, or, subject to certain limitations, a credit in calculating your U.S. federal income tax.

For purposes of foreign tax credits for U.S. shareholders of the Fund, foreign capital gains taxes may not produce associated foreign source income, thereby limiting a U.S. person’s ability to use such credits.

If you are a resident or a citizen of the United States, by law, back-up withholding will apply to your distributions and proceeds if you have not provided a taxpayer identification number or social security number and made other required certifications.

Taxes When Shares are Sold. Currently, any capital gain or loss realized upon a sale of Fund shares is generally treated as a long-term gain or loss if the shares have been held for more than one year. Any capital gain or loss realized upon a sale of Fund shares held for one year or less is generally treated as short-term gain or loss, except that any capital loss on the sale of shares held for six months or less is treated as long-term capital loss to the extent that capital gain dividends were paid with respect to such shares. Beginning in 2013, any such capital gains, including from sales of Fund shares or from capital gain dividends, will be included in “net investment income” for purposes of the 3.8% U.S. federal Medicare contribution tax mentioned above.

The foregoing discussion summarizes some of the consequences under current U.S. federal tax law of an investment in the Fund. It is not a substitute for personal tax advice. You may also be subject to state and local taxation on Fund distributions and sales of

shares. Consult your personal tax adviser about the potential tax consequences of an investment in shares of the Fund under all applicable tax laws.

Creations and Redemptions. Prior to trading in the secondary market, shares of the Fund are “created” at NAV by market makers, large investors and institutions only in block-size Creation Units of 50,000 shares or multiples thereof. Each “creator” or “Authorized Participant” enters into an authorized participant agreement with the Fund’s distributor, SEI Investments Distribution Co. (the “Distributor”). Only an Authorized Participant may create or redeem Creation Units directly with the Fund. A creation transaction, which is subject to acceptance by the transfer agent, generally takes place when an Authorized Participant deposits into the Fund a designated portfolio of securities and a specified amount of cash approximating the holdings of the Fund in exchange for a specified number of Creation Units. To the extent practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund.

Similarly, shares can be redeemed only in Creation Units, generally for a designated portfolio of securities and a specified amount of cash held by the Fund (“Fund Securities”). Except when aggregated in Creation Units, shares are not redeemable by the Fund. The prices at which creations and redemptions occur are based on the next calculation of NAV after an order is received in a form described in the authorized participant agreement.

The Fund intends to comply with the U.S. federal securities laws in accepting securities for deposit and satisfying redemptions with redemption securities by, among other means, assuring that any securities accepted for deposit and any securities used to satisfy redemption requests will be sold in transactions that would be exempt from registration under the Securities Act of 1933, as amended (the “1933 Act”). Further, an Authorized Participant that is not a “qualified institutional buyer,” as such term is defined under Rule 144A of the 1933 Act, will not be able to receive Fund Securities that are restricted securities eligible for resale under Rule 144A.

Creations and redemptions must be made through a firm that is either a member of the Continuous Net Settlement System of the National Securities Clearing Corporation or a DTC participant and has executed an agreement with the Distributor with respect to creations and redemptions of Creation Unit aggregations. Information about the procedures regarding creation and redemption of Creation Units (including the cut-off times for receipt of creation and redemption orders) is included in the Fund’s SAI.

Because new shares may be created and issued on an ongoing basis, at any point during the life of the Fund a “distribution,” as such term is used in the 1933 Act, may be occurring. Broker-dealers and other persons are cautioned that some activities on their part may, depending on the circumstances, result in their being deemed participants in a distribution in a manner that could render them statutory underwriters and subject to the prospectus delivery and liability provisions of the 1933 Act. Any determination of whether one is an underwriter must take into account all the relevant facts and circumstances of each particular case.

Broker-dealers should also note that dealers who are not “underwriters” but are participating in a distribution (as contrasted to ordinary secondary transactions), and

thus dealing with shares that are part of an “unsold allotment” within the meaning of Section 4(3)(C) of the 1933 Act, would be unable to take advantage of the prospectus delivery exemption provided by Section 4(3) of the 1933 Act. For delivery of prospectuses to exchange members, the prospectus delivery mechanism of Rule 153 under the 1933 Act is available only with respect to transactions on a national securities exchange.

Costs Associated with Creations and Redemptions. Authorized Participants are charged standard creation and redemption transaction fees to offset transfer and other transaction costs associated with the issuance and redemption of Creation Units. The standard creation and redemption transaction fees are set forth in the table below. The standard creation transaction fee is charged to the Authorized Participant on the day such Authorized Participant creates a Creation Unit, and is the same regardless of the number of Creation Units purchased by the Authorized Participant on the applicable business day. Similarly, the standard redemption transaction fee is charged to the Authorized Participant on the day such Authorized Participant redeems a Creation Unit, and is the same regardless of the number of Creation Units redeemed by the Authorized Participant on the applicable business day. Creations and redemptions for cash (when cash creations and redemptions (in whole or in part) are available or specified) are also subject to an additional charge (up to the maximum amounts shown in the table below). This charge is intended to compensate for brokerage, tax, foreign exchange, execution, market impact and other costs and expenses related to cash transactions. Investors who use the services of a broker or other financial intermediary may pay fees for such services.

The following table shows, as of September 30, 2011, the approximate value of one Creation Unit, standard fees and maximum additional charges for creations and redemptions (as described above):

Householding. Householding is an option available to certain Fund investors. Householding is a method of delivery, based on the preference of the individual investor, in which a single copy of certain shareholder documents can be delivered to investors who share the same address, even if their accounts are registered under different names. Please contact your broker-dealer if you are interested in enrolling in householding and receiving a single copy of prospectuses and other shareholder documents, or if you are currently enrolled in householding and wish to change your householding status.

Distribution

The Distributor distributes Creation Units for the Fund on an agency basis. The Distributor does not maintain a secondary market in shares of the Fund. The Distributor has no role in determining the policies of the Fund or the securities that are purchased or sold by the Fund. The Distributor’s principal address is One Freedom Valley Drive, Oaks, PA 19456.

In addition, BFA or its Affiliates make payments to broker-dealers, banks or other financial intermediaries (together, “intermediaries”) related to marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems, or their making shares of the Fund and certain other iShares funds available to their customers. Such payments, which may be significant to the intermediary, are not made by the Fund. Rather, such payments are made by BFA or its Affiliates from their own resources, which come directly or indirectly in part from fees paid by the iShares funds complex. Payments of this type are sometimes referred to as revenue-sharing payments. A financial intermediary may make decisions about which investment options it recommends or makes available, or the level of services provided, to its customers based on the revenue-sharing payments it is eligible to receive. Therefore, such payments to an intermediary create conflicts of interest between the intermediary and its customers and may cause the intermediary to recommend the Fund or other iShares funds over another investment. More information regarding these payments is contained in the Fund’s SAI. Please contact your salesperson or other investment professional for more information regarding any such payments his or her firm may receive from BFA or its Affiliates.

Financial Highlights

The financial highlights table is intended to help investors understand the Fund’s financial performance since inception. Certain information reflects financial results for a single share of the Fund. The total returns in the table represent the rate that an investor would have earned (or lost) on an investment in the Fund, assuming reinvestment of all dividends and distributions. This information has been audited by PricewaterhouseCoopers LLP, whose report is included, along with the Fund’s financial statements, in the Fund’s Annual Report (available upon request).

Supplemental Information

I. Premium/Discount Information

The table that follows presents information about the differences between the daily market price on secondary markets for shares of the Fund and the Fund’s NAV. NAV is the price at which the Fund issues and redeems shares. It is calculated in accordance with the standard formula for valuing mutual fund shares. The price used to calculate market returns (“Market Price”) of the Fund generally is determined using the midpoint between the highest bid and the lowest offer on the primary securities exchange on which shares of the Fund are listed for trading, as of the time that the Fund’s NAV is calculated. The Fund’s Market Price may be at, above or below its NAV. The NAV of the Fund will fluctuate with changes in the value of its portfolio holdings. The Market Price of the Fund will fluctuate in accordance with changes in its NAV, as well as market supply and demand.

Premiums or discounts are the differences (expressed as a percentage) between the NAV and Market Price of the Fund on a given day, generally at the time the NAV is calculated. A premium is the amount that the Fund is trading above the reported NAV, expressed as a percentage of the NAV. A discount is the amount that the Fund is trading below the reported NAV, expressed as a percentage of the NAV.

The following information shows the frequency of distributions of premiums and discounts for the Fund from April 1, 2010 through September 30, 2011.

Each line in the table shows the number of trading days in which the Fund traded within the premium/discount range indicated. The number of trading days in each premium/discount range is also shown as a percentage of the total number of trading days in the period covered by the table. All data presented here represents past performance, which cannot be used to predict future results.

Premium/Discount Range
Number of Days
Percentage of Total Days
Greater than 3.0% 1 0.26%
Greater than 2.5% and Less than 3.0% 1 0.26
Greater than 2.0% and Less than 2.5% 5 1.32
Greater than 1.5% and Less than 2.0% 12 3.16

Less than -3.5% 1 0.26
   380 100.00%

II. Total Return Information

The table that follows presents information about the total returns of the Fund and the Underlying Index as of the fiscal year ended July 31, 2011.

“Average Annual Total Returns” represent the average annual change in value of an investment over the periods indicated. “Cumulative Total Returns” represent the total change in value of an investment over the period indicated.

The Fund’s NAV is the value of one share of the Fund as calculated in accordance with the standard formula for valuing mutual fund shares. The NAV return is based on the NAV of the Fund and the market return is based on the Market Price of the Fund. Market Price is determined by using the midpoint between the highest bid and the lowest offer on the primary stock exchange on which shares of the Fund are listed for trading, as of the time that the Fund’s NAV is calculated. Since shares of the Fund did not trade in the secondary market until after the Fund’s inception, for the period from inception to the first day of secondary market trading in shares of the Fund, the NAV of the Fund is used as a proxy for the Market Price to calculate market returns. Market and NAV returns assume that dividends and capital gain distributions have been reinvested in the Fund at Market Price and NAV, respectively.

An index is a statistical composite that tracks a specified financial market or sector. Unlike the Fund, the Underlying Index does not actually hold a portfolio of securities and therefore does not incur the expenses incurred by the Fund. These expenses negatively impact the performance of the Fund. Also, market returns do not include brokerage commissions that may be payable on secondary market transactions. If brokerage commissions were included, market returns would be lower. The returns shown in the following table do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption or sale of Fund shares. The investment return and principal value of shares of the Fund will vary with changes in market conditions. Shares of the Fund may be worth more or less than their original cost when they are redeemed or sold in the market. The Fund’s past performance is no guarantee of future results.

Fund Overview

iSHARES® MSCI FAR EAST FINANCIALS SECTOR INDEX FUND

Ticker: FEFN Stock Exchange: NASDAQ

Investment Objective

The iShares MSCI Far East Financials Sector Index Fund (the “Fund”) seeks investment results that correspond generally to the price and yield performance, before fees and expenses, of the MSCI Far East Financials Index (the “Underlying Index”).

Fees and Expenses

The following table describes the fees and expenses that you will incur if you own shares of the Fund. The investment advisory agreement between iShares Trust (the “Trust”) and BlackRock Fund Advisors (“BFA”) (the “Investment Advisory Agreement”) provides that BFA will pay all operating expenses of the Fund, except interest expenses, taxes, brokerage expenses, future distribution fees or expenses, and extraordinary expenses.

You may also incur usual and customary brokerage commissions when buying or selling shares of the Fund, which are not reflected in the example that follows:

Annual Fund Operating Expenses

percentage of the value of your investments)

Example. This Example is intended to help you compare the cost of owning shares of the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

1 Year
3 Years
5 Years
10 Years
$49 $154 $269 $604

Portfolio Turnover. The Fund may pay transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 9% of the average value of its portfolio.

Principal Investment Strategies

The Underlying Index is a free float-adjusted market capitalization-weighted index designed to measure the combined equity market performance of the financial sector of developed countries and regions in the Far East. Component companies include those of banks, diversified financial companies, insurance companies and real estate companies. As of September 30, 2011, the Underlying Index consisted of companies in the following countries or regions: Hong Kong, Japan and Singapore (together, the “Far East financial sector countries”). As of September 30, 2011, the Underlying Index was comprised of 82 securities.

BFA uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to “beat” the index it tracks and does not seek temporary defensive positions when markets decline or appear overvalued.

Indexing may eliminate the chance that the Fund will substantially outperform the Underlying Index but also may reduce some of the risks of active management, such as poor security selection. Indexing seeks to achieve lower costs and better after-tax performance by keeping portfolio turnover low in comparison to actively managed investment companies.

BFA uses a representative sampling indexing strategy to manage the Fund. “Representative sampling” is an indexing strategy that involves investing in a representative sample of securities that collectively has an investment profile similar to the Underlying Index. The securities selected are expected to have, in the aggregate, investment characteristics (based on factors such as market capitalization and industry weightings), fundamental characteristics (such as return variability and yield) and liquidity measures similar to those of the Underlying Index. The Fund may or may not hold all of the securities in the Underlying Index.

The Fund generally invests at least 80% of its assets in securities of the Underlying Index and in depositary receipts representing securities of the Underlying Index. The Fund may invest the remainder of its assets in securities not included in the Underlying Index, but which BFA believes will help the Fund track the Underlying Index and in other investments including futures contracts, options on futures contracts, options and swaps as well as cash and cash equivalents, including shares of money market funds advised by BFA or its affiliates.

The Fund may lend securities representing up to one-third of the value of the Fund’s total assets (including the value of the collateral received).



S-2   


Table Of Contents



The Underlying Index is sponsored by an organization (the “Index Provider”) that is independent of the Fund and BFA. The Index Provider determines the composition and relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index. The Fund’s Index Provider is MSCI Inc. (“MSCI”).

Industry Concentration Policy. The Fund will concentrate its investments (i.e., hold 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. For purposes of this limitation, securities of the U.S. government (including its agencies and instrumentalities) and repurchase agreements collateralized by U.S. government securities are not considered to be issued by members of any industry.

Summary of Principal Risks

As with any investment, you could lose all or part of your investment in the Fund, and the Fund’s performance could trail that of other investments. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund’s net asset value per share (“NAV”), trading price, yield, total return and ability to meet its investment objective.

Asset Class Risk. Securities in the Underlying Index or in the Fund’s portfolio may underperform in comparison to the general securities markets or other asset classes.

Concentration Risk. To the extent that the Fund’s investments are concentrated in a particular issuer, region, country, market, industry or asset class, the Fund may be susceptible to loss due to adverse occurrences affecting that issuer, region, country, market, industry or asset class.

Currency Risk. Because the Fund’s NAV is determined in U.S. dollars, the Fund’s NAV could decline if the currency of a non-U.S. market in which the Fund invests depreciates against the U.S. dollar.

Equity Securities Risk. Equity securities are subject to changes in value and their values may be more volatile than other asset classes.

Financial Sector Risk. Performance of companies in the financial sector may be adversely impacted by many factors, including, among others, government regulations, economic conditions, credit rating downgrades, changes in interest rates, and decreased liquidity in credit markets. This sector has experienced significant losses in the recent past, and the impact of more stringent capital requirements and of recent or future regulation on any individual financial company or on the sector as a whole cannot be predicted.

Geographic Risk. A natural or other disaster could occur in a geographic region in which the Fund invests, which could affect the economy or particular business operations of companies in the specific geographic region, causing an adverse impact on the Fund’s investments in the affected region.

Insurance Industry Risk. The insurance industry may be significantly affected by changes in interest rates, catastrophic events, price and marketing competition, the imposition of premium rate caps, or other changes in government regulation or tax law, among other factors.



S-3   


Table Of Contents



Issuer Risk. Fund performance depends on the performance of individual securities to which the Fund has exposure. Changes to the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA’s investment management strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares, losses from trading in secondary markets, periods of high volatility and disruption in the creation/redemption process of the Fund. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV.

Mid-Capitalization Companies Risk. The Fund may invest in the securities of mid-capitalization companies. Compared to large-capitalization companies, mid-capitalization companies may be less stable and more susceptible to adverse developments and their securities may be more volatile and less liquid.

Non-Diversification Risk. The Fund may invest a large percentage of its assets in securities issued by or representing a small number of issuers. As a result, the Fund’s performance may depend on the performance of a small number of issuers.

Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers are subject to the risks associated with investing in those non-U.S. markets, such as heightened risks of inflation or nationalization. The Fund may lose money due to political, economic and geographic events affecting a non-U.S. issuer or market. The Fund is specifically exposed to Asian Economic Risk.

Passive Investment Risk. The Fund is not actively managed and BFA does not attempt to take defensive positions under any market conditions, including declining markets.

Privatization Risk. Some countries in which the Fund invests have begun a process of privatizing certain entities and industries. Privatized entities may lose money or be re-nationalized.

Real Estate Investment Risk. The Fund invests in companies that invest in real estate, such as real estate investment trusts (“REITs”) or real estate holding companies, which exposes investors in the Fund to the risks of owning real estate directly, as well as to risks that relate specifically to the way in which real estate companies are organized and operated.

Reliance on Trading Partners Risk. The Fund invests in countries whose economies are heavily dependent upon trading with key partners. Any reduction in this trading may have an adverse impact on the Fund’s investments. Through its trading partners, the Fund is particularly exposed to U.S. Trading Partner Risk.

Risk of Investing in Hong Kong. The Fund’s investment in Hong Kong issuers may subject the Fund to legal, regulatory, political, currency, security, and economic risk specific to Hong

S-4   


Table Of Contents



Kong. China is Hong Kong’s largest trading partner, both in terms of exports and imports. Any changes in the Chinese economy, trade regulations or currency exchange rates or to tighten China’s control over Hong Kong may have an adverse impact on Hong Kong’s economy.

Risk of Investing in Japan. The Japanese economy may be subject to considerable degrees of economic, political and social instability, which could have a negative impact on Japanese securities.

Securities Lending Risk. The Fund may engage in securities lending. Securities lending involves the risk that the Fund may lose money because the borrower of the Fund’s loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Small-Capitalization Companies Risk. The Fund may invest in the securities of small-capitalization companies. Compared to mid- and large-capitalization companies, small-capitalization companies may be less stable and more susceptible to adverse developments and their securities may be more volatile and less liquid.

Structural Risk. The countries in which the Fund invests may be subject to considerable degrees of economic, political and social instability.

Tracking Error Risk. The performance of the Fund may diverge from that of the Underlying Index. Because the Fund employs a representative sampling strategy, the Fund may experience tracking error to a greater extent than a fund that seeks to replicate an index.

Valuation Risk. The value of the securities in the Fund’s portfolio may change on days when shareholders will not be able to purchase or sell the Fund’s shares.

Performance Information

As of the date of the Fund’s prospectus (the “Prospectus”), the Fund has been in operation for less than one full calendar year and therefore does not report its performance information.

Management

Investment Adviser. BlackRock Fund Advisors.

Portfolio Managers. Rene Casis, Diane Hsiung and Greg Savage (the “Portfolio Managers”) are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager supervises a portfolio management team. Mr. Casis has been a Portfolio Manager of the Fund since 2010. Ms. Hsiung and Mr. Savage have been Portfolio Managers of the Fund since inception.

Purchase and Sale of Fund Shares

The Fund is an exchange-traded fund (commonly referred to as an “ETF”). Individual Fund shares may only be purchased and sold on a national securities exchange through a broker-dealer. The price of Fund shares is based on market price, and because ETF shares trade at market prices rather than NAV, shares may trade at a price greater than NAV (a premium) or less than NAV (a discount). The Fund will only issue or redeem shares that have been aggregated into blocks of 50,000 shares or multiples thereof (“Creation Units”) to authorized participants who have entered into agreements with the Fund’s distributor. The Fund generally will issue or redeem Creation Units in return for a designated portfolio of securities (and an amount of cash) that the Fund specifies each day.

Tax Information

The Fund intends to make distributions that may be taxable to you as ordinary income or capital gains, unless you are investing through a tax-deferred arrangement such as a 401(k) plan or an individual retirement account (“IRA”).

Payments to Broker-Dealers and other Financial Intermediaries

If you purchase shares of the Fund through a broker-dealer or other financial intermediary (such as a bank), BFA or other related companies may pay the intermediary for marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems or other services related to the sale or promotion of the Fund. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.

More Information About the Fund

This Prospectus contains important information about investing in the Fund. Please read this Prospectus carefully before you make any investment decisions. Additional information regarding the Fund is available at www.iShares.com.

BFA is the investment adviser to the Fund. Shares of the Fund are listed for trading on The NASDAQ Stock Market (“NASDAQ”). The market price for a share of the Fund may be different from the Fund’s most recent NAV.

ETFs are funds that trade like other publicly-traded securities. The Fund is designed to track an index. Similar to shares of an index mutual fund, each share of the Fund represents a partial ownership in an underlying portfolio of securities intended to track a market index. Unlike shares of a mutual fund, which can be bought and redeemed from the issuing fund by all shareholders at a price based on NAV, shares of the Fund may be purchased or redeemed directly from the Fund at NAV solely by authorized participants. Also unlike shares of a mutual fund, shares of the Fund are listed on a national securities exchange and trade in the secondary market at market prices that change throughout the day.

The Fund invests in a particular segment of the securities markets and seeks to track the performance of a securities index that generally is not representative of the market as a whole. The Fund is designed to be used as part of broader asset allocation strategies. Accordingly, an investment in the Fund should not constitute a complete investment program.

An index is a theoretical financial calculation while the Fund is an actual investment portfolio. The performance of the Fund and the Underlying Index may vary due to transaction costs, non-U.S. currency valuations, asset valuations, corporate actions (such as mergers and spin-offs), timing variances and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions (such as diversification requirements) that apply to the Fund but not to the Underlying Index or to the use of representative sampling. “Tracking error” is the difference between the performance (return) of the Fund’s portfolio and that of the Underlying Index. BFA expects that, over time, the Fund’s tracking error will not exceed 5%. Because the Fund uses a representative sampling indexing strategy, it can be expected to have a larger tracking error than if it used a replication indexing strategy. “Replication” is an indexing strategy in which a fund invests in substantially all of the securities in its underlying index in approximately the same proportions as in the underlying index.

An investment in the Fund is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, BFA or any of its affiliates.

The Fund’s investment objective and the Underlying Index may be changed without shareholder approval.

A Further Discussion of Principal Risks

The Fund is subject to various risks, including the principal risks noted below, any of which may adversely affect the Fund’s NAV, trading price, yield, total return and ability to meet its investment objective. You could lose all or part of your investment in the Fund, and the Fund could underperform other investments.

Asian Economic Risk. Certain Asian economies have experienced over-extension of credit, currency devaluations and restrictions, high unemployment, high inflation, decreased exports and economic recessions. Economic events in any one Asian country may have a significant economic effect on the entire Asian region, as well as on major trading partners outside Asia, and any adverse event in the Asian markets may have a significant adverse effect on some or all of the financial sectors of Far East countries in which the Fund invests.

Asset Class Risk. The securities in the Underlying Index or in the Fund’s portfolio may underperform the returns of other securities or indexes that track other countries, groups of countries, regions, industries, groups of industries, markets, asset classes or sectors. Various types of securities or indexes tend to experience cycles of outperformance and underperformance in comparison to the general securities markets.

Concentration Risk. To the extent that the Fund’s portfolio reflects the Underlying Index’s concentration in the securities of a particular issuer or issuers in a particular country, group of countries, region, market, industry, group of industries, sector or asset class, the Fund may be adversely affected by the performance of those securities, may be subject to increased price volatility and may be more susceptible to adverse economic, market, political or regulatory occurrences affecting that issuer, country, group of countries, region, market, industry, group of industries, sector or asset class.

Currency Risk. Because the Fund’s NAV is determined on the basis of the U.S. dollar, investors may lose money if the currency of a non-U.S. market in which the Fund invests depreciates against the U.S. dollar, even if the local currency value of the Fund’s holdings in that market increases.

Equity Securities Risk. The Fund invests in equity securities, which are subject to changes in value that may be attributable to market perception of a particular issuer or to general stock market fluctuations that affect all issuers. Investments in equity securities may be more volatile than investments in other asset classes.

Financial Sector Risk. Companies in the financial sector of an economy are often subject to governmental regulation and, recently, government intervention and the potential for additional regulation, which may adversely affect the scope of their activities, the prices they can charge and the amount of capital they must maintain. Governmental regulation may change frequently and may have significant adverse consequences for companies in the financial sector, including effects not intended by such regulation. The impact of recent or future regulation in various countries on any individual financial company or on the sector as a whole cannot be predicted. Certain risks may impact the value of investments in the financial sector more severely than investments outside this sector, including the risks associated with companies that

operate with substantial financial leverage. Companies in the financial sector may also be adversely affected by increases in interest rates and loan losses, decreases in the availability of money or asset valuations, credit rating downgrades and adverse conditions in other related markets. Over the past few years, the deterioration of the credit markets has impacted a broad range of mortgage, asset-backed, auction rate, sovereign debt and other markets, including U.S. and non-U.S. credit and interbank money markets, thereby affecting a wide range of financial institutions and markets. This situation has created instability in the financial markets and caused certain financial companies to incur large losses. Some financial companies have experienced declines in the valuations of their assets, taken actions to raise capital (such as the issuance of debt or equity securities), or even ceased operations. Some financial companies have borrowed significant amounts of capital from governments and may face future government-imposed restrictions on their businesses or increased government intervention. These actions have caused the securities of many financial companies to decline in value. Insurance companies, in particular, may be subject to severe price competition, which may have an adverse impact on their profitability.

Geographic Risk. Some markets in which the Fund invests are located in parts of the world that have historically been prone to natural disasters, such as earthquakes, volcanoes, droughts, floods, hurricanes and tsunamis, and are economically sensitive to environmental events. Any natural or other disaster could have a significant adverse impact on the economies of these geographic areas, causing an adverse impact on the Fund’s investments in the affected region.

Insurance Industry Risk. The insurance industry is subject to extensive government regulation in some countries and can be significantly affected by changes in interest rates, general economic conditions, price and marketing competition, the imposition of premium rate caps, or other changes in government regulation or tax law. Different segments of the insurance industry can be significantly affected by mortality and morbidity rates, environmental clean-up costs and catastrophic events such as earthquakes, hurricanes and terrorist acts.

Issuer Risk. The performance of the Fund depends on the performance of individual securities to which the Fund has exposure. Any issuer of these securities may perform poorly, causing the value of its securities to decline. Poor performance may be caused by poor management decisions, competitive pressures, changes in technology, expiration of patent protection, disruptions in supply, labor problems or shortages, corporate restructurings, fraudulent disclosures or other factors. Issuers may, in times of distress or at their own discretion, decide to reduce or eliminate dividends, which may also cause their stock prices to decline.

Management Risk. The Fund may not fully replicate the Underlying Index and may hold securities not included in the Underlying Index. As a result, the Fund is subject to the risk that BFA’s investment management strategy, the implementation of which is subject to a number of constraints, may not produce the intended results.

Market Risk. The Fund could lose money due to short-term market movements and over longer periods during market downturns. Securities may decline in value due to factors affecting securities markets generally or particular industries represented in the markets. The value of a security may decline due to general market conditions,

economic trends or events that are not specifically related to the issuer of the security or to factors that affect a particular industry or industries. During a general downturn in the securities markets, multiple asset classes may be negatively affected.

Market Trading Risk

Absence of Active Market. Although shares of the Fund are listed for trading on one or more stock exchanges, there can be no assurance that an active trading market for such shares will develop or be maintained.

Risk of Secondary Listings. The Fund’s shares may be listed or traded on U.S. and non-U.S. stock exchanges other than the U.S. stock exchange where the Fund’s primary listing is maintained. There can be no assurance that the Fund’s shares will continue to trade on any such stock exchange or in any market or that the Fund’s shares will continue to meet the requirements for listing or trading on any exchange or in any market. The Fund’s shares may be less actively traded in certain markets than others, and investors are subject to the execution and settlement risks and market standards of the market where they or their broker direct their trades for execution. Certain information available to investors who trade Fund shares on a U.S. stock exchange during regular U.S. market hours may not be available to investors who trade in other markets, which may result in secondary market prices in such markets being less efficient.

Secondary Market Trading Risk. Shares of the Fund may trade in the secondary market at times when the Fund does not accept orders to purchase or redeem shares. At such times, shares may trade in the secondary market with more significant premiums or discounts than might be experienced at times when the Fund accepts purchase and redemption orders.

Secondary market trading in Fund shares may be halted by a stock exchange because of market conditions or other reasons. In addition, trading in Fund shares on a stock exchange or in any market may be subject to trading halts caused by extraordinary market volatility pursuant to “circuit breaker” rules on the stock exchange or market. There can be no assurance that the requirements necessary to maintain the listing or trading of Fund shares will continue to be met or will remain unchanged.

Shares of the Fund May Trade at Prices Other Than NAV. Shares of the Fund trade on stock exchanges at prices at, above or below their most recent NAV. The NAV of the Fund is calculated at the end of each business day and fluctuates with changes in the market value of the Fund’s holdings since the most recent calculation. The trading prices of the Fund’s shares fluctuate continuously throughout trading hours based on market supply and demand rather than NAV. The trading prices of the Fund’s shares may deviate significantly from NAV during periods of market volatility. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV. However, because shares can be created and redeemed in Creation Units at NAV (unlike shares of many closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their NAVs), BFA believes that large discounts or premiums to the NAV of the Fund are not likely to be sustained over the long-term. While the creation/redemption feature is designed to make it likely that the Fund’s shares normally will trade on stock

exchanges at prices close to the Fund’s next calculated NAV, exchange prices are not expected to correlate exactly with the Fund’s NAV due to timing reasons as well as market supply and demand factors. In addition, disruptions to creations and redemptions or extreme market volatility may result in trading prices for shares of the Fund that differ significantly from its NAV.

Costs of Buying or Selling Fund Shares. Buying or selling Fund shares on an exchange involves two types of costs that apply to all securities transactions. When buying or selling shares of the Fund through a broker, you will likely incur a brokerage commission or other charges imposed by brokers as determined by that broker. In addition, you may incur the cost of the “spread” – that is, the difference between what investors are willing to pay for Fund shares (the “bid” price) and the price at which they are willing to sell Fund shares (the “ask” price). Because of the costs inherent in buying or selling Fund shares, frequent trading may detract significantly from investment results and an investment in Fund shares may not be advisable for investors who anticipate regularly making small investments.

Mid-Capitalization Companies Risk. Many of the companies in which the Fund invests are considered mid-capitalization companies. Stock prices of mid-capitalization companies may be more volatile than those of large-capitalization companies and, therefore, the Fund’s share price may be more volatile than those of funds that invest a larger percentage of their assets in stocks issued by large-capitalization companies. Stock prices of mid-capitalization companies are also more vulnerable than those of large-capitalization companies to adverse business or economic developments, and the stocks of mid-capitalization companies may be less liquid, making it difficult for the Fund to buy and sell them. In addition, mid-capitalization companies generally have less diverse product lines than large-capitalization companies and are more susceptible to adverse developments related to their products.

Non-Diversification Risk. The Fund is classified as “non-diversified.” This means that the Fund may invest a large percentage of its assets in securities issued by or representing a small number of issuers. As a result, the Fund may be more susceptible to the risks associated with these particular issuers, or to a single economic, political or regulatory occurrence affecting these issuers.

Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers are subject to all of the risks of investing in the markets where such issuers are located, including heightened risks of inflation or nationalization and market fluctuations caused by economic and political developments. As a result of investing in non-U.S. securities, the Fund may be subject to increased risk of loss caused by any of the factors listed below:

  • Lower levels of liquidity and market efficiency;
  • Greater securities price volatility;
  • Exchange rate fluctuations and exchange controls;
  • Less availability of public information about issuers;
  • Limitations on foreign ownership of securities;
  • Imposition of withholding or other taxes;
  • Imposition of restrictions on the expatriation of the funds or other assets of the Fund;
  • Higher transaction and custody costs and delays in settlement procedures;
  • Difficulties in enforcing contractual obligations;
  • Lower levels of regulation of the securities market;
  • Weaker accounting, disclosure and reporting requirements; and
  • Legal principles related to corporate governance, directors’ fiduciary duties and liabilities and stockholders’ rights in markets in which the Fund invests may differ and/or may not be as extensive or protective as those that apply in the United States.

Passive Investment Risk. The Fund is not actively managed and may be affected by a general decline in market segments related to the Underlying Index. The Fund invests in securities included in, or representative of, the Underlying Index regardless of their investment merits. BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

Privatization Risk. Some countries in which the Fund invests have begun a process of privatizing certain entities and industries. In some instances, investors in newly privatized entities have suffered losses due to the inability of the newly privatized entities to adjust quickly to a competitive environment or changing regulatory and legal standards or, in some cases, due to re-nationalization of such privatized entities. There is no assurance that such losses will not recur.

Real Estate Investment Risk. The Fund invests in companies that invest in, develop, or operate real estate, or provide real estate related services (“Real Estate Companies”), such as REITs, real estate holding companies, or real estate management or development companies which exposes investors to the risks of owning real estate directly, as well as to risks that relate specifically to the way in which Real Estate Companies are organized and operated. Real estate is highly sensitive to general and local economic conditions and developments, and characterized by intense competition and periodic overbuilding. Since 2007, the U.S. residential and commercial real estate markets generally have experienced a decline in value, with certain regions experiencing significant losses in property values. Exposure to real estate in these regions may adversely affect Fund performance.

  • Concentration Risk. Real Estate Companies may lack diversification due to ownership of a limited number of properties and concentration in a particular geographic region or property type.
  • Equity REITs Risk. Certain REITs may make direct investments in real estate. These REITs are often referred to as “Equity REITs.” Equity REITs invest primarily in real properties and earn rental income from leasing those properties. Equity REITs may also realize gains or losses from the sale of properties. Equity REITs will be affected by conditions in the real estate rental market and by changes in the value of the properties they own. A decline in rental income may occur because of extended vacancies, limitations on rents, the failure to collect rents, or increased competition from other properties or poor management. Equity REITs also can be affected by rising interest rates. Rising interest rates may cause investors to demand a high annual yield from future distributions that, in turn, could decrease the market prices for such REITs. In addition, rising interest rates also increase the costs of obtaining financing for real estate projects. Because many real estate projects are dependent upon receiving financing, this could cause the value of the Equity REITs in which the Fund invests to decline.
  • Interest Rate Risk. Rising interest rates could result in higher costs of capital for Real Estate Companies, which could negatively impact a Real Estate Company’s ability to meet its payment obligations.
  • Leverage Risk. Real Estate Companies may use leverage (and some may be highly leveraged), which increases investment risk and the risks normally associated with debt financing, and could adversely affect a Real Estate Company’s operations and market value in periods of rising interest rates. Financial covenants related to a Real Estate Company’s leveraging may affect the ability of the Real Estate Company to operate effectively. In addition, real property may be subject to the quality of credit extended and defaults by borrowers and tenants. Leveraging may also increase repayment risk.
  • Liquidity Risk. Investing in Real Estate Companies may involve risks similar to those associated with investing in small-capitalization companies. Real Estate Company securities, like the securities of other small companies, may be more volatile than, and perform differently from, shares of large-capitalization companies. There may be less trading in Real Estate Company shares, which means that buy and sell transactions in those shares could have a magnified impact on share price, resulting in abrupt or erratic price fluctuations. In addition, real estate is relatively illiquid and, therefore, a Real Estate Company may have a limited ability to vary or liquidate its investments in properties in response to changes in economic or other conditions.
  • Operational Risk. Real Estate Companies are dependent upon management skills and may have limited financial resources. Real Estate Companies are generally not diversified and may be subject to heavy cash flow dependency, default by borrowers and self-liquidation. In addition, transactions between Real Estate Companies and their affiliates may be subject to conflicts of interest, which may adversely affect a Real Estate Company’s shareholders. A Real Estate Company may also have joint ventures in certain of its properties and, consequently, its ability to control decisions relating to such properties may be limited.
  • Property Risk. Real Estate Companies may be subject to risks relating to functional obsolescence or reduced desirability of properties; extended vacancies due to economic conditions and tenant bankruptcies; catastrophic events such as earthquakes, hurricanes, tornadoes and terrorist acts; and casualty or condemnation losses. Real estate income and values also may be greatly affected by demographic trends, such as population shifts, changing tastes and values, or increasing vacancies or declining rents resulting from legal, cultural, technological, global or local economic developments.
  • Regulatory Risk. Real estate income and values may be adversely affected by applicable domestic and foreign laws (including tax laws). Government actions, such as tax increases, zoning law changes or environmental regulations, also may have a major impact on real estate.
  • Repayment Risk. The prices of Real Estate Company securities may drop because of the failure of borrowers to repay their loans, poor management, or the inability to obtain financing either on favorable terms or at all. If the properties do not generate sufficient income to meet operating expenses, including, where applicable, debt service, ground lease payments, tenant improvements, third-party leasing commissions and other capital expenditures, the income and ability of the Real Estate Companies to make payments of interest and principal on their loans will be adversely affected. Many Real Estate Companies utilize leverage, which increases investment risk and could adversely affect a company’s operations and market value in periods of rising interest rates.

Reliance on Trading Partners Risk. The economies of the Far East financial sector countries are dependent on each other and on the United States as key trading partners. Reduction in spending on the products and services of the Far East financial sector countries by any of their key trading partners, institution of tariffs or other trade barriers or a slowdown in the economies of any of their key trading partners may cause an adverse impact on the economies of the Far East financial sector countries.


U.S. Trading Partners Risk. The United States is a significant, and in some cases the most significant, trading partner of or foreign investor in certain Far East financial sector countries and the economies of these countries may be particularly affected by changes in the U.S. economy. Decreasing U.S. imports, new trade regulations, changes in the U.S. dollar exchange rate or a recession in the United States may have a material adverse effect on the economies of Far East financial sector countries.

Risk of Investing in Hong Kong. The Fund’s investment in Hong Kong issuers may subject the Fund to legal, regulatory, political, currency, security, and economic risk specific to Hong Kong. China is Hong Kong’s largest trading partner, both in terms of exports and imports. Any changes in the Chinese economy, trade regulations or currency exchange rates may have an adverse impact on Hong Kong’s economy.

  • Political and Social Risk. Hong Kong reverted to Chinese sovereignty on July 1, 1997 as a Special Administrative Region (SAR) of the People’s Republic of China under the principle of “one country, two systems.” Although China is obligated to maintain the current capitalist economic and social system of Hong Kong through June 30, 2047, the continuation of economic and social freedoms enjoyed in Hong Kong is dependent on the government of China. Any attempt by China to tighten its control over Hong Kong’s political, economic or social policies may result in an adverse effect on Hong Kong’s economy.
  • Economic Risk. The economy of Hong Kong is closely tied to the economy of China. The Chinese economy has grown rapidly during the past several years and there is no assurance that this growth rate will be maintained. China may experience substantial rates of inflation or economic recessions, causing a negative effect on the economy and securities market. Delays in enterprise restructuring, slow development of well-functioning financial markets and widespread corruption have also hindered performance of the Chinese economy and China continues to receive substantial pressure from trading partners to liberalize official currency exchange rates. Any downturn of the Chinese economy may have an adverse effect on Hong Kong’s economy.

Risk of Investing in Japan. Japan may be subject to political, economic, nuclear, and labor risks. Any of these risks, individually or in the aggregate, can impact an investment made in Japan.

  • Political Risk. Historically, Japan has had unpredictable national politics and may experience frequent political turnover. Future political developments may lead to changes in policy that might adversely affect the Fund’s investments.
  • Large Government Debt Risk. The Japanese economy faces several concerns, including a financial system with large levels of nonperforming loans, over-leveraged corporate balance sheets, extensive cross-ownership by major corporations, a changing corporate governance structure, and large government deficits. These issues may cause a slowdown of the Japanese economy.
  • Currency Risk. The Japanese yen has fluctuated widely at times and any increase in its value may cause a decline in exports that could weaken the economy.
  • Nuclear Risk. The nuclear power plant catastrophe in Japan in March of 2011 may have short-term and long-term effects on the nuclear energy industry, the extent of which are currently unknown.
  • Labor Risk. Japan has an aging workforce. It is a labor market that is undergoing fundamental structural changes, as traditional lifetime employment clashes with the need for increased labor mobility, which may adversely affect Japan’s economic competitiveness.
  • Geographic Risk. Natural disasters, such as earthquakes, could occur in Japan or surrounding areas and could negatively affect the Japanese economy, and, in turn, could negatively affect the Fund.

Securities Lending Risk. The Fund may engage in securities lending. Securities lending involves the risk that the Fund may lose money because the borrower of the Fund’s loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for the loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Small-Capitalization Companies Risk. Many of the companies in which the Fund invests are considered small-capitalization companies. Stock prices of small-capitalization companies may be more volatile than those of larger companies and, therefore, the Fund’s share price may be more volatile than those of funds that invest a larger percentage of their assets in stocks issued by mid- or large-capitalization companies. Stock prices of small-capitalization companies are generally more vulnerable than those of mid- or large-capitalization companies to adverse business and economic developments. Securities of small-capitalization companies may be thinly traded, making it difficult for the Fund to buy and sell them. In addition, small-capitalization companies are typically less financially stable than larger, more established companies and may depend on a small number of essential personnel, making them more vulnerable to loss of personnel. Small-capitalization companies also normally have less diverse product lines than mid- or large-capitalization companies and are more susceptible to adverse developments concerning their products.

Structural Risk. Certain political, economic, legal and currency risks have contributed to a high degree of price volatility in the equity markets of the countries in which the Fund invests and could adversely affect investments in the Fund:

Political and Social Risk. Disparities of wealth, the pace and success of democratization and ethnic, religious and racial disaffection, among other factors, have led to social unrest, violence and labor unrest in some countries in which the Fund invests. Unanticipated or sudden political or social developments may result in sudden and significant investment losses.

Economic Risk. Some countries in which the Fund invests may experience economic instability, including instability resulting from substantial rates of inflation or significant devaluations of their currency, or economic recessions causing a negative effect on the economies and securities markets of their economies. Some of these countries may also impose restrictions on the exchange or export of currency or adverse currency exchange rates and may be characterized by a lack of available currency hedging instruments.

Expropriation and/or Nationalization Risk. Investments in certain countries in which the Fund invests may be subject to loss due to expropriation or nationalization of assets and property or the imposition of restrictions on foreign investments and repatriation of capital.

Large Government Debt Risk. Chronic structural public sector deficits in some countries in which the Fund invests may adversely impact investments in the Fund.

Tracking Error Risk. Imperfect correlation between the Fund’s portfolio securities and those in the Underlying Index, rounding of prices, changes to the Underlying Index and regulatory requirements may cause tracking error, which is the divergence of the Fund’s performance from that of the Underlying Index. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Underlying Index does not. Because the Fund employs a representative sampling strategy, the Fund may experience tracking error to a greater extent than a fund that seeks to replicate an index.

Valuation Risk. Because non-U.S. exchanges may be open on days when the Fund does not price its shares, the value of the securities in the Fund’s portfolio may change on days when shareholders will not be able to purchase or sell the Fund’s shares. In addition, for purposes of calculating the Fund’s NAV, the value of assets denominated in non-U.S. currencies is converted into U.S. dollars using exchange rates deemed appropriate by BFA. This conversion may result in a difference between the prices used to calculate the Fund’s NAV and the prices used by the Underlying Index, which, in turn, could result in a difference between the Fund’s performance and the performance of the Underlying Index.

Portfolio Holdings Information

A description of the Trust’s policies and procedures with respect to the disclosure of the Fund’s portfolio securities is available in the Fund’s Statement of Additional Information (“SAI”). The top holdings of the Fund can be found at www.iShares.com.

Fund fact sheets provide information regarding the Fund’s top holdings and may be requested by calling 1-800-iShares (1-800-474-2737).

Management

Investment Adviser. As investment adviser, BFA has overall responsibility for the general management and administration of the Trust. BFA provides an investment program for the Fund and manages the investment of the Fund’s assets. In managing the Fund, BFA may draw upon the research and expertise of its asset management affiliates with respect to certain portfolio securities. In seeking to achieve the Fund’s investment objective, BFA uses teams of portfolio managers, investment strategists and other investment specialists. This team approach brings together many disciplines and leverages BFA’s extensive resources.

Pursuant to the Investment Advisory Agreement between BFA and the Trust (entered into on behalf of the Fund), BFA is responsible for substantially all expenses of the Fund, except interest expenses, taxes, brokerage expenses, future distribution fees or expenses and extraordinary expenses.

For its investment advisory services to the Fund, BFA is entitled to receive a management fee from the Fund based on a percentage of the Fund’s average daily net assets, at the annual rate of 0.48%.

BFA is located at 400 Howard Street, San Francisco, CA 94105. It is a wholly owned subsidiary of BTC, which in turn is indirectly wholly-owned by BlackRock, Inc. (“BlackRock”). As of September 30, 2011, BTC and its affiliates, including BFA and BlackRock, provided investment advisory services for assets in excess of $3.35 trillion. BFA, BTC, BlackRock Execution Services, BlackRock and their affiliates deal, trade and invest for their own accounts in the types of securities in which the Fund may also invest.

A discussion regarding the basis for the Trust’s Board of Trustees’ (the “Board”) approval of the Investment Advisory Agreement with BFA is available in the Fund’s annual report for the period ended July 31.

Portfolio Managers. Rene Casis, Diane Hsiung and Greg Savage are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager is responsible for various functions related to portfolio management, including, but not limited to, investing cash inflows, coordinating with members of his or her portfolio management team to focus on certain asset classes, implementing investment strategy, researching and reviewing investment strategy and overseeing members of his or her portfolio management team that have more limited responsibilities.

Rene Casis has been employed by BFA (formerly, Barclays Global Fund Advisors (“BGFA”)) and BTC (formerly, Barclays Global Investors, N.A. (“BGI”)) as a senior portfolio manager since 2009. From 2005 to 2009, Mr. Casis was a trader at Barclays Capital. Prior to that, Mr. Casis was a portfolio manager from 2000 to 2005 for BGFA and BGI. Mr. Casis has been a Portfolio Manager of the Fund since 2010.

Diane Hsiung has been employed by BFA and BTC as a senior portfolio manager since 2007. Prior to that, Ms. Hsiung was a portfolio manager from 2002 to 2006 for BGFA and BGI. Ms. Hsiung has been a Portfolio Manager of the Fund since inception.

Greg Savage has been employed by BFA and BTC as a senior portfolio manager since 2006. Prior to that, Mr. Savage was a portfolio manager from 2001 to 2006 for BGFA and BGI. Mr. Savage has been a Portfolio Manager of the Fund since inception.

The Fund’s SAI provides additional information about the Portfolio Managers’ compensation, other accounts managed by the Portfolio Managers and the Portfolio Managers’ ownership (if any) of shares in the Fund.

Administrator, Custodian and Transfer Agent. State Street Bank and Trust Company (“State Street”) is the administrator, custodian and transfer agent for the Fund.

Conflicts of Interest. BFA wants you to know that there are certain entities with which BFA has relationships that may give rise to conflicts of interest, or the appearance of conflicts of interest. These entities include the following: BFA’s affiliates (including BlackRock and The PNC Financial Services Group, Inc., and each of their affiliates, directors, partners, trustees, managing members, officers and employees (collectively, the “Affiliates”)) and BlackRock’s significant shareholder, Barclays Bank PLC and its affiliates, including Barclays PLC (each, an “Entity” and together, the “Entities”).

The activities of BFA, the Affiliates and the Entities in the management of, or their interest in, their own accounts and other accounts they manage, may present conflicts of interest that could disadvantage the Fund and its shareholders. BFA and its Affiliates or the Entities provide investment management services to other funds and discretionary managed accounts that may follow an investment program similar to that of the Fund. BFA, its Affiliates and the Entities are involved worldwide with a broad spectrum of financial services and asset management activities and may engage in the ordinary course of business in activities in which their interests or the interests of their clients may conflict with those of the Fund. BFA, one or more of the Affiliates or the Entities acts, or may act, as an investor, investment banker, research provider, investment manager, financier, underwriter, advisor, market maker, trader, prime broker, lender, agent or principal, and have other direct and indirect interests, in securities, currencies and other instruments in which the Fund may directly or indirectly invest. Thus, it is likely that the Fund will have multiple business relationships with and will invest in, engage in transactions with, make voting decisions with respect to, or obtain services from, entities for which BFA, an Affiliate or an Entity performs or seeks to perform investment banking or other services.

BFA or one or more Affiliates or Entities may engage in proprietary trading and advise accounts and funds that have investment objectives similar to those of the Fund and/or that engage in and compete for transactions in the same types of securities, currencies and other instruments as the Fund, including in securities issued by other open-end and closed-end investment management companies, including investment companies that are affiliated with the Fund and BFA, to the extent permitted under the Investment Company Act of 1940, as amended (the “1940 Act”). The trading activities of BFA, these Affiliates and Entities are carried out without reference to positions held directly or indirectly by the Fund and may result in BFA, an Affiliate or an Entity having positions that are adverse to those of the Fund.

No Affiliate or Entity is under any obligation to share any investment opportunity, idea or strategy with the Fund. As a result, an Affiliate or an Entity may compete with the Fund for appropriate investment opportunities. As a result of this and several other factors, the results of the Fund’s investment activities may differ from those of an Affiliate or an Entity and of other accounts managed by an Affiliate or an Entity, and it is possible that the Fund could sustain losses during periods in which one or more Affiliates or Entities and other accounts achieve profits on their trading for proprietary or other accounts. The opposite result is also possible.

The Fund may, from time to time, enter into transactions in which BFA or an Affiliate’s or an Entity’s clients have an interest adverse to the Fund. Furthermore, transactions undertaken by Affiliate-advised clients may adversely impact the Fund. Transactions by one or more Affiliate- or Entity-advised clients or BFA may have the effect of diluting or otherwise disadvantaging the values, prices or investment strategies of the Fund.

An Entity may maintain securities indices as part of its product offerings. Index-based funds seek to track the performance of securities indices and may use the name of the index in the fund name. Index providers, including the Entities, may be paid licensing fees for use of their indices or index names. Entities will not be obligated to license their indices to BFA and its Affiliates, and BFA and its Affiliates will not be assured that the terms of any index licensing agreement with the Entities will be as favorable as those terms offered to other index licensees.

The Fund’s activities may be limited because of regulatory restrictions applicable to one or more Affiliates or Entities, and/or their internal policies designed to comply with such restrictions. In addition, the Fund may invest in securities of companies with which an Affiliate or an Entity has or is trying to develop investment banking relationships or in which an Affiliate or an Entity has significant debt or equity investments. The Fund also may invest in securities of companies for which an Affiliate or an Entity provides or may some day provide research coverage. An Affiliate or an Entity may have business relationships with and purchase or distribute or sell services or products from or to distributors, consultants or others who recommend the Fund or who engage in transactions with or for the Fund, and may receive compensation for such services. The Fund may also make brokerage and other payments to Affiliates or Entities in connection with the Fund’s portfolio investment transactions.

Pursuant to a securities lending program approved by the Board, the Fund has retained an Affiliate of BFA to serve as the securities lending agent for the Fund to the extent that the Fund participates in the securities lending program. For these services, the lending agent may receive a fee from the Fund, including a fee based on the returns earned on the Fund’s investment of the cash received as collateral for any loaned securities. In addition, one or more Affiliates may be among the entities to which the Fund may lend its portfolio securities under the securities lending program.

The activities of BFA, the Affiliates or Entities may give rise to other conflicts of interest that could disadvantage the Fund and its shareholders. BFA has adopted policies and procedures designed to address these potential conflicts of interest. See the Fund’s SAI for further information.

Shareholder Information

Additional shareholder information, including how to buy and sell shares of the Fund, is available free of charge by calling toll-free: 1-800-iShares (1-800-474-2737) or visiting our website at www.iShares.com.

Buying and Selling Shares. Shares of the Fund may be acquired or redeemed directly from the Fund only in Creation Units or multiples thereof, as discussed in the Creations and Redemptions section of this Prospectus. Only an Authorized Participant (as defined in the Creations and Redemptions section) may engage in creation or redemption transactions directly with the Fund. Once created, shares of the Fund generally trade in the secondary market in amounts less than a Creation Unit.

Shares of the Fund are listed on a national securities exchange for trading during the trading day. Shares can be bought and sold throughout the trading day like shares of other publicly-traded companies. The Trust does not impose any minimum investment for shares of the Fund purchased on an exchange. The Fund’s shares trade under the trading symbol “FEFN.”

Buying or selling Fund shares on an exchange involves two types of costs that may apply to all securities transactions. When buying or selling shares of the Fund through a broker, you will likely incur a brokerage commission or other charges determined by your broker. The commission is frequently a fixed amount and may be a significant proportional cost for investors seeking to buy or sell small amounts of shares. In addition, you may incur the cost of the “spread” – that is, any difference between the bid price and the ask price. The spread varies over time for shares of the Fund based on its trading volume and market liquidity, and is generally lower if the Fund has a lot of trading volume and market liquidity, and higher if the Fund has little trading volume and market liquidity.

The Board has adopted a policy of not monitoring for frequent purchases and redemptions of Fund shares (“frequent trading”) that appear to attempt to take advantage of a potential arbitrage opportunity presented by a lag between a change in the value of the Fund’s portfolio securities after the close of the primary markets for the Fund’s portfolio securities and the reflection of that change in the Fund’s NAV (“market timing”), because the Fund generally sells and redeems its shares directly through transactions that are in-kind and/or for cash, subject to the conditions described below under Creations and Redemptions. The Board has not adopted a policy of monitoring for other frequent trading activity because shares of the Fund are listed for trading on a national securities exchange.

The national securities exchange on which the Fund’s shares are listed is open for trading Monday through Friday and is closed on weekends and the following holidays: New Year’s Day, Martin Luther King, Jr. Day, Presidents’ Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day. The Fund’s primary listing exchange is NASDAQ.

Section 12(d)(1) of the 1940 Act restricts investments by investment companies in the securities of other investment companies. Registered investment companies are permitted to invest in the Fund beyond the limits set forth in Section 12(d)(1), subject to certain terms and conditions set forth in SEC rules or in an SEC exemptive order

issued to the Trust. In order for a registered investment company to invest in shares of the Fund beyond the limitations of Section 12(d)(1) pursuant to the exemptive relief obtained by the Trust, the registered investment company must enter into an agreement with the Trust.

Book Entry. Shares of the Fund are held in book-entry form, which means that no stock certificates are issued. The Depository Trust Company (“DTC”) or its nominee is the record owner of all outstanding shares of the Fund and is recognized as the owner of all shares for all purposes.

Investors owning shares of the Fund are beneficial owners as shown on the records of DTC or its participants. DTC serves as the securities depository for shares of the Fund. DTC participants include securities brokers and dealers, banks, trust companies, clearing corporations and other institutions that directly or indirectly maintain a custodial relationship with DTC. As a beneficial owner of shares, you are not entitled to receive physical delivery of stock certificates or to have shares registered in your name, and you are not considered a registered owner of shares. Therefore, to exercise any right as an owner of shares, you must rely upon the procedures of DTC and its participants. These procedures are the same as those that apply to any other securities that you hold in book-entry or “street name” form.

Share Prices. The trading prices of the Fund’s shares in the secondary market generally differ from the Fund’s daily NAV and are affected by market forces such as supply and demand, economic conditions and other factors. Information regarding the intraday value of shares of the Fund, also known as the “indicative optimized portfolio value” (“IOPV”), is disseminated every 15 seconds throughout the trading day by the national securities exchange on which the Fund’s shares are listed or by market data vendors or other information providers. The IOPV is based on the current market value of the securities and/or cash required to be deposited in exchange for a Creation Unit. The IOPV does not necessarily reflect the precise composition of the current portfolio of securities held by the Fund at a particular point in time or the best possible valuation of the current portfolio. Therefore, the IOPV should not be viewed as a “real-time” update of the Fund’s NAV, which is computed only once a day. The IOPV is generally determined by using both current market quotations and/or price quotations obtained from broker-dealers that may trade in the portfolio securities held by the Fund. The quotations of certain Fund holdings may not be updated during U.S. trading hours if such holdings do not trade in the United States. The Fund is not involved in, or responsible for, the calculation or dissemination of the IOPV and makes no representation or warranty as to its accuracy.

Determination of Net Asset Value. The NAV of the Fund normally is determined once daily Monday through Friday, generally as of the regularly scheduled close of business of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m., Eastern time) on each day that the NYSE is open for trading, based on prices at the time of closing provided that (a) any Fund assets or liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers (as detailed below) and (b) U.S. fixed income assets may be valued as of the announced closing time for trading in fixed income instruments in a particular market or exchange. The NAV

of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets held by the Fund, and its liabilities, are determined pursuant to valuation policies and procedures approved by the Board. The Fund’s assets and liabilities are valued primarily on the basis of market quotations.

Equity investments are valued at market value, which is generally determined using the last reported official closing price or last trading price on the exchange or market on which the security is primarily traded at the time of valuation.

The Fund invests in foreign securities. Foreign currency exchange rates are generally determined as of 4:00 p.m., London time. Foreign securities owned by the Fund may trade on weekends or other days when the Fund does not price its shares. As a result, the Fund’s NAV may change on days when Authorized Participants will not be able to purchase or redeem Fund shares.

Generally, trading in foreign securities, U.S. government securities, money market instruments and certain fixed-income securities is substantially completed each day at various times prior to the close of business on the NYSE. The values of such securities used in computing the NAV of the Fund are determined as of such times.

When market quotations are not readily available or are believed by BFA to be unreliable, the Fund’s investments are valued at fair value. Fair value determinations are made by BFA in accordance with policies and procedures approved by the Fund’s Board. BFA may conclude that a market quotation is not readily available or is unreliable if a security or other asset or liability does not have a price source due to its lack of liquidity, if a market quotation differs significantly from recent price quotations or otherwise no longer appears to reflect fair value, where the security or other asset or liability is thinly traded, or where there is a significant event subsequent to the most recent market quotation. A “significant event” is an event that, in the judgment of BFA, is likely to cause a material change to the closing market price of the asset or liability held by the Fund. Foreign securities whose values are affected by volatility that occurs in U.S. markets on a trading day after the close of foreign securities markets may be fair valued.

Fair value represents a good faith approximation of the value of an asset or liability. The fair value of an asset or liability held by the Fund is the amount the Fund might reasonably expect to receive from the current sale of that asset or the cost to extinguish that liability in an arm’s-length transaction. Valuing the Fund’s investments using fair value pricing will result in prices that may differ from current market valuations and that may not be the price at which those investments could have been sold during the period in which the particular fair values were used. Use of fair value prices and certain current market valuations could result in a difference between the prices used to calculate the Fund’s NAV and the prices used by the Underlying Index, which, in turn, could result in a difference between the Fund’s performance and the performance of the Underlying Index.

The value of assets or liabilities denominated in non-U.S. currencies will be converted into U.S. dollars using exchange rates deemed appropriate by BFA as investment

adviser. Use of a rate different from the rate used by the Index Provider may adversely affect the Fund’s ability to track the Underlying Index.

Dividends and Distributions

General Policies. Dividends from net investment income, if any, generally are declared and paid semi-annually by the Fund. Distributions of net realized securities gains, if any, generally are declared and paid once a year, but the Trust may make distributions on a more frequent basis for the Fund. The Trust reserves the right to declare special distributions if, in its reasonable discretion, such action is necessary or advisable to preserve its status as a regulated investment company (“RIC”) or to avoid imposition of income or excise taxes on undistributed income or realized gains.

Dividends and other distributions on shares of the Fund are distributed on a pro rata basis to beneficial owners of such shares. Dividend payments are made through DTC participants and indirect participants to beneficial owners then of record with proceeds received from the Fund.

Dividend Reinvestment Service. No dividend reinvestment service is provided by the Trust. Broker-dealers may make available the DTC book-entry Dividend Reinvestment Service for use by beneficial owners of the Fund for reinvestment of their dividend distributions. Beneficial owners should contact their broker to determine the availability and costs of the service and the details of participation therein. Brokers may require beneficial owners to adhere to specific procedures and timetables. If this service is available and used, dividend distributions of both income and realized gains will be automatically reinvested in additional whole shares of the Fund purchased in the secondary market.

Taxes. As with any investment, you should consider how your investment in shares of the Fund will be taxed. The tax information in this Prospectus is provided as general information, based on current law. You should consult your own tax professional about the tax consequences of an investment in shares of the Fund.

Unless your investment in Fund shares is made through a tax-exempt entity or tax-deferred retirement account, such as an IRA, you need to be aware of the possible tax consequences when the Fund makes distributions or you sell Fund shares.

Taxes on Distributions. Distributions from the Fund’s net investment income (other than qualified dividend income), including distributions of income from securities lending and distributions out of the Fund’s net short-term capital gains, if any, are taxable to you as ordinary income. Distributions by the Fund of net long-term capital gains in excess of net short-term capital losses (capital gain dividends) are taxable to you as long-term capital gains, generally at a 15% tax rate (0% at certain income levels), regardless of how long you have held the Fund’s shares. Distributions by the Fund that qualify as qualified dividend income are taxable to you at long-term capital gain rates for taxable years beginning on or before December 31, 2012. The 15% and 0% tax rates expire for taxable years beginning after December 31, 2012. Maximum long-term capital gain income tax rates are scheduled to rise to 20% in 2013. Beginning in 2013, a 3.8% U.S. federal Medicare contribution tax will be imposed on “net investment income,” including interest, dividends, and capital gains, of U.S.

individuals with income exceeding $200,000 (or $250,000 if married and filing jointly), and of estates and trusts.

Dividends will be qualified dividend income to you if they are attributable to qualified dividend income received by the Fund. Generally, qualified dividend income includes dividend income from taxable U.S. corporations and qualified non-U.S. corporations, provided that the Fund satisfies certain holding period requirements in respect of the stock of such corporations and has not hedged its position in the stock in certain ways. Substitute dividends received by the Fund with respect to dividends paid on securities lent out will not be qualified dividend income. For this purpose, a qualified non-U.S. corporation means any non-U.S. corporation that is eligible for benefits under a comprehensive income tax treaty with the United States, which includes an exchange of information program or if the stock with respect to which the dividend was paid is readily tradable on an established United States securities market. The term excludes a corporation that is a passive foreign investment company.

Dividends received by the Fund from a REIT or another RIC generally are qualified dividend income only to the extent the dividend distributions are made out of qualified dividend income received by such REIT or RIC. It is expected that dividends received by the Fund from a REIT and distributed to a shareholder generally will be taxable to the shareholder as ordinary income.

For a dividend to be treated as qualified dividend income, the dividend must be received with respect to a share of stock held without being hedged by the Fund, and with respect to a share of the Fund held without being hedged by you, for 61 days during the 121-day period beginning at the date which is 60 days before the date on which such share becomes ex-dividend with respect to such dividend or, in the case of certain preferred stock, 91 days during the 181-day period beginning 90 days before such date.

If your Fund shares are loaned out pursuant to a securities lending arrangement, you may lose the ability to use foreign tax credits passed through by the Fund or to treat Fund dividends paid while the shares are held by the borrower as qualified dividend income.

In general, your distributions are subject to U.S. federal income tax for the year when they are paid. Certain distributions paid in January, however, may be treated as paid on December 31 of the prior year.

If the Fund’s distributions exceed current and accumulated earnings and profits, all or a portion of the distributions made in the taxable year may be recharacterized as a return of capital to shareholders. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and result in a higher capital gain or lower capital loss when those shares on which the distribution was received are sold. Once a shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain, if the shareholder holds shares of the Fund as capital assets.

If you are neither a resident nor a citizen of the United States or if you are a non-U.S. entity, the Fund’s ordinary income dividends (which include distributions of net short-term capital gains) will generally be subject to a 30% U.S. withholding tax, unless a lower treaty rate applies, provided that withholding tax will generally not apply to any

gain or income realized by a non-U.S. shareholder in respect of any distributions of long-term capital gains or upon the sale or other disposition of shares of the Fund.

A 30% withholding tax will be imposed on dividends paid after December 31, 2013, and redemption proceeds paid after December 31, 2014, to (i) foreign financial institutions including non-U.S. investment funds unless they agree to collect and disclose to the Internal Revenue Service (“IRS”) information regarding their direct and indirect U.S. account holders and (ii) certain other foreign entities, unless they certify certain information regarding their direct and indirect U.S. owners. To avoid withholding, foreign financial institutions will need to enter into agreements with the IRS that state that they will provide the IRS information, including the name, address and taxpayer identification number of direct and indirect U.S. account holders, comply with due diligence procedures with respect to the identification of U.S. accounts, report to the IRS certain information with respect to U.S. accounts maintained, agree to withhold tax on certain payments made to non-compliant foreign financial institutions or to account holders who fail to provide the required information, and determine certain other information as to their account holders. Other foreign entities will need to provide the name, address, and taxpayer identification number of each substantial U.S. owner or certifications of no substantial U.S. ownership unless certain exceptions apply.

Dividends, interest and capital gains earned by the Fund with respect to non-U.S. securities may give rise to withholding and other taxes imposed by non-U.S. countries. Tax conventions between certain countries and the United States may reduce or eliminate such taxes. If more than 50% of the total assets of the Fund at the close of a year consists of non-U.S. stocks or securities, the Fund may “pass through” to you certain non-U.S. income taxes (including withholding taxes) paid by the Fund. This means that you would be considered to have received as an additional dividend your share of such non-U.S. taxes, but you may be entitled to either a corresponding tax deduction in calculating your taxable income, or, subject to certain limitations, a credit in calculating your U.S. federal income tax.

For purposes of foreign tax credits for U.S. shareholders of the Fund, foreign capital gains taxes may not produce associated foreign source income, thereby limiting a U.S. person’s ability to use such credits.

If you are a resident or a citizen of the United States, by law, back-up withholding will apply to your distributions and proceeds if you have not provided a taxpayer identification number or social security number and made other required certifications.

Taxes When Shares are Sold. Currently, any capital gain or loss realized upon a sale of Fund shares is generally treated as a long-term gain or loss if the shares have been held for more than one year. Any capital gain or loss realized upon a sale of Fund shares held for one year or less is generally treated as short-term gain or loss, except that any capital loss on the sale of shares held for six months or less is treated as long-term capital loss to the extent that capital gain dividends were paid with respect to such shares. Beginning in 2013, any such capital gains, including from sales of Fund shares or from capital gain dividends, will be included in “net investment income” for purposes of the 3.8% U.S. federal Medicare contribution tax mentioned above.

The foregoing discussion summarizes some of the consequences under current U.S. federal tax law of an investment in the Fund. It is not a substitute for personal tax advice. You may also be subject to state and local taxation on Fund distributions and sales of shares. Consult your personal tax adviser about the potential tax consequences of an investment in shares of the Fund under all applicable tax laws.

Creations and Redemptions. Prior to trading in the secondary market, shares of the Fund are “created” at NAV by market makers, large investors and institutions only in block-size Creation Units of 50,000 shares or multiples thereof. Each “creator” or “Authorized Participant” enters into an authorized participant agreement with the Fund’s distributor, SEI Investments Distribution Co. (the “Distributor”). Only an Authorized Participant may create or redeem Creation Units directly with the Fund. A creation transaction, which is subject to acceptance by the transfer agent, generally takes place when an Authorized Participant deposits into the Fund a designated portfolio of securities and a specified amount of cash approximating the holdings of the Fund in exchange for a specified number of Creation Units. To the extent practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund.

Similarly, shares can be redeemed only in Creation Units, generally for a designated portfolio of securities and a specified amount of cash held by the Fund (“Fund Securities”). Except when aggregated in Creation Units, shares are not redeemable by the Fund. The prices at which creations and redemptions occur are based on the next calculation of NAV after an order is received in a form described in the authorized participant agreement.

The Fund intends to comply with the U.S. federal securities laws in accepting securities for deposit and satisfying redemptions with redemption securities by, among other means, assuring that any securities accepted for deposit and any securities used to satisfy redemption requests will be sold in transactions that would be exempt from registration under the Securities Act of 1933, as amended (the “1933 Act”). Further, an Authorized Participant that is not a “qualified institutional buyer,” as such term is defined under Rule 144A of the 1933 Act, will not be able to receive Fund Securities that are restricted securities eligible for resale under Rule 144A.

Creations and redemptions must be made through a firm that is either a member of the Continuous Net Settlement System of the National Securities Clearing Corporation or a DTC participant and has executed an agreement with the Distributor with respect to creations and redemptions of Creation Unit aggregations. Information about the procedures regarding creation and redemption of Creation Units (including the cut-off times for receipt of creation and redemption orders) is included in the Fund’s SAI.

Because new shares may be created and issued on an ongoing basis, at any point during the life of the Fund a “distribution,” as such term is used in the 1933 Act, may be occurring. Broker-dealers and other persons are cautioned that some activities on their part may, depending on the circumstances, result in their being deemed participants in a distribution in a manner that could render them statutory underwriters and subject to the prospectus delivery and liability provisions of the 1933 Act. Any determination of whether one is an underwriter must take into account all the relevant facts and circumstances of each particular case.

Broker-dealers should also note that dealers who are not “underwriters” but are participating in a distribution (as contrasted to ordinary secondary transactions), and thus dealing with shares that are part of an “unsold allotment” within the meaning of Section 4(3)(C) of the 1933 Act, would be unable to take advantage of the prospectus delivery exemption provided by Section 4(3) of the 1933 Act. For delivery of prospectuses to exchange members, the prospectus delivery mechanism of Rule 153 under the 1933 Act is available only with respect to transactions on a national securities exchange.

Costs Associated with Creations and Redemptions. Authorized Participants are charged standard creation and redemption transaction fees to offset transfer and other transaction costs associated with the issuance and redemption of Creation Units. The standard creation and redemption transaction fees are set forth in the table below. The standard creation transaction fee is charged to the Authorized Participant on the day such Authorized Participant creates a Creation Unit, and is the same regardless of the number of Creation Units purchased by the Authorized Participant on the applicable business day. Similarly, the standard redemption transaction fee is charged to the Authorized Participant on the day such Authorized Participant redeems a Creation Unit, and is the same regardless of the number of Creation Units redeemed by the Authorized Participant on the applicable business day. Creations and redemptions for cash (when cash creations and redemptions (in whole or in part) are available or specified) are also subject to an additional charge (up to the maximum amounts shown in the table below). This charge is intended to compensate for brokerage, tax, foreign exchange, execution, market impact and other costs and expenses related to cash transactions. Investors who use the services of a broker or other financial intermediary may pay fees for such services.

The following table shows, as of September 30, 2011, the approximate value of one Creation Unit, standard fees and maximum additional charges for creations and redemptions (as described above):

Householding. Householding is an option available to certain Fund investors. Householding is a method of delivery, based on the preference of the individual investor, in which a single copy of certain shareholder documents can be delivered to investors who share the same address, even if their accounts are registered under different names. Please contact your broker-dealer if you are interested in enrolling in householding and receiving a single copy of prospectuses and other shareholder documents, or if you are currently enrolled in householding and wish to change your householding status.

Distribution

The Distributor distributes Creation Units for the Fund on an agency basis. The Distributor does not maintain a secondary market in shares of the Fund. The Distributor has no role in determining the policies of the Fund or the securities that are purchased or sold by the Fund. The Distributor’s principal address is One Freedom Valley Drive, Oaks, PA 19456.

In addition, BFA or its Affiliates make payments to broker-dealers, banks or other financial intermediaries (together, “intermediaries”) related to marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems, or their making shares of the Fund and certain other iShares funds available to their customers. Such payments, which may be significant to the intermediary, are not made by the Fund. Rather, such payments are made by BFA or its Affiliates from their own resources, which come directly or indirectly in part from fees paid by the iShares funds complex. Payments of this type are sometimes referred to as revenue-sharing payments. A financial intermediary may make decisions about which investment options it recommends or makes available, or the level of services provided, to its customers based on the revenue-sharing payments it is eligible to receive. Therefore, such payments to an intermediary create conflicts of interest between the intermediary and its customers and may cause the intermediary to recommend the Fund or other iShares funds over another investment. More information regarding these payments is contained in the Fund’s SAI. Please contact your salesperson or other investment professional for more information regarding any such payments his or her firm may receive from BFA or its Affiliates.

Financial Highlights

The financial highlights table is intended to help investors understand the Fund’s financial performance since inception. Certain information reflects financial results for a single share of the Fund. The total returns in the table represent the rate that an investor would have earned (or lost) on an investment in the Fund, assuming reinvestment of all dividends and distributions. This information has been audited by PricewaterhouseCoopers LLP, whose report is included, along with the Fund’s financial statements, in the Fund’s Annual Report (available upon request).

Supplemental Information

I. Premium/Discount Information

The table that follows presents information about the differences between the daily market price on secondary markets for shares of the Fund and the Fund’s NAV. NAV is the price at which the Fund issues and redeems shares. It is calculated in accordance with the standard formula for valuing mutual fund shares. The price used to calculate market returns (“Market Price”) of the Fund generally is determined using the midpoint between the highest bid and the lowest offer on the primary securities exchange on which shares of the Fund are listed for trading, as of the time that the Fund’s NAV is calculated. The Fund’s Market Price may be at, above or below its NAV. The NAV of the Fund will fluctuate with changes in the value of its portfolio holdings. The Market Price of the Fund will fluctuate in accordance with changes in its NAV, as well as market supply and demand.

Premiums or discounts are the differences (expressed as a percentage) between the NAV and Market Price of the Fund on a given day, generally at the time the NAV is calculated. A premium is the amount that the Fund is trading above the reported NAV, expressed as a percentage of the NAV. A discount is the amount that the Fund is trading below the reported NAV, expressed as a percentage of the NAV.

The following information shows the frequency of distributions of premiums and discounts for the Fund from April 1, 2010 through September 30, 2011.

Each line in the table shows the number of trading days in which the Fund traded within the premium/discount range indicated. The number of trading days in each premium/discount range is also shown as a percentage of the total number of trading days in the period covered by the table. All data presented here represents past performance, which cannot be used to predict future results.

II. Total Return Information

The table that follows presents information about the total returns of the Fund and the Underlying Index as of the fiscal year ended July 31, 2011.

“Average Annual Total Returns” represent the average annual change in value of an investment over the periods indicated. “Cumulative Total Returns” represent the total change in value of an investment over the period indicated.

The Fund’s NAV is the value of one share of the Fund as calculated in accordance with the standard formula for valuing mutual fund shares. The NAV return is based on the NAV of the Fund and the market return is based on the Market Price of the Fund. Market Price is determined by using the midpoint between the highest bid and the lowest offer on the primary stock exchange on which shares of the Fund are listed for trading, as of the time that the Fund’s NAV is calculated. Since shares of the Fund did not trade in the secondary market until after the Fund’s inception, for the period from inception to the first day of secondary market trading in shares of the Fund, the NAV of the Fund is used as a proxy for the Market Price to calculate market returns. Market and NAV returns assume that dividends and capital gain distributions have been reinvested in the Fund at Market Price and NAV, respectively.

An index is a statistical composite that tracks a specified financial market or sector. Unlike the Fund, the Underlying Index does not actually hold a portfolio of securities and therefore does not incur the expenses incurred by the Fund. These expenses negatively impact the performance of the Fund. Also, market returns do not include brokerage commissions that may be payable on secondary market transactions. If brokerage commissions were included, market returns would be lower. The returns shown in the following table do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption or sale of Fund shares. The investment return and principal value of shares of the Fund will vary with changes in market conditions. Shares of the Fund may be worth more or less than their original cost when they are redeemed or sold in the market. The Fund’s past performance is no guarantee of future results.

Fund Overview

iSHARES® MSCI KOKUSAI INDEX FUND

Ticker: TOK Stock Exchange: NYSE Arca

Investment Objective

The iShares MSCI Kokusai Index Fund (the “Fund”) seeks investment results that correspond generally to the price and yield performance, before fees and expenses, of the MSCI Kokusai Index (the “Underlying Index”).

Fees and Expenses

The following table describes the fees and expenses that you will incur if you own shares of the Fund. The investment advisory agreement between iShares Trust (the “Trust”) and BlackRock Fund Advisors (“BFA”) (the “Investment Advisory Agreement”) provides that BFA will pay all operating expenses of the Fund, except interest expenses, taxes, brokerage expenses, future distribution fees or expenses, and extraordinary expenses.

You may also incur usual and customary brokerage commissions when buying or selling shares of the Fund, which are not reflected in the example that follows:

Example. This Example is intended to help you compare the cost of owning shares of the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

Portfolio Turnover. The Fund may pay transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 4% of the average value of its portfolio.

Principal Investment Strategies

The Underlying Index is designed to measure equity market performance in those countries that MSCI Inc. (“MSCI”) has classified as having developed economies, excluding Japan (“DEEJ”). As of September 30, 2011, the MSCI Kokusai Index consisted of securities of issuers in the following countries or regions: Australia, Austria, Belgium, Canada, Denmark, Finland, France, Germany, Greece, Hong Kong, Ireland, Israel, Italy, the Netherlands, New Zealand, Norway, Portugal, Singapore, Spain, Sweden, Switzerland, the United Kingdom and the United States. Component companies include consumer staples, energy, financial and information technology companies.

BFA uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to “beat” the index it tracks and does not seek temporary defensive positions when markets decline or appear overvalued.

Indexing may eliminate the chance that the Fund will substantially outperform the Underlying Index but also may reduce some of the risks of active management, such as poor security selection. Indexing seeks to achieve lower costs and better after-tax performance by keeping portfolio turnover low in comparison to actively managed investment companies.

BFA uses a representative sampling indexing strategy to manage the Fund. “Representative sampling” is an indexing strategy that involves investing in a representative sample of securities that collectively has an investment profile similar to the Underlying Index. The securities selected are expected to have, in the aggregate, investment characteristics (based on factors such as market capitalization and industry weightings), fundamental characteristics (such as return variability and yield) and liquidity measures similar to those of the Underlying Index. The Fund may or may not hold all of the securities in the Underlying Index.

The Fund generally invests at least 80% of its assets in securities of the Underlying Index or in depositary receipts representing securities of the Underlying Index. The Fund may invest 20% of its assets in securities not included in the Underlying Index, but which BFA believes will help the Fund track the Underlying Index. For example, the Fund may invest in securities not included in its Underlying Index in order to reflect various corporate actions (such as mergers) and other changes in its Underlying Index (such as reconstitutions, additions and deletions). The Fund also may invest its other assets in futures contracts, options on futures contracts, options and swaps related to its Underlying Index as well as cash and

S-2   


Table Of Contents



cash equivalents, including shares of money market funds advised by BFA or its affiliates.

The Fund may lend securities representing up to one-third of the value of the Fund’s total assets (including the value of the collateral received).

The Underlying Index is sponsored by an organization (the “Index Provider”) that is independent of the Fund and BFA. The Index Provider determines the composition and relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index. The Fund’s Index Provider is MSCI Inc. (“MSCI”).

Industry Concentration Policy. The Fund will concentrate its investments (i.e., hold 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. For purposes of this limitation, securities of the U.S. government (including its agencies and instrumentalities) and repurchase agreements collateralized by U.S. government securities are not considered to be issued by members of any industry.

Summary of Principal Risks

As with any investment, you could lose all or part of your investment in the Fund, and the Fund’s performance could trail that of other investments. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund’s net asset value per share (“NAV”), trading price, yield, total return and ability to meet its investment objective.

Asset Class Risk. Securities in the Underlying Index or in the Fund’s portfolio may underperform in comparison to the general securities markets or other asset classes.

Concentration Risk. To the extent that the Fund’s investments are concentrated in a particular issuer, region, country, market, industry or asset class, the Fund may be susceptible to loss due to adverse occurrences affecting that issuer, region, country, market, industry or asset class.

Consumer Staples Sector Risk. The consumer staples sector may be affected by marketing campaigns, changes in consumer demands, government regulations and changes in commodity prices.

Currency Risk. Because the Fund’s NAV is determined in U.S. dollars, the Fund’s NAV could decline if the currency of a non-U.S. market in which the Fund invests depreciates against the U.S. dollar.

Energy Sector Risk. The value of securities issued by companies in the energy sector may decline for many reasons, including, without limitation, changes in commodity prices, government regulations, energy conservation efforts and potential civil liabilities.

Equity Securities Risk. Equity securities are subject to changes in value and their values may be more volatile than other asset classes.

Financial Sector Risk. Performance of companies in the financial sector may be adversely impacted by many factors, including, among others, government regulations, economic conditions, credit rating downgrades, changes in interest

S-3   


Table Of Contents



rates, and decreased liquidity in credit markets. This sector has experienced significant losses in the recent past, and the impact of more stringent capital requirements and of recent or future regulation on any individual financial company or on the sector as a whole cannot be predicted.

Geographic Risk. A natural or other disaster could occur in a geographic region in which the Fund invests, which could affect the economy or particular business operations of companies in the specific geographic region, causing an adverse impact on the Fund’s investments in the affected region.

Information Technology Sector Risk. Information technology companies face intense competition and potentially rapid product obsolescence. They are also heavily dependent on intellectual property rights and may be adversely affected by loss or impairment of those rights.

Issuer Risk. Fund performance depends on the performance of individual securities to which the Fund has exposure. Changes to the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA’s investment management strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares, losses from trading in secondary markets, periods of high volatility and disruption in the creation/redemption process of the Fund. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV.

Mid-Capitalization Companies Risk. The Fund may invest in the securities of mid-capitalization companies. Compared to large-capitalization companies, mid-capitalization companies may be less stable and more susceptible to adverse developments and their securities may be more volatile and less liquid.

Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers are subject to the risks associated with investing in those non-U.S. markets, such as heightened risks of inflation or nationalization. The Fund may lose money due to political, economic and geographic events affecting a non-U.S. issuer or market. The Fund is specifically exposed to European Economic Risk.

Passive Investment Risk. The Fund is not actively managed and BFA does not attempt to take defensive positions under any market conditions, including declining markets.

Reliance on Trading Partners Risk. The Fund invests in countries whose economies are heavily dependent upon trading with key partners. Any reduction in this trading may have an adverse impact on the Fund’s investments. Through its trading partners, the Fund is particularly exposed to U.S. Trading Partner Risk.

Securities Lending Risk. The Fund may engage in securities lending. Securities lending involves the risk that the Fund

S-4   


Table Of Contents



may lose money because the borrower of the Fund’s loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Security Risk. Some countries and regions in which the Fund invests have experienced security concerns. Incidents involving a country’s or region’s security may cause uncertainty in these markets and may adversely affect their economies and the Fund’s investments.

Tracking Error Risk. The performance of the Fund may diverge from that of the Underlying Index. Because the Fund employs a representative sampling strategy, the Fund may experience tracking error to a greater extent than a fund that seeks to replicate an index.

Valuation Risk. The value of the securities in the Fund’s portfolio may change on days when shareholders will not be able to purchase or sell the Fund’s shares.

Performance Information

The bar chart and table that follow show how the Fund has performed on a calendar year basis and provide an indication of the risks of investing in the Fund. Both assume that all dividends and distributions have been reinvested in the Fund. Past performance (before and after taxes) does not necessarily indicate how the Fund will perform in the future. Supplemental information about the Fund’s performance is shown under the heading Total Return Information in the Supplemental Information section of the Fund’s prospectus (the “Prospectus”).

Year by Year Returns1 (Years Ended December 31)


1 The Fund’s total return for the nine months ended September 30, 2011 was -12.14%.

The best calendar quarter return during the periods shown above was 20.44% in the 2nd quarter of 2009; the worst was
-22.87% in the 4th quarter of 2008.

1 After-tax returns in the table above are calculated using the historical highest individual U.S. federal marginal income tax rates and do not reflect the impact of state or local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown, and after-tax returns shown are not relevant to tax-exempt investors or investors who hold shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts (“IRAs”). Fund returns after taxes on distributions and sale of Fund shares are calculated assuming that an investor has sufficient capital gains of the same character from other investments to offset any capital losses from the sale of Fund shares. As a result, Fund returns after taxes on distributions and sale of Fund shares may exceed Fund returns before taxes and/or returns after taxes on distributions.

Management

Investment Adviser. BlackRock Fund Advisors.

Portfolio Managers. Rene Casis, Diane Hsiung and Greg Savage (the “Portfolio Managers”) are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager supervises a portfolio management team. Mr. Casis, Ms. Hsiung and Mr. Savage have been Portfolio Managers of the Fund since 2010, 2008 and 2008, respectively.

Purchase and Sale of Fund Shares

The Fund is an exchange-traded fund (commonly referred to as an “ETF”). Individual Fund shares may only be purchased and sold on a national securities exchange through a broker-dealer. The price of Fund shares is based on market price, and because ETF shares trade at market prices rather than NAV, shares may trade at a price greater than NAV (a premium) or less than NAV (a discount). The Fund will only issue or redeem shares that have been aggregated into blocks of 200,000 shares or multiples thereof (“Creation Units”) to authorized participants who have entered into agreements with the Fund’s distributor. The Fund generally will issue or redeem Creation Units in return for a designated portfolio of securities (and an amount of cash) that the Fund specifies each day.

Tax Information

The Fund intends to make distributions that may be taxable to you as ordinary income or capital gains, unless you are investing through a tax-deferred arrangement such as a 401(k) plan or an IRA.

Payments to Broker-Dealers and other Financial Intermediaries

If you purchase shares of the Fund through a broker-dealer or other financial intermediary (such as a bank), BFA or other related companies may pay the intermediary for marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems or other services related to the sale or promotion of the Fund. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.

More Information About the Fund

This Prospectus contains important information about investing in the Fund. Please read this Prospectus carefully before you make any investment decisions. Additional information regarding the Fund is available at www.iShares.com.

BFA is the investment adviser to the Fund. Shares of the Fund are listed for trading on NYSE Arca, Inc. (“NYSE Arca”). The market price for a share of the Fund may be different from the Fund’s most recent NAV.

ETFs are funds that trade like other publicly-traded securities. The Fund is designed to track an index. Similar to shares of an index mutual fund, each share of the Fund represents a partial ownership in an underlying portfolio of securities intended to track a market index. Unlike shares of a mutual fund, which can be bought and redeemed from the issuing fund by all shareholders at a price based on NAV, shares of the Fund may be purchased or redeemed directly from the Fund at NAV solely by authorized participants. Also unlike shares of a mutual fund, shares of the Fund are listed on a national securities exchange and trade in the secondary market at market prices that change throughout the day.

The Fund invests in a particular segment of the securities markets and seeks to track the performance of a securities index that generally is not representative of the market as a whole. The Fund is designed to be used as part of broader asset allocation strategies. Accordingly, an investment in the Fund should not constitute a complete investment program.

An index is a theoretical financial calculation while the Fund is an actual investment portfolio. The performance of the Fund and the Underlying Index may vary due to transaction costs, non-U.S. currency valuations, asset valuations, corporate actions (such as mergers and spin-offs), timing variances and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions (such as diversification requirements) that apply to the Fund but not to the Underlying Index or to the use of representative sampling. “Tracking error” is the difference between the performance (return) of the Fund’s portfolio and that of the Underlying Index. BFA expects that, over time, the Fund’s tracking error will not exceed 5%. Because the Fund uses a representative sampling indexing strategy, it can be expected to have a larger tracking error than if it used a replication indexing strategy. “Replication” is an indexing strategy in which a fund invests in substantially all of the securities in its underlying index in approximately the same proportions as in the underlying index.

An investment in the Fund is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, BFA or any of its affiliates.

The Fund’s investment objective and the Underlying Index may be changed without shareholder approval.

A Further Discussion of Principal Risks

The Fund is subject to various risks, including the principal risks noted below, any of which may adversely affect the Fund’s NAV, trading price, yield, total return and ability to meet its investment objective. You could lose all or part of your investment in the Fund, and the Fund could underperform other investments.

Asset Class Risk. The securities in the Underlying Index or in the Fund’s portfolio may underperform the returns of other securities or indexes that track other countries, groups of countries, regions, industries, groups of industries, markets, asset classes or sectors. Various types of securities or indexes tend to experience cycles of outperformance and underperformance in comparison to the general securities markets.

Concentration Risk. To the extent that the Fund’s portfolio reflects the Underlying Index’s concentration in the securities of a particular issuer or issuers in a particular country, group of countries, region, market, industry, group of industries, sector or asset class, the Fund may be adversely affected by the performance of those securities, may be subject to increased price volatility and may be more susceptible to adverse economic, market, political or regulatory occurrences affecting that issuer, country, group of countries, region, market, industry, group of industries, sector or asset class.

Consumer Staples Sector Risk. The Fund invests in companies in the consumer staples sector. The consumer staples sector may be affected by the permissibility of using various food additives and production methods, marketing campaigns and other factors affecting consumer demand. Tobacco companies, in particular, may be adversely affected by new laws, regulations and litigation. The consumer staples sector may also be adversely affected by changes or trends in commodity prices, which may be influenced or characterized by unpredictable factors.

Currency Risk. Because the Fund’s NAV is determined on the basis of the U.S. dollar, investors may lose money if the currency of a non-U.S. market in which the Fund invests depreciates against the U.S. dollar, even if the local currency value of the Fund’s holdings in that market increases.

Energy Sector Risk. The energy sector is cyclical and highly dependent on commodities prices. The market values of companies in the energy sector are strongly affected by the levels and volatility of global energy prices, energy supply and demand, capital expenditures on exploration and production, energy conservation efforts, exchange rates and technological advances, among other factors. Companies in this sector may be subject to substantial government regulation and contractual fixed pricing, which may increase the cost of business and limit these companies’ earnings. A significant portion of their revenues depends on a relatively small number of customers, including governmental entities and utilities. As a result, governmental budget constraints may have a material adverse effect on the stock prices of companies in this industry. Energy companies may also operate in countries with less developed regulatory regimes or a history of expropriation, nationalization or other adverse policies. Energy companies also face a significant risk of civil liability from accidents resulting in injury or loss of life or property, pollution or other environmental

mishaps, equipment malfunctions or mishandling of materials and a risk of loss from terrorism and natural disasters. Any such event could have serious consequences for the general population of the area affected and result in a material adverse impact on the Fund’s portfolio and the performance of the Fund. Energy companies can be significantly affected by the supply of, and demand for, specific products (e.g., oil and natural gas) and services, exploration and production spending, government regulation, world events and general economic conditions.

Equity Securities Risk. The Fund invests in equity securities, which are subject to changes in value that may be attributable to market perception of a particular issuer or to general stock market fluctuations that affect all issuers. Investments in equity securities may be more volatile than investments in other asset classes.

European Economic Risk. The Economic and Monetary Union of the European Union (the “EU”) requires member countries to comply with restrictions on inflation rates, deficits, interest rates, debt levels and fiscal and monetary controls, each of which may significantly affect every country in Europe. Decreasing imports or exports, changes in governmental or EU regulations on trade, changes in the exchange rate of the euro, the default or threat of default by an EU member country on its sovereign debt, and/or an economic recession in an EU member country may have a significant adverse effect on the economies of EU member countries and some or all of the DEEJ economies. The European financial markets have recently experienced volatility and have been adversely affected by concerns about economic downturns, credit rating downgrades, rising government debt levels and possible default on or restructuring of government debt in several European countries, including Greece, Ireland, Italy, Portugal and Spain. A default or debt restructuring by any European country would adversely impact holders of that country’s debt, and sellers of credit default swaps linked to that country’s creditworthiness, which may be located in countries other than those listed in the previous sentence. These events have adversely affected the value and exchange rate of the euro and may continue to significantly affect the economies of every country in Europe, including EU member countries that do not use the euro and non-EU member countries.

Financial Sector Risk. Companies in the financial sector of an economy are often subject to governmental regulation and, recently, government intervention and the potential for additional regulation, which may adversely affect the scope of their activities, the prices they can charge and the amount of capital they must maintain. Governmental regulation may change frequently and may have significant adverse consequences for companies in the financial sector, including effects not intended by such regulation. The impact of recent or future regulation in various countries on any individual financial company or on the sector as a whole cannot be predicted. Certain risks may impact the value of investments in the financial sector more severely than investments outside this sector, including the risks associated with companies that operate with substantial financial leverage. Companies in the financial sector may also be adversely affected by increases in interest rates and loan losses, decreases in the availability of money or asset valuations, credit rating downgrades and adverse conditions in other related markets. Over the past few years, the deterioration of the credit markets has impacted a broad range of mortgage, asset-backed, auction rate,

sovereign debt and other markets, including U.S. and non-U.S. credit and interbank money markets, thereby affecting a wide range of financial institutions and markets. This situation has created instability in the financial markets and caused certain financial companies to incur large losses. Some financial companies have experienced declines in the valuations of their assets, taken actions to raise capital (such as the issuance of debt or equity securities), or even ceased operations. Some financial companies have borrowed significant amounts of capital from governments and may face future government-imposed restrictions on their businesses or increased government intervention. These actions have caused the securities of many financial companies to decline in value. Insurance companies, in particular, may be subject to severe price competition, which may have an adverse impact on their profitability.

Geographic Risk. Some markets in which the Fund invests are located in parts of the world that have historically been prone to natural disasters, such as earthquakes, volcanoes, droughts, floods, hurricanes and tsunamis, and are economically sensitive to environmental events. Any natural or other disaster could have a significant adverse impact on the economies of these geographic areas, causing an adverse impact on the Fund’s investments in the affected region.

Information Technology Sector Risk. Information technology companies face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Like other technology companies, information technology companies may have limited product lines, markets, financial resources or personnel. The products of information technology companies may face obsolescence due to rapid technological developments and frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Companies in the information technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies.

Issuer Risk. The performance of the Fund depends on the performance of individual securities to which the Fund has exposure. Any issuer of these securities may perform poorly, causing the value of its securities to decline. Poor performance may be caused by poor management decisions, competitive pressures, changes in technology, expiration of patent protection, disruptions in supply, labor problems or shortages, corporate restructurings, fraudulent disclosures or other factors. Issuers may, in times of distress or at their own discretion, decide to reduce or eliminate dividends, which may also cause their stock prices to decline.

Management Risk. The Fund may not fully replicate the Underlying Index and may hold securities not included in the Underlying Index. As a result, the Fund is subject to the risk that BFA’s investment management strategy, the implementation of which is subject to a number of constraints, may not produce the intended results.

Market Risk. The Fund could lose money due to short-term market movements and over longer periods during market downturns. Securities may decline in value due to factors affecting securities markets generally or particular industries represented in the markets. The value of a security may decline due to general market conditions, economic trends or events that are not specifically related to the issuer of the security

or to factors that affect a particular industry or industries. During a general downturn in the securities markets, multiple asset classes may be negatively affected.

Market Trading Risk

Absence of Active Market. Although shares of the Fund are listed for trading on one or more stock exchanges, there can be no assurance that an active trading market for such shares will develop or be maintained.

Risk of Secondary Listings. The Fund’s shares may be listed or traded on U.S. and non-U.S. stock exchanges other than the U.S. stock exchange where the Fund’s primary listing is maintained. There can be no assurance that the Fund’s shares will continue to trade on any such stock exchange or in any market or that the Fund’s shares will continue to meet the requirements for listing or trading on any exchange or in any market. The Fund’s shares may be less actively traded in certain markets than others, and investors are subject to the execution and settlement risks and market standards of the market where they or their broker direct their trades for execution. Certain information available to investors who trade Fund shares on a U.S. stock exchange during regular U.S. market hours may not be available to investors who trade in other markets, which may result in secondary market prices in such markets being less efficient.

Secondary Market Trading Risk. Shares of the Fund may trade in the secondary market at times when the Fund does not accept orders to purchase or redeem shares. At such times, shares may trade in the secondary market with more significant premiums or discounts than might be experienced at times when the Fund accepts purchase and redemption orders.

Secondary market trading in Fund shares may be halted by a stock exchange because of market conditions or other reasons. In addition, trading in Fund shares on a stock exchange or in any market may be subject to trading halts caused by extraordinary market volatility pursuant to “circuit breaker” rules on the stock exchange or market. There can be no assurance that the requirements necessary to maintain the listing or trading of Fund shares will continue to be met or will remain unchanged.

Shares of the Fund May Trade at Prices Other Than NAV. Shares of the Fund trade on stock exchanges at prices at, above or below their most recent NAV. The NAV of the Fund is calculated at the end of each business day and fluctuates with changes in the market value of the Fund’s holdings since the most recent calculation. The trading prices of the Fund’s shares fluctuate continuously throughout trading hours based on market supply and demand rather than NAV. The trading prices of the Fund’s shares may deviate significantly from NAV during periods of market volatility. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV. However, because shares can be created and redeemed in Creation Units at NAV (unlike shares of many closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their NAVs), BFA believes that large discounts or premiums to the NAV of the Fund are not likely to be sustained over the long-term. While the creation/redemption feature is designed to make it likely that the Fund’s shares normally will trade on stock exchanges at prices close to the Fund’s next calculated NAV, exchange prices are not

expected to correlate exactly with the Fund’s NAV due to timing reasons as well as market supply and demand factors. In addition, disruptions to creations and redemptions or extreme market volatility may result in trading prices for shares of the Fund that differ significantly from its NAV.

Costs of Buying or Selling Fund Shares. Buying or selling Fund shares on an exchange involves two types of costs that apply to all securities transactions. When buying or selling shares of the Fund through a broker, you will likely incur a brokerage commission or other charges imposed by brokers as determined by that broker. In addition, you may incur the cost of the “spread” – that is, the difference between what investors are willing to pay for Fund shares (the “bid” price) and the price at which they are willing to sell Fund shares (the “ask” price). Because of the costs inherent in buying or selling Fund shares, frequent trading may detract significantly from investment results and an investment in Fund shares may not be advisable for investors who anticipate regularly making small investments.

Mid-Capitalization Companies Risk. Many of the companies in which the Fund invests are considered mid-capitalization companies. Stock prices of mid-capitalization companies may be more volatile than those of large-capitalization companies and, therefore, the Fund’s share price may be more volatile than those of funds that invest a larger percentage of their assets in stocks issued by large-capitalization companies. Stock prices of mid-capitalization companies are also more vulnerable than those of large-capitalization companies to adverse business or economic developments, and the stocks of mid-capitalization companies may be less liquid, making it difficult for the Fund to buy and sell them. In addition, mid-capitalization companies generally have less diverse product lines than large-capitalization companies and are more susceptible to adverse developments related to their products.

Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers are subject to all of the risks of investing in the markets where such issuers are located, including heightened risks of inflation or nationalization and market fluctuations caused by economic and political developments. As a result of investing in non-U.S. securities, the Fund may be subject to increased risk of loss caused by any of the factors listed below:

  • Lower levels of liquidity and market efficiency;
  • Greater securities price volatility;
  • Exchange rate fluctuations and exchange controls;
  • Less availability of public information about issuers;
  • Limitations on foreign ownership of securities;
  • Imposition of withholding or other taxes;
  • Imposition of restrictions on the expatriation of the funds or other assets of the Fund;
  • Higher transaction and custody costs and delays in settlement procedures;
  • Difficulties in enforcing contractual obligations;
  • Lower levels of regulation of the securities market;
  • Weaker accounting, disclosure and reporting requirements; and
  • Legal principles related to corporate governance, directors’ fiduciary duties and liabilities and stockholders’ rights in markets in which the Fund invests may differ and/or may not be as extensive or protective as those that apply in the United States.

Passive Investment Risk. The Fund is not actively managed and may be affected by a general decline in market segments related to the Underlying Index. The Fund invests in securities included in, or representative of, the Underlying Index regardless of their investment merits. BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

Reliance on Trading Partners Risk. The economies of DEEJ nations are dependent on each other and on Japan as key trading partners. Reduction in spending on the products and services of the DEEJ regions or changes in any of these economies may cause an adverse impact on the companies in which the Fund invests.


U.S. Trading Partners Risk. The United States is a significant, and in some cases the most significant, trading partner of or foreign investor in certain DEEJ nations and the economies of these countries may be particularly affected by changes in the U.S. economy. Decreasing U.S. imports, new trade regulations, changes in the U.S. dollar exchange rate or a recession in the United States may have a material adverse effect on economies of DEEJ nations.

Securities Lending Risk. The Fund may engage in securities lending. Securities lending involves the risk that the Fund may lose money because the borrower of the Fund’s loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for the loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Security Risk. Some geographic areas in which the Fund invests have experienced acts of terrorism or strained international relations due to territorial disputes, historical animosities or other defense concerns. These situations may cause uncertainty in the markets of these geographic areas and may adversely affect the performance of their economies.

Tracking Error Risk. Imperfect correlation between the Fund’s portfolio securities and those in the Underlying Index, rounding of prices, changes to the Underlying Index and regulatory requirements may cause tracking error, which is the divergence of the Fund’s performance from that of the Underlying Index. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Underlying Index does not. Because the Fund employs a representative sampling strategy, the Fund may experience tracking error to a greater extent than a fund that seeks to replicate an index.

Valuation Risk. Because non-U.S. exchanges may be open on days when the Fund does not price its shares, the value of the securities in the Fund’s portfolio may change on days when shareholders will not be able to purchase or sell the Fund’s shares. In

addition, for purposes of calculating the Fund’s NAV, the value of assets denominated in non-U.S. currencies is converted into U.S. dollars using exchange rates deemed appropriate by BFA. This conversion may result in a difference between the prices used to calculate the Fund’s NAV and the prices used by the Underlying Index, which, in turn, could result in a difference between the Fund’s performance and the performance of the Underlying Index.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

Consumer Discretionary Sector Risk. The success of consumer product manufacturers and retailers is tied closely to the performance of domestic and international economies, interest rates, exchange rates, competition, consumer confidence, changes in demographics and consumer preferences. Companies in the consumer discretionary sector depend heavily on disposable household income and consumer spending, and may be strongly affected by social trends and marketing campaigns. These companies may be subject to severe competition, which may have an adverse impact on their profitability.

Health Care Sector Risk. The profitability of companies in the health care sector may be affected by extensive government regulations, restrictions on government reimbursement for medical expenses, rising costs of medical products and services, pricing pressure, an increased emphasis on outpatient services, limited number of products, industry innovation, changes in technologies and other market developments. Many health care companies are heavily dependent on patent protection. The expiration of patents may adversely affect the profitability of these companies. Many health care companies are subject to extensive litigation based on product liability and similar claims. Health care companies are subject to competitive forces that may make it difficult to raise prices and, in fact, may result in price discounting. Many new products in the health care sector may be subject to regulatory approvals. The process of obtaining such approvals may be long and costly. Companies in the health care sector may be thinly capitalized and may be susceptible to product obsolescence.

Industrials Sector Risk. The stock prices of companies in the industrials sector are affected by supply and demand, both for their specific product or service and for industrials sector products in general. The products of manufacturing companies may face obsolescence due to rapid technological developments and frequent new product introduction. Government regulations, world events, economic conditions and exchange rates affect the performance of companies in the industrials sector. Companies in the industrials sector may be adversely affected by liability for environmental damage, product liability claims and exchange rates. The industrials sector may also be adversely affected by changes or trends in commodity prices, which may be influenced by unpredictable factors.

Materials Sector Risk. Companies in the materials sector could be adversely affected by commodity price volatility, exchange rates, import controls, increased competition, depletion of resources, technical progress, labor relations, exchange rates and

government regulations, among other factors. Also, companies in the materials sector are at risk of liability for environmental damage and product liability claims. Production of materials may exceed demand as a result of market imbalances or economic downturns, leading to poor investment returns.

Portfolio Holdings Information

A description of the Trust’s policies and procedures with respect to the disclosure of the Fund’s portfolio securities is available in the Fund’s Statement of Additional Information (“SAI”). The top holdings of the Fund can be found at www.iShares.com. Fund fact sheets provide information regarding the Fund’s top holdings and may be requested by calling 1-800-iShares (1-800-474-2737).

Management

Investment Adviser. As investment adviser, BFA has overall responsibility for the general management and administration of the Trust. BFA provides an investment program for the Fund and manages the investment of the Fund’s assets. In managing the Fund, BFA may draw upon the research and expertise of its asset management affiliates with respect to certain portfolio securities. In seeking to achieve the Fund’s investment objective, BFA uses teams of portfolio managers, investment strategists and other investment specialists. This team approach brings together many disciplines and leverages BFA’s extensive resources.

Pursuant to the Investment Advisory Agreement between BFA and the Trust (entered into on behalf of the Fund), BFA is responsible for substantially all expenses of the Fund, except interest expenses, taxes, brokerage expenses, future distribution fees or expenses and extraordinary expenses.

For its investment advisory services to the Fund, BFA is entitled to receive a management fee from the Fund based on a percentage of the Fund’s average daily net assets, at the annual rate of 0.25%.

BFA is located at 400 Howard Street, San Francisco, CA 94105. It is a wholly owned subsidiary of BTC, which in turn is indirectly wholly-owned by BlackRock, Inc. (“BlackRock”). As of September 30, 2011, BTC and its affiliates, including BFA and BlackRock, provided investment advisory services for assets in excess of $3.35 trillion. BFA, BTC, BlackRock Execution Services, BlackRock and their affiliates deal, trade and invest for their own accounts in the types of securities in which the Fund may also invest.

A discussion regarding the basis for the Trust’s Board of Trustees’ (the “Board”) approval of the Investment Advisory Agreement with BFA is available in the Fund’s annual report for the period ended July 31.

Portfolio Managers. Rene Casis, Diane Hsiung and Greg Savage are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager is responsible for various functions related to portfolio management, including, but not limited to, investing cash inflows, coordinating with members of his or her portfolio management team to focus on certain asset classes, implementing investment

strategy, researching and reviewing investment strategy and overseeing members of his or her portfolio management team that have more limited responsibilities.

Rene Casis has been employed by BFA (formerly, Barclays Global Fund Advisors (“BGFA”)) and BTC (formerly, Barclays Global Investors, N.A. (“BGI”)) as a senior portfolio manager since 2009. From 2005 to 2009, Mr. Casis was a trader at Barclays Capital. Prior to that, Mr. Casis was a portfolio manager from 2000 to 2005 for BGFA and BGI. Mr. Casis has been a Portfolio Manager of the Fund since 2010.

Diane Hsiung has been employed by BFA and BTC as a senior portfolio manager since 2007. Prior to that, Ms. Hsiung was a portfolio manager from 2002 to 2006 for BGFA and BGI. Ms. Hsiung has been a Portfolio Manager of the Fund since 2008.

Greg Savage has been employed by BFA and BTC as a senior portfolio manager since 2006. Prior to that, Mr. Savage was a portfolio manager from 2001 to 2006 for BGFA and BGI. Mr. Savage has been a Portfolio Manager of the Fund since 2008.

The Fund’s SAI provides additional information about the Portfolio Managers’ compensation, other accounts managed by the Portfolio Managers and the Portfolio Managers’ ownership (if any) of shares in the Fund.

Administrator, Custodian and Transfer Agent. State Street Bank and Trust Company (“State Street”) is the administrator, custodian and transfer agent for the Fund.

Conflicts of Interest. BFA wants you to know that there are certain entities with which BFA has relationships that may give rise to conflicts of interest, or the appearance of conflicts of interest. These entities include the following: BFA’s affiliates (including BlackRock and The PNC Financial Services Group, Inc., and each of their affiliates, directors, partners, trustees, managing members, officers and employees (collectively, the “Affiliates”)) and BlackRock’s significant shareholder, Barclays Bank PLC and its affiliates, including Barclays PLC (each, an “Entity” and together, the “Entities”).

The activities of BFA, the Affiliates and the Entities in the management of, or their interest in, their own accounts and other accounts they manage, may present conflicts of interest that could disadvantage the Fund and its shareholders. BFA and its Affiliates or the Entities provide investment management services to other funds and discretionary managed accounts that may follow an investment program similar to that of the Fund. BFA, its Affiliates and the Entities are involved worldwide with a broad spectrum of financial services and asset management activities and may engage in the ordinary course of business in activities in which their interests or the interests of their clients may conflict with those of the Fund. BFA, one or more of the Affiliates or the Entities acts, or may act, as an investor, investment banker, research provider, investment manager, financier, underwriter, advisor, market maker, trader, prime broker, lender, agent or principal, and have other direct and indirect interests, in securities, currencies and other instruments in which the Fund may directly or indirectly invest. Thus, it is likely that the Fund will have multiple business relationships with and will invest in, engage in transactions with, make voting decisions with respect to, or obtain services from, entities for which BFA, an Affiliate or an Entity performs or seeks to perform investment banking or other services.

BFA or one or more Affiliates or Entities may engage in proprietary trading and advise accounts and funds that have investment objectives similar to those of the Fund and/or that engage in and compete for transactions in the same types of securities, currencies and other instruments as the Fund, including in securities issued by other open-end and closed-end investment management companies, including investment companies that are affiliated with the Fund and BFA, to the extent permitted under the Investment Company Act of 1940, as amended (the “1940 Act”). The trading activities of BFA, these Affiliates and Entities are carried out without reference to positions held directly or indirectly by the Fund and may result in BFA, an Affiliate or an Entity having positions that are adverse to those of the Fund.

No Affiliate or Entity is under any obligation to share any investment opportunity, idea or strategy with the Fund. As a result, an Affiliate or an Entity may compete with the Fund for appropriate investment opportunities. As a result of this and several other factors, the results of the Fund’s investment activities may differ from those of an Affiliate or an Entity and of other accounts managed by an Affiliate or an Entity, and it is possible that the Fund could sustain losses during periods in which one or more Affiliates or Entities and other accounts achieve profits on their trading for proprietary or other accounts. The opposite result is also possible.

The Fund may, from time to time, enter into transactions in which BFA or an Affiliate’s or an Entity’s clients have an interest adverse to the Fund. Furthermore, transactions undertaken by Affiliate-advised clients may adversely impact the Fund. Transactions by one or more Affiliate- or Entity-advised clients or BFA may have the effect of diluting or otherwise disadvantaging the values, prices or investment strategies of the Fund.

An Entity may maintain securities indices as part of its product offerings. Index-based funds seek to track the performance of securities indices and may use the name of the index in the fund name. Index providers, including the Entities, may be paid licensing fees for use of their indices or index names. Entities will not be obligated to license their indices to BFA and its Affiliates, and BFA and its Affiliates will not be assured that the terms of any index licensing agreement with the Entities will be as favorable as those terms offered to other index licensees.

The Fund’s activities may be limited because of regulatory restrictions applicable to one or more Affiliates or Entities, and/or their internal policies designed to comply with such restrictions. In addition, the Fund may invest in securities of companies with which an Affiliate or an Entity has or is trying to develop investment banking relationships or in which an Affiliate or an Entity has significant debt or equity investments. The Fund also may invest in securities of companies for which an Affiliate or an Entity provides or may some day provide research coverage. An Affiliate or an Entity may have business relationships with and purchase or distribute or sell services or products from or to distributors, consultants or others who recommend the Fund or who engage in transactions with or for the Fund, and may receive compensation for such services. The Fund may also make brokerage and other payments to Affiliates or Entities in connection with the Fund’s portfolio investment transactions.

Pursuant to a securities lending program approved by the Board, the Fund has retained an Affiliate of BFA to serve as the securities lending agent for the Fund to the extent that the Fund participates in the securities lending program. For these services, the

lending agent may receive a fee from the Fund, including a fee based on the returns earned on the Fund’s investment of the cash received as collateral for any loaned securities. In addition, one or more Affiliates may be among the entities to which the Fund may lend its portfolio securities under the securities lending program.

The activities of BFA, the Affiliates or Entities may give rise to other conflicts of interest that could disadvantage the Fund and its shareholders. BFA has adopted policies and procedures designed to address these potential conflicts of interest. See the Fund’s SAI for further information.

Shareholder Information

Additional shareholder information, including how to buy and sell shares of the Fund, is available free of charge by calling toll-free: 1-800-iShares (1-800-474-2737) or visiting our website at www.iShares.com.

Buying and Selling Shares. Shares of the Fund may be acquired or redeemed directly from the Fund only in Creation Units or multiples thereof, as discussed in the Creations and Redemptions section of this Prospectus. Only an Authorized Participant (as defined in the Creations and Redemptions section) may engage in creation or redemption transactions directly with the Fund. Once created, shares of the Fund generally trade in the secondary market in amounts less than a Creation Unit.

Shares of the Fund are listed on a national securities exchange for trading during the trading day. Shares can be bought and sold throughout the trading day like shares of other publicly-traded companies. The Trust does not impose any minimum investment for shares of the Fund purchased on an exchange. The Fund’s shares trade under the trading symbol “TOK.”

Buying or selling Fund shares on an exchange involves two types of costs that may apply to all securities transactions. When buying or selling shares of the Fund through a broker, you will likely incur a brokerage commission or other charges determined by your broker. The commission is frequently a fixed amount and may be a significant proportional cost for investors seeking to buy or sell small amounts of shares. In addition, you may incur the cost of the “spread” – that is, any difference between the bid price and the ask price. The spread varies over time for shares of the Fund based on its trading volume and market liquidity, and is generally lower if the Fund has a lot of trading volume and market liquidity, and higher if the Fund has little trading volume and market liquidity.

The Board has adopted a policy of not monitoring for frequent purchases and redemptions of Fund shares (“frequent trading”) that appear to attempt to take advantage of a potential arbitrage opportunity presented by a lag between a change in the value of the Fund’s portfolio securities after the close of the primary markets for the Fund’s portfolio securities and the reflection of that change in the Fund’s NAV (“market timing”), because the Fund generally sells and redeems its shares directly through transactions that are in-kind and/or for cash, subject to the conditions described below under Creations and Redemptions. The Board has not adopted a policy of monitoring for other frequent trading activity because shares of the Fund are listed for trading on a national securities exchange.

The national securities exchange on which the Fund’s shares are listed is open for trading Monday through Friday and is closed on weekends and the following holidays: New Year’s Day, Martin Luther King, Jr. Day, Presidents’ Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day. The Fund’s primary listing exchange is NYSE Arca.

Section 12(d)(1) of the 1940 Act restricts investments by investment companies in the securities of other investment companies. Registered investment companies are permitted to invest in the Fund beyond the limits set forth in Section 12(d)(1), subject to certain terms and conditions set forth in SEC rules or in an SEC exemptive order issued to the Trust. In order for a registered investment company to invest in shares of the Fund beyond the limitations of Section 12(d)(1) pursuant to the exemptive relief obtained by the Trust, the registered investment company must enter into an agreement with the Trust.

Book Entry. Shares of the Fund are held in book-entry form, which means that no stock certificates are issued. The Depository Trust Company (“DTC”) or its nominee is the record owner of all outstanding shares of the Fund and is recognized as the owner of all shares for all purposes.

Investors owning shares of the Fund are beneficial owners as shown on the records of DTC or its participants. DTC serves as the securities depository for shares of the Fund. DTC participants include securities brokers and dealers, banks, trust companies, clearing corporations and other institutions that directly or indirectly maintain a custodial relationship with DTC. As a beneficial owner of shares, you are not entitled to receive physical delivery of stock certificates or to have shares registered in your name, and you are not considered a registered owner of shares. Therefore, to exercise any right as an owner of shares, you must rely upon the procedures of DTC and its participants. These procedures are the same as those that apply to any other securities that you hold in book-entry or “street name” form.

Share Prices. The trading prices of the Fund’s shares in the secondary market generally differ from the Fund’s daily NAV and are affected by market forces such as supply and demand, economic conditions and other factors. Information regarding the intraday value of shares of the Fund, also known as the “indicative optimized portfolio value” (“IOPV”), is disseminated every 15 seconds throughout the trading day by the national securities exchange on which the Fund’s shares are listed or by market data vendors or other information providers. The IOPV is based on the current market value of the securities and/or cash required to be deposited in exchange for a Creation Unit. The IOPV does not necessarily reflect the precise composition of the current portfolio of securities held by the Fund at a particular point in time or the best possible valuation of the current portfolio. Therefore, the IOPV should not be viewed as a “real-time” update of the Fund’s NAV, which is computed only once a day. The IOPV is generally determined by using both current market quotations and/or price quotations obtained from broker-dealers that may trade in the portfolio securities held by the Fund. The quotations of certain Fund holdings may not be updated during U.S. trading hours if such holdings do not trade in the United States. The Fund is not involved in, or responsible for, the calculation or dissemination of the IOPV and makes no representation or warranty as to its accuracy.

Determination of Net Asset Value. The NAV of the Fund normally is determined once daily Monday through Friday, generally as of the regularly scheduled close of business of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m., Eastern time) on each day that the NYSE is open for trading, based on prices at the time of closing provided that (a) any Fund assets or liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers (as detailed below) and (b) U.S. fixed income assets may be valued as of the announced closing time for trading in fixed income instruments in a particular market or exchange. The NAV of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets held by the Fund, and its liabilities, are determined pursuant to valuation policies and procedures approved by the Board. The Fund’s assets and liabilities are valued primarily on the basis of market quotations.

Equity investments are valued at market value, which is generally determined using the last reported official closing price or last trading price on the exchange or market on which the security is primarily traded at the time of valuation.

The Fund invests in foreign securities. Foreign currency exchange rates are generally determined as of 4:00 p.m., London time. Foreign securities owned by the Fund may trade on weekends or other days when the Fund does not price its shares. As a result, the Fund’s NAV may change on days when Authorized Participants will not be able to purchase or redeem Fund shares.

Generally, trading in foreign securities, U.S. government securities, money market instruments and certain fixed-income securities is substantially completed each day at various times prior to the close of business on the NYSE. The values of such securities used in computing the NAV of the Fund are determined as of such times.

When market quotations are not readily available or are believed by BFA to be unreliable, the Fund’s investments are valued at fair value. Fair value determinations are made by BFA in accordance with policies and procedures approved by the Fund’s Board. BFA may conclude that a market quotation is not readily available or is unreliable if a security or other asset or liability does not have a price source due to its lack of liquidity, if a market quotation differs significantly from recent price quotations or otherwise no longer appears to reflect fair value, where the security or other asset or liability is thinly traded, or where there is a significant event subsequent to the most recent market quotation. A “significant event” is an event that, in the judgment of BFA, is likely to cause a material change to the closing market price of the asset or liability held by the Fund. Foreign securities whose values are affected by volatility that occurs in U.S. markets on a trading day after the close of foreign securities markets may be fair valued.

Fair value represents a good faith approximation of the value of an asset or liability. The fair value of an asset or liability held by the Fund is the amount the Fund might reasonably expect to receive from the current sale of that asset or the cost to extinguish that liability in an arm’s-length transaction. Valuing the Fund’s investments

using fair value pricing will result in prices that may differ from current market valuations and that may not be the price at which those investments could have been sold during the period in which the particular fair values were used. Use of fair value prices and certain current market valuations could result in a difference between the prices used to calculate the Fund’s NAV and the prices used by the Underlying Index, which, in turn, could result in a difference between the Fund’s performance and the performance of the Underlying Index.

The value of assets or liabilities denominated in non-U.S. currencies will be converted into U.S. dollars using exchange rates deemed appropriate by BFA as investment adviser. Use of a rate different from the rate used by the Index Provider may adversely affect the Fund’s ability to track the Underlying Index.

Dividends and Distributions

General Policies. Dividends from net investment income, if any, generally are declared and paid semi-annually by the Fund. Distributions of net realized securities gains, if any, generally are declared and paid once a year, but the Trust may make distributions on a more frequent basis for the Fund. The Trust reserves the right to declare special distributions if, in its reasonable discretion, such action is necessary or advisable to preserve its status as a regulated investment company (“RIC”) or to avoid imposition of income or excise taxes on undistributed income or realized gains.

Dividends and other distributions on shares of the Fund are distributed on a pro rata basis to beneficial owners of such shares. Dividend payments are made through DTC participants and indirect participants to beneficial owners then of record with proceeds received from the Fund.

Dividend Reinvestment Service. No dividend reinvestment service is provided by the Trust. Broker-dealers may make available the DTC book-entry Dividend Reinvestment Service for use by beneficial owners of the Fund for reinvestment of their dividend distributions. Beneficial owners should contact their broker to determine the availability and costs of the service and the details of participation therein. Brokers may require beneficial owners to adhere to specific procedures and timetables. If this service is available and used, dividend distributions of both income and realized gains will be automatically reinvested in additional whole shares of the Fund purchased in the secondary market.

Taxes. As with any investment, you should consider how your investment in shares of the Fund will be taxed. The tax information in this Prospectus is provided as general information, based on current law. You should consult your own tax professional about the tax consequences of an investment in shares of the Fund.

Unless your investment in Fund shares is made through a tax-exempt entity or tax-deferred retirement account, such as an IRA, you need to be aware of the possible tax consequences when the Fund makes distributions or you sell Fund shares.

Taxes on Distributions. Distributions from the Fund’s net investment income (other than qualified dividend income), including distributions of income from securities lending and distributions out of the Fund’s net short-term capital gains, if any, are taxable to you as ordinary income. Distributions by the Fund of net long-term capital gains in excess of net short-term capital losses (capital gain dividends) are taxable to

you as long-term capital gains, generally at a 15% tax rate (0% at certain income levels), regardless of how long you have held the Fund’s shares. Distributions by the Fund that qualify as qualified dividend income are taxable to you at long-term capital gain rates for taxable years beginning on or before December 31, 2012. The 15% and 0% tax rates expire for taxable years beginning after December 31, 2012. Maximum long-term capital gain income tax rates are scheduled to rise to 20% in 2013. Beginning in 2013, a 3.8% U.S. federal Medicare contribution tax will be imposed on “net investment income,” including interest, dividends, and capital gains, of U.S. individuals with income exceeding $200,000 (or $250,000 if married and filing jointly), and of estates and trusts.

Dividends will be qualified dividend income to you if they are attributable to qualified dividend income received by the Fund. Generally, qualified dividend income includes dividend income from taxable U.S. corporations and qualified non-U.S. corporations, provided that the Fund satisfies certain holding period requirements in respect of the stock of such corporations and has not hedged its position in the stock in certain ways. Substitute dividends received by the Fund with respect to dividends paid on securities lent out will not be qualified dividend income. For this purpose, a qualified non-U.S. corporation means any non-U.S. corporation that is eligible for benefits under a comprehensive income tax treaty with the United States, which includes an exchange of information program or if the stock with respect to which the dividend was paid is readily tradable on an established United States securities market. The term excludes a corporation that is a passive foreign investment company.

Dividends received by the Fund from a real estate investment trust (“REIT”) or another RIC generally are qualified dividend income only to the extent the dividend distributions are made out of qualified dividend income received by such REIT or RIC. It is expected that dividends received by the Fund from a REIT and distributed to a shareholder generally will be taxable to the shareholder as ordinary income.

For a dividend to be treated as qualified dividend income, the dividend must be received with respect to a share of stock held without being hedged by the Fund, and with respect to a share of the Fund held without being hedged by you, for 61 days during the 121-day period beginning at the date which is 60 days before the date on which such share becomes ex-dividend with respect to such dividend or, in the case of certain preferred stock, 91 days during the 181-day period beginning 90 days before such date.

If your Fund shares are loaned out pursuant to a securities lending arrangement, you may lose the ability to use foreign tax credits passed through by the Fund or to treat Fund dividends paid while the shares are held by the borrower as qualified dividend income.

In general, your distributions are subject to U.S. federal income tax for the year when they are paid. Certain distributions paid in January, however, may be treated as paid on December 31 of the prior year.

If the Fund’s distributions exceed current and accumulated earnings and profits, all or a portion of the distributions made in the taxable year may be recharacterized as a return of capital to shareholders. A return of capital distribution generally will not be

taxable but will reduce the shareholder’s cost basis and result in a higher capital gain or lower capital loss when those shares on which the distribution was received are sold. Once a shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain, if the shareholder holds shares of the Fund as capital assets.

If you are neither a resident nor a citizen of the United States or if you are a non-U.S. entity, the Fund’s ordinary income dividends (which include distributions of net short-term capital gains) will generally be subject to a 30% U.S. withholding tax, unless a lower treaty rate applies, provided that withholding tax will generally not apply to any gain or income realized by a non-U.S. shareholder in respect of any distributions of long-term capital gains or upon the sale or other disposition of shares of the Fund.

A 30% withholding tax will be imposed on dividends paid after December 31, 2013, and redemption proceeds paid after December 31, 2014, to (i) foreign financial institutions including non-U.S. investment funds unless they agree to collect and disclose to the Internal Revenue Service (“IRS”) information regarding their direct and indirect U.S. account holders and (ii) certain other foreign entities, unless they certify certain information regarding their direct and indirect U.S. owners. To avoid withholding, foreign financial institutions will need to enter into agreements with the IRS that state that they will provide the IRS information, including the name, address and taxpayer identification number of direct and indirect U.S. account holders, comply with due diligence procedures with respect to the identification of U.S. accounts, report to the IRS certain information with respect to U.S. accounts maintained, agree to withhold tax on certain payments made to non-compliant foreign financial institutions or to account holders who fail to provide the required information, and determine certain other information as to their account holders. Other foreign entities will need to provide the name, address, and taxpayer identification number of each substantial U.S. owner or certifications of no substantial U.S. ownership unless certain exceptions apply.

Dividends, interest and capital gains earned by the Fund with respect to non-U.S. securities may give rise to withholding and other taxes imposed by non-U.S. countries. Tax conventions between certain countries and the United States may reduce or eliminate such taxes. If more than 50% of the total assets of the Fund at the close of a year consists of non-U.S. stocks or securities, the Fund may “pass through” to you certain non-U.S. income taxes (including withholding taxes) paid by the Fund. This means that you would be considered to have received as an additional dividend your share of such non-U.S. taxes, but you may be entitled to either a corresponding tax deduction in calculating your taxable income, or, subject to certain limitations, a credit in calculating your U.S. federal income tax.

For purposes of foreign tax credits for U.S. shareholders of the Fund, foreign capital gains taxes may not produce associated foreign source income, thereby limiting a U.S. person’s ability to use such credits.

If you are a resident or a citizen of the United States, by law, back up withholding will apply to your distributions and proceeds if you have not provided a taxpayer identification number or social security number and made other required certifications.

Taxes When Shares are Sold. Currently, any capital gain or loss realized upon a sale of Fund shares is generally treated as a long-term gain or loss if the shares have been held for more than one year. Any capital gain or loss realized upon a sale of Fund shares held for one year or less is generally treated as short-term gain or loss, except that any capital loss on the sale of shares held for six months or less is treated as long-term capital loss to the extent that capital gain dividends were paid with respect to such shares. Beginning in 2013, any such capital gains, including from sales of Fund shares or from capital gain dividends, will be included in “net investment income” for purposes of the 3.8% U.S. federal Medicare contribution tax mentioned above.

The foregoing discussion summarizes some of the consequences under current U.S. federal tax law of an investment in the Fund. It is not a substitute for personal tax advice. You may also be subject to state and local taxation on Fund distributions and sales of shares. Consult your personal tax adviser about the potential tax consequences of an investment in shares of the Fund under all applicable tax laws.

Creations and Redemptions. Prior to trading in the secondary market, shares of the Fund are “created” at NAV by market makers, large investors and institutions only in block-size Creation Units of 200,000 shares or multiples thereof. Each “creator” or “Authorized Participant” enters into an authorized participant agreement with the Fund’s distributor, SEI Investments Distribution Co. (the “Distributor”). Only an Authorized Participant may create or redeem Creation Units directly with the Fund. A creation transaction, which is subject to acceptance by the transfer agent, generally takes place when an Authorized Participant deposits into the Fund a designated portfolio of securities and a specified amount of cash approximating the holdings of the Fund in exchange for a specified number of Creation Units. To the extent practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund.

Similarly, shares can be redeemed only in Creation Units, generally for a designated portfolio of securities and a specified amount of cash held by the Fund (“Fund Securities”). Except when aggregated in Creation Units, shares are not redeemable by the Fund. The prices at which creations and redemptions occur are based on the next calculation of NAV after an order is received in a form described in the authorized participant agreement.

The Fund intends to comply with the U.S. federal securities laws in accepting securities for deposit and satisfying redemptions with redemption securities by, among other means, assuring that any securities accepted for deposit and any securities used to satisfy redemption requests will be sold in transactions that would be exempt from registration under the Securities Act of 1933, as amended (the “1933 Act”). Further, an Authorized Participant that is not a “qualified institutional buyer,” as such term is defined under Rule 144A of the 1933 Act, will not be able to receive Fund Securities that are restricted securities eligible for resale under Rule 144A.

Creations and redemptions must be made through a firm that is either a member of the Continuous Net Settlement System of the National Securities Clearing Corporation or a DTC participant and has executed an agreement with the Distributor with respect to creations and redemptions of Creation Unit aggregations. Information about the

procedures regarding creation and redemption of Creation Units (including the cut-off times for receipt of creation and redemption orders) is included in the Fund’s SAI.

Because new shares may be created and issued on an ongoing basis, at any point during the life of the Fund a “distribution,” as such term is used in the 1933 Act, may be occurring. Broker-dealers and other persons are cautioned that some activities on their part may, depending on the circumstances, result in their being deemed participants in a distribution in a manner that could render them statutory underwriters and subject to the prospectus delivery and liability provisions of the 1933 Act. Any determination of whether one is an underwriter must take into account all the relevant facts and circumstances of each particular case.

Broker-dealers should also note that dealers who are not “underwriters” but are participating in a distribution (as contrasted to ordinary secondary transactions), and thus dealing with shares that are part of an “unsold allotment” within the meaning of Section 4(3)(C) of the 1933 Act, would be unable to take advantage of the prospectus delivery exemption provided by Section 4(3) of the 1933 Act. For delivery of prospectuses to exchange members, the prospectus delivery mechanism of Rule 153 under the 1933 Act is available only with respect to transactions on a national securities exchange.

Costs Associated with Creations and Redemptions. Authorized Participants are charged standard creation and redemption transaction fees to offset transfer and other transaction costs associated with the issuance and redemption of Creation Units. The standard creation and redemption transaction fees are set forth in the table below. The standard creation transaction fee is charged to the Authorized Participant on the day such Authorized Participant creates a Creation Unit, and is the same regardless of the number of Creation Units purchased by the Authorized Participant on the applicable business day. Similarly, the standard redemption transaction fee is charged to the Authorized Participant on the day such Authorized Participant redeems a Creation Unit, and is the same regardless of the number of Creation Units redeemed by the Authorized Participant on the applicable business day. Creations and redemptions for cash (when cash creations and redemptions (in whole or in part) are available or specified) are also subject to an additional charge (up to the maximum amounts shown in the table below). This charge is intended to compensate for brokerage, tax, foreign exchange, execution, market impact and other costs and expenses related to cash transactions. Investors who use the services of a broker or other financial intermediary may pay fees for such services.

The following table shows, as of September 30, 2011, the approximate value of one Creation Unit, standard fees and maximum additional charges for creations and redemptions (as described above):

* As a percentage of the net asset value per Creation Unit, inclusive, in the case of redemptions, of the standard redemption transaction fee.

Householding. Householding is an option available to certain Fund investors. Householding is a method of delivery, based on the preference of the individual investor, in which a single copy of certain shareholder documents can be delivered to investors who share the same address, even if their accounts are registered under different names. Please contact your broker-dealer if you are interested in enrolling in householding and receiving a single copy of prospectuses and other shareholder documents, or if you are currently enrolled in householding and wish to change your householding status.

Distribution

The Distributor distributes Creation Units for the Fund on an agency basis. The Distributor does not maintain a secondary market in shares of the Fund. The Distributor has no role in determining the policies of the Fund or the securities that are purchased or sold by the Fund. The Distributor’s principal address is One Freedom Valley Drive, Oaks, PA 19456.

In addition, BFA or its Affiliates make payments to broker-dealers, banks or other financial intermediaries (together, “intermediaries”) related to marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems, or their making shares of the Fund and certain other iShares funds available to their customers. Such payments, which may be significant to the intermediary, are not made by the Fund. Rather, such payments are made by BFA or its Affiliates from their own resources, which come directly or indirectly in part from fees paid by the iShares funds complex. Payments of this type are sometimes referred to as revenue-sharing payments. A financial intermediary may make decisions about which investment options it recommends or makes available, or the level of services provided, to its customers based on the revenue-sharing payments it is eligible to receive. Therefore, such payments to an intermediary create conflicts of interest between the intermediary and its customers and may cause the intermediary to recommend the Fund or other iShares funds over another investment. More information regarding these payments is contained in the Fund’s SAI. Please contact your salesperson or other investment professional for more information regarding any such payments his or her firm may receive from BFA or its Affiliates.

Financial Highlights

The financial highlights table is intended to help investors understand the Fund’s financial performance since inception. Certain information reflects financial results for a single share of the Fund. The total returns in the table represent the rate that an investor would have earned (or lost) on an investment in the Fund, assuming reinvestment of all dividends and distributions. This information has been audited by PricewaterhouseCoopers LLP, whose report is included, along with the Fund’s financial statements, in the Fund’s Annual Report (available upon request).

Supplemental Information

I. Premium/Discount Information

The table that follows presents information about the differences between the daily market price on secondary markets for shares of the Fund and the Fund’s NAV. NAV is the price at which the Fund issues and redeems shares. It is calculated in accordance with the standard formula for valuing mutual fund shares. The price used to calculate market returns (“Market Price”) of the Fund generally is determined using the midpoint between the highest bid and the lowest offer on the primary securities exchange on which shares of the Fund are listed for trading, as of the time that the Fund’s NAV is calculated. The Fund’s Market Price may be at, above or below its NAV. The NAV of the Fund will fluctuate with changes in the value of its portfolio holdings. The Market Price of the Fund will fluctuate in accordance with changes in its NAV, as well as market supply and demand.

Premiums or discounts are the differences (expressed as a percentage) between the NAV and Market Price of the Fund on a given day, generally at the time the NAV is calculated. A premium is the amount that the Fund is trading above the reported NAV, expressed as a percentage of the NAV. A discount is the amount that the Fund is trading below the reported NAV, expressed as a percentage of the NAV.

The following information shows the frequency of distributions of premiums and discounts for the Fund for each full calendar quarter of 2010 through September 30, 2011.

Each line in the table shows the number of trading days in which the Fund traded within the premium/discount range indicated. The number of trading days in each premium/discount range is also shown as a percentage of the total number of trading days in the period covered by the table. All data presented here represents past performance, which cannot be used to predict future results.

Premium/Discount Range

Less than -0.5% and Greater than -1.0% 6 1.36
Less than -1.0% 1 0.23
   441 100.00%

II. Total Return Information

The table that follows presents information about the total returns of the Fund and the Underlying Index as of the fiscal year ended July 31, 2011.

“Average Annual Total Returns” represent the average annual change in value of an investment over the periods indicated. “Cumulative Total Returns” represent the total change in value of an investment over the period indicated.

The Fund’s NAV is the value of one share of the Fund as calculated in accordance with the standard formula for valuing mutual fund shares. The NAV return is based on the NAV of the Fund and the market return is based on the Market Price of the Fund. Market Price is determined by using the midpoint between the highest bid and the lowest offer on the primary stock exchange on which shares of the Fund are listed for trading, as of the time that the Fund’s NAV is calculated. Since shares of the Fund did not trade in the secondary market until after the Fund’s inception, for the period from inception to the first day of secondary market trading in shares of the Fund, the NAV of the Fund is used as a proxy for the Market Price to calculate market returns. Market and NAV returns assume that dividends and capital gain distributions have been reinvested in the Fund at Market Price and NAV, respectively.

An index is a statistical composite that tracks a specified financial market or sector. Unlike the Fund, the Underlying Index does not actually hold a portfolio of securities and therefore does not incur the expenses incurred by the Fund. These expenses negatively impact the performance of the Fund. Also, market returns do not include brokerage commissions that may be payable on secondary market transactions. If brokerage commissions were included, market returns would be lower. The returns shown in the following table do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption or sale of Fund shares. The investment return and principal value of shares of the Fund will vary with changes in market conditions. Shares of the Fund may be worth more or less than their original cost when they are redeemed or sold in the market. The Fund’s past performance is no guarantee of future results.

Fund Overview

iSHARES® NYSE 100 INDEX FUND

Ticker: NY Stock Exchange: NYSE Arca

Investment Objective

The iShares NYSE 100 Index Fund (the “Fund”) seeks investment results that correspond generally to the price and yield performance, before fees and expenses, of the NYSE U.S. 100 Index (the “Underlying Index”).

Fees and Expenses

The following table describes the fees and expenses that you will incur if you own shares of the Fund. The investment advisory agreement between iShares Trust (the “Trust”) and BlackRock Fund Advisors (“BFA”) (the “Investment Advisory Agreement”) provides that BFA will pay all operating expenses of the Fund, except interest expenses, taxes, brokerage expenses, future distribution fees or expenses, and extraordinary expenses.

You may also incur usual and customary brokerage commissions when buying or selling shares of the Fund, which are not reflected in the example that follows:

Example. This Example is intended to help you compare the cost of owning shares of the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

Portfolio Turnover. The Fund may pay transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 7% of the average value of its portfolio.

Principal Investment Strategies

The Underlying Index is designed to measure the performance of the largest 100 U.S. companies, based on market capitalization, listed on the New York Stock Exchange (“NYSE”). As of September 30, 2011, these companies had a total market capitalization of approximately $5.41 trillion, which represents approximately 30.62% of the entire market capitalization of U.S.-registered equity securities and approximately 5.36% of all common stocks listed on the NYSE.

BFA uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to “beat” the index it tracks and does not seek temporary defensive positions when markets decline or appear overvalued.

Indexing may eliminate the chance that the Fund will substantially outperform the Underlying Index but also may reduce some of the risks of active management, such as poor security selection. Indexing seeks to achieve lower costs and better after-tax performance by keeping portfolio turnover low in comparison to actively managed investment companies.

BFA uses a representative sampling indexing strategy to manage the Fund. “Representative sampling” is an indexing strategy that involves investing in a representative sample of securities that collectively has an investment profile similar to the Underlying Index. The securities selected are expected to have, in the aggregate, investment characteristics (based on factors such as market capitalization and industry weightings), fundamental characteristics (such as return variability and yield) and liquidity measures similar to those of the Underlying Index. The Fund may or may not hold all of the securities in the Underlying Index.

The Fund generally invests at least 90% of its assets in securities of the Underlying Index and in depositary receipts representing securities of the Underlying Index. The Fund may invest the remainder of its assets in securities not included in the Underlying Index, but which BFA believes will help the Fund track the Underlying Index and in other investments including futures contracts, options on futures contracts, options and swaps as well as cash and cash equivalents, including shares of money market funds advised by BFA or its affiliates.

The Fund may lend securities representing up to one-third of the value of the Fund’s total assets (including the value of the collateral received).

The Underlying Index is sponsored by an organization (the “Index Provider”) that is independent of the Fund and BFA. The

S-2   


Table Of Contents



Index Provider determines the composition and relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index. The Fund’s Index Provider is NYSE Euronext.

Industry Concentration Policy. The Fund will concentrate its investments (i.e., hold 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. For purposes of this limitation, securities of the U.S. government (including its agencies and instrumentalities) and repurchase agreements collateralized by U.S. government securities are not considered to be issued by members of any industry.

Summary of Principal Risks

As with any investment, you could lose all or part of your investment in the Fund, and the Fund’s performance could trail that of other investments. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund’s net asset value per share (“NAV”), trading price, yield, total return and ability to meet its investment objective.

Asset Class Risk. Securities in the Underlying Index or in the Fund’s portfolio may underperform in comparison to the general securities markets or other asset classes.

Concentration Risk. To the extent that the Fund’s investments are concentrated in a particular issuer, region, country, market, industry or asset class, the Fund may be susceptible to loss due to adverse occurrences affecting that issuer, region, country, market, industry or asset class.

Consumer Goods Sector Risk. The consumer goods sector may be affected by changes in social trends and consumer demands. Many consumer goods are sold internationally and such companies are subject to market conditions in other countries and regions.

Equity Securities Risk. Equity securities are subject to changes in value and their values may be more volatile than other asset classes.

Financial Sector Risk. Performance of companies in the financial sector may be adversely impacted by many factors, including, among others, government regulations, economic conditions, credit rating downgrades, changes in interest rates, and decreased liquidity in credit markets. This sector has experienced significant losses in the recent past, and the impact of more stringent capital requirements and of recent or future regulation on any individual financial company or on the sector as a whole cannot be predicted.

Issuer Risk. Fund performance depends on the performance of individual securities to which the Fund has exposure. Changes to the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA’s investment management strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over

S-3   


Table Of Contents



longer periods during market downturns.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares, losses from trading in secondary markets, periods of high volatility and disruption in the creation/redemption process of the Fund. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV.

Oil and Gas Sector Risk. Companies in the oil and gas sector are affected by worldwide energy prices, exploration and production costs. Companies in the oil and gas sector may have significant operations in areas at risk for natural disasters, social unrest and environmental damage. These companies may also be at risk for increased government regulation and intervention, litigation, and negative publicity and perception.

Passive Investment Risk. The Fund is not actively managed and BFA does not attempt to take defensive positions under any market conditions, including declining markets.

Securities Lending Risk. The Fund may engage in securities lending. Securities lending involves the risk that the Fund may lose money because the borrower of the Fund’s loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Tracking Error Risk. The performance of the Fund may diverge from that of the Underlying Index. Because the Fund employs a representative sampling strategy, the Fund may experience tracking error to a greater extent than a fund that seeks to replicate an index.

1 After-tax returns in the table above are calculated using the historical highest individual U.S. federal marginal income tax rates and do not reflect the impact of state or local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown, and after-tax returns shown are not relevant to tax-exempt investors or investors who hold shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts (“IRAs”). Fund returns after taxes on distributions and sale of Fund shares are calculated assuming that an investor has sufficient capital gains of the same character from other investments to offset any capital losses from the sale of Fund shares. As a result, Fund returns after taxes on distributions and sale of Fund shares may exceed Fund returns before taxes and/or returns after taxes on distributions.

Management

Investment Adviser. BlackRock Fund Advisors.

Portfolio Managers. Rene Casis, Diane Hsiung and Greg Savage (the “Portfolio Managers”) are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager supervises a portfolio management team. Mr. Casis, Ms. Hsiung and Mr. Savage have been Portfolio Managers of the Fund since 2010, 2008 and 2008, respectively.

Purchase and Sale of Fund Shares

The Fund is an exchange-traded fund (commonly referred to as an “ETF”). Individual Fund shares may only be purchased and sold on a national securities exchange through a broker-dealer. The price of Fund shares is based on market price, and because ETF shares trade at market prices rather than NAV, shares may trade at a price greater than NAV (a premium) or less than NAV (a discount). The Fund will only issue or redeem shares that have been aggregated into blocks of 50,000 shares or multiples thereof (“Creation Units”) to authorized participants who have entered into agreements with the Fund’s distributor. The Fund generally will issue or redeem Creation Units in return for a designated portfolio of securities (and an amount of cash) that the Fund specifies each day.

Tax Information

The Fund intends to make distributions that may be taxable to you as ordinary income or capital gains, unless you are investing through a tax-deferred arrangement such as a 401(k) plan or an IRA.

Payments to Broker-Dealers and other Financial Intermediaries

If you purchase shares of the Fund through a broker-dealer or other financial intermediary (such as a bank), BFA or other related companies may pay the intermediary for marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems or other services related to the sale or promotion of the Fund. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.

More Information About the Fund

This Prospectus contains important information about investing in the Fund. Please read this Prospectus carefully before you make any investment decisions. Additional information regarding the Fund is available at www.iShares.com.

BFA is the investment adviser to the Fund. Shares of the Fund are listed for trading on NYSE Arca, Inc. (“NYSE Arca”). The market price for a share of the Fund may be different from the Fund’s most recent NAV.

ETFs are funds that trade like other publicly-traded securities. The Fund is designed to track an index. Similar to shares of an index mutual fund, each share of the Fund represents a partial ownership in an underlying portfolio of securities intended to track a market index. Unlike shares of a mutual fund, which can be bought and redeemed from the issuing fund by all shareholders at a price based on NAV, shares of the Fund may be purchased or redeemed directly from the Fund at NAV solely by authorized participants. Also unlike shares of a mutual fund, shares of the Fund are listed on a national securities exchange and trade in the secondary market at market prices that change throughout the day.

The Fund invests in a particular segment of the securities markets and seeks to track the performance of a securities index that generally is not representative of the market as a whole. The Fund is designed to be used as part of broader asset allocation strategies. Accordingly, an investment in the Fund should not constitute a complete investment program.

An index is a theoretical financial calculation while the Fund is an actual investment portfolio. The performance of the Fund and the Underlying Index may vary due to transaction costs, non-U.S. currency valuations, asset valuations, corporate actions (such as mergers and spin-offs), timing variances and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions (such as diversification requirements) that apply to the Fund but not to the Underlying Index or to the use of representative sampling. “Tracking error” is the difference between the performance (return) of the Fund’s portfolio and that of the Underlying Index. BFA expects that, over time, the Fund’s tracking error will not exceed 5%. Because the Fund uses a representative sampling indexing strategy, it can be expected to have a larger tracking error than if it used a replication indexing strategy. “Replication” is an indexing strategy in which a fund invests in substantially all of the securities in its underlying index in approximately the same proportions as in the underlying index.

An investment in the Fund is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, BFA or any of its affiliates.

The Fund’s investment objective and the Underlying Index may be changed without shareholder approval.

A Further Discussion of Principal Risks

The Fund is subject to various risks, including the principal risks noted below, any of which may adversely affect the Fund’s NAV, trading price, yield, total return and ability to meet its investment objective. You could lose all or part of your investment in the Fund, and the Fund could underperform other investments.

Asset Class Risk. The securities in the Underlying Index or in the Fund’s portfolio may underperform the returns of other securities or indexes that track other industries, groups of industries, markets, asset classes or sectors. Various types of securities or indexes tend to experience cycles of outperformance and underperformance in comparison to the general securities markets.

Concentration Risk. To the extent that the Fund’s portfolio reflects the Underlying Index’s concentration in the securities of a particular issuer or issuers in a particular country, group of countries, region, market, industry, group of industries, sector or asset class, the Fund may be adversely affected by the performance of those securities, may be subject to increased price volatility and may be more susceptible to adverse economic, market, political or regulatory occurrences affecting that issuer, country, group of countries, region, market, industry, group of industries, sector or asset class.

Consumer Goods Sector Risk. The consumer goods sector may be strongly affected by social trends, marketing campaigns and other factors affecting consumer demand. Governmental regulation affecting the use of various food additives may affect the profitability of certain companies represented in the Underlying Index. In addition, tobacco companies may be adversely affected by new laws, regulations and litigation. Many consumer goods in the United States may also be marketed globally, and such consumer goods companies may be affected by the demand and market conditions in non-U.S. countries.

Equity Securities Risk. The Fund invests in equity securities, which are subject to changes in value that may be attributable to market perception of a particular issuer or to general stock market fluctuations that affect all issuers. Investments in equity securities may be more volatile than investments in other asset classes.

Financial Sector Risk. Companies in the financial sector of an economy are often subject to governmental regulation and, recently, government intervention and the potential for additional regulation, which may adversely affect the scope of their activities, the prices they can charge and the amount of capital they must maintain. Governmental regulation may change frequently and may have significant adverse consequences for companies in the financial sector, including effects not intended by such regulation. The impact of recent or future regulation in various countries on any individual financial company or on the sector as a whole cannot be predicted. Certain risks may impact the value of investments in the financial sector more severely than investments outside this sector, including the risks associated with companies that operate with substantial financial leverage. Companies in the financial sector may also be adversely affected by increases in interest rates and loan losses, decreases in the availability of money or asset valuations, credit rating downgrades and adverse conditions in other related markets. Over the past few years, the deterioration of the

credit markets has impacted a broad range of mortgage, asset-backed, auction rate, sovereign debt and other markets, including U.S. and non-U.S. credit and interbank money markets, thereby affecting a wide range of financial institutions and markets. This situation has created instability in the financial markets and caused certain financial companies to incur large losses. Some financial companies have experienced declines in the valuations of their assets, taken actions to raise capital (such as the issuance of debt or equity securities), or even ceased operations. Some financial companies have borrowed significant amounts of capital from governments and may face future government-imposed restrictions on their businesses or increased government intervention. These actions have caused the securities of many financial companies to decline in value. Insurance companies, in particular, may be subject to severe price competition, which may have an adverse impact on their profitability.

Issuer Risk. The performance of the Fund depends on the performance of individual securities to which the Fund has exposure. Any issuer of these securities may perform poorly, causing the value of its securities to decline. Poor performance may be caused by poor management decisions, competitive pressures, changes in technology, expiration of patent protection, disruptions in supply, labor problems or shortages, corporate restructurings, fraudulent disclosures or other factors. Issuers may, in times of distress or at their own discretion, decide to reduce or eliminate dividends, which may also cause their stock prices to decline.

Management Risk. The Fund may not fully replicate the Underlying Index and may hold securities not included in the Underlying Index. As a result, the Fund is subject to the risk that BFA’s investment management strategy, the implementation of which is subject to a number of constraints, may not produce the intended results.

Market Risk. The Fund could lose money due to short-term market movements and over longer periods during market downturns. Securities may decline in value due to factors affecting securities markets generally or particular industries represented in the markets. The value of a security may decline due to general market conditions, economic trends or events that are not specifically related to the issuer of the security or to factors that affect a particular industry or industries. During a general downturn in the securities markets, multiple asset classes may be negatively affected.

Market Trading Risk

Absence of Active Market. Although shares of the Fund are listed for trading on one or more stock exchanges, there can be no assurance that an active trading market for such shares will develop or be maintained.

Risk of Secondary Listings. The Fund’s shares may be listed or traded on U.S. and non-U.S. stock exchanges other than the U.S. stock exchange where the Fund’s primary listing is maintained. There can be no assurance that the Fund’s shares will continue to trade on any such stock exchange or in any market or that the Fund’s shares will continue to meet the requirements for listing or trading on any exchange or in any market. The Fund’s shares may be less actively traded in certain markets than others, and investors are subject to the execution and settlement risks and market standards of the market where they or their broker direct their trades for execution. Certain information available to investors who trade Fund shares on a U.S. stock exchange

during regular U.S. market hours may not be available to investors who trade in other markets, which may result in secondary market prices in such markets being less efficient.

Secondary Market Trading Risk. Shares of the Fund may trade in the secondary market at times when the Fund does not accept orders to purchase or redeem shares. At such times, shares may trade in the secondary market with more significant premiums or discounts than might be experienced at times when the Fund accepts purchase and redemption orders.

Secondary market trading in Fund shares may be halted by a stock exchange because of market conditions or other reasons. In addition, trading in Fund shares on a stock exchange or in any market may be subject to trading halts caused by extraordinary market volatility pursuant to “circuit breaker” rules on the stock exchange or market. There can be no assurance that the requirements necessary to maintain the listing or trading of Fund shares will continue to be met or will remain unchanged.

Shares of the Fund May Trade at Prices Other Than NAV. Shares of the Fund trade on stock exchanges at prices at, above or below their most recent NAV. The NAV of the Fund is calculated at the end of each business day and fluctuates with changes in the market value of the Fund’s holdings since the most recent calculation. The trading prices of the Fund’s shares fluctuate continuously throughout trading hours based on market supply and demand rather than NAV. The trading prices of the Fund’s shares may deviate significantly from NAV during periods of market volatility. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV. However, because shares can be created and redeemed in Creation Units at NAV (unlike shares of many closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their NAVs), BFA believes that large discounts or premiums to the NAV of the Fund are not likely to be sustained over the long-term. While the creation/redemption feature is designed to make it likely that the Fund’s shares normally will trade on stock exchanges at prices close to the Fund’s next calculated NAV, exchange prices are not expected to correlate exactly with the Fund’s NAV due to timing reasons as well as market supply and demand factors. In addition, disruptions to creations and redemptions or extreme market volatility may result in trading prices for shares of the Fund that differ significantly from its NAV.

Costs of Buying or Selling Fund Shares. Buying or selling Fund shares on an exchange involves two types of costs that apply to all securities transactions. When buying or selling shares of the Fund through a broker, you will likely incur a brokerage commission or other charges imposed by brokers as determined by that broker. In addition, you may incur the cost of the “spread” – that is, the difference between what investors are willing to pay for Fund shares (the “bid” price) and the price at which they are willing to sell Fund shares (the “ask” price). Because of the costs inherent in buying or selling Fund shares, frequent trading may detract significantly from investment results and an investment in Fund shares may not be advisable for investors who anticipate regularly making small investments.

Oil and Gas Sector Risk. The profitability of companies in the oil and gas sector is related to worldwide energy prices, exploration, and production spending. Companies

in the oil and gas sector may be adversely affected by natural disasters or other catastrophes. Companies in the oil and gas sector may be at risk for environmental damage claims and other types of litigation. Companies in the oil and gas sector may be adversely affected by changes in exchange rates, interest rates, changes in prices for competitive energy services, economic conditions, tax treatment, government regulation and intervention, negative perception and world events in the regions where companies operate (e.g., expropriation, nationalization, confiscation of assets and property or imposition of restrictions on foreign investments and repatriation of capital, military coups, social unrest, violence or labor unrest). Companies in the oil and gas sector may have significant capital investments in, or engage in transactions involving, emerging market countries, which may heighten these risks.

Passive Investment Risk. The Fund is not actively managed and may be affected by a general decline in market segments related to the Underlying Index. The Fund invests in securities included in, or representative of, the Underlying Index regardless of their investment merits. BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

Securities Lending Risk. The Fund may engage in securities lending. Securities lending involves the risk that the Fund may lose money because the borrower of the Fund’s loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for the loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Tracking Error Risk. Imperfect correlation between the Fund’s portfolio securities and those in the Underlying Index, rounding of prices, changes to the Underlying Index and regulatory requirements may cause tracking error, which is the divergence of the Fund’s performance from that of the Underlying Index. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Underlying Index does not. Because the Fund employs a representative sampling strategy, the Fund may experience tracking error to a greater extent than a fund that seeks to replicate an index.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

Consumer Services Sector Risk. The success of consumer product manufacturers and retailers (including food and drug retailers, general retailers, media, and travel and leisure) is tied closely to the performance of the domestic and international economy, interest rates, exchange rates, competition and consumer confidence. The consumer services sector depends heavily on disposable household income and consumer spending. Companies in the consumer services sector may be subject to severe competition, which may also have an adverse impact on their profitability. Changes in demographics and consumer preferences may affect the success of consumer products.

Health Care Sector Risk. The profitability of companies in the health care sector may be affected by extensive government regulations, restrictions on government reimbursement for medical expenses, rising costs of medical products and services, pricing pressure, an increased emphasis on outpatient services, limited number of products, industry innovation, changes in technologies and other market developments. Many health care companies are heavily dependent on patent protection. The expiration of patents may adversely affect the profitability of these companies. Many health care companies are subject to extensive litigation based on product liability and similar claims. Health care companies are subject to competitive forces that may make it difficult to raise prices and, in fact, may result in price discounting. Many new products in the health care sector may be subject to regulatory approvals. The process of obtaining such approvals may be long and costly. Companies in the health care sector may be thinly capitalized and may be susceptible to product obsolescence.

Industrials Sector Risk. The stock prices of companies in the industrials sector are affected by supply and demand, both for their specific product or service and for industrials sector products in general. The products of manufacturing companies may face obsolescence due to rapid technological developments and frequent new product introduction. Government regulations, world events, economic conditions and exchange rates affect the performance of companies in the industrials sector. Companies in the industrials sector may be adversely affected by liability for environmental damage and product liability claims.

Telecommunications Sector Risk. The telecommunications sector is subject to extensive government regulation. The costs of complying with governmental regulations, delays or failure to receive required regulatory approvals, or the enactment of new adverse regulatory requirements may negatively affect the business of the telecommunications companies. Government actions around the world, specifically in the area of pre-marketing clearance of products and prices, can be arbitrary and unpredictable. Companies in the telecommunications sector may encounter distressed cash flows due to the need to commit substantial capital to meet increasing competition, particularly in formulating new products and services using new technology. Technological innovations may make the products and services of telecommunications companies obsolete.

Technology Sector Risk. The Fund invests in technology companies, which face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Technology companies may have limited product lines, markets, financial resources or personnel. The products of technology companies may face obsolescence due to rapid technological developments and frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Companies in the technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies.

Management

Investment Adviser. As investment adviser, BFA has overall responsibility for the general management and administration of the Trust. BFA provides an investment program for the Fund and manages the investment of the Fund’s assets. In managing the Fund, BFA may draw upon the research and expertise of its asset management affiliates with respect to certain portfolio securities. In seeking to achieve the Fund’s investment objective, BFA uses teams of portfolio managers, investment strategists and other investment specialists. This team approach brings together many disciplines and leverages BFA’s extensive resources.

Pursuant to the Investment Advisory Agreement between BFA and the Trust (entered into on behalf of the Fund), BFA is responsible for substantially all expenses of the Fund, except interest expenses, taxes, brokerage expenses, future distribution fees or expenses and extraordinary expenses.

For its investment advisory services to the Fund, BFA is entitled to receive a management fee from the Fund based on a percentage of the Fund’s average daily net assets, at the annual rate of 0.20%.

BFA is located at 400 Howard Street, San Francisco, CA 94105. It is a wholly owned subsidiary of BTC, which in turn is indirectly wholly-owned by BlackRock, Inc. (“BlackRock”). As of September 30, 2011, BTC and its affiliates, including BFA and BlackRock, provided investment advisory services for assets in excess of $3.35 trillion. BFA, BTC, BlackRock Execution Services, BlackRock and their affiliates deal, trade and invest for their own accounts in the types of securities in which the Fund may also invest.

A discussion regarding the basis for the Trust’s Board of Trustees’ (the “Board”) approval of the Investment Advisory Agreement with BFA is available in the Fund’s annual report for the period ended July 31.

Portfolio Managers. Rene Casis, Diane Hsiung and Greg Savage are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager is responsible for various functions related to portfolio management, including, but not limited to, investing cash inflows, coordinating with members of his or her portfolio management team to focus on certain asset classes, implementing investment strategy, researching and reviewing investment strategy and overseeing members of his or her portfolio management team that have more limited responsibilities.

Rene Casis has been employed by BFA (formerly, Barclays Global Fund Advisors (“BGFA”)) and BTC (formerly, Barclays Global Investors, N.A. (“BGI”)) as a senior portfolio manager since 2009. From 2005 to 2009, Mr. Casis was a trader at Barclays

Capital. Prior to that, Mr. Casis was a portfolio manager from 2000 to 2005 for BGFA and BGI. Mr. Casis has been a Portfolio Manager of the Fund since 2010.

Diane Hsiung has been employed by BFA and BTC as a senior portfolio manager since 2007. Prior to that, Ms. Hsiung was a portfolio manager from 2002 to 2006 for BGFA and BGI. Ms. Hsiung has been a Portfolio Manager of the Fund since 2008.

Greg Savage has been employed by BFA and BTC as a senior portfolio manager since 2006. Prior to that, Mr. Savage was a portfolio manager from 2001 to 2006 for BGFA and BGI. Mr. Savage has been a Portfolio Manager of the Fund since 2008.

The Fund’s SAI provides additional information about the Portfolio Managers’ compensation, other accounts managed by the Portfolio Managers and the Portfolio Managers’ ownership (if any) of shares in the Fund.

Administrator, Custodian and Transfer Agent. State Street Bank and Trust Company (“State Street”) is the administrator, custodian and transfer agent for the Fund.

Conflicts of Interest. BFA wants you to know that there are certain entities with which BFA has relationships that may give rise to conflicts of interest, or the appearance of conflicts of interest. These entities include the following: BFA’s affiliates (including BlackRock and The PNC Financial Services Group, Inc., and each of their affiliates, directors, partners, trustees, managing members, officers and employees (collectively, the “Affiliates”)) and BlackRock’s significant shareholder, Barclays Bank PLC and its affiliates, including Barclays PLC (each, an “Entity” and together, the “Entities”).

The activities of BFA, the Affiliates and the Entities in the management of, or their interest in, their own accounts and other accounts they manage, may present conflicts of interest that could disadvantage the Fund and its shareholders. BFA and its Affiliates or the Entities provide investment management services to other funds and discretionary managed accounts that may follow an investment program similar to that of the Fund. BFA, its Affiliates and the Entities are involved worldwide with a broad spectrum of financial services and asset management activities and may engage in the ordinary course of business in activities in which their interests or the interests of their clients may conflict with those of the Fund. BFA, one or more of the Affiliates or the Entities acts, or may act, as an investor, investment banker, research provider, investment manager, financier, underwriter, advisor, market maker, trader, prime broker, lender, agent or principal, and have other direct and indirect interests, in securities, currencies and other instruments in which the Fund may directly or indirectly invest. Thus, it is likely that the Fund will have multiple business relationships with and will invest in, engage in transactions with, make voting decisions with respect to, or obtain services from, entities for which BFA, an Affiliate or an Entity performs or seeks to perform investment banking or other services.

BFA or one or more Affiliates or Entities may engage in proprietary trading and advise accounts and funds that have investment objectives similar to those of the Fund and/or that engage in and compete for transactions in the same types of securities, currencies and other instruments as the Fund, including in securities issued by other open-end and closed-end investment management companies, including investment

companies that are affiliated with the Fund and BFA, to the extent permitted under the Investment Company Act of 1940, as amended (the “1940 Act”). The trading activities of BFA, these Affiliates and Entities are carried out without reference to positions held directly or indirectly by the Fund and may result in BFA, an Affiliate or an Entity having positions that are adverse to those of the Fund.

No Affiliate or Entity is under any obligation to share any investment opportunity, idea or strategy with the Fund. As a result, an Affiliate or an Entity may compete with the Fund for appropriate investment opportunities. As a result of this and several other factors, the results of the Fund’s investment activities may differ from those of an Affiliate or an Entity and of other accounts managed by an Affiliate or an Entity, and it is possible that the Fund could sustain losses during periods in which one or more Affiliates or Entities and other accounts achieve profits on their trading for proprietary or other accounts. The opposite result is also possible.

The Fund may, from time to time, enter into transactions in which BFA or an Affiliate’s or an Entity’s clients have an interest adverse to the Fund. Furthermore, transactions undertaken by Affiliate-advised clients may adversely impact the Fund. Transactions by one or more Affiliate- or Entity-advised clients or BFA may have the effect of diluting or otherwise disadvantaging the values, prices or investment strategies of the Fund.

An Entity may maintain securities indices as part of its product offerings. Index-based funds seek to track the performance of securities indices and may use the name of the index in the fund name. Index providers, including the Entities, may be paid licensing fees for use of their indices or index names. Entities will not be obligated to license their indices to BFA and its Affiliates, and BFA and its Affiliates will not be assured that the terms of any index licensing agreement with the Entities will be as favorable as those terms offered to other index licensees.

The Fund’s activities may be limited because of regulatory restrictions applicable to one or more Affiliates or Entities, and/or their internal policies designed to comply with such restrictions. In addition, the Fund may invest in securities of companies with which an Affiliate or an Entity has or is trying to develop investment banking relationships or in which an Affiliate or an Entity has significant debt or equity investments. The Fund also may invest in securities of companies for which an Affiliate or an Entity provides or may some day provide research coverage. An Affiliate or an Entity may have business relationships with and purchase or distribute or sell services or products from or to distributors, consultants or others who recommend the Fund or who engage in transactions with or for the Fund, and may receive compensation for such services. The Fund may also make brokerage and other payments to Affiliates or Entities in connection with the Fund’s portfolio investment transactions.

Pursuant to a securities lending program approved by the Board, the Fund has retained an Affiliate of BFA to serve as the securities lending agent for the Fund to the extent that the Fund participates in the securities lending program. For these services, the lending agent may receive a fee from the Fund, including a fee based on the returns earned on the Fund’s investment of the cash received as collateral for any loaned securities. In addition, one or more Affiliates may be among the entities to which the Fund may lend its portfolio securities under the securities lending program.

The activities of BFA, the Affiliates or Entities may give rise to other conflicts of interest that could disadvantage the Fund and its shareholders. BFA has adopted policies and procedures designed to address these potential conflicts of interest. See the Fund’s SAI for further information.

Shareholder Information

Additional shareholder information, including how to buy and sell shares of the Fund, is available free of charge by calling toll-free: 1-800-iShares (1-800-474-2737) or visiting our website at www.iShares.com.

Buying and Selling Shares. Shares of the Fund may be acquired or redeemed directly from the Fund only in Creation Units or multiples thereof, as discussed in the Creations and Redemptions section of this Prospectus. Only an Authorized Participant (as defined in the Creations and Redemptions section) may engage in creation or redemption transactions directly with the Fund. Once created, shares of the Fund generally trade in the secondary market in amounts less than a Creation Unit.

Shares of the Fund are listed on a national securities exchange for trading during the trading day. Shares can be bought and sold throughout the trading day like shares of other publicly-traded companies. The Trust does not impose any minimum investment for shares of the Fund purchased on an exchange. The Fund’s shares trade under the trading symbol “NY.”

Buying or selling Fund shares on an exchange involves two types of costs that may apply to all securities transactions. When buying or selling shares of the Fund through a broker, you will likely incur a brokerage commission or other charges determined by your broker. The commission is frequently a fixed amount and may be a significant proportional cost for investors seeking to buy or sell small amounts of shares. In addition, you may incur the cost of the “spread” – that is, any difference between the bid price and the ask price. The spread varies over time for shares of the Fund based on its trading volume and market liquidity, and is generally lower if the Fund has a lot of trading volume and market liquidity, and higher if the Fund has little trading volume and market liquidity.

The Board has adopted a policy of not monitoring for frequent purchases and redemptions of Fund shares (“frequent trading”) that appear to attempt to take advantage of a potential arbitrage opportunity presented by a lag between a change in the value of the Fund’s portfolio securities after the close of the primary markets for the Fund’s portfolio securities and the reflection of that change in the Fund’s NAV (“market timing”), because the Fund generally sells and redeems its shares directly through transactions that are in-kind and/or for cash, subject to the conditions described below under Creations and Redemptions. The Board has not adopted a policy of monitoring for other frequent trading activity because shares of the Fund are listed for trading on a national securities exchange.

The national securities exchange on which the Fund’s shares are listed is open for trading Monday through Friday and is closed on weekends and the following holidays: New Year’s Day, Martin Luther King, Jr. Day, Presidents’ Day, Good Friday, Memorial

Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day. The Fund’s primary listing exchange is NYSE Arca.

Section 12(d)(1) of the 1940 Act restricts investments by investment companies in the securities of other investment companies. Registered investment companies are permitted to invest in the Fund beyond the limits set forth in Section 12(d)(1), subject to certain terms and conditions set forth in SEC rules or in an SEC exemptive order issued to the Trust. In order for a registered investment company to invest in shares of the Fund beyond the limitations of Section 12(d)(1) pursuant to the exemptive relief obtained by the Trust, the registered investment company must enter into an agreement with the Trust.

Book Entry. Shares of the Fund are held in book-entry form, which means that no stock certificates are issued. The Depository Trust Company (“DTC”) or its nominee is the record owner of all outstanding shares of the Fund and is recognized as the owner of all shares for all purposes.

Investors owning shares of the Fund are beneficial owners as shown on the records of DTC or its participants. DTC serves as the securities depository for shares of the Fund. DTC participants include securities brokers and dealers, banks, trust companies, clearing corporations and other institutions that directly or indirectly maintain a custodial relationship with DTC. As a beneficial owner of shares, you are not entitled to receive physical delivery of stock certificates or to have shares registered in your name, and you are not considered a registered owner of shares. Therefore, to exercise any right as an owner of shares, you must rely upon the procedures of DTC and its participants. These procedures are the same as those that apply to any other securities that you hold in book-entry or “street name” form.

Share Prices. The trading prices of the Fund’s shares in the secondary market generally differ from the Fund’s daily NAV and are affected by market forces such as supply and demand, economic conditions and other factors. Information regarding the intraday value of shares of the Fund, also known as the “indicative optimized portfolio value” (“IOPV”), is disseminated every 15 seconds throughout the trading day by the national securities exchange on which the Fund’s shares are listed or by market data vendors or other information providers. The IOPV is based on the current market value of the securities and/or cash required to be deposited in exchange for a Creation Unit. The IOPV does not necessarily reflect the precise composition of the current portfolio of securities held by the Fund at a particular point in time or the best possible valuation of the current portfolio. Therefore, the IOPV should not be viewed as a “real-time” update of the Fund’s NAV, which is computed only once a day. The IOPV is generally determined by using both current market quotations and/or price quotations obtained from broker-dealers that may trade in the portfolio securities held by the Fund. The quotations of certain Fund holdings may not be updated during U.S. trading hours if such holdings do not trade in the United States. The Fund is not involved in, or responsible for, the calculation or dissemination of the IOPV and makes no representation or warranty as to its accuracy.

Determination of Net Asset Value. The NAV of the Fund normally is determined once daily Monday through Friday, generally as of the regularly scheduled close of business of the NYSE (normally 4:00 p.m., Eastern time) on each day that the NYSE is

open for trading, based on prices at the time of closing provided that (a) any Fund assets or liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers (as detailed below) and (b) U.S. fixed income assets may be valued as of the announced closing time for trading in fixed income instruments in a particular market or exchange. The NAV of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets held by the Fund, and its liabilities, are determined pursuant to valuation policies and procedures approved by the Board. The Fund’s assets and liabilities are valued primarily on the basis of market quotations.

Equity investments are valued at market value, which is generally determined using the last reported official closing price or last trading price on the exchange or market on which the security is primarily traded at the time of valuation.

Generally, trading in foreign securities, U.S. government securities, money market instruments and certain fixed-income securities is substantially completed each day at various times prior to the close of business on the NYSE. The values of such securities used in computing the NAV of the Fund are determined as of such times.

When market quotations are not readily available or are believed by BFA to be unreliable, the Fund’s investments are valued at fair value. Fair value determinations are made by BFA in accordance with policies and procedures approved by the Fund’s Board. BFA may conclude that a market quotation is not readily available or is unreliable if a security or other asset or liability does not have a price source due to its lack of liquidity, if a market quotation differs significantly from recent price quotations or otherwise no longer appears to reflect fair value, where the security or other asset or liability is thinly traded, or where there is a significant event subsequent to the most recent market quotation. A “significant event” is an event that, in the judgment of BFA, is likely to cause a material change to the closing market price of the asset or liability held by the Fund. Foreign securities whose values are affected by volatility that occurs in U.S. markets on a trading day after the close of foreign securities markets may be fair valued.

Fair value represents a good faith approximation of the value of an asset or liability. The fair value of an asset or liability held by the Fund is the amount the Fund might reasonably expect to receive from the current sale of that asset or the cost to extinguish that liability in an arm’s-length transaction. Valuing the Fund’s investments using fair value pricing will result in prices that may differ from current market valuations and that may not be the price at which those investments could have been sold during the period in which the particular fair values were used. Use of fair value prices and certain current market valuations could result in a difference between the prices used to calculate the Fund’s NAV and the prices used by the Underlying Index, which, in turn, could result in a difference between the Fund’s performance and the performance of the Underlying Index.

Dividends and Distributions

General Policies. Dividends from net investment income, if any, generally are declared and paid quarterly by the Fund. Distributions of net realized securities gains, if any, generally are declared and paid once a year, but the Trust may make distributions on a more frequent basis for the Fund. The Trust reserves the right to declare special distributions if, in its reasonable discretion, such action is necessary or advisable to preserve its status as a regulated investment company (“RIC”) or to avoid imposition of income or excise taxes on undistributed income or realized gains.

Dividends and other distributions on shares of the Fund are distributed on a pro rata basis to beneficial owners of such shares. Dividend payments are made through DTC participants and indirect participants to beneficial owners then of record with proceeds received from the Fund.

Dividend Reinvestment Service. No dividend reinvestment service is provided by the Trust. Broker-dealers may make available the DTC book-entry Dividend Reinvestment Service for use by beneficial owners of the Fund for reinvestment of their dividend distributions. Beneficial owners should contact their broker to determine the availability and costs of the service and the details of participation therein. Brokers may require beneficial owners to adhere to specific procedures and timetables. If this service is available and used, dividend distributions of both income and realized gains will be automatically reinvested in additional whole shares of the Fund purchased in the secondary market.

Taxes. As with any investment, you should consider how your investment in shares of the Fund will be taxed. The tax information in this Prospectus is provided as general information, based on current law. You should consult your own tax professional about the tax consequences of an investment in shares of the Fund.

Unless your investment in Fund shares is made through a tax-exempt entity or tax-deferred retirement account, such as an IRA, you need to be aware of the possible tax consequences when the Fund makes distributions or you sell Fund shares.

Taxes on Distributions. Distributions from the Fund’s net investment income (other than qualified dividend income), including distributions of income from securities lending and distributions out of the Fund’s net short-term capital gains, if any, are taxable to you as ordinary income. Distributions by the Fund of net long-term capital gains in excess of net short-term capital losses (capital gain dividends) are taxable to you as long-term capital gains, generally at a 15% tax rate (0% at certain income levels), regardless of how long you have held the Fund’s shares. Distributions by the Fund that qualify as qualified dividend income are taxable to you at long-term capital gain rates for taxable years beginning on or before December 31, 2012. The 15% and 0% tax rates expire for taxable years beginning after December 31, 2012. Maximum long-term capital gain income tax rates are scheduled to rise to 20% in 2013. Beginning in 2013, a 3.8% U.S. federal Medicare contribution tax will be imposed on “net investment income,” including interest, dividends, and capital gains, of U.S. individuals with income exceeding $200,000 (or $250,000 if married and filing jointly), and of estates and trusts.

Dividends will be qualified dividend income to you if they are attributable to qualified dividend income received by the Fund. Generally, qualified dividend income includes dividend income from taxable U.S. corporations, provided that the Fund satisfies certain holding period requirements in respect of the stock of such corporations and has not hedged its position in the stock in certain ways. Substitute dividends received by the Fund with respect to dividends paid on securities lent out will not be qualified dividend income.

Dividends received by the Fund from a real estate investment trust (“REIT”) or another RIC generally are qualified dividend income only to the extent the dividend distributions are made out of qualified dividend income received by such REIT or RIC. It is expected that dividends received by the Fund from a REIT and distributed to a shareholder generally will be taxable to the shareholder as ordinary income.

For a dividend to be treated as qualified dividend income, the dividend must be received with respect to a share of stock held without being hedged by the Fund, and with respect to a share of the Fund held without being hedged by you, for 61 days during the 121-day period beginning at the date which is 60 days before the date on which such share becomes ex-dividend with respect to such dividend or, in the case of certain preferred stock, 91 days during the 181-day period beginning 90 days before such date.

If your Fund shares are loaned out pursuant to a securities lending arrangement, you may lose the ability to use foreign tax credits passed through by the Fund or to treat Fund dividends paid while the shares are held by the borrower as qualified dividend income.

In general, your distributions are subject to U.S. federal income tax for the year when they are paid. Certain distributions paid in January, however, may be treated as paid on December 31 of the prior year.

If the Fund’s distributions exceed current and accumulated earnings and profits, all or a portion of the distributions made in the taxable year may be recharacterized as a return of capital to shareholders. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and result in a higher capital gain or lower capital loss when those shares on which the distribution was received are sold. Once a shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain, if the shareholder holds shares of the Fund as capital assets.

If you are neither a resident nor a citizen of the United States or if you are a non-U.S. entity, the Fund’s ordinary income dividends (which include distributions of net short-term capital gains) will generally be subject to a 30% U.S. withholding tax, unless a lower treaty rate applies, provided that withholding tax will generally not apply to any gain or income realized by a non-U.S. shareholder in respect of any distributions of long-term capital gains or upon the sale or other disposition of shares of the Fund.

A 30% withholding tax will be imposed on dividends paid after December 31, 2013, and redemption proceeds paid after December 31, 2014, to (i) foreign financial institutions including non-U.S. investment funds unless they agree to collect and disclose to the Internal Revenue Service (“IRS”) information regarding their direct and indirect U.S. account holders and (ii) certain other foreign entities, unless they certify certain

information regarding their direct and indirect U.S. owners. To avoid withholding, foreign financial institutions will need to enter into agreements with the IRS that state that they will provide the IRS information, including the name, address and taxpayer identification number of direct and indirect U.S. account holders, comply with due diligence procedures with respect to the identification of U.S. accounts, report to the IRS certain information with respect to U.S. accounts maintained, agree to withhold tax on certain payments made to non-compliant foreign financial institutions or to account holders who fail to provide the required information, and determine certain other information as to their account holders. Other foreign entities will need to provide the name, address, and taxpayer identification number of each substantial U.S. owner or certifications of no substantial U.S. ownership unless certain exceptions apply.

If you are a resident or a citizen of the United States, by law, back-up withholding will apply to your distributions and proceeds if you have not provided a taxpayer identification number or social security number and made other required certifications.

Taxes When Shares are Sold. Currently, any capital gain or loss realized upon a sale of Fund shares is generally treated as a long-term gain or loss if the shares have been held for more than one year. Any capital gain or loss realized upon a sale of Fund shares held for one year or less is generally treated as short-term gain or loss, except that any capital loss on the sale of shares held for six months or less is treated as long-term capital loss to the extent that capital gain dividends were paid with respect to such shares. Beginning in 2013, any such capital gains, including from sales of Fund shares or from capital gain dividends, will be included in “net investment income” for purposes of the 3.8% U.S. federal Medicare contribution tax mentioned above.

The foregoing discussion summarizes some of the consequences under current U.S. federal tax law of an investment in the Fund. It is not a substitute for personal tax advice. You may also be subject to state and local taxation on Fund distributions and sales of shares. Consult your personal tax adviser about the potential tax consequences of an investment in shares of the Fund under all applicable tax laws.

Creations and Redemptions. Prior to trading in the secondary market, shares of the Fund are “created” at NAV by market makers, large investors and institutions only in block-size Creation Units of 50,000 shares or multiples thereof. Each “creator” or “Authorized Participant” enters into an authorized participant agreement with the Fund’s distributor, SEI Investments Distribution Co. (the “Distributor”). Only an Authorized Participant may create or redeem Creation Units directly with the Fund. A creation transaction, which is subject to acceptance by the transfer agent, generally takes place when an Authorized Participant deposits into the Fund a designated portfolio of securities and a specified amount of cash approximating the holdings of the Fund in exchange for a specified number of Creation Units. To the extent practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund.

Similarly, shares can be redeemed only in Creation Units, generally for a designated portfolio of securities and a specified amount of cash held by the Fund (“Fund Securities”). Except when aggregated in Creation Units, shares are not redeemable by the Fund. The prices at which creations and redemptions occur are based on the next

calculation of NAV after an order is received in a form described in the authorized participant agreement.

The Fund intends to comply with the U.S. federal securities laws in accepting securities for deposit and satisfying redemptions with redemption securities by, among other means, assuring that any securities accepted for deposit and any securities used to satisfy redemption requests will be sold in transactions that would be exempt from registration under the Securities Act of 1933, as amended (the “1933 Act”). Further, an Authorized Participant that is not a “qualified institutional buyer,” as such term is defined under Rule 144A of the 1933 Act, will not be able to receive Fund Securities that are restricted securities eligible for resale under Rule 144A.

Creations and redemptions must be made through a firm that is either a member of the Continuous Net Settlement System of the National Securities Clearing Corporation or a DTC participant and has executed an agreement with the Distributor with respect to creations and redemptions of Creation Unit aggregations. Information about the procedures regarding creation and redemption of Creation Units (including the cut-off times for receipt of creation and redemption orders) is included in the Fund’s SAI.

Because new shares may be created and issued on an ongoing basis, at any point during the life of the Fund a “distribution,” as such term is used in the 1933 Act, may be occurring. Broker-dealers and other persons are cautioned that some activities on their part may, depending on the circumstances, result in their being deemed participants in a distribution in a manner that could render them statutory underwriters and subject to the prospectus delivery and liability provisions of the 1933 Act. Any determination of whether one is an underwriter must take into account all the relevant facts and circumstances of each particular case.

Broker-dealers should also note that dealers who are not “underwriters” but are participating in a distribution (as contrasted to ordinary secondary transactions), and thus dealing with shares that are part of an “unsold allotment” within the meaning of Section 4(3)(C) of the 1933 Act, would be unable to take advantage of the prospectus delivery exemption provided by Section 4(3) of the 1933 Act. For delivery of prospectuses to exchange members, the prospectus delivery mechanism of Rule 153 under the 1933 Act is available only with respect to transactions on a national securities exchange.

Costs Associated with Creations and Redemptions. Authorized Participants are charged standard creation and redemption transaction fees to offset transfer and other transaction costs associated with the issuance and redemption of Creation Units. The standard creation and redemption transaction fees are set forth in the table below. The standard creation transaction fee is charged to the Authorized Participant on the day such Authorized Participant creates a Creation Unit, and is the same regardless of the number of Creation Units purchased by the Authorized Participant on the applicable business day. Similarly, the standard redemption transaction fee is charged to the Authorized Participant on the day such Authorized Participant redeems a Creation Unit, and is the same regardless of the number of Creation Units redeemed by the Authorized Participant on the applicable business day. Creations and redemptions for cash (when cash creations and redemptions (in whole or in part) are available or specified) are also subject to an additional charge (up to the maximum

amounts shown in the table below). This charge is intended to compensate for brokerage, tax, foreign exchange, execution, market impact and other costs and expenses related to cash transactions. Investors who use the services of a broker or other financial intermediary may pay fees for such services.

The following table shows, as of September 30, 2011, the approximate value of one Creation Unit, standard fees and maximum additional charges for creations and redemptions (as described above):

Householding. Householding is an option available to certain Fund investors. Householding is a method of delivery, based on the preference of the individual investor, in which a single copy of certain shareholder documents can be delivered to investors who share the same address, even if their accounts are registered under different names. Please contact your broker-dealer if you are interested in enrolling in householding and receiving a single copy of prospectuses and other shareholder documents, or if you are currently enrolled in householding and wish to change your householding status.

Distribution

The Distributor distributes Creation Units for the Fund on an agency basis. The Distributor does not maintain a secondary market in shares of the Fund. The Distributor has no role in determining the policies of the Fund or the securities that are purchased or sold by the Fund. The Distributor’s principal address is One Freedom Valley Drive, Oaks, PA 19456.

In addition, BFA or its Affiliates make payments to broker-dealers, banks or other financial intermediaries (together, “intermediaries”) related to marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems, or their making shares of the Fund and certain other iShares funds available to their customers. Such payments, which may be significant to the intermediary, are not made by the Fund. Rather, such payments are made by BFA or its Affiliates from their own resources, which come directly or indirectly in part from fees paid by the iShares funds complex. Payments of this type are sometimes referred to as revenue-sharing payments. A financial intermediary may make decisions about which investment options it recommends or makes available, or the level of services provided, to its customers based on the revenue-sharing payments it is eligible to receive. Therefore, such payments to an intermediary create conflicts of interest between the intermediary and its customers and may cause the intermediary to recommend the Fund or other iShares funds over another investment.

More information regarding these payments is contained in the Fund’s SAI. Please contact your salesperson or other investment professional for more information regarding any such payments his or her firm may receive from BFA or its Affiliates.

Financial Highlights

The financial highlights table is intended to help investors understand the Fund’s financial performance for the past five years. Certain information reflects financial results for a single share of the Fund. The total returns in the table represent the rate that an investor would have earned (or lost) on an investment in the Fund, assuming reinvestment of all dividends and distributions. This information has been audited by PricewaterhouseCoopers LLP, whose report is included, along with the Fund’s financial statements, in the Fund’s Annual Report (available upon request).

Supplemental Information

I. Premium/Discount Information

The table that follows presents information about the differences between the daily market price on secondary markets for shares of the Fund and the Fund’s NAV. NAV is the price at which the Fund issues and redeems shares. It is calculated in accordance with the standard formula for valuing mutual fund shares. The price used to calculate market returns (“Market Price”) of the Fund generally is determined using the midpoint between the highest bid and the lowest offer on the primary securities exchange on which shares of the Fund are listed for trading, as of the time that the Fund’s NAV is calculated. The Fund’s Market Price may be at, above or below its NAV. The NAV of the Fund will fluctuate with changes in the value of its portfolio holdings. The Market Price of the Fund will fluctuate in accordance with changes in its NAV, as well as market supply and demand.

Premiums or discounts are the differences (expressed as a percentage) between the NAV and Market Price of the Fund on a given day, generally at the time the NAV is calculated. A premium is the amount that the Fund is trading above the reported NAV, expressed as a percentage of the NAV. A discount is the amount that the Fund is trading below the reported NAV, expressed as a percentage of the NAV.

The following information shows the frequency of distributions of premiums and discounts for the Fund for each full calendar quarter of 2010 through September 30, 2011.

Each line in the table shows the number of trading days in which the Fund traded within the premium/discount range indicated. The number of trading days in each premium/discount range is also shown as a percentage of the total number of trading days in the period covered by the table. All data presented here represents past performance, which cannot be used to predict future results.

Premium/Discount Range

Percentage of Total Days
Greater than 0.5% 1 0.23%
Between 0.5% and -0.5% 440 99.77
   441 100.00%

II. Total Return Information

The tables that follow present information about the total returns of the Fund and the Underlying Index as of the fiscal year ended July 31, 2011.

“Average Annual Total Returns” represent the average annual change in value of an investment over the periods indicated. “Cumulative Total Returns” represent the total change in value of an investment over the periods indicated.

The Fund’s NAV is the value of one share of the Fund as calculated in accordance with the standard formula for valuing mutual fund shares. The NAV return is based on the NAV of the Fund and the market return is based on the Market Price of the Fund. Market Price is determined by using the midpoint between the highest bid and the lowest offer on the primary stock exchange on which shares of the Fund are listed for trading, as of the time that the Fund’s NAV is calculated. Since shares of the Fund did not trade in the secondary market until after the Fund’s inception, for the period from inception to the first day of secondary market trading in shares of the Fund, the NAV of the Fund is used as a proxy for the Market Price to calculate market returns. Market and NAV returns assume that dividends and capital gain distributions have been reinvested in the Fund at Market Price and NAV, respectively.

An index is a statistical composite that tracks a specified financial market or sector. Unlike the Fund, the Underlying Index does not actually hold a portfolio of securities and therefore does not incur the expenses incurred by the Fund. These expenses negatively impact the performance of the Fund. Also, market returns do not include brokerage commissions that may be payable on secondary market transactions. If brokerage commissions were included, market returns would be lower. The returns shown in the following tables do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption or sale of Fund shares. The investment return and principal value of shares of the Fund will vary with changes in market conditions. Shares of the Fund may be worth more or less than their original cost when they are redeemed or sold in the market. The Fund’s past performance is no guarantee of future results.

Fund Overview

iSHARES® NYSE COMPOSITE INDEX FUND

Ticker: NYC Stock Exchange: NYSE Arca

Investment Objective

The iShares NYSE Composite Index Fund (the “Fund”) seeks investment results that correspond generally to the price and yield performance, before fees and expenses, of the NYSE Composite Index (the “Underlying Index”).

Fees and Expenses

The following table describes the fees and expenses that you will incur if you own shares of the Fund. The investment advisory agreement between iShares Trust (the “Trust”) and BlackRock Fund Advisors (“BFA”) (the “Investment Advisory Agreement”) provides that BFA will pay all operating expenses of the Fund, except interest expenses, taxes, brokerage expenses, future distribution fees or expenses, and extraordinary expenses.

You may also incur usual and customary brokerage commissions when buying or selling shares of the Fund, which are not reflected in the example that follows:

Example. This Example is intended to help you compare the cost of owning shares of the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

Portfolio Turnover. The Fund may pay transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 5% of the average value of its portfolio.

Principal Investment Strategies

The Underlying Index measures the performance of all common stocks, American Depositary Receipts, real estate investment trusts (“REITs”) and tracking stocks listed on the New York Stock Exchange (“NYSE”). As of September 30, 2011, the Underlying Index had a total market capitalization of approximately $13.97 trillion. To become listed on the NYSE, a company must meet the NYSE’s substantive financial and other listing standards. The securities in the Underlying Index represent a broad spectrum of large-, mid- and small-capitalization companies. Although all of the securities in the Underlying Index are registered for sale in the U.S., as of September 30, 2011, approximately 18.44% of the Underlying Index’s component securities were issued by non-U.S. companies.

BFA uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to “beat” the index it tracks and does not seek temporary defensive positions when markets decline or appear overvalued.

Indexing may eliminate the chance that the Fund will substantially outperform the Underlying Index but also may reduce some of the risks of active management, such as poor security selection. Indexing seeks to achieve lower costs and better after-tax performance by keeping portfolio turnover low in comparison to actively managed investment companies.

BFA uses a representative sampling indexing strategy to manage the Fund. “Representative sampling” is an indexing strategy that involves investing in a representative sample of securities that collectively has an investment profile similar to the Underlying Index. The securities selected are expected to have, in the aggregate, investment characteristics (based on factors such as market capitalization and industry weightings), fundamental characteristics (such as return variability and yield) and liquidity measures similar to those of the Underlying Index. The Fund may or may not hold all of the securities in the Underlying Index.

The Fund generally invests at least 90% of its assets in securities of the Underlying Index and in depositary receipts representing securities of the Underlying Index. The Fund may invest the remainder of its assets in securities not included in the Underlying Index, but which BFA believes will help the Fund track the Underlying Index and in other investments including futures contracts, options on futures contracts, options and swaps as well as cash and cash equivalents, including shares of money market funds advised by BFA or its affiliates.

Table Of Contents



The Fund may lend securities representing up to one-third of the value of the Fund’s total assets (including the value of the collateral received).

The Underlying Index is sponsored by an organization (the “Index Provider”) that is independent of the Fund and BFA. The Index Provider determines the composition and relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index. The Fund’s Index Provider is NYSE Euronext.

Industry Concentration Policy. The Fund will concentrate its investments (i.e., hold 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. For purposes of this limitation, securities of the U.S. government (including its agencies and instrumentalities) and repurchase agreements collateralized by U.S. government securities are not considered to be issued by members of any industry.

Summary of Principal Risks

As with any investment, you could lose all or part of your investment in the Fund, and the Fund’s performance could trail that of other investments. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund’s net asset value per share (“NAV”), trading price, yield, total return and ability to meet its investment objective.

Asset Class Risk. Securities in the Underlying Index or in the Fund’s portfolio may underperform in comparison to the general securities markets or other asset classes.

Concentration Risk. To the extent that the Fund’s investments are concentrated in a particular issuer, region, country, market, industry or asset class, the Fund may be susceptible to loss due to adverse occurrences affecting that issuer, region, country, market, industry or asset class.

Consumer Goods Sector Risk. The consumer goods sector may be affected by changes in social trends and consumer demands. Many consumer goods are sold internationally and such companies are subject to market conditions in other countries and regions.

Equity Securities Risk. Equity securities are subject to changes in value and their values may be more volatile than other asset classes.

Financial Sector Risk. Performance of companies in the financial sector may be adversely impacted by many factors, including, among others, government regulations, economic conditions, credit rating downgrades, changes in interest rates, and decreased liquidity in credit markets. This sector has experienced significant losses in the recent past, and the impact of more stringent capital requirements and of recent or future regulation on any individual financial company or on the sector as a whole cannot be predicted.

Issuer Risk. Fund performance depends on the performance of individual securities to which the Fund has exposure. Changes to the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA’s investment management strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares, losses from trading in secondary markets, periods of high volatility and disruption in the creation/redemption process of the Fund. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV.

Mid-Capitalization Companies Risk. The Fund may invest in the securities of mid-capitalization companies. Compared to large-capitalization companies, mid-capitalization companies may be less stable and more susceptible to adverse developments and their securities may be more volatile and less liquid.

Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers are subject to the risks associated with investing in those non-U.S. markets, such as heightened risks of inflation or nationalization. The Fund may lose money due to political, economic and geographic events affecting a non-U.S. issuer or market.

Oil and Gas Sector Risk. Companies in the oil and gas sector are affected by worldwide energy prices, exploration and production costs. Companies in the oil and gas sector may have significant operations in areas at risk for natural disasters, social unrest and environmental damage. These companies may also be at risk for increased government regulation and intervention, litigation, and negative publicity and perception.

Passive Investment Risk. The Fund is not actively managed and BFA does not attempt to take defensive positions under any market conditions, including declining markets.

Securities Lending Risk. The Fund may engage in securities lending. Securities lending involves the risk that the Fund may lose money because the borrower of the Fund’s loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Small-Capitalization Companies Risk. The Fund may invest in the securities of small-capitalization companies. Compared to mid- and large-capitalization companies, small-capitalization companies may be less stable and more susceptible to adverse developments and their securities may be more volatile and less liquid.

Tracking Error Risk. The performance of the Fund may diverge from that of the Underlying Index. Because the Fund employs a representative sampling strategy, the Fund may experience tracking error to a greater extent than a fund that seeks to replicate an index.

Performance Information

The bar chart and table that follow show how the Fund has performed on a calendar year basis and provide an indication of the risks of investing in the Fund. Both assume that all dividends and distributions have been reinvested in the Fund. Past performance (before and after taxes) does not necessarily indicate how the Fund will perform in the future. Supplemental information about the Fund’s performance is shown under the heading Total Return Information in the Supplemental Information section of the Fund’s prospectus (the “Prospectus”).

Year by Year Returns1 (Years Ended December 31)


1 The Fund’s total return for the nine months ended September 30, 2011 was -13.14%.

The best calendar quarter return during the periods shown above was 19.52% in the 2nd quarter of 2009; the worst was
-22.90% in the 4th quarter of 2008.

1 After-tax returns in the table above are calculated using the historical highest individual U.S. federal marginal income tax rates and do not reflect the impact of state or local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown, and after-tax returns shown are not relevant to tax-exempt investors or investors who hold shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts (“IRAs”). Fund returns after taxes on distributions and sale of Fund shares are calculated assuming that an investor has sufficient capital gains of the same character from other investments to offset any capital losses from the sale of Fund shares. As a result, Fund returns after taxes on distributions and sale of Fund shares may exceed Fund returns before taxes and/or returns after taxes on distributions.

Management

Investment Adviser. BlackRock Fund Advisors.

Portfolio Managers. Rene Casis, Diane Hsiung and Greg Savage (the “Portfolio Managers”) are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager supervises a portfolio management team. Mr. Casis, Ms. Hsiung and Mr. Savage have been Portfolio Managers of the Fund since 2010, 2008 and 2008, respectively.

Purchase and Sale of Fund Shares

The Fund is an exchange-traded fund (commonly referred to as an “ETF”). Individual Fund shares may only be purchased and sold on a national securities exchange through a broker-dealer. The price of Fund shares is based on market price, and because ETF shares trade at market prices rather than NAV, shares may trade at a price greater than NAV (a premium) or less than NAV (a discount). The Fund will only issue or redeem shares that have been aggregated into blocks of 50,000 shares or multiples thereof (“Creation Units”) to authorized participants who have entered into agreements with the Fund’s distributor. The Fund generally will issue or redeem Creation Units in return for a designated portfolio of securities (and an amount of cash) that the Fund specifies each day.

Tax Information

The Fund intends to make distributions that may be taxable to you as ordinary income or capital gains, unless you are investing through a tax-deferred arrangement such as a 401(k) plan or an IRA.

Payments to Broker-Dealers and other Financial Intermediaries

If you purchase shares of the Fund through a broker-dealer or other financial intermediary (such as a bank), BFA or other related companies may pay the intermediary for marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems or other services related to the sale or promotion of the Fund. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.

More Information About the Fund

This Prospectus contains important information about investing in the Fund. Please read this Prospectus carefully before you make any investment decisions. Additional information regarding the Fund is available at www.iShares.com.

BFA is the investment adviser to the Fund. Shares of the Fund are listed for trading on NYSE Arca, Inc. (“NYSE Arca”). The market price for a share of the Fund may be different from the Fund’s most recent NAV.

ETFs are funds that trade like other publicly-traded securities. The Fund is designed to track an index. Similar to shares of an index mutual fund, each share of the Fund represents a partial ownership in an underlying portfolio of securities intended to track a market index. Unlike shares of a mutual fund, which can be bought and redeemed from the issuing fund by all shareholders at a price based on NAV, shares of the Fund may be purchased or redeemed directly from the Fund at NAV solely by authorized participants. Also unlike shares of a mutual fund, shares of the Fund are listed on a national securities exchange and trade in the secondary market at market prices that change throughout the day.

The Fund invests in a particular segment of the securities markets and seeks to track the performance of a securities index that generally is not representative of the market as a whole. The Fund is designed to be used as part of broader asset allocation strategies. Accordingly, an investment in the Fund should not constitute a complete investment program.

An index is a theoretical financial calculation while the Fund is an actual investment portfolio. The performance of the Fund and the Underlying Index may vary due to transaction costs, non-U.S. currency valuations, asset valuations, corporate actions (such as mergers and spin-offs), timing variances and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions (such as diversification requirements) that apply to the Fund but not to the Underlying Index or to the use of representative sampling. “Tracking error” is the difference between the performance (return) of the Fund’s portfolio and that of the Underlying Index. BFA expects that, over time, the Fund’s tracking error will not exceed 5%. Because the Fund uses a representative sampling indexing strategy, it can be expected to have a larger tracking error than if it used a replication indexing strategy. “Replication” is an indexing strategy in which a fund invests in substantially all of the securities in its underlying index in approximately the same proportions as in the underlying index.

An investment in the Fund is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, BFA or any of its affiliates.

The Fund’s investment objective and the Underlying Index may be changed without shareholder approval.

A Further Discussion of Principal Risks

The Fund is subject to various risks, including the principal risks noted below, any of which may adversely affect the Fund’s NAV, trading price, yield, total return and ability to meet its investment objective. You could lose all or part of your investment in the Fund, and the Fund could underperform other investments.

Asset Class Risk. The securities in the Underlying Index or in the Fund’s portfolio may underperform the returns of other securities or indexes that track other industries, groups of industries, markets, asset classes or sectors. Various types of securities or indexes tend to experience cycles of outperformance and underperformance in comparison to the general securities markets.

Concentration Risk. To the extent that the Fund’s portfolio reflects the Underlying Index’s concentration in the securities of a particular issuer or issuers in a particular country, group of countries, region, market, industry, group of industries, sector or asset class, the Fund may be adversely affected by the performance of those securities, may be subject to increased price volatility and may be more susceptible to adverse economic, market, political or regulatory occurrences affecting that issuer, country, group of countries, region, market, industry, group of industries, sector or asset class.

Consumer Goods Sector Risk. The consumer goods sector may be strongly affected by social trends, marketing campaigns and other factors affecting consumer demand. Governmental regulation affecting the use of various food additives may affect the profitability of certain companies represented in the Underlying Index. In addition, tobacco companies may be adversely affected by new laws, regulations and litigation. Many consumer goods in the United States may also be marketed globally, and such consumer goods companies may be affected by the demand and market conditions in non-U.S. countries.

Equity Securities Risk. The Fund invests in equity securities, which are subject to changes in value that may be attributable to market perception of a particular issuer or to general stock market fluctuations that affect all issuers. Investments in equity securities may be more volatile than investments in other asset classes.

Financial Sector Risk. Companies in the financial sector of an economy are often subject to governmental regulation and, recently, government intervention and the potential for additional regulation, which may adversely affect the scope of their activities, the prices they can charge and the amount of capital they must maintain. Governmental regulation may change frequently and may have significant adverse consequences for companies in the financial sector, including effects not intended by such regulation. The impact of recent or future regulation in various countries on any individual financial company or on the sector as a whole cannot be predicted. Certain risks may impact the value of investments in the financial sector more severely than investments outside this sector, including the risks associated with companies that operate with substantial financial leverage. Companies in the financial sector may also be adversely affected by increases in interest rates and loan losses, decreases in the availability of money or asset valuations, credit rating downgrades and adverse conditions in other related markets. Over the past few years, the deterioration of the

credit markets has impacted a broad range of mortgage, asset-backed, auction rate, sovereign debt and other markets, including U.S. and non-U.S. credit and interbank money markets, thereby affecting a wide range of financial institutions and markets. This situation has created instability in the financial markets and caused certain financial companies to incur large losses. Some financial companies have experienced declines in the valuations of their assets, taken actions to raise capital (such as the issuance of debt or equity securities), or even ceased operations. Some financial companies have borrowed significant amounts of capital from governments and may face future government-imposed restrictions on their businesses or increased government intervention. These actions have caused the securities of many financial companies to decline in value. Insurance companies, in particular, may be subject to severe price competition, which may have an adverse impact on their profitability.

Issuer Risk. The performance of the Fund depends on the performance of individual securities to which the Fund has exposure. Any issuer of these securities may perform poorly, causing the value of its securities to decline. Poor performance may be caused by poor management decisions, competitive pressures, changes in technology, expiration of patent protection, disruptions in supply, labor problems or shortages, corporate restructurings, fraudulent disclosures or other factors. Issuers may, in times of distress or at their own discretion, decide to reduce or eliminate dividends, which may also cause their stock prices to decline.

Management Risk. The Fund may not fully replicate the Underlying Index and may hold securities not included in the Underlying Index. As a result, the Fund is subject to the risk that BFA’s investment management strategy, the implementation of which is subject to a number of constraints, may not produce the intended results.

Market Risk. The Fund could lose money due to short-term market movements and over longer periods during market downturns. Securities may decline in value due to factors affecting securities markets generally or particular industries represented in the markets. The value of a security may decline due to general market conditions, economic trends or events that are not specifically related to the issuer of the security or to factors that affect a particular industry or industries. During a general downturn in the securities markets, multiple asset classes may be negatively affected.

Market Trading Risk

Absence of Active Market. Although shares of the Fund are listed for trading on one or more stock exchanges, there can be no assurance that an active trading market for such shares will develop or be maintained.

Risk of Secondary Listings. The Fund’s shares may be listed or traded on U.S. and non-U.S. stock exchanges other than the U.S. stock exchange where the Fund’s primary listing is maintained. There can be no assurance that the Fund’s shares will continue to trade on any such stock exchange or in any market or that the Fund’s shares will continue to meet the requirements for listing or trading on any exchange or in any market. The Fund’s shares may be less actively traded in certain markets than others, and investors are subject to the execution and settlement risks and market standards of the market where they or their broker direct their trades for execution. Certain information available to investors who trade Fund shares on a U.S. stock exchange

during regular U.S. market hours may not be available to investors who trade in other markets, which may result in secondary market prices in such markets being less efficient.

Secondary Market Trading Risk. Shares of the Fund may trade in the secondary market at times when the Fund does not accept orders to purchase or redeem shares. At such times, shares may trade in the secondary market with more significant premiums or discounts than might be experienced at times when the Fund accepts purchase and redemption orders.

Secondary market trading in Fund shares may be halted by a stock exchange because of market conditions or other reasons. In addition, trading in Fund shares on a stock exchange or in any market may be subject to trading halts caused by extraordinary market volatility pursuant to “circuit breaker” rules on the stock exchange or market. There can be no assurance that the requirements necessary to maintain the listing or trading of Fund shares will continue to be met or will remain unchanged.

Shares of the Fund May Trade at Prices Other Than NAV. Shares of the Fund trade on stock exchanges at prices at, above or below their most recent NAV. The NAV of the Fund is calculated at the end of each business day and fluctuates with changes in the market value of the Fund’s holdings since the most recent calculation. The trading prices of the Fund’s shares fluctuate continuously throughout trading hours based on market supply and demand rather than NAV. The trading prices of the Fund’s shares may deviate significantly from NAV during periods of market volatility. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV. However, because shares can be created and redeemed in Creation Units at NAV (unlike shares of many closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their NAVs), BFA believes that large discounts or premiums to the NAV of the Fund are not likely to be sustained over the long-term. While the creation/redemption feature is designed to make it likely that the Fund’s shares normally will trade on stock exchanges at prices close to the Fund’s next calculated NAV, exchange prices are not expected to correlate exactly with the Fund’s NAV due to timing reasons as well as market supply and demand factors. In addition, disruptions to creations and redemptions or extreme market volatility may result in trading prices for shares of the Fund that differ significantly from its NAV.

Costs of Buying or Selling Fund Shares. Buying or selling Fund shares on an exchange involves two types of costs that apply to all securities transactions. When buying or selling shares of the Fund through a broker, you will likely incur a brokerage commission or other charges imposed by brokers as determined by that broker. In addition, you may incur the cost of the “spread” – that is, the difference between what investors are willing to pay for Fund shares (the “bid” price) and the price at which they are willing to sell Fund shares (the “ask” price). Because of the costs inherent in buying or selling Fund shares, frequent trading may detract significantly from investment results and an investment in Fund shares may not be advisable for investors who anticipate regularly making small investments.

Mid-Capitalization Companies Risk. Many of the companies in which the Fund invests are considered mid-capitalization companies. Stock prices of mid-capitalization

companies may be more volatile than those of large-capitalization companies and, therefore, the Fund’s share price may be more volatile than those of funds that invest a larger percentage of their assets in stocks issued by large-capitalization companies. Stock prices of mid-capitalization companies are also more vulnerable than those of large-capitalization companies to adverse business or economic developments, and the stocks of mid-capitalization companies may be less liquid, making it difficult for the Fund to buy and sell them. In addition, mid-capitalization companies generally have less diverse product lines than large-capitalization companies and are more susceptible to adverse developments related to their products.

Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers are subject to all of the risks of investing in the markets where such issuers are located, including heightened risks of inflation or nationalization and market fluctuations caused by economic and political developments. As a result of investing in non-U.S. securities, the Fund may be subject to increased risk of loss caused by any of the factors listed below:

  • Lower levels of liquidity and market efficiency;
  • Greater securities price volatility;
  • Exchange rate fluctuations and exchange controls;
  • Less availability of public information about issuers;
  • Limitations on foreign ownership of securities;
  • Imposition of withholding or other taxes;
  • Imposition of restrictions on the expatriation of the funds or other assets of the Fund;
  • Higher transaction and custody costs and delays in settlement procedures;
  • Difficulties in enforcing contractual obligations;
  • Lower levels of regulation of the securities market;
  • Weaker accounting, disclosure and reporting requirements; and
  • Legal principles related to corporate governance, directors’ fiduciary duties and liabilities and stockholders’ rights in markets in which the Fund invests may differ and/or may not be as extensive or protective as those that apply in the United States.

Oil and Gas Sector Risk. The profitability of companies in the oil and gas sector is related to worldwide energy prices, exploration, and production spending. Companies in the oil and gas sector may be adversely affected by natural disasters or other catastrophes. Companies in the oil and gas sector may be at risk for environmental damage claims and other types of litigation. Companies in the oil and gas sector may be adversely affected by changes in exchange rates, interest rates, changes in prices for competitive energy services, economic conditions, tax treatment, government regulation and intervention, negative perception and world events in the regions where companies operate (e.g., expropriation, nationalization, confiscation of assets and property or imposition of restrictions on foreign investments and repatriation of capital, military coups, social unrest, violence or labor unrest). Companies in the oil

and gas sector may have significant capital investments in, or engage in transactions involving, emerging market countries, which may heighten these risks.

Passive Investment Risk. The Fund is not actively managed and may be affected by a general decline in market segments related to the Underlying Index. The Fund invests in securities included in, or representative of, the Underlying Index regardless of their investment merits. BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

Securities Lending Risk. The Fund may engage in securities lending. Securities lending involves the risk that the Fund may lose money because the borrower of the Fund’s loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for the loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Small-Capitalization Companies Risk. Many of the companies in which the Fund invests are considered small-capitalization companies. Stock prices of small-capitalization companies may be more volatile than those of larger companies and, therefore, the Fund’s share price may be more volatile than those of funds that invest a larger percentage of their assets in stocks issued by mid- or large-capitalization companies. Stock prices of small-capitalization companies are generally more vulnerable than those of mid- or large-capitalization companies to adverse business and economic developments. Securities of small-capitalization companies may be thinly traded, making it difficult for the Fund to buy and sell them. In addition, small-capitalization companies are typically less financially stable than larger, more established companies and may depend on a small number of essential personnel, making them more vulnerable to loss of personnel. Small-capitalization companies also normally have less diverse product lines than mid- or large-capitalization companies and are more susceptible to adverse developments concerning their products.

Tracking Error Risk. Imperfect correlation between the Fund’s portfolio securities and those in the Underlying Index, rounding of prices, changes to the Underlying Index and regulatory requirements may cause tracking error, which is the divergence of the Fund’s performance from that of the Underlying Index. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Underlying Index does not. Because the Fund employs a representative sampling strategy, the Fund may experience tracking error to a greater extent than a fund that seeks to replicate an index.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

Asian Economic Risk. Certain Asian economies have experienced over-extension of credit, currency devaluations and restrictions, high unemployment, high inflation, decreased exports and economic recessions. Economic events in any one Asian

country may have a significant economic effect on the entire Asian region, as well as on major trading partners outside Asia, and any adverse event in the Asian markets may have a significant adverse effect on other Asian economies.

Basic Materials Sector Risk. Issuers in the basic materials sector could be adversely affected by commodity price volatility, exchange rates, import controls and increased competition. Production of industrial materials often exceeds demand as a result of over-building or economic downturns, leading to poor investment returns. Issuers in the basic materials sector are at risk for environmental damage and product liability claims and may be adversely affected by depletion of resources, delays in technical progress, labor relations and government regulations.

Consumer Services Sector Risk. The success of consumer product manufacturers and retailers (including food and drug retailers, general retailers, media, and travel and leisure) is tied closely to the performance of the domestic and international economy, interest rates, exchange rates, competition and consumer confidence. The consumer services sector depends heavily on disposable household income and consumer spending. Companies in the consumer services sector may be subject to severe competition, which may also have an adverse impact on their profitability. Changes in demographics and consumer preferences may affect the success of consumer products.

European Economic Risk. The Economic and Monetary Union (the “EMU”) of the European Union (the “EU”) requires member countries to comply with restrictions on inflation rates, deficits, interest rates, debt levels and fiscal and monetary controls, each of which may significantly affect every country in Europe. Decreasing imports or exports, changes in governmental or EU regulations on trade, changes in the exchange rate of the euro, the default or threat of default by an EU member country on its sovereign debt, and/or an economic recession in an EU member country may have a significant adverse effect on the economies of EU member countries and on major trading partners outside Europe. The European financial markets have recently experienced volatility and have been adversely affected by concerns about economic downturns, credit rating downgrades, rising government debt levels and possible default on or restructuring of government debt in several European countries, including Greece, Ireland, Italy, Portugal and Spain. A default or debt restructuring by any European country would adversely impact holders of that country’s debt, and sellers of credit default swaps linked to that country’s creditworthiness, which may be located in countries other than those listed in the previous sentence. These events have adversely affected the value and exchange rate of the euro and may continue to significantly affect the economies of every country in Europe, including EU member countries that do not use the euro and non-EU member countries.

Health Care Sector Risk. The profitability of companies in the health care sector may be affected by extensive government regulations, restrictions on government reimbursement for medical expenses, rising costs of medical products and services, pricing pressure, an increased emphasis on outpatient services, limited number of products, industry innovation, changes in technologies and other market developments. Many health care companies are heavily dependent on patent protection. The expiration of patents may adversely affect the profitability of these

companies. Many health care companies are subject to extensive litigation based on product liability and similar claims. Health care companies are subject to competitive forces that may make it difficult to raise prices and, in fact, may result in price discounting. Many new products in the health care sector may be subject to regulatory approvals. The process of obtaining such approvals may be long and costly. Companies in the health care sector may be thinly capitalized and may be susceptible to product obsolescence.

Industrials Sector Risk. The stock prices of companies in the industrials sector are affected by supply and demand, both for their specific product or service and for industrials sector products in general. The products of manufacturing companies may face obsolescence due to rapid technological developments and frequent new product introduction. Government regulations, world events, economic conditions and exchange rates affect the performance of companies in the industrials sector. Companies in the industrials sector may be adversely affected by liability for environmental damage and product liability claims.

North American Economic Risk. The United States is Canada’s and Mexico’s largest trading and investment partner. The Canadian and Mexican economies are significantly affected by developments in the U.S. economy. Since the implementation of the North American Free Trade Agreement (“NAFTA”) in 1994 among Canada, the United States and Mexico, total merchandise trade between the three countries have increased. To further this relationship, the three NAFTA countries entered into the Security and Prosperity Partnership of North America in March 2005, which may further affect Canada’s and Mexico’s dependency on the U.S. economy. Economic events in any one North American country can have a significant economic effect on the entire North American region, and on some or all of the North American countries in which the Fund invests.

Technology Sector Risk. The Fund invests in technology companies, which face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Technology companies may have limited product lines, markets, financial resources or personnel. The products of technology companies may face obsolescence due to rapid technological developments and frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Companies in the technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies.

Telecommunications Sector Risk. The telecommunications sector is subject to extensive government regulation. The costs of complying with governmental regulations, delays or failure to receive required regulatory approvals, or the enactment of new adverse regulatory requirements may negatively affect the business of the telecommunications companies. Government actions around the world, specifically in the area of pre-marketing clearance of products and prices, can be arbitrary and unpredictable. Companies in the telecommunications sector may encounter distressed cash flows due to the need to commit substantial capital to meet increasing competition, particularly in formulating new products and services using

new technology. Technological innovations may make the products and services of telecommunications companies obsolete.

Portfolio Holdings Information

A description of the Trust’s policies and procedures with respect to the disclosure of the Fund’s portfolio securities is available in the Fund’s Statement of Additional Information (“SAI”). The top holdings of the Fund can be found at www.iShares.com. Fund fact sheets provide information regarding the Fund’s top holdings and may be requested by calling 1-800-iShares (1-800-474-2737).

Management

Investment Adviser. As investment adviser, BFA has overall responsibility for the general management and administration of the Trust. BFA provides an investment program for the Fund and manages the investment of the Fund’s assets. In managing the Fund, BFA may draw upon the research and expertise of its asset management affiliates with respect to certain portfolio securities. In seeking to achieve the Fund’s investment objective, BFA uses teams of portfolio managers, investment strategists and other investment specialists. This team approach brings together many disciplines and leverages BFA’s extensive resources.

Pursuant to the Investment Advisory Agreement between BFA and the Trust (entered into on behalf of the Fund), BFA is responsible for substantially all expenses of the Fund, except interest expenses, taxes, brokerage expenses, future distribution fees or expenses and extraordinary expenses.

For its investment advisory services to the Fund, BFA is entitled to receive a management fee from the Fund based on a percentage of the Fund’s average daily net assets, at the annual rate of 0.25%.

BFA is located at 400 Howard Street, San Francisco, CA 94105. It is a wholly owned subsidiary of BTC, which in turn is indirectly wholly-owned by BlackRock, Inc. (“BlackRock”). As of September 30, 2011, BTC and its affiliates, including BFA and BlackRock, provided investment advisory services for assets in excess of $3.35 trillion. BFA, BTC, BlackRock Execution Services, BlackRock and their affiliates deal, trade and invest for their own accounts in the types of securities in which the Fund may also invest.

A discussion regarding the basis for the Trust’s Board of Trustees’ (the “Board”) approval of the Investment Advisory Agreement with BFA is available in the Fund’s annual report for the period ended July 31.

Portfolio Managers. Rene Casis, Diane Hsiung and Greg Savage are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager is responsible for various functions related to portfolio management, including, but not limited to, investing cash inflows, coordinating with members of his or her portfolio management team to focus on certain asset classes, implementing investment strategy, researching and reviewing investment strategy and overseeing members of his or her portfolio management team that have more limited responsibilities.

Rene Casis has been employed by BFA (formerly, Barclays Global Fund Advisors (“BGFA”)) and BTC (formerly, Barclays Global Investors, N.A. (“BGI”)) as a senior portfolio manager since 2009. From 2005 to 2009, Mr. Casis was a trader at Barclays Capital. Prior to that, Mr. Casis was a portfolio manager from 2000 to 2005 for BGFA and BGI. Mr. Casis has been a Portfolio Manager of the Fund since 2010.

Diane Hsiung has been employed by BFA and BTC as a senior portfolio manager since 2007. Prior to that, Ms. Hsiung was a portfolio manager from 2002 to 2006 for BGFA and BGI. Ms. Hsiung has been a Portfolio Manager of the Fund since 2008.

Greg Savage has been employed by BFA and BTC as a senior portfolio manager since 2006. Prior to that, Mr. Savage was a portfolio manager from 2001 to 2006 for BGFA and BGI. Mr. Savage has been a Portfolio Manager of the Fund since 2008.

The Fund’s SAI provides additional information about the Portfolio Managers’ compensation, other accounts managed by the Portfolio Managers and the Portfolio Managers’ ownership (if any) of shares in the Fund.

Administrator, Custodian and Transfer Agent. State Street Bank and Trust Company (“State Street”) is the administrator, custodian and transfer agent for the Fund.

Conflicts of Interest. BFA wants you to know that there are certain entities with which BFA has relationships that may give rise to conflicts of interest, or the appearance of conflicts of interest. These entities include the following: BFA’s affiliates (including BlackRock and The PNC Financial Services Group, Inc., and each of their affiliates, directors, partners, trustees, managing members, officers and employees (collectively, the “Affiliates”)) and BlackRock’s significant shareholder, Barclays Bank PLC and its affiliates, including Barclays PLC (each, an “Entity” and together, the “Entities”).

The activities of BFA, the Affiliates and the Entities in the management of, or their interest in, their own accounts and other accounts they manage, may present conflicts of interest that could disadvantage the Fund and its shareholders. BFA and its Affiliates or the Entities provide investment management services to other funds and discretionary managed accounts that may follow an investment program similar to that of the Fund. BFA, its Affiliates and the Entities are involved worldwide with a broad spectrum of financial services and asset management activities and may engage in the ordinary course of business in activities in which their interests or the interests of their clients may conflict with those of the Fund. BFA, one or more of the Affiliates or the Entities acts, or may act, as an investor, investment banker, research provider, investment manager, financier, underwriter, advisor, market maker, trader, prime broker, lender, agent or principal, and have other direct and indirect interests, in securities, currencies and other instruments in which the Fund may directly or indirectly invest. Thus, it is likely that the Fund will have multiple business relationships with and will invest in, engage in transactions with, make voting decisions with respect to, or obtain services from, entities for which BFA, an Affiliate or an Entity performs or seeks to perform investment banking or other services.

BFA or one or more Affiliates or Entities may engage in proprietary trading and advise accounts and funds that have investment objectives similar to those of the Fund and/

or that engage in and compete for transactions in the same types of securities, currencies and other instruments as the Fund, including in securities issued by other open-end and closed-end investment management companies, including investment companies that are affiliated with the Fund and BFA, to the extent permitted under the Investment Company Act of 1940, as amended (the “1940 Act”). The trading activities of BFA, these Affiliates and Entities are carried out without reference to positions held directly or indirectly by the Fund and may result in BFA, an Affiliate or an Entity having positions that are adverse to those of the Fund.

No Affiliate or Entity is under any obligation to share any investment opportunity, idea or strategy with the Fund. As a result, an Affiliate or an Entity may compete with the Fund for appropriate investment opportunities. As a result of this and several other factors, the results of the Fund’s investment activities may differ from those of an Affiliate or an Entity and of other accounts managed by an Affiliate or an Entity, and it is possible that the Fund could sustain losses during periods in which one or more Affiliates or Entities and other accounts achieve profits on their trading for proprietary or other accounts. The opposite result is also possible.

The Fund may, from time to time, enter into transactions in which BFA or an Affiliate’s or an Entity’s clients have an interest adverse to the Fund. Furthermore, transactions undertaken by Affiliate-advised clients may adversely impact the Fund. Transactions by one or more Affiliate- or Entity-advised clients or BFA may have the effect of diluting or otherwise disadvantaging the values, prices or investment strategies of the Fund.

An Entity may maintain securities indices as part of its product offerings. Index-based funds seek to track the performance of securities indices and may use the name of the index in the fund name. Index providers, including the Entities, may be paid licensing fees for use of their indices or index names. Entities will not be obligated to license their indices to BFA and its Affiliates, and BFA and its Affiliates will not be assured that the terms of any index licensing agreement with the Entities will be as favorable as those terms offered to other index licensees.

The Fund’s activities may be limited because of regulatory restrictions applicable to one or more Affiliates or Entities, and/or their internal policies designed to comply with such restrictions. In addition, the Fund may invest in securities of companies with which an Affiliate or an Entity has or is trying to develop investment banking relationships or in which an Affiliate or an Entity has significant debt or equity investments. The Fund also may invest in securities of companies for which an Affiliate or an Entity provides or may some day provide research coverage. An Affiliate or an Entity may have business relationships with and purchase or distribute or sell services or products from or to distributors, consultants or others who recommend the Fund or who engage in transactions with or for the Fund, and may receive compensation for such services. The Fund may also make brokerage and other payments to Affiliates or Entities in connection with the Fund’s portfolio investment transactions.

Pursuant to a securities lending program approved by the Board, the Fund has retained an Affiliate of BFA to serve as the securities lending agent for the Fund to the extent that the Fund participates in the securities lending program. For these services, the lending agent may receive a fee from the Fund, including a fee based on the returns earned on the Fund’s investment of the cash received as collateral for any loaned

securities. In addition, one or more Affiliates may be among the entities to which the Fund may lend its portfolio securities under the securities lending program.

The activities of BFA, the Affiliates or Entities may give rise to other conflicts of interest that could disadvantage the Fund and its shareholders. BFA has adopted policies and procedures designed to address these potential conflicts of interest. See the Fund’s SAI for further information.

Shareholder Information

Additional shareholder information, including how to buy and sell shares of the Fund, is available free of charge by calling toll-free: 1-800-iShares (1-800-474-2737) or visiting our website at www.iShares.com.

Buying and Selling Shares. Shares of the Fund may be acquired or redeemed directly from the Fund only in Creation Units or multiples thereof, as discussed in the Creations and Redemptions section of this Prospectus. Only an Authorized Participant (as defined in the Creations and Redemptions section) may engage in creation or redemption transactions directly with the Fund. Once created, shares of the Fund generally trade in the secondary market in amounts less than a Creation Unit.

Shares of the Fund are listed on a national securities exchange for trading during the trading day. Shares can be bought and sold throughout the trading day like shares of other publicly-traded companies. The Trust does not impose any minimum investment for shares of the Fund purchased on an exchange. The Fund’s shares trade under the trading symbol “NYC.”

Buying or selling Fund shares on an exchange involves two types of costs that may apply to all securities transactions. When buying or selling shares of the Fund through a broker, you will likely incur a brokerage commission or other charges determined by your broker. The commission is frequently a fixed amount and may be a significant proportional cost for investors seeking to buy or sell small amounts of shares. In addition, you may incur the cost of the “spread” – that is, any difference between the bid price and the ask price. The spread varies over time for shares of the Fund based on its trading volume and market liquidity, and is generally lower if the Fund has a lot of trading volume and market liquidity, and higher if the Fund has little trading volume and market liquidity.

The Board has adopted a policy of not monitoring for frequent purchases and redemptions of Fund shares (“frequent trading”) that appear to attempt to take advantage of a potential arbitrage opportunity presented by a lag between a change in the value of the Fund’s portfolio securities after the close of the primary markets for the Fund’s portfolio securities and the reflection of that change in the Fund’s NAV (“market timing”), because the Fund generally sells and redeems its shares directly through transactions that are in-kind and/or for cash, subject to the conditions described below under Creations and Redemptions. The Board has not adopted a policy of monitoring for other frequent trading activity because shares of the Fund are listed for trading on a national securities exchange.

The national securities exchange on which the Fund’s shares are listed is open for trading Monday through Friday and is closed on weekends and the following holidays:

New Year’s Day, Martin Luther King, Jr. Day, Presidents’ Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day. The Fund’s primary listing exchange is NYSE Arca.

Section 12(d)(1) of the 1940 Act restricts investments by investment companies in the securities of other investment companies. Registered investment companies are permitted to invest in the Fund beyond the limits set forth in Section 12(d)(1), subject to certain terms and conditions set forth in SEC rules or in an SEC exemptive order issued to the Trust. In order for a registered investment company to invest in shares of the Fund beyond the limitations of Section 12(d)(1) pursuant to the exemptive relief obtained by the Trust, the registered investment company must enter into an agreement with the Trust.

Book Entry. Shares of the Fund are held in book-entry form, which means that no stock certificates are issued. The Depository Trust Company (“DTC”) or its nominee is the record owner of all outstanding shares of the Fund and is recognized as the owner of all shares for all purposes.

Investors owning shares of the Fund are beneficial owners as shown on the records of DTC or its participants. DTC serves as the securities depository for shares of the Fund. DTC participants include securities brokers and dealers, banks, trust companies, clearing corporations and other institutions that directly or indirectly maintain a custodial relationship with DTC. As a beneficial owner of shares, you are not entitled to receive physical delivery of stock certificates or to have shares registered in your name, and you are not considered a registered owner of shares. Therefore, to exercise any right as an owner of shares, you must rely upon the procedures of DTC and its participants. These procedures are the same as those that apply to any other securities that you hold in book-entry or “street name” form.

Share Prices. The trading prices of the Fund’s shares in the secondary market generally differ from the Fund’s daily NAV and are affected by market forces such as supply and demand, economic conditions and other factors. Information regarding the intraday value of shares of the Fund, also known as the “indicative optimized portfolio value” (“IOPV”), is disseminated every 15 seconds throughout the trading day by the national securities exchange on which the Fund’s shares are listed or by market data vendors or other information providers. The IOPV is based on the current market value of the securities and/or cash required to be deposited in exchange for a Creation Unit. The IOPV does not necessarily reflect the precise composition of the current portfolio of securities held by the Fund at a particular point in time or the best possible valuation of the current portfolio. Therefore, the IOPV should not be viewed as a “real-time” update of the Fund’s NAV, which is computed only once a day. The IOPV is generally determined by using both current market quotations and/or price quotations obtained from broker-dealers that may trade in the portfolio securities held by the Fund. The quotations of certain Fund holdings may not be updated during U.S. trading hours if such holdings do not trade in the United States. The Fund is not involved in, or responsible for, the calculation or dissemination of the IOPV and makes no representation or warranty as to its accuracy.

Determination of Net Asset Value. The NAV of the Fund normally is determined once daily Monday through Friday, generally as of the regularly scheduled close of

business of the NYSE (normally 4:00 p.m., Eastern time) on each day that the NYSE is open for trading, based on prices at the time of closing provided that (a) any Fund assets or liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers (as detailed below) and (b) U.S. fixed income assets may be valued as of the announced closing time for trading in fixed income instruments in a particular market or exchange. The NAV of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets held by the Fund, and its liabilities, are determined pursuant to valuation policies and procedures approved by the Board. The Fund’s assets and liabilities are valued primarily on the basis of market quotations.

Equity investments are valued at market value, which is generally determined using the last reported official closing price or last trading price on the exchange or market on which the security is primarily traded at the time of valuation.

Generally, trading in foreign securities, U.S. government securities, money market instruments and certain fixed-income securities is substantially completed each day at various times prior to the close of business on the NYSE. The values of such securities used in computing the NAV of the Fund are determined as of such times.

When market quotations are not readily available or are believed by BFA to be unreliable, the Fund’s investments are valued at fair value. Fair value determinations are made by BFA in accordance with policies and procedures approved by the Fund’s Board. BFA may conclude that a market quotation is not readily available or is unreliable if a security or other asset or liability does not have a price source due to its lack of liquidity, if a market quotation differs significantly from recent price quotations or otherwise no longer appears to reflect fair value, where the security or other asset or liability is thinly traded, or where there is a significant event subsequent to the most recent market quotation. A “significant event” is an event that, in the judgment of BFA, is likely to cause a material change to the closing market price of the asset or liability held by the Fund. Foreign securities whose values are affected by volatility that occurs in U.S. markets on a trading day after the close of foreign securities markets may be fair valued.

Fair value represents a good faith approximation of the value of an asset or liability. The fair value of an asset or liability held by the Fund is the amount the Fund might reasonably expect to receive from the current sale of that asset or the cost to extinguish that liability in an arm’s-length transaction. Valuing the Fund’s investments using fair value pricing will result in prices that may differ from current market valuations and that may not be the price at which those investments could have been sold during the period in which the particular fair values were used. Use of fair value prices and certain current market valuations could result in a difference between the prices used to calculate the Fund’s NAV and the prices used by the Underlying Index, which, in turn, could result in a difference between the Fund’s performance and the performance of the Underlying Index.

Dividends and Distributions

General Policies. Dividends from net investment income, if any, generally are declared and paid quarterly by the Fund. Distributions of net realized securities gains, if any, generally are declared and paid once a year, but the Trust may make distributions on a more frequent basis for the Fund. The Trust reserves the right to declare special distributions if, in its reasonable discretion, such action is necessary or advisable to preserve its status as a regulated investment company (“RIC”) or to avoid imposition of income or excise taxes on undistributed income or realized gains.

Dividends and other distributions on shares of the Fund are distributed on a pro rata basis to beneficial owners of such shares. Dividend payments are made through DTC participants and indirect participants to beneficial owners then of record with proceeds received from the Fund.

Dividend Reinvestment Service. No dividend reinvestment service is provided by the Trust. Broker-dealers may make available the DTC book-entry Dividend Reinvestment Service for use by beneficial owners of the Fund for reinvestment of their dividend distributions. Beneficial owners should contact their broker to determine the availability and costs of the service and the details of participation therein. Brokers may require beneficial owners to adhere to specific procedures and timetables. If this service is available and used, dividend distributions of both income and realized gains will be automatically reinvested in additional whole shares of the Fund purchased in the secondary market.

Taxes. As with any investment, you should consider how your investment in shares of the Fund will be taxed. The tax information in this Prospectus is provided as general information, based on current law. You should consult your own tax professional about the tax consequences of an investment in shares of the Fund.

Unless your investment in Fund shares is made through a tax-exempt entity or tax-deferred retirement account, such as an IRA, you need to be aware of the possible tax consequences when the Fund makes distributions or you sell Fund shares.

Taxes on Distributions. Distributions from the Fund’s net investment income (other than qualified dividend income), including distributions of income from securities lending and distributions out of the Fund’s net short-term capital gains, if any, are taxable to you as ordinary income. Distributions by the Fund of net long-term capital gains in excess of net short-term capital losses (capital gain dividends) are taxable to you as long-term capital gains, generally at a 15% tax rate (0% at certain income levels), regardless of how long you have held the Fund’s shares. Distributions by the Fund that qualify as qualified dividend income are taxable to you at long-term capital gain rates for taxable years beginning on or before December 31, 2012. The 15% and 0% tax rates expire for taxable years beginning after December 31, 2012. Maximum long-term capital gain income tax rates are scheduled to rise to 20% in 2013. Beginning in 2013, a 3.8% U.S. federal Medicare contribution tax will be imposed on “net investment income,” including interest, dividends, and capital gains, of U.S. individuals with income exceeding $200,000 (or $250,000 if married and filing jointly), and of estates and trusts.

Dividends will be qualified dividend income to you if they are attributable to qualified dividend income received by the Fund. Generally, qualified dividend income includes dividend income from taxable U.S. corporations and qualified non-U.S. corporations, provided that the Fund satisfies certain holding period requirements in respect of the stock of such corporations and has not hedged its position in the stock in certain ways. Substitute dividends received by the Fund with respect to dividends paid on securities lent out will not be qualified dividend income. For this purpose, a qualified non-U.S. corporation means any non-U.S. corporation that is eligible for benefits under a comprehensive income tax treaty with the United States, which includes an exchange of information program or if the stock with respect to which the dividend was paid is readily tradable on an established United States securities market. The term excludes a corporation that is a passive foreign investment company.

Dividends received by the Fund from a REIT or another RIC generally are qualified dividend income only to the extent the dividend distributions are made out of qualified dividend income received by such REIT or RIC. It is expected that dividends received by the Fund from a REIT and distributed to a shareholder generally will be taxable to the shareholder as ordinary income.

For a dividend to be treated as qualified dividend income, the dividend must be received with respect to a share of stock held without being hedged by the Fund, and with respect to a share of the Fund held without being hedged by you, for 61 days during the 121-day period beginning at the date which is 60 days before the date on which such share becomes ex-dividend with respect to such dividend or, in the case of certain preferred stock, 91 days during the 181-day period beginning 90 days before such date.

If your Fund shares are loaned out pursuant to a securities lending arrangement, you may lose the ability to use foreign tax credits passed through by the Fund or to treat Fund dividends paid while the shares are held by the borrower as qualified dividend income.

In general, your distributions are subject to U.S. federal income tax for the year when they are paid. Certain distributions paid in January, however, may be treated as paid on December 31 of the prior year.

If the Fund’s distributions exceed current and accumulated earnings and profits, all or a portion of the distributions made in the taxable year may be recharacterized as a return of capital to shareholders. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and result in a higher capital gain or lower capital loss when those shares on which the distribution was received are sold. Once a shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain, if the shareholder holds shares of the Fund as capital assets.

If you are neither a resident nor a citizen of the United States or if you are a non-U.S. entity, the Fund’s ordinary income dividends (which include distributions of net short-term capital gains) will generally be subject to a 30% U.S. withholding tax, unless a lower treaty rate applies, provided that withholding tax will generally not apply to any gain or income realized by a non-U.S. shareholder in respect of any distributions of long-term capital gains or upon the sale or other disposition of shares of the Fund.

A 30% withholding tax will be imposed on dividends paid after December 31, 2013, and redemption proceeds paid after December 31, 2014, to (i) foreign financial institutions including non-U.S. investment funds unless they agree to collect and disclose to the Internal Revenue Service (“IRS”) information regarding their direct and indirect U.S. account holders and (ii) certain other foreign entities, unless they certify certain information regarding their direct and indirect U.S. owners. To avoid withholding, foreign financial institutions will need to enter into agreements with the IRS that state that they will provide the IRS information, including the name, address and taxpayer identification number of direct and indirect U.S. account holders, comply with due diligence procedures with respect to the identification of U.S. accounts, report to the IRS certain information with respect to U.S. accounts maintained, agree to withhold tax on certain payments made to non-compliant foreign financial institutions or to account holders who fail to provide the required information, and determine certain other information as to their account holders. Other foreign entities will need to provide the name, address, and taxpayer identification number of each substantial U.S. owner or certifications of no substantial U.S. ownership unless certain exceptions apply.

Dividends, interest and capital gains received by the Fund with respect to non-U.S. securities may give rise to withholding and other taxes imposed by non-U.S. countries. Tax conventions between certain countries and the United States may reduce or eliminate such taxes.

If you are a resident or a citizen of the United States, by law, back-up withholding will apply to your distributions and proceeds if you have not provided a taxpayer identification number or social security number and made other required certifications.

Taxes When Shares are Sold. Currently, any capital gain or loss realized upon a sale of Fund shares is generally treated as a long-term gain or loss if the shares have been held for more than one year. Any capital gain or loss realized upon a sale of Fund shares held for one year or less is generally treated as short-term gain or loss, except that any capital loss on the sale of shares held for six months or less is treated as long-term capital loss to the extent that capital gain dividends were paid with respect to such shares. Beginning in 2013, any such capital gains, including from sales of Fund shares or from capital gain dividends, will be included in “net investment income” for purposes of the 3.8% U.S. federal Medicare contribution tax mentioned above.

The foregoing discussion summarizes some of the consequences under current U.S. federal tax law of an investment in the Fund. It is not a substitute for personal tax advice. You may also be subject to state and local taxation on Fund distributions and sales of shares. Consult your personal tax adviser about the potential tax consequences of an investment in shares of the Fund under all applicable tax laws.

Creations and Redemptions. Prior to trading in the secondary market, shares of the Fund are “created” at NAV by market makers, large investors and institutions only in block-size Creation Units of 50,000 shares or multiples thereof. Each “creator” or “Authorized Participant” enters into an authorized participant agreement with the Fund’s distributor, SEI Investments Distribution Co. (the “Distributor”). Only an Authorized Participant may create or redeem Creation Units directly with the Fund. A creation transaction, which is subject to acceptance by the transfer agent, generally

takes place when an Authorized Participant deposits into the Fund a designated portfolio of securities and a specified amount of cash approximating the holdings of the Fund in exchange for a specified number of Creation Units. To the extent practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund.

Similarly, shares can be redeemed only in Creation Units, generally for a designated portfolio of securities and a specified amount of cash held by the Fund (“Fund Securities”). Except when aggregated in Creation Units, shares are not redeemable by the Fund. The prices at which creations and redemptions occur are based on the next calculation of NAV after an order is received in a form described in the authorized participant agreement.

The Fund intends to comply with the U.S. federal securities laws in accepting securities for deposit and satisfying redemptions with redemption securities by, among other means, assuring that any securities accepted for deposit and any securities used to satisfy redemption requests will be sold in transactions that would be exempt from registration under the Securities Act of 1933, as amended (the “1933 Act”). Further, an Authorized Participant that is not a “qualified institutional buyer,” as such term is defined under Rule 144A of the 1933 Act, will not be able to receive Fund Securities that are restricted securities eligible for resale under Rule 144A.

Creations and redemptions must be made through a firm that is either a member of the Continuous Net Settlement System of the National Securities Clearing Corporation or a DTC participant and has executed an agreement with the Distributor with respect to creations and redemptions of Creation Unit aggregations. Information about the procedures regarding creation and redemption of Creation Units (including the cut-off times for receipt of creation and redemption orders) is included in the Fund’s SAI.

Because new shares may be created and issued on an ongoing basis, at any point during the life of the Fund a “distribution,” as such term is used in the 1933 Act, may be occurring. Broker-dealers and other persons are cautioned that some activities on their part may, depending on the circumstances, result in their being deemed participants in a distribution in a manner that could render them statutory underwriters and subject to the prospectus delivery and liability provisions of the 1933 Act. Any determination of whether one is an underwriter must take into account all the relevant facts and circumstances of each particular case.

Broker-dealers should also note that dealers who are not “underwriters” but are participating in a distribution (as contrasted to ordinary secondary transactions), and thus dealing with shares that are part of an “unsold allotment” within the meaning of Section 4(3)(C) of the 1933 Act, would be unable to take advantage of the prospectus delivery exemption provided by Section 4(3) of the 1933 Act. For delivery of prospectuses to exchange members, the prospectus delivery mechanism of Rule 153 under the 1933 Act is available only with respect to transactions on a national securities exchange.

Costs Associated with Creations and Redemptions. Authorized Participants are charged standard creation and redemption transaction fees to offset transfer and other transaction costs associated with the issuance and redemption of Creation

Units. The standard creation and redemption transaction fees are set forth in the table below. The standard creation transaction fee is charged to the Authorized Participant on the day such Authorized Participant creates a Creation Unit, and is the same regardless of the number of Creation Units purchased by the Authorized Participant on the applicable business day. Similarly, the standard redemption transaction fee is charged to the Authorized Participant on the day such Authorized Participant redeems a Creation Unit, and is the same regardless of the number of Creation Units redeemed by the Authorized Participant on the applicable business day. Creations and redemptions for cash (when cash creations and redemptions (in whole or in part) are available or specified) are also subject to an additional charge (up to the maximum amounts shown in the table below). This charge is intended to compensate for brokerage, tax, foreign exchange, execution, market impact and other costs and expenses related to cash transactions. Investors who use the services of a broker or other financial intermediary may pay fees for such services.

The following table shows, as of September 30, 2011, the approximate value of one Creation Unit, standard fees and maximum additional charges for creations and redemptions (as described above):

Householding. Householding is an option available to certain Fund investors. Householding is a method of delivery, based on the preference of the individual investor, in which a single copy of certain shareholder documents can be delivered to investors who share the same address, even if their accounts are registered under different names. Please contact your broker-dealer if you are interested in enrolling in householding and receiving a single copy of prospectuses and other shareholder documents, or if you are currently enrolled in householding and wish to change your householding status.

Distribution

The Distributor distributes Creation Units for the Fund on an agency basis. The Distributor does not maintain a secondary market in shares of the Fund. The Distributor has no role in determining the policies of the Fund or the securities that are purchased or sold by the Fund. The Distributor’s principal address is One Freedom Valley Drive, Oaks, PA 19456.

In addition, BFA or its Affiliates make payments to broker-dealers, banks or other financial intermediaries (together, “intermediaries”) related to marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems, or their making shares of the Fund and

certain other iShares funds available to their customers. Such payments, which may be significant to the intermediary, are not made by the Fund. Rather, such payments are made by BFA or its Affiliates from their own resources, which come directly or indirectly in part from fees paid by the iShares funds complex. Payments of this type are sometimes referred to as revenue-sharing payments. A financial intermediary may make decisions about which investment options it recommends or makes available, or the level of services provided, to its customers based on the revenue-sharing payments it is eligible to receive. Therefore, such payments to an intermediary create conflicts of interest between the intermediary and its customers and may cause the intermediary to recommend the Fund or other iShares funds over another investment. More information regarding these payments is contained in the Fund’s SAI. Please contact your salesperson or other investment professional for more information regarding any such payments his or her firm may receive from BFA or its Affiliates.

Financial Highlights

The financial highlights table is intended to help investors understand the Fund’s financial performance for the past five years. Certain information reflects financial results for a single share of the Fund. The total returns in the table represent the rate that an investor would have earned (or lost) on an investment in the Fund, assuming reinvestment of all dividends and distributions. This information has been audited by PricewaterhouseCoopers LLP, whose report is included, along with the Fund’s financial statements, in the Fund’s Annual Report (available upon request).

Supplemental Information

I. Premium/Discount Information

The table that follows presents information about the differences between the daily market price on secondary markets for shares of the Fund and the Fund’s NAV. NAV is the price at which the Fund issues and redeems shares. It is calculated in accordance with the standard formula for valuing mutual fund shares. The price used to calculate market returns (“Market Price”) of the Fund generally is determined using the midpoint between the highest bid and the lowest offer on the primary securities exchange on which shares of the Fund are listed for trading, as of the time that the Fund’s NAV is calculated. The Fund’s Market Price may be at, above or below its NAV. The NAV of the Fund will fluctuate with changes in the value of its portfolio holdings. The Market Price of the Fund will fluctuate in accordance with changes in its NAV, as well as market supply and demand.

Premiums or discounts are the differences (expressed as a percentage) between the NAV and Market Price of the Fund on a given day, generally at the time the NAV is calculated. A premium is the amount that the Fund is trading above the reported NAV, expressed as a percentage of the NAV. A discount is the amount that the Fund is trading below the reported NAV, expressed as a percentage of the NAV.

The following information shows the frequency of distributions of premiums and discounts for the Fund for each full calendar quarter of 2010 through September 30, 2011.

Each line in the table shows the number of trading days in which the Fund traded within the premium/discount range indicated. The number of trading days in each premium/discount range is also shown as a percentage of the total number of trading days in the period covered by the table. All data presented here represents past performance, which cannot be used to predict future results.

Premium/Discount Range
Number of Days
Percentage of Total Days
Greater than 0.5% 1 0.23%
Between 0.5% and -0.5% 440 99.77
   441 100.00%

II. Total Return Information

The tables that follow present information about the total returns of the Fund and the Underlying Index as of the fiscal year ended July 31, 2011.

“Average Annual Total Returns” represent the average annual change in value of an investment over the periods indicated. “Cumulative Total Returns” represent the total change in value of an investment over the periods indicated.

The Fund’s NAV is the value of one share of the Fund as calculated in accordance with the standard formula for valuing mutual fund shares. The NAV return is based on the NAV of the Fund and the market return is based on the Market Price of the Fund. Market Price is determined by using the midpoint between the highest bid and the lowest offer on the primary stock exchange on which shares of the Fund are listed for trading, as of the time that the Fund’s NAV is calculated. Since shares of the Fund did not trade in the secondary market until after the Fund’s inception, for the period from inception to the first day of secondary market trading in shares of the Fund, the NAV of the Fund is used as a proxy for the Market Price to calculate market returns. Market and NAV returns assume that dividends and capital gain distributions have been reinvested in the Fund at Market Price and NAV, respectively.

An index is a statistical composite that tracks a specified financial market or sector. Unlike the Fund, the Underlying Index does not actually hold a portfolio of securities and therefore does not incur the expenses incurred by the Fund. These expenses negatively impact the performance of the Fund. Also, market returns do not include brokerage commissions that may be payable on secondary market transactions. If brokerage commissions were included, market returns would be lower. The returns shown in the following tables do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption or sale of Fund shares. The investment return and principal value of shares of the Fund will vary with changes in market conditions. Shares of the Fund may be worth more or less than their original cost when they are redeemed or sold in the market. The Fund’s past performance is no guarantee of future results.

Fund Overview

iSHARES® PHLX SOX SEMICONDUCTOR SECTOR INDEX FUND

Ticker: SOXX Stock Exchange: NASDAQ

Investment Objective

The iShares PHLX SOX Semiconductor Sector Index Fund (the “Fund”) seeks investment results that correspond generally to the price and yield performance, before fees and expenses, of the PHLX Semiconductor Sector IndexSM (the “Underlying Index”).

Fees and Expenses

The following table describes the fees and expenses that you will incur if you own shares of the Fund. The investment advisory agreement between iShares Trust (the “Trust”) and BlackRock Fund Advisors (“BFA”) (the “Investment Advisory Agreement”) provides that BFA will pay all operating expenses of the Fund, except interest expenses, taxes, brokerage expenses, future distribution fees or expenses, and extraordinary expenses.

You may also incur usual and customary brokerage commissions when buying or selling shares of the Fund, which are not reflected in the example that follows:

Example. This Example is intended to help you compare the cost of owning shares of the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

3 Years
5 Years
10 Years
$49 $154 $269 $604

Portfolio Turnover. The Fund may pay transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 52% of the average value of its portfolio.

Principal Investment Strategies

The Underlying Index measures the performance of U.S.-traded securities of companies engaged in the semiconductor business. The Underlying Index includes companies engaged in the design, distribution, manufacture and sales of semiconductors.

BFA uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to “beat” the index it tracks and does not seek temporary defensive positions when markets decline or appear overvalued.

Indexing may eliminate the chance that the Fund will substantially outperform the Underlying Index but also may reduce some of the risks of active management, such as poor security selection. Indexing seeks to achieve lower costs and better after-tax performance by keeping portfolio turnover low in comparison to actively managed investment companies.

BFA uses a representative sampling indexing strategy to manage the Fund. “Representative sampling” is an indexing strategy that involves investing in a representative sample of securities that collectively has an investment profile similar to the Underlying Index. The securities selected are expected to have, in the aggregate, investment characteristics (based on factors such as market capitalization and industry weightings), fundamental characteristics (such as return variability and yield) and liquidity measures similar to those of the Underlying Index. The Fund may or may not hold all of the securities in the Underlying Index.

The Fund generally invests at least 90% of its assets in securities of the Underlying Index and in depositary receipts representing securities of the Underlying Index. The Fund may invest the remainder of its assets in securities not included in the Underlying Index, but which BFA believes will help the Fund track the Underlying Index and in other investments including futures contracts, options on futures contracts, options and swaps as well as cash and cash equivalents, including shares of money market funds advised by BFA or its affiliates.

The Fund may lend securities representing up to one-third of the value of the Fund’s total assets (including the value of the collateral received).

The Underlying Index is sponsored by an organization (the “Index Provider”) that is independent of the Fund and BFA. The Index Provider determines the composition and relative weightings of the securities in the Underlying Index and publishes information regarding the

S-2   


Table Of Contents



market value of the Underlying Index. The Fund’s Index Provider is The NASDAQ OMX Group, Inc. (“NASDAQ OMX”).

Industry Concentration Policy. The Fund will concentrate its investments (i.e., hold 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. For purposes of this limitation, securities of the U.S. government (including its agencies and instrumentalities) and repurchase agreements collateralized by U.S. government securities are not considered to be issued by members of any industry.

Summary of Principal Risks

As with any investment, you could lose all or part of your investment in the Fund, and the Fund’s performance could trail that of other investments. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund’s net asset value per share (“NAV”), trading price, yield, total return and ability to meet its investment objective.

Asset Class Risk. Securities in the Underlying Index or in the Fund’s portfolio may underperform in comparison to the general securities markets or other asset classes.

Concentration Risk. To the extent that the Fund’s investments are concentrated in a particular issuer, region, country, market, industry or asset class, the Fund may be susceptible to loss due to adverse occurrences affecting that issuer, region, country, market, industry or asset class.

Equity Securities Risk. Equity securities are subject to changes in value and their values may be more volatile than other asset classes.

Issuer Risk. Fund performance depends on the performance of individual securities to which the Fund has exposure. Changes to the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA’s investment management strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares, losses from trading in secondary markets, periods of high volatility and disruption in the creation/redemption process of the Fund. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV.

Non-Diversification Risk. The Fund may invest a large percentage of its assets in securities issued by or representing a small number of issuers. As a result, the Fund’s performance may depend on the performance of a small number of issuers.

Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers are subject to the risks associated with investing in those non-U.S. markets, such as heightened risks of inflation or

S-3   


Table Of Contents



nationalization. The Fund may lose money due to political, economic and geographic events affecting a non-U.S. issuer or market.

Passive Investment Risk. The Fund is not actively managed and BFA does not attempt to take defensive positions under any market conditions, including declining markets.

Securities Lending Risk. The Fund may engage in securities lending. Securities lending involves the risk that the Fund may lose money because the borrower of the Fund’s loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Technology Sector Risk. Technology companies may have limited product lines, markets, financial resources or personnel. Technology companies typically face intense competition and potentially rapid product obsolescence. They are also heavily dependent on intellectual property rights and may be adversely affected by loss or impairment of those rights.

Tracking Error Risk. The performance of the Fund may diverge from that of the Underlying Index. Because the Fund employs a representative sampling strategy, the Fund may experience tracking error to a greater extent than a fund that seeks to replicate an index.

U.S. Economic Risk. The United States is a significant trading partner of countries in which the Fund invests. Any change in the U.S. economy may have an adverse effect on the Fund.

Performance Information

The bar chart and table that follow show how the Fund has performed on a calendar year basis and provide an indication of the risks of investing in the Fund. Both assume that all dividends and distributions have been reinvested in the Fund. On October 15, 2010, the name of the Fund changed from the iShares S&P North American Technology-Semiconductors Index Fund to the iShares PHLX SOX Semiconductor Sector Index Fund to reflect a change in the Fund’s Index Provider from Standard & Poors Financial Services LLC to NASDAQ OMX and a change in the Fund’s Underlying Index from S&P North American Technology-Semiconductors Index to PHLX Semiconductor Sector Index. The performance of both the former Underlying Index and the current Underlying Index are shown. Past performance (before and after taxes) does not necessarily indicate how the Fund will perform in the future. Supplemental information about the Fund’s performance is shown under the heading Total Return Information in the Supplemental Information section of the Fund’s prospectus (the “Prospectus”).

Year by Year Returns1 (Years Ended December 31)


1 The Fund’s total return for the nine months ended September 30, 2011 was -17.05%.

The best calendar quarter return during the periods shown above was 25.25% in the 2nd quarter of 2003; the worst was
-38.49% in the 3rd quarter of 2002.

1 After-tax returns in the table above are calculated using the historical highest individual U.S. federal marginal income tax rates and do not reflect the impact of state or local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown, and after-tax returns shown are not relevant to tax-exempt investors or investors who hold shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts (“IRAs”). Fund returns after taxes on distributions and sale of Fund shares are calculated assuming that an investor has sufficient capital gains of the same character from other investments to offset any capital losses from the sale of Fund shares. As a result, Fund returns after taxes on distributions and sale of Fund shares may exceed Fund returns before taxes and/or returns after taxes on distributions.

Management

Investment Adviser. BlackRock Fund Advisors.

Portfolio Managers. Rene Casis, Diane Hsiung and Greg Savage (the “Portfolio Managers”) are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager supervises a portfolio management team. Mr. Casis, Ms. Hsiung and Mr. Savage have been Portfolio Managers of the Fund since 2010, 2008 and 2008, respectively.

Purchase and Sale of Fund Shares

The Fund is an exchange-traded fund (commonly referred to as an “ETF”). Individual Fund shares may only be purchased and sold on a national securities exchange through a broker-dealer. The price of Fund shares is based on market price, and because ETF shares trade at market prices rather than NAV, shares may trade at a price greater than NAV (a premium) or less than NAV (a discount). The Fund will only issue or redeem shares that have been aggregated into blocks of 50,000 shares or multiples thereof (“Creation Units”) to authorized participants who have entered into agreements with the Fund’s distributor. The Fund generally will issue or redeem Creation Units in return for a designated portfolio of securities (and an amount of cash) that the Fund specifies each day.

Tax Information

The Fund intends to make distributions that may be taxable to you as ordinary income or capital gains, unless you are investing through a tax-deferred arrangement such as a 401(k) plan or an IRA.

Payments to Broker-Dealers and other Financial Intermediaries

If you purchase shares of the Fund through a broker-dealer or other financial intermediary (such as a bank), BFA or other related companies may pay the intermediary for marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems or other services related to the sale or promotion of the Fund. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.

More Information About the Fund

This Prospectus contains important information about investing in the Fund. Please read this Prospectus carefully before you make any investment decisions. Additional information regarding the Fund is available at www.iShares.com.

BFA is the investment adviser to the Fund. Shares of the Fund are listed for trading on The NASDAQ Stock Market (“NASDAQ”). The market price for a share of the Fund may be different from the Fund’s most recent NAV.

ETFs are funds that trade like other publicly-traded securities. The Fund is designed to track an index. Similar to shares of an index mutual fund, each share of the Fund represents a partial ownership in an underlying portfolio of securities intended to track a market index. Unlike shares of a mutual fund, which can be bought and redeemed from the issuing fund by all shareholders at a price based on NAV, shares of the Fund may be purchased or redeemed directly from the Fund at NAV solely by authorized participants. Also unlike shares of a mutual fund, shares of the Fund are listed on a national securities exchange and trade in the secondary market at market prices that change throughout the day.

The Fund invests in a particular segment of the securities markets and seeks to track the performance of a securities index that generally is not representative of the market as a whole. The Fund is designed to be used as part of broader asset allocation strategies. Accordingly, an investment in the Fund should not constitute a complete investment program.

An index is a theoretical financial calculation while the Fund is an actual investment portfolio. The performance of the Fund and the Underlying Index may vary due to transaction costs, non-U.S. currency valuations, asset valuations, corporate actions (such as mergers and spin-offs), timing variances and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions (such as diversification requirements) that apply to the Fund but not to the Underlying Index or to the use of representative sampling. “Tracking error” is the difference between the performance (return) of the Fund’s portfolio and that of the Underlying Index. BFA expects that, over time, the Fund’s tracking error will not exceed 5%. Because the Fund uses a representative sampling indexing strategy, it can be expected to have a larger tracking error than if it used a replication indexing strategy. “Replication” is an indexing strategy in which a fund invests in substantially all of the securities in its underlying index in approximately the same proportions as in the underlying index.

An investment in the Fund is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, BFA or any of its affiliates.

The Fund’s investment objective and the Underlying Index may be changed without shareholder approval.

A Further Discussion of Principal Risks

The Fund is subject to various risks, including the principal risks noted below, any of which may adversely affect the Fund’s NAV, trading price, yield, total return and ability to meet its investment objective. You could lose all or part of your investment in the Fund, and the Fund could underperform other investments.

Asset Class Risk. The securities in the Underlying Index or in the Fund’s portfolio may underperform the returns of other securities or indexes that track other industries, groups of industries, markets, asset classes or sectors. Various types of securities or indexes tend to experience cycles of outperformance and underperformance in comparison to the general securities markets.

Concentration Risk. To the extent that the Fund’s portfolio reflects the Underlying Index’s concentration in the securities of a particular issuer or issuers in a particular country, group of countries, region, market, industry, group of industries, sector or asset class, the Fund may be adversely affected by the performance of those securities, may be subject to increased price volatility and may be more susceptible to adverse economic, market, political or regulatory occurrences affecting that issuer, country, group of countries, region, market, industry, group of industries, sector or asset class.

Equity Securities Risk. The Fund invests in equity securities, which are subject to changes in value that may be attributable to market perception of a particular issuer or to general stock market fluctuations that affect all issuers. Investments in equity securities may be more volatile than investments in other asset classes.

Issuer Risk. The performance of the Fund depends on the performance of individual securities to which the Fund has exposure. Any issuer of these securities may perform poorly, causing the value of its securities to decline. Poor performance may be caused by poor management decisions, competitive pressures, changes in technology, expiration of patent protection, disruptions in supply, labor problems or shortages, corporate restructurings, fraudulent disclosures or other factors. Issuers may, in times of distress or at their own discretion, decide to reduce or eliminate dividends, which may also cause their stock prices to decline.

Management Risk. The Fund may not fully replicate the Underlying Index and may hold securities not included in the Underlying Index. As a result, the Fund is subject to the risk that BFA’s investment management strategy, the implementation of which is subject to a number of constraints, may not produce the intended results.

Market Risk. The Fund could lose money due to short-term market movements and over longer periods during market downturns. Securities may decline in value due to factors affecting securities markets generally or particular industries represented in the markets. The value of a security may decline due to general market conditions, economic trends or events that are not specifically related to the issuer of the security or to factors that affect a particular industry or industries. During a general downturn in the securities markets, multiple asset classes may be negatively affected.

Market Trading Risk

Absence of Active Market. Although shares of the Fund are listed for trading on one or more stock exchanges, there can be no assurance that an active trading market for such shares will develop or be maintained.

Risk of Secondary Listings. The Fund’s shares may be listed or traded on U.S. and non-U.S. stock exchanges other than the U.S. stock exchange where the Fund’s primary listing is maintained. There can be no assurance that the Fund’s shares will continue to trade on any such stock exchange or in any market or that the Fund’s shares will continue to meet the requirements for listing or trading on any exchange or in any market. The Fund’s shares may be less actively traded in certain markets than others, and investors are subject to the execution and settlement risks and market standards of the market where they or their broker direct their trades for execution. Certain information available to investors who trade Fund shares on a U.S. stock exchange during regular U.S. market hours may not be available to investors who trade in other markets, which may result in secondary market prices in such markets being less efficient.

Secondary Market Trading Risk. Shares of the Fund may trade in the secondary market at times when the Fund does not accept orders to purchase or redeem shares. At such times, shares may trade in the secondary market with more significant premiums or discounts than might be experienced at times when the Fund accepts purchase and redemption orders.

Secondary market trading in Fund shares may be halted by a stock exchange because of market conditions or other reasons. In addition, trading in Fund shares on a stock exchange or in any market may be subject to trading halts caused by extraordinary market volatility pursuant to “circuit breaker” rules on the stock exchange or market. There can be no assurance that the requirements necessary to maintain the listing or trading of Fund shares will continue to be met or will remain unchanged.

Shares of the Fund May Trade at Prices Other Than NAV. Shares of the Fund trade on stock exchanges at prices at, above or below their most recent NAV. The NAV of the Fund is calculated at the end of each business day and fluctuates with changes in the market value of the Fund’s holdings since the most recent calculation. The trading prices of the Fund’s shares fluctuate continuously throughout trading hours based on market supply and demand rather than NAV. The trading prices of the Fund’s shares may deviate significantly from NAV during periods of market volatility. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV. However, because shares can be created and redeemed in Creation Units at NAV (unlike shares of many closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their NAVs), BFA believes that large discounts or premiums to the NAV of the Fund are not likely to be sustained over the long-term. While the creation/redemption feature is designed to make it likely that the Fund’s shares normally will trade on stock exchanges at prices close to the Fund’s next calculated NAV, exchange prices are not expected to correlate exactly with the Fund’s NAV due to timing reasons as well as market supply and demand factors. In addition, disruptions to creations and

redemptions or extreme market volatility may result in trading prices for shares of the Fund that differ significantly from its NAV.

Costs of Buying or Selling Fund Shares. Buying or selling Fund shares on an exchange involves two types of costs that apply to all securities transactions. When buying or selling shares of the Fund through a broker, you will likely incur a brokerage commission or other charges imposed by brokers as determined by that broker. In addition, you may incur the cost of the “spread” – that is, the difference between what investors are willing to pay for Fund shares (the “bid” price) and the price at which they are willing to sell Fund shares (the “ask” price). Because of the costs inherent in buying or selling Fund shares, frequent trading may detract significantly from investment results and an investment in Fund shares may not be advisable for investors who anticipate regularly making small investments.

Non-Diversification Risk. The Fund is classified as “non-diversified.” This means that the Fund may invest a large percentage of its assets in securities issued by or representing a small number of issuers. As a result, the Fund may be more susceptible to the risks associated with these particular issuers, or to a single economic, political or regulatory occurrence affecting these issuers.

Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers are subject to all of the risks of investing in the markets where such issuers are located, including heightened risks of inflation or nationalization and market fluctuations caused by economic and political developments. As a result of investing in non-U.S. securities, the Fund may be subject to increased risk of loss caused by any of the factors listed below:

  • Lower levels of liquidity and market efficiency;
  • Greater securities price volatility;
  • Exchange rate fluctuations and exchange controls;
  • Less availability of public information about issuers;
  • Limitations on foreign ownership of securities;
  • Imposition of withholding or other taxes;
  • Imposition of restrictions on the expatriation of the funds or other assets of the Fund;
  • Higher transaction and custody costs and delays in settlement procedures;
  • Difficulties in enforcing contractual obligations;
  • Lower levels of regulation of the securities market;
  • Weaker accounting, disclosure and reporting requirements; and
  • Legal principles related to corporate governance, directors’ fiduciary duties and liabilities and stockholders’ rights in markets in which the Fund invests may differ and/or may not be as extensive or protective as those that apply in the United States.

Passive Investment Risk. The Fund is not actively managed and may be affected by a general decline in market segments related to the Underlying Index. The Fund invests in securities included in, or representative of, the Underlying Index regardless of their

investment merits. BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

Securities Lending Risk. The Fund may engage in securities lending. Securities lending involves the risk that the Fund may lose money because the borrower of the Fund’s loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for the loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Technology Sector Risk. The Fund invests in technology companies, which face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Technology companies may have limited product lines, markets, financial resources or personnel. The products of technology companies may face obsolescence due to rapid technological developments and frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Companies in the technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies.

Tracking Error Risk. Imperfect correlation between the Fund’s portfolio securities and those in the Underlying Index, rounding of prices, changes to the Underlying Index and regulatory requirements may cause tracking error, which is the divergence of the Fund’s performance from that of the Underlying Index. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Underlying Index does not. Because the Fund employs a representative sampling strategy, the Fund may experience tracking error to a greater extent than a fund that seeks to replicate an index.

U.S. Economic Risk. The United States is a significant, and in some cases the most significant, trading partner of or foreign investor in certain emerging markets and the economies of these countries may be particularly affected by adverse changes in the U.S. economy. Decreasing U.S. imports, new trade regulations, changes in the U.S. dollar exchange rates or a recession in the United States may have a material adverse effect on the economies of these nations and, as a result, securities to which the Fund has exposure.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

Asian Economic Risk. Certain Asian economies have experienced over-extension of credit, currency devaluations and restrictions, high unemployment, high inflation, decreased exports and economic recessions. Economic events in any one Asian country may have a significant economic effect on the entire Asian region, as well as on major trading partners outside Asia, and any adverse event in the Asian markets may have a significant adverse effect on other Asian economies.

Portfolio Holdings Information

A description of the Trust’s policies and procedures with respect to the disclosure of the Fund’s portfolio securities is available in the Fund’s Statement of Additional Information (“SAI”). The top holdings of the Fund can be found at www.iShares.com. Fund fact sheets provide information regarding the Fund’s top holdings and may be requested by calling 1-800-iShares (1-800-474-2737).

Management

Investment Adviser. As investment adviser, BFA has overall responsibility for the general management and administration of the Trust. BFA provides an investment program for the Fund and manages the investment of the Fund’s assets. In managing the Fund, BFA may draw upon the research and expertise of its asset management affiliates with respect to certain portfolio securities. In seeking to achieve the Fund’s investment objective, BFA uses teams of portfolio managers, investment strategists and other investment specialists. This team approach brings together many disciplines and leverages BFA’s extensive resources.

Pursuant to the Investment Advisory Agreement between BFA and the Trust (entered into on behalf of the Fund), BFA is responsible for substantially all expenses of the Fund, except interest expenses, taxes, brokerage expenses, future distribution fees or expenses and extraordinary expenses.

For its investment advisory services to the Fund, BFA is entitled to receive a management fee from the Fund corresponding to the Fund’s allocable portion of an aggregate management fee based on the aggregate average daily net assets of the following iShares funds: iShares PHLX SOX Semiconductor Sector Index Fund, iShares S&P Global Clean Energy Index Fund, iShares S&P Global Consumer Discretionary Sector Index Fund, iShares S&P Global Consumer Staples Sector Index Fund, iShares S&P Global Energy Sector Index Fund, iShares S&P Global Financials Sector Index Fund, iShares S&P Global Healthcare Sector Index Fund, iShares S&P Global Industrials Sector Index Fund, iShares S&P Global Infrastructure Index Fund, iShares S&P Global Materials Sector Index Fund, iShares S&P Global Nuclear Energy Index Fund, iShares S&P Global Technology Sector Index Fund, iShares S&P Global Telecommunications Sector Index Fund, iShares S&P Global Timber & Forestry Index Fund, iShares S&P Global Utilities Sector Index Fund, iShares S&P North American Natural Resources Sector Index Fund, iShares S&P North American Technology Sector Index Fund, iShares S&P North American Technology-Multimedia Networking Index Fund and iShares S&P North American Technology-Software Index Fund. The aggregate management fee is calculated as follows: 0.48% per annum of the aggregate net assets less than or equal to $10.0 billion, plus 0.43% per annum of the aggregate net assets over $10.0 billion, up to and including $20.0 billion, plus 0.38% per annum of the aggregate net assets in excess of $20.0 billion. As calculated on July 31, 2011, for its investment advisory services to the Fund, BFA is entitled to receive a management fee from the Fund, based on a percentage of the Fund’s average daily net assets, at an annual rate of 0.48%.

BFA is located at 400 Howard Street, San Francisco, CA 94105. It is a wholly owned subsidiary of BTC, which in turn is indirectly wholly-owned by BlackRock, Inc. (“BlackRock”). As of September 30, 2011, BTC and its affiliates, including BFA and BlackRock, provided investment advisory services for assets in excess of $3.35 trillion. BFA, BTC, BlackRock Execution Services, BlackRock and their affiliates deal, trade and invest for their own accounts in the types of securities in which the Fund may also invest.

A discussion regarding the basis for the Trust’s Board of Trustees’ (the “Board”) approval of the Investment Advisory Agreement with BFA is available in the Fund’s annual report for the period ended July 31.

Portfolio Managers. Rene Casis, Diane Hsiung and Greg Savage are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager is responsible for various functions related to portfolio management, including, but not limited to, investing cash inflows, coordinating with members of his or her portfolio management team to focus on certain asset classes, implementing investment strategy, researching and reviewing investment strategy and overseeing members of his or her portfolio management team that have more limited responsibilities.

Rene Casis has been employed by BFA (formerly, Barclays Global Fund Advisors (“BGFA”)) and BTC (formerly, Barclays Global Investors, N.A. (“BGI”)) as a senior portfolio manager since 2009. From 2005 to 2009, Mr. Casis was a trader at Barclays Capital. Prior to that, Mr. Casis was a portfolio manager from 2000 to 2005 for BGFA and BGI. Mr. Casis has been a Portfolio Manager of the Fund since 2010.

Diane Hsiung has been employed by BFA and BTC as a senior portfolio manager since 2007. Prior to that, Ms. Hsiung was a portfolio manager from 2002 to 2006 for BGFA and BGI. Ms. Hsiung has been a Portfolio Manager of the Fund since 2008.

Greg Savage has been employed by BFA and BTC as a senior portfolio manager since 2006. Prior to that, Mr. Savage was a portfolio manager from 2001 to 2006 for BGFA and BGI. Mr. Savage has been a Portfolio Manager of the Fund since 2008.

The Fund’s SAI provides additional information about the Portfolio Managers’ compensation, other accounts managed by the Portfolio Managers and the Portfolio Managers’ ownership (if any) of shares in the Fund.

Administrator, Custodian and Transfer Agent. State Street Bank and Trust Company (“State Street”) is the administrator, custodian and transfer agent for the Fund.

Conflicts of Interest. BFA wants you to know that there are certain entities with which BFA has relationships that may give rise to conflicts of interest, or the appearance of conflicts of interest. These entities include the following: BFA’s affiliates (including BlackRock and The PNC Financial Services Group, Inc., and each of their affiliates, directors, partners, trustees, managing members, officers and employees (collectively, the “Affiliates”)) and BlackRock’s significant shareholder, Barclays Bank PLC and its affiliates, including Barclays PLC (each, an “Entity” and together, the “Entities”).

The activities of BFA, the Affiliates and the Entities in the management of, or their interest in, their own accounts and other accounts they manage, may present conflicts of interest that could disadvantage the Fund and its shareholders. BFA and its Affiliates or the Entities provide investment management services to other funds and discretionary managed accounts that may follow an investment program similar to that of the Fund. BFA, its Affiliates and the Entities are involved worldwide with a broad spectrum of financial services and asset management activities and may engage in the ordinary course of business in activities in which their interests or the interests of their clients may conflict with those of the Fund. BFA, one or more of the Affiliates or the Entities acts, or may act, as an investor, investment banker, research provider, investment manager, financier, underwriter, advisor, market maker, trader, prime broker, lender, agent or principal, and have other direct and indirect interests, in securities, currencies and other instruments in which the Fund may directly or indirectly invest. Thus, it is likely that the Fund will have multiple business relationships with and will invest in, engage in transactions with, make voting decisions with respect to, or obtain services from, entities for which BFA, an Affiliate or an Entity performs or seeks to perform investment banking or other services.

BFA or one or more Affiliates or Entities may engage in proprietary trading and advise accounts and funds that have investment objectives similar to those of the Fund and/or that engage in and compete for transactions in the same types of securities, currencies and other instruments as the Fund, including in securities issued by other open-end and closed-end investment management companies, including investment companies that are affiliated with the Fund and BFA, to the extent permitted under the Investment Company Act of 1940, as amended (the “1940 Act”). The trading activities of BFA, these Affiliates and Entities are carried out without reference to positions held directly or indirectly by the Fund and may result in BFA, an Affiliate or an Entity having positions that are adverse to those of the Fund.

No Affiliate or Entity is under any obligation to share any investment opportunity, idea or strategy with the Fund. As a result, an Affiliate or an Entity may compete with the Fund for appropriate investment opportunities. As a result of this and several other factors, the results of the Fund’s investment activities may differ from those of an Affiliate or an Entity and of other accounts managed by an Affiliate or an Entity, and it is possible that the Fund could sustain losses during periods in which one or more Affiliates or Entities and other accounts achieve profits on their trading for proprietary or other accounts. The opposite result is also possible.

The Fund may, from time to time, enter into transactions in which BFA or an Affiliate’s or an Entity’s clients have an interest adverse to the Fund. Furthermore, transactions undertaken by Affiliate-advised clients may adversely impact the Fund. Transactions by one or more Affiliate- or Entity-advised clients or BFA may have the effect of diluting or otherwise disadvantaging the values, prices or investment strategies of the Fund.

An Entity may maintain securities indices as part of its product offerings. Index-based funds seek to track the performance of securities indices and may use the name of the index in the fund name. Index providers, including the Entities, may be paid licensing fees for use of their indices or index names. Entities will not be obligated to license their indices to BFA and its Affiliates, and BFA and its Affiliates will not be assured that

the terms of any index licensing agreement with the Entities will be as favorable as those terms offered to other index licensees.

The Fund’s activities may be limited because of regulatory restrictions applicable to one or more Affiliates or Entities, and/or their internal policies designed to comply with such restrictions. In addition, the Fund may invest in securities of companies with which an Affiliate or an Entity has or is trying to develop investment banking relationships or in which an Affiliate or an Entity has significant debt or equity investments. The Fund also may invest in securities of companies for which an Affiliate or an Entity provides or may some day provide research coverage. An Affiliate or an Entity may have business relationships with and purchase or distribute or sell services or products from or to distributors, consultants or others who recommend the Fund or who engage in transactions with or for the Fund, and may receive compensation for such services. The Fund may also make brokerage and other payments to Affiliates or Entities in connection with the Fund’s portfolio investment transactions.

Pursuant to a securities lending program approved by the Board, the Fund has retained an Affiliate of BFA to serve as the securities lending agent for the Fund to the extent that the Fund participates in the securities lending program. For these services, the lending agent may receive a fee from the Fund, including a fee based on the returns earned on the Fund’s investment of the cash received as collateral for any loaned securities. In addition, one or more Affiliates may be among the entities to which the Fund may lend its portfolio securities under the securities lending program.

The activities of BFA, the Affiliates or Entities may give rise to other conflicts of interest that could disadvantage the Fund and its shareholders. BFA has adopted policies and procedures designed to address these potential conflicts of interest. See the Fund’s SAI for further information.

Shareholder Information

Additional shareholder information, including how to buy and sell shares of the Fund, is available free of charge by calling toll-free: 1-800-iShares (1-800-474-2737) or visiting our website at www.iShares.com.

Buying and Selling Shares. Shares of the Fund may be acquired or redeemed directly from the Fund only in Creation Units or multiples thereof, as discussed in the Creations and Redemptions section of this Prospectus. Only an Authorized Participant (as defined in the Creations and Redemptions section) may engage in creation or redemption transactions directly with the Fund. Once created, shares of the Fund generally trade in the secondary market in amounts less than a Creation Unit.

Shares of the Fund are listed on a national securities exchange for trading during the trading day. Shares can be bought and sold throughout the trading day like shares of other publicly-traded companies. The Trust does not impose any minimum investment for shares of the Fund purchased on an exchange. The Fund’s shares trade under the trading symbol “SOXX.”

Buying or selling Fund shares on an exchange involves two types of costs that may apply to all securities transactions. When buying or selling shares of the Fund through a broker, you will likely incur a brokerage commission or other charges determined by

your broker. The commission is frequently a fixed amount and may be a significant proportional cost for investors seeking to buy or sell small amounts of shares. In addition, you may incur the cost of the “spread” – that is, any difference between the bid price and the ask price. The spread varies over time for shares of the Fund based on its trading volume and market liquidity, and is generally lower if the Fund has a lot of trading volume and market liquidity, and higher if the Fund has little trading volume and market liquidity.

The Board has adopted a policy of not monitoring for frequent purchases and redemptions of Fund shares (“frequent trading”) that appear to attempt to take advantage of a potential arbitrage opportunity presented by a lag between a change in the value of the Fund’s portfolio securities after the close of the primary markets for the Fund’s portfolio securities and the reflection of that change in the Fund’s NAV (“market timing”), because the Fund generally sells and redeems its shares directly through transactions that are in-kind and/or for cash, subject to the conditions described below under Creations and Redemptions. The Board has not adopted a policy of monitoring for other frequent trading activity because shares of the Fund are listed for trading on a national securities exchange.

The national securities exchange on which the Fund’s shares are listed is open for trading Monday through Friday and is closed on weekends and the following holidays: New Year’s Day, Martin Luther King, Jr. Day, Presidents’ Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day. The Fund’s primary listing exchange is NASDAQ.

Section 12(d)(1) of the 1940 Act restricts investments by investment companies in the securities of other investment companies. Registered investment companies are permitted to invest in the Fund beyond the limits set forth in Section 12(d)(1), subject to certain terms and conditions set forth in SEC rules or in an SEC exemptive order issued to the Trust. In order for a registered investment company to invest in shares of the Fund beyond the limitations of Section 12(d)(1) pursuant to the exemptive relief obtained by the Trust, the registered investment company must enter into an agreement with the Trust.

Book Entry. Shares of the Fund are held in book-entry form, which means that no stock certificates are issued. The Depository Trust Company (“DTC”) or its nominee is the record owner of all outstanding shares of the Fund and is recognized as the owner of all shares for all purposes.

Investors owning shares of the Fund are beneficial owners as shown on the records of DTC or its participants. DTC serves as the securities depository for shares of the Fund. DTC participants include securities brokers and dealers, banks, trust companies, clearing corporations and other institutions that directly or indirectly maintain a custodial relationship with DTC. As a beneficial owner of shares, you are not entitled to receive physical delivery of stock certificates or to have shares registered in your name, and you are not considered a registered owner of shares. Therefore, to exercise any right as an owner of shares, you must rely upon the procedures of DTC and its participants. These procedures are the same as those that apply to any other securities that you hold in book-entry or “street name” form.

Share Prices. The trading prices of the Fund’s shares in the secondary market generally differ from the Fund’s daily NAV and are affected by market forces such as supply and demand, economic conditions and other factors. Information regarding the intraday value of shares of the Fund, also known as the “indicative optimized portfolio value” (“IOPV”), is disseminated every 15 seconds throughout the trading day by the national securities exchange on which the Fund’s shares are listed or by market data vendors or other information providers. The IOPV is based on the current market value of the securities and/or cash required to be deposited in exchange for a Creation Unit. The IOPV does not necessarily reflect the precise composition of the current portfolio of securities held by the Fund at a particular point in time or the best possible valuation of the current portfolio. Therefore, the IOPV should not be viewed as a “real-time” update of the Fund’s NAV, which is computed only once a day. The IOPV is generally determined by using both current market quotations and/or price quotations obtained from broker-dealers that may trade in the portfolio securities held by the Fund. The quotations of certain Fund holdings may not be updated during U.S. trading hours if such holdings do not trade in the United States. The Fund is not involved in, or responsible for, the calculation or dissemination of the IOPV and makes no representation or warranty as to its accuracy.

Determination of Net Asset Value. The NAV of the Fund normally is determined once daily Monday through Friday, generally as of the regularly scheduled close of business of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m., Eastern time) on each day that the NYSE is open for trading, based on prices at the time of closing provided that (a) any Fund assets or liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers (as detailed below) and (b) U.S. fixed income assets may be valued as of the announced closing time for trading in fixed income instruments in a particular market or exchange. The NAV of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets held by the Fund, and its liabilities, are determined pursuant to valuation policies and procedures approved by the Board. The Fund’s assets and liabilities are valued primarily on the basis of market quotations.

Equity investments are valued at market value, which is generally determined using the last reported official closing price or last trading price on the exchange or market on which the security is primarily traded at the time of valuation.

The Fund invests in foreign securities. Foreign currency exchange rates are generally determined as of 4:00 p.m., London time. Foreign securities owned by the Fund may trade on weekends or other days when the Fund does not price its shares. As a result, the Fund’s NAV may change on days when Authorized Participants will not be able to purchase or redeem Fund shares.

Generally, trading in foreign securities, U.S. government securities, money market instruments and certain fixed-income securities is substantially completed each day at various times prior to the close of business on the NYSE. The values of such securities used in computing the NAV of the Fund are determined as of such times.

When market quotations are not readily available or are believed by BFA to be unreliable, the Fund’s investments are valued at fair value. Fair value determinations are made by BFA in accordance with policies and procedures approved by the Fund’s Board. BFA may conclude that a market quotation is not readily available or is unreliable if a security or other asset or liability does not have a price source due to its lack of liquidity, if a market quotation differs significantly from recent price quotations or otherwise no longer appears to reflect fair value, where the security or other asset or liability is thinly traded, or where there is a significant event subsequent to the most recent market quotation. A “significant event” is an event that, in the judgment of BFA, is likely to cause a material change to the closing market price of the asset or liability held by the Fund. Foreign securities whose values are affected by volatility that occurs in U.S. markets on a trading day after the close of foreign securities markets may be fair valued.

Fair value represents a good faith approximation of the value of an asset or liability. The fair value of an asset or liability held by the Fund is the amount the Fund might reasonably expect to receive from the current sale of that asset or the cost to extinguish that liability in an arm’s-length transaction. Valuing the Fund’s investments using fair value pricing will result in prices that may differ from current market valuations and that may not be the price at which those investments could have been sold during the period in which the particular fair values were used. Use of fair value prices and certain current market valuations could result in a difference between the prices used to calculate the Fund’s NAV and the prices used by the Underlying Index, which, in turn, could result in a difference between the Fund’s performance and the performance of the Underlying Index.

The value of assets or liabilities denominated in non-U.S. currencies will be converted into U.S. dollars using exchange rates deemed appropriate by BFA as investment adviser. Use of a rate different from the rate used by the Index Provider may adversely affect the Fund’s ability to track the Underlying Index.

Dividends and Distributions

General Policies. Dividends from net investment income, if any, generally are declared and paid quarterly by the Fund. Distributions of net realized securities gains, if any, generally are declared and paid once a year, but the Trust may make distributions on a more frequent basis for the Fund. The Trust reserves the right to declare special distributions if, in its reasonable discretion, such action is necessary or advisable to preserve its status as a regulated investment company (“RIC”) or to avoid imposition of income or excise taxes on undistributed income or realized gains.

Dividends and other distributions on shares of the Fund are distributed on a pro rata basis to beneficial owners of such shares. Dividend payments are made through DTC participants and indirect participants to beneficial owners then of record with proceeds received from the Fund.

Dividend Reinvestment Service. No dividend reinvestment service is provided by the Trust. Broker-dealers may make available the DTC book-entry Dividend Reinvestment Service for use by beneficial owners of the Fund for reinvestment of their dividend distributions. Beneficial owners should contact their broker to determine the

availability and costs of the service and the details of participation therein. Brokers may require beneficial owners to adhere to specific procedures and timetables. If this service is available and used, dividend distributions of both income and realized gains will be automatically reinvested in additional whole shares of the Fund purchased in the secondary market.

Taxes. As with any investment, you should consider how your investment in shares of the Fund will be taxed. The tax information in this Prospectus is provided as general information, based on current law. You should consult your own tax professional about the tax consequences of an investment in shares of the Fund.

Unless your investment in Fund shares is made through a tax-exempt entity or tax-deferred retirement account, such as an IRA, you need to be aware of the possible tax consequences when the Fund makes distributions or you sell Fund shares.

Taxes on Distributions. Distributions from the Fund’s net investment income (other than qualified dividend income), including distributions of income from securities lending and distributions out of the Fund’s net short-term capital gains, if any, are taxable to you as ordinary income. Distributions by the Fund of net long-term capital gains in excess of net short-term capital losses (capital gain dividends) are taxable to you as long-term capital gains, generally at a 15% tax rate (0% at certain income levels), regardless of how long you have held the Fund’s shares. Distributions by the Fund that qualify as qualified dividend income are taxable to you at long-term capital gain rates for taxable years beginning on or before December 31, 2012. The 15% and 0% tax rates expire for taxable years beginning after December 31, 2012. Maximum long-term capital gain income tax rates are scheduled to rise to 20% in 2013. Beginning in 2013, a 3.8% U.S. federal Medicare contribution tax will be imposed on “net investment income,” including interest, dividends, and capital gains, of U.S. individuals with income exceeding $200,000 (or $250,000 if married and filing jointly), and of estates and trusts.

Dividends will be qualified dividend income to you if they are attributable to qualified dividend income received by the Fund. Generally, qualified dividend income includes dividend income from taxable U.S. corporations and qualified non-U.S. corporations, provided that the Fund satisfies certain holding period requirements in respect of the stock of such corporations and has not hedged its position in the stock in certain ways. Substitute dividends received by the Fund with respect to dividends paid on securities lent out will not be qualified dividend income. For this purpose, a qualified non-U.S. corporation means any non-U.S. corporation that is eligible for benefits under a comprehensive income tax treaty with the United States, which includes an exchange of information program or if the stock with respect to which the dividend was paid is readily tradable on an established United States securities market. The term excludes a corporation that is a passive foreign investment company.

Dividends received by the Fund from a real estate investment trust (“REIT”) or another RIC generally are qualified dividend income only to the extent the dividend distributions are made out of qualified dividend income received by such REIT or RIC. It is expected that dividends received by the Fund from a REIT and distributed to a shareholder generally will be taxable to the shareholder as ordinary income.

For a dividend to be treated as qualified dividend income, the dividend must be received with respect to a share of stock held without being hedged by the Fund, and with respect to a share of the Fund held without being hedged by you, for 61 days during the 121-day period beginning at the date which is 60 days before the date on which such share becomes ex-dividend with respect to such dividend or, in the case of certain preferred stock, 91 days during the 181-day period beginning 90 days before such date.

If your Fund shares are loaned out pursuant to a securities lending arrangement, you may lose the ability to use foreign tax credits passed through by the Fund or to treat Fund dividends paid while the shares are held by the borrower as qualified dividend income.

In general, your distributions are subject to U.S. federal income tax for the year when they are paid. Certain distributions paid in January, however, may be treated as paid on December 31 of the prior year.

If the Fund’s distributions exceed current and accumulated earnings and profits, all or a portion of the distributions made in the taxable year may be recharacterized as a return of capital to shareholders. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and result in a higher capital gain or lower capital loss when those shares on which the distribution was received are sold. Once a shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain, if the shareholder holds shares of the Fund as capital assets.

If you are neither a resident nor a citizen of the United States or if you are a non-U.S. entity, the Fund’s ordinary income dividends (which include distributions of net short-term capital gains) will generally be subject to a 30% U.S. withholding tax, unless a lower treaty rate applies, provided that withholding tax will generally not apply to any gain or income realized by a non-U.S. shareholder in respect of any distributions of long-term capital gains or upon the sale or other disposition of shares of the Fund.

A 30% withholding tax will be imposed on dividends paid after December 31, 2013, and redemption proceeds paid after December 31, 2014, to (i) foreign financial institutions including non-U.S. investment funds unless they agree to collect and disclose to the Internal Revenue Service (“IRS”) information regarding their direct and indirect U.S. account holders and (ii) certain other foreign entities, unless they certify certain information regarding their direct and indirect U.S. owners. To avoid withholding, foreign financial institutions will need to enter into agreements with the IRS that state that they will provide the IRS information, including the name, address and taxpayer identification number of direct and indirect U.S. account holders, comply with due diligence procedures with respect to the identification of U.S. accounts, report to the IRS certain information with respect to U.S. accounts maintained, agree to withhold tax on certain payments made to non-compliant foreign financial institutions or to account holders who fail to provide the required information, and determine certain other information as to their account holders. Other foreign entities will need to provide the name, address, and taxpayer identification number of each substantial U.S. owner or certifications of no substantial U.S. ownership unless certain exceptions apply.

Dividends, interest and capital gains received by the Fund with respect to non-U.S. securities may give rise to withholding and other taxes imposed by non-U.S. countries. Tax conventions between certain countries and the United States may reduce or eliminate such taxes.

If you are a resident or a citizen of the United States, by law, back-up withholding will apply to your distributions and proceeds if you have not provided a taxpayer identification number or social security number and made other required certifications.

Taxes When Shares are Sold. Currently, any capital gain or loss realized upon a sale of Fund shares is generally treated as a long-term gain or loss if the shares have been held for more than one year. Any capital gain or loss realized upon a sale of Fund shares held for one year or less is generally treated as short-term gain or loss, except that any capital loss on the sale of shares held for six months or less is treated as long-term capital loss to the extent that capital gain dividends were paid with respect to such shares. Beginning in 2013, any such capital gains, including from sales of Fund shares or from capital gain dividends, will be included in “net investment income” for purposes of the 3.8% U.S. federal Medicare contribution tax mentioned above.

The foregoing discussion summarizes some of the consequences under current U.S. federal tax law of an investment in the Fund. It is not a substitute for personal tax advice. You may also be subject to state and local taxation on Fund distributions and sales of shares. Consult your personal tax adviser about the potential tax consequences of an investment in shares of the Fund under all applicable tax laws.

Creations and Redemptions. Prior to trading in the secondary market, shares of the Fund are “created” at NAV by market makers, large investors and institutions only in block-size Creation Units of 50,000 shares or multiples thereof. Each “creator” or “Authorized Participant” enters into an authorized participant agreement with the Fund’s distributor, SEI Investments Distribution Co. (the “Distributor”). Only an Authorized Participant may create or redeem Creation Units directly with the Fund. A creation transaction, which is subject to acceptance by the transfer agent, generally takes place when an Authorized Participant deposits into the Fund a designated portfolio of securities and a specified amount of cash approximating the holdings of the Fund in exchange for a specified number of Creation Units. To the extent practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund.

Similarly, shares can be redeemed only in Creation Units, generally for a designated portfolio of securities and a specified amount of cash held by the Fund (“Fund Securities”). Except when aggregated in Creation Units, shares are not redeemable by the Fund. The prices at which creations and redemptions occur are based on the next calculation of NAV after an order is received in a form described in the authorized participant agreement.

The Fund intends to comply with the U.S. federal securities laws in accepting securities for deposit and satisfying redemptions with redemption securities by, among other means, assuring that any securities accepted for deposit and any securities used to satisfy redemption requests will be sold in transactions that would be exempt from registration under the Securities Act of 1933, as amended (the “1933 Act”). Further,

an Authorized Participant that is not a “qualified institutional buyer,” as such term is defined under Rule 144A of the 1933 Act, will not be able to receive Fund Securities that are restricted securities eligible for resale under Rule 144A.

Creations and redemptions must be made through a firm that is either a member of the Continuous Net Settlement System of the National Securities Clearing Corporation or a DTC participant and has executed an agreement with the Distributor with respect to creations and redemptions of Creation Unit aggregations. Information about the procedures regarding creation and redemption of Creation Units (including the cut-off times for receipt of creation and redemption orders) is included in the Fund’s SAI.

Because new shares may be created and issued on an ongoing basis, at any point during the life of the Fund a “distribution,” as such term is used in the 1933 Act, may be occurring. Broker-dealers and other persons are cautioned that some activities on their part may, depending on the circumstances, result in their being deemed participants in a distribution in a manner that could render them statutory underwriters and subject to the prospectus delivery and liability provisions of the 1933 Act. Any determination of whether one is an underwriter must take into account all the relevant facts and circumstances of each particular case.

Broker-dealers should also note that dealers who are not “underwriters” but are participating in a distribution (as contrasted to ordinary secondary transactions), and thus dealing with shares that are part of an “unsold allotment” within the meaning of Section 4(3)(C) of the 1933 Act, would be unable to take advantage of the prospectus delivery exemption provided by Section 4(3) of the 1933 Act. For delivery of prospectuses to exchange members, the prospectus delivery mechanism of Rule 153 under the 1933 Act is available only with respect to transactions on a national securities exchange.

Costs Associated with Creations and Redemptions. Authorized Participants are charged standard creation and redemption transaction fees to offset transfer and other transaction costs associated with the issuance and redemption of Creation Units. The standard creation and redemption transaction fees are set forth in the table below. The standard creation transaction fee is charged to the Authorized Participant on the day such Authorized Participant creates a Creation Unit, and is the same regardless of the number of Creation Units purchased by the Authorized Participant on the applicable business day. Similarly, the standard redemption transaction fee is charged to the Authorized Participant on the day such Authorized Participant redeems a Creation Unit, and is the same regardless of the number of Creation Units redeemed by the Authorized Participant on the applicable business day. Creations and redemptions for cash (when cash creations and redemptions (in whole or in part) are available or specified) are also subject to an additional charge (up to the maximum amounts shown in the table below). This charge is intended to compensate for brokerage, tax, foreign exchange, execution, market impact and other costs and expenses related to cash transactions. Investors who use the services of a broker or other financial intermediary may pay fees for such services.

The following table shows, as of September 30, 2011, the approximate value of one Creation Unit, standard fees and maximum additional charges for creations and redemptions (as described above):

Householding. Householding is an option available to certain Fund investors. Householding is a method of delivery, based on the preference of the individual investor, in which a single copy of certain shareholder documents can be delivered to investors who share the same address, even if their accounts are registered under different names. Please contact your broker-dealer if you are interested in enrolling in householding and receiving a single copy of prospectuses and other shareholder documents, or if you are currently enrolled in householding and wish to change your householding status.

Distribution

The Distributor distributes Creation Units for the Fund on an agency basis. The Distributor does not maintain a secondary market in shares of the Fund. The Distributor has no role in determining the policies of the Fund or the securities that are purchased or sold by the Fund. The Distributor’s principal address is One Freedom Valley Drive, Oaks, PA 19456.

In addition, BFA or its Affiliates make payments to broker-dealers, banks or other financial intermediaries (together, “intermediaries”) related to marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems, or their making shares of the Fund and certain other iShares funds available to their customers. Such payments, which may be significant to the intermediary, are not made by the Fund. Rather, such payments are made by BFA or its Affiliates from their own resources, which come directly or indirectly in part from fees paid by the iShares funds complex. Payments of this type are sometimes referred to as revenue-sharing payments. A financial intermediary may make decisions about which investment options it recommends or makes available, or the level of services provided, to its customers based on the revenue-sharing payments it is eligible to receive. Therefore, such payments to an intermediary create conflicts of interest between the intermediary and its customers and may cause the intermediary to recommend the Fund or other iShares funds over another investment. More information regarding these payments is contained in the Fund’s SAI. Please contact your salesperson or other investment professional for more information regarding any such payments his or her firm may receive from BFA or its Affiliates.

Financial Highlights

The financial highlights table is intended to help investors understand the Fund’s financial performance for the past five years. Certain information reflects financial results for a single share of the Fund. The total returns in the table represent the rate that an investor would have earned (or lost) on an investment in the Fund, assuming reinvestment of all dividends and distributions. This information has been audited by PricewaterhouseCoopers LLP, whose report is included, along with the Fund’s financial statements, in the Fund’s Annual Report (available upon request).

Supplemental Information

I. Premium/Discount Information

The table that follows presents information about the differences between the daily market price on secondary markets for shares of the Fund and the Fund’s NAV. NAV is the price at which the Fund issues and redeems shares. It is calculated in accordance with the standard formula for valuing mutual fund shares. The price used to calculate market returns (“Market Price”) of the Fund generally is determined using the midpoint between the highest bid and the lowest offer on the primary securities exchange on which shares of the Fund are listed for trading, as of the time that the Fund’s NAV is calculated. The Fund’s Market Price may be at, above or below its NAV. The NAV of the Fund will fluctuate with changes in the value of its portfolio holdings. The Market Price of the Fund will fluctuate in accordance with changes in its NAV, as well as market supply and demand.

Premiums or discounts are the differences (expressed as a percentage) between the NAV and Market Price of the Fund on a given day, generally at the time the NAV is calculated. A premium is the amount that the Fund is trading above the reported NAV, expressed as a percentage of the NAV. A discount is the amount that the Fund is trading below the reported NAV, expressed as a percentage of the NAV.

The following information shows the frequency of distributions of premiums and discounts for the Fund for each full calendar quarter of 2010 through September 30, 2011.

Each line in the table shows the number of trading days in which the Fund traded within the premium/discount range indicated. The number of trading days in each premium/discount range is also shown as a percentage of the total number of trading days in the period covered by the table. All data presented here represents past performance, which cannot be used to predict future results.

II. Total Return Information

The tables that follow present information about the total returns of the Fund and the Underlying Index as of the fiscal year ended July 31, 2011.

“Average Annual Total Returns” represent the average annual change in value of an investment over the periods indicated. “Cumulative Total Returns” represent the total change in value of an investment over the periods indicated.

The Fund’s NAV is the value of one share of the Fund as calculated in accordance with the standard formula for valuing mutual fund shares. The NAV return is based on the NAV of the Fund and the market return is based on the Market Price of the Fund. Market Price is determined by using the midpoint between the highest bid and the lowest offer on the primary stock exchange on which shares of the Fund are listed for trading, as of the time that the Fund’s NAV is calculated. Market and NAV returns assume that dividends and capital gain distributions have been reinvested in the Fund at Market Price and NAV, respectively.

An index is a statistical composite that tracks a specified financial market or sector. Unlike the Fund, the Underlying Index does not actually hold a portfolio of securities and therefore does not incur the expenses incurred by the Fund. These expenses negatively impact the performance of the Fund. Also, market returns do not include brokerage commissions that may be payable on secondary market transactions. If brokerage commissions were included, market returns would be lower. The returns shown in the following tables do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption or sale of Fund shares. The investment return and principal value of shares of the Fund will vary with changes in market conditions. Shares of the Fund may be worth more or less than their original cost when they are redeemed or sold in the market. The Fund’s past performance is no guarantee of future results.

Fund Overview

iSHARES® S&P NORTH AMERICAN NATURAL RESOURCES SECTOR INDEX FUND

Ticker: IGE Stock Exchange: NYSE Arca

Investment Objective

The iShares S&P North American Natural Resources Sector Index FundTM (the “Fund”) seeks investment results that correspond generally to the price and yield performance, before fees and expenses, of the S&P North American Natural Resources Sector IndexTM (the “Underlying Index”).

Fees and Expenses

The following table describes the fees and expenses that you will incur if you own shares of the Fund. The investment advisory agreement between iShares Trust (the “Trust”) and BlackRock Fund Advisors (“BFA”) (the “Investment Advisory Agreement”) provides that BFA will pay all operating expenses of the Fund, except interest expenses, taxes, brokerage expenses, future distribution fees or expenses, and extraordinary expenses.

You may also incur usual and customary brokerage commissions when buying or selling shares of the Fund, which are not reflected in the example that follows:

Example. This Example is intended to help you compare the cost of owning shares of the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

Portfolio Turnover. The Fund may pay transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 11% of the average value of its portfolio.

Principal Investment Strategies

The Underlying Index measures the performance of U.S.-traded stocks of natural resource-related companies in the U.S. and Canada. The Underlying Index includes companies in the following categories: producers of oil, gas and consumable fuels, energy equipment and services, metals and mining, manufacturers of paper and forest products, and producers of construction materials, containers and packaging.

BFA uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to “beat” the index it tracks and does not seek temporary defensive positions when markets decline or appear overvalued.

Indexing may eliminate the chance that the Fund will substantially outperform the Underlying Index but also may reduce some of the risks of active management, such as poor security selection. Indexing seeks to achieve lower costs and better after-tax performance by keeping portfolio turnover low in comparison to actively managed investment companies.

BFA uses a representative sampling indexing strategy to manage the Fund. “Representative sampling” is an indexing strategy that involves investing in a representative sample of securities that collectively has an investment profile similar to the Underlying Index. The securities selected are expected to have, in the aggregate, investment characteristics (based on factors such as market capitalization and industry weightings), fundamental characteristics (such as return variability and yield) and liquidity measures similar to those of the Underlying Index. The Fund may or may not hold all of the securities in the Underlying Index.

The Fund generally invests at least 90% of its assets in securities of the Underlying Index and in depositary receipts representing securities of the Underlying Index. The Fund may invest the remainder of its assets in securities not included in the Underlying Index, but which BFA believes will help the Fund track the Underlying Index and in other investments including futures contracts, options on futures contracts, options and swaps as well as cash and cash equivalents, including shares of money market funds advised by BFA or its affiliates.

The Fund may lend securities representing up to one-third of the value of the Fund’s total assets (including the value of the collateral received).

The Underlying Index is sponsored by an organization (the “Index Provider”) that is independent of the Fund and BFA. The Index Provider determines the

S-2   


Table Of Contents



composition and relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index. The Fund’s Index Provider is Standard & Poor’s Financial Services LLC (a subsidiary of The McGraw-Hill Companies) (“S&P”).

Industry Concentration Policy. The Fund will concentrate its investments (i.e., hold 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. For purposes of this limitation, securities of the U.S. government (including its agencies and instrumentalities) and repurchase agreements collateralized by U.S. government securities are not considered to be issued by members of any industry.

Summary of Principal Risks

As with any investment, you could lose all or part of your investment in the Fund, and the Fund’s performance could trail that of other investments. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund’s net asset value per share (“NAV”), trading price, yield, total return and ability to meet its investment objective.

Asset Class Risk. Securities in the Underlying Index or in the Fund’s portfolio may underperform in comparison to the general securities markets or other asset classes.

Concentration Risk. To the extent that the Fund’s investments are concentrated in a particular issuer, region, country, market, industry or asset class, the Fund may be susceptible to loss due to adverse occurrences affecting that issuer, region, country, market, industry or asset class.

Energy Sector Risk. The value of securities issued by companies in the energy sector may decline for many reasons, including, without limitation, changes in commodity prices, government regulations, energy conservation efforts and potential civil liabilities.

Equity Securities Risk. Equity securities are subject to changes in value and their values may be more volatile than other asset classes.

Issuer Risk. Fund performance depends on the performance of individual securities to which the Fund has exposure. Changes to the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA’s investment management strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares, losses from trading in secondary markets, periods of high volatility and disruption in the creation/redemption process of the Fund. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV.

Metals and Mining Sector Risk. Companies in the metals and mining sector are susceptible to fluctuations in worldwide metal prices, and exploration and production costs. In addition, metals and mining companies may have significant operations in areas at risk for social and political unrest, security concerns and environmental damage. These companies may also be at risk for increased government regulation and intervention. As a result, such risks may adversely affect the issuers to which the Fund has exposure.

Natural Resources Sector Risk. The value of securities issued by companies in the natural resources sector may decline for many reasons including changes in commodity prices, government regulation, environmental damage claims, changes in exchange rates or depletion of natural resources.

Non-Diversification Risk. The Fund may invest a large percentage of its assets in securities issued by or representing a small number of issuers. As a result, the Fund’s performance may depend on the performance of a small number of issuers.

Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers are subject to the risks associated with investing in those non-U.S. markets, such as heightened risks of inflation or nationalization. The Fund may lose money due to political, economic and geographic events affecting a non-U.S. issuer or market.

Oil and Gas Sector Risk. Companies in the oil and gas sector are affected by worldwide energy prices, exploration and production costs. Companies in the oil and gas sector may have significant operations in areas at risk for natural disasters, social unrest and environmental damage. These companies may also be at risk for increased government regulation and intervention, litigation, and negative publicity and perception.

Passive Investment Risk. The Fund is not actively managed and BFA does not attempt to take defensive positions under any market conditions, including declining markets.

Risk of Investing in Canada. The Fund’s investment in Canadian issuers may subject the Fund to economic risk specific to Canada. Among other things, the Canadian economy is heavily dependent on relationships with certain key trading partners, including the United States, European Union countries and China. As a result, the Canadian economy is significantly affected by developments in the economies of these countries.

Securities Lending Risk. The Fund may engage in securities lending. Securities lending involves the risk that the Fund may lose money because the borrower of the Fund’s loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Tracking Error Risk. The performance of the Fund may diverge from that of the Underlying Index. Because the Fund employs a representative sampling strategy, the Fund may experience tracking error to a greater extent than a fund that seeks to replicate an index.

1 After-tax returns in the table above are calculated using the historical highest individual U.S. federal marginal income tax rates and do not reflect the impact of state or local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown, and after-tax returns shown are not relevant to tax-exempt investors or investors who hold shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts (“IRAs”). Fund returns after taxes on distributions and sale of Fund shares are calculated assuming that an investor has sufficient capital gains of the same character from other investments to offset any capital losses from the sale of Fund shares. As a result, Fund returns after taxes on distributions and sale of Fund shares may exceed Fund returns before taxes and/or returns after taxes on distributions.

Management

Investment Adviser. BlackRock Fund Advisors.

Portfolio Managers. Rene Casis, Diane Hsiung and Greg Savage (the “Portfolio Managers”) are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager supervises a portfolio management team. Mr. Casis, Ms. Hsiung and Mr. Savage have been Portfolio Managers of the Fund since 2010, 2008 and 2008, respectively.

Purchase and Sale of Fund Shares

The Fund is an exchange-traded fund (commonly referred to as an “ETF”). Individual Fund shares may only be purchased and sold on a national securities exchange through a broker-dealer. The price of Fund shares is based on market price, and because ETF shares trade at market prices rather than NAV, shares may trade at a price greater than NAV (a premium) or less than NAV (a discount). The Fund will only issue or redeem shares that have been aggregated into blocks of 50,000 shares or multiples thereof (“Creation Units”) to authorized participants who have entered into agreements with the Fund’s distributor. The Fund generally will issue or redeem Creation Units in return for a designated portfolio of securities (and an amount of cash) that the Fund specifies each day.

Tax Information

The Fund intends to make distributions that may be taxable to you as ordinary income or capital gains, unless you are investing through a tax-deferred arrangement such as a 401(k) plan or an IRA.

Payments to Broker-Dealers and other Financial Intermediaries

If you purchase shares of the Fund through a broker-dealer or other financial intermediary (such as a bank), BFA or other related companies may pay the intermediary for marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems or other services related to the sale or promotion of the Fund. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.

More Information About the Fund

This Prospectus contains important information about investing in the Fund. Please read this Prospectus carefully before you make any investment decisions. Additional information regarding the Fund is available at www.iShares.com.

BFA is the investment adviser to the Fund. Shares of the Fund are listed for trading on NYSE Arca, Inc. (“NYSE Arca”). The market price for a share of the Fund may be different from the Fund’s most recent NAV.

ETFs are funds that trade like other publicly-traded securities. The Fund is designed to track an index. Similar to shares of an index mutual fund, each share of the Fund represents a partial ownership in an underlying portfolio of securities intended to track a market index. Unlike shares of a mutual fund, which can be bought and redeemed from the issuing fund by all shareholders at a price based on NAV, shares of the Fund may be purchased or redeemed directly from the Fund at NAV solely by authorized participants. Also unlike shares of a mutual fund, shares of the Fund are listed on a national securities exchange and trade in the secondary market at market prices that change throughout the day.

The Fund invests in a particular segment of the securities markets and seeks to track the performance of a securities index that generally is not representative of the market as a whole. The Fund is designed to be used as part of broader asset allocation strategies. Accordingly, an investment in the Fund should not constitute a complete investment program.

An index is a theoretical financial calculation while the Fund is an actual investment portfolio. The performance of the Fund and the Underlying Index may vary due to transaction costs, non-U.S. currency valuations, asset valuations, corporate actions (such as mergers and spin-offs), timing variances and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions (such as diversification requirements) that apply to the Fund but not to the Underlying Index or to the use of representative sampling. “Tracking error” is the difference between the performance (return) of the Fund’s portfolio and that of the Underlying Index. BFA expects that, over time, the Fund’s tracking error will not exceed 5%. Because the Fund uses a representative sampling indexing strategy, it can be expected to have a larger tracking error than if it used a replication indexing strategy. “Replication” is an indexing strategy in which a fund invests in substantially all of the securities in its underlying index in approximately the same proportions as in the underlying index.

An investment in the Fund is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, BFA or any of its affiliates.

The Fund’s investment objective and the Underlying Index may be changed without shareholder approval.

A Further Discussion of Principal Risks

The Fund is subject to various risks, including the principal risks noted below, any of which may adversely affect the Fund’s NAV, trading price, yield, total return and ability to meet its investment objective. You could lose all or part of your investment in the Fund, and the Fund could underperform other investments.

Asset Class Risk. The securities in the Underlying Index or in the Fund’s portfolio may underperform the returns of other securities or indexes that track other industries, groups of industries, markets, asset classes or sectors. Various types of securities or indexes tend to experience cycles of outperformance and underperformance in comparison to the general securities markets.

Concentration Risk. To the extent that the Fund’s portfolio reflects the Underlying Index’s concentration in the securities of a particular issuer or issuers in a particular country, group of countries, region, market, industry, group of industries, sector or asset class, the Fund may be adversely affected by the performance of those securities, may be subject to increased price volatility and may be more susceptible to adverse economic, market, political or regulatory occurrences affecting that issuer, country, group of countries, region, market, industry, group of industries, sector or asset class.

Energy Sector Risk. The energy sector is cyclical and highly dependent on commodities prices. The market values of companies in the energy sector are strongly affected by the levels and volatility of global energy prices, energy supply and demand, capital expenditures on exploration and production, energy conservation efforts, exchange rates and technological advances, among other factors. Companies in this sector may be subject to substantial government regulation and contractual fixed pricing, which may increase the cost of business and limit these companies’ earnings. A significant portion of their revenues depends on a relatively small number of customers, including governmental entities and utilities. As a result, governmental budget constraints may have a material adverse effect on the stock prices of companies in this industry. Energy companies may also operate in countries with less developed regulatory regimes or a history of expropriation, nationalization or other adverse policies. Energy companies also face a significant risk of civil liability from accidents resulting in injury or loss of life or property, pollution or other environmental mishaps, equipment malfunctions or mishandling of materials and a risk of loss from terrorism and natural disasters. Any such event could have serious consequences for the general population of the area affected and result in a material adverse impact on the Fund’s portfolio and the performance of the Fund. Energy companies can be significantly affected by the supply of, and demand for, specific products (e.g., oil and natural gas) and services, exploration and production spending, government regulation, world events and general economic conditions.

Equity Securities Risk. The Fund invests in equity securities, which are subject to changes in value that may be attributable to market perception of a particular issuer or to general stock market fluctuations that affect all issuers. Investments in equity securities may be more volatile than investments in other asset classes.

Issuer Risk. The performance of the Fund depends on the performance of individual securities to which the Fund has exposure. Any issuer of these securities may perform poorly, causing the value of its securities to decline. Poor performance may be caused by poor management decisions, competitive pressures, changes in technology, expiration of patent protection, disruptions in supply, labor problems or shortages, corporate restructurings, fraudulent disclosures or other factors. Issuers may, in times of distress or at their own discretion, decide to reduce or eliminate dividends, which may also cause their stock prices to decline.

Management Risk. The Fund may not fully replicate the Underlying Index and may hold securities not included in the Underlying Index. As a result, the Fund is subject to the risk that BFA’s investment management strategy, the implementation of which is subject to a number of constraints, may not produce the intended results.

Market Risk. The Fund could lose money due to short-term market movements and over longer periods during market downturns. Securities may decline in value due to factors affecting securities markets generally or particular industries represented in the markets. The value of a security may decline due to general market conditions, economic trends or events that are not specifically related to the issuer of the security or to factors that affect a particular industry or industries. During a general downturn in the securities markets, multiple asset classes may be negatively affected.

Market Trading Risk

Absence of Active Market. Although shares of the Fund are listed for trading on one or more stock exchanges, there can be no assurance that an active trading market for such shares will develop or be maintained.

Risk of Secondary Listings. The Fund’s shares may be listed or traded on U.S. and non-U.S. stock exchanges other than the U.S. stock exchange where the Fund’s primary listing is maintained. There can be no assurance that the Fund’s shares will continue to trade on any such stock exchange or in any market or that the Fund’s shares will continue to meet the requirements for listing or trading on any exchange or in any market. The Fund’s shares may be less actively traded in certain markets than others, and investors are subject to the execution and settlement risks and market standards of the market where they or their broker direct their trades for execution. Certain information available to investors who trade Fund shares on a U.S. stock exchange during regular U.S. market hours may not be available to investors who trade in other markets, which may result in secondary market prices in such markets being less efficient.

Secondary Market Trading Risk. Shares of the Fund may trade in the secondary market at times when the Fund does not accept orders to purchase or redeem shares. At such times, shares may trade in the secondary market with more significant premiums or discounts than might be experienced at times when the Fund accepts purchase and redemption orders.

Secondary market trading in Fund shares may be halted by a stock exchange because of market conditions or other reasons. In addition, trading in Fund shares on a stock exchange or in any market may be subject to trading halts caused by extraordinary market volatility pursuant to “circuit breaker” rules on the stock exchange or market.

There can be no assurance that the requirements necessary to maintain the listing or trading of Fund shares will continue to be met or will remain unchanged.

Shares of the Fund May Trade at Prices Other Than NAV. Shares of the Fund trade on stock exchanges at prices at, above or below their most recent NAV. The NAV of the Fund is calculated at the end of each business day and fluctuates with changes in the market value of the Fund’s holdings since the most recent calculation. The trading prices of the Fund’s shares fluctuate continuously throughout trading hours based on market supply and demand rather than NAV. The trading prices of the Fund’s shares may deviate significantly from NAV during periods of market volatility. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV. However, because shares can be created and redeemed in Creation Units at NAV (unlike shares of many closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their NAVs), BFA believes that large discounts or premiums to the NAV of the Fund are not likely to be sustained over the long-term. While the creation/redemption feature is designed to make it likely that the Fund’s shares normally will trade on stock exchanges at prices close to the Fund’s next calculated NAV, exchange prices are not expected to correlate exactly with the Fund’s NAV due to timing reasons as well as market supply and demand factors. In addition, disruptions to creations and redemptions or extreme market volatility may result in trading prices for shares of the Fund that differ significantly from its NAV.

Costs of Buying or Selling Fund Shares. Buying or selling Fund shares on an exchange involves two types of costs that apply to all securities transactions. When buying or selling shares of the Fund through a broker, you will likely incur a brokerage commission or other charges imposed by brokers as determined by that broker. In addition, you may incur the cost of the “spread” – that is, the difference between what investors are willing to pay for Fund shares (the “bid” price) and the price at which they are willing to sell Fund shares (the “ask” price). Because of the costs inherent in buying or selling Fund shares, frequent trading may detract significantly from investment results and an investment in Fund shares may not be advisable for investors who anticipate regularly making small investments.

Metals and Mining Sector Risk. The Fund will invest in securities that are issued by and/or have exposure to, companies primarily involved in the metals and mining sector. Investments in metals and mining sector companies may be speculative and subject to greater price volatility than investments in other types of companies. The profitability of companies in the metals and mining sector is related to, among other things, worldwide metal prices, and exploration and production costs. Worldwide metal prices may fluctuate substantially over short periods of time, so the Fund’s share price may be more volatile than other types of investments. In addition, metals and mining companies may be significantly affected by changes in global demand for certain metals, economic developments, energy conservation, exchange rates, the success of exploration projects, interest rates, economic conditions, tax treatment, government regulation and intervention, and world events in the regions that the companies to which the Fund has exposure operate (e.g., expropriation, nationalization, confiscation of assets and property or the imposition of restrictions on foreign investments and

repatriation of capital, military coups, social unrest, violence and labor unrest). Metals and mining companies may also be subject to the effects of competitive pressures in the metals and mining sector.

Natural Resources Sector Risk. The profitability of companies in the natural resources sector can be affected by worldwide energy prices, limits on exploration, and production spending. Companies in the natural resources sector are affected by government regulation, world events and economic conditions. Companies in the natural resources sector are at risk for environmental damage claims. Companies in the natural resources sector could be adversely affected by commodity price volatility, changes in exchange rates, imposition of import controls and increased competition. Companies in the natural resources sector may be adversely affected by depletion of natural resources, technological developments, and labor relations.

Non-Diversification Risk. The Fund is classified as “non-diversified.” This means that the Fund may invest a large percentage of its assets in securities issued by or representing a small number of issuers. As a result, the Fund may be more susceptible to the risks associated with these particular issuers, or to a single economic, political or regulatory occurrence affecting these issuers.

Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers are subject to all of the risks of investing in the markets where such issuers are located, including heightened risks of inflation or nationalization and market fluctuations caused by economic and political developments. As a result of investing in non-U.S. securities, the Fund may be subject to increased risk of loss caused by any of the factors listed below:

  • Lower levels of liquidity and market efficiency;
  • Greater securities price volatility;
  • Exchange rate fluctuations and exchange controls;
  • Less availability of public information about issuers;
  • Limitations on foreign ownership of securities;
  • Imposition of withholding or other taxes;
  • Imposition of restrictions on the expatriation of the funds or other assets of the Fund;
  • Higher transaction and custody costs and delays in settlement procedures;
  • Difficulties in enforcing contractual obligations;
  • Lower levels of regulation of the securities market;
  • Weaker accounting, disclosure and reporting requirements; and
  • Legal principles related to corporate governance, directors’ fiduciary duties and liabilities and stockholders’ rights in markets in which the Fund invests may differ and/or may not be as extensive or protective as those that apply in the United States.

Oil and Gas Sector Risk. The profitability of companies in the oil and gas sector is related to worldwide energy prices, exploration, and production spending. Companies in the oil and gas sector may be adversely affected by natural disasters or other

catastrophes. Companies in the oil and gas sector may be at risk for environmental damage claims and other types of litigation. Companies in the oil and gas sector may be adversely affected by changes in exchange rates, interest rates, changes in prices for competitive energy services, economic conditions, tax treatment, government regulation and intervention, negative perception and world events in the regions where companies operate (e.g., expropriation, nationalization, confiscation of assets and property or imposition of restrictions on foreign investments and repatriation of capital, military coups, social unrest, violence or labor unrest). Companies in the oil and gas sector may have significant capital investments in, or engage in transactions involving, emerging market countries, which may heighten these risks.

Passive Investment Risk. The Fund is not actively managed and may be affected by a general decline in market segments related to the Underlying Index. The Fund invests in securities included in, or representative of, the Underlying Index regardless of their investment merits. BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

Risk of Investing in Canada. The United States is Canada’s largest trading and investment partner, and the Canadian economy is significantly affected by developments in the U.S. economy. Since the implementation of the North American Free Trade Agreement (“NAFTA”) in 1994 among Canada, the United States and Mexico, total two-way merchandise trade between the United States and Canada has more than doubled. To further this relationship, the three NAFTA countries entered into the Security and Prosperity Partnership of North America in March 2005, which may further affect Canada’s dependency on the U.S. economy. Any downturn in U.S. or Mexican economic activity is likely to have an adverse impact on the Canadian economy. The Canadian economy is also dependent upon external trade with other key trading partners, specifically China and the United Kingdom. As a result, Canada is dependent on the economies of these other countries. In addition, Canada is a large supplier of natural resources (e.g., oil, natural gas and agricultural products). As a result, the Canadian economy is sensitive to fluctuations in certain commodity prices.

Securities Lending Risk. The Fund may engage in securities lending. Securities lending involves the risk that the Fund may lose money because the borrower of the Fund’s loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for the loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Tracking Error Risk. Imperfect correlation between the Fund’s portfolio securities and those in the Underlying Index, rounding of prices, changes to the Underlying Index and regulatory requirements may cause tracking error, which is the divergence of the Fund’s performance from that of the Underlying Index. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Underlying Index does not. Because the Fund employs a representative sampling strategy, the Fund may experience tracking error to a greater extent than a fund that seeks to replicate an index.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

European Economic Risk. The Economic and Monetary Union (the “EMU”) of the European Union (the “EU”) requires member countries to comply with restrictions on inflation rates, deficits, interest rates, debt levels and fiscal and monetary controls, each of which may significantly affect every country in Europe. Decreasing imports or exports, changes in governmental or EU regulations on trade, changes in the exchange rate of the euro, the default or threat of default by an EU member country on its sovereign debt, and/or an economic recession in an EU member country may have a significant adverse effect on the economies of EU member countries and their trading partners. The European financial markets have recently experienced volatility and have been adversely affected by concerns about economic downturns, credit rating downgrades, rising government debt levels and possible default on or restructuring of government debt in several European countries, including Greece, Ireland, Italy, Portugal and Spain. A default or debt restructuring by any European country would adversely impact holders of that country’s debt, and sellers of credit default swaps linked to that country’s creditworthiness, which may be located in countries other than those listed in the previous sentence. These events have adversely affected the value and exchange rate of the euro and may continue to significantly affect the economies of every country in Europe, including EU member countries that do not use the euro and non-EU member countries.

Portfolio Holdings Information

A description of the Trust’s policies and procedures with respect to the disclosure of the Fund’s portfolio securities is available in the Fund’s Statement of Additional Information (“SAI”). The top holdings of the Fund can be found at www.iShares.com. Fund fact sheets provide information regarding the Fund’s top holdings and may be requested by calling 1-800-iShares (1-800-474-2737).

Management

Investment Adviser. As investment adviser, BFA has overall responsibility for the general management and administration of the Trust. BFA provides an investment program for the Fund and manages the investment of the Fund’s assets. In managing the Fund, BFA may draw upon the research and expertise of its asset management affiliates with respect to certain portfolio securities. In seeking to achieve the Fund’s investment objective, BFA uses teams of portfolio managers, investment strategists and other investment specialists. This team approach brings together many disciplines and leverages BFA’s extensive resources.

Pursuant to the Investment Advisory Agreement between BFA and the Trust (entered into on behalf of the Fund), BFA is responsible for substantially all expenses of the Fund, except interest expenses, taxes, brokerage expenses, future distribution fees or expenses and extraordinary expenses.

For its investment advisory services to the Fund, BFA is entitled to receive a management fee from the Fund corresponding to the Fund’s allocable portion of an aggregate management fee based on the aggregate average daily net assets of the following iShares funds: iShares PHLX SOX Semiconductor Sector Index Fund, iShares S&P Global Clean Energy Index Fund, iShares S&P Global Consumer Discretionary Sector Index Fund, iShares S&P Global Consumer Staples Sector Index Fund, iShares S&P Global Energy Sector Index Fund, iShares S&P Global Financials Sector Index Fund, iShares S&P Global Healthcare Sector Index Fund, iShares S&P Global Industrials Sector Index Fund, iShares S&P Global Infrastructure Index Fund, iShares S&P Global Materials Sector Index Fund, iShares S&P Global Nuclear Energy Index Fund, iShares S&P Global Technology Sector Index Fund, iShares S&P Global Telecommunications Sector Index Fund, iShares S&P Global Timber & Forestry Index Fund, iShares S&P Global Utilities Sector Index Fund, iShares S&P North American Natural Resources Sector Index Fund, iShares S&P North American Technology Sector Index Fund, iShares S&P North American Technology-Multimedia Networking Index Fund and iShares S&P North American Technology-Software Index Fund. The aggregate management fee is calculated as follows: 0.48% per annum of the aggregate net assets less than or equal to $10.0 billion, plus 0.43% per annum of the aggregate net assets over $10.0 billion, up to and including $20.0 billion, plus 0.38% per annum of the aggregate net assets in excess of $20.0 billion. As calculated on July 31, 2011, for its investment advisory services to the Fund, BFA is entitled to receive a management fee from the Fund, based on a percentage of the Fund’s average daily net assets, at an annual rate of 0.48%.

BFA is located at 400 Howard Street, San Francisco, CA 94105. It is a wholly owned subsidiary of BTC, which in turn is indirectly wholly-owned by BlackRock, Inc. (“BlackRock”). As of September 30, 2011, BTC and its affiliates, including BFA and BlackRock, provided investment advisory services for assets in excess of $3.35 trillion. BFA, BTC, BlackRock Execution Services, BlackRock and their affiliates deal, trade and invest for their own accounts in the types of securities in which the Fund may also invest.

A discussion regarding the basis for the Trust’s Board of Trustees’ (the “Board”) approval of the Investment Advisory Agreement with BFA is available in the Fund’s annual report for the period ended July 31.

Portfolio Managers. Rene Casis, Diane Hsiung and Greg Savage are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager is responsible for various functions related to portfolio management, including, but not limited to, investing cash inflows, coordinating with members of his or her portfolio management team to focus on certain asset classes, implementing investment strategy, researching and reviewing investment strategy and overseeing members of his or her portfolio management team that have more limited responsibilities.

Rene Casis has been employed by BFA (formerly, Barclays Global Fund Advisors (“BGFA”)) and BTC (formerly, Barclays Global Investors, N.A. (“BGI”)) as a senior portfolio manager since 2009. From 2005 to 2009, Mr. Casis was a trader at Barclays Capital. Prior to that, Mr. Casis was a portfolio manager from 2000 to 2005 for BGFA and BGI. Mr. Casis has been a Portfolio Manager of the Fund since 2010.

Diane Hsiung has been employed by BFA and BTC as a senior portfolio manager since 2007. Prior to that, Ms. Hsiung was a portfolio manager from 2002 to 2006 for BGFA and BGI. Ms. Hsiung has been a Portfolio Manager of the Fund since 2008.

Greg Savage has been employed by BFA and BTC as a senior portfolio manager since 2006. Prior to that, Mr. Savage was a portfolio manager from 2001 to 2006 for BGFA and BGI. Mr. Savage has been a Portfolio Manager of the Fund since 2008.

The Fund’s SAI provides additional information about the Portfolio Managers’ compensation, other accounts managed by the Portfolio Managers and the Portfolio Managers’ ownership (if any) of shares in the Fund.

Administrator, Custodian and Transfer Agent. State Street Bank and Trust Company (“State Street”) is the administrator, custodian and transfer agent for the Fund.

Conflicts of Interest. BFA wants you to know that there are certain entities with which BFA has relationships that may give rise to conflicts of interest, or the appearance of conflicts of interest. These entities include the following: BFA’s affiliates (including BlackRock and The PNC Financial Services Group, Inc., and each of their affiliates, directors, partners, trustees, managing members, officers and employees (collectively, the “Affiliates”)) and BlackRock’s significant shareholder, Barclays Bank PLC and its affiliates, including Barclays PLC (each, an “Entity” and together, the “Entities”).

The activities of BFA, the Affiliates and the Entities in the management of, or their interest in, their own accounts and other accounts they manage, may present conflicts of interest that could disadvantage the Fund and its shareholders. BFA and its Affiliates or the Entities provide investment management services to other funds and discretionary managed accounts that may follow an investment program similar to that of the Fund. BFA, its Affiliates and the Entities are involved worldwide with a broad spectrum of financial services and asset management activities and may engage in the ordinary course of business in activities in which their interests or the interests of their clients may conflict with those of the Fund. BFA, one or more of the Affiliates or the Entities acts, or may act, as an investor, investment banker, research provider, investment manager, financier, underwriter, advisor, market maker, trader, prime broker, lender, agent or principal, and have other direct and indirect interests, in securities, currencies and other instruments in which the Fund may directly or indirectly invest. Thus, it is likely that the Fund will have multiple business relationships with and will invest in, engage in transactions with, make voting decisions with respect to, or obtain services from, entities for which BFA, an Affiliate or an Entity performs or seeks to perform investment banking or other services.

BFA or one or more Affiliates or Entities may engage in proprietary trading and advise accounts and funds that have investment objectives similar to those of the Fund and/or that engage in and compete for transactions in the same types of securities, currencies and other instruments as the Fund, including in securities issued by other open-end and closed-end investment management companies, including investment companies that are affiliated with the Fund and BFA, to the extent permitted under the Investment Company Act of 1940, as amended (the “1940 Act”). The trading activities

of BFA, these Affiliates and Entities are carried out without reference to positions held directly or indirectly by the Fund and may result in BFA, an Affiliate or an Entity having positions that are adverse to those of the Fund.

No Affiliate or Entity is under any obligation to share any investment opportunity, idea or strategy with the Fund. As a result, an Affiliate or an Entity may compete with the Fund for appropriate investment opportunities. As a result of this and several other factors, the results of the Fund’s investment activities may differ from those of an Affiliate or an Entity and of other accounts managed by an Affiliate or an Entity, and it is possible that the Fund could sustain losses during periods in which one or more Affiliates or Entities and other accounts achieve profits on their trading for proprietary or other accounts. The opposite result is also possible.

The Fund may, from time to time, enter into transactions in which BFA or an Affiliate’s or an Entity’s clients have an interest adverse to the Fund. Furthermore, transactions undertaken by Affiliate-advised clients may adversely impact the Fund. Transactions by one or more Affiliate- or Entity-advised clients or BFA may have the effect of diluting or otherwise disadvantaging the values, prices or investment strategies of the Fund.

An Entity may maintain securities indices as part of its product offerings. Index-based funds seek to track the performance of securities indices and may use the name of the index in the fund name. Index providers, including the Entities, may be paid licensing fees for use of their indices or index names. Entities will not be obligated to license their indices to BFA and its Affiliates, and BFA and its Affiliates will not be assured that the terms of any index licensing agreement with the Entities will be as favorable as those terms offered to other index licensees.

The Fund’s activities may be limited because of regulatory restrictions applicable to one or more Affiliates or Entities, and/or their internal policies designed to comply with such restrictions. In addition, the Fund may invest in securities of companies with which an Affiliate or an Entity has or is trying to develop investment banking relationships or in which an Affiliate or an Entity has significant debt or equity investments. The Fund also may invest in securities of companies for which an Affiliate or an Entity provides or may some day provide research coverage. An Affiliate or an Entity may have business relationships with and purchase or distribute or sell services or products from or to distributors, consultants or others who recommend the Fund or who engage in transactions with or for the Fund, and may receive compensation for such services. The Fund may also make brokerage and other payments to Affiliates or Entities in connection with the Fund’s portfolio investment transactions.

Pursuant to a securities lending program approved by the Board, the Fund has retained an Affiliate of BFA to serve as the securities lending agent for the Fund to the extent that the Fund participates in the securities lending program. For these services, the lending agent may receive a fee from the Fund, including a fee based on the returns earned on the Fund’s investment of the cash received as collateral for any loaned securities. In addition, one or more Affiliates may be among the entities to which the Fund may lend its portfolio securities under the securities lending program.

The activities of BFA, the Affiliates or Entities may give rise to other conflicts of interest that could disadvantage the Fund and its shareholders. BFA has adopted policies and

procedures designed to address these potential conflicts of interest. See the Fund’s SAI for further information.

Shareholder Information

Buying and Selling Shares. Shares of the Fund may be acquired or redeemed directly from the Fund only in Creation Units or multiples thereof, as discussed in the Creations and Redemptions section of this Prospectus. Only an Authorized Participant (as defined in the Creations and Redemptions section) may engage in creation or redemption transactions directly with the Fund. Once created, shares of the Fund generally trade in the secondary market in amounts less than a Creation Unit.

Shares of the Fund are listed on a national securities exchange for trading during the trading day. Shares can be bought and sold throughout the trading day like shares of other publicly-traded companies. The Trust does not impose any minimum investment for shares of the Fund purchased on an exchange. The Fund’s shares trade under the trading symbol “IGE.”

Buying or selling Fund shares on an exchange involves two types of costs that may apply to all securities transactions. When buying or selling shares of the Fund through a broker, you will likely incur a brokerage commission or other charges determined by your broker. The commission is frequently a fixed amount and may be a significant proportional cost for investors seeking to buy or sell small amounts of shares. In addition, you may incur the cost of the “spread” – that is, any difference between the bid price and the ask price. The spread varies over time for shares of the Fund based on its trading volume and market liquidity, and is generally lower if the Fund has a lot of trading volume and market liquidity, and higher if the Fund has little trading volume and market liquidity.

The Board has adopted a policy of not monitoring for frequent purchases and redemptions of Fund shares (“frequent trading”) that appear to attempt to take advantage of a potential arbitrage opportunity presented by a lag between a change in the value of the Fund’s portfolio securities after the close of the primary markets for the Fund’s portfolio securities and the reflection of that change in the Fund’s NAV (“market timing”), because the Fund generally sells and redeems its shares directly through transactions that are in-kind and/or for cash, subject to the conditions described below under Creations and Redemptions. The Board has not adopted a policy of monitoring for other frequent trading activity because shares of the Fund are listed for trading on a national securities exchange.

The national securities exchange on which the Fund’s shares are listed is open for trading Monday through Friday and is closed on weekends and the following holidays: New Year’s Day, Martin Luther King, Jr. Day, Presidents’ Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day. The Fund’s primary listing exchange is NYSE Arca.

Section 12(d)(1) of the 1940 Act restricts investments by investment companies in the securities of other investment companies. Registered investment companies are permitted to invest in the Fund beyond the limits set forth in Section 12(d)(1), subject to certain terms and conditions set forth in SEC rules or in an SEC exemptive order issued to the Trust. In order for a registered investment company to invest in shares of the Fund beyond the limitations of Section 12(d)(1) pursuant to the exemptive relief obtained by the Trust, the registered investment company must enter into an agreement with the Trust.

Book Entry. Shares of the Fund are held in book-entry form, which means that no stock certificates are issued. The Depository Trust Company (“DTC”) or its nominee is the record owner of all outstanding shares of the Fund and is recognized as the owner of all shares for all purposes.

Investors owning shares of the Fund are beneficial owners as shown on the records of DTC or its participants. DTC serves as the securities depository for shares of the Fund. DTC participants include securities brokers and dealers, banks, trust companies, clearing corporations and other institutions that directly or indirectly maintain a custodial relationship with DTC. As a beneficial owner of shares, you are not entitled to receive physical delivery of stock certificates or to have shares registered in your name, and you are not considered a registered owner of shares. Therefore, to exercise any right as an owner of shares, you must rely upon the procedures of DTC and its participants. These procedures are the same as those that apply to any other securities that you hold in book-entry or “street name” form.

Share Prices. The trading prices of the Fund’s shares in the secondary market generally differ from the Fund’s daily NAV and are affected by market forces such as supply and demand, economic conditions and other factors. Information regarding the intraday value of shares of the Fund, also known as the “indicative optimized portfolio value” (“IOPV”), is disseminated every 15 seconds throughout the trading day by the national securities exchange on which the Fund’s shares are listed or by market data vendors or other information providers. The IOPV is based on the current market value of the securities and/or cash required to be deposited in exchange for a Creation Unit. The IOPV does not necessarily reflect the precise composition of the current portfolio of securities held by the Fund at a particular point in time or the best possible valuation of the current portfolio. Therefore, the IOPV should not be viewed as a “real-time” update of the Fund’s NAV, which is computed only once a day. The IOPV is generally determined by using both current market quotations and/or price quotations obtained from broker-dealers that may trade in the portfolio securities held by the Fund. The quotations of certain Fund holdings may not be updated during U.S. trading hours if such holdings do not trade in the United States. The Fund is not involved in, or responsible for, the calculation or dissemination of the IOPV and makes no representation or warranty as to its accuracy.

Determination of Net Asset Value. The NAV of the Fund normally is determined once daily Monday through Friday, generally as of the regularly scheduled close of business of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m., Eastern time) on each day that the NYSE is open for trading, based on prices at the time of closing provided that (a) any Fund assets or liabilities denominated in currencies other than

the U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers (as detailed below) and (b) U.S. fixed income assets may be valued as of the announced closing time for trading in fixed income instruments in a particular market or exchange. The NAV of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets held by the Fund, and its liabilities, are determined pursuant to valuation policies and procedures approved by the Board. The Fund’s assets and liabilities are valued primarily on the basis of market quotations.

Equity investments are valued at market value, which is generally determined using the last reported official closing price or last trading price on the exchange or market on which the security is primarily traded at the time of valuation.

Generally, trading in foreign securities, U.S. government securities, money market instruments and certain fixed-income securities is substantially completed each day at various times prior to the close of business on the NYSE. The values of such securities used in computing the NAV of the Fund are determined as of such times.

When market quotations are not readily available or are believed by BFA to be unreliable, the Fund’s investments are valued at fair value. Fair value determinations are made by BFA in accordance with policies and procedures approved by the Fund’s Board. BFA may conclude that a market quotation is not readily available or is unreliable if a security or other asset or liability does not have a price source due to its lack of liquidity, if a market quotation differs significantly from recent price quotations or otherwise no longer appears to reflect fair value, where the security or other asset or liability is thinly traded, or where there is a significant event subsequent to the most recent market quotation. A “significant event” is an event that, in the judgment of BFA, is likely to cause a material change to the closing market price of the asset or liability held by the Fund. Foreign securities whose values are affected by volatility that occurs in U.S. markets on a trading day after the close of foreign securities markets may be fair valued.

Fair value represents a good faith approximation of the value of an asset or liability. The fair value of an asset or liability held by the Fund is the amount the Fund might reasonably expect to receive from the current sale of that asset or the cost to extinguish that liability in an arm’s-length transaction. Valuing the Fund’s investments using fair value pricing will result in prices that may differ from current market valuations and that may not be the price at which those investments could have been sold during the period in which the particular fair values were used. Use of fair value prices and certain current market valuations could result in a difference between the prices used to calculate the Fund’s NAV and the prices used by the Underlying Index, which, in turn, could result in a difference between the Fund’s performance and the performance of the Underlying Index.

Dividends and Distributions

General Policies. Dividends from net investment income, if any, generally are declared and paid quarterly by the Fund. Distributions of net realized securities gains, if any, generally are declared and paid once a year, but the Trust may make distributions on a more frequent basis for the Fund. The Trust reserves the right to declare special distributions if, in its reasonable discretion, such action is necessary or advisable to preserve its status as a regulated investment company (“RIC”) or to avoid imposition of income or excise taxes on undistributed income or realized gains.

Dividends and other distributions on shares of the Fund are distributed on a pro rata basis to beneficial owners of such shares. Dividend payments are made through DTC participants and indirect participants to beneficial owners then of record with proceeds received from the Fund.

Dividend Reinvestment Service. No dividend reinvestment service is provided by the Trust. Broker-dealers may make available the DTC book-entry Dividend Reinvestment Service for use by beneficial owners of the Fund for reinvestment of their dividend distributions. Beneficial owners should contact their broker to determine the availability and costs of the service and the details of participation therein. Brokers may require beneficial owners to adhere to specific procedures and timetables. If this service is available and used, dividend distributions of both income and realized gains will be automatically reinvested in additional whole shares of the Fund purchased in the secondary market.

Taxes. As with any investment, you should consider how your investment in shares of the Fund will be taxed. The tax information in this Prospectus is provided as general information, based on current law. You should consult your own tax professional about the tax consequences of an investment in shares of the Fund.

Unless your investment in Fund shares is made through a tax-exempt entity or tax-deferred retirement account, such as an IRA, you need to be aware of the possible tax consequences when the Fund makes distributions or you sell Fund shares.

Taxes on Distributions. Distributions from the Fund’s net investment income (other than qualified dividend income), including distributions of income from securities lending and distributions out of the Fund’s net short-term capital gains, if any, are taxable to you as ordinary income. Distributions by the Fund of net long-term capital gains in excess of net short-term capital losses (capital gain dividends) are taxable to you as long-term capital gains, generally at a 15% tax rate (0% at certain income levels), regardless of how long you have held the Fund’s shares. Distributions by the Fund that qualify as qualified dividend income are taxable to you at long-term capital gain rates for taxable years beginning on or before December 31, 2012. The 15% and 0% tax rates expire for taxable years beginning after December 31, 2012. Maximum long-term capital gain income tax rates are scheduled to rise to 20% in 2013. Beginning in 2013, a 3.8% U.S. federal Medicare contribution tax will be imposed on “net investment income,” including interest, dividends, and capital gains, of U.S. individuals with income exceeding $200,000 (or $250,000 if married and filing jointly), and of estates and trusts.

Dividends will be qualified dividend income to you if they are attributable to qualified dividend income received by the Fund. Generally, qualified dividend income includes dividend income from taxable U.S. corporations and qualified non-U.S. corporations, provided that the Fund satisfies certain holding period requirements in respect of the stock of such corporations and has not hedged its position in the stock in certain ways. Substitute dividends received by the Fund with respect to dividends paid on securities lent out will not be qualified dividend income. For this purpose, a qualified non-U.S. corporation means any non-U.S. corporation that is eligible for benefits under a comprehensive income tax treaty with the United States, which includes an exchange of information program or if the stock with respect to which the dividend was paid is readily tradable on an established United States securities market. The term excludes a corporation that is a passive foreign investment company.

Dividends received by the Fund from a real estate investment trust (“REIT”) or another RIC generally are qualified dividend income only to the extent the dividend distributions are made out of qualified dividend income received by such REIT or RIC. It is expected that dividends received by the Fund from a REIT and distributed to a shareholder generally will be taxable to the shareholder as ordinary income.

For a dividend to be treated as qualified dividend income, the dividend must be received with respect to a share of stock held without being hedged by the Fund, and with respect to a share of the Fund held without being hedged by you, for 61 days during the 121-day period beginning at the date which is 60 days before the date on which such share becomes ex-dividend with respect to such dividend or, in the case of certain preferred stock, 91 days during the 181-day period beginning 90 days before such date.

If your Fund shares are loaned out pursuant to a securities lending arrangement, you may lose the ability to use foreign tax credits passed through by the Fund or to treat Fund dividends paid while the shares are held by the borrower as qualified dividend income.

In general, your distributions are subject to U.S. federal income tax for the year when they are paid. Certain distributions paid in January, however, may be treated as paid on December 31 of the prior year.

If the Fund’s distributions exceed current and accumulated earnings and profits, all or a portion of the distributions made in the taxable year may be recharacterized as a return of capital to shareholders. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and result in a higher capital gain or lower capital loss when those shares on which the distribution was received are sold. Once a shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain, if the shareholder holds shares of the Fund as capital assets.

If you are neither a resident nor a citizen of the United States or if you are a non-U.S. entity, the Fund’s ordinary income dividends (which include distributions of net short-term capital gains) will generally be subject to a 30% U.S. withholding tax, unless a lower treaty rate applies, provided that withholding tax will generally not apply to any gain or income realized by a non-U.S. shareholder in respect of any distributions of long-term capital gains or upon the sale or other disposition of shares of the Fund.

A 30% withholding tax will be imposed on dividends paid after December 31, 2013, and redemption proceeds paid after December 31, 2014, to (i) foreign financial institutions including non-U.S. investment funds unless they agree to collect and disclose to the Internal Revenue Service (“IRS”) information regarding their direct and indirect U.S. account holders and (ii) certain other foreign entities, unless they certify certain information regarding their direct and indirect U.S. owners. To avoid withholding, foreign financial institutions will need to enter into agreements with the IRS that state that they will provide the IRS information, including the name, address and taxpayer identification number of direct and indirect U.S. account holders, comply with due diligence procedures with respect to the identification of U.S. accounts, report to the IRS certain information with respect to U.S. accounts maintained, agree to withhold tax on certain payments made to non-compliant foreign financial institutions or to account holders who fail to provide the required information, and determine certain other information as to their account holders. Other foreign entities will need to provide the name, address, and taxpayer identification number of each substantial U.S. owner or certifications of no substantial U.S. ownership unless certain exceptions apply.

Dividends, interest and capital gains received by the Fund with respect to non-U.S. securities may give rise to withholding and other taxes imposed by non-U.S. countries. Tax conventions between certain countries and the United States may reduce or eliminate such taxes.

If you are a resident or a citizen of the United States, by law, back-up withholding will apply to your distributions and proceeds if you have not provided a taxpayer identification number or social security number and made other required certifications.

Taxes When Shares are Sold. Currently, any capital gain or loss realized upon a sale of Fund shares is generally treated as a long-term gain or loss if the shares have been held for more than one year. Any capital gain or loss realized upon a sale of Fund shares held for one year or less is generally treated as short-term gain or loss, except that any capital loss on the sale of shares held for six months or less is treated as long-term capital loss to the extent that capital gain dividends were paid with respect to such shares. Beginning in 2013, any such capital gains, including from sales of Fund shares or from capital gain dividends, will be included in “net investment income” for purposes of the 3.8% U.S. federal Medicare contribution tax mentioned above.

The foregoing discussion summarizes some of the consequences under current U.S. federal tax law of an investment in the Fund. It is not a substitute for personal tax advice. You may also be subject to state and local taxation on Fund distributions and sales of shares. Consult your personal tax adviser about the potential tax consequences of an investment in shares of the Fund under all applicable tax laws.

Creations and Redemptions. Prior to trading in the secondary market, shares of the Fund are “created” at NAV by market makers, large investors and institutions only in block-size Creation Units of 50,000 shares or multiples thereof. Each “creator” or “Authorized Participant” enters into an authorized participant agreement with the Fund’s distributor, SEI Investments Distribution Co. (the “Distributor”). Only an Authorized Participant may create or redeem Creation Units directly with the Fund. A creation transaction, which is subject to acceptance by the transfer agent, generally

takes place when an Authorized Participant deposits into the Fund a designated portfolio of securities and a specified amount of cash approximating the holdings of the Fund in exchange for a specified number of Creation Units. To the extent practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund.

Similarly, shares can be redeemed only in Creation Units, generally for a designated portfolio of securities and a specified amount of cash held by the Fund (“Fund Securities”). Except when aggregated in Creation Units, shares are not redeemable by the Fund. The prices at which creations and redemptions occur are based on the next calculation of NAV after an order is received in a form described in the authorized participant agreement.

The Fund intends to comply with the U.S. federal securities laws in accepting securities for deposit and satisfying redemptions with redemption securities by, among other means, assuring that any securities accepted for deposit and any securities used to satisfy redemption requests will be sold in transactions that would be exempt from registration under the Securities Act of 1933, as amended (the “1933 Act”). Further, an Authorized Participant that is not a “qualified institutional buyer,” as such term is defined under Rule 144A of the 1933 Act, will not be able to receive Fund Securities that are restricted securities eligible for resale under Rule 144A.

Creations and redemptions must be made through a firm that is either a member of the Continuous Net Settlement System of the National Securities Clearing Corporation or a DTC participant and has executed an agreement with the Distributor with respect to creations and redemptions of Creation Unit aggregations. Information about the procedures regarding creation and redemption of Creation Units (including the cut-off times for receipt of creation and redemption orders) is included in the Fund’s SAI.

Because new shares may be created and issued on an ongoing basis, at any point during the life of the Fund a “distribution,” as such term is used in the 1933 Act, may be occurring. Broker-dealers and other persons are cautioned that some activities on their part may, depending on the circumstances, result in their being deemed participants in a distribution in a manner that could render them statutory underwriters and subject to the prospectus delivery and liability provisions of the 1933 Act. Any determination of whether one is an underwriter must take into account all the relevant facts and circumstances of each particular case.

Broker-dealers should also note that dealers who are not “underwriters” but are participating in a distribution (as contrasted to ordinary secondary transactions), and thus dealing with shares that are part of an “unsold allotment” within the meaning of Section 4(3)(C) of the 1933 Act, would be unable to take advantage of the prospectus delivery exemption provided by Section 4(3) of the 1933 Act. For delivery of prospectuses to exchange members, the prospectus delivery mechanism of Rule 153 under the 1933 Act is available only with respect to transactions on a national securities exchange.

Costs Associated with Creations and Redemptions. Authorized Participants are charged standard creation and redemption transaction fees to offset transfer and other transaction costs associated with the issuance and redemption of Creation

Units. The standard creation and redemption transaction fees are set forth in the table below. The standard creation transaction fee is charged to the Authorized Participant on the day such Authorized Participant creates a Creation Unit, and is the same regardless of the number of Creation Units purchased by the Authorized Participant on the applicable business day. Similarly, the standard redemption transaction fee is charged to the Authorized Participant on the day such Authorized Participant redeems a Creation Unit, and is the same regardless of the number of Creation Units redeemed by the Authorized Participant on the applicable business day. Creations and redemptions for cash (when cash creations and redemptions (in whole or in part) are available or specified) are also subject to an additional charge (up to the maximum amounts shown in the table below). This charge is intended to compensate for brokerage, tax, foreign exchange, execution, market impact and other costs and expenses related to cash transactions. Investors who use the services of a broker or other financial intermediary may pay fees for such services.

The following table shows, as of September 30, 2011, the approximate value of one Creation Unit, standard fees and maximum additional charges for creations and redemptions (as described above):

Householding. Householding is an option available to certain Fund investors. Householding is a method of delivery, based on the preference of the individual investor, in which a single copy of certain shareholder documents can be delivered to investors who share the same address, even if their accounts are registered under different names. Please contact your broker-dealer if you are interested in enrolling in householding and receiving a single copy of prospectuses and other shareholder documents, or if you are currently enrolled in householding and wish to change your householding status.

Distribution

The Distributor distributes Creation Units for the Fund on an agency basis. The Distributor does not maintain a secondary market in shares of the Fund. The Distributor has no role in determining the policies of the Fund or the securities that are purchased or sold by the Fund. The Distributor’s principal address is One Freedom Valley Drive, Oaks, PA 19456.

In addition, BFA or its Affiliates make payments to broker-dealers, banks or other financial intermediaries (together, “intermediaries”) related to marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems, or their making shares of the Fund and

certain other iShares funds available to their customers. Such payments, which may be significant to the intermediary, are not made by the Fund. Rather, such payments are made by BFA or its Affiliates from their own resources, which come directly or indirectly in part from fees paid by the iShares funds complex. Payments of this type are sometimes referred to as revenue-sharing payments. A financial intermediary may make decisions about which investment options it recommends or makes available, or the level of services provided, to its customers based on the revenue-sharing payments it is eligible to receive. Therefore, such payments to an intermediary create conflicts of interest between the intermediary and its customers and may cause the intermediary to recommend the Fund or other iShares funds over another investment. More information regarding these payments is contained in the Fund’s SAI. Please contact your salesperson or other investment professional for more information regarding any such payments his or her firm may receive from BFA or its Affiliates.

Financial Highlights

The financial highlights table is intended to help investors understand the Fund’s financial performance for the past five years. Certain information reflects financial results for a single share of the Fund. The total returns in the table represent the rate that an investor would have earned (or lost) on an investment in the Fund, assuming reinvestment of all dividends and distributions. This information has been audited by PricewaterhouseCoopers LLP, whose report is included, along with the Fund’s financial statements, in the Fund’s Annual Report (available upon request).

Supplemental Information

I. Premium/Discount Information

The table that follows presents information about the differences between the daily market price on secondary markets for shares of the Fund and the Fund’s NAV. NAV is the price at which the Fund issues and redeems shares. It is calculated in accordance with the standard formula for valuing mutual fund shares. The price used to calculate market returns (“Market Price”) of the Fund generally is determined using the midpoint between the highest bid and the lowest offer on the primary securities exchange on which shares of the Fund are listed for trading, as of the time that the Fund’s NAV is calculated. The Fund’s Market Price may be at, above or below its NAV. The NAV of the Fund will fluctuate with changes in the value of its portfolio holdings. The Market Price of the Fund will fluctuate in accordance with changes in its NAV, as well as market supply and demand.

Premiums or discounts are the differences (expressed as a percentage) between the NAV and Market Price of the Fund on a given day, generally at the time the NAV is calculated. A premium is the amount that the Fund is trading above the reported NAV, expressed as a percentage of the NAV. A discount is the amount that the Fund is trading below the reported NAV, expressed as a percentage of the NAV.

The following information shows the frequency of distributions of premiums and discounts for the Fund for each full calendar quarter of 2010 through September 30, 2011.

Each line in the table shows the number of trading days in which the Fund traded within the premium/discount range indicated. The number of trading days in each premium/discount range is also shown as a percentage of the total number of trading days in the period covered by the table. All data presented here represents past performance, which cannot be used to predict future results.

Premium/Discount Range
Number of Days
Percentage of Total Days
Between 0.5% and -0.5% 440 99.77%
Less than -0.5% 1 0.23
   441 100.00%

II. Total Return Information

The tables that follow present information about the total returns of the Fund and the Underlying Index as of the fiscal year ended July 31, 2011.

“Average Annual Total Returns” represent the average annual change in value of an investment over the periods indicated. “Cumulative Total Returns” represent the total change in value of an investment over the periods indicated.

The Fund’s NAV is the value of one share of the Fund as calculated in accordance with the standard formula for valuing mutual fund shares. The NAV return is based on the NAV of the Fund and the market return is based on the Market Price of the Fund. Market Price is determined by using the midpoint between the highest bid and the lowest offer on the primary stock exchange on which shares of the Fund are listed for trading, as of the time that the Fund’s NAV is calculated. Since shares of the Fund did not trade in the secondary market until after the Fund’s inception, for the period from inception to the first day of secondary market trading in shares of the Fund, the NAV of the Fund is used as a proxy for the Market Price to calculate market returns. Market and NAV returns assume that dividends and capital gain distributions have been reinvested in the Fund at Market Price and NAV, respectively.

An index is a statistical composite that tracks a specified financial market or sector. Unlike the Fund, the Underlying Index does not actually hold a portfolio of securities and therefore does not incur the expenses incurred by the Fund. These expenses negatively impact the performance of the Fund. Also, market returns do not include brokerage commissions that may be payable on secondary market transactions. If brokerage commissions were included, market returns would be lower. The returns shown in the following tables do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption or sale of Fund shares. The investment return and principal value of shares of the Fund will vary with changes in market conditions. Shares of the Fund may be worth more or less than their original cost when they are redeemed or sold in the market. The Fund’s past performance is no guarantee of future results.

Fund Overview

iSHARES® S&P NORTH AMERICAN TECHNOLOGY SECTOR INDEX FUND

Ticker: IGM Stock Exchange: NYSE Arca

Investment Objective

The iShares S&P North American Technology Sector Index FundTM (the “Fund”) seeks investment results that correspond generally to the price and yield performance, before fees and expenses, of the S&P North American Technology Sector IndexTM (the “Underlying Index”).

Fees and Expenses

The following table describes the fees and expenses that you will incur if you own shares of the Fund. The investment advisory agreement between iShares Trust (the “Trust”) and BlackRock Fund Advisors (“BFA”) (the “Investment Advisory Agreement”) provides that BFA will pay all operating expenses of the Fund, except interest expenses, taxes, brokerage expenses, future distribution fees or expenses, and extraordinary expenses.

You may also incur usual and customary brokerage commissions when buying or selling shares of the Fund, which are not reflected in the example that follows:

Annual Fund Operating Expenses

Example. This Example is intended to help you compare the cost of owning shares of the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

Portfolio Turnover. The Fund may pay transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 12% of the average value of its portfolio.

Principal Investment Strategies

The Underlying Index measures the performance of U.S.-traded stocks of technology-related companies in the U.S. and Canada. The Underlying Index includes companies in the following categories: producers of sophisticated computer-related devices; communications equipment and internet services; producers of computer and internet software; consultants for information technology; providers of computer services; and semiconductors and semiconductor equipment manufacturers.

BFA uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to “beat” the index it tracks and does not seek temporary defensive positions when markets decline or appear overvalued.

Indexing may eliminate the chance that the Fund will substantially outperform the Underlying Index but also may reduce some of the risks of active management, such as poor security selection. Indexing seeks to achieve lower costs and better after-tax performance by keeping portfolio turnover low in comparison to actively managed investment companies.

BFA uses a representative sampling indexing strategy to manage the Fund. “Representative sampling” is an indexing strategy that involves investing in a representative sample of securities that collectively has an investment profile similar to the Underlying Index. The securities selected are expected to have, in the aggregate, investment characteristics (based on factors such as market capitalization and industry weightings), fundamental characteristics (such as return variability and yield) and liquidity measures similar to those of the Underlying Index. The Fund may or may not hold all of the securities in the Underlying Index.

The Fund generally invests at least 90% of its assets in securities of the Underlying Index and in depositary receipts representing securities of the Underlying Index. The Fund may invest the remainder of its assets in securities not included in the Underlying Index, but which BFA believes will help the Fund track the Underlying Index and in other investments including futures contracts, options on futures contracts, options and swaps as well as cash and cash equivalents, including shares of money market funds advised by BFA or its affiliates.

The Fund may lend securities representing up to one-third of the value of the Fund’s total assets (including the value of the collateral received).

The Underlying Index is sponsored by an organization (the “Index Provider”) that is independent of the Fund and BFA. The

S-2   


Table Of Contents



Index Provider determines the composition and relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index. The Fund’s Index Provider is Standard & Poor’s Financial Services LLC (a subsidiary of The McGraw-Hill Companies) (“S&P”).

Industry Concentration Policy. The Fund will concentrate its investments (i.e., hold 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. For purposes of this limitation, securities of the U.S. government (including its agencies and instrumentalities) and repurchase agreements collateralized by U.S. government securities are not considered to be issued by members of any industry.

Summary of Principal Risks

As with any investment, you could lose all or part of your investment in the Fund, and the Fund’s performance could trail that of other investments. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund’s net asset value per share (“NAV”), trading price, yield, total return and ability to meet its investment objective.

Asset Class Risk. Securities in the Underlying Index or in the Fund’s portfolio may underperform in comparison to the general securities markets or other asset classes.

Concentration Risk. To the extent that the Fund’s investments are concentrated in a particular issuer, region, country, market, industry or asset class, the Fund may be susceptible to loss due to adverse occurrences affecting that issuer, region, country, market, industry or asset class.

Equity Securities Risk. Equity securities are subject to changes in value and their values may be more volatile than other asset classes.

Information Technology Sector Risk. Information technology companies face intense competition and potentially rapid product obsolescence. They are also heavily dependent on intellectual property rights and may be adversely affected by loss or impairment of those rights.

Issuer Risk. Fund performance depends on the performance of individual securities to which the Fund has exposure. Changes to the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA’s investment management strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares, losses from trading in secondary markets, periods of high volatility and disruption in the creation/redemption process of the Fund. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV.



S-3   


Table Of Contents



Non-Diversification Risk. The Fund may invest a large percentage of its assets in securities issued by or representing a small number of issuers. As a result, the Fund’s performance may depend on the performance of a small number of issuers.

Passive Investment Risk. The Fund is not actively managed and BFA does not attempt to take defensive positions under any market conditions, including declining markets.

Securities Lending Risk. The Fund may engage in securities lending. Securities lending involves the risk that the Fund may lose money because the borrower of the Fund’s loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Technology Sector Risk. Technology companies may have limited product lines, markets, financial resources or personnel. Technology companies typically face intense competition and potentially rapid product obsolescence. They are also heavily dependent on intellectual property rights and may be adversely affected by loss or impairment of those rights.

Tracking Error Risk. The performance of the Fund may diverge from that of the Underlying Index. Because the Fund employs a representative sampling strategy, the Fund may experience tracking error to a greater extent than a fund that seeks to replicate an index.

1 After-tax returns in the table above are calculated using the historical highest individual U.S. federal marginal income tax rates and do not reflect the impact of state or local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown, and after-tax returns shown are not relevant to tax-exempt investors or investors who hold shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts (“IRAs”). Fund returns after taxes on distributions and sale of Fund shares are calculated assuming that an investor has sufficient capital gains of the same character from other investments to offset any capital losses from the sale of Fund shares. As a result, Fund returns after taxes on distributions and sale of Fund shares may exceed Fund returns before taxes and/or returns after taxes on distributions.

Management

Investment Adviser. BlackRock Fund Advisors.

Portfolio Managers. Rene Casis, Diane Hsiung and Greg Savage (the “Portfolio Managers”) are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager supervises a portfolio management team. Mr. Casis, Ms. Hsiung and Mr. Savage have been Portfolio Managers of the Fund since 2010, 2008 and 2008, respectively.

Purchase and Sale of Fund Shares

The Fund is an exchange-traded fund (commonly referred to as an “ETF”). Individual Fund shares may only be purchased and sold on a national securities exchange through a broker-dealer. The price of Fund shares is based on market price, and because ETF shares trade at market prices rather than NAV, shares may trade at a price greater than NAV (a premium) or less than NAV (a discount). The Fund will only issue or redeem shares that have been aggregated into blocks of 50,000 shares or multiples thereof (“Creation Units”) to authorized participants who have entered into agreements with the Fund’s distributor. The Fund generally will issue or redeem Creation Units in return for a designated portfolio of securities (and an amount of cash) that the Fund specifies each day.

Tax Information

The Fund intends to make distributions that may be taxable to you as ordinary income or capital gains, unless you are investing through a tax-deferred arrangement such as a 401(k) plan or an IRA.

Payments to Broker-Dealers and other Financial Intermediaries

If you purchase shares of the Fund through a broker-dealer or other financial intermediary (such as a bank), BFA or other related companies may pay the intermediary for marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems or other services related to the sale or promotion of the Fund. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.

More Information About the Fund

This Prospectus contains important information about investing in the Fund. Please read this Prospectus carefully before you make any investment decisions. Additional information regarding the Fund is available at www.iShares.com.

BFA is the investment adviser to the Fund. Shares of the Fund are listed for trading on NYSE Arca, Inc. (“NYSE Arca”). The market price for a share of the Fund may be different from the Fund’s most recent NAV.

ETFs are funds that trade like other publicly-traded securities. The Fund is designed to track an index. Similar to shares of an index mutual fund, each share of the Fund represents a partial ownership in an underlying portfolio of securities intended to track a market index. Unlike shares of a mutual fund, which can be bought and redeemed from the issuing fund by all shareholders at a price based on NAV, shares of the Fund may be purchased or redeemed directly from the Fund at NAV solely by authorized participants. Also unlike shares of a mutual fund, shares of the Fund are listed on a national securities exchange and trade in the secondary market at market prices that change throughout the day.

The Fund invests in a particular segment of the securities markets and seeks to track the performance of a securities index that generally is not representative of the market as a whole. The Fund is designed to be used as part of broader asset allocation strategies. Accordingly, an investment in the Fund should not constitute a complete investment program.

An index is a theoretical financial calculation while the Fund is an actual investment portfolio. The performance of the Fund and the Underlying Index may vary due to transaction costs, non-U.S. currency valuations, asset valuations, corporate actions (such as mergers and spin-offs), timing variances and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions (such as diversification requirements) that apply to the Fund but not to the Underlying Index or to the use of representative sampling. “Tracking error” is the difference between the performance (return) of the Fund’s portfolio and that of the Underlying Index. BFA expects that, over time, the Fund’s tracking error will not exceed 5%. Because the Fund uses a representative sampling indexing strategy, it can be expected to have a larger tracking error than if it used a replication indexing strategy. “Replication” is an indexing strategy in which a fund invests in substantially all of the securities in its underlying index in approximately the same proportions as in the underlying index.

An investment in the Fund is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, BFA or any of its affiliates.

The Fund’s investment objective and the Underlying Index may be changed without shareholder approval.

A Further Discussion of Principal Risks

The Fund is subject to various risks, including the principal risks noted below, any of which may adversely affect the Fund’s NAV, trading price, yield, total return and ability to meet its investment objective. You could lose all or part of your investment in the Fund, and the Fund could underperform other investments.

Asset Class Risk. The securities in the Underlying Index or in the Fund’s portfolio may underperform the returns of other securities or indexes that track other industries, groups of industries, markets, asset classes or sectors. Various types of securities or indexes tend to experience cycles of outperformance and underperformance in comparison to the general securities markets.

Concentration Risk. To the extent that the Fund’s portfolio reflects the Underlying Index’s concentration in the securities of a particular issuer or issuers in a particular country, group of countries, region, market, industry, group of industries, sector or asset class, the Fund may be adversely affected by the performance of those securities, may be subject to increased price volatility and may be more susceptible to adverse economic, market, political or regulatory occurrences affecting that issuer, country, group of countries, region, market, industry, group of industries, sector or asset class.

Equity Securities Risk. The Fund invests in equity securities, which are subject to changes in value that may be attributable to market perception of a particular issuer or to general stock market fluctuations that affect all issuers. Investments in equity securities may be more volatile than investments in other asset classes.

Information Technology Sector Risk. Information technology companies face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Like other technology companies, information technology companies may have limited product lines, markets, financial resources or personnel. The products of information technology companies may face obsolescence due to rapid technological developments and frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Companies in the information technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies.

Issuer Risk. The performance of the Fund depends on the performance of individual securities to which the Fund has exposure. Any issuer of these securities may perform poorly, causing the value of its securities to decline. Poor performance may be caused by poor management decisions, competitive pressures, changes in technology, expiration of patent protection, disruptions in supply, labor problems or shortages, corporate restructurings, fraudulent disclosures or other factors. Issuers may, in times of distress or at their own discretion, decide to reduce or eliminate dividends, which may also cause their stock prices to decline.

Management Risk. The Fund may not fully replicate the Underlying Index and may hold securities not included in the Underlying Index. As a result, the Fund is subject to the risk that BFA’s investment management strategy, the implementation of which is subject to a number of constraints, may not produce the intended results.

Market Risk. The Fund could lose money due to short-term market movements and over longer periods during market downturns. Securities may decline in value due to factors affecting securities markets generally or particular industries represented in the markets. The value of a security may decline due to general market conditions, economic trends or events that are not specifically related to the issuer of the security or to factors that affect a particular industry or industries. During a general downturn in the securities markets, multiple asset classes may be negatively affected.

Market Trading Risk

Absence of Active Market. Although shares of the Fund are listed for trading on one or more stock exchanges, there can be no assurance that an active trading market for such shares will develop or be maintained.

Risk of Secondary Listings. The Fund’s shares may be listed or traded on U.S. and non-U.S. stock exchanges other than the U.S. stock exchange where the Fund’s primary listing is maintained. There can be no assurance that the Fund’s shares will continue to trade on any such stock exchange or in any market or that the Fund’s shares will continue to meet the requirements for listing or trading on any exchange or in any market. The Fund’s shares may be less actively traded in certain markets than others, and investors are subject to the execution and settlement risks and market standards of the market where they or their broker direct their trades for execution. Certain information available to investors who trade Fund shares on a U.S. stock exchange during regular U.S. market hours may not be available to investors who trade in other markets, which may result in secondary market prices in such markets being less efficient.

Secondary Market Trading Risk. Shares of the Fund may trade in the secondary market at times when the Fund does not accept orders to purchase or redeem shares. At such times, shares may trade in the secondary market with more significant premiums or discounts than might be experienced at times when the Fund accepts purchase and redemption orders.

Secondary market trading in Fund shares may be halted by a stock exchange because of market conditions or other reasons. In addition, trading in Fund shares on a stock exchange or in any market may be subject to trading halts caused by extraordinary market volatility pursuant to “circuit breaker” rules on the stock exchange or market. There can be no assurance that the requirements necessary to maintain the listing or trading of Fund shares will continue to be met or will remain unchanged.

Shares of the Fund May Trade at Prices Other Than NAV. Shares of the Fund trade on stock exchanges at prices at, above or below their most recent NAV. The NAV of the Fund is calculated at the end of each business day and fluctuates with changes in the market value of the Fund’s holdings since the most recent calculation. The trading prices of the Fund’s shares fluctuate continuously throughout trading hours based on market supply and demand rather than NAV. The trading prices of the Fund’s shares may deviate significantly from NAV during periods of market volatility. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV. However, because shares can be created and redeemed in Creation Units at NAV (unlike shares of many closed-end funds, which

frequently trade at appreciable discounts from, and sometimes at premiums to, their NAVs), BFA believes that large discounts or premiums to the NAV of the Fund are not likely to be sustained over the long-term. While the creation/redemption feature is designed to make it likely that the Fund’s shares normally will trade on stock exchanges at prices close to the Fund’s next calculated NAV, exchange prices are not expected to correlate exactly with the Fund’s NAV due to timing reasons as well as market supply and demand factors. In addition, disruptions to creations and redemptions or extreme market volatility may result in trading prices for shares of the Fund that differ significantly from its NAV.

Costs of Buying or Selling Fund Shares. Buying or selling Fund shares on an exchange involves two types of costs that apply to all securities transactions. When buying or selling shares of the Fund through a broker, you will likely incur a brokerage commission or other charges imposed by brokers as determined by that broker. In addition, you may incur the cost of the “spread” – that is, the difference between what investors are willing to pay for Fund shares (the “bid” price) and the price at which they are willing to sell Fund shares (the “ask” price). Because of the costs inherent in buying or selling Fund shares, frequent trading may detract significantly from investment results and an investment in Fund shares may not be advisable for investors who anticipate regularly making small investments.

Non-Diversification Risk. The Fund is classified as “non-diversified.” This means that the Fund may invest a large percentage of its assets in securities issued by or representing a small number of issuers. As a result, the Fund may be more susceptible to the risks associated with these particular issuers, or to a single economic, political or regulatory occurrence affecting these issuers.

Passive Investment Risk. The Fund is not actively managed and may be affected by a general decline in market segments related to the Underlying Index. The Fund invests in securities included in, or representative of, the Underlying Index regardless of their investment merits. BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

Securities Lending Risk. The Fund may engage in securities lending. Securities lending involves the risk that the Fund may lose money because the borrower of the Fund’s loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for the loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Technology Sector Risk. The Fund invests in technology companies, which face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Technology companies may have limited product lines, markets, financial resources or personnel. The products of technology companies may face obsolescence due to rapid technological developments and frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Companies in the technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies.

Tracking Error Risk. Imperfect correlation between the Fund’s portfolio securities and those in the Underlying Index, rounding of prices, changes to the Underlying Index and regulatory requirements may cause tracking error, which is the divergence of the Fund’s performance from that of the Underlying Index. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Underlying Index does not. Because the Fund employs a representative sampling strategy, the Fund may experience tracking error to a greater extent than a fund that seeks to replicate an index.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

Telecommunications Sector Risk. The telecommunications sector is subject to extensive government regulation. The costs of complying with governmental regulations, delays or failure to receive required regulatory approvals, or the enactment of new adverse regulatory requirements may negatively affect the business of the telecommunications companies. Government actions around the world, specifically in the area of pre-marketing clearance of products and prices, can be arbitrary and unpredictable. Companies in the telecommunications sector may encounter distressed cash flows due to the need to commit substantial capital to meet increasing competition, particularly in formulating new products and services using new technology. Technological innovations may make the products and services of telecommunications companies obsolete.

A description of the Trust’s policies and procedures with respect to the disclosure of the Fund’s portfolio securities is available in the Fund’s Statement of Additional Information (“SAI”). The top holdings of the Fund can be found at www.iShares.com. Fund fact sheets provide information regarding the Fund’s top holdings and may be requested by calling 1-800-iShares (1-800-474-2737).

Management

Investment Adviser. As investment adviser, BFA has overall responsibility for the general management and administration of the Trust. BFA provides an investment program for the Fund and manages the investment of the Fund’s assets. In managing the Fund, BFA may draw upon the research and expertise of its asset management affiliates with respect to certain portfolio securities. In seeking to achieve the Fund’s investment objective, BFA uses teams of portfolio managers, investment strategists and other investment specialists. This team approach brings together many disciplines and leverages BFA’s extensive resources.

Pursuant to the Investment Advisory Agreement between BFA and the Trust (entered into on behalf of the Fund), BFA is responsible for substantially all expenses of the Fund, except interest expenses, taxes, brokerage expenses, future distribution fees or expenses and extraordinary expenses.

For its investment advisory services to the Fund, BFA is entitled to receive a management fee from the Fund corresponding to the Fund’s allocable portion of an aggregate management fee based on the aggregate average daily net assets of the following iShares funds: iShares PHLX SOX Semiconductor Sector Index Fund, iShares S&P Global Clean Energy Index Fund, iShares S&P Global Consumer Discretionary Sector Index Fund, iShares S&P Global Consumer Staples Sector Index Fund, iShares S&P Global Energy Sector Index Fund, iShares S&P Global Financials Sector Index Fund, iShares S&P Global Healthcare Sector Index Fund, iShares S&P Global Industrials Sector Index Fund, iShares S&P Global Infrastructure Index Fund, iShares S&P Global Materials Sector Index Fund, iShares S&P Global Nuclear Energy Index Fund, iShares S&P Global Technology Sector Index Fund, iShares S&P Global Telecommunications Sector Index Fund, iShares S&P Global Timber & Forestry Index Fund, iShares S&P Global Utilities Sector Index Fund, iShares S&P North American Natural Resources Sector Index Fund, iShares S&P North American Technology Sector Index Fund, iShares S&P North American Technology-Multimedia Networking Index Fund and iShares S&P North American Technology-Software Index Fund. The aggregate management fee is calculated as follows: 0.48% per annum of the aggregate net assets less than or equal to $10.0 billion, plus 0.43% per annum of the aggregate net assets over $10.0 billion, up to and including $20.0 billion, plus 0.38% per annum of the aggregate net assets in excess of $20.0 billion. As calculated on July 31, 2011, for its investment advisory services to the Fund, BFA is entitled to receive a management fee from the Fund, based on a percentage of the Fund’s average daily net assets, at an annual rate of 0.48%.

BFA is located at 400 Howard Street, San Francisco, CA 94105. It is a wholly owned subsidiary of BTC, which in turn is indirectly wholly-owned by BlackRock, Inc. (“BlackRock”). As of September 30, 2011, BTC and its affiliates, including BFA and BlackRock, provided investment advisory services for assets in excess of $3.35 trillion. BFA, BTC, BlackRock Execution Services, BlackRock and their affiliates deal, trade and invest for their own accounts in the types of securities in which the Fund may also invest.

A discussion regarding the basis for the Trust’s Board of Trustees’ (the “Board”) approval of the Investment Advisory Agreement with BFA is available in the Fund’s annual report for the period ended July 31.

Portfolio Managers. Rene Casis, Diane Hsiung and Greg Savage are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager is responsible for various functions related to portfolio management, including, but not limited to, investing cash inflows, coordinating with members of his or her portfolio management team to focus on certain asset classes, implementing investment strategy, researching and reviewing investment strategy and overseeing members of his or her portfolio management team that have more limited responsibilities.

Rene Casis has been employed by BFA (formerly, Barclays Global Fund Advisors (“BGFA”)) and BTC (formerly, Barclays Global Investors, N.A. (“BGI”)) as a senior portfolio manager since 2009. From 2005 to 2009, Mr. Casis was a trader at Barclays Capital. Prior to that, Mr. Casis was a portfolio manager from 2000 to 2005 for BGFA and BGI. Mr. Casis has been a Portfolio Manager of the Fund since 2010.

Diane Hsiung has been employed by BFA and BTC as a senior portfolio manager since 2007. Prior to that, Ms. Hsiung was a portfolio manager from 2002 to 2006 for BGFA and BGI. Ms. Hsiung has been a Portfolio Manager of the Fund since 2008.

Greg Savage has been employed by BFA and BTC as a senior portfolio manager since 2006. Prior to that, Mr. Savage was a portfolio manager from 2001 to 2006 for BGFA and BGI. Mr. Savage has been a Portfolio Manager of the Fund since 2008.

The Fund’s SAI provides additional information about the Portfolio Managers’ compensation, other accounts managed by the Portfolio Managers and the Portfolio Managers’ ownership (if any) of shares in the Fund.

Administrator, Custodian and Transfer Agent. State Street Bank and Trust Company (“State Street”) is the administrator, custodian and transfer agent for the Fund.

Conflicts of Interest. BFA wants you to know that there are certain entities with which BFA has relationships that may give rise to conflicts of interest, or the appearance of conflicts of interest. These entities include the following: BFA’s affiliates (including BlackRock and The PNC Financial Services Group, Inc., and each of their affiliates, directors, partners, trustees, managing members, officers and employees (collectively, the “Affiliates”)) and BlackRock’s significant shareholder, Barclays Bank PLC and its affiliates, including Barclays PLC (each, an “Entity” and together, the “Entities”).

The activities of BFA, the Affiliates and the Entities in the management of, or their interest in, their own accounts and other accounts they manage, may present conflicts of interest that could disadvantage the Fund and its shareholders. BFA and its Affiliates or the Entities provide investment management services to other funds and discretionary managed accounts that may follow an investment program similar to that of the Fund. BFA, its Affiliates and the Entities are involved worldwide with a broad spectrum of financial services and asset management activities and may engage in the ordinary course of business in activities in which their interests or the interests of their clients may conflict with those of the Fund. BFA, one or more of the Affiliates or the Entities acts, or may act, as an investor, investment banker, research provider, investment manager, financier, underwriter, advisor, market maker, trader, prime broker, lender, agent or principal, and have other direct and indirect interests, in securities, currencies and other instruments in which the Fund may directly or indirectly invest. Thus, it is likely that the Fund will have multiple business relationships with and will invest in, engage in transactions with, make voting decisions with respect to, or obtain services from, entities for which BFA, an Affiliate or an Entity performs or seeks to perform investment banking or other services.

BFA or one or more Affiliates or Entities may engage in proprietary trading and advise accounts and funds that have investment objectives similar to those of the Fund and/or that engage in and compete for transactions in the same types of securities, currencies and other instruments as the Fund, including in securities issued by other open-end and closed-end investment management companies, including investment companies that are affiliated with the Fund and BFA, to the extent permitted under the Investment Company Act of 1940, as amended (the “1940 Act”). The trading activities

of BFA, these Affiliates and Entities are carried out without reference to positions held directly or indirectly by the Fund and may result in BFA, an Affiliate or an Entity having positions that are adverse to those of the Fund.

No Affiliate or Entity is under any obligation to share any investment opportunity, idea or strategy with the Fund. As a result, an Affiliate or an Entity may compete with the Fund for appropriate investment opportunities. As a result of this and several other factors, the results of the Fund’s investment activities may differ from those of an Affiliate or an Entity and of other accounts managed by an Affiliate or an Entity, and it is possible that the Fund could sustain losses during periods in which one or more Affiliates or Entities and other accounts achieve profits on their trading for proprietary or other accounts. The opposite result is also possible.

The Fund may, from time to time, enter into transactions in which BFA or an Affiliate’s or an Entity’s clients have an interest adverse to the Fund. Furthermore, transactions undertaken by Affiliate-advised clients may adversely impact the Fund. Transactions by one or more Affiliate- or Entity-advised clients or BFA may have the effect of diluting or otherwise disadvantaging the values, prices or investment strategies of the Fund.

An Entity may maintain securities indices as part of its product offerings. Index-based funds seek to track the performance of securities indices and may use the name of the index in the fund name. Index providers, including the Entities, may be paid licensing fees for use of their indices or index names. Entities will not be obligated to license their indices to BFA and its Affiliates, and BFA and its Affiliates will not be assured that the terms of any index licensing agreement with the Entities will be as favorable as those terms offered to other index licensees.

The Fund’s activities may be limited because of regulatory restrictions applicable to one or more Affiliates or Entities, and/or their internal policies designed to comply with such restrictions. In addition, the Fund may invest in securities of companies with which an Affiliate or an Entity has or is trying to develop investment banking relationships or in which an Affiliate or an Entity has significant debt or equity investments. The Fund also may invest in securities of companies for which an Affiliate or an Entity provides or may some day provide research coverage. An Affiliate or an Entity may have business relationships with and purchase or distribute or sell services or products from or to distributors, consultants or others who recommend the Fund or who engage in transactions with or for the Fund, and may receive compensation for such services. The Fund may also make brokerage and other payments to Affiliates or Entities in connection with the Fund’s portfolio investment transactions.

Pursuant to a securities lending program approved by the Board, the Fund has retained an Affiliate of BFA to serve as the securities lending agent for the Fund to the extent that the Fund participates in the securities lending program. For these services, the lending agent may receive a fee from the Fund, including a fee based on the returns earned on the Fund’s investment of the cash received as collateral for any loaned securities. In addition, one or more Affiliates may be among the entities to which the Fund may lend its portfolio securities under the securities lending program.

The activities of BFA, the Affiliates or Entities may give rise to other conflicts of interest that could disadvantage the Fund and its shareholders. BFA has adopted policies and

procedures designed to address these potential conflicts of interest. See the Fund’s SAI for further information.

Shareholder Information

Additional shareholder information, including how to buy and sell shares of the Fund, is available free of charge by calling toll-free: 1-800-iShares (1-800-474-2737) or visiting our website at www.iShares.com.

Buying and Selling Shares. Shares of the Fund may be acquired or redeemed directly from the Fund only in Creation Units or multiples thereof, as discussed in the Creations and Redemptions section of this Prospectus. Only an Authorized Participant (as defined in the Creations and Redemptions section) may engage in creation or redemption transactions directly with the Fund. Once created, shares of the Fund generally trade in the secondary market in amounts less than a Creation Unit.

Shares of the Fund are listed on a national securities exchange for trading during the trading day. Shares can be bought and sold throughout the trading day like shares of other publicly-traded companies. The Trust does not impose any minimum investment for shares of the Fund purchased on an exchange. The Fund’s shares trade under the trading symbol “IGM.”

Buying or selling Fund shares on an exchange involves two types of costs that may apply to all securities transactions. When buying or selling shares of the Fund through a broker, you will likely incur a brokerage commission or other charges determined by your broker. The commission is frequently a fixed amount and may be a significant proportional cost for investors seeking to buy or sell small amounts of shares. In addition, you may incur the cost of the “spread” – that is, any difference between the bid price and the ask price. The spread varies over time for shares of the Fund based on its trading volume and market liquidity, and is generally lower if the Fund has a lot of trading volume and market liquidity, and higher if the Fund has little trading volume and market liquidity.

The Board has adopted a policy of not monitoring for frequent purchases and redemptions of Fund shares (“frequent trading”) that appear to attempt to take advantage of a potential arbitrage opportunity presented by a lag between a change in the value of the Fund’s portfolio securities after the close of the primary markets for the Fund’s portfolio securities and the reflection of that change in the Fund’s NAV (“market timing”), because the Fund generally sells and redeems its shares directly through transactions that are in-kind and/or for cash, subject to the conditions described below under Creations and Redemptions. The Board has not adopted a policy of monitoring for other frequent trading activity because shares of the Fund are listed for trading on a national securities exchange.

The national securities exchange on which the Fund’s shares are listed is open for trading Monday through Friday and is closed on weekends and the following holidays: New Year’s Day, Martin Luther King, Jr. Day, Presidents’ Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day. The Fund’s primary listing exchange is NYSE Arca.

Section 12(d)(1) of the 1940 Act restricts investments by investment companies in the securities of other investment companies. Registered investment companies are permitted to invest in the Fund beyond the limits set forth in Section 12(d)(1), subject to certain terms and conditions set forth in SEC rules or in an SEC exemptive order issued to the Trust. In order for a registered investment company to invest in shares of the Fund beyond the limitations of Section 12(d)(1) pursuant to the exemptive relief obtained by the Trust, the registered investment company must enter into an agreement with the Trust.

Book Entry. Shares of the Fund are held in book-entry form, which means that no stock certificates are issued. The Depository Trust Company (“DTC”) or its nominee is the record owner of all outstanding shares of the Fund and is recognized as the owner of all shares for all purposes.

Investors owning shares of the Fund are beneficial owners as shown on the records of DTC or its participants. DTC serves as the securities depository for shares of the Fund. DTC participants include securities brokers and dealers, banks, trust companies, clearing corporations and other institutions that directly or indirectly maintain a custodial relationship with DTC. As a beneficial owner of shares, you are not entitled to receive physical delivery of stock certificates or to have shares registered in your name, and you are not considered a registered owner of shares. Therefore, to exercise any right as an owner of shares, you must rely upon the procedures of DTC and its participants. These procedures are the same as those that apply to any other securities that you hold in book-entry or “street name” form.

Share Prices. The trading prices of the Fund’s shares in the secondary market generally differ from the Fund’s daily NAV and are affected by market forces such as supply and demand, economic conditions and other factors. Information regarding the intraday value of shares of the Fund, also known as the “indicative optimized portfolio value” (“IOPV”), is disseminated every 15 seconds throughout the trading day by the national securities exchange on which the Fund’s shares are listed or by market data vendors or other information providers. The IOPV is based on the current market value of the securities and/or cash required to be deposited in exchange for a Creation Unit. The IOPV does not necessarily reflect the precise composition of the current portfolio of securities held by the Fund at a particular point in time or the best possible valuation of the current portfolio. Therefore, the IOPV should not be viewed as a “real-time” update of the Fund’s NAV, which is computed only once a day. The IOPV is generally determined by using both current market quotations and/or price quotations obtained from broker-dealers that may trade in the portfolio securities held by the Fund. The quotations of certain Fund holdings may not be updated during U.S. trading hours if such holdings do not trade in the United States. The Fund is not involved in, or responsible for, the calculation or dissemination of the IOPV and makes no representation or warranty as to its accuracy.

Determination of Net Asset Value. The NAV of the Fund normally is determined once daily Monday through Friday, generally as of the regularly scheduled close of business of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m., Eastern time) on each day that the NYSE is open for trading, based on prices at the time of closing provided that (a) any Fund assets or liabilities denominated in currencies other than

the U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers (as detailed below) and (b) U.S. fixed income assets may be valued as of the announced closing time for trading in fixed income instruments in a particular market or exchange. The NAV of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets held by the Fund, and its liabilities, are determined pursuant to valuation policies and procedures approved by the Board. The Fund’s assets and liabilities are valued primarily on the basis of market quotations.

Equity investments are valued at market value, which is generally determined using the last reported official closing price or last trading price on the exchange or market on which the security is primarily traded at the time of valuation.

Generally, trading in foreign securities, U.S. government securities, money market instruments and certain fixed-income securities is substantially completed each day at various times prior to the close of business on the NYSE. The values of such securities used in computing the NAV of the Fund are determined as of such times.

When market quotations are not readily available or are believed by BFA to be unreliable, the Fund’s investments are valued at fair value. Fair value determinations are made by BFA in accordance with policies and procedures approved by the Fund’s Board. BFA may conclude that a market quotation is not readily available or is unreliable if a security or other asset or liability does not have a price source due to its lack of liquidity, if a market quotation differs significantly from recent price quotations or otherwise no longer appears to reflect fair value, where the security or other asset or liability is thinly traded, or where there is a significant event subsequent to the most recent market quotation. A “significant event” is an event that, in the judgment of BFA, is likely to cause a material change to the closing market price of the asset or liability held by the Fund. Foreign securities whose values are affected by volatility that occurs in U.S. markets on a trading day after the close of foreign securities markets may be fair valued.

Fair value represents a good faith approximation of the value of an asset or liability. The fair value of an asset or liability held by the Fund is the amount the Fund might reasonably expect to receive from the current sale of that asset or the cost to extinguish that liability in an arm’s-length transaction. Valuing the Fund’s investments using fair value pricing will result in prices that may differ from current market valuations and that may not be the price at which those investments could have been sold during the period in which the particular fair values were used. Use of fair value prices and certain current market valuations could result in a difference between the prices used to calculate the Fund’s NAV and the prices used by the Underlying Index, which, in turn, could result in a difference between the Fund’s performance and the performance of the Underlying Index.

Dividends and Distributions

General Policies. Dividends from net investment income, if any, generally are declared and paid quarterly by the Fund. Distributions of net realized securities gains, if any, generally are declared and paid once a year, but the Trust may make distributions on a more frequent basis for the Fund. The Trust reserves the right to declare special distributions if, in its reasonable discretion, such action is necessary or advisable to preserve its status as a regulated investment company (“RIC”) or to avoid imposition of income or excise taxes on undistributed income or realized gains.

Dividends and other distributions on shares of the Fund are distributed on a pro rata basis to beneficial owners of such shares. Dividend payments are made through DTC participants and indirect participants to beneficial owners then of record with proceeds received from the Fund.

Dividend Reinvestment Service. No dividend reinvestment service is provided by the Trust. Broker-dealers may make available the DTC book-entry Dividend Reinvestment Service for use by beneficial owners of the Fund for reinvestment of their dividend distributions. Beneficial owners should contact their broker to determine the availability and costs of the service and the details of participation therein. Brokers may require beneficial owners to adhere to specific procedures and timetables. If this service is available and used, dividend distributions of both income and realized gains will be automatically reinvested in additional whole shares of the Fund purchased in the secondary market.

Taxes. As with any investment, you should consider how your investment in shares of the Fund will be taxed. The tax information in this Prospectus is provided as general information, based on current law. You should consult your own tax professional about the tax consequences of an investment in shares of the Fund.

Unless your investment in Fund shares is made through a tax-exempt entity or tax-deferred retirement account, such as an IRA, you need to be aware of the possible tax consequences when the Fund makes distributions or you sell Fund shares.

Taxes on Distributions. Distributions from the Fund’s net investment income (other than qualified dividend income), including distributions of income from securities lending and distributions out of the Fund’s net short-term capital gains, if any, are taxable to you as ordinary income. Distributions by the Fund of net long-term capital gains in excess of net short-term capital losses (capital gain dividends) are taxable to you as long-term capital gains, generally at a 15% tax rate (0% at certain income levels), regardless of how long you have held the Fund’s shares. Distributions by the Fund that qualify as qualified dividend income are taxable to you at long-term capital gain rates for taxable years beginning on or before December 31, 2012. The 15% and 0% tax rates expire for taxable years beginning after December 31, 2012. Maximum long-term capital gain income tax rates are scheduled to rise to 20% in 2013. Beginning in 2013, a 3.8% U.S. federal Medicare contribution tax will be imposed on “net investment income,” including interest, dividends, and capital gains, of U.S. individuals with income exceeding $200,000 (or $250,000 if married and filing jointly), and of estates and trusts.

Dividends will be qualified dividend income to you if they are attributable to qualified dividend income received by the Fund. Generally, qualified dividend income includes dividend income from taxable U.S. corporations and qualified non-U.S. corporations, provided that the Fund satisfies certain holding period requirements in respect of the stock of such corporations and has not hedged its position in the stock in certain ways. Substitute dividends received by the Fund with respect to dividends paid on securities lent out will not be qualified dividend income. For this purpose, a qualified non-U.S. corporation means any non-U.S. corporation that is eligible for benefits under a comprehensive income tax treaty with the United States, which includes an exchange of information program or if the stock with respect to which the dividend was paid is readily tradable on an established United States securities market. The term excludes a corporation that is a passive foreign investment company.

Dividends received by the Fund from a real estate investment trust (“REIT”) or another RIC generally are qualified dividend income only to the extent the dividend distributions are made out of qualified dividend income received by such REIT or RIC. It is expected that dividends received by the Fund from a REIT and distributed to a shareholder generally will be taxable to the shareholder as ordinary income.

For a dividend to be treated as qualified dividend income, the dividend must be received with respect to a share of stock held without being hedged by the Fund, and with respect to a share of the Fund held without being hedged by you, for 61 days during the 121-day period beginning at the date which is 60 days before the date on which such share becomes ex-dividend with respect to such dividend or, in the case of certain preferred stock, 91 days during the 181-day period beginning 90 days before such date.

If your Fund shares are loaned out pursuant to a securities lending arrangement, you may lose the ability to use foreign tax credits passed through by the Fund or to treat Fund dividends paid while the shares are held by the borrower as qualified dividend income.

In general, your distributions are subject to U.S. federal income tax for the year when they are paid. Certain distributions paid in January, however, may be treated as paid on December 31 of the prior year.

If the Fund’s distributions exceed current and accumulated earnings and profits, all or a portion of the distributions made in the taxable year may be recharacterized as a return of capital to shareholders. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and result in a higher capital gain or lower capital loss when those shares on which the distribution was received are sold. Once a shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain, if the shareholder holds shares of the Fund as capital assets.

If you are neither a resident nor a citizen of the United States or if you are a non-U.S. entity, the Fund’s ordinary income dividends (which include distributions of net short-term capital gains) will generally be subject to a 30% U.S. withholding tax, unless a lower treaty rate applies, provided that withholding tax will generally not apply to any gain or income realized by a non-U.S. shareholder in respect of any distributions of long-term capital gains or upon the sale or other disposition of shares of the Fund.

A 30% withholding tax will be imposed on dividends paid after December 31, 2013, and redemption proceeds paid after December 31, 2014, to (i) foreign financial institutions including non-U.S. investment funds unless they agree to collect and disclose to the Internal Revenue Service (“IRS”) information regarding their direct and indirect U.S. account holders and (ii) certain other foreign entities, unless they certify certain information regarding their direct and indirect U.S. owners. To avoid withholding, foreign financial institutions will need to enter into agreements with the IRS that state that they will provide the IRS information, including the name, address and taxpayer identification number of direct and indirect U.S. account holders, comply with due diligence procedures with respect to the identification of U.S. accounts, report to the IRS certain information with respect to U.S. accounts maintained, agree to withhold tax on certain payments made to non-compliant foreign financial institutions or to account holders who fail to provide the required information, and determine certain other information as to their account holders. Other foreign entities will need to provide the name, address, and taxpayer identification number of each substantial U.S. owner or certifications of no substantial U.S. ownership unless certain exceptions apply.

Dividends, interest and capital gains received by the Fund with respect to non-U.S. securities may give rise to withholding and other taxes imposed by non-U.S. countries. Tax conventions between certain countries and the United States may reduce or eliminate such taxes.

If you are a resident or a citizen of the United States, by law, back-up withholding will apply to your distributions and proceeds if you have not provided a taxpayer identification number or social security number and made other required certifications.

Taxes When Shares are Sold. Currently, any capital gain or loss realized upon a sale of Fund shares is generally treated as a long-term gain or loss if the shares have been held for more than one year. Any capital gain or loss realized upon a sale of Fund shares held for one year or less is generally treated as short-term gain or loss, except that any capital loss on the sale of shares held for six months or less is treated as long-term capital loss to the extent that capital gain dividends were paid with respect to such shares. Beginning in 2013, any such capital gains, including from sales of Fund shares or from capital gain dividends, will be included in “net investment income” for purposes of the 3.8% U.S. federal Medicare contribution tax mentioned above.

The foregoing discussion summarizes some of the consequences under current U.S. federal tax law of an investment in the Fund. It is not a substitute for personal tax advice. You may also be subject to state and local taxation on Fund distributions and sales of shares. Consult your personal tax adviser about the potential tax consequences of an investment in shares of the Fund under all applicable tax laws.

Creations and Redemptions. Prior to trading in the secondary market, shares of the Fund are “created” at NAV by market makers, large investors and institutions only in block-size Creation Units of 50,000 shares or multiples thereof. Each “creator” or “Authorized Participant” enters into an authorized participant agreement with the Fund’s distributor, SEI Investments Distribution Co. (the “Distributor”). Only an Authorized Participant may create or redeem Creation Units directly with the Fund. A creation transaction, which is subject to acceptance by the transfer agent, generally

takes place when an Authorized Participant deposits into the Fund a designated portfolio of securities and a specified amount of cash approximating the holdings of the Fund in exchange for a specified number of Creation Units. To the extent practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund.

Similarly, shares can be redeemed only in Creation Units, generally for a designated portfolio of securities and a specified amount of cash held by the Fund (“Fund Securities”). Except when aggregated in Creation Units, shares are not redeemable by the Fund. The prices at which creations and redemptions occur are based on the next calculation of NAV after an order is received in a form described in the authorized participant agreement.

The Fund intends to comply with the U.S. federal securities laws in accepting securities for deposit and satisfying redemptions with redemption securities by, among other means, assuring that any securities accepted for deposit and any securities used to satisfy redemption requests will be sold in transactions that would be exempt from registration under the Securities Act of 1933, as amended (the “1933 Act”). Further, an Authorized Participant that is not a “qualified institutional buyer,” as such term is defined under Rule 144A of the 1933 Act, will not be able to receive Fund Securities that are restricted securities eligible for resale under Rule 144A.

Creations and redemptions must be made through a firm that is either a member of the Continuous Net Settlement System of the National Securities Clearing Corporation or a DTC participant and has executed an agreement with the Distributor with respect to creations and redemptions of Creation Unit aggregations. Information about the procedures regarding creation and redemption of Creation Units (including the cut-off times for receipt of creation and redemption orders) is included in the Fund’s SAI.

Because new shares may be created and issued on an ongoing basis, at any point during the life of the Fund a “distribution,” as such term is used in the 1933 Act, may be occurring. Broker-dealers and other persons are cautioned that some activities on their part may, depending on the circumstances, result in their being deemed participants in a distribution in a manner that could render them statutory underwriters and subject to the prospectus delivery and liability provisions of the 1933 Act. Any determination of whether one is an underwriter must take into account all the relevant facts and circumstances of each particular case.

Broker-dealers should also note that dealers who are not “underwriters” but are participating in a distribution (as contrasted to ordinary secondary transactions), and thus dealing with shares that are part of an “unsold allotment” within the meaning of Section 4(3)(C) of the 1933 Act, would be unable to take advantage of the prospectus delivery exemption provided by Section 4(3) of the 1933 Act. For delivery of prospectuses to exchange members, the prospectus delivery mechanism of Rule 153 under the 1933 Act is available only with respect to transactions on a national securities exchange.

Costs Associated with Creations and Redemptions. Authorized Participants are charged standard creation and redemption transaction fees to offset transfer and other transaction costs associated with the issuance and redemption of Creation

Units. The standard creation and redemption transaction fees are set forth in the table below. The standard creation transaction fee is charged to the Authorized Participant on the day such Authorized Participant creates a Creation Unit, and is the same regardless of the number of Creation Units purchased by the Authorized Participant on the applicable business day. Similarly, the standard redemption transaction fee is charged to the Authorized Participant on the day such Authorized Participant redeems a Creation Unit, and is the same regardless of the number of Creation Units redeemed by the Authorized Participant on the applicable business day. Creations and redemptions for cash (when cash creations and redemptions (in whole or in part) are available or specified) are also subject to an additional charge (up to the maximum amounts shown in the table below). This charge is intended to compensate for brokerage, tax, foreign exchange, execution, market impact and other costs and expenses related to cash transactions. Investors who use the services of a broker or other financial intermediary may pay fees for such services.

The following table shows, as of September 30, 2011, the approximate value of one Creation Unit, standard fees and maximum additional charges for creations and redemptions (as described above):

Householding. Householding is an option available to certain Fund investors. Householding is a method of delivery, based on the preference of the individual investor, in which a single copy of certain shareholder documents can be delivered to investors who share the same address, even if their accounts are registered under different names. Please contact your broker-dealer if you are interested in enrolling in householding and receiving a single copy of prospectuses and other shareholder documents, or if you are currently enrolled in householding and wish to change your householding status.

Distribution

The Distributor distributes Creation Units for the Fund on an agency basis. The Distributor does not maintain a secondary market in shares of the Fund. The Distributor has no role in determining the policies of the Fund or the securities that are purchased or sold by the Fund. The Distributor’s principal address is One Freedom Valley Drive, Oaks, PA 19456.

In addition, BFA or its Affiliates make payments to broker-dealers, banks or other financial intermediaries (together, “intermediaries”) related to marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems, or their making shares of the Fund and

certain other iShares funds available to their customers. Such payments, which may be significant to the intermediary, are not made by the Fund. Rather, such payments are made by BFA or its Affiliates from their own resources, which come directly or indirectly in part from fees paid by the iShares funds complex. Payments of this type are sometimes referred to as revenue-sharing payments. A financial intermediary may make decisions about which investment options it recommends or makes available, or the level of services provided, to its customers based on the revenue-sharing payments it is eligible to receive. Therefore, such payments to an intermediary create conflicts of interest between the intermediary and its customers and may cause the intermediary to recommend the Fund or other iShares funds over another investment. More information regarding these payments is contained in the Fund’s SAI. Please contact your salesperson or other investment professional for more information regarding any such payments his or her firm may receive from BFA or its Affiliates.

Financial Highlights

The financial highlights table is intended to help investors understand the Fund’s financial performance for the past five years. Certain information reflects financial results for a single share of the Fund. The total returns in the table represent the rate that an investor would have earned (or lost) on an investment in the Fund, assuming reinvestment of all dividends and distributions. This information has been audited by PricewaterhouseCoopers LLP, whose report is included, along with the Fund’s financial statements, in the Fund’s Annual Report (available upon request).

Supplemental Information

I. Premium/Discount Information

The table that follows presents information about the differences between the daily market price on secondary markets for shares of the Fund and the Fund’s NAV. NAV is the price at which the Fund issues and redeems shares. It is calculated in accordance with the standard formula for valuing mutual fund shares. The price used to calculate market returns (“Market Price”) of the Fund generally is determined using the midpoint between the highest bid and the lowest offer on the primary securities exchange on which shares of the Fund are listed for trading, as of the time that the Fund’s NAV is calculated. The Fund’s Market Price may be at, above or below its NAV. The NAV of the Fund will fluctuate with changes in the value of its portfolio holdings. The Market Price of the Fund will fluctuate in accordance with changes in its NAV, as well as market supply and demand.

Premiums or discounts are the differences (expressed as a percentage) between the NAV and Market Price of the Fund on a given day, generally at the time the NAV is calculated. A premium is the amount that the Fund is trading above the reported NAV, expressed as a percentage of the NAV. A discount is the amount that the Fund is trading below the reported NAV, expressed as a percentage of the NAV.

The following information shows the frequency of distributions of premiums and discounts for the Fund for each full calendar quarter of 2010 through September 30, 2011.

Each line in the table shows the number of trading days in which the Fund traded within the premium/discount range indicated. The number of trading days in each premium/discount range is also shown as a percentage of the total number of trading days in the period covered by the table. All data presented here represents past performance, which cannot be used to predict future results.

Premium/Discount Range
Number of Days
Percentage of Total Days
Between 0.5% and -0.5% 440 99.77%
Less than -0.5% 1 0.23
   441 100.00%

II. Total Return Information

The tables that follow present information about the total returns of the Fund and the Underlying Index as of the fiscal year ended July 31, 2011.

“Average Annual Total Returns” represent the average annual change in value of an investment over the periods indicated. “Cumulative Total Returns” represent the total change in value of an investment over the periods indicated.

The Fund’s NAV is the value of one share of the Fund as calculated in accordance with the standard formula for valuing mutual fund shares. The NAV return is based on the NAV of the Fund and the market return is based on the Market Price of the Fund. Market Price is determined by using the midpoint between the highest bid and the lowest offer on the primary stock exchange on which shares of the Fund are listed for trading, as of the time that the Fund’s NAV is calculated. Market and NAV returns assume that dividends and capital gain distributions have been reinvested in the Fund at Market Price and NAV, respectively.

An index is a statistical composite that tracks a specified financial market or sector. Unlike the Fund, the Underlying Index does not actually hold a portfolio of securities and therefore does not incur the expenses incurred by the Fund. These expenses negatively impact the performance of the Fund. Also, market returns do not include brokerage commissions that may be payable on secondary market transactions. If brokerage commissions were included, market returns would be lower. The returns shown in the following tables do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption or sale of Fund shares. The investment return and principal value of shares of the Fund will vary with changes in market conditions. Shares of the Fund may be worth more or less than their original cost when they are redeemed or sold in the market. The Fund’s past performance is no guarantee of future results.

Fund Overview

iSHARES® S&P NORTH AMERICAN TECHNOLOGY-MULTIMEDIA NETWORKING INDEX FUND

Ticker: IGN Stock Exchange: NYSE Arca

Investment Objective

The iShares S&P North American Technology-Multimedia Networking Index FundTM (the “Fund”) seeks investment results that correspond generally to the price and yield performance, before fees and expenses, of the S&P North American Technology Multimedia Networking IndexTM (the “Underlying Index”).

Fees and Expenses

The following table describes the fees and expenses that you will incur if you own shares of the Fund. The investment advisory agreement between iShares Trust (the “Trust”) and BlackRock Fund Advisors (“BFA”) (the “Investment Advisory Agreement”) provides that BFA will pay all operating expenses of the Fund, except interest expenses, taxes, brokerage expenses, future distribution fees or expenses, and extraordinary expenses.

You may also incur usual and customary brokerage commissions when buying or selling shares of the Fund, which are not reflected in the example that follows:

Example. This Example is intended to help you compare the cost of owning shares of the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

Portfolio Turnover. The Fund may pay transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 28% of the average value of its portfolio.

Principal Investment Strategies

The Underlying Index measures the performance of U.S.-traded stocks of communication equipment companies in the U.S. and Canada. The Underlying Index includes companies that are producers of telecommunication, data networking and wireless equipment.

BFA uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to “beat” the index it tracks and does not seek temporary defensive positions when markets decline or appear overvalued.

Indexing may eliminate the chance that the Fund will substantially outperform the Underlying Index but also may reduce some of the risks of active management, such as poor security selection. Indexing seeks to achieve lower costs and better after-tax performance by keeping portfolio turnover low in comparison to actively managed investment companies.

BFA uses a representative sampling indexing strategy to manage the Fund. “Representative sampling” is an indexing strategy that involves investing in a representative sample of securities that collectively has an investment profile similar to the Underlying Index. The securities selected are expected to have, in the aggregate, investment characteristics (based on factors such as market capitalization and industry weightings), fundamental characteristics (such as return variability and yield) and liquidity measures similar to those of the Underlying Index. The Fund may or may not hold all of the securities in the Underlying Index.

The Fund generally invests at least 90% of its assets in securities of the Underlying Index and in depositary receipts representing securities of the Underlying Index. The Fund may invest the remainder of its assets in securities not included in the Underlying Index, but which BFA believes will help the Fund track the Underlying Index and in other investments including futures contracts, options on futures contracts, options and swaps as well as cash and cash equivalents, including shares of money market funds advised by BFA or its affiliates.

The Fund may lend securities representing up to one-third of the value of the Fund’s total assets (including the value of the collateral received).

The Underlying Index is sponsored by an organization (the “Index Provider”) that is independent of the Fund and BFA. The Index Provider determines the composition and relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index. The Fund’s Index Provider is Standard &

Poor’s Financial Services LLC (a subsidiary of The McGraw-Hill Companies) (“S&P”).

Industry Concentration Policy. The Fund will concentrate its investments (i.e., hold 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. For purposes of this limitation, securities of the U.S. government (including its agencies and instrumentalities) and repurchase agreements collateralized by U.S. government securities are not considered to be issued by members of any industry.

Summary of Principal Risks

As with any investment, you could lose all or part of your investment in the Fund, and the Fund’s performance could trail that of other investments. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund’s net asset value per share (“NAV”), trading price, yield, total return and ability to meet its investment objective.

Asset Class Risk. Securities in the Underlying Index or in the Fund’s portfolio may underperform in comparison to the general securities markets or other asset classes.

Concentration Risk. To the extent that the Fund’s investments are concentrated in a particular issuer, region, country, market, industry or asset class, the Fund may be susceptible to loss due to adverse occurrences affecting that issuer, region, country, market, industry or asset class.

Equity Securities Risk. Equity securities are subject to changes in value and their values may be more volatile than other asset classes.

Issuer Risk. Fund performance depends on the performance of individual securities to which the Fund has exposure. Changes to the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA’s investment management strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares, losses from trading in secondary markets, periods of high volatility and disruption in the creation/redemption process of the Fund. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV.

Non-Diversification Risk. The Fund may invest a large percentage of its assets in securities issued by or representing a small number of issuers. As a result, the Fund’s performance may depend on the performance of a small number of issuers.

Passive Investment Risk. The Fund is not actively managed and BFA does not attempt to take defensive positions under any market conditions, including declining markets.

Securities Lending Risk. The Fund may engage in securities lending. Securities

S-3   


Table Of Contents



lending involves the risk that the Fund may lose money because the borrower of the Fund’s loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Technology Sector Risk. Technology companies may have limited product lines, markets, financial resources or personnel. Technology companies typically face intense competition and potentially rapid product obsolescence. They are also heavily dependent on intellectual property rights and may be adversely affected by loss or impairment of those rights.

Telecommunications Sector Risk. Companies in the telecommunications sector may be affected by industry competition, substantial capital requirements, government regulation and obsolescence of telecommunications products and services due to technological advancement.

Tracking Error Risk. The performance of the Fund may diverge from that of the Underlying Index. Because the Fund employs a representative sampling strategy, the Fund may experience tracking error to a greater extent than a fund that seeks to replicate an index.

Fund returns after taxes on distributions and sale of Fund shares are calculated assuming that an investor has sufficient capital gains of the same character from other investments to offset any capital losses from the sale of Fund shares. As a result, Fund returns after taxes on distributions and sale of Fund shares may exceed Fund returns before taxes and/or returns after taxes on distributions.

Management

Investment Adviser. BlackRock Fund Advisors.

Portfolio Managers. Rene Casis, Diane Hsiung and Greg Savage (the “Portfolio Managers”) are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager supervises a portfolio management team. Mr. Casis, Ms. Hsiung and Mr. Savage have been Portfolio Managers of the Fund since 2010, 2008 and 2008, respectively.

Purchase and Sale of Fund Shares

The Fund is an exchange-traded fund (commonly referred to as an “ETF”). Individual Fund shares may only be purchased and sold on a national securities exchange through a broker-dealer. The price of Fund shares is based on market price, and because ETF shares trade at market prices rather than NAV, shares may trade at a price greater than NAV (a premium) or less than NAV (a discount). The Fund will only issue or redeem shares that have been aggregated into blocks of 50,000 shares or multiples thereof (“Creation Units”) to authorized participants who have entered into agreements with the Fund’s distributor. The Fund generally will issue or redeem Creation Units in return for a designated portfolio of securities (and an amount of cash) that the Fund specifies each day.

Tax Information

The Fund intends to make distributions that may be taxable to you as ordinary income or capital gains, unless you are investing through a tax-deferred arrangement such as a 401(k) plan or an IRA.

Payments to Broker-Dealers and other Financial Intermediaries

If you purchase shares of the Fund through a broker-dealer or other financial intermediary (such as a bank), BFA or other related companies may pay the intermediary for marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems or other services related to the sale or promotion of the Fund. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.

More Information About the Fund

This Prospectus contains important information about investing in the Fund. Please read this Prospectus carefully before you make any investment decisions. Additional information regarding the Fund is available at www.iShares.com.

BFA is the investment adviser to the Fund. Shares of the Fund are listed for trading on NYSE Arca, Inc. (“NYSE Arca”). The market price for a share of the Fund may be different from the Fund’s most recent NAV.

ETFs are funds that trade like other publicly-traded securities. The Fund is designed to track an index. Similar to shares of an index mutual fund, each share of the Fund represents a partial ownership in an underlying portfolio of securities intended to track a market index. Unlike shares of a mutual fund, which can be bought and redeemed from the issuing fund by all shareholders at a price based on NAV, shares of the Fund may be purchased or redeemed directly from the Fund at NAV solely by authorized participants. Also unlike shares of a mutual fund, shares of the Fund are listed on a national securities exchange and trade in the secondary market at market prices that change throughout the day.

The Fund invests in a particular segment of the securities markets and seeks to track the performance of a securities index that generally is not representative of the market as a whole. The Fund is designed to be used as part of broader asset allocation strategies. Accordingly, an investment in the Fund should not constitute a complete investment program.

An index is a theoretical financial calculation while the Fund is an actual investment portfolio. The performance of the Fund and the Underlying Index may vary due to transaction costs, non-U.S. currency valuations, asset valuations, corporate actions (such as mergers and spin-offs), timing variances and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions (such as diversification requirements) that apply to the Fund but not to the Underlying Index or to the use of representative sampling. “Tracking error” is the difference between the performance (return) of the Fund’s portfolio and that of the Underlying Index. BFA expects that, over time, the Fund’s tracking error will not exceed 5%. Because the Fund uses a representative sampling indexing strategy, it can be expected to have a larger tracking error than if it used a replication indexing strategy. “Replication” is an indexing strategy in which a fund invests in substantially all of the securities in its underlying index in approximately the same proportions as in the underlying index.

An investment in the Fund is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, BFA or any of its affiliates.

The Fund’s investment objective and the Underlying Index may be changed without shareholder approval.

A Further Discussion of Principal Risks

The Fund is subject to various risks, including the principal risks noted below, any of which may adversely affect the Fund’s NAV, trading price, yield, total return and ability to meet its investment objective. You could lose all or part of your investment in the Fund, and the Fund could underperform other investments.

Asset Class Risk. The securities in the Underlying Index or in the Fund’s portfolio may underperform the returns of other securities or indexes that track other industries, groups of industries, markets, asset classes or sectors. Various types of securities or indexes tend to experience cycles of outperformance and underperformance in comparison to the general securities markets.

Concentration Risk. To the extent that the Fund’s portfolio reflects the Underlying Index’s concentration in the securities of a particular issuer or issuers in a particular country, group of countries, region, market, industry, group of industries, sector or asset class, the Fund may be adversely affected by the performance of those securities, may be subject to increased price volatility and may be more susceptible to adverse economic, market, political or regulatory occurrences affecting that issuer, country, group of countries, region, market, industry, group of industries, sector or asset class.

Equity Securities Risk. The Fund invests in equity securities, which are subject to changes in value that may be attributable to market perception of a particular issuer or to general stock market fluctuations that affect all issuers. Investments in equity securities may be more volatile than investments in other asset classes.

Issuer Risk. The performance of the Fund depends on the performance of individual securities to which the Fund has exposure. Any issuer of these securities may perform poorly, causing the value of its securities to decline. Poor performance may be caused by poor management decisions, competitive pressures, changes in technology, expiration of patent protection, disruptions in supply, labor problems or shortages, corporate restructurings, fraudulent disclosures or other factors. Issuers may, in times of distress or at their own discretion, decide to reduce or eliminate dividends, which may also cause their stock prices to decline.

Management Risk. The Fund may not fully replicate the Underlying Index and may hold securities not included in the Underlying Index. As a result, the Fund is subject to the risk that BFA’s investment management strategy, the implementation of which is subject to a number of constraints, may not produce the intended results.

Market Risk. The Fund could lose money due to short-term market movements and over longer periods during market downturns. Securities may decline in value due to factors affecting securities markets generally or particular industries represented in the markets. The value of a security may decline due to general market conditions, economic trends or events that are not specifically related to the issuer of the security or to factors that affect a particular industry or industries. During a general downturn in the securities markets, multiple asset classes may be negatively affected.

Market Trading Risk

Absence of Active Market. Although shares of the Fund are listed for trading on one or more stock exchanges, there can be no assurance that an active trading market for such shares will develop or be maintained.

Risk of Secondary Listings. The Fund’s shares may be listed or traded on U.S. and non-U.S. stock exchanges other than the U.S. stock exchange where the Fund’s primary listing is maintained. There can be no assurance that the Fund’s shares will continue to trade on any such stock exchange or in any market or that the Fund’s shares will continue to meet the requirements for listing or trading on any exchange or in any market. The Fund’s shares may be less actively traded in certain markets than others, and investors are subject to the execution and settlement risks and market standards of the market where they or their broker direct their trades for execution. Certain information available to investors who trade Fund shares on a U.S. stock exchange during regular U.S. market hours may not be available to investors who trade in other markets, which may result in secondary market prices in such markets being less efficient.

Secondary Market Trading Risk. Shares of the Fund may trade in the secondary market at times when the Fund does not accept orders to purchase or redeem shares. At such times, shares may trade in the secondary market with more significant premiums or discounts than might be experienced at times when the Fund accepts purchase and redemption orders.

Secondary market trading in Fund shares may be halted by a stock exchange because of market conditions or other reasons. In addition, trading in Fund shares on a stock exchange or in any market may be subject to trading halts caused by extraordinary market volatility pursuant to “circuit breaker” rules on the stock exchange or market. There can be no assurance that the requirements necessary to maintain the listing or trading of Fund shares will continue to be met or will remain unchanged.

Shares of the Fund May Trade at Prices Other Than NAV. Shares of the Fund trade on stock exchanges at prices at, above or below their most recent NAV. The NAV of the Fund is calculated at the end of each business day and fluctuates with changes in the market value of the Fund’s holdings since the most recent calculation. The trading prices of the Fund’s shares fluctuate continuously throughout trading hours based on market supply and demand rather than NAV. The trading prices of the Fund’s shares may deviate significantly from NAV during periods of market volatility. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV. However, because shares can be created and redeemed in Creation Units at NAV (unlike shares of many closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their NAVs), BFA believes that large discounts or premiums to the NAV of the Fund are not likely to be sustained over the long-term. While the creation/redemption feature is designed to make it likely that the Fund’s shares normally will trade on stock exchanges at prices close to the Fund’s next calculated NAV, exchange prices are not expected to correlate exactly with the Fund’s NAV due to timing reasons as well as market supply and demand factors. In addition, disruptions to creations and

redemptions or extreme market volatility may result in trading prices for shares of the Fund that differ significantly from its NAV.

Costs of Buying or Selling Fund Shares. Buying or selling Fund shares on an exchange involves two types of costs that apply to all securities transactions. When buying or selling shares of the Fund through a broker, you will likely incur a brokerage commission or other charges imposed by brokers as determined by that broker. In addition, you may incur the cost of the “spread” – that is, the difference between what investors are willing to pay for Fund shares (the “bid” price) and the price at which they are willing to sell Fund shares (the “ask” price). Because of the costs inherent in buying or selling Fund shares, frequent trading may detract significantly from investment results and an investment in Fund shares may not be advisable for investors who anticipate regularly making small investments.

Non-Diversification Risk. The Fund is classified as “non-diversified.” This means that the Fund may invest a large percentage of its assets in securities issued by or representing a small number of issuers. As a result, the Fund may be more susceptible to the risks associated with these particular issuers, or to a single economic, political or regulatory occurrence affecting these issuers.

Passive Investment Risk. The Fund is not actively managed and may be affected by a general decline in market segments related to the Underlying Index. The Fund invests in securities included in, or representative of, the Underlying Index regardless of their investment merits. BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

Securities Lending Risk. The Fund may engage in securities lending. Securities lending involves the risk that the Fund may lose money because the borrower of the Fund’s loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for the loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Technology Sector Risk. The Fund invests in technology companies, which face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Technology companies may have limited product lines, markets, financial resources or personnel. The products of technology companies may face obsolescence due to rapid technological developments and frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Companies in the technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies.

Telecommunications Sector Risk. The telecommunications sector is subject to extensive government regulation. The costs of complying with governmental regulations, delays or failure to receive required regulatory approvals, or the enactment of new adverse regulatory requirements may negatively affect the business of the telecommunications companies. Government actions around the world, specifically in the area of pre-marketing clearance of products and prices, can be

arbitrary and unpredictable. Companies in the telecommunications sector may encounter distressed cash flows due to the need to commit substantial capital to meet increasing competition, particularly in formulating new products and services using new technology. Technological innovations may make the products and services of telecommunications companies obsolete.

Tracking Error Risk. Imperfect correlation between the Fund’s portfolio securities and those in the Underlying Index, rounding of prices, changes to the Underlying Index and regulatory requirements may cause tracking error, which is the divergence of the Fund’s performance from that of the Underlying Index. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Underlying Index does not. Because the Fund employs a representative sampling strategy, the Fund may experience tracking error to a greater extent than a fund that seeks to replicate an index.

A Further Discussion of Other Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies.

Risk of Investing in Canada. The United States is Canada’s largest trading and investment partner, and the Canadian economy is significantly affected by developments in the U.S. economy. Since the implementation of the North American Free Trade Agreement (“NAFTA”) in 1994 among Canada, the United States and Mexico, total two-way merchandise trade between the United States and Canada has more than doubled. To further this relationship, the three NAFTA countries entered into the Security and Prosperity Partnership of North America in March 2005, which may further affect Canada’s dependency on the U.S. economy. Any downturn in U.S. or Mexican economic activity is likely to have an adverse impact on the Canadian economy. The Canadian economy is also dependent upon external trade with other key trading partners, specifically China and the United Kingdom. As a result, Canada is dependent on the economies of these other countries. In addition, Canada is a large supplier of natural resources (e.g., oil, natural gas and agricultural products). As a result, the Canadian economy is sensitive to fluctuations in certain commodity prices.

Management

Investment Adviser. As investment adviser, BFA has overall responsibility for the general management and administration of the Trust. BFA provides an investment program for the Fund and manages the investment of the Fund’s assets. In managing the Fund, BFA may draw upon the research and expertise of its asset management

affiliates with respect to certain portfolio securities. In seeking to achieve the Fund’s investment objective, BFA uses teams of portfolio managers, investment strategists and other investment specialists. This team approach brings together many disciplines and leverages BFA’s extensive resources.

Pursuant to the Investment Advisory Agreement between BFA and the Trust (entered into on behalf of the Fund), BFA is responsible for substantially all expenses of the Fund, except interest expenses, taxes, brokerage expenses, future distribution fees or expenses and extraordinary expenses.

For its investment advisory services to the Fund, BFA is entitled to receive a management fee from the Fund corresponding to the Fund’s allocable portion of an aggregate management fee based on the aggregate average daily net assets of the following iShares funds: iShares PHLX SOX Semiconductor Sector Index Fund, iShares S&P Global Clean Energy Index Fund, iShares S&P Global Consumer Discretionary Sector Index Fund, iShares S&P Global Consumer Staples Sector Index Fund, iShares S&P Global Energy Sector Index Fund, iShares S&P Global Financials Sector Index Fund, iShares S&P Global Healthcare Sector Index Fund, iShares S&P Global Industrials Sector Index Fund, iShares S&P Global Infrastructure Index Fund, iShares S&P Global Materials Sector Index Fund, iShares S&P Global Nuclear Energy Index Fund, iShares S&P Global Technology Sector Index Fund, iShares S&P Global Telecommunications Sector Index Fund, iShares S&P Global Timber & Forestry Index Fund, iShares S&P Global Utilities Sector Index Fund, iShares S&P North American Natural Resources Sector Index Fund, iShares S&P North American Technology Sector Index Fund, iShares S&P North American Technology-Multimedia Networking Index Fund and iShares S&P North American Technology-Software Index Fund. The aggregate management fee is calculated as follows: 0.48% per annum of the aggregate net assets less than or equal to $10.0 billion, plus 0.43% per annum of the aggregate net assets over $10.0 billion, up to and including $20.0 billion, plus 0.38% per annum of the aggregate net assets in excess of $20.0 billion. As calculated on July 31, 2011, for its investment advisory services to the Fund, BFA is entitled to receive a management fee from the Fund, based on a percentage of the Fund’s average daily net assets, at an annual rate of 0.48%.

BFA is located at 400 Howard Street, San Francisco, CA 94105. It is a wholly owned subsidiary of BTC, which in turn is indirectly wholly-owned by BlackRock, Inc. (“BlackRock”). As of September 30, 2011, BTC and its affiliates, including BFA and BlackRock, provided investment advisory services for assets in excess of $3.35 trillion. BFA, BTC, BlackRock Execution Services, BlackRock and their affiliates deal, trade and invest for their own accounts in the types of securities in which the Fund may also invest.

A discussion regarding the basis for the Trust’s Board of Trustees’ (the “Board”) approval of the Investment Advisory Agreement with BFA is available in the Fund’s annual report for the period ended July 31.

Portfolio Managers. Rene Casis, Diane Hsiung and Greg Savage are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager is responsible for various functions related to portfolio management, including, but not limited to, investing cash inflows, coordinating with members of his or her portfolio

management team to focus on certain asset classes, implementing investment strategy, researching and reviewing investment strategy and overseeing members of his or her portfolio management team that have more limited responsibilities.

Rene Casis has been employed by BFA (formerly, Barclays Global Fund Advisors (“BGFA”)) and BTC (formerly, Barclays Global Investors, N.A. (“BGI”)) as a senior portfolio manager since 2009. From 2005 to 2009, Mr. Casis was a trader at Barclays Capital. Prior to that, Mr. Casis was a portfolio manager from 2000 to 2005 for BGFA and BGI. Mr. Casis has been a Portfolio Manager of the Fund since 2010.

Diane Hsiung has been employed by BFA and BTC as a senior portfolio manager since 2007. Prior to that, Ms. Hsiung was a portfolio manager from 2002 to 2006 for BGFA and BGI. Ms. Hsiung has been a Portfolio Manager of the Fund since 2008.

Greg Savage has been employed by BFA and BTC as a senior portfolio manager since 2006. Prior to that, Mr. Savage was a portfolio manager from 2001 to 2006 for BGFA and BGI. Mr. Savage has been a Portfolio Manager of the Fund since 2008.

The Fund’s SAI provides additional information about the Portfolio Managers’ compensation, other accounts managed by the Portfolio Managers and the Portfolio Managers’ ownership (if any) of shares in the Fund.

Administrator, Custodian and Transfer Agent. State Street Bank and Trust Company (“State Street”) is the administrator, custodian and transfer agent for the Fund.

Conflicts of Interest. BFA wants you to know that there are certain entities with which BFA has relationships that may give rise to conflicts of interest, or the appearance of conflicts of interest. These entities include the following: BFA’s affiliates (including BlackRock and The PNC Financial Services Group, Inc., and each of their affiliates, directors, partners, trustees, managing members, officers and employees (collectively, the “Affiliates”)) and BlackRock’s significant shareholder, Barclays Bank PLC and its affiliates, including Barclays PLC (each, an “Entity” and together, the “Entities”).

The activities of BFA, the Affiliates and the Entities in the management of, or their interest in, their own accounts and other accounts they manage, may present conflicts of interest that could disadvantage the Fund and its shareholders. BFA and its Affiliates or the Entities provide investment management services to other funds and discretionary managed accounts that may follow an investment program similar to that of the Fund. BFA, its Affiliates and the Entities are involved worldwide with a broad spectrum of financial services and asset management activities and may engage in the ordinary course of business in activities in which their interests or the interests of their clients may conflict with those of the Fund. BFA, one or more of the Affiliates or the Entities acts, or may act, as an investor, investment banker, research provider, investment manager, financier, underwriter, advisor, market maker, trader, prime broker, lender, agent or principal, and have other direct and indirect interests, in securities, currencies and other instruments in which the Fund may directly or indirectly invest. Thus, it is likely that the Fund will have multiple business relationships with and will invest in, engage in transactions with, make voting decisions with respect

to, or obtain services from, entities for which BFA, an Affiliate or an Entity performs or seeks to perform investment banking or other services.

BFA or one or more Affiliates or Entities may engage in proprietary trading and advise accounts and funds that have investment objectives similar to those of the Fund and/or that engage in and compete for transactions in the same types of securities, currencies and other instruments as the Fund, including in securities issued by other open-end and closed-end investment management companies, including investment companies that are affiliated with the Fund and BFA, to the extent permitted under the Investment Company Act of 1940, as amended (the “1940 Act”). The trading activities of BFA, these Affiliates and Entities are carried out without reference to positions held directly or indirectly by the Fund and may result in BFA, an Affiliate or an Entity having positions that are adverse to those of the Fund.

No Affiliate or Entity is under any obligation to share any investment opportunity, idea or strategy with the Fund. As a result, an Affiliate or an Entity may compete with the Fund for appropriate investment opportunities. As a result of this and several other factors, the results of the Fund’s investment activities may differ from those of an Affiliate or an Entity and of other accounts managed by an Affiliate or an Entity, and it is possible that the Fund could sustain losses during periods in which one or more Affiliates or Entities and other accounts achieve profits on their trading for proprietary or other accounts. The opposite result is also possible.

The Fund may, from time to time, enter into transactions in which BFA or an Affiliate’s or an Entity’s clients have an interest adverse to the Fund. Furthermore, transactions undertaken by Affiliate-advised clients may adversely impact the Fund. Transactions by one or more Affiliate- or Entity-advised clients or BFA may have the effect of diluting or otherwise disadvantaging the values, prices or investment strategies of the Fund.

An Entity may maintain securities indices as part of its product offerings. Index-based funds seek to track the performance of securities indices and may use the name of the index in the fund name. Index providers, including the Entities, may be paid licensing fees for use of their indices or index names. Entities will not be obligated to license their indices to BFA and its Affiliates, and BFA and its Affiliates will not be assured that the terms of any index licensing agreement with the Entities will be as favorable as those terms offered to other index licensees.

The Fund’s activities may be limited because of regulatory restrictions applicable to one or more Affiliates or Entities, and/or their internal policies designed to comply with such restrictions. In addition, the Fund may invest in securities of companies with which an Affiliate or an Entity has or is trying to develop investment banking relationships or in which an Affiliate or an Entity has significant debt or equity investments. The Fund also may invest in securities of companies for which an Affiliate or an Entity provides or may some day provide research coverage. An Affiliate or an Entity may have business relationships with and purchase or distribute or sell services or products from or to distributors, consultants or others who recommend the Fund or who engage in transactions with or for the Fund, and may receive compensation for such services. The Fund may also make brokerage and other payments to Affiliates or Entities in connection with the Fund’s portfolio investment transactions.

Pursuant to a securities lending program approved by the Board, the Fund has retained an Affiliate of BFA to serve as the securities lending agent for the Fund to the extent that the Fund participates in the securities lending program. For these services, the lending agent may receive a fee from the Fund, including a fee based on the returns earned on the Fund’s investment of the cash received as collateral for any loaned securities. In addition, one or more Affiliates may be among the entities to which the Fund may lend its portfolio securities under the securities lending program.

The activities of BFA, the Affiliates or Entities may give rise to other conflicts of interest that could disadvantage the Fund and its shareholders. BFA has adopted policies and procedures designed to address these potential conflicts of interest. See the Fund’s SAI for further information.

Shareholder Information

Additional shareholder information, including how to buy and sell shares of the Fund, is available free of charge by calling toll-free: 1-800-iShares (1-800-474-2737) or visiting our website at www.iShares.com.

Buying and Selling Shares. Shares of the Fund may be acquired or redeemed directly from the Fund only in Creation Units or multiples thereof, as discussed in the Creations and Redemptions section of this Prospectus. Only an Authorized Participant (as defined in the Creations and Redemptions section) may engage in creation or redemption transactions directly with the Fund. Once created, shares of the Fund generally trade in the secondary market in amounts less than a Creation Unit.

Shares of the Fund are listed on a national securities exchange for trading during the trading day. Shares can be bought and sold throughout the trading day like shares of other publicly-traded companies. The Trust does not impose any minimum investment for shares of the Fund purchased on an exchange. The Fund’s shares trade under the trading symbol “IGN.”

Buying or selling Fund shares on an exchange involves two types of costs that may apply to all securities transactions. When buying or selling shares of the Fund through a broker, you will likely incur a brokerage commission or other charges determined by your broker. The commission is frequently a fixed amount and may be a significant proportional cost for investors seeking to buy or sell small amounts of shares. In addition, you may incur the cost of the “spread” – that is, any difference between the bid price and the ask price. The spread varies over time for shares of the Fund based on its trading volume and market liquidity, and is generally lower if the Fund has a lot of trading volume and market liquidity, and higher if the Fund has little trading volume and market liquidity.

The Board has adopted a policy of not monitoring for frequent purchases and redemptions of Fund shares (“frequent trading”) that appear to attempt to take advantage of a potential arbitrage opportunity presented by a lag between a change in the value of the Fund’s portfolio securities after the close of the primary markets for the Fund’s portfolio securities and the reflection of that change in the Fund’s NAV (“market timing”), because the Fund generally sells and redeems its shares directly through transactions that are in-kind and/or for cash, subject to the conditions

described below under Creations and Redemptions. The Board has not adopted a policy of monitoring for other frequent trading activity because shares of the Fund are listed for trading on a national securities exchange.

The national securities exchange on which the Fund’s shares are listed is open for trading Monday through Friday and is closed on weekends and the following holidays: New Year’s Day, Martin Luther King, Jr. Day, Presidents’ Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day. The Fund’s primary listing exchange is NYSE Arca.

Section 12(d)(1) of the 1940 Act restricts investments by investment companies in the securities of other investment companies. Registered investment companies are permitted to invest in the Fund beyond the limits set forth in Section 12(d)(1), subject to certain terms and conditions set forth in SEC rules or in an SEC exemptive order issued to the Trust. In order for a registered investment company to invest in shares of the Fund beyond the limitations of Section 12(d)(1) pursuant to the exemptive relief obtained by the Trust, the registered investment company must enter into an agreement with the Trust.

Book Entry. Shares of the Fund are held in book-entry form, which means that no stock certificates are issued. The Depository Trust Company (“DTC”) or its nominee is the record owner of all outstanding shares of the Fund and is recognized as the owner of all shares for all purposes.

Investors owning shares of the Fund are beneficial owners as shown on the records of DTC or its participants. DTC serves as the securities depository for shares of the Fund. DTC participants include securities brokers and dealers, banks, trust companies, clearing corporations and other institutions that directly or indirectly maintain a custodial relationship with DTC. As a beneficial owner of shares, you are not entitled to receive physical delivery of stock certificates or to have shares registered in your name, and you are not considered a registered owner of shares. Therefore, to exercise any right as an owner of shares, you must rely upon the procedures of DTC and its participants. These procedures are the same as those that apply to any other securities that you hold in book-entry or “street name” form.

Share Prices. The trading prices of the Fund’s shares in the secondary market generally differ from the Fund’s daily NAV and are affected by market forces such as supply and demand, economic conditions and other factors. Information regarding the intraday value of shares of the Fund, also known as the “indicative optimized portfolio value” (“IOPV”), is disseminated every 15 seconds throughout the trading day by the national securities exchange on which the Fund’s shares are listed or by market data vendors or other information providers. The IOPV is based on the current market value of the securities and/or cash required to be deposited in exchange for a Creation Unit. The IOPV does not necessarily reflect the precise composition of the current portfolio of securities held by the Fund at a particular point in time or the best possible valuation of the current portfolio. Therefore, the IOPV should not be viewed as a “real-time” update of the Fund’s NAV, which is computed only once a day. The IOPV is generally determined by using both current market quotations and/or price quotations obtained from broker-dealers that may trade in the portfolio securities held by the Fund. The quotations of certain Fund holdings may not be updated during U.S. trading hours if

such holdings do not trade in the United States. The Fund is not involved in, or responsible for, the calculation or dissemination of the IOPV and makes no representation or warranty as to its accuracy.

Determination of Net Asset Value. The NAV of the Fund normally is determined once daily Monday through Friday, generally as of the regularly scheduled close of business of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m., Eastern time) on each day that the NYSE is open for trading, based on prices at the time of closing provided that (a) any Fund assets or liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers (as detailed below) and (b) U.S. fixed income assets may be valued as of the announced closing time for trading in fixed income instruments in a particular market or exchange. The NAV of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets held by the Fund, and its liabilities, are determined pursuant to valuation policies and procedures approved by the Board. The Fund’s assets and liabilities are valued primarily on the basis of market quotations.

Equity investments are valued at market value, which is generally determined using the last reported official closing price or last trading price on the exchange or market on which the security is primarily traded at the time of valuation.

Generally, trading in foreign securities, U.S. government securities, money market instruments and certain fixed-income securities is substantially completed each day at various times prior to the close of business on the NYSE. The values of such securities used in computing the NAV of the Fund are determined as of such times.

When market quotations are not readily available or are believed by BFA to be unreliable, the Fund’s investments are valued at fair value. Fair value determinations are made by BFA in accordance with policies and procedures approved by the Fund’s Board. BFA may conclude that a market quotation is not readily available or is unreliable if a security or other asset or liability does not have a price source due to its lack of liquidity, if a market quotation differs significantly from recent price quotations or otherwise no longer appears to reflect fair value, where the security or other asset or liability is thinly traded, or where there is a significant event subsequent to the most recent market quotation. A “significant event” is an event that, in the judgment of BFA, is likely to cause a material change to the closing market price of the asset or liability held by the Fund. Foreign securities whose values are affected by volatility that occurs in U.S. markets on a trading day after the close of foreign securities markets may be fair valued.

Fair value represents a good faith approximation of the value of an asset or liability. The fair value of an asset or liability held by the Fund is the amount the Fund might reasonably expect to receive from the current sale of that asset or the cost to extinguish that liability in an arm’s-length transaction. Valuing the Fund’s investments using fair value pricing will result in prices that may differ from current market valuations and that may not be the price at which those investments could have been

sold during the period in which the particular fair values were used. Use of fair value prices and certain current market valuations could result in a difference between the prices used to calculate the Fund’s NAV and the prices used by the Underlying Index, which, in turn, could result in a difference between the Fund’s performance and the performance of the Underlying Index.

Dividends and Distributions

General Policies. Dividends from net investment income, if any, generally are declared and paid quarterly by the Fund. Distributions of net realized securities gains, if any, generally are declared and paid once a year, but the Trust may make distributions on a more frequent basis for the Fund. The Trust reserves the right to declare special distributions if, in its reasonable discretion, such action is necessary or advisable to preserve its status as a regulated investment company (“RIC”) or to avoid imposition of income or excise taxes on undistributed income or realized gains.

Dividends and other distributions on shares of the Fund are distributed on a pro rata basis to beneficial owners of such shares. Dividend payments are made through DTC participants and indirect participants to beneficial owners then of record with proceeds received from the Fund.

Dividend Reinvestment Service. No dividend reinvestment service is provided by the Trust. Broker-dealers may make available the DTC book-entry Dividend Reinvestment Service for use by beneficial owners of the Fund for reinvestment of their dividend distributions. Beneficial owners should contact their broker to determine the availability and costs of the service and the details of participation therein. Brokers may require beneficial owners to adhere to specific procedures and timetables. If this service is available and used, dividend distributions of both income and realized gains will be automatically reinvested in additional whole shares of the Fund purchased in the secondary market.

Taxes. As with any investment, you should consider how your investment in shares of the Fund will be taxed. The tax information in this Prospectus is provided as general information, based on current law. You should consult your own tax professional about the tax consequences of an investment in shares of the Fund.

Unless your investment in Fund shares is made through a tax-exempt entity or tax-deferred retirement account, such as an IRA, you need to be aware of the possible tax consequences when the Fund makes distributions or you sell Fund shares.

Taxes on Distributions. Distributions from the Fund’s net investment income (other than qualified dividend income), including distributions of income from securities lending and distributions out of the Fund’s net short-term capital gains, if any, are taxable to you as ordinary income. Distributions by the Fund of net long-term capital gains in excess of net short-term capital losses (capital gain dividends) are taxable to you as long-term capital gains, generally at a 15% tax rate (0% at certain income levels), regardless of how long you have held the Fund’s shares. Distributions by the Fund that qualify as qualified dividend income are taxable to you at long-term capital gain rates for taxable years beginning on or before December 31, 2012. The 15% and 0% tax rates expire for taxable years beginning after December 31, 2012. Maximum long-term capital gain income tax rates are scheduled to rise to 20% in 2013.

Beginning in 2013, a 3.8% U.S. federal Medicare contribution tax will be imposed on “net investment income,” including interest, dividends, and capital gains, of U.S. individuals with income exceeding $200,000 (or $250,000 if married and filing jointly), and of estates and trusts.

Dividends will be qualified dividend income to you if they are attributable to qualified dividend income received by the Fund. Generally, qualified dividend income includes dividend income from taxable U.S. corporations and qualified non-U.S. corporations, provided that the Fund satisfies certain holding period requirements in respect of the stock of such corporations and has not hedged its position in the stock in certain ways. Substitute dividends received by the Fund with respect to dividends paid on securities lent out will not be qualified dividend income. For this purpose, a qualified non-U.S. corporation means any non-U.S. corporation that is eligible for benefits under a comprehensive income tax treaty with the United States, which includes an exchange of information program or if the stock with respect to which the dividend was paid is readily tradable on an established United States securities market. The term excludes a corporation that is a passive foreign investment company.

Dividends received by the Fund from a real estate investment trust (“REIT”) or another RIC generally are qualified dividend income only to the extent the dividend distributions are made out of qualified dividend income received by such REIT or RIC. It is expected that dividends received by the Fund from a REIT and distributed to a shareholder generally will be taxable to the shareholder as ordinary income.

For a dividend to be treated as qualified dividend income, the dividend must be received with respect to a share of stock held without being hedged by the Fund, and with respect to a share of the Fund held without being hedged by you, for 61 days during the 121-day period beginning at the date which is 60 days before the date on which such share becomes ex-dividend with respect to such dividend or, in the case of certain preferred stock, 91 days during the 181-day period beginning 90 days before such date.

If your Fund shares are loaned out pursuant to a securities lending arrangement, you may lose the ability to use foreign tax credits passed through by the Fund or to treat Fund dividends paid while the shares are held by the borrower as qualified dividend income.

In general, your distributions are subject to U.S. federal income tax for the year when they are paid. Certain distributions paid in January, however, may be treated as paid on December 31 of the prior year.

If the Fund’s distributions exceed current and accumulated earnings and profits, all or a portion of the distributions made in the taxable year may be recharacterized as a return of capital to shareholders. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and result in a higher capital gain or lower capital loss when those shares on which the distribution was received are sold. Once a shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain, if the shareholder holds shares of the Fund as capital assets.

If you are neither a resident nor a citizen of the United States or if you are a non-U.S. entity, the Fund’s ordinary income dividends (which include distributions of net short-term capital gains) will generally be subject to a 30% U.S. withholding tax, unless a lower treaty rate applies, provided that withholding tax will generally not apply to any gain or income realized by a non-U.S. shareholder in respect of any distributions of long-term capital gains or upon the sale or other disposition of shares of the Fund.

A 30% withholding tax will be imposed on dividends paid after December 31, 2013, and redemption proceeds paid after December 31, 2014, to (i) foreign financial institutions including non-U.S. investment funds unless they agree to collect and disclose to the Internal Revenue Service (“IRS”) information regarding their direct and indirect U.S. account holders and (ii) certain other foreign entities, unless they certify certain information regarding their direct and indirect U.S. owners. To avoid withholding, foreign financial institutions will need to enter into agreements with the IRS that state that they will provide the IRS information, including the name, address and taxpayer identification number of direct and indirect U.S. account holders, comply with due diligence procedures with respect to the identification of U.S. accounts, report to the IRS certain information with respect to U.S. accounts maintained, agree to withhold tax on certain payments made to non-compliant foreign financial institutions or to account holders who fail to provide the required information, and determine certain other information as to their account holders. Other foreign entities will need to provide the name, address, and taxpayer identification number of each substantial U.S. owner or certifications of no substantial U.S. ownership unless certain exceptions apply.

Dividends, interest and capital gains received by the Fund with respect to non-U.S. securities may give rise to withholding and other taxes imposed by non-U.S. countries. Tax conventions between certain countries and the United States may reduce or eliminate such taxes.

If you are a resident or a citizen of the United States, by law, back-up withholding will apply to your distributions and proceeds if you have not provided a taxpayer identification number or social security number and made other required certifications.

Taxes When Shares are Sold. Currently, any capital gain or loss realized upon a sale of Fund shares is generally treated as a long-term gain or loss if the shares have been held for more than one year. Any capital gain or loss realized upon a sale of Fund shares held for one year or less is generally treated as short-term gain or loss, except that any capital loss on the sale of shares held for six months or less is treated as long-term capital loss to the extent that capital gain dividends were paid with respect to such shares. Beginning in 2013, any such capital gains, including from sales of Fund shares or from capital gain dividends, will be included in “net investment income” for purposes of the 3.8% U.S. federal Medicare contribution tax mentioned above.

The foregoing discussion summarizes some of the consequences under current U.S. federal tax law of an investment in the Fund. It is not a substitute for personal tax advice. You may also be subject to state and local taxation on Fund distributions and sales of shares. Consult your personal tax adviser about the potential tax consequences of an investment in shares of the Fund under all applicable tax laws.

Creations and Redemptions. Prior to trading in the secondary market, shares of the Fund are “created” at NAV by market makers, large investors and institutions only in block-size Creation Units of 50,000 shares or multiples thereof. Each “creator” or “Authorized Participant” enters into an authorized participant agreement with the Fund’s distributor, SEI Investments Distribution Co. (the “Distributor”). Only an Authorized Participant may create or redeem Creation Units directly with the Fund. A creation transaction, which is subject to acceptance by the transfer agent, generally takes place when an Authorized Participant deposits into the Fund a designated portfolio of securities and a specified amount of cash approximating the holdings of the Fund in exchange for a specified number of Creation Units. To the extent practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund.

Similarly, shares can be redeemed only in Creation Units, generally for a designated portfolio of securities and a specified amount of cash held by the Fund (“Fund Securities”). Except when aggregated in Creation Units, shares are not redeemable by the Fund. The prices at which creations and redemptions occur are based on the next calculation of NAV after an order is received in a form described in the authorized participant agreement.

The Fund intends to comply with the U.S. federal securities laws in accepting securities for deposit and satisfying redemptions with redemption securities by, among other means, assuring that any securities accepted for deposit and any securities used to satisfy redemption requests will be sold in transactions that would be exempt from registration under the Securities Act of 1933, as amended (the “1933 Act”). Further, an Authorized Participant that is not a “qualified institutional buyer,” as such term is defined under Rule 144A of the 1933 Act, will not be able to receive Fund Securities that are restricted securities eligible for resale under Rule 144A.

Creations and redemptions must be made through a firm that is either a member of the Continuous Net Settlement System of the National Securities Clearing Corporation or a DTC participant and has executed an agreement with the Distributor with respect to creations and redemptions of Creation Unit aggregations. Information about the procedures regarding creation and redemption of Creation Units (including the cut-off times for receipt of creation and redemption orders) is included in the Fund’s SAI.

Because new shares may be created and issued on an ongoing basis, at any point during the life of the Fund a “distribution,” as such term is used in the 1933 Act, may be occurring. Broker-dealers and other persons are cautioned that some activities on their part may, depending on the circumstances, result in their being deemed participants in a distribution in a manner that could render them statutory underwriters and subject to the prospectus delivery and liability provisions of the 1933 Act. Any determination of whether one is an underwriter must take into account all the relevant facts and circumstances of each particular case.

Broker-dealers should also note that dealers who are not “underwriters” but are participating in a distribution (as contrasted to ordinary secondary transactions), and thus dealing with shares that are part of an “unsold allotment” within the meaning of Section 4(3)(C) of the 1933 Act, would be unable to take advantage of the prospectus delivery exemption provided by Section 4(3) of the 1933 Act. For delivery of

prospectuses to exchange members, the prospectus delivery mechanism of Rule 153 under the 1933 Act is available only with respect to transactions on a national securities exchange.

Costs Associated with Creations and Redemptions. Authorized Participants are charged standard creation and redemption transaction fees to offset transfer and other transaction costs associated with the issuance and redemption of Creation Units. The standard creation and redemption transaction fees are set forth in the table below. The standard creation transaction fee is charged to the Authorized Participant on the day such Authorized Participant creates a Creation Unit, and is the same regardless of the number of Creation Units purchased by the Authorized Participant on the applicable business day. Similarly, the standard redemption transaction fee is charged to the Authorized Participant on the day such Authorized Participant redeems a Creation Unit, and is the same regardless of the number of Creation Units redeemed by the Authorized Participant on the applicable business day. Creations and redemptions for cash (when cash creations and redemptions (in whole or in part) are available or specified) are also subject to an additional charge (up to the maximum amounts shown in the table below). This charge is intended to compensate for brokerage, tax, foreign exchange, execution, market impact and other costs and expenses related to cash transactions. Investors who use the services of a broker or other financial intermediary may pay fees for such services.

The following table shows, as of September 30, 2011, the approximate value of one Creation Unit, standard fees and maximum additional charges for creations and redemptions (as described above):

Householding. Householding is an option available to certain Fund investors. Householding is a method of delivery, based on the preference of the individual investor, in which a single copy of certain shareholder documents can be delivered to investors who share the same address, even if their accounts are registered under different names. Please contact your broker-dealer if you are interested in enrolling in householding and receiving a single copy of prospectuses and other shareholder documents, or if you are currently enrolled in householding and wish to change your householding status.

Distribution

The Distributor distributes Creation Units for the Fund on an agency basis. The Distributor does not maintain a secondary market in shares of the Fund. The Distributor has no role in determining the policies of the Fund or the securities that are

purchased or sold by the Fund. The Distributor’s principal address is One Freedom Valley Drive, Oaks, PA 19456.

In addition, BFA or its Affiliates make payments to broker-dealers, banks or other financial intermediaries (together, “intermediaries”) related to marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems, or their making shares of the Fund and certain other iShares funds available to their customers. Such payments, which may be significant to the intermediary, are not made by the Fund. Rather, such payments are made by BFA or its Affiliates from their own resources, which come directly or indirectly in part from fees paid by the iShares funds complex. Payments of this type are sometimes referred to as revenue-sharing payments. A financial intermediary may make decisions about which investment options it recommends or makes available, or the level of services provided, to its customers based on the revenue-sharing payments it is eligible to receive. Therefore, such payments to an intermediary create conflicts of interest between the intermediary and its customers and may cause the intermediary to recommend the Fund or other iShares funds over another investment. More information regarding these payments is contained in the Fund’s SAI. Please contact your salesperson or other investment professional for more information regarding any such payments his or her firm may receive from BFA or its Affiliates.

Financial Highlights

The financial highlights table is intended to help investors understand the Fund’s financial performance for the past five years. Certain information reflects financial results for a single share of the Fund. The total returns in the table represent the rate that an investor would have earned (or lost) on an investment in the Fund, assuming reinvestment of all dividends and distributions. This information has been audited by PricewaterhouseCoopers LLP, whose report is included, along with the Fund’s financial statements, in the Fund’s Annual Report (available upon request).

Supplemental Information

I. Premium/Discount Information

The table that follows presents information about the differences between the daily market price on secondary markets for shares of the Fund and the Fund’s NAV. NAV is the price at which the Fund issues and redeems shares. It is calculated in accordance with the standard formula for valuing mutual fund shares. The price used to calculate market returns (“Market Price”) of the Fund generally is determined using the midpoint between the highest bid and the lowest offer on the primary securities exchange on which shares of the Fund are listed for trading, as of the time that the Fund’s NAV is calculated. The Fund’s Market Price may be at, above or below its NAV. The NAV of the Fund will fluctuate with changes in the value of its portfolio holdings. The Market Price of the Fund will fluctuate in accordance with changes in its NAV, as well as market supply and demand.

Premiums or discounts are the differences (expressed as a percentage) between the NAV and Market Price of the Fund on a given day, generally at the time the NAV is calculated. A premium is the amount that the Fund is trading above the reported NAV, expressed as a percentage of the NAV. A discount is the amount that the Fund is trading below the reported NAV, expressed as a percentage of the NAV.

The following information shows the frequency of distributions of premiums and discounts for the Fund for each full calendar quarter of 2010 through September 30, 2011.

Each line in the table shows the number of trading days in which the Fund traded within the premium/discount range indicated. The number of trading days in each premium/discount range is also shown as a percentage of the total number of trading days in the period covered by the table. All data presented here represents past performance, which cannot be used to predict future results.

Between 0.5% and -0.5% 440 99.77
   441 100.00%

II. Total Return Information

The tables that follow present information about the total returns of the Fund and the Underlying Index as of the fiscal year ended July 31, 2011.

“Average Annual Total Returns” represent the average annual change in value of an investment over the periods indicated. “Cumulative Total Returns” represent the total change in value of an investment over the periods indicated.

The Fund’s NAV is the value of one share of the Fund as calculated in accordance with the standard formula for valuing mutual fund shares. The NAV return is based on the NAV of the Fund and the market return is based on the Market Price of the Fund. Market Price is determined by using the midpoint between the highest bid and the lowest offer on the primary stock exchange on which shares of the Fund are listed for trading, as of the time that the Fund’s NAV is calculated. Market and NAV returns assume that dividends and capital gain distributions have been reinvested in the Fund at Market Price and NAV, respectively.

An index is a statistical composite that tracks a specified financial market or sector. Unlike the Fund, the Underlying Index does not actually hold a portfolio of securities and therefore does not incur the expenses incurred by the Fund. These expenses negatively impact the performance of the Fund. Also, market returns do not include brokerage commissions that may be payable on secondary market transactions. If brokerage commissions were included, market returns would be lower. The returns shown in the following tables do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption or sale of Fund shares. The investment return and principal value of shares of the Fund will vary with changes in market conditions. Shares of the Fund may be worth more or less than their original cost when they are redeemed or sold in the market. The Fund’s past performance is no guarantee of future results.

Fund Overview

iSHARES® S&P NORTH AMERICAN TECHNOLOGY-SOFTWARE INDEX FUND

Ticker: IGV Stock Exchange: NYSE Arca

Investment Objective

The iShares S&P North American Technology-Software Index FundTM (the “Fund”) seeks investment results that correspond generally to the price and yield performance, before fees and expenses, of the S&P North American Technology Software IndexTM (the “Underlying Index”).

Fees and Expenses

The following table describes the fees and expenses that you will incur if you own shares of the Fund. The investment advisory agreement between iShares Trust (the “Trust”) and BlackRock Fund Advisors (“BFA”) (the “Investment Advisory Agreement”) provides that BFA will pay all operating expenses of the Fund, except interest expenses, taxes, brokerage expenses, future distribution fees or expenses, and extraordinary expenses.

You may also incur usual and customary brokerage commissions when buying or selling shares of the Fund, which are not reflected in the example that follows:

Example. This Example is intended to help you compare the cost of owning shares of the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

Portfolio Turnover. The Fund may pay transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 18% of the average value of its portfolio.

Principal Investment Strategies

The Underlying Index measures the performance of U.S.-traded stocks of software-related companies in the U.S. and Canada. The Underlying Index includes companies that are producers of client/server applications, enterprise software, application software, personal computers and home entertainment software.

BFA uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to “beat” the index it tracks and does not seek temporary defensive positions when markets decline or appear overvalued.

Indexing may eliminate the chance that the Fund will substantially outperform the Underlying Index but also may reduce some of the risks of active management, such as poor security selection. Indexing seeks to achieve lower costs and better after-tax performance by keeping portfolio turnover low in comparison to actively managed investment companies.

BFA uses a representative sampling indexing strategy to manage the Fund. “Representative sampling” is an indexing strategy that involves investing in a representative sample of securities that collectively has an investment profile similar to the Underlying Index. The securities selected are expected to have, in the aggregate, investment characteristics (based on factors such as market capitalization and industry weightings), fundamental characteristics (such as return variability and yield) and liquidity measures similar to those of the Underlying Index. The Fund may or may not hold all of the securities in the Underlying Index.

The Fund generally invests at least 90% of its assets in securities of the Underlying Index and in depositary receipts representing securities of the Underlying Index. The Fund may invest the remainder of its assets in securities not included in the Underlying Index, but which BFA believes will help the Fund track the Underlying Index and in other investments including futures contracts, options on futures contracts, options and swaps as well as cash and cash equivalents, including shares of money market funds advised by BFA or its affiliates.

The Fund may lend securities representing up to one-third of the value of the Fund’s total assets (including the value of the collateral received).

The Underlying Index is sponsored by an organization (the “Index Provider”) that is independent of the Fund and BFA. The Index Provider determines the composition and relative weightings of the securities in the Underlying Index and publishes information regarding the

S-2   


Table Of Contents



market value of the Underlying Index. The Fund’s Index Provider is Standard & Poor’s Financial Services LLC (a subsidiary of The McGraw-Hill Companies) (“S&P”).

Industry Concentration Policy. The Fund will concentrate its investments (i.e., hold 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. For purposes of this limitation, securities of the U.S. government (including its agencies and instrumentalities) and repurchase agreements collateralized by U.S. government securities are not considered to be issued by members of any industry.

Summary of Principal Risks

As with any investment, you could lose all or part of your investment in the Fund, and the Fund’s performance could trail that of other investments. The Fund is subject to the principal risks noted below, any of which may adversely affect the Fund’s net asset value per share (“NAV”), trading price, yield, total return and ability to meet its investment objective.

Asset Class Risk. Securities in the Underlying Index or in the Fund’s portfolio may underperform in comparison to the general securities markets or other asset classes.

Concentration Risk. To the extent that the Fund’s investments are concentrated in a particular issuer, region, country, market, industry or asset class, the Fund may be susceptible to loss due to adverse occurrences affecting that issuer, region, country, market, industry or asset class.

Equity Securities Risk. Equity securities are subject to changes in value and their values may be more volatile than other asset classes.

Issuer Risk. Fund performance depends on the performance of individual securities to which the Fund has exposure. Changes to the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA’s investment management strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares, losses from trading in secondary markets, periods of high volatility and disruption in the creation/redemption process of the Fund. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV.

Non-Diversification Risk. The Fund may invest a large percentage of its assets in securities issued by or representing a small number of issuers. As a result, the Fund’s performance may depend on the performance of a small number of issuers.

Passive Investment Risk. The Fund is not actively managed and BFA does not attempt to take defensive positions under any market conditions, including declining markets.

Securities Lending Risk. The Fund may engage in securities lending. Securities lending involves the risk that the Fund may lose money because the borrower of the Fund’s loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Technology Sector Risk. Technology companies may have limited product lines, markets, financial resources or personnel. Technology companies typically face intense competition and potentially rapid product obsolescence. They are also heavily dependent on intellectual property rights and may be adversely affected by loss or impairment of those rights.

Tracking Error Risk. The performance of the Fund may diverge from that of the Underlying Index. Because the Fund employs a representative sampling strategy, the Fund may experience tracking error to a greater extent than a fund that seeks to replicate an index.

1 After-tax returns in the table above are calculated using the historical highest individual U.S. federal marginal income tax rates and do not reflect the impact of state or local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown, and after-tax returns shown are not relevant to tax-exempt investors or investors who hold shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts (“IRAs”). Fund returns after taxes on distributions and sale of Fund shares are calculated assuming that an investor has sufficient capital gains of the same character from other investments to offset any capital losses from the sale of Fund shares. As a result, Fund returns after taxes on distributions and sale of Fund shares may exceed Fund returns before taxes and/or returns after taxes on distributions.

Management

Investment Adviser. BlackRock Fund Advisors.

Portfolio Managers. Rene Casis, Diane Hsiung and Greg Savage (the “Portfolio Managers”) are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager supervises a portfolio management team. Mr. Casis, Ms. Hsiung and Mr. Savage have been Portfolio Managers of the Fund since 2010, 2008 and 2008, respectively.

Purchase and Sale of Fund Shares

The Fund is an exchange-traded fund (commonly referred to as an “ETF”). Individual Fund shares may only be purchased and sold on a national securities exchange through a broker-dealer. The price of Fund shares is based on market price, and because ETF shares trade at market prices rather than NAV, shares may trade at a price greater than NAV (a premium) or less than NAV (a discount). The Fund will only issue or redeem shares that have been aggregated into blocks of 50,000 shares or multiples thereof (“Creation Units”) to authorized participants who have entered into agreements with the Fund’s distributor. The Fund generally will issue or redeem Creation Units in return for a designated portfolio of securities (and an amount of cash) that the Fund specifies each day.

Tax Information

The Fund intends to make distributions that may be taxable to you as ordinary income or capital gains, unless you are investing through a tax-deferred arrangement such as a 401(k) plan or an IRA.

Payments to Broker-Dealers and other Financial Intermediaries

If you purchase shares of the Fund through a broker-dealer or other financial intermediary (such as a bank), BFA or other related companies may pay the intermediary for marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems or other services related to the sale or promotion of the Fund. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.

More Information About the Fund

This Prospectus contains important information about investing in the Fund. Please read this Prospectus carefully before you make any investment decisions. Additional information regarding the Fund is available at www.iShares.com.

BFA is the investment adviser to the Fund. Shares of the Fund are listed for trading on NYSE Arca, Inc. (“NYSE Arca”). The market price for a share of the Fund may be different from the Fund’s most recent NAV.

ETFs are funds that trade like other publicly-traded securities. The Fund is designed to track an index. Similar to shares of an index mutual fund, each share of the Fund represents a partial ownership in an underlying portfolio of securities intended to track a market index. Unlike shares of a mutual fund, which can be bought and redeemed from the issuing fund by all shareholders at a price based on NAV, shares of the Fund may be purchased or redeemed directly from the Fund at NAV solely by authorized participants. Also unlike shares of a mutual fund, shares of the Fund are listed on a national securities exchange and trade in the secondary market at market prices that change throughout the day.

The Fund invests in a particular segment of the securities markets and seeks to track the performance of a securities index that generally is not representative of the market as a whole. The Fund is designed to be used as part of broader asset allocation strategies. Accordingly, an investment in the Fund should not constitute a complete investment program.

An index is a theoretical financial calculation while the Fund is an actual investment portfolio. The performance of the Fund and the Underlying Index may vary due to transaction costs, non-U.S. currency valuations, asset valuations, corporate actions (such as mergers and spin-offs), timing variances and differences between the Fund’s portfolio and the Underlying Index resulting from legal restrictions (such as diversification requirements) that apply to the Fund but not to the Underlying Index or to the use of representative sampling. “Tracking error” is the difference between the performance (return) of the Fund’s portfolio and that of the Underlying Index. BFA expects that, over time, the Fund’s tracking error will not exceed 5%. Because the Fund uses a representative sampling indexing strategy, it can be expected to have a larger tracking error than if it used a replication indexing strategy. “Replication” is an indexing strategy in which a fund invests in substantially all of the securities in its underlying index in approximately the same proportions as in the underlying index.

An investment in the Fund is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, BFA or any of its affiliates.

The Fund’s investment objective and the Underlying Index may be changed without shareholder approval.

A Further Discussion of Principal Risks

The Fund is subject to various risks, including the principal risks noted below, any of which may adversely affect the Fund’s NAV, trading price, yield, total return and ability to meet its investment objective. You could lose all or part of your investment in the Fund, and the Fund could underperform other investments.

Asset Class Risk. The securities in the Underlying Index or in the Fund’s portfolio may underperform the returns of other securities or indexes that track other industries, groups of industries, markets, asset classes or sectors. Various types of securities or indexes tend to experience cycles of outperformance and underperformance in comparison to the general securities markets.

Concentration Risk. To the extent that the Fund’s portfolio reflects the Underlying Index’s concentration in the securities of a particular issuer or issuers in a particular country, group of countries, region, market, industry, group of industries, sector or asset class, the Fund may be adversely affected by the performance of those securities, may be subject to increased price volatility and may be more susceptible to adverse economic, market, political or regulatory occurrences affecting that issuer, country, group of countries, region, market, industry, group of industries, sector or asset class.

Equity Securities Risk. The Fund invests in equity securities, which are subject to changes in value that may be attributable to market perception of a particular issuer or to general stock market fluctuations that affect all issuers. Investments in equity securities may be more volatile than investments in other asset classes.

Issuer Risk. The performance of the Fund depends on the performance of individual securities to which the Fund has exposure. Any issuer of these securities may perform poorly, causing the value of its securities to decline. Poor performance may be caused by poor management decisions, competitive pressures, changes in technology, expiration of patent protection, disruptions in supply, labor problems or shortages, corporate restructurings, fraudulent disclosures or other factors. Issuers may, in times of distress or at their own discretion, decide to reduce or eliminate dividends, which may also cause their stock prices to decline.

Management Risk. The Fund may not fully replicate the Underlying Index and may hold securities not included in the Underlying Index. As a result, the Fund is subject to the risk that BFA’s investment management strategy, the implementation of which is subject to a number of constraints, may not produce the intended results.

Market Risk. The Fund could lose money due to short-term market movements and over longer periods during market downturns. Securities may decline in value due to factors affecting securities markets generally or particular industries represented in the markets. The value of a security may decline due to general market conditions, economic trends or events that are not specifically related to the issuer of the security or to factors that affect a particular industry or industries. During a general downturn in the securities markets, multiple asset classes may be negatively affected.

Market Trading Risk

Absence of Active Market. Although shares of the Fund are listed for trading on one or more stock exchanges, there can be no assurance that an active trading market for such shares will develop or be maintained.

Risk of Secondary Listings. The Fund’s shares may be listed or traded on U.S. and non-U.S. stock exchanges other than the U.S. stock exchange where the Fund’s primary listing is maintained. There can be no assurance that the Fund’s shares will continue to trade on any such stock exchange or in any market or that the Fund’s shares will continue to meet the requirements for listing or trading on any exchange or in any market. The Fund’s shares may be less actively traded in certain markets than others, and investors are subject to the execution and settlement risks and market standards of the market where they or their broker direct their trades for execution. Certain information available to investors who trade Fund shares on a U.S. stock exchange during regular U.S. market hours may not be available to investors who trade in other markets, which may result in secondary market prices in such markets being less efficient.

Secondary Market Trading Risk. Shares of the Fund may trade in the secondary market at times when the Fund does not accept orders to purchase or redeem shares. At such times, shares may trade in the secondary market with more significant premiums or discounts than might be experienced at times when the Fund accepts purchase and redemption orders.

Secondary market trading in Fund shares may be halted by a stock exchange because of market conditions or other reasons. In addition, trading in Fund shares on a stock exchange or in any market may be subject to trading halts caused by extraordinary market volatility pursuant to “circuit breaker” rules on the stock exchange or market. There can be no assurance that the requirements necessary to maintain the listing or trading of Fund shares will continue to be met or will remain unchanged.

Shares of the Fund May Trade at Prices Other Than NAV. Shares of the Fund trade on stock exchanges at prices at, above or below their most recent NAV. The NAV of the Fund is calculated at the end of each business day and fluctuates with changes in the market value of the Fund’s holdings since the most recent calculation. The trading prices of the Fund’s shares fluctuate continuously throughout trading hours based on market supply and demand rather than NAV. The trading prices of the Fund’s shares may deviate significantly from NAV during periods of market volatility. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV. However, because shares can be created and redeemed in Creation Units at NAV (unlike shares of many closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their NAVs), BFA believes that large discounts or premiums to the NAV of the Fund are not likely to be sustained over the long-term. While the creation/redemption feature is designed to make it likely that the Fund’s shares normally will trade on stock exchanges at prices close to the Fund’s next calculated NAV, exchange prices are not expected to correlate exactly with the Fund’s NAV due to timing reasons as well as market supply and demand factors. In addition, disruptions to creations and

redemptions or extreme market volatility may result in trading prices for shares of the Fund that differ significantly from its NAV.

Costs of Buying or Selling Fund Shares. Buying or selling Fund shares on an exchange involves two types of costs that apply to all securities transactions. When buying or selling shares of the Fund through a broker, you will likely incur a brokerage commission or other charges imposed by brokers as determined by that broker. In addition, you may incur the cost of the “spread” – that is, the difference between what investors are willing to pay for Fund shares (the “bid” price) and the price at which they are willing to sell Fund shares (the “ask” price). Because of the costs inherent in buying or selling Fund shares, frequent trading may detract significantly from investment results and an investment in Fund shares may not be advisable for investors who anticipate regularly making small investments.

Non-Diversification Risk. The Fund is classified as “non-diversified.” This means that the Fund may invest a large percentage of its assets in securities issued by or representing a small number of issuers. As a result, the Fund may be more susceptible to the risks associated with these particular issuers, or to a single economic, political or regulatory occurrence affecting these issuers.

Passive Investment Risk. The Fund is not actively managed and may be affected by a general decline in market segments related to the Underlying Index. The Fund invests in securities included in, or representative of, the Underlying Index regardless of their investment merits. BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

Securities Lending Risk. The Fund may engage in securities lending. Securities lending involves the risk that the Fund may lose money because the borrower of the Fund’s loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for the loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Technology Sector Risk. The Fund invests in technology companies, which face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Technology companies may have limited product lines, markets, financial resources or personnel. The products of technology companies may face obsolescence due to rapid technological developments and frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Companies in the technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies.

Tracking Error Risk. Imperfect correlation between the Fund’s portfolio securities and those in the Underlying Index, rounding of prices, changes to the Underlying Index and regulatory requirements may cause tracking error, which is the divergence of the Fund’s performance from that of the Underlying Index. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the

Underlying Index does not. Because the Fund employs a representative sampling strategy, the Fund may experience tracking error to a greater extent than a fund that seeks to replicate an index.

Portfolio Holdings Information

A description of the Trust’s policies and procedures with respect to the disclosure of the Fund’s portfolio securities is available in the Fund’s Statement of Additional Information (“SAI”). The top holdings of the Fund can be found at www.iShares.com. Fund fact sheets provide information regarding the Fund’s top holdings and may be requested by calling 1-800-iShares (1-800-474-2737).

Management

Investment Adviser. As investment adviser, BFA has overall responsibility for the general management and administration of the Trust. BFA provides an investment program for the Fund and manages the investment of the Fund’s assets. In managing the Fund, BFA may draw upon the research and expertise of its asset management affiliates with respect to certain portfolio securities. In seeking to achieve the Fund’s investment objective, BFA uses teams of portfolio managers, investment strategists and other investment specialists. This team approach brings together many disciplines and leverages BFA’s extensive resources.

Pursuant to the Investment Advisory Agreement between BFA and the Trust (entered into on behalf of the Fund), BFA is responsible for substantially all expenses of the Fund, except interest expenses, taxes, brokerage expenses, future distribution fees or expenses and extraordinary expenses.

For its investment advisory services to the Fund, BFA is entitled to receive a management fee from the Fund corresponding to the Fund’s allocable portion of an aggregate management fee based on the aggregate average daily net assets of the following iShares funds: iShares PHLX SOX Semiconductor Sector Index Fund, iShares S&P Global Clean Energy Index Fund, iShares S&P Global Consumer Discretionary Sector Index Fund, iShares S&P Global Consumer Staples Sector Index Fund, iShares S&P Global Energy Sector Index Fund, iShares S&P Global Financials Sector Index Fund, iShares S&P Global Healthcare Sector Index Fund, iShares S&P Global Industrials Sector Index Fund, iShares S&P Global Infrastructure Index Fund, iShares S&P Global Materials Sector Index Fund, iShares S&P Global Nuclear Energy Index Fund, iShares S&P Global Technology Sector Index Fund, iShares S&P Global Telecommunications Sector Index Fund, iShares S&P Global Timber & Forestry Index Fund, iShares S&P Global Utilities Sector Index Fund, iShares S&P North American Natural Resources Sector Index Fund, iShares S&P North American Technology Sector Index Fund, iShares S&P North American Technology-Multimedia Networking Index Fund and iShares S&P North American Technology-Software Index Fund. The aggregate management fee is calculated as follows: 0.48% per annum of the aggregate net assets less than or equal to $10.0 billion, plus 0.43% per annum of the aggregate net assets over $10.0 billion, up to and including $20.0 billion, plus 0.38% per annum of the aggregate net assets in excess of $20.0 billion. As calculated on July 31, 2011, for its investment advisory services to the Fund, BFA is entitled to receive a management fee

from the Fund, based on a percentage of the Fund’s average daily net assets, at an annual rate of 0.48%.

BFA is located at 400 Howard Street, San Francisco, CA 94105. It is a wholly owned subsidiary of BTC, which in turn is indirectly wholly-owned by BlackRock, Inc. (“BlackRock”). As of September 30, 2011, BTC and its affiliates, including BFA and BlackRock, provided investment advisory services for assets in excess of $3.35 trillion. BFA, BTC, BlackRock Execution Services, BlackRock and their affiliates deal, trade and invest for their own accounts in the types of securities in which the Fund may also invest.

A discussion regarding the basis for the Trust’s Board of Trustees’ (the “Board”) approval of the Investment Advisory Agreement with BFA is available in the Fund’s annual report for the period ended July 31.

Portfolio Managers. Rene Casis, Diane Hsiung and Greg Savage are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager is responsible for various functions related to portfolio management, including, but not limited to, investing cash inflows, coordinating with members of his or her portfolio management team to focus on certain asset classes, implementing investment strategy, researching and reviewing investment strategy and overseeing members of his or her portfolio management team that have more limited responsibilities.

Rene Casis has been employed by BFA (formerly, Barclays Global Fund Advisors (“BGFA”)) and BTC (formerly, Barclays Global Investors, N.A. (“BGI”)) as a senior portfolio manager since 2009. From 2005 to 2009, Mr. Casis was a trader at Barclays Capital. Prior to that, Mr. Casis was a portfolio manager from 2000 to 2005 for BGFA and BGI. Mr. Casis has been a Portfolio Manager of the Fund since 2010.

Diane Hsiung has been employed by BFA and BTC as a senior portfolio manager since 2007. Prior to that, Ms. Hsiung was a portfolio manager from 2002 to 2006 for BGFA and BGI. Ms. Hsiung has been a Portfolio Manager of the Fund since 2008.

Greg Savage has been employed by BFA and BTC as a senior portfolio manager since 2006. Prior to that, Mr. Savage was a portfolio manager from 2001 to 2006 for BGFA and BGI. Mr. Savage has been a Portfolio Manager of the Fund since 2008.

The Fund’s SAI provides additional information about the Portfolio Managers’ compensation, other accounts managed by the Portfolio Managers and the Portfolio Managers’ ownership (if any) of shares in the Fund.

Administrator, Custodian and Transfer Agent. State Street Bank and Trust Company (“State Street”) is the administrator, custodian and transfer agent for the Fund.

Conflicts of Interest. BFA wants you to know that there are certain entities with which BFA has relationships that may give rise to conflicts of interest, or the appearance of conflicts of interest. These entities include the following: BFA’s affiliates (including BlackRock and The PNC Financial Services Group, Inc., and each of their affiliates, directors, partners, trustees, managing members, officers and employees

(collectively, the “Affiliates”)) and BlackRock’s significant shareholder, Barclays Bank PLC and its affiliates, including Barclays PLC (each, an “Entity” and together, the “Entities”).

The activities of BFA, the Affiliates and the Entities in the management of, or their interest in, their own accounts and other accounts they manage, may present conflicts of interest that could disadvantage the Fund and its shareholders. BFA and its Affiliates or the Entities provide investment management services to other funds and discretionary managed accounts that may follow an investment program similar to that of the Fund. BFA, its Affiliates and the Entities are involved worldwide with a broad spectrum of financial services and asset management activities and may engage in the ordinary course of business in activities in which their interests or the interests of their clients may conflict with those of the Fund. BFA, one or more of the Affiliates or the Entities acts, or may act, as an investor, investment banker, research provider, investment manager, financier, underwriter, advisor, market maker, trader, prime broker, lender, agent or principal, and have other direct and indirect interests, in securities, currencies and other instruments in which the Fund may directly or indirectly invest. Thus, it is likely that the Fund will have multiple business relationships with and will invest in, engage in transactions with, make voting decisions with respect to, or obtain services from, entities for which BFA, an Affiliate or an Entity performs or seeks to perform investment banking or other services.

BFA or one or more Affiliates or Entities may engage in proprietary trading and advise accounts and funds that have investment objectives similar to those of the Fund and/or that engage in and compete for transactions in the same types of securities, currencies and other instruments as the Fund, including in securities issued by other open-end and closed-end investment management companies, including investment companies that are affiliated with the Fund and BFA, to the extent permitted under the Investment Company Act of 1940, as amended (the “1940 Act”). The trading activities of BFA, these Affiliates and Entities are carried out without reference to positions held directly or indirectly by the Fund and may result in BFA, an Affiliate or an Entity having positions that are adverse to those of the Fund.

No Affiliate or Entity is under any obligation to share any investment opportunity, idea or strategy with the Fund. As a result, an Affiliate or an Entity may compete with the Fund for appropriate investment opportunities. As a result of this and several other factors, the results of the Fund’s investment activities may differ from those of an Affiliate or an Entity and of other accounts managed by an Affiliate or an Entity, and it is possible that the Fund could sustain losses during periods in which one or more Affiliates or Entities and other accounts achieve profits on their trading for proprietary or other accounts. The opposite result is also possible.

The Fund may, from time to time, enter into transactions in which BFA or an Affiliate’s or an Entity’s clients have an interest adverse to the Fund. Furthermore, transactions undertaken by Affiliate-advised clients may adversely impact the Fund. Transactions by one or more Affiliate- or Entity-advised clients or BFA may have the effect of diluting or otherwise disadvantaging the values, prices or investment strategies of the Fund.

An Entity may maintain securities indices as part of its product offerings. Index-based funds seek to track the performance of securities indices and may use the name of the

index in the fund name. Index providers, including the Entities, may be paid licensing fees for use of their indices or index names. Entities will not be obligated to license their indices to BFA and its Affiliates, and BFA and its Affiliates will not be assured that the terms of any index licensing agreement with the Entities will be as favorable as those terms offered to other index licensees.

The Fund’s activities may be limited because of regulatory restrictions applicable to one or more Affiliates or Entities, and/or their internal policies designed to comply with such restrictions. In addition, the Fund may invest in securities of companies with which an Affiliate or an Entity has or is trying to develop investment banking relationships or in which an Affiliate or an Entity has significant debt or equity investments. The Fund also may invest in securities of companies for which an Affiliate or an Entity provides or may some day provide research coverage. An Affiliate or an Entity may have business relationships with and purchase or distribute or sell services or products from or to distributors, consultants or others who recommend the Fund or who engage in transactions with or for the Fund, and may receive compensation for such services. The Fund may also make brokerage and other payments to Affiliates or Entities in connection with the Fund’s portfolio investment transactions.

Pursuant to a securities lending program approved by the Board, the Fund has retained an Affiliate of BFA to serve as the securities lending agent for the Fund to the extent that the Fund participates in the securities lending program. For these services, the lending agent may receive a fee from the Fund, including a fee based on the returns earned on the Fund’s investment of the cash received as collateral for any loaned securities. In addition, one or more Affiliates may be among the entities to which the Fund may lend its portfolio securities under the securities lending program.

The activities of BFA, the Affiliates or Entities may give rise to other conflicts of interest that could disadvantage the Fund and its shareholders. BFA has adopted policies and procedures designed to address these potential conflicts of interest. See the Fund’s SAI for further information.

Buying and Selling Shares. Shares of the Fund may be acquired or redeemed directly from the Fund only in Creation Units or multiples thereof, as discussed in the Creations and Redemptions section of this Prospectus. Only an Authorized Participant (as defined in the Creations and Redemptions section) may engage in creation or redemption transactions directly with the Fund. Once created, shares of the Fund generally trade in the secondary market in amounts less than a Creation Unit.

Shares of the Fund are listed on a national securities exchange for trading during the trading day. Shares can be bought and sold throughout the trading day like shares of other publicly-traded companies. The Trust does not impose any minimum investment for shares of the Fund purchased on an exchange. The Fund’s shares trade under the trading symbol “IGV.”

Buying or selling Fund shares on an exchange involves two types of costs that may apply to all securities transactions. When buying or selling shares of the Fund through a broker, you will likely incur a brokerage commission or other charges determined by your broker. The commission is frequently a fixed amount and may be a significant proportional cost for investors seeking to buy or sell small amounts of shares. In addition, you may incur the cost of the “spread” – that is, any difference between the bid price and the ask price. The spread varies over time for shares of the Fund based on its trading volume and market liquidity, and is generally lower if the Fund has a lot of trading volume and market liquidity, and higher if the Fund has little trading volume and market liquidity.

The Board has adopted a policy of not monitoring for frequent purchases and redemptions of Fund shares (“frequent trading”) that appear to attempt to take advantage of a potential arbitrage opportunity presented by a lag between a change in the value of the Fund’s portfolio securities after the close of the primary markets for the Fund’s portfolio securities and the reflection of that change in the Fund’s NAV (“market timing”), because the Fund generally sells and redeems its shares directly through transactions that are in-kind and/or for cash, subject to the conditions described below under Creations and Redemptions. The Board has not adopted a policy of monitoring for other frequent trading activity because shares of the Fund are listed for trading on a national securities exchange.

The national securities exchange on which the Fund’s shares are listed is open for trading Monday through Friday and is closed on weekends and the following holidays: New Year’s Day, Martin Luther King, Jr. Day, Presidents’ Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day. The Fund’s primary listing exchange is NYSE Arca.

Section 12(d)(1) of the 1940 Act restricts investments by investment companies in the securities of other investment companies. Registered investment companies are permitted to invest in the Fund beyond the limits set forth in Section 12(d)(1), subject to certain terms and conditions set forth in SEC rules or in an SEC exemptive order issued to the Trust. In order for a registered investment company to invest in shares of the Fund beyond the limitations of Section 12(d)(1) pursuant to the exemptive relief obtained by the Trust, the registered investment company must enter into an agreement with the Trust.

Book Entry. Shares of the Fund are held in book-entry form, which means that no stock certificates are issued. The Depository Trust Company (“DTC”) or its nominee is the record owner of all outstanding shares of the Fund and is recognized as the owner of all shares for all purposes.

Investors owning shares of the Fund are beneficial owners as shown on the records of DTC or its participants. DTC serves as the securities depository for shares of the Fund. DTC participants include securities brokers and dealers, banks, trust companies, clearing corporations and other institutions that directly or indirectly maintain a custodial relationship with DTC. As a beneficial owner of shares, you are not entitled to receive physical delivery of stock certificates or to have shares registered in your name, and you are not considered a registered owner of shares. Therefore, to exercise any right as an owner of shares, you must rely upon the procedures of DTC and its

participants. These procedures are the same as those that apply to any other securities that you hold in book-entry or “street name” form.

Share Prices. The trading prices of the Fund’s shares in the secondary market generally differ from the Fund’s daily NAV and are affected by market forces such as supply and demand, economic conditions and other factors. Information regarding the intraday value of shares of the Fund, also known as the “indicative optimized portfolio value” (“IOPV”), is disseminated every 15 seconds throughout the trading day by the national securities exchange on which the Fund’s shares are listed or by market data vendors or other information providers. The IOPV is based on the current market value of the securities and/or cash required to be deposited in exchange for a Creation Unit. The IOPV does not necessarily reflect the precise composition of the current portfolio of securities held by the Fund at a particular point in time or the best possible valuation of the current portfolio. Therefore, the IOPV should not be viewed as a “real-time” update of the Fund’s NAV, which is computed only once a day. The IOPV is generally determined by using both current market quotations and/or price quotations obtained from broker-dealers that may trade in the portfolio securities held by the Fund. The quotations of certain Fund holdings may not be updated during U.S. trading hours if such holdings do not trade in the United States. The Fund is not involved in, or responsible for, the calculation or dissemination of the IOPV and makes no representation or warranty as to its accuracy.

Determination of Net Asset Value. The NAV of the Fund normally is determined once daily Monday through Friday, generally as of the regularly scheduled close of business of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m., Eastern time) on each day that the NYSE is open for trading, based on prices at the time of closing provided that (a) any Fund assets or liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers (as detailed below) and (b) U.S. fixed income assets may be valued as of the announced closing time for trading in fixed income instruments in a particular market or exchange. The NAV of the Fund is calculated by dividing the value of the net assets of the Fund (i.e., the value of its total assets less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets held by the Fund, and its liabilities, are determined pursuant to valuation policies and procedures approved by the Board. The Fund’s assets and liabilities are valued primarily on the basis of market quotations.

Equity investments are valued at market value, which is generally determined using the last reported official closing price or last trading price on the exchange or market on which the security is primarily traded at the time of valuation.

Generally, trading in foreign securities, U.S. government securities, money market instruments and certain fixed-income securities is substantially completed each day at various times prior to the close of business on the NYSE. The values of such securities used in computing the NAV of the Fund are determined as of such times.

When market quotations are not readily available or are believed by BFA to be unreliable, the Fund’s investments are valued at fair value. Fair value determinations

are made by BFA in accordance with policies and procedures approved by the Fund’s Board. BFA may conclude that a market quotation is not readily available or is unreliable if a security or other asset or liability does not have a price source due to its lack of liquidity, if a market quotation differs significantly from recent price quotations or otherwise no longer appears to reflect fair value, where the security or other asset or liability is thinly traded, or where there is a significant event subsequent to the most recent market quotation. A “significant event” is an event that, in the judgment of BFA, is likely to cause a material change to the closing market price of the asset or liability held by the Fund. Foreign securities whose values are affected by volatility that occurs in U.S. markets on a trading day after the close of foreign securities markets may be fair valued.

Fair value represents a good faith approximation of the value of an asset or liability. The fair value of an asset or liability held by the Fund is the amount the Fund might reasonably expect to receive from the current sale of that asset or the cost to extinguish that liability in an arm’s-length transaction. Valuing the Fund’s investments using fair value pricing will result in prices that may differ from current market valuations and that may not be the price at which those investments could have been sold during the period in which the particular fair values were used. Use of fair value prices and certain current market valuations could result in a difference between the prices used to calculate the Fund’s NAV and the prices used by the Underlying Index, which, in turn, could result in a difference between the Fund’s performance and the performance of the Underlying Index.

Dividends and Distributions

General Policies. Dividends from net investment income, if any, generally are declared and paid quarterly by the Fund. Distributions of net realized securities gains, if any, generally are declared and paid once a year, but the Trust may make distributions on a more frequent basis for the Fund. The Trust reserves the right to declare special distributions if, in its reasonable discretion, such action is necessary or advisable to preserve its status as a regulated investment company (“RIC”) or to avoid imposition of income or excise taxes on undistributed income or realized gains.

Dividends and other distributions on shares of the Fund are distributed on a pro rata basis to beneficial owners of such shares. Dividend payments are made through DTC participants and indirect participants to beneficial owners then of record with proceeds received from the Fund.

Dividend Reinvestment Service. No dividend reinvestment service is provided by the Trust. Broker-dealers may make available the DTC book-entry Dividend Reinvestment Service for use by beneficial owners of the Fund for reinvestment of their dividend distributions. Beneficial owners should contact their broker to determine the availability and costs of the service and the details of participation therein. Brokers may require beneficial owners to adhere to specific procedures and timetables. If this service is available and used, dividend distributions of both income and realized gains will be automatically reinvested in additional whole shares of the Fund purchased in the secondary market.

Taxes. As with any investment, you should consider how your investment in shares of the Fund will be taxed. The tax information in this Prospectus is provided as general information, based on current law. You should consult your own tax professional about the tax consequences of an investment in shares of the Fund.

Unless your investment in Fund shares is made through a tax-exempt entity or tax-deferred retirement account, such as an IRA, you need to be aware of the possible tax consequences when the Fund makes distributions or you sell Fund shares.

Taxes on Distributions. Distributions from the Fund’s net investment income (other than qualified dividend income), including distributions of income from securities lending and distributions out of the Fund’s net short-term capital gains, if any, are taxable to you as ordinary income. Distributions by the Fund of net long-term capital gains in excess of net short-term capital losses (capital gain dividends) are taxable to you as long-term capital gains, generally at a 15% tax rate (0% at certain income levels), regardless of how long you have held the Fund’s shares. Distributions by the Fund that qualify as qualified dividend income are taxable to you at long-term capital gain rates for taxable years beginning on or before December 31, 2012. The 15% and 0% tax rates expire for taxable years beginning after December 31, 2012. Maximum long-term capital gain income tax rates are scheduled to rise to 20% in 2013. Beginning in 2013, a 3.8% U.S. federal Medicare contribution tax will be imposed on “net investment income,” including interest, dividends, and capital gains, of U.S. individuals with income exceeding $200,000 (or $250,000 if married and filing jointly), and of estates and trusts.

Dividends will be qualified dividend income to you if they are attributable to qualified dividend income received by the Fund. Generally, qualified dividend income includes dividend income from taxable U.S. corporations and qualified non-U.S. corporations, provided that the Fund satisfies certain holding period requirements in respect of the stock of such corporations and has not hedged its position in the stock in certain ways. Substitute dividends received by the Fund with respect to dividends paid on securities lent out will not be qualified dividend income. For this purpose, a qualified non-U.S. corporation means any non-U.S. corporation that is eligible for benefits under a comprehensive income tax treaty with the United States, which includes an exchange of information program or if the stock with respect to which the dividend was paid is readily tradable on an established United States securities market. The term excludes a corporation that is a passive foreign investment company.

Dividends received by the Fund from a real estate investment trust (“REIT”) or another RIC generally are qualified dividend income only to the extent the dividend distributions are made out of qualified dividend income received by such REIT or RIC. It is expected that dividends received by the Fund from a REIT and distributed to a shareholder generally will be taxable to the shareholder as ordinary income.

For a dividend to be treated as qualified dividend income, the dividend must be received with respect to a share of stock held without being hedged by the Fund, and with respect to a share of the Fund held without being hedged by you, for 61 days during the 121-day period beginning at the date which is 60 days before the date on

which such share becomes ex-dividend with respect to such dividend or, in the case of certain preferred stock, 91 days during the 181-day period beginning 90 days before such date.

If your Fund shares are loaned out pursuant to a securities lending arrangement, you may lose the ability to use foreign tax credits passed through by the Fund or to treat Fund dividends paid while the shares are held by the borrower as qualified dividend income.

In general, your distributions are subject to U.S. federal income tax for the year when they are paid. Certain distributions paid in January, however, may be treated as paid on December 31 of the prior year.

If the Fund’s distributions exceed current and accumulated earnings and profits, all or a portion of the distributions made in the taxable year may be recharacterized as a return of capital to shareholders. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and result in a higher capital gain or lower capital loss when those shares on which the distribution was received are sold. Once a shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain, if the shareholder holds shares of the Fund as capital assets.

If you are neither a resident nor a citizen of the United States or if you are a non-U.S. entity, the Fund’s ordinary income dividends (which include distributions of net short-term capital gains) will generally be subject to a 30% U.S. withholding tax, unless a lower treaty rate applies, provided that withholding tax will generally not apply to any gain or income realized by a non-U.S. shareholder in respect of any distributions of long-term capital gains or upon the sale or other disposition of shares of the Fund.

A 30% withholding tax will be imposed on dividends paid after December 31, 2013, and redemption proceeds paid after December 31, 2014, to (i) foreign financial institutions including non-U.S. investment funds unless they agree to collect and disclose to the Internal Revenue Service (“IRS”) information regarding their direct and indirect U.S. account holders and (ii) certain other foreign entities, unless they certify certain information regarding their direct and indirect U.S. owners. To avoid withholding, foreign financial institutions will need to enter into agreements with the IRS that state that they will provide the IRS information, including the name, address and taxpayer identification number of direct and indirect U.S. account holders, comply with due diligence procedures with respect to the identification of U.S. accounts, report to the IRS certain information with respect to U.S. accounts maintained, agree to withhold tax on certain payments made to non-compliant foreign financial institutions or to account holders who fail to provide the required information, and determine certain other information as to their account holders. Other foreign entities will need to provide the name, address, and taxpayer identification number of each substantial U.S. owner or certifications of no substantial U.S. ownership unless certain exceptions apply.

Dividends, interest and capital gains received by the Fund with respect to non-U.S. securities may give rise to withholding and other taxes imposed by non-U.S. countries. Tax conventions between certain countries and the United States may reduce or eliminate such taxes.

If you are a resident or a citizen of the United States, by law, back-up withholding will apply to your distributions and proceeds if you have not provided a taxpayer identification number or social security number and made other required certifications.

Taxes When Shares are Sold. Currently, any capital gain or loss realized upon a sale of Fund shares is generally treated as a long-term gain or loss if the shares have been held for more than one year. Any capital gain or loss realized upon a sale of Fund shares held for one year or less is generally treated as short-term gain or loss, except that any capital loss on the sale of shares held for six months or less is treated as long-term capital loss to the extent that capital gain dividends were paid with respect to such shares. Beginning in 2013, any such capital gains, including from sales of Fund shares or from capital gain dividends, will be included in “net investment income” for purposes of the 3.8% U.S. federal Medicare contribution tax mentioned above.

The foregoing discussion summarizes some of the consequences under current U.S. federal tax law of an investment in the Fund. It is not a substitute for personal tax advice. You may also be subject to state and local taxation on Fund distributions and sales of shares. Consult your personal tax adviser about the potential tax consequences of an investment in shares of the Fund under all applicable tax laws.

Creations and Redemptions. Prior to trading in the secondary market, shares of the Fund are “created” at NAV by market makers, large investors and institutions only in block-size Creation Units of 50,000 shares or multiples thereof. Each “creator” or “Authorized Participant” enters into an authorized participant agreement with the Fund’s distributor, SEI Investments Distribution Co. (the “Distributor”). Only an Authorized Participant may create or redeem Creation Units directly with the Fund. A creation transaction, which is subject to acceptance by the transfer agent, generally takes place when an Authorized Participant deposits into the Fund a designated portfolio of securities and a specified amount of cash approximating the holdings of the Fund in exchange for a specified number of Creation Units. To the extent practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund.

Similarly, shares can be redeemed only in Creation Units, generally for a designated portfolio of securities and a specified amount of cash held by the Fund (“Fund Securities”). Except when aggregated in Creation Units, shares are not redeemable by the Fund. The prices at which creations and redemptions occur are based on the next calculation of NAV after an order is received in a form described in the authorized participant agreement.

The Fund intends to comply with the U.S. federal securities laws in accepting securities for deposit and satisfying redemptions with redemption securities by, among other means, assuring that any securities accepted for deposit and any securities used to satisfy redemption requests will be sold in transactions that would be exempt from registration under the Securities Act of 1933, as amended (the “1933 Act”). Further, an Authorized Participant that is not a “qualified institutional buyer,” as such term is defined under Rule 144A of the 1933 Act, will not be able to receive Fund Securities that are restricted securities eligible for resale under Rule 144A.

Creations and redemptions must be made through a firm that is either a member of the Continuous Net Settlement System of the National Securities Clearing Corporation or a DTC participant and has executed an agreement with the Distributor with respect to creations and redemptions of Creation Unit aggregations. Information about the procedures regarding creation and redemption of Creation Units (including the cut-off times for receipt of creation and redemption orders) is included in the Fund’s SAI.

Because new shares may be created and issued on an ongoing basis, at any point during the life of the Fund a “distribution,” as such term is used in the 1933 Act, may be occurring. Broker-dealers and other persons are cautioned that some activities on their part may, depending on the circumstances, result in their being deemed participants in a distribution in a manner that could render them statutory underwriters and subject to the prospectus delivery and liability provisions of the 1933 Act. Any determination of whether one is an underwriter must take into account all the relevant facts and circumstances of each particular case.

Broker-dealers should also note that dealers who are not “underwriters” but are participating in a distribution (as contrasted to ordinary secondary transactions), and thus dealing with shares that are part of an “unsold allotment” within the meaning of Section 4(3)(C) of the 1933 Act, would be unable to take advantage of the prospectus delivery exemption provided by Section 4(3) of the 1933 Act. For delivery of prospectuses to exchange members, the prospectus delivery mechanism of Rule 153 under the 1933 Act is available only with respect to transactions on a national securities exchange.

Costs Associated with Creations and Redemptions. Authorized Participants are charged standard creation and redemption transaction fees to offset transfer and other transaction costs associated with the issuance and redemption of Creation Units. The standard creation and redemption transaction fees are set forth in the table below. The standard creation transaction fee is charged to the Authorized Participant on the day such Authorized Participant creates a Creation Unit, and is the same regardless of the number of Creation Units purchased by the Authorized Participant on the applicable business day. Similarly, the standard redemption transaction fee is charged to the Authorized Participant on the day such Authorized Participant redeems a Creation Unit, and is the same regardless of the number of Creation Units redeemed by the Authorized Participant on the applicable business day. Creations and redemptions for cash (when cash creations and redemptions (in whole or in part) are available or specified) are also subject to an additional charge (up to the maximum amounts shown in the table below). This charge is intended to compensate for brokerage, tax, foreign exchange, execution, market impact and other costs and expenses related to cash transactions. Investors who use the services of a broker or other financial intermediary may pay fees for such services.

The following table shows, as of September 30, 2011, the approximate value of one Creation Unit, standard fees and maximum additional charges for creations and redemptions (as described above):

Householding. Householding is an option available to certain Fund investors. Householding is a method of delivery, based on the preference of the individual investor, in which a single copy of certain shareholder documents can be delivered to investors who share the same address, even if their accounts are registered under different names. Please contact your broker-dealer if you are interested in enrolling in householding and receiving a single copy of prospectuses and other shareholder documents, or if you are currently enrolled in householding and wish to change your householding status.

Distribution

The Distributor distributes Creation Units for the Fund on an agency basis. The Distributor does not maintain a secondary market in shares of the Fund. The Distributor has no role in determining the policies of the Fund or the securities that are purchased or sold by the Fund. The Distributor’s principal address is One Freedom Valley Drive, Oaks, PA 19456.

In addition, BFA or its Affiliates make payments to broker-dealers, banks or other financial intermediaries (together, “intermediaries”) related to marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems, or their making shares of the Fund and certain other iShares funds available to their customers. Such payments, which may be significant to the intermediary, are not made by the Fund. Rather, such payments are made by BFA or its Affiliates from their own resources, which come directly or indirectly in part from fees paid by the iShares funds complex. Payments of this type are sometimes referred to as revenue-sharing payments. A financial intermediary may make decisions about which investment options it recommends or makes available, or the level of services provided, to its customers based on the revenue-sharing payments it is eligible to receive. Therefore, such payments to an intermediary create conflicts of interest between the intermediary and its customers and may cause the intermediary to recommend the Fund or other iShares funds over another investment. More information regarding these payments is contained in the Fund’s SAI. Please contact your salesperson or other investment professional for more information regarding any such payments his or her firm may receive from BFA or its Affiliates.

Financial Highlights

The financial highlights table is intended to help investors understand the Fund’s financial performance for the past five years. Certain information reflects financial results for a single share of the Fund. The total returns in the table represent the rate that an investor would have earned (or lost) on an investment in the Fund, assuming reinvestment of all dividends and distributions. This information has been audited by PricewaterhouseCoopers LLP, whose report is included, along with the Fund’s financial statements, in the Fund’s Annual Report (available upon request).

Supplemental Information

I. Premium/Discount Information

The table that follows presents information about the differences between the daily market price on secondary markets for shares of the Fund and the Fund’s NAV. NAV is the price at which the Fund issues and redeems shares. It is calculated in accordance with the standard formula for valuing mutual fund shares. The price used to calculate market returns (“Market Price”) of the Fund generally is determined using the midpoint between the highest bid and the lowest offer on the primary securities exchange on which shares of the Fund are listed for trading, as of the time that the Fund’s NAV is calculated. The Fund’s Market Price may be at, above or below its NAV. The NAV of the Fund will fluctuate with changes in the value of its portfolio holdings. The Market Price of the Fund will fluctuate in accordance with changes in its NAV, as well as market supply and demand.

Premiums or discounts are the differences (expressed as a percentage) between the NAV and Market Price of the Fund on a given day, generally at the time the NAV is calculated. A premium is the amount that the Fund is trading above the reported NAV, expressed as a percentage of the NAV. A discount is the amount that the Fund is trading below the reported NAV, expressed as a percentage of the NAV.

The following information shows the frequency of distributions of premiums and discounts for the Fund for each full calendar quarter of 2010 through September 30, 2011.

Each line in the table shows the number of trading days in which the Fund traded within the premium/discount range indicated. The number of trading days in each premium/discount range is also shown as a percentage of the total number of trading days in the period covered by the table. All data presented here represents past performance, which cannot be used to predict future results.

Premium/Discount Range
Number of Days
Percentage of Total Days
Between 0.5% and -0.5% 441 100.00%
   441 100.00%

II. Total Return Information

The tables that follow present information about the total returns of the Fund and the Underlying Index as of the fiscal year ended July 31, 2011.

“Average Annual Total Returns” represent the average annual change in value of an investment over the periods indicated. “Cumulative Total Returns” represent the total change in value of an investment over the periods indicated.

The Fund’s NAV is the value of one share of the Fund as calculated in accordance with the standard formula for valuing mutual fund shares. The NAV return is based on the NAV of the Fund and the market return is based on the Market Price of the Fund. Market Price is determined by using the midpoint between the highest bid and the lowest offer on the primary stock exchange on which shares of the Fund are listed for trading, as of the time that the Fund’s NAV is calculated. Market and NAV returns assume that dividends and capital gain distributions have been reinvested in the Fund at Market Price and NAV, respectively.

An index is a statistical composite that tracks a specified financial market or sector. Unlike the Fund, the Underlying Index does not actually hold a portfolio of securities and therefore does not incur the expenses incurred by the Fund. These expenses negatively impact the performance of the Fund. Also, market returns do not include brokerage commissions that may be payable on secondary market transactions. If brokerage commissions were included, market returns would be lower. The returns shown in the following tables do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption or sale of Fund shares. The investment return and principal value of shares of the Fund will vary with changes in market conditions. Shares of the Fund may be worth more or less than their original cost when they are redeemed or sold in the market. The Fund’s past performance is no guarantee of future results.

iShares S&P Target Date Retirement Income Index Fund

iShares S&P Target Date Retirement
Income Index Fund

Ticker: TGR Stock Exchange: NYSE Arca

Investment Objective

The iShares S&P Target Date Retirement Income Index Fund (the “Fund”) seeks investment results that correspond generally to the price and yield performance, before fees and expenses, of the S&P Target Date Retirement Income Index (the “Underlying Index”).

Fees and Expenses

The following table describes the fees and expenses that you will incur if you own shares of the Fund. The investment advisory agreement between iShares Trust (the “Trust”) and BlackRock Fund Advisors (“BFA”) (the “Investment Advisory Agreement”) provides that BFA will pay all operating expenses of the Fund, except interest expenses, taxes, brokerage expenses, future distribution fees or expenses, and extraordinary expenses. “Acquired Fund Fees and Expenses” reflect the Fund’s pro rata share of the fees and expenses incurred by investing in other investment companies. The impact of Acquired Fund Fees and Expenses is included in the total returns of the Fund. Acquired Fund Fees and Expenses are not used to calculate the Fund’s net asset value per share (“NAV”) and are not included in the calculation of the ratio of expenses to average net assets shown in the Financial Highlights section of the Fund’s prospectus (the “Prospectus”). BFA has contractually agreed to waive a portion of the advisory fee it is entitled to receive from the Fund due to its investments in other iShares funds, in an amount equal to 0.14%, through June 30, 2013. The contractual waiver may be terminated prior to June 30, 2013 only upon written agreement of the Trust and BFA.

You will also incur usual and customary brokerage commissions when buying or selling shares of the Fund, which are not reflected in the example that follows:

percentage of the value of your investments)

Example. This Example is intended to help you compare the cost of owning shares of the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

1 Year
3 Years
5 Years
10 Years
$31 $118 $224 $533

Portfolio Turnover. The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 20% of the average value of its portfolio.

Principal Investment Strategies

The Fund is a fund of funds and seeks its investment objective by investing primarily in the securities of other iShares funds (each, an “Underlying Fund” and collectively, the “Underlying Funds”) that themselves seek investment results corresponding to their own underlying index. The Underlying Funds invest primarily in distinct asset classes, such as large-capitalization U.S. equity, mid-capitalization U.S. equity, emerging market securities, the aggregate bond market or the U.S. Treasury bond market; each such asset class has its own risk profile.

It is the goal of the Underlying Index to represent an allocation strategy geared towards investors who are currently retired or are close to retirement.

The Underlying Index seeks to represent asset allocations which reflect an immediate retirement horizon, i.e., asset allocations geared toward investors who are currently retired or are close to retirement, but only you can determine whether or not the Fund’s asset allocation reflects your risk tolerance and investment needs. The Fund may not be appropriate for all investors who are currently retired or are close to retirement. The Underlying Index’s asset allocation is not static and may change over time. While the Underlying Index has an asset allocation that is intended to be appropriate for a person who is currently retired, the Fund is still exposed to risk of loss and could suffer significant losses. There is no guarantee that the Fund will provide adequate income through your retirement.

The Fund is designed to broadly meet the investment objectives of investors nearing or currently in retirement by tracking the Underlying Index. As of September 30, 2011, the Fund invested approximately 29.43% of its assets in Underlying Funds that

S-1   


Table Of Contents



invest primarily in equity securities, 70.44% of its assets in Underlying Funds that invest primarily in fixed-income securities and the remainder of its assets in Underlying Funds that invest primarily in money market instruments.

As of September 30, 2011, the Fund invested in the iShares S&P 500 Index Fund, iShares S&P MidCap 400 Index Fund, iShares S&P SmallCap 600 Index Fund, iShares MSCI EAFE Index Fund, iShares Barclays Aggregate Bond Fund, iShares Barclays Short Treasury Bond Fund, iShares Barclays TIPS Bond Fund, iShares iBoxx $ High Yield Corporate Bond Fund and BlackRock Cash Funds. BFA may add, eliminate or replace any and/or all Underlying Funds at any time.

BFA uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to “beat” the index it tracks and does not seek temporary defensive positions when markets decline or appear overvalued.

Indexing may eliminate the chance that the Fund will substantially outperform the Underlying Index but also may reduce some of the risks of active management, such as poor security selection. Indexing seeks to achieve lower costs and better after-tax performance by keeping portfolio turnover low in comparison to actively managed investment companies.

BFA uses a representative sampling indexing strategy to manage the Funds. “Representative sampling” is an indexing strategy that involves investing in a representative sample of securities that collectively has an investment profile similar to the Underlying Index. The securities selected are expected to have, in the aggregate, investment characteristics (based on factors such as market capitalization and industry weightings), fundamental characteristics (such as return variability and yield) and liquidity measures similar to those of the Underlying Index. The Fund may or may not hold all of the securities in the Underlying Index.

The Fund generally invests at least 90% of its assets in securities of the Underlying Index. The Fund may invest the remainder of its assets in securities not included in the Underlying Index, but which BFA believes will help the Fund track its Underlying Index and in other investments including futures contracts, options on futures contracts and options, as well as cash and cash equivalents, including shares of money market funds affiliated with BFA or its affiliates, to the extent permitted under the Investment Company Act of 1940, as amended (the “1940 Act”).

The Fund may lend securities representing up to one-third of the value of the Fund’s total assets (including the value of the collateral received).

The Underlying Index is sponsored by an organization (the “Index Provider”) that is independent of the Fund and BFA. The Index Provider determines the composition and relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index. The Fund’s Index Provider is Standard & Poor’s Financial Services LLC (a subsidiary of The McGraw-Hill Companies) (“S&P”).

Industry Concentration Policy. The Fund will concentrate its investments (i.e., hold 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. For purposes of this limitation, securities of the U.S. government (including its agencies and instrumentalities) and repurchase agreements collateralized by U.S. government securities are not considered to be issued by members of any industry.

Summary of Principal Risks

As with any investment, you could lose all or part of your investment in the Fund, and the Fund’s performance could trail that of other investments. The Fund is subject to the principal risks noted below (either directly or through its investments in the Underlying Funds), any of which may adversely affect the Fund’s NAV, trading price, yield, total return and ability to meet its investment objective.

Asset Class Risk. Securities in the Underlying Index or in the Fund’s portfolio may underperform in comparison to the general securities markets or other asset classes.

Credit Risk. The risk that debt issuers and other counterparties may not honor their obligations or may have their debt downgraded by ratings agencies.

Equity Securities Risk. Equity securities are subject to changes in value and their values may be more volatile than other asset classes.

Financial Sector Risk. Performance of companies in the financial sector may be adversely impacted by many factors, including, among others, government regulations, economic conditions, credit rating downgrades, changes in interest rates, and decreased liquidity in credit markets. This sector has experienced significant losses in the recent past, and the impact of more stringent capital requirements and of recent or future regulation on any individual financial company or on the sector as a whole cannot be predicted.

Industrials Sector Risk. The industrials sector is affected by changes in the supply and demand for products and services, product obsolescence, claims for environmental damage or product liability and general economic conditions, among other factors.

Interest Rate Risk. An increase in interest rates may cause the value of fixed-income securities held by the Fund or an Underlying Fund to decline.

Issuer Risk. Fund performance depends on the performance of individual securities to which the Fund or an Underlying Fund has exposure. Changes to the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA’s investment management strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares, losses from trading in secondary markets, periods of high volatility and disruption in the creation/redemption process of the Fund. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV.

Model Risk. Neither the Fund nor BFA can offer assurances that the Underlying Index’s allocation model will maximize returns or

S-2   


Table Of Contents



minimize risk, or be appropriate for every investor seeking a particular risk profile.

Mortgage-Backed Securities Risk. The Fund invests in mortgage-backed securities (“MBS”), some of which may not be backed by the full faith and credit of the U.S. government. MBS are subject to prepayment risk and extension risk. Because of these risks, MBS react differently to changes in interest rates than other bonds. Small movements in interest rates (both increases and decreases) may quickly and significantly reduce the value of certain MBS.

Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers are subject to the risks associated with investing in those non-U.S. markets, such as heightened risks of inflation or nationalization. The Fund may lose money due to political, economic and geographic events affecting a non-U.S. issuer or market.

Passive Investment Risk. The Fund is not actively managed and BFA does not attempt to take defensive positions under any market conditions, including declining markets.

Reinvestment Risk. The Fund or an Underlying Fund invests in short-term fixed-income instruments and may be adversely affected if interest rates fall because it may invest in lower yielding bonds as bonds in the portfolio mature.

Securities Lending Risk. The Fund or an Underlying Fund may engage in securities lending. Securities lending involves the risk that the Fund or an Underlying Fund may lose money because the borrower of the Fund’s loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Tracking Error Risk. The performance of the Fund may diverge from that of the Underlying Index. Because the Fund employs a representative sampling strategy, the Fund may experience tracking error to a greater extent than a fund that seeks to replicate an index.

Treasury Obligations Risk. Treasury obligations may differ in their interest rates, maturities, times of issuance and other characteristics. Similar to other issuers, changes to the financial condition or credit rating of a government may cause the value of the Fund’s Treasury obligations to decline.

Valuation Risk. The value of the securities in the Fund’s portfolio may change on days when shareholders will not be able to purchase or sell the Fund’s shares.

Performance Information

The bar chart and table that follow show how the Fund has performed on a calendar year basis and provide an indication of the risks of investing in the Fund. Both assume that all dividends and distributions have been reinvested in the Fund. Past performance (before and after taxes) does not necessarily indicate how the Fund will perform in the future. Supplemental information about the Fund’s performance is shown under the heading Total Return Information in the Supplemental Information section of the Prospectus.

1 After-tax returns in the table above are calculated using the historical highest individual U.S. federal marginal income tax rates and do not reflect the impact of state or local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown, and after-tax returns shown are not relevant to tax-exempt investors or investors who hold shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts (“IRAs”). Fund returns after taxes on distributions and sale of Fund shares are calculated assuming that an investor has sufficient capital gains of the same character from other investments to offset any capital losses from the sale of Fund shares. As a result, Fund returns after taxes on distributions and sale of Fund shares may exceed Fund returns before taxes and/or returns after taxes on distributions.

Management

Investment Adviser. BlackRock Fund Advisors.

Portfolio Managers. Rene Casis, Diane Hsiung and Greg Savage (the “Portfolio Managers”) are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager supervises a portfolio management team. Mr. Casis has been a Portfolio Manager of the Fund since 2010. Ms. Hsiung and Mr. Savage have been Portfolio Managers of the Fund since inception.

Purchase and Sale of Fund Shares

The Fund is an exchange-traded fund (commonly referred to as an “ETF”). Individual Fund shares may only be purchased and sold on a national securities exchange through a broker-dealer. The price of Fund shares is based on market price, and because ETF shares trade at market prices rather than NAV, shares may trade at a price greater than NAV (a premium) or less than NAV (a discount). The Fund will only issue or redeem shares that have been aggregated into blocks of 50,000 shares or multiples thereof (“Creation Units”) to authorized participants who have entered into agreements with the Fund’s distributor. The Fund generally will issue or redeem Creation Units in return for a designated portfolio of securities (and an amount of cash) that the Fund specifies each day.

Tax Information

The Fund intends to make distributions that may be taxable to you as ordinary income or capital gains, unless you are investing through a tax-deferred arrangement such as a 401(k) plan or an IRA.

Payments to Broker-Dealers and other Financial Intermediaries

If you purchase shares of the Fund through a broker-dealer or other financial intermediary (such as a bank), BFA or other related companies may pay the intermediary for marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems or other services related to the sale or promotion of the Funds. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Funds over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.

A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 28% of the average value of its portfolio.

Principal Investment Strategies

The Fund is a fund of funds and seeks its investment objective by investing primarily in the securities of other iShares funds (each, an “Underlying Fund” and collectively, the “Underlying Funds”) that themselves seek investment results corresponding to their own underlying index. The Underlying Funds invest primarily in distinct asset classes, such as large-capitalization U.S. equity, mid-capitalization U.S. equity, emerging market securities, the aggregate bond market or the U.S. Treasury bond market; each such asset class has its own risk profile.

The retirement time horizon, also referred to as a “target date,” is included in the name of an underlying index and a fund that invests in the securities of such underlying index. A fund whose index name refers to a particular target date is designed for investors expecting to retire or to begin to gradually withdraw their money around such target date.

The Underlying Index seeks to represent asset allocations for investors with a target retirement horizon on or around 2010, but only you can determine whether or not the Fund’s asset allocation reflects your risk tolerance and investment needs. The Fund may not be appropriate for all investors with this target retirement horizon. The Underlying Index’s asset allocation may continue to grow more conservative after the target date. The Fund will continue to be exposed to risk of loss after the target date. There is no guarantee that the Fund will provide adequate income through your retirement.

The Fund is designed to broadly meet the investment objectives of investors with an approximate 2010 target retirement horizon by tracking the Underlying Index. As of September 30, 2011, the Fund invested approximately 41.87% of its assets in Underlying Funds that invest primarily in equity securities, 57.95% of its assets in Underlying Funds that invest primarily in fixed-income

securities and the remainder of its assets in Underlying Funds that invest primarily in money market instruments.

As of September 30, 2011, the Fund invested in the iShares S&P 500 Index Fund, iShares S&P MidCap 400 Index Fund, iShares S&P SmallCap 600 Index Fund, iShares MSCI EAFE Index Fund, iShares MSCI Emerging Markets Index Fund, iShares Barclays Aggregate Bond Fund, iShares Barclays Short Treasury Bond Fund, iShares Barclays TIPS Bond Fund, iShares iBoxx $ High Yield Corporate Bond Fund and BlackRock Cash Funds. BFA may add, eliminate or replace any and/or all Underlying Funds at any time.

BFA uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to “beat” the index it tracks and does not seek temporary defensive positions when markets decline or appear overvalued.

Indexing may eliminate the chance that the Fund will substantially outperform the Underlying Index but also may reduce some of the risks of active management, such as poor security selection. Indexing seeks to achieve lower costs and better after-tax performance by keeping portfolio turnover low in comparison to actively managed investment companies.

BFA uses a representative sampling indexing strategy to manage the Funds. “Representative sampling” is an indexing strategy that involves investing in a representative sample of securities that collectively has an investment profile similar to the Underlying Index. The securities selected are expected to have, in the aggregate, investment characteristics (based on factors such as market capitalization and industry weightings), fundamental characteristics (such as return variability and yield) and liquidity measures similar to those of the Underlying Index. The Fund may or may not hold all of the securities in the Underlying Index.

The Fund generally invests at least 90% of its assets in securities of the Underlying Index. The Fund may invest the remainder of its assets in securities not included in the Underlying Index, but which BFA believes will help the Fund track its Underlying Index and in other investments including futures contracts, options on futures contracts and options, as well as cash and cash equivalents, including shares of money market funds affiliated with BFA or its affiliates, to the extent permitted under the Investment Company Act of 1940, as amended (the “1940 Act”).

The Fund may lend securities representing up to one-third of the value of the Fund’s total assets (including the value of the collateral received).

The Underlying Index is sponsored by an organization (the “Index Provider”) that is independent of the Fund and BFA. The Index Provider determines the composition and relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index. The Fund’s Index Provider is Standard & Poor’s Financial Services LLC (a subsidiary of The McGraw-Hill Companies) (“S&P”).

Industry Concentration Policy. The Fund will concentrate its investments (i.e., hold 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. For purposes of this limitation, securities ofthe U.S. government (including its agencies and instrumentalities) and repurchase agreements collateralized by U.S. government securities are not considered to be issued by members of any industry.

Summary of Principal Risks

As with any investment, you could lose all or part of your investment in the Fund, and the Fund’s performance could trail that of other investments. The Fund is subject to the principal risks noted below (either directly or through its investments in the Underlying Funds), any of which may adversely affect the Fund’s NAV, trading price, yield, total return and ability to meet its investment objective.

Asset Class Risk. Securities in the Underlying Index or in the Fund’s portfolio may underperform in comparison to the general securities markets or other asset classes.

Credit Risk. The risk that debt issuers and other counterparties may not honor their obligations or may have their debt downgraded by ratings agencies.

Equity Securities Risk. Equity securities are subject to changes in value and their values may be more volatile than other asset classes.

Financial Sector Risk. Performance of companies in the financial sector may be adversely impacted by many factors, including, among others, government regulations, economic conditions, credit rating downgrades, changes in interest rates, and decreased liquidity in credit markets. This sector has experienced significant losses in the recent past, and the impact of more stringent capital requirements and of recent or future regulation on any individual financial company or on the sector as a whole cannot be predicted.

Interest Rate Risk. An increase in interest rates may cause the value of fixed-income securities held by the Fund or an Underlying Fund to decline.

Issuer Risk. Fund performance depends on the performance of individual securities to which the Fund or an Underlying Fund has exposure. Changes to the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA’s investment management strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares, losses from trading in secondary markets, periods of high volatility and disruption in the creation/redemption process of the Fund. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV.

Model Risk. Neither the Fund nor BFA can offer assurances that the Underlying Index’s allocation model will maximize returns or minimize risk, or be appropriate for every investor seeking a particular risk profile.

Mortgage-Backed Securities Risk. The Fund invests in mortgage-backed securities (“MBS”), some of which may not be backed by the full faith and credit of the U.S. government. MBS are subject to prepayment risk and extension risk. Because of these risks, MBS react differently to changes in interest rates than other bonds. Small movements in

S-6   


Table Of Contents



interest rates (both increases and decreases) may quickly and significantly reduce the value of certain MBS.

Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers are subject to the risks associated with investing in those non-U.S. markets, such as heightened risks of inflation or nationalization. The Fund may lose money due to political, economic and geographic events affecting a non-U.S. issuer or market.

Passive Investment Risk. The Fund is not actively managed and BFA does not attempt to take defensive positions under any market conditions, including declining markets.

Reinvestment Risk. The Fund or an Underlying Fund invests in short-term fixed-income instruments and may be adversely affected if interest rates fall because it may invest in lower yielding bonds as bonds in the portfolio mature.

Risk of Investing in Russia. Investing in Russian securities involves significant risks, including legal, regulatory and economic risks that are specific to Russia. In addition, investing in Russian securities involves risks associated with the settlement of portfolio transactions and loss of the Fund’s ownership rights in its portfolio securities, as a result of the system of share registration and custody in Russia.

Securities Lending Risk. The Fund or an Underlying Fund may engage in securities lending. Securities lending involves the risk that the Fund or an Underlying Fund may lose money because the borrower of the Fund’s loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Tracking Error Risk. The performance of the Fund may diverge from that of the Underlying Index. Because the Fund employs a representative sampling strategy, the Fund may experience tracking error to a greater extent than a fund that seeks to replicate an index.

Treasury Obligations Risk. Treasury obligations may differ in their interest rates, maturities, times of issuance and other characteristics. Similar to other issuers, changes to the financial condition or credit rating of a government may cause the value of the Fund’s Treasury obligations to decline.

Valuation Risk. The value of the securities in the Fund’s portfolio may change on days when shareholders will not be able to purchase or sell the Fund’s shares.

Performance Information

The bar chart and table that follow show how the Fund has performed on a calendar year basis and provide an indication of the risks of investing in the Fund.

1 After-tax returns in the table above are calculated using the historical highest individual U.S. federal marginal income tax rates and do not reflect the impact of state or local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown, and after-tax returns shown are not relevant to tax-exempt investors or investors who hold shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts (“IRAs”). Fund returns after taxes on distributions and sale of Fund shares are calculated assuming that an investor has sufficient capital gains of the same character from other investments to offset any capital losses from the sale of Fund shares. As a result, Fund returns after taxes on distributions and sale of Fund shares may exceed Fund returns before taxes and/or returns after taxes on distributions.

Management

Investment Adviser. BlackRock Fund Advisors.

Portfolio Managers. Rene Casis, Diane Hsiung and Greg Savage (the “Portfolio Managers”) are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager supervises a portfolio management team. Mr. Casis has been a Portfolio Manager of the Fund since 2010. Ms. Hsiung and Mr. Savage have been Portfolio Managers of the Fund since inception.

Purchase and Sale of Fund Shares

The Fund is an exchange-traded fund (commonly referred to as an “ETF”). Individual Fund shares may only be purchased and sold on a national securities exchange through a broker-dealer. The price of Fund shares is based on market price, and because ETF shares trade at market prices rather than NAV, shares may trade at a price greater than NAV (a premium) or less than NAV (a discount). The Fund will only issue or redeem shares that have been aggregated into blocks of 50,000 shares or multiples thereof (“Creation Units”) to authorized participants who have entered into agreements with the Fund’s distributor. The Fund generally will issue or redeem Creation Units in return for a designated portfolio of securities (and an amount of cash) that the Fund specifies each day.

Tax Information

The Fund intends to make distributions that may be taxable to you as ordinary income or capital gains, unless you are investing through a tax-deferred arrangement such as a 401(k) plan or an IRA.

Payments to Broker-Dealers and other Financial Intermediaries

If you purchase shares of the Fund through a broker-dealer or other financial intermediary (such as a bank), BFA or other related companies may pay the intermediary for marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems or other services related to the sale or promotion of the Funds. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Funds over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.

iShares S&P Target Date 2015 Index Fund

iShares S&P Target Date 2015 Index Fund

Ticker: TZE Stock Exchange: NYSE Arca

Investment Objective

The iShares S&P Target Date 2015 Index Fund (the “Fund”) seeks investment results that correspond generally to the price and yield performance, before fees and expenses, of the S&P Target Date 2015 Index (the “Underlying Index”).

Fees and Expenses

The following table describes the fees and expenses that you will incur if you own shares of the Fund. The investment advisory agreement between iShares Trust (the “Trust”) and BlackRock Fund Advisors (“BFA”) (the “Investment Advisory Agreement”) provides that BFA will pay all operating expenses of the Fund, except interest expenses, taxes, brokerage expenses, future distribution fees or expenses, and extraordinary expenses. “Acquired Fund Fees and Expenses” reflect the Fund’s pro rata share of the fees and expenses incurred by investing in other investment companies. The impact of Acquired Fund Fees and Expenses is included in the total returns of the Fund. Acquired Fund Fees and Expenses are not used to calculate the Fund’s net asset value per share (“NAV”) and are not included in the calculation of the ratio of expenses to average net assets shown in the Financial Highlights section of the Fund’s prospectus (the “Prospectus”). BFA has contractually agreed to waive a portion of the advisory fee it is entitled to receive from the Fund due to its investments in other iShares funds, in an amount equal to 0.14%, through June 30, 2013. The contractual waiver may be terminated prior to June 30, 2013 only upon written agreement of the Trust and BFA.

You will also incur usual and customary brokerage commissions when buying or selling shares of the Fund, which are not reflected in the example that follows:

Example. This Example is intended to help you compare the cost of owning shares of the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

1 Year
3 Years
5 Years
10 Years
$31 $118 $224 $533

Portfolio Turnover. The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 24% of the average value of its portfolio.

Principal Investment Strategies

The Fund is a fund of funds and seeks its investment objective by investing primarily in the securities of other iShares funds (each, an “Underlying Fund” and collectively, the “Underlying Funds”) that themselves seek investment results corresponding to their own underlying index. The Underlying Funds invest primarily in distinct asset classes, such as large-capitalization U.S. equity, mid-capitalization U.S. equity, emerging market securities, the aggregate bond market or the U.S. Treasury bond market; each such asset class has its own risk profile.

The retirement time horizon, also referred to as a “target date,” is included in the name of an underlying index and a fund that invests in the securities of such underlying index. A fund whose index name refers to a particular target date is designed for investors expecting to retire or to begin to gradually withdraw their money around such target date.

The Underlying Index seeks to represent asset allocations for investors with a target retirement horizon on or around 2015, but only you can determine whether or not the Fund’s asset allocation reflects your risk tolerance and investment needs. The Fund may not be appropriate for all investors with this target retirement horizon. The Underlying Index’s asset allocation may continue to grow more conservative after the target date. The Fund will continue to be exposed to risk of loss after the target date. There is no guarantee that the Fund will provide adequate income through your retirement.

The Fund is designed to broadly meet the investment objectives of investors with an approximate 2015 target retirement horizon by tracking the Underlying Index. As of September 30, 2011, the Fund invested approximately 53.04% of its assets in Underlying Funds that invest primarily in equity securities, 46.73% of its assets in Underlying Funds that invest primarily in fixed-income

S-9

securities and the remainder of its assets in Underlying Funds that invest primarily in money market instruments.

As of September 30, 2011, the Fund invested in the iShares S&P 500 Index Fund, iShares S&P MidCap 400 Index Fund, iShares S&P SmallCap 600 Index Fund, iShares Cohen & Steers Realty Majors Index Fund, iShares MSCI EAFE Index Fund, iShares MSCI Emerging Markets Index Fund, iShares Barclays Aggregate Bond Fund, iShares Barclays Short Treasury Bond Fund, iShares Barclays TIPS Bond Fund, iShares iBoxx $ High Yield Corporate Bond Fund and BlackRock Cash Funds. BFA may add, eliminate or replace any and/or all Underlying Funds at any time.

BFA uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to “beat” the index it tracks and does not seek temporary defensive positions when markets decline or appear overvalued.

Indexing may eliminate the chance that the Fund will substantially outperform the Underlying Index but also may reduce some of the risks of active management, such as poor security selection.

The securities selected are expected to have, in the aggregate, investment characteristics (based on factors such as market capitalization and industry weightings), fundamental characteristics (such as return variability and yield) and liquidity measures similar to those of the Underlying Index.

The Fund may lend securities representing up to one-third of the value of the Fund’s total assets (including the value of the collateral received).

The Underlying Index is sponsored by an organization (the “Index Provider”) that is independent of the Fund and BFA. The Index Provider determines the composition and relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index. The Fund’s Index Provider is Standard & Poor’s Financial Services LLC (a subsidiary of The McGraw-Hill Companies) (“S&P”).

Industry Concentration Policy. The Fund will concentrate its investments (i.e., hold 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. For purposes of this limitation, securities ofthe U.S. government (including its agencies and instrumentalities) and repurchase agreements collateralized by U.S. government securities are not considered to be issued by members of any industry.

This sector has experienced significant losses in the recent past, and the impact of more stringent capital requirements and of recent or future regulation on any individual financial company or on the sector as a whole cannot be predicted.

Information Technology Sector Risk. Information technology companies face intense competition and potentially rapid product obsolescence. They are also heavily dependent on intellectual property rights and may be adversely affected by loss or impairment of those rights.

Interest Rate Risk. An increase in interest rates may cause the value of fixed-income securities held by the Fund or an Underlying Fund to decline.

A fund whose index name refers to a particular target date is designed for investors expecting to retire or to begin to gradually withdraw their money around such target date.

The Underlying Index seeks to represent asset allocations for investors with a target retirement horizon on or around 2020, but only you can determine whether or not the Fund’s asset allocation reflects your risk tolerance and investment needs. The Fund may not be appropriate for all investors with this target retirement horizon. The Underlying Index’s asset allocation may continue to grow more conservative after the target date. The Fund will continue to be exposed to risk of loss after the target date. There is no guarantee that the Fund will provide adequate income through your retirement.

The Fund is designed to broadly meet the investment objectives of investors with an approximate 2020 target retirement horizon by tracking the Underlying Index. As of September 30, 2011, the Fund invested approximately 62.51% of its assets in Underlying Funds that invest primarily in equity securities, 37.22% of its assets in Underlying Funds that invest primarily in fixed-income

S-13   


Table Of Contents



securities and the remainder of its assets in Underlying Funds that invest primarily in money market instruments.

As of September 30, 2011, the Fund invested in the iShares S&P 500 Index Fund, iShares S&P MidCap 400 Index Fund, iShares S&P SmallCap 600 Index Fund, iShares Cohen & Steers Realty Majors Index Fund, iShares MSCI EAFE Index Fund, iShares MSCI Emerging Markets Index Fund, iShares Barclays Aggregate Bond Fund, iShares Barclays Short Treasury Bond Fund, iShares Barclays TIPS Bond Fund, iShares iBoxx $ High Yield Corporate Bond Fund and BlackRock Cash Funds. BFA may add, eliminate or replace any and/or all Underlying Funds at any time.

BFA uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to “beat” the index it tracks and does not seek temporary defensive positions when markets decline or appear overvalued.

Indexing may eliminate the chance that the Fund will substantially outperform the Underlying Index but also may reduce some of the risks of active management, such as poor security selection. Indexing seeks to achieve lower costs and better after-tax performance by keeping portfolio turnover low in comparison to actively managed investment companies.

BFA uses a representative sampling indexing strategy to manage the Funds. “Representative sampling” is an indexing strategy that involves investing in a representative sample of securities that collectively has an investment profile similar to the Underlying Index. The securities selected are expected to have, in the aggregate, investment characteristics (based on factors such as market capitalization and industry weightings), fundamental characteristics (such as return variability and yield) and liquidity measures similar to those of the Underlying Index. The Fund may or may not hold all of the securities in the Underlying Index.

The Fund generally invests at least 90% of its assets in securities of the Underlying Index. The Fund may invest the remainder of its assets in securities not included in the Underlying Index, but which BFA believes will help the Fund track its Underlying Index and in other investments including futures contracts, options on futures contracts and options, as well as cash and cash equivalents, including shares of money market funds affiliated with BFA or its affiliates, to the extent permitted under the Investment Company Act of 1940, as amended (the “1940 Act”).

The Fund may lend securities representing up to one-third of the value of the Fund’s total assets (including the value of the collateral received).

The Underlying Index is sponsored by an organization (the “Index Provider”) that is independent of the Fund and BFA. The Index Provider determines the composition and relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index. The Fund’s Index Provider is Standard & Poor’s Financial Services LLC (a subsidiary of The McGraw-Hill Companies) (“S&P”).

Industry Concentration Policy. The Fund will concentrate its investments (i.e., hold 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. For purposes of this limitation, securities ofthe U.S. government (including its agencies and instrumentalities) and repurchase agreements collateralized by U.S. government securities are not considered to be issued by members of any industry.

Summary of Principal Risks

As with any investment, you could lose all or part of your investment in the Fund, and the Fund’s performance could trail that of other investments. The Fund is subject to the principal risks noted below (either directly or through its investments in the Underlying Funds), any of which may adversely affect the Fund’s NAV, trading price, yield, total return and ability to meet its investment objective.

Asset Class Risk. Securities in the Underlying Index or in the Fund’s portfolio may underperform in comparison to the general securities markets or other asset classes.

Credit Risk. The risk that debt issuers and other counterparties may not honor their obligations or may have their debt downgraded by ratings agencies.

Equity Securities Risk. Equity securities are subject to changes in value and their values may be more volatile than other asset classes.

Financial Sector Risk. Performance of companies in the financial sector may be adversely impacted by many factors, including, among others, government regulations, economic conditions, credit rating downgrades, changes in interest rates, and decreased liquidity in credit markets. This sector has experienced significant losses in the recent past, and the impact of more stringent capital requirements and of recent or future regulation on any individual financial company or on the sector as a whole cannot be predicted.

Information Technology Sector Risk. Information technology companies face intense competition and potentially rapid product obsolescence. They are also heavily dependent on intellectual property rights and may be adversely affected by loss or impairment of those rights.

Interest Rate Risk. An increase in interest rates may cause the value of fixed-income securities held by the Fund or an Underlying Fund to decline.

Issuer Risk. Fund performance depends on the performance of individual securities to which the Fund or an Underlying Fund has exposure. Changes to the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA’s investment management strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares, losses from trading in secondary markets, periods of high volatility and disruption in the creation/redemption process of the Fund. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV.

Model Risk. Neither the Fund nor BFA can offer assurances that the Underlying Index’s allocation model will maximize returns or

S-14   


Table Of Contents



minimize risk, or be appropriate for every investor seeking a particular risk profile.

Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers are subject to the risks associated with investing in those non-U.S. markets, such as heightened risks of inflation or nationalization. The Fund may lose money due to political, economic and geographic events affecting a non-U.S. issuer or market.

Passive Investment Risk. The Fund is not actively managed and BFA does not attempt to take defensive positions under any market conditions, including declining markets.

Reinvestment Risk. The Fund or an Underlying Fund invests in short-term fixed-income instruments and may be adversely affected if interest rates fall because it may invest in lower yielding bonds as bonds in the portfolio mature.

Risk of Investing in Russia. Investing in Russian securities involves significant risks, including legal, regulatory and economic risks that are specific to Russia. In addition, investing in Russian securities involves risks associated with the settlement of portfolio transactions and loss of the Fund’s ownership rights in its portfolio securities, as a result of the system of share registration and custody in Russia.

Securities Lending Risk. The Fund or an Underlying Fund may engage in securities lending. Securities lending involves the risk that the Fund or an Underlying Fund may lose money because the borrower of the Fund’s loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Tracking Error Risk. The performance of the Fund may diverge from that of the Underlying Index. Because the Fund employs a representative sampling strategy, the Fund may experience tracking error to a greater extent than a fund that seeks to replicate an index.

Treasury Obligations Risk. Treasury obligations may differ in their interest rates, maturities, times of issuance and other characteristics. Similar to other issuers, changes to the financial condition or credit rating of a government may cause the value of the Fund’s Treasury obligations to decline.

Valuation Risk. The value of the securities in the Fund’s portfolio may change on days when shareholders will not be able to purchase or sell the Fund’s shares.

Performance Information

The bar chart and table that follow show how the Fund has performed on a calendar year basis and provide an indication of the risks of investing in the Fund.

1 After-tax returns in the table above are calculated using the historical highest individual U.S. federal marginal income tax rates and do not reflect the impact of state or local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown, and after-tax returns shown are not relevant to tax-exempt investors or investors who hold shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts (“IRAs”). Fund returns after taxes on distributions and sale of Fund shares are calculated assuming that an investor has sufficient capital gains of the same character from other investments to offset any capital losses from the sale of Fund shares. As a result, Fund returns after taxes on distributions and sale of Fund shares may exceed Fund returns before taxes and/or returns after taxes on distributions.

Management

Investment Adviser. BlackRock Fund Advisors.

Portfolio Managers. Rene Casis, Diane Hsiung and Greg Savage (the “Portfolio Managers”) are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager supervises a portfolio management team. Mr. Casis has been a Portfolio Manager of the Fund since 2010. Ms. Hsiung and Mr. Savage have been Portfolio Managers of the Fund since inception.

Purchase and Sale of Fund Shares

The Fund is an exchange-traded fund (commonly referred to as an “ETF”). Individual Fund shares may only be purchased and sold on a national securities exchange through a broker-dealer. The price of Fund shares is based on market price, and because ETF shares trade at market prices rather than NAV, shares may trade at a price greater than NAV (a premium) or less than NAV (a discount). The Fund will only issue or redeem shares that have been aggregated into blocks of 50,000 shares or multiples thereof (“Creation Units”) to authorized participants who have entered into agreements with the Fund’s distributor. The Fund generally will issue or redeem Creation Units in return for a designated portfolio of securities (and an amount of cash) that the Fund specifies each day.

Tax Information

The Fund intends to make distributions that may be taxable to you as ordinary income or capital gains, unless you are investing through a tax-deferred arrangement such as a 401(k) plan or an IRA.

Payments to Broker-Dealers and other Financial Intermediaries

If you purchase shares of the Fund through a broker-dealer or other financial intermediary (such as a bank), BFA or other related companies may pay the intermediary for marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems or other services related to the sale or promotion of the Funds. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Funds over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.

iShares S&P Target Date 2025 Index Fund

iShares S&P Target Date 2025 Index Fund

Ticker: TZI Stock Exchange: NYSE Arca

Investment Objective

The iShares S&P Target Date 2025 Index Fund (the “Fund”) seeks investment results that correspond generally to the price and yield performance, before fees and expenses, of the S&P Target Date 2025 Index (the “Underlying Index”).

Fees and Expenses

The following table describes the fees and expenses that you will incur if you own shares of the Fund. The investment advisory agreement between iShares Trust (the “Trust”) and BlackRock Fund Advisors (“BFA”) (the “Investment Advisory Agreement”) provides that BFA will pay all operating expenses of the Fund, except interest expenses, taxes, brokerage expenses, future distribution fees or expenses, and extraordinary expenses. “Acquired Fund Fees and Expenses” reflect the Fund’s pro rata share of the fees and expenses incurred by investing in other investment companies. The impact of Acquired Fund Fees and Expenses is included in the total returns of the Fund. Acquired Fund Fees and Expenses are not used to calculate the Fund’s net asset value per share (“NAV”) and are not included in the calculation of the ratio of expenses to average net assets shown in the Financial Highlights section of the Fund’s prospectus (the “Prospectus”). BFA has contractually agreed to waive a portion of the advisory fee it is entitled to receive from the Fund due to its investments in other iShares funds, in an amount equal to 0.14%, through June 30, 2013. The contractual waiver may be terminated prior to June 30, 2013 only upon written agreement of the Trust and BFA.

You will also incur usual and customary brokerage commissions when buying or selling shares of the Fund, which are not reflected in the example that follows:

Example. This Example is intended to help you compare the cost of owning shares of the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

1 Year
3 Years
5 Years
10 Years
$31 $118 $224 $533

Portfolio Turnover. The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 17% of the average value of its portfolio.

Principal Investment Strategies

The Fund is a fund of funds and seeks its investment objective by investing primarily in the securities of other iShares funds (each, an “Underlying Fund” and collectively, the “Underlying Funds”) that themselves seek investment results corresponding to their own underlying index. The Underlying Funds invest primarily in distinct asset classes, such as large-capitalization U.S. equity, mid-capitalization U.S. equity, emerging market securities, the aggregate bond market or the U.S. Treasury bond market; each such asset class has its own risk profile.

The retirement time horizon, also referred to as a “target date,” is included in the name of an underlying index and a fund that invests in the securities of such underlying index. A fund whose index name refers to a particular target date is designed for investors expecting to retire or to begin to gradually withdraw their money around such target date.

The Underlying Index seeks to represent asset allocations for investors with a target retirement horizon on or around 2025, but only you can determine whether or not the Fund’s asset allocation reflects your risk tolerance and investment needs. The Fund may not be appropriate for all investors with this target retirement horizon. The Underlying Index’s asset allocation may continue to grow more conservative after the target date. The Fund will continue to be exposed to risk of loss after the target date. There is no guarantee that the Fund will provide adequate income through your retirement.

The Fund is designed to broadly meet the investment objectives of investors with an approximate 2025 target retirement horizon by tracking the Underlying Index. As of September 30, 2011, the Fund invested approximately 70.73% of its assets in Underlying Funds that invest primarily in equity securities, 28.98% of its assets in Underlying Funds that invest primarily in fixed-income

S-17

securities and the remainder of its assets in Underlying Funds that invest primarily in money market instruments.

As of September 30, 2011, the Fund invested in the iShares S&P 500 Index Fund, iShares S&P MidCap 400 Index Fund, iShares S&P SmallCap 600 Index Fund, iShares Cohen & Steers Realty Majors Index Fund, iShares MSCI EAFE Index Fund, iShares MSCI Emerging Markets Index Fund, iShares Barclays Aggregate Bond Fund, iShares Barclays Short Treasury Bond Fund, iShares Barclays TIPS Bond Fund, iShares iBoxx $ High Yield Corporate Bond Fund and BlackRock Cash Funds. BFA may add, eliminate or replace any and/or all Underlying Funds at any time.

BFA uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to “beat” the index it tracks and does not seek temporary defensive positions when markets decline or appear overvalued.

The Fund is a fund of funds and seeks its investment objective by investing primarily in the securities of other iShares funds (each, an “Underlying Fund” and collectively, the “Underlying Funds”) that themselves seek investment results corresponding to their own underlying index. The Underlying Funds invest primarily in distinct asset classes, such as large-capitalization U.S. equity, mid-capitalization U.S. equity, emerging market securities, the aggregate bond market or the U.S. Treasury bond market; each such asset class has its own risk profile.

The retirement time horizon, also referred to as a “target date,” is included in the name of an underlying index and a fund that invests in the securities of such underlying index. A fund whose index name refers to a particular target date is designed for investors expecting to retire or to begin to gradually withdraw their money around such target date.

The Underlying Index seeks to represent asset allocations for investors with a target retirement horizon on or around 2030, but only you can determine whether or not the Fund’s asset allocation reflects your risk tolerance and investment needs. The Fund may not be appropriate for all investors with this target retirement horizon. The Underlying Index’s asset allocation may continue to grow more conservative after the target date. The Fund will continue to be exposed to risk of loss after the target date. There is no guarantee that the Fund will provide adequate income through your retirement.

The Fund is designed to broadly meet the investment objectives of investors with an approximate 2030 target retirement horizon by tracking the Underlying Index. As of September 30, 2011, the Fund invested approximately 78.38% of its assets in Underlying Funds that invest primarily in equity securities, 21.30% of its assets in Underlying Funds that invest primarily in fixed-income

S-21   


Table Of Contents



securities and the remainder of its assets in Underlying Funds that invest primarily in money market instruments.

As of September 30, 2011, the Fund invested in the iShares S&P 500 Index Fund, iShares S&P MidCap 400 Index Fund, iShares S&P SmallCap 600 Index Fund, iShares Cohen & Steers Realty Majors Index Fund, iShares MSCI EAFE Index Fund, iShares MSCI Emerging Markets Index Fund, iShares Barclays Aggregate Bond Fund, iShares Barclays Short Treasury Bond Fund, iShares iBoxx $ High Yield Corporate Bond Fund and BlackRock Cash Funds. BFA may add, eliminate or replace any and/or all Underlying Funds at any time.

BFA uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to “beat” the index it tracks and does not seek temporary defensive positions when markets decline or appear overvalued.

Indexing may eliminate the chance that the Fund will substantially outperform the Underlying Index but also may reduce some of the risks of active management, such as poor security selection. Indexing seeks to achieve lower costs and better after-tax performance by keeping portfolio turnover low in comparison to actively managed investment companies.

BFA uses a representative sampling indexing strategy to manage the Funds. “Representative sampling” is an indexing strategy that involves investing in a representative sample of securities that collectively has an investment profile similar to the Underlying Index. The securities selected are expected to have, in the aggregate, investment characteristics (based on factors such as market capitalization and industry weightings), fundamental characteristics (such as return variability and yield) and liquidity measures similar to those of the Underlying Index. The Fund may or may not hold all of the securities in the Underlying Index.

The Fund generally invests at least 90% of its assets in securities of the Underlying Index. The Fund may invest the remainder of its assets in securities not included in the Underlying Index, but which BFA believes will help the Fund track its Underlying Index and in other investments including futures contracts, options on futures contracts and options, as well as cash and cash equivalents, including shares of money market funds affiliated with BFA or its affiliates, to the extent permitted under the Investment Company Act of 1940, as amended (the “1940 Act”).

The Fund may lend securities representing up to one-third of the value of the Fund’s total assets (including the value of the collateral received).

The Underlying Index is sponsored by an organization (the “Index Provider”) that is independent of the Fund and BFA. The Index Provider determines the composition and relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index. The Fund’s Index Provider is Standard & Poor’s Financial Services LLC (a subsidiary of The McGraw-Hill Companies) (“S&P”).

Industry Concentration Policy. The Fund will concentrate its investments (i.e., hold 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. For purposes of this limitation, securities ofthe U.S. government (including its agencies and instrumentalities) and repurchase agreements collateralized by U.S. government securities are not considered to be issued by members of any industry.

Summary of Principal Risks

As with any investment, you could lose all or part of your investment in the Fund, and the Fund’s performance could trail that of other investments. The Fund is subject to the principal risks noted below (either directly or through its investments in the Underlying Funds), any of which may adversely affect the Fund’s NAV, trading price, yield, total return and ability to meet its investment objective.

Asset Class Risk. Securities in the Underlying Index or in the Fund’s portfolio may underperform in comparison to the general securities markets or other asset classes.

Consumer Discretionary Sector Risk. The consumer discretionary sector may be affected by changes in domestic and international economies, exchange and interest rates, competition, consumers’ disposable income and consumer preferences, social trends and marketing campaigns.

Credit Risk. The risk that debt issuers and other counterparties may not honor their obligations or may have their debt downgraded by ratings agencies.

Equity Securities Risk. Equity securities are subject to changes in value and their values may be more volatile than other asset classes.

Financial Sector Risk. Performance of companies in the financial sector may be adversely impacted by many factors, including, among others, government regulations, economic conditions, credit rating downgrades, changes in interest rates, and decreased liquidity in credit markets. This sector has experienced significant losses in the recent past, and the impact of more stringent capital requirements and of recent or future regulation on any individual financial company or on the sector as a whole cannot be predicted.

Health Care Sector Risk. The health care sector may be affected by government regulations and government health care programs, increases or decreases in the cost of medical products and services and product liability claims, among other factors. Many health care companies are heavily dependent on patent protection and the expiration of a patent may adversely affect their profitability. Health care companies are subject to competitive forces that may result in price discounting, and may be thinly capitalized and susceptible to product obsolescence.

Industrials Sector Risk. The industrials sector is affected by changes in the supply and demand for products and services, product obsolescence, claims for environmental damage or product liability and general economic conditions, among other factors.

Information Technology Sector Risk. Information technology companies face intense competition and potentially rapid product obsolescence. They are also heavily dependent on intellectual property rights and may be adversely affected by loss or impairment of those rights.

Interest Rate Risk. An increase in interest rates may cause the value of fixed-income securities held by the Fund or an Underlying Fund to decline.

Issuer Risk. Fund performance depends on the performance of individual securities to which the Fund or an Underlying Fund has

S-22   


Table Of Contents



exposure. Changes to the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA’s investment management strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares, losses from trading in secondary markets, periods of high volatility and disruption in the creation/redemption process of the Fund. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV.

Model Risk. Neither the Fund nor BFA can offer assurances that the Underlying Index’s allocation model will maximize returns or minimize risk, or be appropriate for every investor seeking a particular risk profile.

Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers are subject to the risks associated with investing in those non-U.S. markets, such as heightened risks of inflation or nationalization. The Fund may lose money due to political, economic and geographic events affecting a non-U.S. issuer or market.

Passive Investment Risk. The Fund is not actively managed and BFA does not attempt to take defensive positions under any market conditions, including declining markets.

Reinvestment Risk. The Fund or an Underlying Fund invests in short-term fixed-income instruments and may be adversely affected if interest rates fall because it may invest in lower yielding bonds as bonds in the portfolio mature.

Risk of Investing in Russia. Investing in Russian securities involves significant risks, including legal, regulatory and economic risks that are specific to Russia. In addition, investing in Russian securities involves risks associated with the settlement of portfolio transactions and loss of the Fund’s ownership rights in its portfolio securities, as a result of the system of share registration and custody in Russia.

Securities Lending Risk. The Fund or an Underlying Fund may engage in securities lending. Securities lending involves the risk that the Fund or an Underlying Fund may lose money because the borrower of the Fund’s loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Tracking Error Risk. The performance of the Fund may diverge from that of the Underlying Index. Because the Fund employs a representative sampling strategy, the Fund may experience tracking error to a greater extent than a fund that seeks to replicate an index.

Valuation Risk. The value of the securities in the Fund’s portfolio may change on days when shareholders will not be able to purchase or sell the Fund’s shares.

Actual after-tax returns depend on an investor’s tax situation and may differ from those shown, and after-tax returns shown are not relevant to tax-exempt investors or investors who hold shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts (“IRAs”). Fund returns after taxes on distributions and sale of Fund shares are calculated assuming that an investor has sufficient capital gains of the same character from other investments to offset any capital losses from the sale of Fund shares. As a result, Fund returns after taxes on distributions and sale of Fund shares may exceed Fund returns before taxes and/or returns after taxes on distributions.

Management

Investment Adviser. BlackRock Fund Advisors.

Portfolio Managers. Rene Casis, Diane Hsiung and Greg Savage (the “Portfolio Managers”) are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager supervises a portfolio management team. Mr. Casis has been a Portfolio Manager of the Fund since 2010. Ms. Hsiung and Mr. Savage have been Portfolio Managers of the Fund since inception.

Purchase and Sale of Fund Shares

The Fund is an exchange-traded fund (commonly referred to as an “ETF”). Individual Fund shares may only be purchased and sold on a national securities exchange through a broker-dealer. The price of Fund shares is based on market price, and because ETF shares trade at market prices rather than NAV, shares may trade at a price greater than NAV (a premium) or less than NAV (a discount). The Fund will only issue or redeem shares that have been aggregated into blocks of 50,000 shares or multiples thereof (“Creation Units”) to authorized participants who have entered into agreements with the Fund’s distributor. The Fund generally will issue or redeem Creation Units in return for a designated portfolio of securities (and an amount of cash) that the Fund specifies each day.

Tax Information

The Fund intends to make distributions that may be taxable to you as ordinary income or capital gains, unless you are investing through a tax-deferred arrangement such as a 401(k) plan or an IRA.

Payments to Broker-Dealers and other Financial Intermediaries

If you purchase shares of the Fund through a broker-dealer or other financial intermediary (such as a bank), BFA or other related companies may pay the intermediary for marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems or other services related to the sale or promotion of the Funds. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Funds over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.

iShares S&P Target Date 2035 Index Fund

iShares S&P Target Date 2035 Index Fund

Ticker: TZO Stock Exchange: NYSE Arca

Investment Objective

The iShares S&P Target Date 2035 Index Fund (the “Fund”) seeks investment results that correspond generally to the price and yield performance, before fees and expenses, of the S&P Target Date 2035 Index (the “Underlying Index”).

Fees and Expenses

The following table describes the fees and expenses that you will incur if you own shares of the Fund. The investment advisory agreement between iShares Trust (the “Trust”) and BlackRock Fund Advisors (“BFA”) (the “Investment Advisory Agreement”) provides that BFA will pay all operating expenses of the Fund, except interest expenses, taxes, brokerage expenses, future distribution fees or expenses, and extraordinary expenses. “Acquired Fund Fees and Expenses” reflect the Fund’s pro rata share of the fees and expenses incurred by investing in other investment companies. The impact of Acquired Fund Fees and Expenses is included in the total returns of the Fund. Acquired Fund Fees and Expenses are not used to calculate the Fund’s net asset value per share (“NAV”) and are not included in the calculation of the ratio of expenses to average net assets shown in the Financial Highlights section of the Fund’s prospectus (the “Prospectus”). BFA has contractually agreed to waive a portion of the advisory fee it is entitled to receive from the Fund due to its investments in other iShares funds, in an amount equal to 0.14%, through June 30, 2013. The contractual waiver may be terminated prior to June 30, 2013 only upon written agreement of the Trust and BFA.

You will also incur usual and customary brokerage commissions when buying or selling shares of the Fund, which are not reflected in the example that follows:

Example. This Example is intended to help you compare the cost of owning shares of the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

1 Year
3 Years
5 Years
10 Years
$32 $122 $229 $545

Portfolio Turnover. The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 30% of the average value of its portfolio.

Principal Investment Strategies

The Fund is a fund of funds and seeks its investment objective by investing primarily in the securities of other iShares funds (each, an “Underlying Fund” and collectively, the “Underlying Funds”) that themselves seek investment results corresponding to their own underlying index.

Example. This Example is intended to help you compare the cost of owning shares of the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

1 Year
3 Years
5 Years
10 Years
$32 $122 $229 $545

Portfolio Turnover. The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 15% of the average value of its portfolio.

Principal Investment Strategies

The Fund is a fund of funds and seeks its investment objective by investing primarily in the securities of other iShares funds (each, an “Underlying Fund” and collectively, the “Underlying Funds”) that themselves seek investment results corresponding to their own underlying index. The Underlying Funds invest primarily in distinct asset classes, such as large-capitalization U.S. equity, mid-capitalization U.S. equity, emerging market securities, the aggregate bond market or the U.S. Treasury bond market; each such asset class has its own risk profile.

The retirement time horizon, also referred to as a “target date,” is included in the name of an underlying index and a fund that invests in the securities of such underlying index. A fund whose index name refers to a particular target date is designed for investors expecting to retire or to begin to gradually withdraw their money around such target date.

The Underlying Index seeks to represent asset allocations for investors with a target retirement horizon on or around 2040, but only you can determine whether or not the Fund’s asset allocation reflects your risk tolerance and investment needs. The Fund may not be appropriate for all investors with this target retirement horizon. The Underlying Index’s asset allocation may continue to grow more conservative after the target date. The Fund will continue to be exposed to risk of loss after the target date. There is no guarantee that the Fund will provide adequate income through your retirement.

The Fund is designed to broadly meet the investment objectives of investors with an approximate 2040 target retirement horizon by tracking the Underlying Index. As of September 30, 2011, the Fund invested approximately 87.38% of its assets in Underlying Funds that invest primarily in equity securities, 12.28% of its assets in Underlying Funds that invest primarily in fixed-income

S-29   


Table Of Contents



securities and the remainder of its assets in Underlying Funds that invest primarily in money market instruments.

As of September 30, 2011, the Fund invested in the iShares S&P 500 Index Fund, iShares S&P MidCap 400 Index Fund, iShares S&P SmallCap 600 Index Fund, iShares Cohen & Steers Realty Majors Index Fund, iShares MSCI EAFE Index Fund, iShares MSCI Emerging Markets Index Fund, iShares Barclays Aggregate Bond Fund, iShares Barclays Short Treasury Bond Fund, iShares iBoxx $ High Yield Corporate Bond Fund and BlackRock Cash Funds. BFA may add, eliminate or replace any and/or all Underlying Funds at any time.

BFA uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to “beat” the index it tracks and does not seek temporary defensive positions when markets decline or appear overvalued.

Indexing may eliminate the chance that the Fund will substantially outperform the Underlying Index but also may reduce some of the risks of active management, such as poor security selection. Indexing seeks to achieve lower costs and better after-tax performance by keeping portfolio turnover low in comparison to actively managed investment companies.

BFA uses a representative sampling indexing strategy to manage the Funds. “Representative sampling” is an indexing strategy that involves investing in a representative sample of securities that collectively has an investment profile similar to the Underlying Index. The securities selected are expected to have, in the aggregate, investment characteristics (based on factors such as market capitalization and industry weightings), fundamental characteristics (such as return variability and yield) and liquidity measures similar to those of the Underlying Index. The Fund may or may not hold all of the securities in the Underlying Index.

The Fund generally invests at least 90% of its assets in securities of the Underlying Index. The Fund may invest the remainder of its assets in securities not included in the Underlying Index, but which BFA believes will help the Fund track its Underlying Index and in other investments including futures contracts, options on futures contracts and options, as well as cash and cash equivalents, including shares of money market funds affiliated with BFA or its affiliates, to the extent permitted under the Investment Company Act of 1940, as amended (the “1940 Act”).

The Fund may lend securities representing up to one-third of the value of the Fund’s total assets (including the value of the collateral received).

The Underlying Index is sponsored by an organization (the “Index Provider”) that is independent of the Fund and BFA. The Index Provider determines the composition and relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index. The Fund’s Index Provider is Standard & Poor’s Financial Services LLC (a subsidiary of The McGraw-Hill Companies) (“S&P”).

Industry Concentration Policy. The Fund will concentrate its investments (i.e., hold 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. For purposes of this limitation, securities ofthe U.S. government (including its agencies and instrumentalities) and repurchase agreements collateralized by U.S. government securities are not considered to be issued by members of any industry.

Summary of Principal Risks

As with any investment, you could lose all or part of your investment in the Fund, and the Fund’s performance could trail that of other investments. The Fund is subject to the principal risks noted below (either directly or through its investments in the Underlying Funds), any of which may adversely affect the Fund’s NAV, trading price, yield, total return and ability to meet its investment objective.

Asset Class Risk. Securities in the Underlying Index or in the Fund’s portfolio may underperform in comparison to the general securities markets or other asset classes.

Consumer Discretionary Sector Risk. The consumer discretionary sector may be affected by changes in domestic and international economies, exchange and interest rates, competition, consumers’ disposable income and consumer preferences, social trends and marketing campaigns.

Credit Risk. The risk that debt issuers and other counterparties may not honor their obligations or may have their debt downgraded by ratings agencies.

Equity Securities Risk. Equity securities are subject to changes in value and their values may be more volatile than other asset classes.

Financial Sector Risk. Performance of companies in the financial sector may be adversely impacted by many factors, including, among others, government regulations, economic conditions, credit rating downgrades, changes in interest rates, and decreased liquidity in credit markets. This sector has experienced significant losses in the recent past, and the impact of more stringent capital requirements and of recent or future regulation on any individual financial company or on the sector as a whole cannot be predicted.

Health Care Sector Risk. The health care sector may be affected by government regulations and government health care programs, increases or decreases in the cost of medical products and services and product liability claims, among other factors. Many health care companies are heavily dependent on patent protection and the expiration of a patent may adversely affect their profitability. Health care companies are subject to competitive forces that may result in price discounting, and may be thinly capitalized and susceptible to product obsolescence.

Industrials Sector Risk. The industrials sector is affected by changes in the supply and demand for products and services, product obsolescence, claims for environmental damage or product liability and general economic conditions, among other factors.

Information Technology Sector Risk. Information technology companies face intense competition and potentially rapid product obsolescence. They are also heavily dependent on intellectual property rights and may be adversely affected by loss or impairment of those rights.

Interest Rate Risk. An increase in interest rates may cause the value of fixed-income securities held by the Fund or an Underlying Fund to decline.

Issuer Risk. Fund performance depends on the performance of individual securities to which the Fund or an Underlying Fund has

S-30   


Table Of Contents



exposure. Changes to the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA’s investment management strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares, losses from trading in secondary markets, periods of high volatility and disruption in the creation/redemption process of the Fund. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV.

Model Risk. Neither the Fund nor BFA can offer assurances that the Underlying Index’s allocation model will maximize returns or minimize risk, or be appropriate for every investor seeking a particular risk profile.

Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers are subject to the risks associated with investing in those non-U.S. markets, such as heightened risks of inflation or nationalization. The Fund may lose money due to political, economic and geographic events affecting a non-U.S. issuer or market.

Passive Investment Risk. The Fund is not actively managed and BFA does not attempt to take defensive positions under any market conditions, including declining markets.

Reinvestment Risk. The Fund or an Underlying Fund invests in short-term fixed-income instruments and may be adversely affected if interest rates fall because it may invest in lower yielding bonds as bonds in the portfolio mature.

Risk of Investing in Russia. Investing in Russian securities involves significant risks, including legal, regulatory and economic risks that are specific to Russia. In addition, investing in Russian securities involves risks associated with the settlement of portfolio transactions and loss of the Fund’s ownership rights in its portfolio securities, as a result of the system of share registration and custody in Russia.

Securities Lending Risk. The Fund or an Underlying Fund may engage in securities lending. Securities lending involves the risk that the Fund or an Underlying Fund may lose money because the borrower of the Fund’s loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Tracking Error Risk. The performance of the Fund may diverge from that of the Underlying Index. Because the Fund employs a representative sampling strategy, the Fund may experience tracking error to a greater extent than a fund that seeks to replicate an index.

Valuation Risk. The value of the securities in the Fund’s portfolio may change on days when shareholders will not be able to purchase or sell the Fund’s shares.

Performance Information

The bar chart and table that follow show how the Fund has performed on a calendar year basis and provide an indication of the risks of investing in the Fund.

Actual after-tax returns depend on an investor’s tax situation and may differ from those shown, and after-tax returns shown are not relevant to tax-exempt investors or investors who hold shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts (“IRAs”). Fund returns after taxes on distributions and sale of Fund shares are calculated assuming that an investor has sufficient capital gains of the same character from other investments to offset any capital losses from the sale of Fund shares. As a result, Fund returns after taxes on distributions and sale of Fund shares may exceed Fund returns before taxes and/or returns after taxes on distributions.

Management

Investment Adviser. BlackRock Fund Advisors.

Portfolio Managers. Rene Casis, Diane Hsiung and Greg Savage (the “Portfolio Managers”) are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager supervises a portfolio management team. Mr. Casis has been a Portfolio Manager of the Fund since 2010. Ms. Hsiung and Mr. Savage have been Portfolio Managers of the Fund since inception.

Purchase and Sale of Fund Shares

The Fund is an exchange-traded fund (commonly referred to as an “ETF”). Individual Fund shares may only be purchased and sold on a national securities exchange through a broker-dealer. The price of Fund shares is based on market price, and because ETF shares trade at market prices rather than NAV, shares may trade at a price greater than NAV (a premium) or less than NAV (a discount). The Fund will only issue or redeem shares that have been aggregated into blocks of 50,000 shares or multiples thereof (“Creation Units”) to authorized participants who have entered into agreements with the Fund’s distributor. The Fund generally will issue or redeem Creation Units in return for a designated portfolio of securities (and an amount of cash) that the Fund specifies each day.

Tax Information

The Fund intends to make distributions that may be taxable to you as ordinary income or capital gains, unless you are investing through a tax-deferred arrangement such as a 401(k) plan or an IRA.

Payments to Broker-Dealers and other Financial Intermediaries

If you purchase shares of the Fund through a broker-dealer or other financial intermediary (such as a bank), BFA or other related companies may pay the intermediary for marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems or other services related to the sale or promotion of the Funds. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Funds over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.

iShares S&P Target Date 2045 Index Fund

iShares S&P Target Date 2045 Index Fund

Ticker: TZW Stock Exchange: NYSE Arca

Investment Objective

The iShares S&P Target Date 2045 Index Fund (the “Fund”) seeks investment results that correspond generally to the price and yield performance, before fees and expenses, of the S&P Target Date 2045 Index (the “Underlying Index”).

Fees and Expenses

The following table describes the fees and expenses that you will incur if you own shares of the Fund. The investment advisory agreement between iShares Trust (the “Trust”) and BlackRock Fund Advisors (“BFA”) (the “Investment Advisory Agreement”) provides that BFA will pay all operating expenses of the Fund, except interest expenses, taxes, brokerage expenses, future distribution fees or expenses, and extraordinary expenses. “Acquired Fund Fees and Expenses” reflect the Fund’s pro rata share of the fees and expenses incurred by investing in other investment companies. As the Fund has not commenced operations prior to the date of this prospectus, Acquired Fund Fees and Expenses are based on an estimate of the Fund’s allocation to underlying funds. The impact of Acquired Fund Fees and Expenses will be included in the total returns of the Fund. Acquired Fund Fees and Expenses are not used to calculate the Fund’s net asset value per share (“NAV”) and, once included, will not be included in the calculation of the ratio of expenses to average net assets shown in the Financial Highlights section of the Fund’s prospectus (the “Prospectus”). BFA has contractually agreed to waive a portion of the advisory fee it is entitled to receive from the Fund due to its investments in other iShares funds, in an amount equal to 0.14%, through June 30, 2013. The contractual waiver may be terminated prior to June 30, 2013 only upon written agreement of the Trust and BFA.

You will also incur usual and customary brokerage commissions when buying or selling shares of the Fund, which are not reflected in the example that follows:

Portfolio Turnover. The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance.

Principal Investment Strategies

The Fund is a fund of funds and seeks its investment objective by investing primarily in the securities of other iShares funds (each, an “Underlying Fund” and collectively, the “Underlying Funds”) that themselves seek investment results corresponding to their own underlying index. The Underlying Funds invest primarily in distinct asset classes, such as large-capitalization U.S. equity, mid-capitalization U.S. equity, emerging market securities, the aggregate bond market or the U.S. Treasury bond market; each such asset class has its own risk profile.

The retirement time horizon, also referred to as a “target date,” is included in the name of an underlying index and a fund that invests in the securities of such underlying index. A fund whose index name refers to a particular target date is designed for investors expecting to retire or to begin to gradually withdraw their money around such target date.

The Underlying Index seeks to represent asset allocations for investors with a target retirement horizon on or around 2050, but only you can determine whether or not the Fund’s asset allocation reflects your risk tolerance and investment needs. The Fund may not be appropriate for all investors with this target retirement horizon. The Underlying Index’s asset allocation may continue to grow more conservative after the target date. The Fund will continue to be exposed to risk of loss after the target date. There is no guarantee that the Fund will provide adequate income through your retirement.

The Fund is designed to broadly meet the investment objectives of investors with an approximate 2050 target retirement horizon by tracking the Underlying Index. As of September 30, 2011, the Fund invested approximately 92.00% of its assets in Underlying Funds that invest primarily in equity securities, 7.64% of its assets in Underlying Funds that invest primarily in fixed-income

S-36

securities and the remainder of its assets in Underlying Funds that invest primarily in money market instruments.

As of September 30, 2011, the Fund invested in the iShares S&P 500 Index Fund, iShares S&P MidCap 400 Index Fund, iShares S&P SmallCap 600 Index Fund, iShares Cohen & Steers Realty Majors Index Fund, iShares MSCI EAFE Index Fund, iShares MSCI Emerging Markets Index Fund, iShares Barclays Aggregate Bond Fund, iShares Barclays Short Treasury Bond Fund, iShares iBoxx $ High Yield Corporate Bond Fund and BlackRock Cash Funds. BFA may add, eliminate or replace any and/or all Underlying Funds at any time.

BFA uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to “beat” the index it tracks and does not seek temporary defensive positions when markets decline or appear overvalued.

Indexing may eliminate the chance that the Fund will substantially outperform the Underlying Index but also may reduce some of the risks of active management, such as poor security selection. Indexing seeks to achieve lower costs and better after-tax performance by keeping portfolio turnover low in comparison to actively managed investment companies.

BFA uses a representative sampling indexing strategy to manage the Funds. “Representative sampling” is an indexing strategy that involves investing in a representative sample of securities that collectively has an investment profile similar to the Underlying Index. The securities selected are expected to have, in the aggregate, investment characteristics (based on factors such as market capitalization and industry weightings), fundamental characteristics (such as return variability and yield) and liquidity measures similar to those of the Underlying Index. The Fund may or may not hold all of the securities in the Underlying Index.

The Fund generally invests at least 90% of its assets in securities of the Underlying Index. The Fund may invest the remainder of its assets in securities not included in the Underlying Index, but which BFA believes will help the Fund track its Underlying Index and in other investments including futures contracts, options on futures contracts and options, as well as cash and cash equivalents, including shares of money market funds affiliated with BFA or its affiliates, to the extent permitted under the Investment Company Act of 1940, as amended (the “1940 Act”).

The Fund may lend securities representing up to one-third of the value of the Fund’s total assets (including the value of the collateral received).

The Underlying Index is sponsored by an organization (the “Index Provider”) that is independent of the Fund and BFA. The Index Provider determines the composition and relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index. The Fund’s Index Provider is Standard & Poor’s Financial Services LLC (a subsidiary of The McGraw-Hill Companies) (“S&P”).

Industry Concentration Policy. The Fund will concentrate its investments (i.e., hold 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. For purposes of this limitation, securities ofthe U.S. government (including its agencies and instrumentalities) and repurchase agreements collateralized by U.S. government securities are not considered to be issued by members of any industry.

Summary of Principal Risks

As with any investment, you could lose all or part of your investment in the Fund, and the Fund’s performance could trail that of other investments. The Fund is subject to the principal risks noted below (either directly or through its investments in the Underlying Funds), any of which may adversely affect the Fund’s NAV, trading price, yield, total return and ability to meet its investment objective.

Asset Class Risk. Securities in the Underlying Index or in the Fund’s portfolio may underperform in comparison to the general securities markets or other asset classes.

Consumer Discretionary Sector Risk. The consumer discretionary sector may be affected by changes in domestic and international economies, exchange and interest rates, competition, consumers’ disposable income and consumer preferences, social trends and marketing campaigns.

Credit Risk. The risk that debt issuers and other counterparties may not honor their obligations or may have their debt downgraded by ratings agencies.

Equity Securities Risk. Equity securities are subject to changes in value and their values may be more volatile than other asset classes.

Financial Sector Risk. Performance of companies in the financial sector may be adversely impacted by many factors, including, among others, government regulations, economic conditions, credit rating downgrades, changes in interest rates, and decreased liquidity in credit markets. This sector has experienced significant losses in the recent past, and the impact of more stringent capital requirements and of recent or future regulation on any individual financial company or on the sector as a whole cannot be predicted.

Health Care Sector Risk. The health care sector may be affected by government regulations and government health care programs, increases or decreases in the cost of medical products and services and product liability claims, among other factors. Many health care companies are heavily dependent on patent protection and the expiration of a patent may adversely affect their profitability. Health care companies are subject to competitive forces that may result in price discounting, and may be thinly capitalized and susceptible to product obsolescence.

Industrials Sector Risk. The industrials sector is affected by changes in the supply and demand for products and services, product obsolescence, claims for environmental damage or product liability and general economic conditions, among other factors.

Information Technology Sector Risk. Information technology companies face intense competition and potentially rapid product obsolescence. They are also heavily dependent on intellectual property rights and may be adversely affected by loss or impairment of those rights.

Interest Rate Risk. An increase in interest rates may cause the value of fixed-income securities held by the Fund or an Underlying Fund to decline.

Issuer Risk. Fund performance depends on the performance of individual securities to which the Fund or an Underlying Fund has

S-37

exposure. Changes to the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA’s investment management strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares, losses from trading in secondary markets, periods of high volatility and disruption in the creation/redemption process of the Fund. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV.

Model Risk. Neither the Fund nor BFA can offer assurances that the Underlying Index’s allocation model will maximize returns or minimize risk, or be appropriate for every investor seeking a particular risk profile.

Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers are subject to the risks associated with investing in those non-U.S. markets, such as heightened risks of inflation or nationalization. The Fund may lose money due to political, economic and geographic events affecting a non-U.S. issuer or market.

Passive Investment Risk. The Fund is not actively managed and BFA does not attempt to take defensive positions under any market conditions, including declining markets.

Reinvestment Risk. The Fund or an Underlying Fund invests in short-term fixed-income instruments and may be adversely affected if interest rates fall because it may invest in lower yielding bonds as bonds in the portfolio mature.

Risk of Investing in Russia. Investing in Russian securities involves significant risks, including legal, regulatory and economic risks that are specific to Russia. In addition, investing in Russian securities involves risks associated with the settlement of portfolio transactions and loss of the Fund’s ownership rights in its portfolio securities, as a result of the system of share registration and custody in Russia.

Securities Lending Risk. The Fund or an Underlying Fund may engage in securities lending. Securities lending involves the risk that the Fund or an Underlying Fund may lose money because the borrower of the Fund’s loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Tracking Error Risk. The performance of the Fund may diverge from that of the Underlying Index. Because the Fund employs a representative sampling strategy, the Fund may experience tracking error to a greater extent than a fund that seeks to replicate an index.

Valuation Risk. The value of the securities in the Fund’s portfolio may change on days when shareholders will not be able to purchase or sell the Fund’s shares.

Performance Information

As of the date of the Prospectus, the Fund has been in operation for less than one full calendar year and therefore does not report its performance information.

Management

Investment Adviser. BlackRock Fund Advisors.

Portfolio Managers. Rene Casis, Diane Hsiung and Greg Savage (the “Portfolio Managers”) are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager supervises a portfolio management team. Mr. Casis, Ms. Hsiung and Mr. Savage have been Portfolio Managers of the Fund since inception.

Purchase and Sale of Fund Shares

The Fund is an exchange-traded fund (commonly referred to as an “ETF”). Individual Fund shares may only be purchased and sold on a national securities exchange through a broker-dealer. The price of Fund shares is based on market price, and because ETF shares trade at market prices rather than NAV, shares may trade at a price greater than NAV (a premium) or less than NAV (a discount). The Fund will only issue or redeem shares that have been aggregated into blocks of 50,000 shares or multiples thereof (“Creation Units”) to authorized participants who have entered into agreements with the Fund’s distributor. The Fund will issue or redeem Creation Units in return for a designated portfolio of securities (and an amount of cash) that the Fund specifies each day.

Tax Information

The Fund intends to make distributions that may be taxable to you as ordinary income or capital gains, unless you are investing through a tax-deferred arrangement such as a 401(k) plan or an investment retirement account (“IRA”).

Payments to Broker-Dealers and other Financial Intermediaries

If you purchase shares of the Fund through a broker-dealer or other financial intermediary (such as a bank), BFA or other related companies may pay the intermediary for marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems or other services related to the sale or promotion of the Funds. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Funds over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.

More Information About the Funds

This Prospectus contains important information about investing in the Funds. Please read this Prospectus carefully before you make any investment decisions. Additional information regarding the Funds is available at www.iShares.com.

BFA is the investment adviser to the Funds. Shares of each Fund are listed for trading on NYSE Arca, Inc. (“NYSE Arca”). The market price for a share of a Fund may be different from the Fund’s most recent NAV. Each Fund has its own CUSIP number and exchange trading symbol.

ETFs are funds that trade like other publicly-traded securities and are designed to track an index. Similar to shares of an index mutual fund, each share of a Fund represents a partial ownership in an underlying portfolio of securities intended to track a market index. Unlike shares of a mutual fund, which can be bought and redeemed from the issuing fund by all shareholders at a price based on NAV, shares of the Funds may be purchased or redeemed directly from the Funds at NAV solely by authorized participants. Also unlike shares of a mutual fund, shares of each Fund are listed on a national securities exchange and trade in the secondary market at market prices that change throughout the day.

An index is a theoretical financial calculation while each Fund is an actual investment portfolio. The performance of each Fund and its Underlying Index may vary due to transaction costs, non-U.S. currency valuations, asset valuations, corporate actions (such as mergers and spin-offs), timing variances and differences between each Fund’s portfolio and its Underlying Index resulting from legal restrictions (such as diversification requirements) that apply to each Fund but not to its Underlying Index or to the use of representative sampling. “Tracking error” is the difference between the performance (return) of each Fund’s portfolio and that of its Underlying Index. BFA expects that, over time, each Fund’s tracking error will not exceed 5%. Because each Fund uses a representative sampling indexing strategy, it can be expected to have a larger tracking error than if it used a replication indexing strategy. “Replication” is an indexing strategy in which a fund invests in substantially all of the securities in its underlying index in approximately the same proportions as in the underlying index.

An investment in a Fund is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, BFA or any of its affiliates.

Each Fund’s investment objective and its Underlying Index may be changed without shareholder approval.

Each Fund may make commodity-related investments through investments in a wholly-owned subsidiary of the Fund formed in the Cayman Islands (the “Subsidiary”). The Subsidiary is managed by BFA. The assets of the Subsidiary are subject to the same investment restrictions and limitations, and follow the same compliance policies and procedures, as the Fund. The Fund will not invest more than 25% of its total assets (measured at the time of investment) in the Subsidiary.

Investment Objectives of the Funds

Each Fund seeks investment results that correspond generally to the price and yield performance, before fees and expenses, of its Underlying Index. Each Underlying Index is comprised entirely of securities of its Underlying Funds that themselves seek investment results that correspond generally to the price and yield performance, before fees and expenses, of their own respective underlying indexes. Each Fund is an ETF fund of funds and seeks its investment objective by investing primarily in the Underlying Funds.

The Underlying Indexes are designed to provide exposure to a diversified array of financial assets, as well as to the investment opportunity generally available in target date funds. Each year, S&P conducts a survey of target date funds and combines the raw survey data to derive an allocation strategy for each of the Underlying Indexes. The Underlying Indexes are designed to correspond to the asset class exposures identified in S&P’s survey process. Each Underlying Index is representative of the opportunity available to investors for a particular retirement time horizon.

The retirement time horizon, also referred to as a “target date,” is included in the name of an Underlying Index and a Fund that invests in the securities of such Underlying Index. A Fund whose index name refers to a particular target date is designed for investors expecting to retire or to begin to gradually withdraw their money around such target date. Thus, for example, the iShares S&P Target Date 2015 Index Fund invests in securities represented in the S&P Target Date 2015 Index and is designed for investors who retire in approximately the year 2015. However, because the index represents a blend of different target date methodologies, each Fund is not designed in anticipation of a specific rate of withdrawal.

Note: The preceding chart is for illustrative purposes only and represents the actual allocation percentages of each Fund as of September 30, 2011, which are subject to change. The chart is intended to show that, over time, the investment mix of each Fund gradually shifts from a greater concentration in higher-risk investments (i.e., equity securities) to a greater concentration in lower-risk investments (i.e., fixed-income securities).

A Further Discussion of Principal Risks

Each Fund is subject to various risks, including the principal risks noted below, any of which may adversely affect the Fund’s NAV, trading price, yield, total return and ability to meet its investment objective. Each Fund may be exposed to these risks directly, or indirectly through the Fund’s investments in the Underlying Funds. You could lose all or part of your investment in the Funds, and the Funds could underperform other investments.

Asset Class Risk. The securities in an Underlying Index or a Fund’s or Underlying Fund’s portfolio may underperform the returns of other securities or indexes that track other industries, groups of industries, markets, asset classes or sectors. Various types of securities or indexes tend to experience cycles of outperformance and underperformance in comparison to the general securities markets.

Consumer Discretionary Sector Risk. The success of consumer product manufacturers and retailers is tied closely to the performance of domestic and international economies, interest rates, exchange rates, competition, consumer confidence, changes in demographics and consumer preferences. Companies in the consumer discretionary sector depend heavily on disposable household income and consumer spending, and may be strongly affected by social trends and marketing campaigns. These companies may be subject to severe competition, which may have an adverse impact on their profitability.

Credit Risk. Credit risk is the risk that an issuer or guarantor of debt instruments or the counterparty to a derivatives contract, repurchase agreement or loan of portfolio securities will be unable or unwilling to make its timely interest and/or principal payments or to otherwise honor its obligations. Debt instruments are subject to varying degrees of credit risk, which may be reflected in their credit ratings. There is the chance that any of an Underlying Fund’s portfolio holdings will have their credit ratings downgraded or will default (fail to make scheduled interest or principal payments), potentially reducing such Underlying Fund’s income level or share price, which can adversely affect the value of Funds that invest in such Underlying Fund.

Equity Securities Risk. Certain Underlying Funds invest in equity securities, which are subject to changes in value that may be attributable to market perception of a particular issuer or to general stock market fluctuations that affect all issuers. Investments in equity securities may be more volatile than investments in other asset classes.

Financial Sector Risk. Companies in the financial sector of an economy are often subject to governmental regulation and, recently, government intervention and the potential for additional regulation, which may adversely affect the scope of their activities, the prices they can charge and the amount of capital they must maintain. Governmental regulation may change frequently and may have significant adverse consequences for companies in the financial sector, including effects not intended by such regulation. The impact of recent or future regulation in various countries on any individual financial company or on the sector as a whole cannot be predicted. Certain risks may impact the value of investments in the financial sector more severely than investments outside this sector, including the risks associated with companies that operate with substantial financial leverage. Companies in the financial sector may also be adversely affected by increases in interest rates and loan losses, decreases in the availability of money or asset valuations, credit rating downgrades and adverse conditions in other related markets. Over the past few years, the deterioration of the credit markets has impacted a broad range of mortgage, asset-backed, auction rate, sovereign debt and other markets, including U.S. and non-U.S. credit and interbank money markets, thereby affecting a wide range of financial institutions and markets. This situation has created instability in the financial markets and caused certain financial companies to incur large losses. Some financial companies have experienced declines in the valuations of their assets, taken actions to raise capital (such as the issuance of debt or equity securities), or even ceased operations. Some financial companies have borrowed significant amounts of capital from governments and may face future government-imposed restrictions on their businesses or increased government intervention. These actions have caused the securities of many financial companies to decline in value. Insurance companies, in particular, may be subject to severe price competition, which may have an adverse impact on their profitability.

Health Care Sector Risk. The profitability of companies in the health care sector may be affected by extensive government regulations, restrictions on government reimbursement for medical expenses, rising costs of medical products and services, pricing pressure, an increased emphasis on outpatient services, limited number of products, industry innovation, changes in technologies and other market developments. Many health care companies are heavily dependent on patent protection. The expiration of patents may adversely affect the profitability of these companies. Many health care companies are subject to extensive litigation based on product liability and similar claims. Health care companies are subject to competitive forces that may make it difficult to raise prices and, in fact, may result in price discounting. Many new products in the health care sector may be subject to regulatory approvals. The process of obtaining such approvals may be long and costly. Companies in the health care sector may be thinly capitalized and may be susceptible to product obsolescence.

Industrials Sector Risk. The stock prices of companies in the industrials sector are affected by supply and demand, both for their specific product or service and for industrials sector products in general. The products of manufacturing companies may face obsolescence due to rapid technological developments and frequent new product introduction. Government regulations, world events, economic conditions and exchange rates affect the performance of companies in the industrials sector. Companies in the industrials sector may be adversely affected by liability for environmental damage and product liability claims.

Information Technology Sector Risk. Information technology companies face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Like other technology companies, information technology companies may have limited product lines, markets, financial resources or personnel. The products of information technology companies may face obsolescence due to rapid technological developments and frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Companies in the information technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies.

Interest Rate Risk. As interest rates rise, the value of a fixed-income security held by an Underlying Fund is likely to decrease. Securities with longer durations tend to be more sensitive to interest rate changes, usually making them more volatile than securities with shorter durations. To the extent an Underlying Fund invests a substantial portion of its assets in fixed-income securities with longer-term maturities, rising interest rates may cause the value of such Underlying Fund’s investments to decline significantly, which can adversely affect the value of Funds that invest in such Underlying Fund. Prices of bonds may fall because of a rise in interest rates.

Issuer Risk. The performance of each Fund depends on the performance of individual securities to which the Fund has exposure. Any issuer of these securities may perform poorly, causing the value of its securities to decline. Poor performance may be caused by poor management decisions, competitive pressures, changes in technology, expiration of patent protection, disruptions in supply, labor problems or shortages, corporate restructurings, fraudulent disclosures or other factors. Issuers may, in times of distress or at their own discretion, decide to reduce or eliminate dividends, which may also cause their stock prices to decline.

Management Risk. Each Fund may not fully replicate its Underlying Index and may hold securities not included in its Underlying Index. As a result, a Fund is subject to the risk that BFA’s investment management strategy, the implementation of which is subject to a number of constraints, may not produce the intended results.

Market Risk. Each Fund could lose money due to short-term market movements and over longer periods during market downturns. Securities may decline in value due to factors affecting securities markets generally or particular industries represented in the markets. The value of a security may decline due to general market conditions, economic trends or events that are not specifically related to the issuer of the security or to factors that affect a particular industry or industries. During a general downturn in the securities markets, multiple asset classes may be negatively affected.

Market Trading Risk

Absence of Active Market. Although shares of the Funds are listed for trading on one or more stock exchanges, there can be no assurance that an active trading market for such shares will develop or be maintained.

Risk of Secondary Listings. The Funds’ shares may be listed or traded on U.S. and non-U.S. stock exchanges other than the U.S. stock exchange where the Fund’s primary listing is maintained. There can be no assurance that the Funds’ shares will continue to trade on any such

stock exchange or in any market or that the Funds’ shares will continue to meet the requirements for listing or trading on any exchange or in any market. The Funds’ shares may be less actively traded in certain markets than others, and investors are subject to the execution and settlement risks and market standards of the market where they or their broker direct their trades for execution. Certain information available to investors who trade Fund shares on a U.S. stock exchange during regular U.S. market hours may not be available to investors who trade in other markets, which may result in secondary market prices in such markets being less efficient.

Secondary Market Trading Risk. Shares of a Fund may trade in the secondary market at times when the Funds do not accept orders to purchase or redeem shares. At such times, shares may trade in the secondary market with more significant premiums or discounts than might be experienced at times when the Funds accept purchase and redemption orders.

Secondary market trading in Fund shares may be halted by a stock exchange because of market conditions or other reasons. In addition, trading in Fund shares on a stock exchange or in any market may be subject to trading halts caused by extraordinary market volatility pursuant to “circuit breaker” rules on the stock exchange or market. There can be no assurance that the requirements necessary to maintain the listing or trading of Fund shares will continue to be met or will remain unchanged.

Shares of each Fund May Trade at Prices Other Than NAV. Shares of each Fund trade on stock exchanges at prices at, above or below their most recent NAV. The NAV of each Fund is calculated at the end of each business day and fluctuates with changes in the market value of such Fund’s holdings since the most recent calculation. The trading prices of a Fund’s shares fluctuate continuously throughout trading hours based on market supply and demand rather than NAV. The trading prices of a Fund’s shares may deviate significantly from NAV during periods of market volatility. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO A FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV. However, because shares can be created and redeemed in Creation Units at NAV (unlike shares of many closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their NAVs), BFA believes that large discounts or premiums to the NAV of a Fund are not likely to be sustained over the long-term. While the creation/redemption feature is designed to make it likely that a Fund’s shares normally will trade on stock exchanges at prices close to the Fund’s next calculated NAV, exchange prices are not expected to correlate exactly with a Fund’s NAV due to timing reasons as well as market supply and demand factors. In addition, disruptions to creations and redemptions or extreme market volatility may result in trading prices for shares of a Fund that differ significantly from its NAV.

Costs of Buying or Selling Fund Shares. Buying or selling Fund shares on an exchange involves two types of costs that apply to all securities transactions. When buying or selling shares of a Fund through a broker, you will likely incur a brokerage commission or other charges imposed by brokers as determined by that broker. In addition, you may incur the cost of the “spread” – that is, the difference between what investors are willing to pay for Fund shares (the “bid” price) and the price at which they are willing to sell Fund shares (the “ask” price). Because of the costs inherent in buying or selling Fund shares, frequent trading may detract significantly from investment results and an investment in Fund shares may not be advisable for investors who anticipate regularly making small investments.

Model Risk. Neither the Funds nor BFA can offer any assurance that the allocation model used to calculate the Underlying Indexes will either maximize returns or minimize risks in accordance with the targeted time horizon for each Underlying Index, nor can the Funds or BFA offer assurance that a particular allocation will be the appropriate allocation in all circumstances for every investor seeking a particular risk profile or time horizon.

Mortgage-Backed Securities Risk. Certain Underlying Funds invest in MBS issued by the Federal National Mortgage Association (“FNMA”), the Government National Mortgage Association (“GNMA”) or the Federal Home Loan Mortgage Corporation (“FHLMC”). While securities issued by GNMA are backed by the full faith and credit of the U.S. government, securities issued by FNMA and FHLMC are not backed by the full faith and credit of the U.S. government, and there can be no assurance that the U.S. government would provide financial support to its agencies or instrumentalities where it is not obligated to do so.

MBS are subject to prepayment risk, which is the risk that during periods of falling interest rates, an issuer of mortgages and other securities may be able to repay principal prior to the security’s maturity causing a Fund to have to reinvest in securities with a lower yield, resulting in a decline to a Fund’s income.

MBS are also subject to extension risk, which is the risk that when interest rates rise, certain MBS will be paid off substantially more slowly than originally anticipated and the value of those securities may fall sharply, resulting in a decline to the Fund’s income and potentially in the value of a Fund’s investments.

Because of prepayment and extension risk, MBS react differently to changes in interest rates than other bonds. Small movements in interest rates (both increases and decreases) may quickly and significantly reduce the value of certain MBS.

In recent years, the market for MBS experienced substantially lower valuations and greatly reduced liquidity. Ongoing economic and market uncertainty suggests that MBS may continue to be more difficult to value and to dispose of than previously.

Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers are subject to all of the risks of investing in the markets where such issuers are located, including heightened risks of inflation or nationalization and market fluctuations caused by economic and political developments. As a result of investing in non-U.S. securities, the Underlying Funds that invest in foreign securities may be subject to increased risk of loss caused by any of the factors listed below:

  • Lower levels of liquidity and market efficiency;
  • Greater securities price volatility;
  • Exchange rate fluctuations and exchange controls;
  • Less availability of public information about issuers;
  • Limitations on foreign ownership of securities;
  • Imposition of withholding or other taxes;
  • Imposition of restrictions on the expatriation of the funds or other assets of an Underlying Fund;
  • Higher transaction and custody costs and delays in settlement procedures;
  • Difficulties in enforcing contractual obligations;
  • Lower levels of regulation of the securities market;
  • Weaker accounting, disclosure and reporting requirements; and
  • Legal principles related to corporate governance, directors’ fiduciary duties and liabilities and stockholders’ rights in markets in which the Underlying Funds may invest may differ and/or may not be as extensive or protective as those that apply in the United States.

Passive Investment Risk. The Funds and Underlying Funds are not actively managed and may be affected by a general decline in market segments related to their Underlying Indexes. Each Fund and Underlying Fund invests in securities included in, or representative of, its Underlying Index regardless of their investment merits. BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

Real Estate Company Risk. An Underlying Fund that invests in companies that invest in real estate, such as a real estate investment trust (“REIT”) or real estate holding companies (collectively, “Real Estate Companies”) is exposed to unique risks that relate specifically to the way in which Real Estate Companies are organized and operated. Real estate is a cyclical business, highly sensitive to general and local economic conditions and developments, and characterized by intense competition and periodic overbuilding.

Interest Rate Risk. Rising interest rates could result in higher costs of capital for Real Estate Companies, which could negatively impact a Real Estate Company’s ability to meet its payment obligations.

Leverage Risk. Real Estate Companies may use leverage (and some may be highly leveraged), which increases investment risk and could adversely affect a Real Estate Company’s operations and market value in periods of rising interest rates as well as risks normally associated with debt financing. Financial covenants related to a Real Estate Company’s leveraging may affect the ability of the Real Estate Company to operate effectively. In addition, real property may be subject to the quality of credit extended and defaults by borrowers and tenants. If the properties do not generate sufficient income to meet operating expenses, including, where applicable, debt service, ground lease payments, tenant improvements, third-party leasing commissions and other capital expenditures, the income and ability of a Real Estate Company to make payments of any interest and principal on its debt securities will be adversely affected.

Property Risk. Real Estate Companies may be subject to risks relating to functional obsolescence or reduced desirability of properties; extended vacancies due to economic conditions and tenant bankruptcies; catastrophic events such as earthquakes, hurricanes and terrorist acts; and casualty or condemnation losses. Real estate income and values also may be greatly affected by demographic trends, such as population shifts or changing tastes and values, or increasing vacancies or declining rents resulting from legal, cultural, technological, global or local economic developments.

Management Risk. Real Estate Companies are dependent upon management skills and may have limited financial resources. Real Estate Companies are generally not diversified and may be subject to heavy cash flow dependency, default by borrowers and self-liquidation. In addition, transactions between Real Estate Companies and their affiliates may be subject to conflicts of interest, which may adversely affect a Real Estate Company’s shareholders. A Real Estate Company may also have joint venture investments in certain of its properties and, consequently, its ability to control decisions relating to such properties may be limited.

Liquidity Risk. Investing in Real Estate Companies may involve risks similar to those associated with investing in small-capitalization companies. Real Estate Company securities, like the securities of other smaller companies, may be more volatile than, and perform differently from, shares of large capitalization companies. There may be less trading in Real Estate Company shares, which means that buy and sell transactions in those shares could have a magnified impact on share price, resulting in abrupt or erratic price fluctuations. In addition, real estate is relatively illiquid and, therefore, a Real Estate Company may have a limited ability to vary or liquidate properties in response to changes in economic or other conditions.

Concentration Risk. Real Estate Companies may lack diversification, due to ownership of a limited number of properties and concentration in a particular geographic region or property type.

U.S. Tax Risk. Certain U.S. Real Estate Companies are subject to special U.S. federal tax requirements. A REIT that fails to comply with such tax requirements may be subject to U.S. federal income taxation, which may affect the value of the REIT and the characterization of the REIT’s distributions. The U.S. federal tax requirement that a REIT distribute substantially all of its net income to its shareholders may result in a REIT having insufficient capital for future expenditures.

Regulatory Risk. Real estate income and values may be adversely affected by such factors as applicable domestic and foreign laws (including tax laws). Government actions, such as tax increases, zoning law changes or environmental regulations, also may have a major impact on real estate.

Reinvestment Risk. An Underlying Fund that invests mostly in short-term fixed-income instruments may be adversely affected when interest rates fall because it may invest in lower yielding bonds as bonds in its portfolio mature. This may cause the Underlying Fund’s income to decline, which may adversely affect the value of the Fund that invest in such Underlying Fund.

Risk of Investing in Russia. Investing in Russian securities involves significant risks, in addition to those described under “Emerging Markets Risk” and “Non-U.S. Securities Risk” that are not typically associated with investing in U.S. securities, including:

  • the risk of delays in settling portfolio transactions and the risk of loss arising out of the system of share registration and custody used in Russia;
  • risks in connection with the maintenance of a Fund’s portfolio securities and cash with foreign subcustodians and securities depositories, including the risk that appropriate sub-custody arrangements will not be available to the Fund;
  • the risk that a Fund’s ownership rights in portfolio securities could be lost through fraud or negligence as a result of the fact that ownership in shares of Russian companies is recorded by the companies themselves and by registrars, rather than by a central registration system; and
  • the risk that a Fund may not be able to pursue claims on behalf of its shareholders because of the system of share registration and custody, and because Russian banking institutions and registrars are not guaranteed by the government.

Securities Lending Risk. The Funds or the Underlying Funds may engage in securities lending. Securities lending involves the risk that the Funds or the Underlying Funds may lose money because the borrower of the Fund’s or Underlying Fund’s loaned securities fails to return the securities in a timely manner or at all. The Funds could also lose money in the event of a decline in the value of the collateral provided for the loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Funds.

Subsidiary Risk. To the extent the Funds may invest in a Subsidiary, each Fund is indirectly exposed to the risks associated with the Subsidiary’s investments. The commodity-related instruments that may be held by the Subsidiaries are generally similar to those that are permitted to be held by each Fund and are subject to the same risks that apply to similar investments if held directly by each Fund. There can be no assurance that the investment objective of the Subsidiaries will be achieved. The Subsidiaries are not registered under the 1940 Act, and, unless otherwise noted in this prospectus, are not subject to all the investor protections of the 1940 Act. The Board has oversight responsibility for the investment activities of each Fund, including its investment in the Subsidiaries, and each Fund’s role as sole shareholder of the Subsidiaries. The Subsidiaries will be subject to the same investment restrictions and limitations, and will follow the same compliance policies and procedures, as each Fund.

Each Fund has requested a private letter ruling from the U.S. Internal Revenue Service (“IRS”) confirming that the annual net profit, if any, realized by its Subsidiary and imputed for income tax purposes to the Fund will constitute “qualifying income” for purposes of the Fund remaining qualified as a regulated investment company for U.S. federal income tax purposes. The IRS has indicated that the granting of private letter rulings, like the one requested by each Fund, is currently suspended, pending further internal discussion. As a result, there can be no assurance that the IRS will grant the private letter ruling requested. If the IRS does not grant the private letter ruling request, there is a risk that the IRS could assert that the annual net profit realized by a Subsidiary and imputed for income tax purposes to a Fund will not be considered “qualifying income” for purposes of the Fund remaining qualified as a regulated investment company for U.S. federal income tax purposes. If a Fund fails to receive a private letter ruling, it may elect not to form or invest through a Subsidiary. Such an occurence may, in turn, reduce a Fund’s ability to gain investment exposure to commodities and track the performance of its Underlying Index. Moreover, changes in the laws of the United States and/or the Cayman Islands could result in the inability of each Fund and/or the Subsidiaries to operate as described in this prospectus and the SAI and could adversely affect each Fund. For example, the Cayman Islands does not currently impose any income, corporate or capital gains taxes, estate duty, inheritance tax, gift tax or withholding tax on the Subsidiaries. If Cayman Islands law changes such that the Subsidiaries must pay Cayman Islands taxes, Fund shareholders would likely experience decreased investment returns.

Tracking Error Risk. Imperfect correlation between a Fund’s or Underlying Fund’s portfolio securities and those in its Underlying Index, rounding of prices, changes to its Underlying Index and regulatory requirements may cause tracking error, which is the divergence of a Fund’s performance from that of its Underlying Index. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because a Fund or Underlying Fund incurs fees and expenses, while its Underlying Index does not. Due to certain adverse tax consequences that may result from a Fund investing directly in commodities, each Fund may reduce its exposure to commodities to an amount below the current commodity exposure, if any, of its Underlying Index. This reduced commodity exposure, in turn, might result in, or exacerbate, a difference between the performance of the Fund and the performance of the Underlying Index. If a Fund receives a private letter ruling from the IRS, the Fund is expected to adjust its exposure to commodities in order to more closely align the holdings of the Fund with its Underlying Index. Because the Fund employs a representative sampling strategy, the Fund may experience tracking error to a greater extent than a fund that seeks to replicate an index.

Treasury Obligations Risk. Treasury obligations may differ from other issuances in their interest rates, maturities, times of issuance and other characteristics. Similar to other issuers, changes to the financial condition or credit rating of a government may cause the value of a Fund’s Treasury obligations to decline. On August 5, 2011, S&P downgraded U.S. Treasury securities from AAA rating to AA+. A downgrade of the ratings of U.S. government debt obligations, which are often used as a benchmark for other borrowing arrangements, could result in higher interest rates for individual and corporate borrowers, cause disruptions in the international bond markets and generally have a substantial negative effect on the U.S. economy. A downgrade of Treasury securities from another ratings agency or a further downgrade beyond AA+ rating byS&P may cause the value of a Fund’s Treasury obligations to decline.

Valuation Risk. Because non-U.S. exchanges may be open on days when an Underlying Fund does not price its shares, the value of the securities in an Underlying Fund’s portfolio may change on days when the Funds will not be able to purchase or sell an Underlying Fund’s shares. In addition, for purposes of calculating a Fund’s NAV, the value of assets denominated in non-U.S. currencies is converted into U.S.

dollars using exchange rates deemed appropriate by BFA. This conversion may result in a difference between the prices used to calculate the Fund’s NAV and the prices used by its Underlying Index, which, in turn, could result in a difference between the Fund’s performance and the performance of the Underlying Index.

A Further Discussion of Other Risks

Each Fund may also be subject to certain other risks associated with its investments and investment strategies.

Asian Economic Risk. Certain Asian economies have experienced over-extension of credit, currency devaluations and restrictions, high unemployment, high inflation, decreased exports and economic recessions. Economic events in any one Asian country may have a significant economic effect on the entire Asian region, and on some or all of the countries in which the Funds or the Underlying Funds may invest.

Consumer Staples Sector Risk. The consumer staples sector may be affected by the permissibility of using various food additives and production methods, marketing campaigns and other factors affecting consumer demand. Tobacco companies, in particular, may be adversely affected by new laws, regulations and litigation. The consumer staples sector may also be adversely affected by changes or trends in commodity prices, which may be influenced or characterized by unpredictable factors.

Energy Sector Risk. The energy sector is cyclical and highly dependent on commodities prices. The market values of companies in the energy sector are strongly affected by the levels and volatility of global energy prices, energy supply and demand, capital expenditures on exploration and production, energy conservation efforts, exchange rates and technological advances, among other factors. Companies in this sector may be subject to substantial government regulation and contractual fixed pricing, which may increase the cost of business and limit these companies’ earnings. A significant portion of their revenues depends on a relatively small number of customers, including governmental entities and utilities. As a result, governmental budget constraints may have a material adverse effect on the stock prices of companies in this industry. Energy companies may also operate in countries with less developed regulatory regimes or a history of expropriation, nationalization or other adverse policies. Energy companies also face a significant risk of civil liability from accidents resulting in injury or loss of life or property, pollution or other environmental mishaps, equipment malfunctions or mishandling of materials and a risk of loss from terrorism and natural disasters. Any such event could have serious consequences for the general population of the area affected and result in a material adverse impact on a Fund’s portfolio and the performance of the Fund. Energy companies can be significantly affected by the supply of, and demand for, specific products (e.g., oil and natural gas) and services, exploration and production spending, government regulation, world events and general economic conditions.

European Economic Risk. The Economic and Monetary Union of the European Union (the “EU”) requires member countries to comply with restrictions on inflation rates, deficits, interest rates, debt levels and fiscal and monetary controls, each of which may significantly affect every country in Europe. Decreasing imports or exports, changes in governmental or EU regulations on trade, changes in the exchange rate of the euro, the default or threat of default by an EU member country on its sovereign debt, and/or an economic recession in an EU member country may have a significant adverse effect on the economies of EU member countries and their trading partners, including some or all of the countries in which the Funds or the Underlying Funds may invest. The European financial markets have recently experienced volatility and have been adversely affected by concerns about economic downturns, credit rating downgrades, rising government debt levels and possible default on or restructuring of government debt in several European countries, including Greece, Ireland, Italy, Portugal and Spain. A default or debt restructuring by any European country would adversely impact holders of that country’s debt, and sellers of credit default swaps linked to that country’s creditworthiness, which may be located in countries other than those listed in the previous sentence. These events have adversely affected the value and exchange rate of the euro and may continue to significantly affect the economies of every country in Europe, including EU member countries that do not use the euro and non-EU member countries.

Materials Sector Risk. Companies in the materials sector could be adversely affected by commodity price volatility, exchange rates, import controls, increased competition, depletion of resources, technical progress, labor relations, exchange rates and government regulations, among other factors. Also, companies in the materials sector are at risk of liability for environmental damage and product liability claims. Production of materials may exceed demand as a result of market imbalances or economic downturns, leading to poor investment returns.

Portfolio Holdings Information

A description of the Trust’s policies and procedures with respect to the disclosure of the Funds’ portfolio securities is available in the Funds’ combined Statement of Additional Information (“SAI”). The top holdings of each Fund can be found at www.iShares.com. Fund fact sheets provide information regarding each Fund’s top holdings and may be requested by calling 1-800-iShares (1-800-474-2737).

A Further Discussion of Principal Investment Strategies

Each Fund pursues a common strategy of allocating and reallocating its assets among the Underlying Funds consistent with the allocation and reallocation among the Underlying Funds in the Underlying Index, as determined by S&P. The Funds with longer time horizons invest a greater portion of their assets in Underlying Funds that invest in equity securities, which provide a greater potential to achieve higher returns over the long-term but have a greater risk of short-term loss. In addition to investing in the Underlying Funds, each Fund may borrow, lend its portfolio securities to brokers, dealers and financial institutions, and may invest the collateral in certain short-term instruments either directly or through one or more money market funds, as described in greater detail in the Funds’ SAI.

The Funds with shorter time horizons invest a greater portion of their assets in Underlying Funds that invest in bonds and short-term instruments, which typically offer reduced risk and price volatility but forego some potential returns. Accordingly, under normal circumstances, the Funds with shorter time horizons have lower expected returns than the Funds with longer time horizons. As each Fund approaches its designated time horizon, it allocates assets more conservatively among the Underlying Funds consistent with the allocation of the Underlying Index. This systematic shift toward more conservative investments reflects the goal of target date funds in the Underlying Index to reduce the risk of significant reductions in the value of an investment in a fund as it approaches its time horizon.

For example, a Fund that has reached or passed its target date has entered its “retirement phase” and seeks to maximize returns consistent with the risk that an average investor in retirement may be willing to accept as determined by S&P’s methodology. This does not mean that the Fund invests exclusively, or primarily, in Underlying Funds that invest in money market instruments. Rather, a portion of the Fund’s assets will continue to be allocated to Underlying Funds that are equity and bond funds, in addition to Underlying Funds that invest in money market instruments. Certain Underlying Funds may invest in real estate companies, foreign securities, emerging markets and debt instruments, which are subject to additional risks, as described in this Prospectus and the SAI.

The following table lists the Underlying Funds and the asset allocation for each Fund as of September 30, 2011. BFA allocates each Fund’s assets among the Underlying Funds in accordance with the Fund’s investment objective and policies. The asset allocation for each Fund will vary over time, and BFA is not required to invest any Fund’s assets in each of the Underlying Funds or in any particular percentage in any given Underlying Fund:

In managing each of the Underlying Funds, BFA uses a representative sampling index strategy. Representative sampling is an indexing strategy that involves investing in a representative sample of securities that collectively have an investment profile similar to a specified benchmark index. Securities selected for the Underlying Funds are expected to have, in the aggregate, investment characteristics (based on factors such as market capitalization and industry weightings), fundamental characteristics (such as return variability and yield) and liquidity measures similar to those of the applicable underlying index. The Underlying Funds may or may not hold all of the securities that are included in their respective underlying index and may hold certain securities that are not included in their respective underlying indexes. Additional information regarding the Underlying Funds and their investment objectives is provided below.

The iShares S&P 500 Index Fund seeks investment results that correspond generally to the price and yield performance, before fees and expenses, of the S&P 500® . The S&P 500® measures the performance of the large-capitalization sector of the U.S. equity market.

Management

Investment Adviser. As investment adviser, BFA has overall responsibility for the general management and administration of the Trust. BFA provides an investment program for each Fund and manages the investment of each Fund’s assets. In managing the Funds, BFA may draw

upon the research and expertise of its asset management affiliates with respect to certain portfolio securities. In seeking to achieve a Fund’s investment objective, BFA uses teams of portfolio managers, investment strategists and other investment specialists. This team approach brings together many disciplines and leverages BFA’s extensive resources.

Pursuant to the Investment Advisory Agreement between BFA and the Trust (entered into on behalf of the Funds), BFA is responsible for substantially all expenses of the Funds, except interest expenses, taxes, brokerage expenses, future distribution fees or expenses and extraordinary expenses.

For its investment advisory services to each Fund, BFA is entitled to receive a management fee from each Fund based on a percentage of a Fund’s average daily net assets, at the annual rate of 0.25%. Because the iShares S&P Target Date 2045 Index Fund and the iShares S&P Target Date 2050 Index Fund have been in operation for less than one full fiscal year, this percentage reflects the rate at which BFA will be paid. BFA has entered into a Fee Waiver Agreement with the Trust, under which BFA agrees to waive a portion of the management fee that it is entitled to receive from each Fund in an amount equal to 0.14%. The Fee Waiver Agreement remains in effect until June 30, 2013. After giving effect to the fee waiver, BFA will receive a management fee based on a percentage of each Fund’s average daily net assets, at the annual rate of 0.11%. BFA will also receive additional revenue from the Underlying Funds as a result of the Funds’ investment in the Underlying Funds (the “Acquired Fund Fees and Expenses”).

BFA is located at 400 Howard Street, San Francisco, CA 94105. It is a wholly owned subsidiary of BTC, which in turn is indirectly wholly-owned by BlackRock, Inc. (“BlackRock”). As of September 30, 2011, BTC and its affiliates, including BFA and BlackRock, provided investment advisory services for assets in excess of $3.35 trillion. BFA, BTC, BlackRock Execution Services, BlackRock and their affiliates deal, trade and invest for their own accounts in the types of securities in which the Funds may also invest.

A discussion regarding the basis for the Trust’s Board of Trustees’ (the “Board”) approval of the Investment Advisory Agreement with BFA is available in each Fund’s annual report for the period ended July 31.

Portfolio Managers. Rene Casis, Diane Hsiung and Greg Savage are primarily responsible for the day-to-day management of the Funds. Each Portfolio Manager is responsible for various functions related to portfolio management, including, but not limited to, investing cash inflows, coordinating with members of his or her portfolio management team to focus on certain asset classes, implementing investment strategy, researching and reviewing investment strategy and overseeing members of his or her portfolio management team that have more limited responsibilities.

Rene Casis has been employed by BFA (formerly, Barclays Global Fund Advisors (“BGFA”)) and BTC (formerly, Barclays Global Investors, N.A. (“BGI”)) as a senior portfolio manager since 2009. From 2005 to 2009, Mr. Casis was a trader at Barclays Capital. Prior to that, Mr. Casis was a portfolio manager from 2000 to 2005 for BGFA and BGI. Mr. Casis has been a Portfolio Manager since 2010 for the iShares S&P Target Date Retirement Income Index Fund, iShares S&P Target Date 2010 Index Fund, iShares S&P Target Date 2015 Index Fund, iShares S&P Target Date 2020 Index Fund, iShares S&P Target Date 2025 Index Fund, iShares S&P Target Date 2030 Index Fund, iShares S&P Target Date 2035 Index Fund and iShares S&P Target Date 2040 Index Fund, and since inception for the iShares S&P Target Date 2045 Index Fund and iShares S&P Target Date 2050 Index Fund.

Diane Hsiung has been employed by BFA and BTC as a senior portfolio manager since 2007. Prior to that, Ms. Hsiung was a portfolio manager from 2002 to 2006 for BGFA and BGI. Ms. Hsiung has been a Portfolio Manager of each Fund since inception.

Greg Savage has been employed by BFA and BTC as a senior portfolio manager since 2006. Prior to that, Mr. Savage was a portfolio manager from 2001 to 2006 for BGFA and BGI. Mr. Savage has been a Portfolio Manager of each Fund since inception.

The Funds’ SAI provides additional information about the Portfolio Managers’ compensation, other accounts managed by the Portfolio Managers and the Portfolio Managers’ ownership (if any) of shares in the Funds.

Administrator, Custodian and Transfer Agent. State Street Bank and Trust Company (“State Street”) is the administrator, custodian and transfer agent for each Fund.

Conflicts of Interest. BFA wants you to know that there are certain entities with which BFA has relationships that may give rise to conflicts of interest, or the appearance of conflicts of interest. These entities include the following: BFA’s affiliates (including BlackRock and The PNC Financial Services Group, Inc., and each of their affiliates, directors, partners, trustees, managing members, officers and employees (collectively, the “Affiliates”)) and BlackRock’s significant shareholder, Barclays Bank PLC and its affiliates, including Barclays PLC (each, an “Entity” and together, the “Entities”).

The activities of BFA, the Affiliates and the Entities in the management of, or their interest in, their own accounts and other accounts they manage, may present conflicts of interest that could disadvantage the Funds and their shareholders. BFA and its Affiliates or the Entities provide investment management services to other funds and discretionary managed accounts that may follow an investment program similar to that of the Funds. BFA, its Affiliates and the Entities are involved worldwide with a broad spectrum of financial services and asset management activities and may engage in the ordinary course of business in activities in which their interests or the interests of their clients may conflict with those of the Funds. BFA, one or more of the Affiliates or the Entities acts, or may act, as an investor, investment banker, research provider, investment manager, financier, underwriter, advisor, market maker, trader, prime broker, lender, agent or principal, and have other direct and indirect interests, in securities, currencies and other instruments in which the Funds may directly or indirectly invests. Thus, it is likely that the Funds will have multiple business relationships with and will invest in, engage in transactions with, make voting decisions with respect to, or obtain services from, entities for which BFA, an Affiliate or an Entity performs or seeks to perform investment banking or other services.

BFA or one or more Affiliates or Entities may engage in proprietary trading and advise accounts and funds that have investment objectives similar to those of the Funds and/or that engage in and compete for transactions in the same types of securities, currencies and other instruments as the Funds, including in securities issued by other open-end and closed-end investment management companies, including investment companies that are affiliated with the Funds and BFA, to the extent permitted under the 1940 Act. The trading activities of BFA, these Affiliates and Entities are carried out without reference to positions held directly or indirectly by the Funds and may result in BFA, an Affiliate or an Entity having positions that are adverse to those of the Funds.

No Affiliate or Entity is under any obligation to share any investment opportunity, idea or strategy with the Funds. As a result, an Affiliate or an Entity may compete with the Funds for appropriate investment opportunities. As a result of this and several other factors, the results of the Funds’ investment activities may differ from those of an Affiliate or an Entity and of other accounts managed by an Affiliate or an Entity, and it is possible that the Funds could sustain losses during periods in which one or more Affiliates or Entities and other accounts achieve profits on their trading for proprietary or other accounts. The opposite result is also possible.

The Funds may, from time to time, enter into transactions in which BFA or an Affiliate’s or an Entity’s clients have an interest adverse to the Funds. Furthermore, transactions undertaken by Affiliate-advised clients may adversely impact the Funds. Transactions by one or more Affiliate- or Entity-advised clients or BFA may have the effect of diluting or otherwise disadvantaging the values, prices or investment strategies of the Funds.

An Entity may maintain securities indices as part of their product offerings. Index-based funds seek to track the performance of securities indices and may use the name of the index in the fund name. Index providers, including the Entities, may be paid licensing fees for use of their indices or index names. Entities will not be obligated to license their indices to BFA and its Affiliates, and BFA and its Affiliates will not be assured that the terms of any index licensing agreement with the Entities will be as favorable as those terms offered to other index licensees.

The Funds’ activities may be limited because of regulatory restrictions applicable to one or more Affiliates or Entities, and/or their internal policies designed to comply with such restrictions. In addition, the Funds may invest in securities of companies with which an Affiliate or an Entity has or is trying to develop investment banking relationships or in which an Affiliate or an Entity has significant debt or equity investments. The Funds also may invest in securities of companies for which an Affiliate or an Entity provides or may some day provide research coverage. An Affiliate or an Entity may have business relationships with and purchase or distribute or sell services or products from or to distributors, consultants or others who recommend the Funds or who engage in transactions with or for the Funds, and may receive compensation for such services. The Funds may also make brokerage and other payments to Affiliates or Entities in connection with the Funds’ portfolio investment transactions.

Pursuant to a securities lending program approved by the Board, the Funds have retained an Affiliate of BFA to serve as the securities lending agent for the Funds to the extent that the Funds participate in the securities lending program. For these services, the lending agent may receive a fee from the Funds, including a fee based on the returns earned on the Funds’ investment of the cash received as collateral for any loaned securities. In addition, one or more Affiliates may be among the entities to which the Funds may lend its portfolio securities under the securities lending program.

The activities of BFA, the Affiliates or Entities may give rise to other conflicts of interest that could disadvantage the Funds and their shareholders. BFA has adopted policies and procedures designed to address these potential conflicts of interest. See the Funds’ SAI for further information.

Shareholder Information

Additional shareholder information, including how to buy and sell shares of the Funds, is available free of charge by calling toll-free: 1-800-iShares (1-800-474-2737) or visiting our website at www.iShares.com.

Buying and Selling Shares. Shares of the Funds may be acquired or redeemed directly from a Fund only in Creation Units or multiples thereof, as discussed in the Creations and Redemptions section of this Prospectus. Only an Authorized Participant (as defined in the Creations and Redemptions section) may engage in creation or redemption transactions directly with the Fund. Once created, shares of the Funds generally trade in the secondary market in amounts less than a Creation Unit.

Shares of each Fund are listed on a national securities exchange for trading during the trading day. Shares can be bought and sold throughout the trading day like shares of other publicly-traded companies. The Trust does not impose any minimum investment for shares of a Fund purchased on an exchange. The Funds’ shares trade under the trading symbols listed in the Description of the Funds section of this Prospectus.

Buying or selling Fund shares on an exchange involves two types of costs that may apply to all securities transactions. When buying or selling shares of the Funds through a broker, you will likely incur a brokerage commission or other charges determined by your broker. The commission is frequently a fixed amount and may be a significant proportional cost for investors seeking to buy or sell small amounts of shares. In addition, you may incur the cost of the “spread” – that is, any difference between the bid price and the ask price. The spread varies over time for shares of each Fund based on their trading volume and market liquidity, and is generally lower if a Fund has a lot of trading volume and market liquidity, and higher if a Fund has little trading volume and market liquidity.

The Board has adopted a policy of not monitoring for frequent purchases and redemptions of Fund shares (“frequent trading”) that appear to attempt to take advantage of a potential arbitrage opportunity presented by a lag between a change in the value of a Fund’s portfolio securities after the close of the primary markets for a Fund’s portfolio securities and the reflection of that change in the Fund’s NAV (“market timing”), because each Fund generally sells and redeems its shares directly through transactions that are in-kind and/or for cash, subject to

the conditions described below under Creations and Redemptions. The Board has not adopted a policy of monitoring for other frequent trading activity because shares of the Funds are listed for trading on a national securities exchange.

The national securities exchange on which each Fund’s shares are listed is open for trading Monday through Friday and is closed on weekends and the following holidays: New Year’s Day, Martin Luther King, Jr. Day, Presidents’ Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day. Each Fund’s primary listing exchange is NYSE Arca.

Book Entry. Shares of the Funds are held in book-entry form, which means that no stock certificates are issued. The Depository Trust Company (“DTC”) or its nominee is the record owner of all outstanding shares of each Fund and is recognized as the owner of all shares for all purposes.

Investors owning shares of the Funds are beneficial owners as shown on the records of DTC or its participants. DTC serves as the securities depository for shares of the Funds. DTC participants include securities brokers and dealers, banks, trust companies, clearing corporations and other institutions that directly or indirectly maintain a custodial relationship with DTC. As a beneficial owner of shares, you are not entitled to receive physical delivery of stock certificates or to have shares registered in your name, and you are not considered a registered owner of shares. Therefore, to exercise any right as an owner of shares, you must rely upon the procedures of DTC and its participants. These procedures are the same as those that apply to any other securities that you hold in book-entry or “street name” form.

Share Prices. The trading prices of a Fund’s shares in the secondary market generally differ from the Fund’s daily NAV and are affected by market forces such as supply and demand, economic conditions and other factors. Information regarding the intraday value of shares of each Fund, also known as the “indicative optimized portfolio value” (“IOPV”), is disseminated every 15 seconds throughout the trading day by the national securities exchange on which the Fund’s shares are listed or by market data vendors or other information providers. The IOPV is based on the current market value of the securities and/or cash required to be deposited in exchange for a Creation Unit. The IOPV does not necessarily reflect the precise composition of the current portfolio of securities held by a Fund at a particular point in time or the best possible valuation of the current portfolio. Therefore, the IOPV should not be viewed as a “real-time” update of each Fund’s NAV, which is computed only once a day. The IOPV is generally determined by using both current market quotations and/or price quotations obtained from broker-dealers that may trade in the portfolio securities held by the Funds. The quotations of certain Fund holdings may not be updated during U.S. trading hours if such holdings do not trade in the United States. The Funds are not involved in, or responsible for, the calculation or dissemination of the IOPV and make no representation or warranty as to its accuracy.

Determination of Net Asset Value. The NAV for each Fund normally is determined once daily Monday through Friday, generally as of the regularly scheduled close of business of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m., Eastern time) on each day that the NYSE is open for trading, based on prices at the time of closing provided that (a) any Fund assets or liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers (as detailed below) and (b) U.S. fixed income assets may be valued as of the announced closing time for trading in fixed income instruments in a particular market or exchange. The NAV of each Fund is calculated by dividing the value of the net assets of a Fund (i.e., the value of its total assets, which includes the net asset values of the Underlying Fund shares in which a Fund invests, less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets held by the Fund, and its liabilities, are determined pursuant to valuation policies and procedures approved by the Board. The Fund’s assets and liabilities are valued primarily on the basis of market quotations.

Equity investments are valued at market value, which is generally determined using the last reported official closing price or last trading price on the exchange or market on which the security is primarily traded at the time of valuation.

Generally, trading in foreign securities, U.S. government securities, money market instruments and certain fixed-income securities is substantially completed each day at various times prior to the close of business on the NYSE. The values of such securities used in computing the NAV of the Funds are determined as of such times.

When market quotations are not readily available or are believed by BFA to be unreliable, the Fund’s investments are valued at fair value. Fair value determinations are made by BFA in accordance with policies and procedures approved by the Fund’s Board. BFA may conclude that a market quotation is not readily available or is unreliable if a security or other asset or liability does not have a price source due to its lack of liquidity, if a market quotation differs significantly from recent price quotations or otherwise no longer appears to reflect fair value, where the security or other asset or liability is thinly traded, or where there is a significant event subsequent to the most recent market quotation. A “significant event” is an event that, in the judgment of BFA, is likely to cause a material change to the closing market price of the asset or liability held by the Fund. Foreign securities whose values are affected by volatility that occurs in U.S. markets on a trading day after the close of foreign securities markets may be fair valued.

Fair value represents a good faith approximation of the value of an asset or liability. The fair value of an asset or liability held by the Fund is the amount the Fund might reasonably expect to receive from the current sale of that asset or the cost to extinguish that liability in an arm’s-length transaction. Valuing the Fund’s investments using fair value pricing will result in prices that may differ from current market valuations and that may not be the price at which those investments could have been sold during the period in which the particular fair values were used. Use of fair value prices and certain current market valuations could result in a difference between the prices used to calculate the Fund’s NAV and the prices used by the Underlying Index, which, in turn, could result in a difference between the Fund’s performance and the performance of the Underlying Index.

Dividends and Distributions

General Policies. Dividends from net investment income, if any, generally are declared and paid at least monthly by each Fund. Each Fund generally distributes its net capital gains, if any, to shareholders annually. Distributions of net realized securities gains, if any, generally are declared and paid once a year, but the Trust may make distributions on a more frequent basis for each Fund. The Trust reserves the right to declare special distributions if, in its reasonable discretion, such action is necessary or advisable to preserve its status as a regulated investment company (“RIC”) or to avoid imposition of income or excise taxes on undistributed income or realized gains.

Dividends and other distributions on shares of each Fund are distributed on a pro rata basis to beneficial owners of such shares. Dividend payments are made through DTC participants and indirect participants to beneficial owners then of record with proceeds received from a Fund.

Dividend Reinvestment Service. No dividend reinvestment service is provided by the Trust. Broker-dealers may make available the DTC book-entry Dividend Reinvestment Service for use by beneficial owners of a Fund for reinvestment of their dividend distributions. Beneficial owners should contact their broker to determine the availability and costs of the service and the details of participation therein. Brokers may require beneficial owners to adhere to specific procedures and timetables. If this service is available and used, dividend distributions of both income and realized gains will be automatically reinvested in additional whole shares of a Fund purchased in the secondary market.

Taxes. As with any investment, you should consider how your investment in shares of the Funds will be taxed. The tax information in this Prospectus is provided as general information, based on current law. You should consult your own tax professional about the tax consequences of an investment in shares of the Funds.

Unless your investment in Fund shares is made through a tax-exempt entity or tax-deferred retirement account, such as an IRA, you need to be aware of the possible tax consequences when a Fund makes distributions or you sell Fund shares.

Taxes on Distributions. Distributions from a Fund’s net investment income (other than qualified dividend income), including distributions of income from securities lending and distributions out of the Fund’s net short-term capital gains, if any, are taxable to you as ordinary income. Distributions by a Fund of net long-term capital gains in excess of net short-term capital losses (capital gain dividends) are taxable to you as long-term capital gains, generally at a 15% tax rate (0% at certain income levels), regardless of how long you have held a Fund’s shares. Distributions by a Fund that qualify as qualified dividend income are taxable to you at long-term capital gain rates for taxable years beginning on or before December 31, 2012. The 15% and 0% tax rates expire for taxable years beginning after December 31, 2012. Maximum long-term capital gain income tax rates are scheduled to rise to 20% in 2013. Beginning in 2013, a 3.8% U.S. federal Medicare contribution tax will be imposed on “net investment income,” including interest, dividends, and capital gains, of U.S. individuals with income exceeding $200,000 (or $250,000 if married and filing jointly), and of estates and trusts.

Dividends will be qualified dividend income to you if they are attributable to qualified dividend income received by a Fund. Generally, qualified dividend income includes dividend income from taxable U.S. corporations, provided that a Fund satisfies certain holding period requirements in respect of the stock of such corporations and has not hedged its position in the stock in certain ways. Substitute dividends received by a Fund with respect to dividends paid on securities lent out will not be qualified dividend income. For this purpose, a qualified non-U.S. corporation means any non-U.S. corporation that is eligible for benefits under a comprehensive income tax treaty with the United States, which includes an exchange of information program or if the stock with respect to which the dividend was paid is readily tradable on an established United States securities market. The term excludes a corporation that is a passive foreign investment company.

Dividends received by a Fund from a REIT or another RIC generally are qualified dividend income only to the extent the dividend distributions are made out of qualified dividend income received by such REIT or RIC. It is expected that dividends received by a Fund from a REIT and distributed to a shareholder generally will be taxable to the shareholder as ordinary income.

For a dividend to be treated as qualified dividend income, the dividend must be received with respect to a share of stock held without being hedged by an Underlying Fund, and with respect to a share of an Underlying Fund held by a Fund without being hedged by a Fund, or to any share of a Fund held without being hedged by you, for 61 days during the 121-day period beginning at the date which is 60 days before the date on which such share becomes ex-dividend with respect to such dividend or, in the case of certain preferred stock, 91 days during the 181-day period beginning 90 days before such date.

If your Fund shares are loaned out pursuant to a securities lending arrangement, you may lose the ability to use foreign tax credits passed through by the Fund or to treat Fund dividends paid while the shares are held by the borrower as qualified dividend income.

In general, your distributions are subject to U.S. federal income tax for the year when they are paid. Certain distributions paid in January, however, may be treated as paid on December 31 of the prior year.

Short-term capital gain earned by an Underlying Fund will be ordinary income when distributed to a Fund and will not be offset by the Fund’s capital losses.

If a Fund’s distributions exceed current and accumulated earnings and profits, all or a portion of the distributions made in the taxable year may be recharacterized as a return of capital to shareholders. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and result in a higher capital gain or lower capital loss when those shares on which the distribution was received are sold. Once a shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain, if the shareholder holds shares of the Fund as capital assets.

If you are neither a resident nor a citizen of the United States or if you are a non-U.S. entity, a Fund’s ordinary income dividends (which include distributions of net short-term capital gains) will generally be subject to a 30% U.S. withholding tax, unless a lower treaty rate applies,

provided that withholding tax will generally not apply to any gain or income realized by a non-U.S. shareholder in respect of any distributions of long-term capital gains or upon the sale or other disposition of shares of a Fund.

A 30% withholding tax will be imposed on dividends paid after December 31, 2013, and redemption proceeds paid after December 31, 2014, to (i) foreign financial institutions including non-U.S. investment funds unless they agree to collect and disclose to the IRS information regarding their direct and indirect U.S. account holders and (ii) certain other foreign entities, unless they certify certain information regarding their direct and indirect U.S. owners. To avoid withholding, foreign financial institutions will need to enter into agreements with the IRS that state that they will provide the IRS information, including the name, address and taxpayer identification number of direct and indirect U.S. account holders, comply with due diligence procedures with respect to the identification of U.S. accounts, report to the IRS certain information with respect to U.S. accounts maintained, agree to withhold tax on certain payments made to non-compliant foreign financial institutions or to account holders who fail to provide the required information, and determine certain other information as to their account holders. Other foreign entities will need to provide the name, address, and taxpayer identification number of each substantial U.S. owner or certifications of no substantial U.S. ownership unless certain exceptions apply.

Dividends, interest and capital gains received by the Underlying Funds with respect to non-U.S. securities may give rise to withholding and other taxes imposed by non-U.S. countries which may reduce returns. Tax conventions between certain countries and the United States may reduce or eliminate such taxes. If, as is expected, more than 50% of the total assets of the Fund at the close of a year consists of shares of the underlying funds, the Fund may “pass through” to you certain non-U.S. income taxes (including withholding taxes) paid by the Fund or passed through to the Fund from Underlying Funds.

As the Funds invest in only a limited number of positions, the Funds may be required to defer for tax purposes significant amounts of realized losses on the sale of shares in Underlying Funds indefinitely.

If you are a resident or a citizen of the United States, by law, back-up withholding will apply to your distributions and proceeds if you have not provided a taxpayer identification number or social security number and made other required certifications.

Taxes When Shares are Sold. Currently, any capital gain or loss realized upon a sale of Fund shares is generally treated as a long-term gain or loss if the shares have been held for more than one year. Any capital gain or loss realized upon a sale of Fund shares held for one year or less is generally treated as short-term gain or loss, except that any capital loss on the sale of shares held for six months or less is treated as long-term capital loss to the extent that capital gain dividends were paid with respect to such shares. Beginning in 2013, any such capital gains, including from sales of Fund shares or from capital gain dividends, will be included in “net investment income” for purposes of the 3.8% U.S. federal Medicare contribution tax mentioned above.

The foregoing discussion summarizes some of the consequences under current U.S. federal tax law of an investment in a Fund. It is not a substitute for personal tax advice. You may also be subject to state and local taxation on Fund distributions and sales of shares. Consult your personal tax adviser about the potential tax consequences of an investment in shares of a Fund under all applicable tax laws.

Creations and Redemptions. Prior to trading in the secondary market, shares of each Fund are “created” at NAV by market makers, large investors and institutions only in block-size Creation Units of 50,000 shares or multiples thereof. Each “creator” or “Authorized Participant” enters into an authorized participant agreement with the Fund’s distributor, SEI Investments Distribution Co. (the “Distributor”). Only an Authorized Participant may create or redeem Creation Units directly with a Fund. A creation transaction, which is subject to acceptance by the transfer agent, generally takes place when an Authorized Participant deposits into a Fund a designated portfolio of securities approximating the holdings of the Fund and a specified amount of cash in exchange for a specified number of Creation Units. To the extent practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund.

Similarly, shares can be redeemed only in Creation Units, generally for a designated portfolio of securities and a specified amount of cash held by the Fund (“Fund Securities”). Except when aggregated in Creation Units, shares are not redeemable by the Funds. The prices at which creations and redemptions occur are based on the next calculation of NAV after an order is received in a form described in the authorized participant agreement.

Each Fund intends to comply with the U.S. federal securities laws in accepting securities for deposits and satisfying redemptions with redemption securities by, among other means, assuring that any securities accepted for deposits and any securities used to satisfy redemption requests will be sold in transactions that would be exempt from registration under the Securities Act of 1933, as amended (the “1933 Act”). Further, an Authorized Participant that is not a “qualified institutional buyer,” as such term is defined under Rule 144A of the 1933 Act, will not be able to receive Fund Securities that are restricted securities eligible for resale under Rule 144A.

Creations and redemptions must be made through a firm that is either a member of the Continuous Net Settlement System of the National Securities Clearing Corporation or a DTC participant and has executed an agreement with the Distributor with respect to creations and redemptions of Creation Unit aggregations. Information about the procedures regarding creation and redemption of Creation Units (including the cut-off times for receipt of creation and redemption orders) is included in the Funds’ SAI.

Because new shares may be created and issued on an ongoing basis, at any point during the life of a Fund a “distribution,” as such term is used in the 1933 Act, may be occurring. Broker-dealers and other persons are cautioned that some activities on their part may, depending on the circumstances, result in their being deemed participants in a distribution in a manner that could render them statutory underwriters and subject to the prospectus delivery and liability provisions of the 1933 Act. Any determination of whether one is an underwriter must take into account all the relevant facts and circumstances of each particular case.

Broker-dealers should also note that dealers who are not “underwriters” but are participating in a distribution (as contrasted to ordinary secondary transactions), and thus dealing with shares that are part of an “unsold allotment” within the meaning of Section 4(3)(C) of the

1933 Act, would be unable to take advantage of the prospectus delivery exemption provided by Section 4(3) of the 1933 Act. For delivery of prospectuses to exchange members, the prospectus delivery mechanism of Rule 153 under the 1933 Act is available only with respect to transactions on a national securities exchange.

Costs Associated with Creations and Redemptions. Authorized Participants are charged standard creation and redemption transaction fees to offset transfer and other transaction costs associated with the issuance and redemption of Creation Units. The standard creation and redemption transaction fees are set forth in the table below. The standard creation transaction fee is charged to the Authorized Participant on the day such Authorized Participant creates a Creation Unit, and is the same regardless of the number of Creation Units purchased by the Authorized Participant on the applicable business day. Similarly, the standard redemption transaction fee is charged to the Authorized Participant on the day such Authorized Participant redeems a Creation Unit, and is the same regardless of the number of Creation Units redeemed by the Authorized Participant on the applicable business day. Creations and redemptions for cash (when cash creations and redemptions (in whole or in part) are available or specified) are also subject to an additional charge (up to the maximum amounts shown in the table below). This charge is intended to compensate for brokerage, tax, foreign exchange, execution, market impact and other costs and expenses related to cash transactions. Investors who use the services of a broker or other financial intermediary may pay fees for such services.

The following table shows, as of September 30, 2011, the approximate value of one Creation Unit, standard fees and maximum additional charges for creations and redemptions (as described above):

Householding. Householding is an option available to certain Fund investors. Householding is a method of delivery, based on the preference of the individual investor, in which a single copy of certain shareholder documents can be delivered to investors who share the same address, even if their accounts are registered under different names. Please contact your broker-dealer if you are interested in enrolling in householding and receiving a single copy of prospectuses and other shareholder documents, or if you are currently enrolled in householding and wish to change your householding status.

Distribution

The Distributor distributes Creation Units for each Fund on an agency basis. The Distributor does not maintain a secondary market in shares of the Funds. The Distributor has no role in determining the policies of any Fund or the securities that are purchased or sold by any Fund. The Distributor’s principal address is One Freedom Valley Drive, Oaks, PA 19456.

In addition, BFA or its Affiliates make payments to broker-dealers, banks or other financial intermediaries (together, “intermediaries”) related to marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems, or their making shares of the Funds and certain other iShares funds available to their customers. Such payments, which may be significant to the intermediary, are not made by the Funds. Rather, such payments are made by BFA or its Affiliates from their own resources, which come directly or indirectly in part from fees paid by the iShares funds complex. Payments of this type are sometimes referred to as revenue-sharing payments. A financial intermediary may make decisions about which investment options it recommends or

makes available, or the level of services provided, to its customers based on the revenue-sharing payments it is eligible to receive. Therefore, such payments to an intermediary create conflicts of interest between the intermediary and its customers and may cause the intermediary to recommend the Funds or other iShares funds over another investment. More information regarding these payments is contained in the Funds’ SAI. Please contact your salesperson or other investment professional for more information regarding any such payments his or her firm may receive from BFA or its Affiliates.

Financial Highlights

The financial highlights table is intended to help investors understand each Fund’s financial performance since inception (other than the iShares S&P Target Date 2045 Index Fund and the iShares S&P Target Date 2050 Index Fund because these Funds commenced operations after the Funds’ fiscal year end, July 31, 2011). Certain information reflects financial results for a single share of each Fund. The total returns in the table represent the rate that an investor would have earned (or lost) on an investment in each Fund, assuming reinvestment of all dividends and distributions. This information has been audited by PricewaterhouseCoopers LLP, whose report is included, along with the Fund’s financial statements, in the Fund’s Annual Report (available upon request).

Supplemental Information

I. Premium/Discount Information

Each table that follows presents information about the differences between the daily market price on secondary markets for shares of a Fund (other than the iShares S&P Target Date 2045 Index Fund and the iShares S&P Target Date 2050 Index Fund because these funds do not have a full calendar quarter of premiums and discounts to report). and the Fund’s NAV. NAV is the price at which each Fund issues and redeems shares. It is calculated in accordance with the standard formula for valuing mutual fund shares. The price used to calculate market returns (“Market Price”) of each Fund generally is determined using the midpoint between the highest bid and the lowest offer on the primary securities exchange on which shares of such Fund are listed for trading, as of the time that each Fund’s NAV is calculated. Each Fund’s Market Price may be at, above or below its NAV. The NAV of each Fund will fluctuate with changes in the value of its portfolio holdings. The Market Price of each Fund will fluctuate in accordance with changes in its NAV, as well as market supply and demand.

Premiums or discounts are the differences (expressed as a percentage) between the NAV and Market Price of a Fund on a given day, generally at the time the NAV is calculated. A premium is the amount that a Fund is trading above the reported NAV, expressed as a percentage of the NAV. A discount is the amount that a Fund is trading below the reported NAV, expressed as a percentage of the NAV.

The following information shows the frequency of distributions of premiums and discounts for each Fund for each full calendar quarter of 2010 through September 30, 2011.

Each line in the table shows the number of trading days in which each Fund traded within the premium/discount range indicated. The number of trading days in each premium/discount range is also shown as a percentage of the total number of trading days in a period covered by the table. All data presented here represents past performance, which cannot be used to predict future results.

II. Total Return Information

The tables that follow present information about the total returns of each Fund (other than the iShares S&P Target Date 2045 Index Fund and the iShares S&P Target Date 2050 Index Fund because these Funds commenced operations after the Funds’ fiscal year end, July 31, 2011) and the Underlying Index as of the fiscal year ended July 31, 2011.

“Average Annual Total Returns” represent the average annual change in value of an investment over the periods indicated. “Cumulative Total Returns” represent the total change in value of an investment over the periods indicated.

Each Fund’s NAV is the value of one share of such Fund as calculated in accordance with the standard formula for valuing mutual fund shares. The NAV return is based on the NAV of each Fund and the market return is based on the Market Price of each Fund. Market Price is determined by using the midpoint between the highest bid and the lowest offer on the primary stock exchange on which shares of each Fund are listed for trading, as of the time that such Fund’s NAV is calculated. Since shares of each Fund did not trade in the secondary market until after each Fund’s inception, for the period from inception to the first day of secondary market trading in shares of each Fund, the NAV of each Fund is used as a proxy for the Market Price to calculate market returns. Market and NAV returns assume that dividends and capital gain distributions have been reinvested in each Fund at Market Price and NAV, respectively.

An index is a statistical composite that tracks a specified financial market or sector. Unlike each Fund, the Underlying Index does not actually hold a portfolio of securities and therefore does not incur the expenses incurred by each Fund. These expenses negatively impact the performance of each Fund. Also, market returns do not include brokerage commissions that may be payable on secondary market transactions. If brokerage commissions were included, market returns would be lower. The returns shown in the following tables do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption or sale of Fund shares. The investment return and principal value of shares of each Fund will vary with changes in market conditions. Shares of each Fund may be worth more or less than their original cost when they are redeemed or sold in the market. Each Fund’s past performance is no guarantee of future results.

iShares S&P Conservative Allocation Fund

iShares S&P Conservative Allocation Fund

Ticker: AOK Stock Exchange: NYSE Arca

Investment Objective

The iShares S&P Conservative Allocation Fund (the “Fund”) seeks investment results that correspond generally to the price and yield performance, before fees and expenses, of the S&P Target Risk Conservative Index (the “Underlying Index”).

Fees and Expenses

The following table describes the fees and expenses that you will incur if you own shares of the Fund. The investment advisory agreement between iShares Trust (the “Trust”) and BlackRock Fund Advisors (“BFA”) (the “Investment Advisory Agreement”) provides that BFA will pay all operating expenses of the Fund, except interest expenses, taxes, brokerage expenses, future distribution fees or expenses, and extraordinary expenses. “Acquired Fund Fees and Expenses” reflect the Fund’s pro rata share of the fees and expenses incurred by investing in other investment companies. The impact of Acquired Fund Fees and Expenses is included in the total returns of the Fund. Acquired Fund Fees and Expenses are not used to calculate the Fund’s net asset value per share (“NAV”) and are not included in the calculation of the ratio of expenses to average net assets shown in the Financial Highlights section of the Fund’s prospectus (the “Prospectus”). BFA has contractually agreed to waive a portion of the advisory fee it is entitled to receive from the Fund due to its investments in other iShares funds, in an amount equal to 0.14%, through June 30, 2013. The contractual waiver may be terminated prior to June 30, 2013 only upon written agreement of the Trust and BFA.

You will also incur usual and customary brokerage commissions when buying or selling shares of the Fund, which are not reflected in the example that follows:

Example. This Example is intended to help you compare the cost of owning shares of the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

1 Year
3 Years
5 Years
10 Years
$31 $118 $224 $533

Portfolio Turnover. The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 7% of the average value of its portfolio.

Principal Investment Strategies

The Fund is a fund of funds and seeks its investment objective by investing primarily in the securities of other iShares funds (each, an “Underlying Fund” and collectively, the “Underlying Funds”) that themselves seek investment results corresponding to their own underlying index. The Underlying Funds invest primarily in distinct asset classes, such as large-capitalization U.S. equity, mid-capitalization U.S. equity, emerging market securities, the aggregate bond market or the U.S. treasury bond market; each such asset class has its own risk profile.

The Underlying Index measures the performance of S&P’s proprietary allocation model, which is intended to represent a “conservative” target risk allocation strategy as defined by S&P. S&P’s estimation of a conservative target risk allocation may differ from your own.

The Fund is designed for investors seeking current income, capital preservation and avoidance of excessive volatility of returns. In 2011, for the Underlying Index, S&P defined that as a 18% probability of losing at least 21% of its value. It is possible that an investor in the Fund could lose a significantly larger percentage of their investment. As of September 30, 2011, the Fund invested approximately 18.35% of its assets in Underlying Funds that invest primarily in equity securities, 81.44% of its assets in Underlying Funds that invest primarily in bonds and the remainder of its assets in Underlying Funds that invest primarily in money market instruments.

As of September 30, 2011, the Fund invested in the iShares S&P 500 Index Fund, iShares S&P MidCap 400 Index Fund, iShares S&P SmallCap 600 Index Fund, iShares MSCI EAFE Index Fund, iShares MSCI Emerging Markets Index Fund, iShares Barclays Aggregate Bond Fund, iShares Barclays Short Treasury Bond Fund, iShares Barclays TIPS Bond Fund, iShares iBoxx $ High Yield

Table Of Contents



Corporate Bond Fund and BlackRock Cash Funds. BFA may add, eliminate or replace all Underlying Funds at any time.

BFA uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to “beat” the index it tracks and does not seek temporary defensive positions when markets decline or appear overvalued.

Indexing may eliminate the chance that the Fund will substantially outperform the Underlying Index but also may reduce some of the risks of active management, such as poor security selection. Indexing seeks to achieve lower costs and better after-tax performance by keeping portfolio turnover low in comparison to actively managed investment companies.

BFA uses a representative sampling indexing strategy to manage the Funds. “Representative sampling” is an indexing strategy that involves investing in a representative sample of securities that collectively has an investment profile similar to the Underlying Index. The securities selected are expected to have, in the aggregate, investment characteristics (based on factors such as market capitalization and industry weightings), fundamental characteristics (such as return variability and yield) and liquidity measures similar to those of the Underlying Index. The Fund may or may not hold all of the securities in the Underlying Index.

The Fund generally invests at least 90% of its assets in securities of the Underlying Index. The Fund may invest the remainder of its assets in securities not included in the Underlying Index, but which BFA believes will help the Fund track its Underlying Index and in other investments including futures contracts, options on futures contracts and options, as well as cash and cash equivalents, including shares of money market funds affiliated with BFA or its affiliates, to the extent permitted under the Investment Company Act of 1940, as amended (the “1940 Act”).

The Fund may lend securities representing up to one-third of the value of the Fund’s total assets (including the value of the collateral received).

The Underlying Index is sponsored by an organization (the “Index Provider”) that is independent of the Fund and BFA. The Index Provider determines the composition and relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index. The Fund’s Index Provider is Standard & Poor’s Financial Services LLC (a subsidiary of The McGraw-Hill Companies) (“S&P”).

Industry Concentration Policy. The Fund will concentrate its investments (i.e., hold 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. For purposes of this limitation, securities of the U.S. government (including its agencies and instrumentalities) and repurchase agreements collateralized by U.S. government securities are not considered to be issued by members of any industry.

Summary of Principal Risks

As with any investment, you could lose all or part of your investment in the Fund, and the Fund’s performance could trail that of other investments. The Fund is subject to the principal risks noted below (either directly or through its investments in the Underlying Funds), any of which may adversely affect the Fund’s NAV, trading price, yield, total return and ability to meet its investment objective.

Asset Class Risk. Securities in the Underlying Index or in the Fund’s portfolio may underperform in comparison to the general securities markets or other asset classes.

Credit Risk. The risk that debt issuers and other counterparties may not honor their obligations or may have their debt downgraded by ratings agencies.

Emerging Markets Risk. Investments in emerging markets may be subject to a greater risk of loss than investments in more developed markets. Emerging markets may be more likely to experience inflation risk, political turmoil and rapid changes in economic conditions than more developed markets. Emerging markets often have less uniformity in accounting and reporting requirements, unreliable securities valuation and greater risk associated with custody of securities.

Equity Securities Risk. Equity securities are subject to changes in value and their values may be more volatile than other asset classes.

Financial Sector Risk. Performance of companies in the financial sector may be adversely impacted by many factors, including, among others, government regulations, economic conditions, credit rating downgrades, changes in interest rates, and decreased liquidity in credit markets. This sector has experienced significant losses in the recent past, and the impact of more stringent capital requirements and of recent or future regulation on any individual financial company or on the sector as a whole cannot be predicted.

Industrials Sector Risk. The industrials sector is affected by changes in the supply and demand for products and services, product obsolescence, claims for environmental damage or product liability and general economic conditions, among other factors.

Information Technology Sector Risk. Information technology companies face intense competition and potentially rapid product obsolescence. They are also heavily dependent on intellectual property rights and may be adversely affected by loss or impairment of those rights.

Interest Rate Risk. An increase in interest rates may cause the value of fixed-income securities held by the Fund or an Underlying Fund to decline.

Issuer Risk. Fund performance depends on the performance of individual securities to which the Fund or an Underlying Fund has exposure. Changes to the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA’s investment management strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares, losses from trading in secondary markets, periods of high volatility and disruption in the creation/redemption process of the Fund. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV.

Mid-Capitalization Companies Risk. The Fund or an Underlying Fund invests in the securities of mid-capitalization companies. Compared to large-capitalization companies, mid-capitalization companies may be less stable and more susceptible to adverse developments and their securities may be more volatile and less liquid.

Model Risk. Neither the Fund nor BFA can offer assurances that the Underlying Index’s allocation model will maximize returns or minimize risk, or be appropriate for every investor seeking a particular risk profile.

Mortgage-Backed Securities Risk. The Fund invests in mortgage-backed securities (“MBS”), some of which may not be backed by the full faith and credit of the U.S. government. MBS are subject to prepayment risk and extension risk. Because of these risks, MBS react differently to changes in interest rates than other bonds. Small movements in interest rates (both increases and decreases) may quickly and significantly reduce the value of certain MBS.

Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers are subject to the risks associated with investing in those non-U.S. markets, such as heightened risks of inflation or nationalization. The Fund may lose money due to political, economic and geographic events affecting a non-U.S. issuer or market.

Passive Investment Risk. The Fund is not actively managed and BFA does not attempt to take defensive positions under any market conditions, including declining markets.

Reinvestment Risk. The Fund or an Underlying Fund invests in short-term fixed-income instruments and may be adversely affected if interest rates fall because it may invest in lower yielding bonds as bonds in the portfolio mature.

Risk of Investing in Russia. Investing in Russian securities involves significant risks, including legal, regulatory and economic risks that are specific to Russia. In addition, investing in Russian securities involves risks associated with the settlement of portfolio transactions and loss of the Fund’s ownership rights in its portfolio securities, as a result of the system of share registration and custody in Russia.

Securities Lending Risk. The Fund or an Underlying Fund may engage in securities lending. Securities lending involves the risk that the Fund or an Underlying Fund may lose money because the borrower of the Fund’s loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Small-Capitalization Companies Risk. The Fund or an Underlying Fund invests in the securities of small-capitalization companies. Compared to mid- and large-capitalization companies, small-capitalization companies may be less stable and more susceptible to adverse developments and their securities may be more volatile and less liquid.

Subsidiary Risk. By investing in the Subsidiary, the Fund is indirectly exposed to the risks associated with the Subsidiary’s investments. The commodity-related instruments that may be held by the Subsidiary are generally similar to those that are permitted to be held by the Fund and are subject to the same risks that would apply to similar investments if held directly by the Fund. There can be no assurance that the investment objective of the Subsidiary will be achieved. The Subsidiary is not registered under the 1940 Act, and, unless otherwise noted in this prospectus, is not subject to all the investor protections of the 1940 Act. Changes in the laws of the United States and/or the Cayman Islands could result in the inability of the Fund and/or the Subsidiary to operate as described in this prospectus and the Statement of Additional Information (“SAI”) and could adversely affect the Fund.

Tracking Error Risk. The performance of the Fund may diverge from that of the Underlying Index. Because the Fund employs a representative sampling strategy, the Fund may experience tracking error to a greater extent than a fund that seeks to replicate an index.

Treasury Obligations Risk. Treasury obligations may differ in their interest rates, maturities, times of issuance and other characteristics. Similar to other issuers, changes to the financial condition or credit rating of a government may cause the value of the Fund’s Treasury obligations to decline.

Valuation Risk. The value of the securities in the Fund’s portfolio may change on days when shareholders will not be able to purchase or sell the Fund’s shares.

Performance Information

The bar chart and table that follow show how the Fund has performed on a calendar year basis and provide an indication of the risks of investing in the Fund. Both assume that all dividends and distributions have been reinvested in the Fund. Past performance (before and after taxes) does not necessarily indicate how the Fund will perform in the future. Supplemental information about the Fund’s performance is shown under the heading Total Return Information in the Supplemental Information section of the Prospectus.

Year by Year Returns1 (Years Ended December 31)

Actual after-tax returns depend on an investor’s tax situation and may differ from those shown, and after-tax returns shown are not relevant to tax-exempt investors or investors who hold shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts (“IRAs”). Fund returns after taxes on distributions and sale of Fund shares are calculated assuming that an investor has sufficient capital gains of the same character from other investments to offset any capital losses from the sale of Fund shares. As a result, Fund returns after taxes on distributions and sale of Fund shares may exceed Fund returns before taxes and/or returns after taxes on distributions.

Management

Investment Adviser. BlackRock Fund Advisors.

Portfolio Managers. Rene Casis, Diane Hsiung and Greg Savage (the “Portfolio Managers”) are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager supervises a portfolio management team. Mr. Casis, Ms. Hsiung and Mr. Savage have been Portfolio Managers of the Fund since 2010, 2008 and 2008, respectively.

Purchase and Sale of Fund Shares

The Fund is an exchange-traded fund (commonly referred to as an “ETF”). Individual Fund shares may only be purchased and sold on a national securities exchange through a broker-dealer. The price of Fund shares is based on market price, and because ETF shares trade at market prices rather than NAV, shares may trade at a price greater than NAV (a premium) or less than NAV (a discount). The Fund will only issue or redeem shares that have been aggregated into blocks of 50,000 shares or multiples thereof (“Creation Units”) to authorized participants who have entered into agreements with the Fund’s distributor. The Fund generally will issue or redeem Creation Units in return for a designated portfolio of securities (and an amount of cash) that the Fund specifies each day.

Tax Information

The Fund intends to make distributions that may be taxable to you as ordinary income or capital gains, unless you are investing through a tax-deferred arrangement such as a 401(k) plan or an IRA.

Payments to Broker-Dealers and other Financial Intermediaries

If you purchase shares of the Fund through a broker-dealer or other financial intermediary (such as a bank), BFA or other related companies may pay the intermediary for marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems or other services related to the sale or promotion of the Funds. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Funds over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.

iShares S&P Moderate Allocation Fund

iShares S&P Moderate Allocation Fund

Ticker: AOM Stock Exchange: NYSE Arca

Investment Objective

The iShares S&P Moderate Allocation Fund (the “Fund”) seeks investment results that correspond generally to the price and yield performance, before fees and expenses, of the S&P Target Risk Moderate Index (the “Underlying Index”).

Fees and Expenses

The following table describes the fees and expenses that you will incur if you own shares of the Fund. The investment advisory agreement between iShares Trust (the “Trust”) and BlackRock Fund Advisors (“BFA”) (the “Investment Advisory Agreement”) provides that BFA will pay all operating expenses of the Fund, except interest expenses, taxes, brokerage expenses, future distribution fees or expenses, and extraordinary expenses. “Acquired Fund Fees and Expenses” reflect the Fund’s pro rata share of the fees and expenses incurred by investing in other investment companies. The impact of Acquired Fund Fees and Expenses is included in the total returns of the Fund. Acquired Fund Fees and Expenses are not used to calculate the Fund’s net asset value per share (“NAV”) and are not included in the calculation of the ratio of expenses to average net assets shown in the Financial Highlights section of the Fund’s prospectus (the “Prospectus”). BFA has contractually agreed to waive a portion of the advisory fee it is entitled to receive from the Fund due to its investments in other iShares funds, in an amount equal to 0.14%, through June 30, 2013. The contractual waiver may be terminated prior to June 30, 2013 only upon written agreement of the Trust and BFA.

You will also incur usual and customary brokerage commissions when buying or selling shares of the Fund, which are not reflected in the example that follows:

Annual Fund Operating Expenses

percentage of the value of your investments)

Example. This Example is intended to help you compare the cost of owning shares of the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

1 Year
3 Years
5 Years
10 Years
$32 $122 $229 $545

Portfolio Turnover. The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 9% of the average value of its portfolio.

Principal Investment Strategies

The Fund is a fund of funds and seeks its investment objective by investing primarily in the securities of other iShares funds (each, an “Underlying Fund” and collectively, the “Underlying Funds”) that themselves seek investment results corresponding to their own underlying index. The Underlying Funds invest primarily in distinct asset classes, such as large-capitalization U.S. equity, mid-capitalization U.S. equity, emerging market securities, the aggregate bond market or the U.S. treasury bond market; each such asset class has its own risk profile.

The Underlying Index measures the performance of S&P’s proprietary allocation model, which is intended to represent a “moderate” target risk allocation strategy as defined by S&P. S&P’s estimation of a moderate target risk allocation may differ from your own.

The Fund is designed for investors seeking current income, some capital preservation and an opportunity for moderate to low capital appreciation. In 2011, for the Underlying Index, S&P defined that as a 22% probability of losing at least 25% of its value. It is possible that an investor in the Fund could lose a significantly larger percentage of their investment. As of September 30, 2011, the Fund invested approximately 32.57% of its assets in Underlying Funds that invest primarily in equity securities, 67.28% of its assets in Underlying Funds that invest primarily in bonds and the remainder of its assets in Underlying Funds that invest primarily in money market instruments.

As of September 30, 2011, the Fund invested in the iShares S&P 500 Index Fund, iShares S&P MidCap 400 Index Fund, iShares S&P SmallCap 600 Index Fund, iShares MSCI EAFE Index Fund, iShares MSCI Emerging Markets Index Fund, iShares Barclays Aggregate Bond Fund, iShares Barclays Short Treasury Bond Fund, iShares Barclays TIPS Bond Fund, iShares iBoxx $ High Yield

Table Of Contents



Corporate Bond Fund and BlackRock Cash Funds. BFA may add, eliminate or replace all Underlying Funds at any time.

BFA uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to “beat” the index it tracks and does not seek temporary defensive positions when markets decline or appear overvalued.

Indexing may eliminate the chance that the Fund will substantially outperform the Underlying Index but also may reduce some of the risks of active management, such as poor security selection. Indexing seeks to achieve lower costs and better after-tax performance by keeping portfolio turnover low in comparison to actively managed investment companies.

BFA uses a representative sampling indexing strategy to manage the Funds. “Representative sampling” is an indexing strategy that involves investing in a representative sample of securities that collectively has an investment profile similar to the Underlying Index. The securities selected are expected to have, in the aggregate, investment characteristics (based on factors such as market capitalization and industry weightings), fundamental characteristics (such as return variability and yield) and liquidity measures similar to those of the Underlying Index. The Fund may or may not hold all of the securities in the Underlying Index.

The Fund generally invests at least 90% of its assets in securities of the Underlying Index. The Fund may invest the remainder of its assets in securities not included in the Underlying Index, but which BFA believes will help the Fund track its Underlying Index and in other investments including futures contracts, options on futures contracts and options, as well as cash and cash equivalents, including shares of money market funds affiliated with BFA or its affiliates, to the extent permitted under the Investment Company Act of 1940, as amended (the “1940 Act”).

The Fund may lend securities representing up to one-third of the value of the Fund’s total assets (including the value of the collateral received).

The Underlying Index is sponsored by an organization (the “Index Provider”) that is independent of the Fund and BFA. The Index Provider determines the composition and relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index. The Fund’s Index Provider is Standard & Poor’s Financial Services LLC (a subsidiary of The McGraw-Hill Companies) (“S&P”).

Industry Concentration Policy. The Fund will concentrate its investments (i.e., hold 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. For purposes of this limitation, securities of the U.S. government (including its agencies and instrumentalities) and repurchase agreements collateralized by U.S. government securities are not considered to be issued by members of any industry.

Summary of Principal Risks

As with any investment, you could lose all or part of your investment in the Fund, and the Fund’s performance could trail that of other investments. The Fund is subject to the principal risks noted below (either directly or through its investments in the Underlying Funds), any of which may adversely affect the Fund’s NAV, trading price, yield, total return and ability to meet its investment objective.

Asset Class Risk. Securities in the Underlying Index or in the Fund’s portfolio may underperform in comparison to the general securities markets or other asset classes.

Credit Risk. The risk that debt issuers and other counterparties may not honor their obligations or may have their debt downgraded by ratings agencies.

Emerging Markets Risk. Investments in emerging markets may be subject to a greater risk of loss than investments in more developed markets. Emerging markets may be more likely to experience inflation risk, political turmoil and rapid changes in economic conditions than more developed markets. Emerging markets often have less uniformity in accounting and reporting requirements, unreliable securities valuation and greater risk associated with custody of securities.

Equity Securities Risk. Equity securities are subject to changes in value and their values may be more volatile than other asset classes.

Financial Sector Risk. Performance of companies in the financial sector may be adversely impacted by many factors, including, among others, government regulations, economic conditions, credit rating downgrades, changes in interest rates, and decreased liquidity in credit markets. This sector has experienced significant losses in the recent past, and the impact of more stringent capital requirements and of recent or future regulation on any individual financial company or on the sector as a whole cannot be predicted.

Interest Rate Risk. An increase in interest rates may cause the value of fixed-income securities held by the Fund or an Underlying Fund to decline.

Issuer Risk. Fund performance depends on the performance of individual securities to which the Fund or an Underlying Fund has exposure. Changes to the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA’s investment management strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares, losses from trading in secondary markets, periods of high volatility and disruption in the creation/redemption process of the Fund. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV.

Mid-Capitalization Companies Risk. The Fund or an Underlying Fund invests in the securities of mid-capitalization companies.

S-6   


Table Of Contents



Compared to large-capitalization companies, mid-capitalization companies may be less stable and more susceptible to adverse developments and their securities may be more volatile and less liquid.

Model Risk. Neither the Fund nor BFA can offer assurances that the Underlying Index’s allocation model will maximize returns or minimize risk, or be appropriate for every investor seeking a particular risk profile.

Mortgage-Backed Securities Risk. The Fund invests in mortgage-backed securities (“MBS”), some of which may not be backed by the full faith and credit of the U.S. government. MBS are subject to prepayment risk and extension risk. Because of these risks, MBS react differently to changes in interest rates than other bonds. Small movements in interest rates (both increases and decreases) may quickly and significantly reduce the value of certain MBS.

Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers are subject to the risks associated with investing in those non-U.S. markets, such as heightened risks of inflation or nationalization. The Fund may lose money due to political, economic and geographic events affecting a non-U.S. issuer or market.

Passive Investment Risk. The Fund is not actively managed and BFA does not attempt to take defensive positions under any market conditions, including declining markets.

Reinvestment Risk. The Fund or an Underlying Fund invests in short-term fixed-income instruments and may be adversely affected if interest rates fall because it may invest in lower yielding bonds as bonds in the portfolio mature.

Risk of Investing in Russia. Investing in Russian securities involves significant risks, including legal, regulatory and economic risks that are specific to Russia. In addition, investing in Russian securities involves risks associated with the settlement of portfolio transactions and loss of the Fund’s ownership rights in its portfolio securities, as a result of the system of share registration and custody in Russia.

Securities Lending Risk. The Fund or an Underlying Fund may engage in securities lending. Securities lending involves the risk that the Fund or an Underlying Fund may lose money because the borrower of the Fund’s loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Small-Capitalization Companies Risk. The Fund or an Underlying Fund invests in the securities of small-capitalization companies. Compared to mid- and large-capitalization companies, small-capitalization companies may be less stable and more susceptible to adverse developments and their securities may be more volatile and less liquid.

Subsidiary Risk. By investing in the Subsidiary, the Fund is indirectly exposed to the risks associated with the Subsidiary’s investments. The commodity-related instruments that may be held by the Subsidiary are generally similar to those that are permitted to be held by the Fund and are subject to the same risks that would apply to similar investments if held directly by the Fund. There can be no assurance that the investment objective of the Subsidiary will be achieved. The Subsidiary is not registered under the 1940 Act, and, unless otherwise noted in this prospectus, is not subject to all the investor protections of the 1940 Act. Changes in the laws of the United States and/or the Cayman Islands could result in the inability of the Fund and/or the Subsidiary to operate as described in this prospectus and the Statement of Additional Information (“SAI”) and could adversely affect the Fund.

Tracking Error Risk. The performance of the Fund may diverge from that of the Underlying Index. Because the Fund employs a representative sampling strategy, the Fund may experience tracking error to a greater extent than a fund that seeks to replicate an index.

Treasury Obligations Risk. Treasury obligations may differ in their interest rates, maturities, times of issuance and other characteristics. Similar to other issuers, changes to the financial condition or credit rating of a government may cause the value of the Fund’s Treasury obligations to decline.

Valuation Risk. The value of the securities in the Fund’s portfolio may change on days when shareholders will not be able to purchase or sell the Fund’s shares.

Financial Sector Risk. Performance of companies in the financial sector may be adversely impacted by many factors, including, among others, government regulations, economic conditions, credit rating downgrades, changes in interest rates, and decreased liquidity in credit markets. This sector has experienced significant losses in the recent past, and the impact of more stringent capital requirements and of recent or future regulation on any individual financial company or on the sector as a whole cannot be predicted.

Information Technology Sector Risk. Information technology companies face intense competition and potentially rapid product obsolescence. They are also heavily dependent on intellectual property rights and may be adversely affected by loss or impairment of those rights.

Interest Rate Risk. An increase in interest rates may cause the value of fixed-income securities held by the Fund or an Underlying Fund to decline.

Issuer Risk. Fund performance depends on the performance of individual securities to which the Fund or an Underlying Fund has exposure. Changes to the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA’s investment management strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares, losses from trading in secondary markets, periods of high volatility and disruption in the creation/redemption process of the

Fund. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV.

Mid-Capitalization Companies Risk. The Fund or an Underlying Fund invests in the securities of mid-capitalization companies. Compared to large-capitalization companies, mid-capitalization companies may be less stable and more susceptible to adverse developments and their securities may be more volatile and less liquid.

Model Risk. Neither the Fund nor BFA can offer assurances that the Underlying Index’s allocation model will maximize returns or minimize risk, or be appropriate for every investor seeking a particular risk profile.

Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers are subject to the risks associated with investing in those non-U.S. markets, such as heightened risks of inflation or nationalization. The Fund may lose money due to political, economic and geographic events affecting a non-U.S. issuer or market.

Passive Investment Risk. The Fund is not actively managed and BFA does not attempt to take defensive positions under any market conditions, including declining markets.

Reinvestment Risk. The Fund or an Underlying Fund invests in short-term fixed-income instruments and may be adversely affected if interest rates fall because it may invest in lower yielding bonds as bonds in the portfolio mature.

Risk of Investing in Russia. Investing in Russian securities involves significant risks, including legal, regulatory and economic risks that are specific to Russia. In addition, investing in Russian securities involves risks associated with the settlement of portfolio transactions and loss of the Fund’s ownership rights in its portfolio securities, as a result of the system of share registration and custody in Russia.

Securities Lending Risk. The Fund or an Underlying Fund may engage in securities lending. Securities lending involves the risk that the Fund or an Underlying Fund may lose money because the borrower of the Fund’s loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Small-Capitalization Companies Risk. The Fund or an Underlying Fund invests in the securities of small-capitalization companies. Compared to mid- and large-capitalization companies, small-capitalization companies may be less stable and more susceptible to adverse developments and their securities may be more volatile and less liquid.

Subsidiary Risk. By investing in the Subsidiary, the Fund is indirectly exposed to the risks associated with the Subsidiary’s investments. The commodity-related instruments that may be held by the Subsidiary are generally similar to those that are permitted to be held by the Fund and are subject to the same risks that would apply to similar investments if held directly by the Fund. There can be no assurance that the investment objective of the Subsidiary will be achieved. The Subsidiary is not registered under the 1940 Act, and, unless otherwise noted in this prospectus, is not subject to all the investor protections of the 1940 Act. Changes in the laws of the United States and/or the Cayman Islands could result in the inability of the Fund and/or the Subsidiary to operate as described in this prospectus and the Statement of Additional Information (“SAI”) and could adversely affect the Fund.

Tracking Error Risk. The performance of the Fund may diverge from that of the Underlying Index. Because the Fund employs a representative sampling strategy, the Fund may experience tracking error to a greater extent than a fund that seeks to replicate an index.

Treasury Obligations Risk. Treasury obligations may differ in their interest rates, maturities, times of issuance and other characteristics. Similar to other issuers, changes to the financial condition or credit rating of a government may cause the value of the Fund’s Treasury obligations to decline.

Valuation Risk. The value of the securities in the Fund’s portfolio may change on days when shareholders will not be able to purchase or sell the Fund’s shares.

Actual after-tax returns depend on an investor’s tax situation and may differ from those shown, and after-tax returns shown are not relevant to tax-exempt investors or investors who hold shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts (“IRAs”). Fund returns after taxes on distributions and sale of Fund shares are calculated assuming that an investor has sufficient capital gains of the same character from other investments to offset any capital losses from the sale of Fund shares. As a result, Fund returns after taxes on distributions and sale of Fund shares may exceed Fund returns before taxes and/or returns after taxes on distributions.

Management

Investment Adviser. BlackRock Fund Advisors.

Portfolio Managers. Rene Casis, Diane Hsiung and Greg Savage (the “Portfolio Managers”) are primarily responsible for the day-to-day management of the Fund. Each Portfolio Manager supervises a portfolio management team. Mr. Casis, Ms. Hsiung and Mr. Savage have been Portfolio Managers of the Fund since 2010, 2008 and 2008, respectively.

Purchase and Sale of Fund Shares

The Fund is an exchange-traded fund (commonly referred to as an “ETF”). Individual Fund shares may only be purchased and sold on a national securities exchange through a broker-dealer. The price of Fund shares is based on market price, and because ETF shares trade at market prices rather than NAV, shares may trade at a price greater than NAV (a premium) or less than NAV (a discount). The Fund will only issue or redeem shares that have been aggregated into blocks of 50,000 shares or multiples thereof (“Creation Units”) to authorized participants who have entered into agreements with the Fund’s distributor. The Fund generally will issue or redeem Creation Units in return for a designated portfolio of securities (and an amount of cash) that the Fund specifies each day.

Tax Information

The Fund intends to make distributions that may be taxable to you as ordinary income or capital gains, unless you are investing through a tax-deferred arrangement such as a 401(k) plan or an IRA.

Payments to Broker-Dealers and other Financial Intermediaries

If you purchase shares of the Fund through a broker-dealer or other financial intermediary (such as a bank), BFA or other related companies may pay the intermediary for marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems or other services related to the sale or promotion of the Funds. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Funds over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.

iShares S&P Aggressive Allocation Fund

iShares S&P Aggressive Allocation Fund

Ticker: AOA Stock Exchange: NYSE Arca

Investment Objective

The iShares S&P Aggressive Allocation Fund (the “Fund”) seeks investment results that correspond generally to the price and yield performance, before fees and expenses, of the S&P Target Risk Aggressive Index (the “Underlying Index”).

Fees and Expenses

The following table describes the fees and expenses that you will incur if you own shares of the Fund. The investment advisory agreement between iShares Trust (the “Trust”) and BlackRock Fund Advisors (“BFA”) (the “Investment Advisory Agreement”) provides that BFA will pay all operating expenses of the Fund, except interest expenses, taxes, brokerage expenses, future distribution fees or expenses, and extraordinary expenses. “Acquired Fund Fees and Expenses” reflect the Fund’s pro rata share of the fees and expenses incurred by investing in other investment companies. The impact of Acquired Fund Fees and Expenses is included in the total returns of the Fund. Acquired Fund Fees and Expenses are not used to calculate the Fund’s net asset value per share (“NAV”) and are not included in the calculation of the ratio of expenses to average net assets shown in the Financial Highlights section of the Fund’s prospectus (the “Prospectus”). BFA has contractually agreed to waive a portion of the advisory fee it is entitled to receive from the Fund due to its investments in other iShares funds, in an amount equal to 0.14%, through June 30, 2013. The contractual waiver may be terminated prior to June 30, 2013 only upon written agreement of the Trust and BFA.

You will also incur usual and customary brokerage commissions when buying or selling shares of the Fund, which are not reflected in the example that follows:

Example. This Example is intended to help you compare the cost of owning shares of the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

1 Year
3 Years
5 Years
10 Years
$34 $128 $241 $570

Portfolio Turnover. The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 13% of the average value of its portfolio.

Principal Investment Strategies

The Fund is a fund of funds and seeks its investment objective by investing primarily in the securities of other iShares funds (each, an “Underlying Fund” and collectively, the “Underlying Funds”) that themselves seek investment results corresponding to their own underlying index. The Underlying Funds invest primarily in distinct asset classes, such as large-capitalization U.S. equity, mid-capitalization U.S. equity, emerging market securities, the aggregate bond market or the U.S. treasury bond market; each such asset class has its own risk profile.

The Underlying Index measures the performance of S&P’s proprietary allocation model, which is intended to represent an “aggressive” target risk allocation strategy as defined by S&P. S&P’s estimation of an aggressive target risk allocation may differ from your own.

The Fund is designed for investors seeking long-term capital appreciation. In 2011, for the Underlying Index, S&P defined that as a 30% probability of losing at least 33% of its value. It is possible that an investor in the Fund could lose a significantly larger percentage of their investment. As of September 30, 2011, the Fund invested approximately 86.51% of its assets in Underlying Funds that invest primarily in equity securities, 13.40% of its assets in Underlying Funds that invest primarily in bonds and the remainder of its assets in Underlying Funds that invest primarily in money market instruments.

As of September 30, 2011, the Fund invested in the iShares S&P 500 Index Fund, iShares S&P MidCap 400 Index Fund, iShares S&P SmallCap 600 Index Fund, iShares MSCI EAFE Index Fund, iShares MSCI Emerging Markets Index Fund, iShares Barclays Aggregate Bond Fund, iShares Barclays TIPS Bond Fund, iShares iBoxx $ High Yield Corporate Bond Fund and BlackRock Cash Funds. BFA may add, eliminate or replace all Underlying Funds at any time.

Table Of Contents



BFA uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to “beat” the index it tracks and does not seek temporary defensive positions when markets decline or appear overvalued.

Indexing may eliminate the chance that the Fund will substantially outperform the Underlying Index but also may reduce some of the risks of active management, such as poor security selection. Indexing seeks to achieve lower costs and better after-tax performance by keeping portfolio turnover low in comparison to actively managed investment companies.

BFA uses a representative sampling indexing strategy to manage the Funds. “Representative sampling” is an indexing strategy that involves investing in a representative sample of securities that collectively has an investment profile similar to the Underlying Index. The securities selected are expected to have, in the aggregate, investment characteristics (based on factors such as market capitalization and industry weightings), fundamental characteristics (such as return variability and yield) and liquidity measures similar to those of the Underlying Index. The Fund may or may not hold all of the securities in the Underlying Index.

The Fund generally invests at least 90% of its assets in securities of the Underlying Index. The Fund may invest the remainder of its assets in securities not included in the Underlying Index, but which BFA believes will help the Fund track its Underlying Index and in other investments including futures contracts, options on futures contracts and options, as well as cash and cash equivalents, including shares of money market funds affiliated with BFA or its affiliates, to the extent permitted under the Investment Company Act of 1940, as amended (the “1940 Act”).

The Fund may lend securities representing up to one-third of the value of the Fund’s total assets (including the value of the collateral received).

The Underlying Index is sponsored by an organization (the “Index Provider”) that is independent of the Fund and BFA. The Index Provider determines the composition and relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index. The Fund’s Index Provider is Standard & Poor’s Financial Services LLC (a subsidiary of The McGraw-Hill Companies) (“S&P”).

Industry Concentration Policy. The Fund will concentrate its investments (i.e., hold 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. For purposes of this limitation, securities of the U.S. government (including its agencies and instrumentalities) and repurchase agreements collateralized by U.S. government securities are not considered to be issued by members of any industry.

Summary of Principal Risks

As with any investment, you could lose all or part of your investment in the Fund, and the Fund’s performance could trail that of other investments. The Fund is subject to the principal risks noted below (either directly or through its investments in the Underlying Funds), any of which may adversely affect the Fund’s NAV, trading price, yield, total return and ability to meet its investment objective.

Asset Class Risk. Securities in the Underlying Index or in the Fund’s portfolio may underperform in comparison to the general securities markets or other asset classes.

Consumer Discretionary Sector Risk. The consumer discretionary sector may be affected by changes in domestic and international economies, exchange and interest rates, competition, consumers’ disposable income and consumer preferences, social trends and marketing campaigns.

Credit Risk. The risk that debt issuers and other counterparties may not honor their obligations or may have their debt downgraded by ratings agencies.

Emerging Markets Risk. Investments in emerging markets may be subject to a greater risk of loss than investments in more developed markets. Emerging markets may be more likely to experience inflation risk, political turmoil and rapid changes in economic conditions than more developed markets. Emerging markets often have less uniformity in accounting and reporting requirements, unreliable securities valuation and greater risk associated with custody of securities.

Equity Securities Risk. Equity securities are subject to changes in value and their values may be more volatile than other asset classes.

Financial Sector Risk. Performance of companies in the financial sector may be adversely impacted by many factors, including, among others, government regulations, economic conditions, credit rating downgrades, changes in interest rates, and decreased liquidity in credit markets. This sector has experienced significant losses in the recent past, and the impact of more stringent capital requirements and of recent or future regulation on any individual financial company or on the sector as a whole cannot be predicted.

Industrials Sector Risk. The industrials sector is affected by changes in the supply and demand for products and services, product obsolescence, claims for environmental damage or product liability and general economic conditions, among other factors.

Information Technology Sector Risk. Information technology companies face intense competition and potentially rapid product obsolescence. They are also heavily dependent on intellectual property rights and may be adversely affected by loss or impairment of those rights.

Interest Rate Risk. An increase in interest rates may cause the value of fixed-income securities held by the Fund or an Underlying Fund to decline.

Issuer Risk. Fund performance depends on the performance of individual securities to which the Fund or an Underlying Fund has exposure. Changes to the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline.

Management Risk. As the Fund may not fully replicate the Underlying Index, it is subject to the risk that BFA’s investment management strategy may not produce the intended results.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares, losses from trading in secondary markets, periods of high volatility and disruption in the creation/redemption process of the Fund. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO THE FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV.

Mid-Capitalization Companies Risk. The Fund or an Underlying Fund invests in the securities of mid-capitalization companies. Compared to large-capitalization companies, mid-capitalization companies may be less stable and more susceptible to adverse developments and their securities may be more volatile and less liquid.

Model Risk. Neither the Fund nor BFA can offer assurances that the Underlying Index’s allocation model will maximize returns or minimize risk, or be appropriate for every investor seeking a particular risk profile.

Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers are subject to the risks associated with investing in those non-U.S. markets, such as heightened risks of inflation or nationalization. The Fund may lose money due to political, economic and geographic events affecting a non-U.S. issuer or market.

Passive Investment Risk. The Fund is not actively managed and BFA does not attempt to take defensive positions under any market conditions, including declining markets.

Reinvestment Risk. The Fund or an Underlying Fund invests in short-term fixed-income instruments and may be adversely affected if interest rates fall because it may invest in lower yielding bonds as bonds in the portfolio mature.

Risk of Investing in Russia. Investing in Russian securities involves significant risks, including legal, regulatory and economic risks that are specific to Russia. In addition, investing in Russian securities involves risks associated with the settlement of portfolio transactions and loss of the Fund’s ownership rights in its portfolio securities, as a result of the system of share registration and custody in Russia.

Securities Lending Risk. The Fund or an Underlying Fund may engage in securities lending. Securities lending involves the risk that the Fund or an Underlying Fund may lose money because the borrower of the Fund’s loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of the collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund.

Small-Capitalization Companies Risk. The Fund or an Underlying Fund invests in the securities of small-capitalization companies. Compared to mid- and large-capitalization companies, small-capitalization companies may be less stable and more susceptible to adverse developments and their securities may be more volatile and less liquid.

Subsidiary Risk. By investing in the Subsidiary, the Fund is indirectly exposed to the risks associated with the Subsidiary’s investments. The commodity-related instruments that may be held by the Subsidiary are generally similar to those that are permitted to be held by the Fund and are subject to the same risks that would apply to similar investments if held directly by the Fund. There can be no assurance that the investment objective of the Subsidiary will be achieved. The Subsidiary is not registered under the 1940 Act, and, unless otherwise noted in this prospectus, is not subject to all the investor protections of the 1940 Act. Changes in the laws of the United States and/or the Cayman Islands could result in the inability of the Fund and/or the Subsidiary to operate as described in this prospectus and the Statement of Additional Information (“SAI”) and could adversely affect the Fund.

Tracking Error Risk. The performance of the Fund may diverge from that of the Underlying Index. Because the Fund employs a representative sampling strategy, the Fund may experience tracking error to a greater extent than a fund that seeks to replicate an index.

Valuation Risk. The value of the securities in the Fund’s portfolio may change on days when shareholders will not be able to purchase or sell the Fund’s shares.

Purchase and Sale of Fund Shares

The Fund is an exchange-traded fund (commonly referred to as an “ETF”). Individual Fund shares may only be purchased and sold on a national securities exchange through a broker-dealer. The price of Fund shares is based on market price, and because ETF shares trade at market prices rather than NAV, shares may trade at a price greater than NAV (a premium) or less than NAV (a discount).

Payments to Broker-Dealers and other Financial Intermediaries

If you purchase shares of the Fund through a broker-dealer or other financial intermediary (such as a bank), BFA or other related companies may pay the intermediary for marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems or other services related to the sale or promotion of the Funds. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Funds over another investment.

More Information About the Funds

This Prospectus contains important information about investing in the Funds. Please read this Prospectus carefully before you make any investment decisions. Additional information regarding the Funds is available at www.iShares.com.

BFA is the investment adviser to the Funds. Shares of each Fund are listed for trading on NYSE Arca, Inc. (“NYSE Arca”). The market price for a share of a Fund may be different from the Fund’s most recent NAV. Each Fund has its own CUSIP number and exchange trading symbol.

ETFs are funds that trade like other publicly-traded securities and are designed to track an index. Similar to shares of an index mutual fund, each share of a Fund represents a partial ownership in an underlying portfolio of securities intended to track a market index. Unlike shares of a mutual fund, which can be bought and redeemed from the issuing fund by all shareholders at a price based on NAV, shares of the Funds may be purchased or redeemed directly from the Funds at NAV solely by authorized participants. Also unlike shares of a mutual fund, shares of each Fund are listed on a national securities exchange and trade in the secondary market at market prices that change throughout the day.

An index is a theoretical financial calculation while each Fund is an actual investment portfolio. The performance of each Fund and its Underlying Index may vary due to transaction costs, non-U.S. currency valuations, asset valuations, corporate actions (such as mergers and spin-offs), timing variances and differences between each Fund’s portfolio and its Underlying Index resulting from legal restrictions (such as diversification requirements) that apply to each Fund but not to its Underlying Index or to the use of representative sampling. “Tracking error” is the difference between the performance (return) of each Fund’s portfolio and that of its Underlying Index. BFA expects that, over time, each Fund’s tracking error will not exceed 5%. Because each Fund uses a representative sampling indexing strategy, it can be expected to have a larger tracking error than if it used a replication indexing strategy. “Replication” is an indexing strategy in which a fund invests in substantially all of the securities in its underlying index in approximately the same proportions as in the underlying index.

An investment in a Fund is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, BFA or any of its affiliates.

Each Fund’s investment objective and its Underlying Index may be changed without shareholder approval.

Each Fund may make commodity-related investments through investments in a wholly-owned subsidiary of the Fund formed in the Cayman Islands (the “Subsidiary”). The Subsidiary is managed by BFA. The assets of the Subsidiary are subject to the same investment restrictions and limitations, and follow the same compliance policies and procedures, as the Fund. The Fund will not invest more than 25% of its total assets (measured at the time of investment) in the Subsidiary.

Investment Objectives of the Funds

Each Fund seeks investment results that correspond generally to the price and yield performance, before fees and expenses, of an S&P Target Risk Index (each, an “Underlying Index” and collectively, the “Underlying Indexes”). Each Underlying Index is comprised entirely of securities of iShares funds (each, an “Underlying Fund” and collectively, the “Underlying Funds”) that themselves seek investment results that correspond generally to the price and yield performance, before fees and expenses, of their own respective underlying indexes. Each Fund is an ETF fund of funds and seeks its investment objective by investing primarily in the Underlying Funds.

The Underlying Indexes are designed to measure risk-adjusted exposure to a diversified array of financial assets. Each year, S&P estimates a value-weighted “market portfolio.” S&P’s “market portfolio” estimate is intended to represent a large proportion of globally traded stocks and bonds. Each Underlying Index is constructed to have high correlation with the market portfolio, subject to specific shortfall risk constraints for each target risk level. Each shortfall risk constraint is an estimation of the probability of attaining returns below a certain risk threshold. While S&P’s model is intended to constrain risk, actual losses may significantly exceed the target risk threshold. The shortfall risk constraints and target risk thresholds that S&P derived for each target risk index for 2011 are as follows:

   Conservative Moderate Growth Aggressive
Target Risk Threshold -21% -25% -30% -33%
Probability of Shortfall Risk 18% 22% 26% 30%

   Note: The above chart is for illustrative purposes and represents the actual allocation percentages of the Funds as of September 30, 2011, which are subject to change.

A Further Discussion of Principal Risks

Each Fund is subject to various risks, including the principal risks noted below, any of which may adversely affect the Fund’s NAV, trading price, yield, total return and ability to meet its investment objective. Each Fund may be exposed to these risks directly, or indirectly through the Fund’s investments in the Underlying Funds. You could lose all or part of your investment in the Funds, and the Funds could underperform other investments.

Asset Class Risk. The securities in the Underlying Index or in a Fund’s or Underlying Fund’s portfolio may underperform the returns of other securities or indexes that track other industries, groups of industries, markets, asset classes or sectors. Various types of securities or indexes tend to experience cycles of outperformance and underperformance in comparison to the general securities markets.

Consumer Discretionary Sector Risk. The success of consumer product manufacturers and retailers is tied closely to the performance of domestic and international economies, interest rates, exchange rates, competition, consumer confidence, changes in demographics and consumer preferences. Companies in the consumer discretionary sector depend heavily on disposable household income and consumer spending, and may be strongly affected by social trends and marketing campaigns. These companies may be subject to severe competition, which may have an adverse impact on their profitability.

Credit Risk. Credit risk is the risk that an issuer or guarantor of debt instruments or the counterparty to a derivatives contract, repurchase agreement or loan of portfolio securities will be unable or unwilling to make its timely interest and/or principal payments or to otherwise honor its obligations. Debt instruments are subject to varying degrees of credit risk, which may be reflected in their credit ratings. There is the chance that any of an Underlying Fund’s portfolio holdings will have their credit ratings downgraded or will default (fail to make scheduled interest or principal payments), potentially reducing such Underlying Fund’s income level or share price, which can adversely affect the value of Funds that invest in such Underlying Fund.

Emerging Markets Risk. Investments in emerging markets are subject to a greater risk of loss than investments in more developed markets. This is due to, among other things, the potential for greater market volatility, lower trading volume, inflation, political and economic instability, greater risk of a market shutdown and more governmental limitations on foreign investments than typically found in more developed markets. In addition, emerging markets often have less uniformity in accounting and reporting requirements, unreliable securities valuation and greater risks associated with custody of securities.

Local securities markets in emerging market countries may trade a small number of securities and may be unable to respond effectively to increases in trading volume, potentially making prompt liquidation of holdings difficult or impossible at times. Settlement procedures in emerging market countries are frequently less developed and reliable than those in the United States (and other developed countries). In addition, significant delays may occur in certain markets in registering the transfer of securities. Settlement or registration problems may make it more difficult for an Underlying Fund to value its portfolio securities and could cause an Underlying Fund to miss attractive investment opportunities.

Investing in emerging market countries involves a great risk of loss due to expropriation, nationalization, confiscation of assets and property or the imposition of restrictions on foreign investments and on repatriation of capital invested by certain emerging market countries.

Equity Securities Risk. Certain Underlying Funds invest in equity securities, which are subject to changes in value that may be attributable to market perception of a particular issuer or to general stock market fluctuations that affect all issuers. Investments in equity securities may be more volatile than investments in other asset classes.

Financial Sector Risk. Companies in the financial sector of an economy are often subject to governmental regulation and, recently, government intervention and the potential for additional regulation, which may adversely affect the scope of their activities, the prices they can charge and the amount of capital they must maintain. Governmental regulation may change frequently and may have significant adverse consequences for companies in the financial sector, including effects not intended by such regulation. The impact of recent or future regulation in various countries on any individual financial company or on the sector as a whole cannot be predicted. Certain risks may impact

the value of investments in the financial sector more severely than investments outside this sector, including the risks associated with companies that operate with substantial financial leverage. Companies in the financial sector may also be adversely affected by increases in interest rates and loan losses, decreases in the availability of money or asset valuations, credit rating downgrades and adverse conditions in other related markets. Over the past few years, the deterioration of the credit markets has impacted a broad range of mortgage, asset-backed, auction rate, sovereign debt and other markets, including U.S. and non-U.S. credit and interbank money markets, thereby affecting a wide range of financial institutions and markets. This situation has created instability in the financial markets and caused certain financial companies to incur large losses. Some financial companies have experienced declines in the valuations of their assets, taken actions to raise capital (such as the issuance of debt or equity securities), or even ceased operations. Some financial companies have borrowed significant amounts of capital from governments and may face future government-imposed restrictions on their businesses or increased government intervention. These actions have caused the securities of many financial companies to decline in value. Insurance companies, in particular, may be subject to severe price competition, which may have an adverse impact on their profitability.

Industrials Sector Risk. The stock prices of companies in the industrials sector are affected by supply and demand, both for their specific product or service and for industrials sector products in general. The products of manufacturing companies may face obsolescence due to rapid technological developments and frequent new product introduction. Government regulations, world events, economic conditions and exchange rates affect the performance of companies in the industrials sector. Companies in the industrials sector may be adversely affected by liability for environmental damage and product liability claims.

Information Technology Sector Risk. Information technology companies face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Like other technology companies, information technology companies may have limited product lines, markets, financial resources or personnel. The products of information technology companies may face obsolescence due to rapid technological developments and frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Companies in the information technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies.

Interest Rate Risk. As interest rates rise, the value of a fixed-income security held by an Underlying Fund is likely to decrease. Securities with longer durations tend to be more sensitive to interest rate changes, usually making them more volatile than securities with shorter durations. To the extent an Underlying Fund invests a substantial portion of its assets in fixed-income securities with longer-term maturities, rising interest rates may cause the value of such Underlying Fund’s investments to decline significantly, which can adversely affect the value of Funds that invest in such Underlying Fund. Prices of bonds may fall because of a rise in interest rates.

Issuer Risk. The performance of each Fund depends on the performance of individual securities to which the Fund has exposure. Any issuer of these securities may perform poorly, causing the value of its securities to decline. Poor performance may be caused by poor management decisions, competitive pressures, changes in technology, expiration of patent protection, disruptions in supply, labor problems or shortages, corporate restructurings, fraudulent disclosures or other factors. Issuers may, in times of distress or at their own discretion, decide to reduce or eliminate dividends, which may also cause their stock prices to decline.

Management Risk. Each Fund may not fully replicate its Underlying Index and may hold securities not included in its Underlying Index. As a result, a Fund is subject to the risk that BFA’s investment management strategy, the implementation of which is subject to a number of constraints, may not produce the intended results.

Market Risk. Each Fund could lose money due to short-term market movements and over longer periods during market downturns. Securities may decline in value due to factors affecting securities markets generally or particular industries represented in the markets. The value of a security may decline due to general market conditions, economic trends or events that are not specifically related to the issuer of the security or to factors that affect a particular industry or industries. During a general downturn in the securities markets, multiple asset classes may be negatively affected.

Market Trading Risk

Absence of Active Market. Although shares of the Funds are listed for trading on one or more stock exchanges, there can be no assurance that an active trading market for such shares will develop or be maintained.

Risk of Secondary Listings. The Funds’ shares may be listed or traded on U.S. and non-U.S. stock exchanges other than the U.S. stock exchange where the Fund’s primary listing is maintained. There can be no assurance that the Funds’ shares will continue to trade on any such stock exchange or in any market or that the Funds’ shares will continue to meet the requirements for listing or trading on any exchange or in any market. The Funds’ shares may be less actively traded in certain markets than others, and investors are subject to the execution and settlement risks and market standards of the market where they or their broker direct their trades for execution. Certain information available to investors who trade Fund shares on a U.S. stock exchange during regular U.S. market hours may not be available to investors who trade in other markets, which may result in secondary market prices in such markets being less efficient.

Secondary Market Trading Risk. Shares of a Fund may trade in the secondary market at times when the Funds do not accept orders to purchase or redeem shares. At such times, shares may trade in the secondary market with more significant premiums or discounts than might be experienced at times when the Funds accept purchase and redemption orders.

Secondary market trading in Fund shares may be halted by a stock exchange because of market conditions or other reasons. In addition, trading in Fund shares on a stock exchange or in any market may be subject to trading halts caused by extraordinary market volatility pursuant to “circuit breaker” rules on the stock exchange or market. There can be no assurance that the requirements necessary to maintain the listing or trading of Fund shares will continue to be met or will remain unchanged.

Shares of each Fund May Trade at Prices Other Than NAV. Shares of each Fund trade on stock exchanges at prices at, above or below their most recent NAV. The NAV of each Fund is calculated at the end of each business day and fluctuates with changes in the market value of such Fund’s holdings since the most recent calculation. The trading prices of a Fund’s shares fluctuate continuously throughout trading hours based on market supply and demand rather than NAV. The trading prices of a Fund’s shares may deviate significantly from NAV during periods of market volatility. ANY OF THESE FACTORS, AMONG OTHERS, MAY LEAD TO A FUND’S SHARES TRADING AT A PREMIUM OR DISCOUNT TO NAV. However, because shares can be created and redeemed in Creation Units at NAV (unlike shares of many closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their NAVs), BFA believes that large discounts or premiums to the NAV of a Fund are not likely to be sustained over the long-term. While the creation/redemption feature is designed to make it likely that a Fund’s shares normally will trade on stock exchanges at prices close to the Fund’s next calculated NAV, exchange prices are not expected to correlate exactly with a Fund’s NAV due to timing reasons as well as market supply and demand factors. In addition, disruptions to creations and redemptions or extreme market volatility may result in trading prices for shares of a Fund that differ significantly from its NAV.

Costs of Buying or Selling Fund Shares. Buying or selling Fund shares on an exchange involves two types of costs that apply to all securities transactions. When buying or selling shares of a Fund through a broker, you will likely incur a brokerage commission or other charges imposed by brokers as determined by that broker. In addition, you may incur the cost of the “spread” – that is, the difference between what investors are willing to pay for Fund shares (the “bid” price) and the price at which they are willing to sell Fund shares (the “ask” price). Because of the costs inherent in buying or selling Fund shares, frequent trading may detract significantly from investment results and an investment in Fund shares may not be advisable for investors who anticipate regularly making small investments.

Mid-Capitalization Companies Risk. Stock prices of mid-capitalization companies may be more volatile than those of large-capitalization companies and therefore the share price of an Underlying Fund that invests mostly in mid-capitalization companies may increase or decrease by a greater percentage than those of funds that invest solely in stocks issued by large-capitalization companies. Stock prices of mid-capitalization companies are also more vulnerable than large-capitalization stocks to adverse business or economic developments and the stocks of mid-capitalization companies may be less liquid, making it difficult for an Underlying Fund to buy and sell them. In addition, mid-capitalization companies generally have less diverse product lines than large-capitalization companies and are more susceptible to adverse developments related to their products.

Model Risk. Neither the Funds nor BFA can offer any assurance that the allocation model used to calculate the Underlying Indexes will either maximize returns or minimize risks in accordance with the targeted time horizon for each Underlying Index, nor can the Funds or BFA offer assurance that a particular allocation will be the appropriate allocation in all circumstances for every investor seeking a particular risk profile or time horizon.

Mortgage-Backed Securities Risk. Certain Underlying Funds invest in MBS issued by the Federal National Mortgage Association (“FNMA”), the Government National Mortgage Association (“GNMA”) or the Federal Home Loan Mortgage Corporation (“FHLMC”). While securities issued by GNMA are backed by the full faith and credit of the U.S. government, securities issued by FNMA and FHLMC are not backed by the full faith and credit of the U.S. government, and there can be no assurance that the U.S. government would provide financial support to its agencies or instrumentalities where it is not obligated to do so.

MBS are subject to prepayment risk, which is the risk that during periods of falling interest rates, an issuer of mortgages and other securities may be able to repay principal prior to the security’s maturity causing a Fund to have to reinvest in securities with a lower yield, resulting in a decline to a Fund’s income.

MBS are also subject to extension risk, which is the risk that when interest rates rise, certain MBS will be paid off substantially more slowly than originally anticipated and the value of those securities may fall sharply, resulting in a decline to the Fund’s income and potentially in the value of a Fund’s investments.

Because of prepayment and extension risk, MBS react differently to changes in interest rates than other bonds. Small movements in interest rates (both increases and decreases) may quickly and significantly reduce the value of certain MBS.

In recent years, the market for MBS experienced substantially lower valuations and greatly reduced liquidity. Ongoing economic and market uncertainty suggests that MBS may continue to be more difficult to value and to dispose of than previously.

Non-U.S. Securities Risk. Investments in the securities of non-U.S. issuers are subject to all of the risks of investing in the markets where such issuers are located, including heightened risks of inflation or nationalization and market fluctuations caused by economic and political developments. As a result of investing in non-U.S. securities, the Underlying Funds that invest in foreign securities may be subject to increased risk of loss caused by any of the factors listed below:

  • Lower levels of liquidity and market efficiency;
  • Greater securities price volatility;
  • Exchange rate fluctuations and exchange controls;
  • Less availability of public information about issuers;
  • Limitations on foreign ownership of securities;
  • Imposition of withholding or other taxes;
  • Imposition of restrictions on the expatriation of the funds or other assets of an Underlying Fund;
  • Higher transaction and custody costs and delays in settlement procedures;
  • Difficulties in enforcing contractual obligations;
  • Lower levels of regulation of the securities market;
  • Weaker accounting, disclosure and reporting requirements; and
  • Legal principles related to corporate governance, directors’ fiduciary duties and liabilities and stockholders’ rights in markets in which the Underlying Funds may invest may differ and/or may not be as extensive or protective as those that apply in the United States.

Passive Investment Risk. The Funds and Underlying Funds are not actively managed and may be affected by a general decline in market segments related to their Underlying Indexes. Each Fund and Underlying Fund invests in securities included in, or representative of, its Underlying Index regardless of their investment merits. BFA generally does not attempt to take defensive positions under any market conditions, including declining markets.

Reinvestment Risk. An Underlying Fund that invests mostly in short-term fixed-income instruments may be adversely affected when interest rates fall because it may invest in lower yielding bonds as bonds in its portfolio mature. This may cause the Underlying Fund’s income to decline, which may adversely affect the value of the Fund that invest in such Underlying Fund.

Risk of Investing in Russia. Investing in Russian securities involves significant risks, in addition to those described under “Emerging Markets Risk” and “Non-U.S. Securities Risk” that are not typically associated with investing in U.S. securities, including:

  • the risk of delays in settling portfolio transactions and the risk of loss arising out of the system of share registration and custody used in Russia;
  • risks in connection with the maintenance of a Fund’s portfolio securities and cash with foreign subcustodians and securities depositories, including the risk that appropriate sub-custody arrangements will not be available to the Fund;
  • the risk that a Fund’s ownership rights in portfolio securities could be lost through fraud or negligence as a result of the fact that ownership in shares of Russian companies is recorded by the companies themselves and by registrars, rather than by a central registration system; and
  • the risk that a Fund may not be able to pursue claims on behalf of its shareholders because of the system of share registration and custody, and because Russian banking institutions and registrars are not guaranteed by the government.

Securities Lending Risk. The Funds or the Underlying Funds may engage in securities lending. Securities lending involves the risk that the Funds or the Underlying Funds may lose money because the borrower of the Fund’s or Underlying Fund’s loaned securities fails to return the securities in a timely manner or at all. The Funds could also lose money in the event of a decline in the value of the collateral provided for the loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Funds.

Small-Capitalization Companies Risk. Many of the companies in which an Underlying Funds invests are considered small-capitalization companies. Stock prices of small-capitalization companies may be more volatile than those of larger companies and, therefore, the share price of an Underlying Fund that invests mostly in small-capitalization companies may be more volatile than those of funds that invest a larger percentage of their assets in stocks issued by mid- or large-capitalization companies. Stock prices of small-capitalization companies are generally more vulnerable than those of mid- or large-capitalization companies to adverse business and economic developments. Securities of small-capitalization companies may be thinly traded, making it difficult for the Underlying Funds to buy and sell them. In addition, small-capitalization companies are typically less financially stable than larger, more established companies and may depend on a small number of essential personnel, making them more vulnerable to loss of personnel. Small-capitalization companies also normally have less diverse product lines than mid- or large-capitalization companies and are more susceptible to adverse developments concerning their products.

Subsidiary Risk. By investing in a Subsidiary, each Fund is indirectly exposed to the risks associated with the Subsidiary’s investments. The commodity-related instruments that may be held by the Subsidiaries are generally similar to those that are permitted to be held by each Fund and are subject to the same risks that apply to similar investments if held directly by each Fund. There can be no assurance that the investment objective of the Subsidiaries will be achieved. The Subsidiaries are not registered under the 1940 Act, and, unless otherwise noted in this prospectus, are not subject to all the investor protections of the 1940 Act. The Board has oversight responsibility for the investment activities of each Fund, including its investment in the Subsidiaries, and each Fund’s role as sole shareholder of the Subsidiaries. The Subsidiaries will be subject to the same investment restrictions and limitations, and will follow the same compliance policies and procedures, as each Fund.

Each Fund has requested a private letter ruling from the U.S. Internal Revenue Service (“IRS”) confirming that the annual net profit, if any, realized by its Subsidiary and imputed for income tax purposes to the Fund will constitute “qualifying income” for purposes of the Fund remaining qualified as a regulated investment company for U.S. federal income tax purposes. The IRS has indicated that the granting of private letter rulings, like the one requested by each Fund, is currently suspended, pending further internal discussion. As a result, there can be no assurance that the IRS will grant the private letter ruling requested. If the IRS does not grant the private letter ruling request, there is a risk that the IRS could assert that the annual net profit realized by a Subsidiary and imputed for income tax purposes to a Fund will not be considered “qualifying income” for purposes of the Fund remaining qualified as a regulated investment company for U.S. federal income tax purposes. If a Fund fails to receive a private letter ruling, it may elect not to form or invest through a Subsidiary. Such an occurence may, in turn, reduce a Fund’s ability to gain investment exposure to commodities and track the performance of its Underlying Index. Moreover, changes in the laws of the United States and/or the Cayman Islands could result in the inability of each Fund and/or the Subsidiaries to operate as described in this prospectus and the SAI and could adversely affect each Fund. For example, the Cayman Islands does not

currently impose any income, corporate or capital gains taxes, estate duty, inheritance tax, gift tax or withholding tax on the Subsidiaries. If Cayman Islands law changes such that the Subsidiaries must pay Cayman Islands taxes, Fund shareholders would likely experience decreased investment returns.

Tracking Error Risk. Imperfect correlation between a Fund’s or Underlying Fund’s portfolio securities and those in its Underlying Index, rounding of prices, changes to its Underlying Index and regulatory requirements may cause tracking error, which is the divergence of a Fund’s performance from that of its Underlying Index. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because a Fund or Underlying Fund incurs fees and expenses, while its Underlying Index does not. Due to certain adverse tax consequences that may result from a Fund investing directly in commodities, each Fund may reduce its exposure to commodities to an amount below the current commodity exposure, if any, of its Underlying Index. This reduced commodity exposure, in turn, might result in, or exacerbate, a difference between the performance of the Fund and the performance of the Underlying Index. If a Fund receives a private letter ruling from the IRS, the Fund is expected to adjust its exposure to commodities in order to more closely align the holdings of the Fund with its Underlying Index. Because the Fund employs a representative sampling strategy, the Fund may experience tracking error to a greater extent than a fund that seeks to replicate an index.

Treasury Obligations Risk. Treasury obligations may differ from other issuances in their interest rates, maturities, times of issuance and other characteristics. Similar to other issuers, changes to the financial condition or credit rating of a government may cause the value of a Fund’s Treasury obligations to decline. On August 5, 2011, S&P downgraded U.S. Treasury securities from AAA rating to AA+. A downgrade of the ratings of U.S. government debt obligations, which are often used as a benchmark for other borrowing arrangements, could result in higher interest rates for individual and corporate borrowers, cause disruptions in the international bond markets and generally have a substantial negative effect on the U.S. economy. A downgrade of Treasury securities from another ratings agency or a further downgrade beyond AA+ rating by S&P may cause the value of a Fund’s Treasury obligations to decline.

Valuation Risk. Because non-U.S. exchanges may be open on days when an Underlying Fund does not price its shares, the value of the securities in an Underlying Fund’s portfolio may change on days when the Funds will not be able to purchase or sell an Underlying Fund’s shares. In addition, for purposes of calculating a Fund’s NAV, the value of assets denominated in non-U.S. currencies is converted into U.S. dollars using exchange rates deemed appropriate by BFA. This conversion may result in a difference between the prices used to calculate a Fund’s NAV and the prices used by its Underlying Index, which, in turn, could result in a difference between a Fund’s performance and the performance of the Underlying Index.

A Further Discussion of Other Risks

Each Fund may also be subject to certain other risks associated with its investments and investment strategies.

Asian Economic Risk. Certain Asian economies have experienced over-extension of credit, currency devaluations and restrictions, high unemployment, high inflation, decreased exports and economic recessions. Economic events in any one Asian country may have a significant economic effect on the entire Asian region, and on some or all of the countries in which the Funds or the Underlying Funds may invest.

Consumer Staples Sector Risk. The consumer staples sector may be affected by the permissibility of using various food additives and production methods, marketing campaigns and other factors affecting consumer demand. Tobacco companies, in particular, may be adversely affected by new laws, regulations and litigation. The consumer staples sector may also be adversely affected by changes or trends in commodity prices, which may be influenced or characterized by unpredictable factors.

Energy Sector Risk. The energy sector is cyclical and highly dependent on commodities prices. The market values of companies in the energy sector are strongly affected by the levels and volatility of global energy prices, energy supply and demand, capital expenditures on exploration and production, energy conservation efforts, exchange rates and technological advances, among other factors. Companies in this sector may be subject to substantial government regulation and contractual fixed pricing, which may increase the cost of business and limit these companies’ earnings. A significant portion of their revenues depends on a relatively small number of customers, including governmental entities and utilities. As a result, governmental budget constraints may have a material adverse effect on the stock prices of companies in this industry. Energy companies may also operate in countries with less developed regulatory regimes or a history of expropriation, nationalization or other adverse policies. Energy companies also face a significant risk of civil liability from accidents resulting in injury or loss of life or property, pollution or other environmental mishaps, equipment malfunctions or mishandling of materials and a risk of loss from terrorism and natural disasters. Any such event could have serious consequences for the general population of the area affected and result in a material adverse impact on a Fund’s portfolio and the performance of the Fund. Energy companies can be significantly affected by the supply of, and demand for, specific products (e.g., oil and natural gas) and services, exploration and production spending, government regulation, world events and general economic conditions.

European Economic Risk. The Economic and Monetary Union of the European Union (the “EU”) requires member countries to comply with restrictions on inflation rates, deficits, interest rates, debt levels and fiscal and monetary controls, each of which may significantly affect every country in Europe. Decreasing imports or exports, changes in governmental or EU regulations on trade, changes in the exchange rate of the euro, the default or threat of default by an EU member country on its sovereign debt, and/or an economic recession in an EU member country may have a significant adverse effect on the economies of EU member countries and their trading partners. The European financial markets have recently experienced volatility and have been adversely affected by concerns about economic downturns, credit rating downgrades, rising government debt levels and possible default on or restructuring of government debt in several European countries, including Greece, Ireland, Italy, Portugal and Spain. A default or debt restructuring by any European country would adversely impact holders of that country’s debt, and sellers of credit default swaps linked to that country’s creditworthiness, which may be located in countries other

than those listed in the previous sentence. These events have adversely affected the value and exchange rate of the euro and may continue to significantly affect the economies of every country in Europe, including EU member countries that do not use the euro and non-EU member countries.

Health Care Sector Risk. The profitability of companies in the health care sector may be affected by extensive government regulations, restrictions on government reimbursement for medical expenses, rising costs of medical products and services, pricing pressure, an increased emphasis on outpatient services, limited number of products, industry innovation, changes in technologies and other market developments. Many health care companies are heavily dependent on patent protection. The expiration of patents may adversely affect the profitability of these companies. Many health care companies are subject to extensive litigation based on product liability and similar claims. Health care companies are subject to competitive forces that may make it difficult to raise prices and, in fact, may result in price discounting. Many new products in the health care sector may be subject to regulatory approvals. The process of obtaining such approvals may be long and costly. Companies in the health care sector may be thinly capitalized and may be susceptible to product obsolescence.

Portfolio Holdings Information

A description of the Trust’s policies and procedures with respect to the disclosure of the Funds’ portfolio securities is available in the Funds’ combined Statement of Additional Information (“SAI”). The top holdings of each Fund can be found at www.iShares.com. Fund fact sheets provide information regarding each Fund’s top holdings and may be requested by calling 1-800-iShares (1-800-474-2737).

A Further Discussion of Principal Investment Strategies

Overview

Each Fund pursues a common strategy of allocating and reallocating its assets among the Underlying Funds consistent with the allocation and reallocation among the Underlying Funds in the Underlying Indexes as determined by S&P. In addition to investing in the Underlying Funds, each Fund may borrow, lend its portfolio securities to brokers, dealers and financial institutions, and may invest the collateral in certain short-term instruments either directly or through one or more money market funds, as described in greater detail in the Funds’ SAI.

Certain Underlying Funds may invest in foreign securities, emerging markets and debt instruments, which are subject to additional risks, as described in this Prospectus and the SAI. The investment model for the Underlying Indexes is intended to set an allocation at a distinct targeted risk level, which each Fund seeks to match.

The Underlying Funds

Each Fund seeks investment results that correspond generally to the price and yield performance, before fees and expenses, of an Underlying Index. A Fund’s allocation of assets to the Underlying Funds will generally closely reflect the allocation weights represented in the Underlying Index. The Underlying Indexes are designed to measure risk-adjusted exposure to a diversified array of financial assets. Each year, S&P estimates the value-weighted “market portfolio.” S&P’s market portfolio estimate is intended to represent a large proportion of globally traded stocks and bonds. Each target risk index is constructed to have high correlation with the “market portfolio,” subject to specific shortfall risk constraints for each target risk level.

The following table lists the Underlying Funds and the asset allocation for each Fund as of September 30, 2011. BFA allocates each Fund’s assets among the Underlying Funds in accordance with the Fund’s investment objective and policies. The asset allocation for each Fund will vary over time and BFA is not required to invest any Fund’s assets in each of the Underlying Funds or in any particular percentage in any given Underlying Fund.

In managing each of the Underlying Funds, BFA uses a representative sampling index strategy. Representative sampling is an indexing strategy that involves investing in a representative sample of securities that collectively have an investment profile similar to a specified benchmark index. Securities selected for the Underlying Funds are expected to have, in the aggregate, investment characteristics (based on factors such as market capitalization and industry weightings), fundamental characteristics (such as return variability and yield) and liquidity measures similar to those of the applicable underlying index. The Underlying Funds may or may not hold all of the securities that are included in their respective underlying index and may hold certain securities that are not included in their respective underlying indexes. Additional information regarding the Underlying Funds and their investment objectives is provided below.

The iShares S&P 500 Index Fund seeks investment results that correspond generally to the price and yield performance, before fees and expenses, of the S&P 500® . The S&P 500® measures the performance of the large-capitalization sector of the U.S. equity market.

The iShares S&P MidCap 400 Index Fund seeks investment results that correspond generally to the price and yield performance, before fees and expenses, of the S&P MidCap 400® Index. The S&P MidCap 400® Index measures the performance of the mid-capitalization sector of the U.S. equity market. The stocks in the S&P MidCap 400® Index have a market capitalization between $1 billion and $4.4 billion (which may fluctuate depending on the overall level of the equity markets) and are selected for liquidity and industry group representation.

The iShares S&P SmallCap 600 Index Fund seeks investment results that correspond generally to the price and yield performance, before fees and expenses, of the S&P SmallCap 600® Index. The S&P SmallCap 600® Index measures the performance of the small-capitalization sector of the U.S. equity market. The stocks in the S&P SmallCap 600® Index have a market capitalization between $300 million and $1.4 billion (which may fluctuate depending on the overall level of the equity markets) and are selected for liquidity and industry group representation.

The iShares MSCI EAFE Index Fund seeks investment results that correspond generally to the price and yield performance, before fees and expenses, of the MSCI EAFE Index. The MSCI EAFE Index has been developed by MSCI as an equity benchmark for its international stock performance. The MSCI EAFE Index includes stocks from Europe, Australasia and the Far East, and as of September 30, 2011, consisted of the following 22 developed market country indexes: Australia, Austria, Belgium, Denmark, Finland, France, Germany, Greece, Hong Kong, Ireland, Israel, Italy, Japan, the Netherlands, New Zealand, Norway, Portugal, Singapore, Spain, Sweden, Switzerland and the United Kingdom.

The iShares MSCI Emerging Markets Index Fund seeks investment results that correspond generally to the price and yield performance, before fees and expenses, of the MSCI Emerging Markets Index. The MSCI Emerging Markets Index is designed to measure equity market performance in the global emerging markets. As of September 30, 2011, the MSCI Emerging Markets Index consisted of the following 20 emerging market country indexes: Brazil, Chile, China, Colombia, the Czech Republic, Egypt, Hungary, India, Indonesia, Malaysia, Mexico, Peru, the Philippines, Poland, Russia, South Africa, South Korea, Taiwan, Thailand and Turkey.

Emerging market country indexes may be added to or deleted from the MSCI Emerging Markets Index from time to time. In order to improve its portfolio liquidity and its ability to track the MSCI Emerging Markets Index, the iShares MSCI Emerging Markets Index Fund may invest up to 10% of its assets in shares of other iShares funds that seek to track the performance of equity securities in constituent countries of the MSCI Emerging Markets Index. BFA will waive portfolio management fees in an amount equal to the portfolio management fees of such other iShares funds for any portion of the iShares MSCI Emerging Markets Index Fund’s assets invested in shares of such other iShares funds.

The iShares Barclays Aggregate Bond Fund seeks investment results that correspond generally to the price and yield performance, before fees and expenses, of the Barclays Capital U.S. Aggregate Index (the “Barclays Capital Index”). The Barclays Capital Index measures the performance of the total United States investment grade bond market, which includes investment grade U.S. Treasury bonds, government-related bonds, investment grade corporate bonds, mortgage pass-through securities, commercial mortgage-backed securities and asset-backed securities that are publicly offered for sale in the United States. The securities in the Barclays Capital Index have $250 million or more of outstanding face value and must have at least one year remaining to maturity. In addition, the securities must be denominated in U.S. dollars and must be fixed-rate and non-convertible. Certain types of securities, such as state and local government series bonds, structured notes with embedded swaps or other special features, private placements, floating-rate securities and Eurobonds are excluded from the Barclays Capital Index.

The iShares Barclays Short Treasury Bond Fund seeks investment results that correspond generally to the price and yield performance, before fees and expenses, of the Barclays Capital U.S. Short Treasury Bond Index. The Barclays Capital U.S. Short Treasury Bond Index measures the performance of public obligations of the U.S. Treasury that have a remaining maturity of between one and 12 months.

The iShares Barclays TIPS Bond Fund seeks investment results that correspond generally to the price and yield performance, before fees and expenses, of the Barclays Capital U.S. Treasury Inflation Protected Securities (TIPS) Index (Series-L). The Barclays Capital U.S. Treasury Inflation Protected Securities (TIPS) Index (Series-L) measures the performance of the inflation-protected public obligations of the U.S. Treasury, commonly known as “TIPS.”

The iShares iBoxx $ High Yield Corporate Bond Fund seeks investment results that correspond generally to the price and yield performance, before fees and expenses, of the iBoxx® $ Liquid High Yield Index. The iBoxx® $ Liquid High Yield Index is a rules-based index consisting of liquid U.S. dollar-denominated, high yield corporate bonds for sale in the United States, as determined by the index provider.

Management

Investment Adviser. As investment adviser, BFA has overall responsibility for the general management and administration of the Trust. BFA provides an investment program for each Fund and manages the investment of each Fund’s assets. In managing the Funds, BFA may draw upon the research and expertise of its asset management affiliates with respect to certain portfolio securities. In seeking to achieve a Fund’s investment objective, BFA uses teams of portfolio managers, investment strategists and other investment specialists. This team approach brings together many disciplines and leverages BFA’s extensive resources.

Pursuant to the Investment Advisory Agreement between BFA and the Trust (entered into on behalf of the Funds), BFA is responsible for substantially all expenses of the Funds, except interest expenses, taxes, brokerage expenses, future distribution fees or expenses and extraordinary expenses.

For its investment advisory services to each Fund, BFA is entitled to receive a management fee from each Fund based on a percentage of a Fund’s average daily net assets, at the annual rate of 0.25%. BFA has entered into a Fee Waiver Agreement with the Trust, under which BFA agrees to waive a portion of the management fee that it is entitled to receive from each Fund in an amount equal to 0.14%. The Fee Waiver Agreement remains in effect until June 30, 2013. After giving effect to the fee waiver, BFA will receive a management fee based on a percentage of each Fund’s average daily net assets, at the annual rate of 0.11%. BFA will also receive additional revenue from the Underlying Funds as a result of the Funds’ investment in the Underlying Funds (the “Acquired Fund Fees and Expenses”).

BFA is located at 400 Howard Street, San Francisco, CA 94105. It is a wholly owned subsidiary of BTC, which in turn is indirectly wholly-owned by BlackRock, Inc. (“BlackRock”). As of September 30, 2011, BTC and its affiliates, including BFA and BlackRock, provided investment advisory services for assets in excess of $3.35 trillion. BFA, BTC, BlackRock Execution Services, BlackRock and their affiliates deal, trade and invest for their own accounts in the types of securities in which the Funds may also invest.

A discussion regarding the basis for the Trust’s Board of Trustees’ (the “Board”) approval of the Investment Advisory Agreement with BFA is available in each Fund’s annual report for the period ended July 31.

Portfolio Managers. Rene Casis, Diane Hsiung and Greg Savage are primarily responsible for the day-to-day management of the Funds. Each Portfolio Manager is responsible for various functions related to portfolio management, including, but not limited to, investing cash inflows, coordinating with members of his or her portfolio management team to focus on certain asset classes, implementing investment strategy, researching and reviewing investment strategy and overseeing members of his or her portfolio management team that have more limited responsibilities.

Rene Casis has been employed by BFA (formerly, Barclays Global Fund Advisors (“BGFA”)) and BTC (formerly, Barclays Global Investors, N.A. (“BGI”)) as a senior portfolio manager since 2009. From 2005 to 2009, Mr. Casis was a trader at Barclays Capital. Prior to that, Mr. Casis was a portfolio manager from 2000 to 2005 for BGFA and BGI. Mr. Casis has been a Portfolio Manager of each Fund since 2010.

Diane Hsiung has been employed by BFA and BTC as a senior portfolio manager since 2007. Prior to that, Ms. Hsiung was a portfolio manager from 2002 to 2006 for BGFA and BGI. Ms. Hsiung has been a Portfolio Manager of each Fund since 2008.

Greg Savage has been employed by BFA and BTC as a senior portfolio manager since 2006. Prior to that, Mr. Savage was a portfolio manager from 2001 to 2006 for BGFA and BGI. Mr. Savage has been a Portfolio Manager of each Fund since 2008.

The Funds’ SAI provides additional information about the Portfolio Managers’ compensation, other accounts managed by the Portfolio Managers and the Portfolio Managers’ ownership (if any) of shares in the Funds.

Administrator, Custodian and Transfer Agent. State Street Bank and Trust Company (“State Street”) is the administrator, custodian and transfer agent for each Fund.

Conflicts of Interest. BFA wants you to know that there are certain entities with which BFA has relationships that may give rise to conflicts of interest, or the appearance of conflicts of interest. These entities include the following: BFA’s affiliates (including BlackRock and The PNC Financial Services Group, Inc., and each of their affiliates, directors, partners, trustees, managing members, officers and employees (collectively, the “Affiliates”)) and BlackRock’s significant shareholder, Barclays Bank PLC and its affiliates, including Barclays PLC (each, an “Entity” and together, the “Entities”).

The activities of BFA, the Affiliates and the Entities in the management of, or their interest in, their own accounts and other accounts they manage, may present conflicts of interest that could disadvantage the Funds and their shareholders. BFA and its Affiliates or the Entities provide investment management services to other funds and discretionary managed accounts that may follow an investment program similar to that of the Funds. BFA, its Affiliates and the Entities are involved worldwide with a broad spectrum of financial services and asset management activities and may engage in the ordinary course of business in activities in which their interests or the interests of their clients may conflict with those of the Funds. BFA, one or more of the Affiliates or the Entities acts, or may act, as an investor, investment banker, research provider, investment manager, financier, underwriter, advisor, market maker, trader, prime broker, lender, agent or principal, and have other direct and indirect interests, in securities, currencies and other instruments in which the Funds may directly or indirectly invests. Thus, it is likely that the Funds will have multiple business relationships with and will invest in, engage in transactions with, make voting decisions with respect to, or obtain services from, entities for which BFA, an Affiliate or an Entity performs or seeks to perform investment banking or other services.

BFA or one or more Affiliates or Entities may engage in proprietary trading and advise accounts and funds that have investment objectives similar to those of the Funds and/or that engage in and compete for transactions in the same types of securities, currencies and other instruments as the Funds, including in securities issued by other open-end and closed-end investment management companies, including investment companies that are affiliated with the Funds and BFA, to the extent permitted under the 1940 Act. The trading activities of BFA, these Affiliates and Entities are carried out without reference to positions held directly or indirectly by the Funds and may result in BFA, an Affiliate or an Entity having positions that are adverse to those of the Funds.

No Affiliate or Entity is under any obligation to share any investment opportunity, idea or strategy with the Funds. As a result, an Affiliate or an Entity may compete with the Funds for appropriate investment opportunities. As a result of this and several other factors, the results of the Funds’ investment activities may differ from those of an Affiliate or an Entity and of other accounts managed by an Affiliate or an Entity, and it is possible that the Funds could sustain losses during periods in which one or more Affiliates or Entities and other accounts achieve profits on their trading for proprietary or other accounts. The opposite result is also possible.

The Funds may, from time to time, enter into transactions in which BFA or an Affiliate’s or an Entity’s clients have an interest adverse to the Funds. Furthermore, transactions undertaken by Affiliate-advised clients may adversely impact the Funds. Transactions by one or more Affiliate- or Entity-advised clients or BFA may have the effect of diluting or otherwise disadvantaging the values, prices or investment strategies of the Funds.

An Entity may maintain securities indices as part of their product offerings. Index-based funds seek to track the performance of securities indices and may use the name of the index in the fund name. Index providers, including the Entities, may be paid licensing fees for use of their indices or index names. Entities will not be obligated to license their indices to BFA and its Affiliates, and BFA and its Affiliates will not be assured that the terms of any index licensing agreement with the Entities will be as favorable as those terms offered to other index licensees.

The Funds’ activities may be limited because of regulatory restrictions applicable to one or more Affiliates or Entities, and/or their internal policies designed to comply with such restrictions. In addition, the Funds may invest in securities of companies with which an Affiliate or an Entity has or is trying to develop investment banking relationships or in which an Affiliate or an Entity has significant debt or equity investments. The Funds also may invest in securities of companies for which an Affiliate or an Entity provides or may some day provide research coverage. An Affiliate or an Entity may have business relationships with and purchase or distribute or sell services or products from or to distributors, consultants or others who recommend the Funds or who engage in transactions with or for the Funds, and may receive compensation for such services. The Funds may also make brokerage and other payments to Affiliates or Entities in connection with the Funds’ portfolio investment transactions.

Pursuant to a securities lending program approved by the Board, the Funds have retained an Affiliate of BFA to serve as the securities lending agent for the Funds to the extent that the Funds participate in the securities lending program. For these services, the lending agent may receive a fee from the Funds, including a fee based on the returns earned on the Funds’ investment of the cash received as collateral for any

loaned securities. In addition, one or more Affiliates may be among the entities to which the Funds may lend its portfolio securities under the securities lending program.

The activities of BFA, the Affiliates or Entities may give rise to other conflicts of interest that could disadvantage the Funds and their shareholders. BFA has adopted policies and procedures designed to address these potential conflicts of interest. See the Funds’ SAI for further information.

Shareholder Information

Additional shareholder information, including how to buy and sell shares of the Funds, is available free of charge by calling toll-free: 1-800-iShares (1-800-474-2737) or visiting our website at www.iShares.com.

Buying and Selling Shares. Shares of the Funds may be acquired or redeemed directly from a Fund only in Creation Units or multiples thereof, as discussed in the Creations and Redemptions section of this Prospectus. Only an Authorized Participant (as defined in the Creations and Redemptions section) may engage in creation or redemption transactions directly with the Fund. Once created, shares of the Funds generally trade in the secondary market in amounts less than a Creation Unit.

Shares of each Fund are listed on a national securities exchange for trading during the trading day. Shares can be bought and sold throughout the trading day like shares of other publicly-traded companies. The Trust does not impose any minimum investment for shares of a Fund purchased on an exchange. The Funds’ shares trade under the trading symbols listed in the Description of the Funds section of this Prospectus.

Buying or selling Fund shares on an exchange involves two types of costs that may apply to all securities transactions. When buying or selling shares of the Funds through a broker, you will likely incur a brokerage commission or other charges determined by your broker. The commission is frequently a fixed amount and may be a significant proportional cost for investors seeking to buy or sell small amounts of shares. In addition, you may incur the cost of the “spread” – that is, any difference between the bid price and the ask price. The spread varies over time for shares of each Fund based on their trading volume and market liquidity, and is generally lower if a Fund has a lot of trading volume and market liquidity, and higher if a Fund has little trading volume and market liquidity.

The Board has adopted a policy of not monitoring for frequent purchases and redemptions of Fund shares (“frequent trading”) that appear to attempt to take advantage of a potential arbitrage opportunity presented by a lag between a change in the value of a Fund’s portfolio securities after the close of the primary markets for a Fund’s portfolio securities and the reflection of that change in the Fund’s NAV (“market timing”), because each Fund generally sells and redeems its shares directly through transactions that are in-kind and/or for cash, subject to the conditions described below under Creations and Redemptions. The Board has not adopted a policy of monitoring for other frequent trading activity because shares of the Funds are listed for trading on a national securities exchange.

The national securities exchange on which each Fund’s shares are listed is open for trading Monday through Friday and is closed on weekends and the following holidays: New Year’s Day, Martin Luther King, Jr. Day, Presidents’ Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day. Each Fund’s primary listing exchange is NYSE Arca.

Book Entry. Shares of the Funds are held in book-entry form, which means that no stock certificates are issued. The Depository Trust Company (“DTC”) or its nominee is the record owner of all outstanding shares of each Fund and is recognized as the owner of all shares for all purposes.

Investors owning shares of the Funds are beneficial owners as shown on the records of DTC or its participants. DTC serves as the securities depository for shares of the Funds. DTC participants include securities brokers and dealers, banks, trust companies, clearing corporations and other institutions that directly or indirectly maintain a custodial relationship with DTC. As a beneficial owner of shares, you are not entitled to receive physical delivery of stock certificates or to have shares registered in your name, and you are not considered a registered owner of shares. Therefore, to exercise any right as an owner of shares, you must rely upon the procedures of DTC and its participants. These procedures are the same as those that apply to any other securities that you hold in book-entry or “street name” form.

Share Prices. The trading prices of a Fund’s shares in the secondary market generally differ from the Fund’s daily NAV and are affected by market forces such as supply and demand, economic conditions and other factors. Information regarding the intraday value of shares of each Fund, also known as the “indicative optimized portfolio value” (“IOPV”), is disseminated every 15 seconds throughout the trading day by the national securities exchange on which the Fund’s shares are listed or by market data vendors or other information providers. The IOPV is based on the current market value of the securities and/or cash required to be deposited in exchange for a Creation Unit. The IOPV does not necessarily reflect the precise composition of the current portfolio of securities held by a Fund at a particular point in time or the best possible valuation of the current portfolio. Therefore, the IOPV should not be viewed as a “real-time” update of each Fund’s NAV, which is computed only once a day. The IOPV is generally determined by using both current market quotations and/or price quotations obtained from broker-dealers that may trade in the portfolio securities held by the Funds. The quotations of certain Fund holdings may not be updated during U.S. trading hours if such holdings do not trade in the United States. The Funds are not involved in, or responsible for, the calculation or dissemination of the IOPV and make no representation or warranty as to its accuracy.

Determination of Net Asset Value. The NAV for each Fund normally is determined once daily Monday through Friday, generally as of the regularly scheduled close of business of the New York Stock Exchange (“NYSE”) (normally 4:00 p.m., Eastern time) on each day that the NYSE is open for trading, based on prices at the time of closing provided that (a) any Fund assets or liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the prevailing market rates on the date of valuation as quoted by one or more data service providers (as detailed below) and (b) U.S. fixed income assets may be valued as of the announced closing time for trading in fixed income instruments in a particular market or exchange. The NAV of each Fund is calculated by dividing the value of the net

assets of a Fund (i.e., the value of its total assets, which includes the net asset values of the Underlying Fund shares in which a Fund invests, less total liabilities) by the total number of outstanding shares of the Fund, generally rounded to the nearest cent.

The value of the securities and other assets held by the Fund, and its liabilities, are determined pursuant to valuation policies and procedures approved by the Board. The Fund’s assets and liabilities are valued primarily on the basis of market quotations.

Equity investments are valued at market value, which is generally determined using the last reported official closing price or last trading price on the exchange or market on which the security is primarily traded at the time of valuation.

Generally, trading in foreign securities, U.S. government securities, money market instruments and certain fixed-income securities is substantially completed each day at various times prior to the close of business on the NYSE. The values of such securities used in computing the NAV of the Funds are determined as of such times.

When market quotations are not readily available or are believed by BFA to be unreliable, the Fund’s investments are valued at fair value. Fair value determinations are made by BFA in accordance with policies and procedures approved by the Fund’s Board. BFA may conclude that a market quotation is not readily available or is unreliable if a security or other asset or liability does not have a price source due to its lack of liquidity, if a market quotation differs significantly from recent price quotations or otherwise no longer appears to reflect fair value, where the security or other asset or liability is thinly traded, or where there is a significant event subsequent to the most recent market quotation. A “significant event” is an event that, in the judgment of BFA, is likely to cause a material change to the closing market price of the asset or liability held by the Fund. Foreign securities whose values are affected by volatility that occurs in U.S. markets on a trading day after the close of foreign securities markets may be fair valued.

Fair value represents a good faith approximation of the value of an asset or liability. The fair value of an asset or liability held by the Fund is the amount the Fund might reasonably expect to receive from the current sale of that asset or the cost to extinguish that liability in an arm’s-length transaction. Valuing the Fund’s investments using fair value pricing will result in prices that may differ from current market valuations and that may not be the price at which those investments could have been sold during the period in which the particular fair values were used. Use of fair value prices and certain current market valuations could result in a difference between the prices used to calculate the Fund’s NAV and the prices used by the Underlying Index, which, in turn, could result in a difference between the Fund’s performance and the performance of the Underlying Index.

Dividends and Distributions

General Policies. Dividends from net investment income, if any, generally are declared and paid at least monthly by each Fund. Each Fund generally distributes its net capital gains, if any, to shareholders annually. Distributions of net realized securities gains, if any, generally are declared and paid once a year, but the Trust may make distributions on a more frequent basis for each Fund. The Trust reserves the right to declare special distributions if, in its reasonable discretion, such action is necessary or advisable to preserve its status as a regulated investment company (“RIC”) or to avoid imposition of income or excise taxes on undistributed income or realized gains.

Dividends and other distributions on shares of each Fund are distributed on a pro rata basis to beneficial owners of such shares. Dividend payments are made through DTC participants and indirect participants to beneficial owners then of record with proceeds received from a Fund.

Dividend Reinvestment Service. No dividend reinvestment service is provided by the Trust. Broker-dealers may make available the DTC book-entry Dividend Reinvestment Service for use by beneficial owners of a Fund for reinvestment of their dividend distributions. Beneficial owners should contact their broker to determine the availability and costs of the service and the details of participation therein. Brokers may require beneficial owners to adhere to specific procedures and timetables. If this service is available and used, dividend distributions of both income and realized gains will be automatically reinvested in additional whole shares of a Fund purchased in the secondary market.

Taxes. As with any investment, you should consider how your investment in shares of the Funds will be taxed. The tax information in this Prospectus is provided as general information, based on current law. You should consult your own tax professional about the tax consequences of an investment in shares of the Funds.

Unless your investment in Fund shares is made through a tax-exempt entity or tax-deferred retirement account, such as an IRA, you need to be aware of the possible tax consequences when a Fund makes distributions or you sell Fund shares.

Taxes on Distributions. Distributions from a Fund’s net investment income (other than qualified dividend income), including distributions of income from securities lending and distributions out of the Fund’s net short-term capital gains, if any, are taxable to you as ordinary income. Distributions by a Fund of net long-term capital gains in excess of net short-term capital losses (capital gain dividends) are taxable to you as long-term capital gains, generally at a 15% tax rate (0% at certain income levels), regardless of how long you have held a Fund’s shares. Distributions by a Fund that qualify as qualified dividend income are taxable to you at long-term capital gain rates for taxable years beginning on or before December 31, 2012. The 15% and 0% tax rates expire for taxable years beginning after December 31, 2012. Maximum long-term capital gain income tax rates are scheduled to rise to 20% in 2013. Beginning in 2013, a 3.8% U.S. federal Medicare contribution tax will be imposed on “net investment income,” including interest, dividends, and capital gains, of U.S. individuals with income exceeding $200,000 (or $250,000 if married and filing jointly), and of estates and trusts.

Dividends will be qualified dividend income to you if they are attributable to qualified dividend income received by a Fund. Generally, qualified dividend income includes dividend income from taxable U.S. corporations, provided that a Fund satisfies certain holding period requirements in respect of the stock of such corporations and has not hedged its position in the stock in certain ways. Substitute dividends received by a Fund with respect to dividends paid on securities lent out will not be qualified dividend income. For this purpose, a qualified non-U.S. corporation means any non-U.S. corporation that is eligible for benefits under a comprehensive income tax treaty with the United States,

which includes an exchange of information program or if the stock with respect to which the dividend was paid is readily tradable on an established United States securities market. The term excludes a corporation that is a passive foreign investment company.

Dividends received by a Fund from a REIT or another RIC generally are qualified dividend income only to the extent the dividend distributions are made out of qualified dividend income received by such REIT or RIC. It is expected that dividends received by a Fund from a REIT and distributed to a shareholder generally will be taxable to the shareholder as ordinary income.

For a dividend to be treated as qualified dividend income, the dividend must be received with respect to a share of stock held without being hedged by an Underlying Fund, and with respect to a share of an Underlying Fund held by a Fund without being hedged by a Fund, or to any share of a Fund held without being hedged by you, for 61 days during the 121-day period beginning at the date which is 60 days before the date on which such share becomes ex-dividend with respect to such dividend or, in the case of certain preferred stock, 91 days during the 181-day period beginning 90 days before such date.

If your Fund shares are loaned out pursuant to a securities lending arrangement, you may lose the ability to use foreign tax credits passed through by the Fund or to treat Fund dividends paid while the shares are held by the borrower as qualified dividend income.

In general, your distributions are subject to U.S. federal income tax for the year when they are paid. Certain distributions paid in January, however, may be treated as paid on December 31 of the prior year.

Short-term capital gain earned by an Underlying Fund will be ordinary income when distributed to a Fund and will not be offset by the Fund’s capital losses.

If a Fund’s distributions exceed current and accumulated earnings and profits, all or a portion of the distributions made in the taxable year may be recharacterized as a return of capital to shareholders. A return of capital distribution generally will not be taxable but will reduce the shareholder’s cost basis and result in a higher capital gain or lower capital loss when those shares on which the distribution was received are sold. Once a shareholder’s cost basis is reduced to zero, further distributions will be treated as capital gain, if the shareholder holds shares of the Fund as capital assets.

If you are neither a resident nor a citizen of the United States or if you are a non-U.S. entity, a Fund’s ordinary income dividends (which include distributions of net short-term capital gains) will generally be subject to a 30% U.S. withholding tax, unless a lower treaty rate applies, provided that withholding tax will generally not apply to any gain or income realized by a non-U.S. shareholder in respect of any distributions of long-term capital gains or upon the sale or other disposition of shares of a Fund.

A 30% withholding tax will be imposed on dividends paid after December 31, 2013, and redemption proceeds paid after December 31, 2014, to (i) foreign financial institutions including non-U.S. investment funds unless they agree to collect and disclose to the IRS information regarding their direct and indirect U.S. account holders and (ii) certain other foreign entities, unless they certify certain information regarding their direct and indirect U.S. owners. To avoid withholding, foreign financial institutions will need to enter into agreements with the IRS that state that they will provide the IRS information, including the name, address and taxpayer identification number of direct and indirect U.S. account holders, comply with due diligence procedures with respect to the identification of U.S. accounts, report to the IRS certain information with respect to U.S. accounts maintained, agree to withhold tax on certain payments made to non-compliant foreign financial institutions or to account holders who fail to provide the required information, and determine certain other information as to their account holders. Other foreign entities will need to provide the name, address, and taxpayer identification number of each substantial U.S. owner or certifications of no substantial U.S. ownership unless certain exceptions apply.

Dividends, interest and capital gains received by the Underlying Funds with respect to non-U.S. securities may give rise to withholding and other taxes imposed by non-U.S. countries which may reduce returns. Tax conventions between certain countries and the United States may reduce or eliminate such taxes. If not more than 50% of the total assets of the Fund at the close of a year consists of non-U.S. stocks or securities, the Fund may not “pass through” to you certain non-U.S. income taxes (including withholding taxes) paid by the Fund.

As the Funds invest in only a limited number of positions, the Funds may be required to defer for tax purposes significant amounts of realized losses on the sale of shares in Underlying Funds indefinitely.

If you are a resident or a citizen of the United States, by law, back-up withholding will apply to your distributions and proceeds if you have not provided a taxpayer identification number or social security number and made other required certifications.

Taxes When Shares are Sold. Currently, any capital gain or loss realized upon a sale of Fund shares is generally treated as a long-term gain or loss if the shares have been held for more than one year. Any capital gain or loss realized upon a sale of Fund shares held for one year or less is generally treated as short-term gain or loss, except that any capital loss on the sale of shares held for six months or less is treated as long-term capital loss to the extent that capital gain dividends were paid with respect to such shares. Beginning in 2013, any such capital gains, including from sales of Fund shares or from capital gain dividends, will be included in “net investment income” for purposes of the 3.8% U.S. federal Medicare contribution tax mentioned above.

The foregoing discussion summarizes some of the consequences under current U.S. federal tax law of an investment in a Fund. It is not a substitute for personal tax advice. You may also be subject to state and local taxation on Fund distributions and sales of shares. Consult your personal tax adviser about the potential tax consequences of an investment in shares of a Fund under all applicable tax laws.

Creations and Redemptions. Prior to trading in the secondary market, shares of each Fund are “created” at NAV by market makers, large investors and institutions only in block-size Creation Units of 50,000 shares or multiples thereof. Each “creator” or “Authorized Participant” enters into an authorized participant agreement with the Fund’s distributor, SEI Investments Distribution Co. (the “Distributor”). Only an Authorized Participant may create or redeem Creation Units directly with a Fund. A creation transaction, which is subject to acceptance by

the transfer agent, generally takes place when an Authorized Participant deposits into a Fund a designated portfolio of securities approximating the holdings of the Fund and a specified amount of cash in exchange for a specified number of Creation Units. To the extent practicable, the composition of such portfolio generally corresponds pro rata to the holdings of the Fund.

Similarly, shares can be redeemed only in Creation Units, generally for a designated portfolio of securities and a specified amount of cash held by the Fund (“Fund Securities”). Except when aggregated in Creation Units, shares are not redeemable by the Funds. The prices at which creations and redemptions occur are based on the next calculation of NAV after an order is received in a form described in the authorized participant agreement.

Each Fund intends to comply with the U.S. federal securities laws in accepting securities for deposits and satisfying redemptions with redemption securities by, among other means, assuring that any securities accepted for deposits and any securities used to satisfy redemption requests will be sold in transactions that would be exempt from registration under the Securities Act of 1933, as amended (the “1933 Act”). Further, an Authorized Participant that is not a “qualified institutional buyer,” as such term is defined under Rule 144A of the 1933 Act, will not be able to receive Fund Securities that are restricted securities eligible for resale under Rule 144A.

Creations and redemptions must be made through a firm that is either a member of the Continuous Net Settlement System of the National Securities Clearing Corporation or a DTC participant and has executed an agreement with the Distributor with respect to creations and redemptions of Creation Unit aggregations. Information about the procedures regarding creation and redemption of Creation Units (including the cut-off times for receipt of creation and redemption orders) is included in the Funds’ SAI.

Because new shares may be created and issued on an ongoing basis, at any point during the life of a Fund a “distribution,” as such term is used in the 1933 Act, may be occurring. Broker-dealers and other persons are cautioned that some activities on their part may, depending on the circumstances, result in their being deemed participants in a distribution in a manner that could render them statutory underwriters and subject to the prospectus delivery and liability provisions of the 1933 Act. Any determination of whether one is an underwriter must take into account all the relevant facts and circumstances of each particular case.

Broker-dealers should also note that dealers who are not “underwriters” but are participating in a distribution (as contrasted to ordinary secondary transactions), and thus dealing with shares that are part of an “unsold allotment” within the meaning of Section 4(3)(C) of the 1933 Act, would be unable to take advantage of the prospectus delivery exemption provided by Section 4(3) of the 1933 Act. For delivery of prospectuses to exchange members, the prospectus delivery mechanism of Rule 153 under the 1933 Act is available only with respect to transactions on a national securities exchange.

Costs Associated with Creations and Redemptions. Authorized Participants are charged standard creation and redemption transaction fees to offset transfer and other transaction costs associated with the issuance and redemption of Creation Units. The standard creation and redemption transaction fees are set forth in the table below. The standard creation transaction fee is charged to the Authorized Participant on the day such Authorized Participant creates a Creation Unit, and is the same regardless of the number of Creation Units purchased by the Authorized Participant on the applicable business day. Similarly, the standard redemption transaction fee is charged to the Authorized Participant on the day such Authorized Participant redeems a Creation Unit, and is the same regardless of the number of Creation Units redeemed by the Authorized Participant on the applicable business day. Creations and redemptions for cash (when cash creations and redemptions (in whole or in part) are available or specified) are also subject to an additional charge (up to the maximum amounts shown in the table below). This charge is intended to compensate for brokerage, tax, foreign exchange, execution, market impact and other costs and expenses related to cash transactions. Investors who use the services of a broker or other financial intermediary may pay fees for such services.

The following table shows, as of September 30, 2011, the approximate value of one Creation Unit, standard fees and maximum additional charges for creations and redemptions (as described above):

Householding. Householding is an option available to certain Fund investors. Householding is a method of delivery, based on the preference of the individual investor, in which a single copy of certain shareholder documents can be delivered to investors who share the same address, even if their accounts are registered under different names. Please contact your broker-dealer if you are interested in enrolling in householding and receiving a single copy of prospectuses and other shareholder documents, or if you are currently enrolled in householding and wish to change your householding status.

Distribution

The Distributor distributes Creation Units for each Fund on an agency basis. The Distributor does not maintain a secondary market in shares of the Funds. The Distributor has no role in determining the policies of any Fund or the securities that are purchased or sold by any Fund. The Distributor’s principal address is One Freedom Valley Drive, Oaks, PA 19456.

In addition, BFA or its Affiliates make payments to broker-dealers, banks or other financial intermediaries (together, “intermediaries”) related to marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems, or their making shares of the Funds and certain other iShares funds available to their customers. Such payments, which may be significant to the intermediary, are not made by the Funds. Rather, such payments are made by BFA or its Affiliates from their own resources, which come directly or indirectly in part from fees paid by the iShares funds complex. Payments of this type are sometimes referred to as revenue-sharing payments. A financial intermediary may make decisions about which investment options it recommends or makes available, or the level of services provided, to its customers based on the revenue-sharing payments it is eligible to receive. Therefore, such payments to an intermediary create conflicts of interest between the intermediary and its customers and may cause the intermediary to recommend the Funds or other iShares funds over another investment. More information regarding these payments is contained in the Funds’ SAI. Please contact your salesperson or other investment professional for more information regarding any such payments his or her firm may receive from BFA or its Affiliates.

Financial Highlights

The financial highlights table is intended to help investors understand each Fund’s financial performance since inception. Certain information reflects financial results for a single share of each Fund. The total returns in the table represent the rate that an investor would have earned (or lost) on an investment in each Fund, assuming reinvestment of all dividends and distributions. This information has been audited by PricewaterhouseCoopers LLP, whose report is included, along with each Fund’s financial statements, in each Fund’s Annual Report (available upon request).

Supplemental Information

I. Premium/Discount Information

Each table that follows presents information about the differences between the daily market price on secondary markets for shares of a Fund and the Fund’s NAV. NAV is the price at which each Fund issues and redeems shares. It is calculated in accordance with the standard formula for valuing mutual fund shares. The price used to calculate market returns (“Market Price”) of each Fund generally is determined using the midpoint between the highest bid and the lowest offer on the primary securities exchange on which shares of such Fund are listed for trading, as of the time that each Fund’s NAV is calculated. Each Fund’s Market Price may be at, above or below its NAV. The NAV of each Fund will fluctuate with changes in the value of its portfolio holdings. The Market Price of each Fund will fluctuate in accordance with changes in its NAV, as well as market supply and demand.

Premiums or discounts are the differences (expressed as a percentage) between the NAV and Market Price of a Fund on a given day, generally at the time the NAV is calculated. A premium is the amount that a Fund is trading above the reported NAV, expressed as a percentage of the NAV. A discount is the amount that a Fund is trading below the reported NAV, expressed as a percentage of the NAV.

The following information shows the frequency of distributions of premiums and discounts for each Fund for each full calendar quarter of 2010 through September 30, 2011.

Each line in the table shows the number of trading days in which each Fund traded within the premium/discount range indicated. The number of trading days in each premium/discount range is also shown as a percentage of the total number of trading days in a period covered by the table. All data presented here represents past performance, which cannot be used to predict future results.

II. Total Return Information

The tables that follow present information about the total returns of each Fund and the Underlying Index as of the fiscal year ended July 31, 2011.

“Average Annual Total Returns” represent the average annual change in value of an investment over the periods indicated. “Cumulative Total Returns” represent the total change in value of an investment over the periods indicated.

Each Fund’s NAV is the value of one share of such Fund as calculated in accordance with the standard formula for valuing mutual fund shares. The NAV return is based on the NAV of each Fund and the market return is based on the Market Price of each Fund. Market Price is determined by using the midpoint between the highest bid and the lowest offer on the primary stock exchange on which shares of each Fund are listed for trading, as of the time that such Fund’s NAV is calculated. Since shares of each Fund did not trade in the secondary market until after each Fund’s inception, for the period from inception to the first day of secondary market trading in shares of each Fund, the NAV of each Fund is used as a proxy for the Market Price to calculate market returns. Market and NAV returns assume that dividends and capital gain distributions have been reinvested in each Fund at Market Price and NAV, respectively.

An index is a statistical composite that tracks a specified financial market or sector. Unlike each Fund, the Underlying Index does not actually hold a portfolio of securities and therefore does not incur the expenses incurred by each Fund. These expenses negatively impact the performance of each Fund. Also, market returns do not include brokerage commissions that may be payable on secondary market transactions. If brokerage commissions were included, market returns would be lower. The returns shown in the following tables do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption or sale of Fund shares. The investment return and principal value of shares of each Fund will vary with changes in market conditions. Shares of each Fund may be worth more or less than their original cost when they are redeemed or sold in the market. Each Fund’s past performance is no guarantee of future results.

General Description of the Trust and its Funds

The Trust currently consists of more than 190 investment series or portfolios. The Trust was organized as a Delaware statutory trust on December 16, 1999 and is authorized to have multiple series or portfolios. The Trust is an open-end management investment company registered with the Securities and Exchange Commission (the “SEC”) under the Investment Company Act of 1940, as amended (the “1940 Act”). The offering of the Trust’s shares is registered under the Securities Act of 1933, as amended (the “1933 Act”). This SAI relates to the following Funds:

  • iShares FTSE China 25 Index Fund1
  • iShares FTSE China (HK Listed) Index Fund
  • iShares FTSE Developed Small Cap ex-North America Index Fund
  • iShares MSCI ACWI ex US Consumer Discretionary Sector Index Fund

  • iShares S&P North American Natural Resources Sector Index Fund
  • iShares S&P North American Technology Sector Index Fund
  • iShares S&P North American Technology-Multimedia Networking Index Fund
  • iShares S&P North American Technology-Software Index Fund

The investment objective of each Fund is to seek investment results that correspond generally to the price and yield performance, before fees and expenses, of a specified benchmark index (each, an “Underlying Index”) representing publicly-traded equity securities of issuers in a particular broad market, market segment, market sector or group of industries. Each

Fund is managed by BlackRock Fund Advisors (“BFA” or the “Investment Adviser”), a wholly-owned subsidiary of BTC, which in turn is indirectly wholly-owned by BlackRock, Inc.

Each Fund offers and issues shares at their net asset value per share (“NAV”) only in aggregations of a specified number of shares (“Creation Unit”), generally in exchange for a designated portfolio of securities (including any portion of such securities for which cash may be substituted) included in its Underlying Index (the “Deposit Securities”), together with the deposit of a specified cash payment (the “Cash Component”). The shares described in the applicable Prospectus and in this SAI are listed for trading on national securities exchanges (a “Listing Exchange”) such as The NASDAQ Stock Market (“NASDAQ”) or NYSE Arca, Inc. (“NYSE Arca”). Shares trade in the secondary market and elsewhere at market prices that may be at, above or below NAV. Shares are redeemable only in Creation Units, and, generally, in exchange for portfolio securities and a Cash Component. Creation Units typically are a specified number of shares, generally ranging from 50,000 to 100,000 or multiples thereof.


1 On December 16, 2010, the name of the Fund changed from the iShares FTSE/Xinhua China 25 Index Fund to the iShares FTSE China 25 Index Fund to reflect a change in the name of the Fund’s Underlying Index from FTSE/Xinhua China 25 Index to FTSE China 25 Index.
2 On October 15, 2010, the name of the Fund changed from the iShares S&P North American Technology-Semiconductors Index Fund to the iShares PHLX SOX Semiconductor Sector Index Fund to reflect a change in the Fund’s Index Provider from Standard & Poors Financial Services LLC to The NASDAQ OMX Group, Inc. (“NASDAQ OMX”) and a change in the Fund’s Underlying Index from S&P North American Technology-Semiconductors Index to PHLX Semiconductor Sector Index.

The Trust reserves the right to permit or require that creations and redemptions of shares are effected fully or partially in cash. Shares may be issued in advance of receipt of Deposit Securities, subject to various conditions, including a requirement to maintain with the Trust a cash deposit equal to at least 105% and up to 115%, which percentage BFA may change from time to time, of the market value of the omitted Deposit Securities. See the Creation and Redemption of Creation Units section of this SAI. Transaction fees associated with creations or redemptions that include a cash portion may be higher than the transaction fees associated with in-kind creations or redemptions. In all cases, conditions and fees will be limited in accordance with the requirements of SEC rules and regulations applicable to management investment companies offering redeemable securities.

Exchange Listing and Trading

A discussion of exchange listing and trading matters associated with an investment in each Fund is contained in the Shareholder Information section of each Fund’s Prospectus. The discussion below supplements, and should be read in conjunction with, that section of the applicable Prospectus.

Shares of each Fund are listed for trading, and trade throughout the day, on the applicable Listing Exchange and other secondary markets. Shares of certain Funds may also be listed on certain non-U.S. exchanges. There can be no assurance that the requirements of the Listing Exchange necessary to maintain the listing of shares of any Fund will continue to be met. The Listing Exchange may, but is not required to, remove the shares of a Fund from listing if (i) following the initial 12-month period beginning upon the commencement of trading of Fund shares, there are fewer than 50 beneficial owners of shares of the Fund for 30 or more consecutive trading days, (ii) the value of the Underlying Index on which the Fund is based is no longer calculated or available, (iii) the “indicative optimized portfolio value” (“IOPV”) of the Fund is no longer calculated or available, or (iv) any other event shall occur or condition shall exist that, in the opinion of the Listing Exchange, makes further dealings on the Listing Exchange inadvisable. The Listing Exchange will also remove shares of a Fund from listing and trading upon termination of the Fund.

As in the case of other publicly-traded securities, when you buy or sell shares through a broker you will incur a brokerage commission determined by that broker.

In order to provide additional information regarding the indicative value of shares of the Funds, the Listing Exchange or a market data vendor disseminates information every 15 seconds through the facilities of the Consolidated Tape Association, or through other widely disseminated means, an updated IOPV for the Funds as calculated by an information provider or market data vendor. The Trust is not involved in or responsible for any aspect of the calculation or dissemination of the IOPVs and makes no representation or warranty as to the accuracy of the IOPVs.

An IOPV has an equity securities component and a cash component. The equity securities values included in an IOPV are the values of the Deposit Securities for a Fund. While the IOPV reflects the current market value of the Deposit Securities required to be deposited in connection with the purchase of a Creation Unit, it does not necessarily reflect the precise composition of the current portfolio of securities held by the Fund at a particular point in time because the current portfolio of the Fund may include securities that are not a part of the current Deposit Securities. Therefore, a Fund’s IOPV disseminated during the Listing Exchange trading hours should not be viewed as a real-time update of the Fund’s NAV, which is calculated only once a day.

The cash component included in an IOPV consists of estimated accrued interest, dividends and other income, less expenses. If applicable, each IOPV also reflects changes in currency exchange rates between the U.S. dollar and the applicable currency.

The Trust reserves the right to adjust the share prices of the Funds in the future to maintain convenient trading ranges for investors. Any adjustments would be accomplished through stock splits or reverse stock splits, which would have no effect on the net assets of the Funds or an investor’s equity interest in the Funds.

Investment Strategies and Risks

Each Fund seeks to achieve its objective by investing primarily in securities that comprise its relevant Underlying Index and through transactions that provide substantially similar exposure to securities in the Underlying Index. Each Fund operates as an index fund and will not be actively managed. Adverse performance of a security in a Fund’s portfolio will ordinarily not result in the elimination of the security from a Fund’s portfolio.

Each Fund engages in representative sampling, which is investing in a sample of securities selected by BFA to have a collective investment profile similar to that of the Fund’s Underlying Index. Securities selected have aggregate investment characteristics (based on market capitalization and industry weightings), fundamental characteristics (such as return variability, earnings valuation and yield) and liquidity measures similar to those of the Underlying Index. Funds that use representative sampling generally do not hold all of the securities that are in their relevant Underlying Indexes.

Currency Transactions. The Funds do not expect to engage in currency transactions for the purpose of hedging against declines in the value of the Funds’ assets that are denominated in a non-U.S. currency. A Fund may enter into non-U.S. currency forward and non-U.S. currency futures contracts to facilitate local securities settlements or to protect against currency exposure in connection with its distributions to shareholders, but may not enter into such contracts for speculative purposes.

A forward currency contract is an obligation to purchase or sell a specific currency at a future date, which may be any fixed number of days from the date of the contract agreed upon by the parties, at a price set at the time of the contract. A currency futures contract is a contract involving an obligation to deliver or acquire the specified amount of a specific currency, at a specified price and at a specified future time. Currency futures contracts may be settled on a net cash payment basis rather than by the sale and delivery of the underlying currency. To the extent required by law, liquid assets committed to futures contracts will be maintained.

Foreign exchange transactions involve a significant degree of risk and the markets in which foreign exchange transactions are effected are highly volatile, highly specialized and highly technical. Significant changes, including changes in liquidity and prices, can occur in such markets within very short periods of time, often within minutes. Foreign exchange trading risks include, but are not limited to, exchange rate risk, counterparty risk, maturity gap, interest rate risk, and potential interference by foreign governments through regulation of local exchange markets, foreign investment or particular transactions in non-U.S. currency. If BFA utilizes foreign exchange transactions at an inappropriate time or judges market conditions, trends or correlations incorrectly, foreign exchange transactions may not serve their intended purpose of improving the correlation of a Fund’s return with the performance of its Underlying Index and may lower the Fund’s return. Each Fund could experience losses if the value of its currency forwards, options and futures positions were poorly correlated with its other investments or if it could not close out its positions because of an illiquid market. In addition, a Fund could incur transaction costs, including trading commissions, in connection with certain non-U.S. currency transactions.

With respect to 75% of a Fund’s total assets, a “diversified” fund is limited by the 1940 Act such that it does not invest more than 5% of its total assets in securities of any one issuer and does not acquire more than 10% of the outstanding voting securities of any one issuer (excluding cash and cash items, government securities, and securities of other investment companies). The remaining 25% of the fund’s total assets may be invested in any manner.

A “non-diversified” fund is a fund that is not limited by the 1940 Act with regard to the percentage of its assets that may be invested in the securities of a single issuer. The securities of a particular issuer (or securities of issuers in particular industries) may dominate the underlying index of such a fund and, consequently, the fund’s investment portfolio. This may adversely affect the fund’s performance or subject the fund’s shares to greater price volatility than that experienced by more diversified investment companies.

Each Fund (whether diversified or non-diversified) intends to maintain the required level of diversification and otherwise conduct its operations so as to qualify as a Regulated Investment Company (“RIC”) for purposes of the U.S. Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”), and to relieve the Fund of any liability for U.S. federal income tax to the extent that its earnings are distributed to shareholders, provided that the Fund satisfies a minimum distribution requirement. Compliance with the diversification requirements of the Internal Revenue Code may limit the investment flexibility of certain Funds and may make it less likely that the Funds will meet their respective investment objectives.

Futures and Options. Futures contracts and options may be used by a Fund to simulate investment in its Underlying Index, to facilitate trading or to reduce transaction costs. Each Fund may enter into futures contracts and options that are traded on a U.S. or non-U.S. exchange. No Fund will use futures or options for speculative purposes. Each Fund intends to use futures and options in accordance with Rule 4.5 of the Commodity Exchange Act (“CEA”). The Trust, on behalf of each Fund, has claimed an exclusion from the definition of the term “commodity pool operator” in accordance with Rule 4.5 so that a Fund is not subject to registration or regulation as a commodity pool operator under the CEA. On February 11, 2011, however, the Commodity Futures Trading Commission (“CFTC”) proposed certain regulatory changes that would subject registered investment companies to regulation by the CFTC if a fund invests more than a prescribed level of its liquidation value in futures and certain other instruments, or if the fund markets itself as providing investment exposure to such instruments. If these regulatory changes are ultimately adopted by the CFTC, a Fund may be subject to the CFTC registration requirements, and the disclosure and operations of each Fund would need to comply with all applicable regulations governing commodity pools. Compliance with these additional registration and regulatory requirements would increase Fund expenses. BFA may also be subject to CFTC regulation if a Fund is deemed to be a commodity pool. Other potentially adverse regulatory initiatives could also develop.

Futures contracts provide for the future sale by one party and purchase by another party of a specified amount of a specific instrument or index at a specified future time and at a specified price. Stock index contracts are based on investments that reflect the market value of common stock of the firms included in the investments. Each Fund may enter into futures contracts to purchase securities indexes when BFA anticipates purchasing the underlying securities and believes prices will rise before the purchase will be made. To the extent required by law, liquid assets committed to futures contracts will be maintained.

A call option gives a holder the right to purchase a specific security at a specified price (“exercise price”) within a specified period of time. A put option gives a holder the right to sell a specific security at a specified exercise price within a specified period of time. The initial purchaser of a call option pays the “writer” a premium, which is paid at the time of purchase and is retained by the writer whether or not such option is exercised. Each Fund may purchase put options to hedge its portfolio against the risk of a decline in the market value of securities held and may purchase call options to hedge against an increase in the price of securities it is committed to purchase. Each Fund may write put and call options along with a long position in options to increase its ability to hedge against a change in the market value of the securities it holds or is committed to purchase. Investments in futures contracts and other investments that contain leverage may require a Fund to maintain liquid assets. Generally, a Fund maintains an amount of liquid assets equal to its obligations relative to the position involved, adjusted daily on a marked-to-market basis. With respect to futures contracts that are contractually required to “cash-settle,” a Fund maintains liquid assets in an amount at least equal to a Fund’s daily marked-to-market obligation (i.e., a Fund’s daily net liability, if any), rather than the contracts’ notional value (i.e., the value of the underlying asset). By maintaining assets equal to its net obligation under cash-settled futures contracts, the Fund may employ leverage to a greater extent than if a Fund set aside assets equal to the futures contracts’ full notional value. Each Fund bases its asset maintenance policies on methods permitted by the staff of the SEC and may modify these policies in the future to comply with any changes in the guidance articulated from time to time by the SEC or its staff.

Illiquid Securities. Each Fund may invest up to an aggregate amount of 15% of its net assets in illiquid securities (calculated at the time of investment). Illiquid securities include securities subject to contractual or other restrictions on resale and other instruments that lack readily available markets.

Lending Portfolio Securities. Each Fund may lend portfolio securities to certain creditworthy borrowers, including borrowers affiliated with BFA. The borrowers provide collateral that is maintained in an amount at least equal to the current market value of the securities loaned. No securities loan shall be made on behalf of a Fund if, as a result, the aggregate value of all securities loans of the particular Fund exceeds one-third of the value of such Fund’s total assets (including the value of the collateral received). A Fund may terminate a loan at any time and obtain the return of the securities loaned. Each Fund receives the value of any interest or cash or non-cash distributions paid on the loaned securities.

With respect to loans that are collateralized by cash, the borrower will be entitled to receive a fee based on the amount of cash collateral. The Funds are compensated by the difference between the amount earned on the reinvestment of cash collateral and the fee paid to the borrower. In the case of collateral other than cash, a Fund is compensated by a fee paid by the borrower equal to a percentage of the market value of the loaned securities. Any cash collateral may be reinvested in certain short-term instruments either directly on behalf of each lending Fund or through one or more joint accounts or

money market funds, including those affiliated with BFA; such reinvestments are subject to investment risk. BFA may receive compensation for these investments.

Securities lending involves exposure to certain risks, including operational risk (i.e., the risk of losses resulting from problems in the settlement and accounting process), “gap” risk (i.e., the risk of a mismatch between the return on cash collateral reinvestments and the fees each Fund has agreed to pay a borrower), and credit, legal, counterparty and market risk. If a securities lending counterparty were to default, a Fund would be subject to the risk of a possible delay in receiving collateral or in recovering the loaned securities, or to a possible loss of rights in the collateral. In the event a borrower does not return a Fund’s securities as agreed, the Fund may experience losses if the proceeds received from liquidating the collateral do not at least equal the value of the loaned security at the time the collateral is liquidated, plus the transaction costs incurred in purchasing replacement securities. This event could trigger adverse tax consequences for the Funds. Substitute payments for dividends received by a Fund for securities loaned out by the Fund will not be considered qualified dividend income. The Fund takes the tax effects of this difference into account in its securities lending program.

Each Fund pays a portion of the interest or fees earned from securities lending to a borrower as described above and to a securities lending agent who administers the lending program in accordance with guidelines approved by the Trust’s Board of Trustees (the “Board” or the “Trustees”). To the extent that the Funds engage in securities lending, BTC acts as securities lending agent for the Funds, subject to the overall supervision of BFA. BTC receives a portion of the revenues generated by securities lending activities as compensation for its services.

Non-U.S. Securities. Each Fund may purchase publicly-traded common stocks of non-U.S. issuers. To the extent a Fund invests in stocks of non-U.S. issuers, certain of the Fund’s investments in such stocks may be in the form of American Depositary Receipts (“ADRs”), Global Depositary Receipts (“GDRs”) and European Depositary Receipts (“EDRs”) (collectively, “Depositary Receipts”). Depositary Receipts are receipts, typically issued by a bank or trust issuer, which evidence ownership of underlying securities issued by a non-U.S. issuer. For ADRs, the depository is typically a U.S. financial institution and the underlying securities are issued by a non-U.S. issuer. For other forms of Depositary Receipts, the depository may be a non-U.S. or a U.S. entity, and the underlying securities may be issued by a non-U.S. or a U.S. issuer. Depositary Receipts are not necessarily denominated in the same currency as their underlying securities. Generally, ADRs, issued in registered form, are designed for use in the U.S. securities markets, and EDRs, issued in bearer form, are designed for use in European securities markets. GDRs are tradable both in the United States and in Europe and are designed for use throughout the world.

The Funds will not invest in any unlisted Depositary Receipt or any Depositary Receipt that BFA deems illiquid at the time of purchase or for which pricing information is not readily available. In general, Depositary Receipts must be sponsored, but a Fund may invest in unsponsored Depositary Receipts under certain limited circumstances. The issuers of unsponsored Depositary Receipts are not obligated to disclose material information in the United States. Therefore, there may be less information available regarding such issuers and there may be no correlation between available information and the market value of the Depositary Receipts.

Investing in the securities of non-U.S. issuers involves special risks and considerations not typically associated with investing in U.S. issuers. These include differences in accounting, auditing and financial reporting standards, the possibility of expropriation or confiscatory taxation, adverse changes in investment or exchange control regulations, political instability which could affect U.S. investments in non-U.S. countries, and potential restrictions on the flow of international capital. Non-U.S. issuers may be subject to less governmental regulation than U.S. issuers. Moreover, individual non-U.S. economies may differ favorably or unfavorably from the U.S. economy in such respects as growth of gross domestic product, rate of inflation, capital reinvestment, resource self-sufficiency and balance of payment positions.

Options on Futures Contracts. An option on a futures contract, as contrasted with the direct investment in such a contract, gives the purchaser the right, in return for the premium paid, to assume a position in the underlying futures contract at a specified exercise price at any time prior to the expiration date of the option. Upon exercise of an option, the delivery of the futures position by the writer of the option to the holder of the option will be accompanied by delivery of the accumulated balance in the writer’s futures margin account that represents the amount by which the market price of the futures contract exceeds (in the case of a call) or is less than (in the case of a put) the exercise price of the option on the futures contract. The potential for loss related to the purchase of an option on a futures contract is limited to the premium paid for the option plus transaction costs. Because the value of the option is fixed at the point of sale, there are no daily cash payments by the purchaser to reflect changes in the value of the underlying contract; however, the value of the option changes daily and that

change would be reflected in the NAV of each Fund. The potential for loss related to writing call options is unlimited. The potential for loss related to writing put options is limited to the agreed upon price per share, also known as the “strike price,” less the premium received from writing the put.

Each Fund may purchase and write put and call options on futures contracts that are traded on an exchange as a hedge against changes in value of its portfolio securities, or in anticipation of the purchase of securities, and may enter into closing transactions with respect to such options to terminate existing positions. There is no guarantee that such closing transactions can be effected.

Upon entering into a futures contract, a Fund will be required to deposit with the broker an amount of cash or cash equivalents known as “initial margin,” which is in the nature of a performance bond or good faith deposit on the contract and is returned to a Fund upon termination of the futures contract, assuming all contractual obligations have been satisfied. Subsequent payments, known as “variation margin,” to and from the broker will be made daily as the price of the index underlying the futures contract fluctuates, making the long and short positions in the futures contract more or less valuable, a process known as “marking-to-market.” At any time prior to the expiration of a futures contract, a Fund may elect to close the position by taking an opposite position, which will operate to terminate a Fund’s existing position in the contract.

Repurchase Agreements. A repurchase agreement is an instrument under which the purchaser (i.e., a Fund) acquires the security and the seller agrees, at the time of the sale, to repurchase the security at a mutually agreed upon time and price, thereby determining the yield during the purchaser’s holding period. Repurchase agreements may be construed to be collateralized loans by the purchaser to the seller secured by the securities transferred to the purchaser. If a repurchase agreement is construed to be a collateralized loan, the underlying securities will not be considered to be owned by each Fund but only to constitute collateral for the seller’s obligation to pay the repurchase price, and, in the event of a default by the seller, each Fund may suffer time delays and incur costs or losses in connection with the disposition of the collateral.

In any repurchase transaction, the collateral for a repurchase agreement may include: (i) cash items; (ii) obligations issued by the U.S. government or its agencies or instrumentalities; or (iii) obligations that, at the time the repurchase agreement is entered into, are rated in the highest rating category generally by at least two nationally recognized statistical rating organizations (“NRSRO”), or, if unrated, determined to be of comparable quality by BFA. Collateral, however, is not limited to the foregoing and may include, for example, obligations rated below the highest category by NRSROs. Collateral for a repurchase agreement may also include securities that a Fund could not hold directly without the repurchase obligation. Irrespective of the type of collateral underlying the repurchase agreement, in the case of a repurchase agreement entered into by a non-money market fund, the repurchase obligation of a seller must be of comparable credit quality to securities which are rated in one of the two highest rating categories by any NRSRO.

Repurchase agreements pose certain risks for a Fund that utilizes them. Such risks are not unique to the Funds, but are inherent in repurchase agreements. The Funds seek to minimize such risks, but because of the inherent legal uncertainties involved in repurchase agreements, such risks cannot be eliminated. Lower quality collateral and collateral with longer maturities may be subject to greater price fluctuations than higher quality collateral and collateral with shorter maturities. If the repurchase agreement counterparty were to default, lower quality collateral may be more difficult to liquidate than higher quality collateral. Should the counterparty default and the amount of collateral not be sufficient to cover the counterparty’s repurchase obligation, the Fund would retain the status of an unsecured creditor of the counterparty (i.e., the position the Fund would normally be in if it were to hold, pursuant to its investment policies, other unsecured debt securities of the defaulting counterparty) with respect to the amount of the shortfall. As an unsecured creditor, a Fund would be at risk of losing some or all of the principal and income involved in the transaction.

Reverse Repurchase Agreements. Reverse repurchase agreements involve the sale of securities with an agreement to repurchase the securities at an agreed-upon price, date and interest payment and have the characteristics of borrowing. Generally, the effect of such transactions is that a Fund can recover all or most of the cash invested in the portfolio securities involved during the term of the reverse repurchase agreement, while in many cases the Fund is able to keep some of the interest income associated with those securities. Such transactions are advantageous only if a Fund has an opportunity to earn a rate of interest on the cash derived from these transactions that is greater than the interest cost of obtaining the same amount of cash. Opportunities to realize earnings from the use of the proceeds equal to or greater than the interest required to be paid may not always be available and a Fund intends to use the reverse repurchase technique only when BFA believes it

will be advantageous to the Fund. The use of reverse repurchase agreements may exaggerate any interim increase or decrease in the value of a Fund’s assets. A Fund’s exposure to reverse repurchase agreements will be covered by liquid assets having a value equal to or greater than such commitments.

Securities of Investment Companies. Each Fund may invest in the securities of other investment companies (including money market funds) and real estate investment trusts (“REITs”) to the extent allowed by law. Pursuant to the 1940 Act, a Fund’s investment in registered investment companies is limited to, subject to certain exceptions: (i) 3% of the total outstanding voting stock of any one investment company; (ii) 5% of the Fund’s total assets with respect to any one investment company; and (iii) 10% of the Fund’s total assets with respect to investment companies in the aggregate. To the extent allowed by law or regulation, each Fund may invest its assets in the securities of investment companies that are money market funds, including those advised by or otherwise affiliated with BFA, in excess of the limits discussed above. Other investment companies in which a Fund may invest can be expected to incur fees and expenses for operations, such as investment advisory and administration fees, which would be in addition to those incurred by the Fund.

Short-Term Instruments and Temporary Investments. Each Fund may invest in short-term instruments, including money market instruments, on an ongoing basis to provide liquidity or for other reasons. Money market instruments are generally short-term investments that may include but are not limited to: (i) shares of money market funds (including those advised by BFA or otherwise affiliated with BFA); (ii) obligations issued or guaranteed by the U.S. government, its agencies or instrumentalities (including government-sponsored enterprises); (iii) negotiable certificates of deposit (“CDs”), bankers’ acceptances, fixed-time deposits and other obligations of U.S. and non-U.S. banks (including non-U.S. branches) and similar institutions; (iv) commercial paper rated, at the date of purchase, “Prime-1” by Moody’s® Investors Service, Inc., “F-1” by Fitch Inc., or “A-1” by Standard & Poor’s® (a subsidiary of The McGraw-Hill Companies, Inc.) (“S&P®”), or if unrated, of comparable quality as determined by BFA; (v) non-convertible corporate debt securities (e.g., bonds and debentures) with remaining maturities at the date of purchase of not more than 397 days and that satisfy the rating requirements set forth in Rule 2a-7 under the 1940 Act; (vi) repurchase agreements; and (vii) short-term U.S. dollar-denominated obligations of non-U.S. banks (including U.S. branches) that, in the opinion of BFA, are of comparable quality to obligations of U.S. banks which may be purchased by a Fund. Any of these instruments may be purchased on a current or forward-settled basis. Time deposits are non-negotiable deposits maintained in banking institutions for specified periods of time at stated interest rates. Bankers’ acceptances are time drafts drawn on commercial banks by borrowers, usually in connection with international transactions.

Swap Agreements. Swap agreements are contracts between parties in which one party agrees to make periodic payments to the other party based on the change in market value or level of a specified rate, index or asset. In return, the other party agrees to make periodic payments to the first party based on the return of a different specified rate, index or asset. Swap agreements will usually be performed on a net basis, with a Fund receiving or paying only the net amount of the two payments. The net amount of the excess, if any, of a Fund’s obligations over its entitlements with respect to each swap is accrued on a daily basis and an amount of liquid assets having an aggregate value at least equal to the accrued excess will be maintained by the Fund.

The use of interest rate and index swaps is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio security transactions. These transactions generally do not involve the delivery of securities or other underlying assets or principal.

Tracking Stocks. A tracking stock is a separate class of common stock whose value is linked to a specific business unit or operating division within a larger company and is designed to “track” the performance of such business unit or division. The tracking stock may pay dividends to shareholders independent of the parent company. The parent company, rather than the business unit or division, generally is the issuer of tracking stock. However, holders of the tracking stock may not have the same rights as holders of the company’s common stock.

Future Developments. The Board may, in the future, authorize a Fund to invest in securities contracts and investments, other than those listed in this SAI and in the applicable Prospectuses, provided they are consistent with a Fund’s investment objective and do not violate any investment restrictions or policies.

General Considerations and Risks

A discussion of some of the principal risks associated with an investment in a Fund is contained in the applicable Prospectus.

An investment in a Fund should be made with an understanding that the value of the Fund’s portfolio securities may fluctuate in accordance with changes in the financial condition of the issuers of the portfolio securities, the value of stocks in general, and other factors that affect the market.

Commodities Investment Risk. Exposure to commodities markets may subject a Fund to greater volatility than investments in traditional securities. The commodities markets have experienced periods of extreme volatility. Similar future market conditions may result in rapid and substantial valuation increases or decreases in a Fund’s holdings.

The commodities markets may fluctuate widely based on a variety of factors. Movements in commodity investment prices are outside of a Fund’s control and may not be anticipated by Fund management. Price movements may be influenced by, among other things: governmental, agricultural, trade, fiscal, monetary and exchange control programs and policies; changing market and economic conditions; market liquidity; weather and climate conditions, including droughts and floods; livestock disease; changing supply and demand relationships and levels of domestic production and imported commodities; changes in storage costs; the availability of local, intrastate and interstate transportation systems; energy conservation; the success of exploration projects; changes in international balances of payments and trade; domestic and foreign rates of inflation; currency devaluations and revaluations; domestic and foreign political and economic events; domestic and foreign interest rates and/or investor expectations concerning interest rates; foreign currency/exchange rates; domestic and foreign governmental regulation and taxation; war, acts of terrorism and other political upheaval and conflicts; governmental expropriation; investment and trading activities of mutual funds, hedge funds and commodities funds; and changes in philosophies and emotions of market participants. The frequency and magnitude of such changes cannot be predicted.

The prices of commodities can also fluctuate widely due to supply and demand disruptions in major producing or consuming regions. Certain commodities or natural resources may be produced in a limited number of countries and may be controlled by a small number of producers or groups of producers. As a result, political, economic regulator and supply-related events in such countries could have a disproportionate impact on the prices of such commodities.

A decrease in the production of a physical commodity or a decrease in the volume of such commodity available for transportation, mining, processing, storage or distribution may adversely impact the financial performance of a commodity or commodity-related company that devotes a portion of its business to that commodity. Production declines and volume decreases could be caused by various factors, including catastrophic events affecting production, depletion of resources, labor difficulties, environmental proceedings, increased regulations, equipment failures and unexpected maintenance problems, import supply disruption, governmental expropriation, political upheaval or conflicts or increased competition from alternative energy sources or commodity prices. Agricultural commodities may be adversely affected by weather or other natural phenomena, such as drought, floods and pests.

A sustained decline in demand for such commodities could also adversely affect the financial performance of commodity-related companies. Factors that could lead to a decline in demand include economic recession or other adverse economic conditions, higher taxes on commodities or increased governmental regulations, increases in fuel economy, consumer shifts to the use of alternative commodities or fuel sources, changes in commodity prices, or weather.

The commodity markets are subject to temporary distortions and other disruptions due to, among other factors, lack of liquidity, the participation of speculators, and government regulation and other actions. U.S. futures exchanges and some foreign exchanges limit the amount of fluctuation in futures contract prices which may occur in a single business day (generally referred to as “daily price fluctuation limits”). The maximum or minimum price of a contract as a result of these limits is referred to as a “limit price.” If the limit price has been reached in a particular contract, no trades may be made beyond the limit price. Limit prices have the effect of precluding trading in a particular contract or forcing the liquidation of contracts at disadvantageous times or prices.

Custody Risk. Custody risk refers to the risks inherent in the process of clearing and settling trades and to the holding of securities by local banks, agents and depositories. Low trading volumes and volatile prices in less developed markets make trades harder to complete and settle, and governments or trade groups may compel local agents to hold securities in designated depositories that may not be subject to independent evaluation. Local agents are held only to the standards of care of their local markets. The less developed a country’s securities market is, the greater the likelihood of custody problems.

Dividend Risk. There is no guarantee that the issuer of the stocks held by a Fund will declare dividends in the future or that if declared, they will either remain at current levels or increase over time.

Risks of Derivatives. A derivative is a financial contract, the value of which depends on, or is derived from, the value of an underlying asset such as a security or an index. A Fund may invest in stock index futures contracts and other derivatives. Compared to conventional securities, derivatives can be more sensitive to changes in interest rates or to sudden fluctuations in market prices and thus a Fund’s losses may be greater if it invests in derivatives than if it invests only in conventional securities. Derivatives are also subject to counterparty risk, which is the risk that the other party in the transaction will not fulfill its contractual obligations.

Risks of Equity Securities. An investment in a Fund should be made with an understanding of the risks inherent in an investment in equity securities, including the risk that the financial condition of issuers may become impaired or that the general condition of stock markets may deteriorate (either of which may cause a decrease in the value of the portfolio securities and thus in the value of shares of a Fund). Common stocks are susceptible to general stock market fluctuations and to increases and decreases in value as market confidence and perceptions of their issuers change. These investor perceptions are based on various and unpredictable factors, including expectations regarding government, economic, monetary and fiscal policies, inflation and interest rates, economic expansion or contraction, and global or regional political, economic or banking crises. Holders of common stocks incur more risks than holders of preferred stocks and debt obligations because common stockholders generally have rights to receive payments from stock issuers that are inferior to the rights of creditors, or holders of debt obligations or preferred stocks. Further, unlike debt securities, which typically have a stated principal amount payable at maturity (the value of which, however, is subject to market fluctuations prior to maturity), or preferred stocks, which typically have a liquidation preference and which may have stated optional or mandatory redemption provisions, common stocks have neither a fixed principal amount nor a maturity.

Although most of the securities in each Underlying Index are listed on a national securities exchange, the principal trading market for some of the securities may be in the over-the-counter market. The existence of a liquid trading market for certain securities may depend on whether dealers will make a market in such securities. There can be no assurance that a market will be made or maintained or that any such market will be or remain liquid. The price at which securities may be sold and the value of a Fund’s shares will be adversely affected if trading markets for the Fund’s portfolio securities are limited or absent, or if bid/ask spreads are wide.

Risks of Futures and Options Transactions. There are several risks accompanying the utilization of futures contracts and options on futures contracts. First, a position in futures contracts and options on futures contracts may be closed only on the exchange on which the contract was made (or a linked exchange). While each Fund plans to utilize futures contracts only if an active market exists for such contracts, there is no guarantee that a liquid market will exist for the contract at a specified time. Furthermore, because, by definition, futures contracts project price levels in the future and not current levels of valuation, market circumstances may result in a discrepancy between the price of the stock index future and the movement in a Fund’s Underlying Index. In the event of adverse price movements, a Fund would continue to be required to make daily cash payments to maintain its required margin. In such situations, if a Fund has insufficient cash, it may have to sell portfolio securities to meet daily margin requirements at a time when it may be disadvantageous to do so. In addition, a Fund may be required to deliver the instruments underlying the future contracts it has sold.

The risk of loss in trading futures contracts or uncovered call options in some strategies (e.g., selling uncovered stock index futures contracts) is potentially unlimited. The Funds do not plan to use futures and options contracts in this way. The risk of a futures position may still be large as traditionally measured due to the low margin deposits required. In many cases, a relatively small price movement in a futures contract may result in immediate and substantial loss or gain to the investor relative to the size of a required margin deposit. The Funds, however, intend to utilize futures and options contracts in a manner designed to limit their risk exposure to levels comparable to a direct investment in the types of stocks in which they invest.

Utilization of futures and options on futures by a Fund involves the risk of imperfect or even negative correlation to its Underlying Index if the index underlying the futures contract differs from the Underlying Index. There is also the risk of loss by the Fund of margin deposits in the event of bankruptcy of a broker with whom a Fund has an open position in the futures contract or option. The purchase of put or call options will be based upon predictions by BFA as to anticipated trends, which predictions could prove to be incorrect.

Because the futures market generally imposes less burdensome margin requirements than the securities market, an increased amount of participation by speculators in the futures market could result in price fluctuations. Certain financial futures exchanges limit the amount of fluctuation permitted in futures contract prices during a single trading day. The daily

limit establishes the maximum amount by which the price of a futures contract may vary either up or down from the previous day’s settlement price at the end of a trading session. Once the daily limit has been reached in a particular type of contract, no trades may be made on that day at a price beyond that limit. It is possible that futures contract prices could move to the daily limit for several consecutive trading days with little or no trading, thereby preventing prompt liquidation of futures positions and subjecting each Fund to substantial losses. In the event of adverse price movements, each Fund would be required to make daily cash payments of variation margin.

Risks of Investing in Asia. Investments in securities of issuers in certain Asian countries involve risks not typically associated with investments in securities of issuers in more developed countries. Such heightened risks include, among others, expropriation and/or nationalization of assets, confiscatory taxation, political instability, including authoritarian and/or military involvement in governmental decision-making, armed conflict and social instability as a result of religious, ethnic and/or socio-economic unrest.

Certain Asian countries have democracies with relatively short histories, which may increase the risk of political instability. These countries have faced political and military unrest, and further unrest could present a risk to their local economies and securities markets. Indonesia and the Philippines have each experienced violence and terrorism, which has negatively impacted their economies. North and South Korea each have substantial military capabilities, and historical tensions between the two countries present the risk of war. Any outbreak of hostilities between the two countries could have a severe adverse effect on the South Korean economy and securities market. Increased political and social unrest in these geographic areas could adversely affect the performance of investments in this region.

Certain governments in this region administer prices on several basic goods, including fuel and electricity, within their respective countries. Certain governments may exercise substantial influence over many aspects of the private sector in their respective countries and may own or control many companies. Future government actions could have a significant effect on the economic conditions in this region, which in turn could have a negative impact on private sector companies. There is also the possibility of diplomatic developments adversely affecting investments in the region.

Corruption and the perceived lack of a rule of law in dealings with international companies in certain Asian countries may discourage foreign investment and could negatively impact the long-term growth of certain economies in this region. In addition, certain countries in the region are experiencing high unemployment and corruption, and have fragile banking sectors.

Some economies in this region are dependent on a range of commodities, including oil, natural gas and coal. Accordingly, they are strongly affected by international commodity prices and particularly vulnerable to any weakening in global demand for these products. The market for securities in this region may also be directly influenced by the flow of international capital, and by the economic and market conditions of neighboring countries. Adverse economic conditions or developments in neighboring countries may increase investors’ perception of the risk of investing in the region as a whole, which may adversely impact the market value of the securities issued by companies in the region.

Risks of Investing in Australasia. The economies of Australasia, which include Australia and New Zealand, are dependent on exports from the agricultural and mining sectors. This makes Australasian economies susceptible to fluctuations in the commodity markets. Australasian economies are also increasingly dependent on their growing service industries. Because the economies of Australasia are dependent on the economies of Asia, Europe and the United States as key trading partners and investors, reduction in spending by any of these trading partners on Australasian products and services, or negative changes in any of these economies, may cause an adverse impact on some or all of the Australasian economies. Additionally, Australia and New Zealand are located in a region that has historically been prone to natural disasters. Any natural disaster in the region could negatively impact the economies of Australia and New Zealand and affect the value of securities held by a Fund.

Risks of Investing in Brazil. Investment in securities of companies domiciled in Brazil involves a high degree of risk and special considerations not typically associated with investing in the U.S. securities markets. Such heightened risks include, among others, a high level of price volatility in the Brazilian equity and currency markets, chronic structural public sector deficits and disparities of wealth.

Brazil has historically experienced high rates of inflation and may continue to do so in the future. An increase in prices for commodities, the depreciation of the Brazilian currency (the real) and potential future governmental measures seeking to maintain the value of the real in relation to the U.S. dollar, may trigger increases in inflation in Brazil and may slow the rate of

growth of the Brazilian economy. Inflationary pressures also may limit the ability of certain Brazilian issuers to access foreign financial markets and may lead to further government intervention in the economy, including the introduction of government policies that may adversely affect the overall performance of the Brazilian economy, which in turn could adversely affect a Fund’s investments.

The Brazilian government has exercised, and continues to exercise, significant influence over the Brazilian economy, which may have significant effects on Brazilian companies and on market conditions and prices of Brazilian securities. The Brazilian economy has been characterized by frequent, and occasionally drastic, intervention by the Brazilian government. The Brazilian government has often changed monetary, taxation, credit, tariff and other policies to influence the core of Brazil’s economy. The Brazilian government’s actions to control inflation and affect other economic policies have involved, among others, the setting of wage and price controls, blocking access to bank accounts, fluctuation of the base interest rates, imposing exchange controls and limiting imports into Brazil. In the past, the Brazilian government has maintained domestic price controls, and no assurances can be given that price controls will not be re-imposed in the future.

Investments in Brazilian securities may be subject to certain restrictions on foreign investment. Brazilian law provides that whenever a serious imbalance in Brazil’s balance of payments exists or is anticipated, the Brazilian government may impose temporary restrictions on the remittance to foreign investors of the proceeds of their investment in Brazil and on the conversion of Brazilian currency into foreign currency. The likelihood of such restrictions may be affected by the extent of Brazil’s foreign currency reserves, the availability of sufficient foreign currency in the foreign exchange markets on the date a payment is due, the size of Brazil’s debt service burden relative to the economy as a whole and political constraints to which Brazil may be subject. There can be no assurance that the Brazilian government will not impose restrictions or restrictive exchange control policies in the future, which could have the effect of preventing or restricting access to foreign currency.

The market for Brazilian securities is directly influenced by the flow of international capital, and economic and market conditions of certain countries, especially other emerging market countries in Central and South America. Adverse economic conditions or developments in other emerging market countries have at times significantly affected the availability of credit in the Brazilian economy and resulted in considerable outflows of funds and declines in the amount of foreign currency invested in Brazil. Crisis in neighboring emerging market countries also may increase investors’ risk aversion, which may adversely impact the market value of the securities issued by Brazilian companies, including securities in which a Fund may invest.

Risks of Investing in Canada. The United States is Canada’s largest trading and investment partner, and the Canadian economy is significantly affected by developments in the U.S. economy. Since the implementation of the North American Free Trade Agreement (“NAFTA”) in 1994 among Canada, the United States and Mexico, total two-way merchandise trade between the United States and Canada has more than doubled. To further this relationship, the three NAFTA countries entered into The Security and Prosperity Partnership of North America in March 2005, which may further affect Canada’s dependency on the U.S. economy. Any downturn in U.S. or Mexican economic activity is likely to have an adverse impact on the Canadian economy. The Canadian economy is also dependent upon external trade with other key trading partners, specifically China and the United Kingdom. As a result, Canada is dependent on the economies of these other countries. In addition, Canada is a large supplier of natural resources (e.g., oil, natural gas and agricultural products). As a result, the Canadian economy is sensitive to fluctuations in certain commodity prices.

Risks of Investing in Central and South American Economies. The economies of certain countries in which a Fund invests are affected by the economies of other Central and South American countries, some of which have experienced high interest rates, economic volatility, inflation, currency devaluations, government defaults and high unemployment rates. In addition, commodities (such as oil, gas and minerals) represent a significant percentage of the region’s exports and many economies in this region are particularly sensitive to fluctuations in commodity prices. Adverse economic events in one country may have a significant adverse effect on some or all of the countries to which a Fund has exposure.

Risks of Investing in China. Investments in securities of companies domiciled in China involves a high degree of risk and special considerations not typically associated with investing in the U.S. securities markets. Such heightened risks include, among others, an authoritarian government, popular unrest associated with demands for improved political, economic and social conditions, the impact of regional conflict on the economy and hostile relations with neighboring countries.

Military conflicts, either in response to internal social unrest or conflicts with other countries, could disrupt economic development. The Chinese economy is vulnerable to the long-running disagreements with Hong Kong related to integration and religious and nationalist disputes with Tibet. China has a complex territorial dispute regarding the sovereignty of Taiwan that has included threats of invasion; Taiwan-based companies and individuals are significant investors in China. Military

conflict between China and Taiwan may adversely affect securities of Chinese issuers. In addition, China has strained international relations with Japan, India, Russia and other neighbors due to territorial disputes, historical animosities and other defense concerns. China could be affected by military events on the Korean peninsula or internal instability within North Korea. These situations may cause uncertainty in the Chinese market and may adversely affect performance of the Chinese economy.

The Chinese government has implemented significant economic reforms in order to liberalize trade policy, promote foreign investment in the economy, reduce government control of the economy and develop market mechanisms. But there can be no assurance that these reforms will continue or that they will be effective. Despite recent reform and privatizations of companies in certain sectors, the Chinese government still exercises substantial influence over many aspects of the private sector and may own or control many companies. The Chinese government continues to maintain a major role in economic policy making and investing in China involves risk of loss due to expropriation, nationalization, confiscation of assets and property or the imposition of restrictions on foreign investments and on repatriation of capital invested. In addition, there is less regulation and monitoring of Chinese securities markets and the activities of investors, brokers and other participants than in the United States. Accordingly, issuers of securities in China are not subject to the same degree of regulation as are U.S. issuers with respect to such matters as insider trading rules, tender offer regulation, stockholder proxy requirements and the requirements mandating timely and accurate disclosure of information. Stock markets in China are in the process of change and further development. This may lead to trading volatility, difficulty in the settlement and recording of transactions and difficulty in interpreting and applying the relevant regulation.

While the Chinese economy has grown rapidly in recent years, there is no assurance that this growth rate will be maintained. China may experience substantial rates of inflation or economic recessions, causing a negative effect on the economy and securities market. China’s economy is heavily dependent on export growth. Reduction in spending on Chinese products and services, institution of tariffs or other trade barriers or a downturn in any of the economies of China’s key trading partners may have an adverse impact on the securities of Chinese issuers.

The tax laws and regulations in the People’s Republic of China (“PRC”) are subject to change, including the issuance of authoritative guidance or enforcement, possibly with retroactive effect. The interpretation, applicability and enforcement of such laws by PRC tax authorities are not as consistent and transparent as those of more developed nations, and may vary over time and from region to region. The application and enforcement of PRC tax rules could have a significant adverse effect on a Fund and its investors, particularly in relation to capital gains withholding tax imposed upon non-residents.

Risks of Investing in Eastern Europe. Investing in the securities of Eastern European issuers is highly speculative and involves risks not usually associated with investing in the more developed markets of Western Europe. Political and economic reforms are too recent to establish a definite trend away from centrally planned economies and state-owned industries. In the past, some Eastern European governments have expropriated substantial amounts of private property, and many claims of the property owners have never been fully settled.

Many Eastern European countries continue to move towards market economies at different paces with appropriately different characteristics. Most Eastern European markets suffer from thin trading activity, dubious investor protections, and often a dearth of reliable corporate information. Information and transaction costs, differential taxes, and sometimes political or transfer risk give a comparative advantage to the domestic investor rather than the foreign investor. In addition, these markets are particularly sensitive to social, political, economic, and currency events in Russia and may suffer heavy losses as a result of their trading and investment links to the Russian economy and currency. Russia also may attempt to assert its influence in the region through economic or even military measures, as it did with Georgia in the summer of 2008. Eastern European economies may also be particularly susceptible to the international credit market due to their reliance on bank related inflows of capital. The recent global economic crisis restricted international credit supplies and several Eastern European economies faced significant credit and economic crises. Although some Eastern European economies are expanding again, major challenges are still present as a result of their continued dependence on the Western European zone for credit.

Risks of Investing in Emerging Markets Securities. Investments in emerging market countries may be subject to greater risks than investments in developed countries. These risks include: (i) less social, political, and economic stability; (ii) greater illiquidity and price volatility due to smaller or limited local capital markets for such securities, or low non-existent trading volumes; (iii) foreign exchanges and broker-dealers may be subject to less scrutiny and regulation by local authorities; (iv) local governments may decide to seize or confiscate securities held by foreign investors and/or local governments may

decide to suspend or limit an issuer’s ability to make dividend or interest payments; (v) local governments may limit or entirely restrict repatriation of invested capital, profits, and dividends; (vi) capital gains may be subject to local taxation, including on a retroactive basis; (vii) issuers facing restrictions on dollar or euro payments imposed by local governments may attempt to make dividend or interest payments to foreign investors in the local currency; (viii) investors may experience difficulty in enforcing legal claims related to the securities and/or local judges may favor the interests of the issuer over those of foreign investors; (ix) bankruptcy judgments may only be permitted to be paid in the local currency; (x) limited public information regarding the issuer may result in greater difficulty in determining market valuations of the securities, and (xi) lax financial reporting on a regular basis, substandard disclosure and differences in accounting standards may make it difficult to ascertain the financial health of an issuer.

Emerging market securities markets are typically marked by a high concentration of market capitalization and trading volume in a small number of issuers representing a limited number of industries, as well as a high concentration of ownership of such securities by a limited number of investors. In addition, brokerage and other costs associated with transactions in emerging markets securities markets can be higher, sometimes significantly, than similar costs incurred in securities markets in developed countries. Although some emerging markets have become more established and tend to issue securities of higher credit quality, the markets for securities in other emerging countries are in the earliest stages of their development, and these countries issue securities across the credit spectrum. Even the markets for relatively widely traded securities in emerging countries may not be able to absorb, without price disruptions, a significant increase in trading volume or trades of a size customarily undertaken by institutional investors in the securities markets of developed countries. The limited size of many of these securities markets can cause prices to be erratic for reasons apart from factors that affect the soundness and competitiveness of the securities issuers. For example, prices may be unduly influenced by traders who control large positions in these markets. Additionally, market making and arbitrage activities are generally less extensive in such markets, which may contribute to increased volatility and reduced liquidity of such markets. The limited liquidity of emerging country securities may also affect a Fund’s ability to accurately value its portfolio securities or to acquire or dispose of securities at the price and time it wishes to do so or in order to meet redemption requests.

Many emerging market countries suffer from uncertainty and corruption in their legal frameworks. Legislation may be difficult to interpret and laws may be too new to provide any precedential value. Laws regarding foreign investment and private property may be weak or non-existent. Sudden changes in governments may result in policies which are less favorable to investors such as policies designed to expropriate or nationalize “sovereign” assets. Certain emerging market countries in the past have expropriated large amounts of private property, in many cases with little or no compensation, and there can be no assurance that such expropriation will not occur in the future.

Foreign investment in the securities markets of certain emerging countries is restricted or controlled to varying degrees. These restrictions may limit a Fund’s investment in certain emerging countries and may increase the expenses of the Fund. Certain emerging countries require governmental approval prior to investments by foreign persons or limit investment by foreign persons to only a specified percentage of an issuer’s outstanding securities or a specific class of securities which may have less advantageous terms (including price) than securities of the company available for purchase by nationals.

Many emerging market countries lack the social, political, and economic stability characteristic of the United States. Political instability among emerging market countries can be common and may be caused by an uneven distribution of wealth, social unrest, labor strikes, civil wars, and religious oppression. Economic instability in emerging market countries may take the form of: (i) high interest rates; (ii) high levels of inflation, including hyperinflation; (iii) high levels of unemployment or underemployment; (iv) changes in government economic and tax policies, including confiscatory taxation; and (v) imposition of trade barriers.

A Fund’s income and, in some cases, capital gains from foreign securities will be subject to applicable taxation in certain of the emerging market countries in which it invests, and treaties between the United States and such countries may not be available in some cases to reduce the otherwise applicable tax rates.

Emerging markets also have different clearance and settlement procedures, and in certain of these emerging markets there have been times when settlements have been unable to keep pace with the volume of securities transactions, making it difficult to conduct such transactions.

In the past, governments within the emerging markets have become overly reliant on the international capital markets and other forms of foreign credit to finance large public spending programs, which in the past have caused huge budget deficits. Often, interest payments have become too overwhelming for a government to meet, representing a large percentage of total

gross domestic product (“GDP”). These foreign obligations have become the subject of political debate and served as fuel for political parties of the opposition, which pressure the government not to make payments to foreign creditors, but instead to use these funds for, among other things, social programs. Either due to an inability to pay or submission to political pressure, foreign governments have been forced to seek a restructuring of their loan and/or bond obligations, have declared a temporary suspension of interest payments or have defaulted. These events have adversely affected the values of securities issued by foreign governments and corporations domiciled in those countries and have negatively affected not only their cost of borrowing, but their ability to borrow in the future as well.

Risks of Investing in Europe. The Economic and Monetary Union of the European Union (the “EU”) requires compliance with restrictions on inflation rates, deficits, interest rates, debt levels and fiscal and monetary controls, each of which may significantly affect every country in Europe. Decreasing imports or exports, changes in governmental or EU regulations on trade, changes in the exchange rate of the euro and recessions among EU members may have a significant adverse effect on the economies of other EU members and their trading partners, including some or all of the emerging markets materials sector countries.

Risks of Investing in Japan. Investments in securities issued by Japanese companies may be subject to additional risks.

  • Political Risk. Historically, Japan has had unpredictable national politics and may experience frequent political turnover. Future political developments may lead to changes in policy that might adversely affect the Fund’s investments.
  • Large Government Debt Risk. The Japanese economy faces several concerns, including a financial system with large levels of nonperforming loans, over-leveraged corporate balance sheets, extensive cross-ownership by major corporations, a changing corporate governance structure, and large government deficits. These issues may cause a slowdown of the Japanese economy.
  • Currency Risk. The Japanese yen has fluctuated widely at times and any increase in its value may cause a decline in exports that could weaken the economy.
  • Labor Risk. Japan has an aging workforce. It is a labor market undergoing fundamental structural changes, as traditional lifetime employment clashes with the need for increased labor mobility, which may adversely affect Japan’s economic competitiveness.
  • Geographic Risk. Natural disasters, such as earthquakes, could occur in Japan or surrounding areas and could negatively affect the Japanese economy, and, in turn, could negatively affect the Fund.

Risks of Investing in Non-U.S. Equity Securities. Certain of the Funds invest a significant portion of their assets in non-U.S. equity securities. Investing in securities issued by issuers domiciled in countries other than the domicile of the investor and denominated in currencies other than an investor’s local currency entails certain considerations and risks not typically encountered by the investor in making investments in its home country and in that country’s currency. These considerations include favorable or unfavorable changes in interest rates, currency exchange rates, exchange control regulations and the costs that may be incurred in connection with conversions between various currencies. Investing in any of these Funds also involves certain risks and considerations not typically associated with investing in a fund whose portfolio contains exclusively securities of U.S. issuers. These risks include generally less liquid and less efficient securities markets; generally greater price volatility; less publicly available information about issuers; the imposition of withholding or other taxes; the imposition of restrictions on the expatriation of funds or other assets of the Funds; higher transaction and custody costs; delays and risks attendant in settlement procedures; difficulties in enforcing contractual obligations; lower liquidity and significantly smaller market capitalization; different accounting and disclosure standards; lower levels of regulation of the securities markets; more substantial government interference with the economy; higher rates of inflation; greater social, economic, and political uncertainty; the risk of nationalization or expropriation of assets; and the risk of war.

Risks of Investing in North America. The United States is Canada’s and Mexico’s largest trading and investment partner. The Canadian and Mexican economies are significantly affected by developments in the U.S. economy. Since the implementation of the North American Free Trade Agreement (“NAFTA”) in 1994 among Canada, the United States and Mexico, total merchandise trade between the three countries have increased. To further this relationship, the three NAFTA countries entered into the Security and Prosperity Partnership of North America in March 2005, which may further affect Canada’s and Mexico’s dependency on the U.S. economy. Economic events in any one North American country can have a significant economic effect on the entire North American region, and on some or all of the North American countries in which the Fund invests.

Risks of Investing in Real Estate Companies. Companies that invest in, develop, or operate real estate, or provide real estate related services (“Real Estate Companies”), such as REITs, real estate holding companies, or real estate management or development companies expose investors to the risks of owning real estate directly as well as to risks that relate specifically to the way in which Real Estate Companies are organized and operated. Real estate is highly sensitive to general and local economic conditions and developments, and characterized by intense competition and periodic overbuilding.

  • Concentration Risk. Real Estate Companies may lack diversification due to ownership of a limited number of properties and concentration in a particular geographic region or property type.
  • Interest Rate Risk. Rising interest rates could result in higher costs of capital for Real Estate Companies, which could negatively impact a Real Estate Company’s ability to meet its payment obligations.
  • Leverage Risk. Real Estate Companies may use leverage (and some may be highly leveraged), which increases investment risk and the risks normally associated with debt financing and could adversely affect a Real Estate Company’s operations and market value in periods of rising interest rates. Financial covenants related to a Real Estate Company’s leveraging may affect the ability of the Real Estate Company to operate effectively. In addition, real property may be subject to the quality of credit extended and defaults by borrowers and tenants. If the properties do not generate sufficient income to meet operating expenses, including, where applicable, debt service, ground lease payments, tenant improvements, third-party leasing commissions and other capital expenditures, the income and ability of a Real Estate Company to make payments of any interest and principal on its debt securities will be adversely affected.
  • Liquidity Risk. Investing in Real Estate Companies may involve risks similar to those associated with investing in small capitalization companies. Real Estate Company securities, like the securities of other smaller companies, may be more volatile than, and perform differently from, shares of large capitalization companies. There may be less trading in Real Estate Company shares, which means that buy and sell transactions in those shares could have a magnified impact on share price, resulting in abrupt or erratic price fluctuations. In addition, real estate is relatively illiquid and, therefore, a Real Estate Company may have a limited ability to vary or liquidate properties in response to changes in economic or other conditions.
  • Management Risk. Real Estate Companies are dependent upon management skills and may have limited financial resources. Real Estate Companies are generally not diversified and may be subject to heavy cash flow dependency, default by borrowers and self-liquidation. In addition, transactions between Real Estate Companies and their affiliates may be subject to conflicts of interest, which may adversely affect a Real Estate Company’s shareholders. A Real Estate Company may also have joint venture investments in certain of its properties and, consequently, its ability to control decisions relating to such properties may be limited.
  • Property Risk. Real Estate Companies may be subject to risks relating to functional obsolescence or reduced desirability of properties; extended vacancies due to economic conditions and tenant bankruptcies; catastrophic events such as earthquakes, hurricanes and terrorist acts; and casualty or condemnation losses. Real estate income and values also may be greatly affected by demographic trends, such as population shifts or changing tastes and values, or increasing vacancies or declining rents resulting from legal, cultural, technological, global or local economic developments.
  • Regulatory Risk. Real estate income and values may be adversely affected by such factors as applicable domestic and foreign laws (including tax laws). Government actions, such as tax increases, zoning law changes or environmental regulations, also may have a major impact on real estate.
  • Repayment Risk. The prices of real estate company securities may drop because of the failure of borrowers to repay their loans, poor management, and the inability to obtain financing either on favorable terms or at all. If the properties do not generate sufficient income to meet operating expenses, including, where applicable, debt service, ground lease payments, tenant improvements, third-party leasing commissions and other capital expenditures, the income and ability of the real estate company to make payments of interest and principal on their loans will be adversely affected. Many real estate companies utilize leverage, which increases investment risk and could adversely affect a company’s operations and market value in periods of rising interest rates.

Risks of Investing in Sub-Saharan Africa. The economies of certain sub-Saharan African countries have experienced high unemployment, famine, currency volatility, inflation, general economic malaise, and internal and external conflicts that have resulted in significant displacement of local populations. While countries in the region, such as South Africa, Gabon and Botswana, have experienced greater political stability and economic growth than neighboring states, adverse social and economic conditions in one country may have a significant adverse effect on other countries of this region, including some or all of the emerging markets countries in which the Funds invest.

Risks of Investing in the Automotive Industry. The automotive industry can be highly cyclical, and companies in the automotive industry may suffer periodic losses. The automotive industry is also highly competitive and there may be, at times, excess capacity in the global and domestic automotive industry. Over the last few years the U.S. automotive industry experienced a significant downturn, certain automotive companies required stimulus from the U.S. government, while others formed strategic industry alliances in order to weather the substantially difficult market conditions. In general, the automotive industry is susceptible to labor disputes, product defect litigation, patent expiration, increased pension liabilities, rise in material or component prices and changing consumer tastes.

Risks of Investing in the Basic Materials Sector. Issuers in the basic materials sector could be adversely affected by commodity price volatility, exchange rates, import controls and increased competition. Production of industrial materials often exceeds demand as a result of over-building or economic downturns, leading to poor investment returns. Issuers in the basic materials sector are at risk for environmental damage and product liability claims and may be adversely affected by depletion of resources, delays in technical progress, labor relations and government regulations.

Risks of Investing in the Biotechnology Sector. Biotechnology companies depend on the successful development of new and proprietary technologies. There can be no assurance that the development of new technologies will be successful or that intellectual property rights will be obtained with respect to new technologies. The loss or impairment of intellectual property rights may adversely affect the profitability of biotechnology companies. In addition, companies in the biotechnology industry spend heavily on research and development and their products or services may not prove commercially successful or may become obsolete quickly. The risks of high development costs may be exacerbated by the inability to raise prices as a result of managed care pressure, government regulation or price controls. Biotechnology companies can suffer persistent losses during the transition of new products from development to production or when products are or may be subject to regulatory approval processes or regulatory scrutiny and, as a consequence, the earnings of biotechnology companies may be erratic. Companies in the biotechnology sector are also exposed to the risk that they will be subject to products liability claims. Companies involved in the biotechnology industry may be subject to extensive government regulations by the Food and Drug Administration, the Environmental Protection Agency and the United States Department of Agriculture, among other foreign and domestic regulators. Such regulation may significantly affect and limit biotechnology research, product development and approval of products.

Risks of Investing in the Capital Goods Sector. The capital goods sector may be affected by fluctuations in the business cycle and by other factors affecting manufacturing demands. The capital goods sector depends heavily on corporate spending. The capital goods sector may perform well during times of economic expansion, and as economic conditions worsen, the demand for capital goods may decrease. Many capital goods are sold internationally and such companies are subject to market conditions in other countries and regions.

Risks of Investing in the Commercial and Professional Services Sector. The success of commercial and professional service providers is tied closely to the performance of domestic and international economies, interest rates, exchange rates, competition, availability of qualified personnel and corporate demand. The commercial and professional services sector depends heavily on corporate spending. Companies in the commercial and professional services sector may be subject to severe competition, which may also have an adverse impact on their profitability.

Risks of Investing in the Consumer Discretionary Sector. Companies engaged in the design, production or distribution of products or services for the consumer discretionary sector (including, without limitation, television and radio broadcasting, manufacturing, publishing, recording and musical instruments, motion pictures, photography, amusement and theme parks, gaming casinos, sporting goods and sports arenas, camping and recreational equipment, toys and games, apparel, travel-related services, automobiles, hotels and motels, and fast food and other restaurants) are subject to the risk that their products or services may become obsolete quickly. The consumer discretionary sector can be significantly affected by several factors, including, without limitation, the performance of domestic and international economies, exchange rates, changing consumer tastes and trends, marketing campaigns, cyclical revenue generation, consumer confidence, commodity price volatility, labor relations, interest rates, import and export controls, intense competition, technological developments and government regulation.

Risks of Investing in the Consumer Goods Sector. The consumer goods sector may be strongly affected by trends, marketing campaigns and other factors affecting consumer demand. Governmental regulation affecting the use of various food additives may affect the profitability of certain companies in the consumer goods sector. In addition, tobacco companies may be adversely affected by new laws, regulations and litigation. Many consumer goods may be marketed globally, and consumer goods companies may be affected by the demand and market conditions in other countries and regions.

Risks of Investing in the Consumer Services Sector. The success of consumer product manufacturers and retailers (including food and drug retailers, general retailers, media, and travel and leisure) is tied closely to the performance of the domestic and international economy, interest rates, exchange rates, competition and consumer confidence. The consumer services sector depends heavily on disposable household income and consumer spending. Companies in the consumer services sector may be subject to severe competition, which may also have an adverse impact on their profitability. Changes in demographics and consumer preferences may affect the success of consumer products.

Risks of Investing in the Consumer Staples Sector. Companies in the consumer staples sector may be adversely affected by changes in the global economy, consumer spending, competition, demographics and consumer preferences, and production spending. Companies in the consumers staples sector are also affected by changes in government regulation, global economic, environmental and political events, economic conditions and the depletion of resources. In addition, companies in the consumers staples sector may be subject to risks pertaining to the supply of, demand for and prices of raw materials. The prices of raw materials fluctuate in response to a number of factors, including, without limitation, changes in government agricultural support programs, exchange rates, import and export controls, changes in international agricultural and trading policies, and seasonal and weather conditions.

Risks of Investing in the Energy Sector. Companies in the energy sector are strongly affected by the levels and volatility of global energy prices, energy supply and demand, government regulations and policies, energy production and conservation, efforts and technological change. Prices and supplies of energy may fluctuate significantly over short and long periods of time due to national and international political changes, Organization of Petroleum Exporting Countries (“OPEC”) policies, changes in relationships among OPEC members and between OPEC and oil-importing nations, the regulatory environment, taxation policies, and the economy of the key energy-consuming countries. In addition, companies in the energy sector are at risk of civil liability from accidents resulting in injury, loss of life or property, pollution or other environmental damage claims and risk of loss from terrorism and natural disasters. Disruptions in the oil industry or shifts in fuel consumption may significantly impact companies in this sector. In addition, because a significant portion of revenues of companies in this sector are derived from a relatively small number of customers that are largely composed of governmental entities and utilities, governmental budget constraints may have a significant impact on the stock prices of companies in this industry.

Risks of Investing in the Financial Sector. Companies in the financial sector include regional and money center banks, securities brokerage firms, asset management companies, savings banks and thrift institutions, specialty finance companies (e.g., credit card, mortgage providers), insurance and insurance brokerage firms, financial conglomerates and foreign banking and financial companies. Market conditions and regulation of the financial sector in China may be particularly subject to change based on government policy. The global financial markets have recently experienced very difficult conditions and volatility as well as significant adverse trends. The deteriorating conditions in these markets have resulted in a decrease in availability of corporate credit, capital and liquidity and have led indirectly to the insolvency, closure or acquisition of a number of financial institutions. These conditions have also contributed to consolidation within the financial industry. In addition, the global financial industry has been materially and adversely affected by a significant decline in the value of mortgage-backed and asset-backed securities, and by the sovereign debt crisis. The prospects of many financial companies are questionable and continue to evolve as financial companies revise their outlooks and write down assets that they hold.

Most financial companies are subject to extensive governmental regulation, which limits their activities and may affect their ability to earn a profit from a given line of business. Government regulation may change frequently and may have significant adverse consequences for companies in the financial sector, including effects not intended by the regulation. Direct governmental intervention in the operations of financial companies and financial markets may materially and adversely affect the companies in which a Fund invests, including recent legislation in many countries that may increase government regulation, repatriation and other intervention. The impact of governmental intervention and recent legislation on any individual financial company or on the financial sector as a whole cannot be predicted. The valuation of financial companies has been and continues to be subject to unprecedented volatility and may be influenced by unpredictable factors, including interest rate risk and sovereign debt default. Certain financial businesses are subject to intense competitive pressures, including market share and price competition. Financial companies in foreign countries are subject to market specific and

general regulatory and interest rate concerns. In particular, government regulation in certain foreign countries may include taxes and controls on interest rates, credit availability, minimum capital requirements, ban on short sales, prices and currency transfers.

The profitability of banks, savings and loan associations and financial companies is largely dependent on the availability and cost of capital funds and can fluctuate significantly when interest rates change. In addition, general economic conditions are important to the operations of these concerns, with exposure to credit losses resulting from financial difficulties of borrowers having an adverse effect on the profitability of financial companies. Financial companies can be highly dependent upon access to capital markets and any impediments to such access, such as adverse overall economic conditions or a negative perception in the capital markets of a financial company’s financial condition or prospects, could adversely affect its business.

Risks of Investing in the Health Care Sector. Companies in the health care sector are often issuers whose profitability may be affected by extensive government regulation, restrictions on government reimbursement for medical expenses, rising or falling costs of medical products and services, pricing pressure, an increased emphasis on outpatient services, limited number of products, industry innovation, changes in technologies and other market developments. Many health care companies are heavily dependent on patent protection and the actual or perceived safety and efficiency of their products. The expiration of patents may adversely affect the profitability of these companies. Many health care companies are subject to extensive litigation based on product liability and similar claims. Health care companies are subject to competitive forces that may make it difficult to raise prices and, in fact, may result in price discounting. Many new products in the health care sector may be subject to regulatory approvals. The process of obtaining such approvals may be long and costly, and may diminish the opportunity for a company to profit from a new product or to bring a new product to market. Many health care-related companies are relatively small and unseasoned. Health care companies may also be strongly affected by scientific bio-technology or technological developments and their products may quickly become obsolete. Also, many health care companies offer products and services that are subject to governmental regulation and may be adversely affected by changes in governmental policies or laws. The impact of recent legislation passed by the U.S. government and other legislation introduced or considered by other governments on any individual health care company or on the health care sector as a whole cannot be predicted. These laws and proposals span a wide range of topics, including cost control, national health insurance, incentives for compensation in the provision of health care services, tax incentives and penalties related to health care insurance premiums, and promotion of prepaid health care plans. No one can predict what proposals will be enacted or what potentially adverse effect they may have on health care-related or biotechnology-related companies.

Risks of Investing in the Industrials Sector. The stock prices of companies in the industrials sector are affected by supply and demand both for their specific product or service and for industrials sector products in general. The products of manufacturing companies may face product obsolescence due to rapid technological developments and frequent new product introduction. Government regulations, world events and economic conditions affect the performance of companies in the industrials sector. Companies in the industrials sector may be adversely affected by liability for environmental damage, product liability claims and exchange rates. The industrials sector may also be adversely affected by changes or trends in commodity prices, which may be influenced by unpredictable factors. Aerospace and defense companies, a component of the industrials sector, can be significantly affected by government spending policies because companies involved in this industry rely, to a significant extent, on U.S. and other government demand for their products and services. Thus, the financial condition of, and investor interest in, aerospace and defense companies are heavily influenced by governmental defense spending policies, which are typically under pressure from efforts to control the U.S. and other government budgets. Transportation stocks, a component of the industrials sector, are cyclical and can be significantly affected by economic changes, fuel prices, labor relations and insurance costs. Transportation companies in certain countries may also be subject to significant government regulation and oversight, which may adversely affect their businesses.

Risks of Investing in the Information Technology Sector. Information technology companies face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Like other technology companies, information technology companies may have limited product lines, markets, financial resources or personnel. The products of information technology companies may face product obsolescence due to rapid technological developments and frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Companies in the information technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies.

Risks of Investing in the Insurance Industry. The insurance industry is subject to extensive government regulation in some countries and can be significantly affected by changes in interest rates, general economic conditions, price and marketing competition, the imposition of premium rate caps or other changes in government regulation or tax law. Different segments of the insurance industry can be significantly affected by mortality and morbidity rates, environmental clean-up costs and catastrophic events such as earthquakes, hurricanes and terrorist acts.

Risks of Investing in the Materials Sector. Companies in the materials sector could be adversely affected by commodity price volatility, exchange rates, import controls, increased competition, depletion of resources, technical progress, labor relations, exchange rates and government regulations, among other factors. Also, companies in the materials sector are at risk of liability for environmental damage and product liability claims. Production of materials may exceed demand as a result of market imbalances or economic downturns, leading to poor investment returns.

Risks of Investing in the Media Sector. Companies in the media sector may encounter distressed cash flows due to the need to commit substantial capital to meet increasing competition, particularly in formulating new products and services using new technology. Media companies are subject to risks that include cyclicality of revenues and earnings, a potential decrease in the discretionary income of targeted individuals, changing consumer tastes and interests, competition in the industry and the potential for increased state and federal regulation. Advertising spending is an important source of revenue for media companies. During economic downturns advertising spending typically decreases and as a result, media companies tend to generate less revenue.

Risks of Investing in the Natural Resources Sector. The profitability of companies in the natural resources sector can be affected by worldwide energy prices, limits on exploration, and production spending. Companies in the natural resources sector are affected by government regulation, world events and economic conditions. Companies in the natural resources sector are at risk for environmental damage claims. Companies in the natural resources sector could be adversely affected by commodity price volatility, changes in exchange rates, imposition of import controls and increased competition. Companies in the natural resources sector may be adversely affected by depletion of natural resources, technological developments, and labor relations.

Risks of Investing in the Oil and Gas Sector. Companies in the oil and gas sector are strongly affected by the levels and volatility of global energy prices, oil and gas supply and demand, government regulations and policies, oil and gas production and conservation efforts and technological change. Prices and supplies of oil and gas may fluctuate significantly over short and long periods of time due to national and international political changes, Organization of Petroleum Exporting Countries (“OPEC”) policies, changes in relationships among OPEC members and between OPEC and oil-importing nations, the regulatory environment, taxation policies, and the economies of key energy-consuming countries. Disruptions in the oil industry or shifts in energy consumption may significantly impact companies in this sector.

Risks of Investing in the Pharmaceuticals Industry. Companies in the pharmaceuticals industry are subject to competitive forces that may make it difficult to raise prices and, in fact, may result in price discounting. The profitability of some companies in the pharmaceuticals industry may be dependent on a relatively limited number of products. In addition, their products can become obsolete due to industry innovation, changes in technologies or other market developments. Many new products in the pharmaceuticals industry are subject to government approvals, regulation and reimbursement rates. The process of obtaining government approvals may be long and costly. Many companies in the pharmaceuticals industry are heavily dependent on patent protection. The expiration of patents may adversely affect the profitability of these companies. Companies in the pharmaceutical industry may be subject to extensive litigation based on product liability and similar claims.

Risks of Investing in the Retail Sector. The retail sector may be affected by changes in domestic and international economies, consumer confidence, disposable household income and spending, and consumer tastes and preferences. Companies in the retail sector face intense competition, which may have an adverse effect on their profitability. The success of companies in the retail sector may be strongly affected by social trends and marketing campaigns. Companies in the retail sector may be dependent on outside financing, which may be difficult to obtain. Many of these companies are dependent on third party suppliers and distribution systems. Retail companies may be unable to protect their intellectual property rights or may be liable for infringing the intellectual property rights of others.

Risks of Investing in the Technology Sector. Technology companies face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Technology companies may have limited product lines, markets, financial resources or personnel. The products of technology companies may face product obsolescence due to rapid technological developments and frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Companies in the technology sector are heavily dependent on patent and

intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies. The technology sector may also be adversely affected by changes or trends in commodity prices, which may be influenced or characterized by unpredictable factors.

Risks of Investing in the Telecommunications Sector. The telecommunications sector of an economy is often subject to extensive government regulation. The costs of complying with governmental regulations, delays or failure to receive required regulatory approvals or the enactment of new adverse regulatory requirements may adversely affect the business of the telecommunications companies. Government actions around the world, specifically in the area of pre-marketing clearance of products and prices, can be arbitrary and unpredictable. Companies in the telecommunications sector may encounter distressed cash flows due to the need to commit substantial capital to meet increasing competition, particularly in formulating new products and services using new technology. Technological innovations may make the products and services of telecommunications companies obsolete.

Risks of Investing in the Transportation Sector. Issuers in the transportation sector can be significantly affected by economic changes, fuel prices, labor relations, and insurance costs. Transportation companies in certain countries may also be subject to significant government regulation and oversight, which may adversely affect their businesses. Other risk factors that may affect transportation companies include the risk of increases in fuel and other operating costs and the effects of regulatory changes or other government decisions.

Risk of Investing in the United States. The United States is a significant, and in some cases the most significant, trading partner of or foreign investor in certain emerging markets and the economies of these countries may be particularly affected by adverse changes in the U.S. economy. Decreasing U.S. imports, new trade regulations, changes in the U.S. dollar exchange rates or a recession in the United States may have a material adverse effect on the economies of these nations.

Risks of Investing in the Utilities Sector. Investments in utility companies involve special considerations, including the risk of changing commodity prices, government regulation stipulating rates charged by utilities, increased tariffs, changes in tax laws, interest rate fluctuations and changes in the cost of providing the specific utility services. The utilities industry is also subject to potential terrorist attacks, natural disasters and severe weather conditions, as well as regulatory and operational burdens associated with the operation and maintenance of nuclear facilities. Government regulators monitor and control utility revenues and costs, and therefore may limit utility profits. In certain countries regulatory authorities may also restrict a company’s access to new markets, thereby diminishing a company’s long-term prospects. The deregulation of certain utilities companies may eliminate restrictions on profits but may also subject these companies to greater risks of loss.

Risks of Swap Agreements. The risk of loss with respect to swaps generally is limited to the net amount of payments that a Fund is contractually obligated to make. Swap agreements are subject to the risk that the swap counterparty will default on its obligations. If such a default occurs, a Fund will have contractual remedies pursuant to the agreements related to the transaction. However, such remedies may be subject to bankruptcy and insolvency laws which could affect such Fund’s rights as a creditor (e.g., a Fund may not receive the net amount of payments that it is contractually entitled to receive).

Proxy Voting Policy

The Trust has adopted, as its proxy voting policies for each Fund, the proxy voting guidelines of BFA, the investment adviser to each Fund. The Trust has delegated to BFA the responsibility for voting proxies on the portfolio securities held by each Fund. The remainder of this section discusses each Fund’s proxy voting guidelines and BFA’s role in implementing such guidelines.

BFA votes (or refrains from voting) proxies for each Fund in a manner that BFA, in the exercise of its independent business judgment, concludes is in the best economic interests of such Fund. In some cases, BFA may determine that it is in the best economic interests of a Fund to refrain from exercising the Fund’s proxy voting rights (such as, for example, proxies on certain non-U.S. securities that might impose costly or time-consuming in-person voting requirements). With regard to the relationship between securities lending and proxy voting, BFA’s approach is also driven by each Fund’s economic interests. The evaluation of the economic desirability of recalling loans involves balancing the revenue-producing value of loans against the likely economic value of casting votes. Based on our evaluation of this relationship, we believe that the likely economic value of casting a vote generally is less than the securities lending income, either because the votes will not have significant economic consequences or because the outcome of the vote would not be affected by BFA recalling loaned securities in order to ensure they are voted. Periodically, BFA analyzes the process and benefits of voting proxies for securities on loan, and

will consider whether any modification of its proxy voting policies or procedures are necessary in light of any regulatory changes. BFA will normally vote on specific proxy issues in accordance with its proxy voting guidelines. BFA’s proxy voting guidelines provide detailed guidance as to how to vote proxies on certain important or commonly raised issues. BFA may, in the exercise of its business judgment, conclude that the proxy voting guidelines do not cover the specific matter upon which a proxy vote is requested, or that an exception to the proxy voting guidelines would be in the best economic interests of a Fund. BFA votes (or refrains from voting) proxies without regard to the relationship of the issuer of the proxy (or any shareholder of such issuer) to a Fund, a Fund’s affiliates (if any), BFA or BFA’s affiliates, or the Distributor or the Distributor’s affiliates. When voting proxies, BFA attempts to encourage issuers to follow practices that enhance shareholder value and increase transparency and allow the market to place a proper value on their assets. With respect to certain specific issues:

  • Each Fund generally supports the board’s nominees in the election of directors and generally supports proposals that strengthen the independence of boards of directors;
  • Each Fund generally does not support proposals on social issues that lack a demonstrable economic benefit to the issuer and the Fund investing in such issuer; and
  • Each Fund generally votes against anti-takeover proposals and proposals that would create additional barriers or costs to corporate transactions that are likely to deliver a premium to shareholders.

BFA maintains institutional policies and procedures that are designed to prevent any relationship between the issuer of the proxy (or any shareholder of the issuer) and a Fund, a Fund’s affiliates (if any), BFA or BFA’s affiliates (if any) or the Distributor or the Distributor’s affiliates, from having undue influence on BFA’s proxy voting activity. In certain instances, BFA may determine to engage an independent fiduciary to vote proxies as a further safeguard against potential conflicts of interest or as otherwise required by applicable law. The independent fiduciary may either vote such proxies or provide BFA with instructions as to how to vote such proxies. In the latter case, BFA votes the proxy in accordance with the independent fiduciary’s determination.

Information with respect to how BFA voted proxies relating to the Funds’ portfolio securities during the 12-month period ended June 30 is available: (i) without charge, upon request, by calling 1-800-iShares (1-800-474-2737) or through the Funds’ website at www.iShares.com; and (ii) on the SEC’s website at www.sec.gov.

Portfolio Holdings Information

The Board has adopted a policy regarding the disclosure of the Funds’ portfolio holdings information that requires that such information be disclosed in a manner that: (i) is consistent with applicable legal requirements and in the best interests of each Fund’s respective shareholders; (ii) does not put the interests of BFA, the Distributor or any affiliated person of BFA or the Distributor, above those of Fund shareholders; (iii) does not advantage any current or prospective Fund shareholders over any other current or prospective Fund shareholders, except to the extent that certain Entities (as described below) may receive portfolio holdings information not available to other current or prospective Fund shareholders in connection with the dissemination of information necessary for transactions in Creation Units, as contemplated by the iShares Exemptive Orders and as discussed below; and (iv) does not provide selective access to portfolio holdings information except pursuant to the procedures outlined below and to the extent appropriate confidentiality arrangements limiting the use of such information are in effect. The “Entities” referred to in sub-section (iii) above are generally limited to National Securities Clearing Corporation (“NSCC”) members, subscribers to various fee-based subscription services, large institutional investors (known as “Authorized Participants”) that have been authorized by the Distributor to purchase and redeem large blocks of shares pursuant to legal requirements, including exemptive orders granted by the SEC pursuant to which the Funds offer and redeem their shares (“iShares Exemptive Orders”) and other institutional market participants and entities that provide information services.

Each business day, each Fund’s portfolio holdings information is provided to the Distributor or other agent for dissemination through the facilities of the NSCC and/or other fee-based subscription services to NSCC members and/or subscribers to those other fee-based subscription services, including Authorized Participants, and to entities that publish and/or analyze such information in connection with the process of purchasing or redeeming Creation Units or trading shares of the Funds in the secondary market. This information typically reflects each Fund’s anticipated holdings on the following business day.

Daily access to information concerning the Funds’ portfolio holdings is permitted (i) to certain personnel of those service providers that are involved in portfolio management and providing administrative, operational, risk management, or other

support to portfolio management, including affiliated broker-dealers and Authorized Participants; and (ii) to other personnel of the Funds’ investment adviser and the Distributor, administrator, custodian and fund accountant who deal directly with or assist in, functions related to investment management, distribution, administration, custody and fund accounting, as may be necessary to conduct business in the ordinary course in a manner consistent with the iShares Exemptive Orders, agreements with the Funds and the terms of the Funds’ current registration statements. In addition, each Fund discloses its portfolio holdings and the percentages they represent of the Fund’s net assets at least monthly, and as often as each day the Fund is open for business, at www.iShares.com. More information about this disclosure is available at www.iShares.com.

Portfolio holdings information made available in connection with the creation/redemption process may be provided to other entities that provide services to the Funds in the ordinary course of business after it has been disseminated to the NSCC. From time to time, information concerning portfolio holdings other than portfolio holdings information made available in connection with the creation/redemption process, as discussed above, may be provided to other entities that provide services to the Funds, including rating or ranking organizations, in the ordinary course of business, no earlier than one business day following the date of the information.

Each Fund discloses its complete portfolio holdings schedule in public filings with the SEC within 70 days after the end of each fiscal quarter and will provide that information to shareholders as required by federal securities laws and regulations thereunder. A Fund may, however, voluntarily disclose all or part of its portfolio holdings other than in connection with the creation/redemption process, as discussed above, in advance of required filings with the SEC, provided that such information is made generally available to all shareholders and other interested parties in a manner that is consistent with the above policy for disclosure of portfolio holdings information. Such information may be made available through a publicly-available website or other means that make the information available to all likely interested parties contemporaneously.

The Trust’s Chief Compliance Officer may authorize disclosure of portfolio holdings information pursuant to the above policy and procedures.

The Board reviews the policy and procedures for disclosure of portfolio holdings information at least annually.

Construction and Maintenance of the Underlying Indexes

Descriptions of the Underlying Indexes are provided below.

The FTSE Global Equity Index Series

FTSE China 25 Index

Number of Components: 25

Index Description. The FTSE China 25 Index is designed to represent the performance of the largest companies in the China equity market that are available to international investors. The Underlying Index consists of 25 of the largest and most liquid Chinese companies. The securities in the Underlying Index are weighted based on the total market value of their shares. Securities with higher total market values generally have a higher representation in the Underlying Index. Underlying Index constituents are screened for liquidity and weightings are capped to avoid over-concentration in any one stock.

The Underlying Index consists of “Red Chip” shares and “H” shares.

Component Selection Criteria. The Underlying Index is primarily rule-based, but is also monitored by a governing committee. The Secretary to the Underlying Index is responsible for conducting a quarterly review of constituents for the Underlying Index and for recommending to the governing committee any constituents to be inserted or deleted as part of the quarterly review. All eligible securities are ranked by their full market capitalizations.

Eligibility. Each security included in the Underlying Index is a current constituent of the FTSE All-World Index, an index of the FTSE Global Equity Index Series. All classes of equity securities in issue are eligible for inclusion in the Underlying Index subject to conforming with free-float and liquidity restrictions.

Float-Adjusted Market Capitalization. When calculating index weights, individual constituents’ shares held by governments, corporations, strategic partners, or other control groups are excluded from the company’s outstanding shares. Shares owned by other companies are also excluded regardless of whether they are index constituents. In countries with regulated environments, where a foreign investment limit exists at the sector or company level, the constituent’s weight will reflect either the foreign investment limit or the percentage float, whichever is more restrictive.

Liquidity. Stocks are screened to ensure there is sufficient liquidity to be traded. Factors in determining liquidity include the availability of current and reliable price information and the level of trading volume relative to shares outstanding. Value traded and float turnover are also analyzed on a monthly basis to review liquidity.

Index Maintenance and Issue Changes. The FTSE Global Classification Committee is responsible for the industry classification of constituents of the Underlying Index within the FTSE Global Classification System. The FTSE Global Classification Committee may approve changes to the FTSE Global Classification System and Management Rules. FTSE appoints the Chairman and Deputy Chairman of the Underlying Index. The Chairman, or in his absence Deputy Chairman, will chair meetings of the Committee and will represent that Committee outside meetings. The Chairman and Deputy Chairman of the Index Committee are collectively responsible for approving constituent changes to the Underlying Index between meetings of the Committee on advice from the Secretary to the Committee and as permitted and as specified by the Underlying Index’s Ground Rules.

Additions. A company is added to the Underlying Index at the periodic review if it rises to the 15th position or above when the eligible companies are ranked by full market value before the application of any investibility weightings.

Deletions. A company in the Underlying Index is deleted at the periodic review if it falls to the 36th position or below when the eligible companies are ranked by full market value before the application of any investibility weighting. Any deletion to the Underlying Index will simultaneously entail an addition to the Underlying Index in order to maintain 25 Index constituents at all times.

Revisions to the Float Adjustments. The Underlying Index is reviewed quarterly for changes in free float. These reviews coincide with quarterly reviews undertaken of the Underlying Index. Implementation of any changes takes place after the close of the Underlying Index calculation on the third Friday in March, June, September and December.

Quarterly Index Rebalancing. The quarterly review of the Underlying Index constituents takes place in March, June, September and December. Any constituent changes are implemented on the next trading day following the third Friday of the same month of the review meeting. Details of the outcome of the review and the dates on which any changes are to be implemented are published as soon as possible after the Index Committee meeting has concluded. Significant Underlying Index rebalancing may cause funds based on the Underlying Index to experience trading error.

Index Availability. The Underlying Index is calculated continuously during Hong Kong trading hours and is widely disseminated to major data vendors. The Underlying Index will not be calculated on Hong Kong public holidays.

Exchange Rates and Pricing. The Underlying Index uses Reuters’ real-time foreign exchange spot rates and Reuters’ real-time security prices. The Underlying Index is calculated in Hong Kong Dollars. Non-Hong Kong Dollar denominated constituent prices are converted to Hong Kong Dollars in order to calculate the Underlying Index. The foreign exchange rates and security prices received from Reuters at the closing time of the Underlying Index are used to calculate the final index levels.

FTSE China (HK Listed) Index

Number of Components: approximately 112

Index Description. The FTSE China (HK Listed) Index is designed to track the performance of the large- and mid-capitalization companies in the Chinese equity market that are available to international investors. The Underlying Index consists of many of the largest and most liquid Chinese companies. Securities in the Underlying Index are weighted based on the total market value of their shares so that securities with higher total market values generally have a higher representation in the Underlying Index. All securities in the Underlying Index currently trade on the Hong Kong Stock Exchange (“HKEX”). As of September 28, 2011, the Underlying Index consisted of 112 companies.

The Underlying Index consists of two types of shares: “Red Chip” shares and “H” shares.

“Red Chip” shares are incorporated in Hong Kong and trade on the HKEX. They are quoted in Hong Kong Dollars. Red Chip companies are substantially owned directly or indirectly by the Chinese Government and have the majority of their business interest in mainland China. Like other securities trading on the HKEX, there are no restrictions on who can trade Red Chip shares.

“H” shares are incorporated in China and nominated by the Central Government for listing and trading on the HKEX. They are quoted and trade in Hong Kong and U.S. dollars. Like other securities trading on the HKEX, there are no restrictions on who can trade “H” shares.

Component Selection Criteria. The Underlying Index is primarily rule-based but is also monitored by a governing committee. The Secretary to the Underlying Index is responsible for conducting a quarterly review of constituents for the Underlying Index and for recommending to the governing committee any constituents to be inserted or deleted as part of the quarterly review. All eligible securities are ranked by their full market capitalizations.

Eligibility. Each security included in the Underlying Index is a current constituent of the FTSE All-World Index, an index of the FTSE Global Equity Index Series. All classes of equity securities in issue are eligible for inclusion in the Underlying Index subject to conforming with free-float and liquidity restrictions.

Float-Adjusted Market Capitalization. When calculating index weights, individual constituents’ shares held by governments, corporations, strategic partners or other control groups are excluded from the company’s outstanding shares. Shares owned by other companies are also excluded regardless of whether they are index constituents. In countries with regulated environments, where a foreign investment limit exists at the sector or company level, the constituent’s weight will reflect either the foreign investment limit or the percentage float, whichever is more restrictive.

Liquidity. Each security is tested for liquidity by calculation of its median daily trading per month. The median trade is calculated by ranking each daily trade total and selecting the middle ranking day. Daily totals with zero trades are included in the ranking, therefore a security that fails to trade for more than half of the days in a month will have a zero median trade.

Securities that do not turn over at least 0.05% of their shares in issue (after the application of any investability weightings) based on their median daily trade per month in ten of the twelve months prior to a full market review will not be eligible for inclusion in the Underlying Index. An existing constituent failing to trade at least 0.04% of its shares in issue (after the application of any investability weightings) based on its median daily trade per month for more than four of the twelve months prior to a full market review will be removed.

Index Maintenance and Issue Changes. Regional FTSE committees are responsible for undertaking review of the Underlying Index and for approving changes.

Corporate actions including new issues, deletions, mergers, splits, suspensions and constituent weight changes in the Underlying Index are applied in the same consistent manner as in the FTSE Global Equity Index Series.

Review Dates. The Underlying Index is reviewed in March using data as at the close of business on the last working day in December. All relevant changes arising from review of the FTSE Global Equity Index Series are also applied to the Underlying Index.

Revisions to the Float Adjustments. The Underlying Index is periodically reviewed for changes in free float. These reviews coincide with quarterly reviews undertaken by the FTSE Regional Committees. Implementation of changes happens at the close of business on the third Friday in March, June, September or December. A constituent’s free float will also be reviewed and adjusted if necessary:

  • by identifying information which necessitates a change in free float weighting or
  • following a corporate event.

Index Availability. The Underlying Index is published every 15 seconds during the Official Index Period, using last trade prices, and is widely disseminated to major data vendors. The Official Index Period is 10:00 to 16:00 local Hong Kong hours. The Underlying Index is not calculated on Hong Kong public holidays.

Exchange Rates and Pricing. The Underlying Index uses Reuters’ real-time foreign exchange spot rates and Reuters’ real-time security prices. The Underlying Index is calculated in Hong Kong Dollars. Non-Hong Kong Dollar denominated constituent prices are converted to Hong Kong Dollars in order to calculate the Underlying Index. The foreign exchange rates and security prices received from Reuters at the closing time of the Underlying Index are used to calculate the final index levels.

FTSE Developed Small Cap ex-North America Index

Number of Components: approximately 2,116

Index Description. The FTSE Developed Small Cap ex-North America Index is market capitalization weighted and measures the stock performance of small-capitalization companies in developed countries outside of North America. As of the close of business on September 30, 2011, the Underlying Index had a total market capitalization of approximately $1,086,141 million. The Underlying Index is calculated with dividends reinvested.

Index Criteria & Methodology. Small-cap equity securities issued outside of North America are generally eligible for the Underlying Index. Exchange traded funds (“ETFs”) and open-end mutual fund companies, whose share price is a direct derivation of the values of underlying holdings, are excluded. Equity securities listed on a stock exchange or market recognized by FTSE are eligible for inclusion but preferred stocks, hybrid securities, and other similar securities are excluded by FTSE. In determining country allocations, FTSE normally allocates a company to the country in which it is incorporated and listed at the time of the company’s listing. However, FTSE reserves the right to defer or change an allocation decision. Eligible securities are required to meet liquidity measures determined by FTSE, including minimum trading volumes and overall and free-float market capitalization amounts.

Index Maintenance and Issue Changes. Regional FTSE committees are responsible for undertaking review of the Underlying Index and for approving changes in constituents in the Underlying Index.

Index Availability. The Underlying Index is calculated in real-time and generally published throughout the business day, and distributed primarily through international data vendors. Daily values are also made available to major newspapers and can be found at the FTSE website. The Underlying Index generally uses real-time trade prices for securities and currency spot rates. The Underlying Index is not calculated on January 1 or December 25.

Currency and Exchange Rates. The Underlying Index is published and calculated using trading values (real-time throughout the day and closing values at the end of the day) and WM/Reuters Closing Spot Rates for currency values.

The MSCI Indexes

The MSCI indexes were founded in 1969 by Capital International S.A. as the first international performance benchmarks constructed to facilitate accurate comparison of world markets. The MSCI single country standard equity indexes have covered the world’s developed markets since 1969 and in 1987 MSCI commenced coverage of emerging markets.

Local stock exchanges traditionally calculated their own indexes, which were generally not comparable with one another due to differences in the representation of the local market, mathematical formulas, base dates and methods of adjusting for capital changes. MSCI, however, applies the same calculation methodology to all markets for all single country standard equity indexes, both developed and emerging.

MSCI’s Global Investable Market Indexes (the “MSCI GIMI”) provide exhaustive coverage and non-overlapping market segmentation by market capitalization size and by style. The MSCI GIMI intends to target approximately 99% coverage of the free-float adjusted market capitalization in each market of large, mid and small cap securities.

  • MSCI Global Standard Indexes cover all investable large and mid cap securities by including approximately 85% of each market’s free-float adjusted market capitalization.
  • MSCI Global Small Cap Indexes provide coverage to all companies with a market capitalization below that of the companies in the MSCI Global Standard Indexes by including above and beyond the coverage of the MSCI Global Standard Indexes.

MSCI Global Investable Market Indexes

Selection Criteria. MSCI’s index construction process involves: (i) defining the equity universe; (ii) determining the market investable equity universe for each market; (iii) determining market capitalization size segments for each market; (iv) applying final size segment investability requirements; and (v) applying index continuity rules for the MSCI Global Standard Index.

Defining the Equity Universe. MSCI begins with securities listed in countries in the MSCI GIMI. Of these countries, as of August 31, 2011, 24 are classified as developed markets, 21 as emerging markets, and 31 as frontier markets. All listed equity securities and listed securities that exhibit characteristics of equity securities, except mutual funds, ETFs, equity derivatives, limited partnerships and most investment trusts, are eligible for inclusion in the equity universe. REITs in some countries and certain income trusts in Canada are also eligible for inclusion. Each company and its securities (i.e., share classes) are classified in only one country.

Determining the Market Investable Equity Universe for each Market. The equity universe in any market is derived by applying investability screens to individual companies and securities in the equity universe of that market. Some investability requirements are applied at the individual security level and some at the overall company level, represented by the aggregation of individual securities of the company. As a result, the inclusion or exclusion of one security does not imply the automatic inclusion or exclusion of other securities of the same company.

Determining Market Capitalization Size Segments for each Market. In each market, MSCI creates an Investable Market Index, Standard Index, Large Cap Index, Mid Cap Index and Small Cap Index. The MSCI Global Standard Index is the aggregation of the Large Cap Index and Mid Cap Index. The MSCI GIMI is the aggregation of the MSCI Global Standard Index and MSCI Global Small Cap Index. In order to create size components that can be meaningfully aggregated into composites, individual market size segments balance the following two objectives:

  • Achieving global size integrity by ensuring that companies of comparable and relevant sizes are included in a given size segment across all markets in a composite index; and
  • Achieving consistent market coverage by ensuring that each market’s size segment is represented in its proportional weight in the composite universe.

Applying Final Size Segment Investability Requirements. In order to enhance replicability of the indexes, additional size segment investability requirements are set for the MSCI GIMI and MSCI Global Standard Index. These investability requirements include minimum free float market capitalization, minimum liquidity, minimum foreign limits and minimum length of trading.

Applying Index Continuity Rules for the Standard Index. In order to achieve index continuity as well as provide some basic level of diversification within a market index, notwithstanding the effect of other index construction rules contained herein, a minimum number of five constituents will be maintained for a developed market Standard Index and a minimum number of three constituents will be maintained for an emerging market Standard Index.

Weighting. All indexes of the MSCI GIMI are free-float weighted, i.e., companies are included in the indexes at the value of their free public float (free float multiplied by security price).

Regional Weights. Market capitalization weighting, combined with a consistent target of approximately 99% of free-float adjusted market capitalization, helps ensure that each country’s weight in regional and international indexes approximates its weight in the total universe of developing and emerging markets. A market is equivalent to a single country except for Europe, where all markets are aggregated into a single market for index construction purposes. Individual country indexes of the European developed markets are derived from the constituents of the MSCI GIMI Europe Index.

Free Float. MSCI defines the free float of a security as the proportion of shares outstanding that are deemed to be available for purchase in the public equity markets by international investors. In practice, limitations on free float available to international investors include: (i) strategic and other shareholdings not considered part of available free float; and (ii) limits on share ownership for foreigners.

Under MSCI’s free-float adjustment methodology, a constituent’s inclusion factor is equal to its estimated free float rounded-up to the closest 5% for constituents with free float equal to or exceeding 15%. For example, a constituent security with a

free float of 23.2% will be included in the index at 25% of its market capitalization. For securities with a free float of less than 15%, the estimated free float is adjusted to the nearest 1%.

Price and Exchange Rates

Prices. The prices used to calculate all MSCI indexes are the official exchange closing prices or those figures accepted as such. MSCI reserves the right to use an alternative pricing source on any given day.

Exchange Rates. Since July 2000, MSCI uses the WM/Reuters Closing Spot Rates taken at 4:00 p.m. London time. In case WM/Reuters does not provide rates for specific markets on given days (for example, Christmas Day and New Year’s Day), the previous business day’s rates are normally used. MSCI independently monitors the exchange rates on all its indices. MSCI may under exceptional circumstances elect to use alternative sources of exchange rates if the WM/Reuters rates are not available, or if MSCI determines that the WM/Reuters rates are not reflective of market circumstances for a given currency on a particular day. In such circumstances, an announcement would be sent to clients with the related information. If appropriate, MSCI may conduct a consultation with the investment community to gather feedback on the most relevant exchange rate.

Changes to the Indexes. The MSCI GIMI is maintained with the objective of reflecting, on a timely basis, the evolution of the underlying equity markets. In maintaining the MSCI indexes, emphasis is also placed on continuity, replicability and minimizing turnover in the indexes. Maintaining the MSCI indexes involves many aspects, including (i) additions to, and deletions from, the indexes; (ii) changes in number of shares; and (iii) changes in inclusion factors as a result of updated free float estimates.

Index maintenance can be described by three broad categories of changes:

  • Semi-Annual Index Reviews (“SAIRs”), conducted on a fixed semi-annual timetable that systematically reassess the various dimensions of the equity universe for all markets;
  • Quarterly Index Reviews (“QIRs”), aimed at promptly reflecting other significant market events; and
  • Ongoing event-related changes, such as mergers, acquisitions, spin-offs, bankruptcies, reorganizations and other similar corporate events, which generally are implemented in the indexes as they occur.

Potential changes in the status of countries (stand-alone, frontier, emerging and developed) follow their own implementation time tables.

MSCI conducts SAIRs generally as of the close of the last business day of May and November. During the SAIRs, MSCI updates the investable equity universe and reassesses size segmentation investability requirements. MSCI also conducts QIRs generally as of the close of the last business day of February and August. During the QIRs, MSCI reflects changes in the index that were not captured at the time of their actual occurrence, but are significant enough to be included before the next SAIR. The results of the SAIR and QIR are generally announced at least ten business days in advance of implementation.

MSCI EAFE® Growth Index

Number of Components: approximately 541

Index Description. The MSCI EAFE® Growth Index is a subset of the MSCI EAFE® Index and constituents of the Underlying Index include securities from Europe, Australasia and the Far East. The Underlying Index generally represents approximately 50% of the free float-adjusted market capitalization of the MSCI EAFE® Index and consists of those securities classified by MSCI as most representing the growth style. Securities classified as growth style generally tend to have higher forecasted growth rates, lower book value to price ratios, lower forward earnings to price ratios and lower dividend yields than securities representing the value style. MSCI uses a specialized framework to attribute both growth and value style characteristics to each security within the MSCI EAFE® Index. Each security is evaluated based on certain value factors and growth factors, which are then used to calculate a growth score and value score. Based upon these two scores, MSCI determines the extent to which each security is assigned to the growth or value style. It is possible for a single security to have representation in both the growth and value style indexes, however, no more than 100% of a security’s float-adjusted market capitalization will be included within the combined style framework.

The NYSE Indexes

Component Selection Criteria. The NYSE Indexes track the performance of specified New York Stock Exchange (“NYSE”) listed securities. The Indexes are maintained according to a rules-based methodology. The Indexes are capitalization-weighted, adjusted for free-float shares and calculated on a price and total return basis. The Indexes are weighted by float-adjusted market capitalization, rather than full market capitalization, in order to better reflect the actual number of shares available to investors. The Indexes are published every business day, and real-time updates are disseminated to financial data vendors whenever the NYSE is open.

Issue Changes. The weightings of securities (i.e., “components”) in each Index are reviewed quarterly based on market capitalization and free-float data (with the exception of the NYSE Composite, NYSE Energy, NYSE Financial and NYSE Health Care Indexes, each of which is rebalanced on an ongoing basis). All index-component companies must meet the substantive listing requirements of the NYSE; components that fail to meet such requirements are dropped from the Indexes. Quarterly reviews are implemented during March, June, September, and December. Changes in index composition and related weight may also be necessary on an ongoing basis to reflect extraordinary events such as delistings, bankruptcies, mergers or takeovers involving index components and changes of more than 10% in the number of outstanding shares of an Index.

Index Maintenance. Index maintenance includes monitoring and implementing the adjustments for component additions and deletions, share changes, stock splits, stock dividends, corporate restructurings, spin-offs, or other corporate actions. Some corporate actions, such as stock splits and stock dividends, require simple changes in the common shares outstanding and the stock prices of the component companies in the Index. Other corporate actions, such as share issuances, change the aggregate free-float adjusted market capitalization of the Indexes and require additional adjustments. Corporate actions will be implemented after the close of trading on the day prior to the ex-date of such corporate actions. Whenever possible, changes to the Indexes’ components will be announced at least two business days prior to their implementation date.

If trading in a security is suspended while the NYSE is open, the last traded price for that security on the NYSE is used for all subsequent index computations until trading resumes. If trading is suspended before the opening of the NYSE on a given day, the security’s adjusted closing price from the previous day is used to calculate the Index. Until a particular security opens, its adjusted closing price from the previous day is used in the Index computation.

Index Availability. The NYSE Indexes are calculated continuously and are available from major data vendors.

NYSE Composite Index

Number of Components: approximately 1,863

Index Overview and Description. The NYSE Composite Index is weighted using free-float market capitalization, and calculated on both price (i.e., real time) and total return (i.e., end of trading day) basis. The composition of the Underlying Index is transparent and rule-based. The Underlying Index is calculated and maintained by Dow Jones Indexes pursuant to a contractual agreement with the NYSE.

Methodology. Only common stocks, ADRs, REITs and tracking stocks listed on the NYSE are eligible for inclusion in the Underlying Index. Multiple classes of shares of the same issuer are eligible to be included in the Underlying Index. Preferred stocks, closed-end funds, ETFs, trust units, shares of beneficial interest, shares in limited partnerships, and derivative securities (such as warrants and rights) are not eligible for inclusion in the Underlying Index.

Calculation and Dissemination. The Underlying Index is calculated whenever the NYSE is open using the latest traded price on the NYSE for each security in the Underlying Index. Following the determination of the previous day’s closing Underlying Index value, the Underlying Index values for the current day are updated and disseminated following the opening of NYSE trading on a real-time basis beginning when the first traded price of any of the Underlying Index components are received.

Weighting. The Underlying Index is weighted by float-adjusted market capitalization, rather than full market capitalization, to reflect the actual number of shares available to investors. Shares held by governments, corporations, strategic partners of the issuer and control groups are excluded from an issuer’s available float when determining Underlying Index weightings.

NYSE U.S. 100 Index

Number of Components: 100

Index Overview and Description. The NYSE U.S. 100 Index is designed to measure the performance of the largest 100 U.S. companies, based on market capitalizaton, listed on the NYSE. The Underlying Index is weighted using free-float market capitalization and is calculated on both price (i.e., real-time) and total return (i.e., end of trading day) basis. The composition of the Underlying Index is transparent and rule-based. The Underlying Index is calculated and maintained by Dow Jones Indexes pursuant to a contractual agreement with NYSE.

Methodology. Only common stocks and other securities that have the characteristics of common equities of U.S. companies listed on the NYSE are eligible for inclusion in the Underlying Index. Fixed-dividend shares and securities such as convertible notes, warrants, rights, mutual funds, unit investment trusts, closed-end fund shares, shares in limited partnerships and tracking stocks are not eligible for inclusion in the Underlying Index. Companies that have less than 100,000 shares in average daily trading volume for the preceding three months are ineligible for inclusion in the Underlying Index. If a company has multiple share classes, only the class of shares that has the highest average daily trading volume during the preceding three months is included in the Underlying Index.

Calculation and Dissemination. The Underlying Index is calculated whenever the NYSE is open using the latest traded price on the NYSE for each security in the Underlying Index. Following the determination of the previous day’s closing Underlying Index value, the Underlying Index values for the current day are updated and disseminated following the opening of NYSE trading on a real-time basis, beginning when the first traded price of any of the Underlying Index components are received.

Weighting. The Underlying Index is weighted by float-adjusted market capitalization, rather than full market capitalization, to reflect the actual number of shares available to investors. Shares held by governments, corporations, strategic partners of the issuer and other control groups are excluded from a company’s available float when determining Underlying Index weightings.

Index Maintenance. The Underlying Index is rebalanced quarterly, with an “80-120” buffer applied to limit turnover. When the eligible universe is ranked by market capitalization, all stocks (components and new components) in the top 80 are automatically included in the Underlying Index while all stocks ranked below 120, including prior components, are automatically excluded. The remaining components are selected from stocks falling between 80 and 120, starting with the highest ranked prior components. If all prior components in this group have been added to the Underlying Index and spaces are still left, new components are added, starting with the largest capitalization stocks. Initial public offerings (“IPOs”) and new listings are eligible for inclusion at the quarterly rebalancing following their sale or listing, provided that their market

capitalization and trading volumes have met the threshold for inclusion for at least five trading days. However, if an IPO company or new listing would be in the top 25% of the Underlying Index’s market capitalization, it may be included between reviews, provided that a minimum notification period of two business days is observed.

In addition to the scheduled quarterly rebalancing, the Underlying Index is rebalanced on an ongoing basis to accommodate extraordinary events, such as delistings, bankruptcies, mergers and acquisitions and changes of more than 10% in the number of outstanding shares of an Underlying Index component.

The PHLX Semiconductor Sector Index1

Number of Components: approximately 30

Index Description. The PHLX Semiconductor Sector Index is designed to track the performance of U.S. traded securities of a set of companies engaged in the design, distribution, manufacture, and sale of semiconductors.

Index Calculation. The PHLX Semiconductor Index is a modified capitalization-weighted index. The value of the Index equals the aggregate value of the Index share weights, also known as the Index Shares, of each of the Index Securities multiplied by each such security’s Last Sale Price2 , and divided by the divisor of the Index. The divisor serves the purpose of scaling such aggregate index value to a lower order of magnitude which is more desirable for reporting purposes. If trading in an Index Security is halted on its primary listing market, the most recent Last Sale Price is used for all index computations until trading on such market resumes. Likewise, the most recent Last Sale Price is used if trading in a security is halted on its primary listing market before the market is open. The Index began on December 1, 1993 at a base value of 100.00, as adjusted.

The formula for index value is as follows:

  • Aggregate Adjusted Market Value/Divisor

The formula for the divisor is as follows:

  • (Market Value after Adjustments/Market Value before Adjustments) X Divisor before Adjustments
Two versions of the Index are calculated – a price return index and a total return index. The price return index (NASDAQ: SOX) is ordinarily calculated without regard to cash dividends on Index Securities. The total return index (NASDAQ: XSOX) reinvests cash dividends on the ex-date. Both Indexes reinvest extraordinary cash distributions. The total return index was synchronized to the value of the price return index at the close on December 22, 2009. The Index is calculated during the trading day and is disseminated once per second from 09:30:01 to 17:16:00 ET. The closing value of the Index may change up until 17:15:00 ET due to corrections to the Last Sale Price of the Index Securities.

Initial Security Eligibility Criteria. Index eligibility is limited to specific security types only. The security types eligible for the Index include common stocks, ordinary shares, ADRs, shares of beneficial interest or limited partnership interests and tracking stocks. Security types not included in the Index are closed-end funds, convertible debentures, exchange traded funds, preferred stocks, rights, warrants, units and other derivative securities.

To be eligible for inclusion in the Index, a security must meet the following criteria:

  • a security must be listed on NASDAQ, the NYSE, or NYSE Amex;
  • the issuer of the security must be classified, as reasonably determined by NASDAQ OMX, as a company whose primary business is involved in the design, distribution, manufacture, and sale of semiconductors;
  • only one class of security per issuer is allowed;
  • the security must have a market capitalization of at least $100 million;
  • the security must have traded at least 1.5 million shares in each of the last six months;
  • the security must have listed options on a recognized options market in the U.S. or be eligible for listed-options trading on a recognized options market in the U.S.;
  • the security may not be issued by an issuer currently in bankruptcy proceedings;
  • the issuer of the security may not have entered into a definitive agreement or other arrangement which would likely result in the security no longer being Index eligible;
  • the issuer of the security may not have annual financial statements with an audit opinion that is currently withdrawn; and
  • the issuer of the security must have been “seasoned” on a recognized market for at least 6 months; in the case of spin-offs, the operating history of the spin-off will be considered.

Continued Security Eligibility Criteria. To be eligible for continued inclusion in the Index, an Index Security must meet the following criteria:

  • a security must be listed on NASDAQ, the NYSE, or NYSE Amex;
  • the issuer of the security must be classified, as reasonably determined by NASDAQ OMX, as a company whose primary business is involved in the design, distribution, manufacture, and sale of semiconductors (Index Securities as of October 31, 2008, will be grandfathered for Index classification purposes, unless there is a material change in its business line);
  • the security must have a market capitalization of at least $60 million;
  • the security may not be issued by an issuer currently in bankruptcy proceedings; and
  • the issuer of the security may not have annual financial statements with an audit opinion that is currently withdrawn.

Component Replacement Criteria. In the event that an Index Security no longer meets the Continued Security Eligibility Criteria, it is replaced with a security that is not currently in the index that meets all of the Initial Security Eligibility Criteria and additional criteria which follows. Securities eligible for inclusion are ranked ascending by market value, current price and percentage price change over the previous six months (the “Ranking Process”). The security with the highest overall ranking is added to the Index (with largest market capitalization determining inclusion if multiple securities have the same rank) provided that the Index then meets the following criteria:

  • no single Index Security is greater than 20% of the weight of the Index and the top five Index Securities are not greater than 55% of the weight of the Index; and
  • no more than 15% of the weight of the Index is composed of non-U.S. component securities that are not subject to comprehensive surveillance agreements.

In the event that the highest ranking security does not permit the Index to meet the above Component Replacement Criteria, the next highest-ranking security is selected and the criteria will again be applied to determine eligibility. The process continues until a qualifying replacement security is selected.

Continued Index Eligibility Criteria. In addition to the security eligibility criteria, the Index as a whole must meet the following criteria on a continual basis unless otherwise noted:

  • no single Index Security is greater than 25% of the weight of the Index and the top five Index Securities are not greater than 60% of the weight of the Index (measured semi-annually as of the first trading day in January and July);
  • no more than 18% of the weight of the Index is composed of non-U.S. Index Securities that are not subject to comprehensive surveillance agreements;
  • the total number of Index Securities has not increased or decreased by 33 1/3% of the Index and in no event will be less than nine;
  • Index Securities representing at least 95% of the weight of the Index has a market capitalization of $75 million;
  • Index Securities representing at least 92% of the weight of the Index and at least 82% of the total number of Index Securities meet the security options eligibility rules;
  • Index Securities must have trading volume of at least 600,000 shares for each of the last six months except that for each of the lowest weighted Index Securities that in the aggregate account for no more than 5% of the weight of the Index, trading volume must be at least 500,000 shares for each of the last six months; and
  • the lesser of the five highest weighted Index Securities or the highest weighted Index Securities that in the aggregate represent at least 30% of the total number of Index Securities each have had an average monthly trading volume of at least 1,250,000 shares over the past six months.

In the event the Index does not meet the continued eligibility criteria, the Index composition will be adjusted to ensure that the Index meets the criteria. Index Securities that contribute to the Index not meeting the eligibility criteria may be removed. Index Securities may be added and/or replaced according to the Component Replacement Criteria to ensure compliance with the Index Continued Eligibility Criteria. Ordinarily, a security will be removed from the Index at its Last Sale Price. If, however, at the time of its removal the Index Security is halted from trading on its primary listing market and an official closing price cannot be readily be determined, the Index Security may, in NASDAQ’s discretion, be removed at a zero price. The zero price will be applied to the Index Security after the close of the market but prior to the time the official closing value of the Index is disseminated, which is ordinarily 17:16:00 ET.

Index Maintenance. Changes in the price and/or Index Shares driven by corporate events such as stock dividends, stock splits and certain spin-offs and rights issuances are adjusted on the ex-date. If the change in total shares outstanding arising from other corporate actions is greater than or equal to 10.0%, the change is made as soon as practicable. (If a security is a depositary receipt, the total shares outstanding is the actual depositary shares outstanding as reported by the depositary banks.) Otherwise, if the change in total shares outstanding is less than 10%, then all such changes are accumulated and made effective at one time on a quarterly basis after the close of trading on the third Friday in each of March, June, September and December. The Index Shares are derived from the security’s total shares outstanding. Intraquarter, the Index Shares are adjusted by the same percentage amount by which the total shares outstanding have changed.

In the case of a special cash dividend, a determination is made on an individual basis whether to make a change to the price of an Index Security in accordance with its Index dividend policy. If it is determined that a change will be made, it will become effective on the ex-date.

Ordinarily, whenever there is a change in Index Shares, a change in an Index Security, or a change to the price of an Index Security due to spin-offs, rights issuances or special cash dividends, the divisor is adjusted to ensure that there is no discontinuity in the value of the Index which might otherwise be caused by any such change. All changes are announced in advance and are reflected in the Index prior to market open on the Index effective date.

Index Rebalancing. The Index employs a modified market capitalization-weighting methodology. At each quarter, the Index is rebalanced such that the maximum weight of any Index Security does not exceed 8% and no more than 5 securities are at that cap. The excess weight of any capped security is distributed proportionally across the remaining Index Securities. If after redistribution, any of the five highest ranked Index Securities are weighted below 8%, these securities are not capped. Next, any remaining Index Securities in excess of 4% are capped at 4% and the excess weight is redistributed proportionally across the remaining Index Securities. The process is repeated, if necessary, to derive the final weights.

The modified market capitalization-weighting methodology is applied to the capitalization of each Index Security, using the Last Sale Price of the security at the close of trading on the last trading day in February, May, August and November and after applying quarterly changes to the total shares outstanding. Index Shares are then calculated multiplying the weight of the security derived above by the new market value of the Index and dividing the modified market capitalization for each Index Security by its corresponding Last Sale Price. The changes are effective after trading on the third Friday in March, June, September and December.

In administering the Index, NASDAQ OMX will exercise reasonable discretion as it deems appropriate to ensure Index integrity.

Index Availability. The PHLX Semiconductor Sector Index is calculated continuously and widely disseminated to major data vendors.


1 Effective October 15, 2010, the iShares PHLX SOX Semiconductor Sector Index Fund’s Underlying Index changed from S&P North American Technology-Semiconductors Index to PHLX Semiconductor Sector Index.
2 For a security listed on NASDAQ, it is the last sale price on NASDAQ, which normally would be the Nasdaq Official Closing Price (NOCP) when NASDAQ is closed. For any NYSE-listed or NYSE Amex-listed security, it is the last regular way trade reported on such such security’s primary U.S. listing market. If a security does not trade on its primary listing market on a given day, the most recent last sale price from the primary listing market (adjusted for corporate actions, if any) is used.

The S&P Indexes

Component Selection Criteria for Domestic Indexes. The Standard & Poor’s Index Committee is responsible for the overall management of the S&P Indexes. Issuers (i.e., the “components”) selected for the S&P U.S. Indexes represent a broad range of industry segments within the U.S. economy. The starting universe of publicly traded U.S. issuers classified by the Global Industry Classification Standard (GICS® ) is screened to eliminate ADRs, mutual funds, limited partnerships, royalty trusts, certain holding issuers, OTC bulletin board issues, pink sheet-listed issues, closed-end funds, ETFs and tracking stocks. REITs, except for mortgage REITs, are eligible for inclusion in the Indexes. The stock of each constituent must trade on either the NYSE, the American Stock Exchange (“AMEX”) or on NASDAQ. Additionally, only one share class per constituent will be included in an Index. The share class is selected by S&P and is generally defined as the largest, most liquid share class. Issuers with multiple share classes will have the classes combined for purposes of calculation of market capitalization. The following criteria are then analyzed to determine an issuer’s eligibility for inclusion in the S&P Indexes: (i) ownership of an issuer’s outstanding common stock, in order to screen out closely held issuers; (ii) trading volume of an issuer’s shares, in order to ensure ample liquidity and efficient share pricing; and (iii) the financial and operating condition of an issuer.

The S&P Indexes are capitalization weighted, based on the following formula: number of outstanding shares of a constituent (as determined by the float-adjusted market capitalization using S&P’s methodology) multiplied by the constituent’s share price. Issuers with float-adjusted market capitalizations below certain thresholds are not eligible for the Indexes. In addition, the market capitalization of an issuer eligible for inclusion must be equal or greater than the Index’s minimum market capitalization at the time it is being considered for Index inclusion. The market capitalizations of an Index’s constituents are adjusted to reflect changes in capitalization resulting from mergers, acquisitions, stock rights, substitutions and other capital events. The market capitalizations of an Index’s constituent are adjusted for all strategic holdings, including private, corporate, and government holdings.

Additional Component Selection Criteria for S&P North American Sector Indexes. To be eligible for the S&P North American Indexes, issuers must be a member of either the S&P Total Market Index (TMI) or the S&P/Toronto Stock Exchange (“TSX”) Composite. The S&P North American Sector Indexes are modified market capitalization weighted. After S&P calculates the float-adjusted market capitalizations, weights are modified so that no single constituent exceeds limits predetermined by S&P. If the combined weight of all the constituents with an individual weight greater than 5% exceeds a certain amount determined by S&P, then S&P reduces the weightings of such stocks in accordance with its methodology. Each index constituent can be a member of one, and only one, S&P North American Sector Index.
The S&P North American Sector Indexes are rebalanced semiannually on the third Friday of June and December. Except for major corporate actions such as mergers and spin-offs, stocks can only be added to or deleted from an Index at the time of the semi-annual rebalancing. In the case of GICS changes, where an issuer does not belong to a qualifying sector after the classification change, the issuer is removed from the relevant Index at the next rebalancing.

Component Selection Criteria for International Indexes. Stocks are eligible for the S&P Global Indexes if they meet criteria for size, liquidity, profitability, and sector and market representation. Each of the S&P Global Indexes is balanced across country and sector weights in the region/market. The S&P Global Indexes begin with an eligible investable universe of stocks covering approximately 95% of each country’s total market capitalization. In some cases, the S&P Global Indexes may include ADRs and GDRs. Stocks with relatively small market capitalization or insufficient liquidity are excluded by S&P. To identify a candidate pool for index constituent selection, all stocks are carefully examined using a set of general criteria. The specific securities are then screened for industry sector classification; thus, the eligible securities are ranked according to GICS. Then, the Index components, now determined, are weighted on the basis of S&P’s float-adjusted, market capitalization methodology. Generally, S&P observes a prospective constituent’s liquidity over a period of at least six months before consideration for inclusion. However, there may be extraordinary situations when issuers should be added immediately (e.g., certain privatizations). When a particular issuer dominates its home market, it may be excluded from an Index if analysis of the sectors reveals that its securities are not as liquid as those of similar issuers in other countries. Once a year, the float adjustments will be reviewed and potentially changed based on such review. The values of an Index’s constituents are adjusted to reflect changes in capitalization resulting from mergers, acquisitions, stock rights, substitutions and other capital events. The market capitalization of index constituent issuers is adjusted for all strategic holdings, including private, corporate, and government holdings.

With respect to the non-U.S. components of the S&P Global Indexes, the eligible universe of index components that are considered for inclusion are from the following S&P Indexes: (i) the TSX 60 Index, which represents the liquid, large-cap

stocks of the publicly listed issuers in the Canadian equities market; (ii) the S&P Tokyo Stock Price (“TOPIX”) 150 Index which represents the liquid, large-cap stocks of the publicly-listed issuers in the Japanese equities market; (iii) the S&P/Australia Stock Exchange (“ASX”) All-Australian 50 Index, which represents the liquid, large-cap stocks in the Australian equities market; (iv) the S&P Asia 50 Index, which represents the liquid, large-cap stocks of four major equities markets in Asia (Hong Kong, South Korea, Taiwan and Singapore); (v) the S&P Latin America 40 Index, which represents the liquid, large-cap stocks from major sectors of the Mexico, Brazil, Peru and Chilé equity markets; and (vi) the S&P Europe 350 Index, which represents the liquid, large-cap stocks of the publicly listed issuers in the region, covering approximately 70% of the region’s market capitalization.

Issue Changes. General oversight responsibility for the S&P Indexes, including overall policy guidelines and methodology, is handled by the S&P Global Index Committee. Maintenance of component investments, including additions and deletions to these investments, is the responsibility of separate regional index committees composed of S&P staff specialized in the various regional equity markets and, in some cases, with the assistance of local stock exchanges. Public announcements of index changes as the result of committee decisions will generally be made two business days in advance of the anticipated effective date whenever possible, although for exceptional corporate events announcements may be made earlier.

Index Maintenance. Maintaining the S&P Indexes includes monitoring and completing the adjustments for issuer additions and deletions, share changes, stock splits, stock dividends, and stock price adjustments due to restructuring and spin-offs. An issuer will be removed from the S&P Indexes as a result of mergers/acquisitions, bankruptcy, or restructuring. An issuer is removed from the relevant index as close as possible to the actual date on which the event occurred. An issuer can be removed from an index because it no longer meets current criteria for inclusion and/or is no longer representative of its industry group. All replacement issuers are selected based on the above component section criteria.

When calculating index weights, individual constituents’ shares held by governments, corporations, strategic partners, or other control groups are excluded from the issuer’s shares outstanding. Shares owned by other issuers are also excluded regardless of whether they are index constituents.

In countries with regulated environments, where a foreign investment limit exists at the sector or issuer level, the constituent’s weight will reflect either the foreign investment limit or the percentage float, whichever is the more restrictive.

Each issuer’s financial statements will be used to update the major shareholders’ ownership. However, during the course of the year, S&P also monitors each issuer’s Investable Weight Factor (“IWF”) which is S&P’s term for the mathematical float factor used to calculate the float adjustment. If a change in IWF is caused by a major corporate action (i.e., privatization, merger, takeover, or share offering) and the change equal to or greater than 5%, a float adjustment will be implemented as soon as reasonably possible.

Changes in the number of shares outstanding driven by corporate events such as stock dividends, splits, and rights issues will be adjusted on the ex-date. Share changes of 5% or greater are implemented when they occur. Share changes of less than 5% are only updated on a quarterly basis on the Friday near the end of the calendar quarter. Generally, index changes due to rebalancing are announced two days before the effective date by way of a news release posted on www.indices.standardandpoors.com.

Index Availability. The S&P Indexes are calculated continuously and are available from major data vendors.

Investment Limitations

Each Fund has adopted its investment objective as a non-fundamental investment policy. Therefore, each Fund may change its investment objective and its Underlying Index without shareholder approval. The Board has adopted as fundamental policies the following numbered investment restrictions, which cannot be changed without the approval of the holders of a majority of the applicable Fund’s outstanding voting securities. A vote of a majority of the outstanding voting securities is defined in the 1940 Act as the lesser of (a) 67% or more of the voting securities present at a fund meeting, if the holders of more than 50% of the outstanding voting securities are present or represented by proxy and (b) more than 50% of outstanding voting securities of the fund.

All Funds (other than the iShares FTSE China 25 Index Fund, iShares FTSE China (HK Listed) Index Fund, iShares FTSE Developed Small Cap ex-North America Index Fund, iShares MSCI ACWI ex US Consumer Discretionary Sector Index Fund, iShares MSCI ACWI ex US Consumer Staples Sector Index Fund, iShares MSCI ACWI ex US Energy Sector Index Fund, iShares MSCI ACWI ex US Financials Sector Index Fund, iShares MSCI ACWI ex US Health Care Sector Index Fund, iShares MSCI ACWI ex US Index Fund, iShares MSCI ACWI ex US Industrials Sector Index Fund, iShares MSCI ACWI ex US Information Technology Sector Index Fund, iShares MSCI ex US Materials Sector Index Fund, iShares MSCI ACWI ex US Telecommunication Services Sector Index Fund, iShares MSCI ACWI ex US Utilities Sector Index Fund, iShares MSCI ACWI Index Fund, iShares MSCI EAFE Small Cap Index Fund, iShares MSCI Emerging Markets Financials Sector Index Fund, iShares MSCI Emerging Markets Materials Sector Index Fund, iShares MSCI Europe Financials Sector Index Fund, iShares MSCI Far East Financials Sector Index Fund, iShares NYSE 100 Index Fund and iShares S&P North American Technology-Multimedia Networking Index Fund) will not:

1. Concentrate its investments (i.e., hold 25% or more of its total assets in the stocks of a particular industry or group of industries), except that each Fund will concentrate to approximately the same extent that its Underlying Index concentrates in the stocks of such particular industry or group of industries. For purposes of this limitation, securities of the U.S. government (including its agencies and instrumentalities), repurchase agreements collateralized by U.S. government securities, and securities of state or municipal governments and their political subdivisions are not considered to be issued by members of any industry.
2. Borrow money, except that (i) each Fund may borrow from banks for temporary or emergency (not leveraging) purposes, including the meeting of redemption requests which might otherwise require the untimely disposition of securities, and (ii) each Fund may, to the extent consistent with its investment policies, enter into repurchase agreements, reverse repurchase agreements, forward roll transactions and similar investment strategies and techniques. To the extent that it engages in transactions described in (i) and (ii), each Fund will be limited so that no more than 33 1/3% of the value of its total assets (including the amount borrowed) is derived from such transactions. Any borrowings which come to exceed this amount will be reduced in accordance with applicable law.
3. Issue any senior security, except as permitted under the 1940 Act, as amended, and as interpreted, modified or otherwise permitted by regulatory authority having jurisdiction, from time to time.
4. Make loans, except as permitted under the 1940 Act, as amended, and as interpreted, modified or otherwise permitted by regulatory authority having jurisdiction, from time to time.
5. Purchase or sell real estate, real estate mortgages, commodities or commodity contracts, but this restriction shall not prevent each Fund from trading in futures contracts and options on futures contracts (including options on currencies to the extent consistent with each Fund’s investment objective and policies).

6. Engage in the business of underwriting securities issued by other persons, except to the extent that each Fund may technically be deemed to be an underwriter under the 1933 Act, in disposing of portfolio securities.

Each of iShares FTSE China 25 Index Fund, iShares S&P North American Technology-Multimedia Networking Index Fund and iShares NYSE 100 Index Fund will not:

1. Concentrate its investments (i.e., hold 25% or more of its total assets in the stocks of a particular industry or group of industries), except that a Fund will concentrate to approximately the same extent that its Underlying Index concentrates in the stocks of such particular industry or group of industries. For purposes of this limitation, securities of the U.S. government (including its agencies and instrumentalities), repurchase agreements collateralized by U.S. government securities, and securities of state or municipal governments and their political subdivisions are not considered to be issued by members of any industry.
2. Borrow money, except that (i) each Fund may borrow from banks for temporary or emergency (not leveraging) purposes, including the meeting of redemption requests which might otherwise require the untimely disposition of securities, and (ii) each Fund may, to the extent consistent with its investment policies, enter into repurchase agreements, reverse repurchase agreements, forward roll transactions and similar investment strategies and techniques. To the extent that it engages in transactions described in (i) and (ii), each Fund will be limited so that no more than 33 1/3% of the value of its total assets (including the amount borrowed) is derived from such transactions. Any borrowings which come to exceed this amount will be reduced in accordance with applicable law.
3. Issue “senior securities” as defined in the 1940 Act and the rules, regulations and orders thereunder, except as permitted under the 1940 Act and the rules, regulations and orders thereunder.
4. Make loans. This restriction does not apply to: (i) the purchase of debt obligations in which each Fund may invest consistent with its investment objectives and policies; (ii) repurchase agreements and reverse repurchase agreements; and (iii) loans of its portfolio securities, to the fullest extent permitted under the 1940 Act.
5. Purchase or sell real estate, real estate mortgages, commodities or commodity contracts, but this restriction shall not prevent each Fund from trading in futures contracts and options on futures contracts (including options on currencies to the extent consistent with each Fund’s investment objective and policies).
6. Engage in the business of underwriting securities issued by other persons, except to the extent that each Fund may technically be deemed to be an underwriter under the 1933 Act in disposing of portfolio securities.

Each of iShares FTSE China (HK Listed) Index Fund, iShares FTSE Developed Small Cap ex-North America Index Fund, iShares MSCI ACWI ex US Consumer Discretionary Sector Index Fund, iShares MSCI ACWI ex US Consumer Staples Sector Index Fund, iShares MSCI ACWI ex US Energy Sector Index Fund, iShares MSCI ACWI ex US Financials Sector Index Fund, iShares MSCI ACWI ex US Health Care Sector Index Fund, iShares MSCI ACWI ex US Index Fund, iShares MSCI ACWI ex US Industrials Sector Index Fund, iShares MSCI ACWI ex US Information Technology Sector Index Fund, iShares MSCI ACWI ex US Materials Sector Index Fund, iShares MSCI ACWI ex US Telecommunication Services Sector Index Fund, iShares MSCI ACWI ex US Utilities Sector Index Fund, iShares MSCI ACWI Index Fund, iShares MSCI EAFE Small Cap Index Fund, iShares MSCI Emerging Markets Financials Sector Index Fund, iShares MSCI Emerging Markets Materials Sector Index Fund, iShares MSCI Europe Financials Sector Index Fund and iShares MSCI Far East Financials Sector Index Fund will not:

1. Concentrate its investments (i.e., invest 25% or more of its total assets in the securities of a particular industry or group of industries), except that a Fund will concentrate to approximately the same extent that its Underlying Index concentrates in the securities of such particular industry or group of industries. For purposes of this limitation, securities of the U.S. government (including its agencies and instrumentalities), repurchase agreements collateralized by U.S. government securities, and securities of state or municipal governments and their political subdivisions are not considered to be issued by members of any industry.
2. Borrow money, except that (i) each Fund may borrow from banks for temporary or emergency (not leveraging) purposes, including the meeting of redemption requests which might otherwise require the untimely disposition of securities; and (ii) each Fund may, to the extent consistent with its investment policies, enter into repurchase agreements, reverse repurchase agreements, forward roll transactions and similar investment strategies and techniques. To the extent that it engages in transactions described in (i) and (ii), each Fund will be limited so that no more than 33 1/3% of the value of its total assets (including the amount borrowed) is derived from such transactions. Any borrowings which come to exceed this amount will be reduced in accordance with applicable law.

3. Issue any senior security, except as permitted under the 1940 Act, as amended, and as interpreted, modified or otherwise permitted by regulatory authority having jurisdiction, from time to time.
4. Make loans, except as permitted under the 1940 Act, as interpreted, modified or otherwise permitted by regulatory authority having jurisdiction, from time to time.
5. Purchase or sell real estate unless acquired as a result of ownership of securities or other instruments (but this restriction shall not prevent each Fund from investing in securities of companies engaged in the real estate business or securities or other instruments backed by real estate or mortgages), or commodities or commodity contracts (but this restriction shall not prevent each Fund from trading in futures contracts and options on futures contracts, including options on currencies to the extent consistent with each Fund’s investment objective and policies).
6. Engage in the business of underwriting securities issued by other persons, except to the extent that each Fund may technically be deemed to be an underwriter under the 1933 Act, in disposing of portfolio securities.

In addition to the investment restrictions adopted as fundamental policies set forth above, each Fund has adopted a non-fundamental policy not to invest in the securities of a company for the purpose of exercising management or control or purchase or otherwise acquire any illiquid security, except as permitted under the 1940 Act, which currently permits up to 15% of each Fund’s net assets to be invested in illiquid securities (calculated at the time of investment).

BFA monitors the liquidity of restricted securities in each Fund’s portfolio. In reaching liquidity decisions, BFA considers the following factors:

  • The frequency of trades and quotes for the security;
  • The number of dealers wishing to purchase or sell the security and the number of other potential purchasers;
  • Dealer undertakings to make a market in the security; and
  • The nature of the security and the nature of the marketplace in which it trades (e.g., the time needed to dispose of the security, the method of soliciting offers and the mechanics of transfer).

If any percentage restriction described above is complied with at the time of an investment, a later increase or decrease in percentage resulting from a change in values of assets will not constitute a violation of such restriction, except that certain percentage limitations will be observed continuously in accordance with applicable law.

Each Fund has adopted a non-fundamental investment policy in accordance with Rule 35d-1 under the 1940 Act to invest, under normal circumstances, at least 80% of the value of its net assets, plus the amount of any borrowings for investment purposes, in securities of the Underlying Index or in Depositary Receipts representing securities in its Underlying Index. Each Fund also has adopted a policy to provide its shareholders with at least 60 days’ prior written notice of any change in such policy. If, subsequent to an investment, the 80% requirement is no longer met, a Fund’s future investments will be made in a manner that will bring the Fund into compliance with this policy.

Each of iShares MSCI EAFE Index Fund, iShares MSCI EAFE Small Cap Index Fund and iShares S&P North American Natural Resources Sector Index Fund has adopted a non-fundamental investment policy such that each Fund may invest in shares of other open-end management investment companies or unit investment trusts subject to the limitations of Section 12(d)(1) of the 1940 Act, including the rules, regulations and exemptive orders obtained thereunder; provided, however, that if the Fund has knowledge that its shares are purchased by another investment company investor in reliance on the provisions of subparagraphs (G) or (F) of Section 12(d)(1) of the 1940 Act, the Fund will not acquire any securities of other open-end management investment companies or unit investment trusts in reliance on the provisions of subparagraphs (G) or (F) of Section 12(d)(1) of the 1940 Act.

Continuous Offering

The method by which Creation Units are created and traded may raise certain issues under applicable securities laws. Because new Creation Units are issued and sold by the Funds on an ongoing basis, at any point a “distribution,” as such term is used in the 1933 Act, may occur. Broker-dealers and other persons are cautioned that some activities on their part may, depending on the circumstances, result in their being deemed participants in a distribution in a manner that could render them statutory underwriters and subject them to the prospectus delivery requirement and liability provisions of the 1933 Act.

For example, a broker-dealer firm or its client may be deemed a statutory underwriter if it takes Creation Units after placing an order with the Distributor, breaks them down into constituent shares and sells such shares directly to customers or if it chooses to couple the creation of new shares with an active selling effort involving solicitation of secondary market demand for shares. A determination of whether one is an underwriter for purposes of the 1933 Act must take into account all the facts and circumstances pertaining to the activities of the broker-dealer or its client in the particular case and the examples mentioned above should not be considered a complete description of all the activities that could lead to a categorization as an underwriter.

Broker-dealer firms should also note that dealers who are not “underwriters” but are effecting transactions in shares, whether or not participating in the distribution of shares, generally are required to deliver a prospectus. This is because the prospectus delivery exemption in Section 4(3) of the 1933 Act is not available in respect of such transactions as a result of Section 24(d) of the 1940 Act. Firms that incur a prospectus delivery obligation with respect to shares of the Funds are reminded that, pursuant to Rule 153 under the 1933 Act, a prospectus delivery obligation under Section 5(b)(2) of the 1933 Act owed to an exchange member in connection with a sale on the Listing Exchange is satisfied by the fact that the prospectus is available at the Listing Exchange upon request. The prospectus delivery mechanism provided in Rule 153 is available only with respect to transactions on an exchange.

Management

Trustees and Officers. The Board has responsibility for the overall management and operations of the Funds, including general supervision of the duties performed by BFA and other service providers. Each Trustee serves until he or she resigns, is removed, dies, retires or becomes incapacitated. The President, Chief Compliance Officer, Treasurer and Secretary shall each hold office until their successors are chosen and qualified, and all other officers shall hold office until he or she resigns or is removed. Trustees who are not interested persons (as defined in the 1940 Act) are referred to as Independent Trustees.

The registered investment companies advised by BFA or its affiliates are organized into one complex of closed-end funds, two complexes of open-end funds and one complex of exchange-traded funds (“Exchange-Traded Fund Complex”) (each, a “BlackRock Fund Complex”). Each Fund is included in the BlackRock Fund Complex referred to as the Exchange-Traded Fund Complex. Each Trustee also serves as a Director of iShares, Inc. and a Director of iShares MSCI Russia Capped Index Fund, Inc. and, as a result, oversees a total of 229 funds within the Exchange-Traded Fund Complex. With the exception of Robert S. Kapito, the address of each Trustee and officer is c/o BlackRock, Inc., 400 Howard Street, San Francisco, CA 94105. The address of Mr. Kapito is c/o BlackRock, Inc., Park Avenue Plaza, 55 East 52nd Street, New York, NY 10055. The Board has designated George G.C. Parker as its Independent Chairman.

The Board has concluded that, based on each Trustee’s experience, qualifications, attributes or skills on an individual basis and in combination with those of the other Trustees, each Trustee should serve as a Trustee of the Board. Among the attributes common to all Trustees are their ability to review critically, evaluate, question and discuss information provided to them, to interact effectively with the Funds’ investment adviser, other service providers, counsel and the independent registered public accounting firm, and to exercise effective business judgment in the performance of their duties as Trustees. A Trustee’s ability to perform his or her duties effectively may have been attained through the Trustee’s educational background or professional training; business, consulting, public service or academic positions; experience from service as a board member of the Funds and the other funds in the Trust (and any predecessor funds), other investment funds, public companies, or non-profit entities or other organizations; and/or other life experiences. Also, set forth below is a brief discussion of the specific experience, qualifications, attributes or skills of each Trustee that led the Board to conclude that he or she should serve as a Trustee.

Robert Kapito has been a Trustee of the Trust since 2009. Mr. Kapito has served as a Director of iShares, Inc. since 2009, a Director of iShares MSCI Russia Capped Index Fund, Inc. since 2010 and a Director of BlackRock, Inc. since 2007. In addition, he has over 20 years of experience as part of BlackRock, Inc. and BlackRock’s predecessor entities. Mr. Kapito serves as President and Director of BlackRock, Inc., and is the Chairman of the Operating Committee, a member of the Office of the Chairman, the Leadership Committee and the Corporate Council. He is responsible for day-to-day oversight of BlackRock’s key operating units, including the Account Management and Portfolio Management Groups, Real Estate Group and BlackRock Solutions® . Prior to assuming his current responsibilities in 2007, Mr. Kapito served as Head of BlackRock’s

Portfolio Management Group. In that role, he was responsible for overseeing all portfolio management within BlackRock, including the Fixed Income, Equity, Liquidity, and Alternative Investment Groups. Mr. Kapito serves as a member of the Board of Trustees of the University of Pennsylvania. He is also President of the Board of Directors for the Hope & Heroes Children’s Cancer Fund since 2002 and President of the Board of Directors for Periwinkle Theatre for Youth, a national non-profit arts-in-education organization, since 1983. Mr. Kapito earned a BS degree in economics from the Wharton School of the University of Pennsylvania in 1979, and an MBA degree from Harvard Business School in 1983.

Michael Latham has been a Trustee of the Trust since 2010 and President of the Trust since 2007. Mr. Latham served as Principal Financial Officer of the Trust from 2002 until 2007. Mr. Latham has served as a Director of iShares, Inc. since 2010, President of iShares, Inc. since 2007, Principal Financial Officer of iShares, Inc. from 2002 until 2007, a Director of iShares MSCI Russia Capped Index Fund, Inc. since 2010 and President of iShares MSCI Russia Capped Index Fund, Inc. since 2010. Mr. Latham is the Chairman of BlackRock’s iShares exchange-traded fund business. In addition, he has over 15 years of experience as part of BlackRock, Inc. and BlackRock’s predecessor entities. Prior to assuming his current responsibilities in September 2011, he was the global head of BlackRock’s iShares exchange-traded fund business.

Board – Leadership Structure and Oversight Responsibilities

Overall responsibility for oversight of the Funds rests with the Board. The Board has engaged BFA to manage the Funds on a day-to-day basis. The Board is responsible for overseeing BFA and other service providers in the operations of the Funds in accordance with the provisions of the 1940 Act, applicable provisions of state and other laws and the Trust’s charter. The Board is currently composed of nine members, seven of whom are Independent Trustees (defined below). The Board currently conducts regular meetings four times a year. In addition, the Board frequently holds special in-person or telephonic meetings or informal conference calls to discuss specific matters that may arise or require action between regular meetings. The Independent Trustees meet regularly outside the presence of management, in executive session or with other service providers to the Trust.

The Board has appointed an Independent Trustee to serve in the role of Chairman. The Chairman’s role is to preside at all meetings of the Board and to act as a liaison with service providers, officers, attorneys, and other Trustees generally between meetings. The Chairman may also perform such other functions as may be delegated by the Board from time to time. The Board has established a Nominating and Governance Committee and an Audit Committee to assist the Board in the oversight and direction of the business and affairs of the Funds, and from time to time may establish ad-hoc committees or informal

working groups to review and address the policies and practices of the Funds with respect to certain specified matters. The Board and each standing Committee conduct annual assessments of their oversight function and structure. The Board has determined that the Board’s leadership structure is appropriate because it allows the Board to exercise independent judgment over management and it allocates areas of responsibility among committees of Independent Trustees and the full Board to enhance effective oversight.

Day-to-day risk management with respect to the Funds is the responsibility of BFA or other service providers (depending on the nature of the risk), subject to the supervision of BFA. Each Fund is subject to a number of risks, including investment, compliance, operational and valuation risks, among others. While there are a number of risk management functions performed by BFA and other service providers, as applicable, it is not possible to eliminate all of the risks applicable to the Fund. The Trustees have an oversight role in this area, satisfying themselves that risk management processes are in place and operating effectively. Risk oversight forms part of the Board’s general oversight of each Fund and is addressed as part of various Board and committee activities. The Board, directly or through a committee, also reviews reports from, among others, management and the independent registered public accounting firm for the Trust, as appropriate, regarding risks faced by each Fund and management’s risk functions. The Board has appointed a Chief Compliance Officer who oversees the implementation and testing of the Trust’s compliance program and reports to the Board regarding compliance matters for the Trust and its principal service providers. In testing and maintaining the compliance program, the Chief Compliance Officer assesses key compliance risks affecting each Fund, and addresses them in reports to the Board. The Independent Trustees have engaged independent legal counsel to assist them in performing their oversight responsibilities.

Committees of the Board of Trustees. Each Trustee who is not an interested person (as defined in the 1940 Act) of the Trust (“Independent Trustee”) serves on the Audit Committee and the Nominating and Governance Committee of the Board. The purposes of the Audit Committee are to assist the Board (i) in its oversight of the Trust’s accounting and financial reporting principles and policies and related controls and procedures maintained by or on behalf of the Trust; (ii) in its oversight of the Trust’s financial statements and the independent audit thereof; (iii) in selecting, evaluating and, where deemed appropriate, replacing the independent accountants (or nominating the independent accountants to be proposed for shareholder approval in any proxy statement); (iv) in evaluating the independence of the independent accountants; (v) in complying with legal and regulatory requirements that relate to the Trust’s accounting and financial reporting, internal controls and independent audits; and (vi) to assume such other responsibilities as may be delegated by the Board. The Audit Committee met five times during the fiscal year ended July 31, 2011.

The Nominating and Governance Committee nominates individuals for Independent Trustee membership on the Board. The Nominating and Governance Committee functions include, but are not limited to, the following: (i) reviewing the qualifications of any person properly identified or nominated to serve as an Independent Trustee; (ii) recommending to the Board and current Independent Trustees the nominee(s) for appointment as an Independent Trustee by the Board and current Independent Trustees and/or for election as Independent Trustees by shareholders to fill any vacancy for a position of Independent Trustee(s) on the Board; (iii) recommending to the Board and current Independent Trustees the size and composition of the Board and Board committees and whether they comply with applicable laws and regulations; (iv) recommending a current Independent Trustee to the Board and current Independent Trustees to serve as Lead Independent Trustee; (v) periodic review of the Board’s retirement policy; and (vi) recommending an appropriate level of compensation for the Independent Trustees for their services as Trustees, members or chairpersons of committees of the Board, Lead Independent Trustee, Chairperson of the Board and any other positions as the Nominating and Governance Committee considers appropriate. The Nominating and Governance Committee does not consider Board nomination(s) recommended by shareholders (acting solely in their capacity as a shareholder and not in any other capacity). The Nominating and Governance Committee is comprised of all members of the Board that are Independent Trustees. The Nominating and Governance Committee met five times during the fiscal year ended July 31, 2011.

Potential Conflicts of Interest. Barclays PLC (“Barclays”) and The PNC Financial Services Group, Inc. (“PNC”), each has a significant economic interest in BlackRock, Inc., the parent of BFA, the Funds’ investment adviser. PNC is considered to be an affiliate of BlackRock, Inc., under the 1940 Act. Certain activities of BlackRock Advisors, LLC, BlackRock, Inc. and their affiliates (collectively, “BlackRock”) and PNC and its affiliates (collectively, “PNC” and together with BlackRock, “Affiliates”), and those of Barclays and its affiliates (collectively, the “Barclays Entities”), with respect to the Funds and/or other accounts managed by BlackRock, PNC or Barclays Entities, may give rise to actual or perceived conflicts of interest such as those described below.

BlackRock is one of the world’s largest asset management firms. PNC is a diversified financial services organization spanning the retail, business and corporate markets. Barclays is a major global financial services provider engaged in a range of activities, including retail and commercial banking, credit cards, investment banking, and wealth management. BlackRock and PNC are affiliates of one another under the 1940 Act. BlackRock, PNC, Barclays and their respective affiliates (including, for these purposes, their directors, partners, trustees, managing members, officers and employees), including the entities and personnel who may be involved in the investment activities and business operations of a Fund, are engaged worldwide in businesses, including equity, fixed income, cash management and alternative investments. These are considerations of which investors in a Fund should be aware, and which may cause conflicts of interest that could disadvantage the Fund and its shareholders. These activities and interests include potential multiple advisory, transactional, financial and other interests in securities and other instruments that may be purchased or sold by a Fund.

BlackRock and its Affiliates, as well as the Barclays Entities, have proprietary interests in, and may manage or advise with respect to, accounts or funds (including separate accounts and other funds and collective investment vehicles) that have investment objectives similar to those of a Fund and/or that engage in transactions in the same types of securities, currencies and instruments as the Fund. One or more Affiliates and Barclays Entities are also major participants in the global currency, equities, swap and fixed income markets, in each case both on a proprietary basis and for the accounts of customers. As such, one or more Affiliates or Barclays Entities are or may be actively engaged in transactions in the same securities, currencies, and instruments in which a Fund invests. Such activities could affect the prices and availability of the securities, currencies, and instruments in which a Fund invests, which could have an adverse impact on the Fund’s performance. Such transactions, particularly in respect of most proprietary accounts or customer accounts, will be executed independently of a Fund’s transactions and thus at prices or rates that may be more or less favorable than those obtained by the Fund. When BlackRock and its Affiliates purchase or sell the same assets for their managed accounts, including a Fund, the assets actually purchased or sold may be allocated among the accounts on a basis determined in their good faith discretion to be equitable. In some cases, this system may adversely affect the size or price of the assets purchased or sold for a Fund. In addition, transactions in investments by one or more other accounts managed by BlackRock or its Affiliates or a Barclays Entity may have the effect of diluting or otherwise disadvantaging the values, prices or investment strategies of a Fund, particularly, but not limited to, with respect to small capitalization, emerging market or less liquid strategies. This may occur when investment decisions regarding a Fund are based on research or other information that is also used to support decisions for other accounts. When BlackRock or its Affiliates or a Barclays Entity implements a portfolio decision or strategy on behalf of another account ahead of, or contemporaneously with, similar decisions or strategies for a Fund, market impact, liquidity constraints, or other factors could result in the Fund receiving less favorable trading results and the costs of implementing such decisions or strategies could be increased or the Fund could otherwise be disadvantaged. BlackRock or its Affiliates or a Barclays Entity may, in certain cases, elect to implement internal policies and procedures designed to limit such consequences, which may cause a Fund to be unable to engage in certain activities, including purchasing or disposing of securities, when it might otherwise be desirable for it to do so.

Conflicts may also arise because portfolio decisions regarding a Fund may benefit other accounts managed by BlackRock or its Affiliates or a Barclays Entity. For example, the sale of a long position or establishment of a short position by a Fund may impair the price of the same security sold short by (and therefore benefit) one or more Affiliates or Barclays Entities or their other accounts, and the purchase of a security or covering of a short position in a security by a Fund may increase the price of the same security held by (and therefore benefit) one or more Affiliates or Barclays Entities or their other accounts.

BlackRock and its Affiliates or a Barclays Entity and their clients may pursue or enforce rights with respect to an issuer in which a Fund has invested, and those activities may have an adverse effect on the Fund. As a result, prices, availability, liquidity and terms of a Fund’s investments may be negatively impacted by the activities of BlackRock or its Affiliates or a Barclays Entity or their clients, and transactions for the Fund may be impaired or effected at prices or terms that may be less favorable than would otherwise have been the case.

The results of a Fund’s investment activities may differ significantly from the results achieved by BlackRock and its Affiliates or the Barclays Entities for their proprietary accounts or other accounts (including investment companies or collective investment vehicles) managed or advised by them. It is possible that one or more Affiliate- or Barclays Entity-managed accounts and such other accounts will achieve investment results that are substantially more or less favorable than the results achieved by a Fund. Moreover, it is possible that a Fund will sustain losses during periods in which one or more Affiliates or Barclays Entity-managed accounts achieve significant profits on their trading for proprietary or other accounts. The opposite result is also possible. The investment activities of one or more Affiliates or Barclays Entities for their proprietary accounts and accounts under their management may also limit the investment opportunities for a Fund in certain emerging and other markets in which limitations are imposed upon the amount of investment, in the aggregate or in individual issuers, by affiliated foreign investors.

From time to time, a Fund’s activities may also be restricted because of regulatory restrictions applicable to one or more Affiliates or Barclays Entities, and/or their internal policies designed to comply with such restrictions. As a result, there may be periods, for example, when BlackRock, and/or one or more Affiliates or Barclays Entities, will not initiate or recommend certain types of transactions in certain securities or instruments with respect to which BlackRock and/or one or more Affiliates or Barclays Entities are performing services or when position limits have been reached.

In connection with its management of a Fund, BlackRock may have access to certain fundamental analysis and proprietary technical models developed by one or more Affiliates or Barclays Entities. BlackRock will not be under any obligation, however, to effect transactions on behalf of a Fund in accordance with such analysis and models. In addition, neither BlackRock nor any of its Affiliates, nor any Barclays Entity, will have any obligation to make available any information regarding their proprietary activities or strategies, or the activities or strategies used for other accounts managed by them, for the benefit of the management of a Fund and it is not anticipated that BlackRock will have access to such information for the purpose of managing the Fund. The proprietary activities or portfolio strategies of BlackRock and its Affiliates and the Barclays Entities, or the activities or strategies used for accounts managed by them or other customer accounts could conflict with the transactions and strategies employed by BlackRock in managing a Fund.

In addition, certain principals and certain employees of BlackRock are also principals or employees of Affiliates. As a result, the performance by these principals and employees of their obligations to such other entities may be a consideration of which investors in a Fund should be aware.

BlackRock may enter into transactions and invest in securities, instruments and currencies on behalf of a Fund in which customers of BlackRock or its Affiliates or a Barclays Entity, or, to the extent permitted by the SEC, BlackRock or another Affiliate or a Barclays Entity, serves as the counterparty, principal or issuer. In such cases, such party’s interests in the transaction will be adverse to the interests of the Fund, and such party may have no incentive to assure that the Fund obtains the best possible prices or terms in connection with the transactions. In addition, the purchase, holding and sale of such investments by a Fund may enhance the profitability of BlackRock or its Affiliates or a Barclays Entity. One or more Affiliates or Barclays Entities may also create, write or issue derivatives for their customers, the underlying securities, currencies or instruments of which may be those in which a Fund invests or which may be based on the performance of the Fund. A Fund may, subject to applicable law, purchase investments that are the subject of an underwriting or other distribution by one or more Affiliates or Barclays Entities and may also enter into transactions with other clients of an Affiliate or Barclays Entity where such other clients have interests adverse to those of the Fund.

At times, these activities may cause departments of BlackRock or its Affiliates or a Barclays Entity to give advice to clients that may cause these clients to take actions adverse to the interests of the Fund. To the extent affiliated transactions are permitted, a Fund will deal with BlackRock and its Affiliates or Barclays Entities on an arms-length basis. BlackRock or its Affiliates or a Barclays Entity may also have an ownership interest in certain trading or information systems used by a Fund. A Fund’s use of such trading or information systems may enhance the profitability of BlackRock and its Affiliates or Barclays Entities.

One or more Affiliates or one of the Barclays Entities may act as broker, dealer, agent, lender or adviser or in other commercial capacities for a Fund. It is anticipated that the commissions, mark-ups, mark-downs, financial advisory fees, underwriting and placement fees, sales fees, financing and commitment fees, brokerage fees, other fees, compensation or profits, rates, terms and conditions charged by an Affiliate or Barclays Entity will be in its view commercially reasonable, although each Affiliate or Barclays Entity, including its sales personnel, will have an interest in obtaining fees and other amounts that are favorable to the Affiliate or Barclays Entity and such sales personnel.

Subject to applicable law, the Affiliates and Barclays Entities (and their personnel and other distributors) will be entitled to retain fees and other amounts that they receive in connection with their service to the Funds as broker, dealer, agent, lender, adviser or in other commercial capacities and no accounting to the Funds or their shareholders will be required, and no fees or other compensation payable by the Funds or their shareholders will be reduced by reason of receipt by an Affiliate or Barclays Entity of any such fees or other amounts.

When an Affiliate or Barclays Entity acts as broker, dealer, agent, adviser or in other commercial capacities in relation to the Funds, the Affiliate or Barclays Entity may take commercial steps in its own interests, which may have an adverse effect on the Funds. A Fund will be required to establish business relationships with its counterparties based on the Fund’s own credit standing. Neither BlackRock nor any of the Affiliates, nor any Barclays Entity, will have any obligation to allow their credit to be used in connection with a Fund’s establishment of its business relationships, nor is it expected that the Fund’s counterparties will rely on the credit of BlackRock or any of the Affiliates or Barclays Entities in evaluating the Fund’s creditworthiness.

Purchases and sales of securities for a Fund may be bunched or aggregated with orders for other BlackRock client accounts. BlackRock, however, is not required to bunch or aggregate orders if portfolio management decisions for different accounts are made separately, or if it determines that bunching or aggregating is not practicable or required, or in cases involving client direction.

Prevailing trading activity frequently may make impossible the receipt of the same price or execution on the entire volume of securities purchased or sold. When this occurs, the various prices may be averaged, and the Funds will be charged or credited with the average price. Thus, the effect of the aggregation may operate on some occasions to the disadvantage of the Funds. In addition, under certain circumstances, the Funds will not be charged the same commission or commission equivalent rates in connection with a bunched or aggregated order.

BlackRock may select brokers (including, without limitation, Affiliates or Barclays Entities) that furnish BlackRock, the Funds, other BlackRock client accounts or other Affiliates or Barclays Entities or personnel, directly or through correspondent relationships, with research or other appropriate services which provide, in BlackRock’s view, appropriate assistance to BlackRock in the investment decision-making process (including with respect to futures, fixed-price offerings and over-the-counter transactions). Such research or other services may include, to the extent permitted by law, research reports on companies, industries and securities; economic and financial data; financial publications; proxy analysis; trade industry seminars; computer data bases; research-oriented software and other services and products. Research or other services obtained in this manner may be used in servicing any or all of the Funds and other BlackRock client accounts, including in connection with BlackRock client accounts other than those that pay commissions to the broker relating to the research or other service arrangements. Such products and services may disproportionately benefit other BlackRock client accounts relative to the Funds based on the amount of brokerage commissions paid by the Funds and such other BlackRock client accounts. For example, research or other services that are paid for through one client’s commissions may not be used in managing that client’s account. In addition, other BlackRock client accounts may receive the benefit, including disproportionate benefits, of economies of scale or price discounts in connection with products and services that may be provided to the Funds and to such other BlackRock client accounts. To the extent that BlackRock uses soft dollars, it will not have to pay for those products and services itself.

BlackRock may receive research that is bundled with the trade execution, clearing, and/or settlement services provided by a particular broker-dealer. To the extent that BlackRock receives research on this basis, many of the same conflicts related to traditional soft dollars may exist. For example, the research effectively will be paid by client commissions that also will be used to pay for the execution, clearing, and settlement services provided by the broker-dealer and will not be paid by BlackRock.

BlackRock may endeavor to execute trades through brokers who, pursuant to such arrangements, provide research or other services in order to ensure the continued receipt of research or other services BlackRock believes are useful in its investment decision-making process. BlackRock may from time to time choose not to engage in the above described arrangements to varying degrees. BlackRock may also enter into commission sharing arrangements under which BlackRock may execute transactions through a broker-dealer, including, where permitted, an Affiliate or Barclays Entity, and request that the broker-dealer allocate a portion of the commissions or commission credits to another firm that provides research to BlackRock. To the extent that BlackRock engages in commission sharing arrangements, many of the same conflicts related to traditional soft dollars may exist.

BlackRock may utilize certain electronic crossing networks (“ECNs”) in executing client securities transactions for certain types of securities. These ECNs may charge fees for their services, including access fees and transaction fees. The transaction fees, which are similar to commissions or markups/markdowns, will generally be charged to clients and, like commissions and markups/markdowns, would generally be included in the cost of the securities purchased. Access fees may be paid by BlackRock even though incurred in connection with executing transactions on behalf of clients, including the Funds. In certain circumstances, ECNs may offer volume discounts that will reduce the access fees typically paid by BlackRock. This would have the effect of reducing the access fees paid by BlackRock. BlackRock will only utilize ECNs consistent with its obligation to seek to obtain best execution in client transactions.

BlackRock has adopted policies and procedures designed to prevent conflicts of interest from influencing proxy voting decisions that it makes on behalf of advisory clients, including the Funds, and to help ensure that such decisions are made in accordance with BlackRock’s fiduciary obligations to its clients. Nevertheless, notwithstanding such proxy voting policies and procedures, actual proxy voting decisions of BlackRock may have the effect of favoring the interests of other clients or businesses of other divisions or units of BlackRock and/or its Affiliates or a Barclays Entity, provided that BlackRock believes such voting decisions to be in accordance with its fiduciary obligations. For a more detailed discussion of these policies and procedures, see the Proxy Voting Policy section of this SAI.

It is also possible that, from time to time, BlackRock or its Affiliates or a Barclays Entity may, although they are not required to, purchase and hold shares of a Fund. Increasing a Fund’s assets may enhance investment flexibility and diversification and may contribute to economies of scale that tend to reduce the Fund’s expense ratio. BlackRock and its Affiliates or Barclays Entities reserve the right to redeem at any time some or all of the shares of a Fund acquired for their own accounts. A large redemption of shares of a Fund by BlackRock or its Affiliates or by a Barclays Entity could significantly reduce the asset size of the Fund, which might have an adverse effect on the Fund’s investment flexibility, portfolio diversification and expense ratio. BlackRock will consider the effect of redemptions on a Fund and other shareholders in deciding whether to redeem its shares.

It is possible that a Fund may invest in securities of companies with which an Affiliate or a Barclays Entity has or is trying to develop investment banking relationships as well as securities of entities in which BlackRock or its Affiliates or a Barclays Entity has significant debt or equity investments or in which an Affiliate or Barclays Entity makes a market. A Fund also may invest in securities of companies to which an Affiliate or a Barclays Entity provides or may some day provide research coverage. Such investments could cause conflicts between the interests of a Fund and the interests of other clients of BlackRock or its Affiliates or a Barclays Entity. In making investment decisions for a Fund, BlackRock is not permitted to obtain or use material non-public information acquired by any division, department or Affiliate of BlackRock or of a Barclays Entity in the course of these activities. In addition, from time to time, the activities of an Affiliate or a Barclays Entity may limit a Fund’s flexibility in purchases and sales of securities. When an Affiliate is engaged in an underwriting or other distribution of securities of an entity, BlackRock may be prohibited from purchasing or recommending the purchase of certain securities of that entity for a Fund.

BlackRock and its Affiliates and the Barclays Entities, their personnel and other financial service providers may have interests in promoting sales of the Funds. With respect to BlackRock and its Affiliates and Barclays Entities and their personnel, the remuneration and profitability relating to services to and sales of the Funds or other products may be greater than remuneration and profitability relating to services to and sales of certain funds or other products that might be provided or offered. BlackRock and its Affiliates or Barclays Entities and their sales personnel may directly or indirectly receive a portion of the fees and commissions charged to the Funds or their shareholders. BlackRock and its advisory or other personnel may also benefit from increased amounts of assets under management. Fees and commissions may also be higher than for other products or services, and the remuneration and profitability to BlackRock or its Affiliates or a Barclays Entity and such personnel resulting from transactions on behalf of or management of the Funds may be greater than the remuneration and profitability resulting from other funds or products.

BlackRock and its Affiliates or a Barclays Entity and their personnel may receive greater compensation or greater profit in connection with an account for which BlackRock serves as an adviser than with an account advised by an unaffiliated investment adviser. Differentials in compensation may be related to the fact that BlackRock may pay a portion of its advisory fee to its Affiliate or to a Barclays Entity, or relate to compensation arrangements, including for portfolio management, brokerage transactions or account servicing. Any differential in compensation may create a financial incentive on the part of BlackRock or its Affiliates or Barclays Entities and their personnel to recommend BlackRock over unaffiliated investment advisers or to effect transactions differently in one account over another.

BlackRock and its Affiliates or a Barclays Entity may provide valuation assistance to certain clients with respect to certain securities or other investments and the valuation recommendations made for their clients’ accounts may differ from the valuations for the same securities or investments assigned by a Fund’s pricing vendors, especially if such valuations are based on broker-dealer quotes or other data sources unavailable to the Fund’s pricing vendors. While BlackRock will generally communicate its valuation information or determinations to a Fund’s pricing vendors and/or fund accountants, there may be instances where the Fund’s pricing vendors or fund accountants assign a different valuation to a security or other investment than the valuation for such security or investment determined or recommended by BlackRock.

As disclosed in more detail in the Determination of Net Asset Value section of each Fund’s Prospectus, when market valuations are not readily available or such valuations do not reflect current market values, the affected investments will be valued using fair value pricing, pursuant to procedures adopted by the Fund’s Board. As a result, the Funds’ sale or redemption of its shares at net asset value, at a time when a holding or holdings are valued by BlackRock (pursuant to Board-adopted procedures) at fair value, may have the effect of diluting or increasing the economic interest of existing shareholders.

To the extent permitted by applicable law, a Fund may invest all or some of its short term cash investments in any money market fund or similarly-managed private fund advised or managed by BlackRock. In connection with any such investments, a Fund, to the extent permitted by the 1940 Act, may pay its share of expenses of a money market fund in which it invests, which may result in a Fund bearing some additional expenses.

BlackRock and its Affiliates or a Barclays Entity and their directors, officers and employees, may buy and sell securities or other investments for their own accounts, and may have conflicts of interest with respect to investments made on behalf of a Fund. As a result of differing trading and investment strategies or constraints, positions may be taken by directors, officers, employees and Affiliates of BlackRock or by Barclays Entities that are the same, different from or made at different times than positions taken for the Fund. To lessen the possibility that a Fund will be adversely affected by this personal trading, the Fund, BFA and BlackRock each has adopted a Code of Ethics in compliance with Section 17(j) of the 1940 Act that restricts securities trading in the personal accounts of investment professionals and others who normally come into possession of information regarding the Fund’s portfolio transactions. Each Code of Ethics can be reviewed and copied at the SEC’s Public Reference Room in Washington, D.C. Information on the operation of the Public Reference Room may be obtained by calling the SEC at (202) 551-8090. Each Code of Ethics is also available on the EDGAR Database on the SEC’s Internet site at http://www.sec.gov, and copies may be obtained, after paying a duplicating fee, by e-mail at publicinfo@sec.gov or by writing the SEC’s Public Reference Section, Washington, DC 20549-1520.

BlackRock and its Affiliates will not purchase securities or other property from, or sell securities or other property to, a Fund, except that the Fund may in accordance with rules adopted under the 1940 Act engage in transactions with accounts that are affiliated with the Fund as a result of common officers, directors, or investment advisers or pursuant to exemptive orders granted to the Funds and/or BlackRock by the SEC. These transactions would be affected in circumstances in which BlackRock determined that it would be appropriate for the Fund to purchase and another client of BlackRock to sell, or the Fund to sell and another client of BlackRock to purchase, the same security or instrument on the same day. From time to time, the activities of a Fund may be restricted because of regulatory requirements applicable to BlackRock or its Affiliates or a Barclays Entity and/or BlackRock’s internal policies designed to comply with, limit the applicability of, or otherwise relate to such requirements. A client not advised by BlackRock would not be subject to some of those considerations. There may be periods when BlackRock may not initiate or recommend certain types of transactions, or may otherwise restrict or limit their advice in certain securities or instruments issued by or related to companies for which an Affiliate or a Barclays Entity is performing investment banking, market making or other services or has proprietary positions. For example, when an Affiliate is engaged in an underwriting or other distribution of securities of, or advisory services for, a company, the Funds may be prohibited from or limited in purchasing or selling securities of that company. Similar situations could arise if personnel of BlackRock or its Affiliates or a Barclays Entity serve as directors of companies the securities of which the Funds wish to purchase or sell. However, if permitted by applicable law, the Funds may purchase securities or instruments that are issued by such companies or are the subject of an underwriting, distribution, or advisory assignment by an Affiliate or a Barclays Entity, or in cases in which personnel of BlackRock or its Affiliates or of Barclays Entities are directors or officers of the issuer.

The investment activities of one or more Affiliates or Barclays Entities for their proprietary accounts and for client accounts may also limit the investment strategies and rights of the Funds. For example, in regulated industries, in certain emerging or international markets, in corporate and regulatory ownership definitions, and in certain futures and derivative transactions, there may be limits on the aggregate amount of investment by affiliated investors that may not be exceeded without the

grant of a license or other regulatory or corporate consent or, if exceeded, may cause BlackRock, the Funds or other client accounts to suffer disadvantages or business restrictions.

If certain aggregate ownership thresholds are reached or certain transactions undertaken, the ability of BlackRock on behalf of clients (including the Funds) to purchase or dispose of investments, or exercise rights or undertake business transactions, may be restricted by regulation or otherwise impaired. As a result, BlackRock, on behalf of clients (including the Funds), may limit purchases, sell existing investments, or otherwise restrict or limit the exercise of rights (including voting rights) when BlackRock, in its sole discretion, deems it appropriate.

BlackRock and its Affiliates and Barclays Entities may maintain securities indices as part of their product offerings. Index based funds seek to track the performance of securities indices and may use the name of the index in the fund name. Index providers, including BlackRock and its Affiliates and Barclays Entities may be paid licensing fees for use of their index or index name. BlackRock and its Affiliates and Barclays Entities will not be obligated to license their indices to BlackRock, and BlackRock cannot be assured that the terms of any index licensing agreement with BlackRock and its Affiliates and Barclays Entities will be as favorable as those terms offered to other index licensees.

BlackRock and its Affiliates and Barclays Entities may serve as Authorized Participants in the creation and redemption of exchange-traded funds, including funds advised by Affiliates of BlackRock. As described in greater detail in the Creations and Redemptions section of the prospectus, BlackRock and its Affiliates and Barclays Entities may therefore be deemed to be participants in a distribution of iShares funds that could render them statutory underwriters.

Present and future activities of BlackRock and its Affiliates and Barclays Entities, including BlackRock Advisors, LLC, in addition to those described in this section, may give rise to additional conflicts of interest.

Investment Advisory, Administrative and Distribution Services

Investment Adviser. BFA serves as investment adviser to each Fund pursuant to an Investment Advisory Agreement between the Trust, on behalf of each Fund, and BFA. BFA is a California corporation indirectly owned by BlackRock, Inc. and is registered as an investment adviser under the Investment Advisers Act of 1940, as amended. Under the Investment Advisory Agreement, BFA, subject to the supervision of the Board and in conformity with the stated investment policies of each Fund, manages and administers the Trust and the investment of each Fund’s assets. BFA is responsible for placing purchase and sale orders and providing continuous supervision of the investment portfolio of each Fund.

Pursuant to the Investment Advisory Agreement, BFA may, from time to time, in its sole discretion and to the extent permitted by applicable law, appoint one or more sub-advisers, including, without limitation, affiliates of BFA, to perform investment advisory or other services with respect to a Fund. In addition, BFA may delegate certain of its investment advisory functions under the Investment Advisory Agreement to one or more of its affiliates to the extent permitted by applicable law.

Pursuant to the Investment Advisory Agreement, BFA is responsible for substantially all expenses of the Funds, including the cost of transfer agency, custody, fund administration, legal, audit and other services. BFA is not responsible for, and the Funds will bear the cost of, interest expense, taxes, brokerage expenses and other expenses connected with the execution of portfolio securities transactions, distribution fees and extraordinary expenses.

1 For the iShares MSCI Emerging Markets Financials Sector Index Fund, BFA may voluntarily waive a portion of the management fee, as it determines, from time to time. During the period from September 1, 2010 through December 31, 2010, BFA voluntarily waived a portion of its management fee. For the fiscal year ended July 31, 2011, BFA waived $274 of its management fees.
2 For the iShares MSCI Emerging Markets Materials Sector Index Fund, BFA may voluntarily waive a portion of the management fee, as it determines, from time to time. During the period from September 1, 2010 through December 31, 2010, BFA voluntarily waived a portion of its management fee. For the fiscal year ended July 31, 2011, BFA waived $196 of its management fees.

The Investment Advisory Agreement with respect to each Fund continues in effect for two years from its effective date, and thereafter is subject to annual approval by (i) the Board, or (ii) the vote of a majority of the outstanding voting securities (as defined in the 1940 Act) of the applicable Fund, provided that in either event such continuance also is approved by a majority of the Board who are not interested persons (as defined in the 1940 Act) of the applicable Fund, by a vote cast in person at a meeting called for the purpose of voting on such approval.

The Investment Advisory Agreement with respect to each Fund is terminable without penalty, on 60 days’ notice, by the Board or by a vote of the holders of a majority of the applicable Fund’s outstanding voting securities (as defined in the 1940 Act). The Investment Advisory Agreement is also terminable upon 60 days’ notice by BFA and will terminate automatically in the event of its assignment (as defined in the 1940 Act).

Current interpretations of U.S. federal banking laws and regulations (i) may prohibit BlackRock, Inc., BTC and BFA from controlling or underwriting the shares of the Funds, but (ii) do not prohibit BlackRock, Inc. or BFA generally from acting as an investment adviser, administrator, transfer agent or custodian to the Funds or from purchasing shares as agent for and upon the order of a customer.

BFA believes that it may perform advisory and related services for the Trust without violating applicable banking laws or regulations. However, the legal requirements and interpretations about the permissible activities of banks and their affiliates may change in the future. These changes could prevent BFA from continuing to perform services for the Trust. If this happens, the Board would consider selecting other qualified firms. Any new investment advisory agreement would be subject to shareholder approval.

If current restrictions on bank activities with mutual funds were relaxed, BFA, or its affiliates, would consider performing additional services for the Trust. BFA cannot predict whether these changes will be enacted, or the terms under which BFA, or its affiliates, might offer to provide additional services.

Portfolio Managers. As of July 31, 2011, the individuals named as Portfolio Managers in the Funds’ Prospectuses were also primarily responsible for the day-to-day management of other iShares funds and certain other types of portfolios and/or accounts as indicated in the tables below:

Each of the portfolios or accounts for which the Portfolio Managers are primarily responsible for the day-to-day management seeks to track the rate of return, risk profile and other characteristics of independent third-party indexes by either replicating the same combination of securities that constitute those indexes or through a representative sampling of the securities that constitute those indexes based on objective criteria and data. Pursuant to BTC and BFA policy, investment opportunities are allocated equitably among the Funds and other portfolios and accounts. For example, under certain circumstances, an investment opportunity may be restricted due to limited supply on the market, legal constraints or other factors, in which event the investment opportunity will be allocated equitably among those portfolios and accounts, including the Funds seeking such investment opportunity. As a consequence, from time to time the Funds may receive a smaller allocation of an investment opportunity than they would have if the Portfolio Managers and BFA and its affiliates did not manage other portfolios or accounts.

Like the Funds, the other portfolios or accounts for which the Portfolio Managers are primarily responsible for the day-to-day portfolio management generally pay an asset-based fee to BFA or BTC, as applicable, for its advisory services. One or more of those other portfolios or accounts, however, may pay BTC an incentive-based fee in lieu of, or in addition to, an asset-based fee for its advisory services. A portfolio or account with an incentive-based fee would pay BTC a portion of that portfolio’s or account’s gains, or would pay BTC more for its services than would otherwise be the case if BTC meets or exceeds specified performance targets. By their nature, incentive-based fee arrangements could present an incentive for BTC to devote greater resources, and allocate more investment opportunities, to the portfolios or accounts that have those fee arrangements, relative to other portfolios or accounts, in order to earn larger fees. Although BTC has an obligation to allocate resources and opportunities equitably among portfolios and accounts and intends to do so, shareholders of the Funds should be aware that, as with any group of portfolios and accounts managed by an investment adviser and/or its affiliates pursuant to varying fee arrangements, including incentive-based fee arrangements, there is the potential for a conflict of interest that may result in the Portfolio Managers’ favoring those portfolios or accounts with incentive-based fee arrangements.

The tables below show, for each Portfolio Manager, the number of portfolios or accounts of the types set forth in the above tables and the aggregate of total assets in those portfolios or accounts with respect to which the investment management fees are based on the performance of those portfolios or accounts as of July 31, 2011:

The discussion below describes the Portfolio Managers’ compensation as of July 31, 2011.

Portfolio Manager Compensation Overview

Base compensation. Generally, portfolio managers receive base compensation based on their seniority and/or their position with the firm. Senior portfolio managers who perform additional management functions within the portfolio management group or within BlackRock may receive additional compensation for serving in these other capacities.

Discretionary Incentive Compensation. Discretionary incentive compensation is a function of several components: the performance of BlackRock, Inc., the performance of the portfolio manager’s group within BlackRock, the investment performance, including risk-adjusted returns, of the firm’s assets under management or supervision by that portfolio manager relative to predetermined benchmarks, and the individual’s seniority, role within the portfolio management team, teamwork and contribution to the overall performance of these portfolios and BlackRock.

Distribution of Discretionary Incentive Compensation. Discretionary incentive compensation is distributed to portfolio managers in a combination of cash and BlackRock, Inc. restricted stock units which vest ratably over a number of years. The BlackRock, Inc. restricted stock units, if properly vested, will be settled in BlackRock, Inc. common stock. Typically, the cash bonus, when combined with base salary, represents more than 60% of total compensation for the portfolio managers. Paying a portion of annual bonuses in stock puts compensation earned by a portfolio manager for a given year “at risk” based on BlackRock’s ability to sustain and improve its performance over future periods.

From time to time, long-term incentive equity awards are granted to certain key employees to aid in retention, align their interests with long-term shareholder interests and motivate performance. Equity awards are generally granted in the form of BlackRock, Inc. restricted stock units that, once vested, settle in BlackRock, Inc. common stock.

As of July 31, 2011, the Portfolio Managers beneficially owned shares of the Funds, for which they are primarily responsible for the day-to-day management, in the amounts reflected in the following tables:

Codes of Ethics. The Trust, BFA and the Distributor have adopted Codes of Ethics pursuant to Rule 17j-1 of the 1940 Act. The Codes of Ethics permit personnel subject to the Codes of Ethics to invest in securities, subject to certain limitations, including securities that may be purchased or held by the Funds. The Codes of Ethics are on public file with, and are available from, the SEC.

Anti-Money Laundering Requirements. The Funds are subject to the USA PATRIOT Act (the “Patriot Act”). The Patriot Act is intended to prevent the use of the U.S. financial system in furtherance of money laundering, terrorism or other illicit activities. Pursuant to requirements under the Patriot Act, a Fund may request information from Authorized Participants to enable it to form a reasonable belief that it knows the true identity of its Authorized Participants. This information will be used to verify the identity of Authorized Participants or, in some cases, the status of financial professionals; it will be used only for compliance with the requirements of the Patriot Act.

The Funds reserve the right to reject purchase orders from persons who have not submitted information sufficient to allow the Fund to verify their identity. Each Fund also reserves the right to redeem any amounts in a Fund from persons whose identity it is unable to verify on a timely basis. It is the Funds’ policy to cooperate fully with appropriate regulators in any investigations conducted with respect to potential money laundering, terrorism or other illicit activities.

Administrator, Custodian and Transfer Agent. State Street Bank and Trust Company (“State Street”) serves as administrator, custodian and transfer agent for the Funds under the Master Services Agreement and related Service Schedule (the “Service Module”). State Street’s principal address is 200 Clarendon Street, Boston, MA 02116. Pursuant to the Service Module for Fund Administration and Accounting Services with the Trust, State Street provides necessary administrative, legal, tax and accounting and financial reporting services for the maintenance and operations of the Trust and each Fund. In addition, State Street makes available the office space, equipment, personnel and facilities required to provide such services. Pursuant to the Service Module for Custodial Services with the Trust, State Street maintains, in separate accounts, cash, securities and other assets of the Trust and each Fund, keeps all necessary accounts and records and provides other services. State Street is required, upon the order of the Trust, to deliver securities held by State Street and to make payments for securities purchased by the Trust for each Fund. State Street is authorized to appoint certain foreign custodians or foreign custody managers for Fund investments outside the United States. Pursuant to the Service Module for Transfer Agency

Services with the Trust, State Street acts as a transfer agent for each Fund’s authorized and issued shares of beneficial interest, and as dividend disbursing agent of the Trust. As compensation for these services, State Street receives certain out-of-pocket costs, transaction fees and asset-based fees which are accrued daily and paid monthly by BFA from its management fee.

Distributor. The Distributor’s principal address is One Freedom Valley Drive, Oaks, PA 19456. The Distributor has entered into a Distribution Agreement with the Trust pursuant to which it distributes shares of each Fund. The Distribution Agreement will continue for two years from its effective date and is renewable annually. Shares are continuously offered for sale by the Funds through the Distributor only in Creation Units, as described in the applicable Prospectus and below in the Creation and Redemption of Creation Units section of this SAI. Fund shares in amounts less than Creation Units are not distributed by the Distributor. The Distributor will deliver the applicable Prospectus and, upon request, the SAI to persons purchasing Creation Units and will maintain records of both orders placed with it and confirmations of acceptance furnished by it. The Distributor is a broker-dealer registered under the Securities Exchange Act of 1934, as amended (the “1934 Act”), and a member of the Financial Industry Regulatory Authority, Inc. (“FINRA”).

The Distribution Agreement for each Fund provides that it may be terminated at any time, without the payment of any penalty, on at least 60 days’ prior written notice to the other party following (i) the vote of a majority of the Independent Trustees, or (ii) the vote of a majority of the outstanding voting securities (as defined in the 1940 Act) of the relevant Fund. The Distribution Agreement will terminate automatically in the event of its assignment (as defined in the 1940 Act).

The Distributor may also enter into agreements with securities dealers (“Soliciting Dealers”) who will solicit purchases of Creation Units of Fund shares. Such Soliciting Dealers may also be Authorized Participants (as defined below), DTC participants and/or investor services organizations.

BFA or BTC may, from time to time and from its own resources, pay, defray or absorb costs relating to distribution, including payments out of its own resources to the Distributor, or to otherwise promote the sale of shares.

The following table sets forth the compensation paid by BFA to the Distributor for certain services, not primarily intended to result in the sale of Fund shares, provided to each Fund during the fiscal years noted:

Financial Intermediary Compensation. BFA and/or BTC and/or their respective subsidiaries (“BFA Entities”) pay certain broker-dealers, banks and other financial intermediaries (“Intermediaries”) for certain activities related to the Funds, other iShares funds or exchange-traded products in general (“Payments”). BFA Entities make Payments from their own assets and not from the assets of the Funds. Although a portion of BFA Entities’ revenue comes directly or indirectly in part from fees paid by the Funds and other iShares funds, Payments do not increase the price paid by investors for the purchase of shares of, or the cost of owning, the Fund or other iShares funds. BFA Entities make Payments for Intermediaries’ participating in activities that are designed to make registered representatives, other professionals and individual investors more knowledgeable about exchange-traded products, including the Funds or for other activities, such as participation in

marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems (“Education Costs”). BFA Entities also make Payments to Intermediaries for certain printing, publishing and mailing costs associated with the Funds or materials relating to exchange-traded products in general (“Publishing Costs”). In addition, BFA Entities make Payments to Intermediaries that make shares of the Funds and certain other iShares funds available to their clients, develop new products that feature iShares or otherwise promote the Funds and other iShares funds. Payments of this type are sometimes referred to as revenue-sharing payments.

Payments to an Intermediary may be significant to the Intermediary, and amounts that Intermediaries pay to your salesperson or other investment professional may also be significant for your salesperson or other investment professional. Because an Intermediary may make decisions about which investment options it will recommend or make available to its clients or what services to provide for various products based on payments it receives or is eligible to receive, Payments create conflicts of interest between the Intermediary and its clients and these financial incentives may cause the Intermediary to recommend the Fund and other iShares funds over other investments. The same conflict of interest exists with respect to your salesperson or other investment professional if he or she receives similar payments from his or her Intermediary firm.

As of February 2, 2010, BFA Entities had arrangements to make Payments other than Education Costs or Publishing Costs only to Fidelity Brokerage Services LLC (“FBS”) and Merrill Lynch, Pierce, Fenner & Smith, Inc. (“ML”). Pursuant to BFA Entities’ arrangement with FBS, FBS has agreed to promote iShares funds to FBS’s customers and not to charge certain of its customers any commissions when those customers purchase or sell shares of certain iShares funds online (the “Co-Branded Marketing Program”). BFA Entities have agreed to facilitate the Co-Branded Marketing Program by making payments to FBS during the term of the agreement in a fixed amount. Upon termination of the agreement the BFA Entities will make additional payments to FBS based upon a number of criteria, including the overall success of the Co-Branded Marketing program and the level of services provided by FBS during the wind-down period. Pursuant to BFA Entities’ arrangement with ML, BFA Entities have agreed to reimburse ML for a portion of certain fee waivers that ML may be required to implement with respect to accounts that hold “plan assets” within the meaning of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”), as a consequence of a technical ERISA affiliate relationship between BFA and ML.

Any additions, modifications, or deletions to Intermediaries listed above that have occurred since the date noted above are not included in the list. Further, BFA Entities make Education Costs and Publishing Costs Payments to other Intermediaries that are not listed above. BFA Entities may determine to make Payments based on any number of metrics. For example, BFA Entities may make Payments at year-end or other intervals in a fixed amount, an amount based upon an Intermediary’s services at defined levels or an amount based on the Intermediary’s net sales of one or more iShares funds in a year or other period, any of which arrangements may include an agreed-upon minimum or maximum payment, or any combination of the foregoing. As of the date of this SAI, BFA anticipates that the Payments paid by BFA Entities in connection with the Funds, iShares funds and exchange-traded products in general will be immaterial to BFA Entities in the aggregate for the next year. Please contact your salesperson or other investment professional for more information regarding any Payments his or her Intermediary firm may receive. Any Payments made by the BFA Entities to an Intermediary may create the incentive for an Intermediary to encourage customers to buy shares of iShares funds.

Brokerage Transactions

BFA assumes general supervision over placing orders on behalf of each Fund for the purchase and sale of portfolio securities. In selecting brokers or dealers for any transaction in portfolio securities, BFA’s policy is to make such selection based on factors deemed relevant, including but not limited to, the breadth of the market in the security, the price of the security, the reasonableness of the commission or mark-up or mark-down, if any, execution capability, settlement capability, back office efficiency and the financial condition of the broker or dealer, both for the specific transaction and on a continuing basis. The overall reasonableness of brokerage commissions paid is evaluated by BFA based upon its knowledge of available information as to the general level of commissions paid by other institutional investors for comparable services. Brokers may also be selected because of their ability to handle special or difficult executions, such as may be involved in large block trades, less liquid securities, broad distributions, or other circumstances. BFA does not consider the provision or value of research, products or services a broker or dealer may provide, if any, as a factor in the selection of a broker or dealer or the determination of the reasonableness of commissions paid in connection with portfolio transactions. The Trust has adopted policies and procedures that prohibit the consideration of sales of a Fund’s shares as a factor in the selection of a broker or a dealer to execute its portfolio transactions.

The table below sets forth the brokerage commissions paid by each Fund for the fiscal years noted. Any differences in brokerage commissions paid by a Fund from year to year are due to increases or decreases in that Fund’s assets over those periods:

None of the Funds paid any brokerage commissions to BlackRock, an affiliate of BFA, and a subsidiary of BTC, during the fiscal year ended July 31, 2011.

The Funds’ purchase and sale orders for securities may be combined with those of other investment companies, clients or accounts that BFA or its Affiliates manage or advise and for which they have brokerage placement authority. If purchases or sales of portfolio securities of the Funds and one or more other accounts managed or advised by BFA or its Affiliates are considered at or about the same time, transactions in such securities are allocated among the Funds and the other accounts in a manner deemed equitable to all by BFA and its Affiliates. In some cases, this procedure could have a detrimental effect on the price or volume of the security as far as the Funds are concerned. However, in other cases, it is possible that the ability to participate in volume transactions and to negotiate lower transaction costs will be beneficial to the Funds. BFA and its Affiliates may deal, trade and invest for their own account in the types of securities in which the Funds may invest. BFA and its Affiliates may, from time to time, effect trades on behalf of and for the account of the Funds with brokers or dealers that are affiliated with BFA, in conformity with the 1940 Act and SEC rules and regulations. Under these provisions, any commissions paid to affiliated brokers or dealers must be reasonable and fair compared to the commissions charged by other brokers or dealers in comparable transactions. The Funds will not deal with affiliates in principal transactions unless permitted by applicable SEC rules or regulations, or by SEC exemptive order.

Portfolio turnover may vary from year to year, as well as within a year. High turnover rates may result in comparatively greater brokerage expenses. The table below sets forth the portfolio turnover rates of each Fund for the fiscal years noted:

Additional Information Concerning the Trust

Shares. The Trust currently consists of more than 190 separate investment series or portfolios called funds. The Trust issues shares of beneficial interests in each fund with no par value. The Board may designate additional iShares funds.

Each share issued by a fund has a pro rata interest in the assets of that fund. Shares have no preemptive, exchange, subscription or conversion rights and are freely transferable. Each share is entitled to participate equally in dividends and distributions declared by the Board with respect to the relevant fund, and in the net distributable assets of such fund on liquidation.

Each share has one vote with respect to matters upon which the shareholder is entitled to vote. In any matter submitted to shareholders for a vote, each fund shall hold a separate vote, provided that shareholders of all affected funds will vote together when: (1) required by the 1940 Act, or (2) the Trustees determine that the matter affects the interests of more than one fund.

Under Delaware law, the Trust is not required to hold an annual meeting of shareholders unless required to do so under the 1940 Act. The policy of the Trust is not to hold an annual meeting of shareholders unless required to do so under the 1940 Act. All shares (regardless of the fund) have noncumulative voting rights in the election of members of the Board. Under Delaware law, Trustees of the Trust may be removed by vote of the shareholders.

Following the creation of the initial Creation Unit(s) of shares of a fund and immediately prior to the commencement of trading in such fund’s shares, a holder of shares may be a “control person” of the fund, as defined in the 1940 Act. A fund cannot predict the length of time for which one or more shareholders may remain a control person of the fund.

In accordance with the Trust’s Amended and Restated Agreement and Declaration of Trust dated September 17, 2009 (the “Declaration of Trust”), the Board may, without shareholder approval (unless such shareholder approval is required by applicable law, including the 1940 Act), cause one or more funds commencing operations after September 24, 2008 (each, a “New Fund”) to merge, reorganize, consolidate, sell all or substantially all of their assets, or take other similar actions with, to or into another New Fund.

Shareholders may make inquiries by writing to iShares Trust, c/o SEI Investments Distribution Co., One Freedom Valley Drive, Oaks, PA 19456.

Absent an applicable exemption or other relief from the SEC or its staff, beneficial owners of more than 5% of the shares of a fund may be subject to the reporting provisions of Section 13 of the 1934 Act and the SEC’s rules promulgated thereunder. In addition, absent an applicable exemption or other relief from the SEC or its staff, officers and trustees of a fund and beneficial owners of 10% of the shares of a fund (“Insiders”) may be subject to the insider reporting, short-swing profit and short sale provisions of Section 16 of the 1934 Act and the SEC’s rules promulgated thereunder. Beneficial owners and Insiders should consult with their own legal counsel concerning their obligations under Sections 13 and 16 of the 1934 Act.

Termination of the Trust or a Fund. The Trust or a Fund may be terminated by a majority vote of the Board, subject to the affirmative vote of a majority of the shareholders of the Trust or such Fund entitled to vote on termination; however, in certain circumstances described in the Declaration of Trust, only a majority vote of the Board is required. Although the shares

are not automatically redeemable upon the occurrence of any specific event, the Declaration of Trust provides that the Board will have the unrestricted power to alter the number of shares in a Creation Unit. In the event of a termination of the Trust or a Fund, the Board, in its sole discretion, could determine to permit the shares to be redeemable in aggregations smaller than Creation Units or to be individually redeemable. In such circumstance, the Trust may make redemptions in-kind, for cash or for a combination of cash or securities.

DTC as Securities Depository for Shares of the Funds. Shares of each Fund are represented by securities registered in the name of DTC or its nominee and deposited with, or on behalf of, DTC.

DTC, a limited-purpose trust company, was created to hold securities of its participants (“DTC Participants”) and to facilitate the clearance and settlement of securities transactions among the DTC Participants in such securities through electronic book-entry changes in accounts of the DTC Participants, thereby eliminating the need for physical movement of securities’ certificates. DTC Participants include securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations, some of whom (and/or their representatives) own DTC. More specifically, DTC is owned by a number of its DTC Participants and by the NYSE, the NYSE Amex Equities and FINRA. Access to the DTC system is also available to others such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a DTC Participant, either directly or indirectly (“Indirect Participants”).

Beneficial ownership of shares is limited to DTC Participants, Indirect Participants and persons holding interests through DTC Participants and Indirect Participants. Ownership of beneficial interests in shares (owners of such beneficial interests are referred to herein as “Beneficial Owners”) is shown on, and the transfer of ownership is effected only through, records maintained by DTC (with respect to DTC Participants) and on the records of DTC Participants (with respect to Indirect Participants and Beneficial Owners that are not DTC Participants). Beneficial Owners will receive from or through the DTC Participant a written confirmation relating to their purchase of shares.

Conveyance of all notices, statements and other communications to Beneficial Owners is effected as follows. Pursuant to the Depositary Agreement between the Trust and DTC, DTC is required to make available to the Trust upon request and for a fee to be charged to the Trust a listing of the shares of each Fund held by each DTC Participant. The Trust shall inquire of each such DTC Participant as to the number of Beneficial Owners holding shares, directly or indirectly, through such DTC Participant. The Trust shall provide each such DTC Participant with copies of such notice, statement or other communication, in such form, number and at such place as such DTC Participant may reasonably request, in order that such notice, statement or communication may be transmitted by such DTC Participant, directly or indirectly, to such Beneficial Owners. In addition, the Trust shall pay to each such DTC Participant a fair and reasonable amount as reimbursement for the expenses attendant to such transmittal, all subject to applicable statutory and regulatory requirements.

Share distributions shall be made to DTC or its nominee, Cede & Co., as the registered holder of all shares of the Trust. DTC or its nominee, upon receipt of any such distributions, shall credit immediately DTC Participants’ accounts with payments in amounts proportionate to their respective beneficial interests in shares of each Fund as shown on the records of DTC or its nominee. Payments by DTC Participants to Indirect Participants and Beneficial Owners of shares held through such DTC Participants will be governed by standing instructions and customary practices, as is now the case with securities held for the accounts of customers in bearer form or registered in a “street name,” and will be the responsibility of such DTC Participants.

The Trust has no responsibility or liability for any aspect of the records relating to or notices to Beneficial Owners, or payments made on account of beneficial ownership interests in such shares, or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests, or for any other aspect of the relationship between DTC and the DTC Participants or the relationship between such DTC Participants and the Indirect Participants and Beneficial Owners owning through such DTC Participants. DTC may decide to discontinue providing its service with respect to shares of the Trust at any time by giving reasonable notice to the Trust and discharging its responsibilities with respect thereto under applicable law. Under such circumstances, the Trust shall take action to find a replacement for DTC to perform its functions at a comparable cost.

Creation and Redemption of Creation Units

General. The Trust issues and sells shares of each Fund only in Creation Units on a continuous basis through the Distributor, without a sales load, at a price based on the NAV next determined after receipt, on any Business Day (as defined below), of an order in proper form. The following table sets forth the number of shares of a Fund that constitute a Creation Unit for such Fund and the value of such Creation Unit as of September 30, 2011:

The Board reserves the right to declare a split or a consolidation in the number of shares outstanding of any Fund, and to make a corresponding change in the number of shares constituting a Creation Unit, in the event that the per share price in the secondary market rises (or declines) to an amount that falls outside the range deemed desirable by the Board.

A “Business Day” with respect to each Fund is any day on which the Listing Exchange on which the Fund is listed for trading is open for business. As of the date of this SAI, each Listing Exchange observes the following holidays, as observed: New Year’s Day, Martin Luther King, Jr. Day, Presidents’ Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day.

Fund Deposit. The consideration for purchase of Creation Units of a Fund generally consists of the in-kind deposit of a designated portfolio of securities (including any portion of such securities for which cash may be substituted) (i.e., the Deposit Securities) and the Cash Component computed as described below. Together, the Deposit Securities and the Cash Component constitute the “Fund Deposit,” which when combined with the Fund’s portfolio securities is designed to generate performance that has a collective investment profile similar to that of the Underlying Index. The Fund Deposit represents the minimum initial and subsequent investment amount for a Creation Unit of any Fund.

The Cash Component is an amount equal to the difference between the net asset value of the shares (per Creation Unit) and the “Deposit Amount,” which is an amount equal to the market value of the Deposit Securities, and serves to compensate for any differences between the net asset value per Creation Unit and the Deposit Amount. Payment of any stamp duty or other similar fees and expenses payable upon transfer of beneficial ownership of the Deposit Securities are the sole responsibility of the Authorized Participant purchasing a Creation Unit.

BFA makes available through the NSCC on each Business Day, prior to the opening of business on the Listing Exchange, the list of names and the required number of shares of each Deposit Security and the amount of the Cash Component to be included in the current Fund Deposit (based on information as of the end of the previous Business Day) for each Fund. Such Fund Deposit is applicable, subject to any adjustments as described below, in order to effect purchases of Creation Units of shares of a given Fund until such time as the next-announced Fund Deposit is made available.

The identity and number of shares of the Deposit Securities change pursuant to changes in the composition of a Fund’s portfolio and as rebalancing adjustments and corporate action events are reflected from time to time by BFA with a view to the investment objective of the Fund. The composition of the Deposit Securities may also change in response to adjustments to the weighting or composition of the component securities constituting the relevant Underlying Index.

The Funds reserve the right to permit or require the substitution of a “cash in lieu” amount to be added to the Cash Component to replace any Deposit Security that may not be available in sufficient quantity for delivery or that may not be eligible for transfer through DTC. The Funds also reserve the right to permit or require a “cash in lieu” amount in certain circumstances, including circumstances in which (i) the delivery of the Deposit Security by the Authorized Participant (as described below) would be restricted under applicable securities laws or (ii) the delivery of the Deposit Security to the Authorized Participant would result in the disposition of the Deposit Security by the Authorized Participant becoming restricted under applicable securities laws, or in certain other situations.

Role of the Authorized Participant. Creation Units may be purchased only by or through a DTC Participant that has entered into an Authorized Participant Agreement with the Distributor (an “Authorized Participant”). Such Authorized Participant will agree, pursuant to the terms of such Authorized Participant Agreement and on behalf of itself or any investor on whose behalf it will act, to certain conditions, including that such Authorized Participant will make available in advance of each purchase of shares an amount of cash sufficient to pay the Cash Component, once the net asset value of a Creation Unit is next determined after receipt of the purchase order in proper form, together with the transaction fee described below. The Authorized Participant may require the investor to enter into an agreement with such Authorized Participant with respect to certain matters, including payment of the Cash Component. Investors who are not Authorized Participants must make appropriate arrangements with an Authorized Participant. Investors should be aware that their particular broker may not be a DTC Participant or may not have executed an Authorized Participant Agreement and that orders to purchase Creation Units may have to be placed by the investor’s broker through an Authorized Participant. As a result, purchase orders placed through an Authorized Participant may result in additional charges to such investor. The Trust does not expect to enter into an Authorized Participant Agreement with more than a small number of DTC Participants. A list of current Authorized Participants may be obtained from the Distributor.

Purchase Orders. To initiate an order for a Creation Unit, an Authorized Participant must submit to the Distributor an irrevocable order to purchase shares of a Fund generally before 4:00 p.m., Eastern time on any Business Day to receive that day’s NAV. On days when the Listing Exchange closes earlier than normal, the Funds may require orders for Creation Units to be placed earlier in the day. The Distributor will notify BFA and the Custodian of such order. The Custodian will then provide such information to any appropriate subcustodian. Procedures and requirements governing the delivery of the Fund Deposit are set forth in the procedures handbook for Authorized Participants and may change from time to time. Those placing orders to purchase Creation Units through an Authorized Participant should allow sufficient time to permit proper submission of the purchase order to the Distributor by the Cutoff Time (as defined below) on such Business Day.

The Authorized Participant must also make available on or before the contractual settlement date, by means satisfactory to the Funds, immediately available or same day funds estimated by the Funds to be sufficient to pay the Cash Component next determined after acceptance of the purchase order, together with the applicable purchase transaction fees. Any excess funds

will be returned following settlement of the issue of the Creation Unit. Those placing orders should ascertain the applicable deadline for cash transfers by contacting the operations department of the broker or depositary institution effectuating the transfer of the Cash Component. This deadline is likely to be significantly earlier than the Cutoff Time (as described below) of the Funds.

The Authorized Participant is responsible for any and all expenses and costs incurred by a Fund, including any applicable cash amounts, in connection with any purchase order.

Investors, other than Authorized Participants, are responsible for making arrangements for a creation request to be made through an Authorized Participant. The Distributor will provide a list of current Authorized Participants upon request. Investors should be aware that an Authorized Participant may require orders for purchases of shares placed with it to be in the particular form required by the individual Authorized Participant.

Timing of Submission of Purchase Orders. An Authorized Participant must submit an irrevocable order to purchase shares of a Fund generally before 4:00 p.m., Eastern time on any Business Day in order to receive that day’s NAV. Orders to create shares of a Fund that are submitted on the Business Day immediately preceding a holiday or day (other than a weekend) when the equity markets in the relevant foreign market are closed may not be accepted. Each deadline specified above for the submission of purchase orders is referred to as that Fund’s “Cutoff Time.” The Distributor in its discretion may permit the submission of such orders and requests by or through an Authorized Participant at any time (including on days on which the Listing Exchange is not open for business) via communication through the facilities of the Distributor’s proprietary website maintained for this purpose. Purchase orders and redemption requests, if accepted by the Trust, will be processed based on the NAV next determined after such acceptance in accordance with the Trust’s standard Cutoff Times as provided in the Authorized Participant Agreement and disclosed in this SAI.

Acceptance of Orders for Creation Units. Subject to the conditions that (i) an irrevocable purchase order has been submitted by the Authorized Participant (either on its own or another investor’s behalf) and (ii) arrangements satisfactory to the Funds are in place for payment of the Cash Component and any other cash amounts which may be due, the Funds will accept the order, subject to each Fund’s right (and the right of the Distributor and BFA) to reject any order until acceptance.

Once a Fund has accepted an order, upon the next determination of the net asset value of the shares, the Fund will confirm the issuance of a Creation Unit, against receipt of payment, at such net asset value. The Distributor will then transmit a confirmation of acceptance to the Authorized Participant that placed the order.

Each Fund reserves the absolute right to reject or revoke a creation order transmitted to it by the Distributor if (i) the order is not in proper form; (ii) the investor(s), upon obtaining the shares ordered, would own 80% or more of the currently outstanding shares of the Fund; (iii) the Deposit Securities delivered do not conform to the identity and number of shares specified, as described above; (iv) acceptance of the Deposit Securities would have certain adverse tax consequences to the Fund; (v) acceptance of the Fund Deposit would, in the opinion of counsel, be unlawful; (vi) acceptance of the Fund Deposit would, in the discretion of the Fund or BFA, have an adverse effect on the Fund or the rights of beneficial owners; or (vii) circumstances outside the control of the Fund, the Distributor and BFA make it impracticable to process purchase orders. The Distributor shall notify a prospective purchaser of a Creation Unit and/or the Authorized Participant acting on behalf of such purchaser of its rejection of such order. The Funds, State Street, the subcustodian and the Distributor are under no duty, however, to give notification of any defects or irregularities in the delivery of Portfolio Deposits nor shall any of them incur any liability for failure to give such notification.

Issuance of a Creation Unit. Except as provided herein, a Creation Unit will not be issued until the transfer of good title to the Funds of the Deposit Securities and the payment of the Cash Component have been completed. When the subcustodian has confirmed to the Custodian that the securities included in the Fund Deposit (or the cash value thereof) have been delivered to the account of the relevant subcustodian or subcustodians, the Distributor and BFA shall be notified of such delivery and the applicable Fund will issue and cause the delivery of the Creation Unit. Creation Units typically are issued on a “T+3 basis” (i.e., three Business Days after trade date). For the iShares FTSE China 25 Index Fund and iShares FTSE China (HK Listed) Index Fund, Creation Units typically are issued on a “T+2 basis” (i.e., two Business Days after trade date). However, as discussed in the Regular Holidays section of this SAI, each Fund reserves the right to settle Creation Unit transactions on a basis other than T+3 in order to accommodate non-U.S. market holiday schedules, to account for different treatment among non-U.S. and U.S. markets of dividend record dates and ex-dividend dates (i.e., the last day the holder of a security can sell the security and still receive dividends payable on the security), and in certain other circumstances.

To the extent contemplated by an Authorized Participant’s agreement with the Distributor, each Fund will issue Creation Units to such Authorized Participant, notwithstanding the fact that the corresponding Portfolio Deposits have not been received in part or in whole, in reliance on the undertaking of the Authorized Participant to deliver the missing Deposit Securities as soon as possible, which undertaking shall be secured by such Authorized Participant’s delivery and maintenance of collateral having a value at least equal to 105% and up to 115%, which percentage BFA may change from time to time, of the value of the missing Deposit Securities in accordance with the Funds’ then-effective procedures. The only collateral that is acceptable to the Funds is cash in U.S. dollars. Such cash collateral must be delivered no later than 2:00 p.m., Eastern time on the contractual settlement date. The cash collateral posted by the Authorized Participant may be invested at the risk of the Authorized Participant, and income, if any, on invested cash collateral will be paid to that Authorized Participant. Information concerning the Funds’ current procedures for collateralization of missing Deposit Securities is available from the Distributor. The Authorized Participant Agreement will permit the Funds to buy the missing Deposit Securities at any time and will subject the Authorized Participant to liability for any shortfall between the cost to the Funds of purchasing such securities and the cash collateral.

In certain cases, Authorized Participants may create and redeem Creation Units on the same trade date and in these instances, the Funds reserve the right to settle these transactions on a net basis or require a representation from the Authorized Participants that the creation and redemption transactions are for separate beneficial owners. All questions as to the number of shares of each security in the Deposit Securities and the validity, form, eligibility and acceptance for deposit of any securities to be delivered shall be determined by each Fund and the Fund’s determination shall be final and binding.

Cash Purchase Method. Although the Trust does not ordinarily permit cash purchases of Creation Units of iShares funds, when Creation Units are available or specified for a Fund, they will be effected in essentially the same manner as in-kind purchases thereof. In the case of a cash purchase, the Authorized Participant must pay the cash equivalent of the Deposit Securities it would otherwise be required to provide through an in-kind purchase, plus the same Cash Component required to be paid by an in-kind purchaser.

Costs Associated with Creation Transactions. A standard creation transaction fee is imposed to offset the transfer and other transaction costs associated with the issuance of Creation Units. The standard creation transaction fee will be the same regardless of the number of Creation Units purchased by an Authorized Participant on the applicable Business Day. The Authorized Participant may also be required to cover certain brokerage, tax, foreign exchange, execution, market impact and other costs and expenses related to the execution of trades resulting from such transaction (up to the maximum amount shown below). Authorized Participants will also bear the costs of transferring the Deposit Securities to the Funds. Investors who use the services of a broker or other financial intermediary may be charged a fee for such services.

Redemption of Creation Units. Shares of a Fund may be redeemed by Authorized Participants only in Creation Units at their NAV next determined after receipt of a redemption request in proper form by the Distributor and only on a Business Day. The Funds will not redeem shares in amounts less than Creation Units. There can be no assurance, however, that there will be sufficient liquidity in the secondary market at any time to permit assembly of a Creation Unit. Investors should expect to incur brokerage and other costs in connection with assembling a sufficient number of shares to constitute a Creation Unit that could be redeemed by an Authorized Participant. Beneficial owners also may sell shares in the secondary market.

BFA makes available through the NSCC, prior to the opening of business on the Listing Exchange on each Business Day, the designated portfolio of securities (including any portion of such securities for which cash may be substituted) that will be applicable (subject to possible amendment or correction) to redemption requests received in proper form (as defined below) on that day (“Fund Securities”), and an amount of cash (as described below). Such Fund Securities and the corresponding cash amount are applicable, subject to any adjustments as described below, in order to effect redemptions of Creation Units of a Fund until such time as the next announced composition of the Fund Securities is made available. Fund Securities received on redemption may not be identical to Deposit Securities that are applicable to creations of Creation Units.

Unless cash redemptions are available or specified for a Fund, the redemption proceeds for a Creation Unit generally consist of Fund Securities, plus additional cash in an amount equal to the difference between the net asset value of the shares being redeemed, as next determined after the receipt of a request in proper form, and the value of Fund Securities, less a redemption transaction fee (as described below). The Trust may, in its sole discretion, substitute a “cash in lieu” amount to replace any Fund Security. The amount of cash paid out in such cases will be equivalent to the value of the substituted security listed as a Fund Security. In the event that the Fund Securities have a value greater than the NAV of the shares, a compensating cash payment equal to the difference is required to be made by or through an Authorized Participant by the redeeming shareholder. Each Fund currently redeems shares for Fund Securities, but each Fund reserves the right to utilize a cash option for redemption of shares.

Costs Associated with Redemption Transactions. A standard redemption transaction fee is imposed to offset transfer and other transaction costs that may be incurred by the relevant Fund. The standard redemption transaction fee will be the same regardless of the number of Creation Units redeemed by an Authorized Participant on the applicable Business Day. The Authorized Participant may also be required to cover certain brokerage, tax, foreign exchange, execution, market impact and other costs and expenses related to the execution of trades resulting from such transaction (up to the maximum amount shown below). Authorized Participants will also bear the costs of transferring the Fund Securities from a Fund to their account on their order. Investors who use the services of a broker or other financial intermediary may be charged a fee for such services.

Placement of Redemption Orders. Redemption requests for Creation Units of any Fund must be submitted to the Distributor by or through an Authorized Participant. An Authorized Participant must submit an irrevocable request to redeem shares of a Fund generally before 4:00 p.m., Eastern time on any Business Day, in order to receive that day’s NAV. Orders to redeem shares of each Fund that are submitted on the Business Day immediately preceding a holiday or day (other than a weekend) when the equity markets in the relevant foreign market are closed may not be accepted. Investors other than Authorized Participants are responsible for making arrangements for a redemption request to be made through an Authorized Participant. The Distributor will provide a list of current Authorized Participants upon request.

The Authorized Participant must transmit the request for redemption in the form required by the Funds to the Distributor in accordance with procedures set forth in the Authorized Participant Agreement. Investors should be aware that their particular broker may not have executed an Authorized Participant Agreement and that, therefore, requests to redeem Creation Units may have to be placed by the investor’s broker through an Authorized Participant who has executed an Authorized Participant Agreement. At any time, only a limited number of broker-dealers will have an Authorized Participant Agreement in effect. Investors making a redemption request should be aware that such request must be in the form specified by such Authorized Participant. Investors making a request to redeem Creation Units should allow sufficient time to permit proper submission of the request by an Authorized Participant and transfer of the shares to the Funds’ Transfer Agent; such

investors should allow for the additional time that may be required to effect redemptions through their banks, brokers or other financial intermediaries if such intermediaries are not Authorized Participants.

A redemption request is considered to be in “proper form” if (i) an Authorized Participant has transferred or caused to be transferred to the Funds’ Transfer Agent the Creation Unit being redeemed through the book-entry system of DTC so as to be effective by the Listing Exchange closing time on any Business Day, (ii) a request in form satisfactory to the applicable Fund is received by the Distributor from the Authorized Participant on behalf of itself or another redeeming investor within the time periods specified above and (iii) all other procedures set forth in the Authorized Participant Agreement are properly followed. If the Transfer Agent does not receive the investor’s shares through DTC’s facilities by 10:00 a.m., Eastern time on the Business Day next following the day that the redemption request is received, the redemption request shall be rejected. Investors should be aware that the deadline for such transfers of shares through the DTC system may be significantly earlier than the close of business on the Listing Exchange. Those making redemption requests should ascertain the deadline applicable to transfers of shares through the DTC system by contacting the operations department of the broker or depositary institution effecting the transfer of the shares.

Upon receiving a redemption request, the Distributor shall notify the applicable Fund and the Fund’s Transfer Agent of such redemption request. The tender of an investor’s shares for redemption and the distribution of the securities and/or cash included in the redemption payment made in respect of Creation Units redeemed will be made through DTC and the relevant Authorized Participant to the Beneficial Owner thereof as recorded on the book-entry system of DTC or the DTC Participant through which such investor holds, as the case may be, or by such other means specified by the Authorized Participant submitting the redemption request.

A redeeming Beneficial Owner or Authorized Participant acting on behalf of such Beneficial Owner must maintain appropriate security arrangements with a qualified broker-dealer, bank or other custody providers in each jurisdiction in which any of the Portfolio Securities are customarily traded, to which account such Portfolio Securities will be delivered.

Deliveries of redemption proceeds by the Funds generally will be made within three Business Days (i.e., “T+3”). For the iShares FTSE China 25 Index Fund and iShares FTSE China (HK Listed) Index Fund, deliveries of redemption proceeds generally will be made within two Business Days (i.e., “T+2”). However, as discussed in the Regular Holidays section, each Fund reserves the right to settle redemption transactions and deliver redemption proceeds on another basis to accommodate non-U.S. market holiday schedules, to account for different treatment among non-U.S. and U.S. markets of dividend record dates and dividend ex-dates (i.e., the last date the holder of a security can sell the security and still receive dividends payable on the security sold) and in certain other circumstances. The Regular Holidays section hereto identifies the instances, if any, where more than seven days would be needed to deliver redemption proceeds. Pursuant to an order of the SEC, the Trust will make delivery of redemption proceeds within the number of days stated in the Regular Holidays section to be the maximum number of days necessary to deliver redemption proceeds.


If neither the redeeming Beneficial Owner nor the Authorized Participant acting on behalf of such redeeming Beneficial Owner has appropriate arrangements to take delivery of Fund Securities in the applicable non-U.S. jurisdiction and it is not possible to make other such arrangements, or if it is not possible to effect deliveries of Fund Securities in such jurisdiction, a Fund may in its discretion exercise its option to redeem such shares in cash, and the redeeming Beneficial Owner will be required to receive its redemption proceeds in cash. In such case, the investor will receive a cash payment equal to the net asset value of its shares based on the net asset value of shares of the relevant Fund next determined after the redemption request is received in proper form (minus a redemption transaction fee and additional charges specified above to offset the Fund’s brokerage and other transaction costs associated with the disposition of Fund securities). Redemptions of shares for Fund Securities will be subject to compliance with applicable U.S. federal and state securities laws and each Fund (whether or not it otherwise permits cash redemptions) reserves the right to redeem Creation Units for cash to the extent that the Fund cannot lawfully deliver specific Fund Securities upon redemptions or cannot do so without first registering the Fund Securities under such laws.


Although the Trust does not ordinarily permit cash redemptions of Creation Units, in the event that cash redemptions are permitted or required by the Trust, proceeds will be paid to the Authorized Participant redeeming shares as soon as practicable after the date of redemption (within seven calendar days thereafter, except for the instances listed in the Regular Holidays section in which more than seven calendar days would be needed).

To the extent contemplated by an Authorized Participant’s agreement with the Distributor, in the event an Authorized Participant has submitted a redemption request in proper form but is unable to transfer all or part of the Creation Unit to be redeemed to the Fund, at or prior to 10:00 a.m., Eastern time on the Listing Exchange business day after the date of

submission of such redemption request, the Distributor will accept the redemption request in reliance on the undertaking by the Authorized Participant to deliver the missing shares as soon as possible. Such undertaking shall be secured by the Authorized Participant’s delivery and maintenance of collateral consisting of cash, in U.S. dollars in immediately available funds, having a value at least equal to 105% and up to 115%, which percentage BFA may change from time to time, of the value of the missing shares. Such cash collateral must be delivered no later than 10:00 a.m., Eastern time on the day after the date of submission of such redemption request and shall be held by State Street and marked-to-market daily. The fees of State Street and any subcustodians in respect of the delivery, maintenance and redelivery of the cash collateral shall be payable by the Authorized Participant. The cash collateral posted by the Authorized Participant may be invested at the risk of the Authorized Participant, and income, if any, on invested cash collateral will be paid to that Authorized Participant. The Authorized Participant Agreement permits the Funds to acquire Fund Securities and the Cash Component underlying such shares at any time and subjects the Authorized Participant to liability for any shortfall between the cost to the Funds of purchasing such shares, Fund Securities or Cash Component and the value of the cash collateral.

Because the Portfolio Securities of a Fund may trade on exchange(s) on days that the Listing Exchange is closed or are otherwise not Business Days for such Fund, shareholders may not be able to redeem their shares of such Fund, or purchase or sell shares of such Fund on the Listing Exchange on days when the NAV of such a Fund could be significantly affected by events in the relevant non-U.S. markets.

The right of redemption may be suspended or the date of payment postponed with respect to any Fund (i) for any period during which the applicable Listing Exchange is closed (other than customary weekend and holiday closings), (ii) for any period during which trading on the applicable Listing Exchange is suspended or restricted, (iii) for any period during which an emergency exists as a result of which disposal of the shares of the Fund’s portfolio securities or determination of its net asset value is not reasonably practicable; or (iv) in such other circumstance as is permitted by the SEC.

Taxation on Creation and Redemptions of Creation Units. An Authorized Participant generally will recognize either gain or loss upon the exchange of Deposit Securities for Creation Units. This gain or loss is calculated by taking the market value of the Creation Units purchased over the Authorized Participant’s aggregate basis in the Deposit Securities exchanged therefor. However, the U.S. Internal Revenue Service (the “IRS”) may apply the wash sales rules to determine that any loss realized upon the exchange of Deposit Securities for Creation Units is not currently deductible. Authorized Participants should consult their own tax advisors.

Current U.S. federal tax laws dictate that capital gain or loss realized from the redemption of Creation Units will generally create long-term capital gain or loss if the Authorized Participant holds the Creation Units for more than one year, or short-term capital gain or loss if the Creation Units were held for one year or less, if the Creation Units are held as capital assets.

Regular Holidays. For every occurrence of one or more intervening holidays in the applicable non-U.S. market that are not holidays observed in the U.S. equity market, the redemption settlement cycle will be extended by the number of such intervening holidays. In addition to holidays, other unforeseeable closings in a non-U.S. market due to emergencies may also prevent the Trust from delivering securities within normal settlement period.

The securities delivery cycles currently practicable for transferring portfolio securities to redeeming investors, coupled with non-U.S. market holiday schedules, will require a delivery process longer than seven calendar days, in certain circumstances. The holidays applicable to each Fund during such periods are listed below, as are instances where more than seven days will be needed to deliver redemption proceeds. Although certain holidays may occur on different dates in subsequent years, the number of days required to deliver redemption proceeds in any given year is not expected to exceed the maximum number of days listed below for each Fund. The proclamation of new holidays, the treatment by market participants of certain days as “informal holidays” (e.g., days on which no or limited securities transactions occur, as a result of substantially shortened trading hours), the elimination of existing holidays, or changes in local securities delivery practices, could affect the information set forth herein at some time in the future.

In calendar years 2011 and 2012, the dates of regular holidays affecting the relevant securities markets in which a Fund invests are as follows (please note these holiday schedules are subject to potential changes in the relevant securities markets):

Taxes

Regulated Investment Company Qualifications. Each Fund intends to continue to qualify for treatment as a separate RIC under Subchapter M of the Internal Revenue Code. To qualify for treatment as a RIC, each Fund must annually distribute at least 90% of its investment company taxable income (which includes dividends, interest and net short-term capital gains) and meet several other requirements. Among such other requirements are the following: (i) at least 90% of each Fund’s annual gross income must be derived from dividends, interest, payments with respect to securities loans, gains from the sale or other disposition of stock or securities or non-U.S. currencies, other income (including, but not limited to, gains from options, futures or forward contracts) derived with respect to its business of investing in such stock, securities or currencies, and net income derived from interests in qualified publicly-traded partnerships (i.e., partnerships that are traded on an established securities market or tradable on a secondary market, other than partnerships that derive 90% of their income from interest, dividends, capital gains and other traditionally permitted mutual fund income); and (ii) at the close of each quarter of each Fund’s taxable year, (a) at least 50% of the market value of each Fund’s total assets must be represented by cash and cash items, U.S. government securities, securities of other RICs and other securities, with such other securities limited for purposes of this calculation in respect of any one issuer to an amount not greater than 5% of the value of the Fund’s assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of each Fund’s total assets may be invested in the securities (other than U.S. government securities or the securities of other RICs) of any one issuer, of two or more issuers of which 20% or more of the voting stock is held by the Fund and that are engaged in the same or similar trades or businesses or related trades or businesses, or the securities of one or more qualified publicly-traded partnerships.

Although, in general, the passive loss rules of the Internal Revenue Code do not apply to RICs, such rules do apply to a RIC with respect to items attributable to interests in qualified publicly-traded partnerships. A Fund’s investments in partnerships, including in qualified publicly-traded partnerships, may result in a Fund being subject to state, local, or non-U.S. income, franchise or withholding tax liabilities.

Taxation of RICs. As a RIC, a Fund will not be subject to U.S. federal income tax on the portion of its taxable investment income and capital gains that it distributes to its shareholders, provided that it satisfies a minimum distribution requirement. To satisfy the minimum distribution requirement, a Fund must distribute to its shareholders at least the sum of (i) 90% of its “investment company taxable income” (i.e., income other than its net realized long-term capital gain over its net realized short-term capital loss), plus or minus certain adjustments, and (ii) 90% of its net tax-exempt income for the taxable year. A Fund will be subject to income tax at regular corporate rates on any taxable income or gains that it does not distribute to its shareholders. If a Fund fails to qualify for any taxable year as a RIC or fails to meet the distribution requirement, all of its taxable income will be subject to tax at regular corporate income tax rates without any deduction for distributions to shareholders, and such distributions generally will be taxable to shareholders as ordinary dividends to the extent of the Fund’s current and accumulated earnings and profits. In such event, distributions to individuals should be eligible to be treated as qualified dividend income and distributions to corporate shareholders generally should be eligible for the dividends received deduction. Although each Fund intends to distribute substantially all of its net investment income and its capital gains for each taxable year, each Fund will be subject to U.S. federal income taxation to the extent any such income or gains are not distributed. If a Fund fails to qualify as a RIC in any year, it must pay out its earnings and profits accumulated in that year in order to qualify again as a RIC. If a Fund fails to qualify as a RIC for a period greater than two taxable years, the Fund may be required to recognize any net built-in gains with respect to certain of its assets (i.e., the excess of the aggregate gains, including items of income, over aggregate losses that would have been realized with respect to such assets if the Fund had been liquidated) if it qualifies as a RIC in a subsequent year.

Excise Tax. A Fund will be subject to a 4% excise tax on certain undistributed income if it does not distribute to its shareholders in each calendar year at least 98% of its ordinary income for the calendar year plus 98.2% of its capital gain net income for the 12 months ended October 31 of such year. For this purpose, however, any ordinary income or capital gain net income retained by a Fund that is subject to corporate income tax will be considered to have been distributed by year-end. In

addition, the minimum amounts that must be distributed in any year to avoid the excise tax will be increased or decreased to reflect any underdistribution or overdistribution, as the case may be, from the previous year. Each Fund intends to declare and distribute dividends and distributions in the amounts and at the times necessary to avoid the application of this 4% excise tax.

Net Capital Loss Carryforwards. Net capital loss carryforwards may be applied against any net realized capital gains in each succeeding year, until they have been reduced to zero or until their respective expiration dates, whichever occurs first. Capital loss carryforwards from taxable years beginning after December 2010 are not subject to expiration.

The following Funds had tax basis net capital loss carryforwards as of July 31, 2011, the tax year-end for the Funds listed:

Taxation of U.S. Shareholders. Dividends and other distributions by a Fund are generally treated under the Internal Revenue Code as received by the shareholders at the time the dividend or distribution is made. However, any dividend or distribution declared by a Fund in October, November or December of any calendar year and payable to shareholders of record on a specified date in such a month shall be deemed to have been received by each shareholder on December 31 of such calendar year and to have been paid by the Fund not later than such December 31, provided such dividend is actually paid by the Fund during January of the following calendar year.

Each Fund intends to distribute annually to its shareholders substantially all of its investment company taxable income and any net realized long-term capital gains in excess of net realized short-term capital losses (including any capital loss carryovers). However, if a Fund retains for investment an amount equal to all or a portion of its net long-term capital gains in excess of its net short-term capital losses (including any capital loss carryovers), it will be subject to a corporate tax (currently at a maximum rate of 35%) on the amount retained. In that event, the Fund will designate such retained amounts as undistributed capital gains in a notice to its shareholders who (a) will be required to include in income for U.S. federal income tax purposes, as long-term capital gains, their proportionate shares of the undistributed amount, (b) will be entitled to credit their proportionate shares of the 35% tax paid by the Fund on the undistributed amount against their U.S. federal income tax liabilities, if any, and to claim refunds to the extent their credits exceed their liabilities, if any, and (c) will be entitled to increase their tax basis, for U.S. federal income tax purposes, in their shares by an amount equal to 65% of the amount of undistributed capital gains included in the shareholder’s income. Organizations or persons not subject to U.S. federal income tax on such capital gains will be entitled to a refund of their pro rata share of such taxes paid by the Fund upon filing appropriate returns or claims for refund with the IRS.

Distributions of net realized long-term capital gains, if any, that a Fund reports as capital gains dividends are taxable as long-term capital gains, whether paid in cash or in shares and regardless of how long a shareholder has held shares of the Fund. All other dividends of a Fund (including dividends from short-term capital gains) from its current and accumulated earnings and profits (“regular dividends”) are generally subject to tax as ordinary income, subject to the discussion of qualified dividend income below.

If an individual receives a regular dividend qualifying for the long-term capital gains rates and such dividend constitutes an “extraordinary dividend,” and the individual subsequently recognizes a loss on the sale or exchange of stock in respect of which the extraordinary dividend was paid, then the loss will be long-term capital loss to the extent of such extraordinary dividend. An “extraordinary dividend” on common stock for this purpose is generally a dividend (i) in an amount greater than or equal to 10% of the taxpayer’s tax basis (or trading value) in a share of stock, aggregating dividends with ex-dividend dates within an 85-day period, or (ii) in an amount greater than 20% of the taxpayer’s tax basis (or trading value) in a share of stock, aggregating dividends with ex-dividend dates within a 365-day period.

Distributions in excess of a Fund’s current and accumulated earnings and profits will, as to each shareholder, be treated as a tax-free return of capital to the extent of a shareholder’s basis in shares of the Fund, and as a capital gain thereafter (if the shareholder holds shares of the Fund as capital assets). Shareholders receiving dividends or distributions in the form of additional shares should be treated for U.S. federal income tax purposes as receiving a distribution in an amount equal to the amount of money that the shareholders receiving cash dividends or distributions will receive and should have a cost basis in the shares received equal to such amount. Dividends paid by a Fund that are attributable to dividends received by a Fund from domestic corporations may qualify for the federal dividends received deduction for corporations.

Beginning in 2013, a 3.8% U.S. federal Medicare contribution tax will be imposed on net investment income, including interest, dividends, and capital gain, of U.S. individuals with income exceeding $200,000 (or $250,000 if married and filing jointly), and of estates and trusts.

Investors considering buying shares just prior to a dividend or capital gain distribution should be aware that, although the price of shares purchased at that time may reflect the amount of the forthcoming distribution, such dividend or distribution may nevertheless be taxable to them. If a Fund is the holder of record of any security on the record date for any dividends payable with respect to such security, such dividends will be included in the Fund’s gross income not as of the date received but as of the later of (a) the date such security became ex-dividend with respect to such dividends (i.e., the date on which a buyer of the security would not be entitled to receive the declared, but unpaid, dividends); or (b) the date the Fund acquired such security. Accordingly, in order to satisfy its income distribution requirements, a Fund may be required to pay dividends based on anticipated earnings, and shareholders may receive dividends in an earlier year than would otherwise be the case.

In certain situations, a Fund may, for a taxable year, defer all or a portion of its capital losses and currency losses realized after October and certain ordinary losses realized after December until the next taxable year in computing its investment company taxable income and net capital gain, which will defer the recognition of such realized losses. Such deferrals and other rules regarding gains and losses realized after October (or December) may affect the tax character of shareholder distributions.

Sales of Shares. Upon the sale or exchange of shares of a Fund, a shareholder will realize a taxable gain or loss equal to the difference between the amount realized and the shareholder’s basis in shares of the Fund. A redemption of shares by a Fund will be treated as a sale for this purpose. Such gain or loss will be treated as capital gain or loss if the shares are capital assets in the shareholder’s hands and will be long-term capital gain or loss if the shares are held for more than one year and short-term capital gain or loss if the shares are held for one year or less. Any loss realized on a sale or exchange will be disallowed to the extent the shares disposed of are replaced, including replacement through the reinvesting of dividends and capital gains distributions in the Funds, within a 61-day period beginning 30 days before and ending 30 days after the disposition of the shares. In such a case, the basis of the shares acquired will be increased to reflect the disallowed loss. Any loss realized by a shareholder on the sale of Fund shares held by the shareholder for six months or less will be treated for U.S. federal income tax purposes as a long-term capital loss to the extent of any distributions or deemed distributions of long-term capital gains received by the shareholder with respect to such share. The Medicare contribution tax described above will apply to the sale of Fund shares.

If a shareholder incurs a sales charge in acquiring shares of a Fund, disposes of those shares within 90 days and then, on or before January 31 of the following calendar year, acquires shares in a mutual fund for which the otherwise applicable sales charge is reduced by reason of a reinvestment right (e.g., an exchange privilege), the original sales charge will not be taken into account in computing gain/loss on the original shares to the extent the subsequent sales charge is reduced. Instead, the disregarded portion of the original sales charge will be added to the tax basis of the newly acquired shares. Furthermore, the same rule also applies to a disposition of the newly acquired shares made within 90 days of the second acquisition. This provision prevents shareholders from immediately deducting the sales charge by shifting their investments within a family of mutual funds.

Back-Up Withholding. In certain cases, a Fund will be required to withhold at the applicable withholding rate, and remit to the U.S. Treasury such amounts withheld from any distributions paid to a shareholder who: (i) has failed to provide a correct taxpayer identification number; (ii) is subject to back-up withholding by the IRS; (iii) has failed to certify to a Fund that such shareholder is not subject to back-up withholding; or (iv) has not certified that such shareholder is a U.S. person (including a U.S. resident alien). Back-up withholding is not an additional tax and any amount withheld may be credited against a shareholder’s U.S. federal income tax liability.

Sections 351 and 362. The Trust, on behalf of each Fund, has the right to reject an order for a purchase of shares of the Fund if the purchaser (or group of purchasers) would, upon obtaining the shares so ordered, own 80% or more of the outstanding shares of a given Fund and if, pursuant to Sections 351 and 362 of the Internal Revenue Code, that Fund would have a basis in the securities different from the market value of such securities on the date of deposit. If a Fund’s basis in such securities on the date of deposit was less than market value on such date, the Fund, upon disposition of the securities, would recognize more taxable gain or less taxable loss than if its basis in the securities had been equal to market value. It is not anticipated that the Trust will exercise the right of rejection except in a case where the Trust determines that accepting the order could result in material adverse tax consequences to a Fund or its shareholders. The Trust also has the right to require information necessary to determine beneficial share ownership for purposes of the 80% determination.


Taxation of Certain Derivatives. A Fund’s transactions in zero coupon securities, non-U.S. currencies, forward contracts, options and futures contracts (including options and futures contracts on non-U.S. currencies), to the extent permitted, will be subject to special provisions of the Internal Revenue Code (including provisions relating to “hedging transactions” and “straddles”) that, among other things, may affect the character of gains and losses realized by the Fund (i.e., may affect whether gains or losses are ordinary or capital), accelerate recognition of income to the Fund and defer Fund losses. These rules could therefore affect the character, amount and timing of distributions to shareholders. These provisions also (a) will require a Fund to mark-to-market certain types of the positions in its portfolio (i.e., treat them as if they were closed out at the end of each year) and (b) may cause a Fund to recognize income without receiving cash with which to pay dividends or make distributions in amounts necessary to satisfy the distribution requirements for avoiding income and excise taxes. Each Fund will monitor its transactions, will make the appropriate tax elections and will make the appropriate entries in its books and records when it acquires any zero coupon security, non-U.S. currency, forward contract, option, futures contract or hedged investment in order to mitigate the effect of these rules and prevent disqualification of the Fund as a RIC.

A Fund’s investments in so-called “Section 1256 contracts,” such as regulated futures contracts, most non-U.S. currency forward contracts traded in the interbank market and options on most security indexes, are subject to special tax rules. All Section 1256 contracts held by a Fund at the end of its taxable year are required to be marked to their market value, and any unrealized gain or loss on those positions will be included in the Fund’s income as if each position had been sold for its fair market value at the end of the taxable year. The resulting gain or loss will be combined with any gain or loss realized by the Fund from positions in Section 1256 contracts closed during the taxable year. Provided such positions were held as capital assets and were not part of a “hedging transaction” nor part of a “straddle,” 60% of the resulting net gain or loss will be treated as long-term capital gain or loss, and 40% of such net gain or loss will be treated as short-term capital gain or loss, regardless of the period of time the positions were actually held by the Fund.

As a result of entering into swap contracts, a Fund may make or receive periodic net payments. A Fund may also make or receive a payment when a swap is terminated prior to maturity through an assignment of the swap or other closing transaction. Periodic net payments will generally constitute ordinary income or deductions, while termination of a swap will generally result in capital gain or loss (which will be a long-term capital gain or loss if the Fund has been a party to the swap for more than one year). With respect to certain types of swaps, a Fund may be required to currently recognize income or loss with respect to future payments on such swaps or may elect under certain circumstances to mark such swaps to market annually for tax purposes as ordinary income or loss.

Qualified Dividend Income. Distributions by a Fund of investment company taxable income (including any short-term capital gains), whether received in cash or shares, will be taxable either as ordinary income or as qualified dividend income, eligible for the reduced maximum rate to individuals of 15% (0% for individuals in lower tax brackets) to the extent the Fund receives qualified dividend income on the securities it holds and the Fund reports the distribution as qualified dividend income. Qualified dividend income is, in general, dividend income from taxable U.S. corporations (but generally not from U.S. REITs) and certain non-U.S. corporations (e.g., non-U.S. corporations that are not “passive foreign investment companies” and which are incorporated in a possession of the United States or in certain countries with a comprehensive tax treaty with the United States, or the stock of which is readily tradable on an established securities market in the United States (where the dividends are paid with respect to such stock)). Under current IRS guidance, the United States has appropriate comprehensive income tax treaties with the following countries: Australia, Austria, Bangladesh, Barbados, Belgium, Bulgaria, Canada, China (but not with Hong Kong, which is treated as a separate jurisdiction for U.S. tax purposes), Cyprus, the Czech Republic, Denmark, Egypt, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, India, Indonesia, Ireland, Israel, Italy, Jamaica, Japan, Kazakhstan, Latvia, Lithuania, Luxembourg, Malta, Mexico, Morocco, the Netherlands, New Zealand, Norway,

Pakistan, the Philippines, Poland, Portugal, Romania, Russia, the Slovak Republic, Slovenia, South Africa, South Korea, Spain, Sri Lanka, Sweden, Switzerland, Thailand, Trinidad and Tobago, Tunisia, Turkey, Ukraine, the United Kingdom, and Venezuela. Substitute payments received by a Fund for securities lent out by the Fund will not be qualified dividend income.

A dividend from a Fund will not be treated as qualified dividend income to the extent that (i) the shareholder has not held the shares on which the dividend was paid for 61 days during the 121-day period that begins on the date that is 60 days before the date on which the shares become ex-dividend with respect to such dividend or the Fund fails to satisfy those holding period requirements with respect to the securities it holds that paid the dividends distributed to the shareholder (or, in the case of certain preferred stocks, the holding requirement of 91 days during the 181-day period beginning on the date that is 90 days before the date on which the stock becomes ex-dividend with respect to such dividend); (ii) the Fund or the shareholder is under an obligation (whether pursuant to a short sale or otherwise) to make related payments with respect to substantially similar or related property; or (iii) the shareholder elects to treat such dividend as investment income under Section 163(d)(4)(B) of the Internal Revenue Code. Dividends received by a Fund from a REIT or another RIC may be treated as qualified dividend income only to the extent the dividend distributions are attributable to qualified dividend income received by such REIT or other RIC. It is expected that dividends received by a Fund from a REIT and distributed to a shareholder generally will be taxable to the shareholder as ordinary income. The maximum 15% rate on qualified dividend income will not apply to dividends received in taxable years beginning after December 31, 2012. Distributions by a Fund of its net short-term capital gains will be taxable as ordinary income. Capital gain distributions consisting of a Fund’s net capital gains will be taxable as long-term capital gains.

If you lend your Fund shares pursuant to securities lending arrangements, you may lose the ability to use non-U.S. tax credits passed through by the Fund or to treat Fund dividends (paid while the shares are held by the borrower) as qualified dividends. Consult your financial intermediary or tax advisor. If you enter into a short sale with respect to shares of the Fund, substitute payments made to the lender of such shares may not be deductible. Consult your financial intermediary or tax advisor.

Corporate Dividends Received Deduction. Dividends paid by a Fund that are attributable to dividends received by the Fund from U.S. corporations may qualify for the U.S. federal dividends received deduction for corporations. A 46-day minimum holding period during the 90-day period that begins 45 days prior to ex-dividend date (or 91-day minimum holding period during the 180 period beginning 90 days prior to ex-dividend date for certain preference dividends) during which risk of loss may not be diminished is required for the applicable shares, at both the Fund and shareholder level, for a dividend to be eligible for the dividends received deduction. Restrictions may apply if indebtedness, including a short sale, is attributable to the investment.

Excess Inclusion Income. Under current law, the Funds serve to block unrelated business taxable income from being realized by their tax-exempt shareholders. Notwithstanding the foregoing, a tax-exempt shareholder could realize unrelated business taxable income by virtue of its investment in a Fund if shares in the Fund constitute debt-financed property in the hands of the tax-exempt shareholder within the meaning of Section 514(b) of the Internal Revenue Code. Certain types of income received by a Fund from REITs, real estate mortgage investment conduits, taxable mortgage pools or other investments may cause the Fund to report some or all of its distributions as “excess inclusion income.” To Fund shareholders, such excess inclusion income may (i) constitute taxable income, as unrelated business taxable income for those shareholders who would otherwise be tax-exempt such as individual retirement accounts, 401(k) accounts, Keogh plans, pension plans and certain charitable entities; (ii) not be offset by otherwise allowable deductions for tax purposes; (iii) not be eligible for reduced U.S. withholding for non-U.S. shareholders even from tax treaty countries; and (iv) cause the Fund to be subject to tax if certain “disqualified organizations,” as defined by the Internal Revenue Code, are Fund shareholders. If a charitable remainder annuity trust or a charitable remainder unitrust (each as defined in Section 664 of the Internal Revenue Code) has unrelated business taxable income (“UBTI”) for a taxable year, a 100% excise tax on the UBTI is imposed on the trust.

Non-U.S. Investments. Under Section 988 of the Internal Revenue Code, gains or losses attributable to fluctuations in exchange rates between the time a Fund accrues income or receivables or expenses or other liabilities denominated in a non-U.S. currency and the time the Fund actually collects such income or pays such liabilities are generally treated as ordinary income or ordinary loss. In general, gains (and losses) realized on debt instruments will be treated as Section 988 gain (or loss) to the extent attributable to changes in exchange rates between the U.S. dollar and the currencies in which the instruments are denominated. Similarly, gains or losses on non-U.S. currency, non-U.S. currency forward contracts and

certain non-U.S. currency options or futures contracts denominated in non-U.S currency, to the extent attributable to fluctuations in exchange rates between the acquisition and disposition dates, are also treated as ordinary income or loss unless the Fund were to elect otherwise.

Each Fund may be subject to non-U.S. income taxes withheld at the source. Each Fund, if permitted to do so, may elect to “pass through” to its investors the amount of non-U.S. income taxes paid by the Fund provided that the Fund held the security on the dividend settlement date and for at least 15 additional days immediately before and/or thereafter, with the result that each investor with respect to shares of the Fund held for a minimum 16-day holding period at the time of deemed distribution will (i) include in gross income, even though not actually received, the investor’s pro rata share of the Fund’s non-U.S. income taxes, and (ii) either deduct (in calculating U.S. taxable income, but only for investors who itemize their deductions on their personal tax returns) or credit (in calculating U.S. federal income tax) the investor’s pro rata share of the Fund’s non-U.S. income taxes. A non-U.S. person invested in a Fund in a year that the Fund elects to “pass through” its non-U.S. taxes may be treated as receiving additional dividend income subject to U.S. withholding tax. A non-U.S. tax credit may not exceed the investor’s U.S. federal income tax otherwise payable with respect to the investor’s non-U.S. source income. For this purpose, shareholders must treat as non-U.S. source gross income (i) their proportionate shares of non-U.S. taxes paid by the Fund and (ii) the portion of any dividend paid by the Fund that represents income derived from non-U.S. sources; the Fund’s gain from the sale of securities will generally be treated as U.S.-source income. Certain limitations will be imposed to the extent to which the non-U.S. tax credit may be claimed.

Passive Foreign Investment Companies. If a Fund purchases shares in “passive foreign investment companies” (“PFICs”), it may be subject to U.S. federal income tax on a portion of any “excess distribution” or gain from the disposition of such shares even if such income is distributed as a taxable dividend by the Fund to its shareholders. Additional charges in the nature of interest may be imposed on the Fund in respect of deferred taxes arising from such distributions or gains.

If a Fund were to invest in a PFIC and elect to treat the PFIC as a “qualified electing fund” under the Internal Revenue Code, in lieu of the foregoing requirements, the Fund might be required to include in income each year a portion of the ordinary earnings and net capital gains of the qualified electing fund, even if not distributed to the Fund, and such amounts would be subject to the 90% and excise tax distribution requirements described above. In order to make this election, the Fund would be required to obtain certain annual information from the PFICs in which it invests, which may be difficult or impossible to obtain.

Alternatively, a Fund may make a mark-to-market election that would result in the Fund being treated as if it had sold and repurchased its PFIC stock at the end of each year. In such case, the Fund would report any such gains as ordinary income and would deduct any such losses as ordinary losses to the extent of previously recognized gains. The election must be made separately for each PFIC owned by the Fund and, once made, would be effective for all subsequent taxable years, unless revoked with the consent of the IRS. By making the election, the Fund could potentially ameliorate the adverse tax consequences with respect to its ownership of shares in a PFIC, but in any particular year may be required to recognize income in excess of the distributions it receives from PFICs and its proceeds from dispositions of PFIC stock. The Fund may have to distribute this “phantom” income and gain to satisfy the 90% distribution requirement and to avoid imposition of the 4% excise tax.

A Fund will make the appropriate tax elections, if possible, and take any additional steps that are necessary to mitigate the effects of these rules.

Reporting. If a shareholder recognizes a loss with respect to a Fund’s shares of $2 million or more for an individual shareholder or $10 million or more for a corporate shareholder, the shareholder must file with the IRS a disclosure statement on Form 8886. Direct shareholders of portfolio securities are in many cases exempted from this reporting requirement, but under current guidance, shareholders of a RIC are not exempted. The fact that a loss is reportable under these regulations does not affect the legal determination of whether the taxpayer’s treatment of the loss is proper. Shareholders should consult their tax advisors to determine the applicability of these regulations in light of their individual circumstances.

Other Taxes. Dividends, distributions and redemption proceeds may also be subject to additional state, local and non-U.S. taxes depending on each shareholder’s particular situation.

Taxation of Non-U.S. Shareholders. Dividends paid by a Fund to non-U.S. shareholders are generally subject to withholding tax at a 30% rate or a reduced rate specified by an applicable income tax treaty to the extent derived from investment income and short-term capital gains. Dividends paid by a Fund from net tax-exempt income or long-term capital gains are generally

not subject to such withholding tax. In order to obtain a reduced rate of withholding, a non-U.S. shareholder will be required to provide an IRS Form W-8BEN certifying its entitlement to benefits under a treaty. The withholding tax does not apply to regular dividends paid to a non-U.S. shareholder who provides a Form W-8ECI, certifying that the dividends are effectively connected with the non-U.S. shareholder’s conduct of a trade or business within the United States. Instead, the effectively connected dividends will be subject to regular U.S. income tax as if the non-U.S. shareholder were a U.S. shareholder. A non-U.S. corporation receiving effectively connected dividends may also be subject to additional “branch profits tax” imposed at a rate of 30% (or lower treaty rate). A non-U.S. shareholder who fails to provide an IRS Form W-8BEN or other applicable form may be subject to back-up withholding at the appropriate rate.

In general, U.S. federal withholding tax will not apply to any gain or income realized by a non-U.S. shareholder in respect of any distributions of net long-term capital gains over net short-term capital losses, tax-exempt interest dividends, or upon the sale or other disposition of shares of a Fund. If a Fund’s direct or indirect interests in U.S. real property were to exceed certain levels, distributions to a non-U.S. shareholder from a Fund attributable to a REIT’s distribution to a Fund of gain from a sale or exchange of a U.S. real property interest and, in the case of a non-U.S. shareholder owning more than 5% of the class of shares throughout either such person’s holding period for the redeemed shares or, if shorter, the previous five years, the gain on redemption will be treated as real property gain subject to additional taxes or withholding and may result in the non-U.S. shareholder having additional filing requirements.

For taxable years beginning before January 1, 2012, distributions that a Fund reports as “short-term capital gain dividends” or “long-term capital gain dividends” are not treated as such to a recipient non-U.S. shareholder if the distribution is attributable to gain received from the sale or exchange of U.S. real property or an interest in a U.S. real property holding corporation and a Fund’s direct or indirect interests in U.S. real property exceed certain levels. Instead, if the non-U.S. shareholder has not owned more than 5% of the outstanding shares of a Fund at any time during the one year period ending on the date of distribution, such distribution is subject to 30% withholding by a Fund and is treated as ordinary dividends to the non-U.S. shareholder; if the non-U.S. shareholder owned more than 5% of the outstanding shares of a Fund at any time during the one year period ending on the date of the distribution, such distribution is treated as real property gain subject to 35% withholding tax and could subject the non-U.S. shareholder to U.S. filing requirements. Additionally, if a Fund’s direct or indirect interests in U.S. real property were to exceed certain levels, a non-U.S. shareholder realizing gains upon redemption from a Fund on or before December 31, 2011 could be subject to the 35% withholding tax and U.S. filing requirements unless more than 50% of a Fund’s shares were owned by U.S. persons at such time or unless the non-U.S. person had not held more than 5% of a Fund’s outstanding shares throughout either such person’s holding period for the redeemed shares or, if shorter, the previous five years.

The rules laid out in the previous two paragraphs, other than the withholding rules, will apply notwithstanding the Fund’s participation in a wash sale transaction or its payment of a substitute dividend.

Provided that 50% or more of the value of the Fund’s stock is held by U.S. shareholders, distributions of U.S. real property interests (including securities in a U.S. real property holding corporation, unless such corporation is regularly traded on an established securities market and the Fund has held 5% or less of the outstanding shares of the corporation during the five-year period ending on the date of distribution) occurring on or before December 31, 2011, in redemption of a foreign shareholder’s shares of the Fund will cause the Fund to recognize gain. If the Fund is required to recognize gain, the amount of gain recognized will be equal to the fair market value of such interests over the Fund’s adjusted bases to the extent of the greatest foreign ownership percentage of the Fund during the five-year period ending on the date of redemption.

For taxable years beginning before January 1, 2012, properly reported dividends are generally exempt from U.S. federal withholding tax where they (i) are paid in respect of a Fund’s “qualified net interest income” (generally, a Fund’s U.S. source interest income, other than certain contingent interest and interest from obligations of a corporation or partnership in which a Fund is at least a 10% shareholder, reduced by expenses that are allocable to such income), or (ii) are paid in respect of a Fund’s “qualified short-term capital gains” (generally, the excess of a Fund’s net short-term capital gain over a Fund’s long-term capital loss for such taxable year). However, depending on its circumstances, a Fund may report all, some or none of its potentially eligible dividends as such qualified net interest income or as qualified short-term capital gains and/or treat such dividends, in whole or in part, as ineligible for this exemption from withholding. In order to qualify for this exemption from withholding, a non-U.S. shareholder will need to comply with applicable certification requirements relating to its non-U.S. status (including, in general, furnishing an IRS Form W-8BEN or substitute Form). In the case of shares held through an intermediary, the intermediary may withhold even if a Fund reports the payment as qualified net interest income or qualified

short-term capital gain. Non-U.S. shareholders should contact their intermediaries with respect to the application of these rules to their accounts.

A 30% withholding tax will be imposed on dividends paid after December 31, 2013, and redemption proceeds paid after December 31, 2014, to (i) foreign financial institutions, including non-U.S. investment funds, unless they agree to collect and disclose to the IRS information regarding their direct and indirect U.S. account holders; and (ii) certain other foreign entities, unless they certify certain information regarding their direct and indirect U.S. owners. To avoid withholding, foreign financial institutions will need to enter into agreements with the IRS that state that they will provide the IRS information, including the name, address and taxpayer identification number of direct and indirect U.S. account holders; comply with due diligence procedures with respect to the identification of U.S. accounts; report to the IRS certain information with respect to U.S. accounts maintained; agree to withhold tax on certain payments made to non-compliant foreign financial institutions or to account holders who fail to provide the required information; and determine certain other information as to their account holders. Other foreign entities will need to provide the name, address, and taxpayer identification number of each substantial U.S. owner or certifications of no substantial U.S. ownership, unless certain exceptions apply.

Shares of a Fund held by a non-U.S. shareholder at death will be considered situated within the United States and subject to the U.S. estate tax for decedents dying after December 31, 2011, with a lookthrough rule applying before such date.

The foregoing discussion is a summary of certain material U.S. federal income tax considerations only and is not intended as a substitute for careful tax planning. Purchasers of shares should consult their own tax advisors as to the tax consequences of investing in such shares, including consequences under state, local and non-U.S. tax laws. Finally, the foregoing discussion is based on applicable provisions of the Internal Revenue Code, regulations, judicial authority and administrative interpretations in effect on the date of this SAI. Changes in applicable authority could materially affect the conclusions discussed above, and such changes often occur.

General Description of the Trust and the Fund

The Trust currently consists of more than 190 investment series or portfolios. The Trust was organized as a Delaware statutory trust on December 16, 1999 and is authorized to have multiple series or portfolios. The Trust is an open-end management investment company registered with the Securities and Exchange Commission (the “SEC”) under the Investment Company Act of 1940, as amended (the “1940 Act”). The offering of the Trust’s shares is registered under the Securities Act of 1933, as amended (the “1933 Act”). This SAI relates solely to the Fund.

The investment objective of the Fund is to seek investment results that correspond generally to the price and yield performance, before fees and expenses, of a specified benchmark index (the “Underlying Index”) representing publicly-traded equity securities of issuers in a particular broad market, market segment, market sector or group of industries. The Fund is managed by BlackRock Fund Advisors (“BFA”), a wholly-owned subsidiary of BTC, which in turn is indirectly wholly-owned by BlackRock, Inc.

The Fund offers and issues shares at their net asset value per share (“NAV”) only in aggregations of a specified number of shares (“Creation Unit”), generally in exchange for a designated portfolio of securities (including any portion of such securities for which cash may be substituted) included in its Underlying Index (the “Deposit Securities”), together with the deposit of a specified cash payment (the “Cash Component”). Shares of the Fund are listed for trading on The NASDAQ Stock Market (“NASDAQ” or the “Listing Exchange”), a national securities exchange. Shares trade in the secondary market and elsewhere at market prices that may be at, above or below NAV. Shares are redeemable only in Creation Units, and, generally, in exchange for portfolio securities and a Cash Component. Creation Units typically are a specified number of shares, generally 100,000 or multiples thereof.

The Trust reserves the right to permit or require that creations and redemptions of shares are effected fully or partially in cash. Shares may be issued in advance of receipt of Deposit Securities, subject to various conditions, including a requirement to maintain with the Trust a cash deposit equal to at least 105% and up to 115%, which percentage BFA may change from time to time, of the market value of the omitted Deposit Securities. See the Creation and Redemption of Creation Units section of this SAI. Transaction fees and other costs associated with creations or redemptions that include a cash portion may be higher than the transaction fees and other costs associated with in-kind creations or redemptions. In all cases, conditions and fees will be limited in accordance with the requirements of SEC rules and regulations applicable to management investment companies offering redeemable securities.

Exchange Listing and Trading

A discussion of exchange listing and trading matters associated with an investment in the Fund is contained in the Shareholder Information section of the Fund’s Prospectus. The discussion below supplements, and should be read in conjunction with, that section of the Prospectus.

Shares of the Fund are listed for trading, and trade throughout the day, on the Listing Exchange and other secondary markets. Shares of the Fund may also be listed on certain non-U.S. exchanges. There can be no assurance that the requirements of the Listing Exchange necessary to maintain the listing of shares of the Fund will continue to be met. The Listing Exchange may, but is not required to, remove the shares of the Fund from listing if (i) following the initial 12-month period beginning upon the commencement of trading of Fund shares, there are fewer than 50 beneficial owners of shares of the Fund for 30 or more consecutive trading days, (ii) the value of the Underlying Index on which the Fund is based is no longer calculated or available, (iii) the “indicative optimized portfolio value” (“IOPV”) of the Fund is no longer calculated or available, or (iv) any other event shall occur or condition shall exist that, in the opinion of the Listing Exchange, makes further dealings on the Listing Exchange inadvisable. The Listing Exchange will also remove shares of the Fund from listing and trading upon termination of the Fund.

As in the case of other publicly-traded securities, when you buy or sell shares through a broker you will incur a brokerage commission determined by that broker.

In order to provide additional information regarding the indicative value of shares of the Fund, the Listing Exchange or a market data vendor disseminates information every 15 seconds through the facilities of the Consolidated Tape Association, or through other widely disseminated means, an updated IOPV for the Fund as calculated by an information provider or market data vendor. The Trust is not involved in or responsible for any aspect of the calculation or dissemination of the IOPVs and makes no representation or warranty as to the accuracy of the IOPVs.

An IOPV has an equity securities component and a cash component. The equity securities values included in an IOPV are the values of the Deposit Securities for the Fund. While the IOPV reflects the current market value of the Deposit Securities required to be deposited in connection with the purchase of a Creation Unit, it does not necessarily reflect the precise composition of the current portfolio of securities held by the Fund at a particular point in time because the current portfolio of the Fund may include securities that are not a part of the current Deposit Securities. Therefore, the Fund’s IOPV disseminated during the Listing Exchange trading hours should not be viewed as a real-time update of the Fund’s NAV, which is calculated only once a day.

The cash component included in an IOPV consists of estimated accrued interest, dividends and other income, less expenses. If applicable, each IOPV also reflects changes in currency exchange rates between the U.S. dollar and the applicable currency.

The Trust reserves the right to adjust the share prices of the Fund in the future to maintain convenient trading ranges for investors. Any adjustments would be accomplished through stock splits or reverse stock splits, which would have no effect on the net assets of the Fund or an investor’s equity interest in the Fund.

Investment Strategies and Risks

The Fund seeks to achieve its objective by investing all its assets that are invested in Indian securities in a wholly-owned subsidiary located in the Republic of Mauritius (the “Subsidiary”). The remaining assets will be invested directly by the Fund. The Subsidiary and the Fund will collectively invest at least 90% of the Fund’s total assets in securities that comprise the Underlying Index and in depositary receipts representing securities of the Underlying Index. BFA will serve as investment adviser to both the Fund and the Subsidiary. Unless otherwise indicated, the term “Fund” as used in this SAI means the Fund and/or the Subsidiary, as applicable. The Fund operates as an index fund and will not be actively managed. Adverse performance of a security in the Fund’s portfolio will ordinarily not result in the elimination of the security from the Fund’s portfolio.

The Fund engages in representative sampling, which is investing in a sample of securities selected by BFA to have a collective investment profile similar to that of the Fund’s Underlying Index. Securities selected have aggregate investment characteristics (based on market capitalization and industry weightings), fundamental characteristics (such as return variability, earnings valuation and yield) and liquidity measures similar to those of the Underlying Index. Funds that use representative sampling generally do not hold all of the securities that are in the Underlying Index.

Currency Transactions. The Fund does not expect to engage in currency transactions for the purpose of hedging against declines in the value of the Fund’s assets that are denominated in a non-U.S. currency. The Fund may enter into non-U.S. currency forward and non-U.S. currency futures contracts to facilitate local securities settlements or to protect against currency exposure in connection with its distributions to shareholders, but may not enter into such contracts for speculative purposes.

A forward currency contract is an obligation to purchase or sell a specific currency at a future date, which may be any fixed number of days from the date of the contract agreed upon by the parties, at a price set at the time of the contract. A currency futures contract is a contract involving an obligation to deliver or acquire the specified amount of a specific currency, at a specified price and at a specified future time. Currency futures contracts may be settled on a net cash payment basis rather than by the sale and delivery of the underlying currency. To the extent required by law, liquid assets committed to futures contracts will be maintained.

Foreign exchange transactions involve a significant degree of risk and the markets in which foreign exchange transactions are effected are highly volatile, highly specialized and highly technical. Significant changes, including changes in liquidity and prices, can occur in such markets within very short periods of time, often within minutes. Foreign exchange trading risks include, but are not limited to, exchange rate risk, counterparty risk, maturity gap, interest rate risk, and potential interference

by foreign governments through regulation of local exchange markets, foreign investment or particular transactions in non-U.S. currency. If BFA utilizes foreign exchange transactions at an inappropriate time or judges market conditions, trends or correlations incorrectly, foreign exchange transactions may not serve their intended purpose of improving the correlation of the Fund’s return with the performance of the Underlying Index and may lower the Fund’s return. The Fund could experience losses if the value of its currency forwards, options and futures positions were poorly correlated with its other investments or if it could not close out its positions because of an illiquid market. In addition, the Fund could incur transaction costs, including trading commissions, in connection with certain non-U.S. currency transactions.

Diversification Status. The Fund is classified as “non-diversified.” A non-diversified fund is a fund that is not limited by the 1940 Act with regard to the percentage of its assets that may be invested in the securities of a single issuer. The securities of a particular issuer (or securities of issuers in particular industries) may dominate the underlying index of such a fund and, consequently, the fund’s investment portfolio. This may adversely affect the fund’s performance or subject the fund’s shares to greater price volatility than that experienced by more diversified investment companies.

The Fund intends to maintain the required level of diversification and otherwise conduct its operations so as to qualify as a Regulated Investment Company (“RIC”) for purposes of the U.S. Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”), and to relieve the Fund of any liability for U.S. federal income tax to the extent that its earnings are distributed to shareholders, provided that the Fund satisfies a minimum distribution requirement. Compliance with the diversification requirements of the Internal Revenue Code may limit the investment flexibility of the Fund and may make it less likely that the Fund will meet its investment objective.

Futures and Options. Futures contracts and options may be used by the Fund to simulate investment in its Underlying Index, to facilitate trading or to reduce transaction costs. The Fund may enter into futures contracts and options that are traded on a U.S. or non-U.S. exchange. The Fund will not use futures or options for speculative purposes. The Fund intends to use futures and options in accordance with Rule 4.5 of the Commodity Exchange Act (“CEA”). The Trust, on behalf of the Fund, has claimed an exclusion from the definition of the term “commodity pool operator” in accordance with Rule 4.5 so that the Fund is not subject to registration or regulation as a commodity pool operator under the CEA. On February 11, 2011, however, the Commodity Futures Trading Commission (“CFTC”) proposed certain regulatory changes that would subject registered investment companies to regulation by the CFTC if a fund invests more than a prescribed level of its liquidation value in futures and certain other instruments, or if the fund markets itself as providing investment exposure to such instruments. If these regulatory changes are ultimately adopted by the CFTC, the Fund may be subject to the CFTC registration requirements, and the disclosure and operations of the Fund would need to comply with all applicable regulations governing commodity pools. Compliance with these additional registration and regulatory requirements would increase Fund expenses. BFA may also be subject to CFTC regulation if the Fund is deemed to be a commodity pool. Other potentially adverse regulatory initiatives could also develop.

Futures contracts provide for the future sale by one party and purchase by another party of a specified amount of a specific instrument or index at a specified future time and at a specified price. Stock index contracts are based on investments that reflect the market value of common stock of the firms included in the investments. The Fund may enter into futures contracts to purchase securities indexes when BFA anticipates purchasing the underlying securities and believes prices will rise before the purchase will be made. To the extent required by law, liquid assets committed to futures contracts will be maintained.

A call option gives a holder the right to purchase a specific security at a specified price (“exercise price”) within a specified period of time. A put option gives a holder the right to sell a specific security at a specified exercise price within a specified period of time. The initial purchaser of a call option pays the “writer” a premium, which is paid at the time of purchase and is retained by the writer whether or not such option is exercised. The Fund may purchase put options to hedge its portfolio against the risk of a decline in the market value of securities held and may purchase call options to hedge against an increase in the price of securities it is committed to purchase. The Fund may write put and call options along with a long position in options to increase its ability to hedge against a change in the market value of the securities it holds or is committed to purchase. Investments in futures contracts and other investments that contain leverage may require the Fund to maintain liquid assets. Generally, the Fund maintains an amount of liquid assets equal to its obligations relative to the position involved, adjusted daily on a marked-to-market basis. With respect to futures contracts that are contractually required to “cash-settle,” the Fund maintains liquid assets in an amount at least equal to the Fund’s daily marked-to-market obligation (i.e., the Fund’s daily net liability, if any), rather than the contracts’ notional value (i.e., the value of the underlying asset). By maintaining assets equal to its net obligation under cash-settled futures contracts, the Fund may employ leverage to a

greater extent than if the Fund set aside assets equal to the futures contracts’ full notional value. The Fund bases its asset maintenance policies on methods permitted by the staff of the SEC and may modify these policies in the future to comply with any changes in the guidance articulated from time to time by the SEC or its staff.

Illiquid Securities. The Fund may invest up to an aggregate amount of 15% of its net assets in illiquid securities (calculated at the time of investment). Illiquid securities include securities subject to contractual or other restrictions on resale and other instruments that lack readily available markets.

Lending Portfolio Securities. The Fund may lend portfolio securities to certain creditworthy borrowers, including borrowers affiliated with BFA. The borrowers provide collateral that is maintained in an amount at least equal to the current market value of the securities loaned. No securities loan shall be made on behalf of the Fund if, as a result, the aggregate value of all securities loans of the Fund exceeds one-third of the value of the Fund’s total assets (including the value of the collateral received). The Fund may terminate a loan at any time and obtain the return of the securities loaned. The Fund receives the value of any interest or cash or non-cash distributions paid on the loaned securities.

With respect to loans that are collateralized by cash, the borrower will be entitled to receive a fee based on the amount of cash collateral. The Fund is compensated by the difference between the amount earned on the reinvestment of cash collateral and the fee paid to the borrower. In the case of collateral other than cash, the Fund is compensated by a fee paid by the borrower equal to a percentage of the market value of the loaned securities. Any cash collateral may be reinvested in certain short-term instruments either directly on behalf of the Fund or through one or more joint accounts or money market funds, including those affiliated with BFA; such reinvestments are subject to investment risk. BFA may receive compensation for these investments.

Securities lending involves exposure to certain risks, including operational risk (i.e., the risk of losses resulting from problems in the settlement and accounting process), “gap” risk (i.e., the risk of a mismatch between the return on cash collateral reinvestments and the fees the Fund has agreed to pay a borrower), and credit, legal, counterparty and market risk. If a securities lending counterparty were to default, the Fund would be subject to the risk of a possible delay in receiving collateral or in recovering the loaned securities, or to a possible loss of rights in the collateral. In the event a borrower does not return the Fund’s securities as agreed, the Fund may experience losses if the proceeds received from liquidating the collateral do not at least equal the value of the loaned security at the time the collateral is liquidated, plus the transaction costs incurred in purchasing replacement securities. This event could trigger adverse tax consequences for the Fund. Substitute payments for dividends received by the Fund for securities loaned out by the Fund will not be considered qualified dividend income. The Fund takes the tax effects of this difference into account in its securities lending program.

The Fund pays a portion of the interest or fees earned from securities lending to a borrower as described above and to a securities lending agent who administers the lending program in accordance with guidelines approved by the Trust’s Board of Trustees (the “Board” or the “Trustees”). To the extent that the Fund engages in securities lending, BTC acts as securities lending agent for the Fund, subject to the overall supervision of BFA. BTC receives a portion of the revenues generated by securities lending activities as compensation for its services.

Non-U.S. Securities. The Fund intends to purchase publicly-traded common stocks of non-U.S. issuers. To the extent the Fund invests in stocks of non-U.S. issuers, the Fund’s investment in such stocks may be in the form of American Depositary Receipts (“ADRs”), Global Depositary Receipts (“GDRs”) and European Depositary Receipts (“EDRs”) (collectively, “Depositary Receipts”). Depositary Receipts are receipts, typically issued by a bank or trust issuer, which evidence ownership of underlying securities issued by a non-U.S. issuer. For ADRs, the depository is typically a U.S. financial institution and the underlying securities are issued by a non-U.S. issuer. For other forms of Depositary Receipts, the depository may be a non-U.S. or a U.S. entity, and the underlying securities may be issued by a non-U.S. or a U.S. issuer. Depositary Receipts are not necessarily denominated in the same currency as their underlying securities. Generally, ADRs, issued in registered form, are designed for use in the U.S. securities markets, and EDRs, issued in bearer form, are designed for use in European securities markets. GDRs are tradable both in the United States and in Europe and are designed for use throughout the world.

The Fund will not invest in any unlisted Depositary Receipt or any Depositary Receipt that BFA deems illiquid at the time of purchase or for which pricing information is not readily available. In general, Depositary Receipts must be sponsored, but the Fund may invest in unsponsored Depositary Receipts under certain limited circumstances. The issuers of unsponsored Depositary Receipts are not obligated to disclose material information in the United States. Therefore, there may be less information available regarding such issuers and there may be no correlation between available information and the market value of the Depositary Receipts.

Investing in the securities of non-U.S. issuers involves special risks and considerations not typically associated with investing in U.S. issuers. These include differences in accounting, auditing and financial reporting standards, the possibility of expropriation or confiscatory taxation, adverse changes in investment or exchange control regulations, political instability which could affect U.S. investments in non-U.S. countries, and potential restrictions on the flow of international capital. Non-U.S. issuers may be subject to less governmental regulation than U.S. issuers. Moreover, individual non-U.S. economies may differ favorably or unfavorably from the U.S. economy in such respects as growth of gross domestic product, rate of inflation, capital reinvestment, resource self-sufficiency and balance of payment positions.

Options on Futures Contracts. An option on a futures contract, as contrasted with the direct investment in such a contract, gives the purchaser the right, in return for the premium paid, to assume a position in the underlying futures contract at a specified exercise price at any time prior to the expiration date of the option. Upon exercise of an option, the delivery of the futures position by the writer of the option to the holder of the option will be accompanied by delivery of the accumulated balance in the writer’s futures margin account that represents the amount by which the market price of the futures contract exceeds (in the case of a call) or is less than (in the case of a put) the exercise price of the option on the futures contract. The potential for loss related to the purchase of an option on a futures contract is limited to the premium paid for the option plus transaction costs. Because the value of the option is fixed at the point of sale, there are no daily cash payments by the purchaser to reflect changes in the value of the underlying contract; however, the value of the option changes daily and that change would be reflected in the NAV of the Fund. The potential for loss related to writing call options is unlimited. The potential for loss related to writing put options is limited to the agreed upon price per share, also known as the “strike price,” less the premium received from writing the put.

The Fund may purchase and write put and call options on futures contracts that are traded on an exchange as a hedge against changes in value of its portfolio securities, or in anticipation of the purchase of securities, and may enter into closing transactions with respect to such options to terminate existing positions. There is no guarantee that such closing transactions can be effected.

Upon entering into a futures contract, the Fund will be required to deposit with the broker an amount of cash or cash equivalents known as “initial margin,” which is in the nature of a performance bond or good faith deposit on the contract and is returned to the Fund upon termination of the futures contract, assuming all contractual obligations have been satisfied. Subsequent payments, known as “variation margin,” to and from the broker will be made daily as the price of the index underlying the futures contract fluctuates, making the long and short positions in the futures contract more or less valuable, a process known as “marking-to-market.” At any time prior to the expiration of a futures contract, the Fund may elect to close the position by taking an opposite position, which will operate to terminate the Fund’s existing position in the contract.

Repurchase Agreements. A repurchase agreement is an instrument under which the purchaser (i.e., the Fund) acquires the security and the seller agrees, at the time of the sale, to repurchase the security at a mutually agreed upon time and price, thereby determining the yield during the purchaser’s holding period. Repurchase agreements may be construed to be collateralized loans by the purchaser to the seller secured by the securities transferred to the purchaser. If a repurchase agreement is construed to be a collateralized loan, the underlying securities will not be considered to be owned by the Fund but only to constitute collateral for the seller’s obligation to pay the repurchase price, and, in the event of a default by the seller, the Fund may suffer time delays and incur costs or losses in connection with the disposition of the collateral.

In any repurchase transaction, the collateral for a repurchase agreement may include: (i) cash items; (ii) obligations issued by the U.S. government or its agencies or instrumentalities; or (iii) obligations that, at the time the repurchase agreement is entered into, are rated in the highest rating category generally by at least two nationally recognized statistical rating organizations (“NRSRO”), or, if unrated, determined to be of comparable quality by BFA. Collateral, however, is not limited to the foregoing and may include, for example, obligations rated below the highest category by NRSROs. Collateral for a repurchase agreement may also include securities that the Fund could not hold directly without the repurchase obligation. Irrespective of the type of collateral underlying the repurchase agreement, in the case of a repurchase agreement entered into by a non-money market fund, the repurchase obligation of a seller must be of comparable credit quality to securities which are rated in one of the two highest rating categories by any NRSRO.

Repurchase agreements pose certain risks for the Fund, should it decide to utilize them. Such risks are not unique to the Fund, but are inherent in repurchase agreements. The Fund seeks to minimize such risks, but because of the inherent legal uncertainties involved in repurchase agreements, such risks cannot be eliminated. Lower quality collateral and collateral with

longer maturities may be subject to greater price fluctuations than higher quality collateral and collateral with shorter maturities. If the repurchase agreement counterparty were to default, lower quality collateral may be more difficult to liquidate than higher quality collateral. Should the counterparty default and the amount of collateral not be sufficient to cover the counterparty’s repurchase obligation, the Fund would retain the status of an unsecured creditor of the counterparty (i.e., the position the Fund would normally be in if it were to hold, pursuant to its investment policies, other unsecured debt securities of the defaulting counterparty) with respect to the amount of the shortfall. As an unsecured creditor, the Fund would be at risk of losing some or all of the principal and income involved in the transaction.

Reverse Repurchase Agreements. Reverse repurchase agreements involve the sale of securities with an agreement to repurchase the securities at an agreed-upon price, date and interest payment and have the characteristics of borrowing. Generally, the effect of such transactions is that the Fund can recover all or most of the cash invested in the portfolio securities involved during the term of the reverse repurchase agreement, while in many cases the Fund is able to keep some of the interest income associated with those securities. Such transactions are advantageous only if the Fund has an opportunity to earn a rate of interest on the cash derived from these transactions that is greater than the interest cost of obtaining the same amount of cash. Opportunities to realize earnings from the use of the proceeds equal to or greater than the interest required to be paid may not always be available and the Fund intends to use the reverse repurchase technique only when BFA believes it will be advantageous to the Fund. The use of reverse repurchase agreements may exaggerate any interim increase or decrease in the value of the Fund’s assets. The Fund’s exposure to reverse repurchase agreements will be covered by liquid assets having a value equal to or greater than such commitments.

Securities of Investment Companies. The Fund may invest in the securities of other investment companies (including money market funds) to the extent allowed by law. Pursuant to the 1940 Act, the Fund’s investment in registered investment companies is limited to, subject to certain exceptions: (i) 3% of the total outstanding voting stock of any one investment company; (ii) 5% of the Fund’s total assets with respect to any one investment company; and (iii) 10% of the Fund’s total assets with respect to investment companies in the aggregate. To the extent allowed by law or regulation, the Fund may invest its assets in the securities of investment companies that are money market funds, including those advised by or otherwise affiliated with BFA, in excess of the limits discussed above. Other investment companies in which the Fund may invest can be expected to incur fees and expenses for operations, such as investment advisory and administration fees, which would be in addition to those incurred by the Fund.

Short-Term Instruments and Temporary Investments. The Fund may invest in short-term instruments, including money market instruments, on an ongoing basis to provide liquidity or for other reasons. Money market instruments are generally short-term investments that may include but are not limited to: (i) shares of money market funds (including those advised by BFA or otherwise affiliated with BFA); (ii) obligations issued or guaranteed by the U.S. government, its agencies or instrumentalities (including government-sponsored enterprises); (iii) negotiable certificates of deposit (“CDs”), bankers’ acceptances, fixed-time deposits and other obligations of U.S. and non-U.S. banks (including non-U.S. branches) and similar institutions; (iv) commercial paper rated, at the date of purchase, “Prime-1” by Moody’s® Investors Service, Inc., “F-1” by Fitch Inc., or “A-1” by Standard & Poor’s® (a subsidiary of The McGraw-Hill Companies, Inc.) (“S&P® ”), or if unrated, of comparable quality as determined by BFA; (v) non-convertible corporate debt securities (e.g., bonds and debentures) with remaining maturities at the date of purchase of not more than 397 days and that satisfy the rating requirements set forth in Rule 2a-7 under the 1940 Act; (vi) repurchase agreements; and (vii) short-term U.S. dollar-denominated obligations of non-U.S. banks (including U.S. branches) that, in the opinion of BFA, are of comparable quality to obligations of U.S. banks which may be purchased by the Fund. Any of these instruments may be purchased on a current or forward-settled basis. Time deposits are non-negotiable deposits maintained in banking institutions for specified periods of time at stated interest rates. Bankers’ acceptances are time drafts drawn on commercial banks by borrowers, usually in connection with international transactions.

Swap Agreements. Swap agreements are contracts between parties in which one party agrees to make periodic payments to the other party based on the change in market value or level of a specified rate, index or asset. In return, the other party agrees to make periodic payments to the first party based on the return of a different specified rate, index or asset. Swap agreements will usually be performed on a net basis, with the Fund receiving or paying only the net amount of the two payments. The net amount of the excess, if any, of the Fund’s obligations over its entitlements with respect to each swap is accrued on a daily basis and an amount of liquid assets having an aggregate value at least equal to the accrued excess will be maintained by the Fund.

The use of interest rate and index swaps is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio security transactions. These transactions generally do not involve the delivery of securities or other underlying assets or principal.

Tracking Stocks. A tracking stock is a separate class of common stock whose value is linked to a specific business unit or operating division within a larger company and is designed to “track” the performance of such business unit or division. The tracking stock may pay dividends to shareholders independent of the parent company. The parent company, rather than the business unit or division, generally is the issuer of tracking stock. However, holders of the tracking stock may not have the same rights as holders of the company’s common stock.

Future Developments. The Board may, in the future, authorize the Fund to invest in securities contracts and investments, other than those listed in this SAI and in the Prospectus, provided they are consistent with the Fund’s investment objective and do not violate any investment restrictions or policies.

General Considerations and Risks

A discussion of some of the principal risks associated with an investment in the Fund is contained in the Prospectus.

An investment in the Fund should be made with an understanding that the value of the Fund’s portfolio securities may fluctuate in accordance with changes in the financial condition of the issuers of the portfolio securities, the value of stocks in general, and other factors that affect the market.

Dividend Risk. There is no guarantee that the issuer of the stocks held by the Fund will declare dividends in the future or that if declared, they will either remain at current levels or increase over time.

Emerging Markets Risk. Investments in emerging markets are subject to a greater risk of loss than investments in developed markets. This is due to, among other things, greater market volatility, lower trading volume, political and economic instability, greater risk of a market shutdown and more governmental limitations on foreign investments than typically found in developed markets. Emerging markets may be more likely to experience inflation risk, political turmoil and rapid changes in economic conditions than more developed markets. Emerging markets often have less uniformity in accounting and reporting requirements, unreliable securities valuation and greater risk associated with custody of securities.

Risks of Derivatives. A derivative is a financial contract, the value of which depends on, or is derived from, the value of an underlying asset such as a security or an index. The Fund may invest in stock index futures contracts and other derivatives. Compared to conventional securities, derivatives can be more sensitive to changes in interest rates or to sudden fluctuations in market prices and thus the Fund’s losses may be greater if it invests in derivatives than if it invests only in conventional securities. Derivatives are also subject to counterparty risk, which is the risk that the other party in the transaction will not fulfill its contractual obligations.

Risks of Equity Securities. An investment in the Fund should be made with an understanding of the risks inherent in an investment in equity securities, including the risk that the financial condition of issuers may become impaired or that the general condition of stock markets may deteriorate (either of which may cause a decrease in the value of the portfolio securities and thus in the value of shares of the Fund). Common stocks are susceptible to general stock market fluctuations and to increases and decreases in value as market confidence and perceptions of their issuers change. These investor perceptions are based on various and unpredictable factors, including expectations regarding government, economic, monetary and fiscal policies, inflation and interest rates, economic expansion or contraction, and global or regional political, economic or banking crises. Holders of common stocks incur more risks than holders of preferred stocks and debt obligations because common stockholders generally have rights to receive payments from stock issuers that are inferior to the rights of creditors, or holders of debt obligations or preferred stocks. Further, unlike debt securities, which typically have a stated principal amount payable at maturity (the value of which, however, is subject to market fluctuations prior to maturity), or preferred stocks, which typically have a liquidation preference and which may have stated optional or mandatory redemption provisions, common stocks have neither a fixed principal amount nor a maturity.

Although most of the securities in the Underlying Index are listed on a national securities exchange, the principal trading market for some of the securities may be in the over-the-counter market. The existence of a liquid trading market for certain securities may depend on whether dealers will make a market in such securities. There can be no assurance that a market

will be made or maintained or that any such market will be or remain liquid. The price at which securities may be sold and the value of the Fund’s shares will be adversely affected if trading markets for the Fund’s portfolio securities are limited or absent, or if bid/ask spreads are wide.

Risks of Futures and Options Transactions. There are several risks accompanying the utilization of futures contracts and options on futures contracts. First, a position in futures contracts and options on futures contracts may be closed only on the exchange on which the contract was made (or a linked exchange). While the Fund plans to utilize futures contracts only if an active market exists for such contracts, there is no guarantee that a liquid market will exist for the contract at a specified time. Furthermore, because, by definition, futures contracts project price levels in the future and not current levels of valuation, market circumstances may result in a discrepancy between the price of the stock index future and the movement in the Fund’s Underlying Index. In the event of adverse price movements, the Fund would continue to be required to make daily cash payments to maintain its required margin. In such situations, if the Fund has insufficient cash, it may have to sell portfolio securities to meet daily margin requirements at a time when it may be disadvantageous to do so. In addition, the Fund may be required to deliver the instruments underlying the future contracts it has sold.

The risk of loss in trading futures contracts or uncovered call options in some strategies (e.g., selling uncovered stock index futures contracts) is potentially unlimited. The Fund does not plan to use futures and options contracts in this way. The risk of a futures position may still be large as traditionally measured due to the low margin deposits required. In many cases, a relatively small price movement in a futures contract may result in immediate and substantial loss or gain to the investor relative to the size of a required margin deposit. The Fund, however, intends to utilize futures and options contracts in a manner designed to limit the risk exposure to levels comparable to a direct investment in the types of stocks in which it invests.

Utilization of futures and options on futures by the Fund involves the risk of imperfect or even negative correlation to the Underlying Index if the index underlying the futures contract differs from the Underlying Index. There is also the risk of loss by the Fund of margin deposits in the event of bankruptcy of a broker with whom the Fund has an open position in the futures contract or option. The purchase of put or call options will be based upon predictions by BFA as to anticipated trends, which predictions could prove to be incorrect.

Because the futures market generally imposes less burdensome margin requirements than the securities market, an increased amount of participation by speculators in the futures market could result in price fluctuations. Certain financial futures exchanges limit the amount of fluctuation permitted in futures contract prices during a single trading day. The daily limit establishes the maximum amount by which the price of a futures contract may vary either up or down from the previous day’s settlement price at the end of a trading session. Once the daily limit has been reached in a particular type of contract, no trades may be made on that day at a price beyond that limit. It is possible that futures contract prices could move to the daily limit for several consecutive trading days with little or no trading, thereby preventing prompt liquidation of futures positions and subjecting the Fund to substantial losses. In the event of adverse price movements, the Fund would be required to make daily cash payments of variation margin.

Risks of Investing in Asia. Investments in securities of issuers in certain Asian countries involve risks not typically associated with investments in securities of issuers in more developed countries. Such heightened risks include, among others, expropriation and/or nationalization of assets, confiscatory taxation, political instability, including authoritarian and/or military involvement in governmental decision-making, armed conflict and social instability as a result of religious, ethnic and/or socio-economic unrest.

Certain Asian countries have democracies with relatively short histories, which may increase the risk of political instability. These countries have faced political and military unrest, and further unrest could present a risk to their local economies and securities markets. Indonesia and the Philippines have each experienced violence and terrorism, which has negatively impacted their economies. North and South Korea each have substantial military capabilities, and historical tensions between the two countries present the risk of war. Any outbreak of hostilities between the two countries could have a severe adverse effect on the South Korean economy and securities market. Increased political and social unrest in these geographic areas could adversely affect the performance of investments in this region.

Certain governments in this region administer prices on several basic goods, including fuel and electricity, within their respective countries. Certain governments may exercise substantial influence over many aspects of the private sector in their respective countries and may own or control many companies. Future government actions could have a significant effect on

the economic conditions in this region, which in turn could have a negative impact on private sector companies. There is also the possibility of diplomatic developments adversely affecting investments in the region.

Corruption and the perceived lack of a rule of law in dealings with international companies in certain Asian countries may discourage foreign investment and could negatively impact the long-term growth of certain economies in this region. In addition, certain countries in the region are experiencing high unemployment and corruption, and have fragile banking sectors.

Some economies in this region are dependent on a range of commodities, including oil, natural gas and coal. Accordingly, they are strongly affected by international commodity prices and particularly vulnerable to any weakening in global demand for these products. The market for securities in this region may also be directly influenced by the flow of international capital, and by the economic and market conditions of neighboring countries. Adverse economic conditions or developments in neighboring countries may increase investors’ perception of the risk of investing in the region as a whole, which may adversely impact the market value of the securities issued by companies in the region.

Risks of Investing in China. Investments in securities of companies domiciled in China involves a high degree of risk and special considerations not typically associated with investing in the U.S. securities markets. Such heightened risks include, among others, an authoritarian government, popular unrest associated with demands for improved political, economic and social conditions, the impact of regional conflict on the economy and hostile relations with neighboring countries.

Military conflicts, either in response to internal social unrest or conflicts with other countries, could disrupt economic development. The Chinese economy is vulnerable to the long-running disagreements with Hong Kong related to integration and religious and nationalist disputes with Tibet. China has a complex territorial dispute regarding the sovereignty of Taiwan that has included threats of invasion; Taiwan-based companies and individuals are significant investors in China. Military conflict between China and Taiwan may adversely affect securities of Chinese issuers. In addition, China has strained international relations with Japan, India, Russia and other neighbors due to territorial disputes, historical animosities and other defense concerns. China could be affected by military events on the Korean peninsula or internal instability within North Korea. These situations may cause uncertainty in the Chinese market and may adversely affect performance of the Chinese economy.

The Chinese government has implemented significant economic reforms in order to liberalize trade policy, promote foreign investment in the economy, reduce government control of the economy and develop market mechanisms. But there can be no assurance that these reforms will continue or that they will be effective. Despite recent reform and privatizations of companies in certain sectors, the Chinese government still exercises substantial influence over many aspects of the private sector and may own or control many companies. The Chinese government continues to maintain a major role in economic policy making and investing in China involves risk of loss due to expropriation, nationalization, confiscation of assets and property or the imposition of restrictions on foreign investments and on repatriation of capital invested. In addition, there is less regulation and monitoring of Chinese securities markets and the activities of investors, brokers and other participants than in the United States. Accordingly, issuers of securities in China are not subject to the same degree of regulation as are U.S. issuers with respect to such matters as insider trading rules, tender offer regulation, stockholder proxy requirements and the requirements mandating timely and accurate disclosure of information. Stock markets in China are in the process of change and further development. This may lead to trading volatility, difficulty in the settlement and recording of transactions and difficulty in interpreting and applying the relevant regulation.

While the Chinese economy has grown rapidly in recent years, there is no assurance that this growth rate will be maintained. China may experience substantial rates of inflation or economic recessions, causing a negative effect on the economy and securities market. China’s economy is heavily dependent on export growth. Reduction in spending on Chinese products and services, institution of tariffs or other trade barriers or a downturn in any of the economies of China’s key trading partners may have an adverse impact on the securities of Chinese issuers.

The tax laws and regulations in the People’s Republic of China (“PRC”) are subject to change, including the issuance of authoritative guidance or enforcement, possibly with retroactive effect. The interpretation, applicability and enforcement of such laws by PRC tax authorities are not as consistent and transparent as those of more developed nations, and may vary over time and from region to region. The application and enforcement of PRC tax rules could have a significant adverse effect on the Fund and its investors, particularly in relation to capital gains withholding tax imposed upon non-residents.

Risks of Investing in Emerging Markets Securities. Investments in emerging market countries may be subject to greater risks than investments in developed countries. These risks include: (i) less social, political, and economic stability; (ii) greater illiquidity and price volatility due to smaller or limited local capital markets for such securities, or low non-existent trading volumes; (iii) foreign exchanges and broker-dealers may be subject to less scrutiny and regulation by local authorities; (iv) local governments may decide to seize or confiscate securities held by foreign investors and/or local governments may decide to suspend or limit an issuer’s ability to make dividend or interest payments; (v) local governments may limit or entirely restrict repatriation of invested capital, profits, and dividends; (vi) capital gains may be subject to local taxation, including on a retroactive basis; (vii) issuers facing restrictions on dollar or euro payments imposed by local governments may attempt to make dividend or interest payments to foreign investors in the local currency; (viii) investors may experience difficulty in enforcing legal claims related to the securities and/or local judges may favor the interests of the issuer over those of foreign investors; (ix) bankruptcy judgments may only be permitted to be paid in the local currency; (x) limited public information regarding the issuer may result in greater difficulty in determining market valuations of the securities, and (xi) lax financial reporting on a regular basis, substandard disclosure and differences in accounting standards may make it difficult to ascertain the financial health of an issuer.

Emerging market securities markets are typically marked by a high concentration of market capitalization and trading volume in a small number of issuers representing a limited number of industries, as well as a high concentration of ownership of such securities by a limited number of investors. In addition, brokerage and other costs associated with transactions in emerging markets securities markets can be higher, sometimes significantly, than similar costs incurred in securities markets in developed countries. Although some emerging markets have become more established and tend to issue securities of higher credit quality, the markets for securities in other emerging countries are in the earliest stages of their development, and these countries issue securities across the credit spectrum. Even the markets for relatively widely traded securities in emerging countries may not be able to absorb, without price disruptions, a significant increase in trading volume or trades of a size customarily undertaken by institutional investors in the securities markets of developed countries. The limited size of many of these securities markets can cause prices to be erratic for reasons apart from factors that affect the soundness and competitiveness of the securities issuers. For example, prices may be unduly influenced by traders who control large positions in these markets. Additionally, market making and arbitrage activities are generally less extensive in such markets, which may contribute to increased volatility and reduced liquidity of such markets. The limited liquidity of emerging country securities may also affect the Fund’s ability to accurately value its portfolio securities or to acquire or dispose of securities at the price and time it wishes to do so or in order to meet redemption requests.

Many emerging market countries suffer from uncertainty and corruption in their legal frameworks. Legislation may be difficult to interpret and laws may be too new to provide any precedential value. Laws regarding foreign investment and private property may be weak or non-existent. Sudden changes in governments may result in policies which are less favorable to investors such as policies designed to expropriate or nationalize “sovereign” assets. Certain emerging market countries in the past have expropriated large amounts of private property, in many cases with little or no compensation, and there can be no assurance that such expropriation will not occur in the future.

Foreign investment in the securities markets of certain emerging countries is restricted or controlled to varying degrees. These restrictions may limit the Fund’s investment in certain emerging countries and may increase the expenses of the Fund. Certain emerging countries require governmental approval prior to investments by foreign persons or limit investment by foreign persons to only a specified percentage of an issuer’s outstanding securities or a specific class of securities which may have less advantageous terms (including price) than securities of the company available for purchase by nationals.

Many emerging market countries lack the social, political, and economic stability characteristic of the United States. Political instability among emerging market countries can be common and may be caused by an uneven distribution of wealth, social unrest, labor strikes, civil wars, and religious oppression. Economic instability in emerging market countries may take the form of: (i) high interest rates; (ii) high levels of inflation, including hyperinflation; (iii) high levels of unemployment or underemployment; (iv) changes in government economic and tax policies, including confiscatory taxation; and (v) imposition of trade barriers.

The Fund’s income and, in some cases, capital gains from foreign securities will be subject to applicable taxation in certain of the emerging market countries in which it invests, and treaties between the United States and such countries may not be available in some cases to reduce the otherwise applicable tax rates.

Emerging markets also have different clearance and settlement procedures, and in certain of these emerging markets there have been times when settlements have been unable to keep pace with the volume of securities transactions, making it difficult to conduct such transactions.

In the past, governments within the emerging markets have become overly reliant on the international capital markets and other forms of foreign credit to finance large public spending programs, which in the past have caused huge budget deficits. Often, interest payments have become too overwhelming for a government to meet, representing a large percentage of total gross domestic product (“GDP”). These foreign obligations have become the subject of political debate and served as fuel for political parties of the opposition, which pressure the government not to make payments to foreign creditors, but instead to use these funds for, among other things, social programs. Either due to an inability to pay or submission to political pressure, foreign governments have been forced to seek a restructuring of their loan and/or bond obligations, have declared a temporary suspension of interest payments or have defaulted. These events have adversely affected the values of securities issued by foreign governments and corporations domiciled in those countries and have negatively affected not only their cost of borrowing, but their ability to borrow in the future as well.

Risks of Investing in India. India is an emerging market and demonstrates significantly higher volatility from time to time in comparison to more developed markets. Political, religious, and border disputes persist in India. India has recently experienced and may continue to experience civil unrest and hostilities with certain of its neighboring countries, including Pakistan, and the Indian government has confronted separatist movements in several Indian states, including Kashmir. Government control over the economy, currency fluctuations or blockage, and the risk of nationalization or expropriation of assets may offer higher potential for losses. Governmental actions could have a negative effect on the economic conditions in India, which could adversely affect the value and liquidity of investments made by the Fund. The securities markets in India are comparatively underdeveloped and with some exceptions, consist of a small number of listed companies with small market capitalization, greater price volatility and substantially less liquidity than companies in more developed markets. Stockbrokers and other intermediaries in India may not perform as well as their counterparts in the United States or other, more developed countries. The limited liquidity of the Indian securities markets may also affect the Fund’s ability to acquire or dispose of securities at the price or time that it desires or the Fund’s ability to track the Underlying Index.

Global factors and foreign actions may inhibit the flow of foreign capital on which India is dependent to sustain its growth. In addition, the Reserve Bank of India has imposed limits on foreign ownership of Indian companies, which may decrease the liquidity of the Fund’s portfolio and result in extreme volatility in the prices of Indian securities. These factors, coupled with the lack of extensive accounting, auditing and financial reporting standards and practices, as applicable in the United States, may increase the risk of loss for the Fund.

Securities laws in India are relatively new and unsettled and, as a result, there is a risk of significant and unpredictable change in laws governing foreign investment, securities regulation, title to securities and shareholder rights. Foreign investors in particular may be adversely affected by new or amended laws and regulations. Certain Indian regulatory approvals, including approvals from the Securities and Exchange Board of India, the central government and the tax authorities (to the extent that tax benefits need to be utilized), may be required before the Fund can make investments in Indian companies.

Technology and software sectors represent a significant portion of the total capitalization of the Indian securities markets. The value of these companies will generally fluctuate in response to technological and regulatory developments, and, as a result, the Fund’s holdings are expected to experience correlated fluctuations.

Natural disasters, such as tsunamis, flooding or droughts, could occur in India, Mauritius or surrounding areas and could negatively affect the Indian economy or operations of the Subsidiary, and, in turn, could negatively affect the Fund.

Risks of Investing in Non-U.S. Equity Securities. An investment in the Fund involves risks similar to those of investing in portfolios of equity securities traded on non-U.S. exchanges. These risks include market fluctuations caused by such factors as economic and political developments, changes in interest rates and perceived trends in stock prices. Investing in securities issued by issuers domiciled in countries other than the domicile of the investor and denominated in currencies other than an investor’s local currency entails certain considerations and risks not typically encountered by the investor in making investments in its home country and in that country’s currency. These considerations include favorable or unfavorable changes in interest rates, currency exchange rates, exchange control regulations and the costs that may be incurred in connection with conversions between various currencies. Investing in the Fund also involves certain risks and considerations not typically associated with investing in a fund whose portfolio contains exclusively securities of U.S. issuers. These risks include generally less liquid and less efficient securities markets; generally greater price volatility; less publicly available

information about issuers; the imposition of withholding or other taxes; the imposition of restrictions on the expatriation of funds or other assets of the Fund; higher transaction and custody costs; delays and risks attendant in settlement procedures; difficulties in enforcing contractual obligations; lower liquidity and significantly smaller market capitalization; different accounting and disclosure standards; lower levels of regulation of the securities markets; more substantial government interference with the economy; higher rates of inflation; greater social, economic, and political uncertainty; the risk of nationalization or expropriation of assets; and the risk of war.

Risks of Investing in South Korea. Investments in South Korean issuers involve risks that are specific to South Korea, including legal, regulatory, political, currency, security and economic risks. Substantial political tensions exist between North Korea and South Korea and recently, these political tensions have escalated. The outbreak of hostilities between the two nations, or even the threat of an outbreak of hostilities will likely adversely impact the South Korean economy. In addition, South Korea’s economic growth potential has recently been on a decline, mainly because of a rapidly aging population and structural problems.

Risks of Investing in the Consumer Discretionary Sector. Companies engaged in the design, production or distribution of products or services for the consumer discretionary sector (including, without limitation, television and radio broadcasting, manufacturing, publishing, recording and musical instruments, motion pictures, photography, amusement and theme parks, gaming casinos, sporting goods and sports arenas, camping and recreational equipment, toys and games, apparel, travel-related services, automobiles, hotels and motels, and fast food and other restaurants) are subject to the risk that their products or services may become obsolete quickly. The consumer discretionary sector can be significantly affected by several factors, including, without limitation, the performance of domestic and international economies, exchange rates, changing consumer tastes and trends, marketing campaigns, cyclical revenue generation, consumer confidence, commodity price volatility, labor relations, interest rates, import and export controls, intense competition, technological developments and government regulation.

Risks of Investing in the Consumer Staples Sector. Companies in the consumer staples sector may be adversely affected by changes in the global economy, consumer spending, competition, demographics and consumer preferences, and production spending. Companies in the consumers staples sector are also affected by changes in government regulation, global economic, environmental and political events, economic conditions and the depletion of resources. In addition, companies in the consumers staples sector may be subject to risks pertaining to the supply of, demand for and prices of raw materials. The prices of raw materials fluctuate in response to a number of factors, including, without limitation, changes in government agricultural support programs, exchange rates, import and export controls, changes in international agricultural and trading policies, and seasonal and weather conditions.

Risks of Investing in the Energy Sector. Companies in the energy sector are strongly affected by the levels and volatility of global energy prices, energy supply and demand, government regulations and policies, energy production and conservation, efforts and technological change. Prices and supplies of energy may fluctuate significantly over short and long periods of time due to national and international political changes, Organization of Petroleum Exporting Countries (“OPEC”) policies, changes in relationships among OPEC members and between OPEC and oil-importing nations, the regulatory environment, taxation policies, and the economy of the key energy-consuming countries. In addition, companies in the energy sector are at risk of civil liability from accidents resulting in injury, loss of life or property, pollution or other environmental damage claims and risk of loss from terrorism and natural disasters. Disruptions in the oil industry or shifts in fuel consumption may significantly impact companies in this sector. In addition, because a significant portion of revenues of companies in this sector are derived from a relatively small number of customers that are largely composed of governmental entities and utilities, governmental budget constraints may have a significant impact on the stock prices of companies in this industry.

Risks of Investing in the Financial Sector. Companies in the financial sector include regional and money center banks, securities brokerage firms, asset management companies, savings banks and thrift institutions, specialty finance companies (e.g., credit card, mortgage providers), insurance and insurance brokerage firms, financial conglomerates and foreign banking and financial companies. The global financial markets have recently experienced very difficult conditions and volatility as well as significant adverse trends. The deteriorating conditions in these markets have resulted in a decrease in availability of corporate credit, capital and liquidity and have led indirectly to the insolvency, closure or acquisition of a number of financial institutions. These conditions have also contributed to consolidation within the financial industry. In addition, the global financial industry has been materially and adversely affected by a significant decline in the value of mortgage-backed and asset-backed securities, and by the sovereign debt crisis. The prospects of many financial companies are questionable and continue to evolve as financial companies revise their outlooks and write down assets that they hold.

Most financial companies are subject to extensive governmental regulation, which limits their activities and may affect their ability to earn a profit from a given line of business. Government regulation may change frequently and may have significant adverse consequences for companies in the financial sector, including effects not intended by the regulation. Direct governmental intervention in the operations of financial companies and financial markets may materially and adversely affect the companies in which the Fund invests, including recent legislation in many countries that may increase government regulation, repatriation and other intervention. The impact of governmental intervention and recent legislation on any individual financial company or on the financial sector as a whole cannot be predicted. The valuation of financial companies has been and continues to be subject to unprecedented volatility and may be influenced by unpredictable factors, including interest rate risk and sovereign debt default. Certain financial businesses are subject to intense competitive pressures, including market share and price competition. Financial companies in foreign countries are subject to market specific and general regulatory and interest rate concerns. In particular, government regulation in certain foreign countries may include taxes and controls on interest rates, credit availability, minimum capital requirements, ban on short sales, prices and currency transfers.

The profitability of banks, savings and loan associations and financial companies is largely dependent on the availability and cost of capital funds and can fluctuate significantly when interest rates change. In addition, general economic conditions are important to the operations of these concerns, with exposure to credit losses resulting from financial difficulties of borrowers having an adverse effect on the profitability of financial companies. Financial companies can be highly dependent upon access to capital markets and any impediments to such access, such as adverse overall economic conditions or a negative perception in the capital markets of a financial company’s financial condition or prospects, could adversely affect its business.

Risks of Investing in the Industrials Sector. The stock prices of companies in the industrials sector are affected by supply and demand both for their specific product or service and for industrials sector products in general. The products of manufacturing companies may face product obsolescence due to rapid technological developments and frequent new product introduction. Government regulations, world events and economic conditions affect the performance of companies in the industrials sector. Companies in the industrials sector may be adversely affected by liability for environmental damage, product liability claims and exchange rates. The industrials sector may also be adversely affected by changes or trends in commodity prices, which may be influenced by unpredictable factors.

Risks of Investing in the Information Technology Sector. Information technology companies face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Like other technology companies, information technology companies may have limited product lines, markets, financial resources or personnel. The products of information technology companies may face product obsolescence due to rapid technological developments and frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Companies in the information technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies.

Risks of Investing in the Materials Sector. Companies in the materials sector could be adversely affected by commodity price volatility, exchange rates, import controls, increased competition, depletion of resources, technical progress, labor relations, exchange rates and government regulations, among other factors. Also, companies in the materials sector are at risk of liability for environmental damage and product liability claims. Production of materials may exceed demand as a result of market imbalances or economic downturns, leading to poor investment returns.

Risks of Investing in the Telecommunications Sector. The telecommunications sector of an economy is often subject to extensive government regulation. The costs of complying with governmental regulations, delays or failure to receive required regulatory approvals or the enactment of new adverse regulatory requirements may adversely affect the business of the telecommunications companies. Government actions around the world, specifically in the area of pre-marketing clearance of products and prices, can be arbitrary and unpredictable. Companies in the telecommunications sector may encounter distressed cash flows due to the need to commit substantial capital to meet increasing competition, particularly in formulating new products and services using new technology. Technological innovations may make the products and services of telecommunications companies obsolete.

Risks of Investing in the Utilities Sector. Investments in utility companies involve special considerations, including the risk of changing commodity prices, government regulation stipulating rates charged by utilities, increased tariffs, changes in tax laws, interest rate fluctuations and changes in the cost of providing the specific utility services. The utilities industry is also

subject to potential terrorist attacks, natural disasters and severe weather conditions, as well as regulatory and operational burdens associated with the operation and maintenance of nuclear facilities. Government regulators monitor and control utility revenues and costs, and therefore may limit utility profits. In certain countries regulatory authorities may also restrict a company’s access to new markets, thereby diminishing a company’s long-term prospects. The deregulation of certain utilities companies may eliminate restrictions on profits but may also subject these companies to greater risks of loss.

Risks of Swap Agreements. The risk of loss with respect to swaps generally is limited to the net amount of payments that the Fund is contractually obligated to make. Swap agreements are subject to the risk that the swap counterparty will default on its obligations. If such a default occurs, the Fund will have contractual remedies pursuant to the agreements related to the transaction. However, such remedies may be subject to bankruptcy and insolvency laws which could affect the Fund’s rights as a creditor (e.g., the Fund may not receive the net amount of payments that it is contractually entitled to receive).

Tax Risk. The Fund, through the Subsidiary, will seek to obtain benefits from favorable tax treatment by the Indian government pursuant to the treaty between India and the Republic of Mauritius (the “DTAA”). The Supreme Court of India has upheld the validity of the DTAA in response to a challenge in a lower court contesting the DTAA’s applicability to entities such as the Fund or the Subsidiary; however, there can be no assurance that any future challenge will result in a favorable outcome. Additionally, in a number of recent cases, the Indian tax authorities have taken positions that have led to uncertainties in relation to the availability of DTAA benefits. Recently, there have been reports in the Indian press that the DTAA may be re-negotiated. There can be no assurance that the terms of the DTAA will not be subject to re-negotiation in the future or subject to a different interpretation or that the Subsidiary will continue to be deemed a tax resident by the Republic of Mauritius, allowing it favorable tax treatment. Any change in the provisions of this DTAA or in its applicability to the Subsidiary could result in the imposition of withholding and other taxes on the Subsidiary by India, which would reduce the return to theFund on its investments.

The Direct Taxes Code, 2010 (the “New Taxes Code”) was recently tabled before the Lok Sabha (the lower house of the Indian Parliament), which, if enacted, will replace the existing Income Tax Act, 1961 (“ITA”) with effect from April 1, 2012. Further, provisions of the New Taxes Code, if enacted, could change the manner in which the Subsidiary is currently taxed in India, and could adversely impact the returns to the Fund/Subsidiary and its shareholders. In addition, the New Taxes Code may not be enacted in its current draft form. Hence, no assurance can be given that the interpretations described in this discussion will remain in effect. Any changes could also be applied retroactively, including to transactions entered into before the effective date of the New Taxes Code. Investors are urged to consult their own tax advisors with respect to their own tax situations and the tax consequences of an investment in the Fund. For a brief overview of matters in relation to Indian taxation, please see The Direct Taxes Code, 2010 section of this SAI.

Proxy Voting Policy

The Trust has adopted, as its proxy voting policies for the Fund, the proxy voting guidelines of BFA, the investment adviser to the Fund. The Trust has delegated to BFA the responsibility for voting proxies on the portfolio securities held by the Fund. The remainder of this section discusses the Fund’s proxy voting guidelines and BFA’s role in implementing such guidelines.

BFA votes (or refrains from voting) proxies for the Fund in a manner that BFA, in the exercise of its independent business judgment, concludes is in the best economic interests of the Fund. In some cases, BFA may determine that it is in the best economic interests of the Fund to refrain from exercising the Fund’s proxy voting rights (such as, for example, proxies on certain non-U.S. securities that might impose costly or time-consuming in-person voting requirements). With regard to the relationship between securities lending and proxy voting, BFA’s approach is also driven by the Fund’s economic interests. The evaluation of the economic desirability of recalling loans involves balancing the revenue-producing value of loans against the likely economic value of casting votes. Based on our evaluation of this relationship, we believe that the likely economic value of casting a vote generally is less than the securities lending income, either because the votes will not have significant economic consequences or because the outcome of the vote would not be affected by BFA recalling loaned securities in order to ensure they are voted. Periodically, BFA analyzes the process and benefits of voting proxies for securities on loan, and will consider whether any modification of its proxy voting policies or procedures are necessary in light of any regulatory changes. BFA will normally vote on specific proxy issues in accordance with its proxy voting guidelines. BFA’s proxy voting guidelines provide detailed guidance as to how to vote proxies on certain important or commonly raised issues. BFA may, in the exercise of its business judgment, conclude that the proxy voting guidelines do not cover the specific matter upon which a proxy vote is requested, or that an exception to the proxy voting guidelines would be in the best economic interests of the

Fund. BFA votes (or refrains from voting) proxies without regard to the relationship of the issuer of the proxy (or any shareholder of such issuer) to the Fund, the Fund’s affiliates (if any), BFA or BFA’s affiliates, or the Distributor or the Distributor’s affiliates. When voting proxies, BFA attempts to encourage issuers to follow practices that enhance shareholder value and increase transparency and allow the market to place a proper value on their assets. With respect to certain specific issues:

  • The Fund generally supports the board’s nominees in the election of directors and generally supports proposals that strengthen the independence of boards of directors;
  • The Fund generally does not support proposals on social issues that lack a demonstrable economic benefit to the issuer and the Fund investing in such issuer; and
  • The Fund generally votes against anti-takeover proposals and proposals that would create additional barriers or costs to corporate transactions that are likely to deliver a premium to shareholders.

BFA maintains institutional policies and procedures that are designed to prevent any relationship between the issuer of the proxy (or any shareholder of the issuer) and the Fund, the Fund’s affiliates (if any), BFA or BFA’s affiliates (if any) or the Distributor or the Distributor’s affiliates, from having undue influence on BFA’s proxy voting activity. In certain instances, BFA may determine to engage an independent fiduciary to vote proxies as a further safeguard against potential conflicts of interest or as otherwise required by applicable law. The independent fiduciary may either vote such proxies or provide BFA with instructions as to how to vote such proxies. In the latter case, BFA votes the proxy in accordance with the independent fiduciary’s determination.

Information with respect to how BFA voted proxies relating to the Fund’s portfolio securities during the 12-month period ended June 30 will be available: (i) without charge, upon request, by calling 1-800-iShares (1-800-474-2737) or through the Fund’s website at www.iShares.com; and (ii) on the SEC’s website at www.sec.gov.

Portfolio Holdings Information

The Board has adopted a policy regarding the disclosure of the Fund’s portfolio holdings information that requires that such information be disclosed in a manner that: (i) is consistent with applicable legal requirements and in the best interests of the Fund’s shareholders; (ii) does not put the interests of BFA, the Distributor or any affiliated person of BFA or the Distributor, above those of Fund shareholders; (iii) does not advantage any current or prospective Fund shareholders over any other current or prospective Fund shareholders, except to the extent that certain Entities (as described below) may receive portfolio holdings information not available to other current or prospective Fund shareholders in connection with the dissemination of information necessary for transactions in Creation Units, as contemplated by the iShares Exemptive Orders and as discussed below; and (iv) does not provide selective access to portfolio holdings information except pursuant to the procedures outlined below and to the extent appropriate confidentiality arrangements limiting the use of such information are in effect. The “Entities” referred to in sub-section (iii) above are generally limited to National Securities Clearing Corporation (“NSCC”) members, subscribers to various fee-based subscription services, large institutional investors (known as “Authorized Participants”) that have been authorized by the Distributor to purchase and redeem large blocks of shares pursuant to legal requirements, including exemptive orders granted by the SEC pursuant to which the Fund offers and redeems its shares (“iShares Exemptive Orders”) and other institutional market participants and entities that provide information services.

Each business day, the Fund’s portfolio holdings information will be provided to the Distributor or other agent for dissemination through the facilities of the NSCC and/or other fee-based subscription services to NSCC members and/or subscribers to those other fee-based subscription services, including Authorized Participants, and to entities that publish and/or analyze such information in connection with the process of purchasing or redeeming Creation Units or trading shares of the Fund in the secondary market. This information typically reflects the Fund’s anticipated holdings on the following business day.

Daily access to information concerning the Fund’s portfolio holdings is permitted (i) to certain personnel of those service providers that are involved in portfolio management and providing administrative, operational, risk management, or other support to portfolio management, including affiliated broker-dealers and Authorized Participants; and (ii) to other personnel of the Fund’s investment adviser and the Distributor, administrator, custodian and fund accountant who deal directly with or assist in, functions related to investment management, distribution, administration, custody and fund accounting, as may be necessary to conduct business in the ordinary course in a manner consistent with the iShares Exemptive Orders, agreements

with the Fund and the terms of the Fund’s current registration statement. In addition, the Fund discloses its portfolio holdings and the percentages they represent of the Fund’s net assets at least monthly, and as often as each day the Fund is open for business, at www.iShares.com. More information about this disclosure is available at www.iShares.com.

Portfolio holdings information made available in connection with the creation/redemption process may be provided to other entities that provide services to the Fund in the ordinary course of business after it has been disseminated to the NSCC. From time to time, information concerning portfolio holdings other than portfolio holdings information made available in connection with the creation/redemption process, as discussed above, may be provided to other entities that provide services to the Fund, including rating or ranking organizations, in the ordinary course of business, no earlier than one business day following the date of the information.

The Fund will disclose its complete portfolio holdings schedule in public filings with the SEC within 70 days after the end of each fiscal quarter and will provide that information to shareholders as required by federal securities laws and regulations thereunder. The Fund may, however, voluntarily disclose all or part of its portfolio holdings other than in connection with the creation/redemption process, as discussed above, in advance of required filings with the SEC, provided that such information is made generally available to all shareholders and other interested parties in a manner that is consistent with the above policy for disclosure of portfolio holdings information. Such information may be made available through a publicly-available website or other means that make the information available to all likely interested parties contemporaneously.

The Trust’s Chief Compliance Officer may authorize disclosure of portfolio holdings information pursuant to the above policy and procedures.

The Board reviews the policy and procedures for disclosure of portfolio holdings information at least annually.

Construction and Maintenance of the Underlying Index

A description of the Underlying Index is provided below.

The MSCI Indexes

The MSCI indexes were founded in 1969 by Capital International S.A. as the first international performance benchmarks constructed to facilitate accurate comparison of world markets. The MSCI single country standard equity indexes have covered the world’s developed markets since 1969 and in 1987 MSCI commenced coverage of emerging markets.

Local stock exchanges traditionally calculated their own indexes, which were generally not comparable with one another due to differences in the representation of the local market, mathematical formulas, base dates and methods of adjusting for capital changes. MSCI, however, applies the same calculation methodology to all markets for all single country standard equity indexes, both developed and emerging.

MSCI’s Global Investable Market Indexes (the “MSCI GIMI”) provide exhaustive coverage and non-overlapping market segmentation by market capitalization size and by style. The MSCI GIMI intends to target approximately 99% coverage of the free-float adjusted market capitalization in each market of large, mid and small cap securities.

  • MSCI Global Standard Indexes cover all investable large and mid cap securities by including approximately 85% of each market’s free-float adjusted market capitalization.
  • MSCI Global Small Cap Indexes provide coverage to all companies with a market capitalization below that of the companies in the MSCI Global Standard Indexes by including above and beyond the coverage of the MSCI Global Standard Indexes.

MSCI Global Investable Market Indexes

Selection Criteria. MSCI’s index construction process involves: (i) defining the equity universe; (ii) determining the market investable equity universe for each market; (iii) determining market capitalization size segments for each market; (iv) applying final size segment investability requirements; and (v) applying index continuity rules for the MSCI Global Standard Index.

Defining the Equity Universe. MSCI begins with securities listed in countries in the MSCI GIMI. Of these countries, as of August 31, 2011, 24 are classified as developed markets, 21 as emerging markets, and 31 as frontier markets. All listed equity securities and listed securities that exhibit characteristics of equity securities, except mutual funds, exchange traded funds, equity derivatives, limited partnerships and most investment trusts, are eligible for inclusion in the equity universe. Real estate investment trusts (“REITs”) in some countries and certain income trusts in Canada are also eligible for inclusion. Each company and its securities (i.e., share classes) are classified in only one country.

Determining the Market Investable Equity Universe for each Market. The equity universe in any market is derived by applying investability screens to individual companies and securities in the equity universe of that market. Some investability requirements are applied at the individual security level and some at the overall company level, represented by the aggregation of individual securities of the company. As a result, the inclusion or exclusion of one security does not imply the automatic inclusion or exclusion of other securities of the same company.

Determining Market Capitalization Size Segments for each Market. In each market, MSCI creates an Investable Market Index, Standard Index, Large Cap Index, Mid Cap Index and Small Cap Index. The MSCI Global Standard Index is the aggregation of the Large Cap Index and Mid Cap Index. The MSCI GIMI is the aggregation of the MSCI Global Standard Index and MSCI Global Small Cap Index. In order to create size components that can be meaningfully aggregated into composites, individual market size segments balance the following two objectives:

  • Achieving global size integrity by ensuring that companies of comparable and relevant sizes are included in a given size segment across all markets in a composite index; and
  • Achieving consistent market coverage by ensuring that each market’s size segment is represented in its proportional weight in the composite universe.

Applying Final Size Segment Investability Requirements. In order to enhance replicability of the indexes, additional size segment investability requirements are set for the MSCI GIMI and MSCI Global Standard Index. These investability requirements include minimum free float market capitalization, minimum liquidity, minimum foreign limits and minimum length of trading.

Applying Index Continuity Rules for the Standard Index. In order to achieve index continuity as well as provide some basic level of diversification within a market index, notwithstanding the effect of other index construction rules contained herein, a minimum number of five constituents will be maintained for a developed market Standard Index and a minimum number of three constituents will be maintained for an emerging market Standard Index.

Weighting. All indexes of the MSCI GIMI are free-float weighted, i.e., companies are included in the indexes at the value of their free public float (free float multiplied by security price).

Regional Weights. Market capitalization weighting, combined with a consistent target of approximately 99% of free-float adjusted market capitalization, helps ensure that each country’s weight in regional and international indexes approximates its weight in the total universe of developing and emerging markets. A market is equivalent to a single country except for Europe, where all markets are aggregated into a single market for index construction purposes. Individual country indexes of the European developed markets are derived from the constituents of the MSCI GIMI Europe Index.

Free Float. MSCI defines the free float of a security as the proportion of shares outstanding that are deemed to be available for purchase in the public equity markets by international investors. In practice, limitations on free float available to international investors include: (i) strategic and other shareholdings not considered part of available free float; and (ii) limits on share ownership for foreigners.

Under MSCI’s free-float adjustment methodology, a constituent’s inclusion factor is equal to its estimated free float rounded-up to the closest 5% for constituents with free float equal to or exceeding 15%. For example, a constituent security with a

free float of 23.2% will be included in the index at 25% of its market capitalization. For securities with a free float of less than 15%, the estimated free float is adjusted to the nearest 1%.

Price and Exchange Rates

Prices. The prices used to calculate all MSCI indexes are the official exchange closing prices or those figures accepted as such. MSCI reserves the right to use an alternative pricing source on any given day.

Exchange Rates. Since July 2000, MSCI uses the WM/Reuters Closing Spot Rates taken at 4:00 p.m. London time. In case WM/Reuters does not provide rates for specific markets on given days (for example, Christmas Day and New Year’s Day), the previous business day’s rates are normally used. MSCI independently monitors the exchange rates on all its indices. MSCI may under exceptional circumstances elect to use alternative sources of exchange rates if the WM/Reuters rates are not available, or if MSCI determines that the WM/Reuters rates are not reflective of market circumstances for a given currency on a particular day. In such circumstances, an announcement would be sent to clients with the related information. If appropriate, MSCI may conduct a consultation with the investment community to gather feedback on the most relevant exchange rate.

Changes to the Indexes. The MSCI GIMI is maintained with the objective of reflecting, on a timely basis, the evolution of the underlying equity markets. In maintaining the MSCI indexes, emphasis is also placed on continuity, replicability and minimizing turnover in the indexes. Maintaining the MSCI indexes involves many aspects, including (i) additions to, and deletions from, the indexes; (ii) changes in number of shares; and (iii) changes in inclusion factors as a result of updated free float estimates.

Index maintenance can be described by three broad categories of changes:

  • Semi-Annual Index Reviews (“SAIRs”), conducted on a fixed semi-annual timetable that systematically reassess the various dimensions of the equity universe for all markets;
  • Quarterly Index Reviews (“QIRs”), aimed at promptly reflecting other significant market events; and
  • Ongoing event-related changes, such as mergers, acquisitions, spin-offs, bankruptcies, reorganizations and other similar corporate events, which generally are implemented in the indexes as they occur.

Potential changes in the status of countries (stand-alone, frontier, emerging and developed) follow their own implementation time tables.

MSCI conducts SAIRs generally as of the close of the last business day of May and November. During the SAIRs, MSCI updates the investable equity universe and reassesses size segmentation investability requirements. MSCI also conducts QIRs generally as of the close of the last business day of February and August. During the QIRs, MSCI reflects changes in the index that were not captured at the time of their actual occurrence, but are significant enough to be included before the next SAIR. The results of the SAIR and QIR are generally announced at least ten business days in advance of implementation.

MSCI All Country Asia ex Japan Index

Number of Components: approximately 699

Index Description. As of September 30, 2011, the Underlying Index is a free float-adjusted market capitalization index designed to measure equity performance of the following 12 developed and emerging market countries or regions: Australia, China, Hong Kong, India, Indonesia, Malaysia, New Zealand, the Philippines, Singapore, South Korea, Taiwan and Thailand.

Additional Information. “MSCI,” “Morgan Stanley Capital International,” “MSCI Index” and MSCI All Country Asia ex Japan Index are service marks of MSCI Inc. and have been licensed for use by BTC. The Fund is not sponsored, endorsed, sold or promoted by MSCI Inc. Nor does MSCI Inc. make any representation regarding the advisability of investing in the Fund.

Investment Limitations

The Board has adopted as a non-fundamental policy the investment objective of the Fund. Therefore, the Fund may change its investment objective and its Underlying Index without a shareholder vote. The Board has adopted as fundamental policies the following numbered investment restrictions, which cannot be changed without the approval of the holders of a majority of the Fund’s outstanding voting securities. A vote of a majority of the outstanding voting securities is defined in the 1940

Act as the lesser of (a) 67% or more of the voting securities present at a fund meeting, if the holders of more than 50% of the outstanding voting securities are present or represented by proxy and (b) more than 50% of outstanding voting securities of the fund.

The Fund will not:

1. Concentrate its investments (i.e., invest 25% or more of its total assets in the securities of a particular industry or group of industries), except that the Fund will concentrate to approximately the same extent that the Underlying Index concentrates in the securities of such particular industry or group of industries. For purposes of this limitation, securities of the U.S. government (including its agencies and instrumentalities), repurchase agreements collateralized by U.S. government securities, and securities of state or municipal governments and their political subdivisions are not considered to be issued by members of any industry.
2. Borrow money, except that (i) the Fund may borrow from banks for temporary or emergency (not leveraging) purposes, including the meeting of redemption requests which might otherwise require the untimely disposition of securities; and (ii) the Fund may, to the extent consistent with its investment policies, enter into repurchase agreements, reverse repurchase agreements, forward roll transactions and similar investment strategies and techniques. To the extent that it engages in transactions described in (i) and (ii), the Fund will be limited so that no more than 33 1/3% of the value of its total assets (including the amount borrowed) is derived from such transactions. Any borrowings which come to exceed this amount will be reduced in accordance with applicable law.
3. Issue any senior security, except as permitted under the 1940 Act, as amended, and as interpreted, modified or otherwise permitted by regulatory authority having jurisdiction, from time to time.
4. Make loans, except as permitted under the 1940 Act, as interpreted, modified or otherwise permitted by regulatory authority having jurisdiction, from time to time.
5. Purchase or sell real estate unless acquired as a result of ownership of securities or other instruments (but this restriction shall not prevent the Fund from investing in securities of companies engaged in the real estate business or securities or other instruments backed by real estate or mortgages), or commodities or commodity contracts (but this restriction shall not prevent the Fund from trading in futures contracts and options on futures contracts, including options on currencies to the extent consistent with the Fund’s investment objective and policies).
6. Engage in the business of underwriting securities issued by other persons, except to the extent that the Fund may technically be deemed to be an underwriter under the 1933 Act, in disposing of portfolio securities.
In addition to the investment restrictions adopted as fundamental policies set forth above, the Fund has adopted a non-fundamental policy not to invest in the securities of a company for the purpose of exercising management or control or purchase or otherwise acquire any illiquid security, except as permitted under the 1940 Act, which currently permits up to 15% of the Fund’s net assets to be invested in illiquid securities (calculated at the time of investment).

BFA monitors the liquidity of restricted securities in the Fund’s portfolio. In reaching liquidity decisions, BFA considers the following factors:

  • The frequency of trades and quotes for the security;
  • The number of dealers wishing to purchase or sell the security and the number of other potential purchasers;
  • Dealer undertakings to make a market in the security; and
  • The nature of the security and the nature of the marketplace in which it trades (e.g., the time needed to dispose of the security, the method of soliciting offers and the mechanics of transfer).

If any percentage restriction described above is complied with at the time of an investment, a later increase or decrease in percentage resulting from a change in values of assets will not constitute a violation of such restriction, except that certain percentage limitations will be observed continuously in accordance with applicable law.

The Fund has adopted a non-fundamental investment policy in accordance with Rule 35d-1 under the 1940 Act to invest, under normal circumstances, at least 80% of the value of its net assets, plus the amount of any borrowings for investment purposes, in securities of the Underlying Index or in Depositary Receipts representing securities in the Underlying Index. The Fund also has adopted a policy to provide its shareholders with at least 60 days’ prior written notice of any change in such policy. If, subsequent to an investment, the 80% requirement is no longer met, the Fund’s future investments will be made in a manner that will bring the Fund into compliance with this policy.

Continuous Offering

The method by which Creation Units are created and traded may raise certain issues under applicable securities laws. Because new Creation Units are issued and sold by the Fund on an ongoing basis, at any point a “distribution,” as such term is used in the 1933 Act, may occur. Broker-dealers and other persons are cautioned that some activities on their part may, depending on the circumstances, result in their being deemed participants in a distribution in a manner that could render them statutory underwriters and subject them to the prospectus delivery requirement and liability provisions of the 1933 Act.

For example, a broker-dealer firm or its client may be deemed a statutory underwriter if it takes Creation Units after placing an order with the Distributor, breaks them down into constituent shares and sells such shares directly to customers or if it chooses to couple the creation of new shares with an active selling effort involving solicitation of secondary market demand for shares. A determination of whether one is an underwriter for purposes of the 1933 Act must take into account all the facts and circumstances pertaining to the activities of the broker-dealer or its client in the particular case and the examples mentioned above should not be considered a complete description of all the activities that could lead to a categorization as an underwriter.

Broker-dealer firms should also note that dealers who are not “underwriters” but are effecting transactions in shares, whether or not participating in the distribution of shares, generally are required to deliver a prospectus. This is because the prospectus delivery exemption in Section 4(3) of the 1933 Act is not available in respect of such transactions as a result of Section 24(d) of the 1940 Act. Firms that incur a prospectus delivery obligation with respect to shares of the Fund are reminded that, pursuant to Rule 153 under the 1933 Act, a prospectus delivery obligation under Section 5(b)(2) of the 1933 Act owed to an exchange member in connection with a sale on the Listing Exchange is satisfied by the fact that the prospectus is available at the Listing Exchange upon request. The prospectus delivery mechanism provided in Rule 153 is available only with respect to transactions on an exchange.

Management

The Board has concluded that, based on each Trustee’s experience, qualifications, attributes or skills on an individual basis and in combination with those of the other Trustees, each Trustee should serve as a Trustee of the Board. Among the attributes common to all Trustees are their ability to review critically, evaluate, question and discuss information provided to them, to interact effectively with the Fund’s investment adviser, other service providers, counsel and the independent registered public accounting firm, and to exercise effective business judgment in the performance of their duties as Trustees. A Trustee’s ability to perform his or her duties effectively may have been attained through the Trustee’s educational background or professional training; business, consulting, public service or academic positions; experience from service as a board member of the Fund and the other funds in the Trust (and any predecessor funds), other investment funds, public

Board – Leadership Structure and Oversight Responsibilities

Overall responsibility for oversight of the Fund rests with the Board. The Board has engaged BFA to manage the Fund on a day-to-day basis. The Board is responsible for overseeing BFA and other service providers in the operations of the Fund in accordance with the provisions of the 1940 Act, applicable provisions of state and other laws and the Trust’s charter. The Board is currently composed of nine members, seven of whom are Independent Trustees (defined below). The Board

currently conducts regular meetings four times a year. In addition, the Board frequently holds special in-person or telephonic meetings or informal conference calls to discuss specific matters that may arise or require action between regular meetings. The Independent Trustees meet regularly outside the presence of management, in executive session or with other service providers to the Trust.

The Board has appointed an Independent Trustee to serve in the role of Chairman. The Chairman’s role is to preside at all meetings of the Board and to act as a liaison with service providers, officers, attorneys, and other Trustees generally between meetings. The Chairman may also perform such other functions as may be delegated by the Board from time to time. The Board has established a Nominating and Governance Committee and an Audit Committee to assist the Board in the oversight and direction of the business and affairs of the Fund, and from time to time may establish ad-hoc committees or informal working groups to review and address the policies and practices of the Fund with respect to certain specified matters. The Board and each standing Committee conduct annual assessments of their oversight function and structure. The Board has determined that the Board’s leadership structure is appropriate because it allows the Board to exercise independent judgment over management and it allocates areas of responsibility among committees of Independent Trustees and the full Board to enhance effective oversight.

Day-to-day risk management with respect to the Fund is the responsibility of BFA or other service providers (depending on the nature of the risk), subject to the supervision of BFA. The Fund is subject to a number of risks, including investment, compliance, operational and valuation risks, among others. While there are a number of risk management functions performed by BFA and other service providers, as applicable, it is not possible to eliminate all of the risks applicable to the Fund. The Trustees have an oversight role in this area, satisfying themselves that risk management processes are in place and operating effectively. Risk oversight forms part of the Board’s general oversight of the Fund and is addressed as part of various Board and committee activities. The Board, directly or through a committee, also reviews reports from, among others, management and the independent registered public accounting firm for the Trust, as appropriate, regarding risks faced by the Fund and management’s risk functions. The Board has appointed a Chief Compliance Officer who oversees the implementation and testing of the Trust’s compliance program and reports to the Board regarding compliance matters for the Trust and its principal service providers. In testing and maintaining the compliance program, the Chief Compliance Officer assesses key compliance risks affecting the Fund, and addresses them in reports to the Board. The Independent Trustees have engaged independent legal counsel to assist them in performing their oversight responsibilities.

Committees of the Board of Trustees. Each Trustee who is not an interested person (as defined in the 1940 Act) of the Trust (“Independent Trustee”) serves on the Audit Committee and the Nominating and Governance Committee of the Board. The purposes of the Audit Committee are to assist the Board (i) in its oversight of the Trust’s accounting and financial reporting principles and policies and related controls and procedures maintained by or on behalf of the Trust; (ii) in its oversight of the Trust’s financial statements and the independent audit thereof; (iii) in selecting, evaluating and, where deemed appropriate, replacing the independent accountants (or nominating the independent accountants to be proposed for shareholder approval in any proxy statement); (iv) in evaluating the independence of the independent accountants; (v) in complying with legal and regulatory requirements that relate to the Trust’s accounting and financial reporting, internal controls and independent audits; and (vi) to assume such other responsibilities as may be delegated by the Board. The Audit Committee met five times during the fiscal year ended July 31, 2011.

The Nominating and Governance Committee nominates individuals for Independent Trustee membership on the Board. The Nominating and Governance Committee functions include, but are not limited to, the following: (i) reviewing the qualifications of any person properly identified or nominated to serve as an Independent Trustee; (ii) recommending to the Board and current Independent Trustees the nominee(s) for appointment as an Independent Trustee by the Board and current Independent Trustees and/or for election as Independent Trustees by shareholders to fill any vacancy for a position of Independent Trustee(s) on the Board; (iii) recommending to the Board and current Independent Trustees the size and composition of the Board and Board committees and whether they comply with applicable laws and regulations; (iv) recommending a current Independent Trustee to the Board and current Independent Trustees to serve as Lead Independent Trustee; (v) periodic review of the Board’s retirement policy; and (vi) recommending an appropriate level of compensation for the Independent Trustees for their services as Trustees, members or chairpersons of committees of the Board, Lead Independent Trustee, Chairperson of the Board and any other positions as the Nominating and Governance Committee considers appropriate. The Nominating and Governance Committee does not consider Board nomination(s) recommended by shareholders (acting solely in their capacity as a shareholder and not in any other capacity).

Potential Conflicts of Interest. Barclays PLC (“Barclays”) and The PNC Financial Services Group, Inc. (“PNC”), each has a significant economic interest in BlackRock, Inc., the parent of BFA, the Fund’s investment adviser. PNC is considered to be an affiliate of BlackRock, Inc., under the 1940 Act. Certain activities of BlackRock Advisors, LLC, BlackRock, Inc. and their affiliates (collectively, “BlackRock”) and PNC and its affiliates (collectively, “PNC” and together with BlackRock, “Affiliates”), and those of Barclays and its affiliates (collectively, the “Barclays Entities”), with respect to the Fund and/or other accounts managed by BlackRock, PNC or Barclays Entities, may give rise to actual or perceived conflicts of interest such as those described below.

BlackRock is one of the world’s largest asset management firms. PNC is a diversified financial services organization spanning the retail, business and corporate markets. Barclays is a major global financial services provider engaged in a range of activities, including retail and commercial banking, credit cards, investment banking, and wealth management. BlackRock and PNC are affiliates of one another under the 1940 Act. BlackRock, PNC, Barclays and their respective affiliates (including, for these purposes, their directors, partners, trustees, managing members, officers and employees), including the entities and personnel who may be involved in the investment activities and business operations of the Fund, are engaged worldwide in businesses, including equity, fixed income, cash management and alternative investments. These are considerations of which investors in the Fund should be aware, and which may cause conflicts of interest that could disadvantage the Fund and its shareholders. These activities and interests include potential multiple advisory, transactional, financial and other interests in securities and other instruments that may be purchased or sold by the Fund.

BlackRock and its Affiliates, as well as the Barclays Entities, have proprietary interests in, and may manage or advise with respect to, accounts or funds (including separate accounts and other funds and collective investment vehicles) that have investment objectives similar to those of the Fund and/or that engage in transactions in the same types of securities, currencies and instruments as the Fund. One or more Affiliates and Barclays Entities are also major participants in the global currency, equities, swap and fixed income markets, in each case both on a proprietary basis and for the accounts of customers. As such, one or more Affiliates or Barclays Entities are or may be actively engaged in transactions in the same securities, currencies, and instruments in which the Fund invests. Such activities could affect the prices and availability of the securities, currencies, and instruments in which the Fund invests, which could have an adverse impact on the Fund’s performance. Such transactions, particularly in respect of most proprietary accounts or customer accounts, will be executed independently of the Fund’s transactions and thus at prices or rates that may be more or less favorable than those obtained by the Fund. When BlackRock and its Affiliates purchase or sell the same assets for their managed accounts, including the Fund, the assets actually purchased or sold may be allocated among the accounts on a basis determined in their good faith discretion to be equitable. In some cases, this system may adversely affect the size or price of the assets purchased or sold for the Fund. In addition, transactions in investments by one or more other accounts managed by BlackRock or its Affiliates or a Barclays Entity may have the effect of diluting or otherwise disadvantaging the values, prices or investment strategies of the Fund, particularly, but not limited to, with respect to small capitalization, emerging market or less liquid strategies. This may

occur when investment decisions regarding the Fund are based on research or other information that is also used to support decisions for other accounts. When BlackRock or its Affiliates or a Barclays Entity implements a portfolio decision or strategy on behalf of another account ahead of, or contemporaneously with, similar decisions or strategies for the Fund, market impact, liquidity constraints, or other factors could result in the Fund receiving less favorable trading results and the costs of implementing such decisions or strategies could be increased or the Fund could otherwise be disadvantaged. BlackRock or its Affiliates or a Barclays Entity may, in certain cases, elect to implement internal policies and procedures designed to limit such consequences, which may cause the Fund to be unable to engage in certain activities, including purchasing or disposing of securities, when it might otherwise be desirable for it to do so.

Conflicts may also arise because portfolio decisions regarding the Fund may benefit other accounts managed by BlackRock or its Affiliates or a Barclays Entity. For example, the sale of a long position or establishment of a short position by the Fund may impair the price of the same security sold short by (and therefore benefit) one or more Affiliates or Barclays Entities or their other accounts, and the purchase of a security or covering of a short position in a security by the Fund may increase the price of the same security held by (and therefore benefit) one or more Affiliates or Barclays Entities or their other accounts.

BlackRock and its Affiliates or a Barclays Entity and their clients may pursue or enforce rights with respect to an issuer in which the Fund has invested, and those activities may have an adverse effect on the Fund. As a result, prices, availability, liquidity and terms of the Fund’s investments may be negatively impacted by the activities of BlackRock or its Affiliates or a Barclays Entity or their clients, and transactions for the Fund may be impaired or effected at prices or terms that may be less favorable than would otherwise have been the case.

The results of the Fund’s investment activities may differ significantly from the results achieved by BlackRock and its Affiliates or the Barclays Entities for their proprietary accounts or other accounts (including investment companies or collective investment vehicles) managed or advised by them. It is possible that one or more Affiliate- or Barclays Entity-managed accounts and such other accounts will achieve investment results that are substantially more or less favorable than the results achieved by the Fund. Moreover, it is possible that the Fund will sustain losses during periods in which one or more Affiliates or Barclays Entity-managed accounts achieve significant profits on their trading for proprietary or other accounts. The opposite result is also possible. The investment activities of one or more Affiliates or Barclays Entities for their proprietary accounts and accounts under their management may also limit the investment opportunities for the Fund in certain emerging and other markets in which limitations are imposed upon the amount of investment, in the aggregate or in individual issuers, by affiliated foreign investors.

From time to time, the Fund’s activities may also be restricted because of regulatory restrictions applicable to one or more Affiliates or Barclays Entities, and/or their internal policies designed to comply with such restrictions. As a result, there may be periods, for example, when BlackRock, and/or one or more Affiliates or Barclays Entities, will not initiate or recommend certain types of transactions in certain securities or instruments with respect to which BlackRock and/or one or more Affiliates or Barclays Entities are performing services or when position limits have been reached.

In connection with its management of the Fund, BlackRock may have access to certain fundamental analysis and proprietary technical models developed by one or more Affiliates or Barclays Entities. BlackRock will not be under any obligation, however, to effect transactions on behalf of the Fund in accordance with such analysis and models. In addition, neither BlackRock nor any of its Affiliates, nor any Barclays Entity, will have any obligation to make available any information regarding their proprietary activities or strategies, or the activities or strategies used for other accounts managed by them, for the benefit of the management of the Fund and it is not anticipated that BlackRock will have access to such information for the purpose of managing the Fund. The proprietary activities or portfolio strategies of BlackRock and its Affiliates and the Barclays Entities, or the activities or strategies used for accounts managed by them or other customer accounts could conflict with the transactions and strategies employed by BlackRock in managing the Fund.

In addition, certain principals and certain employees of BlackRock are also principals or employees of Affiliates. As a result, the performance by these principals and employees of their obligations to such other entities may be a consideration of which investors in the Fund should be aware.

BlackRock may enter into transactions and invest in securities, instruments and currencies on behalf of the Fund in which customers of BlackRock or its Affiliates or a Barclays Entity, or, to the extent permitted by the SEC, BlackRock or another Affiliate or a Barclays Entity, serves as the counterparty, principal or issuer. In such cases, such party’s interests in the transaction will be adverse to the interests of the Fund, and such party may have no incentive to assure that the Fund obtains the best possible prices or terms in connection with the transactions. In addition, the purchase, holding and sale of such

investments by the Fund may enhance the profitability of BlackRock or its Affiliates or a Barclays Entity. One or more Affiliates or Barclays Entities may also create, write or issue derivatives for their customers, the underlying securities, currencies or instruments of which may be those in which the Fund invests or which may be based on the performance of the Fund. The Fund may, subject to applicable law, purchase investments that are the subject of an underwriting or other distribution by one or more Affiliates or Barclays Entities and may also enter into transactions with other clients of an Affiliate or Barclays Entity where such other clients have interests adverse to those of the Fund.

At times, these activities may cause departments of BlackRock or its Affiliates or a Barclays Entity to give advice to clients that may cause these clients to take actions adverse to the interests of the Fund. To the extent affiliated transactions are permitted, the Fund will deal with BlackRock and its Affiliates or Barclays Entities on an arms-length basis. BlackRock or its Affiliates or a Barclays Entity may also have an ownership interest in certain trading or information systems used by the Fund. The Fund’s use of such trading or information systems may enhance the profitability of BlackRock and its Affiliates or Barclays Entities.

One or more Affiliates or one of the Barclays Entities may act as broker, dealer, agent, lender or adviser or in other commercial capacities for the Fund. It is anticipated that the commissions, mark-ups, mark-downs, financial advisory fees, underwriting and placement fees, sales fees, financing and commitment fees, brokerage fees, other fees, compensation or profits, rates, terms and conditions charged by an Affiliate or Barclays Entity will be in its view commercially reasonable, although each Affiliate or Barclays Entity, including its sales personnel, will have an interest in obtaining fees and other amounts that are favorable to the Affiliate or Barclays Entity and such sales personnel.

Subject to applicable law, the Affiliates and Barclays Entities (and their personnel and other distributors) will be entitled to retain fees and other amounts that they receive in connection with their service to the Fund as broker, dealer, agent, lender, adviser or in other commercial capacities and no accounting to the Fund or its shareholders will be required, and no fees or other compensation payable by the Fund or its shareholders will be reduced by reason of receipt by an Affiliate or Barclays Entity of any such fees or other amounts.

When an Affiliate or Barclays Entity acts as broker, dealer, agent, adviser or in other commercial capacities in relation to the Fund, the Affiliate or Barclays Entity may take commercial steps in its own interests, which may have an adverse effect on the Fund. The Fund will be required to establish business relationships with its counterparties based on the Fund’s own credit standing. Neither BlackRock nor any of the Affiliates, nor any Barclays Entity, will have any obligation to allow their credit to be used in connection with the Fund’s establishment of its business relationships, nor is it expected that the Fund’s counterparties will rely on the credit of BlackRock or any of the Affiliates or Barclays Entities in evaluating the Fund’s creditworthiness.

Purchases and sales of securities for the Fund may be bunched or aggregated with orders for other BlackRock client accounts. BlackRock, however, is not required to bunch or aggregate orders if portfolio management decisions for different accounts are made separately, or if it determines that bunching or aggregating is not practicable or required, or in cases involving client direction.

Prevailing trading activity frequently may make impossible the receipt of the same price or execution on the entire volume of securities purchased or sold. When this occurs, the various prices may be averaged, and the Fund will be charged or credited with the average price. Thus, the effect of the aggregation may operate on some occasions to the disadvantage of the Fund. In addition, under certain circumstances, the Fund will not be charged the same commission or commission equivalent rates in connection with a bunched or aggregated order.

BlackRock may select brokers (including, without limitation, Affiliates or Barclays Entities) that furnish BlackRock, the Fund, other BlackRock client accounts or other Affiliates or Barclays Entities or personnel, directly or through correspondent relationships, with research or other appropriate services which provide, in BlackRock’s view, appropriate assistance to BlackRock in the investment decision-making process (including with respect to futures, fixed-price offerings and over-the-counter transactions). Such research or other services may include, to the extent permitted by law, research reports on companies, industries and securities; economic and financial data; financial publications; proxy analysis; trade industry seminars; computer data bases; research-oriented software and other services and products. Research or other services obtained in this manner may be used in servicing any or all of the Fund and other BlackRock client accounts, including in connection with BlackRock client accounts other than those that pay commissions to the broker relating to the research or other service arrangements. Such products and services may disproportionately benefit other BlackRock client accounts relative to the Fund based on the amount of brokerage commissions paid by the Fund and such other BlackRock client

accounts. For example, research or other services that are paid for through one client’s commissions may not be used in managing that client’s account. In addition, other BlackRock client accounts may receive the benefit, including disproportionate benefits, of economies of scale or price discounts in connection with products and services that may be provided to the Fund and to such other BlackRock client accounts. To the extent that BlackRock uses soft dollars, it will not have to pay for those products and services itself.

BlackRock may receive research that is bundled with the trade execution, clearing, and/or settlement services provided by a particular broker-dealer. To the extent that BlackRock receives research on this basis, many of the same conflicts related to traditional soft dollars may exist. For example, the research effectively will be paid by client commissions that also will be used to pay for the execution, clearing, and settlement services provided by the broker-dealer and will not be paid by BlackRock.

BlackRock may endeavor to execute trades through brokers who, pursuant to such arrangements, provide research or other services in order to ensure the continued receipt of research or other services BlackRock believes are useful in its investment decision-making process. BlackRock may from time to time choose not to engage in the above described arrangements to varying degrees. BlackRock may also enter into commission sharing arrangements under which BlackRock may execute transactions through a broker-dealer, including, where permitted, an Affiliate or Barclays Entity, and request that the broker-dealer allocate a portion of the commissions or commission credits to another firm that provides research to BlackRock. To the extent that BlackRock engages in commission sharing arrangements, many of the same conflicts related to traditional soft dollars may exist.

BlackRock may utilize certain electronic crossing networks (“ECNs”) in executing client securities transactions for certain types of securities. These ECNs may charge fees for their services, including access fees and transaction fees. The transaction fees, which are similar to commissions or markups/markdowns, will generally be charged to clients and, like commissions and markups/markdowns, would generally be included in the cost of the securities purchased. Access fees may be paid by BlackRock even though incurred in connection with executing transactions on behalf of clients, including the Fund. In certain circumstances, ECNs may offer volume discounts that will reduce the access fees typically paid by BlackRock. This would have the effect of reducing the access fees paid by BlackRock. BlackRock will only utilize ECNs consistent with its obligation to seek to obtain best execution in client transactions.

BlackRock has adopted policies and procedures designed to prevent conflicts of interest from influencing proxy voting decisions that it makes on behalf of advisory clients, including the Fund, and to help ensure that such decisions are made in accordance with BlackRock’s fiduciary obligations to its clients. Nevertheless, notwithstanding such proxy voting policies and procedures, actual proxy voting decisions of BlackRock may have the effect of favoring the interests of other clients or businesses of other divisions or units of BlackRock and/or its Affiliates or a Barclays Entity, provided that BlackRock believes such voting decisions to be in accordance with its fiduciary obligations. For a more detailed discussion of these policies and procedures, see the Proxy Voting Policy section of this SAI.

It is also possible that, from time to time, BlackRock or its Affiliates or a Barclays Entity may, although they are not required to, purchase and hold shares of the Fund. Increasing the Fund’s assets may enhance investment flexibility and diversification and may contribute to economies of scale that tend to reduce the Fund’s expense ratio. BlackRock and its Affiliates or Barclays Entities reserve the right to redeem at any time some or all of the shares of the Fund acquired for their own accounts. A large redemption of shares of the Fund by BlackRock or its Affiliates or by a Barclays Entity could significantly reduce the asset size of the Fund, which might have an adverse effect on the Fund’s investment flexibility, portfolio diversification and expense ratio. BlackRock will consider the effect of redemptions on the Fund and other shareholders in deciding whether to redeem its shares.

It is possible that the Fund may invest in securities of companies with which an Affiliate or a Barclays Entity has or is trying to develop investment banking relationships as well as securities of entities in which BlackRock or its Affiliates or a Barclays Entity has significant debt or equity investments or in which an Affiliate or Barclays Entity makes a market. The Fund also may invest in securities of companies to which an Affiliate or a Barclays Entity provides or may some day provide research coverage. Such investments could cause conflicts between the interests of the Fund and the interests of other clients of BlackRock or its Affiliates or a Barclays Entity. In making investment decisions for the Fund, BlackRock is not permitted to obtain or use material non-public information acquired by any division, department or Affiliate of BlackRock or of a Barclays Entity in the course of these activities. In addition, from time to time, the activities of an Affiliate or a Barclays Entity may limit the Fund’s flexibility in purchases and sales of securities. When an Affiliate is engaged in an underwriting or other distribution

of securities of an entity, BlackRock may be prohibited from purchasing or recommending the purchase of certain securities of that entity for the Fund.

BlackRock and its Affiliates and the Barclays Entities, their personnel and other financial service providers may have interests in promoting sales of the Fund. With respect to BlackRock and its Affiliates and Barclays Entities and their personnel, the remuneration and profitability relating to services to and sales of the Fund or other products may be greater than remuneration and profitability relating to services to and sales of certain funds or other products that might be provided or offered. BlackRock and its Affiliates or Barclays Entities and their sales personnel may directly or indirectly receive a portion of the fees and commissions charged to the Fund or its shareholders. BlackRock and its advisory or other personnel may also benefit from increased amounts of assets under management. Fees and commissions may also be higher than for other products or services, and the remuneration and profitability to BlackRock or its Affiliates or a Barclays Entity and such personnel resulting from transactions on behalf of or management of the Fund may be greater than the remuneration and profitability resulting from other funds or products.

BlackRock and its Affiliates or a Barclays Entity and their personnel may receive greater compensation or greater profit in connection with an account for which BlackRock serves as an adviser than with an account advised by an unaffiliated investment adviser. Differentials in compensation may be related to the fact that BlackRock may pay a portion of its advisory fee to its Affiliate or to a Barclays Entity, or relate to compensation arrangements, including for portfolio management, brokerage transactions or account servicing. Any differential in compensation may create a financial incentive on the part of BlackRock or its Affiliates or Barclays Entities and their personnel to recommend BlackRock over unaffiliated investment advisers or to effect transactions differently in one account over another.

BlackRock and its Affiliates or a Barclays Entity may provide valuation assistance to certain clients with respect to certain securities or other investments and the valuation recommendations made for their clients’ accounts may differ from the valuations for the same securities or investments assigned by the Fund’s pricing vendors, especially if such valuations are based on broker-dealer quotes or other data sources unavailable to the Fund’s pricing vendors. While BlackRock will generally communicate its valuation information or determinations to the Fund’s pricing vendors and/or fund accountants, there may be instances where the Fund’s pricing vendors or fund accountants assign a different valuation to a security or other investment than the valuation for such security or investment determined or recommended by BlackRock.

As disclosed in more detail in the Determination of Net Asset Value section of the Fund’s Prospectus, when market valuations are not readily available or such valuations do not reflect current market values, the affected investments will be valued using fair value pricing, pursuant to procedures adopted by the Fund’s Board. As a result, the Fund’s sale or redemption of its shares at net asset value, at a time when a holding or holdings are valued by BlackRock (pursuant to Board-adopted procedures) at fair value, may have the effect of diluting or increasing the economic interest of existing shareholders.

To the extent permitted by applicable law, the Fund may invest all or some of its short term cash investments in any money market fund or similarly-managed private fund advised or managed by BlackRock. In connection with any such investments, the Fund, to the extent permitted by the 1940 Act, may pay its share of expenses of a money market fund in which it invests, which may result in the Fund bearing some additional expenses.

BlackRock and its Affiliates or a Barclays Entity and their directors, officers and employees, may buy and sell securities or other investments for their own accounts, and may have conflicts of interest with respect to investments made on behalf of the Fund. As a result of differing trading and investment strategies or constraints, positions may be taken by directors, officers, employees and Affiliates of BlackRock or by Barclays Entities that are the same, different from or made at different times than positions taken for the Fund. To lessen the possibility that the Fund will be adversely affected by this personal trading, the Fund, BFA and BlackRock each has adopted a Code of Ethics in compliance with Section 17(j) of the 1940 Act that restricts securities trading in the personal accounts of investment professionals and others who normally come into possession of information regarding the Fund’s portfolio transactions. Each Code of Ethics can be reviewed and copied at the SEC’s Public Reference Room in Washington, D.C. Information on the operation of the Public Reference Room may be obtained by calling the SEC at (202) 551-8090. Each Code of Ethics is also available on the EDGAR Database on the SEC’s Internet site at http://www.sec.gov, and copies may be obtained, after paying a duplicating fee, by e-mail at publicinfo@sec.gov or by writing the SEC’s Public Reference Section, Washington, DC 20549-1520.

BlackRock and its Affiliates will not purchase securities or other property from, or sell securities or other property to, the Fund, except that the Fund may in accordance with rules adopted under the 1940 Act engage in transactions with accounts that are affiliated with the Fund as a result of common officers, directors, or investment advisers or pursuant to exemptive

orders granted to the Fund and/or BlackRock by the SEC. These transactions would be affected in circumstances in which BlackRock determined that it would be appropriate for the Fund to purchase and another client of BlackRock to sell, or the Fund to sell and another client of BlackRock to purchase, the same security or instrument on the same day. From time to time, the activities of the Fund may be restricted because of regulatory requirements applicable to BlackRock or its Affiliates or a Barclays Entity and/or BlackRock’s internal policies designed to comply with, limit the applicability of, or otherwise relate to such requirements. A client not advised by BlackRock would not be subject to some of those considerations. There may be periods when BlackRock may not initiate or recommend certain types of transactions, or may otherwise restrict or limit their advice in certain securities or instruments issued by or related to companies for which an Affiliate or a Barclays Entity is performing investment banking, market making or other services or has proprietary positions. For example, when an Affiliate is engaged in an underwriting or other distribution of securities of, or advisory services for, a company, the Fund may be prohibited from or limited in purchasing or selling securities of that company. Similar situations could arise if personnel of BlackRock or its Affiliates or a Barclays Entity serve as directors of companies the securities of which the Fund wishes to purchase or sell. However, if permitted by applicable law, the Fund may purchase securities or instruments that are issued by such companies or are the subject of an underwriting, distribution, or advisory assignment by an Affiliate or a Barclays Entity, or in cases in which personnel of BlackRock or its Affiliates or of Barclays Entities are directors or officers of the issuer.

The investment activities of one or more Affiliates or Barclays Entities for their proprietary accounts and for client accounts may also limit the investment strategies and rights of the Fund. For example, in regulated industries, in certain emerging or international markets, in corporate and regulatory ownership definitions, and in certain futures and derivative transactions, there may be limits on the aggregate amount of investment by affiliated investors that may not be exceeded without the grant of a license or other regulatory or corporate consent or, if exceeded, may cause BlackRock, the Fund or other client accounts to suffer disadvantages or business restrictions.

If certain aggregate ownership thresholds are reached or certain transactions undertaken, the ability of BlackRock on behalf of clients (including the Fund) to purchase or dispose of investments, or exercise rights or undertake business transactions, may be restricted by regulation or otherwise impaired. As a result, BlackRock, on behalf of clients (including the Fund), may limit purchases, sell existing investments, or otherwise restrict or limit the exercise of rights (including voting rights) when BlackRock, in its sole discretion, deems it appropriate.

BlackRock and its Affiliates and Barclays Entities may maintain securities indices as part of their product offerings. Index based funds seek to track the performance of securities indices and may use the name of the index in the fund name. Index providers, including BlackRock and its Affiliates and Barclays Entities may be paid licensing fees for use of their index or index name. BlackRock and its Affiliates and Barclays Entities will not be obligated to license their indices to BlackRock, and BlackRock cannot be assured that the terms of any index licensing agreement with BlackRock and its Affiliates and Barclays Entities will be as favorable as those terms offered to other index licensees.

BlackRock and its Affiliates and Barclays Entities may serve as Authorized Participants in the creation and redemption of exchange-traded funds, including funds advised by Affiliates of BlackRock. As described in greater detail in the Creations and Redemptions section of the prospectus, BlackRock and its Affiliates and Barclays Entities may therefore be deemed to be participants in a distribution of iShares funds that could render them statutory underwriters.

Present and future activities of BlackRock and its Affiliates and Barclays Entities, including BlackRock Advisors, LLC, in addition to those described in this section, may give rise to additional conflicts of interest.

Investment Advisory, Administrative and Distribution Services

Investment Adviser. BFA serves as investment adviser to the Fund pursuant to an Investment Advisory Agreement between the Trust, on behalf of the Fund, and BFA. BFA is a California corporation indirectly owned by BlackRock, Inc. and is registered as an investment adviser under the Investment Advisers Act of 1940, as amended. Under the Investment Advisory Agreement, BFA, subject to the supervision of the Board and in conformity with the stated investment policies of the Fund, manages and administers the Trust and the investment of the Fund’s assets. BFA is responsible for placing purchase and sale orders and providing continuous supervision of the investment portfolio of the Fund.

Pursuant to the Investment Advisory Agreement, BFA may, from time to time, in its sole discretion and to the extent permitted by applicable law, appoint one or more sub-advisers, including, without limitation, affiliates of BFA, to perform investment advisory or other services with respect to the Fund. In addition, BFA may delegate certain of its investment advisory functions under the Investment Advisory Agreement to one or more of its affiliates to the extent permitted by applicable law. BFA may terminate any or all sub-advisers or such delegation arrangements in its sole discretion upon appropriate notice at any time to the extent permitted by applicable law.

For its investment advisory services, BFA is entitled to receive a management fee from the Fund corresponding to the Fund’s allocable portion of an aggregate management fee based on the aggregate average daily net assets of the following iShares funds: iShares MSCI All Country Asia ex Japan Index Fund, iShares MSCI BRIC Index Fund, iShares MSCI Emerging Markets Eastern Europe Index Fund, iShares MSCI Emerging Markets Financials Sector Index Fund, iShares MSCI Emerging Markets Index Fund, iShares MSCI Emerging Markets Materials Sector Index Fund, iShares MSCI Emerging Markets Minimum Volatility Index Fund and iShares MSCI Emerging Markets Small Cap Index Fund. The aggregate management fee is calculated as follows: 0.75% per annum of the aggregate net assets less than or equal to $14.0 billion, plus 0.68% per annum of the aggregate net assets over $14.0 billion, up to and including $28.0 billion, plus 0.61% per annum of the aggregate net assets over $28.0 billion, up to and including $42.0 billion, plus 0.56% per annum of the aggregate net assets over $42.0 billion, up to and including $56.0 billion, plus 0.50% per annum of the aggregate net assets over $56.0 billion, up to and including $70.0 billion, plus 0.45% per annum of the aggregate net assets over $70.0 billion, up to and including $84.0 billion plus 0.40% per annum of the aggregate net assets in excess of $84.0 billion.

Pursuant to the Investment Advisory Agreement, BFA is responsible for substantially all expenses of the Fund, including the cost of transfer agency, custody, fund administration, legal, audit and other services. BFA is not responsible for, and the Fund will bear the cost of, interest expense, taxes, brokerage expenses and other expenses connected with the execution of portfolio securities transactions, distribution fees and extraordinary expenses.

For its investment advisory services to the Fund, BFA received a management fee from the Fund, based on a percentage of the Fund’s average daily net assets, at an annual rate of 0.67%.

* The management fee for the fiscal year ended July 31, 2011 was 0.67%. During this period, BFA contractually agreed to waive a portion of its management fee for its investment advisory services to the Fund in an amount equal to the Fund’s Acquired Fund Fees and Expenses. After giving effect to such contractual waiver, the management fee was 0.67%. For the fiscal years ended July 31, 2011, 2010, and 2009, BFA waived $343,993, $74,643 and $34,292, of management fees, respectively.

The Investment Advisory Agreement with respect to the Fund continues in effect for two years from its effective date, and thereafter is subject to annual approval by (i) the Board, or (ii) the vote of a majority of the outstanding voting securities (as defined in the 1940 Act) of the Fund, provided that in either event such continuance also is approved by a majority of the Board who are not interested persons (as defined in the 1940 Act) of the Fund, by a vote cast in person at a meeting called for the purpose of voting on such approval.

The Investment Advisory Agreement with respect to the Fund is terminable without penalty, on 60 days’ notice, by the Board or by a vote of the holders of a majority of the Fund’s outstanding voting securities (as defined in the 1940 Act). The Investment Advisory Agreement is also terminable upon 60 days’ notice by BFA and will terminate automatically in the event of its assignment (as defined in the 1940 Act).

Current interpretations of U.S. federal banking laws and regulations (i) may prohibit BlackRock, Inc., BTC and BFA from controlling or underwriting the shares of the Fund, but (ii) do not prohibit BlackRock, Inc. or BFA generally from acting as an investment adviser, administrator, transfer agent or custodian to the Fund or from purchasing shares as agent for and upon the order of a customer.

BFA believes that it may perform advisory and related services for the Trust without violating applicable banking laws or regulations. However, the legal requirements and interpretations about the permissible activities of banks and their affiliates may change in the future. These changes could prevent BFA from continuing to perform services for the Trust. If this

happens, the Board would consider selecting other qualified firms. Any new investment advisory agreement would be subject to shareholder approval.

If current restrictions on bank activities with mutual funds were relaxed, BFA, or its affiliates, would consider performing additional services for the Trust. BFA cannot predict whether these changes will be enacted, or the terms under which BFA, or its affiliates, might offer to provide additional services.

The Subsidiary has entered into a separate contract with BFA whereby BFA provides investment advisory services to the Subsidiary. BFA does not receive separate compensation from the Subsidiary for providing it with investment advisory services. The Fund pays BFA a management fee based on the Fund’s assets, including the assets invested in the Subsidiary. The Subsidiary has also entered into separate arrangements that provide for the provision of other services to the Subsidiary (including administrative, custody, transfer agency and other services), and BFA shall pay the costs and expenses related to the provision of those services.

Portfolio Managers. As of July 31, 2011, the individuals named as Portfolio Managers in the Fund’s Prospectus were also primarily responsible for the day-to-day management of other iShares funds and certain other types of portfolios and/or accounts as indicated in the tables below:

Each of the portfolios or accounts for which the Portfolio Managers are primarily responsible for the day-to-day management seeks to track the rate of return, risk profile and other characteristics of independent third-party indexes by either replicating the same combination of securities that constitute those indexes or through a representative sampling of the securities that constitute those indexes based on objective criteria and data. Pursuant to BTC and BFA policy, investment opportunities are allocated equitably among the Fund and other portfolios and accounts. For example, under certain circumstances, an investment opportunity may be restricted due to limited supply on the market, legal constraints or other factors, in which event the investment opportunity will be allocated equitably among those portfolios and accounts, including the Fund

seeking such investment opportunity. As a consequence, from time to time the Fund may receive a smaller allocation of an investment opportunity than it would have if the Portfolio Managers and BFA and its affiliates did not manage other portfolios or accounts.

Like the Fund, the other portfolios or accounts for which the Portfolio Managers are primarily responsible for the day-to-day portfolio management generally pay an asset-based fee to BFA or BTC, as applicable, for its advisory services. One or more of those other portfolios or accounts, however, may pay BTC an incentive-based fee in lieu of, or in addition to, an asset-based fee for its advisory services. A portfolio or account with an incentive-based fee would pay BTC a portion of that portfolio’s or account’s gains, or would pay BTC more for its services than would otherwise be the case if BTC meets or exceeds specified performance targets. By their nature, incentive-based fee arrangements could present an incentive for BTC to devote greater resources, and allocate more investment opportunities, to the portfolios or accounts that have those fee arrangements, relative to other portfolios or accounts, in order to earn larger fees. Although BTC has an obligation to allocate resources and opportunities equitably among portfolios and accounts and intends to do so, shareholders of the Fund should be aware that, as with any group of portfolios and accounts managed by an investment adviser and/or its affiliates pursuant to varying fee arrangements, including incentive-based fee arrangements, there is the potential for a conflict of interest that may result in the Portfolio Managers’ favoring those portfolios or accounts with incentive-based fee arrangements.

The tables below show, for each Portfolio Manager, the number of portfolios or accounts of the types set forth in the above tables and the aggregate of total assets in those portfolios or accounts with respect to which the investment management fees are based on the performance of those portfolios or accounts as of July 31, 2011:

The discussion below describes the Portfolio Managers’ compensation as of July 31, 2011.

Portfolio Manager Compensation Overview

Base compensation. Generally, portfolio managers receive base compensation based on their seniority and/or their position with the firm. Senior portfolio managers who perform additional management functions within the portfolio management group or within BlackRock may receive additional compensation for serving in these other capacities.

Discretionary Incentive Compensation. Discretionary incentive compensation is a function of several components: the performance of BlackRock, Inc., the performance of the portfolio manager’s group within BlackRock, the investment performance, including risk-adjusted returns, of the firm’s assets under management or supervision by that portfolio manager relative to predetermined benchmarks, and the individual’s seniority, role within the portfolio management team, teamwork and contribution to the overall performance of these portfolios and BlackRock.

Distribution of Discretionary Incentive Compensation. Discretionary incentive compensation is distributed to portfolio managers in a combination of cash and BlackRock, Inc. restricted stock units which vest ratably over a number of years. The BlackRock, Inc. restricted stock units, if properly vested, will be settled in BlackRock, Inc. common stock. Typically, the cash bonus, when combined with base salary, represents more than 60% of total compensation for the portfolio managers. Paying a portion of annual bonuses in stock puts compensation earned by a portfolio manager for a given year “at risk” based on BlackRock’s ability to sustain and improve its performance over future periods.

From time to time, long-term incentive equity awards are granted to certain key employees to aid in retention, align their interests with long-term shareholder interests and motivate performance. Equity awards are generally granted in the form of BlackRock, Inc. restricted stock units that, once vested, settle in BlackRock, Inc. common stock.

As of July 31, 2011, the Portfolio Managers did not beneficially own shares of the Fund.

Codes of Ethics. The Trust, BFA and the Distributor have adopted Codes of Ethics pursuant to Rule 17j-1 of the 1940 Act. The Codes of Ethics permit personnel subject to the Codes of Ethics to invest in securities, subject to certain limitations, including securities that may be purchased or held by the Fund. The Codes of Ethics are on public file with, and are available from, the SEC.

Anti-Money Laundering Requirements. The Fund is subject to the USA PATRIOT Act (the “Patriot Act”). The Patriot Act is intended to prevent the use of the U.S. financial system in furtherance of money laundering, terrorism or other illicit activities. Pursuant to requirements under the Patriot Act, the Fund may request information from Authorized Participants to enable it to form a reasonable belief that it knows the true identity of its Authorized Participants. This information will be used to verify the identity of Authorized Participants or, in some cases, the status of financial professionals; it will be used only for compliance with the requirements of the Patriot Act.

The Fund reserves the right to reject purchase orders from persons who have not submitted information sufficient to allow the Fund to verify their identity. The Fund also reserves the right to redeem any amounts in the Fund from persons whose identity it is unable to verify on a timely basis. It is the Fund’s policy to cooperate fully with appropriate regulators in any investigations conducted with respect to potential money laundering, terrorism or other illicit activities.

Administrator, Custodian and Transfer Agent. State Street Bank and Trust Company (“State Street”) serves as administrator, custodian and transfer agent for the Fund under the Master Services Agreement and related Service Schedule (the “Service Module”). State Street’s principal address is 200 Clarendon Street, Boston, MA 02116. Pursuant to the Service Module for Fund Administration and Accounting Services with the Trust, State Street provides necessary administrative, legal, tax and accounting and financial reporting services for the maintenance and operations of the Trust and the Fund. In addition, State Street makes available the office space, equipment, personnel and facilities required to provide such services. Pursuant to the Service Module for Custodial Services with the Trust, State Street maintains, in separate accounts, cash, securities and other assets of the Trust and the Fund, keeps all necessary accounts and records and provides other services. State Street is required, upon the order of the Trust, to deliver securities held by State Street and to make payments for securities purchased by the Trust for the Fund. State Street is authorized to appoint certain foreign custodians or foreign custody managers for Fund investments outside the United States. Pursuant to the Service Module for Transfer Agency

Services with the Trust, State Street acts as a transfer agent for the Fund’s authorized and issued shares of beneficial interest, and as dividend disbursing agent of the Trust. As compensation for these services, State Street receives certain out-of-pocket costs, transaction fees and asset-based fees which are accrued daily and paid monthly by BFA from its management fee.

The following table sets forth the administration, transfer agency and custodian expenses of the Fund paid by BFA to State Street for the fiscal years noted:

Subsidiary Administrator. International Financial Services Limited (“IFS”) serves as the Subsidiary’s Mauritius administrator. Pursuant to an agreement with IFS, the Subsidiary pays a fee for administrative, legal, tax and accounting services to IFS, for certain shareholder services and for providing office space, equipment, personnel and facilities required to provide such services to the Subsidiary.

Distributor. The Distributor’s principal address is One Freedom Valley Drive, Oaks, PA 19456. The Distributor has entered into a Distribution Agreement with the Trust pursuant to which it distributes shares of the Fund. The Distribution Agreement will continue for two years from its effective date and is renewable annually. Shares are continuously offered for sale by the Fund through the Distributor only in Creation Units, as described in the Prospectus and below in the Creation and Redemption of Creation Units section of this SAI. Fund shares in amounts less than Creation Units are not distributed by the Distributor. The Distributor will deliver the Prospectus and, upon request, the SAI to persons purchasing Creation Units and will maintain records of both orders placed with it and confirmations of acceptance furnished by it. The Distributor is a broker-dealer registered under the Securities Exchange Act of 1934, as amended (the “1934 Act”), and a member of the Financial Industry Regulatory Authority, Inc. (“FINRA”).

The Distribution Agreement for the Fund provides that it may be terminated at any time, without the payment of any penalty, on at least 60 days’ prior written notice to the other party following (i) the vote of a majority of the Independent Trustees, or (ii) the vote of a majority of the outstanding voting securities (as defined in the 1940 Act) of the Fund. The Distribution Agreement will terminate automatically in the event of its assignment (as defined in the 1940 Act).

The Distributor may also enter into agreements with securities dealers (“Soliciting Dealers”) who will solicit purchases of Creation Units of Fund shares. Such Soliciting Dealers may also be Authorized Participants (as defined below), Depository Trust Company (“DTC”) participants and/or investor services organizations.

BFA or BTC may, from time to time and from its own resources, pay, defray or absorb costs relating to distribution, including payments out of its own resources to the Distributor, or to otherwise promote the sale of shares.

The following table sets forth the compensation paid by BFA to the Distributor for certain services, not primarily intended to result in the sale of Fund shares, provided to the Fund during the fiscal years noted:

Financial Intermediary Compensation. BFA and/or BTC and/or their respective subsidiaries (“BFA Entities”) pay certain broker-dealers, banks and other financial intermediaries (“Intermediaries”) for certain activities related to the Fund, other iShares funds or exchange-traded products in general (“Payments”). BFA Entities make Payments from their own assets and not from the assets of the Fund. Although a portion of BFA Entities’ revenue comes directly or indirectly in part from fees paid

by the Fund and other iShares funds, Payments do not increase the price paid by investors for the purchase of shares of, or the cost of owning, the Fund or other iShares funds. BFA Entities make Payments for Intermediaries’ participating in activities that are designed to make registered representatives, other professionals and individual investors more knowledgeable about exchange-traded products, including the Fund or for other activities, such as participation in marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems (“Education Costs”). BFA Entities also make Payments to Intermediaries for certain printing, publishing and mailing costs associated with the Fund or materials relating to exchange-traded products in general (“Publishing Costs”). In addition, BFA Entities make Payments to Intermediaries that make shares of the Fund and certain other iShares funds available to their clients, develop new products that feature iShares or otherwise promote the Fund and other iShares funds. Payments of this type are sometimes referred to as revenue-sharing payments.

Payments to an Intermediary may be significant to the Intermediary, and amounts that Intermediaries pay to your salesperson or other investment professional may also be significant for your salesperson or other investment professional. Because an Intermediary may make decisions about which investment options it will recommend or make available to its clients or what services to provide for various products based on payments it receives or is eligible to receive, Payments create conflicts of interest between the Intermediary and its clients and these financial incentives may cause the Intermediary to recommend the Fund and other iShares funds over other investments. The same conflict of interest exists with respect to your salesperson or other investment professional if he or she receives similar payments from his or her Intermediary firm.

As of February 2, 2010, BFA Entities had arrangements to make Payments other than Education Costs or Publishing Costs only to Fidelity Brokerage Services LLC (“FBS”) and Merrill Lynch, Pierce, Fenner & Smith, Inc. (“ML”). Pursuant to BFA Entities’ arrangement with FBS, FBS has agreed to promote iShares funds to FBS’s customers and not to charge certain of its customers any commissions when those customers purchase or sell shares of certain iShares funds online (the “Co-Branded Marketing Program”). BFA Entities have agreed to facilitate the Co-Branded Marketing Program by making payments to FBS during the term of the agreement in a fixed amount. Upon termination of the agreement the BFA Entities will make additional payments to FBS based upon a number of criteria, including the overall success of the Co-Branded Marketing program and the level of services provided by FBS during the wind-down period. Pursuant to BFA Entities’ arrangement with ML, BFA Entities have agreed to reimburse ML for a portion of certain fee waivers that ML may be required to implement with respect to accounts that hold “plan assets” within the meaning of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”), as a consequence of a technical ERISA affiliate relationship between BFA and ML.

Any additions, modifications, or deletions to Intermediaries listed above that have occurred since the date noted above are not included in the list. Further, BFA Entities make Education Costs and Publishing Costs Payments to other Intermediaries that are not listed above. BFA Entities may determine to make Payments based on any number of metrics. For example, BFA Entities may make Payments at year-end or other intervals in a fixed amount, an amount based upon an Intermediary’s services at defined levels or an amount based on the Intermediary’s net sales of one or more iShares funds in a year or other period, any of which arrangements may include an agreed-upon minimum or maximum payment, or any combination of the foregoing. As of the date of this SAI, BFA anticipates that the Payments paid by BFA Entities in connection with the Fund, iShares funds and exchange-traded products in general will be immaterial to BFA Entities in the aggregate for the next year. Please contact your salesperson or other investment professional for more information regarding any Payments his or her Intermediary firm may receive. Any Payments made by the BFA Entities to an Intermediary may create the incentive for an Intermediary to encourage customers to buy shares of iShares funds.

Brokerage Transactions

BFA assumes general supervision over placing orders on behalf of the Fund for the purchase and sale of portfolio securities. In selecting brokers or dealers for any transaction in portfolio securities, BFA’s policy is to make such selection based on factors deemed relevant, including but not limited to, the breadth of the market in the security, the price of the security, the reasonableness of the commission or mark-up or mark-down, if any, execution capability, settlement capability, back office efficiency and the financial condition of the broker or dealer, both for the specific transaction and on a continuing basis. The overall reasonableness of brokerage commissions paid is evaluated by BFA based upon its knowledge of available information as to the general level of commissions paid by other institutional investors for comparable services. Brokers may also be selected because of their ability to handle special or difficult executions, such as may be involved in large block trades, less liquid securities, broad distributions, or other circumstances. BFA does not consider the provision or value of research, products or services a broker or dealer may provide, if any, as a factor in the selection of a broker or dealer or the

determination of the reasonableness of commissions paid in connection with portfolio transactions. The Trust has adopted policies and procedures that prohibit the consideration of sales of the Fund’s shares as a factor in the selection of a broker or a dealer to execute its portfolio transactions.

The table below sets forth the brokerage commissions paid by the Fund for the fiscal years noted. Any differences in brokerage commissions paid by the Fund from year to year are due to increases or decreases in the Fund’s assets over those periods:

Ended July 31, 2009

08/13/08 $1,968,784 $ 56,830 $ 62,207

The Fund did not pay any brokerage commissions to BlackRock, an affiliate of BFA, and a subsidiary of BTC, during the fiscal year ended July 31, 2011.

The Fund’s purchase and sale orders for securities may be combined with those of other investment companies, clients or accounts that BFA or its Affiliates manage or advise and for which they have brokerage placement authority. If purchases or sales of portfolio securities of the Fund and one or more other accounts managed or advised by BFA or its Affiliates are considered at or about the same time, transactions in such securities are allocated among the Fund and the other accounts in a manner deemed equitable to all by BFA and its Affiliates. In some cases, this procedure could have a detrimental effect on the price or volume of the security as far as the Fund is concerned. However, in other cases, it is possible that the ability to participate in volume transactions and to negotiate lower transaction costs will be beneficial to the Fund. BFA and its Affiliates may deal, trade and invest for their own account in the types of securities in which the Fund may invest. BFA and its Affiliates may, from time to time, effect trades on behalf of and for the account of the Fund with brokers or dealers that are affiliated with BFA, in conformity with the 1940 Act and SEC rules and regulations. Under these provisions, any commissions paid to affiliated brokers or dealers must be reasonable and fair compared to the commissions charged by other brokers or dealers in comparable transactions. The Fund will not deal with affiliates in principal transactions unless permitted by applicable SEC rules or regulations, or by SEC exemptive order.

Portfolio turnover may vary from year to year, as well as within a year. High turnover rates may result in comparatively greater brokerage expenses. The table below sets forth the portfolio turnover rates of the Fund for the fiscal years noted:

Fiscal Year ended July 31, 2011 Fiscal Year ended July 31, 2010
41% 3%

Creation or redemption transactions, to the extent consisting of cash, may require the Fund to contemporaneously transact with broker-dealers for purchases of Deposit Securities (as defined below under Fund Deposit) or sales of Fund Securities (as defined below under Redemption of Creation Units), as applicable. Such transactions may be agreed to at guaranteed price levels in order to reduce transaction costs the Fund would otherwise incur as a consequence of settling creation or redemption baskets in cash rather than in-kind.


Following the Fund’s receipt of an order to purchase or redeem creation or redemption baskets, to the extent such purchases or redemptions consist of a cash portion, the Fund will enter an order with a broker or dealer to purchase or sell the Deposit Securities or Fund Securities, as applicable. The terms of such order will typically require the broker or dealer to guarantee that the Fund will achieve execution of its order at a price at least as favorable to the Fund as the Fund’s valuation of the Deposit Securities/Fund Securities used for purposes of calculating the NAV applied to the creation or redemption transaction giving rise to the order (the “Execution Performance Guarantee”). Such orders may be placed with the purchasing or redeeming Authorized Participant in its capacity as a broker-dealer or its affiliated broker-dealer. The amount payable to the Fund in respect of any Execution Performance Guarantee will depend on the results achieved by the executing firm and will vary depending on market activity, timing and a variety of other factors.


To ensure that an Execution Performance Guarantee will be honored on orders arising from creation transactions executed by an Authorized Participant or its affiliate as broker-dealer, an Authorized Participant is required to deposit an amount with the

Fund (the “Execution Performance Deposit”). If the broker-dealer executing the order achieves executions in market transactions at a price equal to or more favorable than the Fund’s valuation of the Deposit Securities, the Fund receives the benefit of the favorable executions and returns to the Authorized Participant the Execution Performance Deposit. If, however, the broker-dealer executing the order is unable to achieve executions in market transactions at a price at least equal to the Fund’s valuation of the securities, the Fund retains the portion of the Execution Performance Deposit equal to the full amount of the execution shortfall (including any taxes, brokerage, commissions or other costs).


To ensure that an Execution Performance Guarantee will be honored for brokerage orders arising from redemption transactions executed by an Authorized Participant or its affiliate as broker-dealer, an Authorized Participant agrees to pay the shortfall amount (the “Execution Performance Offset”). If the broker-dealer executing the order achieves executions in market transactions at a price equal to or more favorable than the Fund’s valuation of the Fund Securities, the Fund receives the benefit of the favorable executions and the Authorized Participant is not called upon to honor the Execution Performance Offset. If, however, the broker-dealer is unable to achieve executions in market transactions at a price at least equal to the Fund’s valuation of the securities, the Fund will be entitled to the portion of the Execution Performance Offset equal to the full amount of the execution shortfall (including any taxes, brokerage, commissions or other costs) and may require the Authorized Participant to deposit any additional amounts required to cover the full amount of the actual Execution Performance Guarantee.


The expected amount of any Execution Performance Deposit or Execution Performance Offset for the Fund will be disclosed in the procedures handbook for Authorized Participants and may change from time to time based on the actual experience of the Fund.

Additional Information Concerning the Trust

Shares. The Trust currently consists of more than 190 separate investment series or portfolios called funds. The Trust issues shares of beneficial interests in each fund with no par value. The Board may designate additional iShares funds.

Each share issued by a fund has a pro rata interest in the assets of that fund. Shares have no preemptive, exchange, subscription or conversion rights and are freely transferable. Each share is entitled to participate equally in dividends and distributions declared by the Board with respect to the relevant fund, and in the net distributable assets of such fund on liquidation.

Each share has one vote with respect to matters upon which the shareholder is entitled to vote. In any matter submitted to shareholders for a vote, each fund shall hold a separate vote, provided that shareholders of all affected funds will vote together when: (1) required by the 1940 Act, or (2) the Trustees determine that the matter affects the interests of more than one fund.

Under Delaware law, the Trust is not required to hold an annual meeting of shareholders unless required to do so under the 1940 Act. The policy of the Trust is not to hold an annual meeting of shareholders unless required to do so under the 1940 Act. All shares (regardless of the fund) have noncumulative voting rights in the election of members of the Board. Under Delaware law, Trustees of the Trust may be removed by vote of the shareholders.

Following the creation of the initial Creation Unit(s) of shares of a fund and immediately prior to the commencement of trading in the fund’s shares, a holder of shares may be a “control person” of the fund, as defined in the 1940 Act. The fund cannot predict the length of time for which one or more shareholders may remain a control person of the fund.

In accordance with the Trust’s Amended and Restated Agreement and Declaration of Trust dated September 17, 2009 (the “Declaration of Trust”), the Board may, without shareholder approval (unless such shareholder approval is required by applicable law, including the 1940 Act), cause one or more funds commencing operations after September 24, 2008 (each, a “New Fund”) to merge, reorganize, consolidate, sell all or substantially all of their assets, or take other similar actions with, to or into another New Fund.

Shareholders may make inquiries by writing to iShares Trust, c/o SEI Investments Distribution Co., One Freedom Valley Drive, Oaks, PA 19456.

Absent an applicable exemption or other relief from the SEC or its staff, beneficial owners of more than 5% of the shares of a fund may be subject to the reporting provisions of Section 13 of the 1934 Act and the SEC’s rules promulgated thereunder. In addition, absent an applicable exemption or other relief from the SEC or its staff, officers and trustees of the fund and

beneficial owners of 10% of the shares of the fund (“Insiders”) may be subject to the insider reporting, short-swing profit and short sale provisions of Section 16 of the 1934 Act and the SEC’s rules promulgated thereunder. Beneficial owners and Insiders should consult with their own legal counsel concerning their obligations under Sections 13 and 16 of the 1934 Act.

Termination of the Trust or the Fund. The Trust or the Fund may be terminated by a majority vote of the Board, subject to the affirmative vote of a majority of the shareholders of the Trust or the Fund entitled to vote on termination; however, in certain circumstances described in the Declaration of Trust, only a majority vote of the Board is required. Although the shares are not automatically redeemable upon the occurrence of any specific event, the Declaration of Trust provide that the Board will have the unrestricted power to alter the number of shares in a Creation Unit. In the event of a termination of the Trust or the Fund, the Board, in its sole discretion, could determine to permit the shares to be redeemable in aggregations smaller than Creation Units or to be individually redeemable. In such circumstance, the Trust may make redemptions in-kind, for cash or for a combination of cash or securities.

DTC as Securities Depository for Shares of the Fund. Shares of the Fund are represented by securities registered in the name of DTC or its nominee and deposited with, or on behalf of, DTC.

DTC, a limited-purpose trust company, was created to hold securities of its participants (“DTC Participants”) and to facilitate the clearance and settlement of securities transactions among the DTC Participants in such securities through electronic book-entry changes in accounts of the DTC Participants, thereby eliminating the need for physical movement of securities’ certificates. DTC Participants include securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations, some of whom (and/or their representatives) own DTC. More specifically, DTC is owned by a number of its DTC Participants and by the New York Stock Exchange (“NYSE”), the NYSE Amex Equities and FINRA. Access to the DTC system is also available to others such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a DTC Participant, either directly or indirectly (“Indirect Participants”).

Beneficial ownership of shares is limited to DTC Participants, Indirect Participants and persons holding interests through DTC Participants and Indirect Participants. Ownership of beneficial interests in shares (owners of such beneficial interests are referred to herein as “Beneficial Owners”) is shown on, and the transfer of ownership is effected only through, records maintained by DTC (with respect to DTC Participants) and on the records of DTC Participants (with respect to Indirect Participants and Beneficial Owners that are not DTC Participants). Beneficial Owners will receive from or through the DTC Participant a written confirmation relating to their purchase of shares. The laws of some jurisdictions may require that certain purchasers of securities take physical delivery of such securities in definitive form. Such laws may impair the ability of certain investors to acquire beneficial interests in shares.

Conveyance of all notices, statements and other communications to Beneficial Owners is effected as follows. Pursuant to the Depositary Agreement between the Trust and DTC, DTC is required to make available to the Trust upon request and for a fee to be charged to the Trust a listing of the shares of the Fund held by each DTC Participant. The Trust shall inquire of each such DTC Participant as to the number of Beneficial Owners holding shares, directly or indirectly, through such DTC Participant. The Trust shall provide each such DTC Participant with copies of such notice, statement or other communication, in such form, number and at such place as such DTC Participant may reasonably request, in order that such notice, statement or communication may be transmitted by such DTC Participant, directly or indirectly, to such Beneficial Owners. In addition, the Trust shall pay to each such DTC Participant a fair and reasonable amount as reimbursement for the expenses attendant to such transmittal, all subject to applicable statutory and regulatory requirements.

Share distributions shall be made to DTC or its nominee, Cede & Co., as the registered holder of all shares of the Trust. DTC or its nominee, upon receipt of any such distributions, shall credit immediately DTC Participants’ accounts with payments in amounts proportionate to their respective beneficial interests in shares of the Fund as shown on the records of DTC or its nominee. Payments by DTC Participants to Indirect Participants and Beneficial Owners of shares held through such DTC Participants will be governed by standing instructions and customary practices, as is now the case with securities held for the accounts of customers in bearer form or registered in a “street name,” and will be the responsibility of such DTC Participants.

The Trust has no responsibility or liability for any aspect of the records relating to or notices to Beneficial Owners, or payments made on account of beneficial ownership interests in such shares, or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests, or for any other aspect of the relationship between DTC and the DTC Participants or the relationship between such DTC Participants and the Indirect Participants and Beneficial Owners owning through such DTC Participants. DTC may decide to discontinue providing its service with respect to shares of the Trust at any

time by giving reasonable notice to the Trust and discharging its responsibilities with respect thereto under applicable law. Under such circumstances, the Trust shall take action to find a replacement for DTC to perform its functions at a comparable cost.

Creation and Redemption of Creation Units

General. The Trust issues and sells shares of the Fund only in Creation Units on a continuous basis through the Distributor, without a sales load, at a price based on the Fund’s NAV next determined after receipt, on any Business Day (as defined below), of an order in proper form. The following table sets forth the number of shares of the Fund that constitute a Creation Unit for the Fund and the value of such Creation Unit as of September 30, 2011:

Shares Per
Creation Unit
Value Per
Creation
Unit (U.S.$)
100,000 $4,861,000

The Board reserves the right to declare a split or a consolidation in the number of shares outstanding of the Fund, and to make a corresponding change in the number of shares constituting a Creation Unit, in the event that the per share price in the secondary market rises (or declines) to an amount that falls outside the range deemed desirable by the Board.

A “Business Day” with respect to the Fund is any day on which the Listing Exchange on which the Fund is listed for trading is open for business. As of the date of this SAI, the Listing Exchange observes the following holidays, as observed: New Year’s Day, Martin Luther King, Jr. Day, Presidents’ Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day.

Fund Deposit. The consideration for purchase of Creation Units of the Fund generally consists of the in-kind deposit of a designated portfolio of securities (including any portion of such securities for which cash may be substituted) (i.e., the Deposit Securities) and the Cash Component computed as described below. Together, the Deposit Securities and the Cash Component constitute the “Fund Deposit,” which when combined with the Fund’s portfolio securities is designed to generate performance that has a collective investment profile similar to that of the Underlying Index. The Fund Deposit represents the minimum initial and subsequent investment amount for a Creation Unit of the Fund.

The Cash Component is an amount equal to the difference between the net asset value of the shares (per Creation Unit) and the “Deposit Amount,” which is an amount equal to the market value of the Deposit Securities, and serves to compensate for any differences between the net asset value per Creation Unit and the Deposit Amount. Payment of any stamp duty or other similar fees and expenses payable upon transfer of beneficial ownership of the Deposit Securities are the sole responsibility of the Authorized Participant purchasing the Creation Unit. The Fund currently offers Creation Units partially for cash.

BFA makes available through the NSCC on each Business Day, prior to the opening of business on the Listing Exchange, the list of names and the required number of shares of each Deposit Security and the amount of the Cash Component to be included in the current Fund Deposit (based on information as of the end of the previous Business Day) for the Fund. Such Fund Deposit is applicable, subject to any adjustments as described below, in order to effect purchases of Creation Units of shares of the Fund until such time as the next-announced Fund Deposit is made available.

The identity and number of shares of the Deposit Securities change pursuant to changes in the composition of the Fund’s portfolio and as rebalancing adjustments and corporate action events are reflected from time to time by BFA with a view to the investment objective of the Fund. The composition of the Deposit Securities may also change in response to adjustments to the weighting or composition of the component securities constituting the Underlying Index.

The Fund reserves the right to permit or require the substitution of a “cash in lieu” amount to be added to the Cash Component to replace any Deposit Security that may not be available in sufficient quantity for delivery or that may not be eligible for transfer through DTC. The Fund also reserves the right to permit or require a “cash in lieu” amount in certain circumstances, including circumstances in which (i) the delivery of the Deposit Security by the Authorized Participant (as described below) would be restricted under applicable securities laws or (ii) the delivery of the Deposit Security to the Authorized Participant would result in the disposition of the Deposit Security by the Authorized Participant becoming restricted under applicable securities laws, or in certain other situations.

Role of the Authorized Participant. Creation Units may be purchased only by or through a DTC Participant that has entered into an Authorized Participant Agreement with the Distributor (an “Authorized Participant”). Such Authorized Participant will agree, pursuant to the terms of such Authorized Participant Agreement and on behalf of itself or any investor on whose behalf it will act, to certain conditions, including that such Authorized Participant will make available in advance of each purchase of shares an amount of cash sufficient to pay the Cash Component, once the net asset value of a Creation Unit is next determined after receipt of the purchase order in proper form, together with the transaction fee described below. The Authorized Participant may require the investor to enter into an agreement with such Authorized Participant with respect to certain matters, including payment of the Cash Component. Investors who are not Authorized Participants must make appropriate arrangements with an Authorized Participant. Investors should be aware that their particular broker may not be a DTC Participant or may not have executed an Authorized Participant Agreement and that orders to purchase Creation Units may have to be placed by the investor’s broker through an Authorized Participant. As a result, purchase orders placed through an Authorized Participant may result in additional charges to such investor. The Trust does not expect to enter into an Authorized Participant Agreement with more than a small number of DTC Participants. A list of current Authorized Participants may be obtained from the Distributor.

Purchase Orders. To initiate an order for a Creation Unit, an Authorized Participant must submit to the Distributor an irrevocable order to purchase shares of the Fund generally before 4:00 p.m., Eastern time on any Business Day to receive that day’s NAV. On days when the Listing Exchange closes earlier than normal, the Fund may require orders for Creation Units to be placed earlier in the day. The Distributor will notify BFA and the Custodian of such order. The Custodian will then provide such information to any appropriate subcustodian. Procedures and requirements governing the delivery of the Fund Deposit are set forth in the procedure handbook for Authorized Participants and may change from time to time. Those placing orders to purchase Creation Units through an Authorized Participant should allow sufficient time to permit proper submission of the purchase order to the Distributor by the Cutoff Time (as defined below) on such Business Day.

The Authorized Participant must also make available on or before the contractual settlement date, by means satisfactory to the Fund, immediately available or same day funds estimated by the Fund to be sufficient to pay the Cash Component next determined after acceptance of the purchase order, together with the applicable purchase transaction fees. Any excess funds will be returned following settlement of the issue of the Creation Unit. Those placing orders should ascertain the deadline for cash transfers by contacting the operations department of the broker or depositary institution effectuating the transfer of the Cash Component. This deadline is likely to be significantly earlier than the Cutoff Time (as described below) of the Fund.

The Authorized Participant is responsible for any and all expenses and costs incurred by the Fund, including any applicable cash amounts, in connection with any purchase order.

Investors, other than Authorized Participants, are responsible for making arrangements for a creation request to be made through an Authorized Participant. The Distributor will provide a list of current Authorized Participants upon request. Investors should be aware that an Authorized Participant may require orders for purchases of shares placed with it to be in the particular form required by the individual Authorized Participant.

Timing of Submission of Purchase Orders. An Authorized Participant must submit an irrevocable order to purchase shares of a Fund generally before 4:00 p.m., Eastern time on any Business Day in order to receive that day’s NAV. Orders to create shares of the Fund that are submitted on the Business Day immediately preceding a holiday or day (other than a weekend) when the equity markets in the relevant foreign market are closed may not be accepted. The deadline specified above for the submission of purchase orders is referred to as the Fund’s “Cutoff Time.” The Distributor in its discretion may permit the submission of such orders and requests by or through an Authorized Participant at any time (including on days on which the Listing Exchange is not open for business) via communication through the facilities of the Distributor’s proprietary website maintained for this purpose. Purchase orders and redemption requests, if accepted by the Trust, will be processed based on the NAV next determined after such acceptance in accordance with the Trust’s standard Cutoff Times as provided in the Authorized Participant Agreement and disclosed in this SAI.

Acceptance of Orders for Creation Units. Subject to the conditions that (i) an irrevocable purchase order has been submitted by the Authorized Participant (either on its own or another investor’s behalf) and (ii) arrangements satisfactory to the Fund are in place for payment of the Cash Component and any other cash amounts which may be due, the Fund will accept the order, subject to the Fund’s right (and the right of the Distributor and BFA) to reject any order until acceptance.

Once the Fund has accepted an order, upon the next determination of the net asset value of the shares, the Fund will confirm the issuance of a Creation Unit, against receipt of payment, at such net asset value. The Distributor will then transmit a confirmation of acceptance to the Authorized Participant that placed the order.

The Fund reserves the absolute right to reject or revoke a creation order transmitted to it by the Distributor if (i) the order is not in proper form; (ii) the investor(s), upon obtaining the shares ordered, would own 80% or more of the currently outstanding shares of the Fund; (iii) the Deposit Securities delivered do not conform to the identity and number of shares specified, as described above; (iv) acceptance of the Deposit Securities would have certain adverse tax consequences to the Fund; (v) acceptance of the Fund Deposit would, in the opinion of counsel, be unlawful; (vi) acceptance of the Fund Deposit would, in the discretion of the Fund or BFA, have an adverse effect on the Fund or the rights of beneficial owners; or (vii) circumstances outside the control of the Fund, the Distributor and BFA make it impracticable to process purchase orders. The Distributor shall notify a prospective purchaser of a Creation Unit and/or the Authorized Participant acting on behalf of such purchaser of its rejection of such order. The Fund, State Street, the subcustodian and the Distributor are under no duty, however, to give notification of any defects or irregularities in the delivery of Portfolio Deposits nor shall any of them incur any liability for failure to give such notification.

In addition, the Trust intends to exercise its right to reject any creation order for shares of the Fund on any Business Day that is a holiday in the Indian market that is not a holiday observed in the U.S. equity market and certain other holidays during the settlement cycle for Fund shares in order to protect Fund shareholders from any dilutive costs that may be associated with the purchase of Deposit Securities in connection with creation orders on such days.

Issuance of a Creation Unit. Except as provided herein, a Creation Unit will not be issued until the transfer of good title to the Fund of the Deposit Securities and the payment of the Cash Component have been completed. When the subcustodian has confirmed to the Custodian that the securities included in the Fund Deposit (or the cash value thereof) have been delivered to the account of the relevant subcustodian or subcustodians, the Distributor and BFA shall be notified of such delivery and the Fund will issue and cause the delivery of the Creation Unit. Creation Units typically are issued on a “T+3 basis” (i.e., three Business Days after trade date). However, as discussed in the Regular Holidays section, the Fund reserves the right to settle Creation Unit transactions on a basis other than T+3 in order to accommodate non-U.S. market holiday schedules, to account for different treatment among non-U.S. and U.S. markets of dividend record dates and ex-dividend dates (i.e., the last day the holder of a security can sell the security and still receive dividends payable on the security) and in certain other circumstances.

To the extent contemplated by an Authorized Participant’s agreement with the Distributor, the Fund will issue Creation Units to such Authorized Participant, notwithstanding the fact that the corresponding Portfolio Deposits have not been received in part or in whole, in reliance on the undertaking of the Authorized Participant to deliver the missing Deposit Securities as soon as possible, which undertaking shall be secured by such Authorized Participant’s delivery and maintenance of collateral having a value at least equal to 105% and up to 115%, which percentage BFA may change from time to time, of the value of the missing Deposit Securities in accordance with the Fund’s then-effective procedures. The only collateral that is acceptable to the Fund is cash in U.S. dollars. Such cash collateral must be delivered no later than 2:00 p.m., Eastern time on the contractual settlement date. The cash collateral posted by the Authorized Participant may be invested at the risk of the Authorized Participant, and income, if any, on invested cash collateral will be paid to that Authorized Participant. Information concerning the Fund’s current procedures for collateralization of missing Deposit Securities is available from the Distributor. The Authorized Participant Agreement will permit the Fund to buy the missing Deposit Securities at any time and will subject the Authorized Participant to liability for any shortfall between the cost to the Fund of purchasing such securities and the cash collateral.

In certain cases, Authorized Participants may create and redeem Creation Units on the same trade date and in these instances, the Fund reserves the right to settle these transactions on a net basis or require a representation from the Authorized Participants that the creation and redemption transactions are for separate beneficial owners. All questions as to the number of shares of each security in the Deposit Securities and the validity, form, eligibility and acceptance for deposit of any securities to be delivered shall be determined by the Fund and the Fund’s determination shall be final and binding.

Cash Purchase Method. Creation Units of the Fund are currently offered partially for cash. Purchases of Creation Units for cash are effected in essentially the same manner as in-kind purchases. In the case of a cash purchase, the Authorized Participant must pay the cash equivalent of the Deposit Securities it would otherwise be required to provide through an in-kind purchase, plus the same Cash Component required to be paid by an in-kind purchaser. In addition, the Authorized Participant will be required to pay certain transaction fees and charges for cash purchases as described below.

Costs Associated with Creation Transactions. A standard creation transaction fee is imposed to offset the transfer and other transaction costs associated with the issuance of Creation Units. The standard creation transaction fee will be the same regardless of the number of Creation Units purchased by an Authorized Participant on the applicable Business Day. If a purchase consists of a cash portion, the Authorized Participant may also be required to cover certain brokerage, tax, foreign exchange, execution, market impact and other costs and expenses related to the execution of trades resulting from the cash portion of such transaction, as further described in the Brokerage Transactions section of this SAI. The Authorized Participants may also be required to pay an additional charge (up to the maximum amount shown below) to cover costs related to the creation transaction. Authorized Participants will also bear the costs of transferring the Deposit Securities to the Fund. Investors who use the services of a broker or other financial intermediary may be charged a fee for such services.

The following table sets forth the Fund’s standard creation transaction fees and maximum additional charge (as described above):

Standard Creation
Transaction Fee
Maximum Additional
Charge for
Creations*
$4,500 3.0%

* As a percentage of the net asset value per Creation Unit.
Redemption of Creation Units. Shares of the Fund may be redeemed by Authorized Participants only in Creation Units at their NAV next determined after receipt of a redemption request in proper form by the Distributor and only on a Business Day. The Fund will not redeem shares in amounts less than Creation Units. There can be no assurance, however, that there will be sufficient liquidity in the secondary market at any time to permit assembly of a Creation Unit. Investors should expect to incur brokerage and other costs in connection with assembling a sufficient number of shares to constitute a Creation Unit that could be redeemed by an Authorized Participant. Beneficial owners also may sell shares in the secondary market.

BFA makes available through the NSCC, prior to the opening of business on the Listing Exchange on each Business Day, the designated portfolio of securities (including any portion of such securities for which cash may be substituted) that will be applicable (subject to possible amendment or correction) to redemption requests received in proper form (as defined below) on that day (“Fund Securities”), and an amount of cash (as described below). Such Fund Securities and the corresponding cash amount are applicable, subject to any adjustments as described below, in order to effect redemptions of Creation Units of the Fund until such time as the next announced composition of the Fund Securities is made available. Fund Securities received on redemption may not be identical to Deposit Securities that are applicable to creations of Creation Units.

Unless cash redemptions are available or specified for the Fund, the redemption proceeds for a Creation Unit generally consist of Fund Securities, plus additional cash in an amount equal to the difference between the net asset value of the shares being redeemed, as next determined after the receipt of a request in proper form, and the value of Fund Securities, less a redemption transaction fee (as described below). The Trust may, in its sole discretion, substitute a “cash in lieu” amount to replace any Fund Security. The amount of cash paid out in such cases will be equivalent to the value of the substituted security listed as a Fund Security. In the event that the Fund Securities have a value greater than the NAV of the shares, a compensating cash payment equal to the difference is required to be made by or through an Authorized Participant by the redeeming shareholder. The Fund currently redeems shares generally for partial cash.

Costs Associated with Redemption Transactions. A redemption transaction fee is imposed to offset transfer and other transaction costs that may be incurred by the Fund. The standard redemption transaction fee will be the same regardless of the number of Creation Units redeemed by an Authorized Participant on the applicable Business Day. If a redemption consists

of a cash portion, the Authorized Participant may also be required to cover certain brokerage, tax, foreign exchange, execution, market impact and other costs and expenses related to the execution of trades resulting from the cash portion of such transaction, as further described in the Brokerage Transactions section of this SAI. The Authorized Participants may also be required to pay an additional charge (up to the maximum amount shown below) to cover other costs related to the redemption transaction. Authorized Participants will also bear the costs of transferring the Fund Securities from the Fund to their account on their order. Investors who use the services of a broker or other financial intermediary may be charged a fee for such services.

The following table sets forth the Fund’s standard redemption transaction fees and maximum additional charge (as described above):

Standard Redemption
Transaction Fee
Maximum Additional
Charge for
Redemptions*
$4,500 2.0%

* As a percentage of the net asset value per Creation Unit, inclusive of the standard redemption transaction fee.

Placement of Redemption Orders. Redemption requests for Creation Units of the Fund must be submitted to the Distributor by or through an Authorized Participant. An Authorized Participant must submit an irrevocable request to redeem shares of a Fund generally before 4:00 p.m., Eastern time on any Business Day, in order to receive that day’s NAV. Orders to redeem shares of each Fund that are submitted on the Business Day immediately preceding a holiday or day (other than a weekend) when the equity markets in the relevant foreign market are closed may not be accepted. Investors other than Authorized Participants are responsible for making arrangements for a redemption request to be made through an Authorized Participant. The Distributor will provide a list of current Authorized Participants upon request.

The Authorized Participant must transmit the request for redemption in the form required by the Fund to the Distributor in accordance with procedures set forth in the Authorized Participant Agreement. Investors should be aware that their particular broker may not have executed an Authorized Participant Agreement and that, therefore, requests to redeem Creation Units may have to be placed by the investor’s broker through an Authorized Participant who has executed an Authorized Participant Agreement. At any time, only a limited number of broker-dealers will have an Authorized Participant Agreement in effect. Investors making a redemption request should be aware that such request must be in the form specified by such Authorized Participant. Investors making a request to redeem Creation Units should allow sufficient time to permit proper submission of the request by an Authorized Participant and transfer of the shares to the Fund’s Transfer Agent; such investors should allow for the additional time that may be required to effect redemptions through their banks, brokers or other financial intermediaries if such intermediaries are not Authorized Participants.

A redemption request is considered to be in “proper form” if (i) an Authorized Participant has transferred or caused to be transferred to the Fund’s Transfer Agent the Creation Unit being redeemed through the book-entry system of DTC so as to be effective by the Listing Exchange closing time on any Business Day, (ii) a request in form satisfactory to the Fund is received by the Distributor from the Authorized Participant on behalf of itself or another redeeming investor within the time periods specified above and (iii) all other procedures set forth in the Authorized Participant Agreement are properly followed. If the Transfer Agent does not receive the investor’s shares through DTC’s facilities by 10:00 a.m., Eastern time on the Business Day next following the day that the redemption request is received, the redemption request shall be rejected. Investors should be aware that the deadline for such transfers of shares through the DTC system may be significantly earlier than the close of business on the Listing Exchange. Those making redemption requests should ascertain the deadline applicable to transfers of shares through the DTC system by contacting the operations department of the broker or depositary institution effecting the transfer of the shares.

Upon receiving a redemption request, the Distributor shall notify the Fund and the Fund’s Transfer Agent of such redemption request. The tender of an investor’s shares for redemption and the distribution of the securities and/or cash redemption included in the payment made in respect of Creation Units redeemed will be made through DTC and the relevant Authorized Participant to the Beneficial Owner thereof as recorded on the book-entry system of DTC or the DTC Participant through which such investor holds, as the case may be, or by such other means specified by the Authorized Participant submitting the redemption request.

A redeeming Beneficial Owner or Authorized Participant acting on behalf of such Beneficial Owner must maintain appropriate security arrangements with a qualified broker-dealer, bank or other custody providers in each jurisdiction in which any of the Portfolio Securities are customarily traded, to which account such Portfolio Securities will be delivered.

Deliveries of redemption proceeds by the Fund generally will be made within three Business Days (i.e., “T+3”). However, as discussed in the Regular Holidays section, the Fund reserves the right to settle redemption transactions and deliver redemption proceeds on another basis to accommodate non-U.S. market holiday schedules, to account for different treatment among non-U.S. and U.S. markets of dividend record dates and dividend ex-dates (i.e., the last date the holder of a security can sell the security and still receive dividends payable on the security sold) and in certain other circumstances. The Regular Holidays section hereto identifies the instances, if any, where more than seven days would be needed to deliver redemption proceeds. Pursuant to an order of the SEC, the Trust will make delivery of redemption proceeds within the number of days stated in the Regular Holidays section to be the maximum number of days necessary to deliver redemption proceeds.


If neither the redeeming Beneficial Owner nor the Authorized Participant acting on behalf of such redeeming Beneficial Owner has appropriate arrangements to take delivery of Fund Securities in the applicable non-U.S. jurisdiction and it is not possible to make other such arrangements, or if it is not possible to effect deliveries of Fund Securities in such jurisdiction, the Trust may in its discretion exercise its option to redeem such shares in cash, and the redeeming Beneficial Owner will be required to receive its redemption proceeds in cash. In such case, the investor will receive a cash payment equal to the net asset value of its shares based on the NAV of the Fund next determined after the redemption request is received in proper form (minus a redemption transaction fee and additional charges specified above to offset the Trust’s brokerage and other transaction costs associated with the disposition of Fund Securities). Redemptions of shares for Fund Securities will be subject to compliance with applicable U.S. federal and state securities laws and the Fund (whether or not it otherwise permits cash redemptions) reserves the right to redeem Creation Units for cash to the extent that the Fund cannot lawfully deliver specific Fund Securities upon redemptions or cannot do so without first registering the Fund Securities under such laws.


Although the Trust does not ordinarily permit cash redemptions of Creation Units, in the event that cash redemptions are permitted or required by the Trust, proceeds will be paid to the Authorized Participant redeeming shares as soon as practicable after the date of redemption (within seven calendar days thereafter, except for the instances listed in the Regular Holidays section in which more than seven calendar days would be needed).

To the extent contemplated by an Authorized Participant’s agreement with the Distributor, in the event an Authorized Participant has submitted a redemption request in proper form but is unable to transfer all or part of the Creation Unit to be redeemed to the Fund, at or prior to 10:00 a.m., Eastern time on the Listing Exchange business day after the date of submission of such redemption request, the Distributor will accept the redemption request in reliance on the undertaking by the Authorized Participant to deliver the missing shares as soon as possible. Such undertaking shall be secured by the Authorized Participant’s delivery and maintenance of collateral consisting of cash, in U.S. dollars in immediately available funds, having a value at least equal to 105% and up to 115%, which percentage BFA may change from time to time, of the value of the missing shares. Such cash collateral must be delivered no later than 10:00 a.m., Eastern time on the day after the date of submission of such redemption request and shall be held by State Street and marked-to-market daily. The fees of State Street and any subcustodians in respect of the delivery, maintenance and redelivery of the cash collateral shall be payable by the Authorized Participant. The cash collateral posted by the Authorized Participant may be invested at the risk of the Authorized Participant, and income, if any, on invested cash collateral will be paid to that Authorized Participant. The Authorized Participant Agreement permits the Fund to acquire Fund Securities and the Cash Component underlying such shares at any time and subjects the Authorized Participant to liability for any shortfall between the cost to the Fund of purchasing such shares, Fund Securities or Cash Component and the value of the cash collateral.

Because the Portfolio Securities of the Fund may trade on exchange(s) on days that the Listing Exchange is closed or are otherwise not Business Days for the Fund, shareholders may not be able to redeem their shares of the Fund, or purchase or sell shares of the Fund on the Listing Exchange on days when the NAV of the Fund could be significantly affected by events in the relevant non-U.S. markets.

The right of redemption may be suspended or the date of payment postponed with respect to the Fund (i) for any period during which the Listing Exchange is closed (other than customary weekend and holiday closings), (ii) for any period during which trading on the Listing Exchange is suspended or restricted, (iii) for any period during which an emergency exists as a

result of which disposal of the shares of the Fund’s portfolio securities or determination of its net asset value is not reasonably practicable; or (iv) in such other circumstance as is permitted by the SEC.

Taxation on Creation and Redemptions of Creation Units. An Authorized Participant generally will recognize either gain or loss upon the exchange of Deposit Securities for Creation Units. This gain or loss is calculated by taking the market value of the Creation Units purchased over the Authorized Participant’s aggregate basis in the Deposit Securities exchanged therefor. However, the U.S. Internal Revenue Service (the “IRS”) may apply the wash sales rules to determine that any loss realized upon the exchange of Deposit Securities for Creation Units is not currently deductible. Authorized Participants should consult their own tax advisors.

Current U.S. federal tax laws dictate that capital gain or loss realized from the redemption of Creation Units will generally create long-term capital gain or loss if the Authorized Participant holds the Creation Units for more than one year, or short-term capital gain or loss if the Creation Units were held for one year or less, if the Creation Units are held as capital assets.

Regular Holidays. For every occurrence of one or more intervening holidays in the applicable non-U.S. market that are not holidays observed in the U.S. equity market, the redemption settlement cycle will be extended by the number of such intervening holidays. In addition to holidays, other unforeseeable closings in a non-U.S. market due to emergencies may also prevent the Trust from delivering securities within normal settlement period.

The securities delivery cycles currently practicable for transferring portfolio securities to redeeming investors, coupled with non-U.S. market holiday schedules, will require a delivery process longer than seven calendar days, in certain circumstances. The holidays applicable to the Fund during such periods are listed below, as are instances where more than seven days will be needed to deliver redemption proceeds. Although certain holidays may occur on different dates in subsequent years, the number of days required to deliver redemption proceeds in any given year is not expected to exceed the maximum number of days listed below for the Fund. The proclamation of new holidays, the treatment by market participants of certain days as “informal holidays” (e.g., days on which no or limited securities transactions occur, as a result of substantially shortened trading hours), the elimination of existing holidays, or changes in local securities delivery practices, could affect the information set forth herein at some time in the future.

In calendar years 2011 and 2012, the dates of regular holidays affecting the relevant securities markets in which the Fund invests are as follows (please note these holiday schedules are subject to potential changes in the relevant securities markets):

*These worst-case redemption cycles are based on information regarding regular holidays, which may be out of date. Based on changes in holidays, longer (worse) redemption cycles are possible.

Taxes

Regulated Investment Company Qualifications. The Fund intends to qualify for treatment as a separate RIC under Subchapter M of the Internal Revenue Code. To qualify for treatment as a RIC, the Fund must annually distribute at least 90% of its investment company taxable income (which includes dividends, interest and net short-term capital gains) and meet several other requirements. Among such other requirements are the following: (i) at least 90% of the Fund’s annual gross income must be derived from dividends, interest, payments with respect to securities loans, gains from the sale or other disposition of stock or securities or non-U.S. currencies, other income (including, but not limited to, gains from options, futures or forward contracts) derived with respect to its business of investing in such stock, securities or currencies, and net income derived from interests in qualified publicly-traded partnerships (i.e., partnerships that are traded on an established securities market or tradable on a secondary market, other than partnerships that derive 90% of their income from interest, dividends, capital gains and other traditionally permitted mutual fund income); and (ii) at the close of each quarter of the Fund’s taxable year, (a) at least 50% of the market value of the Fund’s total assets must be represented by cash and cash items, U.S. government securities, securities of other RICs and other securities, with such other securities limited for purposes of this calculation in respect of any one issuer to an amount not greater than 5% of the value of the Fund’s assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of the Fund’s

total assets may be invested in the securities (other than U.S. government securities or the securities of other RICs) of any one issuer, of two or more issuers of which 20% or more of the voting stock is held by the Fund and that are engaged in the same or similar trades or businesses or related trades or businesses, or the securities of one or more qualified publicly-traded partnerships.

Although, in general, the passive loss rules of the Internal Revenue Code do not apply to RICs, such rules do apply to a RIC with respect to items attributable to interests in qualified publicly-traded partnerships. The Fund’s investments in partnerships, including in qualified publicly-traded partnerships, may result in the Fund being subject to state, local, or non-U.S. income, franchise or withholding tax liabilities.

Taxation of RICs. As a RIC, the Fund will not be subject to U.S. federal income tax on the portion of its taxable investment income and capital gains that it distributes to its shareholders, provided that it satisfies a minimum distribution requirement. To satisfy the minimum distribution requirement, the Fund must distribute to its shareholders at least the sum of (i) 90% of its “investment company taxable income” (i.e., income other than its net realized long-term capital gain over its net realized short-term capital loss), plus or minus certain adjustments, and (ii) 90% of its net tax-exempt income for the taxable year. The Fund will be subject to income tax at regular corporate rates on any taxable income or gains that it does not distribute to its shareholders. If the Fund fails to qualify for any taxable year as a RIC or fails to meet the distribution requirement, all of its taxable income will be subject to tax at regular corporate income tax rates without any deduction for distributions to shareholders, and such distributions generally will be taxable to shareholders as ordinary dividends to the extent of the Fund’s current and accumulated earnings and profits. In such event, distributions to individuals should be eligible to be treated as qualified dividend income and distributions to corporate shareholders generally should be eligible for the dividends received deduction. Although the Fund intends to distribute substantially all of its net investment income and its capital gains for each taxable year, the Fund will be subject to U.S. federal income taxation to the extent any such income or gains are not distributed. If the Fund fails to qualify as a RIC in any year, it must pay out its earnings and profits accumulated in that year in order to qualify again as a RIC. If the Fund fails to qualify as a RIC for a period greater than two taxable years, the Fund may be required to recognize any net built-in gains with respect to certain of its assets (i.e., the excess of the aggregate gains, including items of income, over aggregate losses that would have been realized with respect to such assets if the Fund had been liquidated) if it qualifies as a RIC in a subsequent year.

Excise Tax. The Fund will be subject to a 4% excise tax on certain undistributed income if it does not distribute to its shareholders in each calendar year at least 98% of its ordinary income for the calendar year plus 98.2% of its capital gain net income for the 12 months ended October 31 of such year. For this purpose, however, any ordinary income or capital gain net income retained by the Fund that is subject to corporate income tax will be considered to have been distributed by year-end. In addition, the minimum amounts that must be distributed in any year to avoid the excise tax will be increased or decreased to reflect any underdistribution or overdistribution, as the case may be, from the previous year. The Fund intends to declare and distribute dividends and distributions in the amounts and at the times necessary to avoid the application of this 4% excise tax.

Net Capital Loss Carryforwards. Net capital loss carryforwards may be applied against any net realized capital gains in each succeeding year, until they have been reduced to zero or until their respective expiration dates, whichever occurs first. Capital loss carryforwards from taxable years beginning after December 2010 are not subject to expiration.

The Fund had tax basis net capital loss carryforwards as of July 31, 2011, the tax year-end for the Fund:

Taxation of U.S. Shareholders. Dividends and other distributions by the Fund are generally treated under the Internal Revenue Code as received by the shareholders at the time the dividend or distribution is made. However, any dividend or distribution declared by the Fund in October, November or December of any calendar year and payable to shareholders of record on a specified date in such a month shall be deemed to have been received by each shareholder on December 31 of such calendar year and to have been paid by the Fund not later than such December 31, provided such dividend is actually paid by the Fund during January of the following calendar year.

The Fund intends to distribute annually to its shareholders substantially all of its investment company taxable income and any net realized long-term capital gains in excess of net realized short-term capital losses (including any capital loss carryovers). However, if the Fund retains for investment an amount equal to all or a portion of its net long-term capital gains in excess of its net short-term capital losses (including any capital loss carryovers), it will be subject to a corporate tax (currently at a maximum rate of 35%) on the amount retained. In that event, the Fund will designate such retained amounts as undistributed capital gains in a notice to its shareholders who (a) will be required to include in income for U.S. federal income tax purposes, as long-term capital gains, their proportionate shares of the undistributed amount, (b) will be entitled to credit their proportionate shares of the 35% tax paid by the Fund on the undistributed amount against their U.S. federal income tax liabilities, if any, and to claim refunds to the extent their credits exceed their liabilities, if any, and (c) will be entitled to increase their tax basis, for U.S. federal income tax purposes, in their shares by an amount equal to 65% of the amount of undistributed capital gains included in the shareholder’s income. Organizations or persons not subject to U.S. federal income tax on such capital gains will be entitled to a refund of their pro rata share of such taxes paid by the Fund upon filing appropriate returns or claims for refund with the IRS.

Distributions of net realized long-term capital gains, if any, that the Fund reports as capital gains dividends are taxable as long-term capital gains, whether paid in cash or in shares and regardless of how long a shareholder has held shares of the Fund. All other dividends of the Fund (including dividends from short-term capital gains) from its current and accumulated earnings and profits (“regular dividends”) are generally subject to tax as ordinary income, subject to the discussion of qualified dividend income below.

If an individual receives a regular dividend qualifying for the long-term capital gains rates and such dividend constitutes an “extraordinary dividend,” and the individual subsequently recognizes a loss on the sale or exchange of stock in respect of which the extraordinary dividend was paid, then the loss will be long-term capital loss to the extent of such extraordinary dividend. An “extraordinary dividend” on common stock for this purpose is generally a dividend (i) in an amount greater than or equal to 10% of the taxpayer’s tax basis (or trading value) in a share of stock, aggregating dividends with ex-dividend dates within an 85-day period, or (ii) in an amount greater than 20% of the taxpayer’s tax basis (or trading value) in a share of stock, aggregating dividends with ex-dividend dates within a 365-day period.

Distributions in excess of the Fund’s current and accumulated earnings and profits will, as to each shareholder, be treated as a tax-free return of capital to the extent of a shareholder’s basis in shares of the Fund, and as a capital gain thereafter (if the shareholder holds shares of the Fund as capital assets). Shareholders receiving dividends or distributions in the form of additional shares should be treated for U.S. federal income tax purposes as receiving a distribution in an amount equal to the amount of money that the shareholders receiving cash dividends or distributions will receive and should have a cost basis in the shares received equal to such amount. Dividends paid by the Fund that are attributable to dividends received by the Fund from domestic corporations may qualify for the federal dividends received deduction for corporations.

Beginning in 2013, a 3.8% U.S. federal Medicare contribution tax will be imposed on net investment income, including interest, dividends, and capital gain, of U.S. individuals with income exceeding $200,000 (or $250,000 if married and filing jointly), and of estates and trusts.

Investors considering buying shares just prior to a dividend or capital gain distribution should be aware that, although the price of shares purchased at that time may reflect the amount of the forthcoming distribution, such dividend or distribution may nevertheless be taxable to them. If the Fund is the holder of record of any security on the record date for any dividends payable with respect to such security, such dividends will be included in the Fund’s gross income not as of the date received but as of the later of (a) the date such security became ex-dividend with respect to such dividends (i.e., the date on which a buyer of the security would not be entitled to receive the declared, but unpaid, dividends); or (b) the date the Fund acquired such security. Accordingly, in order to satisfy its income distribution requirements, the Fund may be required to pay dividends based on anticipated earnings, and shareholders may receive dividends in an earlier year than would otherwise be the case.

In certain situations, the Fund may, for a taxable year, defer all or a portion of its capital losses and currency losses realized after October and certain ordinary losses realized after December until the next taxable year in computing its investment company taxable income and net capital gain, which will defer the recognition of such realized losses. Such deferrals and other rules regarding gains and losses realized after October (or December) may affect the tax character of shareholder distributions.

Sales of Shares. Upon the sale or exchange of shares of the Fund, a shareholder will realize a taxable gain or loss equal to the difference between the amount realized and the shareholder’s basis in shares of the Fund. A redemption of shares by the Fund will be treated as a sale for this purpose. Such gain or loss will be treated as capital gain or loss if the shares are capital assets in the shareholder’s hands and will be long-term capital gain or loss if the shares are held for more than one year and short-term capital gain or loss if the shares are held for one year or less. Any loss realized on a sale or exchange will be disallowed to the extent the shares disposed of are replaced, including replacement through the reinvesting of dividends and capital gains distributions in the Fund, within a 61-day period beginning 30 days before and ending 30 days after the disposition of the shares. In such a case, the basis of the shares acquired will be increased to reflect the disallowed loss. Any loss realized by a shareholder on the sale of Fund shares held by the shareholder for six months or less will be treated for U.S. federal income tax purposes as a long-term capital loss to the extent of any distributions or deemed distributions of long-term capital gains received by the shareholder with respect to such share. The Medicare contribution tax described above will apply to the sale of Fund shares.

If a shareholder incurs a sales charge in acquiring shares of the Fund, disposes of those shares within 90 days and then, on or before January 31 of the following calendar year, acquires shares in a mutual fund for which the otherwise applicable sales charge is reduced by reason of a reinvestment right (e.g., an exchange privilege), the original sales charge will not be taken into account in computing gain/loss on the original shares to the extent the subsequent sales charge is reduced. Instead, the disregarded portion of the original sales charge will be added to the tax basis of the newly acquired shares. Furthermore, the same rule also applies to a disposition of the newly acquired shares made within 90 days of the second acquisition. This provision prevents shareholders from immediately deducting the sales charge by shifting their investments within a family of mutual funds.

Back-Up Withholding. In certain cases, the Fund will be required to withhold at the applicable withholding rate, and remit to the U.S. Treasury such amounts withheld from any distributions paid to a shareholder who: (i) has failed to provide a correct taxpayer identification number; (ii) is subject to back-up withholding by the IRS; (iii) has failed to certify to the Fund that such shareholder is not subject to back-up withholding; or (iv) has not certified that such shareholder is a U.S. person (including a U.S. resident alien). Back-up withholding is not an additional tax and any amount withheld may be credited against a shareholder’s U.S. federal income tax liability.

Sections 351 and 362. The Trust, on behalf of the Fund, has the right to reject an order for a purchase of shares of the Fund if the purchaser (or group of purchasers) would, upon obtaining the shares so ordered, own 80% or more of the outstanding shares of the Fund and if, pursuant to Sections 351 and 362 of the Internal Revenue Code, the Fund would have a basis in the securities different from the market value of such securities on the date of deposit. If the Fund’s basis in such securities on the date of deposit was less than market value on such date, the Fund, upon disposition of the securities, would recognize more taxable gain or less taxable loss than if its basis in the securities had been equal to market value. It is not anticipated that the Trust will exercise the right of rejection except in a case where the Trust determines that accepting the order could result in material adverse tax consequences to the Fund or its shareholders. The Trust also has the right to require information necessary to determine beneficial share ownership for purposes of the 80% determination.


Taxation of Certain Derivatives. The Fund’s transactions in zero coupon securities, non-U.S. currencies, forward contracts, options and futures contracts (including options and futures contracts on non-U.S. currencies), to the extent permitted, will be subject to special provisions of the Internal Revenue Code (including provisions relating to “hedging transactions” and “straddles”) that, among other things, may affect the character of gains and losses realized by the Fund (i.e., may affect whether gains or losses are ordinary or capital), accelerate recognition of income to the Fund and defer Fund losses. These rules could therefore affect the character, amount and timing of distributions to shareholders. These provisions also (a) will require the Fund to mark-to-market certain types of the positions in its portfolio (i.e., treat them as if they were closed out at the end of each year) and (b) may cause the Fund to recognize income without receiving cash with which to pay dividends or make distributions in amounts necessary to satisfy the distribution requirements for avoiding income and excise taxes. The Fund will monitor its transactions, will make the appropriate tax elections and will make the appropriate entries in its books and records when it acquires any zero coupon security, non-U.S. currency, forward contract, option, futures contract or hedged investment in order to mitigate the effect of these rules and prevent disqualification of the Fund as a RIC.

The Fund’s investments in so-called “Section 1256 contracts,” such as regulated futures contracts, most non-U.S. currency forward contracts traded in the interbank market and options on most security indexes, are subject to special tax rules. All Section 1256 contracts held by the Fund at the end of its taxable year are required to be marked to their market value, and any unrealized gain or loss on those positions will be included in the Fund’s income as if each position had been sold for its

fair market value at the end of the taxable year. The resulting gain or loss will be combined with any gain or loss realized by the Fund from positions in Section 1256 contracts closed during the taxable year. Provided such positions were held as capital assets and were not part of a “hedging transaction” nor part of a “straddle,” 60% of the resulting net gain or loss will be treated as long-term capital gain or loss, and 40% of such net gain or loss will be treated as short-term capital gain or loss, regardless of the period of time the positions were actually held by the Fund.

As a result of entering into swap contracts, the Fund may make or receive periodic net payments. The Fund may also make or receive a payment when a swap is terminated prior to maturity through an assignment of the swap or other closing transaction. Periodic net payments will generally constitute ordinary income or deductions, while termination of a swap will generally result in capital gain or loss (which will be a long-term capital gain or loss if the Fund has been a party to the swap for more than one year). With respect to certain types of swaps, the Fund may be required to currently recognize income or loss with respect to future payments on such swaps or may elect under certain circumstances to mark such swaps to market annually for tax purposes as ordinary income or loss.

Qualified Dividend Income. Distributions by the Fund of investment company taxable income (including any short-term capital gains), whether received in cash or shares, will be taxable either as ordinary income or as qualified dividend income, eligible for the reduced maximum rate to individuals of 15% (0% for individuals in lower tax brackets) to the extent the Fund receives qualified dividend income on the securities it holds and the Fund reports the distribution as qualified dividend income. Qualified dividend income is, in general, dividend income from taxable U.S. corporations (but generally not from U.S. REITs) and certain non-U.S. corporations (e.g., non-U.S. corporations that are not “passive foreign investment companies” and which are incorporated in a possession of the United States or in certain countries with a comprehensive tax treaty with the United States, or the stock of which is readily tradable on an established securities market in the United States (where the dividends are paid with respect to such stock)). Under current IRS guidance, the United States has appropriate comprehensive income tax treaties with the following countries: Australia, Austria, Bangladesh, Barbados, Belgium, Bulgaria, Canada, China (but not with Hong Kong, which is treated as a separate jurisdiction for U.S. tax purposes), Cyprus, the Czech Republic, Denmark, Egypt, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, India, Indonesia, Ireland, Israel, Italy, Jamaica, Japan, Kazakhstan, Latvia, Lithuania, Luxembourg, Malta, Mexico, Morocco, the Netherlands, New Zealand, Norway, Pakistan, the Philippines, Poland, Portugal, Romania, Russia, the Slovak Republic, Slovenia, South Africa, South Korea, Spain, Sri Lanka, Sweden, Switzerland, Thailand, Trinidad and Tobago, Tunisia, Turkey, Ukraine, the United Kingdom, and Venezuela. Substitute payments received by the Fund for securities lent out by the Fund will not be qualified dividend income.

A dividend from the Fund will not be treated as qualified dividend income to the extent that (i) the shareholder has not held the shares on which the dividend was paid for 61 days during the 121-day period that begins on the date that is 60 days before the date on which the shares become ex-dividend with respect to such dividend or the Fund fails to satisfy those holding period requirements with respect to the securities it holds that paid the dividends distributed to the shareholder (or, in the case of certain preferred stocks, the holding requirement of 91 days during the 181-day period beginning on the date that is 90 days before the date on which the stock becomes ex-dividend with respect to such dividend); (ii) the Fund or the shareholder is under an obligation (whether pursuant to a short sale or otherwise) to make related payments with respect to substantially similar or related property; or (iii) the shareholder elects to treat such dividend as investment income under Section 163(d)(4)(B) of the Internal Revenue Code. Dividends received by the Fund from a REIT or another RIC may be treated as qualified dividend income only to the extent the dividend distributions are attributable to qualified dividend income received by such REIT or other RIC. It is expected that dividends received by the Fund from a REIT and distributed to a shareholder generally will be taxable to the shareholder as ordinary income. The maximum 15% rate on qualified dividend income will not apply to dividends received in taxable years beginning after December 31, 2012. Distributions by the Fund of its net short-term capital gains will be taxable as ordinary income. Capital gain distributions consisting of the Fund’s net capital gains will be taxable as long-term capital gains.

If you lend your Fund shares pursuant to securities lending arrangements, you may lose the ability to use non-U.S. tax credits passed through by the Fund or to treat Fund dividends (paid while the shares are held by the borrower) as qualified dividends. Consult your financial intermediary or tax advisor. If you enter into a short sale with respect to shares of the Fund, substitute payments made to the lender of such shares may not be deductible. Consult your financial intermediary or tax advisor.

Corporate Dividends Received Deduction. Dividends paid by the Fund that are attributable to dividends received by the Fund from U.S. corporations may qualify for the U.S. federal dividends received deduction for corporations. A 46-day minimum holding period during the 90-day period that begins 45 days prior to ex-dividend date (or 91-day minimum holding period

during the 180 period beginning 90 days prior to ex-dividend date for certain preference dividends) during which risk of loss may not be diminished is required for the applicable shares, at both the Fund and shareholder level, for a dividend to be eligible for the dividends received deduction. Restrictions may apply if indebtedness, including a short sale, is attributable to the investment.

Issues Related to India and Mauritius Taxes

This discussion does not address the effect on investors, including residents of India, citizens of India (whether resident or non-resident in India or other countries, including the United States), of holding shares of the Fund. Investors should consult their own tax advisors as to these issues based upon their own personal situations.

Indian tax matters discussed herein are based on the provisions of the ITA, the provisions of the DTAA and other laws currently in force as of the date of this SAI. All such laws and the DTAA are subject to prospective and retrospective legislative amendment, administrative rulings and judicial review.

The Fund will invest in India through the Subsidiary. For U.S. federal income tax purposes, the Subsidiary has elected to be treated as an entity disregarded from its owner. Thus, for U.S. federal tax purposes, any income or loss realized by the Subsidiary will be treated as realized by the Fund. Therefore, any investment made by the Fund into the Subsidiary and any distributions received by the Fund from the Subsidiary are disregarded for U.S. federal tax purposes. Furthermore, there is no tax on the Fund’s investment in the Subsidiary or on distributions made from the Subsidiary to the Fund.

No investor will be subject to taxation in India unless such investor is a resident of India or if a non-resident, has an Indian source income or income received (whether accrued or otherwise) in India. The taxation of the Subsidiary and the Fund in India is governed by the provisions of the ITA, read with the provisions of the DTAA. As per Section 90(2) of the ITA, the provisions of the ITA would apply to the extent they are more beneficial than the provisions of the DTAA. In order to claim the beneficial provisions of the DTAA, the Subsidiary must be a tax resident of Mauritius. Because the Subsidiary is a tax resident of Mauritius, only the Subsidiary would be subject to Indian taxes.

It is expected that the Fund will not be subject to tax in India on any income distribution made to it. On the assumption that all investments of the Fund in India will be through the Subsidiary (entitled to DTAA benefits as described above) and will have no permanent establishment in India, the Fund should not be subject to any taxation in India on any gain realized on the disposal, repurchase or redemption of shares.

The Central Board of Direct Taxes in India in its Circular 789, issued on April 13, 2000, concluded that a valid residence certificate issued by the Mauritius authorities demonstrated Mauritian residency for purposes of establishing eligibility to qualify for benefits under the DTAA. The Circular was subject to judicial challenge in India by those asserting that the standards for establishing Mauritian residency for purposes of the obtaining such a certificate were insufficient to establish residency for purposes of the DTAA. The Circular was successfully overturned in certain lower Indian courts but was eventually upheld by the highest applicable court, the Supreme Court of India, on October 7, 2003, accordingly the Subsidiary should be eligible for benefits under the DTAA. However, recently issued rulings suggest that a number of factors are being considered by the Indian tax administration when assessing whether a foreign entity is eligible for the benefit of the provisions of a tax treaty, including, among others, the place of management of the foreign resident company and the level of substance in the jurisdiction in which it is incorporated. In addition, both the Indian tax administration and Indian courts seem to be very aggressive towards structures involving offshore funds investing directly or indirectly in India, in particular from Mauritius.

The Subsidiary has been incorporated in Mauritius and has obtained a tax residency certificate from the Mauritius authorities that establishes its residency in Mauritius under the DTAA. The certificate must be renewed annually. The Fund will expect the Subsidiary to maintain its Mauritius tax residency, but it cannot be assured that the Mauritius authorities will successfully renew its certificate of tax residence annually or that it will continue to be eligible to the DTAA benefits.

The Subsidiary holds a Category 1 Global Business License issued by the Financial Services Commission of Mauritius. The Subsidiary is subject to tax in Mauritius on its net income at the rate of 15%. However, a system of foreign tax credits which allows a tax credit against Mauritian taxes for foreign tax on a Mauritian entity’s foreign source income effectively reduces the Mauritius income tax rate to a maximum of 3% because the system presumes, in the absence of evidence, that the foreign tax paid is equal to 80% of the Mauritian tax. Further, the Subsidiary is not subject to capital gains tax in Mauritius

nor is it subject to tax in Mauritius on any gains from the sale of securities. Any dividends paid by the Subsidiary to the Fund will also be exempt from tax in Mauritius.

The Subsidiary will attempt to abide by the requirements of the DTAA, to maintain its residency in Mauritius, and to ensure that management and control of the Subsidiary remain in Mauritius. Therefore, so long as the DTAA is in force, the Subsidiary expects to continue to enjoy the benefits provided under the DTAA but this cannot be assured. The Indian press has recently reported that India is seeking to renegotiate the DTAA. It is therefore uncertain whether the terms of this treaty will be renegotiated or subject to a different interpretation in the future. Any change in the provisions of the DTAA or in its applicability to the Subsidiary could result in the Subsidiary and indirectly the Fund being subject to Indian income taxes, withholding taxes, and other taxes, as well as being subject to administrative or judicial assertion of such tax liabilities by the tax authorities of India. This could significantly reduce the return of the Fund on its investments and the return received by Fund shareholders. Further, it is possible even with renegotiation of the DTAA that the Indian tax authorities may seek to take the position that the Fund is not entitled to the benefits of the DTAA.

The Subsidiary is expected to have income in the form of capital gains, income from dividends and income from interest. The Indian tax consequences for the Subsidiary on account of the application of the DTAA, read with the provisions of the ITA, would be as follows (the rates are inclusive of applicable surcharges):

  • Capital gains resulting from the sale of Indian securities (including depositary receipts issued by Indian companies) will not be subject to tax in India, provided the Subsidiary does not have Permanent Establishments (“PE”) in India;
  • Dividends on shares received from an Indian company on which dividend distribution tax has been paid are exempt from tax in the hands of the shareholders. However, the Indian company distributing dividends is subject to a dividend distribution tax at the rate of 16.223%; and
  • Interest paid to the Subsidiary in respect of the debt obligations of Indian issuers will be subject to Indian income tax. The tax rate in the case of rupee-denominated debt obligations is 42.024%. In the case of foreign currency-denominated debt obligations, the tax rate is 21.012%. However, if the subsidiary is a SEBI registered sub-account, the interest from securities will be subject to tax at the rate of 21.012%.

In the event that the benefits of the DTAA are not available to the Subsidiary, or if the Subsidiary is held to have PE in India, taxation of interest and dividend income of the Subsidiary would be the same as described above. The taxation of capital gains would be as follows:

  • Long-term capital gains (being gains on sale of securities held for a period of more than twelve months) listed on a recognized stock exchange would not be taxable in India provided Securities Transaction Tax (“STT”) has been paid on the same (as discussed below);
  • Short-term capital gains (being gains on sale of securities held for a period of twelve months or less) from the sale of Indian securities listed on a recognized stock exchange will be taxed at the rate of 15.759% provided STT has been paid on the same;
  • Capital gains realized on sale of listed equity shares not executed on a recognized stock exchange in India and other Indian-listed securities would be taxed at the rate of 21.012% for long-term gains and at 42.024% in the case of short-term gains;*
  • Long-term capital gains arising to the Subsidiary from the sale of unlisted securities will be taxed at the rate of 21.012% and short-term capital gains will be taxed at the rate of 42.024%; and
  • Capital gains arising from the transfer of depositary receipts outside India between non-resident investors will not be subject to tax in India.

* However, if the Subsidiary is a SEBI registered sub-account, the rates will be 10.506% and 31.518%, respectively.

In a ruling issued by the Authority for Advance Rulings in India, gains earned by a private equity fund based in Mauritius were held to be “business income.” It is possible that the Indian tax authorities may take a similar view in the case of the Subsidiary. In that event, such gains will not be taxable in India so long as the Fund/Subsidiary do not have a PE in India. In the event that the Fund/Subsidiary are held to have a PE in India, gains attributable to the PE would be taxable in India at the rate of 42.024%.

Indian Minimum Alternative Tax

In the event that the benefits of the DTAA are not available to the Subsidiary, or if the Subsidiary is held to have PE in India, the Subsidiary may be subject to a Minimum Alternate Tax (“MAT”). In the event that a company’s tax liability is less than 18% of its book profits, then instead of paying income tax at rates provided otherwise under the ITA, the company will pay MAT on the adjusted book profits as prescribed below:

Companies For taxable income exceeding INR 10 million For taxable income less than or equal to INR 10 million
Indian company
20.008%
19.055%
        
Foreign company having a permanent establishment in India (including a branch and a project office) 19.436% 19.055%

Indian Securities Transaction Tax

All transactions entered on a recognized stock exchange in India will be subject to STT levied on the transaction value. In the case of the purchase/sale of listed equity shares which is settled by way of actual delivery or transfer of the equity share, STT will be levied at the rate of 0.125% on both the buyer and seller of the equity share. For sale of equity shares settled otherwise than by way actual delivery or transfer of the equity share, STT will be levied at the rate of 0.025% on the seller of the equity share. A seller of derivatives would be subjected to an STT of 0.017%. The STT can be set off against business income tax calculated as per provisions of ITA.

The foregoing is based upon current interpretation and practice and is subject to future changes in the tax laws of India or Mauritius and in the DTAA. Any change in the DTAA’s application could have a material adverse affect on the returns of the Fund. Further, it is possible that the Indian tax authorities may seek to take the position that the Fund is not entitled to the benefits of the DTAA.

The Direct Taxes Code, 2010

The New Taxes Code has been tabled before the Lok Sabha (the lower house of the Indian Parliament), which, if enacted, will replace the existing ITA with effect from April 1, 2012. The New Taxes Code proposes several changes in the tax regime and administration thereof. There are several provisions therein which may severely impact the proposed structure, including the ones set out below which are based on the current draft of the New Taxes Code, which may not be enacted in the current draft form. They are as follows:

  • General anti-avoidance rules would apply (depending on rules yet to be framed by the Indian government) where foreign entities claiming the benefit of a tax treaty lack commercial substance in their country of incorporation. In cases where such anti-avoidance provisions are successfully invoked, the provisions of applicable tax treaties would be overridden.
  • Specific rules with respect to the documentation to be provided by a foreign entity which claims the benefit of a tax treaty into which India entered. In particular, the current draft of the New Taxes Code provides that a person shall be entitled to claim relief under the relevant tax treaty only upon receipt of a tax residency certificate in the “prescribed form.” Currently, there is no guidance on what the “prescribed form” is. This seems to suggest that a certificate of residence would be the minimum requirement for treaty entitlement.
  • The Subsidiary can be considered to be a resident in India if its place of effective management at any time in the year is in India. “Place of effective management” is defined in the New Taxes Code as (i) the place where the board of directors of the company or its executive directors, as the case may be, make their decisions; or (ii) in a case where the board of directors routinely approve the commercial and strategic decisions made by the executive directors or officers of the company, the place where such executive directors or officers of the company perform their functions.

Excess Inclusion Income. Under current law, the Fund will block unrelated business taxable income from being realized by its tax-exempt shareholders. Notwithstanding the foregoing, a tax-exempt shareholder could realize unrelated business taxable income by virtue of its investment in the Fund if shares in the Fund constitute debt-financed property in the hands of the tax-exempt shareholder within the meaning of Section 514(b) of the Internal Revenue Code. Certain types of income received by the Fund from REITs, real estate mortgage investment conduits, taxable mortgage pools or other investments

may cause the Fund to report some or all of its distributions as “excess inclusion income.” To Fund shareholders, such excess inclusion income may (i) constitute taxable income, as unrelated business taxable income for those shareholders who would otherwise be tax-exempt such as individual retirement accounts, 401(k) accounts, Keogh plans, pension plans and certain charitable entities; (ii) not be offset by otherwise allowable deductions for tax purposes; (iii) not be eligible for reduced U.S. withholding for non-U.S. shareholders even from tax treaty countries; and (iv) cause the Fund to be subject to tax if certain “disqualified organizations,” as defined by the Internal Revenue Code, are Fund shareholders. If a charitable remainder annuity trust or a charitable remainder unitrust (each as defined in Section 664 of the Internal Revenue Code) has unrelated business taxable income (“UBTI”) for a taxable year, a 100% excise tax on the UBTI is imposed on the trust.

Non-U.S. Investments. Under Section 988 of the Internal Revenue Code, gains or losses attributable to fluctuations in exchange rates between the time the Fund accrues income or receivables or expenses or other liabilities denominated in a non-U.S. currency and the time the Fund actually collects such income or pays such liabilities are generally treated as ordinary income or ordinary loss. In general, gains (and losses) realized on debt instruments will be treated as Section 988 gain (or loss) to the extent attributable to changes in exchange rates between the U.S. dollar and the currencies in which the instruments are denominated. Similarly, gains or losses on non-U.S. currency, non-U.S. currency forward contracts and certain non-U.S. currency options or futures contracts denominated in non-U.S currency, to the extent attributable to fluctuations in exchange rates between the acquisition and disposition dates, are also treated as ordinary income or loss unless the Fund were to elect otherwise.

The Fund may be subject to non-U.S. income taxes withheld at the source. The Fund, if permitted to do so, may elect to “pass through” to its investors the amount of non-U.S. income taxes paid by the Fund provided that the Fund held the security on the dividend settlement date and for at least 15 additional days immediately before and/or thereafter, with the result that each investor with respect to shares of the Fund held for a minimum 16-day holding period at the time of deemed distribution will (i) include in gross income, even though not actually received, the investor’s pro rata share of the Fund’s non-U.S. income taxes, and (ii) either deduct (in calculating U.S. taxable income, but only for investors who itemize their deductions on their personal tax returns) or credit (in calculating U.S. federal income tax) the investor’s pro rata share of the Fund’s non-U.S. income taxes. A non-U.S. person invested in the Fund in a year that the Fund elects to “pass through” its non-U.S. taxes may be treated as receiving additional dividend income subject to U.S. withholding tax. A non-U.S. tax credit may not exceed the investor’s U.S. federal income tax otherwise payable with respect to the investor’s non-U.S. source income. For this purpose, shareholders must treat as non-U.S. source gross income (i) their proportionate shares of non-U.S. taxes paid by the Fund and (ii) the portion of any dividend paid by the Fund that represents income derived from non-U.S. sources; the Fund’s gain from the sale of securities will generally be treated as U.S.-source income. Certain limitations will be imposed to the extent to which the non-U.S. tax credit may be claimed.

Passive Foreign Investment Companies. If the Fund purchases shares in “passive foreign investment companies” (“PFICs”), it may be subject to U.S. federal income tax on a portion of any “excess distribution” or gain from the disposition of such shares even if such income is distributed as a taxable dividend by the Fund to its shareholders. Additional charges in the nature of interest may be imposed on the Fund in respect of deferred taxes arising from such distributions or gains.

If the Fund were to invest in a PFIC and elect to treat the PFIC as a “qualified electing fund” under the Internal Revenue Code, in lieu of the foregoing requirements, the Fund might be required to include in income each year a portion of the ordinary earnings and net capital gains of the qualified electing fund, even if not distributed to the Fund, and such amounts would be subject to the 90% and excise tax distribution requirements described above. In order to make this election, the Fund would be required to obtain certain annual information from the PFICs in which it invests, which may be difficult or impossible to obtain.

Alternatively, the Fund may make a mark-to-market election that would result in the Fund being treated as if it had sold and repurchased its PFIC stock at the end of each year. In such case, the Fund would report any such gains as ordinary income and would deduct any such losses as ordinary losses to the extent of previously recognized gains. The election must be made separately for each PFIC owned by the Fund and, once made, would be effective for all subsequent taxable years, unless revoked with the consent of the IRS. By making the election, the Fund could potentially ameliorate the adverse tax consequences with respect to its ownership of shares in a PFIC, but in any particular year may be required to recognize income in excess of the distributions it receives from PFICs and its proceeds from dispositions of PFIC stock. The Fund may have to distribute this “phantom” income and gain to satisfy the 90% distribution requirement and to avoid imposition of the 4% excise tax.

The Fund will make the appropriate tax elections, if possible, and take any additional steps that are necessary to mitigate the effects of these rules.

Reporting. If a shareholder recognizes a loss with respect to the Fund’s shares of $2 million or more for an individual shareholder or $10 million or more for a corporate shareholder, the shareholder must file with the IRS a disclosure statement on Form 8886. Direct shareholders of portfolio securities are in many cases exempted from this reporting requirement, but under current guidance, shareholders of a RIC are not exempted. The fact that a loss is reportable under these regulations does not affect the legal determination of whether the taxpayer’s treatment of the loss is proper. Shareholders should consult their tax advisors to determine the applicability of these regulations in light of their individual circumstances.

Other Taxes. Dividends, distributions and redemption proceeds may also be subject to additional state, local and non-U.S. taxes depending on each shareholder’s particular situation.

Taxation of Non-U.S. Shareholders. Dividends paid by the Fund to non-U.S. shareholders are generally subject to withholding tax at a 30% rate or a reduced rate specified by an applicable income tax treaty to the extent derived from investment income and short-term capital gains. Dividends paid by the Fund from net tax-exempt income or long-term capital gains are generally not subject to such withholding tax. In order to obtain a reduced rate of withholding, a non-U.S. shareholder will be required to provide an IRS Form W-8BEN certifying its entitlement to benefits under a treaty. The withholding tax does not apply to regular dividends paid to a non-U.S. shareholder who provides a Form W-8ECI, certifying that the dividends are effectively connected with the non-U.S. shareholder’s conduct of a trade or business within the United States. Instead, the effectively connected dividends will be subject to regular U.S. income tax as if the non-U.S. shareholder were a U.S. shareholder. A non-U.S. corporation receiving effectively connected dividends may also be subject to additional “branch profits tax” imposed at a rate of 30% (or lower treaty rate). A non-U.S. shareholder who fails to provide an IRS Form W-8BEN or other applicable form may be subject to back-up withholding at the appropriate rate.

In general, U.S. federal withholding tax will not apply to any gain or income realized by a non-U.S. shareholder in respect of any distributions of net long-term capital gains over net short-term capital losses, tax-exempt interest dividends, or upon the sale or other disposition of shares of the Fund. If the Fund’s direct or indirect interests in U.S. real property were to exceed certain levels, distributions to a non-U.S. shareholder from the Fund attributable to a REIT’s distribution to the Fund of gain from a sale or exchange of a U.S. real property interest and, in the case of a non-U.S. shareholder owning more than 5% of the class of shares throughout either such person’s holding period for the redeemed shares or, if shorter, the previous five years, the gain on redemption will be treated as real property gain subject to additional taxes or withholding and may result in the non-U.S. shareholder having additional filing requirements.

For taxable years beginning before January 1, 2012, distributions that the Fund reports as “short-term capital gain dividends” or “long-term capital gain dividends” are not treated as such to a recipient non-U.S. shareholder if the distribution is attributable to gain received from the sale or exchange of U.S. real property or an interest in a U.S. real property holding corporation and the Fund’s direct or indirect interests in U.S. real property exceed certain levels. Instead, if the non-U.S. shareholder has not owned more than 5% of the outstanding shares of the Fund at any time during the one year period ending on the date of distribution, such distribution is subject to 30% withholding by the Fund and is treated as ordinary dividends to the non-U.S. shareholder; if the non-U.S. shareholder owned more than 5% of the outstanding shares of the Fund at any time during the one year period ending on the date of the distribution, such distribution is treated as real property gain subject to 35% withholding tax and could subject the non-U.S. shareholder to U.S. filing requirements. Additionally, if the Fund’s direct or indirect interests in U.S. real property were to exceed certain levels, a non-U.S. shareholder realizing gains upon redemption from the Fund on or before December 31, 2011 could be subject to the 35% withholding tax and U.S. filing requirements unless more than 50% of the Fund’s shares were owned by U.S. persons at such time or unless the non-U.S. person had not held more than 5% of the Fund’s outstanding shares throughout either such person’s holding period for the redeemed shares or, if shorter, the previous five years.

The rules laid out in the previous two paragraphs, other than the withholding rules, will apply notwithstanding the Fund’s participation in a wash sale transaction or its payment of a substitute dividend.

Provided that 50% or more of the value of the Fund’s stock is held by U.S. shareholders, distributions of U.S. real property interests (including securities in a U.S. real property holding corporation, unless such corporation is regularly traded on an established securities market and the Fund has held 5% or less of the outstanding shares of the corporation during the five-year period ending on the date of distribution) occurring on or before December 31, 2011, in redemption of a foreign shareholder’s shares of the Fund will cause the Fund to recognize gain. If the Fund is required to recognize gain, the amount

of gain recognized will be equal to the fair market value of such interests over the Fund’s adjusted bases to the extent of the greatest foreign ownership percentage of the Fund during the five-year period ending on the date of redemption.

For taxable years beginning before January 1, 2012, properly reported dividends are generally exempt from U.S. federal withholding tax where they (i) are paid in respect of the Fund’s “qualified net interest income” (generally, the Fund’s U.S. source interest income, other than certain contingent interest and interest from obligations of a corporation or partnership in which the Fund is at least a 10% shareholder, reduced by expenses that are allocable to such income), or (ii) are paid in respect of the Fund’s “qualified short-term capital gains” (generally, the excess of the Fund’s net short-term capital gain over the Fund’s long-term capital loss for such taxable year). However, depending on its circumstances, the Fund may report all, some or none of its potentially eligible dividends as such qualified net interest income or as qualified short-term capital gains and/or treat such dividends, in whole or in part, as ineligible for this exemption from withholding. In order to qualify for this exemption from withholding, a non-U.S. shareholder will need to comply with applicable certification requirements relating to its non-U.S. status (including, in general, furnishing an IRS Form W-8BEN or substitute Form). In the case of shares held through an intermediary, the intermediary may withhold even if the Fund reports the payment as qualified net interest income or qualified short-term capital gain. Non-U.S. shareholders should contact their intermediaries with respect to the application of these rules to their accounts.

A 30% withholding tax will be imposed on dividends paid after December 31, 2013, and redemption proceeds paid after December 31, 2014, to (i) foreign financial institutions, including non-U.S. investment funds, unless they agree to collect and disclose to the IRS information regarding their direct and indirect U.S. account holders; and (ii) certain other foreign entities, unless they certify certain information regarding their direct and indirect U.S. owners. To avoid withholding, foreign financial institutions will need to enter into agreements with the IRS that state that they will provide the IRS information, including the name, address and taxpayer identification number of direct and indirect U.S. account holders; comply with due diligence procedures with respect to the identification of U.S. accounts; report to the IRS certain information with respect to U.S. accounts maintained; agree to withhold tax on certain payments made to non-compliant foreign financial institutions or to account holders who fail to provide the required information; and determine certain other information as to their account holders. Other foreign entities will need to provide the name, address, and taxpayer identification number of each substantial U.S. owner or certifications of no substantial U.S. ownership, unless certain exceptions apply.

Shares of the Fund held by a non-U.S. shareholder at death will be considered situated within the United States and subject to the U.S. estate tax for decedents dying after December 31, 2011, with a lookthrough rule applying before such date.

The foregoing discussion is a summary of certain material U.S. federal income tax considerations only and is not intended as a substitute for careful tax planning. Purchasers of shares should consult their own tax advisors as to the tax consequences of investing in such shares, including consequences under state, local and non-U.S. tax laws. Finally, the foregoing discussion is based on applicable provisions of the Internal Revenue Code, regulations, judicial authority and administrative interpretations in effect on the date of this SAI. Changes in applicable authority could materially affect the conclusions discussed above, and such changes often occur.

General Description of the Trust and its Fund

The Trust currently consists of more than 190 investment series or portfolios. The Trust was organized as a Delaware statutory trust on December 16, 1999 and is authorized to have multiple series or portfolios. The Trust is an open-end management investment company registered with the Securities and Exchange Commission (the “SEC”) under the Investment Company Act of 1940, as amended (the “1940 Act”). The offering of the Trust’s shares is registered under the Securities Act of 1933, as amended (the “1933 Act”). This SAI relates solely to the Fund.

The investment objective of the Fund is to seek investment results that correspond generally to the price and yield performance, before fees and expenses, of a specified benchmark index (the “Underlying Index”) representing publicly-traded equity securities of issuers in a particular broad market, market segment, market sector or group of industries. The Fund is managed by BlackRock Fund Advisors (“BFA”), a wholly-owned subsidiary of BTC, which in turn is indirectly wholly-owned by BlackRock, Inc.

The Fund offers and issues shares at their net asset value per share (“NAV”) only in aggregations of a specified number of shares (“Creation Unit”), generally in exchange for a designated portfolio of securities (including any portion of such securities for which cash may be substituted) included in its Underlying Index (the “Deposit Securities”), together with the deposit of a specified cash payment (the “Cash Component”). Shares of the Fund are listed and trade on NYSE Arca, Inc. (“NYSE Arca” or the “Listing Exchange”), a national securities exchange. Shares trade in the secondary market and elsewhere at market prices that may be at, above or below NAV. Shares are redeemable only in Creation Units, and, generally, in exchange for portfolio securities and a Cash Component. Creation Units typically are a specified number of shares, generally 200,000 or multiples thereof.

The Trust reserves the right to permit or require that creations and redemptions of shares are effected fully or partially in cash. Shares may be issued in advance of receipt of Deposit Securities, subject to various conditions, including a requirement to maintain with the Trust a cash deposit equal to at least 105% and up to 115%, which percentage BFA may change from time to time, of the market value of the omitted Deposit Securities. See the Creation and Redemption of Creation Units section of this SAI. Transaction fees associated with creations or redemptions that include a cash portion may be higher than the transaction fees associated with in-kind creations or redemptions. In all cases, conditions and fees will be limited in accordance with the requirements of SEC rules and regulations applicable to management investment companies offering redeemable securities.

Exchange Listing and Trading

A discussion of exchange listing and trading matters associated with an investment in the Fund is contained in the Shareholder Information section of the Fund’s Prospectus. The discussion below supplements, and should be read in conjunction with, that section of the Prospectus.

Shares of the Fund are listed for trading, and trade throughout the day, on the Listing Exchange and other secondary markets. Shares of the Fund may also be listed on certain non-U.S. exchanges. There can be no assurance that the requirements of the Listing Exchange necessary to maintain the listing of shares of the Fund will continue to be met. The Listing Exchange may, but is not required to, remove the shares of the Fund from listing if (i) following the initial 12-month period beginning upon the commencement of trading of Fund shares, there are fewer than 50 beneficial owners of shares of the Fund for 30 or more consecutive trading days, (ii) the value of the Underlying Index on which the Fund is based is no longer calculated or available, (iii) the “indicative optimized portfolio value” (“IOPV”) of the Fund is no longer calculated or available, or (iv) any other event shall occur or condition shall exist that, in the opinion of the Listing Exchange, makes further dealings on the Listing Exchange inadvisable. The Listing Exchange will also remove shares of the Fund from listing and trading upon termination of the Fund.

As in the case of other publicly-traded securities, when you buy or sell shares through a broker you will incur a brokerage commission determined by that broker.

In order to provide additional information regarding the indicative value of shares of the Fund, the Listing Exchange or a market data vendor disseminates information every 15 seconds through the facilities of the Consolidated Tape Association, or through other widely disseminated means, an updated IOPV for the Fund as calculated by an information provider or market data vendor. The Trust is not involved in or responsible for any aspect of the calculation or dissemination of the IOPVs and makes no representation or warranty as to the accuracy of the IOPVs.

An IOPV has an equity securities component and a cash component. The equity securities values included in an IOPV are the values of the Deposit Securities for the Fund. While the IOPV reflects the current market value of the Deposit Securities required to be deposited in connection with the purchase of a Creation Unit, it does not necessarily reflect the precise composition of the current portfolio of securities held by the Fund at a particular point in time because the current portfolio of the Fund may include securities that are not a part of the current Deposit Securities. Therefore, the Fund’s IOPV disseminated during the Listing Exchange trading hours should not be viewed as a real-time update of the Fund’s NAV, which is calculated only once a day.

The cash component included in an IOPV consists of estimated accrued interest, dividends and other income, less expenses. If applicable, each IOPV also reflects changes in currency exchange rates between the U.S. dollar and the applicable currency.

The Trust reserves the right to adjust the share prices of the Fund in the future to maintain convenient trading ranges for investors. Any adjustments would be accomplished through stock splits or reverse stock splits, which would have no effect on the net assets of the Fund or an investor’s equity interest in the Fund.

Investment Strategies and Risks

The Fund seeks to achieve its objective by investing primarily in securities that comprise its Underlying Index and through transactions that provide substantially similar exposure to securities in the Underlying Index. The Fund operates as an index fund and will not be actively managed. Adverse performance of a security in the Fund’s portfolio will ordinarily not result in the elimination of the security from the Fund’s portfolio.

The Fund engages in representative sampling, which is investing in a sample of securities selected by BFA to have a collective investment profile similar to that of the Fund’s Underlying Index. Securities selected have aggregate investment characteristics (based on market capitalization and industry weightings), fundamental characteristics (such as return variability, earnings valuation and yield) and liquidity measures similar to those of the Underlying Index. Funds that use representative sampling generally do not hold all of the securities that are in the Underlying Index.

Currency Transactions. The Fund does not expect to engage in currency transactions for the purpose of hedging against declines in the value of the Fund’s assets that are denominated in a non-U.S. currency. The Fund may enter into non-U.S. currency forward and non-U.S. currency futures contracts to facilitate local securities settlements or to protect against currency exposure in connection with its distributions to shareholders, but may not enter into such contracts for speculative purposes.

A forward currency contract is an obligation to purchase or sell a specific currency at a future date, which may be any fixed number of days from the date of the contract agreed upon by the parties, at a price set at the time of the contract. A currency futures contract is a contract involving an obligation to deliver or acquire the specified amount of a specific currency, at a specified price and at a specified future time. Currency futures contracts may be settled on a net cash payment basis rather than by the sale and delivery of the underlying currency. To the extent required by law, liquid assets committed to futures contracts will be maintained.

Foreign exchange transactions involve a significant degree of risk and the markets in which foreign exchange transactions are effected are highly volatile, highly specialized and highly technical. Significant changes, including changes in liquidity and prices, can occur in such markets within very short periods of time, often within minutes. Foreign exchange trading risks include, but are not limited to, exchange rate risk, counterparty risk, maturity gap, interest rate risk, and potential interference by foreign governments through regulation of local exchange markets, foreign investment or particular transactions in non-U.S. currency. If BFA utilizes foreign exchange transactions at an inappropriate time or judges market conditions, trends or correlations incorrectly, foreign exchange transactions may not serve their intended purpose of improving the correlation of the Fund’s return with the performance of the Underlying Index and may lower the Fund’s return. The Fund could experience losses if the value of its currency forwards, options and futures positions were poorly correlated with its other investments or

if it could not close out its positions because of an illiquid market. In addition, each Underlying Fund could incur transaction costs, including trading commissions, in connection with certain non-U.S. currency transactions.

Diversification Status. The Fund is classified as “diversified.” With respect to 75% of the Fund’s total assets, a “diversified” fund is limited by the 1940 Act such that it does not invest more than 5% of its total assets in securities of any one issuer and does not acquire more than 10% of the outstanding voting securities of any one issuer (excluding cash and cash items, government securities, and securities of other investment companies). The remaining 25% of the Fund’s total assets may be invested in any manner.

The Fund intends to maintain the required level of diversification and otherwise conduct its operations so as to qualify as a Regulated Investment Company (“RIC”) for purposes of the U.S. Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”), and to relieve the Fund of any liability for U.S. federal income tax to the extent that its earnings are distributed to shareholders, provided that the Fund satisfies a minimum distribution requirement. Compliance with the diversification requirements of the Internal Revenue Code may limit the investment flexibility of the Fund and may make it less likely that the Fund will meet its investment objective.

Futures and Options. Futures contracts and options may be used by the Fund to simulate investment in its Underlying Index, to facilitate trading or to reduce transaction costs. The Fund may enter into futures contracts and options that are traded on a U.S. or non-U.S. exchange. The Fund will not use futures or options for speculative purposes. The Fund intends to use futures and options in accordance with Rule 4.5 of the Commodity Exchange Act (“CEA”). The Trust, on behalf of the Fund, has claimed an exclusion from the definition of the term “commodity pool operator” in accordance with Rule 4.5 so that each Underlying Fund is not subject to registration or regulation as a commodity pool operator under the CEA. On February 11, 2011, however, the Commodity Futures Trading Commission (“CFTC”) proposed certain regulatory changes that would subject registered investment companies to regulation by the CFTC if a fund invests more than a prescribed level of its liquidation value in futures and certain other instruments, or if the fund markets itself as providing investment exposure to such instruments. If these regulatory changes are ultimately adopted by the CFTC, each Underlying Fund may be subject to the CFTC registration requirements, and the disclosure and operations of the Fund would need to comply with all applicable regulations governing commodity pools. Compliance with these additional registration and regulatory requirements would increase Fund expenses. BFA may also be subject to CFTC regulation if each Underlying Fund is deemed to be a commodity pool. Other potentially adverse regulatory initiatives could also develop.

Futures contracts provide for the future sale by one party and purchase by another party of a specified amount of a specific instrument or index at a specified future time and at a specified price. Stock index contracts are based on investments that reflect the market value of common stock of the firms included in the investments. The Fund may enter into futures contracts to purchase securities indexes when BFA anticipates purchasing the underlying securities and believes prices will rise before the purchase will be made. To the extent required by law, liquid assets committed to futures contracts will be maintained.

A call option gives a holder the right to purchase a specific security at a specified price (“exercise price”) within a specified period of time. A put option gives a holder the right to sell a specific security at a specified exercise price within a specified period of time. The initial purchaser of a call option pays the “writer” a premium, which is paid at the time of purchase and is retained by the writer whether or not such option is exercised. The Fund may purchase put options to hedge its portfolio against the risk of a decline in the market value of securities held and may purchase call options to hedge against an increase in the price of securities it is committed to purchase. The Fund may write put and call options along with a long position in options to increase its ability to hedge against a change in the market value of the securities it holds or is committed to purchase. Investments in futures contracts and other investments that contain leverage may require each Underlying Fund to maintain liquid assets. Generally, each Underlying Fund maintains an amount of liquid assets equal to its obligations relative to the position involved, adjusted daily on a marked-to-market basis. With respect to futures contracts that are contractually required to “cash-settle,” each Underlying Fund maintains liquid assets in an amount at least equal to each Underlying Fund’s daily marked-to-market obligation (i.e., each Underlying Fund’s daily net liability, if any), rather than the contracts’ notional value (i.e., the value of the underlying asset). By maintaining assets equal to its net obligation under cash-settled futures contracts, the Fund may employ leverage to a greater extent than if each Underlying Fund set aside assets equal to the futures contracts’ full notional value. The Fund bases its asset maintenance policies on methods permitted by the staff of the SEC and may modify these policies in the future to comply with any changes in the guidance articulated from time to time by the SEC or its staff.

Illiquid Securities. The Fund may invest up to an aggregate amount of 15% of its net assets in illiquid securities (calculated at the time of investment). Illiquid securities include securities subject to contractual or other restrictions on resale and other instruments that lack readily available markets.

Lending Portfolio Securities. The Fund may lend portfolio securities to certain creditworthy borrowers, including borrowers affiliated with BFA. The borrowers provide collateral that is maintained in an amount at least equal to the current market value of the securities loaned. No securities loan shall be made on behalf of the Fund if, as a result, the aggregate value of all securities loans of the Fund exceeds one-third of the value of the Fund’s total assets (including the value of the collateral received). The Fund may terminate a loan at any time and obtain the return of the securities loaned. The Fund receives the value of any interest or cash or non-cash distributions paid on the loaned securities.

With respect to loans that are collateralized by cash, the borrower will be entitled to receive a fee based on the amount of cash collateral. The Fund is compensated by the difference between the amount earned on the reinvestment of cash collateral and the fee paid to the borrower. In the case of collateral other than cash, the Fund is compensated by a fee paid by the borrower equal to a percentage of the market value of the loaned securities. Any cash collateral may be reinvested in certain short-term instruments either directly on behalf of the Fund or through one or more joint accounts or money market funds, including those affiliated with BFA; such reinvestments are subject to investment risk. BFA may receive compensation for these investments.

Securities lending involves exposure to certain risks, including operational risk (i.e., the risk of losses resulting from problems in the settlement and accounting process), “gap” risk (i.e., the risk of a mismatch between the return on cash collateral reinvestments and the fees the Fund has agreed to pay a borrower), and credit, legal, counterparty and market risk. If a securities lending counterparty were to default, the Fund would be subject to the risk of a possible delay in receiving collateral or in recovering the loaned securities, or to a possible loss of rights in the collateral. In the event a borrower does not return the Fund’s securities as agreed, the Fund may experience losses if the proceeds received from liquidating the collateral do not at least equal the value of the loaned security at the time the collateral is liquidated, plus the transaction costs incurred in purchasing replacement securities. This event could trigger adverse tax consequences for the Fund. Substitute payments for dividends received by the Fund for securities loaned out by the Fund will not be considered qualified dividend income. The Fund takes the tax effects of this difference into account in its securities lending program.

The Fund pays a portion of the interest or fees earned from securities lending to a borrower as described above and to a securities lending agent who administers the lending program in accordance with guidelines approved by the Trust’s Board of Trustees (the “Board” or the “Trustees”). To the extent that the Fund engages in securities lending, BTC acts as securities lending agent for the Fund, subject to the overall supervision of BFA. BTC receives a portion of the revenues generated by securities lending activities as compensation for its services.

Non-U.S. Securities. The Fund intends to purchase publicly-traded common stocks of non-U.S. issuers. To the extent the Fund invests in stocks of non-U.S. issuers, the Fund’s investment in such stocks may be in the form of American Depositary Receipts (“ADRs”), Global Depositary Receipts (“GDRs”) and European Depositary Receipts (“EDRs”) (collectively, “Depositary Receipts”). Depositary Receipts are receipts, typically issued by a bank or trust issuer, which evidence ownership of underlying securities issued by a non-U.S. issuer. For ADRs, the depository is typically a U.S. financial institution and the underlying securities are issued by a non-U.S. issuer. For other forms of Depositary Receipts, the depository may be a non-U.S. or a U.S. entity, and the underlying securities may be issued by a non-U.S. or a U.S. issuer. Depositary Receipts are not necessarily denominated in the same currency as their underlying securities. Generally, ADRs, issued in registered form, are designed for use in the U.S. securities markets, and EDRs, issued in bearer form, are designed for use in European securities markets. GDRs are tradable both in the United States and in Europe and are designed for use throughout the world.

The Fund will not invest in any unlisted Depositary Receipt or any Depositary Receipt that BFA deems illiquid at the time of purchase or for which pricing information is not readily available. In general, Depositary Receipts must be sponsored, but the Fund may invest in unsponsored Depositary Receipts under certain limited circumstances. The issuers of unsponsored Depositary Receipts are not obligated to disclose material information in the United States. Therefore, there may be less information available regarding such issuers and there may be no correlation between available information and the market value of the Depositary Receipts.

Investing in the securities of non-U.S. issuers involves special risks and considerations not typically associated with investing in U.S. issuers. These include differences in accounting, auditing and financial reporting standards, the possibility of expropriation or confiscatory taxation, adverse changes in investment or exchange control regulations, political instability

which could affect U.S. investments in non-U.S. countries, and potential restrictions on the flow of international capital. Non-U.S. issuers may be subject to less governmental regulation than U.S. issuers. Moreover, individual non-U.S. economies may differ favorably or unfavorably from the U.S. economy in such respects as growth of gross domestic product, rate of inflation, capital reinvestment, resource self-sufficiency and balance of payment positions.

Options on Futures Contracts. An option on a futures contract, as contrasted with the direct investment in such a contract, gives the purchaser the right, in return for the premium paid, to assume a position in the underlying futures contract at a specified exercise price at any time prior to the expiration date of the option. Upon exercise of an option, the delivery of the futures position by the writer of the option to the holder of the option will be accompanied by delivery of the accumulated balance in the writer’s futures margin account that represents the amount by which the market price of the futures contract exceeds (in the case of a call) or is less than (in the case of a put) the exercise price of the option on the futures contract. The potential for loss related to the purchase of an option on a futures contract is limited to the premium paid for the option plus transaction costs. Because the value of the option is fixed at the point of sale, there are no daily cash payments by the purchaser to reflect changes in the value of the underlying contract; however, the value of the option changes daily and that change would be reflected in the NAV of the Fund. The potential for loss related to writing call options is unlimited. The potential for loss related to writing put options is limited to the agreed upon price per share, also known as the “strike price,” less the premium received from writing the put.

The Fund may purchase and write put and call options on futures contracts that are traded on an exchange as a hedge against changes in value of its portfolio securities, or in anticipation of the purchase of securities, and may enter into closing transactions with respect to such options to terminate existing positions. There is no guarantee that such closing transactions can be effected.

Upon entering into a futures contract, the Fund will be required to deposit with the broker an amount of cash or cash equivalents known as “initial margin,” which is in the nature of a performance bond or good faith deposit on the contract and is returned to each Underlying Fund upon termination of the futures contract, assuming all contractual obligations have been satisfied. Subsequent payments, known as “variation margin,” to and from the broker will be made daily as the price of the index underlying the futures contract fluctuates, making the long and short positions in the futures contract more or less valuable, a process known as “marking-to-market.” At any time prior to the expiration of a futures contract, each Underlying Fund may elect to close the position by taking an opposite position, which will operate to terminate the Fund’s existing position in the contract.

Repurchase Agreements. A repurchase agreement is an instrument under which the purchaser (i.e., the Fund) acquires the security and the seller agrees, at the time of the sale, to repurchase the security at a mutually agreed upon time and price, thereby determining the yield during the purchaser’s holding period. Repurchase agreements may be construed to be collateralized loans by the purchaser to the seller secured by the securities transferred to the purchaser. If a repurchase agreement is construed to be a collateralized loan, the underlying securities will not be considered to be owned by the Fund but only to constitute collateral for the seller’s obligation to pay the repurchase price, and, in the event of a default by the seller, the Fund may suffer time delays and incur costs or losses in connection with the disposition of the collateral.

In any repurchase transaction, the collateral for a repurchase agreement may include: (i) cash items; (ii) obligations issued by the U.S. government or its agencies or instrumentalities; or (iii) obligations that, at the time the repurchase agreement is entered into, are rated in the highest rating category generally by at least two nationally recognized statistical rating organizations (“NRSRO”), or, if unrated, determined to be of comparable quality by BFA. Collateral, however, is not limited to the foregoing and may include, for example, obligations rated below the highest category by NRSROs. Collateral for a repurchase agreement may also include securities that the Fund could not hold directly without the repurchase obligation. Irrespective of the type of collateral underlying the repurchase agreement, in the case of a repurchase agreement entered into by a non-money market fund, the repurchase obligation of a seller must be of comparable credit quality to securities which are rated in one of the two highest rating categories by any NRSRO.

Repurchase agreements pose certain risks for the Fund, should it decide to utilize them. Such risks are not unique to the Fund, but are inherent in repurchase agreements. The Fund seeks to minimize such risks, but because of the inherent legal uncertainties involved in repurchase agreements, such risks cannot be eliminated. Lower quality collateral and collateral with longer maturities may be subject to greater price fluctuations than higher quality collateral and collateral with shorter maturities. If the repurchase agreement counterparty were to default, lower quality collateral may be more difficult to liquidate than higher quality collateral. Should the counterparty default and the amount of collateral not be sufficient to cover

the counterparty’s repurchase obligation, the Fund would retain the status of an unsecured creditor of the counterparty (i.e., the position the Fund would normally be in if it were to hold, pursuant to its investment policies, other unsecured debt securities of the defaulting counterparty) with respect to the amount of the shortfall. As an unsecured creditor, the Fund would be at risk of losing some or all of the principal and income involved in the transaction.

Reverse Repurchase Agreements. Reverse repurchase agreements involve the sale of securities with an agreement to repurchase the securities at an agreed-upon price, date and interest payment and have the characteristics of borrowing. Generally, the effect of such transactions is that each Underlying Fund can recover all or most of the cash invested in the portfolio securities involved during the term of the reverse repurchase agreement, while in many cases the Fund is able to keep some of the interest income associated with those securities. Such transactions are advantageous only if each Underlying Fund has an opportunity to earn a rate of interest on the cash derived from these transactions that is greater than the interest cost of obtaining the same amount of cash. Opportunities to realize earnings from the use of the proceeds equal to or greater than the interest required to be paid may not always be available and each Underlying Fund intends to use the reverse repurchase technique only when BFA believes it will be advantageous to the Fund. The use of reverse repurchase agreements may exaggerate any interim increase or decrease in the value of each Underlying Fund’s assets. The Fund’s exposure to reverse repurchase agreements will be covered by liquid assets having a value equal to or greater than such commitments.

Securities of Investment Companies. The Fund may invest in the securities of other investment companies (including money market funds) and real estate investment trusts (“REITs”) to the extent allowed by law. Pursuant to the 1940 Act, the Fund’s investment in registered investment companies is limited to, subject to certain exceptions: (i) 3% of the total outstanding voting stock of any one investment company; (ii) 5% of the Fund’s total assets with respect to any one investment company; and (iii) 10% of the Fund’s total assets with respect to investment companies in the aggregate. To the extent allowed by law or regulation, the Fund may invest its assets in the securities of investment companies that are money market funds, including those advised by or otherwise affiliated with BFA, in excess of the limits discussed above. Other investment companies in which the Fund may invest can be expected to incur fees and expenses for operations, such as investment advisory and administration fees, which would be in addition to those incurred by the Fund. The Fund does not intend to invest more than 5% of its total assets in investment companies.

Short-Term Instruments and Temporary Investments. The Fund may invest in short-term instruments, including money market instruments, on an ongoing basis to provide liquidity or for other reasons. Money market instruments are generally short-term investments that may include but are not limited to: (i) shares of money market funds (including those advised by BFA or otherwise affiliated with BFA); (ii) obligations issued or guaranteed by the U.S. government, its agencies or instrumentalities (including government-sponsored enterprises); (iii) negotiable certificates of deposit (“CDs”), bankers’ acceptances, fixed-time deposits and other obligations of U.S. and non-U.S. banks (including non-U.S. branches) and similar institutions; (iv) commercial paper rated, at the date of purchase, “Prime-1” by Moody’s® Investors Service, Inc., “F-1” by Fitch Inc., or “A-1” by Standard & Poor’s® (a subsidiary of The McGraw-Hill Companies, Inc.) (“S&P® ”), or if unrated, of comparable quality as determined by BFA; (v) non-convertible corporate debt securities (e.g., bonds and debentures) with remaining maturities at the date of purchase of not more than 397 days and that satisfy the rating requirements set forth in Rule 2a-7 under the 1940 Act; (vi) repurchase agreements; and (vii) short-term U.S. dollar-denominated obligations of non-U.S. banks (including U.S. branches) that, in the opinion of BFA, are of comparable quality to obligations of U.S. banks which may be purchased by the Fund. Any of these instruments may be purchased on a current or forward-settled basis. Time deposits are non-negotiable deposits maintained in banking institutions for specified periods of time at stated interest rates. Bankers’ acceptances are time drafts drawn on commercial banks by borrowers, usually in connection with international transactions.

Swap Agreements. Swap agreements are contracts between parties in which one party agrees to make periodic payments to the other party based on the change in market value or level of a specified rate, index or asset. In return, the other party agrees to make periodic payments to the first party based on the return of a different specified rate, index or asset. Swap agreements will usually be performed on a net basis, with each Underlying Fund receiving or paying only the net amount of the two payments. The net amount of the excess, if any, of the Fund’s obligations over its entitlements with respect to each swap is accrued on a daily basis and an amount of liquid assets having an aggregate value at least equal to the accrued excess will be maintained by the Fund.

The use of interest rate and index swaps is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio security transactions. These transactions generally do not involve the delivery of securities or other underlying assets or principal.

Tracking Stocks. A tracking stock is a separate class of common stock whose value is linked to a specific business unit or operating division within a larger company and is designed to “track” the performance of such business unit or division. The tracking stock may pay dividends to shareholders independent of the parent company. The parent company, rather than the business unit or division, generally is the issuer of tracking stock. However, holders of the tracking stock may not have the same rights as holders of the company’s common stock.

Future Developments. The Board may, in the future, authorize each Underlying Fund to invest in securities contracts and investments, other than those listed in this SAI and in the Prospectus, provided they are consistent with each Underlying Fund’s investment objective and do not violate any investment restrictions or policies.

General Considerations and Risks

A discussion of some of the principal risks associated with an investment in the Fund is contained in the Prospectus.

An investment in the Fund should be made with an understanding that the value of the Fund’s portfolio securities may fluctuate in accordance with changes in the financial condition of the issuers of the portfolio securities, the value of stocks in general, and other factors that affect the market.

Dividend Risk. There is no guarantee that the issuer of the stocks held by the Fund will declare dividends in the future or that if declared, they will either remain at current levels or increase over time.

Risks of Derivatives. A derivative is a financial contract, the value of which depends on, or is derived from, the value of an underlying asset such as a security or an index. The Fund may invest in stock index futures contracts and other derivatives. Compared to conventional securities, derivatives can be more sensitive to changes in interest rates or to sudden fluctuations in market prices and thus the Fund’s losses may be greater if it invests in derivatives than if it invests only in conventional securities. Derivatives are also subject to counterparty risk, which is the risk that the other party in the transaction will not fulfill its contractual obligations.

Risks of Equity Securities. An investment in the Fund should be made with an understanding of the risks inherent in an investment in equity securities, including the risk that the financial condition of issuers may become impaired or that the general condition of stock markets may deteriorate (either of which may cause a decrease in the value of the portfolio securities and thus in the value of shares of the Fund). Common stocks are susceptible to general stock market fluctuations and to increases and decreases in value as market confidence and perceptions of their issuers change. These investor perceptions are based on various and unpredictable factors, including expectations regarding government, economic, monetary and fiscal policies, inflation and interest rates, economic expansion or contraction, and global or regional political, economic or banking crises. Holders of common stocks incur more risks than holders of preferred stocks and debt obligations because common stockholders generally have rights to receive payments from stock issuers that are inferior to the rights of creditors, or holders of debt obligations or preferred stocks. Further, unlike debt securities, which typically have a stated principal amount payable at maturity (the value of which, however, is subject to market fluctuations prior to maturity), or preferred stocks, which typically have a liquidation preference and which may have stated optional or mandatory redemption provisions, common stocks have neither a fixed principal amount nor a maturity.

Although most of the securities in the Underlying Index are listed on a national securities exchange, the principal trading market for some of the securities may be in the over-the-counter market. The existence of a liquid trading market for certain securities may depend on whether dealers will make a market in such securities. There can be no assurance that a market will be made or maintained or that any such market will be or remain liquid. The price at which securities may be sold and the value of the Fund’s shares will be adversely affected if trading markets for the Fund’s portfolio securities are limited or absent, or if bid/ask spreads are wide.

Risks of Futures and Options Transactions. There are several risks accompanying the utilization of futures contracts and options on futures contracts. First, a position in futures contracts and options on futures contracts may be closed only on the exchange on which the contract was made (or a linked exchange). While the Fund plans to utilize futures contracts only if an

active market exists for such contracts, there is no guarantee that a liquid market will exist for the contract at a specified time. Furthermore, because, by definition, futures contracts project price levels in the future and not current levels of valuation, market circumstances may result in a discrepancy between the price of the stock index future and the movement in the Fund’s Underlying Index. In the event of adverse price movements, the Fund would continue to be required to make daily cash payments to maintain its required margin. In such situations, if the Fund has insufficient cash, it may have to sell portfolio securities to meet daily margin requirements at a time when it may be disadvantageous to do so. In addition, the Fund may be required to deliver the instruments underlying the future contracts it has sold.

The risk of loss in trading futures contracts or uncovered call options in some strategies (e.g., selling uncovered stock index futures contracts) is potentially unlimited. The Fund does not plan to use futures and options contracts in this way. The risk of a futures position may still be large as traditionally measured due to the low margin deposits required. In many cases, a relatively small price movement in a futures contract may result in immediate and substantial loss or gain to the investor relative to the size of a required margin deposit. The Fund, however, intends to utilize futures and options contracts in a manner designed to limit the risk exposure to levels comparable to a direct investment in the types of stocks in which it invests.

Utilization of futures and options on futures by the Fund involves the risk of imperfect or even negative correlation to the Underlying Index if the index underlying the futures contract differs from the Underlying Index. There is also the risk of loss by the Fund of margin deposits in the event of bankruptcy of a broker with whom the Fund has an open position in the futures contract or option. The purchase of put or call options will be based upon predictions by BFA as to anticipated trends, which predictions could prove to be incorrect.

Because the futures market generally imposes less burdensome margin requirements than the securities market, an increased amount of participation by speculators in the futures market could result in price fluctuations. Certain financial futures exchanges limit the amount of fluctuation permitted in futures contract prices during a single trading day. The daily limit establishes the maximum amount by which the price of a futures contract may vary either up or down from the previous day’s settlement price at the end of a trading session. Once the daily limit has been reached in a particular type of contract, no trades may be made on that day at a price beyond that limit. It is possible that futures contract prices could move to the daily limit for several consecutive trading days with little or no trading, thereby preventing prompt liquidation of futures positions and subjecting the Fund to substantial losses. In the event of adverse price movements, the Fund would be required to make daily cash payments of variation margin.

Risks of Investing in Asia. Investments in securities of issuers in certain Asian countries involve risks not typically associated with investments in securities of issuers in more developed countries. Such heightened risks include, among others, expropriation and/or nationalization of assets, confiscatory taxation, political instability, including authoritarian and/or military involvement in governmental decision-making, armed conflict and social instability as a result of religious, ethnic and/or socio-economic unrest.

Certain Asian countries have democracies with relatively short histories, which may increase the risk of political instability. These countries have faced political and military unrest, and further unrest could present a risk to their local economies and securities markets. Indonesia and the Philippines have each experienced violence and terrorism, which has negatively impacted their economies. North and South Korea each have substantial military capabilities, and historical tensions between the two countries present the risk of war. Any outbreak of hostilities between the two countries could have a severe adverse effect on the South Korean economy and securities market. Increased political and social unrest in these geographic areas could adversely affect the performance of investments in this region.

Certain governments in this region administer prices on several basic goods, including fuel and electricity, within their respective countries. Certain governments may exercise substantial influence over many aspects of the private sector in their respective countries and may own or control many companies. Future government actions could have a significant effect on the economic conditions in this region, which in turn could have a negative impact on private sector companies. There is also the possibility of diplomatic developments adversely affecting investments in the region.

Corruption and the perceived lack of a rule of law in dealings with international companies in certain Asian countries may discourage foreign investment and could negatively impact the long-term growth of certain economies in this region. In addition, certain countries in the region are experiencing high unemployment and corruption, and have fragile banking sectors.

Some economies in this region are dependent on a range of commodities, including oil, natural gas and coal. Accordingly, they are strongly affected by international commodity prices and particularly vulnerable to any weakening in global demand for these products. The market for securities in this region may also be directly influenced by the flow of international capital, and by the economic and market conditions of neighboring countries. Adverse economic conditions or developments in neighboring countries may increase investors’ perception of the risk of investing in the region as a whole, which may adversely impact the market value of the securities issued by companies in the region.

Risks of Investing in Australasia. The economies of Australasia, which include Australia and New Zealand, are dependent on exports from the agricultural and mining sectors. This makes Australasian economies susceptible to fluctuations in the commodity markets. Australasian economies are also increasingly dependent on their growing service industries. Because the economies of Australasia are dependent on the economies of Asia, Europe and the United States as key trading partners and investors, reduction in spending by any of these trading partners on Australasian products and services, or negative changes in any of these economies, may cause an adverse impact on some or all of the Australasian economies. Additionally, Australia and New Zealand are located in a region that has historically been prone to natural disasters. Any natural disaster in the region could negatively impact the economies of Australia and New Zealand and affect the value of securities held by the Fund.

Risks of Investing in Europe. The Economic and Monetary Union of the European Union (the “EU”) requires member countries to comply with restrictions on inflation rates, deficits, interest rates, debt levels and fiscal and monetary controls, each of which may significantly affect every country in Europe. Decreasing imports or exports, changes in governmental or EU regulations on trade, changes in the exchange rate of the euro, the default or threat of default by an EU member country on its sovereign debt, and/or an economic recession in an EU member country may have a significant adverse effect on the economies of EU member countries and their trading partners. The European financial markets have recently experienced volatility and adverse trends due to concerns about economic downturns, rising government debt levels and the possible default of government debt in several European countries, including Greece, Ireland, Italy, Portugal and Spain. A default or debt restructuring by any European country would adversely impact holders of that country’s debt and sellers of credit default swaps linked to that country’s creditworthiness, which may be located in countries other than those listed in the previous sentence. These events have adversely affected the value and exchange rate of the euro and may continue to significantly affect the economies of every country in Europe, including countries that do not use the euro and non-EU member countries.

Risks of Investing in Non-U.S. Equity Securities. An investment in the Fund involves risks similar to those of investing in portfolios of equity securities traded on non-U.S. exchanges. These risks include market fluctuations caused by such factors as economic and political developments, changes in interest rates and perceived trends in stock prices. Investing in securities issued by issuers domiciled in countries other than the domicile of the investor and denominated in currencies other than an investor’s local currency entails certain considerations and risks not typically encountered by the investor in making investments in its home country and in that country’s currency. These considerations include favorable or unfavorable changes in interest rates, currency exchange rates, exchange control regulations and the costs that may be incurred in connection with conversions between various currencies. Investing in the Fund also involves certain risks and considerations not typically associated with investing in a fund whose portfolio contains exclusively securities of U.S. issuers. These risks include generally less liquid and less efficient securities markets; generally greater price volatility; less publicly available information about issuers; the imposition of withholding or other taxes; the imposition of restrictions on the expatriation of funds or other assets of the Fund; higher transaction and custody costs; delays and risks attendant in settlement procedures; difficulties in enforcing contractual obligations; lower liquidity and significantly smaller market capitalization; different accounting and disclosure standards; lower levels of regulation of the securities markets; more substantial government interference with the economy; higher rates of inflation; greater social, economic, and political uncertainty; the risk of nationalization or expropriation of assets; and the risk of war.

Risks of Investing in North America. The United States is Canada’s and Mexico’s largest trading and investment partner. The Canadian and Mexican economies are significantly affected by developments in the U.S. economy. Since the implementation of the North American Free Trade Agreement (“NAFTA”) in 1994 among Canada, the United States and Mexico, total merchandise trade between the three countries have increased. To further this relationship, the three NAFTA countries entered into the Security and Prosperity Partnership of North America in March 2005, which may further affect Canada’s and Mexico’s dependency on the U.S. economy. Economic events in any one North American country can have a significant economic effect on the entire North American region, and on some or all of the North American countries in which the Fund invests.

Risks of Investing in the Consumer Discretionary Sector. Companies engaged in the design, production or distribution of products or services for the consumer discretionary sector (including, without limitation, television and radio broadcasting, manufacturing, publishing, recording and musical instruments, motion pictures, photography, amusement and theme parks, gaming casinos, sporting goods and sports arenas, camping and recreational equipment, toys and games, apparel, travel-related services, automobiles, hotels and motels, and fast food and other restaurants) are subject to the risk that their products or services may become obsolete quickly. The consumer discretionary sector can be significantly affected by several factors, including, without limitation, the performance of domestic and international economies, exchange rates, changing consumer tastes and trends, marketing campaigns, cyclical revenue generation, consumer confidence, commodity price volatility, labor relations, interest rates, import and export controls, intense competition, technological developments and government regulation.

Risks of Investing in the Consumer Staples Sector. Companies in the consumer staples sector may be adversely affected by changes in the global economy, consumer spending, competition, demographics and consumer preferences, and production spending. Companies in the consumers staples sector are also affected by changes in government regulation, global economic, environmental and political events, economic conditions and the depletion of resources. In addition, companies in the consumers staples sector may be subject to risks pertaining to the supply of, demand for and prices of raw materials. The prices of raw materials fluctuate in response to a number of factors, including, without limitation, changes in government agricultural support programs, exchange rates, import and export controls, changes in international agricultural and trading policies, and seasonal and weather conditions.

Risks of Investing in the Energy Sector. Companies in the energy sector are strongly affected by the levels and volatility of global energy prices, energy supply and demand, government regulations and policies, energy production and conservation, efforts and technological change. Prices and supplies of energy may fluctuate significantly over short and long periods of time due to national and international political changes, Organization of Petroleum Exporting Countries (“OPEC”) policies, changes in relationships among OPEC members and between OPEC and oil-importing nations, the regulatory environment, taxation policies, and the economy of the key energy-consuming countries. In addition, companies in the energy sector are at risk of civil liability from accidents resulting in injury, loss of life or property, pollution or other environmental damage claims and risk of loss from terrorism and natural disasters. Disruptions in the oil industry or shifts in fuel consumption may significantly impact companies in this sector. In addition, because a significant portion of revenues of companies in this sector are derived from a relatively small number of customers that are largely composed of governmental entities and utilities, governmental budget constraints may have a significant impact on the stock prices of companies in this industry.

Risks of Investing in the Financial Sector. Companies in the financial sector include regional and money center banks, securities brokerage firms, asset management companies, savings banks and thrift institutions, specialty finance companies (e.g., credit card, mortgage providers), insurance and insurance brokerage firms, financial conglomerates and foreign banking and financial companies. The global financial markets have recently experienced very difficult conditions and volatility as well as significant adverse trends. The deteriorating conditions in these markets have resulted in a decrease in availability of corporate credit, capital and liquidity and have led indirectly to the insolvency, closure or acquisition of a number of financial institutions. These conditions have also contributed to consolidation within the financial industry. In addition, the global financial industry has been materially and adversely affected by a significant decline in the value of mortgage-backed and asset-backed securities, and by the sovereign debt crisis. The prospects of many financial companies are questionable and continue to evolve as financial companies revise their outlooks and write down assets that they hold.

Most financial companies are subject to extensive governmental regulation, which limits their activities and may affect their ability to earn a profit from a given line of business. Government regulation may change frequently and may have significant adverse consequences for companies in the financial sector, including effects not intended by the regulation. Direct governmental intervention in the operations of financial companies and financial markets may materially and adversely affect the companies in which the Fund invests, including recent legislation in many countries that may increase government regulation, repatriation and other intervention. The impact of governmental intervention and recent legislation on any individual financial company or on the financial sector as a whole cannot be predicted. The valuation of financial companies has been and continues to be subject to unprecedented volatility and may be influenced by unpredictable factors, including interest rate risk and sovereign debt default. Certain financial businesses are subject to intense competitive pressures, including market share and price competition. Financial companies in foreign countries are subject to market specific and general regulatory and interest rate concerns. In particular, government regulation in certain foreign countries may include taxes and controls on interest rates, credit availability, minimum capital requirements, ban on short sales, prices and currency transfers.

The profitability of banks, savings and loan associations and financial companies is largely dependent on the availability and cost of capital funds and can fluctuate significantly when interest rates change. In addition, general economic conditions are important to the operations of these concerns, with exposure to credit losses resulting from financial difficulties of borrowers having an adverse effect on the profitability of financial companies. Financial companies can be highly dependent upon access to capital markets and any impediments to such access, such as adverse overall economic conditions or a negative perception in the capital markets of a financial company’s financial condition or prospects, could adversely affect its business.

Risks of Investing in the Health Care Sector. Companies in the health care sector are often issuers whose profitability may be affected by extensive government regulation, restrictions on government reimbursement for medical expenses, rising or falling costs of medical products and services, pricing pressure, an increased emphasis on outpatient services, limited number of products, industry innovation, changes in technologies and other market developments. Many health care companies are heavily dependent on patent protection and the actual or perceived safety and efficiency of their products. The expiration of patents may adversely affect the profitability of these companies. Many health care companies are subject to extensive litigation based on product liability and similar claims. Health care companies are subject to competitive forces that may make it difficult to raise prices and, in fact, may result in price discounting. Many new products in the health care sector may be subject to regulatory approvals. The process of obtaining such approvals may be long and costly, and may diminish the opportunity for a company to profit from a new product or to bring a new product to market. Many health care-related companies are relatively small and unseasoned. Health care companies may also be strongly affected by scientific bio-technology or technological developments and their products may quickly become obsolete. Also, many health care companies offer products and services that are subject to governmental regulation and may be adversely affected by changes in governmental policies or laws. The impact of recent legislation passed by the U.S. government and other legislation introduced or considered by other governments on any individual health care company or on the health care sector as a whole cannot be predicted. These laws and proposals span a wide range of topics, including cost control, national health insurance, incentives for compensation in the provision of health care services, tax incentives and penalties related to health care insurance premiums, and promotion of prepaid health care plans. No one can predict what proposals will be enacted or what potentially adverse effect they may have on health care-related or biotechnology-related companies.

Risks of Investing in the Industrials Sector. The stock prices of companies in the industrials sector are affected by supply and demand both for their specific product or service and for industrials sector products in general. The products of manufacturing companies may face product obsolescence due to rapid technological developments and frequent new product introduction. Government regulations, world events and economic conditions affect the performance of companies in the industrials sector. Companies in the industrials sector may be adversely affected by liability for environmental damage, product liability claims and exchange rates. The industrials sector may also be adversely affected by changes or trends in commodity prices, which may be influenced by unpredictable factors.

Risks of Investing in the Information Technology Sector. Information technology companies face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Like other technology companies, information technology companies may have limited product lines, markets, financial resources or personnel. The products of information technology companies may face product obsolescence due to rapid technological developments and frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Companies in the information technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies.

Risks of Investing in the Materials Sector. Companies in the materials sector could be adversely affected by commodity price volatility, exchange rates, import controls, increased competition, depletion of resources, technical progress, labor relations, exchange rates and government regulations, among other factors. Also, companies in the materials sector are at risk of liability for environmental damage and product liability claims. Production of materials may exceed demand as a result of market imbalances or economic downturns, leading to poor investment returns.

Risks of Investing in the Technology Sector. Technology companies face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Technology companies may have limited product lines, markets, financial resources or personnel. The products of technology companies may face product obsolescence due to rapid technological developments and frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Companies in the technology sector are heavily dependent on patent and

intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies. The technology sector may also be adversely affected by changes or trends in commodity prices, which may be influenced or characterized by unpredictable factors.

Risks of Investing in the Telecommunications Sector. The telecommunications sector of an economy is often subject to extensive government regulation. The costs of complying with governmental regulations, delays or failure to receive required regulatory approvals or the enactment of new adverse regulatory requirements may adversely affect the business of the telecommunications companies. Government actions around the world, specifically in the area of pre-marketing clearance of products and prices, can be arbitrary and unpredictable. Companies in the telecommunications sector may encounter distressed cash flows due to the need to commit substantial capital to meet increasing competition, particularly in formulating new products and services using new technology. Technological innovations may make the products and services of telecommunications companies obsolete.

Risks of Investing in the Utilities Sector. Investments in utility companies involve special considerations, including the risk of changing commodity prices, government regulation stipulating rates charged by utilities, increased tariffs, changes in tax laws, interest rate fluctuations and changes in the cost of providing the specific utility services. The utilities industry is also subject to potential terrorist attacks, natural disasters and severe weather conditions, as well as regulatory and operational burdens associated with the operation and maintenance of nuclear facilities. Government regulators monitor and control utility revenues and costs, and therefore may limit utility profits. In certain countries regulatory authorities may also restrict a company’s access to new markets, thereby diminishing a company’s long-term prospects. The deregulation of certain utilities companies may eliminate restrictions on profits but may also subject these companies to greater risks of loss.

Risks of Swap Agreements. The risk of loss with respect to swaps generally is limited to the net amount of payments that the Fund is contractually obligated to make. Swap agreements are subject to the risk that the swap counterparty will default on its obligations. If such a default occurs, the Fund will have contractual remedies pursuant to the agreements related to the transaction. However, such remedies may be subject to bankruptcy and insolvency laws which could affect the Fund’s rights as a creditor (e.g., the Fund may not receive the net amount of payments that it is contractually entitled to receive).

Proxy Voting Policy

The Trust has adopted, as its proxy voting policies for the Fund, the proxy voting guidelines of BFA, the investment adviser to the Fund. The Trust has delegated to BFA the responsibility for voting proxies on the portfolio securities held by the Fund. The remainder of this section discusses the Fund’s proxy voting guidelines and BFA’s role in implementing such guidelines.

BFA votes (or refrains from voting) proxies for the Fund in a manner that BFA, in the exercise of its independent business judgment, concludes is in the best economic interests of the Fund. In some cases, BFA may determine that it is in the best economic interests of the Fund to refrain from exercising the Fund’s proxy voting rights (such as, for example, proxies on certain non-U.S. securities that might impose costly or time-consuming in-person voting requirements). With regard to the relationship between securities lending and proxy voting, BFA’s approach is also driven by the Fund’s economic interests. The evaluation of the economic desirability of recalling loans involves balancing the revenue-producing value of loans against the likely economic value of casting votes. Based on our evaluation of this relationship, we believe that the likely economic value of casting a vote generally is less than the securities lending income, either because the votes will not have significant economic consequences or because the outcome of the vote would not be affected by BFA recalling loaned securities in order to ensure they are voted. Periodically, BFA analyzes the process and benefits of voting proxies for securities on loan, and will consider whether any modification of its proxy voting policies or procedures are necessary in light of any regulatory changes. BFA will normally vote on specific proxy issues in accordance with its proxy voting guidelines. BFA’s proxy voting guidelines provide detailed guidance as to how to vote proxies on certain important or commonly raised issues. BFA may, in the exercise of its business judgment, conclude that the proxy voting guidelines do not cover the specific matter upon which a proxy vote is requested, or that an exception to the proxy voting guidelines would be in the best economic interests of the Fund. BFA votes (or refrains from voting) proxies without regard to the relationship of the issuer of the proxy (or any shareholder of such issuer) to the Fund, the Fund’s affiliates (if any), BFA or BFA’s affiliates, or the Distributor or the Distributor’s affiliates. When voting proxies, BFA attempts to encourage issuers to follow practices that enhance shareholder value and increase transparency and allow the market to place a proper value on their assets. With respect to certain specific issues:

  • The Fund generally supports the board’s nominees in the election of directors and generally supports proposals that strengthen the independence of boards of directors;
  • The Fund generally does not support proposals on social issues that lack a demonstrable economic benefit to the issuer and the Fund investing in such issuer; and
  • The Fund generally votes against anti-takeover proposals and proposals that would create additional barriers or costs to corporate transactions that are likely to deliver a premium to shareholders.

BFA maintains institutional policies and procedures that are designed to prevent any relationship between the issuer of the proxy (or any shareholder of the issuer) and the Fund, the Fund’s affiliates (if any), BFA or BFA’s affiliates (if any) or the Distributor or the Distributor’s affiliates, from having undue influence on BFA’s proxy voting activity. In certain instances, BFA may determine to engage an independent fiduciary to vote proxies as a further safeguard against potential conflicts of interest or as otherwise required by applicable law. The independent fiduciary may either vote such proxies or provide BFA with instructions as to how to vote such proxies. In the latter case, BFA votes the proxy in accordance with the independent fiduciary’s determination.

Information with respect to how BFA voted proxies relating to the Fund’s portfolio securities during the 12-month period ending June 30 is available: (i) without charge, upon request, by calling 1-800-iShares (1-800-474-2737) or through the Fund’s website at www.iShares.com; and (ii) on the SEC’s website at www.sec.gov.

Portfolio Holdings Information

The Board has adopted a policy regarding the disclosure of the Fund’s portfolio holdings information that requires that such information be disclosed in a manner that: (i) is consistent with applicable legal requirements and in the best interests of the Fund’s shareholders; (ii) does not put the interests of BFA, the Distributor or any affiliated person of BFA or the Distributor, above those of Fund shareholders; (iii) does not advantage any current or prospective Fund shareholders over any other current or prospective Fund shareholders, except to the extent that certain Entities (as described below) may receive portfolio holdings information not available to other current or prospective Fund shareholders in connection with the dissemination of information necessary for transactions in Creation Units, as contemplated by the iShares Exemptive Orders and as discussed below; and (iv) does not provide selective access to portfolio holdings information except pursuant to the procedures outlined below and to the extent appropriate confidentiality arrangements limiting the use of such information are in effect. The “Entities” referred to in sub-section (iii) above are generally limited to National Securities Clearing Corporation (“NSCC”) members, subscribers to various fee-based subscription services, large institutional investors (known as “Authorized Participants”) that have been authorized by the Distributor to purchase and redeem large blocks of shares pursuant to legal requirements, including exemptive orders granted by the SEC pursuant to which the Fund offers and redeems its shares (“iShares Exemptive Orders”) and other institutional market participants and entities that provide information services.

Each business day, the Fund’s portfolio holdings information is provided to the Distributor or other agent for dissemination through the facilities of the NSCC and/or other fee-based subscription services to NSCC members and/or subscribers to those other fee-based subscription services, including Authorized Participants, and to entities that publish and/or analyze such information in connection with the process of purchasing or redeeming Creation Units or trading shares of the Fund in the secondary market. This information typically reflects the Fund’s anticipated holdings on the following business day.

Daily access to information concerning the Fund’s portfolio holdings is permitted (i) to certain personnel of those service providers that are involved in portfolio management and providing administrative, operational, risk management, or other support to portfolio management, including affiliated broker-dealers and Authorized Participants; and (ii) to other personnel of the Fund’s investment adviser and the Distributor, administrator, custodian and fund accountant who deal directly with or assist in, functions related to investment management, distribution, administration, custody and fund accounting, as may be necessary to conduct business in the ordinary course in a manner consistent with the iShares Exemptive Orders, agreements with the Fund and the terms of the Fund’s current registration statement. In addition, the Fund discloses its portfolio holdings and the percentages they represent of the Fund’s net assets at least monthly, and as often as each day the Fund is open for business, at www.iShares.com. More information about this disclosure is available at www.iShares.com.

Portfolio holdings information made available in connection with the creation/redemption process may be provided to other entities that provide services to the Fund in the ordinary course of business after it has been disseminated to the NSCC. From time to time, information concerning portfolio holdings other than portfolio holdings information made available in

connection with the creation/redemption process, as discussed above, may be provided to other entities that provide services to the Fund, including rating or ranking organizations, in the ordinary course of business, no earlier than one business day following the date of the information.

The Fund discloses its complete portfolio holdings schedule in public filings with the SEC within 70 days after the end of each fiscal quarter and will provide that information to shareholders as required by federal securities laws and regulations thereunder. The Fund may, however, voluntarily disclose all or part of its portfolio holdings other than in connection with the creation/redemption process, as discussed above, in advance of required filings with the SEC, provided that such information is made generally available to all shareholders and other interested parties in a manner that is consistent with the above policy for disclosure of portfolio holdings information. Such information may be made available through a publicly-available website or other means that make the information available to all likely interested parties contemporaneously.

The Trust’s Chief Compliance Officer may authorize disclosure of portfolio holdings information pursuant to the above policy and procedures.

The Board reviews the policy and procedures for disclosure of portfolio holdings information at least annually.

Construction and Maintenance of the Underlying Index

A description of the Underlying Index is provided below.

The MSCI Indexes

The MSCI indexes were founded in 1969 by Capital International S.A. as the first international performance benchmarks constructed to facilitate accurate comparison of world markets. The MSCI single country standard equity indexes have covered the world’s developed markets since 1969 and in 1987 MSCI commenced coverage of emerging markets.

Local stock exchanges traditionally calculated their own indexes, which were generally not comparable with one another due to differences in the representation of the local market, mathematical formulas, base dates and methods of adjusting for capital changes. MSCI, however, applies the same calculation methodology to all markets for all single country standard equity indexes, both developed and emerging.

MSCI’s Global Investable Market Indexes (the “MSCI GIMI”) provide exhaustive coverage and non-overlapping market segmentation by market capitalization size and by style. The MSCI GIMI intends to target approximately 99% coverage of the free-float adjusted market capitalization in each market of large, mid and small cap securities.

  • MSCI Global Standard Indexes cover all investable large and mid cap securities by including approximately 85% of each market’s free-float adjusted market capitalization.
  • MSCI Global Small Cap Indexes provide coverage to all companies with a market capitalization below that of the companies in the MSCI Global Standard Indexes by including above and beyond the coverage of the MSCI Global Standard Indexes.

MSCI Global Investable Market Indexes

Selection Criteria. MSCI’s index construction process involves: (i) defining the equity universe; (ii) determining the market investable equity universe for each market; (iii) determining market capitalization size segments for each market; (iv) applying final size segment investability requirements; and (v) applying index continuity rules for the MSCI Global Standard Index.

Defining the Equity Universe. MSCI begins with securities listed in countries in the MSCI GIMI. Of these countries, as of August 31, 2011, 24 are classified as developed markets, 21 as emerging markets, and 31 as frontier markets. All listed equity securities and listed securities that exhibit characteristics of equity securities, except mutual funds, exchange traded funds, equity derivatives, limited partnerships and most investment trusts, are eligible for inclusion in the equity universe. REITs in

some countries and certain income trusts in Canada are also eligible for inclusion. Each company and its securities (i.e., share classes) are classified in only one country.

Determining the Market Investable Equity Universe for each Market. The equity universe in any market is derived by applying investability screens to individual companies and securities in the equity universe of that market. Some investability requirements are applied at the individual security level and some at the overall company level, represented by the aggregation of individual securities of the company. As a result, the inclusion or exclusion of one security does not imply the automatic inclusion or exclusion of other securities of the same company.

Determining Market Capitalization Size Segments for each Market. In each market, MSCI creates an Investable Market Index, Standard Index, Large Cap Index, Mid Cap Index and Small Cap Index. The MSCI Global Standard Index is the aggregation of the Large Cap Index and Mid Cap Index. The MSCI GIMI is the aggregation of the MSCI Global Standard Index and MSCI Global Small Cap Index. In order to create size components that can be meaningfully aggregated into composites, individual market size segments balance the following two objectives:

  • Achieving global size integrity by ensuring that companies of comparable and relevant sizes are included in a given size segment across all markets in a composite index; and
  • Achieving consistent market coverage by ensuring that each market’s size segment is represented in its proportional weight in the composite universe.

Applying Final Size Segment Investability Requirements. In order to enhance replicability of the indexes, additional size segment investability requirements are set for the MSCI GIMI and MSCI Global Standard Index. These investability requirements include minimum free float market capitalization, minimum liquidity, minimum foreign limits and minimum length of trading.

Applying Index Continuity Rules for the Standard Index. In order to achieve index continuity as well as provide some basic level of diversification within a market index, notwithstanding the effect of other index construction rules contained herein, a minimum number of five constituents will be maintained for a developed market Standard Index and a minimum number of three constituents will be maintained for an emerging market Standard Index.

Weighting. All indexes of the MSCI GIMI are free-float weighted, i.e., companies are included in the indexes at the value of their free public float (free float multiplied by security price).

Regional Weights. Market capitalization weighting, combined with a consistent target of approximately 99% of free-float adjusted market capitalization, helps ensure that each country’s weight in regional and international indexes approximates its weight in the total universe of developing and emerging markets. A market is equivalent to a single country except for Europe, where all markets are aggregated into a single market for index construction purposes. Individual country indexes of the European developed markets are derived from the constituents of the MSCI GIMI Europe Index.

Free Float. MSCI defines the free float of a security as the proportion of shares outstanding that are deemed to be available for purchase in the public equity markets by international investors. In practice, limitations on free float available to international investors include: (i) strategic and other shareholdings not considered part of available free float; and (ii) limits on share ownership for foreigners.

Under MSCI’s free-float adjustment methodology, a constituent’s inclusion factor is equal to its estimated free float rounded-up to the closest 5% for constituents with free float equal to or exceeding 15%. For example, a constituent security with a free float of 23.2% will be included in the index at 25% of its market capitalization. For securities with a free float of less than 15%, the estimated free float is adjusted to the nearest 1%.

Price and Exchange Rates

Prices. The prices used to calculate all MSCI indexes are the official exchange closing prices or those figures accepted as such. MSCI reserves the right to use an alternative pricing source on any given day.

Exchange Rates. Since July 2000, MSCI uses the WM/Reuters Closing Spot Rates taken at 4:00 p.m. London time. In case WM/Reuters does not provide rates for specific markets on given days (for example, Christmas Day and New Year’s Day), the previous business day’s rates are normally used. MSCI independently monitors the exchange rates on all its indices. MSCI may under exceptional circumstances elect to use alternative sources of exchange rates if the WM/Reuters rates are not

available, or if MSCI determines that the WM/Reuters rates are not reflective of market circumstances for a given currency on a particular day. In such circumstances, an announcement would be sent to clients with the related information. If appropriate, MSCI may conduct a consultation with the investment community to gather feedback on the most relevant exchange rate.

Changes to the Indexes. The MSCI GIMI is maintained with the objective of reflecting, on a timely basis, the evolution of the underlying equity markets. In maintaining the MSCI indexes, emphasis is also placed on continuity, replicability and minimizing turnover in the indexes. Maintaining the MSCI indexes involves many aspects, including (i) additions to, and deletions from, the indexes; (ii) changes in number of shares; and (iii) changes in inclusion factors as a result of updated free float estimates.

Index maintenance can be described by three broad categories of changes:

  • Semi-Annual Index Reviews (“SAIRs”), conducted on a fixed semi-annual timetable that systematically reassess the various dimensions of the equity universe for all markets;
  • Quarterly Index Reviews (“QIRs”), aimed at promptly reflecting other significant market events; and
  • Ongoing event-related changes, such as mergers, acquisitions, spin-offs, bankruptcies, reorganizations and other similar corporate events, which generally are implemented in the indexes as they occur.

Potential changes in the status of countries (stand-alone, frontier, emerging and developed) follow their own implementation time tables.

MSCI conducts SAIRs generally as of the close of the last business day of May and November. During the SAIRs, MSCI updates the investable equity universe and reassesses size segmentation investability requirements. MSCI also conducts QIRs generally as of the close of the last business day of February and August. During the QIRs, MSCI reflects changes in the index that were not captured at the time of their actual occurrence, but are significant enough to be included before the next SAIR. The results of the SAIR and QIR are generally announced at least ten business days in advance of implementation.

MSCI Kokusai Index

The Fund is not sponsored, endorsed, sold or promoted by MSCI Inc. Nor does MSCI Inc. make any representation regarding the advisability of investing in the Fund.

Investment Limitations

The Fund has adopted its investment objective as a non-fundamental investment policy. Therefore, the Fund may change its investment objective and its Underlying Index without shareholder approval. The Board has adopted as fundamental policies the following numbered investment restrictions, which cannot be changed without the approval of the holders of a majority of the Fund’s outstanding voting securities. A vote of a majority of the outstanding voting securities is defined in the 1940 Act as the lesser of (a) 67% or more of the voting securities present at a fund meeting, if the holders of more than 50% of the outstanding voting securities are present or represented by proxy and (b) more than 50% of outstanding voting securities of the fund.

The Fund will not:

1. Concentrate its investments (i.e., invest 25% or more of its total assets in the securities of a particular industry or group of industries), except that the Fund will concentrate to approximately the same extent that the Underlying Index concentrates in the securities of such particular industry or group of industries. For purposes of this limitation, securities of the U.S. government (including its agencies and instrumentalities), repurchase agreements collateralized by U.S. government securities, and securities of state or municipal governments and their political subdivisions are not considered to be issued by members of any industry.
2. Borrow money, except that (i) the Fund may borrow from banks for temporary or emergency (not leveraging) purposes,

including the meeting of redemption requests which might otherwise require the untimely disposition of securities; and (ii) the Fund may, to the extent consistent with its investment policies, enter into repurchase agreements, reverse repurchase agreements, forward roll transactions and similar investment strategies and techniques. To the extent that it engages in transactions described in (i) and (ii), the Fund will be limited so that no more than 33 1/3% of the value of its total assets (including the amount borrowed) is derived from such transactions. Any borrowings which come to exceed this amount will be reduced in accordance with applicable law.
3. Issue any senior security, except as permitted under the 1940 Act, as amended, and as interpreted, modified or otherwise permitted by regulatory authority having jurisdiction, from time to time.
4. Make loans, except as permitted under the 1940 Act, as interpreted, modified or otherwise permitted by regulatory authority having jurisdiction, from time to time.
5. Purchase or sell real estate unless acquired as a result of ownership of securities or other instruments (but this restriction shall not prevent the Fund from investing in securities of companies engaged in the real estate business or securities or other instruments backed by real estate or mortgages), or commodities or commodity contracts (but this restriction shall not prevent the Fund from trading in futures contracts and options on futures contracts, including options on currencies to the extent consistent with the Fund’s investment objective and policies).
6. Engage in the business of underwriting securities issued by other persons, except to the extent that the Fund may technically be deemed to be an underwriter under the 1933 Act, in disposing of portfolio securities.

In addition to the investment restrictions adopted as fundamental policies set forth above, the Fund has adopted a non-fundamental policy not to invest in the securities of a company for the purpose of exercising management or control or purchase or otherwise acquire any illiquid security, except as permitted under the 1940 Act, which currently permits up to 15% of the Fund’s net assets to be invested in illiquid securities (calculated at the time of investment).

BFA monitors the liquidity of restricted securities in the Fund’s portfolio. In reaching liquidity decisions, BFA considers the following factors:

  • The frequency of trades and quotes for the security;
  • The number of dealers wishing to purchase or sell the security and the number of other potential purchasers;
  • Dealer undertakings to make a market in the security; and
  • The nature of the security and the nature of the marketplace in which it trades (e.g., the time needed to dispose of the security, the method of soliciting offers and the mechanics of transfer).

If any percentage restriction described above is complied with at the time of an investment, a later increase or decrease in percentage resulting from a change in values of assets will not constitute a violation of such restriction, except that certain percentage limitations will be observed continuously in accordance with applicable law.

The Fund has adopted a non-fundamental investment policy in accordance with Rule 35d-1 under the 1940 Act to invest, under normal circumstances, at least 80% of the value of its net assets, plus the amount of any borrowings for investment purposes, in securities of the Underlying Index or in Depositary Receipts representing securities in the Underlying Index. The Fund also has adopted a policy to provide its shareholders with at least 60 days’ prior written notice of any change in such policy. If, subsequent to an investment, the 80% requirement is no longer met, the Fund’s future investments will be made in a manner that will bring the Fund into compliance with this policy.

Continuous Offering

The method by which Creation Units are created and traded may raise certain issues under applicable securities laws. Because new Creation Units are issued and sold by the Fund on an ongoing basis, at any point a “distribution,” as such term is used in the 1933 Act, may occur. Broker-dealers and other persons are cautioned that some activities on their part may, depending on the circumstances, result in their being deemed participants in a distribution in a manner that could render them statutory underwriters and subject them to the prospectus delivery requirement and liability provisions of the 1933 Act.

For example, a broker-dealer firm or its client may be deemed a statutory underwriter if it takes Creation Units after placing an order with the Distributor, breaks them down into constituent shares and sells such shares directly to customers or if it chooses to couple the creation of new shares with an active selling effort involving solicitation of secondary market demand

for shares. A determination of whether one is an underwriter for purposes of the 1933 Act must take into account all the facts and circumstances pertaining to the activities of the broker-dealer or its client in the particular case and the examples mentioned above should not be considered a complete description of all the activities that could lead to a categorization as an underwriter.

Broker-dealer firms should also note that dealers who are not “underwriters” but are effecting transactions in shares, whether or not participating in the distribution of shares, generally are required to deliver a prospectus. This is because the prospectus delivery exemption in Section 4(3) of the 1933 Act is not available in respect of such transactions as a result of Section 24(d) of the 1940 Act. Firms that incur a prospectus delivery obligation with respect to shares of the Fund are reminded that, pursuant to Rule 153 under the 1933 Act, a prospectus delivery obligation under Section 5(b)(2) of the 1933 Act owed to an exchange member in connection with a sale on the Listing Exchange is satisfied by the fact that the prospectus is available at the Listing Exchange upon request. The prospectus delivery mechanism provided in Rule 153 is available only with respect to transactions on an exchange.

Management

Trustees and Officers. The Board has responsibility for the overall management and operations of the Fund, including general supervision of the duties performed by BFA and other service providers. Each Trustee serves until he or she resigns, is removed, dies, retires or becomes incapacitated.

The Board has concluded that, based on each Trustee’s experience, qualifications, attributes or skills on an individual basis and in combination with those of the other Trustees, each Trustee should serve as a Trustee of the Board. Among the attributes common to all Trustees are their ability to review critically, evaluate, question and discuss information provided to them, to interact effectively with the Fund’s investment adviser, other service providers, counsel and the independent registered public accounting firm, and to exercise effective business judgment in the performance of their duties as Trustees. A Trustee’s ability to perform his or her duties effectively may have been attained through the Trustee’s educational background or professional training; business, consulting, public service or academic positions; experience from service as a board member of the Fund and the other funds in the Trust (and any predecessor funds), other investment funds, public companies, or non-profit entities or other organizations; and/or other life experiences.

Board – Leadership Structure and Oversight Responsibilities

Overall responsibility for oversight of the Fund rests with the Board. The Board has engaged BFA to manage the Fund on a day-to-day basis. The Board is responsible for overseeing BFA and other service providers in the operations of the Fund in accordance with the provisions of the 1940 Act, applicable provisions of state and other laws and the Trust’s charter. The Board is currently composed of nine members, seven of whom are Independent Trustees (defined below). The Board currently conducts regular meetings four times a year. In addition, the Board frequently holds special in-person or telephonic meetings or informal conference calls to discuss specific matters that may arise or require action between regular meetings. The Independent Trustees meet regularly outside the presence of management, in executive session or with other service providers to the Trust.

The Board has appointed an Independent Trustee to serve in the role of Chairman. The Chairman’s role is to preside at all meetings of the Board and to act as a liaison with service providers, officers, attorneys, and other Trustees generally between meetings. The Chairman may also perform such other functions as may be delegated by the Board from time to time. The Board has established a Nominating and Governance Committee and an Audit Committee to assist the Board in the oversight and direction of the business and affairs of the Fund, and from time to time may establish ad-hoc committees or informal

working groups to review and address the policies and practices of the Fund with respect to certain specified matters. The Board and each standing Committee conduct annual assessments of their oversight function and structure. The Board has determined that the Board’s leadership structure is appropriate because it allows the Board to exercise independent judgment over management and it allocates areas of responsibility among committees of Independent Trustees and the full Board to enhance effective oversight.

Day-to-day risk management with respect to the Fund is the responsibility of BFA or other service providers (depending on the nature of the risk), subject to the supervision of BFA. The Fund is subject to a number of risks, including investment, compliance, operational and valuation risks, among others. While there are a number of risk management functions performed by BFA and other service providers, as applicable, it is not possible to eliminate all of the risks applicable to the Fund. The Trustees have an oversight role in this area, satisfying themselves that risk management processes are in place and operating effectively. Risk oversight forms part of the Board’s general oversight of the Fund and is addressed as part of various Board and committee activities. The Board, directly or through a committee, also reviews reports from, among others, management and the independent registered public accounting firm for the Trust, as appropriate, regarding risks faced by the Fund and management’s risk functions. The Board has appointed a Chief Compliance Officer who oversees the implementation and testing of the Trust’s compliance program and reports to the Board regarding compliance matters for the Trust and its principal service providers. In testing and maintaining the compliance program, the Chief Compliance Officer assesses key compliance risks affecting the Fund, and addresses them in reports to the Board. The Independent Trustees have engaged independent legal counsel to assist them in performing their oversight responsibilities.

Committees of the Board of Trustees. Each Trustee who is not an interested person (as defined in the 1940 Act) of the Trust (“Independent Trustee”) serves on the Audit Committee and the Nominating and Governance Committee of the Board. The purposes of the Audit Committee are to assist the Board (i) in its oversight of the Trust’s accounting and financial reporting principles and policies and related controls and procedures maintained by or on behalf of the Trust; (ii) in its oversight of the Trust’s financial statements and the independent audit thereof; (iii) in selecting, evaluating and, where deemed appropriate, replacing the independent accountants (or nominating the independent accountants to be proposed for shareholder approval in any proxy statement); (iv) in evaluating the independence of the independent accountants; (v) in complying with legal and regulatory requirements that relate to the Trust’s accounting and financial reporting, internal controls and independent audits; and (vi) to assume such other responsibilities as may be delegated by the Board. The Audit Committee met five times during the fiscal year ended July 31, 2011.

The Nominating and Governance Committee nominates individuals for Independent Trustee membership on the Board. The Nominating and Governance Committee functions include, but are not limited to, the following: (i) reviewing the qualifications of any person properly identified or nominated to serve as an Independent Trustee; (ii) recommending to the Board and current Independent Trustees the nominee(s) for appointment as an Independent Trustee by the Board and current Independent Trustees and/or for election as Independent Trustees by shareholders to fill any vacancy for a position of Independent Trustee(s) on the Board; (iii) recommending to the Board and current Independent Trustees the size and composition of the Board and Board committees and whether they comply with applicable laws and regulations; (iv) recommending a current Independent Trustee to the Board and current Independent Trustees to serve as Lead Independent Trustee; (v) periodic review of the Board’s retirement policy; and (vi) recommending an appropriate level of compensation for the Independent Trustees for their services as Trustees, members or chairpersons of committees of the Board, Lead Independent Trustee, Chairperson of the Board and any other positions as the Nominating and Governance Committee considers appropriate. The Nominating and Governance Committee does not consider Board nomination(s) recommended by shareholders (acting solely in their capacity as a shareholder and not in any other capacity). The Nominating and Governance Committee is comprised of all members of the Board that are Independent Trustees. The Nominating and Governance Committee met five times during the fiscal year ended July 31, 2011.

Potential Conflicts of Interest. Barclays PLC (“Barclays”) and The PNC Financial Services Group, Inc. (“PNC”), each has a significant economic interest in BlackRock, Inc., the parent of BFA, the Fund’s investment adviser. PNC is considered to be an affiliate of BlackRock, Inc., under the 1940 Act. Certain activities of BlackRock Advisors, LLC, BlackRock, Inc. and their affiliates (collectively, “BlackRock”) and PNC and its affiliates (collectively, “PNC” and together with BlackRock, “Affiliates”), and those of Barclays and its affiliates (collectively, the “Barclays Entities”), with respect to the Fund and/or other accounts managed by BlackRock, PNC or Barclays Entities, may give rise to actual or perceived conflicts of interest such as those described below.

BlackRock is one of the world’s largest asset management firms. PNC is a diversified financial services organization spanning the retail, business and corporate markets. Barclays is a major global financial services provider engaged in a range of activities, including retail and commercial banking, credit cards, investment banking, and wealth management. BlackRock and PNC are affiliates of one another under the 1940 Act. BlackRock, PNC, Barclays and their respective affiliates (including, for these purposes, their directors, partners, trustees, managing members, officers and employees), including the entities and personnel who may be involved in the investment activities and business operations of the Fund, are engaged worldwide in businesses, including equity, fixed income, cash management and alternative investments. These are considerations of which investors in the Fund should be aware, and which may cause conflicts of interest that could disadvantage the Fund and its shareholders. These activities and interests include potential multiple advisory, transactional, financial and other interests in securities and other instruments that may be purchased or sold by the Fund.

BlackRock and its Affiliates, as well as the Barclays Entities, have proprietary interests in, and may manage or advise with respect to, accounts or funds (including separate accounts and other funds and collective investment vehicles) that have investment objectives similar to those of the Fund and/or that engage in transactions in the same types of securities, currencies and instruments as the Fund. One or more Affiliates and Barclays Entities are also major participants in the global currency, equities, swap and fixed income markets, in each case both on a proprietary basis and for the accounts of customers. As such, one or more Affiliates or Barclays Entities are or may be actively engaged in transactions in the same securities, currencies, and instruments in which the Fund invests. Such activities could affect the prices and availability of the securities, currencies, and instruments in which the Fund invests, which could have an adverse impact on the Fund’s performance. Such transactions, particularly in respect of most proprietary accounts or customer accounts, will be executed independently of the Fund’s transactions and thus at prices or rates that may be more or less favorable than those obtained by the Fund. When BlackRock and its Affiliates purchase or sell the same assets for their managed accounts, including the Fund, the assets actually purchased or sold may be allocated among the accounts on a basis determined in their good faith discretion to be equitable. In some cases, this system may adversely affect the size or price of the assets purchased or sold for the Fund. In addition, transactions in investments by one or more other accounts managed by BlackRock or its Affiliates or a Barclays Entity may have the effect of diluting or otherwise disadvantaging the values, prices or investment strategies of the Fund, particularly, but not limited to, with respect to small capitalization, emerging market or less liquid strategies. This may occur when investment decisions regarding the Fund are based on research or other information that is also used to support decisions for other accounts. When BlackRock or its Affiliates or a Barclays Entity implements a portfolio decision or strategy on behalf of another account ahead of, or contemporaneously with, similar decisions or strategies for the Fund, market impact, liquidity constraints, or other factors could result in the Fund receiving less favorable trading results and the costs of implementing such decisions or strategies could be increased or the Fund could otherwise be disadvantaged. BlackRock or its Affiliates or a Barclays Entity may, in certain cases, elect to implement internal policies and procedures designed to limit such consequences, which may cause the Fund to be unable to engage in certain activities, including purchasing or disposing of securities, when it might otherwise be desirable for it to do so.

Conflicts may also arise because portfolio decisions regarding the Fund may benefit other accounts managed by BlackRock or its Affiliates or a Barclays Entity. For example, the sale of a long position or establishment of a short position by the Fund

may impair the price of the same security sold short by (and therefore benefit) one or more Affiliates or Barclays Entities or their other accounts, and the purchase of a security or covering of a short position in a security by the Fund may increase the price of the same security held by (and therefore benefit) one or more Affiliates or Barclays Entities or their other accounts.

BlackRock and its Affiliates or a Barclays Entity and their clients may pursue or enforce rights with respect to an issuer in which the Fund has invested, and those activities may have an adverse effect on the Fund. As a result, prices, availability, liquidity and terms of the Fund’s investments may be negatively impacted by the activities of BlackRock or its Affiliates or a Barclays Entity or their clients, and transactions for the Fund may be impaired or effected at prices or terms that may be less favorable than would otherwise have been the case.

The results of the Fund’s investment activities may differ significantly from the results achieved by BlackRock and its Affiliates or the Barclays Entities for their proprietary accounts or other accounts (including investment companies or collective investment vehicles) managed or advised by them. It is possible that one or more Affiliate- or Barclays Entity-managed accounts and such other accounts will achieve investment results that are substantially more or less favorable than the results achieved by the Fund. Moreover, it is possible that the Fund will sustain losses during periods in which one or more Affiliates or Barclays Entity-managed accounts achieve significant profits on their trading for proprietary or other accounts. The opposite result is also possible. The investment activities of one or more Affiliates or Barclays Entities for their proprietary accounts and accounts under their management may also limit the investment opportunities for the Fund in certain emerging and other markets in which limitations are imposed upon the amount of investment, in the aggregate or in individual issuers, by affiliated foreign investors.

From time to time, the Fund’s activities may also be restricted because of regulatory restrictions applicable to one or more Affiliates or Barclays Entities, and/or their internal policies designed to comply with such restrictions. As a result, there may be periods, for example, when BlackRock, and/or one or more Affiliates or Barclays Entities, will not initiate or recommend certain types of transactions in certain securities or instruments with respect to which BlackRock and/or one or more Affiliates or Barclays Entities are performing services or when position limits have been reached.

In connection with its management of the Fund, BlackRock may have access to certain fundamental analysis and proprietary technical models developed by one or more Affiliates or Barclays Entities. BlackRock will not be under any obligation, however, to effect transactions on behalf of the Fund in accordance with such analysis and models. In addition, neither BlackRock nor any of its Affiliates, nor any Barclays Entity, will have any obligation to make available any information regarding their proprietary activities or strategies, or the activities or strategies used for other accounts managed by them, for the benefit of the management of the Fund and it is not anticipated that BlackRock will have access to such information for the purpose of managing the Fund. The proprietary activities or portfolio strategies of BlackRock and its Affiliates and the Barclays Entities, or the activities or strategies used for accounts managed by them or other customer accounts could conflict with the transactions and strategies employed by BlackRock in managing the Fund.

In addition, certain principals and certain employees of BlackRock are also principals or employees of Affiliates. As a result, the performance by these principals and employees of their obligations to such other entities may be a consideration of which investors in the Fund should be aware.

BlackRock may enter into transactions and invest in securities, instruments and currencies on behalf of the Fund in which customers of BlackRock or its Affiliates or a Barclays Entity, or, to the extent permitted by the SEC, BlackRock or another Affiliate or a Barclays Entity, serves as the counterparty, principal or issuer. In such cases, such party’s interests in the transaction will be adverse to the interests of the Fund, and such party may have no incentive to assure that the Fund obtains the best possible prices or terms in connection with the transactions. In addition, the purchase, holding and sale of such investments by the Fund may enhance the profitability of BlackRock or its Affiliates or a Barclays Entity. One or more Affiliates or Barclays Entities may also create, write or issue derivatives for their customers, the underlying securities, currencies or instruments of which may be those in which the Fund invests or which may be based on the performance of the Fund. The Fund may, subject to applicable law, purchase investments that are the subject of an underwriting or other distribution by one or more Affiliates or Barclays Entities and may also enter into transactions with other clients of an Affiliate or Barclays Entity where such other clients have interests adverse to those of the Fund.

At times, these activities may cause departments of BlackRock or its Affiliates or a Barclays Entity to give advice to clients that may cause these clients to take actions adverse to the interests of the Fund. To the extent affiliated transactions are permitted, the Fund will deal with BlackRock and its Affiliates or Barclays Entities on an arms-length basis. BlackRock or its

Affiliates or a Barclays Entity may also have an ownership interest in certain trading or information systems used by the Fund. The Fund’s use of such trading or information systems may enhance the profitability of BlackRock and its Affiliates or Barclays Entities.

One or more Affiliates or one of the Barclays Entities may act as broker, dealer, agent, lender or adviser or in other commercial capacities for the Fund. It is anticipated that the commissions, mark-ups, mark-downs, financial advisory fees, underwriting and placement fees, sales fees, financing and commitment fees, brokerage fees, other fees, compensation or profits, rates, terms and conditions charged by an Affiliate or Barclays Entity will be in its view commercially reasonable, although each Affiliate or Barclays Entity, including its sales personnel, will have an interest in obtaining fees and other amounts that are favorable to the Affiliate or Barclays Entity and such sales personnel.

Subject to applicable law, the Affiliates and Barclays Entities (and their personnel and other distributors) will be entitled to retain fees and other amounts that they receive in connection with their service to the Fund as broker, dealer, agent, lender, adviser or in other commercial capacities and no accounting to the Fund or its shareholders will be required, and no fees or other compensation payable by the Fund or its shareholders will be reduced by reason of receipt by an Affiliate or Barclays Entity of any such fees or other amounts.

When an Affiliate or Barclays Entity acts as broker, dealer, agent, adviser or in other commercial capacities in relation to the Fund, the Affiliate or Barclays Entity may take commercial steps in its own interests, which may have an adverse effect on the Fund. The Fund will be required to establish business relationships with its counterparties based on the Fund’s own credit standing. Neither BlackRock nor any of the Affiliates, nor any Barclays Entity, will have any obligation to allow their credit to be used in connection with the Fund’s establishment of its business relationships, nor is it expected that the Fund’s counterparties will rely on the credit of BlackRock or any of the Affiliates or Barclays Entities in evaluating the Fund’s creditworthiness.

Purchases and sales of securities for the Fund may be bunched or aggregated with orders for other BlackRock client accounts. BlackRock, however, is not required to bunch or aggregate orders if portfolio management decisions for different accounts are made separately, or if it determines that bunching or aggregating is not practicable or required, or in cases involving client direction.

Prevailing trading activity frequently may make impossible the receipt of the same price or execution on the entire volume of securities purchased or sold. When this occurs, the various prices may be averaged, and the Fund will be charged or credited with the average price. Thus, the effect of the aggregation may operate on some occasions to the disadvantage of the Fund. In addition, under certain circumstances, the Fund will not be charged the same commission or commission equivalent rates in connection with a bunched or aggregated order.

BlackRock may select brokers (including, without limitation, Affiliates or Barclays Entities) that furnish BlackRock, the Fund, other BlackRock client accounts or other Affiliates or Barclays Entities or personnel, directly or through correspondent relationships, with research or other appropriate services which provide, in BlackRock’s view, appropriate assistance to BlackRock in the investment decision-making process (including with respect to futures, fixed-price offerings and over-the-counter transactions). Such research or other services may include, to the extent permitted by law, research reports on companies, industries and securities; economic and financial data; financial publications; proxy analysis; trade industry seminars; computer data bases; research-oriented software and other services and products. Research or other services obtained in this manner may be used in servicing any or all of the Fund and other BlackRock client accounts, including in connection with BlackRock client accounts other than those that pay commissions to the broker relating to the research or other service arrangements. Such products and services may disproportionately benefit other BlackRock client accounts relative to the Fund based on the amount of brokerage commissions paid by the Fund and such other BlackRock client accounts. For example, research or other services that are paid for through one client’s commissions may not be used in managing that client’s account. In addition, other BlackRock client accounts may receive the benefit, including disproportionate benefits, of economies of scale or price discounts in connection with products and services that may be provided to the Fund and to such other BlackRock client accounts. To the extent that BlackRock uses soft dollars, it will not have to pay for those products and services itself.

BlackRock may receive research that is bundled with the trade execution, clearing, and/or settlement services provided by a particular broker-dealer. To the extent that BlackRock receives research on this basis, many of the same conflicts related to

traditional soft dollars may exist. For example, the research effectively will be paid by client commissions that also will be used to pay for the execution, clearing, and settlement services provided by the broker-dealer and will not be paid by BlackRock.

BlackRock may endeavor to execute trades through brokers who, pursuant to such arrangements, provide research or other services in order to ensure the continued receipt of research or other services BlackRock believes are useful in its investment decision-making process. BlackRock may from time to time choose not to engage in the above described arrangements to varying degrees. BlackRock may also enter into commission sharing arrangements under which BlackRock may execute transactions through a broker-dealer, including, where permitted, an Affiliate or Barclays Entity, and request that the broker-dealer allocate a portion of the commissions or commission credits to another firm that provides research to BlackRock. To the extent that BlackRock engages in commission sharing arrangements, many of the same conflicts related to traditional soft dollars may exist.

BlackRock may utilize certain electronic crossing networks (“ECNs”) in executing client securities transactions for certain types of securities. These ECNs may charge fees for their services, including access fees and transaction fees. The transaction fees, which are similar to commissions or markups/markdowns, will generally be charged to clients and, like commissions and markups/markdowns, would generally be included in the cost of the securities purchased. Access fees may be paid by BlackRock even though incurred in connection with executing transactions on behalf of clients, including the Fund. In certain circumstances, ECNs may offer volume discounts that will reduce the access fees typically paid by BlackRock. This would have the effect of reducing the access fees paid by BlackRock. BlackRock will only utilize ECNs consistent with its obligation to seek to obtain best execution in client transactions.

BlackRock has adopted policies and procedures designed to prevent conflicts of interest from influencing proxy voting decisions that it makes on behalf of advisory clients, including the Fund, and to help ensure that such decisions are made in accordance with BlackRock’s fiduciary obligations to its clients. Nevertheless, notwithstanding such proxy voting policies and procedures, actual proxy voting decisions of BlackRock may have the effect of favoring the interests of other clients or businesses of other divisions or units of BlackRock and/or its Affiliates or a Barclays Entity, provided that BlackRock believes such voting decisions to be in accordance with its fiduciary obligations. For a more detailed discussion of these policies and procedures, see the Proxy Voting Policy section of this SAI.

It is also possible that, from time to time, BlackRock or its Affiliates or a Barclays Entity may, although they are not required to, purchase and hold shares of the Fund. Increasing the Fund’s assets may enhance investment flexibility and diversification and may contribute to economies of scale that tend to reduce the Fund’s expense ratio. BlackRock and its Affiliates or Barclays Entities reserve the right to redeem at any time some or all of the shares of the Fund acquired for their own accounts. A large redemption of shares of the Fund by BlackRock or its Affiliates or by a Barclays Entity could significantly reduce the asset size of the Fund, which might have an adverse effect on the Fund’s investment flexibility, portfolio diversification and expense ratio. BlackRock will consider the effect of redemptions on the Fund and other shareholders in deciding whether to redeem its shares.

It is possible that the Fund may invest in securities of companies with which an Affiliate or a Barclays Entity has or is trying to develop investment banking relationships as well as securities of entities in which BlackRock or its Affiliates or a Barclays Entity has significant debt or equity investments or in which an Affiliate or Barclays Entity makes a market. The Fund also may invest in securities of companies to which an Affiliate or a Barclays Entity provides or may some day provide research coverage. Such investments could cause conflicts between the interests of the Fund and the interests of other clients of BlackRock or its Affiliates or a Barclays Entity. In making investment decisions for the Fund, BlackRock is not permitted to obtain or use material non-public information acquired by any division, department or Affiliate of BlackRock or of a Barclays Entity in the course of these activities. In addition, from time to time, the activities of an Affiliate or a Barclays Entity may limit the Fund’s flexibility in purchases and sales of securities. When an Affiliate is engaged in an underwriting or other distribution of securities of an entity, BlackRock may be prohibited from purchasing or recommending the purchase of certain securities of that entity for the Fund.

BlackRock and its Affiliates and the Barclays Entities, their personnel and other financial service providers may have interests in promoting sales of the Fund. With respect to BlackRock and its Affiliates and Barclays Entities and their personnel, the remuneration and profitability relating to services to and sales of the Fund or other products may be greater than remuneration and profitability relating to services to and sales of certain funds or other products that might be provided or offered. BlackRock and its Affiliates or Barclays Entities and their sales personnel may directly or indirectly receive a portion of

the fees and commissions charged to the Fund or its shareholders. BlackRock and its advisory or other personnel may also benefit from increased amounts of assets under management. Fees and commissions may also be higher than for other products or services, and the remuneration and profitability to BlackRock or its Affiliates or a Barclays Entity and such personnel resulting from transactions on behalf of or management of the Fund may be greater than the remuneration and profitability resulting from other funds or products.

BlackRock and its Affiliates or a Barclays Entity and their personnel may receive greater compensation or greater profit in connection with an account for which BlackRock serves as an adviser than with an account advised by an unaffiliated investment adviser. Differentials in compensation may be related to the fact that BlackRock may pay a portion of its advisory fee to its Affiliate or to a Barclays Entity, or relate to compensation arrangements, including for portfolio management, brokerage transactions or account servicing. Any differential in compensation may create a financial incentive on the part of BlackRock or its Affiliates or Barclays Entities and their personnel to recommend BlackRock over unaffiliated investment advisers or to effect transactions differently in one account over another.

BlackRock and its Affiliates or a Barclays Entity may provide valuation assistance to certain clients with respect to certain securities or other investments and the valuation recommendations made for their clients’ accounts may differ from the valuations for the same securities or investments assigned by the Fund’s pricing vendors, especially if such valuations are based on broker-dealer quotes or other data sources unavailable to the Fund’s pricing vendors. While BlackRock will generally communicate its valuation information or determinations to the Fund’s pricing vendors and/or fund accountants, there may be instances where the Fund’s pricing vendors or fund accountants assign a different valuation to a security or other investment than the valuation for such security or investment determined or recommended by BlackRock.

As disclosed in more detail in the Determination of Net Asset Value section of the Fund’s Prospectus, when market valuations are not readily available or such valuations do not reflect current market values, the affected investments will be valued using fair value pricing, pursuant to procedures adopted by the Fund’s Board. As a result, the Fund’s sale or redemption of its shares at net asset value, at a time when a holding or holdings are valued by BlackRock (pursuant to Board-adopted procedures) at fair value, may have the effect of diluting or increasing the economic interest of existing shareholders.

To the extent permitted by applicable law, the Fund may invest all or some of its short term cash investments in any money market fund or similarly-managed private fund advised or managed by BlackRock. In connection with any such investments, the Fund, to the extent permitted by the 1940 Act, may pay its share of expenses of a money market fund in which it invests, which may result in the Fund bearing some additional expenses.

BlackRock and its Affiliates or a Barclays Entity and their directors, officers and employees, may buy and sell securities or other investments for their own accounts, and may have conflicts of interest with respect to investments made on behalf of the Fund. As a result of differing trading and investment strategies or constraints, positions may be taken by directors, officers, employees and Affiliates of BlackRock or by Barclays Entities that are the same, different from or made at different times than positions taken for the Fund. To lessen the possibility that the Fund will be adversely affected by this personal trading, the Fund, BFA and BlackRock each has adopted a Code of Ethics in compliance with Section 17(j) of the 1940 Act that restricts securities trading in the personal accounts of investment professionals and others who normally come into possession of information regarding the Fund’s portfolio transactions. Each Code of Ethics can be reviewed and copied at the SEC’s Public Reference Room in Washington, D.C. Information on the operation of the Public Reference Room may be obtained by calling the SEC at (202) 551-8090. Each Code of Ethics is also available on the EDGAR Database on the SEC’s Internet site at http://www.sec.gov, and copies may be obtained, after paying a duplicating fee, by e-mail at publicinfo@sec.gov or by writing the SEC’s Public Reference Section, Washington, DC 20549-1520.

BlackRock and its Affiliates will not purchase securities or other property from, or sell securities or other property to, the Fund, except that the Fund may in accordance with rules adopted under the 1940 Act engage in transactions with accounts that are affiliated with the Fund as a result of common officers, directors, or investment advisers or pursuant to exemptive orders granted to the Fund and/or BlackRock by the SEC. These transactions would be affected in circumstances in which BlackRock determined that it would be appropriate for the Fund to purchase and another client of BlackRock to sell, or the Fund to sell and another client of BlackRock to purchase, the same security or instrument on the same day. From time to time, the activities of the Fund may be restricted because of regulatory requirements applicable to BlackRock or its Affiliates or a Barclays Entity and/or BlackRock’s internal policies designed to comply with, limit the applicability of, or otherwise relate to such requirements. A client not advised by BlackRock would not be subject to some of those considerations. There may be periods when BlackRock may not initiate or recommend certain types of transactions, or may otherwise restrict or limit their

advice in certain securities or instruments issued by or related to companies for which an Affiliate or a Barclays Entity is performing investment banking, market making or other services or has proprietary positions. For example, when an Affiliate is engaged in an underwriting or other distribution of securities of, or advisory services for, a company, the Fund may be prohibited from or limited in purchasing or selling securities of that company. Similar situations could arise if personnel of BlackRock or its Affiliates or a Barclays Entity serve as directors of companies the securities of which the Fund wishes to purchase or sell. However, if permitted by applicable law, the Fund may purchase securities or instruments that are issued by such companies or are the subject of an underwriting, distribution, or advisory assignment by an Affiliate or a Barclays Entity, or in cases in which personnel of BlackRock or its Affiliates or of Barclays Entities are directors or officers of the issuer.

The investment activities of one or more Affiliates or Barclays Entities for their proprietary accounts and for client accounts may also limit the investment strategies and rights of the Fund. For example, in regulated industries, in certain emerging or international markets, in corporate and regulatory ownership definitions, and in certain futures and derivative transactions, there may be limits on the aggregate amount of investment by affiliated investors that may not be exceeded without the grant of a license or other regulatory or corporate consent or, if exceeded, may cause BlackRock, the Fund or other client accounts to suffer disadvantages or business restrictions.

If certain aggregate ownership thresholds are reached or certain transactions undertaken, the ability of BlackRock on behalf of clients (including the Fund) to purchase or dispose of investments, or exercise rights or undertake business transactions, may be restricted by regulation or otherwise impaired. As a result, BlackRock, on behalf of clients (including the Fund), may limit purchases, sell existing investments, or otherwise restrict or limit the exercise of rights (including voting rights) when BlackRock, in its sole discretion, deems it appropriate.

BlackRock and its Affiliates and Barclays Entities may maintain securities indices as part of their product offerings. Index based funds seek to track the performance of securities indices and may use the name of the index in the fund name. Index providers, including BlackRock and its Affiliates and Barclays Entities may be paid licensing fees for use of their index or index name. BlackRock and its Affiliates and Barclays Entities will not be obligated to license their indices to BlackRock, and BlackRock cannot be assured that the terms of any index licensing agreement with BlackRock and its Affiliates and Barclays Entities will be as favorable as those terms offered to other index licensees.

BlackRock and its Affiliates and Barclays Entities may serve as Authorized Participants in the creation and redemption of exchange-traded funds, including funds advised by Affiliates of BlackRock. As described in greater detail in the Creations and Redemptions section of the prospectus, BlackRock and its Affiliates and Barclays Entities may therefore be deemed to be participants in a distribution of iShares funds that could render them statutory underwriters.

Present and future activities of BlackRock and its Affiliates and Barclays Entities, including BlackRock Advisors, LLC, in addition to those described in this section, may give rise to additional conflicts of interest.

Investment Advisory, Administrative and Distribution Services

Investment Adviser. BFA serves as investment adviser to the Fund pursuant to an Investment Advisory Agreement between the Trust, on behalf of the Fund, and BFA. BFA is a California corporation indirectly owned by BlackRock, Inc. and is registered as an investment adviser under the Investment Advisers Act of 1940, as amended. Under the Investment Advisory Agreement, BFA, subject to the supervision of the Board and in conformity with the stated investment policies of the Fund, manages and administers the Trust and the investment of the Fund’s assets. BFA is responsible for placing purchase and sale orders and providing continuous supervision of the investment portfolio of the Fund.

Pursuant to the Investment Advisory Agreement, BFA may, from time to time, in its sole discretion and to the extent permitted by applicable law, appoint one or more sub-advisers, including, without limitation, affiliates of BFA, to perform investment advisory or other services with respect to the Fund. In addition, BFA may delegate certain of its investment advisory functions under the Investment Advisory Agreement to one or more of its affiliates to the extent permitted by applicable law. BFA may terminate any or all sub-advisers or such delegation arrangements in its sole discretion upon appropriate notice at any time to the extent permitted by applicable law.

Pursuant to the Investment Advisory Agreement, BFA is responsible for substantially all expenses of the Fund, including the cost of transfer agency, custody, fund administration, legal, audit and other services. BFA is not responsible for, and the Fund will bear the cost of, interest expense, taxes, brokerage expenses and other expenses connected with the execution of portfolio securities transactions, distribution fees and extraordinary expenses.

For its investment advisory services to the Fund, BFA received a management fee from the Fund, based on a percentage of the Fund’s average daily net assets, at an annual rate of 0.25%.

The Investment Advisory Agreement with respect to the Fund continues in effect for two years from its effective date, and thereafter is subject to annual approval by (i) the Board, or (ii) the vote of a majority of the outstanding voting securities (as defined in the 1940 Act) of the Fund, provided that in either event such continuance also is approved by a majority of the Board who are not interested persons (as defined in the 1940 Act) of the Fund, by a vote cast in person at a meeting called for the purpose of voting on such approval.

The Investment Advisory Agreement with respect to the Fund is terminable without penalty, on 60 days’ notice, by the Board or by a vote of the holders of a majority of the Fund’s outstanding voting securities (as defined in the 1940 Act). The Investment Advisory Agreement is also terminable upon 60 days’ notice by BFA and will terminate automatically in the event of its assignment (as defined in the 1940 Act).

Current interpretations of U.S. federal banking laws and regulations (i) may prohibit BlackRock, Inc., BTC and BFA from controlling or underwriting the shares of the Fund, but (ii) do not prohibit BlackRock, Inc. or BFA generally from acting as an investment adviser, administrator, transfer agent or custodian to the Fund or from purchasing shares as agent for and upon the order of a customer.

BFA believes that it may perform advisory and related services for the Trust without violating applicable banking laws or regulations. However, the legal requirements and interpretations about the permissible activities of banks and their affiliates may change in the future. These changes could prevent BFA from continuing to perform services for the Trust. If this happens, the Board would consider selecting other qualified firms. Any new investment advisory agreement would be subject to shareholder approval.

If current restrictions on bank activities with mutual funds were relaxed, BFA, or its affiliates, would consider performing additional services for the Trust. BFA cannot predict whether these changes will be enacted, or the terms under which BFA, or its affiliates, might offer to provide additional services.

Portfolio Managers. As of July 31, 2011, the individuals named as Portfolio Managers in the Fund’s Prospectus were also primarily responsible for the day-to-day management of other iShares funds and certain other types of portfolios and/or accounts as indicated in the tables below:

Accounts with Incentive-Based Fee Arrangements 0 N/A

Each of the portfolios or accounts for which the Portfolio Managers are primarily responsible for the day-to-day management seeks to track the rate of return, risk profile and other characteristics of independent third-party indexes by either replicating the same combination of securities that constitute those indexes or through a representative sampling of the securities that constitute those indexes based on objective criteria and data. Pursuant to BTC and BFA policy, investment opportunities are allocated equitably among the Fund and other portfolios and accounts. For example, under certain circumstances, an investment opportunity may be restricted due to limited supply on the market, legal constraints or other factors, in which event the investment opportunity will be allocated equitably among those portfolios and accounts, including the Fund seeking such investment opportunity. As a consequence, from time to time the Fund may receive a smaller allocation of an investment opportunity than it would have if the Portfolio Managers and BFA and its affiliates did not manage other portfolios or accounts.

Like the Fund, the other portfolios or accounts for which the Portfolio Managers are primarily responsible for the day-to-day portfolio management generally pay an asset-based fee to BFA or BTC, as applicable, for its advisory services. One or more of those other portfolios or accounts, however, may pay BTC an incentive-based fee in lieu of, or in addition to, an asset-based fee for its advisory services. A portfolio or account with an incentive-based fee would pay BTC a portion of that portfolio’s or account’s gains, or would pay BTC more for its services than would otherwise be the case if BTC meets or exceeds specified performance targets. By their nature, incentive-based fee arrangements could present an incentive for BTC to devote greater resources, and allocate more investment opportunities, to the portfolios or accounts that have those fee arrangements, relative to other portfolios or accounts, in order to earn larger fees. Although BTC has an obligation to allocate resources and opportunities equitably among portfolios and accounts and intends to do so, shareholders of the Fund should be aware that, as with any group of portfolios and accounts managed by an investment adviser and/or its affiliates pursuant to varying fee arrangements, including incentive-based fee arrangements, there is the potential for a conflict of interest that may result in the Portfolio Managers’ favoring those portfolios or accounts with incentive-based fee arrangements.

The tables below show, for each Portfolio Manager, the number of portfolios or accounts of the types set forth in the above tables and the aggregate of total assets in those portfolios or accounts with respect to which the investment management fees are based on the performance of those portfolios or accounts as of July 31, 2011:

The discussion below describes the Portfolio Managers’ compensation as of July 31, 2011.

Portfolio Manager Compensation Overview

Base compensation. Generally, portfolio managers receive base compensation based on their seniority and/or their position with the firm. Senior portfolio managers who perform additional management functions within the portfolio management group or within BlackRock may receive additional compensation for serving in these other capacities.

Discretionary Incentive Compensation. Discretionary incentive compensation is a function of several components: the performance of BlackRock, Inc., the performance of the portfolio manager’s group within BlackRock, the investment performance, including risk-adjusted returns, of the firm’s assets under management or supervision by that portfolio manager relative to predetermined benchmarks, and the individual’s seniority, role within the portfolio management team, teamwork and contribution to the overall performance of these portfolios and BlackRock.

Distribution of Discretionary Incentive Compensation. Discretionary incentive compensation is distributed to portfolio managers in a combination of cash and BlackRock, Inc. restricted stock units which vest ratably over a number of years. The BlackRock, Inc. restricted stock units, if properly vested, will be settled in BlackRock, Inc. common stock. Typically, the cash bonus, when combined with base salary, represents more than 60% of total compensation for the portfolio managers. Paying a portion of annual bonuses in stock puts compensation earned by a portfolio manager for a given year “at risk” based on BlackRock’s ability to sustain and improve its performance over future periods.

From time to time, long-term incentive equity awards are granted to certain key employees to aid in retention, align their interests with long-term shareholder interests and motivate performance. Equity awards are generally granted in the form of BlackRock, Inc. restricted stock units that, once vested, settle in BlackRock, Inc. common stock.

As of July 31, 2011, the Portfolio Managers did not beneficially own shares of the Fund.

Codes of Ethics. The Trust, BFA and the Distributor have adopted Codes of Ethics pursuant to Rule 17j-1 of the 1940 Act. The Codes of Ethics permit personnel subject to the Codes of Ethics to invest in securities, subject to certain limitations, including securities that may be purchased or held by the Fund. The Codes of Ethics are on public file with, and are available from, the SEC.

Anti-Money Laundering Requirements. The Fund is subject to the USA PATRIOT Act (the “Patriot Act”). The Patriot Act is intended to prevent the use of the U.S. financial system in furtherance of money laundering, terrorism or other illicit activities. Pursuant to requirements under the Patriot Act, the Fund may request information from Authorized Participants to enable it

to form a reasonable belief that it knows the true identity of its Authorized Participants. This information will be used to verify the identity of Authorized Participants or, in some cases, the status of financial professionals; it will be used only for compliance with the requirements of the Patriot Act.

The Fund reserves the right to reject purchase orders from persons who have not submitted information sufficient to allow the Fund to verify their identity. The Fund also reserves the right to redeem any amounts in the Fund from persons whose identity it is unable to verify on a timely basis. It is the Fund’s policy to cooperate fully with appropriate regulators in any investigations conducted with respect to potential money laundering, terrorism or other illicit activities.

Administrator, Custodian and Transfer Agent. State Street Bank and Trust Company (“State Street”) serves as administrator, custodian and transfer agent for the Fund under the Master Services Agreement and related Service Schedule (the “Service Module”). State Street’s principal address is 200 Clarendon Street, Boston, MA 02116. Pursuant to the Service Module for Fund Administration and Accounting Services with the Trust, State Street provides necessary administrative, legal, tax and accounting and financial reporting services for the maintenance and operations of the Trust and the Fund. In addition, State Street makes available the office space, equipment, personnel and facilities required to provide such services. Pursuant to the Service Module for Custodial Services with the Trust, State Street maintains, in separate accounts, cash, securities and other assets of the Trust and the Fund, keeps all necessary accounts and records and provides other services. State Street is required, upon the order of the Trust, to deliver securities held by State Street and to make payments for securities purchased by the Trust for the Fund. State Street is authorized to appoint certain foreign custodians or foreign custody managers for Fund investments outside the United States. Pursuant to the Service Module for Transfer Agency Services with the Trust, State Street acts as a transfer agent for the Fund’s authorized and issued shares of beneficial interest, and as dividend disbursing agent of the Trust. As compensation for these services, State Street receives certain out-of-pocket costs, transaction fees and asset-based fees which are accrued daily and paid monthly by BFA from its management fee.

The following table sets forth the administration, transfer agency and custodian expenses of the Fund paid by BFA to State Street for the fiscal years noted:

Distributor. The Distributor’s principal address is One Freedom Valley Drive, Oaks, PA 19456. The Distributor has entered into a Distribution Agreement with the Trust pursuant to which it distributes shares of the Fund. The Distribution Agreement will continue for two years from its effective date and is renewable annually. Shares are continuously offered for sale by the Fund through the Distributor only in Creation Units, as described in the Prospectus and below in the Creation and Redemption of Creation Units section of this SAI. Fund shares in amounts less than Creation Units are not distributed by the Distributor. The Distributor will deliver the Prospectus and, upon request, the SAI to persons purchasing Creation Units and will maintain records of both orders placed with it and confirmations of acceptance furnished by it. The Distributor is a broker-dealer registered under the Securities Exchange Act of 1934, as amended (the “1934 Act”), and a member of the Financial Industry Regulatory Authority, Inc. (“FINRA”).

The Distribution Agreement for the Fund provides that it may be terminated at any time, without the payment of any penalty, on at least 60 days’ prior written notice to the other party following (i) the vote of a majority of the Independent Trustees, or (ii) the vote of a majority of the outstanding voting securities (as defined in the 1940 Act) of the Fund. The Distribution Agreement will terminate automatically in the event of its assignment (as defined in the 1940 Act).

The Distributor may also enter into agreements with securities dealers (“Soliciting Dealers”) who will solicit purchases of Creation Units of Fund shares. Such Soliciting Dealers may also be Authorized Participants (as defined below), DTC participants and/or investor services organizations.

BFA or BTC may, from time to time and from its own resources, pay, defray or absorb costs relating to distribution, including payments out of its own resources to the Distributor, or to otherwise promote the sale of shares.

The following table sets forth the compensation paid by BFA to the Distributor for certain services, not primarily intended to result in the sale of Fund shares, provided to the Fund for the fiscal years noted:

Financial Intermediary Compensation. BFA and/or BTC and/or their respective subsidiaries (“BFA Entities”) pay certain broker-dealers, banks and other financial intermediaries (“Intermediaries”) for certain activities related to the Fund, other iShares funds or exchange-traded products in general (“Payments”). BFA Entities make Payments from their own assets and not from the assets of the Fund. Although a portion of BFA Entities’ revenue comes directly or indirectly in part from fees paid by the Fund and other iShares funds, Payments do not increase the price paid by investors for the purchase of shares of, or the cost of owning, the Fund or other iShares funds. BFA Entities make Payments for Intermediaries’ participating in activities that are designed to make registered representatives, other professionals and individual investors more knowledgeable about exchange-traded products, including the Fund or for other activities, such as participation in marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems (“Education Costs”). BFA Entities also make Payments to Intermediaries for certain printing, publishing and mailing costs associated with the Fund or materials relating to exchange-traded products in general (“Publishing Costs”). In addition, BFA Entities make Payments to Intermediaries that make shares of the Fund and certain other iShares funds available to their clients, develop new products that feature iShares or otherwise promote the Fund and other iShares funds. Payments of this type are sometimes referred to as revenue-sharing payments.

Payments to an Intermediary may be significant to the Intermediary, and amounts that Intermediaries pay to your salesperson or other investment professional may also be significant for your salesperson or other investment professional. Because an Intermediary may make decisions about which investment options it will recommend or make available to its clients or what services to provide for various products based on payments it receives or is eligible to receive, Payments create conflicts of interest between the Intermediary and its clients and these financial incentives may cause the Intermediary to recommend the Fund and other iShares funds over other investments. The same conflict of interest exists with respect to your salesperson or other investment professional if he or she receives similar payments from his or her Intermediary firm.

As of February 2, 2010, BFA Entities had arrangements to make Payments other than Education Costs or Publishing Costs only to Fidelity Brokerage Services LLC (“FBS”) and Merrill Lynch, Pierce, Fenner & Smith, Inc. (“ML”). Pursuant to BFA Entities’ arrangement with FBS, FBS has agreed to promote iShares funds to FBS’s customers and not to charge certain of its customers any commissions when those customers purchase or sell shares of certain iShares funds online (the “Co-Branded Marketing Program”). BFA Entities have agreed to facilitate the Co-Branded Marketing Program by making payments to FBS during the term of the agreement in a fixed amount. Upon termination of the agreement the BFA Entities will make additional payments to FBS based upon a number of criteria, including the overall success of the Co-Branded Marketing program and the level of services provided by FBS during the wind-down period. Pursuant to BFA Entities’ arrangement with ML, BFA Entities have agreed to reimburse ML for a portion of certain fee waivers that ML may be required to implement with respect to accounts that hold “plan assets” within the meaning of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”), as a consequence of a technical ERISA affiliate relationship between BFA and ML.

Any additions, modifications, or deletions to Intermediaries listed above that have occurred since the date noted above are not included in the list. Further, BFA Entities make Education Costs and Publishing Costs Payments to other Intermediaries that are not listed above. BFA Entities may determine to make Payments based on any number of metrics. For example, BFA Entities may make Payments at year-end or other intervals in a fixed amount, an amount based upon an Intermediary’s services at defined levels or an amount based on the Intermediary’s net sales of one or more iShares funds in a year or other period, any of which arrangements may include an agreed-upon minimum or maximum payment, or any combination of the foregoing. As of the date of this SAI, BFA anticipates that the Payments paid by BFA Entities in connection with the Fund, iShares funds and exchange-traded products in general will be immaterial to BFA Entities in the aggregate for the next year. Please contact your salesperson or other investment professional for more information regarding any Payments his or her Intermediary firm may receive. Any Payments made by the BFA Entities to an Intermediary may create the incentive for an Intermediary to encourage customers to buy shares of iShares funds.

Brokerage Transactions

BFA assumes general supervision over placing orders on behalf of the Fund for the purchase and sale of portfolio securities. In selecting brokers or dealers for any transaction in portfolio securities, BFA’s policy is to make such selection based on factors deemed relevant, including but not limited to, the breadth of the market in the security, the price of the security, the reasonableness of the commission or mark-up or mark-down, if any, execution capability, settlement capability, back office efficiency and the financial condition of the broker or dealer, both for the specific transaction and on a continuing basis. The overall reasonableness of brokerage commissions paid is evaluated by BFA based upon its knowledge of available information as to the general level of commissions paid by other institutional investors for comparable services. Brokers may also be selected because of their ability to handle special or difficult executions, such as may be involved in large block trades, less liquid securities, broad distributions, or other circumstances. BFA does not consider the provision or value of research, products or services a broker or dealer may provide, if any, as a factor in the selection of a broker or dealer or the determination of the reasonableness of commissions paid in connection with portfolio transactions. The Trust has adopted policies and procedures that prohibit the consideration of sales of the Fund’s shares as a factor in the selection of a broker or a dealer to execute its portfolio transactions.

The table below sets forth the brokerage commissions paid by the Fund for the fiscal years noted. Any differences in brokerage commissions paid by the Fund from year to year are due to increases or decreases in the Fund’s assets over those periods:

The following table sets forth the names of the Fund’s “regular broker dealers,” as defined under Rule 10b-1 of the 1940 Act, which derive more than 15% of their gross revenues from securities-related activities and in which the Fund invests, together with the market value of each investment as of the Fund’s fiscal year ended July 31, 2011:

Morgan Stanley 760,950

The Fund did not pay any brokerage commissions to BlackRock, an affiliate of BFA, and a subsidiary of BTC, during the fiscal year ended July 31, 2011.

The Fund’s purchase and sale orders for securities may be combined with those of other investment companies, clients or accounts that BFA or its Affiliates manage or advise and for which they have brokerage placement authority. If purchases or sales of portfolio securities of the Fund and one or more other accounts managed or advised by BFA or its Affiliates are considered at or about the same time, transactions in such securities are allocated among the Fund and the other accounts in a manner deemed equitable to all by BFA and its Affiliates. In some cases, this procedure could have a detrimental effect on the price or volume of the security as far as the Fund is concerned. However, in other cases, it is possible that the ability to participate in volume transactions and to negotiate lower transaction costs will be beneficial to the Fund. BFA and its Affiliates may deal, trade and invest for their own account in the types of securities in which the Fund may invest. BFA and its Affiliates may, from time to time, effect trades on behalf of and for the account of the Fund with brokers or dealers that are affiliated with BFA, in conformity with the 1940 Act and SEC rules and regulations. Under these provisions, any commissions

paid to affiliated brokers or dealers must be reasonable and fair compared to the commissions charged by other brokers or dealers in comparable transactions. The Fund will not deal with affiliates in principal transactions unless permitted by applicable SEC rules or regulations, or by SEC exemptive order.

Portfolio turnover may vary from year to year, as well as within a year. High turnover rates may result in comparatively greater brokerage expenses. The table below sets forth the portfolio turnover rates of the Fund for the fiscal years noted:

Additional Information Concerning the Trust

Shares. The Trust currently consists of more than 190 separate investment series or portfolios called funds. The Trust issues shares of beneficial interests in each fund with no par value. The Board may designate additional iShares funds.

Each share issued by a fund has a pro rata interest in the assets of that fund. Shares have no preemptive, exchange, subscription or conversion rights and are freely transferable. Each share is entitled to participate equally in dividends and distributions declared by the Board with respect to the relevant fund, and in the net distributable assets of such fund on liquidation.

Each share has one vote with respect to matters upon which the shareholder is entitled to vote. In any matter submitted to shareholders for a vote, each fund shall hold a separate vote, provided that shareholders of all affected funds will vote together when: (1) required by the 1940 Act, or (2) the Trustees determine that the matter affects the interests of more than one fund.

Under Delaware law, the Trust is not required to hold an annual meeting of shareholders unless required to do so under the 1940 Act. The policy of the Trust is not to hold an annual meeting of shareholders unless required to do so under the 1940 Act. All shares (regardless of the fund) have noncumulative voting rights in the election of members of the Board. Under Delaware law, Trustees of the Trust may be removed by vote of the shareholders.

Following the creation of the initial Creation Unit(s) of shares of a fund and immediately prior to the commencement of trading in the fund’s shares, a holder of shares may be a “control person” of the fund, as defined in the 1940 Act. The fund cannot predict the length of time for which one or more shareholders may remain a control person of the fund.

In accordance with the Trust’s Amended and Restated Agreement and Declaration of Trust dated September 17, 2009 (the “Declaration of Trust”), the Board may, without shareholder approval (unless such shareholder approval is required by applicable law, including the 1940 Act), cause one or more funds commencing operations after September 24, 2008 (each, a “New Fund”) to merge, reorganize, consolidate, sell all or substantially all of their assets, or take other similar actions with, to or into another New Fund.

Shareholders may make inquiries by writing to iShares Trust, c/o SEI Investments Distribution Co., One Freedom Valley Drive, Oaks, PA 19456.

Absent an applicable exemption or other relief from the SEC or its staff, beneficial owners of more than 5% of the shares of a fund may be subject to the reporting provisions of Section 13 of the 1934 Act and the SEC’s rules promulgated thereunder. In addition, absent an applicable exemption or other relief from the SEC or its staff, officers and trustees of the fund and beneficial owners of 10% of the shares of the fund (“Insiders”) may be subject to the insider reporting, short-swing profit and short sale provisions of Section 16 of the 1934 Act and the SEC’s rules promulgated thereunder. Beneficial owners and Insiders should consult with their own legal counsel concerning their obligations under Sections 13 and 16 of the 1934 Act.

Termination of the Trust or the Fund. The Trust or the Fund may be terminated by a majority vote of the Board, subject to the affirmative vote of a majority of the shareholders of the Trust or the Fund entitled to vote on termination; however, in certain circumstances described in the Declaration of Trust, only a majority vote of the Board is required. Although the shares are not automatically redeemable upon the occurrence of any specific event, the Declaration of Trust provides that the Board will have the unrestricted power to alter the number of shares in a Creation Unit. In the event of a termination of the Trust or

the Fund, the Board, in its sole discretion, could determine to permit the shares to be redeemable in aggregations smaller than Creation Units or to be individually redeemable. In such circumstance, the Trust may make redemptions in-kind, for cash or for a combination of cash or securities.

DTC as Securities Depository for Shares of the Fund. Shares of the Fund are represented by securities registered in the name of DTC or its nominee and deposited with, or on behalf of, DTC.

DTC, a limited-purpose trust company, was created to hold securities of its participants (“DTC Participants”) and to facilitate the clearance and settlement of securities transactions among the DTC Participants in such securities through electronic book-entry changes in accounts of the DTC Participants, thereby eliminating the need for physical movement of securities’ certificates. DTC Participants include securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations, some of whom (and/or their representatives) own DTC. More specifically, DTC is owned by a number of its DTC Participants and by the New York Stock Exchange (“NYSE”), the NYSE Amex Equities and FINRA. Access to the DTC system is also available to others such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a DTC Participant, either directly or indirectly (“Indirect Participants”).

Beneficial ownership of shares is limited to DTC Participants, Indirect Participants and persons holding interests through DTC Participants and Indirect Participants. Ownership of beneficial interests in shares (owners of such beneficial interests are referred to herein as “Beneficial Owners”) is shown on, and the transfer of ownership is effected only through, records maintained by DTC (with respect to DTC Participants) and on the records of DTC Participants (with respect to Indirect Participants and Beneficial Owners that are not DTC Participants). Beneficial Owners will receive from or through the DTC Participant a written confirmation relating to their purchase of shares.

Conveyance of all notices, statements and other communications to Beneficial Owners is effected as follows. Pursuant to the Depositary Agreement between the Trust and DTC, DTC is required to make available to the Trust upon request and for a fee to be charged to the Trust a listing of the shares of the Fund held by each DTC Participant. The Trust shall inquire of each such DTC Participant as to the number of Beneficial Owners holding shares, directly or indirectly, through such DTC Participant. The Trust shall provide each such DTC Participant with copies of such notice, statement or other communication, in such form, number and at such place as such DTC Participant may reasonably request, in order that such notice, statement or communication may be transmitted by such DTC Participant, directly or indirectly, to such Beneficial Owners. In addition, the Trust shall pay to each such DTC Participant a fair and reasonable amount as reimbursement for the expenses attendant to such transmittal, all subject to applicable statutory and regulatory requirements.

Share distributions shall be made to DTC or its nominee, Cede & Co., as the registered holder of all shares of the Trust. DTC or its nominee, upon receipt of any such distributions, shall credit immediately DTC Participants’ accounts with payments in amounts proportionate to their respective beneficial interests in shares of the Fund as shown on the records of DTC or its nominee. Payments by DTC Participants to Indirect Participants and Beneficial Owners of shares held through such DTC Participants will be governed by standing instructions and customary practices, as is now the case with securities held for the accounts of customers in bearer form or registered in a “street name,” and will be the responsibility of such DTC Participants.

The Trust has no responsibility or liability for any aspect of the records relating to or notices to Beneficial Owners, or payments made on account of beneficial ownership interests in such shares, or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests, or for any other aspect of the relationship between DTC and the DTC Participants or the relationship between such DTC Participants and the Indirect Participants and Beneficial Owners owning through such DTC Participants. DTC may decide to discontinue providing its service with respect to shares of the Trust at any time by giving reasonable notice to the Trust and discharging its responsibilities with respect thereto under applicable law. Under such circumstances, the Trust shall take action to find a replacement for DTC to perform its functions at a comparable cost.

Creation and Redemption of Creation Units

General. The Trust issues and sells shares of the Fund only in Creation Units on a continuous basis through the Distributor, without a sales load, at a price based on the Fund’s NAV next determined after receipt, on any Business Day (as defined below), of an order in proper form. The following table sets forth the number of shares of the Fund that constitute a Creation Unit for the Fund and the value of such Creation Unit as of September 30, 2011:

Shares Per
Creation Unit
Value Per
Creation
Unit (U.S.$)
200,000 $6,922,000

The Board reserves the right to declare a split or a consolidation in the number of shares outstanding of the Fund, and to make a corresponding change in the number of shares constituting a Creation Unit, in the event that the per share price in the secondary market rises (or declines) to an amount that falls outside the range deemed desirable by the Board.

A “Business Day” with respect to the Fund is any day on which the Listing Exchange on which the Fund is listed for trading is open for business. As of the date of this SAI, the Listing Exchange observes the following holidays, as observed: New Year’s Day, Martin Luther King, Jr. Day, Presidents’ Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day.

Fund Deposit. The consideration for purchase of Creation Units of the Fund generally consists of the in-kind deposit of a designated portfolio of securities (including any portion of such securities for which cash may be substituted) (i.e., the Deposit Securities) and the Cash Component computed as described below. Together, the Deposit Securities and the Cash Component constitute the “Fund Deposit,” which when combined with the Fund’s portfolio securities is designed to generate performance that has a collective investment portfolio similar to that of the Underlying Index. The Fund Deposit represents the minimum initial and subsequent investment amount for a Creation Unit of the Fund.

The Cash Component is an amount equal to the difference between the net asset value of the shares (per Creation Unit) and the “Deposit Amount,” which is an amount equal to the market value of the Deposit Securities, and serves to compensate for any differences between the net asset value per Creation Unit and the Deposit Amount. Payment of any stamp duty or other similar fees and expenses payable upon transfer of beneficial ownership of the Deposit Securities are the sole responsibility of the Authorized Participant purchasing the Creation Unit.

BFA makes available through the NSCC on each Business Day, prior to the opening of business on the Listing Exchange, the list of names and the required number of shares of each Deposit Security and the amount of the Cash Component to be included in the current Fund Deposit (based on information as of the end of the previous Business Day) for the Fund. Such Fund Deposit is applicable, subject to any adjustments as described below, in order to effect purchases of Creation Units of shares of the Fund until such time as the next-announced Fund Deposit is made available.

The identity and number of shares of the Deposit Securities change pursuant to changes in the composition of the Fund’s portfolio and as rebalancing adjustments and corporate action events are reflected from time to time by BFA with a view to the investment objective of the Fund. The composition of the Deposit Securities may also change in response to adjustments to the weighting or composition of the component securities constituting the Underlying Index.

The Fund reserves the right to permit or require the substitution of a “cash in lieu” amount to be added to the Cash Component to replace any Deposit Security that may not be available in sufficient quantity for delivery or that may not be eligible for transfer through DTC. The Fund also reserves the right to permit or require a “cash in lieu” amount in certain circumstances, including circumstances in which (i) the delivery of the Deposit Security by the Authorized Participant (as described below) would be restricted under applicable securities laws or (ii) the delivery of the Deposit Security to the Authorized Participant would result in the disposition of the Deposit Security by the Authorized Participant becoming restricted under applicable securities laws, or in certain other situations.

Role of the Authorized Participant. Creation Units may be purchased only by or through a DTC Participant that has entered into an Authorized Participant Agreement with the Distributor (an “Authorized Participant”). Such Authorized Participant will agree, pursuant to the terms of such Authorized Participant Agreement and on behalf of itself or any investor on whose behalf it will act, to certain conditions, including that such Authorized Participant will make available in advance of each

purchase of shares an amount of cash sufficient to pay the Cash Component, once the net asset value of a Creation Unit is next determined after receipt of the purchase order in proper form, together with the transaction fee described below. The Authorized Participant may require the investor to enter into an agreement with such Authorized Participant with respect to certain matters, including payment of the Cash Component. Investors who are not Authorized Participants must make appropriate arrangements with an Authorized Participant. Investors should be aware that their particular broker may not be a DTC Participant or may not have executed an Authorized Participant Agreement and that orders to purchase Creation Units may have to be placed by the investor’s broker through an Authorized Participant. As a result, purchase orders placed through an Authorized Participant may result in additional charges to such investor. The Trust does not expect to enter into an Authorized Participant Agreement with more than a small number of DTC Participants. A list of current Authorized Participants may be obtained from the Distributor.

Purchase Orders. To initiate an order for a Creation Unit, an Authorized Participant must submit to the Distributor an irrevocable order to purchase shares of the Fund generally before 4:00 p.m., Eastern time on any Business Day to receive that day’s NAV. On days when the Listing Exchange closes earlier than normal, the Fund may require orders for Creation Units to be placed earlier in the day. The Distributor will notify BFA and the Custodian of such order. The Custodian will then provide such information to any appropriate subcustodian. Procedures and requirements governing the delivery of the Fund Deposit are set forth in the procedures handbook for Authorized Participants and may change from time to time. Those placing orders to purchase Creation Units through an Authorized Participant should allow sufficient time to permit proper submission of the purchase order to the Distributor by the Cutoff Time (as defined below) on such Business Day.

The Authorized Participant must also make available on or before the contractual settlement date, by means satisfactory to the Fund, immediately available or same day funds estimated by the Fund to be sufficient to pay the Cash Component next determined after acceptance of the purchase order, together with the applicable purchase transaction fees. Any excess funds will be returned following settlement of the issue of the Creation Unit. Those placing orders should ascertain the deadline for cash transfers by contacting the operations department of the broker or depositary institution effectuating the transfer of the Cash Component. This deadline is likely to be significantly earlier than the Cutoff Time (as described below) of the Fund.

The Authorized Participant is responsible for any and all expenses and costs incurred by the Fund, including any applicable cash amounts, in connection with any purchase order.

Investors, other than Authorized Participants, are responsible for making arrangements for a creation request to be made through an Authorized Participant. The Distributor will provide a list of current Authorized Participants upon request. Investors should be aware that an Authorized Participant may require orders for purchases of shares placed with it to be in the particular form required by the individual Authorized Participant.

Timing of Submission of Purchase Orders. An Authorized Participant must submit an irrevocable order to purchase shares of a Fund generally before 4:00 p.m., Eastern time on any Business Day in order to receive that day’s NAV. Orders to create shares of the Fund that are submitted on the Business Day immediately preceding a holiday or day (other than a weekend) when the equity markets in the relevant foreign market are closed may not be accepted. The deadline specified above for the submission of purchase orders is referred to as the Fund’s “Cutoff Time.” The Distributor in its discretion may permit the submission of such orders and requests by or through an Authorized Participant at any time (including on days on which the Listing Exchange is not open for business) via communication through the facilities of the Distributor’s proprietary website maintained for this purpose. Purchase orders and redemption requests, if accepted by the Trust, will be processed based on the NAV next determined after such acceptance in accordance with the Trust’s standard Cutoff Times as provided in the Authorized Participant Agreement and disclosed in this SAI.

Acceptance of Orders for Creation Units. Subject to the conditions that (i) an irrevocable purchase order has been submitted by the Authorized Participant (either on its own or another investor’s behalf) and (ii) arrangements satisfactory to the Fund are in place for payment of the Cash Component and any other cash amounts which may be due, the Fund will accept the order, subject to the Fund’s right (and the right of the Distributor and BFA) to reject any order until acceptance.

Once the Fund has accepted an order, upon the next determination of the net asset value of the shares, the Fund will confirm the issuance of a Creation Unit, against receipt of payment, at such net asset value. The Distributor will then transmit a confirmation of acceptance to the Authorized Participant that placed the order.

The Fund reserves the absolute right to reject or revoke a creation order transmitted to it by the Distributor if (i) the order is not in proper form; (ii) the investor(s), upon obtaining the shares ordered, would own 80% or more of the currently outstanding shares of the Fund; (iii) the Deposit Securities delivered do not conform to the identity and number of shares specified, as described above; (iv) acceptance of the Deposit Securities would have certain adverse tax consequences to the Fund; (v) acceptance of the Fund Deposit would, in the opinion of counsel, be unlawful; (vi) acceptance of the Fund Deposit would, in the discretion of the Fund or BFA, have an adverse effect on the Fund or the rights of beneficial owners; or (vii) circumstances outside the control of the Fund, the Distributor and BFA make it impracticable to process purchase orders. The Distributor shall notify a prospective purchaser of a Creation Unit and/or the Authorized Participant acting on behalf of such purchaser of its rejection of such order. The Fund, State Street, the subcustodian and the Distributor are under no duty, however, to give notification of any defects or irregularities in the delivery of Portfolio Deposits nor shall any of them incur any liability for failure to give such notification.

Issuance of a Creation Unit. Except as provided herein, a Creation Unit will not be issued until the transfer of good title to the Fund of the Deposit Securities and the payment of the Cash Component have been completed. When the subcustodian has confirmed to the Custodian that the securities included in the Fund Deposit (or the cash value thereof) have been delivered to the account of the relevant subcustodian or subcustodians, the Distributor and BFA shall be notified of such delivery and the Fund will issue and cause the delivery of the Creation Unit. Creation Units typically are issued on a “T+3 basis” (i.e., three Business Days after trade date). However, as discussed in the Regular Holidays section, the Fund reserves the right to settle Creation Unit transactions on a basis other than T+3 in order to accommodate non-U.S. market holiday schedules, to account for different treatment among non-U.S. and U.S. markets of dividend record dates and ex-dividend dates (i.e., the last day the holder of a security can sell the security and still receive dividends payable on the security) and in certain other circumstances.

To the extent contemplated by an Authorized Participant’s agreement with the Distributor, the Fund will issue Creation Units to such Authorized Participant, notwithstanding the fact that the corresponding Portfolio Deposits have not been received in part or in whole, in reliance on the undertaking of the Authorized Participant to deliver the missing Deposit Securities as soon as possible, which undertaking shall be secured by such Authorized Participant’s delivery and maintenance of collateral having a value at least equal to 105% and up to 115%, which percentage BFA may change from time to time, of the value of the missing Deposit Securities in accordance with the Fund’s then-effective procedures. The only collateral that is acceptable to the Fund is cash in U.S. dollars. Such cash collateral must be delivered no later than 2:00 p.m., Eastern time on the contractual settlement date. The cash collateral posted by the Authorized Participant may be invested at the risk of the Authorized Participant, and income, if any, on invested cash collateral will be paid to that Authorized Participant. Information concerning the Fund’s current procedures for collateralization of missing Deposit Securities is available from the Distributor. The Authorized Participant Agreement will permit the Fund to buy the missing Deposit Securities at any time and will subject the Authorized Participant to liability for any shortfall between the cost to the Fund of purchasing such securities and the cash collateral.

In certain cases, Authorized Participants may create and redeem Creation Units on the same trade date and in these instances, the Fund reserves the right to settle these transactions on a net basis or require a representation from the Authorized Participants that the creation and redemption transactions are for separate beneficial owners. All questions as to the number of shares of each security in the Deposit Securities and the validity, form, eligibility and acceptance for deposit of any securities to be delivered shall be determined by the Fund and the Fund’s determination shall be final and binding.

Cash Purchase Method. Although the Trust does not ordinarily permit cash purchases of Creation Units of iShares funds, when Creation Units are available or specified for the Fund, they will be effected in essentially the same manner as in-kind purchases thereof. In the case of a cash purchase, the Authorized Participant must pay the cash equivalent of the Deposit Securities it would otherwise be required to provide through an in-kind purchase, plus the same Cash Component required to be paid by an in-kind purchaser.

Costs Associated with Creation Transactions. A standard creation transaction fee is imposed to offset the transfer and other transaction costs associated with the issuance of Creation Units. The standard creation transaction fee will be the same regardless of the number of Creation Units purchased by an Authorized Participant on the applicable Business Day. The

Authorized Participant may also be required to cover certain brokerage, tax, foreign exchange, execution, market impact and other costs and expenses related to the execution of trades resulting from such transaction (up to the maximum amount shown below). Authorized Participants will also bear the costs of transferring the Deposit Securities to the Fund. Investors who use the services of a broker or other financial intermediary may be charged a fee for such services.

The following table sets forth the Fund’s standard creation transaction fees and maximum additional charge (as described above):

Standard Creation
Transaction Fee
Maximum Additional
Charge for Creations*
$15,000 3.0%

* As a percentage of the net asset value per Creation Unit.
Redemption of Creation Units. Shares of the Fund may be redeemed by Authorized Participants only in Creation Units at their NAV next determined after receipt of a redemption request in proper form by the Distributor and only on a Business Day. The Fund will not redeem shares in amounts less than Creation Units. There can be no assurance, however, that there will be sufficient liquidity in the secondary market at any time to permit assembly of a Creation Unit. Investors should expect to incur brokerage and other costs in connection with assembling a sufficient number of shares to constitute a Creation Unit that could be redeemed by an Authorized Participant. Beneficial owners also may sell shares in the secondary market.

BFA makes available through the NSCC, prior to the opening of business on the Listing Exchange on each Business Day, the designated portfolio of securities (including any portion of such securities for which cash may be substituted) that will be applicable (subject to possible amendment or correction) to redemption requests received in proper form (as defined below) on that day (“Fund Securities”), and an amount of cash (as described below). Such Fund Securities and the corresponding cash amount are applicable, subject to any adjustments as described below, in order to effect redemptions of Creation Units of the Fund until such time as the next announced composition of the Fund Securities is made available. Fund Securities received on redemption may not be identical to Deposit Securities that are applicable to creations of Creation Units.

Unless cash redemptions are available or specified for the Fund, the redemption proceeds for a Creation Unit generally consist of Fund Securities, plus additional cash in an amount equal to the difference between the net asset value of the shares being redeemed, as next determined after the receipt of a request in proper form, and the value of Fund Securities, less a redemption transaction fee (as described below). The Trust may, in its sole discretion, substitute a “cash in lieu” amount to replace any Fund Security. The amount of cash paid out in such cases will be equivalent to the value of the substituted security listed as a Fund Security. In the event that the Fund Securities have a value greater than the NAV of the shares, a compensating cash payment equal to the difference is required to be made by or through an Authorized Participant by the redeeming shareholder. The Fund currently redeems shares for Fund Securities, but the Fund reserves the right to utilize a cash option for redemption of shares.

Costs Associated with Redemption Transactions. A standard redemption transaction fee is imposed to offset transfer and other transaction costs that may be incurred by the Fund. The standard redemption transaction fee will be the same regardless of the number of Creation Units redeemed by an Authorized Participant on the applicable Business Day. The Authorized Participant may also be required to cover certain brokerage, tax, foreign exchange, execution, market impact and other costs and expenses related to the execution of trades resulting from such transaction (up to the maximum amount shown below). Authorized Participants will also bear the costs of transferring the Fund Securities from the Fund to their account on their order. Investors who use the services of a broker or other financial intermediary may be charged a fee for such services.

The following table sets forth the Fund’s standard redemption transaction fees and maximum additional charge (as described above):

Standard Redemption
Transaction Fee
Maximum Additional
Charge for Redemptions*
$15,000 2.0%

* As a percentage of the net asset value per Creation Unit, inclusive of the standard redemption transaction fee.

Placement of Redemption Orders. Redemption requests for Creation Units of the Fund must be submitted to the Distributor by or through an Authorized Participant. An Authorized Participant must submit an irrevocable request to redeem shares of a Fund generally before 4:00 p.m., Eastern time on any Business Day, in order to receive that day’s NAV. Orders to redeem shares of each Fund that are submitted on the Business Day immediately preceding a holiday or day (other than a weekend) when the equity markets in the relevant foreign market are closed may not be accepted. Investors other than Authorized Participants are responsible for making arrangements for a redemption request to be made through an Authorized Participant. The Distributor will provide a list of current Authorized Participants upon request.

The Authorized Participant must transmit the request for redemption in the form required by the Fund to the Distributor in accordance with procedures set forth in the Authorized Participant Agreement. Investors should be aware that their particular broker may not have executed an Authorized Participant Agreement and that, therefore, requests to redeem Creation Units may have to be placed by the investor’s broker through an Authorized Participant who has executed an Authorized Participant Agreement. At any time, only a limited number of broker-dealers will have an Authorized Participant Agreement in effect. Investors making a redemption request should be aware that such request must be in the form specified by such Authorized Participant. Investors making a request to redeem Creation Units should allow sufficient time to permit proper submission of the request by an Authorized Participant and transfer of the shares to the Fund’s Transfer Agent; such investors should allow for the additional time that may be required to effect redemptions through their banks, brokers or other financial intermediaries if such intermediaries are not Authorized Participants.

A redemption request is considered to be in “proper form” if (i) an Authorized Participant has transferred or caused to be transferred to the Fund’s Transfer Agent the Creation Unit being redeemed through the book-entry system of DTC so as to be effective by the Listing Exchange closing time on any Business Day, (ii) a request in form satisfactory to the Fund is received by the Distributor from the Authorized Participant on behalf of itself or another redeeming investor within the time periods specified above and (iii) all other procedures set forth in the Authorized Participant Agreement are properly followed. If the Transfer Agent does not receive the investor’s shares through DTC’s facilities by 10:00 a.m., Eastern time on the Business Day next following the day that the redemption request is received, the redemption request shall be rejected. Investors should be aware that the deadline for such transfers of shares through the DTC system may be significantly earlier than the close of business on the Listing Exchange. Those making redemption requests should ascertain the deadline applicable to transfers of shares through the DTC system by contacting the operations department of the broker or depositary institution effecting the transfer of the shares.

Upon receiving a redemption request, the Distributor shall notify the Fund and the Fund’s Transfer Agent of such redemption request. The tender of an investor’s shares for redemption and the distribution of the securities and/or cash included in the redemption payment made in respect of Creation Units redeemed will be made through DTC and the relevant Authorized Participant to the Beneficial Owner thereof as recorded on the book-entry system of DTC or the DTC Participant through which such investor holds, as the case may be, or by such other means specified by the Authorized Participant submitting the redemption request.

A redeeming Beneficial Owner or Authorized Participant acting on behalf of such Beneficial Owner must maintain appropriate security arrangements with a qualified broker-dealer, bank or other custody providers in each jurisdiction in which any of the Portfolio Securities are customarily traded, to which account such Portfolio Securities will be delivered.

Deliveries of redemption proceeds by the Fund generally will be made within three Business Days (i.e., “T+3”). However, as discussed in the Regular Holidays section, the Fund reserves the right to settle redemption transactions and deliver redemption proceeds on another basis to accommodate non-U.S. market holiday schedules, to account for different treatment among non-U.S. and U.S. markets of dividend record dates and dividend ex-dates (i.e., the last date the holder of a security can sell the security and still receive dividends payable on the security sold) and in certain other circumstances. The Regular Holidays section hereto identifies the instances, if any, where more than seven days would be needed to deliver redemption proceeds. Pursuant to an order of the SEC, the Trust will make delivery of redemption proceeds within the number of days stated in the Regular Holidays section to be the maximum number of days necessary to deliver redemption proceeds.


If neither the redeeming Beneficial Owner nor the Authorized Participant acting on behalf of such redeeming Beneficial Owner has appropriate arrangements to take delivery of Fund Securities in the applicable non-U.S. jurisdiction and it is not possible to make other such arrangements, or if it is not possible to effect deliveries of Fund Securities in such jurisdiction,

the Trust may in its discretion exercise its option to redeem such shares in cash, and the redeeming Beneficial Owner will be required to receive its redemption proceeds in cash. In such case, the investor will receive a cash payment equal to the net asset value of its shares based on the NAV of the Fund next determined after the redemption request is received in proper form (minus a redemption transaction fee and additional charges specified above to offset the Trust’s brokerage and other transaction costs associated with the disposition of Fund Securities). Redemptions of shares for Fund Securities will be subject to compliance with applicable U.S. federal and state securities laws and the Fund (whether or not it otherwise permits cash redemptions) reserves the right to redeem Creation Units for cash to the extent that the Fund cannot lawfully deliver specific Fund Securities upon redemptions or cannot do so without first registering the Fund Securities under such laws.


Although the Trust does not ordinarily permit cash redemptions of Creation Units, in the event that cash redemptions are permitted or required by the Trust, proceeds will be paid to the Authorized Participant redeeming shares as soon as practicable after the date of redemption (within seven calendar days thereafter, except for the instances listed in the Regular Holidays section in which more than seven calendar days would be needed).

To the extent contemplated by an Authorized Participant’s agreement with the Distributor, in the event an Authorized Participant has submitted a redemption request in proper form but is unable to transfer all or part of the Creation Unit to be redeemed to the Fund, at or prior to 10:00 a.m., Eastern time on the Listing Exchange business day after the date of submission of such redemption request, the Distributor will accept the redemption request in reliance on the undertaking by the Authorized Participant to deliver the missing shares as soon as possible. Such undertaking shall be secured by the Authorized Participant’s delivery and maintenance of collateral consisting of cash, in U.S. dollars in immediately available funds, having a value at least equal to 105% and up to 115%, which percentage BFA may change from time to time, of the value of the missing shares. Such cash collateral must be delivered no later than 10:00 a.m., Eastern time on the day after the date of submission of such redemption request and shall be held by State Street and marked-to-market daily. The fees of State Street and any subcustodians in respect of the delivery, maintenance and redelivery of the cash collateral shall be payable by the Authorized Participant. The cash collateral posted by the Authorized Participant may be invested at the risk of the Authorized Participant, and income, if any, on invested cash collateral will be paid to that Authorized Participant. The Authorized Participant Agreement permits the Fund to acquire Fund Securities and the Cash Component underlying such shares at any time and subjects the Authorized Participant to liability for any shortfall between the cost to the Fund of purchasing such shares, Fund Securities or Cash Component and the value of the cash collateral.

Because the Portfolio Securities of the Fund may trade on exchange(s) on days that the Listing Exchange is closed or are otherwise not Business Days for the Fund, shareholders may not be able to redeem their shares of the Fund, or purchase or sell shares of the Fund on the Listing Exchange on days when the NAV of the Fund could be significantly affected by events in the relevant non-U.S. markets.

The right of redemption may be suspended or the date of payment postponed with respect to the Fund (i) for any period during which the Listing Exchange is closed (other than customary weekend and holiday closings), (ii) for any period during which trading on the Listing Exchange is suspended or restricted, (iii) for any period during which an emergency exists as a result of which disposal of the shares of the Fund’s portfolio securities or determination of its net asset value is not reasonably practicable; or (iv) in such other circumstance as is permitted by the SEC.

Taxation on Creation and Redemptions of Creation Units. An Authorized Participant generally will recognize either gain or loss upon the exchange of Deposit Securities for Creation Units. This gain or loss is calculated by taking the market value of the Creation Units purchased over the Authorized Participant’s aggregate basis in the Deposit Securities exchanged therefor. However, the U.S. Internal Revenue Service (the “IRS”) may apply the wash sales rules to determine that any loss realized upon the exchange of Deposit Securities for Creation Units is not currently deductible. Authorized Participants should consult their own tax advisors.

Current U.S. federal tax laws dictate that capital gain or loss realized from the redemption of Creation Units will generally create long-term capital gain or loss if the Authorized Participant holds the Creation Units for more than one year, or short-term capital gain or loss if the Creation Units were held for one year or less, if the Creation Units are held as capital assets.

Regular Holidays. For every occurrence of one or more intervening holidays in the applicable non-U.S. market that are not holidays observed in the U.S. equity market, the redemption settlement cycle will be extended by the number of such intervening holidays. In addition to holidays, other unforeseeable closings in a non-U.S. market due to emergencies may also prevent the Trust from delivering securities within normal settlement period.

The securities delivery cycles currently practicable for transferring portfolio securities to redeeming investors, coupled with non-U.S. market holiday schedules, will require a delivery process longer than seven calendar days, in certain circumstances. The holidays applicable to the Fund during such periods are listed below, as are instances where more than seven days will be needed to deliver redemption proceeds. Although certain holidays may occur on different dates in subsequent years, the number of days required to deliver redemption proceeds in any given year is not expected to exceed the maximum number of days listed below for the Fund. The proclamation of new holidays, the treatment by market participants of certain days as “informal holidays” (e.g., days on which no or limited securities transactions occur, as a result of substantially shortened trading hours), the elimination of existing holidays, or changes in local securities delivery practices, could affect the information set forth herein at some time in the future.

In calendar years 2011 and 2012, the dates of regular holidays affecting the relevant securities markets in which the Fund invests are as follows (please note these holiday schedules are subject to potential changes in the relevant securities markets):

Taxes

Regulated Investment Company Qualifications. The Fund intends to continue to qualify for treatment as a separate RIC under Subchapter M of the Internal Revenue Code. To qualify for treatment as a RIC, the Fund must annually distribute at least 90% of its investment company taxable income (which includes dividends, interest and net short-term capital gains) and meet several other requirements. Among such other requirements are the following: (i) at least 90% of the Fund’s annual gross income must be derived from dividends, interest, payments with respect to securities loans, gains from the sale or other disposition of stock or securities or non-U.S. currencies, other income (including, but not limited to, gains from options, futures or forward contracts) derived with respect to its business of investing in such stock, securities or currencies, and net income derived from interests in qualified publicly-traded partnerships (i.e., partnerships that are traded on an established securities market or tradable on a secondary market, other than partnerships that derive 90% of their income from interest, dividends, capital gains and other traditionally permitted mutual fund income); and (ii) at the close of each quarter of the Fund’s taxable year, (a) at least 50% of the market value of the Fund’s total assets must be represented by cash and cash items, U.S. government securities, securities of other RICs and other securities, with such other securities limited for purposes of this calculation in respect of any one issuer to an amount not greater than 5% of the value of the Fund’s assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of the Fund’s total assets may be invested in the securities (other than U.S. government securities or the securities of other RICs) of any one issuer, of two or more issuers of which 20% or more of the voting stock is held by the Fund and that are engaged in the same or similar trades or businesses or related trades or businesses, or the securities of one or more qualified publicly-traded partnerships.

Although, in general, the passive loss rules of the Internal Revenue Code do not apply to RICs, such rules do apply to a RIC with respect to items attributable to interests in qualified publicly-traded partnerships. The Fund’s investments in partnerships, including in qualified publicly-traded partnerships, may result in the Fund being subject to state, local, or non-U.S. income, franchise or withholding tax liabilities.

Taxation of RICs. As a RIC, the Fund will not be subject to U.S. federal income tax on the portion of its taxable investment income and capital gains that it distributes to its shareholders, provided that it satisfies a minimum distribution requirement. To satisfy the minimum distribution requirement, the Fund must distribute to its shareholders at least the sum of (i) 90% of its “investment company taxable income” (i.e., income other than its net realized long-term capital gain over its net realized short-term capital loss), plus or minus certain adjustments, and (ii) 90% of its net tax-exempt income for the taxable year. The Fund will be subject to income tax at regular corporate rates on any taxable income or gains that it does not distribute to its shareholders. If the Fund fails to qualify for any taxable year as a RIC or fails to meet the distribution requirement, all of its taxable income will be subject to tax at regular corporate income tax rates without any deduction for distributions to shareholders, and such distributions generally will be taxable to shareholders as ordinary dividends to the extent of the Fund’s current and accumulated earnings and profits. In such event, distributions to individuals should be eligible to be treated as qualified dividend income and distributions to corporate shareholders generally should be eligible for the dividends received deduction. Although the Fund intends to distribute substantially all of its net investment income and its capital gains for each taxable year, the Fund will be subject to U.S. federal income taxation to the extent any such income or gains are not distributed. If the Fund fails to qualify as a RIC in any year, it must pay out its earnings and profits accumulated in that year in order to qualify again as a RIC. If the Fund fails to qualify as a RIC for a period greater than two taxable years, the Fund may be required to recognize any net built-in gains with respect to certain of its assets (i.e., the excess of the aggregate gains, including items of income, over aggregate losses that would have been realized with respect to such assets if the Fund had been liquidated) if it qualifies as a RIC in a subsequent year.

Excise Tax. The Fund will be subject to a 4% excise tax on certain undistributed income if it does not distribute to its shareholders in each calendar year at least 98% of its ordinary income for the calendar year plus 98.2% of its capital gain net income for the 12 months ended October 31 of such year. For this purpose, however, any ordinary income or capital gain net income retained by the Fund that is subject to corporate income tax will be considered to have been distributed by year-end. In addition, the minimum amounts that must be distributed in any year to avoid the excise tax will be increased or decreased to reflect any underdistribution or overdistribution, as the case may be, from the previous year. The Fund intends to declare and distribute dividends and distributions in the amounts and at the times necessary to avoid the application of this 4% excise tax.

Net Capital Loss Carryforwards. Net capital loss carryforwards may be applied against any net realized capital gains in each succeeding year, until they have been reduced to zero or until their respective expiration dates, whichever occurs first. Capital loss carryforwards from taxable years beginning after December 2010 are not subject to expiration.

The Fund had tax basis net capital loss carryforwards as of July 31, 2011, the tax year-end for the Fund:

Taxation of U.S. Shareholders. Dividends and other distributions by the Fund are generally treated under the Internal Revenue Code as received by the shareholders at the time the dividend or distribution is made. However, any dividend or distribution declared by the Fund in October, November or December of any calendar year and payable to shareholders of record on a specified date in such a month shall be deemed to have been received by each shareholder on December 31 of such calendar year and to have been paid by the Fund not later than such December 31, provided such dividend is actually paid by the Fund during January of the following calendar year.

The Fund intends to distribute annually to its shareholders substantially all of its investment company taxable income and any net realized long-term capital gains in excess of net realized short-term capital losses (including any capital loss carryovers). However, if the Fund retains for investment an amount equal to all or a portion of its net long-term capital gains in excess of its net short-term capital losses (including any capital loss carryovers), it will be subject to a corporate tax (currently at a maximum rate of 35%) on the amount retained. In that event, the Fund will designate such retained amounts as undistributed capital gains in a notice to its shareholders who (a) will be required to include in income for U.S. federal income tax purposes, as long-term capital gains, their proportionate shares of the undistributed amount, (b) will be entitled to credit their proportionate shares of the 35% tax paid by the Fund on the undistributed amount against their U.S. federal income tax liabilities, if any, and to claim refunds to the extent their credits exceed their liabilities, if any, and (c) will be entitled to increase their tax basis, for U.S. federal income tax purposes, in their shares by an amount equal to 65% of the amount of undistributed capital gains included in the shareholder’s income. Organizations or persons not subject to U.S. federal income tax on such capital gains will be entitled to a refund of their pro rata share of such taxes paid by the Fund upon filing appropriate returns or claims for refund with the IRS.

Distributions of net realized long-term capital gains, if any, that the Fund reports as capital gains dividends are taxable as long-term capital gains, whether paid in cash or in shares and regardless of how long a shareholder has held shares of the Fund.  Such dividends will not be eligible for the dividends received deduction. All other dividends of the Fund (including dividends from short-term capital gains) from its current and accumulated earnings and profits (“regular dividends”) are generally subject to tax as ordinary income, subject to the discussion of qualified dividend income below.

If an individual receives a regular dividend qualifying for the long-term capital gains rates and such dividend constitutes an “extraordinary dividend,” and the individual subsequently recognizes a loss on the sale or exchange of stock in respect of which the extraordinary dividend was paid, then the loss will be long-term capital loss to the extent of such extraordinary dividend. An “extraordinary dividend” on common stock for this purpose is generally a dividend (i) in an amount greater than or equal to 10% of the taxpayer’s tax basis (or trading value) in a share of stock, aggregating dividends with ex-dividend dates within an 85-day period, or (ii) in an amount greater than 20% of the taxpayer’s tax basis (or trading value) in a share of stock, aggregating dividends with ex-dividend dates within a 365-day period.

Distributions in excess of the Fund’s current and accumulated earnings and profits will, as to each shareholder, be treated as a tax-free return of capital to the extent of a shareholder’s basis in shares of the Fund, and as a capital gain thereafter (if the shareholder holds shares of the Fund as capital assets). Shareholders receiving dividends or distributions in the form of additional shares should be treated for U.S. federal income tax purposes as receiving a distribution in an amount equal to the amount of money that the shareholders receiving cash dividends or distributions will receive and should have a cost basis in the shares received equal to such amount. Dividends paid by the Fund that are attributable to dividends received by the Fund from domestic corporations may qualify for the federal dividends received deduction for corporations.

Beginning in 2013, a 3.8% U.S. federal Medicare contribution tax will be imposed on net investment income, including interest, dividends, and capital gain, of U.S. individuals with income exceeding $200,000 (or $250,000 if married and filing jointly), and of estates and trusts.

Investors considering buying shares just prior to a dividend or capital gain distribution should be aware that, although the price of shares purchased at that time may reflect the amount of the forthcoming distribution, such dividend or distribution may nevertheless be taxable to them. If the Fund is the holder of record of any security on the record date for any dividends payable with respect to such security, such dividends will be included in the Fund’s gross income not as of the date received but as of the later of (a) the date such security became ex-dividend with respect to such dividends (i.e., the date on which a buyer of the security would not be entitled to receive the declared, but unpaid, dividends); or (b) the date the Fund acquired such security. Accordingly, in order to satisfy its income distribution requirements, the Fund may be required to pay dividends based on anticipated earnings, and shareholders may receive dividends in an earlier year than would otherwise be the case.

In certain situations, the Fund may, for a taxable year, defer all or a portion of its capital losses and currency losses realized after October and certain ordinary losses realized after December until the next taxable year in computing its investment company taxable income and net capital gain, which will defer the recognition of such realized losses. Such deferrals and other rules regarding gains and losses realized after October (or December) may affect the tax character of shareholder distributions.

Sales of Shares. Upon the sale or exchange of shares of the Fund, a shareholder will realize a taxable gain or loss equal to the difference between the amount realized and the shareholder’s basis in shares of the Fund. A redemption of shares by the Fund will be treated as a sale for this purpose. Such gain or loss will be treated as capital gain or loss if the shares are capital assets in the shareholder’s hands and will be long-term capital gain or loss if the shares are held for more than one year and short-term capital gain or loss if the shares are held for one year or less. Any loss realized on a sale or exchange will be disallowed to the extent the shares disposed of are replaced, including replacement through the reinvesting of dividends and capital gains distributions in the Fund, within a 61-day period beginning 30 days before and ending 30 days after the disposition of the shares. In such a case, the basis of the shares acquired will be increased to reflect the disallowed loss. Any loss realized by a shareholder on the sale of Fund shares held by the shareholder for six months or less will be treated for U.S. federal income tax purposes as a long-term capital loss to the extent of any distributions or deemed distributions of long-term capital gains received by the shareholder with respect to such share. The Medicare contribution tax described above will apply to the sale of Fund shares.

If a shareholder incurs a sales charge in acquiring shares of the Fund, disposes of those shares within 90 days and then, on or before January 31 of the following calendar year, acquires shares in a mutual fund for which the otherwise applicable sales charge is reduced by reason of a reinvestment right (e.g., an exchange privilege), the original sales charge will not be taken into account in computing gain/loss on the original shares to the extent the subsequent sales charge is reduced. Instead, the disregarded portion of the original sales charge will be added to the tax basis of the newly acquired shares. Furthermore, the same rule also applies to a disposition of the newly acquired shares made within 90 days of the second acquisition. This provision prevents shareholders from immediately deducting the sales charge by shifting their investments within a family of mutual funds.

Back-Up Withholding. In certain cases, the Fund will be required to withhold at the applicable withholding rate, and remit to the U.S. Treasury such amounts withheld from any distributions paid to a shareholder who: (i) has failed to provide a correct taxpayer identification number; (ii) is subject to back-up withholding by the IRS; (iii) has failed to certify to the Fund that such shareholder is not subject to back-up withholding; or (iv) has not certified that such shareholder is a U.S. person (including a U.S. resident alien). Back-up withholding is not an additional tax and any amount withheld may be credited against a shareholder’s U.S. federal income tax liability.

Sections 351 and 362. The Trust, on behalf of the Fund, has the right to reject an order for a purchase of shares of the Fund if the purchaser (or group of purchasers) would, upon obtaining the shares so ordered, own 80% or more of the outstanding shares of the Fund and if, pursuant to Sections 351 and 362 of the Internal Revenue Code, the Fund would have a basis in the securities different from the market value of such securities on the date of deposit. If the Fund’s basis in such securities on the date of deposit was less than market value on such date, the Fund, upon disposition of the securities, would recognize more taxable gain or less taxable loss than if its basis in the securities had been equal to market value. It is not anticipated that the Trust will exercise the right of rejection except in a case where the Trust determines that accepting the order could result in material adverse tax consequences to the Fund or its shareholders. The Trust also has the right to require information necessary to determine beneficial share ownership for purposes of the 80% determination.


Taxation of Certain Derivatives. The Fund’s transactions in zero coupon securities, non-U.S. currencies, forward contracts, options and futures contracts (including options and futures contracts on non-U.S. currencies), to the extent permitted, will be subject to special provisions of the Internal Revenue Code (including provisions relating to “hedging transactions” and “straddles”) that, among other things, may affect the character of gains and losses realized by the Fund (i.e., may affect whether gains or losses are ordinary or capital), accelerate recognition of income to the Fund and defer Fund losses. These rules could therefore affect the character, amount and timing of distributions to shareholders. These provisions also (a) will require the Fund to mark-to-market certain types of the positions in its portfolio (i.e., treat them as if they were closed out at the end of each year) and (b) may cause the Fund to recognize income without receiving cash with which to pay dividends or make distributions in amounts necessary to satisfy the distribution requirements for avoiding income and excise taxes. The Fund will monitor its transactions, will make the appropriate tax elections and will make the appropriate entries in its books and records when it acquires any zero coupon security, non-U.S. currency, forward contract, option, futures contract or hedged investment in order to mitigate the effect of these rules and prevent disqualification of the Fund as a RIC.

The Fund’s investments in so-called “Section 1256 contracts,” such as regulated futures contracts, most non-U.S. currency forward contracts traded in the interbank market and options on most security indexes, are subject to special tax rules. All Section 1256 contracts held by the Fund at the end of its taxable year are required to be marked to their market value, and any unrealized gain or loss on those positions will be included in the Fund’s income as if each position had been sold for its fair market value at the end of the taxable year. The resulting gain or loss will be combined with any gain or loss realized by the Fund from positions in Section 1256 contracts closed during the taxable year. Provided such positions were held as capital assets and were not part of a “hedging transaction” nor part of a “straddle,” 60% of the resulting net gain or loss will be treated as long-term capital gain or loss, and 40% of such net gain or loss will be treated as short-term capital gain or loss, regardless of the period of time the positions were actually held by the Fund.

As a result of entering into swap contracts, the Fund may make or receive periodic net payments. The Fund may also make or receive a payment when a swap is terminated prior to maturity through an assignment of the swap or other closing transaction. Periodic net payments will generally constitute ordinary income or deductions, while termination of a swap will generally result in capital gain or loss (which will be a long-term capital gain or loss if the Fund has been a party to the swap for more than one year). With respect to certain types of swaps, the Fund may be required to currently recognize income or loss with respect to future payments on such swaps or may elect under certain circumstances to mark such swaps to market annually for tax purposes as ordinary income or loss.

Qualified Dividend Income. Distributions by the Fund of investment company taxable income (including any short-term capital gains), whether received in cash or shares, will be taxable either as ordinary income or as qualified dividend income, eligible for the reduced maximum rate to individuals of 15% (0% for individuals in lower tax brackets) to the extent the Fund receives qualified dividend income on the securities it holds and the Fund reports the distribution as qualified dividend income. Qualified dividend income is, in general, dividend income from taxable U.S. corporations (but generally not from U.S. REITs) and certain non-U.S. corporations (e.g., non-U.S. corporations that are not “passive foreign investment companies” and which are incorporated in a possession of the United States or in certain countries with a comprehensive tax treaty with the United States, or the stock of which is readily tradable on an established securities market in the United States (where the dividends are paid with respect to such stock)). Under current IRS guidance, the United States has appropriate comprehensive income tax treaties with the following countries: Australia, Austria, Bangladesh, Barbados, Belgium, Bulgaria, Canada, China, Cyprus, the Czech Republic, Denmark, Egypt, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, India, Indonesia, Ireland, Israel, Italy, Jamaica, Japan, Kazakhstan, Latvia, Lithuania, Luxembourg, Malta, Mexico, Morocco, the Netherlands, New Zealand, Norway, Pakistan, the Philippines, Poland, Portugal, Romania, Russia, the Slovak Republic, Slovenia, South Africa, South Korea, Spain, Sri Lanka, Sweden, Switzerland, Thailand, Trinidad and Tobago, Tunisia, Turkey, Ukraine, the United Kingdom, and Venezuela. Substitute payments received by the Fund for securities lent out by the Fund will not be qualified dividend income.

A dividend from the Fund will not be treated as qualified dividend income to the extent that (i) the shareholder has not held the shares on which the dividend was paid for 61 days during the 121-day period that begins on the date that is 60 days before the date on which the shares become ex-dividend with respect to such dividend or the Fund fails to satisfy those holding period requirements with respect to the securities it holds that paid the dividends distributed to the shareholder (or, in the case of certain preferred stocks, the holding requirement of 91 days during the 181-day period beginning on the date that is 90 days before the date on which the stock becomes ex-dividend with respect to such dividend); (ii) the Fund or the shareholder is under an obligation (whether pursuant to a short sale or otherwise) to make related payments with respect to substantially similar or related property; or (iii) the shareholder elects to treat such dividend as investment income under

Section 163(d)(4)(B) of the Internal Revenue Code. Dividends received by the Fund from a REIT or another RIC may be treated as qualified dividend income only to the extent the dividend distributions are attributable to qualified dividend income received by such REIT or other RIC. It is expected that dividends received by the Fund from a REIT and distributed to a shareholder generally will be taxable to the shareholder as ordinary income. The maximum 15% rate on qualified dividend income will not apply to dividends received in taxable years beginning after December 31, 2012. Distributions by the Fund of its net short-term capital gains will be taxable as ordinary income. Capital gain distributions consisting of the Fund’s net capital gains will be taxable as long-term capital gains.

If you lend your Fund shares pursuant to securities lending arrangements, you may lose the ability to use non-U.S. tax credits passed through by the Fund or to treat Fund dividends (paid while the shares are held by the borrower) as qualified dividends. Consult your financial intermediary or tax advisor. If you enter into a short sale with respect to shares of the Fund, substitute payments made to the lender of such shares may not be deductible. Consult your financial intermediary or tax advisor.

Corporate Dividends Received Deduction. Dividends paid by the Fund that are attributable to dividends received by the Fund from U.S. corporations may qualify for the U.S. federal dividends received deduction for corporations. A 46-day minimum holding period during the 90-day period that begins 45 days prior to ex-dividend date (or 91-day minimum holding period during the 180 period beginning 90 days prior to ex-dividend date for certain preference dividends) during which risk of loss may not be diminished is required for the applicable shares, at both the Fund and shareholder level, for a dividend to be eligible for the dividends received deduction. Restrictions may apply if indebtedness, including a short sale, is attributable to the investment.

Excess Inclusion Income. Under current law, the Fund will block unrelated business taxable income from being realized by its tax-exempt shareholders. Notwithstanding the foregoing, a tax-exempt shareholder could realize unrelated business taxable income by virtue of its investment in the Fund if shares in the Fund constitute debt-financed property in the hands of the tax-exempt shareholder within the meaning of Section 514(b) of the Internal Revenue Code. Certain types of income received by the Fund from REITs, real estate mortgage investment conduits, taxable mortgage pools or other investments may cause the Fund to report some or all of its distributions as “excess inclusion income.” To Fund shareholders, such excess inclusion income may (i) constitute taxable income, as unrelated business taxable income for those shareholders who would otherwise be tax-exempt such as individual retirement accounts, 401(k) accounts, Keogh plans, pension plans and certain charitable entities; (ii) not be offset by otherwise allowable deductions for tax purposes; (iii) not be eligible for reduced U.S. withholding for non-U.S. shareholders even from tax treaty countries; and (iv) cause the Fund to be subject to tax if certain “disqualified organizations,” as defined by the Internal Revenue Code, are Fund shareholders. If a charitable remainder annuity trust or a charitable remainder unitrust (each as defined in Section 664 of the Internal Revenue Code) has unrelated business taxable income (“UBTI”) for a taxable year, a 100% excise tax on the UBTI is imposed on the trust.

Non-U.S. Investments. Under Section 988 of the Internal Revenue Code, gains or losses attributable to fluctuations in exchange rates between the time the Fund accrues income or receivables or expenses or other liabilities denominated in a non-U.S. currency and the time the Fund actually collects such income or pays such liabilities are generally treated as ordinary income or ordinary loss. In general, gains (and losses) realized on debt instruments will be treated as Section 988 gain (or loss) to the extent attributable to changes in exchange rates between the U.S. dollar and the currencies in which the instruments are denominated. Similarly, gains or losses on non-U.S. currency, non-U.S. currency forward contracts and certain non-U.S. currency options or futures contracts denominated in non-U.S currency, to the extent attributable to fluctuations in exchange rates between the acquisition and disposition dates, are also treated as ordinary income or loss unless the Fund were to elect otherwise.

The Fund may be subject to non-U.S. income taxes withheld at the source. The Fund, if permitted to do so, may elect to “pass through” to its investors the amount of non-U.S. income taxes paid by the Fund provided that the Fund held the security on the dividend settlement date and for at least 15 additional days immediately before and/or thereafter, with the result that each investor with respect to shares of the Fund held for a minimum 16-day holding period at the time of deemed distribution will (i) include in gross income, even though not actually received, the investor’s pro rata share of the Fund’s non-U.S. income taxes, and (ii) either deduct (in calculating U.S. taxable income, but only for investors who itemize their deductions on their personal tax returns) or credit (in calculating U.S. federal income tax) the investor’s pro rata share of the Fund’s non-U.S. income taxes. A non-U.S. person invested in the Fund in a year that the Fund elects to “pass through” its non-U.S. taxes may be treated as receiving additional dividend income subject to U.S. withholding tax. A non-U.S. tax credit may not exceed the investor’s U.S. federal income tax otherwise payable with respect to the investor’s non-U.S. source

income. For this purpose, shareholders must treat as non-U.S. source gross income (i) their proportionate shares of non-U.S. taxes paid by the Fund and (ii) the portion of any dividend paid by the Fund that represents income derived from non-U.S. sources; the Fund’s gain from the sale of securities will generally be treated as U.S.-source income. Certain limitations will be imposed to the extent to which the non-U.S. tax credit may be claimed.

Passive Foreign Investment Companies. If the Fund purchases shares in “passive foreign investment companies” (“PFICs”), it may be subject to U.S. federal income tax on a portion of any “excess distribution” or gain from the disposition of such shares even if such income is distributed as a taxable dividend by the Fund to its shareholders. Additional charges in the nature of interest may be imposed on the Fund in respect of deferred taxes arising from such distributions or gains.

If the Fund were to invest in a PFIC and elect to treat the PFIC as a “qualified electing fund” under the Internal Revenue Code, in lieu of the foregoing requirements, the Fund might be required to include in income each year a portion of the ordinary earnings and net capital gains of the qualified electing fund, even if not distributed to the Fund, and such amounts would be subject to the 90% and excise tax distribution requirements described above. In order to make this election, the Fund would be required to obtain certain annual information from the PFICs in which it invests, which may be difficult or impossible to obtain.

Alternatively, the Fund may make a mark-to-market election that would result in the Fund being treated as if it had sold and repurchased its PFIC stock at the end of each year. In such case, the Fund would report any such gains as ordinary income and would deduct any such losses as ordinary losses to the extent of previously recognized gains. The election must be made separately for each PFIC owned by the Fund and, once made, would be effective for all subsequent taxable years, unless revoked with the consent of the IRS. By making the election, the Fund could potentially ameliorate the adverse tax consequences with respect to its ownership of shares in a PFIC, but in any particular year may be required to recognize income in excess of the distributions it receives from PFICs and its proceeds from dispositions of PFIC stock. The Fund may have to distribute this “phantom” income and gain to satisfy the 90% distribution requirement and to avoid imposition of the 4% excise tax.

The Fund will make the appropriate tax elections, if possible, and take any additional steps that are necessary to mitigate the effects of these rules.

Reporting. If a shareholder recognizes a loss with respect to the Fund’s shares of $2 million or more for an individual shareholder or $10 million or more for a corporate shareholder, the shareholder must file with the IRS a disclosure statement on Form 8886. Direct shareholders of portfolio securities are in many cases exempted from this reporting requirement, but under current guidance, shareholders of a RIC are not exempted. The fact that a loss is reportable under these regulations does not affect the legal determination of whether the taxpayer’s treatment of the loss is proper. Shareholders should consult their tax advisors to determine the applicability of these regulations in light of their individual circumstances.

Other Taxes. Dividends, distributions and redemption proceeds may also be subject to additional state, local and non-U.S. taxes depending on each shareholder’s particular situation.

Taxation of Non-U.S. Shareholders. Dividends paid by the Fund to non-U.S. shareholders are generally subject to withholding tax at a 30% rate or a reduced rate specified by an applicable income tax treaty to the extent derived from investment income and short-term capital gains. Dividends paid by the Fund from net tax-exempt income or long-term capital gains are generally not subject to such withholding tax. In order to obtain a reduced rate of withholding, a non-U.S. shareholder will be required to provide an IRS Form W-8BEN certifying its entitlement to benefits under a treaty. The withholding tax does not apply to regular dividends paid to a non-U.S. shareholder who provides a Form W-8ECI, certifying that the dividends are effectively connected with the non-U.S. shareholder’s conduct of a trade or business within the United States. Instead, the effectively connected dividends will be subject to regular U.S. income tax as if the non-U.S. shareholder were a U.S. shareholder. A non-U.S. corporation receiving effectively connected dividends may also be subject to additional “branch profits tax” imposed at a rate of 30% (or lower treaty rate). A non-U.S. shareholder who fails to provide an IRS Form W-8BEN or other applicable form may be subject to back-up withholding at the appropriate rate.

In general, U.S. federal withholding tax will not apply to any gain or income realized by a non-U.S. shareholder in respect of any distributions of net long-term capital gains over net short-term capital losses, tax-exempt interest dividends, or upon the sale or other disposition of shares of the Fund. If the Fund’s direct or indirect interests in U.S. real property were to exceed certain levels, distributions to a non-U.S. shareholder from the Fund attributable to a REIT’s distribution to the Fund of gain from a sale or exchange of a U.S. real property interest and, in the case of a non-U.S. shareholder owning more than 5% of

the class of shares throughout either such person’s holding period for the redeemed shares or, if shorter, the previous five years, the gain on redemption will be treated as real property gain subject to additional taxes or withholding and may result in the non-U.S. shareholder having additional filing requirements.

For taxable years beginning before January 1, 2012, distributions that the Fund reports as “short-term capital gain dividends” or “long-term capital gain dividends” are not treated as such to a recipient non-U.S. shareholder if the distribution is attributable to gain received from the sale or exchange of U.S. real property or an interest in a U.S. real property holding corporation and the Fund’s direct or indirect interests in U.S. real property exceed certain levels. Instead, if the non-U.S. shareholder has not owned more than 5% of the outstanding shares of the Fund at any time during the one year period ending on the date of distribution, such distribution is subject to 30% withholding by the Fund and is treated as ordinary dividends to the non-U.S. shareholder; if the non-U.S. shareholder owned more than 5% of the outstanding shares of the Fund at any time during the one year period ending on the date of the distribution, such distribution is treated as real property gain subject to 35% withholding tax and could subject the non-U.S. shareholder to U.S. filing requirements. Additionally, if the Fund’s direct or indirect interests in U.S. real property were to exceed certain levels, a non-U.S. shareholder realizing gains upon redemption from the Fund on or before December 31, 2011 could be subject to the 35% withholding tax and U.S. filing requirements unless more than 50% of the Fund’s shares were owned by U.S. persons at such time or unless the non-U.S. person had not held more than 5% of the Fund’s outstanding shares throughout either such person’s holding period for the redeemed shares or, if shorter, the previous five years.

The rules laid out in the previous two paragraphs, other than the withholding rules, will apply notwithstanding the Fund’s participation in a wash sale transaction or its payment of a substitute dividend.

Provided that 50% or more of the value of the Fund’s stock is held by U.S. shareholders, distributions of U.S. real property interests (including securities in a U.S. real property holding corporation, unless such corporation is regularly traded on an established securities market and the Fund has held 5% or less of the outstanding shares of the corporation during the five-year period ending on the date of distribution) occurring on or before December 31, 2011, in redemption of a foreign shareholder’s shares of the Fund will cause the Fund to recognize gain. If the Fund is required to recognize gain, the amount of gain recognized will be equal to the fair market value of such interests over the Fund’s adjusted bases to the extent of the greatest foreign ownership percentage of the Fund during the five-year period ending on the date of redemption.

For taxable years beginning before January 1, 2012, properly reported dividends are generally exempt from U.S. federal withholding tax where they (i) are paid in respect of the Fund’s “qualified net interest income” (generally, the Fund’s U.S. source interest income, other than certain contingent interest and interest from obligations of a corporation or partnership in which the Fund is at least a 10% shareholder, reduced by expenses that are allocable to such income), or (ii) are paid in respect of the Fund’s “qualified short-term capital gains” (generally, the excess of the Fund’s net short-term capital gain over the Fund’s long-term capital loss for such taxable year). However, depending on its circumstances, the Fund may report all, some or none of its potentially eligible dividends as such qualified net interest income or as qualified short-term capital gains and/or treat such dividends, in whole or in part, as ineligible for this exemption from withholding. In order to qualify for this exemption from withholding, a non-U.S. shareholder will need to comply with applicable certification requirements relating to its non-U.S. status (including, in general, furnishing an IRS Form W-8BEN or substitute Form). In the case of shares held through an intermediary, the intermediary may withhold even if the Fund reports the payment as qualified net interest income or qualified short-term capital gain. Non-U.S. shareholders should contact their intermediaries with respect to the application of these rules to their accounts.

A 30% withholding tax will be imposed on dividends paid after December 31, 2013, and redemption proceeds paid after December 31, 2014, to (i) foreign financial institutions, including non-U.S. investment funds, unless they agree to collect and disclose to the IRS information regarding their direct and indirect U.S. account holders; and (ii) certain other foreign entities, unless they certify certain information regarding their direct and indirect U.S. owners. To avoid withholding, foreign financial institutions will need to enter into agreements with the IRS that state that they will provide the IRS information, including the name, address and taxpayer identification number of direct and indirect U.S. account holders; comply with due diligence procedures with respect to the identification of U.S. accounts; report to the IRS certain information with respect to U.S. accounts maintained; agree to withhold tax on certain payments made to non-compliant foreign financial institutions or to account holders who fail to provide the required information; and determine certain other information as to their account holders. Other foreign entities will need to provide the name, address, and taxpayer identification number of each substantial U.S. owner or certifications of no substantial U.S. ownership, unless certain exceptions apply.

Shares of the Fund held by a non-U.S. shareholder at death will be considered situated within the United States and subject to the U.S. estate tax for decedents dying after December 31, 2011, with a lookthrough rule applying before such date.

The foregoing discussion is a summary of certain material U.S. federal income tax considerations only and is not intended as a substitute for careful tax planning. Purchasers of shares should consult their own tax advisors as to the tax consequences of investing in such shares, including consequences under state, local and non-U.S. tax laws. Finally, the foregoing discussion is based on applicable provisions of the Internal Revenue Code, regulations, judicial authority and administrative interpretations in effect on the date of this SAI. Changes in applicable authority could materially affect the conclusions discussed above, and such changes often occur.

General Description of the Trust and its Funds

The Trust currently consists of more than 190 investment series or portfolios. The Trust was organized as a Delaware statutory trust on December 16, 1999 and is authorized to have multiple series or portfolios. The Trust is an open-end management investment company registered with the Securities and Exchange Commission (the “SEC”) under the Investment Company Act of 1940, as amended (the “1940 Act”). The offering of the Trust’s shares is registered under the Securities Act of 1933, as amended (the “1933 Act”). This SAI relates to the following Funds:

  • iShares S&P Conservative Allocation Fund
  • iShares S&P Moderate Allocation Fund
  • iShares S&P Growth Allocation Fund
  • iShares S&P Aggressive Allocation Fund
  • iShares S&P Target Date Retirement Income Index Fund
  • iShares S&P Target Date 2010 Index Fund
  • iShares S&P Target Date 2015 Index Fund
  • iShares S&P Target Date 2020 Index Fund
  • iShares S&P Target Date 2025 Index Fund
  • iShares S&P Target Date 2030 Index Fund
  • iShares S&P Target Date 2035 Index Fund
  • iShares S&P Target Date 2040 Index Fund
  • iShares S&P Target Date 2045 Index Fund
  • iShares S&P Target Date 2050 Index Fund

The investment objective of each Fund is to seek investment results that correspond generally to the price and yield performance, before fees and expenses, of a specified benchmark index (each, an “Underlying Index”and collectively, the “Underlying Indexes”). Each Underlying Index is comprised of securities of other iShares funds (“Underlying Funds”) that themselves seek investment results that correspond generally to the price and yield performance, before fees and expenses, of a specified benchmark index representing publicly-traded securities of issuers in a particular country, region, broad market, market segment, market sector or group of industries. Thus, each Fund invests in a combination of the Underlying Funds and may also invest in other exchange-traded funds (“ETFs”), U.S. government securities, short-term paper futures contracts, options on futures contracts, options, cash and cash equivalents, including shares of money market funds advised by BFA. BFA is a wholly owned subsidiary of BTC, which in turn is indirectly wholly owned by BlackRock Inc.

Each Fund offers and issues shares at their net asset value per share (“NAV”) only in aggregations of a specified number of shares (“Creation Unit”), generally in exchange for a designated portfolio of securities (including any portion of such securities for which cash may be substituted) included in its Underlying Index (the “Deposit Securities”), together with the deposit of a specified cash payment (the “Cash Component”). The shares described in the applicable Prospectus and in this SAI are listed for trading on national securities exchanges (the “Listing Exchange”) such as NYSE Arca, Inc. (“NYSE Arca”). Shares trade in the secondary market and elsewhere at market prices that may be at, above or below NAV. Shares are redeemable only in Creation Units, and, generally, in exchange for portfolio securities and a Cash Component. Creation Units typically are a specified number of shares, generally 50,000 or multiples thereof.

The Trust reserves the right to permit or require that creations and redemptions of shares are effected fully or partially in cash. Shares may be issued in advance of receipt of Deposit Securities, subject to various conditions, including a requirement to maintain with the Trust a cash deposit, equal to at least 105% and up to 115%, which percentage BFA may change from time to time, of the market value of the omitted Deposit Securities. See the Creation and Redemption of Creation Units section of this SAI. Transaction fees associated with creations or redemptions that include a cash portion may be higher than the transaction fees associated with in-kind creations or redemptions. In all cases, conditions and fees will be limited in

accordance with the requirements of SEC rules and regulations applicable to management investment companies offering redeemable securities.

Exchange Listing and Trading

A discussion of exchange listing and trading matters associated with an investment in each Fund is contained in the Shareholder Information section of each Fund’s Prospectus. The discussion below supplements, and should be read in conjunction with, that section of the applicable Prospectus.

Shares of each Fund are listed for trading, and trade throughout the day, on the Listing Exchange and other secondary markets. Shares of the Funds may also be listed on certain non-U.S. exchanges. There can be no assurance that the requirements of the Listing Exchange necessary to maintain the listing of shares of any Fund will continue to be met. The Listing Exchange may, but is not required to, remove the shares of a Fund from listing if (i) following the initial 12-month period beginning upon the commencement of trading of Fund shares, there are fewer than 50 beneficial owners of shares of the Fund for 30 or more consecutive trading days, (ii) the value of the Underlying Index on which the Fund is based is no longer calculated or available, (iii) the “indicative optimized portfolio value” (“IOPV”) of the Fund is no longer calculated or available, or (iv) any other event shall occur or condition shall exist that, in the opinion of the Listing Exchange, makes further dealings on the Listing Exchange inadvisable. The Listing Exchange will also remove shares of a Fund from listing and trading upon termination of the Fund.

As in the case of other publicly-traded securities, when you buy or sell shares through a broker you will incur a brokerage commission determined by that broker.

In order to provide additional information regarding the indicative value of shares of the Funds, the Listing Exchange or a market data vendor disseminates information every 15 seconds through the facilities of the Consolidated Tape Association, or through other widely disseminated means, an updated IOPV for the Funds as calculated by an information provider or market data vendor. The Trust is not involved in or responsible for any aspect of the calculation or dissemination of the IOPVs and makes no representation or warranty as to the accuracy of the IOPVs.

An IOPV has an equity and fixed-income securities component and a cash component. The equity and fixed-income securities values included in an IOPV are the values of the Deposit Securities for a Fund. While the IOPV reflects the current market value of the Deposit Securities required to be deposited in connection with the purchase of a Creation Unit, it does not necessarily reflect the precise composition of the current portfolio of securities held by the Fund at a particular point in time because the current portfolio of the Fund may include securities that are not a part of the current Deposit Securities. Therefore, a Fund’s IOPV disseminated during the Listing Exchange trading hours should not be viewed as a real-time update of the Fund’s NAV, which is calculated only once a day.

The cash component included in an IOPV consists of estimated accrued interest, dividends and other income, less expenses. If applicable, each IOPV also reflects changes in currency exchange rates between the U.S. dollar and the applicable currency.

The Trust reserves the right to adjust the share prices of the Funds in the future to maintain convenient trading ranges for investors. Any adjustments would be accomplished through stock splits or reverse stock splits, which would have no effect on the net assets of the Funds or an investor’s equity interest in the Funds.

Investment Strategies and Risks of the Funds

Each Fund seeks to achieve its objective by investing primarily in securities that comprise its relevant Underlying Index and through transactions that provide substantially similar exposure to securities in the Underlying Index. Each Fund operates as an index fund and will not be actively managed. Adverse performance of a security in a Fund’s portfolio will ordinarily not result in the elimination of the security from a Fund’s portfolio.

Each Fund engages in representative sampling, which is investing in a sample of securities selected by BFA to have a collective investment profile similar to that of the Fund’s Underlying Index. Securities selected have aggregate investment characteristics (based on market capitalization and industry weightings), fundamental characteristics (such as return

variability, earnings valuation and yield) and liquidity measures similar to those of the Underlying Index. Funds that use representative sampling generally do not hold all of the securities that are in their relevant Underlying Indexes.

Each Fund generally invests at least 90% of its assets in securities of its Underlying Index.

Each Fund may invest up to 25% of its total assets in the shares of a wholly owned subsidiary of the Fund formed in the Cayman Islands (each, a “Subsidiary” and together, the “Subsidiaries”). Investments in the Subsidiaries are expected to provide each Fund with exposure to investment returns of commodities within the limitations of Subchapter M of the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”) and recent Internal Revenue Service (the “IRS”) letter rulings, as discussed below. The Subsidiaries are advised by BFA. The Subsidiaries are subject to the same fundamental, non-fundamental and certain other investment restrictions as each Fund. Each Subsidiary is a company organized under the laws of the Cayman Islands, whose registered office is located at the offices of Maples Corporate Services Limited, P.O. Box 309, Ugland House, Grand Cayman KYI-1104, Cayman Islands. Each Subsidiary’s affairs are overseen by a board of directors, which is comprised of Robert S. Kapito and Michael A. Latham, each a Trustee of the Trust. Each Fund is the sole shareholder of its Subsidiary, and shares of a Subsidiary will not be sold or offered to other investors.
The Subsidiaries invest primarily in commodity-related instruments. Each Fund will gain exposure to the investment returns of commodities indirectly by investing in a Subsidiary. To the extent that BlackRock believes that such instruments provide suitable exposure to commodities, each Fund’s investment in a Subsidiary will likely increase. BlackRock manages the assets of the Subsidiaries, but receives no additional compensation for doing so.
BlackRock also provides certain administrative services for the Subsidiaries, but receives no additional compensation for doing so. The Subsidiaries will also enter into separate contracts for the provision of custody, transfer agency, and accounting agent services with the same or with affiliates of the same service providers that provide those services to each Fund.
The Subsidiaries are managed pursuant to compliance policies and procedures that are the same, in all material respects, as the policies and procedures adopted by each Fund. As a result, each Fund treats the Subsidiary’s portfolio as subject to the same investment policies and restrictions that apply to the management of the Fund, and, in particular, to the requirements relating to portfolio leverage, liquidity, brokerage, and the timing and method of the valuation of the Subsidiary’s portfolio investments and shares of the Subsidiary. These policies and restrictions are described elsewhere in detail in this SAI. Each Fund’s Chief Compliance Officer oversees implementation of the Subsidiary’s policies and procedures, and makes periodic reports to the Trust’s Board of Trustees regarding the Subsidiary’s compliance with its policies and procedures. Each Fund and each Subsidiary test for compliance with certain investment restrictions on a consolidated basis, except that with respect to its investments in certain securities that may involve leverage, each Subsidiary complies with asset segregation requirements to the same extent as each Fund.
The Subsidiaries are not registered under the 1940 Act, and, unless otherwise noted in the Fund’s Prospectus or this SAI, are not subject to all the investor protections of the 1940 Act. However, each Fund wholly owns and controls a Subsidiary, and each Fund and each Subsidiary are managed by BFA, making it unlikely that a Subsidiary will take any actions contrary to the interests of a Fund and its shareholders. The Trust’s Board of Trustees has oversight responsibility for the investment activities of each Fund, including its investment in the Subsidiaries, and the Fund’s role as sole shareholder of the Subsidiaries. As noted above, the Subsidiaries will be subject to the same investment restrictions and limitations, and follow the same compliance policies and procedures, as each Fund. Changes in the laws of the United States and/or the Cayman Islands could result in the inability of each Fund and/or the Subsidiaries to operate as described in the Fund’s Prospectus and this Statement of Additional Information and could adversely affect each Fund. For example, the Cayman Islands does not currently impose any income, corporate or capital gains taxes, estate duty, inheritance tax, gift tax or withholding tax on the Subsidiaries. If Cayman Islands law changes such that the Subsidiaries must pay Cayman Islands taxes, Fund shareholders would likely suffer decreased investment returns.
Each Fund has requested a private letter ruling from the IRS confirming that the annual net profit, if any, realized by its Subsidiary and imputed for income tax purposes to the Fund will constitute “qualifying income” for purposes of the Fund remaining qualified as a regulated investment company for U.S. federal income tax purposes. The IRS has indicated that the granting of private letter rulings, like the one requested by each Fund, is currently suspended, pending further internal discussion. As a result, there can be no assurance that the IRS will grant the private letter ruling requested. If the IRS does not grant the private letter ruling request, there is a risk that the IRS could assert that the annual net profit realized by a Subsidiary and imputed for income tax purposes to a Fund will not be considered “qualifying income” for purposes of the Fund remaining qualified as a regulated investment company for U.S. federal income tax purposes. If a Fund fails to receive a

private letter ruling, it may elect not to form or invest through a Subsidiary. Such an occurrence may, in turn, reduce a Fund’s ability to gain investment exposure to commodities and track the performance of its Underlying Index. Moreover, changes in the laws of the United States and/or the Cayman Islands could result in the inability of each Fund and/or the Subsidiaries to operate as described in this prospectus and the SAI and could adversely affect each Fund. For example, the Cayman Islands does not currently impose any income, corporate or capital gains taxes, estate duty, inheritance tax, gift tax or withholding tax on the Subsidiaries. If Cayman Islands law changes such that the Subsidiaries must pay Cayman Islands taxes, Fund shareholders would likely experience decreased investment returns.

Diversification Status. The Funds are diversified. With respect to 75% of its total assets, a diversified fund does not invest more than 5% of its total assets in securities of any one issuer and does not acquire more than 10% of the outstanding voting securities of any one issuer (excluding cash and cash items, government securities, and securities of other investment companies). The remaining 25% of the fund’s total assets may be invested in any manner.

Each Fund intends to maintain the required level of diversification and otherwise conduct its operations so as to qualify as a Regulated Investment Company (“RIC”) for purposes of the Internal Revenue Code, and to relieve the Fund of any liability for U.S. federal income tax to the extent that its earnings are distributed to shareholders, provided that the Fund satisfies a minimum distribution requirement.

Investments in Underlying Funds and other Investment Companies. To implement its asset allocation strategy, each Fund invests its assets in a combination of Underlying Funds. Each Underlying Fund generally invests directly in portfolio securities. Each Fund may also invest in other investment companies, including ETFs that are not iShares ETFs, to the extent permitted by law.

Lending Portfolio Securities. Each Fund may lend portfolio securities to certain creditworthy borrowers, including borrowers affiliated with BFA. The borrowers provide collateral that is maintained in an amount at least equal to the current market value of the securities loaned. A Fund may terminate a loan at any time and obtain the return of the securities loaned. Each Fund receives the value of any interest or cash or non-cash distributions paid on the loaned securities.

With respect to loans that are collateralized by cash, the borrower will be entitled to receive a fee based on the amount of cash collateral. The Funds are compensated by the difference between the amount earned on the reinvestment of cash collateral and the fee paid to the borrower. In the case of collateral other than cash, a Fund is compensated by a fee paid by the borrower equal to a percentage of the market value of the loaned securities. Any cash collateral may be reinvested in certain short-term instruments either directly on behalf of each lending Fund or through one or more joint accounts or money market funds, including those affiliated with BFA; such reinvestments are subject to investment risk. BFA may receive compensation for these investments.

Securities lending involves exposure to certain risks, including operational risk (i.e., the risk of losses resulting from problems in the settlement and accounting process), “gap” risk (i.e., the risk of a mismatch between the return on cash collateral reinvestments and the fees each Fund has agreed to pay a borrower), and credit, legal, counterparty and market risk. If a securities lending counterparty were to default, a Fund would be subject to the risk of a possible delay in receiving collateral or in recovering the loaned securities, or to a possible loss of rights in the collateral. In the event a borrower does not return a Fund’s securities as agreed, the Fund may experience losses if the proceeds received from liquidating the collateral do not at least equal the value of the loaned security at the time the collateral is liquidated, plus the transaction costs incurred in purchasing replacement securities. This event could trigger adverse tax consequences for the Funds. Substitute payments for dividends received by a Fund for securities loaned out by the Fund will not be considered qualified dividend income. The Fund takes the tax effects of this difference into account in its securities lending program.

Each Fund pays a portion of the interest or fees earned from securities lending to a borrower as described above and to a securities lending agent who administers the lending program in accordance with guidelines approved by the Trust’s Board of Trustees (the “Board” or the “Trustees”). To the extent that the Funds engage in securities lending, BTC acts as securities lending agent for the Funds, subject to the overall supervision of BFA. BTC receives a portion of the revenues generated by securities lending activities as compensation for its services.

Short-Term Instruments and Temporary Investments. Each Fund may invest in short-term instruments, including money market instruments, on an ongoing basis to provide liquidity or for other reasons. Money market instruments are generally short-term investments that may include but are not limited to: (i) shares of money market funds (including those advised by BFA or otherwise affiliated with BFA); (ii) obligations issued or guaranteed by the U.S. government, its agencies or

instrumentalities (including government-sponsored enterprises); (iii) negotiable certificates of deposit (“CDs”), bankers’ acceptances, fixed-time deposits and other obligations of U.S. and non-U.S. banks (including non-U.S. branches) and similar institutions; (iv) commercial paper rated, at the date of purchase, “Prime-1” by Moody’s® Investors Service, Inc. (“Moody’s”), “F-1” by Fitch Inc. (“Fitch”), or “A-1” by Standard & Poor’s® (a subsidiary of The McGraw-Hill Companies, Inc.) (“S&P® ”), or if unrated, of comparable quality as determined by BFA; (v) non-convertible corporate debt securities (e.g., bonds and debentures) with remaining maturities at the date of purchase of not more than 397 days and that satisfy the rating requirements set forth in Rule 2a-7 under the 1940 Act; (vi) repurchase agreements; and (vii) short-term U.S. dollar-denominated obligations of non-U.S. banks (including U.S. branches) that, in the opinion of BFA, are of comparable quality to obligations of U.S. banks which may be purchased by a Fund. Any of these instruments may be purchased on a current or forward-settled basis. Time deposits are non-negotiable deposits maintained in banking institutions for specified periods of time at stated interest rates. Bankers’ acceptances are time drafts drawn on commercial banks by borrowers, usually in connection with international transactions. See Risks of the Underlying Funds below.

U.S. Government Obligations. The Funds may invest in various types of U.S. government obligations. U.S. government obligations are a type of bond and include securities issued or guaranteed as to principal and interest by the U.S. government, its agencies or instrumentalities. Payment of principal and interest on U.S. government obligations (i) may be backed by the full faith and credit of the United States or (ii) may be backed solely by the issuing or guaranteeing agency or instrumentality itself (as with Federal National Mortgage Association (“FNMA”), Federal Home Loan Mortgage Corporation (“FHLMC”) and Federal Home Loan Bank (“FHLB”) notes). In the latter case, each Fund must look principally to the agency or instrumentality issuing or guaranteeing the obligation for ultimate repayment, which agency or instrumentality may be privately owned. There can be no assurance that the U.S. government would provide financial support to its agencies or instrumentalities where it is not obligated to do so. As a general matter, the value of debt instruments, including U.S. government obligations, declines when market interest rates increase and rises when market interest rates decrease. Certain types of U.S. government obligations are subject to fluctuations in yield or value due to their structure or contract terms.

In 2008, FNMA and FHLMC were placed under the conservatorship of the U.S. Federal Housing Finance Agency (“FHFA”). Under this conservatorship, the FHFA operates and manages the agencies, and the U.S. Department of the Treasury has agreed to provide capital as needed (up to $100 billion per agency) to ensure that the agencies continue to provide liquidity to the housing and mortgage markets.

On August 5, 2011, S&P downgraded U.S. Treasury securities from a AAA rating to AA+. A downgrade of the ratings of U.S. government debt obligations, which are often used as a benchmark for other borrowing arrangements, could result in higher interest rates for individual and corporate borrowers, cause disruptions in the international bond markets and generally have a substantial negative effect on the U.S. economy. A downgrade of U.S. Treasury securities from another ratings agency or a further downgrade beyond AA+ rating by Standard & Poor’s may cause the value of a Fund’s U.S. Treasury obligations to decline.

Risks of the Underlying Funds

Set forth below is more detailed information regarding types of instruments in which the Underlying Funds, and in some cases the Funds, may invest, strategies BFA may employ in pursuit of an Underlying Fund’s investment objective, and related risks.

Asset-Backed and Commercial Mortgage-Backed Securities. Certain of the Underlying Funds may invest in asset-backed and commercial mortgage-backed securities. Asset-backed securities are securities backed by installment contracts, credit-card receivables or other assets. Commercial mortgage-backed securities are securities backed by commercial real estate properties. Both asset-backed and commercial mortgage-backed securities represent interests in “pools” of assets in which payments of both interest and principal on the securities are made on a regular basis. The payments are, in effect, “passed through” to the holder of the securities (net of any fees paid to the issuer or guarantor of the securities). The average life of asset-backed and commercial mortgage-backed securities varies with the maturities of the underlying instruments and, as a result of prepayments, can often be less than the original maturity of the assets underlying the securities. For this and other reasons, an asset-backed or commercial mortgage-backed security’s stated maturity may be shortened, and the security’s total return may be difficult to predict precisely. Also see Mortgage Pass-Through Securities and Mortgage Securities below.

Beginning in the second half of 2007 through 2009, the market for asset-backed and mortgage-backed securities

experienced substantially, often dramatically, lower valuations and reduced liquidity. These instruments continue to be subject to liquidity constraints, price volatility, credit downgrades and increases in default rates and, therefore, may be more difficult to value and more difficult to dispose of than previously.

Bonds. Certain of the Underlying Funds may invest in bonds. A bond is an interest-bearing security issued by a company, governmental unit or a non-U.S. entity. The issuer of a bond has a contractual obligation to pay interest at a stated rate on specific dates and to repay principal (the bond’s face value) periodically or on a specified maturity date. Bonds generally are used by corporations and governments to borrow money from investors.

An issuer may have the right to redeem or “call” a bond before maturity, in which case a fund may have to reinvest the proceeds at lower market rates. Similarly, a fund may have to reinvest interest income or payments received when bonds mature, sometimes at lower market rates. Most bonds bear interest income at a “coupon” rate that is fixed for the life of the bond. The value of a fixed-rate bond usually rises when market interest rates fall, and falls when market interest rates rise. Accordingly, a fixed-rate bond’s yield (income as a percent of the bond’s current value) may differ from its coupon rate as its value rises or falls. When an investor purchases a fixed-rate bond at a price that is greater than its face value, the investor is purchasing the bond at a premium. Conversely, when an investor purchases a fixed-rate bond at a price that is less than its face value, the investor is purchasing the bond at a discount. Fixed-rate bonds that are purchased at a discount pay less current income than securities with comparable yields that are purchased at face value, with the result that prices for such fixed-rate securities can be more volatile than prices for such securities that are purchased at face value. Other types of bonds bear interest at an interest rate that is adjusted periodically. Interest rates on “floating rate” or “variable rate” bonds may be higher or lower than current market rates for fixed-rate bonds of comparable quality with similar final maturities. Because of their adjustable interest rates, the value of “floating rate” or “variable rate” bonds fluctuates much less in response to market interest rate movements than the value of fixed-rate bonds, but the value may decline if their interest rates do not rise as much, or as quickly, as interest rates in general. Each Underlying Fund may treat some of these bonds as having a shorter maturity for purposes of calculating the weighted average maturity of its investment portfolio. Generally, prices of higher quality issues tend to fluctuate less with changes in market interest rates than prices of lower quality issues and prices of longer maturity issues tend to fluctuate more than prices of shorter maturity issues. Bonds may be senior or subordinated obligations. Senior obligations generally have the first claim on a corporation’s earnings and assets and, in the event of liquidation, are paid before subordinated obligations. Bonds may be unsecured (backed only by the issuer’s general creditworthiness) or secured (backed by specified collateral).

Corporate Bonds. Certain of the Underlying Funds may invest in investment-grade corporate bonds. The investment return of corporate bonds reflects interest earned on the security and changes in the market value of the security. The market value of a corporate bond may be affected by changes in the market rate of interest, the credit rating of the corporation, the corporation’s performance and perceptions of the corporation in the market place. There is a risk that the issuers of the securities may not be able to meet their obligations on interest or principal payments at the time called for by an instrument.

Currency Transactions. The Underlying Funds that may engage in currency transactions do not expect to engage in currency transactions for the purpose of hedging against declines in the value of the Underlying Funds’ assets that are denominated in a non-U.S. currency. An Underlying Fund may enter into non-U.S. currency forward and non-U.S. currency futures contracts to facilitate local securities settlements or to protect against currency exposure in connection with its distributions to shareholders, but may not enter into such contracts for speculative purposes.

A forward currency contract is an obligation to purchase or sell a specific currency at a future date, which may be any fixed number of days from the date of the contract agreed upon by the parties, at a price set at the time of the contract. A currency futures contract is a contract involving an obligation to deliver or acquire the specified amount of a specific currency, at a specified price and at a specified future time. Currency futures contracts may be settled on a net cash payment basis rather than by the sale and delivery of the underlying currency. To the extent required by law, liquid assets committed to futures contracts will be maintained.

Foreign exchange transactions involve a significant degree of risk and the markets in which foreign exchange transactions are effected are highly volatile, highly specialized and highly technical. Significant changes, including changes in liquidity and prices, can occur in such markets within very short periods of time, often within minutes. Foreign exchange trading risks include, but are not limited to, exchange rate risk, counterparty risk, maturity gap, interest rate risk, and potential interference by foreign governments through regulation of local exchange markets, foreign investment or particular transactions in non-U.S. currency. If BFA utilizes foreign exchange transactions at an inappropriate time or judges market conditions, trends or

correlations incorrectly, foreign exchange transactions may not serve their intended purpose of improving the correlation of an Underlying Fund’s return with the performance of its Underlying Index and may lower the Underlying Fund’s return. Each Underlying Fund could experience losses if the value of its currency forwards, options and futures positions were poorly correlated with its other investments or if it could not close out its positions because of an illiquid market. In addition, each Underlying Fund could incur transaction costs, including trading commissions, in connection with certain non-U.S. currency transactions.

Dividend Risk. There is no guarantee that the issuer of the stocks held by an Underlying Fund will declare dividends in the future or that if declared, they will either remain at current levels or increase over time.

Equity Securities. Equity securities generally have greater price volatility than fixed-income securities. The market price of equity securities may go up or down, sometimes rapidly or unpredictably. Equity securities may decline in value due to factors affecting equity securities markets generally; particular industries, sectors or geographic regions represented in those markets; or individual issuers. The types of developments that may affect an issuer of an equity security include management performance, financial leverage and reduced demand for the issuer’s goods or services. Common and preferred stock represent equity or ownership interests in an issuer. Preferred stock, however, pays dividends at a specified rate and has precedence over common stock in the payment of dividends. In the event an issuer is liquidated or declares bankruptcy, the claims of owners of bonds and preferred stock take precedence over the claims of those who own common stock.

Futures and Options. Futures contracts and options may be used by a Fund or an Underlying Fund to simulate investment in its Underlying Index, to facilitate trading or to reduce transaction costs. Each Underlying Fund may enter into futures contracts and options that are traded on a U.S. or non-U.S. exchange. No Underlying Fund will use futures or options for speculative purposes. Each Fund and Underlying Fund intends to use futures and options in accordance with Rule 4.5 of the Commodity Exchange Act (“CEA”). The Trust, on behalf of each Fund and Underlying Fund, has claimed an exclusion from the definition of the term “commodity pool operator” in accordance with Rule 4.5 so that each Underlying Fund is not subject to registration or regulation as a commodity pool operator under the CEA. On February 11, 2011, however, the Commodity Futures Trading Commission (“CFTC”) proposed certain regulatory changes that would subject registered investment companies to regulation by the CFTC if a fund invests more than a prescribed level of its liquidation value in futures and certain other instruments, or if the fund markets itself as providing investment exposure to such instruments. If these regulatory changes are ultimately adopted by the CFTC, each Underlying Fund may be subject to the CFTC registration requirements, and the disclosure and operations of each Fund would need to comply with all applicable regulations governing commodity pools. Compliance with these additional registration and regulatory requirements would increase Fund expenses. BFA may also be subject to CFTC regulation if each Underlying Fund is deemed to be a commodity pool. Other potentially adverse regulatory initiatives could also develop.

Futures contracts provide for the future sale by one party and purchase by another party of a specified amount of a specific instrument or index at a specified future time and at a specified price. Stock index contracts are based on investments that reflect the market value of common stock of the firms included in the investments. Each Underlying Fund may enter into futures contracts to purchase securities indexes when BFA anticipates purchasing the underlying securities and believes prices will rise before the purchase will be made. To the extent required by law, liquid assets committed to futures contracts will be maintained.

A call option gives a holder the right to purchase a specific security at a specified price (“exercise price”) within a specified period of time. A put option gives a holder the right to sell a specific security at a specified exercise price within a specified period of time. The initial purchaser of a call option pays the “writer” a premium, which is paid at the time of purchase and is retained by the writer whether or not such option is exercised. Each Underlying Fund may purchase put options to hedge its portfolio against the risk of a decline in the market value of securities held and may purchase call options to hedge against an increase in the price of securities it is committed to purchase. Each Underlying Fund may write put and call options along with a long position in options to increase its ability to hedge against a change in the market value of the securities it holds or is committed to purchase. Investments in futures contracts and other investments that contain leverage may require each Underlying Fund to maintain liquid assets. Generally, each Underlying Fund maintains an amount of liquid assets equal to its obligations relative to the position involved, adjusted daily on a marked-to-market basis. With respect to futures contracts that are contractually required to “cash-settle,” each Underlying Fund maintains liquid assets in an amount at least equal to each Underlying Fund’s daily marked-to-market obligation (i.e., each Underlying Fund’s daily net liability, if any), rather than the contracts’ notional value (i.e., the value of the underlying asset). By maintaining assets equal to its net obligation under cash-settled futures contracts, the Underlying Fund may employ leverage to a greater extent than if each Underlying Fund set

aside assets equal to the futures contracts’ full notional value. Each Underlying Fund bases its asset maintenance policies on methods permitted by the staff of the SEC and may modify these policies in the future to comply with any changes in the guidance articulated from time to time by the SEC or its staff.

Illiquid Securities. Certain of the Underlying Funds may invest up to 15% of the value of their respective net assets in securities as to which a liquid trading market does not exist, provided such investments are consistent with their respective investment objectives. Such securities may include securities that are not readily marketable, such as privately issued securities and other securities that are subject to legal or contractual restrictions on resale, fixed time deposits that are subject to withdrawal penalties as to which an Underlying Fund cannot exercise a demand feature on less than seven days’ notice and as to which there is no secondary market, and repurchase agreements providing for settlement more than seven days after notice.

Inflation-Protected Obligations. Certain of the Underlying Funds invest almost exclusively in inflation-protected public obligations of the U.S. Treasury, commonly known as “TIPS.” TIPS are a type of U.S. government obligation issued by the U.S. Treasury that are designed to provide inflation protection to investors. TIPS are income-generating instruments whose interest and principal payments are adjusted for inflation — a sustained increase in prices that erodes the purchasing power of money. The inflation adjustment, which is typically applied monthly to the principal of the bond, follows a designated inflation index, such as the consumer price index. A fixed-coupon rate is applied to the inflation-adjusted principal so that as inflation rises, both the principal value and the interest payments increase. This can provide investors with a hedge against inflation, as it helps preserve the purchasing power of an investment. Because of this inflation adjustment feature, inflation-protected bonds typically have lower yields than conventional fixed-rate bonds.

Investment Companies. Each Underlying Fund may invest in the securities of other investment companies (including money market funds) to the extent allowed by law. Under the 1940 Act, an Underlying Fund’s investment in investment companies is limited to, subject to certain exceptions, (i) 3% of the total outstanding voting stock of any one investment company, (ii) 5% of the Underlying Fund’s total assets with respect to any one investment company, and (iii) 10% of the Underlying Fund’s total assets with respect to investment companies in the aggregate. To the extent allowed by law or regulation, each Underlying Fund may invest its assets in securities of investment companies that are money market funds, including those advised by BFA or otherwise affiliated with BFA, in excess of the limits discussed above. Other investment companies in which an Underlying Fund invests can be expected to incur fees and expenses for operations, such as investment advisory and administration fees, that would be in addition to those incurred by the Underlying Fund.

An Underlying Fund may purchase shares of ETFs. An Underlying Fund may purchase ETF shares for the same reason it would purchase (and as an alternative to purchasing) futures contracts – to obtain relatively low-cost exposure to the stock market while maintaining flexibility to meet the liquidity needs of the Underlying Fund. ETF shares enjoy several advantages over futures. Depending on the market, the holding period, and other factors, ETF shares can be less costly than futures. In addition, ETF shares can be purchased for smaller sums and offer exposure to market sectors and styles for which there is no suitable or liquid futures contract. An Underlying Fund may also purchase ETF shares for other purposes, including improving its ability to track its underlying index. An Underlying Fund may invest in shares of ETFs that are advised by BFA.

Investments in Underlying Funds. Each Underlying Fund is a type of investment company referred to as an ETF. Each Underlying Fund is designed to track a particular index and is advised by BFA. Shares of the Underlying Funds are listed for trading on the national securities exchanges and trade throughout the day on those exchanges and other secondary markets. There can be no assurance that the requirements of the national securities exchanges necessary to maintain the listing of shares of the Underlying Funds will continue to be met. A national securities exchange may, but is not required to, remove the shares of the Underlying Funds from listing if (i) following the initial 12-month period beginning upon the commencement of trading of an Underlying Fund, there are fewer than 50 beneficial holders of the shares for 30 or more consecutive trading days, (ii) the value of the Underlying Fund’s underlying index is no longer calculated or available, or (iii) any other event shall occur or condition exist that, in the opinion of the national securities exchange, makes further dealings on the national securities exchange inadvisable. A national securities exchange will remove the shares of an Underlying Fund from listing and trading upon termination of the Underlying Fund. Shares of each Underlying Fund trade on exchanges at prices at, above or below their most recent NAV. The per share NAV of each Underlying Fund is calculated at the end of each business day and fluctuates with changes in the market value of such Underlying Fund’s holdings since the most recent calculation. The trading prices of an Underlying Fund’s shares fluctuate continuously throughout trading hours based on market supply and demand rather than NAV. The trading prices of an Underlying Fund’s shares may deviate significantly from NAV during periods of market volatility. Any of these factors may lead to an Underlying Fund’s shares trading at a

premium or discount to NAV. Exchange prices are not expected to correlate exactly with an Underlying Fund’s NAV due to timing reasons as well as market supply and demand factors. In addition, disruptions to an Underlying Fund’s creations and redemptions or the existence of extreme market volatility may result in trading prices of Underlying Fund shares that differ significantly from NAV. If the Funds purchase shares of Underlying Funds at a time when the market price of an Underlying Fund’s shares are at a premium to the NAV or sells at a time when the market price of an Underlying Fund is at a discount to the NAV, then the Funds may sustain losses.


As in the case of other publicly-traded securities, brokers’ commissions on buying or selling shares of Underlying Funds will be based on negotiated commission rates at customary levels. An investment in an ETF generally presents the same primary risks as an investment in an open-end investment company that is not exchange-traded and that has the same investment objectives, strategies, and policies. However, ETFs are subject to the following risks that do not apply to an open-end investment company that is not exchange-traded: (i) the market price of the ETF’s shares may trade at a discount to their net asset value; (ii) an active trading market for an ETF’s shares may not develop or be maintained; or (iii) trading of an ETF’s shares may be halted if the listing exchange’s officials deem such action appropriate, the shares are delisted from the exchange, or the activation of market-wide “circuit breakers” (which are tied to large decreases in stock prices) halts stock trading generally.

Loans of Portfolio Securities. Each Underlying Fund may lend portfolio securities in the same manner as the Funds, as described above.

Mortgage Pass-Through Securities. Certain of the Underlying Funds may invest in mortgage pass-through securities which are a category of pass-through securities backed by pools of mortgages and issued by the Government Mortgage Association or Ginnie Mae, or by one of several U.S. government-sponsored enterprises, such as the FNMA, FHLMC, or FHLBs. In the basic mortgage pass-through structure, mortgages with similar issuer, term and coupon characteristics are collected and aggregated into a “pool” consisting of multiple mortgage loans. The pool is assigned a CUSIP number and undivided interests in the pool are traded and sold as pass-through securities. The holder of the security is entitled to a pro rata share of principal and interest payments (including unscheduled prepayments) from the pool of mortgage loans.


Mortgage securities issued by non-government entities may be subject to greater credit risk than those issued by government entities. The performance of privately-issued mortgage securities may depend on the integrity and competence of the institutions that originate the underlying mortgages, yet investors in these mortgage securities may have only limited access to information required to evaluate the practices of these mortgage originators. In order to prevent defaults by troubled mortgage borrowers, the sponsors of mortgage securities may have to renegotiate and investors in mortgage securities may have to accept less favorable interest rates or other terms on the mortgages underlying these securities. Unanticipated mortgage defaults or renegotiations of mortgage terms are likely to depress the prices of related mortgage securities. Although mortgage securities may be supported by some form of government or private guarantee and/or insurance, there is no assurance that private guarantors or insurers will meet their obligations. Guarantees, insurance and other forms of credit enhancement supporting mortgage securities may also be insufficient to cover all losses on underlying mortgages if mortgage borrowers default at a greater than expected rate.


An investment in a specific pool of pass-through securities requires an analysis of the specific prepayment risk of mortgages within the covered pool (since mortgagors typically have the option to prepay their loans). The level of prepayments on a pool of mortgage securities is difficult to predict and can impact the subsequent cash flows and value of the mortgage pool. In addition, when trading specific mortgage pools, precise execution, delivery and settlement arrangements must be negotiated for each transaction. These factors combine to make trading in mortgage pools somewhat cumbersome. For these and other reasons, an Underlying Fund may obtain exposure to U.S. agency mortgage pass-through securities primarily through the use of “to-be-announced” or “TBA transactions.” “TBA” refers to a commonly used mechanism for the forward settlement of U.S. agency mortgage pass-through securities, and not to a separate type of mortgage-backed security. Most transactions in mortgage pass-through securities occur through the use of TBA transactions. TBA transactions generally are conducted in accordance with widely-accepted guidelines that establish commonly observed terms and conditions for execution, settlement and delivery. In a TBA transaction, the buyer and seller decide on general trade parameters, such as agency, settlement date, par amount, and price. The actual pools delivered generally are determined two days prior to the settlement date. An Underlying Fund may use TBA transactions in several ways. For example, an Underlying Fund may regularly enter into TBA agreements and “roll over” such agreements prior to the settlement date stipulated in such agreements. This type of TBA transaction is sometimes known as a “TBA roll.” In a “TBA roll,” an Underlying Fund generally will sell the obligation to purchase the pools stipulated in the TBA agreement prior to the stipulated settlement date and will

enter into a new TBA agreement for future delivery of pools of mortgage pass-through securities. In addition, an Underlying Fund may enter into TBA agreements and settle such transactions on the stipulated settlement date by accepting actual receipt or delivery of the pools of mortgage pass-through securities stipulated in the TBA agreement. Default by or bankruptcy of a counterparty to a TBA transaction would expose an Underlying Fund to possible loss because of adverse market action, expenses or delays in connection with the purchase or sale of the pools of mortgage pass-through securities specified in the TBA transaction. To minimize this risk, an Underlying Fund will enter into TBA transactions only with established counterparties (such as major broker-dealers) and BFA will monitor the creditworthiness of such counterparties. The use of “TBA rolls” may cause an Underlying Fund to experience higher portfolio turnover and to pay higher capital gain distributions, which may result in larger amounts of short-term capital gains allocable to interestholders. The Underlying Funds maintain liquid assets in connection with TBA transactions.


Mortgage Securities. Certain of the Underlying Funds may invest in mortgage securities. Mortgage securities are issued by government and non-government entities such as banks, mortgage lenders, or other institutions. A mortgage security is an obligation of the issuer that is backed by a mortgage or pool of mortgages or a direct interest in an underlying pool of mortgages. Some mortgage securities, such as collateralized mortgage obligations, make payments of both principal and interest at a range of specified intervals; others make semi-annual interest payments at a pre-determined rate and repay principal at maturity (like a typical bond). Mortgage securities are based on different types of mortgages, including those on commercial real estate or residential properties. Stripped mortgage securities are created when the interest and principal components of a mortgage security are separated and sold as individual securities. In the case of a stripped mortgage security, the holder of the “principal-only” security (PO) receives the principal payments made by the underlying mortgage, while the holder of the “interest-only” security (IO) receives interest payments from the same underlying mortgage.


The value of mortgage securities may change due to shifts in the market’s perception of the creditworthiness of issuers and changes in interest rates or liquidity. The value of some mortgage-backed securities may be particularly sensitive to changes in prevailing interest rates. In addition, regulatory or tax changes may adversely affect the mortgage securities market as a whole. Mortgage securities issued by non-government entities may be subject to greater credit risk than those issued by government entities. The performance of privately-issued mortgage securities may depend on the integrity and competence of the institutions that originate the underlying mortgages, yet investors in these mortgage securities may have only limited access to information required to evaluate the practices of these mortgage originators. In order to prevent defaults by troubled mortgage borrowers, the sponsors of mortgage securities may have to renegotiate and investors in mortgage securities may have to accept less favorable interest rates or other terms on the mortgages underlying these securities. Unanticipated mortgage defaults or renegotiations of mortgage terms are likely to depress the prices of related mortgage securities. Although mortgage securities may be supported by some form of government or private guarantee and/or insurance, there is no assurance that private guarantors or insurers will meet their obligations. Guarantees, insurance and other forms of credit enhancement supporting mortgage securities may also be insufficient to cover all losses on underlying mortgages if mortgage borrowers default at a greater than expected rate.


Non-government mortgage securities may be subject to greater price changes than government issues. Mortgage securities are subject to prepayment risk. Prepayment risk is the risk that early principal payments made on the underlying mortgages, usually in response to a reduction in interest rates, will result in the return of principal to the investor, causing the investor to be invested subsequently at a lower current interest rate. Alternatively, in a rising interest rate environment, mortgage security values may be adversely affected when prepayments on underlying mortgages do not occur as anticipated, resulting in the extension of the security’s effective maturity and the related increase in interest rate sensitivity of a longer-term instrument. The prices of stripped mortgage securities tend to be more volatile in response to changes in interest rates than those of non-stripped mortgage securities. In addition, although mortgages and mortgage-related securities are generally supported by some form of government or private guarantee and/or insurance, there is no assurance that private guarantors or insurers will meet their obligations.

Mid-Capitalization Companies Risk. Many of the companies in which the Underlying Funds invest are considered mid-capitalization companies. Stock prices of mid-capitalization companies may be more volatile than those of large-capitalization companies and, therefore, a Fund’s share price may be more volatile than those of funds that invest a larger percentage of their assets in stocks issued by large-capitalization companies. Stock prices of mid-capitalization companies are also more vulnerable than those of large-capitalization companies to adverse business or economic developments, and the stocks of mid-capitalization companies may be less liquid, making it more difficult for the Underlying Funds to buy and sell them. In addition, mid-capitalization companies generally have less diverse product lines than large-capitalization companies and are more susceptible to adverse developments related to their products.

Non-Diversification Risk. Certain of the Underlying Funds may be classified as “non-diversified.” This means that the Underlying Fund may invest a large percentage of its assets in securities issued by or representing a small number of issuers. As a result, the Underlying Fund may be more susceptible to the risks associated with these particular issuers, or to a single economic, political or regulatory occurrence affecting these issuers.

Non-U.S. Securities and Emerging Markets Securities. The Funds and certain of the Underlying Funds may invest in securities of non-U.S. issuers. Investing in the securities of non-U.S. issuers involves special risks and considerations not typically associated with investing in U.S. issuers. These include differences in accounting, auditing and financial reporting standards, the possibility of expropriation or potentially confiscatory taxation or war, adverse changes in investment or exchange control regulations, political instability which could affect U.S. investments in non-U.S. countries, potential restrictions of the flow of international capital, generally less liquid and less efficient securities markets, generally greater price volatility, less publicly available information about issuers, the imposition of withholding or other taxes, higher transaction and custody costs, delays and risks attendant in settlement procedures, difficulties in enforcing contractual obligations, lesser liquidity and significantly smaller market capitalization of most non-U.S. securities markets, more substantial government interference with the economy and transaction costs of foreign currency conversions. Non-U.S. issuers may be subject to less governmental regulation than U.S. issuers. Moreover, individual foreign economies may differ favorably or unfavorably from the U.S. economy with respect to growth of gross domestic product, rate of inflation, capital reinvestment, resource self-sufficiency and balance of payment positions. In addition, changes in foreign exchange rates also will affect the value of securities denominated or quoted in currencies other than the U.S. dollar. Certain foreign markets have specific geographical risks such as a heightened likelihood of earthquakes, tsunamis, or volcanoes. Certain foreign markets also experience acts of terrorism, territorial disputes or other defense concerns. These situations may have a significant impact on the economies of, and investments in, these geographic areas.


The Funds and certain of the Underlying Funds may purchase publicly-traded common stocks of non-U.S. issuers. To the extent an Underlying Fund invests in securities of non-U.S. issuers, the Underlying Fund’s investment in such securities may also be in the form of American Depositary Receipts (“ADRs”), Global Depositary Receipts (“GDRs”) and European Depositary Receipts (“EDRs”) (collectively, “Depositary Receipts”). Depositary Receipts are receipts, typically issued by a bank or trust company, that evidence ownership of underlying securities issued by a non-U.S. issuer. For ADRs, the depositary is typically a U.S. financial institution and the underlying securities are issued by a non-U.S. issuer. For other forms of Depositary Receipts, the depositary may be a foreign or a U.S. entity, and the underlying securities may have a foreign or a U.S. issuer. Depositary Receipts are not necessarily denominated in the same currency as their underlying securities. Generally, ADRs, in registered form, are designed for use in the U.S. securities markets, and EDRs, in bearer form, are designed for use in European securities markets. GDRs are tradable both in the United States and in Europe and are designed for use throughout the world. An Underlying Fund may invest in Depositary Receipts through “sponsored” or “unsponsored” facilities. A sponsored facility is established jointly by the issuer of the underlying security and a depositary, whereas a depositary may establish an unsponsored facility without participation by the issuer of the deposited security. Holders of unsponsored Depositary Receipts generally bear all the costs of such facilities and the depositary of an unsponsored facility frequently is under no obligation to distribute interestholder communications received from the issuer of the deposited security or to pass through voting rights to the holders of such receipts in respect of the deposited securities. The issuers of unsponsored Depositary Receipts are not obligated to disclose material information in the United States and, therefore, there may be less information available regarding such issuers and there may not be a correlation between such information and the market value of the Depositary Receipts.


Obligations of Foreign Governments, Supranational Entities and Banks. The Funds and certain of the Underlying Funds may invest in U.S. dollar-denominated short-term obligations issued or guaranteed by one or more foreign governments or any of their political subdivisions, agencies or instrumentalities that are determined by BFA to be of comparable quality to the other obligations in which the Underlying Funds may invest. Certain foreign governments, specifically foreign governments in emerging markets, historically have encountered difficulties in servicing their debt obligations, withheld payments of principal and interest, and declared moratoria on the payment of principal and interest on their sovereign debts. The Funds and certain of the Underlying Funds may also invest in debt obligations of supranational entities. Supranational entities include international organizations designated or supported by governmental entities to promote economic reconstruction or development and international banking institutions and related government agencies. Examples include the International Bank for Reconstruction and Development (the World Bank), the Asian Development Bank and the InterAmerican Development Bank. The percentage of an Underlying Fund’s assets invested in obligations of foreign governments and supranational entities will vary depending on the relative yields of such securities, the economic and financial markets of the countries in which the investments are made and the interest rate climate of such countries. The Funds and certain of the

Underlying Funds may invest a portion of their total assets in high-quality, short-term (one year or less) debt obligations of foreign branches of U.S. banks or U.S. branches of foreign banks that are denominated in and pay interest in U.S. dollars.

Emerging Markets. Some non-U.S. markets in which certain of the Underlying Funds invest are considered to be emerging markets. Investment in these emerging markets subjects an Underlying Fund to a greater risk of loss than investments in developed markets. This is due to, among other things, greater market volatility, lower trading volume, political and economic instability, greater risk of market shut down and more governmental limitations on foreign investment policy than those typically found in developed markets.

Options on Futures Contracts. An option on a futures contract, as contrasted with the direct investment in such a contract, gives the purchaser the right, in return for the premium paid, to assume a position in the underlying futures contract at a specified exercise price at any time prior to the expiration date of the option. Upon exercise of an option, the delivery of the futures position by the writer of the option to the holder of the option will be accompanied by delivery of the accumulated balance in the writer’s futures margin account that represents the amount by which the market price of the futures contract exceeds (in the case of a call) or is less than (in the case of a put) the exercise price of the option on the futures contract. The potential for loss related to the purchase of an option on a futures contract is limited to the premium paid for the option plus transaction costs. Because the value of the option is fixed at the point of sale, there are no daily cash payments by the purchaser to reflect changes in the value of the underlying contract; however, the value of the option changes daily and that change would be reflected in the NAV of each Fund. The potential for loss related to writing call options is unlimited. The potential for loss related to writing put options is limited to the agreed upon price per share, also known as the “strike price,” less the premium received from writing the put.

Each Underlying Fund may purchase and write put and call options on futures contracts that are traded on an exchange as a hedge against changes in value of its portfolio securities, or in anticipation of the purchase of securities, and may enter into closing transactions with respect to such options to terminate existing positions. There is no guarantee that such closing transactions can be effected.

Upon entering into a futures contract, an Underlying Fund will be required to deposit with the broker an amount of cash or cash equivalents known as “initial margin,” which is in the nature of a performance bond or good faith deposit on the contract and is returned to each Underlying Fund upon termination of the futures contract, assuming all contractual obligations have been satisfied. Subsequent payments, known as “variation margin,” to and from the broker will be made daily as the price of the index underlying the futures contract fluctuates, making the long and short positions in the futures contract more or less valuable, a process known as “marking-to-market.” At any time prior to the expiration of a futures contract, each Underlying Fund may elect to close the position by taking an opposite position, which will operate to terminate an Underlying Fund’s existing position in the contract.

Ratings. An investment-grade rating means the security or issuer is rated investment-grade by Moody’s® , S&P® , Fitch, Dominion Bond Rating Service Limited (“Dominion”), or another credit rating agency designated as a nationally recognized statistical rating organization (“NRSRO”) by the SEC, or is unrated but considered to be of equivalent quality by BFA. Bonds rated Baa or above by Moody’s, BBBL by Dominion or BBB or above by S&P and Fitch are considered “investment-grade” securities, bonds rated Baa are considered medium grade obligations subject to moderate credit risk and may possess certain speculative characteristics, while bonds rated BBB are regarded as having adequate capacity to meet financial commitments.

Subsequent to purchase by the applicable Underlying Fund, a rated security may cease to be rated or its rating may be reduced below an investment-grade rating. Bonds rated lower than Baa3 by Moody’s, BBB- by S&P or BB by Fitch are considered below investment-grade quality and are obligations of issuers that are considered predominantly speculative with respect to the issuer’s capacity to pay interest and repay principal according to the terms of the obligation and, therefore, carry greater investment risk, including the possibility of issuer default and bankruptcy and increased market price volatility. Such securities (“lower-rated securities”) are commonly referred to as “junk bonds” and are subject to a substantial degree of credit risk. Lower-rated securities are often issued by smaller, less creditworthy companies or by highly leveraged (indebted) firms, which are generally less able than more financially stable firms to make scheduled payments of interest and principal. The risks posed by securities issued under such circumstances are substantial. Bonds rated below investment-grade tend to be less marketable than higher-quality bonds because the market for them is less broad. The market for unrated bonds is even narrower. Please see Appendix A of this SAI for a description of each rating category of Moody’s, S&P, Fitch and Dominion.

Real Estate Company Risk. An Underlying Fund that invests in companies that invest in real estate, such as a real estate investment trust (“REIT”) or real estate holding companies (collectively, “Real Estate Companies”) is exposed to unique risks that relate specifically to the way in which Real Estate Companies are organized and operated. Real estate is a cyclical business, highly sensitive to general and local economic conditions and developments, and characterized by intense competition and periodic overbuilding.

Interest Rate Risk. Rising interest rates could result in higher costs of capital for Real Estate Companies, which could negatively impact a Real Estate Company’s ability to meet its payment obligations.

Leverage Risk. Real Estate Companies may use leverage (and some may be highly leveraged), which increases investment risk and could adversely affect a Real Estate Company’s operations and market value in periods of rising interest rates as well as risks normally associated with debt financing. Financial covenants related to a Real Estate Company’s leverage may affect the ability of the Real Estate Company to operate effectively. In addition, real property may be subject to the quality of credit extended and defaults by borrowers and tenants. If the properties do not generate sufficient income to meet operating expenses, including, where applicable, debt service, ground lease payments, tenant improvements, third-party leasing commissions and other capital expenditures, the income and ability of a Real Estate Company to make payments of any interest and principal on its debt securities will be adversely affected.

Property Risk. Real Estate Companies may be subject to risks relating to functional obsolescence or reduced desirability of properties; extended vacancies due to economic conditions and tenant bankruptcies; catastrophic events such as earthquakes, hurricanes and terrorist acts; and casualty or condemnation losses. Real estate income and values also may be greatly affected by demographic trends, such as population shifts or changing tastes and values, or increasing vacancies or declining rents resulting from legal, cultural, technological, global or local economic developments.

Management Risk. Real Estate Companies are dependent upon management skills and may have limited financial resources. Real Estate Companies are generally not diversified and may be subject to heavy cash flow dependency, default by borrowers and self-liquidation. In addition, transactions between Real Estate Companies and their affiliates may be subject to conflicts of interest, which may adversely affect a Real Estate Company’s shareholders. A Real Estate Company may also have joint venture investments in certain of its properties and, consequently, its ability to control decisions relating to such properties may be limited.

Liquidity Risk. Investing in Real Estate Companies may involve risks similar to those associated with investing in small-capitalization companies. Real Estate Company securities, like the securities of other smaller companies, may be more volatile than, and perform differently from, shares of large capitalization companies. There may be less trading in Real Estate Company shares, which means that buy and sell transactions in those shares could have a magnified impact on share price, resulting in abrupt or erratic price fluctuations. In addition, real estate is relatively illiquid and, therefore, a Real Estate Company may have a limited ability to vary or liquidate properties in response to changes in economic or other conditions.

Concentration Risk. Real Estate Companies may lack diversification, due to ownership of a limited number of properties and concentration in a particular geographic region or property type.

U.S. Tax Risk. Certain U.S. Real Estate Companies are subject to special U.S. federal tax requirements. A REIT that fails to comply with such tax requirements may be subject to U.S. federal income taxation, which may affect the value of the REIT and the characterization of the REIT’s distributions. The U.S. federal tax requirement that a REIT distribute substantially all of its net income to its shareholders may result in a REIT having insufficient capital for future expenditures.

Regulatory Risk. Real estate income and values may be adversely affected by such factors as applicable domestic and foreign laws (including tax laws). Government actions, such as tax increases, zoning law changes or environmental regulations, also may have a major impact on real estate.

Repurchase Agreements. A repurchase agreement is an instrument under which the purchaser (i.e., an Underlying Fund) acquires the security and the seller agrees, at the time of the sale, to repurchase the security at a mutually agreed upon time and price, thereby determining the yield during the purchaser’s holding period. Repurchase agreements may be construed to be collateralized loans by the purchaser to the seller secured by the securities transferred to the purchaser. If a repurchase

agreement is construed to be a collateralized loan, the underlying securities will not be considered to be owned by each Underlying Fund but only to constitute collateral for the seller’s obligation to pay the repurchase price, and, in the event of a default by the seller, each Underlying Fund may suffer time delays and incur costs or losses in connection with the disposition of the collateral.

In any repurchase transaction, the collateral for a repurchase agreement may include: (i) cash items; (ii) obligations issued by the U.S. government or its agencies or instrumentalities; or (iii) obligations that, at the time the repurchase agreement is entered into, are rated in the highest rating category generally by at least two NRSROs, or, if unrated, determined to be of comparable quality by BFA. Collateral, however, is not limited to the foregoing and may include, for example, obligations rated below the highest category by NRSROs. Collateral for a repurchase agreement may also include securities that an Underlying Fund could not hold directly without the repurchase obligation. Irrespective of the type of collateral underlying the repurchase agreement, in the case of a repurchase agreement entered into by a non-money market fund, the repurchase obligation of a seller must be of comparable credit quality to securities which are rated in one of the two highest rating categories by any NRSRO.

Repurchase agreements pose certain risks for an Underlying Fund that utilizes them. Such risks are not unique to the Underlying Funds, but are inherent in repurchase agreements. The Underlying Funds seek to minimize such risks, but because of the inherent legal uncertainties involved in repurchase agreements, such risks cannot be eliminated. Lower quality collateral and collateral with longer maturities may be subject to greater price fluctuations than higher quality collateral and collateral with shorter maturities. If the repurchase agreement counterparty were to default, lower quality collateral may be more difficult to liquidate than higher quality collateral. Should the counterparty default and the amount of collateral not be sufficient to cover the counterparty’s repurchase obligation, the Underlying Fund would retain the status of an unsecured creditor of the counterparty (i.e., the position the Underlying Fund would normally be in if it were to hold, pursuant to its investment policies, other unsecured debt securities of the defaulting counterparty) with respect to the amount of the shortfall. As an unsecured creditor, an Underlying Fund would be at risk of losing some or all of the principal and income involved in the transaction.

Reverse Repurchase Agreements. Reverse repurchase agreements involve the sale of securities with an agreement to repurchase the securities at an agreed-upon price, date and interest payment and have the characteristics of borrowing. Generally, the effect of such transactions is that each Underlying Fund can recover all or most of the cash invested in the portfolio securities involved during the term of the reverse repurchase agreement, while in many cases the Fund is able to keep some of the interest income associated with those securities. Such transactions are advantageous only if each Underlying Fund has an opportunity to earn a rate of interest on the cash derived from these transactions that is greater than the interest cost of obtaining the same amount of cash. Opportunities to realize earnings from the use of the proceeds equal to or greater than the interest required to be paid may not always be available and each Underlying Fund intends to use the reverse repurchase technique only when BFA believes it will be advantageous to the Underlying Fund. The use of reverse repurchase agreements may exaggerate any interim increase or decrease in the value of each Underlying Fund’s assets. An Underlying Fund’s exposure to reverse repurchase agreements will be covered by liquid assets having a value equal to or greater than such commitments.

Risks of Derivatives. A derivative is a financial contract, the value of which depends on, or is derived from, the value of an underlying asset such as a security or an index. Each Underlying Fund may invest in variable rate demand notes and obligations, and tender option bonds, which may be considered derivatives. Compared to conventional securities, derivatives can be more sensitive to changes in interest rates or to sudden fluctuations in market prices and thus a Fund’s losses may be greater if it invests in derivatives than if it invests only in conventional securities. Derivatives are also subject to counterparty risk, which is the risk that the other party in the transaction will not fulfill its contractual obligations.

Risks of Investing in Asia. Investments in securities of issuers in certain Asian countries involve risks not typically associated with investments in securities of issuers in more developed countries. Such heightened risks include, among others, expropriation and/or nationalization of assets, confiscatory taxation, political instability, including authoritarian and/or military involvement in governmental decision-making, armed conflict and social instability as a result of religious, ethnic and/or socio-economic unrest.

Certain Asian countries have democracies with relatively short histories, which may increase the risk of political instability. These countries have faced political and military unrest, and further unrest could present a risk to their local economies and securities markets. Indonesia and the Philippines have each experienced violence and terrorism, which has negatively

impacted their economies. North and South Korea each have substantial military capabilities, and historical tensions between the two countries present the risk of war. Any outbreak of hostilities between the two countries could have a severe adverse effect on the South Korean economy and securities market. Increased political and social unrest in these geographic areas could adversely affect the performance of investments in this region.

Certain governments in this region administer prices on several basic goods, including fuel and electricity, within their respective countries. Certain governments may exercise substantial influence over many aspects of the private sector in their respective countries and may own or control many companies. Future government actions could have a significant effect on the economic conditions in this region, which in turn could have a negative impact on private sector companies. There is also the possibility of diplomatic developments adversely affecting investments in the region.

Corruption and the perceived lack of a rule of law in dealings with international companies in certain Asian countries may discourage foreign investment and could negatively impact the long-term growth of certain economies in this region. In addition, certain countries in the region are experiencing high unemployment and corruption, and have fragile banking sectors.

Some economies in this region are dependent on a range of commodities, including oil, natural gas and coal. Accordingly, they are strongly affected by international commodity prices and particularly vulnerable to any weakening in global demand for these products. The market for securities in this region may also be directly influenced by the flow of international capital, and by the economic and market conditions of neighboring countries. Adverse economic conditions or developments in neighboring countries may increase investors’ perception of the risk of investing in the region as a whole, which may adversely impact the market value of the securities issued by companies in the region.

Risks of Investing in Australasia. The economies of Australasia, which include Australia and New Zealand, are dependent on exports from the agricultural and mining sectors. This makes Australasian economies susceptible to fluctuations in the commodity markets. Australasian economies are also increasingly dependent on their growing service industries. Because the economies of Australasia are dependent on the economies of Asia, Europe and the United States as key trading partners and investors, reduction in spending by any of these trading partners on Australasian products and services, or negative changes in any of these economies, may cause an adverse impact on some or all of the Australasian economies. Additionally, Australia and New Zealand are located in a region that has historically been prone to natural disasters. Any natural disaster in the region could negatively impact the economies of Australia and New Zealand and affect the value of securities held by a Fund.

Risks of Investing in Europe. The Economic and Monetary Union of the European Union (the “EU”) requires member countries to comply with restrictions on inflation rates, deficits, interest rates, debt levels and fiscal and monetary controls, each of which may significantly affect every country in Europe. Decreasing imports or exports, changes in governmental or EU regulations on trade, changes in the exchange rate of the euro, the default or threat of default by an EU member country on its sovereign debt, and/or an economic recession in an EU member country may have a significant adverse effect on the economies of EU member countries and their trading partners. The European financial markets have recently experienced volatility and adverse trends due to concerns about economic downturns, rising government debt levels and the possible default of government debt in several European countries, including Greece, Ireland, Italy, Portugal and Spain. A default or debt restructuring by any European country would adversely impact holders of that country’s debt and sellers of credit default swaps linked to that country’s creditworthiness, which may be located in countries other than those listed in the previous sentence. These events have adversely affected the value and exchange rate of the euro and may continue to significantly affect the economies of every country in Europe, including countries that do not use the euro and non-EU member countries.

Risks of Investing in Non-U.S. Debt Securities. Certain of the Underlying Funds may invest in non-U.S. debt securities. An investment in these Underlying Funds involves risks similar to those of investing in a portfolio of debt securities traded on foreign exchanges and over-the-counter in the respective countries covered by the Underlying Funds. These risks typically include market fluctuations caused by such factors as economic and political developments, changes in interest rates and perceived trends in bond prices. Investing in an Underlying Fund whose portfolio contains non-U.S. issuers involves certain risks and considerations not typically associated with investing in the securities of U.S. issuers. These risks include generally less liquid and less efficient securities markets; generally greater price volatility; less publicly available information about issuers; the imposition of withholding or other taxes; the imposition of restrictions on the expatriation of funds or other assets of the Underlying Fund; higher transaction and custody costs; delays and risks attendant in settlement procedures;

difficulties in enforcing contractual obligations; lower liquidity and significantly smaller market capitalization of most non-U.S. securities markets; different accounting and disclosure standards; lower levels of regulation of the securities markets; more substantial government interference with the economy; higher rates of inflation; greater social, economic, and political uncertainty; and the risk of nationalization or expropriation of assets and risk of war.

Risks of Investing in Russia. Investing in the Russian securities market involves a high degree of risk and special considerations not typically associated with investing in the U.S. securities markets, and should be considered highly speculative. Risks include the absence of developed legal structures governing private and foreign investments and private property; the possibility of the loss of all or a substantial portion of a Fund’s assets invested in Russia as a result of expropriation; certain national policies which may restrict the Fund’s investment opportunities, including, without limitation, restrictions on investing in issuers or industries deemed sensitive to relevant national interests; and potentially greater price volatility in, significantly smaller capitalization of, and relative illiquidity of, the Russian market. There can also be no assurance that a Fund’s investments in these companies would not be expropriated, nationalized or otherwise confiscated. In the event of the settlement of any such claims or such expropriation, nationalization or other confiscation, a Fund could lose its entire investment. In addition, it may be difficult and more costly to obtain and enforce a judgment in the Russian court system.

Russia may also be subject to a greater degree of economic, political and social instability than is the case in other developed countries. Such instability may result from, among other things, the following: (i) an authoritarian government or military involvement in political and economic decision-making, including changes in government through extra-constitutional means; (ii) popular unrest associated with demands for improved political, economic and social conditions; (iii) internal insurgencies; (iv) hostile relations with neighboring countries; and (v) ethnic, religious and racial disaffection.

The Russian economy is heavily dependent upon the export of a range of commodities including most industrial metals, forestry products and oil and gas. Accordingly, it is strongly affected by international commodity prices and is particularly vulnerable to any weakening in global demand for these products. Any acts of terrorism or armed conflicts in Russia or internationally could have an adverse effect on the financial and commodities markets and the global economy. As Russia produces and exports large amounts of crude oil and gas, any acts of terrorism or armed conflict causing disruptions of Russian oil and gas exports could negatively affect the Russian economy and, thus, adversely affect, the financial condition, results of operations or prospects of related companies.

The Russian government may exercise substantial influence over many aspects of the private sector and may own or control many companies. Future government actions could have a significant effect on the economic conditions in Russia, which could have a negative impact on private sector companies. There is also the possibility of diplomatic developments that could adversely affect investments in Russia. In recent years, the Russian government has begun to take bolder steps to re-assert its regional geopolitical influence (including military steps). Such steps may increase tensions between Russia and its neighbors and Western countries and may negatively affect economic growth.

Risks of Investing in the Consumer Discretionary Sector. Companies engaged in the design, production or distribution of products or services for the consumer discretionary sector (including, without limitation, television and radio broadcasting, manufacturing, publishing, recording and musical instruments, motion pictures, photography, amusement and theme parks, gaming casinos, sporting goods and sports arenas, camping and recreational equipment, toys and games, apparel, travel-related services, automobiles, hotels and motels, and fast food and other restaurants) are subject to the risk that their products or services may become obsolete quickly. The consumer discretionary sector can be significantly affected by several factors, including, without limitation, the performance of domestic and international economies, exchange rates, changing consumer tastes and trends, marketing campaigns, cyclical revenue generation, consumer confidence, commodity price volatility, labor relations, interest rates, import and export controls, intense competition, technological developments and government regulation.

Risks of Investing in the Consumer Staples Sector. Companies in the consumer staples sector may be adversely affected by changes in the global economy, consumer spending, competition, demographics and consumer preferences, and production spending. Companies in the consumers staples sector are also affected by changes in government regulation, global economic, environmental and political events, economic conditions and the depletion of resources. In addition, companies in the consumers staples sector may be subject to risks pertaining to the supply of, demand for and prices of raw materials. The

prices of raw materials fluctuate in response to a number of factors, including, without limitation, changes in government agricultural support programs, exchange rates, import and export controls, changes in international agricultural and trading policies, and seasonal and weather conditions.

Risks of Investing in the Energy Sector. Companies in the energy sector are strongly affected by the levels and volatility of global energy prices, energy supply and demand, government regulations and policies, energy production and conservation, efforts and technological change. Prices and supplies of energy may fluctuate significantly over short and long periods of time due to national and international political changes, Organization of Petroleum Exporting Countries (“OPEC”) policies, changes in relationships among OPEC members and between OPEC and oil-importing nations, the regulatory environment, taxation policies, and the economy of the key energy-consuming countries. In addition, companies in the energy sector are at risk of civil liability from accidents resulting in injury, loss of life or property, pollution or other environmental damage claims and risk of loss from terrorism and natural disasters. Disruptions in the oil industry or shifts in fuel consumption may significantly impact companies in this sector. In addition, because a significant portion of revenues of companies in this sector are derived from a relatively small number of customers that are largely composed of governmental entities and utilities, governmental budget constraints may have a significant impact on the stock prices of companies in this industry.

Risks of Investing in the Financial Sector. Companies in the financial sector include regional and money center banks, securities brokerage firms, asset management companies, savings banks and thrift institutions, specialty finance companies (e.g., credit card, mortgage providers), insurance and insurance brokerage firms, financial conglomerates and foreign banking and financial companies. The global financial markets have recently experienced very difficult conditions and volatility as well as significant adverse trends. The deteriorating conditions in these markets have resulted in a decrease in availability of corporate credit, capital and liquidity and have led indirectly to the insolvency, closure or acquisition of a number of financial institutions. These conditions have also contributed to consolidation within the financial industry. In addition, the global financial industry has been materially and adversely affected by a significant decline in the value of mortgage-backed and asset-backed securities, and by the sovereign debt crisis. The prospects of many financial companies are questionable and continue to evolve as financial companies revise their outlooks and write down assets that they hold.

Most financial companies are subject to extensive governmental regulation, which limits their activities and may affect their ability to earn a profit from a given line of business. Government regulation may change frequently and may have significant adverse consequences for companies in the financial sector, including effects not intended by the regulation. Direct governmental intervention in the operations of financial companies and financial markets may materially and adversely affect the companies in which a Fund invests, including recent legislation in many countries that may increase government regulation, repatriation and other intervention. The impact of governmental intervention and recent legislation on any individual financial company or on the financial sector as a whole cannot be predicted. The valuation of financial companies has been and continues to be subject to unprecedented volatility and may be influenced by unpredictable factors, including interest rate risk and sovereign debt default. Certain financial businesses are subject to intense competitive pressures, including market share and price competition. Financial companies in foreign countries are subject to market specific and general regulatory and interest rate concerns. In particular, government regulation in certain foreign countries may include taxes and controls on interest rates, credit availability, minimum capital requirements, ban on short sales, prices and currency transfers.

The profitability of banks, savings and loan associations and financial companies is largely dependent on the availability and cost of capital funds and can fluctuate significantly when interest rates change. In addition, general economic conditions are important to the operations of these concerns, with exposure to credit losses resulting from financial difficulties of borrowers having an adverse effect on the profitability of financial companies. Financial companies can be highly dependent upon access to capital markets and any impediments to such access, such as adverse overall economic conditions or a negative perception in the capital markets of a financial company’s financial condition or prospects, could adversely affect its business.

Risks of Investing in the Health Care Sector. Companies in the health care sector are often issuers whose profitability may be affected by extensive government regulation, restrictions on government reimbursement for medical expenses, rising or falling costs of medical products and services, pricing pressure, an increased emphasis on outpatient services, limited number of products, industry innovation, changes in technologies and other market developments. Many health care companies are heavily dependent on patent protection and the actual or perceived safety and efficiency of their products. The expiration of patents may adversely affect the profitability of these companies. Many health care companies are subject to extensive litigation based on product liability and similar claims. Health care companies are subject to competitive forces

that may make it difficult to raise prices and, in fact, may result in price discounting. Many new products in the health care sector may be subject to regulatory approvals. The process of obtaining such approvals may be long and costly, and may diminish the opportunity for a company to profit from a new product or to bring a new product to market. Many health care-related companies are relatively small and unseasoned. Health care companies may also be strongly affected by scientific bio-technology or technological developments and their products may quickly become obsolete. Also, many health care companies offer products and services that are subject to governmental regulation and may be adversely affected by changes in governmental policies or laws. The impact of recent legislation passed by the U.S. government and other legislation introduced or considered by other governments on any individual health care company or on the health care sector as a whole cannot be predicted. These laws and proposals span a wide range of topics, including cost control, national health insurance, incentives for compensation in the provision of health care services, tax incentives and penalties related to health care insurance premiums, and promotion of prepaid health care plans. No one can predict what proposals will be enacted or what potentially adverse effect they may have on health care-related or biotechnology-related companies.

Risks of Investing in the Industrials Sector. The stock prices of companies in the industrials sector are affected by supply and demand both for their specific product or service and for industrials sector products in general. The products of manufacturing companies may face product obsolescence due to rapid technological developments and frequent new product introduction. Government regulations, world events and economic conditions affect the performance of companies in the industrials sector. Companies in the industrials sector may be adversely affected by liability for environmental damage, product liability claims and exchange rates. The industrials sector may also be adversely affected by changes or trends in commodity prices, which may be influenced by unpredictable factors. Aerospace and defense companies, a component of the industrials sector, can be significantly affected by government spending policies because companies involved in this industry rely, to a significant extent, on U.S. and other government demand for their products and services. Thus, the financial condition of, and investor interest in, aerospace and defense companies are heavily influenced by governmental defense spending policies, which are typically under pressure from efforts to control the U.S. and other government budgets. Transportation stocks, a component of the industrials sector, are cyclical and can be significantly affected by economic changes, fuel prices, labor relations and insurance costs. Transportation companies in certain countries may also be subject to significant government regulation and oversight, which may adversely affect their businesses.

Risks of Investing in the Information Technology Sector. Information technology companies face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Like other technology companies, information technology companies may have limited product lines, markets, financial resources or personnel. The products of information technology companies may face product obsolescence due to rapid technological developments and frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Companies in the information technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies.

Risks of Investing in the Materials Sector. Companies in the materials sector could be adversely affected by commodity price volatility, exchange rates, import controls, increased competition, depletion of resources, technical progress, labor relations, exchange rates and government regulations, among other factors. Also, companies in the materials sector are at risk of liability for environmental damage and product liability claims. Production of materials may exceed demand as a result of market imbalances or economic downturns, leading to poor investment returns.

Risks of Investing in the Utilities Sector. Investments in utility companies involve special considerations, including the risk of changing commodity prices, government regulation stipulating rates charged by utilities, increased tariffs, changes in tax laws, interest rate fluctuations and changes in the cost of providing the specific utility services. The utilities industry is also subject to potential terrorist attacks, natural disasters and severe weather conditions, as well as regulatory and operational burdens associated with the operation and maintenance of nuclear facilities. Government regulators monitor and control utility revenues and costs, and therefore may limit utility profits. In certain countries regulatory authorities may also restrict a company’s access to new markets, thereby diminishing a company’s long-term prospects. The deregulation of certain utilities companies may eliminate restrictions on profits but may also subject these companies to greater risks of loss.

Short-Term Instruments. Each Underlying Fund may invest in short-term instruments in the same manner as the Funds, as described above.

Small-Capitalization Companies Risk. Many of the companies in which the Underlying Funds invest are considered small-capitalization companies. Stock prices of small-capitalization companies may be more volatile than those of larger companies and therefore the Fund’s share price may be more volatile than those of funds that invest a larger percentage of their assets in stocks issued by large-capitalization companies. Stock prices of small-capitalization companies are generally more vulnerable than those of large-capitalization companies to adverse business and economic developments. The stocks of small-capitalization companies may be thinly traded, making it difficult for the Underlying Funds to buy and sell them. In addition, small-capitalization companies are typically less financially stable than larger, more established companies and may depend on a small number of essential personnel, making them more vulnerable to loss of personnel. Small-capitalization companies also normally have less diverse product lines than large-capitalization companies and are more susceptible to adverse developments concerning their products.

Swap Agreements. Swap agreements are contracts between parties in which one party agrees to make periodic payments to the other party based on the change in market value or level of a specified rate, index or asset. In return, the other party agrees to make periodic payments to the first party based on the return of a different specified rate, index or asset. Swap agreements will usually be performed on a net basis, with each Underlying Fund receiving or paying only the net amount of the two payments. The net amount of the excess, if any, of an Underlying Fund’s obligations over its entitlements with respect to each swap is accrued on a daily basis and an amount of liquid assets having an aggregate value at least equal to the accrued excess will be maintained by the Fund.

The use of interest rate and index swaps is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio security transactions. These transactions generally do not involve the delivery of securities or other underlying assets or principal.

Tracking Stocks. A tracking stock is a separate class of common stock whose value is linked to a specific business unit or operating division within a larger company and is designed to “track” the performance of such business unit or division. The tracking stock may pay dividends to shareholders independent of the parent company. The parent company, rather than the business unit or division, generally is the issuer of tracking stock. However, holders of the tracking stock may not have the same rights as holders of the company’s common stock.

U.S. Government Obligations. Certain of the Underlying Funds may invest a portion of their assets in U.S. government obligations and may make such investments in the same manner as the Funds, as described above.

Future Developments. The board of each Underlying Fund may, in the future, authorize each Underlying Fund to invest in securities contracts and investments, other than those listed in this SAI and in the applicable Prospectuses, provided they are consistent with each Underlying Fund’s investment objective and do not violate any investment restrictions or policies.

Proxy Voting Policy

The Trust has adopted, as its proxy voting policies for each Fund, the proxy voting guidelines of BFA, the investment adviser to each Fund. The Trust has delegated to BFA the responsibility for voting proxies on the portfolio securities held by each Fund. The remainder of this section discusses each Fund’s proxy voting guidelines and BFA’s role in implementing such guidelines.

BFA votes (or refrains from voting) proxies for each Fund in a manner that BFA, in the exercise of its independent business judgment, concludes is in the best economic interests of such Fund. In some cases, BFA may determine that it is in the best economic interests of a Fund to refrain from exercising the Fund’s proxy voting rights (such as, for example, proxies on certain non-U.S. securities that might impose costly or time-consuming in-person voting requirements). With regard to the relationship between securities lending and proxy voting, BFA’s approach is also driven by each Fund’s economic interests. The evaluation of the economic desirability of recalling loans involves balancing the revenue-producing value of loans against the likely economic value of casting votes. Based on our evaluation of this relationship, we believe that the likely economic value of casting a vote generally is less than the securities lending income, either because the votes will not have significant economic consequences or because the outcome of the vote would not be affected by BFA recalling loaned securities in order to ensure they are voted. Periodically, BFA analyzes the process and benefits of voting proxies for securities on loan, and will consider whether any modification of its proxy voting policies or procedures are necessary in light of any regulatory changes. BFA will normally vote on specific proxy issues in accordance with its proxy voting guidelines. BFA’s proxy voting guidelines provide detailed guidance as to how to vote proxies on certain important or commonly raised issues. BFA may, in

the exercise of its business judgment, conclude that the proxy voting guidelines do not cover the specific matter upon which a proxy vote is requested, or that an exception to the proxy voting guidelines would be in the best economic interests of a Fund. BFA votes (or refrains from voting) proxies without regard to the relationship of the issuer of the proxy (or any shareholder of such issuer) to a Fund, a Fund’s affiliates (if any), BFA or BFA’s affiliates, or the Distributor or the Distributor’s affiliates. When voting proxies, BFA attempts to encourage issuers to follow practices that enhance shareholder value and increase transparency and allow the market to place a proper value on their assets. With respect to certain specific issues:

  • Each Fund generally supports the board’s nominees in the election of directors and generally supports proposals that strengthen the independence of boards of directors;
  • Each Fund generally does not support proposals on social issues that lack a demonstrable economic benefit to the issuer and the Fund investing in such issuer; and
  • Each Fund generally votes against anti-takeover proposals and proposals that would create additional barriers or costs to corporate transactions that are likely to deliver a premium to shareholders.

BFA maintains institutional policies and procedures that are designed to prevent any relationship between the issuer of the proxy (or any shareholder of the issuer) and a Fund, a Fund’s affiliates (if any), BFA or BFA’s affiliates (if any) or the Distributor or the Distributor’s affiliates, from having undue influence on BFA’s proxy voting activity. In certain instances, BFA may determine to engage an independent fiduciary to vote proxies as a further safeguard against potential conflicts of interest or as otherwise required by applicable law. The independent fiduciary may either vote such proxies or provide BFA with instructions as to how to vote such proxies. In the latter case, BFA votes the proxy in accordance with the independent fiduciary’s determination.

Information with respect to how BFA voted proxies relating to the Funds’ portfolio securities during the 12-month period ended June 30 is available: (i) without charge, upon request, by calling 1-800-iShares (1-800-474-2737) or through the Funds’ website at www.iShares.com; and (ii) on the SEC’s website at www.sec.gov.

Portfolio Holdings Information

The Board has adopted a policy regarding the disclosure of the Funds’ portfolio holdings information that requires that such information be disclosed in a manner that: (i) is consistent with applicable legal requirements and in the best interests of each Fund’s respective shareholders; (ii) does not put the interests of BFA, the Distributor or any affiliated person of BFA or the Distributor, above those of Fund shareholders; (iii) does not advantage any current or prospective Fund shareholders over any other current or prospective Fund shareholders, except to the extent that certain Entities (as described below) may receive portfolio holdings information not available to other current or prospective Fund shareholders in connection with the dissemination of information necessary for transactions in Creation Units, as contemplated by the iShares Exemptive Orders and as discussed below; and (iv) does not provide selective access to portfolio holdings information except pursuant to the procedures outlined below and to the extent appropriate confidentiality arrangements limiting the use of such information are in effect. The “Entities” referred to in sub-section (iii) above are generally limited to National Securities Clearing Corporation (“NSCC”) members, subscribers to various fee-based subscription services, large institutional investors (known as “Authorized Participants”) that have been authorized by the Distributor to purchase and redeem large blocks of shares pursuant to legal requirements, including exemptive orders granted by the SEC pursuant to which the Funds offer and redeem their shares (“iShares Exemptive Orders”) and other institutional market participants and entities that provide information services.

Each business day, each Fund’s portfolio holdings information is provided to the Distributor or other agent for dissemination through the facilities of the NSCC and/or other fee-based subscription services to NSCC members and/or subscribers to those other fee-based subscription services, including Authorized Participants, and to entities that publish and/or analyze such information in connection with the process of purchasing or redeeming Creation Units or trading shares of the Funds in the secondary market. This information typically reflects each Fund’s anticipated holdings on the following business day.

Daily access to information concerning the Funds’ portfolio holdings is permitted (i) to certain personnel of those service providers that are involved in portfolio management and providing administrative, operational, risk management, or other support to portfolio management, including affiliated broker-dealers and Authorized Participants; and (ii) to other personnel of the Funds’ investment adviser and the Distributor, administrator, custodian and fund accountant who deal directly with or assist in, functions related to investment management, distribution, administration, custody and fund accounting, as may be

necessary to conduct business in the ordinary course in a manner consistent with the iShares Exemptive Orders, agreements with the Funds and the terms of the Funds’ current registration statements. In addition, each Fund discloses its portfolio holdings and the percentages they represent of the Fund’s net assets at least monthly, and as often as each day the Fund is open for business, at www.iShares.com. More information about this disclosure is available at www.iShares.com.

Portfolio holdings information made available in connection with the creation/redemption process may be provided to other entities that provide services to the Funds in the ordinary course of business after it has been disseminated to the NSCC. From time to time, information concerning portfolio holdings other than portfolio holdings information made available in connection with the creation/redemption process, as discussed above, may be provided to other entities that provide services to the Funds, including rating or ranking organizations, in the ordinary course of business, no earlier than one business day following the date of the information.

Each Fund discloses its complete portfolio holdings schedule in public filings with the SEC within 70 days after the end of each fiscal quarter and will provide that information to shareholders as required by federal securities laws and regulations thereunder. A Fund may, however, voluntarily disclose all or part of its portfolio holdings other than in connection with the creation/redemption process, as discussed above, in advance of required filings with the SEC, provided that such information is made generally available to all shareholders and other interested parties in a manner that is consistent with the above policy for disclosure of portfolio holdings information. Such information may be made available through a publicly-available website or other means that make the information available to all likely interested parties contemporaneously.

The Trust’s Chief Compliance Officer may authorize disclosure of portfolio holdings information pursuant to the above policy and procedures.

The Board reviews the policy and procedures for disclosure of portfolio holdings information at least annually.

Construction and Maintenance of the Underlying Indexes

Descriptions of the Underlying Indexes are provided below.

The S&P Target Risk Indexes


Index Construction


S&P Target Risk Indexes follow a two step construction process:

1. Each year, S&P estimates the value-weighted market portfolio, which represents a large proportion of globally traded stocks and bonds. To estimate the market portfolio, S&P identifies a group of underlying benchmarks representing asset classes S&P has determined should be included in the market portfolio. As of September 30, 2011, the market portfolio is a value-weighted combination of the following benchmarks: S&P 500 Index, S&P MidCap 400 Index, S&P SmallCap 600 Index, MSCI EAFE Index, MSCI Emerging Markets Index, Barclays Aggregate Bond Index, Barclays Short Treasury Bond Index, Barclays Capital U.S. Treasury Inflation Protected Securities (TIPS) Index (Series-L) and iBoxx $ Liquid High Yield Index.
2. S&P applies shortfall risk constraints to the estimated “market portfolio” for each target risk index to derive the final asset allocation of each index respectively. Each shortfall risk constraint is an estimation of the probability of attaining returns below a certain risk threshold. While S&P’s model is intended to constrain risk, actual losses may significantly exceed the target risk threshold. The shortfall risk constraints and target risk thresholds that S&P derived for each target risk index for 2011 are as follows:
   Conservative Moderate Growth Aggressive
Target Risk Threshold -21% -25% -30% -33%
Probability of Shortfall Risk 18% 22% 26% 30%

Eligible Securities. Each Target Risk Index is comprised exclusively of iShares ETFs. To be eligible for inclusion in an index, an ETF must track a benchmark that is broadly representative of a major asset class and be registered as an investment company under the 1940 Act. As of September 30, 2011 the universe of eligible asset classes and the instruments used to represent each ETF are:

Asset Class iShares ETF
US Large Cap iShares S&P 500 Index Fund
US Mid Cap iShares S&P MidCap 400 Index Fund
US Small Cap iShares S&P SmallCap 600 Index Fund
International Equities iShares MSCI EAFE Index Fund
Emerging Markets iShares MSCI Emerging Markets Index Fund
Core Fixed Income iShares Barclays Aggregate Bond Fund
Short Term Treasuries iShares Barclays Short Treasury Bond Fund
TIPS iShares Barclays TIPS Bond Fund
High Yield Fixed Income iShares iBoxx $ High Yield Corporate Bond Fund

S&P Target Risk Conservative Index Description (as of September 30, 2011, 9 constituent ETFs): The S&P Target Risk Conservative Index is designed to measure the performance of an investment allocation strategy which seeks to emphasize exposure to fixed income, while maintaining smaller equity exposure, in order to produce current income and avoid excessive volatility of returns. S&P determines the underlying index allocation by targeting a mix of securities which could be expected to decrease in value by more than 21% per year with a probability of no more than 18%, as estimated by S&P using a proprietary short-fall risk forecasting methodology.

S&P Target Risk Moderate Index Description (as of September 30, 2011, 9 constituent ETFs): The S&P Target Risk Moderate Index is designed to measure the performance of an investment allocation strategy which seeks to provide significant exposure to fixed income, while also allocating a smaller portion of exposure to equities in order to increase opportunity for capital growth. S&P determines the underlying index allocation by targeting a mix of securities which could be expected to decrease in value by more than 25% per year with a probability of no more than 22%, as estimated by S&P using a proprietary short-fall risk forecasting methodology.

S&P Target Risk Growth Index Description (as of September 30, 2011, 9 constituent ETFs):The S&P Target Risk Growth Index is designed to measure the performance of an investment allocation strategy which seeks to provide exposure to equity securities, while also allocating a portion of exposure to fixed income in an effort to potentially dampen the volatility associated with the returns of equities. S&P determines the underlying index allocation by targeting a mix of securities which could be expected to decrease in value by more than 30% per year with a probability of no more than 26%, as estimated by S&P using a proprietary short-fall risk forecasting methodology.

S&P Target Risk Aggressive Index Description (as of September 30, 2011, 8 constituent ETFs): The S&P Target Risk Aggressive Index is designed to measure the performance of an investment allocation strategy which seeks to provide significant exposure to equities, while also allocating a smaller portion of exposure to fixed income securities in order to increase opportunity for long-term capital growth. S&P determines the underlying index allocation by targeting a mix of securities which could be expected to decrease in value by more than 33% per year with a probability of no more than 30%, as estimated by S&P using a proprietary short-fall risk forecasting methodology.

Index Changes. Index constituents are not expected to change between rebalancing periods. If, for any reason beyond S&P’s control, a constituent is discontinued or substantially changed in terms of its investment mandate, the S&P Index Committee may elect to discontinue representation of the affected asset class within the index or designate a successor fund.


Additions. ETFs may be added to each index to improve its overall representation or investability, such additions being undertaken during a rebalancing period. Other additions, such as those made to replace deleted constituents, may be undertaken in between rebalancing intervals at S&P’s discretion.


Deletions. An ETF may be removed from each index, at S&P’s discretion, if it fails to offer acceptable tracking of its benchmark, for any other reason ceases to function as a reasonable proxy for its benchmark, or in the event of a material event that impairs the operating ability of a fund or its management company.


Rebalancing. Each index is rebalanced annually on the last business day in January of every year, with reference data as of the last business day in December of the prior year.

The S&P Target Date Indexes

Index Construction

The S&P Target Date Index Series is designed to provide exposure to a diversified array of financial assets, as well as to the investment opportunity generally available in target date funds. Each year, S&P conducts a survey of target date funds and combines the raw survey data to derive an allocation strategy for each of its target date indexes. S&P develops the allocation strategy for each target date index using a two-tiered process. The first tier of S&P’s process is to identify and establish exposure levels for asset classes represented by the universe of target date funds. The first tier of the process is as follows:

1. S&P identifies target date funds from Morningstar or Lipper databases and sorts funds by asset size. Funds not meeting the minimum asset threshold of $50 million are removed. If a target date category has less than 15 funds meeting the minimum size threshold, the next smallest funds are used until the universe of funds reaches 15.
2. The latest quarterly holdings filing (Form N-Q) available at SEC’s EDGAR web site are drawn from target date funds which meet the minimum size threshold.
3. Asset class exposures are derived from the eligible fund holdings for each target date category and are aggregated to establish exposures for each S&P Target Date Index.

The second tier of S&P’s process in identifying an allocation strategy for each of its target date indexes is to determine ETF allocation weights for each index that broadly correspond to the asset class exposures identified in its survey process, by applying the following methods and rules:

1. Each constituent asset class in the index must be employed by at least 25% of target date fund sponsors in one or more of their respective funds.
2. For each target date peer group, asset class values either below the 10th percentile or above the 90th percentile of raw values are replaced with the value corresponding to the 10th percentile or the 90th percentile, respectively. This mitigates outlier effects without diminishing the number of survey data points.
3. From the results of step 2, mean values of at least 1% are then proportionately adjusted to create final weights that sum to 100% for each target date index.
4. In order to smooth variations in asset class allocations between target dates, a curve is fitted to the preliminary weight values for each asset class across target dates. Weights must be 0% or greater than or equal to 1%, and they must sum to 100%. Allocations along the fitted curve for each asset class and target date are designated as final index weights.

Eligible Securities. Each S&P Target Date index is comprised exclusively of iShares ETFs. To be eligible for inclusion in an index, an ETF must track a benchmark that is broadly representative of a major asset class and be registered as an investment company under the 1940 Act. As of September 30, 2011 the universe of eligible asset classes and the instruments used to represent each ETF are:

Asset Class iShares ETF
U.S. Large Cap iShares S&P 500 Index Fund
U.S. Mid Cap iShares S&P MidCap 400 Index Fund
U.S. Small Cap iShares S&P SmallCap 600 Index Fund

Rebalancing.
Each index is rebalanced annually on May 30th of every year, with reference data as of April 30th of the prior year.

Investment Limitations

Each Fund has adopted its investment objective as a non-fundamental investment policy. Therefore, each Fund may change its investment objective and its Underlying Index without shareholder approval. The restrictions for each Fund cannot be changed without the approval of the holders of a majority of the applicable Fund’s outstanding voting securities. A vote of a majority of the outstanding voting securities is defined in the 1940 Act as the lesser of (a) 67% or more of the voting securities present at a fund meeting, if the holders of more than 50% of the outstanding voting securities are present or represented by proxy and (b) more than 50% of outstanding voting securities of the fund.

Fundamental Investment Restrictions of the Funds. The Funds have adopted the following investment restrictions as fundamental policies. The Funds may not:

1. Purchase the securities of issuers conducting their principal business activity in the same industry if, immediately after the purchase and as a result thereof, the value of a Fund’s investments in that industry would equal or exceed 25% of the current value of a Fund’s total assets, provided that this restriction does not limit a Fund’s: (i) investments in securities of other investment companies, (ii) investments in securities issued or guaranteed by the U.S. government, its agencies or instrumentalities, or (iii) investments in repurchase agreements collateralized by U.S. government securities.
2. Purchase the securities of any single issuer if, as a result, with respect to 75% of a Fund’s total assets, more than 5% of the value of its total assets would be invested in the securities of such issuer or a Fund’s ownership would be more than 10% of the outstanding voting securities of such issuer, provided that this restriction does not limit a Fund’s cash or cash items, investments in securities issued or guaranteed by the U.S. government, its agencies and instrumentalities, or investments in securities of other investment companies.
3. Borrow money, except that (i) each Fund may borrow from banks for temporary or emergency (not leveraging) purposes, including the meeting of redemption requests which might otherwise require the untimely disposition of securities, and (ii) each Fund may, to the extent consistent with its investment policies, enter into repurchase agreements, reverse repurchase agreements, forward roll transactions and similar investment strategies and techniques. To the extent that it engages in transactions described in (i) and (ii), each Fund will be limited so that no more than 33 1/3% of the value of its total assets (including the amount borrowed) is derived from such transactions. Any borrowings which come to exceed this amount will be reduced in accordance with applicable law.
4. Issue any senior security, except as permitted under the 1940 Act, as amended, and as interpreted, modified or otherwise permitted by regulatory authority having jurisdiction, from time to time.
5. Make loans, except as permitted under the 1940 Act, as interpreted, modified or otherwise permitted by regulatory authority having jurisdiction, from time to time.
6. Engage in the business of underwriting securities issued by other persons, except to the extent that each Fund may technically be deemed to be an underwriter under the Securities Act, in disposing of portfolio securities.
7. Purchase or sell real estate unless acquired as a result of ownership of securities or other instruments (but this restriction shall not prevent each Fund from investing in securities of companies engaged in the real estate business or securities or other instruments backed by real estate or mortgages), or commodities or commodity contracts (but this restriction shall not prevent each Fund from trading in futures contracts and options on futures contracts, including options on currencies to the extent consistent with each Fund’s investment objective and policies).
8. Purchase or sell commodities, provided that (i) currency will not be deemed to be a commodity for purposes of this restriction, (ii) this restriction does not limit the purchase or sale of futures contracts, forward contracts or options, and (iii) this restriction does not limit the purchase or sale of securities or other instruments backed by commodities or the purchase or sale of commodities acquired as a result of ownership of securities or other instruments.

With respect to paragraph (2) above, the 1940 Act currently allows a Fund to borrow up to one-third of the value of its total assets (including the amount borrowed) valued at the lesser of cost or market, less liabilities (not including the amount borrowed) at the time the borrowing is made. With respect to paragraph (4) above, the 1940 Act and regulatory interpretations currently limit the percentage of a Fund’s securities that may be loaned to one-third of the value of its total assets.

Non-Fundamental Investment Restrictions of the Funds. The Funds are subject to the following investment restrictions, all of which are non-fundamental policies:

1. Each Fund may invest in shares of other open-end management investment companies, subject to the limitations of Section 12(d)(1) of the 1940 Act, including the rules, regulations and exemptive orders obtained thereunder. Other investment companies in which a Fund invests can be expected to charge fees for operating expenses, such as investment advisory and administration fees, that would be in addition to those charged by such Fund;
2. Each Fund may not invest more than 15% of its net assets in illiquid securities. For this purpose, illiquid securities include, among others, (i) securities that are illiquid by virtue of the absence of a readily available market or legal or contractual restrictions on resale, (ii) fixed time deposits that are subject to withdrawal penalties and that have maturities of more than seven days, and (iii) repurchase agreements not terminable within seven days;
3. Each Fund may lend securities from its portfolio to brokers, dealers and financial institutions, in amounts not to exceed (in the aggregate) one-third of the Fund’s total assets. Any such loans of portfolio securities will be fully collateralized based on values that are marked-to-market daily;
4. Each Fund may not purchase securities on margin, but each Fund may make margin deposits in connection with transactions in options, forward contracts, futures contracts, including those related to indexes, and options on futures contracts or indexes to the extent permitted under the 1940 Act; and
5. In accordance with Rule 35d-1 under the 1940 Act to invest, under normal circumstances, at least 80% of the value of its net assets, plus the amount of any borrowings for investment purposes, in securities based on its Underlying Index. Each Fund also has adopted a policy to provide its shareholders with at least 60 days’ prior written notice of any change in such policy. If, subsequent to an investment, the 80% requirement is no longer met, a Fund’s future investments will be made in a manner that will bring the Fund into compliance with this policy.

Continuous Offering

The method by which Creation Units are created and traded may raise certain issues under applicable securities laws. Because new Creation Units are issued and sold by the Funds on an ongoing basis, at any point a “distribution,” as such term is used in the 1933 Act, may occur. Broker-dealers and other persons are cautioned that some activities on their part may, depending on the circumstances, result in their being deemed participants in a distribution in a manner that could render them statutory underwriters and subject them to the prospectus delivery requirement and liability provisions of the 1933 Act.

For example, a broker-dealer firm or its client may be deemed a statutory underwriter if it takes Creation Units after placing an order with the Distributor, breaks them down into constituent shares and sells such shares directly to customers or if it chooses to couple the creation of new shares with an active selling effort involving solicitation of secondary market demand for shares. A determination of whether one is an underwriter for purposes of the 1933 Act must take into account all the facts and circumstances pertaining to the activities of the broker-dealer or its client in the particular case and the examples mentioned above should not be considered a complete description of all the activities that could lead to a categorization as an underwriter.

Broker-dealer firms should also note that dealers who are not “underwriters” but are effecting transactions in shares, whether or not participating in the distribution of shares, generally are required to deliver a prospectus. This is because the prospectus delivery exemption in Section 4(3) of the 1933 Act is not available in respect of such transactions as a result of Section 24(d) of the 1940 Act. Firms that incur a prospectus delivery obligation with respect to shares of the Funds are reminded that, pursuant to Rule 153 under the 1933 Act, a prospectus delivery obligation under Section 5(b)(2) of the 1933 Act owed to an exchange member in connection with a sale on the Listing Exchange is satisfied by the fact that the prospectus is available at the Listing Exchange upon request. The prospectus delivery mechanism provided in Rule 153 is available only with respect to transactions on an exchange.

Management

Trustees and Officers. The Board has responsibility for the overall management and operations of the Funds, including general supervision of the duties performed by BFA and other service providers. Each Trustee serves until he or she resigns, is removed, dies, retires or becomes incapacitated. The President, Chief Compliance Officer, Treasurer and Secretary shall each hold office until their successors are chosen and qualified, and all other officers shall hold office until he or she resigns or is removed. Trustees who are not interested persons (as defined in the 1940 Act) are referred to as Independent Trustees.

The registered investment companies advised by BFA or its affiliates are organized into one complex of closed-end funds, two complexes of open-end funds and one complex of exchange-traded funds (“Exchange-Traded Fund Complex”) (each, a “BlackRock Fund Complex”). Each Fund is included in the BlackRock Fund Complex referred to as the Exchange-Traded Fund Complex. Each Trustee also serves as a Director of iShares, Inc. and a Director of iShares MSCI Russia Capped Index Fund, Inc. and, as a result, oversees a total of 229 funds within the Exchange-Traded Fund Complex. With the exception of Robert S. Kapito, the address of each Trustee and officer is c/o BlackRock, Inc., 400 Howard Street, San Francisco, CA 94105. The address of Mr. Kapito is c/o BlackRock, Inc., Park Avenue Plaza, 55 East 52nd Street, New York, NY 10055. The Board has designated George G.C. Parker as its Independent Chairman.

The Board has concluded that, based on each Trustee’s experience, qualifications, attributes or skills on an individual basis and in combination with those of the other Trustees, each Trustee should serve as a Trustee of the Board. Among the attributes common to all Trustees are their ability to review critically, evaluate, question and discuss information provided to them, to interact effectively with the Funds’ investment adviser, other service providers, counsel and the independent registered public accounting firm, and to exercise effective business judgment in the performance of their duties as Trustees. A Trustee’s ability to perform his or her duties effectively may have been attained through the Trustee’s educational background or professional training; business, consulting, public service or academic positions; experience from service as a board member of the Funds and the other funds in the Trust (and any predecessor funds), other investment funds, public companies, or non-profit entities or other organizations; and/or other life experiences.

Board – Leadership Structure and Oversight Responsibilities

Overall responsibility for oversight of the Funds rests with the Board. The Board has engaged BFA to manage the Funds on a day-to-day basis. The Board is responsible for overseeing BFA and other service providers in the operations of the Funds in accordance with the provisions of the 1940 Act, applicable provisions of state and other laws and the Trust’s charter. The Board is currently composed of nine members, seven of whom are Independent Trustees (defined below). The Board currently conducts regular meetings four times a year. In addition, the Board frequently holds special in-person or telephonic meetings or informal conference calls to discuss specific matters that may arise or require action between regular meetings. The Independent Trustees meet regularly outside the presence of management, in executive session or with other service providers to the Trust.

The Board has appointed an Independent Trustee to serve in the role of Chairman. The Chairman’s role is to preside at all meetings of the Board and to act as a liaison with service providers, officers, attorneys, and other Trustees generally between meetings. The Chairman may also perform such other functions as may be delegated by the Board from time to time. The Board has established a Nominating and Governance Committee and an Audit Committee to assist the Board in the oversight and direction of the business and affairs of the Funds, and from time to time may establish ad-hoc committees or informal working groups to review and address the policies and practices of the Funds with respect to certain specified matters. The Board and each standing Committee conduct annual assessments of their oversight function and structure. The Board has determined that the Board’s leadership structure is appropriate because it allows the Board to exercise independent judgment over management and it allocates areas of responsibility among committees of Independent Trustees and the full Board to enhance effective oversight.

Day-to-day risk management with respect to the Funds is the responsibility of BFA or other service providers (depending on the nature of the risk), subject to the supervision of BFA. Each Fund is subject to a number of risks, including investment, compliance, operational and valuation risks, among others. While there are a number of risk management functions performed by BFA and other service providers, as applicable, it is not possible to eliminate all of the risks applicable to the Fund. The Trustees have an oversight role in this area, satisfying themselves that risk management processes are in place and operating effectively. Risk oversight forms part of the Board’s general oversight of each Fund and is addressed as part of various Board and committee activities. The Board, directly or through a committee, also reviews reports from, among others, management and the independent registered public accounting firm for the Trust, as appropriate, regarding risks faced by each Fund and management’s risk functions. The Board has appointed a Chief Compliance Officer who oversees the implementation and testing of the Trust’s compliance program and reports to the Board regarding compliance matters for

the Trust and its principal service providers. In testing and maintaining the compliance program, the Chief Compliance Officer assesses key compliance risks affecting each Fund, and addresses them in reports to the Board. The Independent Trustees have engaged independent legal counsel to assist them in performing their oversight responsibilities.

Committees of the Board of Trustees. Each Trustee who is not an interested person (as defined in the 1940 Act) of the Trust (“Independent Trustee”) serves on the Audit Committee and the Nominating and Governance Committee of the Board. The purposes of the Audit Committee are to assist the Board (i) in its oversight of the Trust’s accounting and financial reporting principles and policies and related controls and procedures maintained by or on behalf of the Trust; (ii) in its oversight of the Trust’s financial statements and the independent audit thereof; (iii) in selecting, evaluating and, where deemed appropriate, replacing the independent accountants (or nominating the independent accountants to be proposed for shareholder approval in any proxy statement); (iv) in evaluating the independence of the independent accountants; (v) in complying with legal and regulatory requirements that relate to the Trust’s accounting and financial reporting, internal controls and independent audits; and (vi) to assume such other responsibilities as may be delegated by the Board. The Audit Committee met five times during the fiscal year ended July 31, 2011.

The Nominating and Governance Committee nominates individuals for Independent Trustee membership on the Board. The Nominating and Governance Committee functions include, but are not limited to, the following: (i) reviewing the qualifications of any person properly identified or nominated to serve as an Independent Trustee; (ii) recommending to the Board and current Independent Trustees the nominee(s) for appointment as an Independent Trustee by the Board and current Independent Trustees and/or for election as Independent Trustees by shareholders to fill any vacancy for a position of Independent Trustee(s) on the Board; (iii) recommending to the Board and current Independent Trustees the size and composition of the Board and Board committees and whether they comply with applicable laws and regulations; (iv) recommending a current Independent Trustee to the Board and current Independent Trustees to serve as Lead Independent Trustee; (v) periodic review of the Board’s retirement policy; and (vi) recommending an appropriate level of compensation for the Independent Trustees for their services as Trustees, members or chairpersons of committees of the Board, Lead Independent Trustee, Chairperson of the Board and any other positions as the Nominating and Governance Committee considers appropriate. The Nominating and Governance Committee does not consider Board nomination(s) recommended by shareholders (acting solely in their capacity as a shareholder and not in any other capacity). The Nominating and Governance Committee is comprised of all members of the Board that are Independent Trustees. The Nominating and Governance Committee met five times during the fiscal year ended July 31, 2011.

Potential Conflicts of Interest. Barclays PLC (“Barclays”) and The PNC Financial Services Group, Inc. (“PNC”), each has a significant economic interest in BlackRock, Inc., the parent of BFA, the Funds’ investment adviser. PNC is considered to be an affiliate of BlackRock, Inc., under the 1940 Act. Certain activities of BlackRock Advisors, LLC, BlackRock, Inc. and their affiliates (collectively, “BlackRock”) and PNC and its affiliates (collectively, “PNC” and together with BlackRock, “Affiliates”), and those of Barclays and its affiliates (collectively, the “Barclays Entities”), with respect to the Funds and/or other accounts managed by BlackRock, PNC or Barclays Entities, may give rise to actual or perceived conflicts of interest such as those described below.

BlackRock is one of the world’s largest asset management firms. PNC is a diversified financial services organization spanning the retail, business and corporate markets. Barclays is a major global financial services provider engaged in a range of activities, including retail and commercial banking, credit cards, investment banking, and wealth management. BlackRock and PNC are affiliates of one another under the 1940 Act. BlackRock, PNC, Barclays and their respective affiliates (including, for these purposes, their directors, partners, trustees, managing members, officers and employees), including the entities and personnel who may be involved in the investment activities and business operations of a Fund, are engaged worldwide in businesses, including equity, fixed income, cash management and alternative investments. These are considerations of which investors in a Fund should be aware, and which may cause conflicts of interest that could disadvantage the Fund and its shareholders. These activities and interests include potential multiple advisory, transactional, financial and other interests in securities and other instruments that may be purchased or sold by a Fund.

BlackRock and its Affiliates, as well as the Barclays Entities, have proprietary interests in, and may manage or advise with respect to, accounts or funds (including separate accounts and other funds and collective investment vehicles) that have investment objectives similar to those of a Fund and/or that engage in transactions in the same types of securities,

currencies and instruments as the Fund. One or more Affiliates and Barclays Entities are also major participants in the global currency, equities, swap and fixed income markets, in each case both on a proprietary basis and for the accounts of customers. As such, one or more Affiliates or Barclays Entities are or may be actively engaged in transactions in the same securities, currencies, and instruments in which a Fund invests. Such activities could affect the prices and availability of the securities, currencies, and instruments in which a Fund invests, which could have an adverse impact on the Fund’s performance. Such transactions, particularly in respect of most proprietary accounts or customer accounts, will be executed independently of a Fund’s transactions and thus at prices or rates that may be more or less favorable than those obtained by the Fund. When BlackRock and its Affiliates purchase or sell the same assets for their managed accounts, including a Fund, the assets actually purchased or sold may be allocated among the accounts on a basis determined in their good faith discretion to be equitable. In some cases, this system may adversely affect the size or price of the assets purchased or sold for a Fund. In addition, transactions in investments by one or more other accounts managed by BlackRock or its Affiliates or a Barclays Entity may have the effect of diluting or otherwise disadvantaging the values, prices or investment strategies of a Fund, particularly, but not limited to, with respect to small capitalization, emerging market or less liquid strategies. This may occur when investment decisions regarding a Fund are based on research or other information that is also used to support decisions for other accounts. When BlackRock or its Affiliates or a Barclays Entity implements a portfolio decision or strategy on behalf of another account ahead of, or contemporaneously with, similar decisions or strategies for a Fund, market impact, liquidity constraints, or other factors could result in the Fund receiving less favorable trading results and the costs of implementing such decisions or strategies could be increased or the Fund could otherwise be disadvantaged. BlackRock or its Affiliates or a Barclays Entity may, in certain cases, elect to implement internal policies and procedures designed to limit such consequences, which may cause a Fund to be unable to engage in certain activities, including purchasing or disposing of securities, when it might otherwise be desirable for it to do so.

Conflicts may also arise because portfolio decisions regarding a Fund may benefit other accounts managed by BlackRock or its Affiliates or a Barclays Entity. For example, the sale of a long position or establishment of a short position by a Fund may impair the price of the same security sold short by (and therefore benefit) one or more Affiliates or Barclays Entities or their other accounts, and the purchase of a security or covering of a short position in a security by a Fund may increase the price of the same security held by (and therefore benefit) one or more Affiliates or Barclays Entities or their other accounts.

BlackRock and its Affiliates or a Barclays Entity and their clients may pursue or enforce rights with respect to an issuer in which a Fund has invested, and those activities may have an adverse effect on the Fund. As a result, prices, availability, liquidity and terms of a Fund’s investments may be negatively impacted by the activities of BlackRock or its Affiliates or a Barclays Entity or their clients, and transactions for the Fund may be impaired or effected at prices or terms that may be less favorable than would otherwise have been the case.

The results of a Fund’s investment activities may differ significantly from the results achieved by BlackRock and its Affiliates or the Barclays Entities for their proprietary accounts or other accounts (including investment companies or collective investment vehicles) managed or advised by them. It is possible that one or more Affiliate- or Barclays Entity-managed accounts and such other accounts will achieve investment results that are substantially more or less favorable than the results achieved by a Fund. Moreover, it is possible that a Fund will sustain losses during periods in which one or more Affiliates or Barclays Entity-managed accounts achieve significant profits on their trading for proprietary or other accounts. The opposite result is also possible. The investment activities of one or more Affiliates or Barclays Entities for their proprietary accounts and accounts under their management may also limit the investment opportunities for a Fund in certain emerging and other markets in which limitations are imposed upon the amount of investment, in the aggregate or in individual issuers, by affiliated foreign investors.

From time to time, a Fund’s activities may also be restricted because of regulatory restrictions applicable to one or more Affiliates or Barclays Entities, and/or their internal policies designed to comply with such restrictions. As a result, there may be periods, for example, when BlackRock, and/or one or more Affiliates or Barclays Entities, will not initiate or recommend certain types of transactions in certain securities or instruments with respect to which BlackRock and/or one or more Affiliates or Barclays Entities are performing services or when position limits have been reached.

In connection with its management of a Fund, BlackRock may have access to certain fundamental analysis and proprietary technical models developed by one or more Affiliates or Barclays Entities. BlackRock will not be under any obligation, however, to effect transactions on behalf of a Fund in accordance with such analysis and models. In addition, neither BlackRock nor any of its Affiliates, nor any Barclays Entity, will have any obligation to make available any information regarding their proprietary activities or strategies, or the activities or strategies used for other accounts managed by them, for

the benefit of the management of a Fund and it is not anticipated that BlackRock will have access to such information for the purpose of managing the Fund. The proprietary activities or portfolio strategies of BlackRock and its Affiliates and the Barclays Entities, or the activities or strategies used for accounts managed by them or other customer accounts could conflict with the transactions and strategies employed by BlackRock in managing a Fund.

In addition, certain principals and certain employees of BlackRock are also principals or employees of Affiliates. As a result, the performance by these principals and employees of their obligations to such other entities may be a consideration of which investors in a Fund should be aware.

BlackRock may enter into transactions and invest in securities, instruments and currencies on behalf of a Fund in which customers of BlackRock or its Affiliates or a Barclays Entity, or, to the extent permitted by the SEC, BlackRock or another Affiliate or a Barclays Entity, serves as the counterparty, principal or issuer. In such cases, such party’s interests in the transaction will be adverse to the interests of the Fund, and such party may have no incentive to assure that the Fund obtains the best possible prices or terms in connection with the transactions. In addition, the purchase, holding and sale of such investments by a Fund may enhance the profitability of BlackRock or its Affiliates or a Barclays Entity. One or more Affiliates or Barclays Entities may also create, write or issue derivatives for their customers, the underlying securities, currencies or instruments of which may be those in which a Fund invests or which may be based on the performance of the Fund. A Fund may, subject to applicable law, purchase investments that are the subject of an underwriting or other distribution by one or more Affiliates or Barclays Entities and may also enter into transactions with other clients of an Affiliate or Barclays Entity where such other clients have interests adverse to those of the Fund.

At times, these activities may cause departments of BlackRock or its Affiliates or a Barclays Entity to give advice to clients that may cause these clients to take actions adverse to the interests of the Fund. To the extent affiliated transactions are permitted, a Fund will deal with BlackRock and its Affiliates or Barclays Entities on an arms-length basis. BlackRock or its Affiliates or a Barclays Entity may also have an ownership interest in certain trading or information systems used by a Fund. A Fund’s use of such trading or information systems may enhance the profitability of BlackRock and its Affiliates or Barclays Entities.

One or more Affiliates or one of the Barclays Entities may act as broker, dealer, agent, lender or adviser or in other commercial capacities for a Fund. It is anticipated that the commissions, mark-ups, mark-downs, financial advisory fees, underwriting and placement fees, sales fees, financing and commitment fees, brokerage fees, other fees, compensation or profits, rates, terms and conditions charged by an Affiliate or Barclays Entity will be in its view commercially reasonable, although each Affiliate or Barclays Entity, including its sales personnel, will have an interest in obtaining fees and other amounts that are favorable to the Affiliate or Barclays Entity and such sales personnel.

Subject to applicable law, the Affiliates and Barclays Entities (and their personnel and other distributors) will be entitled to retain fees and other amounts that they receive in connection with their service to the Funds as broker, dealer, agent, lender, adviser or in other commercial capacities and no accounting to the Funds or their shareholders will be required, and no fees or other compensation payable by the Funds or their shareholders will be reduced by reason of receipt by an Affiliate or Barclays Entity of any such fees or other amounts.

When an Affiliate or Barclays Entity acts as broker, dealer, agent, adviser or in other commercial capacities in relation to the Funds, the Affiliate or Barclays Entity may take commercial steps in its own interests, which may have an adverse effect on the Funds. A Fund will be required to establish business relationships with its counterparties based on the Fund’s own credit standing. Neither BlackRock nor any of the Affiliates, nor any Barclays Entity, will have any obligation to allow their credit to be used in connection with a Fund’s establishment of its business relationships, nor is it expected that the Fund’s counterparties will rely on the credit of BlackRock or any of the Affiliates or Barclays Entities in evaluating the Fund’s creditworthiness.

Purchases and sales of securities for a Fund may be bunched or aggregated with orders for other BlackRock client accounts. BlackRock, however, is not required to bunch or aggregate orders if portfolio management decisions for different accounts are made separately, or if it determines that bunching or aggregating is not practicable or required, or in cases involving client direction.

Prevailing trading activity frequently may make impossible the receipt of the same price or execution on the entire volume of securities purchased or sold. When this occurs, the various prices may be averaged, and the Funds will be charged or credited with the average price. Thus, the effect of the aggregation may operate on some occasions to the disadvantage of

the Funds. In addition, under certain circumstances, the Funds will not be charged the same commission or commission equivalent rates in connection with a bunched or aggregated order.

BlackRock may select brokers (including, without limitation, Affiliates or Barclays Entities) that furnish BlackRock, the Funds, other BlackRock client accounts or other Affiliates or Barclays Entities or personnel, directly or through correspondent relationships, with research or other appropriate services which provide, in BlackRock’s view, appropriate assistance to BlackRock in the investment decision-making process (including with respect to futures, fixed-price offerings and over-the-counter transactions). Such research or other services may include, to the extent permitted by law, research reports on companies, industries and securities; economic and financial data; financial publications; proxy analysis; trade industry seminars; computer data bases; research-oriented software and other services and products. Research or other services obtained in this manner may be used in servicing any or all of the Funds and other BlackRock client accounts, including in connection with BlackRock client accounts other than those that pay commissions to the broker relating to the research or other service arrangements. Such products and services may disproportionately benefit other BlackRock client accounts relative to the Funds based on the amount of brokerage commissions paid by the Funds and such other BlackRock client accounts. For example, research or other services that are paid for through one client’s commissions may not be used in managing that client’s account. In addition, other BlackRock client accounts may receive the benefit, including disproportionate benefits, of economies of scale or price discounts in connection with products and services that may be provided to the Funds and to such other BlackRock client accounts. To the extent that BlackRock uses soft dollars, it will not have to pay for those products and services itself.

BlackRock may receive research that is bundled with the trade execution, clearing, and/or settlement services provided by a particular broker-dealer. To the extent that BlackRock receives research on this basis, many of the same conflicts related to traditional soft dollars may exist. For example, the research effectively will be paid by client commissions that also will be used to pay for the execution, clearing, and settlement services provided by the broker-dealer and will not be paid by BlackRock.

BlackRock may endeavor to execute trades through brokers who, pursuant to such arrangements, provide research or other services in order to ensure the continued receipt of research or other services BlackRock believes are useful in its investment decision-making process. BlackRock may from time to time choose not to engage in the above described arrangements to varying degrees. BlackRock may also enter into commission sharing arrangements under which BlackRock may execute transactions through a broker-dealer, including, where permitted, an Affiliate or Barclays Entity, and request that the broker-dealer allocate a portion of the commissions or commission credits to another firm that provides research to BlackRock. To the extent that BlackRock engages in commission sharing arrangements, many of the same conflicts related to traditional soft dollars may exist.

BlackRock may utilize certain electronic crossing networks (“ECNs”) in executing client securities transactions for certain types of securities. These ECNs may charge fees for their services, including access fees and transaction fees. The transaction fees, which are similar to commissions or markups/markdowns, will generally be charged to clients and, like commissions and markups/markdowns, would generally be included in the cost of the securities purchased. Access fees may be paid by BlackRock even though incurred in connection with executing transactions on behalf of clients, including the Funds. In certain circumstances, ECNs may offer volume discounts that will reduce the access fees typically paid by BlackRock. This would have the effect of reducing the access fees paid by BlackRock. BlackRock will only utilize ECNs consistent with its obligation to seek to obtain best execution in client transactions.

BlackRock has adopted policies and procedures designed to prevent conflicts of interest from influencing proxy voting decisions that it makes on behalf of advisory clients, including the Funds, and to help ensure that such decisions are made in accordance with BlackRock’s fiduciary obligations to its clients. Nevertheless, notwithstanding such proxy voting policies and procedures, actual proxy voting decisions of BlackRock may have the effect of favoring the interests of other clients or businesses of other divisions or units of BlackRock and/or its Affiliates or a Barclays Entity, provided that BlackRock believes such voting decisions to be in accordance with its fiduciary obligations. For a more detailed discussion of these policies and procedures, see the Proxy Voting Policy section of this SAI.

It is also possible that, from time to time, BlackRock or its Affiliates or a Barclays Entity may, although they are not required to, purchase and hold shares of a Fund. Increasing a Fund’s assets may enhance investment flexibility and diversification and may contribute to economies of scale that tend to reduce the Fund’s expense ratio. BlackRock and its Affiliates or Barclays Entities reserve the right to redeem at any time some or all of the shares of a Fund acquired for their own accounts. A large

redemption of shares of a Fund by BlackRock or its Affiliates or by a Barclays Entity could significantly reduce the asset size of the Fund, which might have an adverse effect on the Fund’s investment flexibility, portfolio diversification and expense ratio. BlackRock will consider the effect of redemptions on a Fund and other shareholders in deciding whether to redeem its shares.

It is possible that a Fund may invest in securities of companies with which an Affiliate or a Barclays Entity has or is trying to develop investment banking relationships as well as securities of entities in which BlackRock or its Affiliates or a Barclays Entity has significant debt or equity investments or in which an Affiliate or Barclays Entity makes a market. A Fund also may invest in securities of companies to which an Affiliate or a Barclays Entity provides or may some day provide research coverage. Such investments could cause conflicts between the interests of a Fund and the interests of other clients of BlackRock or its Affiliates or a Barclays Entity. In making investment decisions for a Fund, BlackRock is not permitted to obtain or use material non-public information acquired by any division, department or Affiliate of BlackRock or of a Barclays Entity in the course of these activities. In addition, from time to time, the activities of an Affiliate or a Barclays Entity may limit a Fund’s flexibility in purchases and sales of securities. When an Affiliate is engaged in an underwriting or other distribution of securities of an entity, BlackRock may be prohibited from purchasing or recommending the purchase of certain securities of that entity for a Fund.

BlackRock and its Affiliates and the Barclays Entities, their personnel and other financial service providers may have interests in promoting sales of the Funds. With respect to BlackRock and its Affiliates and Barclays Entities and their personnel, the remuneration and profitability relating to services to and sales of the Funds or other products may be greater than remuneration and profitability relating to services to and sales of certain funds or other products that might be provided or offered. BlackRock and its Affiliates or Barclays Entities and their sales personnel may directly or indirectly receive a portion of the fees and commissions charged to the Funds or their shareholders. BlackRock and its advisory or other personnel may also benefit from increased amounts of assets under management. Fees and commissions may also be higher than for other products or services, and the remuneration and profitability to BlackRock or its Affiliates or a Barclays Entity and such personnel resulting from transactions on behalf of or management of the Funds may be greater than the remuneration and profitability resulting from other funds or products.

BlackRock and its Affiliates or a Barclays Entity and their personnel may receive greater compensation or greater profit in connection with an account for which BlackRock serves as an adviser than with an account advised by an unaffiliated investment adviser. Differentials in compensation may be related to the fact that BlackRock may pay a portion of its advisory fee to its Affiliate or to a Barclays Entity, or relate to compensation arrangements, including for portfolio management, brokerage transactions or account servicing. Any differential in compensation may create a financial incentive on the part of BlackRock or its Affiliates or Barclays Entities and their personnel to recommend BlackRock over unaffiliated investment advisers or to effect transactions differently in one account over another.

BlackRock and its Affiliates or a Barclays Entity may provide valuation assistance to certain clients with respect to certain securities or other investments and the valuation recommendations made for their clients’ accounts may differ from the valuations for the same securities or investments assigned by a Fund’s pricing vendors, especially if such valuations are based on broker-dealer quotes or other data sources unavailable to the Fund’s pricing vendors. While BlackRock will generally communicate its valuation information or determinations to a Fund’s pricing vendors and/or fund accountants, there may be instances where the Fund’s pricing vendors or fund accountants assign a different valuation to a security or other investment than the valuation for such security or investment determined or recommended by BlackRock.

As disclosed in more detail in the Determination of Net Asset Value section of each Fund’s Prospectus, when market valuations are not readily available or such valuations do not reflect current market values, the affected investments will be valued using fair value pricing, pursuant to procedures adopted by the Fund’s Board. As a result, the Funds’ sale or redemption of its shares at net asset value, at a time when a holding or holdings are valued by BlackRock (pursuant to Board-adopted procedures) at fair value, may have the effect of diluting or increasing the economic interest of existing shareholders.

To the extent permitted by applicable law, a Fund may invest all or some of its short term cash investments in any money market fund or similarly-managed private fund advised or managed by BlackRock. In connection with any such investments, a Fund, to the extent permitted by the 1940 Act, may pay its share of expenses of a money market fund in which it invests, which may result in a Fund bearing some additional expenses.

BlackRock and its Affiliates or a Barclays Entity and their directors, officers and employees, may buy and sell securities or other investments for their own accounts, and may have conflicts of interest with respect to investments made on behalf of a Fund. As a result of differing trading and investment strategies or constraints, positions may be taken by directors, officers, employees and Affiliates of BlackRock or by Barclays Entities that are the same, different from or made at different times than positions taken for the Fund. To lessen the possibility that a Fund will be adversely affected by this personal trading, the Fund, BFA and BlackRock each has adopted a Code of Ethics in compliance with Section 17(j) of the 1940 Act that restricts securities trading in the personal accounts of investment professionals and others who normally come into possession of information regarding the Fund’s portfolio transactions. Each Code of Ethics can be reviewed and copied at the SEC’s Public Reference Room in Washington, D.C. Information on the operation of the Public Reference Room may be obtained by calling the SEC at (202) 551-8090. Each Code of Ethics is also available on the EDGAR Database on the SEC’s Internet site at http://www.sec.gov, and copies may be obtained, after paying a duplicating fee, by e-mail at publicinfo@sec.gov or by writing the SEC’s Public Reference Section, Washington, DC 20549-1520.

BlackRock and its Affiliates will not purchase securities or other property from, or sell securities or other property to, a Fund, except that the Fund may in accordance with rules adopted under the 1940 Act engage in transactions with accounts that are affiliated with the Fund as a result of common officers, directors, or investment advisers or pursuant to exemptive orders granted to the Funds and/or BlackRock by the SEC. These transactions would be affected in circumstances in which BlackRock determined that it would be appropriate for the Fund to purchase and another client of BlackRock to sell, or the Fund to sell and another client of BlackRock to purchase, the same security or instrument on the same day. From time to time, the activities of a Fund may be restricted because of regulatory requirements applicable to BlackRock or its Affiliates or a Barclays Entity and/or BlackRock’s internal policies designed to comply with, limit the applicability of, or otherwise relate to such requirements. A client not advised by BlackRock would not be subject to some of those considerations. There may be periods when BlackRock may not initiate or recommend certain types of transactions, or may otherwise restrict or limit their advice in certain securities or instruments issued by or related to companies for which an Affiliate or a Barclays Entity is performing investment banking, market making or other services or has proprietary positions. For example, when an Affiliate is engaged in an underwriting or other distribution of securities of, or advisory services for, a company, the Funds may be prohibited from or limited in purchasing or selling securities of that company. Similar situations could arise if personnel of BlackRock or its Affiliates or a Barclays Entity serve as directors of companies the securities of which the Funds wish to purchase or sell. However, if permitted by applicable law, the Funds may purchase securities or instruments that are issued by such companies or are the subject of an underwriting, distribution, or advisory assignment by an Affiliate or a Barclays Entity, or in cases in which personnel of BlackRock or its Affiliates or of Barclays Entities are directors or officers of the issuer.

The investment activities of one or more Affiliates or Barclays Entities for their proprietary accounts and for client accounts may also limit the investment strategies and rights of the Funds. For example, in regulated industries, in certain emerging or international markets, in corporate and regulatory ownership definitions, and in certain futures and derivative transactions, there may be limits on the aggregate amount of investment by affiliated investors that may not be exceeded without the grant of a license or other regulatory or corporate consent or, if exceeded, may cause BlackRock, the Funds or other client accounts to suffer disadvantages or business restrictions.

If certain aggregate ownership thresholds are reached or certain transactions undertaken, the ability of BlackRock on behalf of clients (including the Funds) to purchase or dispose of investments, or exercise rights or undertake business transactions, may be restricted by regulation or otherwise impaired. As a result, BlackRock, on behalf of clients (including the Funds), may limit purchases, sell existing investments, or otherwise restrict or limit the exercise of rights (including voting rights) when BlackRock, in its sole discretion, deems it appropriate.

BlackRock and its Affiliates and Barclays Entities may maintain securities indices as part of their product offerings. Index based funds seek to track the performance of securities indices and may use the name of the index in the fund name. Index providers, including BlackRock and its Affiliates and Barclays Entities may be paid licensing fees for use of their index or index name. BlackRock and its Affiliates and Barclays Entities will not be obligated to license their indices to BlackRock, and BlackRock cannot be assured that the terms of any index licensing agreement with BlackRock and its Affiliates and Barclays Entities will be as favorable as those terms offered to other index licensees.

BlackRock and its Affiliates and Barclays Entities may serve as Authorized Participants in the creation and redemption of exchange-traded funds, including funds advised by Affiliates of BlackRock. As described in greater detail in the Creations and Redemptions section of the prospectus, BlackRock and its Affiliates and Barclays Entities may therefore be deemed to be participants in a distribution of iShares funds that could render them statutory underwriters.

Present and future activities of BlackRock and its Affiliates and Barclays Entities, including BlackRock Advisors, LLC, in addition to those described in this section, may give rise to additional conflicts of interest.

Investment Advisory, Administrative and Distribution Services

Investment Adviser. BFA serves as investment adviser to each Fund pursuant to an Investment Advisory Agreement between the Trust, on behalf of each Fund, and BFA. BFA is a California corporation indirectly owned by BlackRock, Inc. and is registered as an investment adviser under the Investment Advisers Act of 1940, as amended. Under the Investment Advisory Agreement, BFA, subject to the supervision of the Board and in conformity with the stated investment policies of each Fund, manages and administers the Trust and the investment of each Fund’s assets. BFA is responsible for placing purchase and sale orders and providing continuous supervision of the investment portfolio of each Fund.

Pursuant to the Investment Advisory Agreement, BFA may, from time to time, in its sole discretion and to the extent permitted by applicable law, appoint one or more sub-advisers, including, without limitation, affiliates of BFA, to perform investment advisory or other services with respect to a Fund. In addition, BFA may delegate certain of its investment advisory functions under the Investment Advisory Agreement to one or more of its affiliates to the extent permitted by applicable law. BFA may terminate any or all sub-advisers or such delegation arrangements in its sole discretion upon appropriate notice at any time to the extent permitted by applicable law.

Pursuant to the Investment Advisory Agreement, BFA is responsible for substantially all expenses of the Funds, including the cost of transfer agency, custody, fund administration, legal, audit and other services. BFA is not responsible for, and the Funds will bear the cost of, interest expense, taxes, brokerage expenses and other expenses connected with the execution of portfolio securities transactions, distribution fees and extraordinary expenses.



For its investment management services to each Fund, BFA received a management fee at the annual rates (as a percentage of such Fund’s average net assets) set forth below for the fiscal year ended July 31, 2011. BFA has entered into a Fee Waiver Agreement with the Trust, under which BFA agrees to waive a portion of the management fee that it is entitled to receive from each Fund in an amount equal to 0.14%. The Fee Waiver Agreement remains in effect until June 30, 2013. After giving effect to the fee waiver, BFA will receive a management fee based on a percentage of each Fund’s average daily net assets, at the annual rate of 0.11%.

The Investment Advisory Agreement with respect to each Fund continues in effect for two years from its effective date, and thereafter is subject to annual approval by (i) the Board, or (ii) the vote of a majority of the outstanding voting securities (as defined in the 1940 Act) of the applicable Fund, provided that in either event such continuance also is approved by a majority of the Board who are not interested persons (as defined in the 1940 Act) of the applicable Fund, by a vote cast in person at a meeting called for the purpose of voting on such approval.

The Investment Advisory Agreement with respect to each Fund is terminable without penalty, on 60 days’ notice, by the Board or by a vote of the holders of a majority of the applicable Fund’s outstanding voting securities (as defined in the 1940 Act). The Investment Advisory Agreement is also terminable upon 60 days’ notice by BFA and will terminate automatically in the event of its assignment (as defined in the 1940 Act).

Current interpretations of U.S. federal banking laws and regulations (i) may prohibit BlackRock, Inc., BTC and BFA from controlling or underwriting the shares of the Funds, but (ii) do not prohibit BlackRock, Inc. or BFA generally from acting as an investment adviser, administrator, transfer agent or custodian to the Funds or from purchasing shares as agent for and upon the order of a customer.

BFA believes that it may perform advisory and related services for the Trust without violating applicable banking laws or regulations. However, the legal requirements and interpretations about the permissible activities of banks and their affiliates may change in the future. These changes could prevent BFA from continuing to perform services for the Trust. If this happens, the Board would consider selecting other qualified firms. Any new investment advisory agreement would be subject to shareholder approval.

If current restrictions on bank activities with mutual funds were relaxed, BFA, or its affiliates, would consider performing additional services for the Trust. BFA cannot predict whether these changes will be enacted, or the terms under which BFA, or its affiliates, might offer to provide additional services.

Underlying Funds. BFA serves as investment adviser to each of the Underlying Funds. Each Fund, as a shareholder of the Underlying Funds, bears a pro rata share of the Underlying Funds’ advisory fees, which are based on aggregate net assets, as listed in the chart below. Please note that the list of Underlying Funds below is as of September 30, 2011, but BFA may add, eliminate or replace Underlying Funds at any time.

iShares Barclays Short Treasury Bond Fund 0.15%
iShares Barclays TIPS Bond Fund 0.20%
iShares iBoxx $ High Yield Corporate Bond Fund 0.50%

(1) For its investment advisory services to the iShares MSCI EAFE Index Fund, BFA is entitled to receive a management fee from the fund corresponding to each Fund’s allocable portion of an aggregate management fee based on the average daily net assets of the following iShares funds: iShares MSCI ACWI Index Fund, iShares MSCI ACWI ex US Index Fund, iShares MSCI All Country World Minimum Volatility Index Fund, iShares MSCI EAFE Index Fund and iShares MSCI EAFE Minimum Volatility Index Fund. The aggregate management fee is calculated as follows: 0.35% per annum of the aggregate net assets less than or equal to $30 billion, plus 0.32% per annum of the aggregate net assets over $30.0 billion, up to and including $60.0 billion, plus 0.28% per annum of the aggregate net assets in excess of $60.0 billion.
(2) For its investment advisory services to the iShares MSCI Emerging Markets Index Fund, BFA is entitled to receive a management fee from the fund corresponding to each Fund’s allocable portion of an aggregate management fee based on the average daily net assets of the following iShares Funds: iShares MSCI All Country Asia ex Japan Index Fund, iShares MSCI BRIC Index Fund, iShares MSCI Emerging Markets Eastern Europe Index Fund, iShares MSCI Emerging Markets Financials Sector Index Fund, iShares MSCI Emerging Markets Index Fund, iShares MSCI Emerging Markets Materials Sector Index Fund, iShares MSCI Emerging Markets Minimum Volatility Index Fund and iShares MSCI Emerging Markets Small Cap Index Fund. The aggregate management fee is calculated as follows: 0.75% per annum of the aggregate net assets less than or equal to $14.0 billion, plus 0.68% per annum of the aggregate net assets over $14.0 billion, up to and including $28.0 billion, plus 0.61% per annum of the aggregate net assets over $28.0 billion, up to and including $42.0 billion, plus 0.56% per annum of the aggregate net assets over $42.0 billion, up to and including $56.0 billion plus 0.50% per annum of the aggregate net assets over $56.0 billion, up to and including $70.0 billion plus 0.45% per annum of the aggregate net assets over $70.0 billion, up to and including $84.0 billion plus 0.40% per annum of the aggregate net assets in excess of $84.0 billion.

Portfolio Managers. As of July 31, 2011, the individuals named as Portfolio Managers in the Funds’ Prospectuses were also primarily responsible for the day-to-day management of other iShares funds and certain other types of portfolios and/or accounts as indicated in the tables below:

Each of the portfolios or accounts for which the Portfolio Managers are primarily responsible for the day-to-day management seeks to track the rate of return, risk profile and other characteristics of independent third-party indexes by either replicating the same combination of securities that constitute those indexes or through a representative sampling of the securities that

constitute those indexes based on objective criteria and data. Pursuant to BTC and BFA policy, investment opportunities are allocated equitably among the Funds and other portfolios and accounts. For example, under certain circumstances, an investment opportunity may be restricted due to limited supply on the market, legal constraints or other factors, in which event the investment opportunity will be allocated equitably among those portfolios and accounts, including the Funds seeking such investment opportunity. As a consequence, from time to time the Funds may receive a smaller allocation of an investment opportunity than they would have if the Portfolio Managers and BFA and its affiliates did not manage other portfolios or accounts.

Like the Funds, the other portfolios or accounts for which the Portfolio Managers are primarily responsible for the day-to-day portfolio management generally pay an asset-based fee to BFA or BTC, as applicable, for its advisory services. One or more of those other portfolios or accounts, however, may pay BTC an incentive-based fee in lieu of, or in addition to, an asset-based fee for its advisory services. A portfolio or account with an incentive-based fee would pay BTC a portion of that portfolio’s or account’s gains, or would pay BTC more for its services than would otherwise be the case if BTC meets or exceeds specified performance targets. By their nature, incentive-based fee arrangements could present an incentive for BTC to devote greater resources, and allocate more investment opportunities, to the portfolios or accounts that have those fee arrangements, relative to other portfolios or accounts, in order to earn larger fees. Although BTC has an obligation to allocate resources and opportunities equitably among portfolios and accounts and intends to do so, shareholders of the Funds should be aware that, as with any group of portfolios and accounts managed by an investment adviser and/or its affiliates pursuant to varying fee arrangements, including incentive-based fee arrangements, there is the potential for a conflict of interest that may result in the Portfolio Managers’ favoring those portfolios or accounts with incentive-based fee arrangements.

The tables below show, for each Portfolio Manager, the number of portfolios or accounts of the types set forth in the above tables and the aggregate of total assets in those portfolios or accounts with respect to which the investment management fees are based on the performance of those portfolios or accounts as of July 31, 2011:

The discussion below describes the Portfolio Managers’ compensation as of July 31, 2011.

Portfolio Manager Compensation Overview

Base compensation. Generally, portfolio managers receive base compensation based on their seniority and/or their position with the firm. Senior portfolio managers who perform additional management functions within the portfolio management group or within BlackRock may receive additional compensation for serving in these other capacities.

Discretionary Incentive Compensation. Discretionary incentive compensation is a function of several components: the performance of BlackRock, Inc., the performance of the portfolio manager’s group within BlackRock, the investment performance, including risk-adjusted returns, of the firm’s assets under management or supervision by that portfolio manager relative to predetermined benchmarks, and the individual’s seniority, role within the portfolio management team, teamwork and contribution to the overall performance of these portfolios and BlackRock.

Distribution of Discretionary Incentive Compensation. Discretionary incentive compensation is distributed to portfolio managers in a combination of cash and BlackRock, Inc. restricted stock units which vest ratably over a number of years. The BlackRock, Inc. restricted stock units, if properly vested, will be settled in BlackRock, Inc. common stock. Typically, the cash bonus, when combined with base salary, represents more than 60% of total compensation for the portfolio managers. Paying a portion of annual bonuses in stock puts compensation earned by a portfolio manager for a given year “at risk” based on BlackRock’s ability to sustain and improve its performance over future periods.

From time to time, long-term incentive equity awards are granted to certain key employees to aid in retention, align their interests with long-term shareholder interests and motivate performance. Equity awards are generally granted in the form of BlackRock, Inc. restricted stock units that, once vested, settle in BlackRock, Inc. common stock.

As of July 31, 2011 (September 1, 2011 for the iShares S&P Target Date 2045 Index Fund and iShares S&P Target Date 2050 Index Fund), the Portfolio Managers beneficially owned shares of the Funds, for which they are primarily responsible for the day-to-day management, in the amounts reflected in the following tables:

Codes of Ethics. The Trust, BFA and the Distributor have adopted Codes of Ethics pursuant to Rule 17j-1 of the 1940 Act. The Codes of Ethics permit personnel subject to the Codes of Ethics to invest in securities, subject to certain limitations, including securities that may be purchased or held by the Funds. The Codes of Ethics are on public file with, and are available from, the SEC.

Anti-Money Laundering Requirements. The Funds are subject to the USA PATRIOT Act (the “Patriot Act”). The Patriot Act is intended to prevent the use of the U.S. financial system in furtherance of money laundering, terrorism or other illicit activities. Pursuant to requirements under the Patriot Act, a Fund may request information from Authorized Participants to enable it to form a reasonable belief that it knows the true identity of its Authorized Participants. This information will be used to verify the identity of Authorized Participants or, in some cases, the status of financial professionals; it will be used only for compliance with the requirements of the Patriot Act.

The Funds reserve the right to reject purchase orders from persons who have not submitted information sufficient to allow the Fund to verify their identity. Each Fund also reserves the right to redeem any amounts in a Fund from persons whose identity it is unable to verify on a timely basis. It is the Funds’ policy to cooperate fully with appropriate regulators in any investigations conducted with respect to potential money laundering, terrorism or other illicit activities.

Administrator, Custodian and Transfer Agent. State Street Bank and Trust Company (“State Street”) serves as administrator, custodian and transfer agent for the Funds under the Master Services Agreement and related Service Schedule (the “Service Module”). State Street’s principal address is 200 Clarendon Street, Boston, MA 02116. Pursuant to the Service Module for Fund Administration and Accounting Services with the Trust, State Street provides necessary administrative, legal, tax and accounting and financial reporting services for the maintenance and operations of the Trust and each Fund. In

addition, State Street makes available the office space, equipment, personnel and facilities required to provide such services. Pursuant to the Service Module for Custodial Services with the Trust, State Street maintains, in separate accounts, cash, securities and other assets of the Trust and each Fund, keeps all necessary accounts and records and provides other services. State Street is required, upon the order of the Trust, to deliver securities held by State Street and to make payments for securities purchased by the Trust for each Fund. State Street is authorized to appoint certain foreign custodians or foreign custody managers for Fund investments outside the United States. Pursuant to the Service Module for Transfer Agency Services with the Trust, State Street acts as a transfer agent for each Fund’s authorized and issued shares of beneficial interest, and as dividend disbursing agent of the Trust. As compensation for these services, State Street receives certain out-of-pocket costs, transaction fees and asset-based fees which are accrued daily and paid monthly by BFA from its management fee.

Distributor. The Distributor’s principal address is One Freedom Valley Drive, Oaks, PA 19456. The Distributor has entered into a Distribution Agreement with the Trust pursuant to which it distributes shares of each Fund. The Distribution Agreement will continue for two years from its effective date and is renewable annually. Shares are continuously offered for sale by the Funds through the Distributor only in Creation Units, as described in the applicable Prospectus and below in the Creation and Redemption of Creation Units section of this SAI. Fund shares in amounts less than Creation Units are not distributed by the Distributor. The Distributor will deliver the applicable Prospectus and, upon request, the SAI to persons purchasing Creation Units and will maintain records of both orders placed with it and confirmations of acceptance furnished by it. The Distributor is a broker-dealer registered under the Securities Exchange Act of 1934, as amended (the “1934 Act”), and a member of the Financial Industry Regulatory Authority, Inc. (“FINRA”).

The Distribution Agreement for each Fund provides that it may be terminated at any time, without the payment of any penalty, on at least 60 days’ prior written notice to the other party following (i) the vote of a majority of the Independent Trustees, or (ii) the vote of a majority of the outstanding voting securities (as defined in the 1940 Act) of the relevant Fund. The Distribution Agreement will terminate automatically in the event of its assignment (as defined in the 1940 Act).

The Distributor may also enter into agreements with securities dealers (“Soliciting Dealers”) who will solicit purchases of Creation Units of Fund shares. Such Soliciting Dealers may also be Authorized Participants (as defined below), DTC participants and/or investor services organizations.

BFA or BTC may, from time to time and from its own resources, pay, defray or absorb costs relating to distribution, including payments out of its own resources to the Distributor, or to otherwise promote the sale of shares.

The following table sets forth the compensation paid by BFA to the Distributor for certain services, not primarily intended to result in the sale of Fund shares, provided to each Fund during the fiscal years noted:

Financial Intermediary Compensation. BFA and/or BTC and/or their respective subsidiaries (“BFA Entities”) pay certain broker-dealers, banks and other financial intermediaries (“Intermediaries”) for certain activities related to the Funds, other iShares funds or exchange-traded products in general (“Payments”). BFA Entities make Payments from their own assets and not from the assets of the Funds. Although a portion of BFA Entities’ revenue comes directly or indirectly in part from fees paid by the Funds and other iShares funds, Payments do not increase the price paid by investors for the purchase of shares of, or the cost of owning, the Fund or other iShares funds. BFA Entities make Payments for Intermediaries’ participating in activities that are designed to make registered representatives, other professionals and individual investors more knowledgeable about exchange-traded products, including the Funds or for other activities, such as participation in marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems (“Education Costs”). BFA Entities also make Payments to Intermediaries for certain printing, publishing and mailing costs associated with the Funds or materials relating to exchange-traded products in general (“Publishing Costs”). In addition, BFA Entities make Payments to Intermediaries that make shares of the Funds and certain other iShares funds available to their clients, develop new products that feature iShares or otherwise promote the Funds and other iShares funds. Payments of this type are sometimes referred to as revenue-sharing payments.

Payments to an Intermediary may be significant to the Intermediary, and amounts that Intermediaries pay to your salesperson or other investment professional may also be significant for your salesperson or other investment professional. Because an Intermediary may make decisions about which investment options it will recommend or make available to its clients or what services to provide for various products based on payments it receives or is eligible to receive, Payments create conflicts of interest between the Intermediary and its clients and these financial incentives may cause the Intermediary to recommend the Fund and other iShares funds over other investments. The same conflict of interest exists with respect to your salesperson or other investment professional if he or she receives similar payments from his or her Intermediary firm.

As of February 2, 2010, BFA Entities had arrangements to make Payments other than Education Costs or Publishing Costs only to Fidelity Brokerage Services LLC (“FBS”) and Merrill Lynch, Pierce, Fenner & Smith, Inc. (“ML”). Pursuant to BFA Entities’ arrangement with FBS, FBS has agreed to promote iShares funds to FBS’s customers and not to charge certain of its customers any commissions when those customers purchase or sell shares of certain iShares funds online (the “Co-Branded Marketing Program”). BFA Entities have agreed to facilitate the Co-Branded Marketing Program by making payments to FBS during the term of the agreement in a fixed amount. Upon termination of the agreement the BFA Entities will make additional

payments to FBS based upon a number of criteria, including the overall success of the Co-Branded Marketing program and the level of services provided by FBS during the wind-down period. Pursuant to BFA Entities’ arrangement with ML, BFA Entities have agreed to reimburse ML for a portion of certain fee waivers that ML may be required to implement with respect to accounts that hold “plan assets” within the meaning of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”), as a consequence of a technical ERISA affiliate relationship between BFA and ML.

Any additions, modifications, or deletions to Intermediaries listed above that have occurred since the date noted above are not included in the list. Further, BFA Entities make Education Costs and Publishing Costs Payments to other Intermediaries that are not listed above. BFA Entities may determine to make Payments based on any number of metrics. For example, BFA Entities may make Payments at year-end or other intervals in a fixed amount, an amount based upon an Intermediary’s services at defined levels or an amount based on the Intermediary’s net sales of one or more iShares funds in a year or other period, any of which arrangements may include an agreed-upon minimum or maximum payment, or any combination of the foregoing. As of the date of this SAI, BFA anticipates that the Payments paid by BFA Entities in connection with the Funds, iShares funds and exchange-traded products in general will be immaterial to BFA Entities in the aggregate for the next year. Please contact your salesperson or other investment professional for more information regarding any Payments his or her Intermediary firm may receive. Any Payments made by the BFA Entities to an Intermediary may create the incentive for an Intermediary to encourage customers to buy shares of iShares funds.

Brokerage Transactions

BFA assumes general supervision over placing orders on behalf of each Fund for the purchase and sale of portfolio securities. In selecting brokers or dealers for any transaction in portfolio securities, BFA’s policy is to make such selection based on factors deemed relevant, including but not limited to, the breadth of the market in the security, the price of the security, the reasonableness of the commission or mark-up or mark-down, if any, execution capability, settlement capability, back office efficiency and the financial condition of the broker or dealer, both for the specific transaction and on a continuing basis. The overall reasonableness of brokerage commissions paid is evaluated by BFA based upon its knowledge of available information as to the general level of commissions paid by other institutional investors for comparable services. Brokers may also be selected because of their ability to handle special or difficult executions, such as may be involved in large block trades, less liquid securities, broad distributions, or other circumstances. BFA does not consider the provision or value of research, products or services a broker or dealer may provide, if any, as a factor in the selection of a broker or dealer or the determination of the reasonableness of commissions paid in connection with portfolio transactions. The Trust has adopted policies and procedures that prohibit the consideration of sales of a Fund’s shares as a factor in the selection of a broker or a dealer to execute its portfolio transactions.

The table below sets forth the brokerage commissions paid by each Fund for the fiscal years noted. Any differences in brokerage commissions paid by a Fund from year to year are due to increases or decreases in that Fund’s assets over those periods:

None of the Funds paid any brokerage commissions to BlackRock, an affiliate of BFA, and a subsidiary of BTC, during the fiscal year ended July 31, 2011.

The Funds’ purchase and sale orders for securities may be combined with those of other investment companies, clients or accounts that BFA or its Affiliates manage or advise and for which they have brokerage placement authority. If purchases or sales of portfolio securities of the Funds and one or more other accounts managed or advised by BFA or its Affiliates are considered at or about the same time, transactions in such securities are allocated among the Funds and the other accounts in a manner deemed equitable to all by BFA and its Affiliates. In some cases, this procedure could have a detrimental effect on the price or volume of the security as far as the Funds are concerned. However, in other cases, it is possible that the ability to participate in volume transactions and to negotiate lower transaction costs will be beneficial to the Funds. BFA and its Affiliates may deal, trade and invest for their own account in the types of securities in which the Funds may invest. BFA and its Affiliates may, from time to time, effect trades on behalf of and for the account of the Funds with brokers or dealers that are affiliated with BFA, in conformity with the 1940 Act and SEC rules and regulations. Under these provisions, any commissions paid to affiliated brokers or dealers must be reasonable and fair compared to the commissions charged by other brokers or dealers in comparable transactions. The Funds will not deal with affiliates in principal transactions unless permitted by applicable SEC rules or regulations, or by SEC exemptive order.

Portfolio turnover may vary from year to year, as well as within a year. High turnover rates may result in comparatively greater brokerage expenses. The table below sets forth the portfolio turnover rates of each Fund for the fiscal years noted:

Fund Fiscal Year Ended July 31, 2011 Fiscal Year Ended July 31, 2010

Additional Information Concerning the Trust

Shares. The Trust currently consists of more than 190 separate investment series or portfolios called funds. The Trust issues shares of beneficial interests in each fund with no par value. The Board may designate additional iShares funds.

Each share issued by a fund has a pro rata interest in the assets of that fund. Shares have no preemptive, exchange, subscription or conversion rights and are freely transferable. Each share is entitled to participate equally in dividends and distributions declared by the Board with respect to the relevant fund, and in the net distributable assets of such fund on liquidation.

Each share has one vote with respect to matters upon which the shareholder is entitled to vote. In any matter submitted to shareholders for a vote, each fund shall hold a separate vote, provided that shareholders of all affected funds will vote together when: (1) required by the 1940 Act, or (2) the Trustees determine that the matter affects the interests of more than one fund.

Under Delaware law, the Trust is not required to hold an annual meeting of shareholders unless required to do so under the 1940 Act. The policy of the Trust is not to hold an annual meeting of shareholders unless required to do so under the 1940 Act. All shares (regardless of the fund) have noncumulative voting rights in the election of members of the Board. Under Delaware law, Trustees of the Trust may be removed by vote of the shareholders.

Following the creation of the initial Creation Unit(s) of shares of a fund and immediately prior to the commencement of trading in such fund’s shares, a holder of shares may be a “control person” of the fund, as defined in the 1940 Act. A fund cannot predict the length of time for which one or more shareholders may remain a control person of the fund.

In accordance with the Trust’s Amended and Restated Agreement and Declaration of Trust dated September 17, 2009 (the “Declaration of Trust”), the Board may, without shareholder approval (unless such shareholder approval is required by applicable law, including the 1940 Act), cause one or more funds commencing operations after September 24, 2008 (each, a “New Fund”) to merge, reorganize, consolidate, sell all or substantially all of their assets, or take other similar actions with, to or into another New Fund.

Shareholders may make inquiries by writing to iShares Trust, c/o SEI Investments Distribution Co., One Freedom Valley Drive, Oaks, PA 19456.

Absent an applicable exemption or other relief from the SEC or its staff, beneficial owners of more than 5% of the shares of a fund may be subject to the reporting provisions of Section 13 of the 1934 Act and the SEC’s rules promulgated thereunder. In addition, absent an applicable exemption or other relief from the SEC or its staff, officers and trustees of a fund and beneficial owners of 10% of the shares of a fund (“Insiders”) may be subject to the insider reporting, short-swing profit and short sale provisions of Section 16 of the 1934 Act and the SEC’s rules promulgated thereunder. Beneficial owners and Insiders should consult with their own legal counsel concerning their obligations under Sections 13 and 16 of the 1934 Act.

Termination of the Trust or a Fund. The Trust or a Fund may be terminated by a majority vote of the Board, subject to the affirmative vote of a majority of the shareholders of the Trust or such Fund entitled to vote on termination; however, in certain circumstances described in the Declaration of Trust, only a majority vote of the Board is required. Although the shares are not automatically redeemable upon the occurrence of any specific event, the Declaration of Trust provides that the Board will have the unrestricted power to alter the number of shares in a Creation Unit. In the event of a termination of the Trust or a Fund, the Board, in its sole discretion, could determine to permit the shares to be redeemable in aggregations smaller than Creation Units or to be individually redeemable. In such circumstance, the Trust may make redemptions in-kind, for cash or for a combination of cash or securities.

DTC as Securities Depository for Shares of the Funds. Shares of each Fund are represented by securities registered in the name of DTC or its nominee and deposited with, or on behalf of, DTC.

DTC, a limited-purpose trust company, was created to hold securities of its participants (“DTC Participants”) and to facilitate the clearance and settlement of securities transactions among the DTC Participants in such securities through electronic book-entry changes in accounts of the DTC Participants, thereby eliminating the need for physical movement of securities’ certificates. DTC Participants include securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations, some of whom (and/or their representatives) own DTC. More specifically, DTC is owned by a number of its DTC Participants and by the NYSE, the NYSE Amex Equities and FINRA. Access to the DTC system is also available to others such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a DTC Participant, either directly or indirectly (“Indirect Participants”).

Beneficial ownership of shares is limited to DTC Participants, Indirect Participants and persons holding interests through DTC Participants and Indirect Participants. Ownership of beneficial interests in shares (owners of such beneficial interests are referred to herein as “Beneficial Owners”) is shown on, and the transfer of ownership is effected only through, records maintained by DTC (with respect to DTC Participants) and on the records of DTC Participants (with respect to Indirect Participants and Beneficial Owners that are not DTC Participants). Beneficial Owners will receive from or through the DTC Participant a written confirmation relating to their purchase of shares.

Conveyance of all notices, statements and other communications to Beneficial Owners is effected as follows. Pursuant to the Depositary Agreement between the Trust and DTC, DTC is required to make available to the Trust upon request and for a fee to be charged to the Trust a listing of the shares of each Fund held by each DTC Participant. The Trust shall inquire of each such DTC Participant as to the number of Beneficial Owners holding shares, directly or indirectly, through such DTC Participant. The Trust shall provide each such DTC Participant with copies of such notice, statement or other communication, in such form, number and at such place as such DTC Participant may reasonably request, in order that such notice, statement or communication may be transmitted by such DTC Participant, directly or indirectly, to such Beneficial Owners. In addition, the Trust shall pay to each such DTC Participant a fair and reasonable amount as reimbursement for the expenses attendant to such transmittal, all subject to applicable statutory and regulatory requirements.

Share distributions shall be made to DTC or its nominee, Cede & Co., as the registered holder of all shares of the Trust. DTC or its nominee, upon receipt of any such distributions, shall credit immediately DTC Participants’ accounts with payments in amounts proportionate to their respective beneficial interests in shares of each Fund as shown on the records of DTC or its nominee. Payments by DTC Participants to Indirect Participants and Beneficial Owners of shares held through such DTC Participants will be governed by standing instructions and customary practices, as is now the case with securities held for the accounts of customers in bearer form or registered in a “street name,” and will be the responsibility of such DTC Participants.

The Trust has no responsibility or liability for any aspect of the records relating to or notices to Beneficial Owners, or payments made on account of beneficial ownership interests in such shares, or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests, or for any other aspect of the relationship between DTC and the DTC Participants or the relationship between such DTC Participants and the Indirect Participants and Beneficial Owners owning through such DTC Participants. DTC may decide to discontinue providing its service with respect to shares of the Trust at any time by giving reasonable notice to the Trust and discharging its responsibilities with respect thereto under applicable law. Under such circumstances, the Trust shall take action to find a replacement for DTC to perform its functions at a comparable cost.

Creation and Redemption of Creation Units

General. The Trust issues and sells shares of each Fund only in Creation Units on a continuous basis through the Distributor, without a sales load, at a price based on the Fund’s NAV next determined after receipt, on any Business Day (as defined below), of an order in proper form. The following table sets forth the number of shares of a Fund that constitute a Creation Unit for such Fund and the value of such Creation Unit as of September 30, 2011:

Fund
Shares Per
Creation Unit
Value Per
Creation
Unit (U.S.$)
iShares S&P Conservative Allocation Fund 50,000 $1,429,000.00
iShares S&P Moderate Allocation Fund 50,000 1,440,500.00
iShares S&P Growth Allocation Fund 50,000 1,466,500.00
iShares S&P Aggressive Allocation Fund 50,000 1,510,000.00
iShares S&P Target Date Retirement Income Index Fund 50,000 1,458,500.00
iShares S&P Target Date 2010 Index Fund 50,000 1,484,000.00
iShares S&P Target Date 2015 Index Fund 50,000 1,504,500.00
iShares S&P Target Date 2020 Index Fund 50,000 1,509,000.00
iShares S&P Target Date 2025 Index Fund 50,000 1,509,500.00
iShares S&P Target Date 2030 Index Fund 50,000 1,501,500.00
iShares S&P Target Date 2035 Index Fund 50,000 1,490,500.00
iShares S&P Target Date 2040 Index Fund 50,000 1,493,500.00
iShares S&P Target Date 2045 Index Fund 50,000 1,149,000.00
iShares S&P Target Date 2050 Index Fund 50,000 1,147,000.00

The Board reserves the right to declare a split or a consolidation in the number of shares outstanding of any Fund, and to make a corresponding change in the number of shares constituting a Creation Unit, in the event that the per share price in the secondary market rises (or declines) to an amount that falls outside the range deemed desirable by the Board.

A “Business Day” with respect to each Fund is any day on which the Listing Exchange on which the Fund is listed for trading is open for business. As of the date of this SAI, each Listing Exchange observes the following holidays, as observed: New Year’s Day, Martin Luther King, Jr. Day, Presidents’ Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day.

Fund Deposit. The consideration for purchase of Creation Units of a Fund generally consists of the in-kind deposit of a designated portfolio of securities (including any portion of such securities for which cash may be substituted) (i.e., the Deposit Securities) and the Cash Component computed as described below. Together, the Deposit Securities and the Cash Component constitute the “Fund Deposit,” which when combined with the Fund’s portfolio securities is designed to generate performance that has a collective investment portfolio similar to that of the Underlying Index. The Fund Deposit represents the minimum initial and subsequent investment amount for a Creation Unit of any Fund.

The Cash Component is an amount equal to the difference between the net asset value of the shares (per Creation Unit) and the “Deposit Amount,” which is an amount equal to the market value of the Deposit Securities, and serves to compensate for any differences between the net asset value per Creation Unit and the Deposit Amount. Payment of any stamp duty or other similar fees and expenses payable upon transfer of beneficial ownership of the Deposit Securities are the sole responsibility of the Authorized Participant purchasing a Creation Unit.

BFA makes available through the NSCC on each Business Day, prior to the opening of business on the Listing Exchange, the list of names and the required number of shares of each Deposit Security and the amount of the Cash Component to be included in the current Fund Deposit (based on information as of the end of the previous Business Day) for each Fund. Such Fund Deposit is applicable, subject to any adjustments as described below, in order to effect purchases of Creation Units of shares of a given Fund until such time as the next-announced Fund Deposit is made available.

The identity and number of shares of the Deposit Securities change pursuant to changes in the composition of a Fund’s portfolio and as rebalancing adjustments and corporate action events are reflected from time to time by BFA with a view to the investment objective of the Fund. The composition of the Deposit Securities may also change in response to adjustments to the weighting or composition of the component securities constituting the relevant Underlying Index.

The Funds reserve the right to permit or require the substitution of a “cash in lieu” amount to be added to the Cash Component to replace any Deposit Security that may not be available in sufficient quantity for delivery or that may not be eligible for transfer through DTC. The Funds also reserve the right to permit or require a “cash in lieu” amount in certain circumstances, including circumstances in which (i) the delivery of the Deposit Security by the Authorized Participant (as described below) would be restricted under applicable securities laws or (ii) the delivery of the Deposit Security to the Authorized Participant would result in the disposition of the Deposit Security by the Authorized Participant becoming restricted under applicable securities laws, or in certain other situations.

Role of the Authorized Participant. Creation Units may be purchased only by or through a DTC Participant that has entered into an Authorized Participant Agreement with the Distributor (an “Authorized Participant”). Such Authorized Participant will agree, pursuant to the terms of such Authorized Participant Agreement and on behalf of itself or any investor on whose behalf it will act, to certain conditions, including that such Authorized Participant will make available in advance of each purchase of shares an amount of cash sufficient to pay the Cash Component, once the net asset value of a Creation Unit is next determined after receipt of the purchase order in proper form, together with the transaction fee described below. The Authorized Participant may require the investor to enter into an agreement with such Authorized Participant with respect to certain matters, including payment of the Cash Component. Investors who are not Authorized Participants must make appropriate arrangements with an Authorized Participant. Investors should be aware that their particular broker may not be a DTC Participant or may not have executed an Authorized Participant Agreement and that orders to purchase Creation Units may have to be placed by the investor’s broker through an Authorized Participant. As a result, purchase orders placed through an Authorized Participant may result in additional charges to such investor. The Trust does not expect to enter into an Authorized Participant Agreement with more than a small number of DTC Participants. A list of current Authorized Participants may be obtained from the Distributor.

Purchase Orders. To initiate an order for a Creation Unit, an Authorized Participant must submit to the Distributor an irrevocable order to purchase shares of a Fund generally before 4:00 p.m., Eastern time on any Business Day to receive that day’s NAV. On days when the Listing Exchange or the bond markets close earlier than normal, the Funds may require orders for Creation Units to be placed earlier in the day. The Distributor will notify BFA and the Custodian of such order. The Custodian will then provide such information to any appropriate subcustodian. Procedures and requirements governing the delivery of the Fund Deposit are set forth in the procedures handbook for Authorized Participants and may change from time to time.

Those placing orders to purchase Creation Units through an Authorized Participant should allow sufficient time to permit proper submission of the purchase order to the Distributor by the Cutoff Time (as defined below) on such Business Day.

The Authorized Participant must also make available on or before the contractual settlement date, by means satisfactory to the Funds, immediately available or same day funds estimated by the Funds to be sufficient to pay the Cash Component next determined after acceptance of the purchase order, together with the applicable purchase transaction fees. Any excess funds will be returned following settlement of the issue of the Creation Unit. Those placing orders should ascertain the applicable deadline for cash transfers by contacting the operations department of the broker or depositary institution effectuating the transfer of the Cash Component. This deadline is likely to be significantly earlier than the Cutoff Time (as described below) of the Funds.

The Authorized Participant is responsible for any and all expenses and costs incurred by a Fund, including any applicable cash amounts, in connection with any purchase order.

Investors, other than Authorized Participants, are responsible for making arrangements for a creation request to be made through an Authorized Participant. The Distributor will provide a list of current Authorized Participants upon request. Investors should be aware that an Authorized Participant may require orders for purchases of shares placed with it to be in the particular form required by the individual Authorized Participant.

Timing of Submission of Purchase Orders. An Authorized Participant must submit an irrevocable order to purchase shares of a Fund generally before 4:00 p.m., Eastern time on any Business Day in order to receive that day’s NAV. Each deadline specified above for the submission of purchase orders is referred to as that Fund’s “Cutoff Time.” The Distributor in its discretion may permit the submission of such orders and requests by or through an Authorized Participant at any time (including on days on which the Listing Exchange is not open for business) via communication through the facilities of the Distributor’s proprietary website maintained for this purpose. Purchase orders and redemption requests, if accepted by the Trust, will be processed based on the NAV next determined after such acceptance in accordance with the Trust’s standard Cutoff Times as provided in the Authorized Participant Agreement and disclosed in this SAI.

Acceptance of Orders for Creation Units. Subject to the conditions that (i) an irrevocable purchase order has been submitted by the Authorized Participant (either on its own or another investor’s behalf) and (ii) arrangements satisfactory to the Funds are in place for payment of the Cash Component and any other cash amounts which may be due, the Funds will accept the order, subject to each Fund’s right (and the right of the Distributor and BFA) to reject any order until acceptance.

Once a Fund has accepted an order, upon the next determination of the net asset value of the shares, the Fund will confirm the issuance of a Creation Unit, against receipt of payment, at such net asset value. The Distributor will then transmit a confirmation of acceptance to the Authorized Participant that placed the order.

Each Fund reserves the absolute right to reject or revoke a creation order transmitted to it by the Distributor if (i) the order is not in proper form; (ii) the investor(s), upon obtaining the shares ordered, would own 80% or more of the currently outstanding shares of the Fund; (iii) the Deposit Securities delivered do not conform to the identity and number of shares specified, as described above; (iv) acceptance of the Deposit Securities would have certain adverse tax consequences to the Fund; (v) acceptance of the Fund Deposit would, in the opinion of counsel, be unlawful; (vi) acceptance of the Fund Deposit would, in the discretion of the Fund or BFA, have an adverse effect on the Fund or the rights of beneficial owners; or (vii) circumstances outside the control of the Fund, the Distributor and BFA make it impracticable to process purchase orders. The Distributor shall notify a prospective purchaser of a Creation Unit and/or the Authorized Participant acting on behalf of such purchaser of its rejection of such order. The Funds, State Street, the subcustodian and the Distributor are under no duty, however, to give notification of any defects or irregularities in the delivery of Portfolio Deposits nor shall any of them incur any liability for failure to give such notification.

Issuance of a Creation Unit. Except as provided herein, a Creation Unit will not be issued until the transfer of good title to the Funds of the Deposit Securities and the payment of the Cash Component have been completed. When the subcustodian has confirmed to the Custodian that the securities included in the Fund Deposit (or the cash value thereof) have been delivered

to the account of the relevant subcustodian or subcustodians, the Distributor and BFA shall be notified of such delivery and the applicable Fund will issue and cause the delivery of the Creation Unit. Creation Units typically are issued on a “T+3 basis” (i.e., three Business Days after trade date).

To the extent contemplated by an Authorized Participant’s agreement with the Distributor, each Fund will issue Creation Units to such Authorized Participant, notwithstanding the fact that the corresponding Portfolio Deposits have not been received in part or in whole, in reliance on the undertaking of the Authorized Participant to deliver the missing Deposit Securities as soon as possible, which undertaking shall be secured by such Authorized Participant’s delivery and maintenance of collateral having a value at least equal to 105% and up to 115%, which percentage BFA may change from time to time, of the value of the missing Deposit Securities in accordance with the Funds’ then-effective procedures. The only collateral that is acceptable to the Funds is cash in U.S. dollars. Such cash collateral must be delivered no later than 2:00 p.m., Eastern time on the contractual settlement date. The cash collateral posted by the Authorized Participant may be invested at the risk of the Authorized Participant, and income, if any, on invested cash collateral will be paid to that Authorized Participant. Information concerning the Funds’ current procedures for collateralization of missing Deposit Securities is available from the Distributor. The Authorized Participant Agreement will permit the Funds to buy the missing Deposit Securities at any time and will subject the Authorized Participant to liability for any shortfall between the cost to the Funds of purchasing such securities and the cash collateral.

In certain cases, Authorized Participants may create and redeem Creation Units on the same trade date and in these instances, the Funds reserve the right to settle these transactions on a net basis or require a representation from the Authorized Participants that the creation and redemption transactions are for separate beneficial owners. All questions as to the number of shares of each security in the Deposit Securities and the validity, form, eligibility and acceptance for deposit of any securities to be delivered shall be determined by each Fund and the Fund’s determination shall be final and binding.

Cash Purchase Method. Although the Trust does not ordinarily permit cash purchases of Creation Units of iShares funds, when Creation Units are available or specified for a Fund, they will be effected in essentially the same manner as in-kind purchases thereof. In the case of a cash purchase, the Authorized Participant must pay the cash equivalent of the Deposit Securities it would otherwise be required to provide through an in-kind purchase, plus the same Cash Component required to be paid by an in-kind purchaser.

Costs Associated with Creation Transactions. A standard creation transaction fee is imposed to offset the transfer and other transaction costs associated with the issuance of Creation Units. The standard creation transaction fee will be the same regardless of the number of Creation Units purchased by an Authorized Participant on the applicable Business Day. The Authorized Participant may also be required to cover certain brokerage, tax, foreign exchange, execution, market impact and other costs and expenses related to the execution of trades resulting from such transaction (up to the maximum amount shown below). Authorized Participants will also bear the costs of transferring the Deposit Securities to the Funds. Investors who use the services of a broker or other financial intermediary may be charged a fee for such services.

The following table sets forth each Fund’s standard creation transaction fees and maximum additional charge (as described above):

Redemption of Creation Units. Shares of a Fund may be redeemed by Authorized Participants only in Creation Units at their NAV next determined after receipt of a redemption request in proper form by the Distributor and only on a Business Day. The Funds will not redeem shares in amounts less than Creation Units. There can be no assurance, however, that there will be sufficient liquidity in the secondary market at any time to permit assembly of a Creation Unit. Investors should expect to incur brokerage and other costs in connection with assembling a sufficient number of shares to constitute a Creation Unit that could be redeemed by an Authorized Participant. Beneficial owners also may sell shares in the secondary market.

BFA makes available through the NSCC, prior to the opening of business on the Listing Exchange on each Business Day, the designated portfolio of securities (including any portion of such securities for which cash may be substituted) that will be applicable (subject to possible amendment or correction) to redemption requests received in proper form (as defined below) on that day (“Fund Securities”), and an amount of cash (as described below). Such Fund Securities and the corresponding cash amount are applicable, subject to any adjustments as described below, in order to effect redemptions of Creation Units of a Fund until such time as the next announced composition of the Fund Securities is made available. Fund Securities received on redemption may not be identical to Deposit Securities that are applicable to creations of Creation Units.

Unless cash redemptions are available or specified for a Fund, the redemption proceeds for a Creation Unit generally consist of Fund Securities, plus additional cash in an amount equal to the difference between the net asset value of the shares being redeemed, as next determined after the receipt of a request in proper form, and the value of Fund Securities, less a redemption transaction fee (as described below). The Trust may, in its sole discretion, substitute a “cash in lieu” amount to replace any Fund Security. The amount of cash paid out in such cases will be equivalent to the value of the substituted security listed as a Fund Security. In the event that the Fund Securities have a value greater than the NAV of the shares, a compensating cash payment equal to the difference is required to be made by or through an Authorized Participant by the redeeming shareholder. Each Fund currently redeems shares for Fund Securities, but each Fund reserves the right to utilize a cash option for redemption of shares.

Costs Associated with Redemption Transactions. A standard redemption transaction fee is imposed to offset transfer and other transaction costs that may be incurred by the relevant Fund. The standard redemption transaction fee will be the same regardless of the number of Creation Units redeemed by an Authorized Participant on the applicable Business Day. The Authorized Participant may also be required to cover certain brokerage, tax, foreign exchange, execution, market impact and other costs and expenses related to the execution of trades resulting from such transaction (up to the maximum amount shown below). Authorized Participants will also bear the costs of transferring the Fund Securities from a Fund to their account on their order. Investors who use the services of a broker or other financial intermediary may be charged a fee for such services.

The following table sets forth each Fund’s standard redemption transaction fees and maximum additional charge (as described above):

Placement of Redemption Orders. Redemption requests for Creation Units of any Fund must be submitted to the Distributor by or through an Authorized Participant. An Authorized Participant must submit an irrevocable request to redeem shares of a Fund generally before 4:00 p.m., Eastern time on any Business Day, in order to receive that day’s NAV. Investors other than Authorized Participants are responsible for making arrangements for a redemption request to be made through an Authorized Participant. The Distributor will provide a list of current Authorized Participants upon request.

The Authorized Participant must transmit the request for redemption in the form required by the Funds to the Distributor in accordance with procedures set forth in the Authorized Participant Agreement. Investors should be aware that their particular broker may not have executed an Authorized Participant Agreement and that, therefore, requests to redeem Creation Units may have to be placed by the investor’s broker through an Authorized Participant who has executed an Authorized Participant Agreement. At any time, only a limited number of broker-dealers will have an Authorized Participant Agreement in effect. Investors making a redemption request should be aware that such request must be in the form specified by such Authorized Participant. Investors making a request to redeem Creation Units should allow sufficient time to permit proper submission of the request by an Authorized Participant and transfer of the shares to the Funds’ Transfer Agent; such investors should allow for the additional time that may be required to effect redemptions through their banks, brokers or other financial intermediaries if such intermediaries are not Authorized Participants.

A redemption request is considered to be in “proper form” if (i) an Authorized Participant has transferred or caused to be transferred to the Funds’ Transfer Agent the Creation Unit being redeemed through the book-entry system of DTC so as to be effective by the Listing Exchange closing time on any Business Day, (ii) a request in form satisfactory to the applicable Fund is received by the Distributor from the Authorized Participant on behalf of itself or another redeeming investor within the time periods specified above and (iii) all other procedures set forth in the Authorized Participant Agreement are properly followed. If the Transfer Agent does not receive the investor’s shares through DTC’s facilities by 10:00 a.m., Eastern time on the Business Day next following the day that the redemption request is received, the redemption request shall be rejected. Investors should be aware that the deadline for such transfers of shares through the DTC system may be significantly earlier than the close of business on the Listing Exchange. Those making redemption requests should ascertain the deadline applicable to transfers of shares through the DTC system by contacting the operations department of the broker or depositary institution effecting the transfer of the shares.

Upon receiving a redemption request, the Distributor shall notify the applicable Fund and the Fund’s Transfer Agent of such redemption request. The tender of an investor’s shares for redemption and the distribution of the securities and/or cash redemption included in the payment made in respect of Creation Units redeemed will be made through DTC and the relevant Authorized Participant to the Beneficial Owner thereof as recorded on the book-entry system of DTC or the DTC Participant through which such investor holds, as the case may be, or by such other means specified by the Authorized Participant submitting the redemption request.

A redeeming Beneficial Owner or Authorized Participant acting on behalf of such Beneficial Owner must maintain appropriate security arrangements with a qualified broker-dealer, bank or other custody providers in each jurisdiction in which any of the Portfolio Securities are customarily traded, to which account such Portfolio Securities will be delivered.

Deliveries of redemption proceeds by each Fund generally will be made within three Business Days (i.e., “T+3”).

To the extent contemplated by an Authorized Participant’s agreement with the Distributor, in the event an Authorized Participant has submitted a redemption request in proper form but is unable to transfer all or part of the Creation Unit to be redeemed to the Fund, at or prior to 10:00 a.m., Eastern time on the Listing Exchange business day after the date of submission of such redemption request, the Distributor will accept the redemption request in reliance on the undertaking by

the Authorized Participant to deliver the missing shares as soon as possible. Such undertaking shall be secured by the Authorized Participant’s delivery and maintenance of collateral consisting of cash, in U.S. dollars in immediately available funds, having a value at least equal to 105% and up to 115%, which percentage BFA may change from time to time, of the value of the missing shares. Such cash collateral must be delivered no later than 10:00 a.m., Eastern time on the day after the date of submission of such redemption request and shall be held by State Street and marked-to-market daily. The fees of State Street and any subcustodians in respect of the delivery, maintenance and redelivery of the cash collateral shall be payable by the Authorized Participant. The cash collateral posted by the Authorized Participant may be invested at the risk of the Authorized Participant, and income, if any, on invested cash collateral will be paid to that Authorized Participant. The Authorized Participant Agreement permits the Funds to acquire Fund Securities and the Cash Component underlying such shares at any time and subjects the Authorized Participant to liability for any shortfall between the cost to the Funds of purchasing such shares, Fund Securities or Cash Component and the value of the cash collateral.

The right of redemption may be suspended or the date of payment postponed with respect to any Fund (i) for any period during which the Listing Exchange is closed (other than customary weekend and holiday closings), (ii) for any period during which trading on the Listing Exchange is suspended or restricted, (iii) for any period during which an emergency exists as a result of which disposal of the shares of the Fund’s portfolio securities or determination of its net asset value is not reasonably practicable; or (iv) in such other circumstance as is permitted by the SEC.

Taxation on Creation and Redemptions of Creation Units. An Authorized Participant generally will recognize either gain or loss upon the exchange of Deposit Securities for Creation Units. This gain or loss is calculated by taking the market value of the Creation Units purchased over the Authorized Participant’s aggregate basis in the Deposit Securities exchanged therefor. However, the U.S. Internal Revenue Service (the “IRS”) may apply the wash sales rules to determine that any loss realized upon the exchange of Deposit Securities for Creation Units is not currently deductible. Authorized Participants should consult their own tax advisors.

Current U.S. federal tax laws dictate that capital gain or loss realized from the redemption of Creation Units will generally create long-term capital gain or loss if the Authorized Participant holds the Creation Units for more than one year, or short-term capital gain or loss if the Creation Units were held for one year or less, if the Creation Units are held as capital assets.

Taxes

Regulated Investment Company Qualifications. Each Fund intends to continue to qualify for treatment as a separate RIC under Subchapter M of the Internal Revenue Code. To qualify for treatment as a RIC, each Fund must annually distribute at least 90% of its investment company taxable income (which includes dividends, interest and net short-term capital gains) and meet several other requirements. Among such other requirements are the following: (i) at least 90% of each Fund’s annual gross income must be derived from dividends, interest, payments with respect to securities loans, gains from the sale or other disposition of stock or securities or non-U.S. currencies, other income (including, but not limited to, gains from options, futures or forward contracts) derived with respect to its business of investing in such stock, securities or currencies, and net income derived from interests in qualified publicly-traded partnerships (i.e., partnerships that are traded on an established securities market or tradable on a secondary market, other than partnerships that derive 90% of their income from interest, dividends, capital gains and other traditionally permitted mutual fund income); and (ii) at the close of each quarter of each Fund’s taxable year, (a) at least 50% of the market value of each Fund’s total assets must be represented by cash and cash items, U.S. government securities, securities of other RICs and other securities, with such other securities limited for purposes of this calculation in respect of any one issuer to an amount not greater than 5% of the value of the Fund’s assets and not greater than 10% of the outstanding voting securities of such issuer, and (b) not more than 25% of the value of each Fund’s total assets may be invested in the securities (other than U.S. government securities or the securities of other RICs) of any one issuer, of two or more issuers of which 20% or more of the voting stock is held by the Fund and that are engaged in the same or similar trades or businesses or related trades or businesses, or the securities of one or more qualified publicly-traded partnerships.

Although, in general, the passive loss rules of the Internal Revenue Code do not apply to RICs, such rules do apply to a RIC with respect to items attributable to interests in qualified publicly-traded partnerships. A Fund’s investments in partnerships, including in qualified publicly-traded partnerships, may result in a Fund being subject to state, local, or non-U.S. income, franchise or withholding tax liabilities.

Taxation of RICs. As a RIC, a Fund will not be subject to U.S. federal income tax on the portion of its taxable investment income and capital gains that it distributes to its shareholders, provided that it satisfies a minimum distribution requirement. To satisfy the minimum distribution requirement, a Fund must distribute to its shareholders at least the sum of (i) 90% of its “investment company taxable income” (i.e., income other than its net realized long-term capital gain over its net realized short-term capital loss), plus or minus certain adjustments, and (ii) 90% of its net tax-exempt income for the taxable year. A Fund will be subject to income tax at regular corporate rates on any taxable income or gains that it does not distribute to its shareholders. If a Fund fails to qualify for any taxable year as a RIC or fails to meet the distribution requirement, all of its taxable income will be subject to tax at regular corporate income tax rates without any deduction for distributions to shareholders, and such distributions generally will be taxable to shareholders as ordinary dividends to the extent of the Fund’s current and accumulated earnings and profits. In such event, distributions to individuals should be eligible to be treated as qualified dividend income and distributions to corporate shareholders generally should be eligible for the dividends received deduction. Although each Fund intends to distribute substantially all of its net investment income and its capital gains for each taxable year, each Fund will be subject to U.S. federal income taxation to the extent any such income or gains are not distributed. If a Fund fails to qualify as a RIC in any year, it must pay out its earnings and profits accumulated in that year in order to qualify again as a RIC. If a Fund fails to qualify as a RIC for a period greater than two taxable years, the Fund may be required to recognize any net built-in gains with respect to certain of its assets (i.e., the excess of the aggregate gains, including items of income, over aggregate losses that would have been realized with respect to such assets if the Fund had been liquidated) if it qualifies as a RIC in a subsequent year.

Excise Tax. A Fund will be subject to a 4% excise tax on certain undistributed income if it does not distribute to its shareholders in each calendar year at least 98% of its ordinary income for the calendar year plus 98.2% of its capital gain net income for the 12 months ended October 31 of such year. For this purpose, however, any ordinary income or capital gain net income retained by a Fund that is subject to corporate income tax will be considered to have been distributed by year-end. In addition, the minimum amounts that must be distributed in any year to avoid the excise tax will be increased or decreased to reflect any underdistribution or overdistribution, as the case may be, from the previous year. Each Fund intends to declare and distribute dividends and distributions in the amounts and at the times necessary to avoid the application of this 4% excise tax. Long-term capital distributions from the Underlying Funds paid in December or, in certain cases, January in satisfaction of this rule will be subject to potential distribution by the Funds in the following calendar year.

Net Capital Loss Carryforwards. Net capital loss carryforwards may be applied against any net realized capital gains in each succeeding year, until they have been reduced to zero.

The following Funds had tax basis net capital loss carryforwards as of July 31, 2011, the tax year-end for the Funds:

Taxation of U.S. Shareholders. Dividends and other distributions by a Fund are generally treated under the Internal Revenue Code as received by the shareholders at the time the dividend or distribution is made. However, any dividend or distribution declared by a Fund in October, November or December of any calendar year and payable to shareholders of record on a specified date in such a month shall be deemed to have been received by each shareholder on December 31 of such calendar year and to have been paid by the Fund not later than such December 31, provided such dividend is actually paid by the Fund during January of the following calendar year.

Each Fund intends to distribute annually to its shareholders substantially all of its investment company taxable income and any net realized long-term capital gains in excess of net realized short-term capital losses (including any capital loss carryovers). However, if a Fund retains for investment an amount equal to all or a portion of its net long-term capital gains in excess of its net short-term capital losses (including any capital loss carryovers), it will be subject to a corporate tax

(currently at a maximum rate of 35%) on the amount retained. In that event, the Fund will designate such retained amounts as undistributed capital gains in a notice to its shareholders who (a) will be required to include in income for U.S. federal income tax purposes, as long-term capital gains, their proportionate shares of the undistributed amount, (b) will be entitled to credit their proportionate shares of the 35% tax paid by the Fund on the undistributed amount against their U.S. federal income tax liabilities, if any, and to claim refunds to the extent their credits exceed their liabilities, if any, and (c) will be entitled to increase their tax basis, for U.S. federal income tax purposes, in their shares by an amount equal to 65% of the amount of undistributed capital gains included in the shareholder’s income. Organizations or persons not subject to U.S. federal income tax on such capital gains will be entitled to a refund of their pro rata share of such taxes paid by the Fund upon filing appropriate returns or claims for refund with the IRS.

Distributions of net realized long-term capital gains, if any, that a Fund reports as capital gains dividends are taxable as long-term capital gains, whether paid in cash or in shares and regardless of how long a shareholder has held shares of the Fund. All other dividends of a Fund (including dividends from short-term capital gains) from its current and accumulated earnings and profits (“regular dividends”) are generally subject to tax as ordinary income, subject to the discussion of qualified dividend income below. Short-term capital gain earned by an Underlying Fund will be ordinary income when distributed to a Fund and will not be offset by the Fund’s capital losses.

If an individual receives a regular dividend qualifying for the long-term capital gains rates and such dividend constitutes an “extraordinary dividend,” and the individual subsequently recognizes a loss on the sale or exchange of stock in respect of which the extraordinary dividend was paid, then the loss will be long-term capital loss to the extent of such extraordinary dividend. An “extraordinary dividend” on common stock for this purpose is generally a dividend (i) in an amount greater than or equal to 10% of the taxpayer’s tax basis (or trading value) in a share of stock, aggregating dividends with ex-dividend dates within an 85-day period, or (ii) in an amount greater than 20% of the taxpayer’s tax basis (or trading value) in a share of stock, aggregating dividends with ex-dividend dates within a 365-day period.

Distributions in excess of a Fund’s current and accumulated earnings and profits will, as to each shareholder, be treated as a tax-free return of capital to the extent of a shareholder’s basis in shares of the Fund, and as a capital gain thereafter (if the shareholder holds shares of the Fund as capital assets). Shareholders receiving dividends or distributions in the form of additional shares should be treated for U.S. federal income tax purposes as receiving a distribution in an amount equal to the amount of money that the shareholders receiving cash dividends or distributions will receive and should have a cost basis in the shares received equal to such amount. Dividends paid by an Underlying Fund that are attributable to dividends received by a Fund from domestic corporations may qualify for the federal dividends received deduction for corporations.

Beginning in 2013, a 3.8% U.S. federal Medicare contribution tax will be imposed on net investment income, including interest, dividends, and capital gain, of U.S. individuals with income exceeding $200,000 (or $250,000 if married and filing jointly), and of estates and trusts.

Investors considering buying shares just prior to a dividend or capital gain distribution should be aware that, although the price of shares purchased at that time may reflect the amount of the forthcoming distribution, such dividend or distribution may nevertheless be taxable to them. If a Fund is the holder of record of any security on the record date for any dividends payable with respect to such security, such dividends will be included in the Fund’s gross income not as of the date received but as of the later of (a) the date such security became ex-dividend with respect to such dividends (i.e., the date on which a buyer of the security would not be entitled to receive the declared, but unpaid, dividends); or (b) the date the Fund acquired such security. Accordingly, in order to satisfy its income distribution requirements, a Fund may be required to pay dividends based on anticipated earnings, and shareholders may receive dividends in an earlier year than would otherwise be the case.

In certain situations, a Fund may, for a taxable year, defer all or a portion of its capital losses and currency losses realized after October and certain ordinary losses realized after December until the next taxable year in computing its investment company taxable income and net capital gain, which will defer the recognition of such realized losses. Such deferrals and other rules regarding gains and losses realized after October (or December) may affect the tax character of shareholder distributions.

Sales of Shares. Upon the sale or exchange of shares of a Fund, a shareholder will realize a taxable gain or loss equal to the difference between the amount realized and the shareholder’s basis in shares of the Fund. A redemption of shares by a Fund will be treated as a sale for this purpose. Such gain or loss will be treated as capital gain or loss if the shares are capital assets in the shareholder’s hands and will be long-term capital gain or loss if the shares are held for more than one year and short-term capital gain or loss if the shares are held for one year or less. Any loss realized on a sale or exchange will be disallowed to the extent the shares disposed of are replaced, including replacement through the reinvesting of dividends and capital

gains distributions in the Funds, within a 61-day period beginning 30 days before and ending 30 days after the disposition of the shares. In such a case, the basis of the shares acquired will be increased to reflect the disallowed loss. Any loss realized by a shareholder on the sale of Fund shares held by the shareholder for six months or less will be treated for U.S. federal income tax purposes as a long-term capital loss to the extent of any distributions or deemed distributions of long-term capital gains received by the shareholder with respect to such share. The Medicare contribution tax described above will apply to the sale of Fund shares.

If a shareholder incurs a sales charge in acquiring shares of a Fund, disposes of those shares within 90 days and then, on or before January 31 of the following calendar year, acquires shares in a mutual fund for which the otherwise applicable sales charge is reduced by reason of a reinvestment right (e.g., an exchange privilege), the original sales charge will not be taken into account in computing gain/loss on the original shares to the extent the subsequent sales charge is reduced. Instead, the disregarded portion of the original sales charge will be added to the tax basis of the newly acquired shares. Furthermore, the same rule also applies to a disposition of the newly acquired shares made within 90 days of the second acquisition. This provision prevents shareholders from immediately deducting the sales charge by shifting their investments within a family of mutual funds.

Back-Up Withholding. In certain cases, a Fund will be required to withhold at the applicable withholding rate, and remit to the U.S. Treasury such amounts withheld from any distributions paid to a shareholder who: (i) has failed to provide a correct taxpayer identification number; (ii) is subject to back-up withholding by the IRS; (iii) has failed to certify to a Fund that such shareholder is not subject to back-up withholding; or (iv) has not certified that such shareholder is a U.S. person (including a U.S. resident alien). Back-up withholding is not an additional tax and any amount withheld may be credited against a shareholder’s U.S. federal income tax liability.

Sections 351 and 362. The Trust, on behalf of each Fund, has the right to reject an order for a purchase of shares of the Fund if the purchaser (or group of purchasers) would, upon obtaining the shares so ordered, own 80% or more of the outstanding shares of a given Fund and if, pursuant to Sections 351 and 362 of the Internal Revenue Code, that Fund would have a basis in the securities different from the market value of such securities on the date of deposit. If a Fund’s basis in such securities on the date of deposit was less than market value on such date, the Fund, upon disposition of the securities, would recognize more taxable gain or less taxable loss than if its basis in the securities had been equal to market value. It is not anticipated that the Trust will exercise the right of rejection except in a case where the Trust determines that accepting the order could result in material adverse tax consequences to a Fund or its shareholders. The Trust also has the right to require information necessary to determine beneficial share ownership for purposes of the 80% determination.


Taxation of Certain Derivatives. An Underlying Fund’s transactions in zero coupon securities, non-U.S. currencies, forward contracts, options and futures contracts (including options and futures contracts on non-U.S. currencies), to the extent permitted, will be subject to special provisions of the Internal Revenue Code (including provisions relating to “hedging transactions” and “straddles”) that, among other things, may affect the character of gains and losses realized by the Fund (i.e., may affect whether gains or losses are ordinary or capital), accelerate recognition of income to the Fund and defer Fund losses. These rules could therefore affect the character, amount and timing of distributions to shareholders. These provisions also (a) will require an Underlying Fund to mark-to-market certain types of the positions in its portfolio (i.e., treat them as if they were closed out at the end of each year) and (b) may cause an Underlying Fund to recognize income without receiving cash with which to pay dividends or make distributions in amounts necessary to satisfy the distribution requirements for avoiding income and excise taxes. Each Underlying Fund will monitor its transactions, will make the appropriate tax elections and will make the appropriate entries in its books and records when it acquires any zero coupon security, non-U.S. currency, forward contract, option, futures contract or hedged investment in order to mitigate the effect of these rules and prevent disqualification of the Underlying Fund as a RIC.

An Underlying Fund’s investments in so-called “Section 1256 contracts,” such as regulated futures contracts, most non-U.S. currency forward contracts traded in the interbank market and options on most security indexes, are subject to special tax rules. All Section 1256 contracts held by an Underlying Fund at the end of its taxable year are required to be marked to their market value, and any unrealized gain or loss on those positions will be included in the Underlying Fund’s income as if each position had been sold for its fair market value at the end of the taxable year. The resulting gain or loss will be combined with any gain or loss realized by the Underlying Fund from positions in Section 1256 contracts closed during the taxable year. Provided such positions were held as capital assets and were not part of a “hedging transaction” nor part of a “straddle,”

60% of the resulting net gain or loss will be treated as long-term capital gain or loss, and 40% of such net gain or loss will be treated as short-term capital gain or loss, regardless of the period of time the positions were actually held by the Underlying Fund.

As a result of entering into swap contracts, an Underlying Fund may make or receive periodic net payments. An Underlying Fund may also make or receive a payment when a swap is terminated prior to maturity through an assignment of the swap or other closing transaction. Periodic net payments will generally constitute ordinary income or deductions, while termination of a swap will generally result in capital gain or loss (which will be a long-term capital gain or loss if the Underlying Fund has been a party to the swap for more than one year). With respect to certain types of swaps, an Underlying Fund may be required to currently recognize income or loss with respect to future payments on such swaps or may elect under certain circumstances to mark such swaps to market annually for tax purposes as ordinary income or loss.

Qualified Dividend Income. Distributions by a Fund of investment company taxable income (including any short-term capital gains), whether received in cash or shares, will be taxable either as ordinary income or as qualified dividend income, eligible for the reduced maximum rate to individuals of 15% (0% for individuals in lower tax brackets) to the extent the Fund receives qualified dividend income from the Underlying Funds and the Fund reports the distribution as qualified dividend income. Qualified dividend income is, in general, dividend income from taxable U.S. corporations (but generally not from U.S. real estate investment trusts (“REITs”)) and certain non-U.S. corporations (e.g., non-U.S. corporations that are not “passive foreign investment companies” and which are incorporated in a possession of the United States or in certain countries with a comprehensive tax treaty with the United States, or the stock of which is readily tradable on an established securities market in the United States (where the dividends are paid with respect to such stock)). Under current IRS guidance, the United States has appropriate comprehensive income tax treaties with the following countries: Australia, Austria, Bangladesh, Barbados, Belgium, Bulgaria, Canada, China (but not with Hong Kong which is treated as a separate jurisdiction for U.S. tax purposes), Cyprus, the Czech Republic, Denmark, Egypt, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, India, Indonesia, Ireland, Israel, Italy, Jamaica, Japan, Kazakhstan, Latvia, Lithuania, Luxembourg, Malta, Mexico, Morocco, the Netherlands, New Zealand, Norway, Pakistan, the Philippines, Poland, Portugal, Romania, Russia, the Slovak Republic, Slovenia, South Africa, South Korea, Spain, Sri Lanka, Sweden, Switzerland, Thailand, Trinidad and Tobago, Tunisia, Turkey, Ukraine, the United Kingdom and Venezuela. Substitute payments received by a Fund for securities lent out by the Fund will not be qualified dividend income.

A dividend from a Fund will not be treated as qualified dividend income to the extent that (i) the shareholder has not held the shares on which the dividend was paid for 61 days during the 121-day period that begins on the date that is 60 days before the date on which the shares become ex-dividend with respect to such dividend or the Fund fails to satisfy those holding period requirements with respect to the Underlying Fund that paid the dividend or the Underlying Fund fails to satisfy those holding period requirements with respect to the securities it holds that paid the dividends distributed to the shareholder (or, in the case of certain preferred stocks, the holding requirement of 91 days during the 181-day period beginning on the date that is 90 days before the date on which the stock becomes ex-dividend with respect to such dividend); (ii) the Underlying Fund, the Fund or the shareholder is under an obligation (whether pursuant to a short sale or otherwise) to make related payments with respect to substantially similar or related property; or (iii) the shareholder elects to treat such dividend as investment income under Section 163(d)(4)(B) of the Internal Revenue Code. Dividends received by a Fund from a REIT or another RIC may be treated as qualified dividend income only to the extent the dividend distributions are attributable to qualified dividend income received by such REIT or other RIC. It is expected that dividends received by a Fund from a REIT and distributed to a shareholder generally will be taxable to the shareholder as ordinary income. The maximum 15% rate on qualified dividend income will not apply to dividends received in taxable years beginning after December 31, 2012. Distributions by a Fund of its net short-term capital gains will be taxable as ordinary income. Capital gain distributions consisting of a Fund’s net capital gains will be taxable as long-term capital gains.

If you lend your Fund shares pursuant to securities lending arrangements, you may lose the ability to use non-U.S. tax credits passed through by the Fund or to treat Fund dividends (paid while the shares are held by the borrower) as qualified dividends. Consult your financial intermediary or tax advisor. If you enter into a short sale with respect to shares of the Fund, substitute payments made to the lender of such shares may not be deductible.

Corporate Dividends Received Deduction. Dividends paid by a Fund that are attributable to dividends received by the Fund from the Underlying Funds and that are attributable to dividends paid by U.S. corporations may qualify for the U.S. federal dividends received deduction for corporations. A 46-day minimum holding period during the 90-day period that begins 45

days prior to ex-dividend date (or 91-day minimum holding period during the 180 period beginning 90 days prior to ex-dividend date for certain preference dividends) during which risk of loss may not be diminished is required for the applicable shares, at the Fund level, the Underlying Fund level and shareholder level, for a dividend to be eligible for the dividends received deduction. Restrictions may apply if indebtedness, including a short sale, is attributable to the investment.

Excess Inclusion Income. Under current law, the Funds serve to block unrelated business taxable income from being realized by their tax-exempt shareholders. Notwithstanding the foregoing, a tax-exempt shareholder could realize unrelated business taxable income by virtue of its investment in a Fund if shares in the Fund constitute debt-financed property in the hands of the tax-exempt shareholder within the meaning of Section 514(b) of the Internal Revenue Code. Certain types of income received by an Underlying Fund from REITs, real estate mortgage investment conduits, taxable mortgage pools or other investments may cause the Fund to report some or all of its distributions as “excess inclusion income.” To Fund shareholders, such excess inclusion income may (i) constitute taxable income, as unrelated business taxable income for those shareholders who would otherwise be tax-exempt such as individual retirement accounts, 401(k) accounts, Keogh plans, pension plans and certain charitable entities; (ii) not be offset by otherwise allowable deductions for tax purposes; (iii) not be eligible for reduced U.S. withholding for non-U.S. shareholders even from tax treaty countries; and (iv) cause the Fund or Underlying Fund to be subject to tax if certain “disqualified organizations,” as defined by the Internal Revenue Code, are Fund shareholders. If a charitable remainder annuity trust or a charitable remainder unitrust (each as defined in Section 664 of the Internal Revenue Code) has unrelated business taxable income (“UBTI”) for a taxable year, a 100% excise tax on the UBTI is imposed on the trust.

Non-U.S. Investments. Under Section 988 of the Internal Revenue Code, gains or losses attributable to fluctuations in exchange rates between the time an Underlying Fund accrues income or receivables or expenses or other liabilities denominated in a non-U.S. currency and the time the Underlying Fund actually collects such income or pays such liabilities are generally treated as ordinary income or ordinary loss. In general, gains (and losses) realized on debt instruments will be treated as Section 988 gain (or loss) to the extent attributable to changes in exchange rates between the U.S. dollar and the currencies in which the instruments are denominated. Similarly, gains or losses on non-U.S. currency, non-U.S. currency forward contracts and certain non-U.S. currency options or futures contracts denominated in non-U.S currency, to the extent attributable to fluctuations in exchange rates between the acquisition and disposition dates, are also treated as ordinary income or loss unless the Underlying Fund were to elect otherwise.

The Underlying Funds, if invested in non-U.S. securities, may be subject to non-U.S. income taxes. Each Underlying Fund that is permitted to do so may elect to “pass through” to its investors, including the Funds, the amount of non-U.S. income taxes paid by the Underlying Fund. The Funds will be themselves eligible to elect to pass-through such amounts to their stockholders and may do so, depending upon circumstances.

Passive Foreign Investment Companies. If an Underlying Fund purchases shares in “passive foreign investment companies” (“PFICs”), it may be subject to U.S. federal income tax on a portion of any “excess distribution” or gain from the disposition of such shares even if such income is distributed as a taxable dividend by the Fund to its shareholders. Additional charges in the nature of interest may be imposed on the Fund in respect of deferred taxes arising from such distributions or gains.

If an Underlying Fund were to invest in a PFIC and elect to treat the PFIC as a “qualified electing fund” under the Internal Revenue Code, in lieu of the foregoing requirements, the Underlying Fund might be required to include in income each year a portion of the ordinary earnings and net capital gains of the qualified electing fund, even if not distributed to the Underlying Fund, and such amounts would be subject to the 90% and excise tax distribution requirements described above. In order to make this election, the Underlying Fund would be required to obtain certain annual information from the PFICs in which it invests, which may be difficult or impossible to obtain.

Alternatively, an Underlying Fund may make a mark-to-market election that would result in the Underlying Fund being treated as if it had sold and repurchased its PFIC stock at the end of each year. In such case, the Underlying Fund would report any such gains as ordinary income and would deduct any such losses as ordinary losses to the extent of previously recognized gains. The election must be made separately for each PFIC owned by the Underlying Fund and, once made, would be effective for all subsequent taxable years, unless revoked with the consent of the IRS. By making the election, the Underlying Fund could potentially ameliorate the adverse tax consequences with respect to its ownership of shares in a PFIC, but in any particular year may be required to recognize income in excess of the distributions it receives from PFICs and its proceeds from dispositions of PFIC stock. The Underlying Fund may have to distribute this “phantom” income and gain to satisfy the 90% distribution requirement and to avoid imposition of the 4% excise tax.

An Underlying Fund will make the appropriate tax elections, if possible, and take any additional steps that are necessary to mitigate the effects of these rules.

Reporting. If a shareholder recognizes a loss with respect to a Fund’s shares of $2 million or more for an individual shareholder or $10 million or more for a corporate shareholder, the shareholder must file with the IRS a disclosure statement on Form 8886. Direct shareholders of portfolio securities are in many cases exempted from this reporting requirement, but under current guidance, shareholders of a RIC are not exempted. The fact that a loss is reportable under these regulations does not affect the legal determination of whether the taxpayer’s treatment of the loss is proper. Shareholders should consult their tax advisors to determine the applicability of these regulations in light of their individual circumstances.

Other Taxes. Dividends, distributions and redemption proceeds may also be subject to additional state, local and non-U.S. taxes depending on each shareholder’s particular situation.

Taxation of Non-U.S. Shareholders. Dividends paid by a Fund to non-U.S. shareholders are generally subject to withholding tax at a 30% rate or a reduced rate specified by an applicable income tax treaty to the extent derived from investment income and short-term capital gains. Dividends paid by a Fund from net tax-exempt income or long-term capital gains are generally not subject to such withholding tax. In order to obtain a reduced rate of withholding, a non-U.S. shareholder will be required to provide an IRS Form W-8BEN certifying its entitlement to benefits under a treaty. The withholding tax does not apply to regular dividends paid to a non-U.S. shareholder who provides a Form W-8ECI, certifying that the dividends are effectively connected with the non-U.S. shareholder’s conduct of a trade or business within the United States. Instead, the effectively connected dividends will be subject to regular U.S. income tax as if the non-U.S. shareholder were a U.S. shareholder. A non-U.S. corporation receiving effectively connected dividends may also be subject to additional “branch profits tax” imposed at a rate of 30% (or lower treaty rate). A non-U.S. shareholder who fails to provide an IRS Form W-8BEN or other applicable form may be subject to back-up withholding at the appropriate rate.

In general, U.S. federal withholding tax will not apply to any gain or income realized by a non-U.S. shareholder in respect of any distributions of net long-term capital gains over net short-term capital losses, tax-exempt interest dividends, or upon the sale or other disposition of shares of a Fund. If a Fund’s direct or indirect interests in U.S. real property were to exceed certain levels, distributions to a non-U.S. shareholder from a Fund attributable to a REIT’s distribution to a Fund of gain from a sale or exchange of a U.S. real property interest and, in the case of a non-U.S. shareholder owning more than 5% of the class of shares throughout either such person’s holding period for the redeemed shares or, if shorter, the previous five years, the gain on redemption will be treated as real property gain subject to additional taxes or withholding and may result in the non-U.S. shareholder having additional filing requirements.

For taxable years beginning before January 1, 2012, distributions that a Fund reports as “short-term capital gain dividends” or “long-term capital gain dividends” are not treated as such to a recipient non-U.S. shareholder if the distribution is attributable to gain received from the sale or exchange of U.S. real property or an interest in a U.S. real property holding corporation and a Fund’s direct or indirect interests in U.S. real property exceed certain levels. Instead, if the non-U.S. shareholder has not owned more than 5% of the outstanding shares of a Fund at any time during the one year period ending on the date of distribution, such distribution is subject to 30% withholding by a Fund and is treated as ordinary dividends to the non-U.S. shareholder; if the non-U.S. shareholder owned more than 5% of the outstanding shares of a Fund at any time during the one year period ending on the date of the distribution, such distribution is treated as real property gain subject to 35% withholding tax and could subject the non-U.S. shareholder to U.S. filing requirements. Additionally, if a Fund’s direct or indirect interests in U.S. real property were to exceed certain levels, a non-U.S. shareholder realizing gains upon redemption from a Fund on or before December 31, 2011 could be subject to the 35% withholding tax and U.S. filing requirements unless more than 50% of a Fund’s shares were owned by U.S. persons at such time or unless the non-U.S. person had not held more than 5% of a Fund’s outstanding shares throughout either such person’s holding period for the redeemed shares or, if shorter, the previous five years.

The rules laid out in the previous two paragraphs, other than the withholding rules, will apply notwithstanding the Fund’s participation in a wash sale transaction or its payment of a substitute dividend.

Provided that 50% or more of the value of the Fund’s stock is held by U.S. shareholders, distributions of U.S. real property interests (including securities in a U.S. real property holding corporation, unless such corporation is regularly traded on an established securities market and the Fund has held 5% or less of the outstanding shares of the corporation during the five-year period ending on the date of distribution) occurring on or before December 31, 2011, in redemption of a foreign shareholder’s shares of the Fund will cause the Fund to recognize gain. If the Fund is required to recognize gain, the amount

of gain recognized will be equal to the fair market value of such interests over the Fund’s adjusted bases to the extent of the greatest foreign ownership percentage of the Fund during the five-year period ending on the date of redemption.

For taxable years beginning before January 1, 2012, properly reported dividends are generally exempt from U.S. federal withholding tax where they (i) are paid in respect of a Fund’s “qualified net interest income” (generally, a Fund’s U.S. source interest income, other than certain contingent interest and interest from obligations of a corporation or partnership in which a Fund is at least a 10% shareholder, reduced by expenses that are allocable to such income), or (ii) are paid in respect of a Fund’s “qualified short-term capital gains” (generally, the excess of a Fund’s net short-term capital gain over a Fund’s long-term capital loss for such taxable year). However, depending on its circumstances, a Fund may report all, some or none of its potentially eligible dividends as such qualified net interest income or as qualified short-term capital gains and/or treat such dividends, in whole or in part, as ineligible for this exemption from withholding. In order to qualify for this exemption from withholding, a non-U.S. shareholder will need to comply with applicable certification requirements relating to its non-U.S. status (including, in general, furnishing an IRS Form W-8BEN or substitute Form). In the case of shares held through an intermediary, the intermediary may withhold even if a Fund reports the payment as qualified net interest income or qualified short-term capital gain. Non-U.S. shareholders should contact their intermediaries with respect to the application of these rules to their accounts.

A 30% withholding tax will be imposed on dividends paid after December 31, 2013, and redemption proceeds paid after December 31, 2014, to (i) foreign financial institutions, including non-U.S. investment funds, unless they agree to collect and disclose to the IRS information regarding their direct and indirect U.S. account holders; and (ii) certain other foreign entities, unless they certify certain information regarding their direct and indirect U.S. owners. To avoid withholding, foreign financial institutions will need to enter into agreements with the IRS that state that they will provide the IRS information, including the name, address and taxpayer identification number of direct and indirect U.S. account holders; comply with due diligence procedures with respect to the identification of U.S. accounts; report to the IRS certain information with respect to U.S. accounts maintained; agree to withhold tax on certain payments made to non-compliant foreign financial institutions or to account holders who fail to provide the required information; and determine certain other information as to their account holders. Other foreign entities will need to provide the name, address, and taxpayer identification number of each substantial U.S. owner or certifications of no substantial U.S. ownership, unless certain exceptions apply.

Shares of a Fund held by a non-U.S. shareholder at death will be considered situated within the United States and subject to the U.S. estate tax for decedents dying after December 31, 2011, with a lookthrough rule applying before such date.

The foregoing discussion is a summary of certain material U.S. federal income tax considerations only and is not intended as a substitute for careful tax planning. Purchasers of shares should consult their own tax advisors as to the tax consequences of investing in such shares, including consequences under state, local and non-U.S. tax laws. Finally, the foregoing discussion is based on applicable provisions of the Internal Revenue Code, regulations, judicial authority and administrative interpretations in effect on the date of this SAI. Changes in applicable authority could materially affect the conclusions discussed above, and such changes often occur.

Appendix A

DESCRIPTION OF FIXED-INCOME RATINGS

A rating is generally assigned to a fixed-income security at the time of issuance by a credit rating agency designated as a nationally recognized statistical rating organization (“NRSRO”) by the SEC. While NRSROs may from time to time revise such ratings, they undertake no obligation to do so, and the ratings given to securities at issuance do not necessarily represent ratings which would be given to these securities on a particular subsequent date.

Fixed-income securities which are unrated expose the investor to risks with respect to capacity to pay interest or repay principal which are similar to the risks of lower-rated speculative bonds. Evaluation of these securities is dependent on the investment adviser’s judgment, analysis and experience in the evaluation of such securities.

Investors should note that the assignment of a rating to a security by an NRSRO may not reflect the effect of recent developments on the issuer’s ability to make interest and principal payments or on the likelihood of default.

The descriptions below relate to general long-term and short-term obligations of an issuer.

Moody’s Ratings

Long-Term Obligations

Aaa: Obligations rated Aaa are judged to be of the highest quality, with minimal credit risk.

Aa: Obligations rated Aa are judged to be of high quality and are subject to very low credit risk.

A: Obligations rated A are considered upper-medium grade and are subject to low credit risk.

Baa: Obligations rated Baa are subject to moderate credit risk. They are considered medium grade and as such may possess certain speculative characteristics.

Ba: Obligations rated Ba are judged to have speculative elements and are subject to substantial credit risk.

B: Obligations rated B are considered speculative and are subject to high credit risk.

Caa: Obligations rated Caa are judged to be of poor standing and are subject to very high credit risk.

Ca: Obligations rated Ca are highly speculative and are likely in, or very near, default, with some prospect of recovery of principal and interest.

C: Obligations rated C are the lowest rated class and are typically in default, with little prospect for recovery of principal or interest.

Note: Moody’s appends numerical modifiers 1, 2 and 3 in each generic rating classification from Aa through Caa. The modifier 1 indicates that the obligation ranks in the higher end of its generic rating category; the modifier 2 indicates a mid-range ranking; and the modifier 3 indicates a ranking in the lower end of that generic rating category.

Absence of Rating: Where no rating has been assigned or where a rating has been withdrawn, it may be for reasons unrelated to the credit worthiness of the issue.

Should no rating be assigned, the reason may be one of the following:

1. An application was not received or accepted.

2. The issue or issuer belongs to a group of securities or entities that are not rated as a matter of policy.

3. There is a lack of essential data pertaining to the issue or issuer.

4. The issue was privately placed, in which case the rating is not published in Moody’s publications.



A-1   


Table Of Contents



Withdrawal may occur if new and material circumstances arise, the effects of which preclude satisfactory analysis; if there is no longer available reasonable up-to-date data to permit a judgment to be formed; if a bond is called for redemption; or for other reasons.

Short-Term Obligations

Moody’s short-term debt ratings are opinions of the ability of issuers to honor short-term financial obligations, generally with an original maturity not exceeding thirteen months.

Moody’s employs the following designations to indicate the relative repayment ability of rated issuers:

P-1: Issuers (or supporting institutions) rated Prime-1 have a superior ability to repay short-term debt obligations.

P-2: Issuers (or supporting institutions) rated Prime-2 have a strong ability to repay short-term debt obligations.

P-3: Issuers (or supporting institutions) rated Prime-3 have an acceptable ability to repay short-term obligations.

NP: Issuers (or supporting institutions) rated Not Prime do not fall within any of the Prime rating categories.

Standard & Poor’s Ratings

Long-Term Obligations

AAA: An obligation rated AAA has the highest rating assigned by S&P. The obligor’s capacity to meet its financial commitment on the obligation is extremely strong.

AA: An obligation rated AA differs from the highest rated obligations only to a small degree. The obligor’s capacity to meet its financial commitment is very strong.

A: An obligation rated A is somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher rated categories. However, the obligor’s capacity to meet its financial commitment on the obligation is still strong.

BBB: An obligation rated BBB exhibits adequate protection parameters. However, adverse economic conditions or changing circumstances are more likely to lead to a weakened capacity of the obligor to meet its financial commitment on the obligation.

Obligations rated BB, B, CCC, CC, and C are regarded as having significant speculative characteristics. BB indicates the least degree of speculation and C the highest. While such obligations will likely have some quality and protective characteristics, these may be outweighed by large uncertainties or major exposures to adverse conditions.

BB: An obligation rated BB is less vulnerable to nonpayment than other speculative issues. However, it faces major ongoing uncertainties or exposure to adverse business, financial, or economic conditions which could lead to the obligor’s inadequate capacity to meet its financial commitment on the obligation.

B: An obligation rated B is more vulnerable to nonpayment than obligations rated BB, but the obligor currently has the capacity to meet its financial commitment on the obligation. Adverse business, financial, or economic conditions will likely impair the obligor’s capacity or willingness to meet its financial commitment on the obligation.

CCC: An obligation rated CCC is currently vulnerable to nonpayment, and is dependent upon favorable business, financial, and economic conditions for the obligor to meet its financial commitment on the obligation. In the event of adverse business, financial, or economic conditions, the obligor is not likely to have the capacity to meet its financial commitment on the obligation.

CC: An obligation rated CC is currently highly vulnerable to nonpayment.

C: A C rating is assigned to obligations that are currently highly vulnerable to nonpayment, obligations that have payment arrearages allowed by the terms of the documents, or obligations of an issuer that is the subject of a bankruptcy petition or similar action which have not experienced a payment default.



A-2   


Table Of Contents



D: An obligation rated D is in payment default. The D rating category is used when payments on an obligation are not made on the date due even if the applicable grace period has not expired, unless S&P believes that such payments will be made during such grace period. The D rating also will be used upon the filing of a bankruptcy petition or the taking of similar action if payments on an obligation are jeopardized. An obligation’s rating is lowered to D upon completion of a distressed exchange offer, whereby some or all of the issue is either repurchased for an amount of cash or replaced by other instruments having a total value that is less than par.

Note: The ratings from AA to CCC may be modified by the addition of a plus (+) or minus (-) sign to show relative standing within the major rating categories.

NR: NR indicates no rating has been requested, that there is insufficient information on which to base a rating, or that S&P does not rate a particular obligation as a matter of policy.

Short-Term Obligations

A-1: A short-term obligation rated A-1 is rated in the highest category by S&P. The obligor’s capacity to meet its financial commitment on the obligation is strong. Within this category, certain obligations are designated with a plus sign (+). This indicates that the obligor’s capacity to meet its financial commitment on these obligations is extremely strong.

A-2: A short-term obligation rated A-2 is somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than obligations in higher rating categories. However, the obligor’s capacity to meet its financial commitment on the obligation is satisfactory.

A-3: A short-term obligation rated A-3 exhibits adequate protection parameters. However, adverse economic conditions or changing circumstances are more likely to lead to a weakened capacity of the obligor to meet its financial commitment on the obligation.

B: A short-term obligation rated B is regarded as having significant speculative characteristics. Ratings of B-1, B-2, and B-3 may be assigned to indicate finer distinctions within the B category. The obligor currently has the capacity to meet its financial commitment on the obligation; however, it faces major ongoing uncertainties which could lead to the obligor’s inadequate capacity to meet its financial commitment on the obligation.

B-1: A short-term obligation rated B-1 is regarded as having significant speculative characteristics, but the obligor has a relatively stronger capacity to meet its financial commitments over the short-term compared to other speculative-grade obligors.

B-2: A short-term obligation rated B-2 is regarded as having significant speculative characteristics, and the obligor has an average speculative-grade capacity to meet its financial commitments over the short-term compared to other speculative-grade obligors.

B-3: A short-term obligation rated B-3 is regarded as having significant speculative characteristics, and the obligor has a relatively weaker capacity to meet its financial commitments over the short-term compared to other speculative-grade obligors.

C: A short-term obligation rated C is currently vulnerable to nonpayment and is dependent upon favorable business, financial, and economic conditions for the obligor to meet its financial commitment on the obligation.

D: A short-term obligation rated D is in payment default. The D rating category is used when payments on an obligation, including a regulatory capital instrument, are not made on the date due even if the applicable grace period has not expired, unless S&P believes that such payments will be made during such grace period. The D rating also will be used upon the filing of a bankruptcy petition or the taking of a similar action if payments on an obligation are jeopardized.

Fitch Ratings

Long-Term Obligations

AAA: Highest credit quality. AAA ratings denote the lowest expectation of credit risk. They are assigned only in cases of exceptionally strong capacity for payment of financial commitments. This capacity is highly unlikely to be adversely affected by foreseeable events.



A-3   


Table Of Contents



AA: Very high credit quality. AA ratings denote expectations of very low credit risk. They indicate very strong capacity for payment of financial commitments. This capacity is not significantly vulnerable to foreseeable events.

A: High credit quality. “A” ratings denote expectations of low credit risk. The capacity for payment of financial commitments is considered strong. This capacity may, nevertheless, be more vulnerable to adverse business or economic conditions than is the case for higher ratings.

BBB: Good credit quality. BBB ratings indicate that expectations of credit risk are currently low. The capacity for payment of financial commitments is considered adequate, but adverse business or economic conditions are more likely to impair this capacity.

BB: Speculative. BB ratings indicate an elevated vulnerability to credit risk, particularly in the event of adverse changes in business or economic conditions over time; however, business or financial alternatives may be available to allow financial commitments to be met.

B: Highly speculative. B ratings indicate that material credit risk is present.

CCC: Substantial credit risk. CCC ratings indicate that substantial credit risk is present.

CC: Very high levels of credit risk. CC ratings indicate very high levels of credit risk.

C: Exceptionally high levels of credit risk. C indicates exceptionally high levels of credit risk.

Defaulted obligations typically are not assigned D ratings, but are instead rated in the B to C rating categories, depending upon their recovery prospects and other relevant characteristics. This approach better aligns obligations that have comparable overall expected loss but varying vulnerability to default and loss.

Note:

The modifiers “+” or “-” may be appended to a rating to denote relative status within major rating categories. Such suffixes are not added to the AAA obligation rating category, or to corporate finance obligation ratings in the categories below B.

“NR” indicates that Fitch does not rate the issuer or issue in question.

“Withdrawn”: A rating is withdrawn when Fitch deems the amount of information available to be inadequate for rating purposes, or when an obligation matures, is called, or refinanced.

Short-Term Obligations (Corporate and Public Finance)

Short-term ratings are assigned to obligations whose initial maturity is viewed as “short term” based on market convention. Typically, this means up to 13 months for corporate, sovereign, and structured obligations, and up to 36 months for obligations in U.S. public finance markets.

F1: Highest short-term credit quality. Indicates the strongest intrinsic capacity for timely payment of financial commitments; may have an added “+” to denote any exceptionally strong credit feature.

F2: Good short-term credit quality. Good intrinsic capacity for timely payment of financial commitments.



A-4   


Table Of Contents



F3: Fair short-term credit quality. The intrinsic capacity for timely payment of financial commitments is adequate.

B: Speculative short-term credit quality. Minimal capacity for timely payment of financial commitments, plus heightened vulnerability to near term adverse changes in financial and economic conditions.

C: High short-term default risk. Default is a real possibility.

RD: Restricted default. Indicates an entity that has defaulted on one or more of its financial commitments, although it continues to meet other financial obligations. Applicable to entity ratings only.

D: Default. Indicates a broad-based default event for an entity, or the default of a short-term obligation.

Dominion Bond Rating Service Limited


Long-Term Obligations


AAA: Highest credit quality. The capacity for the payment of financial obligations is exceptionally high and unlikely to be adversely affected by future events.


AA: Superior credit quality. The capacity for the payment of financial obligations is considered high. Credit quality differs from AAA only to a small degree. Unlikely to be significantly vulnerable to future events.


A: Good credit quality. The capacity for the payment of financial obligations is substantial, but of lesser credit quality than AA. May be vulnerable to future events, but qualifying negative factors are considered manageable.


BBB: Adequate credit quality. The capacity for the payment of financial obligations is considered acceptable. May be vulnerable to future events.


BB: Speculative, non investment-grade credit quality. The capacity for the payment of financial obligations is uncertain. Vulnerable to future events.


B: Highly speculative credit quality. There is a high level of uncertainty as to the capacity to meet financial obligations.


CCC / CC / C: Very highly speculative credit quality. In danger of defaulting on financial obligations. There is little difference between these three categories, although CC and C ratings are normally applied to obligations that are seen as highly likely to default, or subordinated to obligations rated in the CCC to B range. Obligations in respect of which default has not technically taken place but is considered inevitable may be rated in the C category.


D: A financial obligation has not been met or it is clear that a financial obligation will not be met in the near future or a debt instrument has been subject to a distressed exchange. A downgrade to D may not immediately follow an insolvency or restructuring filing as grace periods or extenuating circumstances may exist.


Note: All rating categories other than AAA and D also contain subcategories “(high)” and “(low)”. The absence of either a “(high)” or “(low)” designation indicates the rating is in the middle of the category.


Commercial Paper and Short-Term Debt


R-1 (high): Highest credit quality. The capacity for the payment of short-term financial obligations as they fall due is exceptionally high. Unlikely to be adversely affected by future events.


R-1 (middle): Superior credit quality. The capacity for the payment of short-term financial obligations as they fall due is very

high. Differs from R-1 (high) by a relatively modest degree. Unlikely to be significantly vulnerable to future events.


R-1 (low): Good credit quality. The capacity for the payment of short-term financial obligations as they fall due is substantial. Overall strength is not as favorable as higher rating categories. May be vulnerable to future events, but qualifying negative factors are considered manageable.
R-2 (high): Upper end of adequate credit quality. The capacity for the payment of short-term financial obligations as they fall due is acceptable. May be vulnerable to future events.


R-2 (middle): Adequate credit quality. The capacity for the payment of short-term financial obligations as they fall due is acceptable. May be vulnerable to future events or may be exposed to other factors that could reduce credit quality.


R-2 (low): Lower end of adequate credit quality. The capacity for the payment of short-term financial obligations as they fall due is acceptable. May be vulnerable to future events. A number of challenges are present that could affect the issuer’s ability to meet such obligations.


R-3: Lowest end of adequate credit quality. There is a capacity for the payment of short-term financial obligations as they fall due. May be vulnerable to future events and the certainty of meeting such obligations could be impacted by a variety of developments.


R-4: Speculative credit quality. The capacity for the payment of short-term financial obligations as they fall due is uncertain.


R-5: Highly speculative credit quality. There is a high level of uncertainty as to the capacity to meet short-term financial obligations as they fall due.


D: A financial obligation has not been met or it is clear that a financial obligation will not be met in the near future, or a debt instrument has been subject to a distressed exchange. A downgrade to D may not immediately follow an insolvency or restructuring filing as grace periods, other procedural considerations, or extenuating circumstance may exist.

Prior to December 1, 2009, BTC was known as Barclays Global Investors, N.A.


Item 29. Persons Controlled By or Under Common Control with Registrant:

None.

Item 30. Indemnification:

The Trust (also referred to in this section as the “Fund”) is organized as a Delaware statutory trust and is operated pursuant to an Amended and Restated Agreement and Declaration of Trust (the “Declaration of Trust”) that permits the Trust to indemnify its trustees and officers under certain circumstances. Such indemnification, however, is subject to the limitations imposed by the Securities Act of 1933, as amended (the “1933 Act”), and the Investment Company Act of 1940 (the “1940 Act”). The Declaration of Trust provides that officers and trustees of the Trust shall be indemnified by the Trust against liabilities and expenses incurred or paid in connection with any claim, action, suit, or proceedings against them by reason of the fact that they each serve as an officer or trustee of the Trust or as an officer or trustee of another entity at the request of the entity. This indemnification is subject to the following conditions:

(a) no trustee or officer of the Trust is indemnified against any liability to the Trust or its security holders that was the result of any willful misfeasance, bad faith, gross negligence, or reckless disregard of the duties involved in the conduct of his office; and

(b) officers and trustees of the Trust are indemnified only for actions taken in good faith that the officers and trustees believed were in or not opposed to the best interests of the Trust.

The Declaration of Trust provides that if indemnification is not ordered by a court, indemnification may be authorized upon determination by shareholders, or by a majority vote of a quorum of the trustees who were not parties to the proceedings or, if this quorum is not obtainable, if directed by a quorum of disinterested trustees, or by independent legal counsel in a written opinion, that the persons to be indemnified have met the applicable standard.

The Amended and Restated By-Laws provides that the Trust may purchase and maintain insurance on behalf of any Covered Person or employee of the Trust, including any Covered Person or employee of the Trust who is or was serving at the request of the Trust as a trustee, officer, or employee of a corporation, partnership, association, joint venture, trust, or other enterprise, against any liability asserted against and incurred by such Covered Person or employee in any such capacity or arising out of his or her status as such, whether or not the trustees would have the power to indemnify him or her against such liability. The Trust may not acquire or obtain a contract for insurance that protects or purports to protect any trustee or officer of the Trust against any liability to the Trust or its Shareholders to which such trustee or officer otherwise would be subject by reason of willful misfeasance, bad faith, gross negligence, or reckless disregard of the duties involved in the conduct of his or her office.

The Master Services Agreement provides that State Street will indemnify, defend and hold harmless the applicable Fund, its Affiliates, and its respective officers, directors, employees, agents and permitted successors and assigns from any and all damages, fines, penalties, deficiencies, losses, liabilities (including judgments and amounts reasonably paid in settlement) and expenses (including interest, court costs, reasonable fees and expenses of attorneys, accountants and other experts or other reasonable fees and expenses of litigation or other proceedings or of any claim, default or assessment) (“Losses”) arising from or in connection with any third party claim or threatened third party claim to the extent that such Losses are based on or arising out of any of the following: (a) breach by State Street or any State Street Personnel of any of its data protection, information security or confidentiality obligations hereunder or under a Service Module to which such Fund is a signatory; (b) any claim of infringement or misappropriation of any Intellectual Property Right alleged to have occurred because of systems or other Intellectual Property provided by or on behalf of State Street or based upon the performance of the Services (collectively, the “State Street Infringement Items”), except to the extent that such infringement or misappropriation relates to or results from; (i) changes made by any Fund or by a third party at the direction of a Fund to the State Street Infringement Items; (ii) changes to the State Street Infringement Items recommended by State Street and not made due to a request from any Fund, provided that State Street has notified such Fund that failure to implement such recommendation would result in infringement within a reasonable amount of time for such Fund to so implement following such notification; (iii) any Fund’s combination of the State Street Infringement Items with products or services not provided or approved in writing by State Street, except to the extent such combination arises out of any Fund’s use of the State Street Infringement Items in a manner consistent with the applicable business requirements documentation; (iv) designs or specifications that in themselves infringe and that are provided by or at the direction of any Fund (except in the event of a knowing infringement by State Street); or (v) use by a Fund of any of the State Street Infringement Items in a manner that is not consistent with the applicable business requirements documentation or otherwise not permitted under the Master Services Agreement or any Service Module; (c) any claim or action by, on behalf of, or related to, any prospective, then-current or former employees of State Street, arising from or in connection with a Service Module to which a Fund is a signatory, including: (i) any claim arising under occupational health and safety, worker’s compensation, ERISA or other applicable Law; (ii) any claim arising from the interview or hiring practices, actions or omissions of employees of State Street; (iii) any claim relating to any violation by employees of State Street, or its respective officers, directors, employees, representatives or agents, of any Law or any common law protecting persons or members of protected classes or categories, such laws or regulations prohibiting discrimination or harassment on the basis of a protected characteristic; and (iv) any claim based on a theory that such Fund


is an employer or joint employer of any such prospective, then-current or former employees of State Street; (d) the failure by State Street to obtain, maintain, or comply with any governmental approvals as required under the Master Services Agreement and/or a Service Module to which such Fund is a signatory or such other failures as otherwise agreed by the Parties from time to time; (e) claims by third parties arising from claims by governmental authorities against such Customer for fines, penalties, sanctions, late fees or other remedies to the extent arising from or in connection with State Street’s failure to perform its responsibilities under the Master Services Agreement or any Service Module (except to the extent a Fund is not permitted as a matter of public policy to have such an indemnity for financial penalties arising from criminal actions); (f) claims by clients of State Street relating to services, products or systems provided by State Street or a Subcontractor to such client(s) in a shared or leveraged environment; (g) any claim initiated by an Affiliate or potential or actual Subcontractor of State Street asserting rights in connection with a Service Module to which such Fund is a signatory; or (h) other claims as otherwise agreed by the Parties from time to time.

The Distribution Agreement provides that SEI agrees to indemnify, defend and hold the Fund, its several officers and Board members, and any person who controls the Fund within the meaning of Section 15 of the 1933 Act, free and harmless from and against any and all claims, demands, liabilities and expenses (including the cost of investigating or defending such claims, demands or liabilities and any counsel fees incurred in connection therewith) which the Fund, its officers or Board members, or any such controlling person, may incur under the 1933 Act, the 1940 Act, or under common law or otherwise, but only to the extent that such liability or expense incurred by the Fund, its officers or Board members, or such controlling person resulting from such claims or demands, (a) shall arise out of or be based upon any information, statements or representations made or provided by SEI in any sales literature or advertisements, or any Disqualifying Conduct by SEI in connection with the offering and sale of any Shares, (b) shall arise out of or be based upon any untrue, or alleged untrue, statement of a material fact contained in information furnished in writing by SEI to the Fund specifically for use in the Fund’s registration statement and used in the answers to any of the items of the registration statement or in the corresponding statements made in the prospectus or statement of additional information, or shall arise out of or be based upon any omission, or alleged omission, to state a material fact in connection with such information furnished in writing by SEI to the Fund and required to be stated in such answers or necessary to make such information not misleading, (c) arising out of SEI’s breach of any obligation, representation or warranty pursuant to this Agreement, or (d) SEI’s failure to comply in any material respect with applicable securities laws.

The Authorized Participant Agreement provides that the Authorized Participant (the “Participant”) agrees to indemnify and hold harmless the Fund and its respective subsidiaries, affiliates, directors, officers, employees and agents, and each person, if any, who controls such persons within the meaning of Section 15 of the 1933 Act (each an “Indemnified Party”) from and against any loss, liability, cost and expense (including attorneys’ fees) incurred by such Indemnified Party as a result of (i) any breach by the Participant of any provision of the Authorized Participant Agreement that relates to the Participant; (ii) any failure on the part of the Participant to perform any of its obligations set forth in the Authorized Participant Agreement; (iii) any failure by the Participant to comply with applicable laws, including rules and regulations of self-regulatory organizations; or (iv) actions of such Indemnified Party in reliance upon any instructions issued in accordance with Annex II, III or IV (as each may be amended from time to time) of the Authorized Participant Agreement reasonably believed by the distributor and/or the transfer agent to be genuine and to have been given by the Participant.

The Amended and Restated Securities Lending Agency Agreement provides that BTC shall indemnify and hold harmless each client, Lender, its Board of Trustees and its agents and BFA and any investment adviser for the Funds from any and all loss, liability, costs, damages, actions, and claims (“Loss”) to the extent that any such Loss arises out of the material breach of this Agreement by or negligent acts or omissions or willful misconduct of BTC, its officers, directors or employees or any of its agents or subcustodians in connection with the securities lending activities undertaken pursuant to this Agreement, provided that BTC’s indemnification obligation with respect to the acts or omissions of its subcustodians shall not exceed the indemnification provided by the applicable subcustodian to BTC.

Insofar as indemnification for liabilities arising under the 1940 Act may be permitted to directors, officers and controlling persons of the Trust pursuant to foregoing provisions, or otherwise, the Trust has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the 1940 Act and is, therefore, unenforceable. In the event that a claim for Fund expenses incurred or paid by a director, officer or controlling person of the Fund in the successful defense of any action, suit or proceeding is asserted by such director, officer or controlling person in connection with the securities being registered, the Trust will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question of whether such indemnification by it is against public policy as expressed in the 1940 Act and will be governed by the final adjudication of such issue.

Item 31. Business and Other Connections of the Investment Adviser:

The Trust is advised by BFA, a wholly-owned subsidiary of BTC, 400 Howard Street, San Francisco, CA 94105. BFA’s business is that of a registered investment adviser to certain open-end, management investment companies and various other institutional investors.


The directors and officers of BFA consist primarily of persons who during the past two years have been active in the investment management business.
